A support structure for a trawl jib

Abstract

The invention provides a supporting structure for a trawl net boom and belongs to the technical field of ships. The supporting structure comprises a frame body, wherein a supporting structure body isarranged at the free end of the frame body and comprises a supporting box and a floating body; the supporting box is arranged at the top of the trawl net boom; a storage battery is arranged in the supporting box; a hydraulic lifting platform is arranged on the lower side surface of the supporting box; a lifting plate is arranged at the lower end of the hydraulic lifting platform; piston cylindersare respectively arranged at the periphery of the upper side surface of the floating body; each piston cylinder comprises a cylinder body and a piston rod; the bottom of each cylinder body is hinged to the upper side surface of the floating body; a piston is arranged at the lower end of each piston rod and is arranged in the corresponding cylinder body in a sliding manner; the upper end of each piston rod is hinged to the lower side surface of a lifting plate; when the floating body vertically swings, each piston has at least one position, so that the hydraulic lifting platform is kept relatively stable. The supporting structure provided by the invention realizes a better supporting effect on the trawl net boom, can utilize wave energy for generating power, and is green and environmentallyfriendly.

Description

technical field The invention belongs to the technical field of ships and relates to a support structure, in particular to a support structure for a trawl arm frame. Background technique In reality, due to the small tonnage of fishing boats, they are greatly affected by wind and waves when fishing in the ocean. Especially for boom-type fishing boats, since the trawling jib set on the hull structure is generally long, during trawling operations, the jib In a horizontal state, the free end of the jib protrudes a lot out of the hull structure and is dragged by the fishing net. Since one end of the jib is hinged on the hull structure and there is no supporting structure at the free end, the outer end of the jib is easily stressed and It was damaged and even caused the fishing boat to roll over, endangering the lives of the crew. Contents of the invention The purpose of the present invention is to solve the above-mentioned problems in the existing technology, and proposes a s...
