The invention relates to a novel marine propeller device which comprises a spiral plate and a center shaft, the spiral plate is arranged on the center shaft in a surrounding mode, the front end of thespiral plate is small and the rear end of the spiral plate is large, and therefore it is guaranteed that a propeller can smoothly rotate after receiving power of a transmission shaft and generates sufficient reaction thrust with water to push a ship to move forwards; and the appearance is in circular arc transition, so that uniform front and back power output is guaranteed, mutual interference isavoided, cavitation bubbles are reduced to the maximum extent, the resistance is reduced, and the propeller is well protected. The power loss and damage to the propeller caused by cavitation are reduced, the power output efficiency is improved, and the spiral plate can be increased at will, so that the contact surface of the spiral plate and water can be larger, the reaction force of the water isgreatly enhanced, the slip ratio is greatly reduced, the stability and efficiency of power transmission are improved; the spiral plates can be in one group or multiple groups; the device has the advantages that the integral structure is simple, and the power output efficiency is higher.
本发明涉及一种新式船用螺旋桨装置,包括螺旋板和中心轴,螺旋板围绕布置在中心轴上,螺旋板前端小,后端大,以保证螺旋桨在收到传动轴的动力后可以顺畅旋转,从而和水产生充分反作用推力,推动船只前行。并且外形为圆弧状过渡,从而保证了前后的动力输出均匀而不会产生相互干扰,最大化的减少了空泡,减少了阻力,对螺旋桨起到了很好的保护。减小了空泡带来的动力流失及对螺旋桨的破坏作用,使得输出动力的效率得以提高,螺旋板可以随意增长,因此,螺旋板和水的接触面可以变得更大,使得水的反作用力大为加强,大幅减少滑脱比,从而增加动力传输的稳定性和效率,螺旋板可以是一组或多组,本装置整体结构简单,输出动力的效率较高。
