Description

Fire training exercise device

The present invention relates to a drill device for training people to fight fires.

Known devices of this type include devices adapted to create a real fire by directing the fire to a fuel, for example gas delivered by a burner. During training, trainees must endeavor to extinguish fires as quickly and effectively as possible using appropriate fire extinguishers.

Of course, this operation must be carried out under the supervision and control of the instructor and supervisor.

For example, documents US 4 303 396 and EP 0 146 465 relate to stationary and mobile (mounted in truck) training devices respectively.

More precisely, the apparatus of the present invention is designed to be used for training people to fight fires caused by simulated hydrocarbons, the apparatus comprising:

- a fire site consisting of a gas burner submerged in water contained in a pan;

- means for supplying the burner with a mixture of air and a combustible gas such as propane; and

- An electrode suitable for directing the fire to the gas at the beginning of the maneuver.

The electrode is a double electrode of known type operating at high voltage, the discharge spark between the two electrodes igniting the mixture of combustible gas and air exiting the burner face.

The state of the art in this field can be illustrated by document FR-2 814 845.

In order to ignite the mixture, it is advisable to install the device in such a way that the active part of the electrode (where the spark is generated) is at a short distance from the area of the burner where the combustible gas is discharged.

And here comes the problem.

Firstly, once ignition has occurred, the electrodes are exposed to the flame, which leads to the risk of scorching, and thus hazards due to high temperatures.

Second, the electrodes are also exposed to the extinguishing media applied during the drill, such as water and powder.

Once the trainee has completed the maneuver, this exposure jeopardizes the proper functioning of the electrode, making it unusable for firing another ignition.

This hazard occurs especially if the electrodes are wet or powder is deposited in the gap between the anode and cathode.

For the maneuvers to run smoothly, it is important that, as soon as one maneuver is over, another firing can be carried out quickly and automatically by means of the control circuit provided for this purpose.

Those disadvantages are avoided in the device of the above-mentioned document FR-2 814 845, in fact, the electrode is a movable electrode, adapted to be moved away from the burner before the maneuvers start, and adapted to be retracted during the maneuvers.

The electrode can be moved by a pneumatic drive.

The electrode is therefore out of reach of the flame and extinguishing medium during the drill.

As soon as the drill is over, the electrode is moved back to its working position for lighting a new fire.

That known device is generally satisfactory.

However, this device requires moving elements that are more costly and less robust than equivalent stationary elements, and require ongoing maintenance.

In addition, the pneumatic transmission is relatively long, and its presence on the side of the disc can cause certain configurational difficulties, especially when it is necessary to place the disc against a side wall of the exercise area or place the disc on the side of said area. When in a corner.

An object of the present invention is to solve these problems.

The present invention achieves this object by the fact that it provides an ignition device comprising a housing placed near said disc, which housing has a thermally protected inner space and is equipped with heat-resistant ducts, For example a conduit made of stainless steel, the free end of which opens at a short distance above the surface of the water contained in the pan, while inside the casing, the following means are provided: firstly a device suitable for blowing a combustible gas mixture into said conduit , such as a device for blowing a mixture of propane and air; and secondly, a spark plug equipped with electrodes extending axially within the conduit, spanning only a part of the length of the conduit.

The device is therefore stationary.

The volume required for the housing is small compared to the volume required for the disc.

A thermally insulated casing and conduits protect all functional parts of the ignition, especially the electrodes.

The spark necessary for ignition is not generated near the burner, but inside the conduit to ignite the combustible mixture passing through the conduit.

Thus, the flame exiting the duct ignites the burner in the form of a blowtorch.

As soon as the disc is ignited, the supply of combustible gas and, optionally, the supply of air to the device is interrupted.

The catheter remains in place above the disc, its presence out of the way of the drill, and the electrodes are inside the catheter and out of reach of the fire.

The conduit thus acts as a protective sheath, protecting the electrodes from exposure to flames, which would create a risk of scorching, and also pose a hazard due to the high temperature.

The electrodes are also outside the reach of the extinguishing medium used during the extinguishing process.

Additionally, according to some non-limiting preferred features of the present invention:

- the means for blowing a mixture of combustible gas and air to the duct is a hollow body with inlets for combustible gas and air;

- the device also includes monitoring means for monitoring the presence of a flame inside the conduit, such as an ultraviolet radiation detector, said monitoring means being located inside said housing at the entrance to said conduit;

- said conduit is in the shape of a nozzle, the free end of which is bent downwards so as to open near the surface of the water contained in the dish;

- supplying said burner with a mixture of combustible gas and air through a gooseneck-shaped conduit;

- the device also includes monitoring means, such as ultraviolet radiation detectors, for monitoring the extinguishment of the flame present in the pan;

- the device also includes monitoring means for monitoring the extinguishment of the flame present in the tray, such as at least one temperature sensor, for example constituted by a detector of the thermocouple type, connected to an intelligent sensor adapted to detect in real time in the vicinity of the fire and record temperature readings;

- the device also includes a control circuit adapted to automatically cut off the supply of combustible gas to the burner, after a certain period of time after the start of ignition, if it has not been detected that the flame in the pan has been extinguished;

- the combustible gas is conveyed from a compressed container, the air is conveyed by a blower, and mixed through a T-joint, in which the air supply duct extends vertically into the combustible gas supply duct;

- supplying air to the device through a supply duct connected to the air inlet and supplying it with air by means of the blower;

- supplying combustible gas to said device through a supply conduit connected to the combustible gas inlet and to which combustible gas is supplied from a compression vessel;

- the casing is equipped with a regulating element for regulating the flow rate of the combustible gas allowed to enter the device in order to blow a mixture of combustible gas and air into said duct;

- air is supplied to the device through at least one adjustable flow rate air inlet installed in the wall of the housing;

- said housing is lined with a layer of thermal insulation material; and

-The burner is made of braided stainless steel fibers.

Other characteristics and advantages of the invention emerge from the following detailed description with reference to the accompanying drawings, which show a possible embodiment by way of non-limiting example.

In these figures:

Fig. 1 is a general overview of the whole device;

Fig. 2 has shown the general diagram of the axial section of the ignition system that this device is equipped with on a larger scale;

Figure 3 is a detailed view of the T-junction between the gas and air supply pipes;

Figure 4 is a schematic diagram of a fire scene showing the mode of operation of the device;

Figure 5 is a circuit diagram of the monitoring and control circuit of the present invention.

In Fig. 1, reference numeral 1 designates a bottle of combustible gas, propane in this embodiment. As an indicator, the air pressure in the bottle is in the range of about 7-17 bar.

Reference numeral 2 refers to a known type of blower adapted to deliver a flow of air at a pressure slightly above atmospheric pressure.

Reference numeral 3 refers to a coupling, as described below, which connects the propane and air ducts together to supply the combustible gas mixture to the drill fire.

The fire site consists of a burner 5 submerged in water E contained in a tank or pan 4 placed horizontally on a support, for example standing on the ground. The submerged burner 5 is a porous horizontal plate, for example made of woven stainless steel mesh, the upper surface of which is of the "multi-flame" type, making it possible to spread the flame over the entire upper surface of the burner.

The disc 4 can be of any shape, eg round, square or rectangular (viewed from above). It is relatively shallow compared to its horizontal dimensions.

Reference numeral 6 designates a spark plug which has two electrodes and which is arranged in a housing 7 on the side of the disk 4 .

For example, the casing is a rectangular block or a tube.

As a guideline, each side of the housing measures approximately 300 millimeters (mm).

The walls of the housing are heat-resistant, eg made of stainless steel.

Compared with the size of the disk 4, the size of the housing is relatively small, and its size is appropriately enlarged in FIG. 1 only to improve the clarity of the illustration.

In FIG. 2 it can be seen that the space in the housing 7 is thermally protected by a lining 700 of a known type of material having good thermal insulating properties, for example a lining based on mineral fibres.

The housing 7 is provided with a heat-resistant pipe 71, for example made of stainless steel. The tube extends horizontally across the upper end of the wall of the pan 4 and its free end 710 bends slightly downwards, opening a short distance above the surface of the water E contained in the pan 4 .

The free end 710 points approximately toward the central region of the submerged burner 5 .

As an indicator, the tube 71 has a length in the range of approximately 300-600 mm, a diameter in the range of approximately 50-60 mm, and it extends a distance above the water surface in the range of approximately 50-200 mm.

The tubes 71 are fitted in a vacuum-tight manner by suitable means (not shown) into holes of corresponding cross-section provided in one wall of the housing 1 .

Said housing comprises a device 70 suitable for blowing a combustible gas mixture, for example a mixture of propane and air, into a tube 71 and a spark plug equipped with an electrode 6 .

Said device 70 is a hollow body having a circular tubular body portion 72 axially extended by a tube 78 of smaller diameter within said tube 71 and having a diameter significantly larger than that of tube 71. Be small.

The free end 780 of the tube 78 flares outward.

The common axis of the portions 72 and 78 is horizontal and therefore parallel to the axis of the tube 71 .

Tube 78 extends within tube 71 across only a part of its length, for example across a third of its length.

An ignition spark plug 6 is mounted on the end of the portion 72 located in the housing 7, which end is opposite to the end of the tube 78 which extends outwardly. The spark plug is provided with a rigid, filamentary, rectilinear double electrode 62 extending axially within tubular elements 72 and 78 . Its free end is located in the flared portion 780 of the tube 78 .

Suitable fixed holding means (not shown) firstly hold the device 70 in place in the housing 7 and secondly ensure that the electrodes 62 are properly centered on the tubular elements 72 and 78 .

Reference numerals 60 and 61 designate, respectively, a high-voltage current generator and an electrical conductor, which energize the spark plug 6 via a contactor 610 . Contactor 610 is, for example, a switch controlled by an electromagnet.

The device 70 has inlets for combustible gas and for air.

These inlets are formed by inlet nozzles 730 and 720 connected to the main body portion 72 .

The air inlet nozzle 720 is located upstream of the combustible gas inlet in consideration of the direction in which the mixed gas is blown into the pipe 71 through the pipe 78 . The axis of the air inlet nozzle 720 is perpendicular to the axis of the main body portion 72 .

The axis of the combustible gas nozzle 730 forms an acute angle α with the axis of the main body portion 72, the apex of which is directed downstream.

The nozzle 730 extends upstream through a conduit 73 to a connection end piece 170 which is supported by a wall of the housing 7 . A suitable means for regulating the gas flow rate is mounted on said conduit 73, which means is shown in the figure by a chamber 74 containing a movable regulating plate, for example controlled by a cam.

The conduit 73 is connected to a combustible gas supply conduit 17 via a fitting 170 .

Nozzle 720 extends upstream through a short conduit 76 , the inlet of which is located in housing 70 .

The conduit 76 is either connected to the air supply conduit 22 as shown in FIGS. 1 and 2 , or remains free so that it communicates with the air present in the housing 7 .

Reference numerals 8a, 8b (Figs. 1 and 4) refer to ultraviolet radiation detectors, which correspond to the respective areas of the fire scene.

Of course, more than two detectors may be used, depending on the size of the disc 4 and the difficulty with which the maneuver is performed.

They are UV detectors of a known type, utilizing tubes that are insensitive to solar and electro-optical radiation, but are adapted to detect UV radiation from flames.

When said radiation disappears due to the partial extinguishing of the flame, the detectors in this area react, said detectors emitting an appropriate electronic signal, which is received by the circuit 80 .

A similar ultraviolet radiation detector 8c is installed in the housing 7 for detecting the presence of a flame in the conduit 71 .

Reference numerals 90 and 91 refer to a propane detector and a carbon monoxide (CO) detector, respectively.

Electronic signals corresponding to each of these types of detectors are sent to an appropriate operating circuit 9 .

Reference numeral 93 refers to a temperature sensor placed near the fire site, which is used to stop combustion when the temperature exceeds a set threshold value, as described below.

Reference numeral 92 refers to a fan suitable for ventilating the area L containing the burners and in which the maneuvers are performed.

Reference numeral 8d refers to a temperature sensor consisting of a thermocouple suitable for detecting negative temperature gradients in the immediate vicinity of the fire.

For example, it may be a thermocouple of the commercial model "TC5-30-Klnc-P" type sold by the French company "PYRO-SYSTEMS", having a length equal to 100 mm and a diameter equal to 3 mm, which has a maximum operating temperature of 1100°C.

The sensor 8d is integrally formed with the upper surface of the burner 5 .

Provided in at least one wall of the housing is a pair of apertures 77 and 77' which are adapted to be closed to varying degrees by respective tabs 76 and 76', or which are adapted to remain open.

These two holes are the air intake vents used to allow air to enter the case.

If the conduit 22 is not connected to said conduit 76, this pair of holes allows air to be brought from the outside into the inlet of the conduit 76 at an adjustable flow rate.

In FIG. 1, reference numerals 15 and 16 denote propane supply pipes delivered at medium pressure and low pressure, respectively.

The direction of flow of propane is indicated by arrow P.

Reference numeral 11 refers to a safety component comprising a pressure reducing valve, which reduces the pressure of the propane delivered from the bottle 1, for example to a pressure of about 1.5 bar in the conduit 15 .

The reference numerals 10a and 10b respectively located upstream and downstream of the element 11 refer to manual shut-off valves.

Reference numeral 12 also refers to a safety component comprising a pressure reducing valve, whose function is to further reduce the pressure of propane to a relatively low pressure, for example in the range of about 30-300 mbar, selected The pressure depends on the type of fire applied and the size and power of the burner 5. As an indicator, the power may be in the range of 50-150 kW.

Reference numerals 10c and 10d are manual shut-off valves upstream and downstream of component 12, respectively.

Reference numeral 13 refers to a minimum gas pressure switch, and reference numeral 14 refers to a solenoid valve.

Whenever the gas pressure falls below a set threshold value, for example due to clogging of an upstream filter, the pressure switch 13 automatically closes the solenoid valve 14 in a known manner.

In addition, the solenoid valve 14 is controlled by the monitoring and control circuit of the device as described below.

The blower 2 delivers air into the duct 20 at a pressure slightly above atmospheric pressure.

The direction of air flow into said duct 20 is indicated by arrow A. As shown in FIG.

Reference numeral 21 refers to a manually actuated valve (controlled at will) or an electric valve (controlled automatically), which can be used to allow the air delivered by the blower 2 to escape to the outside if necessary, for example when the solenoid valve 14 is closed ( prevent the supply of burner air only).

It can be seen from FIG. 3 that the conduit 20 penetrates deep into the conduit 16, thereby forming a T-shaped junction indicated by 3, in which the gaseous propane flow P and the air flow X are mixed, and the flow of the mixed gas is indicated by the arrow M in FIGS. 1 and 3 .

An air supply conduit 22 for supplying air into the device 70 is connected to the conduit 20 upstream of the junction 3 .

Downstream of said connection, the mixed gas is fed via a gooseneck-shaped conduit 30 to a connecting conduit 31 connected to the burner 5 .

The upper part of the part 30 extends above the water surface, and its gooseneck shape prevents the water E contained in the pan 4 from flowing back into the mixed gas supply pipe.

The conduit 31 passes in a sealed manner through the bottom of the disc 4 by putting in a suitable gasket.

This is shown in Figure 4, where the arrow i indicates multiple air streams exiting the burner upwards, simultaneously causing a (shallow) volume of water above the burner to boil.

When the combustible gas is ignited, the flame f is distributed over the entire surface of the disc, thus simulating a hydrocarbon fire.

By changing the relative proportions of propane and air, the color of the flame can be changed.

A ratio of 20% air to 80% propane results in a red-yellow phase flame, similar to a hydrocarbon flame.

As an indicator, the depth of the water E in the pan 4 is approximately in the range of 15-20 cm, the thickness of the burner 5 is in the range of 8-15 mm, and the depth of the water above the burner is approximately in the range of 4-5 cm.

However, as an indicator, if the burner is circular, its diameter is, for example, approximately 60 cm.

Of course, other dimensions may be chosen, depending on the maneuvers being performed.

The device is also equipped with a solenoid valve 18 .

A propane supply conduit 17 for supplying propane to the ignition 70 is connected to the conduit 16 at a point between the pressure switch 13 and the solenoid valve 14 .

Before the exercise begins, the inventory will be taken using the device 70 .

Turn on Blower 2 and open all propane supply valves so that:

- the gas mixture is supplied to the burner 5 through the duct 31 (figure 1, arrow M);

- propane is supplied to the device 7 through the conduit 17 and the nozzle 730 (Fig. 1, arrow P'); and

- Air is supplied to the device 7 through the duct 22 and the nozzle 720 (figure 1, arrow A').

The mixture M exits the burner in the form of small air jets i directed upwards, which cause the water E in the pan 4 to boil to a certain extent.

The compressed air and propane streams arriving in the hollow body 70 are mixed therein and the resulting mixed gas is blown into the tube 78 at a relatively high flow rate relative to the small diameter of said tube.

Within the larger diameter end 780 of the tube, the gas flow expands and slows down.

By closing the contactor 610, current is supplied to the spark plug, thereby generating a spark at the tip of the electrode 62, the tip of which is located inside said portion 780, in the center of the combustible mixture.

This causes the mixture to ignite and the burning mixture to propagate inside the conduit 71 and exit therefrom through the downwardly curved portion 710 through which it is directed towards the water surface above the burner 5 .

Since the combustible mixture is also emitted from the burner, the combustion is propagated into the disc.

A monitoring and control circuit, indicated generally at 80 in Figure 5, such as a microprocessor, is provided for monitoring and controlling the device.

The monitoring and control circuits are programmed to ensure that the maneuvers are carried out in the safest state.

As soon as the sensor 8c detects the presence of a flame in the tubular outlet 71, said circuit 80 controls the contactor 610 so that the power supply to the spark plug 6 is turned off.

The circuit closes the valve 18 as long as the sensors 8a, 8b detect the presence of a flame in the pan.

Combustion in conduit 71 then ceases due to the failure of the ignition system.

Training exercises for fighting fires in the pan can begin.

The presence of the catheter 71 above the disc does not hinder the performance of the maneuver in any way.

In order to maintain a constant level in the pan (above the burners) and to equalize excess water (due to the addition of extinguishing medium), an overflow device (not shown) may also preferably be provided.

Conversely, a water top-up can also be added to compensate for water loss due to evaporation.

These two devices can be combined to form a water circulation device with water level control and optionally a filter.

As can be seen from the circuit diagram of Figure 5, circuit 80 receives information from the following devices:

- ultraviolet radiation detectors 8a, 8b, 8c and sensor 8d;

- a detection circuit 9 for detecting abnormal levels of propane or carbon monoxide in the enclosed area L; and

- temperature probe 93 .

The circuit is programmed to control the contactor 610 to control the firing of the electrodes, the solenoid valves 14 and 18 and the fan 92 are all controlled by a predetermined program.

Microprocessor 80 can of course be controlled at will, for example, via a computer keyboard, to input various operational and operational-monitoring parameters into the microprocessor, and to initiate and terminate maneuvers.

During the drill, the trainee must attempt to extinguish the flames arising from the fire using the appropriate type of fire extinguisher available.

The presence of an active flame is continuously detected by the various detectors 8a, 8b. Of course, more than two such detectors can be provided if the manufacturing of the exercise is complicated.

When the detectors can no longer detect the flames, the fire suppression is considered satisfactory, prompting the trainee to go all out.

Sufficient cooling of the fire scene can also lead to flameout, which is detected by sensor 8d, which takes into account real-time temperature measurements.

In both cases above, the circuit will cause the solenoid valve 14 to close, thereby preventing propane from reaching the fire.

Air can continue to arrive, which is not a difficult problem to solve. The air delivered by the blower can also be directed to the outside via the valve 21 .

It will be understood that throughout the operation the electrodes are outside the medium used for extinguishing the fire and are protected by the conduit 71 from moisture and mist due to the water E boiling in the pan 4 .

Thus, the electrodes can still be used for new maneuvers which can be repeated right away in the same way as above.

Preferably, the circuit 80 is programmed so that if the trainee has not extinguished the fire after a certain given time (for example after one minute), the solenoid valve 14 is still activated to cut off the propane supply, thereby automatically extinguishing the fire at the fire site .

If the presence of propane in the enclosed area L is detected by sensor 90 (caused, for example, by a leak or ignition failure), or if an abnormal level of carbon monoxide is detected by sensor 91, then circuit 80 turns on fan 92, which in turn activates solenoid valve 14 Shut down to remove those noxious fumes from the area and cut off the propane supply.

If the temperature is abnormal, which may be caused by a runaway ignition, the temperature sensor 93 will also close the solenoid valve 14, thereby cutting off the propane supply to the burner.

It is of course possible to provide several fire places of the invention in the same area, each fire place being fully or partially fed by the same bottle of propane 1 and/or the same blower 2 .

The number and position of the various sensors 8, 90, 91 and 93 are of course adapted to suit the configuration of the area and the location of the respective fire scene.

As mentioned above, the difficulty of the maneuver can be varied by varying the number and angular position of the flame detectors 8a, 8b.

It will be appreciated that ambient air may be used as the oxidant for ignition if the enclosure 7 is placed away from any hazard. For this purpose, the duct 22 is removed and the air passes through suitably adjusted air inlet vents 76-77 and 76'-77' and then enters the housing 7 through the inlet 76. The entry of compressed gas into the hollow body 72 creates a sufficient negative pressure that air is sucked into it.

The proper ratio of combustible gas and oxidizer air can be adjusted by means of cam plate 75 and, where applicable, by closable vent holes 76-77 and 76'-77'.

The device can be provided in a fixed or mobile area, for example, on a truck of the type described in the above-mentioned document EP-0145 465.
