The invention discloses a seabed shrimp and crab catching device capable of replacing a catching area through air injection displacement. The device comprises a storage box, the storage box is fixedlyconnected with a floating air bag, the floating air bag is used for providing buoyancy for floating, the storage box is fixedly connected with a motor box, and the motor box is internally fixedly connected with a power motor; and the power motor is in power connection with two power shafts in a bilateral symmetry manner, the power shaft at the right side is fixedly connected with a pressing cam,and the inner wall of the right side of the storage box is rotationally connected with a rotating connecting piece. According to the seabed shrimp and crab catching device capable of replacing the catching area through air injection displacement, an air injection pushing device is arranged, air is collected in the catching cage recycling process and then released, and then the device moves by a certain distance on the sea surface, so that the purpose of changing the catching area is achieved; and the automatic cage catching fishing work is continued, so that the catching efficiency is kept.

    本发明公开了一种喷气位移更换捕捞区域的海底虾蟹捕捞装置,包括存储箱,所述存储箱固定连接有漂浮气囊,所述漂浮气囊用于提供浮力漂浮,所述存储箱固定连接有电机箱,所述电机箱内固定连接有动力电机,所述动力电机左右对称动力连接有两个动力轴,右侧的所述动力轴固定连接有下压凸轮,所述存储箱右侧内壁转动连接有转动连接件;本发明的一种喷气位移更换捕捞区域的海底虾蟹捕捞装置,本设备设有喷气推动装置,通过在对捕捞笼回收过程中进行集气,随后进行释放,进而使得本设备在海面进行一段距离的位移,从而实现改变捕捞区域的目的,继续进行自动投笼捕捞工作,进而保持捕捞效率。
