The invention discloses a novel marine propeller protective cover. The protective cover comprises a front protective ring and a rear protective ring, wherein a plurality of fixing rods are arranged between the front protective ring and the rear protective ring, openings are formed in the top of the front protective ring and the top of the rear protective ring, U-shaped fixing parts are arranged in the openings, and a bottom fixing assembly is arranged on a lower portion of the rear protective ring. Grids, arranged in front of a propeller, of the protective cover are omitted, and stability and strength of the protective cover are maintained through the front protective ring and the rear protective ring. The reduction effect of the protective cover on the water absorption force of the propeller can be reduced, the power of the propeller is improved, and the good protection effect on the propeller is achieved. The protection cover is fixed from the upper portion and the lower portion at the same time through the U-shaped fixing part and the bottom fixing assembly, the fixing effect is good, and the protection effect on the propeller is good.

    本发明公开了一种新型船用螺旋桨防护罩,包括前防护圈和后防护圈,前防护圈与后防护圈之间设有若干固定杆,前防护圈、后防护圈在顶部均设有开口,开口内设有U型固定部,后防护圈在下部位置设有底部固定组件。本发明取消防护罩设于螺旋桨前方的栅格,并通过前、后防护圈维持防护罩的稳定性和强度。本发明可以减少防护罩对于螺旋桨吸水力的减小效应,提高螺旋桨动力,并对螺旋桨起到良好的保护效果。本发明通过U型固定部和底部固定组件对防护罩从上方和下方进行同时固定,固定效果好,对螺旋桨的保护效果好。
