Description

The utility model relates to the means of engineering weapons, and more specifically to the means of overcoming mine-explosive obstacles in coastal sea zones and can be used to make passages in an explosive manner.

The invention is known - an extended demining charge UZP-06 (http://www.aoniii.ru) (installation of remote demining UR-07), consisting of sections of demining charges connected in a thread, a detonation transmission unit, a brake rope, a delayed action fuse and connecting cable. The disadvantage of the UZP-06 is that after being detonated in a mined area, it forms a rather narrow passage for the passage of amphibious vehicles. When re-laying UZP-06 to widen the passage, there is a high probability of the formation of non-mined areas.

A known prototype is a flexible array delivery device (US 5417139, IPC F41H 11/12), consisting of a rocket launch tube, a rocket with rotary telescopic arms and a mesh demining charge attached to them (consists of demining charge sections connected to a network), packed in a container ... When the rocket is fired from the launch tube, the arms spread apart and pull the net attached to them along the guide cables (one at each end of the arm), which allows the mesh charge to be deployed from the container and delivered to the deployment site. The disadvantage of such a device is that the telescopic arms are limited in length, which leads to a limitation of the area of the mesh charge, and hence to a decrease in the width of the passage.

The problem to be solved by the claimed technical solution is to increase the demining effect of the marine mesh demining charge (increasing the width of the passage).

This task is achieved due to the fact that the marine mesh demining charge, including the demining charge section and the container, in contrast to the prototype, is delivered to the place of deployment not by a rocket, but by an unmanned floating or flying vehicle after preliminary extraction by a float-type lifting device from the container lowered to the bottom in the demining area. This design allows the container to be loaded with a larger mesh charge and to make large passages.

The technical result of the utility model is to increase the demining effect of the marine mesh demining charge.

FIG. 1 (front view) and FIG. 2 (left-hand sectional view) shows: sections of a mesh demining charge 1, container 2, a float-type lifting device 3 in a firing position. FIG. 3 (left-hand sectional view) shows the section of the demining mesh charge 1, container 2, float-type lifting device 3 before the container lid is thrown off. FIG. 4 shows the towing of a mesh charge by an unmanned floating vehicle with subsequent laying.

A demining net charge is a network of sections of cylindrical demining charges of a certain length or sections of two spherical charges connected by a thread of a certain length (so that the spherical charges are in the nodes of the net charge) 1. Four sections of demining charges (of the first or second type), connected between themselves, form a cell of the network. The float-type lifting device 3 is a float that floats up after throwing off the container lid and pulls the edge of the net to the water surface. The edge of the net delivered by the float-type lifting device to the surface of the water is taken in tow by an unmanned floating or flying vehicle and pulled until the net is fully opened. One of the demining charge sections (located on the towed edge of the net) contains a fuse to cause its detonation, causing the subsequent detonation of the entire net.

The application of a marine mesh demining charge can be shown in the following example.

In a mined coastal sea area, the marine demining net charge is delivered in container 2, which is stacked on the bottom. If the container with a marine mesh demining charge is set up in an area of sufficiently deep water (approximately 3-10 m), then the marine mesh demining charge, after the container lid is thrown off by a separating mechanism, is removed from the container by a float-type lifting device 3 and towed towards the water's edge by an unmanned floating or flying vehicle for the purpose of full deployment, stowage and detonation. If a container with a marine mesh demining charge is deployed in shallow water (up to 3 m), then the marine mesh demining charge is manually removed and towed towards deep water by an unmanned floating or flying vehicle for the purpose of full deployment, laying and detonation.

The use of the utility model increases the demining effect of the sea net charge of demining by increasing the area of the net charge.

Claims (1)

The marine demining net charge consists of demining charge sections connected by a thread in such a way that four demining charge sections form a net cell, floats located at the net edge with the possibility of raising the net edge to the water surface for further full net opening and towing by an unmanned floating or flying vehicle to the place of setting, while one of the sections of demining charges, located on the towed edge of the net, contains a fuse to cause its detonation, causing the subsequent detonation of the entire net.
