Technical Field
[0001] This utility model relates to the field of photovoltaic panel cleaning and dust removal devices, and in particular to a photovoltaic panel cleaning and dust removal device. Background Technology
[0002] With the global trend of energy structure transitioning towards clean energy, photovoltaic (PV) power generation, as an important form of renewable energy utilization, is experiencing rapid and continuous growth in installed capacity. As the core component of a PV power generation system, the surface cleanliness of the PV panel directly affects its photoelectric conversion efficiency. However, PV panels are typically installed in open outdoor areas and are exposed to the natural environment for extended periods, making them highly susceptible to the adhesion of pollutants such as dust, sand, bird droppings, and leaf debris. These pollutants form a shading layer on the PV panel surface, hindering sunlight from directly reaching the internal solar cells, reducing light absorption, and consequently significantly decreasing photoelectric conversion efficiency. Related data shows that when the dust thickness on the PV panel surface reaches a certain level, its power generation efficiency can decrease by 10%-30%, severely impacting the overall power generation and economic benefits of the PV power generation system. Furthermore, long-term adhesion of acidic or alkaline pollutants to the PV panel surface can also corrode the glass cover, shortening the PV panel's lifespan.
[0003] Traditional methods for cleaning photovoltaic panels mainly include manual sweeping and high-pressure water gun washing. Manual sweeping is not only labor-intensive and inefficient, requiring a large investment of manpower, but also makes it difficult to ensure the safety of workers during the cleaning process. Although high-pressure water gun washing is relatively fast, it is easy to damage the surface of photovoltaic panels due to improper water pressure control, and it also consumes a lot of water resources, which is inconsistent with the development concept of energy conservation and environmental protection and cannot meet the cleaning needs of photovoltaic panels of different specifications.
[0004] Therefore, it is necessary to provide a photovoltaic panel cleaning and dust removal device to solve the above-mentioned technical problems. The information disclosed in this background section is only intended to enhance the understanding of the overall background of this utility model, and is not necessarily to be regarded as an admission or to imply in any way that the information constitutes prior art known to those skilled in the art. Utility Model Content
[0005] This utility model provides a photovoltaic panel cleaning and dust removal device, which solves the technical problems of traditional manual cleaning, which is not only labor-intensive and inefficient, requiring a large investment of manpower, but also makes it difficult to ensure the safety of workers during the cleaning process. Although high-pressure water gun washing is relatively fast, it is easy to damage the surface of photovoltaic panels due to improper water pressure control, and it also consumes a lot of water resources, which is not in line with the development concept of energy conservation and environmental protection, and it is difficult to meet the cleaning needs of photovoltaic panels of different specifications.
[0006] To solve the above-mentioned technical problems, this utility model provides a photovoltaic panel cleaning and dust removal device, including a U-shaped mounting plate. Waterproof stepper motors are installed on both sides of the upper end of the U-shaped mounting plate. A rotating shaft is installed at the output end of each waterproof stepper motor.

Soft brushes are installed in a ring around the bottom of the brush disc from the inside out. A micro water pump is installed at the top of the U-shaped mounting plate. A water outlet pipe is connected to the left side of the micro water pump. A conveying pipe is connected to the side of the water outlet pipe away from the micro water pump, passing through the bottom of the U-shaped mounting plate. Spray pipes are connected to the front and rear sides of the conveying pipe. Adjustable universal spray heads are connected sequentially from left to right at the bottom of the spray pipes. An elastic water inlet pipe is connected to the right side of the micro water pump. A support block is installed on the rear side of the U-shaped mounting plate. A telescopic adjustment rod is installed on the rear side of the top of the support block.
[0007] Preferably, the bottom of the micro water pump is equipped with a mounting bracket, and the bottom of the mounting bracket is fixed to the top of the U-shaped mounting plate.

[0012] Compared with related technologies, the photovoltaic panel cleaning and dust removal device provided by this utility model has the following beneficial effects:
[0013] This utility model provides a photovoltaic panel cleaning and dust removal device. The bottom of the brush plate is designed with soft bristles, which are soft and have good elasticity. During the cleaning process, they can closely adhere to the surface of the photovoltaic panel, while avoiding scratching and damage to the glass cover of the photovoltaic panel. This effectively protects the surface structure and service life of the photovoltaic panel. The handles installed on both sides of the telescopic adjustment rod are covered with anti-slip sleeves, which can increase the friction between the operator's hand and the handle, preventing the device from falling off due to hand slippage during the cleaning process.

The waterproof stepper motor has good waterproof performance and can adapt to complex environments such as outdoor humidity and rainy days, preventing short circuit failure of the motor due to water ingress. The bearing seat sleeved on the surface of the rotating shaft not only improves the rotational stability of the rotating shaft and reduces friction loss, but also provides a certain degree of protection for the rotating shaft and extends its service life.

Detailed Implementation
[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0022] Example 1:
[0023] Please see Figure 1-5This utility model provides a technical solution: a photovoltaic panel cleaning and dust removal device, including a U-shaped mounting plate 1, waterproof stepper motors 2 are installed on both sides of the upper end of the U-shaped mounting plate 1, a rotating shaft 3 is installed at the output end of the waterproof stepper motor 2, the bottom of the rotating shaft 3 passes through both sides of the bottom of the U-shaped mounting plate 1, a brush plate 4 is installed at the bottom of the rotating shaft 3, a soft brush 5 is installed in a ring from the inside to the outside at the bottom of the brush plate 4, a micro water pump 6 is set at the top of the U-shaped mounting plate 1, a water outlet pipe 7 is connected to the left side of the micro water pump 6, a conveying pipe 8 is connected to the bottom of the U-shaped mounting plate 1 on the side of the water outlet pipe 7 away from the micro water pump 6, a spray pipe 9 is connected to the front and rear sides of the conveying pipe 8, an adjustable universal nozzle 10 is connected to the bottom of the spray pipe 9 from left to right, an elastic water inlet pipe 11 is connected to the right side of the micro water pump 6, a support block 12 is installed on the rear side of the U-shaped mounting plate 1, and a telescopic adjustment rod 13 is installed on the rear side of the top of the support block 12.
[0024] In this implementation scheme, the waterproof stepper motor 2 drives the rotating shaft 3 to rotate the brush plate 4. The soft brush 5 arranged in a ring from the inside to the outside at the bottom of the brush plate 4 can wipe and clean the surface of the photovoltaic panel in an all-round and thorough manner, effectively removing various pollutants such as dust, sand, and bird droppings attached to the surface. At the same time, the micro water pump 6 delivers water to the spray pipe 9 through the water outlet pipe 7 and the delivery pipe 8, and then sprays it evenly on the surface of the photovoltaic panel through the adjustable universal nozzle 10, forming a "spraying + brushing" synergistic cleaning mode, which not only enhances the cleaning effect, but also avoids the scratches and damage to the surface of the photovoltaic panel caused by dry brushing.
[0025] Example 2:
[0026] Please see Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: a mounting bracket is installed at the bottom of the micro water pump 6, and the bottom of the mounting bracket is fixed to the top of the U-shaped mounting plate 1. A bearing seat is fitted on the surface of the rotating shaft 3, and the top of the bearing seat is fixed to both sides of the bottom of the U-shaped mounting plate 1. The two sides of the spray pipe 9 are fixed to the front sides of the two sides of the bottom of the U-shaped mounting plate 1 and the rear sides of the bottom. Handles are installed on the rear sides of both sides of the telescopic adjustment rod 13, and anti-slip sleeves are fitted on the surface of the handles. Fixing buckles that cooperate with the elastic water inlet pipe 11 are installed on the front and rear sides of the right side of the telescopic adjustment rod 13. A water inlet 14 is provided in a ring shape from the inside to the outside of the top of the brush plate 4, and the bottom of the water inlet 14 extends to the bottom of the brush plate 4.
[0027] In this embodiment: the telescopic adjustment rod 13 can be flexibly adjusted according to the height of the operator and the installation height and tilt angle of the photovoltaic panel, making it convenient for the operator to stand on the ground or in a suitable position to carry out cleaning work without having to climb to the top of the photovoltaic panel support, reducing the difficulty of operation and safety risks. The fixing buckle set on the surface of the telescopic adjustment rod 13 can fix the elastic water inlet pipe 11, preventing the elastic water inlet pipe 11 from shaking and getting tangled during the movement of the device, ensuring the smooth progress of the cleaning operation.
[0028] The working principle of the photovoltaic panel cleaning and dust removal device provided by this utility model is as follows:
[0029] Implementation steps for the first innovation point:
[0030] Step 1: First, adjust the telescopic length of the telescopic adjustment rod 13 to make the device reach a suitable operating height. Then, connect the free end of the elastic water inlet pipe 11 to an external water source such as a tap or water storage tank to ensure a stable water supply.
[0031] Step 2: The operator holds the handles on both sides of the telescopic adjustment rod 13 and moves the device to the starting position of the photovoltaic panel to be cleaned, so that the soft brush 5 at the bottom of the brush plate 4 contacts the surface of the photovoltaic panel. Then, the waterproof stepper motor 2 and the micro water pump 6 are started. After the waterproof stepper motor 2 is started, its output end drives the rotating shaft 3 to rotate at a constant speed. The rotating shaft 3 then drives the brush plate 4 to rotate synchronously. During the rotation, the soft brush 5 at the bottom of the brush plate 4 wipes and cleans the contaminants on the surface of the photovoltaic panel. After the micro water pump 6 is started, it draws in water from the external water source and pressurizes it.
[0032] Step 3: Pressurized water is delivered to the delivery pipe 8 through the outlet pipe 7 on the left side of the micro water pump 6. The delivery pipe 8 then distributes the water to the front and rear spray pipes 9. Finally, the water is sprayed evenly onto the photovoltaic panel surface through the adjustable universal nozzles 10 arranged from left to right at the bottom of the spray pipes 9. The water is then delivered to the soft brush 5 of the brush plate 4 through the water inlet 14. Under the synergistic effect of "spraying + brushing", the pollutants on the surface of the photovoltaic panel are quickly moistened, loosened and removed by the soft brush, achieving a cleaning effect.
[0033] Implementation steps for the second innovation point:
[0034] Step 1: During the operation of the device, the operator slowly moves the device by holding the telescopic adjustment rod 13, so that the brush plate 4 and the spray pipe 9 can move at a constant speed along the length or width of the photovoltaic panel surface, ensuring that every area of the photovoltaic panel surface can be thoroughly cleaned and avoiding cleaning dead corners.
[0035] Step 2: During the movement, the operator can adjust the moving speed of the device according to the degree of contaminant adhesion on the photovoltaic panel surface. For areas with more severe contaminant adhesion, the moving speed can be slowed down to increase the action time of the brush plate 4 and the spray, thereby improving the cleaning effect. For areas with lighter contaminant adhesion, the moving speed can be increased to improve the cleaning efficiency. According to the actual cleaning needs, the spray angle of the adjustable universal nozzle 10 can be adjusted to change the spray direction of the water flow, so that the water flow can act more accurately on the area with contaminant adhesion, thereby further enhancing the cleaning effect.

The contents not described in detail in this specification are existing technologies known to those skilled in the art.
