Description

Technical Field

[0001] This utility model relates to the field of photovoltaic bracket angle adjustment technology, and in particular to a photovoltaic bracket. Background Technology

[0002] Photovoltaic power generation, as an important form of clean and renewable energy, occupies a key position in the global energy structure transformation. As the core structure supporting photovoltaic panels, the performance of photovoltaic support structures directly affects the efficiency of photovoltaic panels in receiving solar energy, and thus determines the overall power generation efficiency of photovoltaic power plants.

[0003] Existing adjustable-angle photovoltaic (PV) brackets, such as the Chinese invention patent application with publication number CN118399864A, disclose an adjustable-angle PV bracket. This bracket includes a column, a mounting frame, and a first connector. The first connector is rotatably connected to the column, and the mounting frame is connected to the first connector to mount the PV panel. The rotation of the first connector relative to the column drives the rotation of the mounting frame and the PV panel. Simultaneously, the bracket also includes a first diagonal brace and a second diagonal brace. One end of the diagonal brace is slidably connected to the mounting frame, and the other end is rotatably connected to both sides of the column. Adjustment is achieved by manually rotating the mounting frame, causing the diagonal brace to slide along a slide rail on the mounting frame to adapt to angle changes. Finally, the first and second limiting members restrict the sliding of the diagonal brace, thus fixing the angle.

[0004] Although the solution achieves adjustable photovoltaic panel angle and improves solar energy reception to some extent, its first and second diagonal supports are fixed-length structures. When adjusting the photovoltaic angle, the limiting device must be loosened first, then the photovoltaic panel must be moved to the appropriate angle and manually held, and then a second person must fix the limiting device to fix the angle. This means that the adjustment process requires two people to operate, which increases the workload and reduces work efficiency. Utility Model Content

[0005] To address the problem that the current first and second diagonal braces are fixed-length structures, requiring two people to operate when adjusting the photovoltaic angle, which increases labor and reduces work efficiency, this utility model provides a photovoltaic bracket.

[0006] To solve the above problems, the technical solution adopted by this utility model is as follows: A photovoltaic (PV) support system includes a column and a mounting frame. The top of the column is hinged to the middle of the mounting frame via a first connector. A second connector is mounted in the middle of the column. A length adjustment component is hinged to the bottom surface of one end of the mounting frame; the end of the length adjustment component away from the mounting frame is hinged to the second connector. A telescopic component is hinged to the bottom surface of the other end of the mounting frame; the end of the telescopic component away from the mounting frame is hinged to the second connector. The first connector at the top of the column forms a stable rotation fulcrum by hinged to the middle of the mounting frame. The second connector in the middle of the column provides a fixed hinged base for the length adjustment and telescopic components at both ends of the mounting frame. When adjusting the angle of the PV panel, the support height at one end of the mounting frame can be actively changed by operating the length adjustment component alone. Simultaneously, the telescopic component can adapt to the positional change at the other end of the mounting frame to assist in angle adjustment. The entire adjustment process requires only one person to complete the adjustment of the length adjustment component, the adaptation of the telescopic component, and subsequent locking operations, significantly reducing the workload of angle adjustment, significantly improving the adjustment efficiency of a single support system, effectively reducing overall operation and maintenance costs, and improving operation and maintenance efficiency.

[0007] Preferably, the length adjustment component and the telescopic component are hinged to both ends of the mounting frame via two third connectors; each third connector includes a fixed plate; side plates are vertically fixed to both ends of the fixed plate; hinge holes for connecting the length adjustment component or the telescopic component are provided on the side plates; a fourth pin is fixedly provided on the top surface of the fixed plate; the fourth pin has external threads and engages with a connecting nut to connect to the mounting frame. The top surface of the fixed plate is connected to the mounting frame via the fourth pin and the connecting nut, which enables the hinged connection between the third connector and the mounting frame, and at the same time, the connecting nut ensures the stability of the connection between the third connector and the mounting frame.

[0008] Preferably, the length adjustment assembly includes an internally threaded tube closed at one end and open at the other; a screw is threaded onto the internal thread of the internally threaded tube; a fixing nut is threaded onto the screw; the internally threaded tube is hinged to a second connector via a connecting unit; and a side plate is hinged to the end of the screw away from the internally threaded tube. The threaded fit design of the internally threaded tube and the screw allows for adjustment of their fit length by actively rotating either the internally threaded tube or the screw, thereby precisely changing the overall support height of the length adjustment assembly. This drives the mounting frame to rotate stably around the first connector, achieving adjustment of the photovoltaic panel angle without manually manipulating the mounting frame and maintaining the angle. Simultaneously, the fixing nut on the screw can be quickly tightened after the length adjustment is complete, directly locking the relative position of the internally threaded tube and the screw, ensuring the length adjustment assembly is firmly supported and preventing angle deviation. Furthermore, a single person can independently adjust and lock the photovoltaic panel angle, effectively solving the problems of high labor intensity and low efficiency in adjustment. The threaded fit adjustment method offers higher precision, more accurately matching the changing solar incidence angle requirements of different seasons, further ensuring the photovoltaic panel's solar energy reception efficiency.

[0009] Preferably, a hexagonal groove is provided on the outer wall of the internally threaded tube. This provides a stable force point for the operator to rotate the internally threaded tube.

[0010] Preferably, the connecting unit includes a fourth connecting member and a circular groove fixedly disposed at the closed end of the internally threaded pipe; the fourth connecting member includes a connecting disc that can be fitted into the circular groove; a connecting rod is coaxially fixedly disposed on the connecting disc; a hinge block for hinged to the second connecting member is fixedly disposed at the end of the connecting rod away from the connecting disc; two semi-circular ring washers are installed at the closed end of the internally threaded pipe in conjunction with the connecting rod. The circular groove at the closed end of the internally threaded pipe and the connecting disc of the fourth connecting member form a fit, which can provide a stable positioning reference for the connection between the length adjustment component and the second connecting member, avoiding uneven force due to offset during adjustment. At the same time, the two semi-circular ring washers can effectively limit the connecting disc from disengaging from the circular groove along the connecting rod axially without interfering with the rotation of the connecting disc.

[0011] Preferably, a first boss is fixedly provided at the end of the screw away from the internal threaded tube; a first through hole is provided on the first boss; a first pin is inserted through the first through hole and the hinge hole. The first through hole and the hinge hole on the side plate of the third connector are engaged by the first pin to form a rigid and highly adaptable hinge structure, which can not only meet the motion requirements of the length adjustment component to drive the mounting bracket to rotate when the length is actively changed, but also avoid the jamming and loosening problems caused by wear of the rotating shaft and the diagonal brace connection in the comparison document.

[0012] Preferably, the telescopic assembly includes a sleeve; the bottom surface of the sleeve is hinged to a third connector via a second pin; a sliding rod is slidably disposed inside the sleeve; the end of the sliding rod away from the sleeve is hinged to a second connector. The sliding rod slidably disposed inside the sleeve can extend and retract synchronously with the rotation of the mounting frame around the first connector, automatically adapting to the height difference between the two ends of the mounting frame when the length adjustment assembly is adjusted, eliminating the need to manually move the mounting frame to drive the diagonal brace to slide along the slide rail, and eliminating the need for additional personnel to continuously maintain the angle of the mounting frame.

[0013] Preferably, a second boss is fixedly provided on the bottom surface of the sleeve; the second boss is hinged to the hinge hole through a second pin.

[0014] Preferably, a second through hole is provided at the end of the slide rod away from the sleeve; a third pin for hinged connection of the second connector is inserted through the second through hole. The second boss on the bottom surface of the sleeve is hinged to the hinge hole through the second pin, which can provide a precise positioning reference for the connection between the sleeve and the third connector, avoiding the gap or offset problems that are easily caused by the sliding connection of the diagonal brace and the connector relying solely on the sliding groove in the prior art, and ensuring the stable transmission of force between the telescopic component and the mounting frame; the second through hole at the end of the slide rod away from the sleeve, in conjunction with the third pin, hinges the second connector, which can realize the smooth rotation of the slide rod and the second connector, so that the slide rod can synchronously and stably extend and retract with the angle adjustment of the mounting frame.

[0015] Preferably, the sleeve has an elongated through hole at its open end, and an external thread is provided on the outer wall of the sleeve's open end; a locking nut is threaded onto the external thread. The elongated through hole at the sleeve's open end, along with the external thread and the locking nut, allows the slide rod to quickly lock in its position after it has extended or retracted to its designated position. This enables more precise adjustment of the telescopic component and more convenient locking, allowing for operation by a single person and eliminating the need for two people to work together.

[0016] As can be seen from the above technical solution, the advantages of this utility model include: a stable rotation fulcrum is formed by hinged mounting bracket at the top of the column; the second connector at the middle of the column provides a fixed hinged base for the length adjustment components and telescopic components at both ends of the mounting bracket; when adjusting the angle of the photovoltaic panel, the support height of one end of the mounting bracket can be actively changed by operating the length adjustment component alone; at the same time, the telescopic component can adapt to the position change of the other end of the mounting bracket to assist in angle adjustment; the entire adjustment process can be completed by a single person to adjust the length adjustment component, adapt the telescopic component, and perform subsequent locking operations, which greatly reduces the workload of angle adjustment, significantly improves the adjustment efficiency of a single bracket, effectively reduces the overall operation and maintenance cost, and improves the efficiency of operation and maintenance work.

Detailed Implementation

[0024] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0025] like Figure 1 , Figure 2 and Figure 3 As shown, a photovoltaic bracket includes a column 1 and a mounting frame 3. The top of the column 1 is hinged to the middle of the mounting frame 3 via a first connector 2. A second connector 4 is installed in the middle of the column 1. A length adjustment component is hinged to the bottom surface of one end of the mounting frame 3. The end of the length adjustment component away from the mounting frame 3 is hinged to the second connector 4. A telescopic component is hinged to the bottom surface of the other end of the mounting frame 3. The end of the telescopic component away from the mounting frame 3 is hinged to the second connector 4. The length adjustment component and the telescopic component are respectively hinged to both ends of the mounting frame 3 via two third connectors 5. The third connector 5 includes a fixing plate 501. Side plates 502 are vertically fixed to both ends of the fixing plate 501. The side plates 502 are provided with hinge holes 503 for connecting the length adjustment component or the telescopic component. A fourth pin 504 is fixedly provided on the top surface of the fixing plate 501. The fourth pin 504 is provided with external threads and cooperates with a connecting nut 505 to connect with the mounting frame 3.

[0026] A stable rotation fulcrum is formed by hinged mounting bracket 3 at the top of column 1 via the first connector 2. The second connector 4 at the middle of column 1 provides a fixed hinged base for the length adjustment components and telescopic components at both ends of mounting bracket 3. When adjusting the angle of the photovoltaic panel, the support height of one end of mounting bracket 3 can be actively changed by operating the length adjustment component alone. At the same time, the telescopic component can adapt to the position change of the other end of mounting bracket 3 to assist in angle adjustment. The entire adjustment process can be completed by a single person, including adjusting the length adjustment component, adapting the telescopic component, and subsequent locking operations. This significantly reduces the workload of angle adjustment, significantly improves the adjustment efficiency of a single bracket, effectively reduces overall operation and maintenance costs, and improves operation and maintenance efficiency. The top surface of the fixing plate 501 is connected to the mounting bracket 3 via the fourth pin 504 and the connecting nut 505, which enables the hinged connection between the third connector 5 and the mounting bracket 3. At the same time, the connecting nut 505 can ensure the stability of the connection between the third connector 5 and the mounting bracket 3.

[0027] like Figure 1 and Figure 4 As shown, the telescopic assembly includes a sleeve 11; the bottom surface of the sleeve 11 is hinged to a third connecting member 5 via a second pin 12; a sliding rod 13 is slidably disposed inside the sleeve 11; the end of the sliding rod 13 away from the sleeve 11 is hinged to a second connecting member 4. A second boss 1101 is fixedly disposed on the bottom surface of the sleeve 11; the second boss 1101 is hinged to a hinge hole 503 via a second pin 12. A second through hole 1301 is opened at the end of the sliding rod 13 away from the sleeve 11; a third pin 14 for hinged to the second connecting member 4 passes through the second through hole 1301. An elongated through hole 1102 is opened at the open end of the sleeve 11, and an external thread is provided on the outer wall of the open end of the sleeve 11; a locking nut 15 is threaded on the external thread.

[0028] The sliding rod 13, which is slidably installed inside the sleeve 11, can extend and retract synchronously with the rotation of the mounting frame 3 around the first connecting member 2. It automatically adapts to the height difference between the two ends of the mounting frame 3 when the length adjustment component is adjusted, eliminating the need to manually move the mounting frame 3 to drive the diagonal brace to slide along the slide rail, and eliminating the need for additional personnel to continuously maintain the angle of the mounting frame 3. The second boss 1101 on the bottom surface of the sleeve 11 is hinged to the hinge hole 503 through the second pin 12, which can provide a precise positioning reference for the connection between the sleeve 11 and the third connecting member 5. This avoids the gap or offset problems that are easily caused by the diagonal brace and the connecting member relying solely on the sliding groove connection in the prior art, and ensures the stable transmission of force between the telescopic component and the mounting frame 3. The second through hole 1301 at the end of the sliding rod 13 away from the sleeve 11 is hinged to the second connecting member 4 with the third pin 14, which can realize the smooth rotation of the sliding rod 13 and the second connecting member 4, so that the sliding rod 13 can extend and retract synchronously and stably with the angle adjustment of the mounting frame 3. The elongated through hole 1102 at the open end of the sleeve 11, along with the external thread engaging with the locking nut 15, allows the slide rod 13 to be quickly locked in position after it has been extended or retracted. This enables more precise adjustment and easier locking of the telescopic component, allowing for operation by a single person and eliminating the need for two people to work together.

[0029] In other alternative embodiments, the telescopic component is replaced with a gas spring, which is more expensive.

[0030] like Figure 1 and Figure 5 As shown, the length adjustment assembly includes an internally threaded tube 6 that is closed at one end and open at the other; a screw 7 is threaded onto the internal thread of the internally threaded tube 6; a fixing nut 8 is threaded onto the screw 7; the internally threaded tube 6 is hinged to a second connecting member 4 via a connecting unit; a side plate 502 is hinged to the end of the screw 7 away from the internally threaded tube 6. A hexagonal groove 601 is provided on the outer wall of the internally threaded tube 6, which can provide a stable force point for the operator to rotate the internally threaded tube 6. The connecting unit includes a fourth connecting member 9 and a circular groove 602 fixedly disposed at the closed end of the internally threaded tube 6; the fourth connecting member 9 includes a connecting plate 901 that can be fitted into the circular groove 602; a connecting rod 902 is coaxially fixedly disposed on the connecting plate 901; a hinge block 903 for hinged to the second connecting member 4 is fixedly disposed at the end of the connecting rod 902 away from the connecting plate 901; two semi-circular ring washers 904 are installed at the closed end of the internally threaded tube 6 in conjunction with the connecting rod 902. A first boss 701 is fixedly provided at the end of the screw 7 away from the internal threaded tube 6; a first through hole 702 is provided on the first boss 701; a first pin 10 is inserted into the first through hole 702 and the hinge hole 503.

[0031] The threaded fit design of the internally threaded tube 6 and the screw 7 allows for adjustment of their mating length by actively rotating either the internally threaded tube 6 or the screw 7, thereby precisely changing the overall support height of the length adjustment component. This drives the mounting frame 3 to rotate stably around the first connector 2, achieving photovoltaic panel angle adjustment without the need for manual manipulation of the mounting frame 3 and continuous angle maintenance. Simultaneously, the fixing nut 8 on the screw 7 can be quickly tightened after the length adjustment is complete, directly locking the relative position of the internally threaded tube 6 and the screw 7, ensuring the length adjustment component is firmly supported and preventing angle deviation. Furthermore, a single person can independently adjust and lock the photovoltaic panel angle, effectively solving the problems of high labor intensity and low efficiency in adjustment. The threaded fit adjustment method offers higher precision, more accurately matching the changing solar incidence angle requirements of different seasons, further ensuring the photovoltaic panel's solar energy reception efficiency. The circular groove 602 at the closed end of the internally threaded tube 6 mates with the connecting disc 901 of the fourth connector 9, providing a stable positioning reference for the connection between the length adjustment component and the second connector 4, preventing uneven force distribution due to deviation during adjustment. Meanwhile, the two semi-circular ring washers 904 can effectively restrict the connecting plate 901 from detaching from the circular groove 602 along the connecting rod 902 without interfering with the rotation of the connecting plate 901. The first through hole 702 and the hinge hole 503 on the side plate 502 of the third connecting member 5 are fitted together by the first pin 10 to form a rigid and highly adaptable hinge structure. This structure can meet the motion requirements of the length adjustment component to drive the mounting bracket 3 to rotate when actively changing the length, and can also avoid the jamming and loosening problems caused by wear between the rotating shaft and the diagonal brace in the comparison document.

[0032] When adjusting the angle of the photovoltaic panels on this photovoltaic bracket, one person can complete the operation independently by following these steps: First, prepare for unlocking before adjustment—loosen the fixing nut 8 on the screw 7 in the length adjustment assembly to release the relative position lock between the internal thread tube 6 and the screw 7; at the same time, loosen the locking nut 15 at the opening end of the sleeve 11 in the telescopic assembly to release the sliding lock between the sleeve 11 and the slide rod 13, leaving room for angle adjustment.

[0033] Secondly, active angle adjustment is performed—the hexagonal groove 601 on the outer wall of the internally threaded tube 6 is clamped with a wrench, and the internally threaded tube 6 is rotated to adjust the thread engagement depth with the screw 7: if the tilt angle of the photovoltaic panel needs to be increased, the internally threaded tube 6 can be rotated forward to extend the screw 7 outward, causing the end of the mounting frame 3 hinged to the screw 7 to be raised upward; if the tilt angle of the photovoltaic panel needs to be decreased, the internally threaded tube 6 can be rotated in the opposite direction to retract the screw 7 inward, causing the corresponding end of the mounting frame 3 to be lowered downward. During this process, the mounting frame 3 will rotate stably around its hinge point with the first connecting piece 2 at the top of the column 1, while the telescopic component hinged to the other end of the mounting frame 3 will move synchronously—the slide rod 13 will automatically slide along the inner wall of the sleeve 11.

[0034] Finally, the angle is locked – after the photovoltaic panel rotates to the preset angle, first tighten the fixing nut 8 of the length adjustment component to lock the relative position of the internal threaded tube 6 and the screw 7, fixing the support height of one end of the mounting bracket 3; then tighten the locking nut 15 of the telescopic component to lock the relative position of the slide rod 13 and the sleeve 11, fixing the support state of the other end of the mounting bracket 3. At this point, the angle adjustment and locking operation of the photovoltaic bracket is complete, and the entire process requires no additional personnel.
