Rainwater pours down from water outlet 3, and directly falls into rainwater collecting bucket 4. The lower part of rainwater collecting bucket 4 is connected with a water storage tank through a specially laid pipeline, so that the collected rainwater is continuously transported to water storage tank 18 for storage.

[0028] The upper portion of the rainwater collecting bucket 4 is provided with a filtering assembly, which comprises a connecting plate 5, the two ends of the connecting plate 5 are respectively provided with a first filter screen 6 and a second filter screen 7, the pore size of the filter screen is accurate enough to filter sand and stones, and specific limitations are not made, the lower portion of the connecting plate 5 is provided with a first motor 8, the output shaft of the first motor 8 is fixedly connected with the middle portion of the connecting plate 5, the first filter screen 6 is located directly above the rainwater collecting bucket 4, the upper portion of the second filter screen 7 is provided with a cleaning assembly, the cleaning assembly comprises a second motor 13, the output shaft of the second motor 13 is fixedly connected with a rotating plate 14, and the rotating plate 14 is provided with a cleaning brush 15. The first motor 8 can drive the connecting plate 5 to rotate, so that the first filter screen 6 and the second filter screen 7 work alternately, when the first filter screen 6 needs to be cleaned due to more impurities, the second filter screen 7 can be rotated to the upper portion of the rainwater collecting bucket to work, thereby ensuring the continuity of the filtering work. Although the filtering effect of rainwater will be lost at the moment of rotation, it can be ignored because the time is very short. When the second motor 13 is started, the output shaft drives the rotating plate 14 to rotate, and the cleaning brush 15 on the rotating plate 14 rotates to clean the surface of the filter screen, so that the impurities and dirt remaining on the filter screen are cleaned away, and the filter screen always maintains good filtering effect.

[0029] The bottom of the water storage tank 18 is provided with a first drain pipe 901, the first drain pipe 901 is provided with a first water pump 1001, the tail end of the first drain pipe 901 is communicated with the water spraying pipe 11 arranged along the upper edge of the photovoltaic panel 1, and a plurality of nozzles 12 are arranged on the water spraying pipe 11 in the horizontal direction. When the photovoltaic panel 1 needs to be cleaned, the first water pump 1001 is started, the water in the water storage tank 18 is conveyed to the water spraying pipe 11 through the first drain pipe 901, and then sprayed out through each nozzle 12, so that the surface of the photovoltaic panel 1 is washed, thereby effectively removing the dust and impurities on the surface of the photovoltaic panel 1, and ensuring the power generation efficiency of the photovoltaic panel.

[0030] The bottom of the water storage tank 18 is provided with a second drain pipe 902, the second drain pipe 902 is provided with a second water pump 1002, and the tail end of the second drain pipe 902 is connected with a water using system.

[0032] Embodiment 2

[0033] The basic structure is the same as that of Embodiment 1, as shown in Figures 3-4 The difference is that a collecting cylinder 19 is arranged above the rainwater collecting bucket 4 and between the water outlet 3 and the rainwater collecting bucket 4, and the control system includes a PLC controller and a liquid level sensor, the liquid level sensor is arranged on the inner wall of the collecting cylinder, and the PLC controller is electrically connected with the first motor, the second motor and the third water pump. Its function is to monitor the liquid level in the collecting cylinder in real time. When the liquid level sensor detects that the liquid level in the collecting cylinder reaches a certain height, it will transmit a signal to the PLC controller. The PLC controller controls the start and stop of the first motor, the second motor and the third water pump according to the preset program, and realizes the automatic control of the filtering assembly and the cleaning assembly. Specifically, when the liquid level in the collecting cylinder rises, that is, the speed of the rainwater flowing into the collecting cylinder is greater than the speed of the rainwater flowing out, it represents that the filter screen is blocked. At this time, the PLC controller sends a signal to control the first motor to rotate and complete the alternation of the filter screen, controls the second motor to rotate and completes the cleaning of the replaced filter screen, and controls the third water pump to start. Water is sprayed at the nozzle to complete the flushing of the filter screen.

[0034] The gap between the collecting cylinder and the rainwater collecting bucket is the same as the thickness of the first filter screen and the second filter screen. After the first filter screen and the second filter screen rotate, they can be tightly embedded in the gap, which not only ensures the stability of the installation of the filtering assembly, but also avoids the overflow of rainwater due to the too large gap. The water flow sensor is arranged on the pipeline between the rainwater collecting bucket and the water storage tank. The water flow sensor can monitor the water flow in the pipeline in real time, such as the size of the water flow and whether there is water flow through the pipeline. These data can also be transmitted to the PLC controller, which provides an important basis for the operation state monitoring and fault diagnosis of the entire device.

[0035] In addition, the above-mentioned motors, collecting cylinders and other components have corresponding supports, which are not shown in the figure.

[0036] Finally, it should be pointed out that the above embodiments are only used to illustrate the technical solutions of the present application, and are not limited thereto. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent replacement to part or all of the technical features. The modification or replacement does not make the essence of the corresponding technical solution deviate from the scope of the technical solutions of the embodiments of the present application.
