Description

Technical Field

[0001] This utility model relates to the field of photovoltaic solar panel installation technology, specifically a roof photovoltaic solar panel support with an anti-tipping structure. Background Technology

[0002] A photovoltaic solar panel is a power generation device that generates direct current when exposed to sunlight. It consists of thin solid photovoltaic cells made almost entirely of semiconductor materials. When photovoltaic solar panels are installed on a roof, the photovoltaic bracket is a key component for supporting and fixing the photovoltaic solar panels. Its performance directly affects the stability, safety and power generation efficiency of the entire photovoltaic system.

[0003] Most current mainstream rooftop photovoltaic (PV) brackets adopt a column-shaped structure design. While this can meet the basic installation requirements, it exposes significant shortcomings in complex natural environments. In rooftop installation scenarios, the brackets need to withstand continuous loads under extreme weather conditions such as strong winds and heavy rain. The wind pressure generated by strong winds acting on the surface of the PV panels will be transmitted to the roof connection points through the brackets. In areas with high wind speeds, this can easily cause the brackets to sway or even overturn, causing them to fall off the roof and posing a dual threat to the building structure and the safety of people. Therefore, we need to propose a rooftop PV solar bracket with an anti-tipping structure. Utility Model Content

[0004] The purpose of this invention is to provide a rooftop photovoltaic solar energy support system with an anti-tipping structure. By increasing the contact area with the roof through the mounting base, and then tightening the roof and mounting base with bolt holes, the stability of the support system after connection to the roof is further improved. By setting several sets of counterweights, the number of counterweights inside the support system can be increased according to the common strong wind levels in the installation area, further increasing the overall weight of the support system to enhance its stability. This solution avoids overall swaying or even overturning of the support system in high wind speed areas, preventing the support system from falling from the roof and posing a dual threat to the building structure and personnel safety, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a roof photovoltaic solar panel support with an anti-tipping structure, comprising a mounting base for installation on the roof, bolt holes being provided around the mounting base, a frame with anti-tipping function being provided at the top of the mounting base, an adjustment frame for adjusting the photovoltaic solar panels being provided at the top of the frame, the frame including a support base, load-bearing columns being welded and fixed on both sides of the top of the support base, a counterweight being provided between two sets of the load-bearing columns, and several sets of counterweights being provided, and a disassembly and assembly mechanism for easy disassembly and assembly from the mounting base being provided at the bottom of the support base.

[0014] This utility model provides a rooftop photovoltaic solar energy support system with an anti-tipping structure. By setting up the mounting base, the contact surface between the support and the roof is increased. Then, the roof and the mounting base are tightened through bolt holes, which further improves the stability of the support after the bottom of the support is connected to the roof.

[0021] 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 protection scope of the present utility model.

[0022] Please see Figures 1-4This utility model provides a technical solution: a roof photovoltaic solar panel support with an anti-tipping structure, including a mounting base 1 for installation on the roof, bolt holes 2 are provided around the mounting base 1, a frame with anti-tipping function is provided at the top of the mounting base 1, an adjustment frame 3 for adjusting the photovoltaic solar panel is provided at the top of the frame, the frame includes a support base 4, load-bearing columns 5 are welded and fixed on both sides of the top of the support base 4, a counterweight 6 is provided between the two sets of load-bearing columns 5, and several sets of counterweight 6 are provided, and a disassembly and assembly mechanism 7 is provided at the bottom of the support base 4 for easy disassembly and assembly from the mounting base 1;

[0023] First, the mounting base 1 is fixed to the roof through the bolt holes 2 around its perimeter, providing basic support for the overall structure. Then, the frame is connected to the mounting base 1 through the disassembly and assembly mechanism 7 at the bottom. The load-bearing column 5 on the support base 4 bears the weight of the top adjustment frame 3 and the photovoltaic solar panel. Next, according to the level of strong winds in the installation area, a corresponding number of counterweights 6 are added to lower the center of gravity of the frame by increasing its overall weight, thus achieving the anti-tipping function. At the same time, during installation, the installers can adjust the angle of the photovoltaic solar panel according to the sunlight requirements of the installation area. Through the above scheme, the overall swaying or even overturning of the support structure is avoided in high wind speed areas, and the support structure is prevented from falling from the roof, which would pose a double threat to the building structure and personnel safety.

[0024] The disassembly and assembly mechanism 7 includes a connecting groove 71 formed on the lower surface of the support base 4 and a connecting seat 72 adapted to the connecting groove 71. The connecting seat 72 is T-shaped and is welded and fixed to the upper surface of the mounting base 1. The top of the connecting seat 72 is also equipped with a positioning structure for positioning the support base 4. The frame and the mounting base 1 are quickly assembled by sliding docking. The positioning structure helps to fix the position of the support base 4 and avoids relative displacement after connection. The cooperation between the T-shaped connecting seat 72 and the connecting groove 71 simplifies the disassembly and assembly process. The docking or separation of the frame and the mounting base 1 can be completed without complicated tools, saving manpower and time.

[0025] The positioning structure includes a positioning hole 73 on the upper surface of the support base 4 and a limiting plate 74 for limiting the movement distance of the connecting base 72. The inner cavity of the positioning hole 73 is provided with a positioning pin 75 that matches the positioning hole 73. The limiting plate 74 is welded and fixed to the upper surface of the mounting base 1 and is located at the end away from the positioning hole 73. When the support base 4 and the connecting base 72 are aligned, one end of the support base 4 is in contact with the surface of the limiting plate 74. Then, the positioning pin 75 is inserted into the positioning hole 73 on the upper surface of the support base 4. The movement range of the support base 4 is limited by the positioning pin 75 and the limiting plate 74, which restricts the horizontal movement of the support base 4 and prevents relative sliding between the frame and the mounting base 1 due to wind vibration, thereby improving the reliability of the overall connection.

[0026] This embodiment also includes a positioning pin 75 with an external thread on its outer surface and a positioning hole 73 with an internal thread on its inner cavity. By connecting the positioning pin 75 with the positioning hole 73 by thread, the stability of the positioning pin 75 in the inner cavity of the positioning hole 73 can be further improved, and the positioning pin 75 can be prevented from moving out of the inner cavity of the positioning hole 73 due to external force.

[0027] The inner wall of the load-bearing column 5 is provided with a support groove 8. The inner cavity of the support groove 8 is provided with a support block 9 that is adapted to the support groove 8. The support block 9 is welded and fixed to the outer wall of the counterweight block 6. Through the cooperation of the support groove 8 and the support block 9, the counterweight block 6 is provided with vertical support force, so that the counterweight block 6 can be stacked along the support groove 8 without tilting outward. At the same time, the adaptation of the support block 9 and the support groove 8 ensures that the counterweight block 6 is installed stably, avoiding displacement or falling during the stacking process. It is convenient to flexibly adjust the number of counterweight blocks 6 according to the roof wind force, load-bearing and other requirements, and improve the adaptability of the anti-tipping structure.

[0028] It also includes a fixing structure 10 for fixing the position of the support block 9. The fixing structure 10 includes a movable hole 101 opened at the top of the load-bearing column 5, and the inner cavity of the movable hole 101 is connected to the inner cavity of several sets of support grooves 8. A fixing rod 102 is provided in the inner cavity of the movable hole 101. The surface of the support block 9 is provided with a fixing hole 103 that matches the fixing rod 102. When the counterweight 6 is stacked in place, the fixing rod 102 is inserted into the movable hole 101 at the top of the load-bearing column 5. The fixing rod 102 passes through the movable hole 101 and extends into the fixing hole 103 of the support block 9 in the support groove 8. The movement range of the support block 9 in the support groove 8 is limited by mechanical locking. The position of the counterweight 6 can be locked by the cooperation of the fixing rod 102 and the fixing hole 103, preventing the counterweight 6 from slipping due to vibration or tilting, thus enhancing the safety of the counterweight structure. The movable hole 101 is connected to multiple sets of support grooves 8, which can adapt to the fixing requirements of different numbers of counterweights 6 and increase flexibility.

[0029] The adjustment frame 3 includes an adjustment seat 31, which is bolted to the top of the load-bearing column 5. Adjustment plates 32 are integrally formed on both sides of the adjustment seat 31. The inner cavity of the adjustment plate 32 is rotatably connected to the mounting plate 33 for installing photovoltaic solar panels through bearings. The surface of the mounting plate 33 is provided with an adjustment structure for adjusting the position of the mounting plate 33. The adjustment frame 3 and the load-bearing column 5 can be disassembled through the bolt connection between the adjustment seat 31 and the load-bearing column 5. The mounting plate 33 is rotatably connected to the adjustment plates 32 on both sides of the adjustment seat 31 through bearings, and can rotate around the bearings to adjust the angle. After adjustment, the angle position of the mounting plate 33 is fixed by the adjustment structure to ensure that the photovoltaic solar panel is stably at the target angle.

[0030] The adjustment structure includes adjustment holes 34 formed on the surface of the adjustment plate 32, and several sets of adjustment holes 34 are provided. The several sets of adjustment holes 34 are distributed in an arc shape on the surface of the adjustment plate 32. The surface of the mounting plate 33 is provided with threaded holes 35 that are adapted to the adjustment holes 34. The threaded holes 35 and the adjustment holes 34 are fixed together by self-locking bolts. After the mounting plate 33 rotates around the bearing to the target angle, the threaded holes 35 on its surface are aligned with a certain set of adjustment holes 34 distributed in an arc on the surface of the adjustment plate 32. The self-locking bolts pass through the adjustment holes 34 and connect with the threaded holes 35. The locking force of the bolts is used to fix the position of the mounting plate 33, thereby realizing the adjustment of the angle of the mounting plate 33. The multiple sets of adjustment holes 34 distributed in an arc shape provide multiple angle adjustment options, which can make the photovoltaic solar panel adapt to the light conditions of different regions.

[0031] A reinforcing block 11 is welded and fixed to the bottom end of the load-bearing column 5. The other end of the reinforcing block 11 is welded and fixed to the upper surface of the support base 4. The reinforcing block 11 is triangular in shape, and there are several sets of reinforcing blocks 11. By setting the reinforcing block 11, the stability of the triangular structure is used to disperse the vertical load and horizontal force borne by the load-bearing column 5, reduce the stress concentration at the connection between the load-bearing column 5 and the support base 4, enhance the bending and deformation resistance of the load-bearing column 5, avoid the load-bearing column 5 from tilting or breaking due to long-term bearing or strong wind load, and extend the service life of the support.

[0032] In practical use: First, the mounting base 1 is fixed to the roof through the bolt holes 2 around the perimeter, providing basic support for the overall structure. Then, the support base 4 and the connecting base 72 are aligned, so that the connecting base 72 is inserted into the inner cavity of the connecting groove 71, and one end of the connecting base 72 is in contact with the surface of the limiting plate 74. Then, the positioning pin 75 is inserted into the positioning hole 73 on the upper surface of the support base 4. The movement range of the support base 4 is limited by the positioning pin 75 and the limiting plate 74, so as to realize the installation work between the frame and the mounting base 1. Then, according to the strong wind level of the installation area, the corresponding number of counterweights 6 are added. The counterweights 6 are inserted into the support groove 8 through the support block 9, so as to realize the assembly between the counterweights 6 and the load-bearing column 5.

[0033] Next, the fixing rod 102 is inserted into the movable hole 101 at the top of the load-bearing column 5. The fixing rod 102 passes through the movable hole 101 and extends into the fixing hole 103 of the support block 9 in the support groove 8. The movement range of the support block 9 in the support groove 8 is limited by mechanical locking, and the position of the connecting block in the connecting groove 71 is locked to realize the installation of the frame and the counterweight block 6. Finally, the adjusting frame 3 is bolted to the load-bearing column 5, and the photovoltaic solar panel is installed on the mounting plate 33. The mounting plate 33 is turned to rotate the photovoltaic solar panel. After the mounting plate 33 rotates around the bearing to the target angle, the threaded hole 35 on its surface is aligned with a set of adjusting holes 34 distributed in an arc on the surface of the adjusting plate 32. The self-locking bolt passes through the adjusting hole 34 and connects with the threaded hole 35 to lock the position of the mounting plate 33, thereby realizing the adjustment of the installation angle of the photovoltaic solar panel. The above scheme avoids the overall shaking or even overturning of the support in high wind speed areas, and avoids the support falling from the roof, which poses a double threat to the building structure and personnel safety.

[0034] 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.
