本发明属于桨内冷却空泡抑制技术领域,具体涉及一种带有桨内冷却空泡抑制装置的螺旋桨。本发明是对传统螺旋桨的一种改进,在螺旋桨桨轴内设置水导管,在水导管外部设置冷却液导管以及冷却循环装置,通过冷却液管‑散热板‑冷却液储存箱‑冷却液管进行冷却循环。水导管在桨毂内部将冷却后的水送入每个螺旋桨叶片内部,通过螺旋桨桨叶叶背处设置的喷水口,将冷却之后的水通过喷水口喷出,使螺旋桨桨叶叶背处的水温下降,减少了空泡的产生。本发明具有结构简单,能较好的减少螺旋桨空泡的产生等特点,在船舶推进上具有良好的实用性。

    The invention belongs to the technical field of in-propeller cooling cavitation inhibition, and particularly relates to a propeller with an in-propeller cooling cavitation inhibition device. A traditional propeller is improved, a water guide pipe is arranged in a propeller shaft of the propeller, a cooling liquid guide pipe and a cooling circulation device are arranged outside the water guide pipe, and cooling circulation is conducted through a cooling liquid pipe, a heat dissipation plate, a cooling liquid storage box and a cooling liquid pipe. The water guide pipe feeds cooled water into each propeller blade in a propeller hub, and cooled water is sprayed out through a water spraying openings formed in blade backs of propeller blades, so that the water temperature of the blade backs of the propeller blades is reduced, and cavitation bubbles are reduced. The propeller has the advantages of being simple in structure, capable of well reducing generation of cavitation bubbles of the propeller and the like, and has good practicability in ship propulsion.
