[0002] As an important part of renewable energy, the photovoltaic field has developed rapidly in recent years. Due to the clean and environmental protection characteristics of solar photovoltaic power generation systems, they are widely used in various scenarios, providing important support for the global energy structure transformation. In the installation and application of photovoltaic systems, photovoltaic panels, as the core components, their performance and lifespan directly affect the efficiency and economy of the entire system. In order to improve the utilization rate of photovoltaic panels, researchers have continuously explored and optimized their installation methods and protection means to meet the usage requirements under different environmental conditions.

[0003] Under the related technology, currently, the installation of photovoltaic panels mainly relies on fixed bracket structures, and the photovoltaic panels are firmly installed on the brackets by means such as bolts. Since the photovoltaic panels are exposed to the air for a long time, rain and snow weather may cause ice or water accumulation on the surface of the photovoltaic panels. In order to protect the photovoltaic panels, in the existing technology, common protection measures for photovoltaic panels include using sunshades or dust-proof nets. Although these methods can reduce the impact of the external environment on the photovoltaic panels to a certain extent, most of them require manual protection; in addition, there are also some solutions that protect the photovoltaic panels by adding physical barriers, such as using fixed enclosures or covers, but these methods often lack flexibility and are difficult to cope with dynamically changing weather conditions.

[0004] In view of the above related technology, the above conventional means still have obvious deficiencies when facing bad weather such as rain and snow. Since the photovoltaic panels are exposed to the air for a long time, rain and snow weather may cause ice or water accumulation on the surface of the photovoltaic panels, which may further lead to problems such as corrosion and short circuit, seriously affecting their service life and power generation efficiency. Therefore, how to effectively protect the photovoltaic panels from the damage of rain and snow weather has become an urgent technical problem to be solved. Summary of the Invention

[0028] The following will further describe this application in detail Figure 1-8 with reference to the accompanying drawings.

[0029] An embodiment of this application discloses a solar photovoltaic fixed support and an installation method. For the convenience of description, this application introduces azimuth terms such as the first direction, the second direction, and the third direction to form a three-dimensional reference direction. The azimuth terms such as "the first direction, the second direction, and the third direction" can specifically refer to the figure shown, where X represents the first direction X, Y represents the second direction Y, Z represents the third direction Z, and the first direction X, the second direction Y, and the third direction Z are perpendicular to each other in pairs.

[0030] Referring to Figure 1 , a solar photovoltaic fixed support includes a support assembly 1. The support assembly 1 includes a support plate 11 and a support frame 12. The support plate 11 is rotatably connected to the support frame 12. An accommodating groove 111 for accommodating a solar photovoltaic panel is provided on the support plate 11, so that the support frame 12 supports the support plate 11, and the accommodating groove 111 accommodates and supports the solar photovoltaic panel.

[0031] Referring to Figure 1, since the photovoltaic panels are exposed to the air for a long time, rain and snow weather may cause ice or water accumulation on the surface of the photovoltaic panels, which may further lead to problems such as corrosion and short - circuit. Therefore, the solar photovoltaic fixed bracket further includes a protection component 2 and a first driving component 3. The first driving component 3 includes a winding shaft 31, the winding shaft 31 is parallel to the first direction, the winding shaft 31 is rotatably connected to the support plate 11 through a first fixed seat 32, and the rotation axis 71 of the winding shaft 31 rotatably connected to the support plate 11 is parallel to the first direction. Specifically, the first fixed seat 32 is fixedly connected to the support plate 11, and the winding shaft 31 is rotatably connected to the first fixed seat 32; the protection component 2 includes a protection film cloth 21, the protection film cloth 21 is located on the support plate 11, the protection film cloth 21 includes a fixed end 211 and a free end 212, the fixed end 211 and the free end 212 are distributed in sequence in the second direction, the second direction is perpendicular to the first direction, the fixed end 211 is fixedly connected to the winding shaft 31, and the free end 212 slides along the second direction to adjust the protection film cloth 21 between the winding posture and the unfolded posture. The rotation of the winding shaft 31 drives the protection film cloth 21 to slide along the second direction to realize the adjustment of the protection effect on the solar photovoltaic panel.

[0032] Refer to Figure 1 , in rainy and snowy weather, the winding shaft 31 rotates forward to drive the protection film cloth 21 to slide along the second direction, so that the free end 212 and the fixed section of the protection film cloth 21 are distributed on both sides of the support plate 11, that is, the protection film cloth 21 is in the unfolded posture, and the protection film cloth 21 covers and protects the solar photovoltaic panel in the receiving groove; in non - rainy and snowy weather, the winding shaft 31 rotates reversely to drive the protection film cloth 21 to slide along the second direction, so that the free end 212 and the fixed section are located on one side of the support plate 11, so that the solar photovoltaic panel can normally absorb solar energy, that is, the protection film cloth 21 is in the winding posture.

[0033] In some embodiments, the protection film cloth 21 is made of a flexible material, which can be a transparent plastic material, a semi - transparent plastic material, or an opaque plastic material. In order to further improve the light absorption efficiency of the solar photovoltaic panel, in this embodiment, the material of the protection film cloth 21 is a transparent plastic flexible material. The transparent plastic has a relatively high light transmittance, and light can penetrate the protection film cloth 21 and directly irradiate on the solar photovoltaic panel. Thus, while the protection film cloth 21 provides protection, it does not affect the solar photovoltaic panel's absorption of light.

The first cleaning member 41 slides on the support plate 11 along the second direction, driving the first cleaning brush 412 to clean the dust or snow on the support plate 11 and the solar photovoltaic panel. At the same time, when the first mounting base 411 slides along the second direction, it also drives the protective film 21 to slide along the second direction, so as to protect the solar photovoltaic panel with the protective film 21.

[0035] Referring to Figure 2 and Figure 3 , in order to further clean the dust on the support plate 11, the cleaning assembly 4 further includes a water pipe 42.

The water in the first mounting base 411 further wets the first cleaning brush 412, and the first cleaning brush 412 cleans the dust on the support plate 11.

[0036] Referring to Figure 3 and Figure 4 , in order to provide a water source for the water pipe 42, the cleaning assembly 4 further includes a water collection tank 43. One end of the water pipe 42 far from the first mounting base 411 is communicated with the water collection tank 43.

When it rains, the rainwater will enter the water collection tank 43, and after further passing through the filter holes 441 of the filter plate 44, it will gather at the bottom wall of the water collection tank 43. The one-way valve 421 is started, and the water in the water collection tank 43 is pumped into the first mounting base 411 through the water pipe 42, and further the first cleaning brush 412 cleans the support plate 11 and the photovoltaic panel.

[0037] It should be noted that the water collection tank 43 can also be filled with water manually or hold rainwater to provide a water source for the first mounting base 411.
