One end of the No. 1 screw rod 3014 penetrates the water receiving box 3011 and extends a part thereof, and a worm gear 3016 is fixedly connected to the No. 1 screw rod 3014.

[0032] The moving assembly 302 includes two groups of No. 1 fixed plates 3021 and No. 2 fixed plates 3022, and the No. 1 fixed plates 3021 and No. 2 fixed plates 3022 are fixedly connected to the nozzle 402 and the water receiving box 3011 respectively. The two groups of No. 1 fixed plates 3021 and No. 2 fixed plates 3022 are rotatably connected with No. 2 screw rods 3023 and guide rods 3025 respectively. One side of the No. 1 fixed plate 3021 is fixedly connected with a motor 3024, and the motor 3024 is a prior art and will not be described in detail here. The two ends of the No. 2 screw rod 3023 respectively penetrate the No. 1 fixed plate 3021 and the No. 2 fixed plate 3022, and one end of the No. 2 screw rod 3023 is fixedly connected to one end of the motor 3024, and the other end of the No. 2 screw rod 3023 is provided with a snail pattern 3026, and the snail pattern 3026 is meshed with the worm wheel 3016.

[0033] The wiping assembly 303 includes two sliders 3031, and the two sliders 3031 are respectively threadedly connected and slidably connected to the second screw rod 3023 and the guide rod 3025, a mounting plate 3032 is fixedly connected between the two sliders 3031, and a plurality of rotating rods 3033 are rotatably connected to the mounting plate 3032, both ends of the rotating rods 3033 pass through the mounting plate 3032 and extend a portion, a sponge 3034 is fixedly connected to the bottom of the rotating rod 3033, and the bottom of the sponge 3034 is flush with the bottom of the photovoltaic panel, and the plurality of rotating rods 3033 are connected to each other through a transmission member 3035, and the transmission member 3035 is composed of a pulley and a belt.

[0034] The transmission assembly 304 includes a U-shaped plate 3041, both ends of which are fixedly connected to the nozzle 402 and the water receiving box 3011 respectively, a rack 3042 is fixedly connected to one side of the U-shaped plate 3041, and a gear 3043 is fixedly connected to the sidemost rotating rod 3033 among the multiple rotating rods 3033, and the gear 3043 is meshed with the rack 3042.

[0036] When it rains, rainwater on the photovoltaic panels will flow along the photovoltaic panels to the water receiving box 3011, and the water in the water receiving box 3011 will enter the water tank 401 through the connecting pipe 3013 for storage, and be used for cleaning the photovoltaic panels when it is not raining.

[0037] When it rains, the sprinkler 402 does not need to spray water. At this time, the starter motor 3024 drives the No. 2 screw rod 3023 to rotate.

[0038] At the same time, when the second screw rod 3023 rotates, the slider 3031 will move accordingly, and the movement of the slider 3031 will move the rotating rod 3033 and the sponge 3034. When the sponge 3034 moves, it will wipe the photovoltaic panel. As the rotating rod 3033 moves, the gear 3043 will move relative to the rack 3042, so the gear 3043 will rotate accordingly, and then rotate with the rotating rod 3033, which is beneficial to the cleaning of the photovoltaic panel.

[0039] When it is not raining, the nozzle 402 can be directed to spray water at the photovoltaic panel, and the photovoltaic panel can be cleaned using the above method.
