Description

Technical Field

[0001] The utility model relates to the field of photovoltaic brackets, and particularly relates to a photovoltaic bracket. Background Art

[0002] A photovoltaic bracket refers to a support structure that arranges and fixes photovoltaic modules at a certain orientation, angle and fixed spacing according to the specific geographical location, climate and solar energy resource conditions of the construction of a photovoltaic power generation system.

[0003] The existing photovoltaic brackets mainly use support columns to fix the support rods, and place and install photovoltaic panel frames on the support rods. However, the angle of the support rods cannot be adjusted, so the angle of the photovoltaic panels cannot be adjusted, resulting in poor adaptability. Moreover, the stability of adjacent support rods is also poor, and it is easy to shake when blown by strong winds. Summary of the Utility Model

[0004] In order to solve the above existing problems, the utility model provides a photovoltaic bracket.

[0005] The utility model is realized through the following technical solutions:

[0006] A photovoltaic bracket includes support columns on both sides. The top of the support column is hinged with a rotatable support rod. The lower parts of the front and rear ends of the support rod are respectively hinged and fixed to the support column through a front adjuster and a rear adjuster. The front adjusters and rear adjusters on both sides are firmly connected through an adjusting pull rod. Rotating the adjusting pull rod drives the front adjuster and the rear adjuster to open and close to realize the angle adjustment of the support rod.

[0007] Further optionally, the front adjuster and the rear adjuster include two scissors arms in an "eight" shape up and down. The two sides of the two scissors arms are hinged through a transverse connecting block, and the two connecting rods of each scissors arm are hinged and fixed through a longitudinal connecting block.

[0008] Further optionally, the two longitudinal connecting blocks of the front adjuster and the rear adjuster are respectively hinged and fixed to the support rod and the support column.

[0009] Further optionally, the adjusting pull rod includes a rotating connecting rod, and threaded rods connected to the two transverse connecting blocks of the front adjuster and the rear adjuster are connected to both sides of the rotating connecting rod.

[0010] Further optionally, the threaded directions of the threaded rods on both sides of the rotating connecting rod are opposite.

[0011] Compared with the existing technologies, the beneficial effects of the present utility model are as follows: The structure of the present utility model is simple and the operation is convenient. Only by simultaneously rotating the front and rear adjusting pull rods to drive the corresponding pair of front adjusters and rear adjusters to perform telescopic and opening actions, the inclination angle of the support rod for mounting the photovoltaic panel frame on the upper part can be adjusted. Moreover, the horizontal adjusting pull rod realizes the stable support of the support rod, avoiding the shaking and deformation of the support rod due to force. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The present utility model will be further described in detail below in conjunction with the drawings and the detailed description of the embodiments:

[0018] As Figure 1 、 2 、and 3 show, a photovoltaic bracket includes support columns 1 on both sides. The top of the support column 1 is hinged with a rotatable support rod 2. A photovoltaic panel frame is installed on the upper part of the support rod 2. The lower parts of the front and rear ends of the support rod 2 are respectively hinged and fixed to the support column 1 through a front adjuster 3 and a rear adjuster 4. The front adjusters 3 and the rear adjusters 4 on both sides are firmly connected through an adjusting pull rod 5 respectively. Rotating the adjusting pull rod 5 drives the front adjuster 3 and the rear adjuster 4 to open and close to realize the angle adjustment of the support rod 2. When adjusting the front adjuster 3 and the rear adjuster 4, it is necessary to ensure that one is in an open state and the other is in a contracted state to realize the adjustment of the inclination angle of the support rod 2.

[0019] As Figure 2 shows, the front adjuster 3 and the rear adjuster 4 include two scissor arms 6 in an "eight" shape up and down (the overall structure of the front adjuster 3 and the rear adjuster 4 is equivalent to that of an automotive scissor jack). The two side ends of the two scissor arms 6 are hinged through a horizontal connection block 8. The two connecting rods of each scissor arm 6 are hinged and fixed through a longitudinal connection block 7.

[0020] As Figure 2As shown in the figure, the two longitudinal connecting blocks 7 of the front regulator 3 and the rear regulator 4 are respectively hinged and fixed to the support rod 2 and the support column 1.

[0021] As Figure 2 , 4 shown in the figure, the adjusting pull rod 5 includes a rotating link 10. The rotating link 10 is arranged as a polygonal prism, which is convenient for the wrench to turn. The two sides of the rotating link 10 are connected with threaded rods 9 that are synchronously threadedly connected to the two transverse connecting blocks 8 of the front regulator 3 and the rear regulator 4. The threaded rods 9 threadedly connected to the two transverse connecting blocks 8 are provided with two threads with different helix directions. In this way, when the threaded rod 9 rotates, the pair of two transverse connecting blocks 8 can be moved to open or contract.

[0022] The threaded rods 9 on both sides of the rotating link 10 have opposite thread helix directions. In this way, when the threaded rods 9 on both sides of the rotating link 10 are rotated, the corresponding regulators can perform the same actions.

[0023] The implementation principle of an embodiment of a photovoltaic bracket in this application is as follows:

[0024] When adjusting the angle of the support rod 2 for placing and installing the photovoltaic panel, two people simultaneously use an open-end wrench to clamp into the rotating link 10 of the front and rear adjusting pull rods 5, and rotate the rotating link 10 in different directions respectively. The rotating link 10 drives the threaded rods 9 on both sides to rotate. The rotating threaded rods 9 perform threaded transmission on a pair of transverse connecting blocks 8 of the front regulator 3 and the rear regulator 4 on both sides, realizing the opening or contraction of a pair of two transverse connecting blocks 8 (the rotating link 10 rotates forward to open and rotates backward to contract);

[0025] When the two transverse connecting blocks 8 of the front regulator 3 contract, the included angle between the upper and lower scissor arms 6 of the front regulator 3 becomes smaller, and the front end of the support rod 2 is lifted. At this time, the two transverse connecting blocks 8 of the rear regulator 4 are in an open state, and the included angle between the two scissor arms 6 of the rear regulator 4 becomes larger, and the rear end of the support rod 2 is lowered. In this way, the inclination angle of the entire support rod 2 will be adjusted larger. When it is necessary to adjust the inclination angle of the support rod 2 smaller, reverse operation can be performed;

[0026] At the same time, the two transversely connected adjusting pull rods 5 realize the stable connection of the front regulator 3 and the rear regulator 4 on both sides, restricting the shaking of the front regulator 3 and the rear regulator 4 on both sides due to force, thereby ensuring the stability of the upper-connected support rod 2.
