Fishing device for fishing net in ocean

Abstract

The invention belongs to the field of ocean fishing, and particularly relates to a fishing device for a fishing net in the ocean. The fishing device comprises outer cylinders, waterproof caps are in threaded connection with the outer cylinders, and contraction spring grooves with openings facing the outer cylinders are formed in the waterproof caps; connecting plates are hung on the sides, away from the outer cylinders, of the waterproof caps, and a plurality of outer cylinders and waterproof caps are uniformly hung on the connecting plates; cutting mechanisms used for cutting off aquatic plants are arranged in the outer cylinders, and power distribution mechanisms used for supplying power are arranged on the sides, close to the waterproof caps, in the outer cylinders; two fishing mechanisms are symmetrically arranged in the power distribution mechanisms relative to the outer cylinders, and protection mechanisms used for safety are further arranged in the outer cylinders. If the fishing net is wound on the aquatic plants or corals or pressed by heavy objects, torsional springs contract to wind steel cables on winding wheels, so that fishing hooks shake the fishing net, the corals, the aquatic plants or the heavy objects on the fishing net are shaken off, the fishing net or the aquatic plants are cut off through a cutting knife, and the situation that the aquatic plants are pulled up with roots due to excessive force, and the ecological environment of the ocean is damaged is prevented.

Description

technical field [0001] The invention belongs to the field of marine fishing, in particular to a fishing net fishing device in the ocean. Background technique [0002] Marine debris refers to persistent, man-made or processed solid waste in the ocean and coastal environment. Some of these marine debris stay on the beach, and some can float on the sea surface or sink to the bottom of the sea. The largest plastic garbage in the ocean is Abandoned fishing nets, some miles long, are called "ghost nets" by fishermen. Under the action of ocean currents, these nets are twisted together and become "death traps" for marine mammals. Plastic waste can also threaten navigation Safety. Abandoned fishing nets can entangle the propellers of ships, and they can damage the hull and machinery, causing accidents and downtime. Existing equipment for salvaging abandoned fishing nets usually uproots the aquatic plants entangled in fishing nets, destroying the ecology of the ocean. Contents of t...
