[0002] After the 1970s, with the development of modern industry, the global energy crisis and air pollution problems have become increasingly prominent, and traditional fuel energy is decreasing day by day. At this time, solar energy has become the focus of people's attention due to its unique advantages. After the 1990s, photovoltaic power generation has developed rapidly, and photovoltaic panels will face severe weather erosion after installation, which seriously affects the service life of photovoltaic panels.

[0003] Based on the above, the inventors have discovered the following problems: after the photovoltaic panels are installed, there are no supporting protective facilities. When encountering severe weather conditions, such as heavy snow and strong winds, snow is easily accumulated on the surface of the photovoltaic panels or they are hit by foreign objects blown up by the strong wind, which will affect the normal operation and service life of the photovoltaic panels.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a photovoltaic bracket for a photovoltaic power generation substation is provided, in order to achieve a purpose with greater practical value. Utility Model Content

[0024] Example:

[0025] As attached Figure 1 To Attachment Figure 4 As shown:

[0026] The utility model provides a photovoltaic support for a photovoltaic power generation substation, including a plurality of mounting frames 1, wherein the plurality of mounting frames 1 are symmetrically installed on the ground in two groups at equal distances, and the two groups of mounting frames 1 are symmetrically installed with brackets 2 on opposite sides, and the brackets 2 are symmetrically provided with annular guide rails 3 on opposite sides, and two groups of protective components are further provided between a pair of the brackets 2, and the protective components include a plurality of baffles 4 installed between the two brackets 2, and the baffles 4 are symmetrically provided with a pair of rotating shafts 5 at the ends of one side of the brackets 2, and a pair of circular sliders 6 are rotatably connected to the surfaces of the rotating shafts 5, and the circular sliders 6 are slidably connected to the annular guide rails 3. Through the coordinated use of the brackets 2, the annular guide rails 3, the baffles 4, the rotating shafts 5 and the circular sliders 6, it is achieved that the baffles 4 can slide in the annular guide rails 3 through the circular sliders 6, so that the baffles 4 can be moved to different positions according to different needs, and a single The rotating shaft 5 is located between the circular slider 6 and the baffle 4 and is rotatably connected to a connecting plate 7. The other end of the connecting plate 7 is rotatably connected to the rotating shaft 5 on one side of the adjacent baffle 4. Through the coordinated use of the connecting plate 7 and the baffle 4, it is possible to connect multiple baffles 4 in the two groups of protection components in series, thereby connecting the baffles 4 in series into a whole, thereby achieving a protective effect on the photovoltaic panel 9, and through the connecting plate 7, it is also possible to push one baffle 4 to make the other baffles 4 connected in series with it move synchronously. Three connecting rods 8 are equidistantly installed in an array on the opposite side of the bracket 2. The three connecting rods 8 are all located on the inner side of the guide rail of the annular guide rail 3. Photovoltaic panels 9 are fixedly installed on the top of the three connecting rods 8. By arranging a connecting rod 8 at the bottom of the opposite side of the bracket 2, the photovoltaic panel 9 can be firmly installed in the device, and a driving component is also installed at the bottom of the middle connecting rod 8.

[0027] Among them, the driving component includes a dual-axis motor 10 installed at the bottom center position of the second connecting rod 8, and threaded rods 11 are installed on the output ends of both sides of the dual-axis motor 10. A pair of the threaded rods 11 are threadedly connected with connecting blocks 12, and the connecting blocks 12 are respectively fixedly connected to the side baffles 4 close to the dual-axis motor 10 in the two groups of protective components. Through the coordinated use of the dual-axis motor 10, the threaded rods 11 and the connecting blocks 12, the threaded rods 11 are synchronously rotated when the dual-axis motor 10 is driven to rotate, and the connecting blocks 12 threadedly connected on the surface thereof are driven to move, and the connecting blocks 12 are fixedly connected to the baffles 4, so they will drive the baffles 4 to move, thereby driving the entire protective component to move, thereby realizing the control of the position of the protective component, so that the protective component can be retracted to the back of the photovoltaic panel 9 in normal weather to ensure the normal operation of the photovoltaic panel 9, and the dual-axis motor 10 is driven in bad weather to make the protective component extend to protect the photovoltaic panel 9.

[0028] Among them, the thread directions of a pair of threaded rods 11 are opposite. Since the threads of the two threaded rods 11 are in opposite directions, when the dual-axis motor 10 is driven to rotate, the connecting blocks 12 on the threaded rods 11 on both sides move in opposite directions, so that the two groups of protection components can be retracted and extended at the same time, and then the two groups of protection components can be gradually moved from both sides to the middle of the annular guide rail 3, and the two groups of protection components are connected, so as to form a protection layer covering the entire surface of the photovoltaic panel 9, thereby protecting the photovoltaic panel 9.

[0029] Among them, a reinforcing rib 13 is also installed on one side of the dual-axis motor 10, and the reinforcing rib 13 is fixedly connected to the middle connecting rod 8. The two sides of the reinforcing rib 13 are rotatably connected to the ends of the threaded rod 11. Through the coordinated use of the reinforcing rib 13 and the threaded rod 11, the rigidity of the threaded rod 11 can be increased, and the threaded rod 11 can always rotate around the center of the circle, so that the threaded rod 11 can normally drive the connecting block 12 threadedly connected to it.

[0030] The surface between the two adjacent baffles 4 is installed with Oxford cloth 14. By installing Oxford cloth 14 between the two adjacent baffles 4, the gap between the two baffles 4 can be filled, thereby blocking some fine impurities.

[0031] Among them, the length of the photovoltaic panel 9 is smaller than the length of the inner guide rail of the annular guide rail 3. By limiting the size of the photovoltaic panel 9, it can be ensured that the protective components outside the photovoltaic panel 9 will not collide with the photovoltaic panel 9 when retracted and extended, causing damage to the photovoltaic panel 9, thereby avoiding the losses caused thereby.

[0032] Among them, sealing strips 15 are installed on opposite sides of the two baffles 4 away from the dual-axis motor 10 in the two groups of protective components, and the length of the sealing strip 15 is greater than the radius length of the circular slider 6. By installing the sealing strips 15 on opposite sides of two adjacent baffles 4 in the two groups of protective components, it can be achieved that when the two groups of protective components are extended and closed in the middle, the contact surfaces of the two adjacent baffles 4 of the two groups of protective components remain tight, thereby preventing debris from invading from the joints of the two groups of protective components and affecting the protective effect of the device.

[0033] The specific usage and function of this embodiment are as follows:

[0034] Before the installation and use of the utility model, the staff needs to check the internal components or structures of the device. After the inspection is correct, it can be used normally. First, three connecting rods 8 are installed in an equidistant array at the bottom of the opposite side of a pair of brackets 2, and then the protective assembly is installed in the annular guide rail 3 in the pair of brackets 2, and then the combination of the bracket 2 and the protective assembly is installed on the mounting frame 1, and then the photovoltaic panel 9 is fixed on the top of the three connecting rods 8, and then the driving assembly is installed at the bottom center of the middle bracket 2, and then the reinforcing rib 13 is fixed on one side of the dual-axis motor 10, so that the ends of the threaded rods 11 on both sides of the driving assembly are rotatably connected with the two ends of the reinforcing rib 13, and finally the connecting blocks 12 on the threaded rods 11 on both sides are connected to the baffle 4 close to the side of the dual-axis motor 10, and then the dual-axis motor 10 drives the protective assembly to check the operation. The installation of the device is completed when the operation is normal. Through the above steps, the protective assembly can be extended from the back of the photovoltaic panel 9 under severe weather conditions, thereby protecting the photovoltaic panel 9, extending the service life of the photovoltaic panel 9, and reducing the maintenance and cleaning time of the photovoltaic panel 9, thereby reducing the maintenance cost and extending the normal working time of the photovoltaic panel.
