Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic power generation technology, and more specifically, it relates to a photovoltaic installation bracket that can adapt to complex terrain. Background Technology

[0002] Photovoltaic mounting brackets are key structures for supporting and fixing solar photovoltaic modules. They can be adapted to different installation scenarios such as rooftops, ground, and water surfaces. They are mostly made of weather-resistant materials such as aluminum alloy and steel, and have wind resistance and load-bearing properties. Existing photovoltaic mounting brackets generally consist of a base frame connected to the ground, support rods, and connectors for assembling and fixing various components.

[0003] Existing application number: CN202410248243.0, this invention discloses a photovoltaic panel mounting bracket, relating to the field of photovoltaic panel installation technology. The mounting bracket includes: a support; and a flipping component mounted on the support. The flipping component is connected to the back of the photovoltaic panel and is located near the tilted end of the photovoltaic panel. Using the support point of the flipping component as a dividing line, the photovoltaic panel is divided into upper and lower parts, with the area of ​​the upper half of the photovoltaic panel being smaller than the area of ​​the lower half. This photovoltaic panel mounting bracket of the present invention adjusts the position of the photovoltaic panel on the rotating block so that the area of ​​the lower half of the photovoltaic panel is larger than that of the upper half. Then, a counterweight adjusts the weight of the upper and lower parts of the photovoltaic panel to restore balance. This allows the panel to gradually tilt downwards as debris accumulates on its surface, eventually cleaning the debris and restoring it to its original shape after further cleaning, thus enabling repeated cleaning of the photovoltaic panel.

[0004] Based on the above, the support structure of photovoltaic mounting brackets is mostly fixed. In complex terrain with undulating ground, it is impossible to flexibly adjust the height of each support point according to the terrain differences. As a result, the bottom of some support points cannot effectively contact the ground, which affects the stability of the bracket. At the same time, due to the installation angle, the angle of the photovoltaic panel is also difficult to receive sunlight well, thus affecting the photoelectric conversion efficiency. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a photovoltaic mounting bracket that can adapt to complex terrain. This solves the problem that most existing photovoltaic mounting brackets have fixed support structures, which cannot flexibly adjust the height of each support point according to the terrain differences in complex terrain with undulating ground. As a result, the bottom of some support points cannot effectively contact the ground, thus affecting the stability of the bracket. At the same time, due to the influence of the installation angle, the angle of the photovoltaic panel is also difficult to receive sunlight well, thus affecting the photoelectric conversion efficiency.

[0006] The purpose and effectiveness of this utility model, which provides a photovoltaic mounting bracket adaptable to complex terrain, are achieved through the following specific technical means: A photovoltaic mounting bracket adaptable to complex terrain includes a main bracket, support tubes, mounting columns, positioning boxes, mounting plates, guide rails, positioning adaptation components, and quick-adjustment components. Four support tubes are provided, and are distributed and fixedly connected to the lower part of the main bracket. Four mounting columns are provided, each inserted into one of the four support tubes. Four positioning boxes are provided, each fixedly connected to the inner bottom of one of the four support tubes. The mounting plate is fixedly connected inside the main bracket. The guide rail is fixedly connected to the upper rear end of the mounting plate. Four sets of positioning adaptation components are provided, each located at the bottom of one of the four support tubes. The quick-adjustment components are located above the guide rails.

[0007] Furthermore, the positioning adaptation component includes: a sliding plate and a pulling member; the sliding plate is slidably connected inside the positioning box; the left end of the pulling member is fixedly connected to the inner side of the sliding plate, and the pulling member is slidably connected to the positioning box.

[0008] Furthermore, the positioning adaptation component also includes: a positioning post and a fixing slot; the positioning post is fixedly connected to the outside of the sliding plate, and the positioning post is slidably connected to the positioning box; the fixing slot is opened on the inner side of the bottom of the support tube, and the positioning post is inserted into the fixing slot.

[0009] Furthermore, the positioning adaptation component also includes: an adjustment slot and a return spring; a positioning post is inserted into the adjustment slot, and multiple adjustment slots are provided, which are distributed inside the mounting post; the outer end of the return spring is fixedly connected to the inner side of the sliding plate, and the inner end of the return spring is fixedly connected to the inside of the positioning box.

[0010] Furthermore, the quick adjustment assembly includes: a slider, a transmission screw, and an operating handwheel; the slider is slidably connected inside the guide rail; the transmission screw is rotatably connected inside the guide rail, and the transmission screw is threadedly connected to the slider; the operating handwheel is coaxially fixedly connected to the rear end of the transmission screw.

[0011] Furthermore, the quick adjustment assembly also includes: a fixed shaft, an adjustment plate, and a connector; the fixed shaft is fixedly connected to the inside of the front end of the main support; the bottom of the adjustment plate is hinged to the top of the slider; two connectors are provided, one in front is hinged to the outside of the fixed shaft, and the other in rear is hinged to the upper end of the adjustment plate.

[0012] Compared with the prior art, the present invention has the following beneficial effects: First, the stability of the support is solved by using the positioning adaptation component. By pulling the puller inward, the height of the mounting column can be adjusted up and down. After the bottom of the mounting column contacts the ground, the puller is released, and the positioning column is re-inserted into the corresponding height fixing slot and adjustment slot to fix the mounting column. This ensures that the bottom of all four mounting columns are in contact with the ground, thus improving the stability of the bracket.

[0013] Secondly, rotating the operating handwheel drives the transmission screw to rotate. Under the guidance of the guide rail, the slider moves back and forth, causing the angle of the adjustment plate hinged to the slider to change, thereby changing the height of the rear end of the photovoltaic panel. This allows for flexible adjustment of the photovoltaic panel angle, enabling it to better receive sunlight and improve photoelectric conversion efficiency.

[0014] This invention allows for flexible adjustment of the installation column height through a positioning adaptation component to ensure stable support, and for flexible adjustment of the photovoltaic panel angle through a quick adjustment component to improve photoelectric conversion efficiency. It effectively overcomes the limitations of complex terrain on photovoltaic installation, enabling the photovoltaic power generation system to be stably deployed in diverse terrains such as mountains and hills. At the same time, it optimizes the light-receiving conditions of the photovoltaic panel, providing strong support for improving the overall efficiency of photovoltaic power generation.

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model. Example 1

[0022] As attached Figure 1 To be continued Figure 5 As shown: This utility model provides a photovoltaic mounting bracket adaptable to complex terrain, including a main bracket 1, support pipes 2, mounting columns 3, positioning boxes 4, mounting plates 6, guide rails 7, and positioning adaptation components; four support pipes 2 are provided, which are distributed and fixedly connected to the bottom of the main bracket 1; four mounting columns 3 are provided, which are respectively inserted into the four support pipes 2; four positioning boxes 4 are provided, which are respectively fixedly connected to the bottom inner side of the four support pipes 2; the mounting plate 6 is fixedly connected to the inside of the main bracket 1; the guide rail 7 is fixedly connected to the upper rear end of the mounting plate 6; four sets of positioning adaptation components are provided, which are respectively set at the bottom of the four support pipes 2.

[0023] The positioning adaptation component includes a sliding plate 5 and a pulling member 502; the sliding plate 5 is slidably connected inside the positioning box 4; the left end of the pulling member 502 is fixedly connected to the inner side of the sliding plate 5, and the pulling member 502 is slidably connected to the positioning box 4.

[0024] The positioning adaptation component also includes: a positioning post 501 and a fixing slot 201; the positioning post 501 is fixedly connected to the outside of the sliding plate 5 and is slidably connected to the positioning box 4; the fixing slot 201 is opened on the bottom inner side of the support tube 2 and the positioning post 501 is inserted into the fixing slot 201.

[0025] The positioning adaptation component also includes: an adjustment slot 301 and a reset spring 503; the positioning post 501 is inserted into the adjustment slot 301, and multiple adjustment slots 301 are provided, which are distributed inside the mounting post 3; the outer end of the reset spring 503 is fixedly connected to the inner side of the sliding plate 5, and the inner end of the reset spring 503 is fixedly connected to the inside of the positioning box 4.

[0026] The specific usage and function of this embodiment are as follows: During use, the bottom of the mounting column 3 is connected to the ground. If the ground is uneven, the bottoms of the four mounting columns 3 will be at different heights. At this time, the pulling member 502 can be pulled inward. One end of the pulling member 502 extends to the outside of the positioning box 4, forming a pull ring structure that is easy to operate. This causes the sliding plate 5 and the positioning column 501 to move inward at the same time. The positioning column 501 disengages from the inside of the fixing slot 201 and the adjusting slot 301. Then, the mounting column 3 can be adjusted up and down. After the bottom of the mounting column 3 contacts the ground, the adjusting slot 301 at the appropriate height inside the mounting column 3 coincides with the fixing slot 201. At this time, the pulling member 502 is released. Under the rebound action of the return spring 503, the positioning column 501 is inserted into the inside of the fixing slot 201 and the adjusting slot 301 at the same time, so that the mounting column 3 is fixed at the appropriate height. The bottoms of all four mounting columns 3 are in contact with the ground, so that the main bracket 1 can be placed more stably on the ground. Example 2

[0027] Based on Example 1, as shown in the appendix Figure 1 To be continued Figure 5 As shown, it also includes a quick-adjustment component, which is located above the guide rail 7.

[0030] The specific usage and function of this embodiment: When the photovoltaic panel is installed, the bottom of the front and rear ends are fixedly connected to the two connecting parts 12 with bolts. If it is found that the photovoltaic panel cannot receive the sun's rays well after installation, the angle needs to be adjusted. At this time, the operating handwheel 901 can be turned. Under the guidance of the guide rail 7, when the operating handwheel 901 drives the transmission screw 9 to rotate, the transmission screw 9 will drive the slider 8 to move back and forth through the threaded transmission mechanism formed together with the slider 8, thereby changing the angle of the adjusting plate 11 and the height of the rear end of the photovoltaic panel, thereby adjusting the angle of the photovoltaic panel to better receive the sun's rays.
