[0002] Photovoltaics generally refers to photovoltaic (PV) power generation systems. A PV power generation system, or simply PV, is a power generation system that uses the photovoltaic effect of photovoltaic cells to directly convert solar radiation energy into electrical energy. The energy of a PV power generation system comes from inexhaustible solar energy, making it a clean, safe, and renewable energy source. The PV power generation process does not pollute the environment or damage the ecosystem. PV power generation systems are divided into stand-alone PV systems and grid-connected PV systems. A PV power generation system consists of equipment such as solar cell arrays, battery banks, charge / discharge controllers, inverters, AC distribution cabinets, and solar tracking control systems. During the installation and use of PV panels, PV brackets are needed to install and fix the PV panels.

[0025] Example

[0026] Please see Figures 1-4 One embodiment of this utility model is a folding photovoltaic bracket, which includes a mounting rod 1. Several sets of mounting rods 1 are provided, and adjacent sets of mounting rods 1 are connected by a scissor-type telescopic frame. A photovoltaic panel 11 is rotatably connected to the mounting rod 1.

[0027] The scissor-type telescopic frame includes a first folding rod 2 and a second folding rod 3. The center of the first folding rod 2 and the center of the second folding rod 3 are rotatably connected. Both ends of the first folding rod 2 and the second folding rod 3 are rotatably connected to sliders 5, which are slidably connected to the mounting rod 1.

[0028] The mounting rod 1 has a reversing rod 10 rotatably connected to both ends, and a photovoltaic panel 11 is fixedly connected to the reversing rod 10.

[0029] Limiting blocks 6 are provided at both ends of the mounting rod 1.

[0030] The two ends of the limiting rope 4 are fixedly connected between two adjacent sets of mounting rods 1.

[0031] A limiting groove 12 is provided on the side wall of the reversing rod 10 near the mounting rod 1. The limiting groove 12 is a 1 / 4 arc-shaped groove. A limiting rod 13 is slidably connected in the limiting groove 12, and the limiting rod 13 is fixedly connected to the mounting rod 1.

[0032] A screw 8 is rotatably connected inside the mounting rod 1. A threaded sleeve 7 is threadedly connected to the screw 8. The threaded sleeve 7 is slidably connected inside the mounting rod 1 and is fixedly connected to the slider 5.

[0033] The different screws 8 located at both ends of the mounting rod 1 have different thread directions.

[0034] The screw 8 is fixedly connected to the reversing rod 10.

[0035] A reducer 9 is provided between the screw 8 and the reverse rod 10, and the screw 8 is connected to the reverse rod 10 through the reducer 9.

[0036] The reducer 9 includes a gear ring 93, a central gear 91 is provided at the center of the gear ring 93, and a transmission gear 92 is provided between the central gear 91 and the gear ring 93. The transmission gear 92 meshes with the central gear 91 and the gear ring 93.

[0037] The gear ring 93 is fixedly connected to the mounting rod 1, the transmission gear 92 is rotatably connected to the reversing rod 10, and the center gear 91 is fixedly connected to the screw 8.

[0038] The working principle and beneficial effects of the above scheme are as follows:

[0039] This application designs the bracket to be foldable, which can be folded during transportation, greatly reducing the space occupied after folding and making transportation convenient;

[0040] When folded, the gap between adjacent mounting rods 1 is reduced, causing the first folding rod 2 and the second folding rod 3 to rotate. The two ends of the first folding rod 2 and the second folding rod 3 move towards the end of the mounting rod 1, driving the threaded sleeve 7 to move towards the two ends of the mounting rod 1, driving the screw 8 to rotate. Through the reversing rod 10, the photovoltaic panel 11 is moved out of its original position (between two adjacent sets of mounting rods 1) and rotated to above the mounting rod 1 (90° different from its original position). After the gap between adjacent mounting rods 1 is shortened to fit together, the photovoltaic panel 11 also fits together, greatly reducing the space occupied, which facilitates subsequent transportation.

[0041] When unfolded, the interval between adjacent mounting rods 1 is increased, and the two ends of the first folding rod 2 and the second folding rod 3 move towards the middle of the mounting rod 1, driving the threaded sleeve 7 to move towards the middle of the mounting rod 1, driving the screw 8 to rotate, and driving the photovoltaic panel 11 back to its original position (between two adjacent sets of mounting rods 1) through the reversing rod 10. At this time, the photovoltaic panel 11 faces upward, which facilitates photoelectric conversion.

[0042] The setting of limiting rope 4, limiting block 6, limiting slide 12, and limiting rod 13 during the unfolding and folding process ensures that the rotation angle of the reversing rod 10 is always kept within the limit, avoiding damage to the photovoltaic panel 11 caused by excessive movement.

[0043] The speed reducer 9 reduces the rotational speed of the screw 8, so that after the screw 8 rotates multiple times, the reverse rod 10 only rotates 1 / 4 turn.

[0044] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
