A mine-retrieving device for marine operations

Abstract

This invention discloses a torpedo retrieval device for sea use, which is equipped with a retrieval net frame assembly and a retrieval net (1). When a torpedo retrieval operation is required, a speedboat is driven into the torpedo placement area. When the retrieval net frame assembly and the retrieval net 1 are thrown onto the torpedo by the pull rope 7, the top of the retrieval net 1 covers the top of the torpedo. The retrieval net frame assembly sinks under the action of gravity, so that the retrieval net 1 is pulled out from the interlayer as the retrieval net frame assembly gradually sinks. When the retrieval net frame assembly sinks to the bottom of the torpedo, the retrieval net 1 is completely wrapped around the torpedo. The pull rope is pulled to drag the torpedo onto the speedboat.

Description

Technical Field

[0001] This invention relates to a device for mine recovery at sea. Background Technology

[0002] Currently, the common method for retrieving torpedoes that have sunk into the sea is to simply wrap a net around the torpedo and then retrieve it. However, when the net is cast onto the sea surface, it floats because of its light weight and cannot be wrapped around the part of the torpedo that is below the surface. It is necessary to manually dive to the seabed to wrap the net around the torpedo to complete the retrieval work, which is very inconvenient and wastes manpower. Summary of the Invention

[0003] This invention provides a torpedo retrieval device for marine operations. It can directly cover the torpedo with a retrieval net, eliminating the need for manual placement of the net. This device is convenient to use, saves manpower, and allows for remote torpedo retrieval operations without personnel being near the torpedo, thus improving operational safety.

[0004] This invention adopts the following technical solution: a mine-retrieving device for marine applications, comprising a net frame assembly and a net. The net frame assembly includes an outer net frame and an inner net frame. The outer net frame is circular, and the inner net frame is also circular. The diameter of the outer net frame is larger than that of the inner net frame. The inner net frame is placed inside the outer net frame and is concentrically positioned with it. A sandwich layer is provided between the outer and inner net frames. The upper part of the sandwich layer is open, and the bottom of the sandwich layer has a connecting ring. The connecting ring securely connects the inner and outer net frames together and closes the bottom of the sandwich layer. The bottom is connected to the bottom of the interlayer. The net is placed inside the interlayer from bottom to top, and the top of the net is located outside the interlayer. A pull rope is connected to the side of the outer net frame. One end of the pull rope is fixedly connected to the outer net frame. When the net frame assembly and the net are thrown onto the torpedo by the pull rope, the top of the net covers the top of the torpedo. The net frame assembly sinks under the action of gravity, so that the net is pulled out of the interlayer as the net frame assembly sinks. When the net frame assembly sinks to the bottom of the torpedo, the entire net is wrapped around the torpedo. Pulling the pull rope will drag the torpedo onto the ship.

[0005] The inner mesh frame is made of stainless steel. The outer mesh frame is made of stainless steel.

[0006] The shape of the connecting ring corresponds to the shape of the bottom of the interlayer.

[0007] Before use, the top of the interlayer is provided with several limiting plugs. These limiting plugs are used to block the net inside the interlayer. When it is necessary to throw the net into the sea to retrieve a torpedo, the limiting plugs are removed.

[0008] The fishing net is made of nylon.

[0009] The present invention has the following beneficial effects: After adopting the above technical solution, the present invention can directly throw the net frame assembly and the net onto the torpedo, and use the gravity of the net frame assembly to sink and cover the torpedo. In this way, there is no need for personnel to dive underwater to cover the torpedo with the net, which not only saves manpower and resources, but also makes the operation convenient and allows for rapid torpedo retrieval operations, greatly improving the efficiency of the operation. The construction personnel can operate on the shore or on the boat without diving, which also greatly improves the safety of the operation. Attached Figure Description

[0013] exist Figure 1 , Figure 2 and Figure 3 This invention provides a mine-retrieving device for marine applications, comprising a net frame assembly and a net 1. The net frame assembly includes an outer net frame 2 and an inner net frame 3. The outer net frame 2 is circular, and the inner net frame 3 is also circular. The diameter of the outer net frame 2 is larger than the diameter of the inner net frame 3. The inner net frame 3 is placed inside the outer net frame 2 and is concentrically positioned with it. A sandwich layer 4 is provided between the outer net frame 2 and the inner net frame 3. The upper part of the sandwich layer 4 is open 5, and the bottom of the sandwich layer 4 is provided with a connecting ring 6. The connecting ring 6 fixes the inner net frame 3 and the outer net frame 2 together and closes the bottom of the sandwich layer 4. The bottom of the net 1 is connected to the bottom of the sandwich layer 4. The net 1 is placed inside the sandwich layer 4 from bottom to top, with the top of the net 1 located outside the sandwich layer 4. A pull rope 7 is connected to the side of the outer net frame 2. One end of the rope 7 is fixedly connected to the outer net frame 2. When the net frame assembly and net 1 are thrown onto the torpedo by pulling the rope 7, the top of the net 1 covers the top of the torpedo. The net frame assembly sinks under the action of gravity, so that the net 1 is pulled out from the interlayer as the net frame assembly gradually sinks. When the net frame assembly sinks to the bottom of the torpedo, the net 1 is completely wrapped around the torpedo. Pulling the rope will drag the torpedo onto the ship. The inner net frame 3 is made of stainless steel, and the outer net frame 2 is made of stainless steel. The shape of the connecting ring 6 corresponds to the shape of the bottom of the interlayer 4. Before use, the top of the interlayer is provided with several limiting plugs 8, which block the net in the interlayer. When it is necessary to throw it into the sea to retrieve the torpedo, the limiting plugs 8 are removed. The net 1 is made of nylon.

[0014] The method of using this invention is as follows: When torpedo retrieval operations are required, a speedboat is driven into the torpedo placement area. When the net frame assembly and net 1 are thrown onto the torpedo by the pull rope 7, the top of the net 1 covers the top of the torpedo. The net frame assembly sinks under the action of gravity, so that the net 1 is pulled out from the interlayer as the net frame assembly gradually sinks. When the net frame assembly sinks to the bottom of the torpedo, the net 1 is completely wrapped around the torpedo. The pull rope is then pulled to drag the torpedo onto the speedboat.
