Referring to fig. 2, in the present embodiment, the filter box 800 includes a box 810 and a filter screen 820 disposed inside the box 810, specifically, the cleaning pipe 510 is connected to the box 810, and the filter screen 820 separates an inner cavity of the box 810 from a pipe cavity of the water pipe 520.

This distributed photovoltaic panel surface cleaning device is in the use, and the inside rivers of water storage box 400 get into clean pipe 510, along with dust removal brush 200 is to going on of photovoltaic board scrubbing work, and dust and the impurity on photovoltaic panel surface get into clean pipe 510 through soaking the hole in, flow to box 810 along with the rivers in the clean pipe 510 together. After the water pump 900 is started, under the action of the power of the water pump 900, the water mixed with impurities in the box 810 moves towards the direction of the water pipe 520, in the process that the water enters the water pipe 520, the water is filtered by the filter screen 820, the impurities in the water are filtered in the box 810 by the filter screen 820, and the clean water flows along the water pipe 520 to the water inlet pipe 530 and then enters the water storage tank 400.

The arrangement form of the filter box 800 has simple structure and is easy to process and manufacture.

It should be noted that a box door may be reserved in the box 810, so that the filter box 800 is maintained after impurities in the box 810 are accumulated to a certain degree.

Referring to fig. 2, in the present embodiment, a driving blade 830 may be disposed inside the box 810. Through set up drive fan blade 830 in box 810, can play certain stirring effect to the rivers in the box 810, accelerate the filtration efficiency of filter screen 820 to rivers.

Referring to fig. 2, in the embodiment, a floating plate 410 is disposed inside the water storage tank 400, and an alarm element 420 is further installed on the water storage tank 400, wherein the floating plate 410 is electrically connected to the alarm element 420.

As the amount of water in the reservoir 400 gradually decreases, the float plate 410 is driven to move downward. When the floating plate 410 descends to the set height position, the alarm element 420 is triggered, the alarm element 420 is used for giving an alarm to a worker, the worker is reminded of storing water in the water storage tank 400, and adverse effects on cleaning operation of the photovoltaic plate due to insufficient water in the water storage tank 400 are avoided.

In this embodiment, the alarm element 420 may alarm in an audible and visual alarm manner.

It should be noted that, in this embodiment, an insulating component may be disposed at a connection between the alarm element 420 and the water storage tank 400, so as to prevent the water flow in the water storage tank 400 from being electrified due to electric leakage of the alarm element 420, thereby affecting normal operation of the distributed photovoltaic panel.

The working principle of the distributed photovoltaic panel surface cleaning device is as follows.

When the device is used, the distributed photovoltaic panel surface cleaning device can be placed below the distributed photovoltaic panel, namely the distributed photovoltaic panel is positioned above the long bevel edge of the supporting seat 120; then, the turntable 320 is rotated, and in the rotating process of the turntable 320, the driving rod 330 drives the moving plate 340 to reciprocate along the length direction of the cleaning tube 510, so as to drive the dust removing brush 200 to clean the surface of the distributed photovoltaic panel; meanwhile, water flow in the water storage tank 400 enters the cleaning pipe 510, and constantly wets the dust removal brush 200 through the infiltration holes formed in the cleaning pipe 510, so that the cleaning effect on the distributed photovoltaic panel is enhanced; in the process of cleaning the distributed photovoltaic panel by the reciprocating motion of the dust removing brush 200, dust and impurities on the surface of the distributed photovoltaic panel enter the cleaning pipe 510 through the infiltration holes and enter the box body 810 of the filter box 800 along with water flow; the fan blades 830 are driven to rotate the impurities to the filter screen 820, and meanwhile, the water pump 900 sends water flow processed by the fan blades 830 to the water inlet pipe 530 through the water conveying pipe 520. In the process, the water level in the water storage tank 400 continuously drops to drive the floating plate 410 to move downwards, and the alarm element 420 is triggered after the floating plate 410 moves downwards to the set height position, so that the aims of quickly and continuously cleaning the distributed photovoltaic panel and timely reminding workers of replacement when the cleaning water is insufficient are fulfilled.

In the process of reciprocating the moving plate 340, the pressing plate 640 is driven to intermittently press the elastic air bag 610 arranged on the fixed frame 130, when the elastic air bag 610 is pressed, air in the inner cavity of the elastic air bag is sent into the exhaust pipe 630, and the heating element 700 in the exhaust pipe 630 heats the air and then sends the air into the cleaning pipe 510; when the elastic air bag 610 is rebounded, the air in the outside is absorbed through the air inlet pipe 620, so that the purpose of rapidly drying the surface of the distributed photovoltaic panel in rainy and snowy weather or after conventional cleaning is achieved.
