Description

Technical Field

[0001] The present application relates to the technical field of rooftop photovoltaic power generation, and in particular to a flexible rooftop photovoltaic bracket. Background Art

[0002] A photovoltaic power generation system is a device that uses solar photovoltaic panels to convert sunlight into electrical energy. It is installed on the roof of a building to maximize the use of solar energy. It is usually composed of photovoltaic panels, brackets, inverters and distribution systems. The photovoltaic bracket plays an important role in carrying and supporting the photovoltaic panels, and its angle has a direct impact on the light absorption efficiency of the photovoltaic panels.

[0003] There is a huge demand for power generation in factories, and the factory roof area is large, which is very suitable for installing photovoltaic power generation systems. Most factory roofs are colored steel tile roofs. The traditional installation method of photovoltaic power generation systems is to lay photovoltaic panels flat according to the angle of the colored steel tile roof. The light absorption efficiency of this laying method is relatively low, especially for photovoltaic systems installed on the shady side of the roof. The power generation efficiency of photovoltaic panels still has room for improvement.

[0004] The existing patent discloses a photovoltaic bracket, which is provided with a front support member and a rear support member. The support member includes a support rod. The lower end of the support rod is connected to a clamp for clamping the ridges of the color steel tile roof. The upper end of the support rod is connected to a beam for supporting the photovoltaic panel. The support rod is fixedly connected to the clamp and the beam. By controlling the length of the front and rear support rods, a height difference is created between the front and rear support members, thereby forming an angle between the beam and the horizontal plane to match the lighting requirements of the shaded side.

[0005] However, in this method, after processing and preparation, since the connection angle and length of the support rod cannot be adjusted, the height difference between the front and rear supports remains unchanged, and the lighting angles in different regions and seasons are different. Although the fixed beam inclination angle can guarantee a certain conversion efficiency, it cannot adjust the specific orientation of the photovoltaic panel according to actual needs to further improve the light energy conversion efficiency, and there is still room for optimization. Utility Model Content

[0006] In order to improve the adaptability of the inclination angle of the photovoltaic bracket to different light angles, the present application provides a flexible roof photovoltaic bracket.

[0007] The flexible roof photovoltaic bracket provided in this application adopts the following technical solution:

[0008] A flexible roof photovoltaic bracket comprises a front bracket and a rear bracket, each of the front bracket and the rear bracket comprises an upper L-shaped angle plate, a clamp rotatably arranged at the lower end of the upper L-shaped angle plate, a crossbeam connected to the upper end of the upper L-shaped angle plate, and a photovoltaic panel pressing block detachably connected to the upper end of the crossbeam; the rear bracket also comprises an extension plate rotatably connected to the upper L-shaped angle plate at the upper end and a support plate fixed to the clamp at the lower end, a slide groove is provided on the plate surface of the support plate along the length direction of the support plate, the lower end of the extension plate is slidably connected to the slide groove, and the extension plate is detachably connected with a locking bolt.

[0009] By adopting the above technical solution, the photovoltaic panels are supported by beams, and the inclination angles of the beams supported by each are adjusted by setting a rotatable front bracket and a rear bracket. At the same time, the support height of the rear bracket can be changed by adjusting the length of the extension plate extending out of the support plate, thereby realizing the adjustment of the height difference between the front and rear brackets; the support inclination angle of the photovoltaic bracket is changed by adjusting the inclination angle and the height difference. When installing the photovoltaic bracket, the direction of the photovoltaic bracket can be adjusted according to the actual local lighting conditions and the actual lighting conditions of the season, thereby improving the light absorption efficiency of the photovoltaic panel and thus improving the energy conversion efficiency of the photovoltaic panel.

[0010] Optionally, at least two slide grooves are vertically spaced apart, a sliding block for inserting the slide groove is protruding from the lower end of the extension plate, and a plurality of insertion holes for inserting the locking bolts are spaced apart along the length direction of the support plate on the surface of the support plate.

[0011] By adopting the above technical solution, the extension plate is slid along the slide groove to the target height, and then the locking bolt is used to lock and limit the height, which is simple and easy.

[0012] Optionally, the extension plate is rotatably connected to the support plate.

[0013] By adopting the above technical solution, under the premise that the extension plate is rotatably connected to the upper L-shaped angle plate, the mobility of the extension plate is further improved, thereby further meeting the demand for fine adjustment of the inclination angle.

[0014] Optionally, the slide groove vertically penetrates the plate surface of the support plate, and the locking bolt passes through the extension plate and the support plate at the same time.

[0015] Optionally, the front bracket further comprises a lower L-shaped angle plate rotatably connected to the upper L-shaped angle plate, and the lower L-shaped angle plate is connected to the clamp.

[0016] By adopting the above technical solution, the double L-shaped angle plates are installed in an inverted manner, and the rotational connection between the upper L-shaped angle plate and the clamping member can be achieved without adding new types of processed parts. The processing is convenient and the solution is simple and easy.

[0017] Optionally, an anti-skid ridge is convexly provided on the upper end surface of the clamp, and a side of the lower L-shaped angle plate close to the clamp abuts against the anti-skid ridge.

[0018] By adopting the above technical solution, the anti-skid ridges enhance the stability of the fixation of the lower L-shaped angle plate.

[0019] Optionally, the upper plate surface of the upper L-shaped angle plate is detachably connected with a T-bolt, and the lower end of the crossbeam is formed with a limiting groove for embedding the T-bolt.

[0020] In summary, the present application includes at least one of the following beneficial technical effects:

[0021] 1. Use beams to support photovoltaic panels, and adjust the inclination angles of the beams supported by each by setting rotatable front and rear brackets. At the same time, the support height of the rear bracket can be changed by adjusting the length of the extension plate extending out of the support plate, thereby adjusting the height difference between the front and rear brackets. Use the coordination of adjusting the inclination angle and adjusting the height difference to change the support inclination angle of the photovoltaic bracket. When installing the photovoltaic bracket, adjust the direction of the photovoltaic bracket according to the actual local lighting conditions and the actual lighting conditions of the season, thereby improving the light absorption efficiency of the photovoltaic panel and thus improving the energy conversion efficiency of the photovoltaic panel.

[0027] The following is combined with Figure 1-4 This application is described in further detail.

[0028] Example 1

[0029] The present application embodiment discloses a flexible roof photovoltaic bracket. Figure 1 The flexible roof photovoltaic bracket includes a front bracket 1 and a rear bracket 2 arranged front and rear. The length of the rear bracket 2 is longer than the front bracket 1, so that a height difference is formed between the two. The upper end of the photovoltaic bracket supports a photovoltaic panel.

[0030] Reference Figure 2 and Figure 3 The front bracket 1 includes a photovoltaic panel pressing block 11, a crossbeam 12, an upper L-shaped angle plate 13, a lower L-shaped angle plate 14, and a clamp 15 for clamping the convex edge of the color steel tile roof, which is arranged from top to bottom. The clamp 15 can be an angle clamp 15 or a vertical lock edge clamp 15. The present application takes the angle clamp 15 as an example. The crossbeam 12 is used to support the photovoltaic panel. When installing the photovoltaic panel, the photovoltaic panel pressing block 11 is inserted into the installation hole of the photovoltaic panel, and the photovoltaic panel pressing block 11 is passed through the bolt and locked inside the crossbeam 12, so that the photovoltaic panel is fixed on the crossbeam 12, and the front and rear ends of the photovoltaic panel are respectively fixedly connected to the front and rear crossbeams 12 by the photovoltaic panel pressing block 11.

[0031] The lower end surface of the cross beam 12 is concave and forms a limiting groove 121. A T-bolt 16 is inserted into the limiting groove 121. The T-bolt 16 passes through the horizontal plate surface of the upper L-shaped angle plate 13 and is locked, so that the cross beam 12 is fixedly connected to the upper L-shaped angle plate 13. The upper L-shaped angle plate 13 and the lower L-shaped angle plate 14 are assembled by facing each other, and the vertical plate of the upper L-shaped angle plate 13 and the vertical plate of the lower L-shaped angle plate 14 are rotatably connected by an external hexagonal bolt group, that is, the angle between the upper L-shaped angle plate 13 and the lower L-shaped angle plate 14 is variable. In addition, the horizontal plate of the lower L-shaped angle plate 14 is fixed to the upper end of the clamp 15 by an external hexagonal bolt group inserted vertically into the lower L-shaped angle plate 14. The upper end surface of the clamp 15 is integrally formed with an anti-slip ridge 151, and the lower end surface of the lower L-shaped angle plate 14 abuts against the anti-slip ridge 151.

[0032] Reference Figure 3 The difference between the rear bracket 2 and the front bracket 1 is that the lower L-shaped angle plate 14 is replaced by an extension plate 21 and a support plate 22. The rest of the structure and principle are the same as those of the front bracket 1 and will not be described here. The upper end of the extension plate 21 is rotatably connected to the lower end of the upper L-shaped angle plate 13 by an external hexagonal bolt group, and the lower end of the support plate 22 is detachably connected to the upper end of the clamp 15 by an external hexagonal bolt group.

[0033] The surface of the support plate 22 is provided with a slide groove 221 along the length direction of the support plate 22, and the lower end of the extension plate 21 is slidably connected in the slide groove 221, and the surface of the extension plate 21 is detachably connected with a locking bolt 23 that is inserted into both the extension plate 21 and the support plate 22. The locking bolt 23 can be used to fix the relative position of the extension plate 21 and the support plate 22.

[0034] In Example 1 of the present application, only a slide groove 221 is opened in the middle part of the support plate 22, and the slide groove 221 vertically penetrates the plate surface of the support plate 22. The locking bolt 23 passes through the slide groove 221 and is locked, so that the extension plate 21 is rotatably connected to the support plate 22. Under the premise that the extension plate 21 is rotatably connected to the upper L-shaped angle plate 13, the activity of the extension plate 21 is further improved, thereby further meeting the needs of fine-tuning the inclination angle.

[0035] The implementation principle of a flexible roof photovoltaic bracket in the embodiment of the present application is: using the beam 12 and the photovoltaic panel block 11 to support and fix the photovoltaic panel, and adjusting the inclination angle of the respectively supported beam 12 by setting a rotatable upper L-shaped angle plate 13 and an extension plate 21. At the same time, the support height of the rear bracket 2 can be changed by adjusting the length of the extension plate 21 extending out of the support plate 22, thereby realizing the adjustment of the height difference between the front and rear brackets 2.

[0036] By adjusting the tilt angle and the height difference, the support inclination angle of the photovoltaic bracket can be changed. When installing the photovoltaic bracket, the direction of the photovoltaic bracket can be adjusted according to the actual local lighting conditions and the actual lighting conditions of the season to improve the light absorption efficiency of the photovoltaic panel.

[0037] Example 2

[0038] Reference Figure 4 The difference between the flexible roof photovoltaic bracket disclosed in Example 2 of the present application and Example 1 is that the matching method of the extension plate 21 and the support plate 22 is different, and the other structures and principles are the same as those in Example 1.

[0039] In the second embodiment of the present application, the slide groove 221 does not penetrate the plate surface of the extension plate 21. At least two slide grooves 221 are arranged at intervals on the left and right sides of the plate surface of the extension plate 21. The present application takes two slide grooves as an example. The left and right sides of the lower end of the extension plate 21 are integrally formed with a slide block 211, and the slide block 211 is inserted into the slide groove 221.

[0040] The surface of the support plate 22 is provided with a plurality of insertion holes 222 for inserting the locking bolts 23 at intervals along the length direction of the support plate 22, and the insertion holes 222 are provided between adjacent slide grooves 221. The extension plate 21 is slidably moved, and the locking bolts 23 are inserted into the extension plate 21 and the target insertion holes 222 in sequence, so that the length of the extension plate 21 extending out of the support plate 22 can be adjusted.

[0041] The implementation principle of a flexible rooftop photovoltaic bracket in Example 2 of the present application is the same as that in Example 1 and will not be repeated here.

[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
