Problems solved by technology

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 can 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

Embodiment 1

[0022] like Figure 1-6 As shown in the figure, an intelligent device for salvaging lost and discarded nets on the offshore seabed includes a hull 3, and a winch 1 is provided at the tail of the hull 3, and the winch 1 is electrically connected to the control panel 2, and the winch 1 passes through the drag 4. Connect the lifting ring 5, the lower part of the lifting ring 5 is provided with a connecting shaft 6, and the lower part of the connecting shaft 6 is connected with a double-layer hook 12. The device mainly hooks the lost and discarded nets on the seabed through the seabed hook parts with hooks that can roll on the seabed, and then salvage the nets to the ship through the intelligent winch at the tail of the ship. The whole set of equipment is mainly composed of four parts, one is the winch fixed on the working deck at the stern of the ship; the other is the hook of the seabed nets with hooks that can roll on the seabed; the third is the magnetic fishing component that...

Embodiment 2

[0030] The present invention is an intelligent device for salvaging lost and discarded nets on the seabed in the sea. It is used for the salvage of lost nets in the sea. The control panel 2 connected to the winch 1 on the deck of the hull 3 can accept and display the water depth at the same time (provided by the echo sounder) And the depth of the underwater hook (provided by the depth sensor 9 on the connecting shaft 6) data, to adjust the speed of the trolley 4 to release and retract, especially when the release hook part is close to the seabed and the retracted hook part is close to the sea surface Appropriately slow down the speed of the winch 1, and when you release the trolley 4, you can stop loosening when the depth data of the two are close. During the towing process in the water, you can adjust the length of the trolley 4 at any time according to the two data 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 and equipment, and in particular relates to an intelligent device for salvaging lost and discarded nets on the offshore seabed. Background technique [0002] There are a lot of fishing activities in my country's coastal waters, mainly using trawl nets, purse seine nets, nets and other nets for fishing, and marine fishing activities provide people with a large amount of fish and other proteins. However, in the process of operation, due to bad weather, operation errors and other reasons, all or part of the nets will be lost or discarded (a part will sink to the bottom of the sea), making this part of the nets a "ghost net", which will affect the marine ecology and other aspects. Adverse effects, trawl gear lost or discarded 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 life in the net. In the context of ma...
