Technical Field
[0001] This utility model relates to the field of photovoltaic bracket angle adjustment, specifically a photovoltaic bracket docking structure that can be adapted to multi-angle connections. Background Technology
[0002] With the rapid development of photovoltaic power generation systems, photovoltaic brackets, as important structures for supporting and fixing photovoltaic modules, directly affect the installation efficiency and service life of photovoltaic panels due to their stability and adaptability. A photovoltaic bracket mainly consists of base plates, columns, triangular plates, tie rods, and crossbeams. The base plates are bolted to the bottom of the columns, and the triangular plates are installed at the top of the columns. A connecting sleeve runs through the column and the triangular plates, connecting them. The tie rods are bolted to the top of the triangular plates, and the crossbeams are bolted to intersect with the tie rods. Photovoltaic modules are installed at the top of the crossbeams via various components. The connecting structure of the photovoltaic bracket is generally installed between the triangular plates and the columns. Depending on the requirements, the connecting structure adjusts the angle of the photovoltaic modules to meet the optimal angle adjustment needs of the photovoltaic panels, thereby improving the utilization rate of solar energy.
[0003] However, in the existing technology, adjusting the angle of photovoltaic modules requires manually pulling out the positioning pins or loosening the bolts to adjust the angle of the triangular plate. The adjustment steps are cumbersome and time-consuming. Construction workers may encounter difficulties in operation when working at heights, which poses certain safety hazards. Utility Model Content
[0004] The purpose of this invention is to provide a photovoltaic support docking structure that can be adapted to multi-angle connections, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: it includes a docking sleeve, which is installed between a triangular plate and a column. Multiple sets of positioning holes are formed on the surface of the docking sleeve. The outer ring of the docking sleeve is driven to rotate by a transmission structure. A positioning rod is inserted into the positioning hole. A dome is fixed at the top of the positioning rod. The transmission structure drives the adjustment structure to rotate. The adjustment structure drives the positioning rod to reciprocate.
[0006] Preferably, the multiple sets of positioning holes are arranged in a circumferential array around the central axis of the sleeve, with the positioning holes located in the middle of the column.
[0007] Preferably, the transmission structure includes a rotating shaft, a first gear, and a second gear. The rotating shaft passes through the side wall of the column, and a gear is fitted onto one end of the rotating shaft. The outer sides of the first gear and the outer sides of the second gear are meshed and connected. The second gear is fitted onto the outer side of the mating sleeve.
[0008] Preferably, the inner ring of the second gear has a movable groove with an arc-shaped structure, and the outer ring of the mating sleeve is fixed with a limiting arc block. The limiting arc block is located inside the movable groove, and the arc length of the limiting arc block is less than the arc length of the movable groove.
[0009] Preferably, the positioning rod is located directly above the docking sleeve.
[0010] Preferably, the adjustment structure includes a connecting rod, an adjusting disc, and an adjusting slope. One end of the connecting rod is fixed to the side surface of the gear, and the adjusting disc is fixed to the other end of the connecting rod. Both the adjusting disc and the connecting rod are located on the outer ring of the mating sleeve. The adjusting slope is fixed on the inner ring of the adjusting disc. The adjusting disc and the adjusting slope are integrally formed. The protruding arc slope of the adjusting slope corresponds one-to-one with the positioning hole. The concave slope of the adjusting slope is in the shape of a slope curve, and the dome slides on the outer surface of the adjusting slope.
[0011] Preferably, a limiting plate is fixed to the outer surface of the positioning rod, a return spring is fixed to the bottom surface of the limiting plate, a fixing plate is fixed to the other end of the return spring, the fixing plate is fixed to the inner wall of the column, and the positioning rod passes through the fixing plate.
[0012] Preferably, the column is divided into two layers. The upper column slides inside the outer shell, and the lower column is fixed to the lower surface of the outer shell. A support plate is fixed to the bottom of the upper column. The support plate is connected to the inner bottom surface of the outer shell by two sets of connecting rods.

The outer shell surface is provided with a plug hole, and a plug rod is inserted into the plug hole. The plug rod passes through the support plate.
[0013] Compared with the prior art, the beneficial effects of this utility model are: The photovoltaic bracket docking structure proposed in this utility model can be adapted to multiple angles. When it is necessary to adjust the angle of the collar, that is, to adjust the angle of the photovoltaic module, only a rotating shaft on the column at the same height is needed. At this time, the rotating shaft drives the gears to mesh and transmit power. Then, the connecting rod drives the adjustment plate to rotate. At the same time, the dome at the top of the internal positioning rod slides along the adjustment slope. Under the action of the return spring, the dome at the top of the positioning rod is always in contact with the adjustment slope. When it rotates to the convex slope of the adjustment slope, the positioning rod will be inserted into the positioning hole, thereby driving the triangular plate to adjust the angle, and finally driving the photovoltaic module to adjust the angle.

[0016] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0017] Example 1 Please see Figures 1-9This utility model provides a technical solution: a photovoltaic bracket docking structure adaptable to multi-angle connections, including a docking sleeve 2, which is installed between a triangular plate 1 and a column 3. The surface of the docking sleeve 2 is provided with multiple sets of positioning holes 4, which are arranged in a circumferential array around the central axis of the docking sleeve 2. The positioning holes 4 are located in the middle of the column 3. The outer ring of the docking sleeve 2 is driven to rotate by a transmission structure, which includes a rotating shaft 5, a first gear 6, and a second gear 7. The rotating shaft 5 passes through the side wall of the column 3. The first gear 6 is sleeved on one end of the rotating shaft 5. The outer side of the first gear 6 and the outer side of the second gear 7 are meshed and connected. The second gear 7 is sleeved on the outer side of the docking sleeve 2. The inner ring of the second gear 7 is provided with a moving groove 16, which has an arc-shaped structure. The outer ring of the docking sleeve 2 is fixed with a limiting arc block 17, which is located inside the moving groove 16 and the arc length of the limiting arc block 17 is less than the arc length of the moving groove 16. Specifically, the photovoltaic support system mainly consists of foot plates, columns 3, triangular plates 1, tie rods, and crossbeams. The foot plates are bolted to the bottom of the columns 3, and triangular plates 1 are installed on the top of the columns 3. A connecting sleeve 2 passes through the columns 3 and triangular plates 1 to connect them. The tie rods are bolted to the top of the triangular plates 1. The crossbeams are bolted to the tie rods, and photovoltaic modules are installed on the top of the crossbeams via some components.
[0018] The servo motor drives gear 6 to rotate by rotating shaft 5. Since gear 6 and gear 7 mesh, gear 7 rotates, which in turn drives the docking sleeve 2 to rotate. The docking sleeve 2 has keyways and keys at both ends with the triangle plate 1, which causes the triangle plate 1 to rotate as well. This adjusts the collar at the top of the triangle plate 12, which in turn adjusts the angle of the photovoltaic module. When the docking sleeve 2 rotates, the limiting arc block 17 slides along an arc trajectory in the moving groove 16. Only when the limiting arc block 17 moves to the other end of the moving groove 16 will it drive the docking sleeve 2 to rotate synchronously. Since the moving groove 16 provides gear 7 with a certain number of rotations, gear 7 will drive the connecting plate 9 to rotate, causing the positioning rod 11 to first disengage from the positioning hole 4, automatically exit the current positioning hole 4 and move with the rotation. When the docking sleeve 2 rotates to a new angle, the positioning hole 4 and the limiting structure are realigned and automatically engaged, thus completing the multi-angle adjustment and locking of the triangle plate 1 and the column 3.
[0019] Example 2 Based on Embodiment 1, in order to achieve angle adjustment of the photovoltaic module, a positioning rod 11 is inserted into the positioning hole 4. The positioning rod 11 is located directly above the docking sleeve 2. A dome 15 is fixed at the top of the positioning rod 11. The transmission structure drives the adjustment structure to rotate, and the adjustment structure drives the positioning rod 11 to reciprocate. The adjustment structure includes a connecting rod 8, an adjusting disc 9, and an adjusting slope 10. One end of the connecting rod 8 is fixed to the side surface of the gear 6, and the adjusting disc 9 is fixed to the other end of the connecting rod 8. Both the adjusting disc 9 and the connecting rod 8 are located on the outer ring of the docking sleeve 2. The adjusting slope 10 is fixed on the inner ring of the adjusting disc 9. The adjusting disc 9 and the adjusting slope 10 are integrally formed. The protruding arc slope of the adjusting slope 10 corresponds one-to-one with the positioning hole 4. The concave slope of the adjusting slope 10 is in the shape of a slope curve. The dome 15 slides on the outer surface of the adjusting slope 10. The outer surface of the positioning rod 11 is fixed. A limiting plate 12 is fixed, and a return spring 13 is fixed to the bottom surface of the limiting plate 12. A fixing plate 14 is fixed to the other end of the return spring 13. The fixing plate 14 is fixed to the inner wall of the column 3. The positioning rod 11 passes through the fixing plate 14. The column 3 is divided into two layers. The upper column 3 slides inside the outer shell 18, and the lower column 3 is fixed to the lower surface of the outer shell 18. A support plate 20 is fixed to the bottom end of the upper column 3. The support plate 20 is connected to the inner bottom surface of the outer shell 18 by two sets of connecting rods 19. The two sets of connecting rods 19 cross each other and rotate relative to each other. Both ends of the two sets of connecting rods 19 slide in the sliding groove through the sliding seat. The upper sliding groove is opened on the bottom surface of the support plate 20, and the lower sliding groove is opened on the inner bottom surface of the outer shell 18. An insertion hole 21 is opened on the surface of the outer shell 18. An insertion rod 22 is inserted into the insertion hole 21 and passes through the support plate 20. Specifically, the operator drives the transmission structure to rotate via a servo motor. The transmission structure drives the connecting rod 8 to rotate, and the adjusting plate 9 connected to the other end of the connecting rod 8 rotates accordingly. Then, the dome 15 at the top of the positioning rod 11 remains in contact with the surface of the adjusting slope 10 under the action of the return spring 13 and slides up and down accordingly. When the dome 15 slides to the concave slope position of the adjusting slope 10, the positioning rod 11 pops out from the positioning hole 4 under the action of the return spring 13. The adjusting plate 9 continues to rotate, driving the triangular plate 1 to achieve angle adjustment. When the dome 15 slides to the convex slope of the adjusting slope 10, the positioning rod 11 is inserted into the positioning hole 4, thereby locking the docking sleeve 2.
[0020] To reiterate, when the photovoltaic module at the front end is adjusted via the transmission mechanism, the rear column 3 also needs to be raised to allow the photovoltaic module to adjust its angle. Otherwise, it cannot be adjusted. Simply remove the insert rod 22 from the socket 21. When adjusting the front column 3, the angle of the photovoltaic module is adjusted by adjusting the triangular plate 1 via the transmission structure. Due to the change in angle, the triangular plate 1 at the rear will force the rear column 3 to rise. The two sets of connecting rods 19 inside the outer casing 18 form a scissor shape, thereby raising the upper column 3. After it rises to the specified height, the insert rod 22 is inserted into the socket 21 to fix it. When the two sets of connecting rods 19 push the support plate 20 to rise, the slides at both ends of the two sets of connecting rods 19 slide along the slide groove.
[0021] In use, the operator starts the servo motor to drive the transmission structure to rotate. The transmission structure drives the connecting rod 8 to rotate synchronously. The adjusting plate 9 fixed at the other end of the connecting rod 8 rotates accordingly. The dome 15 at the top of the positioning rod 11 is always in close contact with the surface of the adjusting slope 10 under the elastic force of the return spring 13 and slides up and down accordingly. When the dome 15 moves to the concave slope position of the adjusting slope 10, the positioning rod 11 disengages from the positioning hole 4 under the elastic force. The adjusting plate 9 continues to rotate, driving the triangular plate 1 to achieve angle adjustment. When the dome 15 slides to the convex slope of the adjusting slope 10, the positioning rod 11 re-inserts into the positioning hole 4 under the elastic force, thereby completing the locking of the docking sleeve 2.
[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
