The reciprocating direct pushing type underwater propeller comprises water pushing pieces which are arranged in the same row at equal intervals, and baffles surrounding the water pushing pieces are arranged outside the water pushing pieces; a limiting shaft located on the lower side of the rotating shaft is fixedly arranged in the baffle, the distance between the limiting shaft and the rotating shaft is smaller than the length of the water pushing piece, a bottom plate is arranged on the upper side of the baffle, a vertical push rod is arranged on the bottom plate in a penetrating mode, and a supporting piece is fixedly connected between the push rod and the top end of the baffle. A sealed shell wrapping the bottom plate and the top plate is arranged on the edge of the bottom plate, a supporting column matched with the push rod and a rotating wheel set are fixedly arranged between the bottom plate and the top plate, and a winding wheel matched with the rotating wheel set is further arranged on the bottom plate; a sliding assembly capable of enabling the push rod to vertically slide is arranged on the supporting column; and motors for controlling rotation are arranged on the winding wheels. The invention aims at providing the underwater propeller which can solve the problem that a traditional underwater propeller is low in propelling efficiency and is suitable for miniaturization.
本发明公开了一种往复直推式的水下推进器,包括同排并等间距设置的推水片,所述推水片外部设置有围住推水片的挡板;所述挡板内固定设置有位于转动轴下侧的限位轴,限位轴与转动轴之间的间距小于推水片的长度,挡板的上侧设置有底板,底板上穿设有竖直的推杆,推杆与挡板顶端之间固定连接有支撑件;所述底板边缘设置有包在底板和顶板外部密封的外壳,底板与顶板之间固定设置有与推杆配套的支撑柱、转动轮组,底板上还设置有与转动轮组配套的绕线轮;所述支撑柱上设置有能够让推杆竖向滑动的滑动组件;所述绕线轮上均设置有控制旋转的电机。本发明旨在提供一种能够解决传统水下螺旋桨推进器推进效率低,适合小型化的水下推进器。
