Description

Technical Field

[0001] This invention relates to the field of solar photovoltaic support technology, specifically to a wind-resistant inclined beam rotating hinge point fully self-locking rotary support drive flat single-axis tracking bracket. Background Technology

[0002] Currently, almost all single-axis solar photovoltaic tracking supports consist of a square, round, hexagonal, or octagonal tube with small purlins supporting the solar panels. The axis of the tube serves as the center of rotation, resulting in a very large eccentric moment. Furthermore, to save costs and reduce expenses, manufacturers minimize the number of self-locking hinge points, leaving most hinge points in a free-rotating state. Therefore, severe swaying and resonance are highly likely to occur in high winds, causing many users to be overwhelmed with maintenance and repairs. Additionally, some manufacturers, in an attempt to address this eccentricity in existing power stations, have added a large-arm concrete counterweight to the existing support structure. However, due to the long arm and concentrated eccentricity, this concrete counterweight has not improved the vibration and resonance of the support structure in high winds; instead, the elasticity of the counterweight exacerbates the regional resonance.

[0003] For example, Chinese Patent Publication No. CN108282137B discloses a solar photovoltaic panel support device, including a bracket. The bracket includes a short side, a long side, and a horizontal side. The short side is opposite to the long side and connected by the horizontal side. Both the long side and the short side are perpendicular to the horizontal side. A bevel is provided at the junction of the short side and the horizontal side, forming an obtuse angle with the horizontal side for connecting the solar photovoltaic panel. Vertically arranged support ribs are provided on the horizontal side, with the top of the support ribs abutting against the solar photovoltaic panel. This invention has a reasonable structure and is easy to use. The integrated structure facilitates transportation and installation, and the reasonable structural design facilitates the installation of solar photovoltaic panels. Since solar photovoltaic panels are used outdoors, they need to be effectively protected against moisture during periods of heavy rain to prevent damage to components. However, the solar photovoltaic panels are not easy to adjust in terms of tilt angle during installation and are prone to severe swaying and resonance in windy environments. Furthermore, it cannot be adjusted for installation of solar photovoltaic panels of different lengths and widths. Summary of the Invention

[0004] The purpose of this invention is to provide a wind-resistant inclined beam rotation hinge point fully self-locking rotary support drive flat single-axis tracking bracket to solve the problems that solar photovoltaic panels are inconvenient to adjust the tilt angle during installation and are prone to severe swaying and resonance in windy environments, and cannot be adjusted according to the installation of solar photovoltaic panels of different lengths and widths.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Example 1

[0038] Please see Figures 1-10 As shown, this invention is a wind-resistant inclined beam rotation hinge point fully self-locking rotary support drive flat single-axis tracking bracket, including a main support assembly 2. The main support assembly 2 is used to support bracket 1 and bracket 4 and adjust their tilt angle. The main support assembly 2 includes...

[0039] A purlin 204 has a linkage hinge rod 1 205 hinged at one end and a linkage hinge rod 206 hinged at the other end. A mounting plate 203 is fixedly connected to the inner side of the purlin 204.

[0040] Rotating beam 207, one side of rotating beam 207 is mounted on bracket 1, and the other side of rotating beam 207 is mounted on bracket 24.

[0041] It should be noted that the rotating beam 207 is triangular in shape, which improves its support and stability. The rotating beam 207, purlin 204, linkage hinge rod 205, and linkage hinge rod 206 form a four-bar quadrilateral arrangement. The four-bar arrangement is symmetrical and is a common mechanical transmission form.

[0042] In this invention, preferably, the main support assembly 2 further includes a main connecting plate 200. Both sides of one end of the main connecting plate 200 are fixedly connected to a main fixing frame 209. The side of the main fixing frame 209 away from the main connecting plate 200 is threadedly connected to a locking bolt 210. The inner side of the main fixing frame 209 is hinged to the rotating beam 207 and the side of the linkage hinge rod 206 away from the purlin 204.

[0043] It should be noted that the locking bolt 210 can rotate to lock and stabilize the hinge between the main fixing frame 209 and the rotating beam 207. The main connecting plate 200 is provided with a connecting hole to facilitate the connection and fixation of the main connecting plate 200.

[0044] In this invention, preferably, a drive device 202 is fixedly installed on the mounting plate 203, and the drive device 202 is a worm gear reducer.

[0045] In this invention, preferably, a secondary support component 3 is also included, which is used to provide auxiliary support and angle adjustment for the first bracket 1 and the second bracket 4.

[0046] It should be noted that the number of secondary support components 3 can be increased accordingly based on the number of solar panels (two sets are set in this article).

[0047] In this invention, preferably, the secondary support assembly 3 includes a second rotating beam 307, one side of which is mounted on a first bracket 1, and the other side of which is mounted on a second bracket 4.

[0048] A secondary connecting plate 300 has secondary fixing brackets 301 fixedly connected to both sides of one end of the secondary connecting plate 300. The middle part of the secondary fixing bracket 301 is threaded with a second locking bolt 302, and the side of the secondary fixing bracket 301 away from the secondary connecting plate 300 is threaded with a third locking bolt 309.

[0049] A crossbeam 303 has a linkage hinge rod 305 hinged on one side and a linkage hinge rod 406 hinged on the other side.

[0050] It should be noted that the rotating beam 307 is triangular in shape, which improves its support and stability. The rotating beam 307, the crossbeam 303, the linkage hinge rod 305, and the linkage hinge rod 406 form a four-bar quadrilateral arrangement. The four-bar arrangement is symmetrical. The auxiliary connecting plate 300 is provided with connecting holes for easy connection and fixation. The four-bar arrangement is a common mechanical transmission form.

[0051] In this invention, preferably, the third linkage rod 305 and the fourth linkage rod 306 are hinged to the rotating beam 307 on the side away from the crossbeam 303. The crossbeam 303 is hinged to the inner side of the threaded locking bolt 302 of the auxiliary fixing frame 301, and the rotating beam 307 is hinged to the inner side of the threaded locking bolt 309 of the auxiliary fixing frame 301.

[0052] It should be noted that the locking bolt 302 can lock the hinge between the secondary fixed frame 301 and the crossbeam 303, and the locking bolt 309 can lock the hinge between the secondary fixed frame 301 and the rotating beam 307.

[0053] In this invention, preferably, a drive shaft 6 is fixedly connected to the middle of the crossbeam 303, and the drive shaft 6 is driven by the drive device 202. The drive shaft 6 passes through and is rotatably connected to the main fixed frame 209 and the auxiliary fixed frame 301.

[0054] It should be noted that a triangular connecting bracket is fixedly installed on the inner side of its crossbeam 303, and the drive shaft 6 is fixed in the middle of the triangular connecting bracket.

[0055] During implementation, when it is necessary to adjust the angle of bracket 1 and bracket 2 4, a drive device 202 is set up. The drive device 202 drives the transmission shaft 6 to rotate slightly along the main fixed frame 209 and the auxiliary fixed frame 301. The rotation of the transmission shaft 6 in turn rotates the crossbeam 303, changing its angle. This causes the crossbeam 303, the linkage hinge rod 305, the linkage hinge rod 4 306, and the rotating beam 2 307 to fold along the auxiliary fixed frame 301, thereby adjusting the angle and achieving the four-bar linkage movement. This causes the rotating beam 2 307 to tilt, and the two sides of the rotating beam 2 307... The side supports 1 and 4 are adjusted to adjust the angle of the solar panel. When the supports 1 and 4 are adjusted, the rotating beam 207, the linkage hinge rod 206, the linkage hinge rod 205, and the purlin 204 are folded and deformed along the main fixed frame 209, thus performing a four-bar linkage movement. By tightening the locking bolts 309, 302, and 210, the hinge is locked, thereby achieving the purpose of auxiliary self-locking. The drive device 202 stops driving, thus achieving the purpose of active self-locking.

[0056] It should be noted that the self-locking characteristic of the worm gear is mainly based on the friction between the worm and the worm wheel. When the lead angle of the worm is less than the equivalent friction angle between the meshing teeth, the mechanism has self-locking properties. This self-locking characteristic can prevent the worm wheel from reversing, thereby restricting the movement of the four-link. The rotating beam 207, the linkage hinge rod 206, the linkage hinge rod 205, and the purlin 204 achieve self-locking at all hinge points by stopping the meshing of the worm gear. Furthermore, limit locking components are provided at the hinge points of the four-link, so that when the four-link moves to a designated position, the self-locking at all hinge points can be achieved through the cooperation between the locking components and the worm gear.

[0057] Example 2

[0058] In this invention, preferably, connecting components 5 are installed at symmetrical positions on both bracket 1 and bracket 4. The connecting components 5 are used to install the photovoltaic panels and adjust the distance between them.

[0059] It should be noted that the number of its connecting components 5 can be increased according to the number of solar panels.

[0060] In this invention, preferably, the connecting component 5 includes a sliding block 501, which is slidably connected to the first bracket 1 and the second bracket 4. A movable plate 500 is fixedly connected to one side of the sliding block 501, and a limit post 502 is fixedly installed inside the movable plate 500.

[0061] The movable block 503 is slidably connected to the limiting post 502. The limiting block 504 is fixedly connected to the movable block 503, and the inner side of the limiting block 504 is hinged to the support block 505. At the same time, the mounting plate 506 is fixedly connected to one side of the support block 505.

[0062] It should be noted that the mounting plate 506 has connection holes around its perimeter for easy connection to the solar panel.

[0063] In this invention, preferably, the sliding block 501 slides through the sliding grooves opened on the bracket 1 and the bracket 2 4, the moving block 503 slides through the moving groove opened on the moving plate 500, and the limiting post 502 is fixedly installed in the moving groove opened on the inner side of the moving plate 500.

[0064] During implementation, two sets of mounting plates 506 are pulled. The mounting plates 506, along with the support blocks 505, limit blocks 504, moving blocks 503, limit posts 502, moving plates 500, and sliding blocks 501, move along the sliding grooves opened on bracket 1 and bracket 2 to adjust the relative positions between them laterally. The moving blocks 503 are pushed or pulled. The moving blocks 503, along with the limit blocks 504, support blocks 505, and mounting plates 506, move along the limit posts 502 and the moving grooves to adjust the relative positions between them longitudinally. The solar panels are fixedly connected to the mounting plates 506 through the connecting holes opened on the mounting plates 506 with bolts, so that the solar panels can be adjusted laterally and longitudinally according to their length and width during fixed installation.

All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
