The invention belongs to the technical field of underwater operation, and particularly relates to an adsorption device for ROV underwater operation, the adsorption device comprises a frame body, a negative pressure generation mechanism and an adsorption mechanism, the frame body is used for bearing underwater operation equipment; the negative pressure generating mechanism comprises a water pump, a jet device connected with the water pump and a plurality of connecting pipes, an outlet of the water pump is connected with an inlet of the jet device, the connecting pipes are connected with a suction inlet of the jet device, and the suction inlet of the jet device can form negative pressure; the adsorption mechanism comprises a plurality of suckers; the connecting pipe is connected with the suction cup, the negative pressure generating mechanism operates to form negative pressure between the suction cup and a working face, the water pump is started, water flow is sprayed out of an outlet of the jet device to form negative pressure, water in the suction cup is sucked away under the action of the negative pressure, and the suction cup is stably sucked to a dam body. Therefore, counter-acting force generated in the operation process on a slope face, a horizontal face and a vertical face is overcome, the underwater robot is prevented from generating large floating or overturning, and stable operation of the underwater robot is guaranteed.
本发明属于水下作业技术领域,具体是涉及到一种用于ROV水下作业的吸附装置,包括架体、负压产生机构和吸附机构,架体用于承载水下作业设备;负压产生机构包括水泵、与水泵连接的射流器以及若干连接管,水泵的出口与射流器的进口连接,若干连接管与射流器的吸入口连接,射流器的吸入口能形成负压;吸附机构包括若干吸盘;连接管与吸盘连接,负压产生机构运行能在吸盘与作业面间能形成负压,水泵开启水流从射流器的出口喷出形成负压,在负压的作用将吸盘的水吸走,使吸盘稳定吸附在坝体上,从而克服在斜坡面、水平面和直立面作业过程中产生的反作用力,避免造成水下机器人产生较大浮动或倾覆,保证下水机器人稳固作业。
