A ducted supercharged outboard motor propeller protection cover comprises a front end framework, a tail end framework and protection wing plates. The tail end framework and the front end framework are arranged at intervals; the protective wing plates are of sheet structures and are horizontally arranged, one ends of the protective wing plates are fixedly connected with the front-end framework, the other ends of the protective wing plates are fixedly connected with the tail-end framework, every two protective wing plates form a group, and the two protective wing plates in the same group are located in the same horizontal plane. The protective wing plates are arranged in the height direction, a circulation gap for water flow to pass through is formed between every two adjacent protective wing plates, the protective wing plates, the front-end framework and the tail-end framework form a containing space for surrounding and containing the outboard engine blades, and the protective wing plates are made of metal. The outboard motor paddle protection device is a protection cover which is novel in structure, does not increase advancing resistance in the using process and can provide reliable protection for the outboard motor paddle.

    一种涵道式增压型船外机螺旋桨保护罩,包括前端骨架、尾端骨架以及防护翼板;尾端骨架与前端骨架间隔设置;防护翼板为片状结构,防护翼板水平设置,防护翼板的一端与前端骨架固定连接,防护翼板的另一端与尾端骨架固定连接,防护翼板以两个为一组,同一组中的两个防护翼板位于同一个水平面内,防护翼板设置有多组、并在高度方向上罗列设置,相邻的两个防护翼板之间具有用于水流通过的流通间隙,防护翼板、前端骨架以及尾端骨架形成有用于包围容纳船外机桨叶的容纳空间,防护翼板的制造材料为金属。本发明所提供的船外机桨叶保护装置是一种结构新颖,且使用过程中不会增加行进阻力,同时还能够对船外机桨叶提供可靠的防护的保护罩。
