The invention discloses a thruster protection device and a propeller thruster. The thruster protection device comprises a mounting frame, a connecting propeller and a ship body; the protection structure surrounds the propeller, the upper portion of the installation frame penetrates out of the protection structure, the protection structure comprises a front protection cover and a rear protection cover, a water inlet grating is arranged on the front portion of the front protection cover, a clamping portion is arranged on the rear portion of the front protection cover, and a buckling portion used for being clamped with the clamping portion is arranged on the front portion of the rear protection cover. The front protective cover and the rear protective cover are connected with each other through the buckling part and the clamping part, so that disassembly, cleaning and installation are more convenient; the water inlet grating can prevent fishes or entanglements from easily entering the vicinity of the propeller, so that the propeller is protected, and meanwhile, the biological hazard and the damage of the propeller are reduced; the front protective cover and the rear protective cover jointly form a propeller duct to limit the movement direction of fluid and reduce the power delay of the propeller.

    本发明公开了一种推进器保护装置及螺旋桨推进器,包括安装架,连接螺旋桨和船体;保护结构,包围住螺旋桨,安装架的上部从保护结构中穿出,所述保护结构包括前保护罩和后保护罩,所述前保护罩的前部设置有进水口格栅且后部设置有卡接部,所述后保护罩的前部设置有用于与所述卡接部相卡合的卡扣部。前保护罩和后保护罩通过卡扣部和卡接部相互连接,拆卸清理和安装更加方便;进水口格栅可使得鱼类或者缠绕物不容易进入螺旋桨附近,在保护螺旋桨的同时减少生物危害和螺旋桨自身的损坏;前保护罩和后保护罩共同组成螺旋桨涵道,限制流体的运动方向,减少螺旋桨的动力迟滞。
