The invention relates to the technical field of propelling devices, and discloses a propeller device capable of reducing organism following and preventing entrainment. The propeller device comprises a mounting rack, a surrounding cylinder is fixedly mounted on the lower end surface of the mounting rack, rotating motors are fixedly mounted on the inner wall of the surrounding cylinder in a bilateral symmetry manner, a power shaft is mounted on each rotating motor in a power manner, a rotary mounting plate is fixedly mounted on the outer side end face of the power shaft, a tightening cylinder is fixedly mounted on the lower side of the rotary mounting plate, and a shifting mounting block is mounted on the tightening cylinder in a liftable manner. According to the propeller device capable of reducing organism following and preventing entrainment, through arrangement of a deformation protection system, in the propelling and moving process, a driving closing device provided with a double-layer protection arc cover can conduct combination and closing on the propeller surrounding cylinder, so that entrainment of small fishes is greatly reduced, and accidents caused by following and foraging of other fishes around a vessel are reduced.
本发明涉及推进装置技术领域,公开了一种可减少生物跟随并防止卷入的螺旋桨装置,包括安装架,所述安装架下端面固定安装有包围筒,所述包围筒内壁左右对称固定安装有旋转电机,所述旋转电机动力安装有动力轴,所述动力轴外侧端面固定安装有旋转安装板,所述旋转安装板下侧固定安装有收紧筒,所述收紧筒可升降的安装有拨动安装块;本发明的一种可减少生物跟随并防止卷入的螺旋桨装置通过变形防护系统的设置,可以当在推进移动过程中,使得安装有双层防护弧罩的驱动闭合装置对螺旋桨包围筒进行合体闭合,从而大大减少小型鱼类的卷入,进而减少了船舰周围其他鱼类追随觅食造成事故。
