Abstract

The invention provides a double-arc trawl net plate. The double-arc trawl net plate includes: a first base plate and a second base plate; three connecting rods, the tops and bottoms of the three connecting rods are fixed to the bottom of the first base plate and the bottom of the second base plate respectively. Top: a plurality of first net plate components, the plurality of first net plate components are respectively arranged on the three connecting rods and located between the first base plate and the second base plate. The double-arc trawl net plate provided by the present invention has independent control between the first adjustment assembly and the second adjustment assembly. The first adjustment assembly can synchronously drive the upper second support plate to rotate through the transmission structure, and the limit assembly ensures the transmission The stability of the structure during operation, through the structure with upper and lower double arc-shaped plates, it is convenient to control the overall screen plate, so as to facilitate the control of the overall underwater position of the screen plate, and the distance between the screen plates can be increased according to the needs of use. The effect of using the trawl net is improved, the structure is simple, and the use is convenient.

Description

technical field [0001] The invention relates to the technical field of trawl net panels, in particular to a double-arc trawl net panel. Background technique [0002] When traditional fishing boat trawling operations, two boats are used in parallel to run at full power and the fishing net is opened between the two boats. This method consumes a lot of energy. Therefore, a single trawler appeared. To move forward and open the fishing net, you must use a single trawling board for a boat. Set the single trawling board for a boat at both ends of the trawl and move forward in parallel to achieve the effect of trawling with two boats. The single trawling board for a boat is used to connect fishing boats and nets. During the time, the lateral expansion force generated during the underwater dragging process is used to ensure the effective deployment of the net sleeve and the net mouth, so as to achieve the effect of fishing. Therefore, the performance of the marine trawl net plate wil...
