The invention relates to the technical field of robots, in particular to a spiral propelling device of an underwater robot. The spiral propelling device comprises a housing, and a buoyancy cabin is welded to the top of the housing. A rubber air bag is arranged at the top of the buoyancy cabin; an electric valve is welded on one side of the buoyancy cabin; a steel cylinder is arranged on the outerwall of one side of the housing, a steel cylinder valve is arranged at one end of the steel cylinder, a connecting pipe is arranged at the end, away from the steel cylinder, of the steel cylinder valve, and the end, away from the steel cylinder valve, of the connecting pipe is connected with an electric valve; a motor is arranged in the housing, and a propeller is connected to one end of an outputshaft of the motor through a flat key. Through the arrangement of the rubber air bag, the steel cylinder and the electric valve, compressed carbon dioxide is contained in the steel cylinder; when theelectric valve is opened, the compressed carbon dioxide can enter the rubber air bag, the rubber air bag is made to expand, and the expanded rubber air bag has large buoyancy, so that the underwaterrobot can automatically float to the water surface when electric power is insufficient.
本发明涉及机器人技术领域,具体是一种水下机器人螺旋推进装置,包括壳体,壳体的顶部焊接有浮力舱,且浮力舱的顶部设置有橡胶气袋,浮力舱的一侧焊接有电动阀门,壳体的一侧外壁上设置有钢瓶,且钢瓶的一端设置有钢瓶阀门,钢瓶阀门远离钢瓶的一端设置有连接管,且连接管远离钢瓶阀门的一端与电动阀门连接,壳体的内部设置有电动机,且电动机的输出轴一端通过平键连接有螺旋桨。本发明通过设置的橡胶气袋、钢瓶和电动阀门,钢瓶内盛有压缩二氧化碳,在电动阀打开时,被压缩的二氧化碳则会进入橡胶气袋,使橡胶气袋膨胀,膨胀的橡胶气袋具有很大的浮力,会使得水下机器人在电力不足时自动上浮至水面。
