The invention discloses a centrifugal impeller type Bernoulli suction cup suitable for underwater operation. A waterproof direct current motor is coaxially installed on one end face of the suction cup shell, a Bernoulli base plate is coaxially arranged on the other end face of the suction cup shell, a hollow cavity is formed in the other end face of the suction cup shell, the centrifugal impeller is coaxially arranged in the hollow cavity, and a gap is reserved between the outer wall of an annular shell of the centrifugal impeller and the inner side wall of the suction cup shell. An output shaft in the center of the waterproof direct-current motor penetrates through the sucker shell and is connected with a rotating shaft in the center of the centrifugal impeller; the annular end face of the suction cup shell is fixed to one end face of an annular Bernoulli base plate, and an annular boss is arranged on the other end face of the Bernoulli base plate. A centrifugal impeller type suction cup is combined with the Bernoulli effect, larger adsorption force is achieved, water flowing out of an inner cavity of the suction cup at a high speed is reutilized, and the utilization efficiency of energy is improved. The centrifugal impeller type Bernoulli suction cup is simple in structure and convenient to control and mount, and large-scale manufacturing and engineering application can be achieved.
本发明公开了一种适用于水下作业的离心叶轮式伯努利吸盘。防水直流电机同轴安装在吸盘外壳的一端面上,吸盘外壳的另一端面同轴布置有伯努利底盘,吸盘外壳的另一端面开设有中空腔,离心叶轮同轴布置于中空腔内,离心叶轮的环形壳外壁与吸盘外壳内侧壁之间留有间隙,防水直流电机中心的输出轴穿过吸盘外壳与离心叶轮中心的旋转轴连接;吸盘外壳的环形端面固定在圆环形的伯努利底盘的一端面上,伯努利底盘的另一端面设有环形凸台。本发明将离心叶轮式吸盘与伯努利效应相结合,具有更大的吸附力,并且将吸盘内腔高速流出的水进行二次利用,提高了能源的利用效率。本发明结构简单,控制方便,安装便捷,可实现大规模制造和工程应用。
