[0004] However, existing photovoltaic panels cannot effectively clean their surfaces during cleaning, thus failing to provide adequate protection. Therefore, there is an urgent need in the market for a photovoltaic panel protection device for microgrid photovoltaic power generation to solve these problems. Utility Model Content

[0005] The purpose of this utility model is to provide a photovoltaic panel protection device for microgrid photovoltaic power generation, so as to solve the problem mentioned in the background art that the surface of the existing photovoltaic panels cannot be cleaned well during cleaning, thus failing to provide adequate protection for the photovoltaic panels.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A protective device for photovoltaic panels used in microgrid photovoltaic power generation includes a mounting frame, a support frame mounted on one side of the mounting frame, a photovoltaic panel mounted on one side of the support frame, limit frames mounted at both ends of the photovoltaic panel, a fixing frame mounted on one side of the photovoltaic panel, mounting plates mounted on both sides of the fixing frame, a movable seat mounted on the outside of the fixing frame, a water spray device mounted on one side of the movable seat, a motor mounted on one end of the outer wall of the mounting plate, a connecting frame mounted on one side of the inner wall of the mounting plate, and a moving wheel mounted below the connecting frame.

Then, under the action of gravity, the water flows down and lands on the surface of the photovoltaic panel.

[0015] Furthermore, a control device is installed on the top of the fixing frame, and a fixing foot is provided at the lower end of the control device. The fixing foot is fixedly connected to the fixing frame by fixing screws, and a control box is installed on one side of the control device.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] (1) This utility model connects to clean water through the water inlet, so that clean water is sprayed from the water spraying device. Under the action of gravity, the clean water flows down to the surface of the photovoltaic panel. Then, by turning on the motor, the active wheel can drive the driven wheel to rotate, so that the moving wheel can drive the fixed frame to move along the direction of the limiting groove. At the same time, by turning on the second motor, the cleaning roller can rotate, and the cleaning brush can effectively clean the surface of the photovoltaic panel. This can effectively protect the photovoltaic panel and prevent a large amount of dust from falling on the surface of the photovoltaic panel, thereby affecting the performance of the photovoltaic panel.

[0023] (2) By setting a limiting frame, the present invention has a limiting groove inside the limiting frame.

A cleaning roller 16 is installed between the two mounting plates 5. A cleaning brush 17 is installed on the outside of the cleaning roller 16. The photovoltaic panel 2 can be easily installed through the mounting frame 1 and the support frame 101. Clean water is sprayed by the water spraying device 10 and then allowed to flow, so that the clean water can flow to the surface of the photovoltaic panel 2, which can easily clean the surface of the photovoltaic panel 2. It should be noted that, in order to save space and highlight the innovative elements of this patent, such as the specific working principle and working process of the photovoltaic panel, it will not be described in detail in this patent.

[0031] See Figure 1 , Figure 2 and Figure 3The movable base 8 and the fixed frame 4 are fixedly connected by a fastening knob 9. The upper end of the water spraying device 10 is provided with a water inlet 1001. The control device 6 is installed on the upper part of the fixed frame 4.
