Meanwhile, the second moving gear 6112 is prevented from being meshed with the rectangular annular rack 609 in the moving process, so that the movement reliability of the cleaning roller 613 is not affected. When the gear is moved, the baffle 6101 abuts against the rectangular bump 6135, and the mounting housing 6132 does not rotate, so that the first moving gear 6111 can drive the inclined roller and the moving assembly to advance through the engagement motion with the linear rack 602.

When the cleaning and spraying device is used, on one hand, the electromagnetic valve 51 can be opened through the control system 2 with the built-in timing module 7 in a timing mode, the water supply pump 52 is started, the cleaning and spraying head 4 sprays a fan-shaped water curtain to wash dust on the surface of the photovoltaic module 3, and on the other hand, the control system 2 can be triggered after the dust detection device 1 detects that the dust on the surface of the photovoltaic module 3 reaches a certain area, so that the cleaning and spraying head 4 is started to spray water for cleaning. After the cleaning sprinkler 4 is cleaned, the control system 2 checks the cleaning effect through the dust detection device 1, and stops cleaning if the photovoltaic module 3 is cleaned, otherwise triggers the operation of the intensified cleaning mechanism 6.
After the dust detection device 1 sends the collected signal containing the dirt to the control system 2, the control system 2 can identify the position of the dirt, convert the position of the dirt into a related control signal and send the related control signal to the strengthening cleaning mechanism 6 to control the operation of the strengthening cleaning mechanism. When the intensive cleaning mechanism 6 operates, the moving motor 6133 operates to drive the moving gear 611 and the annular roller body 6131 to rotate, bristles on the surface of the annular roller body 6131 roll and brush on the photovoltaic module 3, the moving gear 6111 rotates to drive the moving module to slide forwards along the rail 601, namely, the moving module moves towards one side of the lower portion of the photovoltaic module 3, and the water sprayer 607 which is started at the same time performs powerful washing on the front of the cleaning roller 613 through the high-pressure spray nozzle 6072, so that the moving and the cleaning are performed synchronously. Because the spray head is adopted for targeted high-pressure washing, and the washing function of the annular roller body 6131 is matched, the dirt washing capability is greatly enhanced, and some dirt and dust which are not easy to be washed by the fan-shaped water curtain can be washed away.
When a dirt position is reached which has not been washed away before, the brake 612 is activated to clamp the rail 601 to stop the moving assembly from being fixed to the rail 601. At this time, as the moving assembly stops, the first moving gear 6111 overcomes the block of the elastic assembly 610 when continuing to advance, when the rectangular bump 6135 is reached to be attached to the front side of the constraint frame 608, the second moving gear 6112 is engaged with the rectangular annular rack 609, so that the cleaning roller 613 starts to move around up and down along the rectangular annular rack 609, and when the cleaning roller 613 falls, the cleaning roller is advanced and brushed through the engagement of the first moving gear 6111 and the linear rack 602, so that repeated brushing can be performed at the dirt position.
Moreover, when the cleaning roller 613 ascends or descends, the portion of the two ends of the mounting housing 6132 exposed from the annular roller body 6131 presses against the L-type rotating plate through the water spraying swinging mechanism 606, so that the L-type rotating plate swings forward, the L-type rotating plate swings forward through the transmission connecting plate 6063, the rotating mounting plate 6061 swings forward and upward, the water column sprayed by the high-pressure spray head 6072 swings accordingly, the water column passes through the cleaning roller 613 and then washes the dirt below the lifted cleaning roller 613, then the water sprayer 607 swings in the opposite direction when the cleaning roller 613 falls, the water column sprayed by the high-pressure spray head 6072 also swings from below the cleaning roller 613 to the position direction of the front cleaning roller 613, the washing direction of the water column is changed back and forth while the cleaning roller 613 moves, the dirt below the cleaning roller 613 is washed at high pressure, and the probability of washing the dirt is further improved.
When the moving assembly moves back and up, since the moving gear 611 does not move down further, the moving assembly can directly move back without being affected by the rectangular ring-shaped rack 609. But also can be processed into a toothless part at the position where teeth are easy to be punched in order to reduce the tooth punching or clamping phenomenon, thereby avoiding loss.
The invention is described above with reference to the accompanying drawings, it is obvious that the specific implementation of the invention is not limited by the above-mentioned manner, and it is within the scope of the invention to adopt various insubstantial modifications of the inventive concept and solution of the invention, or to apply the inventive concept and solution directly to other applications without modification.
