Problems solved by technology

[0004] However, the structure of this open-hole type dragging plate in the prior art needs to determine the connection position between the dragging net and the dragging plate before the trawl net is put into the water body, which cannot be achieved during the fishing process. Realize the dynamic adjustment of the connection position between the drag net and the drag net pull plate, that is, it is impossible to dynamically adjust the attitude of the net plate during fishing to achieve the purpose of adjusting the depth of the trawl net water layer

Abstract

The invention relates to a euphausia superba trawl net plate variable water layer adjusting mechanism and method. The adjusting mechanism comprises a net plate, a lifting adjusting mechanism, a warp connecting block and a controller, wherein the lifting adjusting mechanism is installed on the inner side of the middle of the front end of the net plate along the height direction of the net plate, the warp connecting block is installed on the lifting adjusting mechanism and can be driven by the lifting adjusting mechanism to ascend and descend, the warp connecting block is connected with a warp,and the controller controls the driving of the lifting adjusting mechanism. A posture of the net plate can be dynamically adjusted in the fishing operation process, and the purpose of adjusting a depth of a trawl variable water layer is achieved.

Description

technical field [0001] The invention belongs to the technical field of trawl net panels, and in particular relates to an Antarctic krill trawl net panel variable water layer regulating mechanism and a method thereof. Background technique [0002] The existing net plate trawl net used for Antarctic krill fishing, its two sides are respectively connected with the fork plate of the net plate through connecting chains for dragging, and the drag plate of the net plate is provided with a drag plate, and the drag plate passes through the drag plate. The bridge is connected with the traction system of the fishing boat, and the fishing boat sails and pulls the net plate to achieve a balanced posture in the water body, unfolds the trawl net mouth and drags the trawl net for sea-sweeping fishing. [0003] As we all know, the purpose of adjusting the position of the trawl net in different water layers in the water body can be achieved by adjusting the inclination angle of the net plate ...
