Abstract

The invention relates to a high-aspect-ratio double-arc surface-middle layer trawl board which comprises a main panel, wherein the main panel is in a vertical double-arc structure; a cross section is double-arc internal hollow; an upper top board is mounted at the top of the main panel; a lower top board is mounted at the bottom of the main panel; a middle reinforcing board is mounted in the middle of the main panel; reinforcing rib boards are mounted between the upper top board and the middle reinforcing board, and between the middle reinforcing board and the lower top board respectively; the upper top board, the middle reinforcing board, the lower top board and the reinforcing rib boards divide an inner space of the main panel into four watertight spaces; a guide board is mounted on the front side of the main panel; a tow rope connecting frame is mounted at one end, close to the front side, of the middle reinforcing board; a cross rope connecting frame is mounted on the main panel close to the top of the rear side of the upper top board at the top, and close to the top of the main panel; and cross rope connecting frames are mounted at the rear end, close to the upper top board and the lower top board, of the main panel. The high-aspect-ratio double-arc surface-middle layer trawl board is located on a target water layer, has a greater expansionary force and smaller water resistance, and is applicable to surface-middle layer trawling.

Description

technical field [0001] The invention belongs to the technical field of marine fishery fishing tools, and in particular relates to a large-aspect-ratio double-arc surface-middle layer trawl net plate. Background technique [0002] The trawl net plate is the main attachment to realize the expansion of the net gear in the trawling operation of the fishing boat. During production, the appropriate mesh type should be selected according to the characteristics of the sea area, the power of the fishing boat, the fishing target, the operating fishery, the fishing water layer, and the conditions of the facilities. At present, the types of mesh panels commonly used in trawl fishery include oval, rectangular, "V"-shaped, vertical curved surface, slotted, and compound wing mesh panels. Among them, the advantages of large aspect ratio vertical curved mesh panels are large lift coefficient, small drag coefficient, and high efficiency of mesh panels, which are mainly used for middle-level ...
