Problems solved by technology

The Chinese patent application number 01138618.5 discloses a method for realizing a crawler-type multi-suction cup wall-climbing robot. The robot is large in size and complex in structure; CN97121896 discloses a "wall-climbing robot". Driven by the power, the fan generates a thrust pointing to the wall, so that the robot sticks to the wall; the efficiency of this wall climbing method is low, so the application is greatly limited
[0006] In short, the existing wall-climbing robots have high energy consumption, low wall-climbing efficiency, poor stability, and low usability

Embodiment 1

[0024] Embodiment 1, refer to Figure 1 to Figure 4 , the present invention comprises robot outer wall 1, gasket 2, driving device 3, centrifugal blower 4, and robot outer wall is provided with opening, makes robot outer wall and robot working plane form negative pressure chamber 5, and robot is provided with driving device, and on the driving device The pressure sensor 31 is installed, and the centrifugal blower is installed on the outer wall of the robot. By working through the centrifugal blower, the ratio of the gas extraction amount of the air outlet and the gas intake of the wall contact surface gap inlet is adjusted to reduce the internal pressure of the robot.

Embodiment 2

[0025] Embodiment 2, refer to Figure 1 to Figure 4 , the present invention can also include robot outer wall 1, sealing gasket 2, driving device 3, centrifugal blower 4, and robot outer wall is provided with opening, makes robot outer wall and robot working plane form negative pressure chamber 5, and robot is provided with air pressure automatic regulating valve 11. The air pressure automatic regulating valve is installed on the outer wall of the robot. When the internal pressure of the robot is too high, the air pressure regulating valve will open under the action of pressure, allowing the external airflow to slowly flow into the cavity, that is, increasing the gas intake volume of the cavity through the valve. The air pressure in the cavity is adjusted to adjust the atmospheric pressure received by the cavity. The rest are the same as any other embodiment of the present invention or the combination of more than two embodiments.

Embodiment 3

[0026] Embodiment 3, refer to Figure 1 to Figure 4 , the outer wall 1 of the robot of the present invention includes a side wall and a bottom wall, and a gasket is installed on the end face of the side wall of the robot to reduce the working contact plane gap of the robot and form a closed environment in the robot. The rest are the same as any other embodiment of the present invention or the combination of more than two embodiments.

Abstract

Disclosed is a negative-pressure self-adaptive adjusting device for a negative-pressure type wall-climbing robot. Through the negative-pressure self-adaptive adjusting device, the technical problems that an existing negative-pressure self-adaptive adjusting device is high in energy consumption, low in wall-climbing efficiency, poor in stability and low in usability are mainly solved. According to the main points of the technical scheme of the negative-pressure self-adaptive adjusting device, the negative-pressure self-adaptive adjusting device comprises a robot outer wall (1), a seal gasket (2), a driving device (3) and a centrifugal fan (4); the robot outer wall is provided with an opening, and thus the robot outer wall and a robot working plane form a negative-pressure cavity; and the robot is provided with a pressure controlling device. The negative-pressure self-adaptive adjusting device is mainly applied to the fields of robot technology and automatic control.

Description

technical field [0001] The invention belongs to the field of robot technology and automatic control, in particular to a device capable of self-adaptive adsorption force used on a wall-climbing robot. Background technique [0002] With the development of modern science and technology, robots capable of climbing walls are required in various fields, such as anti-terrorist investigation, high-rise building inspection, and wall cleaning. This kind of robot can freely travel on walls at various angles, and at the same time carry a variety of sensors to complete tasks. [0003] At present, it has been found out from the existing negative pressure wall-climbing robot, published materials and related patent materials that the negative pressure wall-climbing robot simply works at a constant speed through a centrifugal air pump during the movement of the robot; When the sealing effect of the negative pressure chamber of the wall-climbing robot is constant, a constant adsorption force...
