Description

technical field [0001] The invention relates to an automatic mechanical part, in particular to an underwater vibration adsorption device. Background technique [0002] Vibration adsorption devices are widely used in fields such as wall-climbing robots and heavy object grasping, which use vibration adsorption to achieve attachment. Assuming that the pressure inside the sucker cavity is equal to the external pressure, the state is the equilibrium state. When the skirt of the sucker is in good contact with the wall in the natural state, its height is the equilibrium height, and the height of the sucker is the equilibrium height under the action of external force. The phenomenon that the wall is adsorbed by vibrating with a certain amplitude as the center is called vibration adsorption. In the prior art, the adsorption device is mostly realized by negative pressure suction cup. In order to achieve the adsorption effect, it is usually necessary to connect an external power sourc...

AI Technical Summary

Problems solved by technology

In the prior art, the adsorption device is mostly realized by negative pressure suction cup. In order to achieve the adsorption effect, it is usually necessary to connect an external power source such as an air pump to generate negative pressure inside the suction cup, which makes the driving mechanism complex and consumes high power. In addition, the overall structure takes up The space is large, the work limitations are large, and the coordination between the suction cups is not high, the safety of the robot is reduced, and the robot cannot be continuously adsorbed on the wall

[0003] Moreover, although the existing vibration adsorption module in the air can realize the stable adsorption of the suction cup, it cannot be used in liquid environments such as underwater
