Abstract

The invention provides an airfoil-shaped trawl net panel. The airfoil shape trawl net board includes an airfoil net board, an active deceleration mechanism, a limit mechanism, a transmission mechanism, a level adjustment mechanism, and a depth adjustment mechanism, and the airfoil net board includes two curved side boards, a top board and a bottom board , the two curved side plates are symmetrically arranged, and the top plate and the bottom plate are respectively welded to the upper end and the lower end of the two curved side plates, the active deceleration mechanism is fixedly connected in the airfoil net plate, and the active deceleration mechanism The mechanism includes an arc-shaped water baffle, a sliding rod, a box body, a fixed plate, a spring, a groove and a resistance plate. One end of the sliding rod penetrates through the airfoil mesh plate and is fixedly connected with the arc water baffle, and the box body is fixedly connected between the two curved side plates. The airfoil-shaped trawl net plate provided by the invention has the advantages of high stability, increased fishing capacity of fishing boats and reduced energy consumption.

Description

technical field [0001] The invention relates to the technical field of trawl net plates, in particular to an airfoil-shaped trawl net plate. Background technique [0002] Due to the increasing cost of operating commercial trawlers, it is important to improve the efficiency of fishing equipment in order to minimize drag and fuel consumption requirements. A common problem with the use of conventional trawl panels to spread the mouth of the trawl is inefficiency. Traditional stencils are now fished at an angle of attack of roughly 20-40 degrees. There is a need to provide more efficient trawl panels, especially trawl panels with better spread of the trawl and reduced drag during actual trawl operations. [0003] Furthermore, with conventional trawl screens, vortices are formed behind the trawl screens, which push the screens towards each other. During operation, the screens must be constantly pushed outwards to increase the space between the screens, which requires additiona...
