Description

The proposed utility model relates to technical means of protection, and can be used for physical protection of the perimeters of objects and extended lines of protection on flat and rough terrain.

A known design of a mobile fence based on a block of spirals closest to the claimed technical solution. A spiral block for a mobile fence contains three spirals of the same diameter made of barbed tape reinforced with a wire core, oriented relative to each other in the shape of a triangular prism, with all turns of adjacent spirals pairwise interconnected at points of contact uniformly distributed around the circumference of the coil and located on one straight along the length of the spiral. The unit is equipped with a transport container, consisting of two unlockable metal frames, on which end coils of spirals are rigidly fixed. On the sides of the metal frames there are locks for forming a transport container and fixing the frames having eyes in the lower part for fastening them to the ground and on the end sides for fastening the containers together (patent of the Russian Federation. IPC E04H 17/04, RU 2315159, publ. 01/20/2008).

Signs of an analogue that match the features of the proposed utility model:

1. The presence in the composition of the mobile fence of three spirals of the same diameter of barbed tape reinforced with a wire core, oriented relative to each other in the shape of a triangular prism, with all the turns of adjacent spirals pairwise interconnected at points of contact evenly distributed around the circumference of the coil and located on one straight line along the length of the spiral.

2. Convenient and safe transportation of spiral blocks by any type of transport.

3. The ability to sequentially connect the blocks of spirals to each other, to organize a mobile fence of great length.

4. The ability to install and dismantle in a short time extended barriers for the physical protection of the borders of protection.

The significant disadvantage of this prototype device is the following:

Due to the volumetric structure, significant cutting effect and springing properties, a block of barbed spiral spirals oriented relative to each other in the shape of a triangular prism is a particularly difficult physical obstacle. However, the design of the metal transport container, which is part of the spiral block, when deployed on the ground, creates the conditions for easy overcoming of the obstacle. The frames of the transport container are made of a steel bar with a diameter of 10 mm. In the expanded state, the spiral block has a limited length (10 or 20 meters) and, for organizing an extended security line, the frames of the transport containers of adjacent spiral blocks are interconnected, forming a rigid structure containing two rows of steps from horizontally arranged rods (see Fig. 3), contributing to the easy overcoming of obstacles by means of climbing.

The technical result obtained by the implementation of the utility model is to increase the barrage properties of a mobile fence, reduce the complexity of its manufacture.

The technical result is achieved by the fact that in a spiral block for a mobile fence containing three spirals of the same diameter made of barbed tape reinforced with a wire core, oriented relative to each other in the form of a triangular prism, and all the turns of adjacent spirals are paired together at the points of contact, evenly distributed around the circumference of the coil and located on one straight line along the length of the spiral, the following difference is provided - it is equipped with two metal grids on which the gesture the end coils of the spirals are fixed, and the lattices are made with the ability to fasten them together with brackets and packing tape.

Between the set of essential features of the claimed object and the achieved technical result there is a causal relationship, namely:

1. The spiral block is equipped with two metal grids on which the end turns of the spirals are rigidly fixed. When deploying a mobile fence on the ground, the lattices of adjacent spiral blocks are interconnected with metal brackets, and their bases are attached to the ground with metal crutches. Combined lattices of adjacent spiral blocks do not have rigidity in the longitudinal direction of the barrier, since they are fixed to the ground at the base and balanced in the longitudinal direction of the barrier only by extended spirals of adjacent blocks, do not contain horizontally arranged rods in the longitudinal direction of the barrier, and thus do not create conditions to overcome the obstacle by climbing at the junction of the spiral blocks.

2. In the proposed utility model, the lattices of spiral blocks contain a smaller number of parts compared to the frames of analog containers, and for their manufacture a smaller amount of welding is required, which accordingly reduces the complexity of manufacturing.

The utility model can significantly increase the barrage properties of the fence, as well as reduce the complexity of manufacturing.

The proposed mobile fence consists of individual blocks of spirals, adjacent lattices 13 of which are fastened together using metal brackets, when deployed on the ground.

Interconnected lattices 13 of adjacent blocks of spirals are attached to the ground with crutches 12 (see figure 5).

Structurally, the spiral block consists of spirals 1 and 2 located at the base of the block, and spirals 3 located above them, oriented relative to each other in the shape of a triangular prism (see Fig. 6). The turns of adjacent spirals are pairwise interconnected at their points of contact. The block is equipped with two gratings 13, welded from a bar with a diameter of 10 mm, on which end coils of the spirals 1, 3, 5 are rigidly fixed. For the convenience of transporting the blocks in the folded state, its gratings 13 are fastened together by a packing polyester or steel tape 14 (see Fig. 6) using a combined device for tensioning, bonding and cutting packaging tapes.

The device described above is mounted on the ground in the following way:

The lattice 13 of the first block of spirals is fixed at the beginning of the guard line. The packing tape 14 fastening the lattices of the spiral block is removed. The spiral block is stretched to the required length along the guard site. The second lattice 13 of the spiral block is temporarily fixed using stretch marks or crutches 12. The second spiral block is mounted next to it. Adjacent lattices 13 of both spiral blocks are fastened together with steel brackets and fastened to the ground with crutches 12. It is stretched to the required length along the guard line and the second spiral block is fixed. Similarly, the remaining blocks of spirals are mounted. Dismantling the mobile fence is carried out in the reverse order.
