Description

Technical Field

[0001] This utility model relates to the technical field of photovoltaic brackets, and in particular to an adjustable photovoltaic bracket applicable to multiple scenarios. Background Technology

[0002] With the continued growth of global demand for renewable energy, solar energy, as a clean and renewable energy source, is becoming increasingly important. Photovoltaic panels, as key components for converting solar energy into electricity, directly convert sunlight into electrical energy through the photoelectric effect. A complete photovoltaic system typically consists of multiple individual solar cells, which need to be connected in series or parallel in a specific way and undergo rigorous encapsulation to form photovoltaic modules, ensuring their stability and durability under various environmental conditions.

[0003] However, in practical applications, the existing photovoltaic mounting methods have many shortcomings.

[0004] First, most photovoltaic mounting systems are complex in design, large in size, prone to deformation, and heavy. These characteristics increase the difficulty of manufacturing the systems and cause many inconveniences during transportation. The large space occupied by a single system leads to a significant increase in container loading and transportation costs.

[0005] Secondly, once installed, the position and angle of the photovoltaic panels are often difficult to adjust. This fixed installation method limits the photovoltaic panels' ability to adjust their angle optimally according to changes in sunlight, thus affecting the overall power generation efficiency and applicability of the photovoltaic system.

[0006] Furthermore, with technological advancements and the diversification of market demands, the inadequacy of traditional photovoltaic panel installation structures in terms of flexibility and adaptability has become increasingly apparent. These structures struggle to meet the requirements of photovoltaic systems in various application scenarios.

[0007] In view of this, the inventor has designed an adjustable photovoltaic bracket applicable to multiple scenarios, which leads to this invention. Utility Model Content

[0018] Preferably, the sliding tongue is square-shaped and has symmetrical guide slopes at its upper end, with an arc transition between the guide slopes and the adjacent sides of the sliding tongue.

[0019] Preferably, the inner telescopic rod has scale markings distributed along its length on its side wall. The scale markings include several commonly used angle markings. When the angle markings are aligned with the upper edge of the outer adjustment tube, the photovoltaic panel and the bottom frame form an angle with the same angle value as the angle markings.

[0020] Preferably, the inner wall of the inner side is provided with a second connector. The second connector includes an inner wall fixed to the inner side and side walls extending perpendicularly to the outer side away from the inner side along the inner wall and both sides. A second rotating shaft is passed between the two side walls, and the bottom of the outer adjusting tube forms two first rotating shaft holes that cooperate with the second rotating shaft.

[0047] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0048] Existing photovoltaic (PV) mounting solutions are large in size, have many components, and are costly to produce. To address these issues, the photovoltaic mounting solution described in this paper is as follows:

[0049] Please see Figures 1 to 11 This is a multi-scenario applicable adjustable photovoltaic bracket, which is the preferred embodiment of the present invention, comprising:

[0050] The photovoltaic panel 10 is in the shape of a square frame, including an outer frame. The inner side of the frame is used to fix the solar photovoltaic panel 11. After the entire photovoltaic panel 10 is assembled, it is used to directly convert sunlight into electrical energy through the photoelectric effect.

[0051] The bottom frame 20 is a square frame formed by welding four square rods end to end. Two of the square rods are the inner side 22 and the outer side 21, respectively. The outer side 21 is rotatably connected to the bottom edge of the photovoltaic panel 10 by a hinge 23.

[0052] Specifically, the hinge 23 includes an upper piece 231 and a lower piece 232 that are hinged to each other. The upper piece 231 is fixed at the lower end face of the overall frame, and the lower piece 232 is fixed at the outer side wall of the outer side 21. The hinge position of the hinge 23 is set to be opposite to the connection position of the photovoltaic panel 10 and the bottom frame 20, so that when the photovoltaic panel 10 is rotated downward around the hinge 23 to the lowest position, it can fit exactly with the upper end face of the bottom frame 20. At this time, there is only a gap between the bottom frame 20 and the photovoltaic panel 10 through the upper piece 231 of the hinge 23, thereby maximizing the volume occupied when the whole is folded.

[0053] The adjustment bracket 30 has two sets and is distributed at both ends of the inner side 22 along its length. Each adjustment bracket 30 includes an outer adjustment tube 31 and an inner telescopic rod 32 that is slidably inserted into the outer adjustment tube 31 from bottom to top. The bottom of the outer adjustment tube 31 is hinged to the inner side of the inner side 22, and the inner telescopic rod 32 is hinged to the side of the photovoltaic panel 10 away from the outer side 21.

[0054] Adjustment mechanism 40 is used to fix or release the relative position of the outer adjustment tube 31 and the inner telescopic rod 32.

[0055] Preferably, in this embodiment, the outer adjusting tube 31 is a hollow rectangular sleeve, and the inner telescopic rod 32 is a hollow rectangular sleeve that can be nested with the outer adjusting tube 31. The upper side of the inner telescopic rod 32 is provided with an adjusting groove 321 that penetrates into its interior and is distributed along its length.

[0056] Preferred, such as Figure 5 As shown, a pair of sheet-like fixing ears 322 are symmetrically arranged at the end of the inner telescopic rod 32 away from the outer regulating pipe 31 and facing the opening direction of the regulating groove 321. A first rotating shaft 323 is inserted between the two fixing ears 322. A first connector 50 is detachably fixed to the edge of the photovoltaic panel 10 and located on its bottom side. The first connector 50 has a bushing end 52 that can be rotatably sleeved with the first rotating shaft 323.

[0057] Specifically, such as Figure 5 As shown, the first connector 50 includes a straight plate-shaped connecting end 51 and a cylindrical bushing end 52 with a notch 53 that can prevent the first rotating shaft 323 from coming out. One side of the notch 53 of the bushing end 52 is integrally connected to the connecting end 51. The connecting end 51 has a first locking hole 54 through it. The bottom surface of the photovoltaic panel 10 has a second locking hole 55 opposite to the first locking hole 54. In this embodiment, by aligning the first locking hole 54 on the connecting end 51 with the second locking hole 55 and locking the corresponding bolts in the locking throat, the first connector 50 is attached and fixed to the bottom surface of the photovoltaic panel 10. The bushing end 52 extends beyond the overall frame of the photovoltaic panel 10, so that when the photovoltaic panel 10 is covered on the bottom frame 20, it will not be blocked or interfered by the bushing end 52, thus maintaining the minimum volume occupation of the overall folding.

[0058] Preferred, such as Figure 6 , 8 As shown, the adjustment mechanism 40 includes a sliding tongue block 41 and a first locking bolt 42. The sliding tongue block 41 is slidably disposed in the hollow area of ​​the inner telescopic rod 32 and has a first fixing screw hole 43 on the side facing the adjustment groove 321 that can be threadedly connected with the first locking bolt 42. The upper end of the outer adjustment tube 31 away from the bottom frame 20 has a third locking hole 311 that cooperates with the first fixing screw hole 43.

[0059] During the adjustment process, by loosening the first locking bolt 42, the sliding tongue 41 and the hollow inner wall 61 of the inner telescopic rod 32 are in a state of relative sliding. The photovoltaic panel 10 is adjusted up and down according to the required angle, so that the inner telescopic rod 32 moves up and down relative to the outer adjustment tube 31. At this time, the sliding tongue 41 and the first locking bolt 42 are still not disengaged and are in a relatively fixed state under the restriction of the first locking bolt 42. After the angle of the photovoltaic panel 10 is adjusted, the first locking bolt 42 is tightened again, so that the sliding tongue 41 abuts against the inner side wall of the inner telescopic rod 32, so that the relative position of the inner telescopic rod 32 and the outer adjustment tube 31 is fixed again, and the angle adjustment process of the photovoltaic panel 10 is finally completed. Through the setting of the adjustment mechanism 40, the adjustment process of the photovoltaic panel 10 can be made simpler and faster. Compared with the existing angle adjustment method of photovoltaic bracket (such as the pin-type adjustment), it does not require disassembly of parts, which is more convenient and faster.

[0060] Preferred, such as Figure 6 As shown, the sliding tongue block 41 is square in shape and has a guide slope 411 symmetrically arranged at its upper end. There is an arc transition between the guide slope 411 and the adjacent side of the sliding tongue block 41. Thus, through the structure of the guide slope 411 and the arc transition, the extension and retraction adjustment process of the inner telescopic rod 32 and the outer adjusting tube 31 can be smoother, avoiding scratches and wear of the inner telescopic rod 32 too quickly due to the adjustment angle, and fully extending the overall service life.

[0061] Preferred, such as Figure 6 As shown, the inner telescopic rod 32 has scale markings distributed along its length on its side wall. The scale markings include several commonly used angle markings 33. When the angle markings 33 are aligned with the upper edge of the outer adjustment tube 31, the photovoltaic panel 10 and the bottom frame 20 form an angle with the same angle value as the angle markings 33.

[0062] Specifically, in this embodiment, the angle markers 33 include commonly used 20°, 30°, 40°, 50°, and 60°, and are located on the side of the two inner telescopic rods 32 that are far apart from each other. The spacing between the angle markers 33 is not equal. When the angle marker 33 is aligned with the uppermost position of the outer adjustment tube 31, the angle between the photovoltaic panel 10 and the bottom frame 20 corresponds exactly to the angle data corresponding to the angle marker 33. By pre-setting commonly used angle markers 33, users can quickly adjust the angle of the photovoltaic panel 10, thereby improving the convenience of photovoltaic bracket installation and use, and greatly reducing the usage threshold.

[0063] Preferred, such as Figure 7 As shown, the inner side wall of the inner side 22 is provided with a second connector 60. The second connector 60 includes an inner wall 61 fixed to the inner side 22 and side walls 62 extending vertically along the inner wall 61 and both sides toward the outer side away from the inner side 22. A second rotating shaft 63 is passed between the two side walls 62. The bottom of the outer adjusting tube 31 passes through to form two first rotating shaft holes 312 that cooperate with the second rotating shaft 63.

[0064] In this embodiment, the extension length of the side wall 62 is greater than the length of the external adjustment tube 31 on the same side, so that the external adjustment tube 31 can rotate smoothly around the second rotating shaft 63, thus realizing the adjustment process of the photovoltaic panel 10.

[0065] Preferred, such as Figure 9 As shown, it also includes an inverter bracket 70, which is a U-shaped long rod. The middle part of the inverter bracket 70 is provided with several first mounting holes 71 for fixing the inverter 78, and the two ends of the inverter bracket 70 extend outward symmetrically to form connecting pieces 72. The connecting pieces 72 and the body of the inverter bracket 70 enclose a receiving space 73 that is adapted to the inner telescopic rod 32. A second mounting hole 74, which is elongated and extends along the length of the connecting piece 72, is provided through the connecting piece 72. A connecting block 75 is slidably provided in the hollow area of ​​the inner telescopic rod 32. A second fixing screw hole 76 is provided on the side of the connecting block 75 near the opening of the adjustment groove 321. When the connecting piece 72 covers the inner telescopic rod 32, the second mounting hole 74 at least partially covers the second fixing screw hole 76. The inverter bracket 70 is locked and fixed to the second fixing screw hole 76 after the second locking bolt 77 passes through the second mounting hole 74 and the adjustment groove 321 in sequence.

[0066] In this embodiment, the opening of the inverter bracket 70 faces the area covered by the photovoltaic panel 10. The first mounting hole 71 is an elongated slotted hole with three holes, centrally located in the middle of the inverter bracket 70. When installing the inverter bracket 70, simply overlap the connecting piece 72 with the adjusting groove 321 side of the inner telescopic rod 32, pre-insert the connecting block 75 into the hollow area of ​​the inner telescopic rod 32, insert the second fixing bolt into the second mounting hole 74 of the connecting piece 72, and then pass it through the adjusting groove 321 and the second mounting hole 74 of the connecting block 75. After the screw hole 76 is locked in place, the connecting block 75 is pulled toward the connecting piece 72 and pressed against the inner wall of the inner telescopic rod 32, thus fixing the end of the inverter bracket 70 to the inner telescopic rod 32. The other end of the inverter bracket 70 can be fixed by repeating the above process. The elongated second mounting hole 74 provides a certain margin of error when installing the other end of the inverter bracket 70, eliminating the need for perfect alignment between the connecting piece 72 and the wall of the inner telescopic rod 32, further improving the ease of installation.

[0067] Preferred, such as Figure 10 , 11 As shown, it also includes heightening brackets 80 located on both sides of the bottom of the base frame 20. The heightening brackets 80 include two legs 81 vertically located at both ends of the side of the base frame 20, a reinforcing rod 82 detachably fixed between the two legs 81, and a reinforcing plate 83 inclinedly fixed between the top of the legs 81 and the outer wall of the base frame 20.

[0068] In this embodiment, when the heightening bracket 80 is not installed, the inverter 78 can be installed between the two inner telescopic rods 32 through the inverter bracket 70. After the heightening bracket 80 is installed, the inverter 78 can be locked by making a hole in one of the reinforcing plates 83, so as to avoid the addition of the heightening bracket 80 affecting the ease of installation of the inverter 78.

[0069] The beneficial effects of this embodiment are as follows:

[0070] This patent reduces costs and facilitates installation by improving the bottom frame structure; by adjusting the angle mark 33 on the inner telescopic rod 32, it can be flexibly moved according to sunlight and seasons to adapt to different angles of light; by pulling out the inner telescopic rod 32 and laying it flat, it can achieve a ground-folding function. The photovoltaic bracket of this utility model has the advantages of stable structure, convenient angle adjustment, easier carrying, and lower cost.

[0071] In summary, this utility model provides a photovoltaic support structure that is simple in structure, easy to install, applicable to multiple scenarios, and can effectively improve power generation efficiency.
