Description

Technical Field

[0001] The utility model relates to the field of photovoltaic power generation, and in particular to a photovoltaic component lighting surface cleaning mechanism and a photovoltaic component. Background Art

[0002] Photovoltaic modules are devices that use solar energy to convert light energy into electrical energy. When in use, they generally need to be placed on rooftops or in areas with sufficient outdoor sunlight, such as deserts. After long-term use, dust will accumulate on the surface of the photovoltaic panels, blocking light transmittance and affecting the power generation efficiency of the photovoltaic modules.

[0003] The patent with application number 202122349788.5 provides a solar photovoltaic module with a wiping and dust removal function, which wipes the surface of the photovoltaic panel with a reciprocating strip brush to remove dust adhering to the surface. However, since the brush is also exposed to the outdoors, dust will accumulate on the brush. In severe cases, wiping the photovoltaic panel will cause secondary pollution. In order to ensure the cleaning effect, the brush can only be cleaned or replaced regularly, which undoubtedly increases the labor intensity of the workers.

[0004] In order to solve the above problems, people have been seeking an ideal technical solution. Summary of the invention

[0005] The purpose of the utility model is to address the deficiencies of the prior art and thus provide a photovoltaic component lighting surface cleaning mechanism and a photovoltaic component which are scientifically designed, will not cause secondary pollution when cleaning photovoltaic panels, have lower labor intensity for workers, and are highly practical.

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a photovoltaic component lighting surface cleaning mechanism, including a glass water storage tank, a spray pump, a spray transverse tube, two sliding rods, a scraping mechanism and a driving motor, the spray transverse tube is used to be installed horizontally to the top of the photovoltaic panel, the spray transverse tube is provided with a plurality of nozzles at equal intervals on the side facing the photovoltaic panel, the liquid inlet of the spray pump is connected to the liquid outlet of the glass water storage tank, and the liquid outlet of the spray pump is connected to the liquid inlet of the spray transverse tube; the two sliding rods are used to be installed in parallel to the two sides of the photovoltaic panel, the driving motor drives the scraping mechanism to slide back and forth along the sliding rod, and the scraping mechanism is used to scrape the lighting surface of the photovoltaic panel.

[0007] Based on the above, the scraping mechanism includes a base body and a rubber scraper for contacting the lighting surface of the photovoltaic panel. A clamping groove is provided on the base body, and the rubber scraper is detachably installed in the clamping groove.

[0008] Based on the above, the driving motor drives the scraping mechanism to move through a sprocket chain mechanism, and the two ends of the base are fixedly connected to the chains on both sides.

[0009] Based on the above, a liquid level sensor for monitoring the liquid level of the glass water is provided in the glass water storage tank.

[0010] The utility model also provides a photovoltaic assembly, comprising a photovoltaic panel and the photovoltaic assembly lighting surface cleaning mechanism as described above.

[0011] Based on the above, the glass water storage tank, the spray pump and the drive motor are all arranged below the photovoltaic panel.

[0012] The utility model has substantial features and progress compared with the prior art. Specifically, the utility model stores glass water in the glass water storage tank. After the spray pump is started, the spray cross pipe can spray the glass water onto the top of the photovoltaic panel. The scraping mechanism blocks the glass water, which is similar to the principle of a car wiper. After the drive motor is started, the glass water is evenly scraped as the scraping mechanism moves back and forth, thereby cleaning the lighting surface of the photovoltaic panel. A tank of glass water can be used for cleaning for a long time. The utility model has the advantages of scientific design, no secondary pollution when cleaning the photovoltaic panel, lower labor intensity for workers, and strong practicality.

[0013] Furthermore, the provision of the liquid level sensor can monitor the liquid level of the glass water in the glass water storage tank, facilitating timely replenishment. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The technical solution of the utility model is further described in detail below through specific implementation methods. Example 1

[0018] like Figure 1 and Figure 2As shown, a photovoltaic module lighting surface cleaning mechanism includes a glass water storage tank 1, a spray pump 2, a spray transverse pipe 3, two sliding rods 5, a scraping mechanism and a driving motor 6. The spray transverse pipe 3 is used to be horizontally installed on the top of the photovoltaic panel 7. The spray transverse pipe 3 is provided with a plurality of nozzles 4 at equal intervals on the side facing the photovoltaic panel 7. The liquid inlet of the spray pump 2 is connected to the liquid outlet of the glass water storage tank 1, and the liquid outlet of the spray pump 2 is connected to the liquid inlet of the spray transverse pipe 3. After the spray pump 2 is started, the glass water in the glass water storage tank 1 can be input into the spray transverse pipe 3, and then sprayed to the top of the photovoltaic panel 7 by the nozzle 4.

[0019] The two sliding rods 5 are used to be installed in parallel to the two sides of the photovoltaic panel 7. The driving motor 6 drives the scraping mechanism to slide back and forth along the sliding rods 5. The scraping mechanism specifically includes a base 8 and a rubber scraper 9 for contacting the lighting surface of the photovoltaic panel 7. A clamping groove is opened on the base 8. The rubber scraper 9 is detachably installed in the clamping groove. The glass water sprayed from the nozzle 4 will be blocked by the rubber scraper 9. As the scraping mechanism reciprocates, the scraping mechanism scrapes the glass water off the lighting surface of the photovoltaic panel 7 to complete the cleaning.

[0020] The driving motor 6 drives the scraping mechanism to move specifically through the sprocket chain mechanism 10. The two ends of the base 8 are fixedly connected to the chains on both sides. As the chain is driven, the scraping mechanism is pulled to move. This driving method does not block the lighting surface of the photovoltaic panel 7 and does not affect the power generation efficiency.

[0021] In order to facilitate the staff to know the storage amount of the glass water in time, the glass water storage tank 1 is provided with a liquid level sensor for monitoring the liquid level of the glass water, so as to facilitate timely addition.

[0022] During specific use, this patent refers to the cleaning method of automobile glass. First, the spray pump 2 is started, and the nozzle 4 on the spray transverse pipe 3 sprays the glass water. The rubber scraper 9 blocks the glass water first, and then the drive motor 6 is started. The rubber scraper 9 reciprocates along the photovoltaic panel 7 several times to scrape the glass water evenly to achieve the cleaning function. In this way, a can of glass water can be used for cleaning for a long time, thereby reducing the workload of the staff.

[0023] Taking into account the convenience of field work, a PLC can also be set to perform timed control on the drive motor 6 and the spray pump 2, for example, they can be cleaned once every morning; as for the power supply problem, part of the electricity generated by the photovoltaic panel 7 can be intercepted for power supply, or dry batteries can be used for power supply. Example 2

[0024] A photovoltaic assembly includes the photovoltaic assembly lighting surface cleaning mechanism in Example 1, wherein the glass water storage tank 1, the spray pump 2 and the drive motor 6 are all arranged below the photovoltaic panel 7 to avoid wind and rain.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the utility model, which should be included in the scope of the technical solution for protection of the utility model.
