Technical Field

[0001] The present invention relates to the technical field of photovoltaic power generation systems, and in particular to an elevation angle adjustment device for distributed photovoltaic panels on roofs. Background Art

[0002] Distributed photovoltaic power generation specifically refers to a distributed power generation system that uses photovoltaic modules to directly convert solar energy into electrical energy. It is a photovoltaic power generation facility built near the user's site, with the operation mode of self-generation and self-use on the user side, surplus electricity being connected to the grid, and balanced regulation in the distribution system. Distributed photovoltaic power generation follows the principles of adapting to local conditions, clean and efficient, decentralized layout, and nearby utilization, making full use of local solar energy resources to replace and reduce fossil energy consumption.

[0003] At present, distributed photovoltaic power generation is widely used. Installing it on the roof can better utilize the vacant area on the roof. However, the distributed photovoltaic panels currently installed on the roof are all fixed angles, and the elevation angle of the photovoltaic panels cannot be adjusted. They cannot adapt to the light direction in different seasons, and the sunlight exposure time and area are not sufficient. Therefore, an elevation angle adjustment device for distributed photovoltaic panels on the roof is proposed. Summary of the invention

When the rack 24 moves left and right, the annular rack 15 rotates clockwise or counterclockwise with the core axis of the horizontal axis 13 as the center, and the support plate 18 can be rotated within a certain angle to enable the photovoltaic panel 4 to adapt to the light angles in different regions and seasons.

[0029] The toggle mechanism 2 comprises: four bearing seats 21 arranged in a rectangular shape and fixed on the top of the base plate 11, wherein rolling bearings are installed in the bearing seats 21; a screw rod 22 is connected between two bearings in each row, and the thread directions of the two screw rods 22 are opposite; a moving plate 23 is threadedly installed in the two screw rods 22, and a rack 24 meshing with the annular rack 15 is fixed on the top of the moving plate 23; a gear 32 is fixedly sleeved on the rod body of each screw rod 22 located outside the right end bearing seat 21, and the two gears 32 are meshingly connected. By using the mutually meshing gears 32, the two screw rods 22 can realize synchronous rotation, and a turning handle 26 is fixedly installed on the end of one of the screw rods 22. By turning the turning handle 26, the two screw rods 22 can rotate towards each other in the bearing at the same time, thereby pushing the moving plate and the rack 24 to move left and right in the screw rod 22.

[0030] As a preferred embodiment, a locking mechanism 3 is connected in the middle of the toggle mechanism 2 to enable it to achieve self-locking.

[0031] like Figure 3As shown, the locking mechanism 3 includes: two baffles 31 fixed to the top of the bottom plate 11 and located on the right side of the bearing seat 21, the two baffles 31 are respectively penetrated by the rods extending to the right of the two screws 22, and the gear 32 is arranged between the two baffles 31, and the baffle 31 plays a role in protecting the gear 32; a cylindrical box body 33 is fixed on the top of the baffle 31, and the side wall of the open end of the box body 33 is fixed together with the baffle 31, and a through hole is provided on the top wall of the box body 33, and a through hole is provided in the inner cavity of the box body 33. A locking rod 36 is installed in the middle, and a clamping column 35 is provided at the lower end of the locking rod 36. After the upper end of the locking rod 36 passes through the through hole on the top wall of the box body 33, a pull ring 37 is installed at its end. A compression spring 34 is sleeved on the rod body of the locking rod 36 between the clamping column 35 and the top wall of the box body 33. Under the tension of the compression spring 34, the lower end of the clamping column 35 is always close to the gear 32, so that the clamping column 35 can limit the rotation of the gear 32.

[0033] As a preferred embodiment, openings 19 with a width matching that of the two screw rods 22 are provided in the center of the left and right sides of the support plate 18. The openings 19 can ensure that the support plate 18 will not interfere with the screw rods 22 when the angle is changed.

[0034] The working principle of the present invention is as follows:

[0035] The base plate 11 is fixed on the roof, and the photovoltaic panel 4 is embedded in the support plate 18. When the angle of the support plate 18 needs to be adjusted, the locking rod 36 is used to pull up the clamping column 35, and the handle 26 is used to rotate the gear 32.

The support frame 17 and the support plate 18 rotate with the rotation of the sleeve 14, so as to adjust the elevation angle of the photovoltaic panel 4, release the locking rod 36, and compress the spring 34 to press the clamping column 35 back to close to the gear 32, limit the rotation of the gear 32, and fix the angle of the photovoltaic panel 4 to adapt to the light direction in different regions and seasons.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
