Technical Field

[0001] The invention belongs to the technical field of photovoltaic brackets, in particular to a desert photovoltaic bracket. Background Art

[0002] Photovoltaic power generation, as a clean energy technology, has been widely used in desert areas in recent years. Desert areas have abundant solar energy resources, but due to their special geographical and climatic conditions, especially the harsh environment such as strong winds and sandstorms, the stability and durability of photovoltaic brackets are severely challenged. At present, desert photovoltaic brackets usually adopt adjustable structures to adapt to solar radiation at different angles, thereby improving power generation efficiency. However, these adjustment structures are often exposed to the external environment and are susceptible to direct erosion by wind and sand. Long-term wind and sand invasion will cause wear, stagnation and even failure of the adjustment components, seriously affecting the normal operation and maintenance of photovoltaic brackets.

[0003] However, in the prior art, although there are some protective measures for photovoltaic brackets, such as adding windbreaks or sand-proof nets, these solutions mostly focus on overall protection and fail to effectively protect the precise adjustment structure inside the bracket. In addition, these protective measures are often complex in structure, increasing manufacturing costs and installation difficulties.

[0004] To this end, those skilled in the art have proposed a desert photovoltaic bracket to solve the problems raised by the background technology.

[0005] The above information disclosed in this background technology is only used to increase the understanding of the background technology of the present invention and therefore, it may include information that does not constitute the prior art known to ordinary technicians in this field.

When the photovoltaic component is pitched, as one end of the photovoltaic component drops and the other end rises, the protection main board on one side will press the protection sub-board, and the protection main board on the other side will separate from the protection sub-board outwardly.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. It should be pointed out that the drawings are schematic and not drawn to scale. For the sake of clarity and convenience in the figures, the relative sizes and proportions of the parts shown in the figures are exaggerated or reduced in size, and any size is only exemplary and not restrictive.

[0031] Embodiment 1:

[0032] See also Figure 1 - Figure 5 As shown, a desert photovoltaic bracket includes a base 2, a supporting assembly 3 is installed on the base 2, a photovoltaic assembly 4 is installed on the supporting assembly 3, and a protective assembly 5 is also installed on the base 2; the protective assembly 5 includes a fixed plate 51 installed on the base 2, the fixed plate 51 is movably connected with a connecting boss 53, the connecting boss 53 is connected with a connecting plate 54, the lower surface of the photovoltaic assembly 4 is connected with a protective main board 55, the connecting plate 54 is rotatably connected with a protective sub-board 56, and the protective main board 55 is movably connected with the protective sub-board 56.

[0033] Specifically, buried piles 1 are installed on the lower surface of the base 2, and two protective components 5 are symmetrically arranged about the column 31. The base 2 is used to install the entire device on the ground, and the support component 3 is used to install the photovoltaic component 4. The support component 3 also serves to adjust the tilt direction angle of the photovoltaic component 4. The protective component 5 is used to protect the support component 3 to prevent external wind and sand from blowing directly on the support component 3, thereby reducing corrosion and damage.

[0034] See also Figure 4 and Figure 5As shown, the fixing plate 51 is installed on both sides of the column 31 and is symmetrically arranged about the column 31. The buried pile 1 is used to fix the device in the desert to prevent settlement. An arc-shaped slide groove is opened on the fixing plate 51, and the curvature is adapted to the tilt curvature of the photovoltaic module 4. The connecting boss 53 is slidably connected to the slide groove and can move along the slide groove. The connecting plate 54 is fixedly connected to the connecting boss 53, and the connecting plate 54 is rotatably connected to the protective sub-plate 56, so that the photovoltaic module 4 can synchronously drive the connecting boss 53 to move along the slide groove when tilting. The connecting boss 53 drives the protective sub-plate 56 to tilt through the connecting plate 54. Since the protective main board 55 is installed on the photovoltaic module 4, the protective main board 55 and the protective The relative positions of the sub-panels 56 do not change and can follow the tilt. When the photovoltaic module 4 is pitched, as one end of the photovoltaic module 4 drops and the other end rises, the protective main board 55 on one side will press the protective sub-panel 56, and the protective main board 55 on the other side will separate from the protective sub-panel 56 outward. Since the protective sub-panel 56 is rotatably connected to the connecting plate 54 and initially has an inclination, the protective sub-panel 56 on one side is pressed inward, and the protective sub-panel 56 on the other side is expanded outward under the action of gravity. The setting direction of the protective main board 55 and the protective sub-panel 56 is set according to the local wind direction. The internal device is protected by facing the wind with the protective main board 55 and the protective sub-panel 56 to prevent wind and sand from blowing directly into the structure.

[0035] See also Figure 2 As shown, further, a plurality of additional mounting seats 57 are installed on the outer surfaces of the protective main board 55 and the protective sub-board 56, and the additional mounting seats 57 are used to install a tarpaulin. By setting the additional mounting seats 57, the positions on both sides where the protective main board 55 and the protective sub-board 56 are not set can be covered with a tarpaulin, and the tarpaulin can cover other gaps, and a margin is left when installing the tarpaulin for the movement of the photovoltaic components 4.

[0036] See also Figure 2 As shown, further, a limit member 6 is provided at the connection between the protective main plate 55 and the protective sub-plate 56. The limit member 6 includes a limit groove 61 arranged on the back side of the protective main plate 55, and a limit boss 62 is provided on the top of the protective sub-plate 56. The limit boss 62 is slidably connected with the limit groove 61. The limit groove 61 can be a groove. The limit boss 62 is a rod body arranged on the top side of the protective sub-plate 56. Both ends of the limit boss 62 are inserted into the limit groove 61, so as to prevent the protective sub-plate 56 from being separated from the protective main plate 55.

[0037] As can be seen from the above, by providing a protective component 5 on the windward side of the photovoltaic support, the support component 3 of the photovoltaic support is protected, and wind and sand will not directly blow the support component 3, thereby increasing the service life of the device.

[0040] Specifically, the other end of the pitch cylinder 34 is rotatably connected to the bottom of the column 31, and the connection between the pitch link 33 and the pitch seat 32 is close to one end of the pitch link 33. The pitch cylinder 34 is installed at the end of the pitch link 33 away from the pitch seat 32. The pitch adjustment of the pitch link 33 can be achieved by controlling the extension and retraction of the pitch cylinder 34.
