Description
FIRE EXTINGUISHING BUCKET AND CONTROE SYSTEM DESIGNED FOR HEEICOPTERS
Technical Field of the Invention
The present invention relates to a fire extinguishing bucket designed for fire extinguishing helicopters, which takes the water required for extinguishing the fire in helicopters used in firefighting, from places such as sea, lake, river, stream, water basin, etc., and keeps it during transport to the area where the fire is located, and when the fire is reached to the place where the fire will be extinguished, discharges the water therein, and the control mechanism by which the fire extinguishing bucket is controlled.
Prior art and technical problems encountered:
In the current state of the art, one of the most widely used vehicles in the field of fire extinguishing, together with firefighting aircraft, is firefighting helicopters due to their mobility. Firefighting helicopters have a fire extinguishing bucket at the bottom. Firefighting helicopters descend to fill the bucket under the fuselage with water from places such as sea, lake, river and water basin, after filling the water, they take off and carry the bucket full of water to the place where the fire will be extinguished, and when they arrive at the fire scene, they discharge the water in the bucket on the fire with the mechanism it has. This process is repeated many times until the fire is extinguished.
There are special hooks in the lower fuselage of helicopters designed to carry loads under the fuselage. These hooks are connected with apparatus such as buckets, chains, steel ropes, polyester slings, etc. specially designed for carrying water in firefighting.
In the current state of the art, crowns made of aluminum casting are used in fire extinguishing buckets. The connection holes on this crown wear out and break over time depending on use. Over time, it loses its original physical appearance and becomes unable to function as it bends and twists.
There are no parts to protect the main body at the load lifting connection points in the fire extinguishing bucket mechanism in existing firefighting helicopters. Since the load connection points wear out over time due to the absence of these protective parts, these parts need to be replaced.
Firefighting helicopters have a power socket that provides electrical power to the water carrying bucket and system used in firefighting. In some cases, these power sockets must be separated during fire extinguishing. The water carrying bucket used in an emergency has to be thrown from the helicopter. However, in the state of the art, since these sockets cannot be separated easily and quickly when desired, they may damage the helicopter.
In the state of the art, strips are used to form the main frame of fire extinguishing buckets and to increase the strength of the bucket. However, over time, these strips may break and lose their properties.
In the state of the art, fire extinguishing buckets are located approximately 25 meters below the helicopters. Especially during night flights, the bucket cannot be seen from above, so it is not possible to understand how much water it contains, and it is not possible to be sure whether enough water is carried to the fire location to extinguish the fire. Since the operator cannot see the condition of the bucket at night, problems arise in terms of flight safety.
In addition, in the state of the art, since the main rope carrying the fire bucket is long, the bucket rotates under the weight and in weightless positions and may break the power cable.
In addition, in the state of the art, there is no warning system as to whether the mechanism that releases, collects and locks the quick discharge valve is working or not. Since this warning system is not available, the operator cannot use the system effectively and in a controlled manner.
In addition, the materials used in the interior parts of the load carrying and quick discharge valve locking mechanism are structurally weak and corrode very quickly. The mainspring system to which the mechanism that releases, collects and locks the quick discharge valve within the load carrying and quick discharge valve locking mechanism is connected, corrodes and fails due to salt water. For this reason, the system becomes unusable after a while.
In addition, there is a button in the system control box only to discharge the water. In case of an electrical malfunction, the mission will be cancelled because the water in the bucket cannot be emptied, and in case of an emergency that may occur in the helicopter, the water bucket and control system will be completely removed from the helicopter since the water cannot be emptied. This will cause financial damages and loss of duty. There is no manual water discharge system.
In addition, there is no mechanism that counts and records the number of water pulses made by the helicopter.
Object of the Invention
The object of our present invention is to eliminate all technical problems of the prior art mentioned above. In order to eliminate these problems, our invention, the fire extinguishing bucket and control system designed for helicopters, was developed. Thus, faster technical support, spare parts and ease of maintenance can be provided for malfunctions.
Brief Summary of Our Invention
In order to eliminate the above-mentioned technical problems in our invention, the bucket body was formed by cutting PVC polyester tarpaulin into the required dimensions and shapes and joining them together with sewing, heat bonding, ultrasonic bonding and special adhesives. This body structure serves to store the water needed for fire extinguishing and provides water tightness and durability.
In our invention, special guide slots were created vertically on the outside of the bucket. These guide slots are manufactured using body material. It houses the main carrier polyester columns (slings), which are joined by stitching on the body. Special guides are then joined to the main body by sewing, heat bonding, ultrasonic bonding and special adhesives. Main carrier polyester columns connect the bucket to the load carrying and quick discharge valve locking mechanism.
After joining the main carrier polyester columns to the main body, specially shaped strip- shaped pieces made of spring steel are attached vertically to the slots at the bottom of these guides in order to increase strength and support various connections. At the bottom of the bucket, there are mounting locations for the quick discharge valve, various connection parts on the base and side surfaces, and tipping weights.
The quick discharge valve of our present invention consists of PVC polyester tarpaulin, fabric, water leakage prevention gasket, and wick and uppcr/lowcr connection points. The base is wide, tapered upwards or shaped flat, tubular, hollow at both ends, manufactured by sewing, heat bonding, ultrasonic bonding and joining with special adhesives.
Our load carrying and quick discharge valve ensures that the water stored in the bucket stays in the bucket and the water is discharged when needed. The quick discharge valve is fixed to the bottom of the bucket by applying liquid gasket and fixed with bolts and nuts. There are holes at the top for the carrying ropes to pass through, the ropes are threaded through these holes in a certain order, knotted and
all the ropes are gathered taut in a ring at the top. This ring is connected to the load carrying and fast unloading valve locking mechanism with fasteners such as steel rope, eyebolt, chain etc. There is adjustment of ropes and fasteners to prevent water leakage.
When the water discharge button in the control box is pressed by the operator and pilot, the load carrying and quick discharge valve releases the steel rope locked in the mechanism in the locking mechanism. With the release of the steel rope, the water in the bucket moves with the force of gravity by opening the rapid discharge valve towards the outside of the bucket. Meanwhile, the water is discharged and the quick discharge valve remains outside the bucket. The release and retracting mechanism within the load carrying and quick discharge valve locking mechanism retracts and locks the released steel rope. Thus, the quick discharge valve, which is connected to the steel rope with rope and fasteners, returns to its previous position in the bucket and is locked, becoming ready for the next task.
In the bucket that is the subject of our invention, a tipping weight is used. This tipping weight is made of steel or lead material. The water bucket attached to the helicopter must easily dive into the water in the water source. Thanks to the tipping weights used in our invention, by making one side of the bucket heavier, it is ensured that the bucket lies on its side, so that the bucket is filled more quickly and it is easier to take water from shallow places.
Our fire extinguishing bucket, which is the subject of our invention, contains guide arms and connection apparatus. These connecting arms and connecting apparatus are made of aluminum by CNC and lathe machining. The function of the guide arms and connection apparatus is to prevent the bucket from being torn or deformed by the force of water, to keep it open and to ensure that it folds during transportation. Guide arms and connection apparatus are positioned at the upper center of the bucket. It consists of guide arms and connection apparatus, a hole in the middle, a material called crown, and a plurality of arms. The arms are connected to the
material called the crown and to their places on the bucket using bolts, nuts and pins so that they can be moved. The crown is connected from the bottom and top to a place close to the bucket floor and to the load carrying and quick discharge valve locking mechanism by adjusting with a steel rope. The reason for this is to keep the guide arms and connection apparatus in the desired position.
Our fire extinguishing bucket, which is the subject of our invention, contains a polyester column passed through special slots to surround the bucket 360 degrees. There are capacity connection points on this column and it helps to adjust the water capacity that the bucket will carry. The amount of water to be taken by tightening and loosening is determined according to the carrying capacity of the helicopters.
Our fire extinguishing bucket, which is the subject of our invention, includes a load carrying and quick discharge valve locking mechanism. Our load carrying and quick discharge valve locking mechanism is machined from aluminum material by CNC and lathe, has a power cable entry section and resembles a triangle shape. There are two connection points at the lower corners of the triangle to connect the bucket. There is a connection point at the top of the triangle to connect the entire system to the helicopter. It also incorporates a mechanism that allows the steel rope connected to the quick discharge valve to be released and retracted and locked.
All bolts, nuts, washers, steel ropes, polyester slings, polyester columns, eyebolts, quick-detachable materials, rivets, electrical sockets, chains, locking elements, etc. used to provide integrity in the fire extinguishing system subject to our invention and to carry loads are used as fasteners.
In the fire extinguishing system subject to our invention, electrical cables are used for electrical and signal transfer between the control box and the helicopter fuselage electricity, between the control box and the pilot, between the control box and the operator, between the control box and the load carrying and quick discharge valve locking mechanism, between the control box and the external power supply.
In the fire extinguishing system subject to our invention, there is a control panel consisting of a box with power inputs and outputs, which regulates the electrical connection of the entire system and contains buttons, fuses, warning lamps, pulse counters and switches that allow us to control the system.
In the fire extinguishing system subject to our invention, there is a main carrier between the main body and the helicopter. The load carrying and quick discharge valve locking mechanism is located between the main body and the helicopter.lt carries fire extinguishing buckets and control systems designed for helicopters in the fight against fire extinguishing. It is connected to the system and helicopter with fasteners and guides the manual discharge and power cable.

Pulse counter (74) that counts every time the automatic water discharge button (72) is pressed,
Rope release and retracting mechanism warning (75) showing the rope release and retracting mechanism that allows the water in the bucket to be discharged to the fire,
Carrying handle (76) for carrying the control panel
Power output fuse (77) activated in case of overcurrent
Main switch (78) for turning the system on and off
System power input (79), which allows energy input that feeds the entire system
Main body power input (80) that receives electricity from the helicopter and transfers it to the control panel
Water discharge control output controlled by the helicopter user (81).
In the fire extinguishing system subject to our invention, there is a main carrier between the main body and the helicopter. The load carrying and quick discharge valve locking mechanism is located between the main body and the helicopter. It carries fire extinguishing buckets and control systems designed for helicopters in the fight against fire extinguishing. It is connected to the system and helicopter with fasteners and guides the manual discharge and power cable. Between the main body and the helicopter, our main carrier includes the following; an air carrier connection element (84), one manual discharge rope (85), connector connected power cable (86) that provides energy to the system power input, quick detachable connector (87) from the power cable (86) with connector connection energizing the system power input, in case of emergency, when the fire extinguishing system has to be completely removed from the helicopter, main power cable and main carrier connection element (88), which provides power and signal communication from the control panel to our load carrying and quick discharge valve locking mechanism of our bucket, locking mechanism of the load carrying and quick discharge valve of our bucket, power and signal connection connector (89), connection element (90) connecting the load carrying and quick unloading valve locking mechanism of the bucket to the main carrier (82).
The fire extinguishing bucket fire extinguishing device designed for fire extinguishing helicopters of our present invention is as follows:
The fire extinguishing helicopter connects the body power or an equivalent power supply to the body power input (80), thus providing power to our control panel. When electrical power comes on, our pulse counter is activated. The main switch (78) is turned to the open position. Our fire mechanism is ready to work. Our fire extinguishing helicopter comes to the fire area after taking water in the bucket, when the operator or pilot presses the automatic water discharge button (72), the push pull solenoid (33) is energized and pulls the shaft in the center, pulls the push pull rods and releases the locking jaw (55). The locking rod (67) is released. The water discharge valve (18) moves towards the bottom of the bucket with the weight of the water and opens. The water in the bucket drains into the fire area. Then, the quick discharge valve (18) is retracted by installing the mainspring (70) located within the rope release and retracting mechanism (54). The sensor (64) detects the movement of the rope release and retracting mechanism (54) and turns on the rope release and retracting mechanism warning on the control panel (75). If the water in the bucket is not discharged to the fire area in case of any electrical failure, the operator pulls the manual discharge apparatus (83) and discharges the water in the bucket. This prevents the fire extinguishing helicopter from experiencing an emergency. Thanks to its manual discharge mechanism, the fire extinguishing helicopter continues its duty all day long without the need for electricity.
If the fire extinguishing task is to be carried out under night conditions, night illumination is provided by switching the lamp on/off switch on the control panel (71) so that the operator can see the fire extinguishing bucket.
Every time the operator or pilot presses the automatic water discharge button (72), the pulse counter (74) starts counting as water will be discharged.
