The invention discloses an anti-wear method for trawling fishing of a fishing boat, and belongs to the technical field of marine fishing methods. The method comprises the steps of S1 to S5, a fishing structure is connected to a ship body structure through a traction rope, so that the fishing structure can synchronously advance along with the ship body structure; meanwhile, the inlet end of the fishing structure sinks in a seabed water area through a balance weight beam structure so as to catch shrimps, crabs and fishes in the seabed water area, the balance weight beam structure can climb over and break away when touching a special seabed landform in the advancing process, and the tail end of the fishing structure can float up to the water area above the seabed through a tail floating structure, so that the wear probability of the middle tail end of the fishing structure under the special landform is reduced; and in addition, a telescopic bottom supporting structure arranged between the balance weight truss structure and the tail floating structure can play a role in supporting and protecting the fishing structure in a full-extending path, and the situation that the fishing structure locally sinks to make contact with a special landform area and consequently wear is caused is prevented.
本发明公开了一种用于渔船拖网捕捞的防磨损方法,属于船用捕捞方法技术领域。包括步骤S1‑S5中通过牵引绳索将捕捞结构与船体结构相连,使捕捞结构能跟随船体结构同步前进;同时通过配重桁杆结构使捕捞结构的入口端下沉于海底水域,以捕捞位于海底水域的虾蟹鱼类,配重桁杆结构在前进过程触及到特殊海底地貌时能够翻越脱离,并通过尾浮结构使捕捞结构的尾端能够上浮于海底上方水域,以减少捕捞结构的中尾端在特殊地貌下的磨损概率;此外通过设于配重桁杆结构与尾浮结构之间的伸缩托底结构能够对捕捞结构起到全延伸路径的承托防护作用,防止捕捞结构局部下沉触及到特殊地貌区域而导致磨损。
