Description

Technical Field

[0001] This utility model relates to the field of photovoltaic panel mounting bracket technology, specifically a photovoltaic panel wind-resistant bracket. Background Technology

[0002] With the accelerated development of the global new energy industry, the scale of photovoltaic power plant construction continues to expand. Since photovoltaic panels are installed outdoors, they are often exposed to strong winds during use. If the wind resistance of the photovoltaic panels is not up to standard, it can easily lead to the photovoltaic panels overturning and being damaged, causing safety accidents or property losses. As the core structure supporting the photovoltaic panels, the performance of the photovoltaic support system directly affects the power generation efficiency, safety and service life of the photovoltaic system.

[0003] A search revealed a Chinese patent with publication number CN220544936U that discloses a wind-resistant support for solar panels. By setting up a fixing plate, a wind guide plate, a solar panel, and an electric actuator, it achieves the effect of improving the ability of solar panels to resist strong winds, protecting the solar panels, and also facilitating the adjustment of the solar panel's angle of attack. The solar panel, the fixing plate, and the two wind guide plates form a rhomboid wind-guiding structure, which greatly reduces the impact of strong winds on the solar panels. Furthermore, the electric actuator can drive the solar panel to rotate, adjusting the angle of attack of the solar panel.

[0004] In the aforementioned literature, existing photovoltaic panel wind-resistant supports require manual control of the extension and retraction of an electric push rod via an adjustment switch to adjust the photovoltaic panel's angle of attack, making it impossible to adaptively adjust to wind speed, resulting in inconvenience and low ease of operation. Therefore, a photovoltaic panel wind-resistant support is proposed to address these issues. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, and addressing the problem that existing photovoltaic panel wind-resistant supports cannot adaptively adjust to wind speed, resulting in inconvenience and low ease of operation, this utility model proposes a photovoltaic panel wind-resistant support.

[0006] The technical solution adopted by this utility model to solve its technical problem is: the photovoltaic panel wind-resistant support of this utility model includes a bearing plate, a plurality of first sleeves arranged horizontally are fixedly connected through the bearing plate, a first annular baffle is fixedly connected to the top port of the plurality of first sleeves, a first sliding rod is slidably arranged through the hole in the middle of the first annular baffle, and a top beam is fixedly connected to the top of the plurality of first sliding rods.

[0007] Two No. 2 sleeves are fixedly connected to both sides of the bearing plate. A No. 2 annular baffle is fixedly connected to the end of each No. 2 sleeve. A No. 2 sliding rod is slidably arranged inside each No. 2 annular baffle. A side beam is fixedly connected between the ends of the No. 2 sliding rods located on the same side.

[0008] Multiple No. 3 sleeves are rotatably connected to both sides of the top beam. A No. 3 sliding rod is slidably installed in the port of each of the multiple No. 3 sleeves. The ends of the No. 3 sliding rods located on the same side are rotatably connected to the side beam on the corresponding side. The upper part of the No. 3 sleeves located on the same side is fixedly connected to the mounting plate.

[0009] A limiting plate is fixed to the end of the first sliding rod located inside the first sleeve, and a spring is provided inside the first sleeve and below the first limiting plate.

[0010] Preferably, a second rotating seat is rotatably installed on both sides of the top beam, a first rotating seat is rotatably installed on both side beams, a base plate is fixedly connected to the bottom ends of multiple first sleeves, and the spring is located on the upper part of the base plate.

[0011] Preferably, the bearing plate is provided with a No. 4 sleeve fixedly connected to both sides of the No. 2 sleeve, and a nut is rotatably installed at the port of the No. 4 sleeve. A threaded rod is threadedly connected to the threaded hole in the middle of the nut, and the ends of the two threaded rods are respectively fixedly connected to the side of the corresponding side beam.

[0012] Preferably, a No. 2 rotating seat is rotatably installed on both sides of the top beam, a No. 1 rotating seat is rotatably installed on both side beams, and one end of the No. 3 sleeve is fixedly connected to the No. 2 rotating seat, and one end of the No. 3 sliding rod is fixedly connected to the No. 1 rotating seat.

[0013] Preferably, the ends of the second sliding rod located inside the second sleeve are all fixedly connected to the second limiting plate, and the bottom of the bearing plate is fixedly connected to the bottom plate with an inclined reinforcing rod.

[0014] Preferably, the third sleeve has a plurality of through holes evenly arranged along its setting direction on its side, and the third sliding rod has a strip groove through its side. A screw rod is installed through the through holes at the same height on the third sleeve on the same side, and the screw rod is installed through the strip groove on the side of the third sliding rod on the same side.

[0015] The advantages of this utility model are:

[0016] 1. This utility model describes a mechanism where, when a photovoltaic panel is subjected to strong winds, the photovoltaic panels on the two mounting plates will flip downwards around the rotating connecting shaft of the first rotating seat on each side due to the wind force. After the top beam is compressed, it will squeeze the spring downwards through the first sliding rod and the first limiting plate. When the third sleeve follows the top beam and its height decreases, the windward force-bearing area of ​​the photovoltaic panel on the mounting plate will decrease, thereby reducing the amount of wind force the photovoltaic panel can withstand. When the wind force decreases, the top beam will be lifted upwards again under the pushing force of the spring, and the extension length of the third sleeve and the third sliding rod will return to its original state, thus restoring the tilt angle of the photovoltaic panel on the mounting plate, so as to achieve an adaptive adjustment function.

[0017] 2. This utility model forms a triangular support frame by connecting the No. 1 sliding rod, the No. 4 sleeve, the lead screw, the No. 3 sleeve, and the No. 3 sliding rod on both sides of the top beam. When the lengths of the two sides of the No. 4 sleeve, the lead screw, the No. 3 sleeve, and the No. 3 sliding rod in the triangular frame are fixed, the lifting height of the top beam will also be limited. Moreover, the tilt angle of the mounting plate in the triangular frame is different under different side length states, which can be applied to photovoltaic panels with different fixed angle requirements and improve the applicability of the bracket.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0027] Please see Figure 1-6 As shown, the photovoltaic panel wind-resistant support includes a bearing plate 1, on which multiple first sleeves 2 arranged horizontally are fixedly connected. A first annular baffle 3 is fixedly connected to the top end of each of the first sleeves 2. A first sliding rod 4 is slidably installed through the hole in the middle of each of the first annular baffles 3. A top beam 5 is fixedly connected to the top of the multiple first sliding rods 4.

[0028] Two second sleeves 6 are fixedly connected to both sides of the bearing plate 1. A second annular baffle 7 is fixedly connected to the end of each second sleeve 6. A second sliding rod 8 is slidably arranged inside each second annular baffle 7. A side beam 9 is fixedly connected between the ends of the second sliding rods 8 located on the same side.

[0029] Multiple No. 3 sleeves 12 are rotatably connected to both sides of the top beam 5. A No. 3 sliding rod 13 is slidably arranged in the port of each of the multiple No. 3 sleeves 12. The ends of the No. 3 sliding rods 13 located on the same side are rotatably connected to the side beam 9 on the corresponding side. The upper part of the No. 3 sleeves 12 located on the same side is fixedly connected to the mounting plate 14.

[0030] The end of the first sliding rod 4 located inside the first sleeve 2 is fixedly connected to a first limiting plate 15, and a spring 16 is provided inside the first sleeve 2 and below the first limiting plate 15.

[0031] The top beam 5 is rotatably mounted with a second rotating seat 11 on both sides, and the two side beams 9 are rotatably mounted with a first rotating seat 10. The bottom ends of the multiple first sleeves 2 are fixedly connected to a base plate 25, and the spring 16 is located on the upper part of the base plate 25.

[0032] The bearing plate 1 is provided with a No. 2 sleeve 6 and a No. 4 sleeve 20 is fixedly connected to both sides. A nut 21 is rotatably installed at the port of the No. 4 sleeve 20. A screw 22 is threadedly connected to the screw nut 21 through the threaded hole in the middle. The ends of the two screws 22 are respectively fixed to the side of the side beam 9 on the corresponding side.

[0033] The top beam 5 is rotatably mounted with a second rotating seat 11 on both sides, and a first rotating seat 10 is rotatably mounted on each of the two side beams 9. One end of the third sleeve 12 is fixed to the second rotating seat 11, and one end of the third sliding rod 13 is fixed to the first rotating seat 10.

[0034] The ends of the second sliding rod 8 located inside the second sleeve 6 are all fixedly connected to the second limiting plate 24, and the bottom of the bearing plate 1 is fixedly connected to the bottom plate 25 with an inclined reinforcing rod 23.

[0035] The third sleeve 12 has a plurality of uniformly arranged through holes 17 on its side along its setting direction. The third sliding rod 13 has a strip groove 18 through its side. The third sleeve 12 on the same side has a screw 19 through the through holes 17 at the same height. The screw 19 also passes through the strip groove 18 on the side of the third sliding rod 13 on the same side.

[0036] During operation, existing photovoltaic panel wind-resistant supports require manual control of the electric push rod extension and retraction via an adjustment switch to adjust the photovoltaic panel's angle of attack, making it impossible to adaptively adjust to wind force, resulting in inconvenience and low ease of operation. In this solution, in the initial state, spring 16 will always push the first limiting plate 15 upward, causing the first limiting plate 15 to slide upward within the first sleeve 2, and the top beam 5 will be lifted upward by multiple first sliding rods 4, so that the third sleeve 12 and the third sliding rod 13 located on both sides of the top beam 5 will rotate around the rotation connection axis of the first rotating seat 10 on both sides, thereby adjusting the rotation angle of the mounting plates 14 on both sides. When the top beam 5 moves upward, it will drive the third sleeve 12 on both sides to slide outside the multiple third sliding rods 13, thereby adjusting the connection length between the third sleeve 12 and the third sliding rod 13. Under the limitation of the screw 19 by the strip groove 18, when the third sleeve 12 slides to a certain distance, it will be restricted by the screw 19 and the strip groove 18.

[0037] In use, the photovoltaic panel is installed on the mounting plate 14, and the tilt angle of the two mounting plates 14 is adjusted according to the actual installation environment of the photovoltaic panel. During adjustment, the nuts 21 on both sides are rotated. Under the action of the threaded connection between the nuts 21 and the lead screw 22, the lead screw 22 is extended and retracted within the fourth sleeve 20. When the lead screw 22 is extended and retracted, it will drive the two second sliding rods 8 on the same side to slide and retract within the corresponding second sleeves 6 through the side beam 9 fixed to it. By adjusting the insertion position of the screw 19, the screws 19 on both sides are inserted into the through holes 17 at the same height to adjust the third sleeve. Adjusting the sliding distance of sleeve 12 and the extension length of sliding rod 13 allows a triangular support frame to be formed between sliding rod 4, sleeve 20, screw 22, sleeve 12, and sliding rod 13 on both sides of the top beam 5. When the lengths of sleeve 20, screw 22, sleeve 12, and sliding rod 13 in the triangular frame are fixed, the lifting height of the top beam 5 will be limited. The tilt angle of mounting plate 14 in the triangular frame is also different under different side lengths, which can be applied to photovoltaic panels with different fixed angle requirements and improve the applicability of the bracket.

[0038] When the photovoltaic panels are subjected to strong winds, the panels on the two mounting plates 14 will flip downwards around the rotating connecting shafts of the first rotating seats 10 on both sides due to the wind force. Since the mounting plates 14 are mounted on the third sleeve 12, the flipping force on the mounting plates 14 is transmitted to the top beam 5, causing it to be subjected to downward pressure. Under this pressure, the top beam 5 will compress the spring 16 downwards via the first sliding rod 4 and the first limiting plate 15, causing it to contract. When the first sliding rod 4 contracts into the first sleeve 2, the third sleeves 12 and the third sliding rod 13 on both sides will rotate around the rotating connecting shafts of the first rotating seats 10 on both sides. During rotation, the third sliding rod 13 slides and retracts within the third sleeve 12 to ensure that the first sliding rod 4 can accurately descend and retract into the first sleeve 2. When the third sleeve 12 follows the top beam 5 and rotates and descends, the windward force-bearing area of ​​the photovoltaic panel on the mounting plate 14 will decrease, thereby reducing the wind force that the photovoltaic panel can withstand and improving its wind resistance. When the wind force decreases, the top beam 5 will be lifted upward again under the thrust of the spring 16, and the extension length of the third sleeve 12 and the third sliding rod 13 will return to its original state, thereby restoring the tilt angle of the photovoltaic panel on the mounting plate 14 to achieve adaptive adjustment.

[0039] The system achieves the wind resistance and adaptive adjustment of photovoltaic panels, making it more convenient to use than traditional photovoltaic panel mounting brackets. It responds quickly to sudden strong winds, requiring no extra manual operation and improving the stability of photovoltaic panels.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
