Description

The utility model relates to obstruction means for protecting water areas from unauthorized entry of small-sized water and underwater boats of small displacement for swimmers, etc.

The closest technical solution adopted for the prototype is the engineering and obstacle obstruction of the reservoir’s alignment described in RF patent No. 171685, including at least two modules containing two rigidly connected booms in parallel, a pedestrian walkway deck equipped with a guard, racks for mounting on surface barriers, a bottom-mounted underwater boom in the form of a network, while the modules are connected in series with each other using detachable movable connectors, the surface boom is made of n several levels of reinforced barbed tape located at a height, several levels of an anti-ram cable are additionally fixed on racks for attaching a surface barrage, an underwater barrage network is made in the form of a section of a steel network fixed to each module with ring cells of wire weaving, the lower part of which is equipped with anti-lifting loads; sections of the steel network of neighboring modules are interconnected using a steel cable passed through adjacent cells of the network.

The general essential features of the prototype, which coincide with the essential features of the proposed technical solution, are as follows - a boom fence, comprising at least two modules containing two parallel-connected booms, a pedestrian walkway deck equipped with a guard, racks for attaching a surface fence to them, fixed bottom is an underwater obstacle in the form of a network, while the modules are connected in series with each other using detachable movable connectors, a surface obstacle made of several levels of reinforced barbed tape located at a height, several levels of an anti-ram cable are additionally fixed on racks for attaching a surface barrier, the lower part of the network of an underwater barrier is equipped with anti-lifting loads.

This net fence - the prototype has high barrage properties, however, it can be overcome with the help of a high-power metal-cutting tool by biting through the cables of an underwater network or barbed wire, which may not be detected even with surveillance equipment.

The technical problem, the solution of which is provided by using the proposed design, is the possibility of unauthorized overcoming of the boom net.

To solve this technical problem, a boom net barrier comprising at least two modules containing two rigidly connected booms in parallel, a pedestrian walkway floor (dress paths) equipped with a guard, racks for attaching a surface guard to them, an underwater guard fixed in the form of a net while the modules are connected in series with each other using detachable movable connectors (mooring devices), the surface obstacle is made of several levels of arm located at a height of barbed tape, several levels of an anti-ram cable are additionally fixed on racks for attaching a surface barrier, the lower part of the underwater barrier network is equipped with anti-lifting loads (weights that prevent the swimmer from lifting the network manually), unlike the prototype, the underwater barrier network is made of cables of the breakaway detection means principle of operation, the surface obstacle contains several levels of cables of the alarm means for detecting the discontinuous principle of deis Twia.

Additionally, to prevent attempts to overcome the obstacle and impact on violators when attempting to overcome, the obstacle can be equipped with non-lethal means fixed on it, for example, hydroacoustic and (or) pyrotechnic and (or) electroshock.

Due to the presence of these distinguishing features, the following technical result is achieved - an alarm is provided to overcome the obstacle or attempt to overcome. In addition, non-lethal effects can be exerted on violators, preventing further attempts to enter the protected area, as well as restricting the violator’s maneuver.

The proposed technical solution can be used on water bodies of various types - canals, rivers, reservoirs, seas, etc. for fencing water intake, spillway channels, river sections in transit protected areas, bridge supports, hydroelectric power stations and other hydraulic structures, floating structures, ships in the parking lot, etc. to prevent unauthorized entry of swimmers, passage of small displacement vessels, including underwater, the proposed design is illustrated in FIG. 1 and 2.

In FIG. 1 shows a module of a booster network alarm fence in basic equipment (without non-lethal means).

In FIG. Figure 2 shows a module of a booster network signal boom in maximum equipment with non-lethal means.

In FIG. 1 and 2 are indicated:

1 - bon;

2 - flooring of a pedestrian passage with a fence;

3 - racks for mounting surface barriers;

4 - reinforced barbed tape (AKL);

5 - anti-ram cable;

6 - a barrier network of cables alarm means detecting a discontinuous principle of operation;

7 - I-beams of anti-lifting loads;

8 - steel fixing loops;

9 - steel fixing cables

10 - shock absorbers in the form of car tires;

11 - surface cables of the alarm means for detecting a discontinuous principle of operation;

12 - pyrotechnic non-lethal effect;

13 - sonar non-lethal effect. Depicted in FIG. 1 and 2, the module of the bare-water engineering and technical fence of the reservoir’s target includes two parallel rigidly connected booms 1, a pedestrian walkway floor with a guard 2, and racks 3 for fastening a surface-mounted fence made of several barbed tape 4 located at a height that is protected from anti-ram cables 5 and cables of the signaling means for detecting the discontinuous principle of action 11; a submarine fence fixed at the bottom in the form of a network 6 made of cables of an alarm means for detecting a discontinuous principle of operation (cells of a network 6 can be formed, for example, by fixing with clamps the intersections of mutually perpendicular cables); the lower part of the underwater boom net is provided with anti-lifting weights 7. The net 6 is fixed to the fastening loops 8 of the booms 1 and the weights 7 using the fastening cables 9. The networks 6 of adjacent sections can be interconnected, for example, using the same ropes 9.

Additionally, to prevent attempts to overcome the obstacle and impact on violators when overcoming it, the obstacle can be equipped with a non-lethal means fixed on it, for example, hydroacoustic 13, and (or) pyrotechnic 12, and (or) electroshock (not shown in the figures).

The underwater signaling network 6, woven, for example, from a cable with a double steel braid, looks like a network woven from a simple steel cable, which eliminates the presence of reconnaissance signs of signaling weapons. When snacking or breaking the network 6, an alarm occurs at the receiving equipment of the operator’s workplace. Above-water signaling armament is made in the form of a breakaway means, triggered by the breakage of the cable sensing element 11, mounted on the surface safety barrier and can be combined with a non-lethal electroshock system.

When a non-lethal impact hydroacoustic means 13 is included in the product, the hydroacoustic waves emitter is located on a separate small pontoon moored from the inside of the booster network signaling barrier and when a signal is received from the underwater signaling network 6 about attempts to overcome, the means is switched on in the exposure mode. In addition, the sonar 13 can also work in acoustic warning mode for underwater swimmers.

When pyrotechnic means of non-lethal influence 12 are included in the product, the starting devices themselves are located directly on the pontoon sections of the booster network and when a signal from the underwater signaling network 6 about attempts to overcome, pyrotechnic devices are shot into the water with their subsequent actuation under water and impact on the underwater intruder .

Non-lethal means can work both in automatic mode upon receipt of a signal from the detection means, and in manual mode according to the operator’s signal.

The use of a bi-net signaling fence in a protected area of the water will increase the level of anti-terrorist protection of the facility.
