The invention discloses a fishing boat front extension type trawl device based on water surface fishing, and belongs to the technical field of marine equipment. The trawl device comprises a telescopic positioning structure, a net opening supporting structure, a fishing net body, a fishing lifting structure, a lifting segmentation structure and a lifting sealing structure. According to the device, the telescopic driving structure can drive the telescopic positioning structure to build the fishing net body in front of the ship body structure, and the inlet end of the fishing net body is maintained at a preset distance in front of the ship body structure by means of the net opening supporting structure, so that fish schools located in a top-layer water area are fished to enter the fishing net body from the inlet end; the lifting segmentation structure and the lifting sealing structure can be synchronously driven through the lifting motion of the fishing lifting structure, fishes gathered at the tail end of the fishing net body can be independently erected and lifted through the lifting segmentation structure, and an outlet channel can be formed at the tail end of the fishing net body through the lifting sealing structure and further driven to ascend; and the fish can fall into a specific container of the ship body structure by virtue of self gravity.
本发明公开了一种基于水面捕捞的渔船前置延展式拖网装置,属于船用设备技术领域。包括伸缩定位结构、网口支承结构、捕捞网体、捕捞起落结构、起升分段结构和升降封口结构;该装置能够通过伸缩驱动结构带动伸缩定位结构在船体结构的前方建立捕捞网体,并借助网口支承结构将捕捞网体的入口端维持在船体结构前方的预定距离处,以捕捞位于顶层水域的鱼群从入口端进入捕捞网体;通过捕捞起落结构的起落运动能够同步带动起升分段结构和升降封口结构,通过起升分段结构能够将聚集在捕捞网体尾端的鱼类被单独架起上升,通过升降封口结构可在捕捞网体的尾端形成出口通道并进一步带动出口通道上升,使得鱼类能够借助自身重力落入船体结构的特定容器内。
