The invention belongs to the technical field of wall-climbing robots. The negative-pressure adsorption wall-climbing robot comprises a chassis, a suction unit, a suction unit and a suction unit, the first adsorption unit is connected to one end face of the base plate, and the air outlet end of the first adsorption unit communicates with the suction unit; the second adsorption unit is arranged in the first adsorption unit and fixed to the suction unit, an opening and closing piece is arranged on the second adsorption unit, and the second adsorption unit is switched between an opening and closing state and a closed state through the opening and closing piece; and in the opening and closing state, the air outlet end of the second adsorption unit is communicated with the suction unit. The first adsorption unit and the second adsorption unit can be arranged on the chassis, and when a gap is generated between the adsorption end of the first adsorption unit and the surface of a structural body in the advancing process of the chassis, and the adsorption effect is reduced, communication between the second adsorption unit and the suction unit is achieved through the opening and closing piece; and the second adsorption unit is adsorbed on the surface of the structural body, so that the robot is prevented from being desorbed from the structural body.

    本发明属于爬壁机器人技术领域。公开一种负压吸附的爬壁机器人,包括:底盘,内部设置有抽吸单元;第一吸附单元,连接在底盘的一端面上,且第一吸附单元出气端与抽吸单元连通;第二吸附单元,设置在第一吸附单元内且固定在抽吸单元上,第二吸附单元上设置有开合件,第二吸附单元通过开合件在开合状态与封闭状态切换;其中,在开合状态,第二吸附单元出气端与抽吸单元连通。本发明能够实现在底盘上设置第一吸附单元和第二吸附单元,当底盘在行进过程中,第一吸附单元吸附端与结构体表面产生间隙,导致吸附效果降低时,通过开合件实现第二吸附单元与抽吸单元的连通,以使得第二吸附单元吸附在结构体表面,从而避免机器人与结构体脱附。
