Embodiment 1

[0022] Such as Figure 1-6 As shown, an intelligent device for salvaging lost and discarded net gear on the seabed includes a hull 3. A winch 1 is provided at the tail of the hull 3. The winch 1 is electrically connected to the control panel 2. The winch 1 passes through the dragging net. 4. Connect the suspension ring 5, the suspension ring 5 is provided with a connecting shaft 6 below, and the double-layer hook 12 is connected below the connecting shaft 6. The device mainly hooks the lost and discarded nets on the seabed through the seabed hooking part that can roll on the seabed and has a hook, and then salvages the nets to the ship through the intelligent winching machine located at the tail of the ship. The whole device is mainly composed of four parts, one is the winch machine fixed on the operation deck at the stern of the ship; the other is the subsea net gear hook that can roll on the seabed and has a hook; the third is the magnetic fishing component that can effectiv...

Embodiment 2

[0030] The present invention is an intelligent device for salvaging lost and discarded net gear on the seabed, which is used for salvaging lost net gear in the sea. The control panel 2 connected to the winching machine 1 on the deck of the hull 3 can simultaneously receive and display the water depth (provided by the depth sounder) and the depth of the underwater hook (provided by the depth sensor 9 on the connecting shaft 6) to adjust the speed of the dragging 4 to release and retract, especially when the loose hook is close to the bottom of the sea and the hook is close to the sea. Appropriately slow down the speed of the winch machine 1, and when releasing the drag line 4, you can stop loosening when the depth data of the two are close. During the dragging process in the water, the length of the drag line 4 can be adjusted at any time according to the data of the two to ensure that the roller 8 is just on the seabed scroll.

Abstract

The invention relates to an intelligent device for salvaging fishing nets lost and discarded in an offshore seabed, and belongs to the technical field of fishing gear equipment. The intelligent deviceincludes a hull, a winch is arranged at the tail of the hull, the winch is electrically connected with a control panel, the winch is connected with a hoisting ring by a tow rope, a connecting shaft is arranged on the lower part of the hoisting ring, and a double-layer hook is connected with the lower part of the connecting shaft. According to the intelligent device for salvaging the fishing netslost and discarded in the offshore seabed, the fishing nets are prevented from sinking to the seabed for a long time and resulting in the death of a large number of marine life, the marine ecologicalenvironment can be effectively protected, and metal garbage of the seabed can further be salvaged ashore.

Description

technical field [0001] The invention belongs to the technical field of fishing gear equipment, and in particular relates to an intelligent device for fishing lost and discarded net gear on the sea bottom. Background technique [0002] There are a large number of fishing activities in my country's coastal waters, mainly using trawling nets, purse seines, stretch nets and other nets for fishing. Marine fishing activities provide people with a large amount of fish and other proteins. However, during the operation, all or part of the nets will be lost or discarded due to bad weather, operational errors, etc. Adverse effects, lost and discarded trawling gear in seawater will cause a large number of marine organisms to accumulate in the net, resulting in the death of a large number of marine organisms in the net. In the context of marine ecological civilization, to reduce the adverse effects of lost and discarded nets on the economy and marine ecology, it is necessary to promptly...
