AI Technical Summary
The negative pressure adsorption device of the existing wind turbine blade inspection robot cannot adjust the adsorption force in real time according to the geometric changes of the blade surface, resulting in local sealing failure and affecting the stability and energy consumption of the robot.
The power system device with dynamic negative pressure adsorption force adjustment function achieves a strong coupling response between negative pressure supply and dynamic force state of the machine body by combining the load current of the track drive motor and the real-time tilt angle and motion state of the machine body obtained by the inertial measurement unit with multi-zone independent pressure sensing and negative feedback adjustment mechanism, and flexibly adjusts the actual negative pressure of each independent negative pressure zone.
It improves the stability of the machine body, avoids energy waste caused by global constant high negative pressure, reduces the risk of local seal failure, enhances track friction and adsorption, and improves the detection efficiency and safety of the wind turbine blade inspection robot.
