The working process and the principle of the tower-type photothermal power generation reflector mirror surface cleaning device are as follows:
the tower type photo-thermal power generation reflector mirror surface cleaning device is fixed on a forklift moving cantilever 24, and when the reflector mirror surface 25 needs to be cleaned, a driver operates the tower type photo-thermal power generation reflector mirror surface cleaning device to drive a cleaning forklift to clean the reflectors one by one; before the mirror surface 25 of the reflector is cleaned, the first cylinder 17 and the second cylinder 23 are both in a contraction state, at the moment, the first rotating frame 22 and the second rotating frame 21 are driven to rotate to the outermost side, and the distance between the support plate 1 and the connecting plate 18 is the minimum at the moment; when the vehicle runs to the position near the reflector, the position of the forklift needs to be adjusted to enable the support plate 1 to be approximately parallel to the reflector surface 25, the vehicle stops when the rolling brush 4 and the roller 9 are about to contact the reflector surface 25, the first air cylinder 17 and the second air cylinder 23 are controlled to extend, the first rotating frame 22 and the second rotating frame 21 rotate inwards, the distance between the support plate 1 and the connecting plate 18 is gradually increased until the rolling brush 4 and the roller 9 contact the reflector surface 25; even if the mirror surface 25 is not in contact with and not parallel to the support plate 1 at first, under the pushing of the first cylinder 17 and the second cylinder 23, the support plate 1 will rotate to be attached to the mirror surface 25 after contacting the mirror surface 25, and under the pushing of the first cylinder 17 and the second cylinder 23, a certain pressure exists between the rolling brush 4 and the mirror surface 25, which is beneficial to the cleaning work of the rolling brush 4.
Under the drive of the forklift moving cantilever 24, the cleaning device starts to move on the reflecting mirror surface 25, at the moment, only the rolling brush 4 and the roller 9 are in contact with the reflecting mirror surface 25, so that the fact that the water cleaning device and the air cleaning device are not in direct contact with the reflecting mirror surface 25 is guaranteed, the reflecting mirror surface 25 is protected, and under the guiding effect of the roller 9, the cleaning device is more stable to move.
In the process of cleaning the mirror surface 25 of the reflector, the air knife 14 obtains air, the square tube 5 obtains water, and the motor 11 works, at the moment, the air knife 14 forms an air curtain, the nozzle 6 arranged on the square tube 5 sprays water, and the rolling brush 4 starts to rotate; assuming that the cleaning operation is from top to bottom, the air cleaning device is located at the lowest end, then the water cleaning device is located, the brushing device is located at the top end, when the cleaning device is from top to bottom, the air cleaning device is firstly used for cleaning the reflector mirror surface 25, an air curtain blown out by the air knife 14 is blown to the reflector mirror surface 25 at a certain angle to remove particles with larger particle size and most of dust, then water in the square pipe 5 is sprayed out in a fan shape through the nozzle 6 to wash away residual dust, and finally residual water and dust on the reflector mirror surface 25 are taken away under the brushing cleaning of the rolling brush 4.
After the mirror surface 25 of the reflector is cleaned, the air knife 14 stops supplying air, the square pipe 5 stops supplying water, the motor 11 stops working, the first air cylinder 17 and the second air cylinder 23 are controlled to be in a contraction state, the distance between the support plate 1 and the connecting plate 18 is reduced, the cleaning device leaves the mirror surface 25 of the reflector, the cleaning of the mirror surface 25 of the reflector is completed, and the reflector moves away from a cleaning forklift to go to the next cleaning position.
