Technical Field

[0001] The utility model relates to the technical field of new energy, in particular to a protective structure for photovoltaic power generation. Background Art

[0002] Photovoltaic power generation is a device that absorbs sunlight through solar panels and converts solar radiation energy directly or indirectly into electrical energy through photoelectric effect or photochemical effect. It has three advantages: permanence, cleanliness, and flexibility. It can convert sunlight into electrical energy alone. Compared with thermal power generation and nuclear power generation, it does not cause environmental pollution and is more environmentally friendly. The protective structure of photovoltaic power generation is used to protect the power generation device.

[0003] The existing technology has the following problems:

[0004] 1. Some existing photovoltaic power generation equipment are equipped with dust covers as anti-fouling devices. However, the dust covers can prevent dust from falling on the photovoltaic panels, but it is difficult to clean themselves. When the dust covers are full of dust, it will affect the light transmittance and the power generation efficiency of the photovoltaic power generation equipment.

[0005] 2. Existing dust covers are mostly fixed by nuts and bolts, which makes it very inconvenient to disassemble and replace.

[0006] To this end, we proposed a photovoltaic power generation protection structure to solve the above-mentioned drawbacks. Utility Model Content

When the transparent plate needs to be cleaned, the operator only needs to turn on the No. 1 motor through the controller, and the No. 1 motor drives the No. 2 gear to rotate. Since the No. 2 gear is engaged with the No. 1 gear, the rotation of the No. 2 gear will drive the No. 1 gear, and the No. 1 gear will drive the No. 1 screw to rotate. The rotation of the No. 1 screw will cause the slider connected to its surface to move back and forth. Scrapers are provided on both sides of the slider.

[0042] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0043] Example: Figure 1 As shown, a protective structure for photovoltaic power generation includes: a support column 4 is the main body of the utility model, which is used to suspend the photovoltaic power generation equipment to prevent it from being placed on the ground and being affected by pollutants or water on the ground; a photovoltaic panel 1 is the main body of the photovoltaic power generation equipment, which is used to realize the main functions of the photovoltaic power generation device; a No. 1 screw 9 is used to drive the slider 6 to move back and forth, so as to expand the cleaning range of the transparent plate 2; a scraper 5 is used to move back and forth on the transparent plate 2 driven by the slider 6 to clean the pollutants on the transparent plate 2 to prevent them from adhering to the transparent plate 2 and affecting the use efficiency of the photovoltaic panel; two fixing clips 7 are provided, which are movably arranged on the connecting block 3, and are used to fix the transparent plate 2 on the surface of the photovoltaic panel 1, so that the transparent plate 2 has a protective effect on the photovoltaic panel 1, isolates the external dust, and prevents the dust from falling on the photovoltaic panel 1 and affecting the life of the photovoltaic panel 1.

[0044] like Figure 2 As shown, it includes: a No. 1 gear 10 is arranged at one end of the No. 1 screw 9 and connected to the No. 1 screw 9. The No. 1 gear 10 is used to drive the No. 1 screw 9 to rotate under the influence of the No. 2 gear 11 to ensure that the cleaning device can move back and forth. The No. 2 gear 11 is used to be driven by the No. 1 motor 12 to rotate the No. 1 gear 10. The No. 1 motor 12 is used to rotate the No. 2 gear 11 to provide kinetic energy for the cleaning device, which can quickly clean the transparent plate to prevent dust and debris from accumulating on the transparent plate and affecting the power generation efficiency of the photovoltaic power generation equipment. The motor box 8 is arranged on the surface of the connecting block 3, and a groove is provided inside to facilitate the connection between the No. 2 gear 11 and the No. 1 gear 10. At the same time, it has a certain protective effect on the No. 1 motor 12 to prevent the No. 1 motor 12 from being eroded by the outside. The connecting block 3 is the main connecting structure used to connect the photovoltaic panel 1 and the transparent plate 2 to the support column 4. It is also used to install the cleaning device, which can make the cleaning scraper fit closely with the part to be cleaned. It has a cleaning function while realizing the connection function, enriching the functionality of the protective structure and making the protective structure more perfect.

[0045] like Figure 3 and Figure 4As shown, it includes: a controller 13 is electrically connected to the No. 1 motor 12 and the No. 2 motor 17, and is used to control the switches of the No. 1 motor 12 and the No. 2 motor 17. The controller 13 can be used for unified operation and scheduling, avoiding the complexity of individually controlling each device and improving the user's convenience. The No. 2 motor 17 is used to drive the No. 2 bevel gear 16 to rotate, providing power for the movement of the fixing clamp 7. The No. 2 bevel gear 16 is driven by the No. 2 motor 17 to rotate the No. 1 bevel gear 15. The No. 1 bevel gear 15 is engaged with the No. 2 bevel gear 16, and the power transmitted by the No. 2 bevel gear 16 is then transmitted to the No. 2 screw 14. The No. 2 screw 14 is arranged inside the fixing clamp 7, connecting the fixing clamp 7 with the connecting block 3. By being driven by the No. 1 bevel gear 15 to rotate, the fixing clamp 7 moves back and forth on the No. 2 screw 14, so as to fix the transparent plate 2, simplify the installation steps of the protective structure, and greatly improve the installation and disassembly efficiency of the protective structure.

[0046] In this embodiment: the control panel control circuit can be implemented by simple programming by those skilled in the art, which is common knowledge in the art. It is only used without modification, so the control method and circuit connection will not be described in detail.

[0047] Working principle: When the transparent plate needs to be cleaned, the operator only needs to turn on the No. 1 motor 12 through the controller 13, and the No. 1 motor 12 drives the No. 2 gear 11 to rotate. Since the No. 2 gear 11 is engaged with the No. 1 gear 10, the rotation of the No. 2 gear 11 will drive the No. 1 gear 10, and the No. 1 gear 10 will drive the No. 1 screw 9 to rotate. The rotation of the No. 1 screw 9 will cause the slider 6 connected to its surface to move back and forth. Scrapers 5 are provided on both sides of the slider 6. The scrapers 5 are in close contact with the surface of the transparent plate 2. The scrapers move back and forth on the transparent plate 2 to clean the transparent plate 2. After cleaning, The No. 1 motor 12 is turned off through the controller 13. When the transparent plate 2 is damaged and needs to be replaced, the operator only needs to turn on the No. 2 motor 17 through the controller 13. The No. 2 motor 17 drives the No. 2 bevel gear 16 to rotate. Since the No. 2 bevel gear 16 is engaged with the No. 1 bevel gear 15, the rotation of the No. 2 bevel gear 16 will drive the No. 1 bevel gear 15 to rotate, and the No. 1 bevel gear 15 will drive the No. 2 screw 14 to rotate. The rotation of the No. 2 screw 14 will move the fixing clip 7 connected to its surface. By moving the fixing clip 7, the transparent plate 2 is released and the transparent plate 2 can be easily removed.
