Description

Technical Field

[0001] This utility model relates to the field of photovoltaic grid panels, specifically to a self-cleaning photovoltaic grid panel. Background Technology

[0002] Photovoltaic grid panels, also known as photovoltaic cell grid panels, are key components that separate the electrodes of photovoltaic cells from the electrolyte and provide electron transport. In photovoltaic cells, light passes through the grid panel into the semiconductor inside the cell, where energy exchange occurs and electrons are transferred to the electrodes. Photovoltaic grid panels are widely used in photovoltaic power generation and solar power generation. With the increasing global demand for renewable energy, the photovoltaic industry has developed rapidly. As a key component in photovoltaic cell systems, the quality and design of photovoltaic grid panels have a significant impact on the overall performance of photovoltaic panels.

[0003] A search revealed a solar photovoltaic grid panel with announcement number CN217824859U. This invention discloses a solar photovoltaic grid panel that is not easily adjustable after installation, significantly reducing its efficiency and failing to meet user needs. The proposed solution includes an installation frame containing the grid panel body. A base plate is located on the lower side of the frame, and an adjustment mechanism is mounted on the upper surface of the base plate. In this invention, a motor drives a moving block on a screw via a rotating shaft to move within a second sliding groove. Fixed blocks on both sides of the installation frame are hinged to a first hinge block. A swing rod is hinged at one end to the installation frame and at the other end to a second hinge block on the upper surface of the base plate. When the moving block moves towards the swing rod, both ends of the swing rod rotate at the hinge point, causing the end of the installation frame near the swing rod to swing, thereby changing the angle of the grid panel body and effectively meeting user needs.

[0004] During use, existing photovoltaic (PV) grid panels, if left uncleaned for extended periods, can develop chemical substances in the dirt and dust on their surface that corrode the PV materials, accelerating the aging process and shortening their lifespan. Furthermore, the lack of self-cleaning capabilities necessitates manual cleaning, which is not only time-consuming and labor-intensive but also increases labor costs. The PV grid panels in the aforementioned comparative case also lack self-cleaning capabilities. Such long-term use will negatively impact the performance, maintenance costs, and environmental impact of the PV grid panels.

[0005] Therefore, it is necessary to invent a self-cleaning photovoltaic grid to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a self-cleaning photovoltaic (PV) grid panel. This panel achieves self-cleaning through a self-cleaning brush, water collection box, filter screen, water storage box, first pressurized water pump, circulation pipe, second pressurized water pump, and self-cleaning chamber. Simultaneously, the cleaned dirt and water flow into the water collection box, are filtered by the filter screen, and then re-enter the water storage box. This further saves water resources during self-cleaning, avoiding the waste of water resources in traditional cleaning methods, reducing cleaning costs, and achieving deep cleaning of the PV grid panel surface, thus improving cleaning effectiveness. This addresses the problem in existing PV grid panels where, due to prolonged lack of cleaning, the chemicals in the dirt and dust on the surface can corrode the photovoltaic materials, accelerating the aging process and shortening the service life. Furthermore, the lack of self-cleaning capability requires manual cleaning, which is time-consuming, labor-intensive, and increases labor costs. The PV grid panels in the aforementioned comparative case also lack self-cleaning capability, which, with long-term use, can adversely affect the performance, maintenance costs, and environmental impact of the PV grid panel.

[0008] A self-cleaning frame is installed on the outside of the photovoltaic grid panel body for self-cleaning. A servo motor is fixedly installed on the top of the self-cleaning frame. A threaded screw is fixedly connected to the output end of the servo motor. A threaded sleeve is threadedly connected to the outside of the threaded screw. A self-cleaning brush is fixedly installed on the outside of the threaded sleeve.

[0009] The bottom bracket is set at the bottom of the photovoltaic grid panel body and is used to connect and install the water collection box. The water collection box has a fixing bolt through it, and the front end thread of the fixing bolt has a filter screen through it.

[0010] The top plate, located above the main body of the photovoltaic grid panel, is used to connect and install a water storage box.

[0015] Preferably, the number of pressurized nozzles is set to multiple, and the multiple pressurized nozzles are distributed at equal intervals on the self-cleaning cavity.

[0016] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0017] 1. This utility model includes a self-cleaning brush, a water collection box, a filter screen, a water storage box, a first pressurized water pump, a circulation pipe, a second pressurized water pump, and a self-cleaning chamber. When using the photovoltaic grid panel, the second pressurized water pump draws water from the water storage box and delivers it to the self-cleaning chamber, allowing multiple pressurized nozzles to spray water onto the photovoltaic grid panel. This ensures a thorough cleaning by the self-cleaning brush from top to bottom, thus enabling the photovoltaic grid panel to self-clean. Simultaneously, the cleaned dirt and water flow into the water collection box, are filtered by the filter screen, and then returned to the water storage box, further saving water. This design eliminates water consumption during the self-cleaning of photovoltaic (PV) grid panels, thus avoiding the waste of water resources in traditional cleaning methods, reducing cleaning costs, and enabling deep cleaning of the PV grid panel surface, improving cleaning effectiveness. Furthermore, through the coordinated operation of components such as the first pressurized water pump, the second pressurized water pump, the self-cleaning chamber, the pressurized nozzle, and the self-cleaning brush, the design achieves automated cleaning of PV grid panels, reducing the labor intensity of manual cleaning and improving cleaning efficiency. Compared to traditional manual cleaning methods, this design is more environmentally friendly and energy-saving, reducing environmental pollution and the frequency and cost of manual cleaning.

[0018] 2. This utility model includes a photovoltaic grid panel body, a self-cleaning frame, a servo motor, a threaded screw, a threaded sleeve, a self-cleaning brush, a water collection box, fixing bolts, and a filter screen. When using the photovoltaic grid panel, the servo motor drives the threaded screw to rotate, allowing the threaded sleeve to drive the self-cleaning brush to clean the outer surface of the photovoltaic grid panel body from top to bottom. This cleaning power is sufficient to remove dirt and dust from the surface of the photovoltaic grid panel. Moreover, after long-term use, only cleaning or replacing the self-cleaning brush and the filter screen in the water collection box is needed to ensure the cleanliness of the photovoltaic grid panel during cleaning. This design makes the maintenance process relatively simple, requiring only periodic cleaning or replacement of the self-cleaning brush and the filter screen, reducing maintenance costs and time costs, while also improving the reliability and stability of the equipment.

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] This utility model provides, for example Figure 1-5 The self-cleaning photovoltaic grid shown includes a photovoltaic grid body 1 and a main body for electron transmission;

[0029] The self-cleaning frame 2 is set outside the photovoltaic grid panel body 1 for self-cleaning. A servo motor 3 is fixedly installed above the self-cleaning frame 2. A threaded screw 4 is fixedly connected to the output end of the servo motor 3. A threaded sleeve 5 is threadedly connected to the outside of the threaded screw 4. A self-cleaning brush 6 is fixedly installed outside the threaded sleeve 5.

[0030] The bottom bracket 7 is set at the bottom of the photovoltaic grid panel body 1 and is used to connect and install the water collection box 8. The water collection box 8 is connected to the outside of the fixing bolt 9, and the front end of the fixing bolt 9 is connected to the filter screen 10.

[0031] The top plate 14 is located above the main body 1 of the photovoltaic grid panel and is used to connect and install the water storage box 15. A first pressurized water pump 16 is fixedly installed on the outside of the water storage box 15. A water inlet 18 is opened on the top of the water storage box 15. A second pressurized water pump 19 is fixedly installed on the top of the water storage box 15. A delivery pipe 20 is fixedly installed at the output end of the second pressurized water pump 19. The other end of the delivery pipe 20 is fixedly connected to a self-cleaning chamber 21. Pressurized nozzles 22 are fixedly installed at the bottom of the self-cleaning chamber 21. Water resources in the water storage box 15 can be drawn by the second pressurized water pump 19 and delivered to the self-cleaning chamber 21. Multiple pressurized nozzles 22 spray out at the main body 1 of the photovoltaic grid panel, so that the self-cleaning brush 6 can clean more thoroughly when cleaning from top to bottom. This also enables the photovoltaic grid panel to achieve the purpose of self-cleaning.

[0032] like Figure 1 , Figure 2 and Figure 3 As shown, the self-cleaning brush 6 is slidably connected to the self-cleaning frame 2. The threaded screw 4 and the threaded sleeve 5 work together. The servo motor 3 drives the threaded screw 4 to rotate, so that the threaded sleeve 5 can drive the self-cleaning brush 6 to clean the outer surface of the photovoltaic grid panel body 1 from top to bottom. The filter screen 10 is threadedly connected to the water collection box 8, and the bottom bracket 7 is fixedly connected to the water collection box 8. The dirt and water after cleaning flow into the water collection box 8 together, and after being filtered by the filter screen 10, they are reintroduced into the water storage box 15. This further saves water resources during the self-cleaning of the photovoltaic grid panel. A horizontal frame plate 11 is fixedly installed on the back of the self-cleaning frame 2. Movable frames 12 are fixedly installed on both sides of the outer side of the horizontal frame plate 11. A support rod 13 is movably connected inside the movable frame 12. The movable frame 12 and the support rod 13 are used to assist in the installation of the photovoltaic grid panel.

[0033] like Figure 1 , Figure 4 and Figure 5 As shown, a circulation pipe 17 is fixedly installed at the output end of the first pressurized water pump 16, and the other end of the circulation pipe 17 is fixedly connected to the water collection box 8. The first pressurized water pump 16 and the circulation pipe 17 are used to extract the filtered water resources at the bottom of the water collection box 8 and re-input them into the water storage box 15 for use. The number of pressurized nozzles 22 is set to multiple, and the multiple pressurized nozzles 22 are evenly distributed on the self-cleaning chamber 21. The multiple pressurized nozzles 22 are aimed at the photovoltaic grid panel body 1 and sprayed out, which will make the cleaning force sufficient and improve the self-cleaning cleaning ability of the photovoltaic grid panel.

[0034] The working principle of this utility model is as follows: First, connect the external power supply. At the location where the photovoltaic grid panel needs to be installed, unfold the support rod 13 through the horizontal frame plate 11 and the movable frame 12 to install the photovoltaic grid panel in the current position. After the photovoltaic grid panel has been used for a period of time, turn on the switch of the second pressurized water pump 19. The second pressurized water pump 19 draws water from the water storage box 15 and delivers it to the self-cleaning chamber 21, allowing multiple pressurized nozzles 22 to spray water at the photovoltaic grid panel body 1. Then, turn on the switch of the servo motor 3. The servo motor 3 drives the threaded screw 4 to rotate, causing the threaded sleeve 5 to drive the self-cleaning brush 6 to clean the outer surface of the photovoltaic grid panel body 1 from top to bottom. This top-to-bottom cleaning by the self-cleaning brush 6 can clean more thoroughly and also enables the photovoltaic grid panel to achieve self-cleaning. Subsequently, the cleaned dirt and water flow together into the water collection box 8 and pass through the filter screen 1. After filtration of 0, turn on the switch of the first pressurized water pump 16. The first pressurized water pump 16 and the circulation pipe 17 draw the filtered water from the bottom of the water collection box 8 and re-input it into the water storage box 15 for use. This further saves water resources during the self-cleaning of the photovoltaic grid panel, avoids the waste of water resources in the traditional cleaning method, reduces cleaning costs, and can also achieve deep cleaning of the surface of the photovoltaic grid panel, improving the cleaning effect. At the same time, after long-term use, only cleaning or replacing the self-cleaning brush 6 and the filter screen 10 in the water collection box 8 is needed to ensure the cleanliness of the photovoltaic grid panel during cleaning. Finally, after completing the installation and use of all photovoltaic grid panels according to the above operations, turn off the switch of the servo motor 3, and turn off the switches of the first pressurized water pump 16 and the second pressurized water pump 19. If not used for a long time, simply disconnect the external power supply. In this way, the use process of the self-cleaning photovoltaic grid panel is completed.

[0035] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
