Description

Technical Field

[0001] The invention relates to the technical field of solar photovoltaic brackets, and in particular to a flat single-axis tracking bracket driven by a fully self-locking slewing support at a rotating hinge point of a wind-resistant inclined beam. Background Art

[0002] At present, almost all of the solar photovoltaic tracking flat single-axis structural brackets place small purlins on a square tube, round tube, hexagonal tube or octagonal tube to support the solar panels, and the axis of the square tube, round tube, hexagonal tube or octagonal tube is the rotation center of the rotating hinge. In this way, the rotation eccentric moment is very large. In addition, in order to save costs and reduce construction costs, manufacturers try to reduce self-locking braking hinges as much as possible, and most of the rotating hinges are in a free rotation state. Therefore, serious swings and resonances are very likely to occur in strong wind environments, so that many users of this product are tired of repairing and busy with maintenance; in addition, in order to solve the eccentric power station that has been built, some manufacturers have to add a cement counterweight with a larger crank arm to the existing power station bracket. Unexpectedly, the cement counterweight has a longer crank arm and concentrated eccentricity, and does not improve the vibration and resonance of the bracket in a strong wind environment. On the contrary, the elasticity of avoidance makes the regional resonance more serious.

[0003] For example, Chinese patent authorization announcement number CN108282137B discloses a solar photovoltaic panel support device, including a bracket, wherein the bracket includes a short side, a long side and a transverse side, the short side is opposite to the long side and connected by the transverse side; the long side and the short side are perpendicular to the transverse side; a hypotenuse is set at the junction of the short side and the transverse side, and the hypotenuse and the transverse side are set at an obtuse angle for docking the solar photovoltaic panel; the transverse side is provided with vertically arranged support ribs, and the top of the support ribs is against the solar photovoltaic panel. The present invention has a reasonable structure and is easy to use. The integrated overall structure is convenient for transportation and installation, and the installation of solar photovoltaic panels is convenient through reasonable structural settings. Since the solar photovoltaic panel is used in the open air, it is necessary to provide effective moisture-proof support for it when there is a lot of rain to avoid damage to the accessories. However, it is not convenient to adjust the tilt angle of the solar photovoltaic panel when installing the support, and it is very easy to have serious swings and resonance in a windy environment. At the same time, it cannot be adjusted according to the installation of solar photovoltaic panels of different lengths and widths. Summary of the invention

[0049] The cross beam 303 has a linkage hinged rod 305 hinged on one side thereof and a linkage hinged rod 406 hinged on the other side thereof.

[0050] It should be noted that the shape of the rotating beam 2 307 is a triangular setting, so that the rotating beam 2 307 can improve the stronger supporting force and stability. The rotating beam 2 307, the cross beam 303, the linkage hinged rod 3 305, and the linkage hinged rod 4 306 form a four-link quadrilateral setting. The four-link is a symmetrical four-link setting. The auxiliary connecting plate 300 is provided with connecting holes for easy connection and fixation. The four-link is a universal mechanical transmission form.

[0051] In the present invention, preferably, the linkage hinged rod three 305 and the linkage hinged rod four 306 are hingedly connected to the rotating beam two 307 at the side away from the beam 303, the beam 303 is hingedly connected to the inner side of the threaded connection locking bolt two 302 of the auxiliary fixing frame 301, and the rotating beam two 307 is hingedly connected to the inner side of the threaded connection locking bolt three 309 of the auxiliary fixing frame 301.

[0052] It should be noted that the second locking bolt 302 can lock the hinge between the auxiliary fixing frame 301 and the cross beam 303 , and the third locking bolt 309 can lock the hinge between the auxiliary fixing frame 301 and the second rotating beam 307 .

[0053] In the present invention, preferably, a transmission shaft 6 is fixedly connected to the middle of the crossbeam 303 , and the transmission shaft 6 is driven by the driving device 202 , and the transmission shaft 6 penetrates and is rotatably connected to the main fixing frame 209 and the auxiliary fixing frame 301 .

[0054] It should be noted that a triangular connecting frame is fixedly installed on the inner side of the cross beam 303 , and the transmission shaft 6 is fixed in the middle of the triangular connecting frame.

[0055] In the implementation process, when it is necessary to adjust the angle of the bracket 1 and the bracket 2 4, the driving device 202 is set, and the driving device 202 drives the transmission shaft 6 to rotate along the main fixed frame 209 and the auxiliary fixed frame 301 by a small amplitude, and the transmission shaft 6 rotates and then drives the cross beam 303 to rotate the changed angle, so that the cross beam 303, the linkage hinge rod 305, the linkage hinge rod 4 306, and the rotating beam 2 307 are folded along the auxiliary fixed frame 301 to adjust the angle, thereby achieving a four-link motion, so that the rotating beam 2 307 is tilted, and the two rotating beams 307 are tilted. The sides are equipped with bracket 1 and bracket 2 4 to adjust the angle and thus adjust the inclination angle of the solar panel thereon. When bracket 1 and bracket 2 4 are adjusted, they also lead the rotating beam 1 207, the linked hinged rod 2 206, the linked hinged rod 1 205 and the sandalwood bar 204 to fold and deform along the main fixed frame 209, and then perform a four-link motion. By tightening the locking bolt 3 309, the locking bolt 2 302 and the locking bolt 1 210, the hinge is locked to achieve the purpose of auxiliary self-locking, and the driving device 202 stops driving to achieve the purpose of active self-locking.

[0056] It should be noted that the self-locking property 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 smaller than the equivalent friction angle between the meshing teeth, the mechanism has self-locking property. This self-locking property can prevent the reversal of the worm wheel, thereby limiting the movement of the four-bar linkage. The rotating beam 207, the linkage hinged rod 206, the linkage hinged rod 205 and the sandalwood bar 204 stop the meshing of the worm gear to achieve self-locking of the entire hinge point, and limited locking components are provided at the hinge points of the four-bar linkage, so that the four-bar linkage can move to the specified position and achieve self-locking of the entire hinge point through the cooperation between the locking components and the worm gear.
