Abstract
Description
A solar panel cleaning and protection device Technical Field
[0001] This utility model relates to the field of cleaning equipment technology, and more specifically, to a solar panel cleaning and protection device. Background Technology
[0002] The efficiency of a solar photovoltaic (PV) power generation system is directly affected by the cleanliness of the PV module surface. Contaminants such as dust, bird droppings, sand, and snow significantly reduce the light transmittance of solar panels, leading to a decrease in photoelectric conversion efficiency. Studies have shown that in dusty areas, uncleaned solar panels can reduce efficiency by 15%-30%, or even more. Therefore, regularly cleaning solar panels is essential to maintaining their optimal power generation performance.
[0003] Based on the above, the inventors have discovered that the cleaning of solar panels currently relies mainly on manual cleaning. Common methods include high-pressure water gun washing and manual wiping. High-pressure water gun washing requires a large amount of water and may damage the panels due to excessive water pressure. Manual cleaning by workers using mops, soft cloths, or brushes is not only labor-intensive but also extremely inefficient, making it difficult to cover large-area photovoltaic arrays. Especially for large photovoltaic power plants, the cleaning cycle is long, affecting power generation revenue. Therefore, in view of this, the inventors have researched and improved the existing structure to provide a solar panel cleaning and protection device, aiming to achieve a more practical purpose. Summary of the Invention
[0004] 1. Technical problems to be solved
[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a solar panel cleaning and protection device. It can use a guide mechanism to install the mounting frame onto the photovoltaic panel and connect the water pipe to an external water source. Through the action of the water spraying mechanism, water is sprayed onto the surface of the photovoltaic panel. The servo motor drives the walking wheels, so that the mounting frame can drive the rotating roller brush to move on the photovoltaic panel. During the movement, the roller brush can clean the surface of the photovoltaic panel. The automation level of the entire operation is improved, manual intervention is reduced, and cleaning efficiency is greatly improved.
[0006] 2. Technical Solution
[0007] To solve the above problems, the present invention adopts the following technical solution.
[0008] A solar panel cleaning and protection device includes a mounting frame located on top of a photovoltaic panel. A roller brush is rotatably connected between the inner walls of both ends of the mounting frame. Mounting grooves are provided at the bottom of both ends of the mounting frame, and two traveling wheels are rotatably connected in the mounting grooves via pins. Servo motors are mounted on both ends of the mounting frame, and the output shafts of the servo motors are connected to the shaft ends of the corresponding traveling wheels via couplings. Guide mechanisms are provided between both ends of the mounting frame and the photovoltaic panel.

[0009] Furthermore, a drive motor is mounted on one end of the mounting bracket, and the output end of the drive motor is connected to the shaft end of the roller brush via a coupling.
[0010] Furthermore, the guiding mechanism includes a fixed frame fixed to the end of the mounting bracket, and two symmetrically arranged transverse guide wheels are rotatably mounted on the bottom of the fixed frame, and the transverse guide wheels are movably connected to the outer side of the photovoltaic panel. A vertical guide wheel is rotatably mounted on the outer side of the fixed frame.
[0011] Furthermore, the water spraying mechanism includes a water spraying pipe fixed to the inner wall of the mounting frame, one end of the water spraying pipe being fixed and connected to a connecting pipe, and one end of the connecting pipe being connected to one end of the water distribution pipe through a control valve.
[0012] Furthermore, the bottom of the water spray pipe has several water outlet holes, and these water outlet holes are arranged in a matrix.

[0014] 3. Beneficial effects
[0015] Compared with existing technologies, the advantages of this utility model are:

Simultaneously, the water supply pipe is connected to an external water source, and the control valve is opened, allowing water to be sprayed from the spray nozzles on the water pipe onto the surface of the photovoltaic panel for rinsing. A servo motor drives the walking wheels, enabling the mounting bracket to move a rotating roller brush on the photovoltaic panel.
