[0064] Step 1: Extend the hydraulic mechanical arm on the cleaning vehicle to move the cleaning tool holder above the photothermal mirror;

[0065] Step 2: Use the distance sensor to measure the distance between the cleaning tool holder and the mirror surface, and then adjust the telescopic part of the tool holder to make the brush cleaning part fit well with the mirror surface;

[0068] Mode 2: Low temperature working mode (ambient temperature below zero degrees)

[0069] Since the ambient temperature is below zero, high-pressure water cleaning cannot be used. Therefore, high-temperature steam is used to clean the collector tubes of the solar thermal power station.

[0070] Step 1: Extend the hydraulic mechanical arm on the cleaning vehicle to move the cleaning tool holder above the photothermal mirror;

[0071] Step 2: Use the distance sensor to measure the distance between the cleaning tool holder and the mirror surface, and then adjust the telescopic part of the tool holder to make the brush cleaning part fit well with the mirror surface;

[0072] Step 3: The high-temperature steam pipeline flushes the collector tube with high-temperature steam. The first pipeline rotates the hydraulic motor, which drives the brush plate to rotate and dry-brush the solar thermal mirror surface;

[0073] Step 4: During the cleaning process, the distance between the cleaning tool holder and the mirror is measured in real time through the distance measuring sensor system, and the telescopic part is adjusted to maintain a relatively stable fit between the brush plate and the mirror, ensuring the safety of the cleaning process, avoiding the collision of the cleaning tool holder with the mirror, and ensuring the cleaning effect.
