[0045] like Figure 2 , Figure 3 , Figure 4 , Figure 6As shown, the water washing mechanism 1 comprises an enclosure 10, a storage room 11 and a water storage room 12 which are arranged in sequence from bottom to top. The enclosure 10 is only open at the bottom and has a hollow cavity. A rotating brush 13 is arranged on the top inner wall of the enclosure. Water inlets 14 are arranged at both ends of the side walls of the enclosure 10. A water pump 15 is arranged at one end of the water storage room 12. The water pump 15 and the water inlet 14 are connected by a hose. A plurality of nozzles connected by water pipes are arranged on the inner wall of the enclosure 10. The water washing motor is arranged in the storage room 11 and drives the rotating brush 13 to rotate through a rotating rod. The water storage room 13 is used to provide a water source for the water washing mechanism. The water pump 15 is used to provide the water in the water storage room 12 to the rotating brush 13 and provide sufficient water pressure. A plurality of rotating brushes 13 can be arranged. The rotating brush 13 has biological hair as a brushing tool to contact the mirror surface. The enclosure 10 surrounds the rotating brush 13 to prevent dust and water stains generated during the water washing process from contaminating the cleaned mirror surface. The water storage room 12 is used to store external water and supply the rotating brush 13. When in use, the water in the water tank 12 is pumped out through the water pump 15, and flushed into the space enclosed by the enclosure 10 through the water outlet 14. A number of nozzles connected by water pipes are arranged on the inner wall of the enclosure 10, so that the water flow is more dispersed and the cleaning is cleaner during water washing. Considering the weight problem, a small water storage room 12 can be set up, and water is pumped from under the mirror into the water tank, and then transported into the water washing mechanism. When work is needed, after power is turned on, the water washing button and the scroll button are controlled, the rotating brush rotates, the body is driven, and the water pump starts to pump water after a certain delay.

[0046] like Figure 2 , Fig. 9 As shown, the wiping mechanism 2 includes two motor housings 20 and two racks 21, the two motor housings 20 are respectively located at the two ends behind the washing mechanism 1, the two racks 21 are arranged between the two motor housings 20, a bottom plate 22 is fixedly connected between the bottoms of the two racks 21, a sponge block is bonded to the bottom of the bottom plate, the wiping motor is arranged in the motor housing 20, and the rack 21 is driven by the wiping motor to move up and down by meshing with the gear 23 driven by the wiping motor. The wiping motor is started to rotate forward and reverse by the wiping button, driving the transmission shaft on the wiping motor to rotate, and the transmission shaft drives the connected gear 23 to move, thereby driving the rack 21 to move up and down, so that the distance between the bottom plate 22 and the mirror surface can be adjusted. When the height of the mirror surface reaches the optimal contact position between the bottom plate 22 and the mirror surface, the mirror surface washed by water can be wiped better. The bottom plate and the sponge block are connected by adopting a physical hook and loop method, and it is also convenient to replace when the sponge block is contaminated.

[0047] like Figure 2 , Figure 5As shown, the dust collection mechanism 3 includes a dust collection box 30 and a suction pipe 31 arranged at the front end of the dust collection box 30 and interpenetrating with the dust collection box 30. The dust collection box 30 and the suction pipe 31 are welded. A fan 32 and a detachable suction box 33 are arranged in the dust collection box 30. An opening for pulling the suction box 33 is arranged on one side of the dust collection box 30. An air cushion 34 is arranged at the pipe mouth of the suction pipe 31. When the fan 32 is started by the wind blowing button, the dust particles on the heliostat are sucked into the dust collection box 30 through the suction pipe 31. After dust collection, the suction box 33 can be taken out to dump the garbage. The large space of the suction box 33 can reduce the frequency of taking out. Multiple fans 32 and suction pipes 31 can be arranged horizontally to increase the dust collection range and effect. The pipe mouth of the suction pipe 31 is provided with an air cushion 34 to better contact the mirror surface and enhance the dust collection effect.

[0048] like Figure 2 As shown, the pushing mechanism 4 includes a scraper 40 and two mechanical arms 41. The two mechanical arms 41 are respectively located on the left and right sides of the top of the air suction pipe 31. The upper ends of the two mechanical arms 41 are respectively fixedly connected to the two side ends of the air suction pipe 31, and the lower ends of the two mechanical arms 41 are respectively movably connected to the two ends of the scraper 40. The lower end of the scraper 40 is bonded with an anti-scratch strip. By adjusting the mechanical arm 41 to drive the movement of the scraper 40, the lower end of the scraper 40 is attached to the mirror surface, and large garbage and debris such as leaves and pebbles on the heliostat can be pushed out of the heliostat in advance, which provides convenience for subsequent dust collection and water washing. The lower end of the scraper 40 is bonded with an anti-scratch strip to prevent the mirror surface from being scratched during the pushing process.

[0049] like Figure 3 , Figure 7 As shown, the wind blowing mechanism 5 includes a shell, and a fan blade 51 is arranged inside the shell. The fan blade is rotated by a wind blowing motor arranged in the shell, and a plurality of air outlets 52 are arranged on the top of the shell. By turning on the wind blowing button, the wind blowing motor in the shell is started to rotate, driving the rotation of the fan, and ventilation can be provided from top to bottom. A low-power fan is arranged thereon to dry the water left by the previous processes, so as to prevent watermarks from being left after cleaning and affecting the cleanliness of the mirror surface.

[0050] like Figure 2 , Figure 3As shown, the detection module 7 includes a first ultrasonic sensor 70 arranged on the mechanical arm 41 and a second ultrasonic sensor 71 arranged at the lower edge of the top of the shell. Ultrasonic sensors are respectively arranged at the front and rear ends of the overall cleaning device, and both groups are facing downward to detect whether the cleaning device moves to the edge of the mirror. A distance threshold is preset in the control unit. When the cleaning device moves to the edge of the mirror, the ultrasonic sensor receives the signal, converts the physical signal into an electrical signal, and transmits it to the control unit. After the signal is detected, the switch of the current operating mechanism is turned off, so that the cleaning device stops rolling and cleaning.

[0051] like Figure 2 , Figure 8 As shown, the pushing mechanism 4 also includes a remote controller, each mechanical arm 41 includes an upper mechanical arm 41a and a lower mechanical arm 41b that are hinged to each other, a box 42 and a steering gear 43 are arranged between the lower mechanical arm 41b and the scraper 40, the upper mechanical arm 41a is connected to the air suction pipe 31, the box 42 is fixedly connected to the bottom end of the lower mechanical arm 41b, the fuselage part of the steering gear 43 is fixedly arranged in the box 42, the rudder blade part of the steering gear 43 extends out of the box 42 and is connected to one end of the scraper 40, the box 42 is provided with a third ultrasonic sensor 44, the third ultrasonic sensor 44 is connected to the input end of the control unit, and the remote controller communicates with the steering gear 43 wirelessly. The distance to the mirror surface is continuously detected by the third ultrasonic sensor 44, and the steering gear 43 is controlled by the remote controller, and the rudder blade on the steering gear 43 drives the movement of the scraper 40, thereby controlling the contact area and angle between the scraper 10 and the mirror surface to better clean the mirror surface.

[0052] like Figure 2 As shown, a handle 35 is provided on the outer surface of the extraction box 33, and a clamping plate 36 for clamping the scraper 40 is provided at the top of the suction pipe 31. The clamping plates 36 are provided in two groups, symmetrically arranged at both ends of the top of the suction pipe 31. The setting of the handle 35 further facilitates the dumping of the sundries in the extraction box, and the scraper 40 can be clamped on the clamping plates 36 when the work is finished, without taking up space.

[0053] Specifically, the control unit is a single chip microcomputer, the input end of the control unit is provided with a connected main switch, and the output end of the control unit is connected to the water washing motor, the wiping motor, the dust suction motor, the wind blowing motor and the rolling motor through a relay. The water washing mechanism and the rolling mechanism can be controlled by a total relay, and the initial state is normally closed. When in use, the main switch is turned on, the rotating brush 13 starts to start, the rolling mechanism 7 starts after a delay, and the water pump 15 starts to pump water after another delay. The pumping rate of the water pump 15 can be set in the internal program, and then cleaning can be carried out.

[0054] Regarding the problem of gap-driven heliostats generated during the splicing process, the frequency of the ultrasonic sensor is set according to the actual situation, the number of gaps between two heliostats in a row of heliostats and the estimated speed of a mirror. When a gap is reached, the distance is compared and then counted. The distance is accumulated to the initially set threshold (the threshold is the distance between the ultrasonic sensor and the edge of the mirror). When the cleaning device moves to the edge of the last mirror, the counting stops and a signal is sent to the main switch. After collecting the signal, the motor connected to the relay is turned off, and then the related movement mechanism is turned off.

[0055] Cleaning process: pushing mechanism, dust suction mechanism, water washing mechanism, wiping mechanism, wind blowing mechanism. In winter, considering that water washing is easy to freeze, the water washing mechanism may not be implemented. There is no specific restriction on the implementation process of the present invention, and the cleaning process can be selected according to actual needs. When cleaning, it is first necessary to keep the mirror surface of the heliostat horizontal, and then transport the heliostat cleaning device to the mirror surface of the heliostat that needs to be cleaned by the elevator. After completing the cleaning of one row of heliostats, the cleaning device is transferred to the mirror surface of the next row of heliostats, and the mirror surface of the heliostat is cleaned by manually controlling the various mechanisms of the device. The device has a simple structure and can clean the mirror surface of the heliostat in the desert or Gobi, thereby ensuring that the reflection efficiency of the heliostat will not be affected by the mirror surface being covered with gravel and dust.
