The invention discloses a ship propelling device capable of protecting an impeller. The device comprises a box body. A storage groove with a downward opening is formed in the bottom wall of the box body; a telescopic mechanism is arranged in the storage groove; a winder groove with a downward opening is formed in the top wall of the storage groove; an upper gear is arranged in the winder groove; awinder is fixedly arranged on the front end wall of the upper gear; the rear end of the upper gear is fixedly connected with a motor shaft; the rear end of the motor shaft is in power connection withthe motor; and the motor shaft is rotationally connected with the box body. Dumping mechanisms which are symmetrically arranged on the two sides of the storage groove left and right are arranged in the box body; a storage box is fixedly arranged on the bottom wall of the box body; a contracted baffle plate can be stored in the storage box; floating object collecting mechanisms that are arranged on the two sides of the lower reel cavity and the baffle plate are arranged on the bottom wall of the box body in a bilateral symmetry mode. The impeller can be protected, the service life of the impeller is prolonged; the impeller can be stored when not used; and floating objects in the advancing direction of the impeller can be collected when the impeller works to prevent the impeller from beingdamaged by the floating objects.

    本发明公开了一种保护叶轮的船舶推进装置,包括箱体,箱体底壁设置有开口向下的收纳槽,收纳槽内设置有伸缩机构,收纳槽顶壁设置有开口向下的绕线器槽,绕线器槽内设置有上齿轮,上齿轮前端壁固定设置有绕线器,上齿轮后端与电机轴固定连接,电机轴后端与电机动力连接,电机轴与箱体转动连接,箱体内设置有左右对称设置于收纳槽两侧的倾倒机构,箱体底壁上固定设置有收纳盒,收纳盒内可储存收缩后的挡板,箱体底壁左右对称设置有位于下绕线轮腔与挡板两侧的漂浮物收集机构,可以保护叶轮,增长其使用寿命,在叶轮不使用时可以收纳起来,在叶轮工作时可以收集齐其前进方向上的漂浮物避免漂浮物损伤叶轮。
