The invention discloses an underwater thruster. The underwater thruster comprises a central shell, a propeller and a thrusting motor, a guide shaft and two guide plates are arranged at the front part of the central shell; an adjusting gear is rotationally connected into the central shell; a counter weight part is arranged at the non-central position of the adjusting gear; a control part is arranged on the outer wall of the central shell; when the advancing direction of the central shell faces the right upper portion, the propellers rotate to drive the central shell to move upwards. When the advancing direction of the central shell does not face the right upper portion, the central shell moves to enable the guide plates to move upwards under driving of water resistance, and then the movement direction of the central shell deflects upwards. The underwater propeller can be used as an underwater propeller, so that the pleasure of playing water is increased; an automatic lifesaving function is achieved, the central shell moves towards the position above the water surface, and the life of a user is saved; the operation is simple and convenient, and a user does not need to carry out other lifesaving operations.
本发明公开了一种水下推进器,包括有中央壳体、螺旋桨以及推进电机;中央壳体前部设置有导向轴以及两个导向板;中央壳体内转动连接有调节齿轮;调节齿轮的非中央位置设置有配重部;中央壳体外壁设置有操纵部;当中央壳体的前进方向朝向正上方时,螺旋桨转动带动中央壳体向上方运动;当中央壳体的前进方向没有朝向正上方时,中央壳体运动使得导向板在水阻力的驱动下向上运动,进而使得中央壳体的运动方向向上方偏转。本发明能够作为水中推进器使用,增加了玩水的乐趣;具有自动救生功能,中央壳体向水面上方运动,挽救使用者生命;操作简单方便,无需使用者在进行其他救生操作。
