Description

Technical Field

[0001] This invention relates to the field of photovoltaic installation equipment, and more specifically, to a photovoltaic installation bracket and its installation method for steep slope terrain. Background Technology

[0002] Photovoltaics refers to the technology and process of directly converting sunlight into electrical energy. The core of this technology is the photovoltaic effect, which is that when photons strike semiconductor materials (such as silicon), they can excite electrons to be released from their atoms, thereby generating an electric current. Photovoltaic mounting brackets are structural systems used to fix solar photovoltaic panels, ensuring that the photovoltaic panels can face the sun at the optimal angle, thereby maximizing energy collection efficiency. The design of photovoltaic mounting brackets will also vary depending on different application scenarios and environmental conditions.

[0003] There are many common types of photovoltaic (PV) mounting systems. For example, ground-mounted systems are suitable for open areas or situations where roof area is insufficient, supporting large-scale solar arrays; roof-mounted systems are installed directly on the roof of a building, saving space, and have different fixing methods depending on the roof material (such as tiles, metal, etc.). Considering the safety of the building structure, a detailed engineering assessment is required; tracking mounting systems are divided into single-axis and dual-axis types, which can automatically adjust the direction of the PV panels to follow the movement of the sun. By properly selecting and installing PV mounting systems, not only can the efficiency of solar energy utilization be improved, but the service life of the PV system can also be extended, ensuring its stable operation.

[0004] In practical applications, existing technologies often fail to adapt to varying terrain slopes when installing photovoltaic systems on hillsides or other areas with abundant but underdeveloped solar energy resources. This is because traditional support structures are typically designed for flat ground. However, they cannot flexibly adjust the height and angle to accommodate different terrain gradients, increasing construction difficulty. Furthermore, when installed on slopes, the overall center of gravity of the traditional support structure deviates from the vertical direction, increasing the risk of tipping over. Therefore, to address these technical issues, it is necessary to provide a photovoltaic installation support structure and its installation method for steep terrain. Summary of the Invention

[0005] The purpose of this invention is to provide a photovoltaic mounting bracket and its installation method for steep slope terrain, so as to solve the above-mentioned problems.

[0006] To achieve the above objectives, an embodiment of the present invention provides the following technical solution:

[0007] A photovoltaic mounting bracket and its installation method for steep slope terrain are disclosed, comprising a bracket, a traction chain, and a counterweight. A telescopic rod is inserted into the inner cavity of the bracket. A base is hinged to the lower end of the bracket. A pressure sensor is embedded and fixedly connected to the lower surface of the base. Multiple limiting holes are evenly distributed on the upper surface of the base. A controller is fixedly connected to the upper surface of the base. A mounting frame is installed at the upper end of the telescopic rod. A photovoltaic panel is mounted on the upper surface of the mounting frame. Two chains are symmetrically hinged to the upper surface of the base. A rotating rod is rotatably connected to the inner cavity of the bracket. Sprockets are fixedly connected to both ends of the rotating rod through the bracket. A worm gear is fixedly connected to the middle of the outer surface of the rotating rod within the inner cavity of the bracket. A worm is meshed with the outer surface of the worm gear. A counterweight is slidably connected to the inner cavity of the base. A movable plate is fixedly connected to one side of the counterweight. An electric push rod is fixedly connected to the upper surface of the movable plate. An L-shaped insert is fixedly connected to the upper end of the electric push rod. Multiple electromagnets are evenly embedded and fixedly connected to the top of the inner cavity of the base. A quick-fixing component is installed within the inner cavity of the counterweight.

[0008] As a further improvement of the present invention, a plug rod is inserted into the inner cavity of the bracket and the limiting hole, and a spring is sleeved on the outer surface of the plug rod. The two ends of the spring are fixedly connected to the handle of the plug rod and the outer surface of the bracket, respectively.

[0009] As a further improvement of the present invention, the controller is electrically connected to the pressure sensor, the electromagnet and the electric push rod respectively, and the number of electromagnets and the limiting holes are the same.

[0010] As a further improvement of the present invention, a connecting rod is rotatably connected to the inner cavity of the upper end of the telescopic rod, and a square frame is fixedly connected to the outer surfaces of both ends of the connecting rod through lugs. The upper surface of the square frame is fixedly connected to the lower surface of the photovoltaic panel.

[0011] As a further improvement of the present invention, a gear is fixedly connected to one end of the connecting rod, a motor is fixedly connected to one side of the telescopic rod, and a drive gear is fixedly connected to the output shaft end of the motor through the telescopic rod, and the gear and the drive gear are meshed together.

[0012] As a further improvement of the present invention, the chain is meshed with the sprocket, and two L-shaped limiting plates are symmetrically fixedly connected on both sides of the bracket, with the chain and sprocket located between the limiting plates and the bracket.

[0013] As a further improvement of the present invention, one end of the worm gear is rotatably connected to the inner cavity side wall of the bracket, a drive motor is fixedly connected to one side of the bracket, and the output shaft end of the drive motor passes through the bracket and is fixedly connected to the other end of the worm gear.

[0014] As a further improvement of the present invention, a magnetic block is embedded in the inner cavity of the upper surface of the counterweight block, the magnetic block is magnetically connected to the electromagnet, a sliding groove is provided on one side of the base, the moving plate moves in the inner cavity of the sliding groove on one side of the base, and the lower end of the L-shaped plug moves in the inner cavity of the limiting hole.

[0015] As a further improvement of the present invention, the quick-fixing component includes a cylindrical glue groove formed in the inner cavity of the counterweight, the inner cavity of the glue groove is filled with adhesive, a sealing membrane is fixedly connected to the lower opening of the glue groove, a sealing plug is movably connected to the inner cavity of the glue groove, a puncture needle is fixedly connected to the middle of the lower surface of the sealing plug, and telescopic rods are symmetrically fixedly connected to the upper surface of the sealing plug. The upper end of the telescopic rod is fixedly connected to the top of the inner cavity of the counterweight, and a connecting spring is sleeved on the outer surface of the telescopic rod. The two ends of the connecting spring are fixedly connected to the top of the inner cavity of the counterweight and the upper surface of the sealing plug, respectively.

[0016] A method for installing photovoltaic mounting brackets on steep slopes includes the following steps:

[0017] S1: The base is installed on the base floor with bolts. The height of the telescopic rod is changed by inserting the plug into the limiting holes at different positions on the telescopic rod. The photovoltaic panel is fixedly installed on the mounting frame, and the angle of the photovoltaic panel is changed by the mounting frame.

[0018] S2: The worm and worm wheel work together to drive the sprocket to rotate and move the chain, changing the angle of the base;

[0019] S3: The electromagnet is activated to move the counterweight by magnetic attraction, changing the center of gravity of the base. The pressure sensor monitors whether the base is loose from the ground and activates the quick-fix device to temporarily reinforce the base.

[0020] Compared with the prior art, the advantages of this invention are:

[0021] (1) This solution adjusts the height of the telescopic rod by pulling the plug outward to move it away from the inner cavity of the adjustment hole. The operator can install the photovoltaic panel at a suitable height according to actual needs. The photovoltaic panel is fixedly installed on the square frame, which provides all-round support. The motor drives the drive gear to rotate. When the drive gear rotates, it drives the gear and connecting rod to rotate, adjusting the angle of the photovoltaic panel. This realizes the automatic angle adjustment of the photovoltaic panel, adapts to changes in different times and seasons, achieves all-weather tracking of light, and improves power generation efficiency.

[0022] (2) This solution uses a pressure sensor to detect the contact pressure between the base and the base surface. When the pressure value reaches the preset value, it means that the base is firmly installed on the base surface. It monitors in real time and helps operators judge whether the base is installed stably. It starts the drive motor and drives the rotating rod and sprocket to rotate and pull the chain to move, thereby pulling the base to adjust its tilt angle, ensuring that the base fits the slope of the base surface, and solving the problem that traditional brackets are difficult to fix on steep slopes.

[0023] (3) This scheme selects the appropriate position of the electromagnet by tilting the base to attract the magnetic block and drive the counterweight block to move to the appropriate position in the base. The counterweight block changes the center of gravity of the device, thereby improving the overall stability, enhancing wind resistance and stability. The counterweight block moves in the direction of the tilted end of the base, realizing dynamic balance adjustment, offsetting the tilting moment caused by the slope, reducing structural damage caused by long-term tilting or instability, and extending the service life of the entire device.

[0024] (4) This solution uses a pressure sensor to monitor the pressure between the base and the ground in real time and transmits it to the controller. When the two become loose, the pressure value decreases. The controller can identify the loose installation in time based on the data change and trigger the temporary reinforcement function. At the same time, it sends an early warning to the operator to remind him to carry out maintenance in time. The controller controls the electric push rod to drive the L-shaped plug to move downward a second time, push the sealing plug downward to puncture the sealing membrane through the piercing needle, and push the adhesive in the glue groove to seep downward to fill the gap between the base and the base floor. The adhesive is used to temporarily stick and fix the base and the base floor to prevent them from becoming loose and to buy time for the operator to carry out maintenance.

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0035] Example 1:

[0036] Please see Figure 1-3 A photovoltaic mounting bracket and its installation method for steep slope terrain includes a bracket 1 and a counterweight 7. A telescopic rod 101 is inserted into the inner cavity of the bracket 1. A base 2 is hinged to the lower end of the bracket 1. A pressure sensor 201 is embedded and fixedly connected to the lower surface of the base 2. Multiple limiting holes 202 are evenly opened on the upper surface of the base 2. A controller 203 is fixedly connected to the upper surface of the base 2. An installation frame 3 is installed on the upper end of the telescopic rod 101. A photovoltaic panel 4 is installed on the upper surface of the installation frame 3.

[0037] Specifically, a rod 103 is inserted into the inner cavity of the bracket 1 and the limiting hole 202. A spring 104 is sleeved on the outer surface of the rod 103. The two ends of the spring 104 are fixedly connected to the handle of the rod 103 and the outer surface of the bracket 1, respectively. The controller 203 is electrically connected to the pressure sensor 201 and the electric push rod 704, respectively. A gear 303 is fixedly connected to one end of the connecting rod 301. A motor 304 is fixedly connected to one side of the telescopic rod 101. The output shaft of the motor 304 passes through the telescopic rod 101 and is fixedly connected to the drive gear 305. The gear 303 and the drive gear 305 are meshed together.

[0038] Furthermore, the bracket 1 provides stable support for the entire device. The operator pulls the insertion rod 103 outward to move it away from the inner cavity of the adjustment hole 102 and squeezes the spring 104. At this time, the telescopic rod 101 loses its fixed limit and can be adjusted in height. There are multiple adjustment holes 102, and the distance between each pair is the same. The spring 104 itself drives the insertion rod 103 to automatically return to its original position and enter the inner cavity of another adjustment hole 102, locking the adjusted telescopic rod 101 at the required height. The operator can install the photovoltaic panel 4 at a suitable height according to actual needs and can flexibly adjust it according to changes in terrain and requirements.

[0039] The photovoltaic panel 4 is fixedly installed on the square frame 302, which provides all-round support. The starting motor 304 drives the drive gear 305 to rotate. When the drive gear 305 rotates, it drives the gear 303 and the connecting rod 301 to rotate, adjusting the angle of the photovoltaic panel 4. This realizes the automatic angle adjustment of the photovoltaic panel 4, adapting to changes in different times and seasons, achieving all-weather tracking of sunlight, and improving power generation efficiency.

[0040] The base 2 is fixedly installed on the base surface by bolts or nails. The base surface is generally a concrete surface, which has stability and load-bearing capacity. The pressure sensor 201 detects the contact pressure between the base 2 and the base surface. When the pressure value reaches the preset value, it means that the base 2 is firmly installed on the base surface. Real-time monitoring helps the operator judge whether the base 2 is installed stably and ensures the qualified installation.

[0041] Example 2:

[0042] Please see Figure 1 , Figure 2 , Figure 4 and Figure 5A photovoltaic mounting bracket and its installation method for steep slope terrain includes two chains 501 symmetrically hinged to the upper surface of a base 2. A rotating rod 502 is rotatably connected to the inner cavity of the bracket 1. Both ends of the rotating rod 502 are fixedly connected to sprockets 503 through the bracket 1. A worm gear 504 is fixedly connected to the middle of the outer surface of the rotating rod 502 in the inner cavity of the bracket 1. A worm 505 is meshed with the outer surface of the worm gear 504.

[0043] Specifically, chain 501 is meshed with sprocket 503, and two L-shaped limiting plates 6 are symmetrically fixedly connected on both sides of bracket 1. Chain 501 and sprocket 503 are located between limiting plates 6 and bracket 1. One end of worm gear 505 is rotatably connected to the inner cavity side wall of bracket 1. A drive motor 506 is fixedly connected to one side of bracket 1, and the output shaft end of drive motor 506 passes through bracket 1 and is fixedly connected to the other end of worm gear 505.

[0044] Furthermore, when the base 2 needs to be installed on terrain with a certain slope, the drive motor 506 is started and driven by the worm gear 505 and worm wheel 504 to rotate the rotating rod 502 and sprocket 503. When the sprocket 503 rotates, it will pull the chain 501 to move, thereby pulling the base 2 to adjust its tilt angle and ensure that the base 2 is in contact with the slope of the base surface. The worm gear 505 and worm wheel 504 have self-locking properties, which can ensure that the worm wheel 504 will not rotate arbitrarily. When the sprocket 503 rotates, it will drive the chain 501 to move. When it does not rotate, the chain 501 will not move arbitrarily.

[0045] The limiting plate 6 acts as a limiting component to prevent the chain 501 from falling off the side of the sprocket 503. The chain 501 can also provide a certain traction force for the bracket 1, thereby ensuring the stability of the bracket 1. At the same time, the chain 501 is relatively easy to repair and replace, and is easier to carry and maintain than traditional brackets.

[0046] Example 3:

[0047] Please see Figure 1 , Figure 2 , Figure 4 , Figure 6 and Figure 7 A photovoltaic mounting bracket and its installation method for steep slope terrain includes a counterweight 701 slidably connected to the inner cavity of a base 2, a movable plate 703 fixedly connected to one side of the counterweight 701, an electric push rod 704 fixedly connected to the upper surface of the movable plate 703, an L-shaped insert rod 705 fixedly connected to the upper end of the electric push rod 704, a plurality of electromagnets 8 evenly embedded and fixedly connected to the top of the inner cavity of the base 2, and a quick-fixing component 9 installed in the inner cavity of the counterweight 701.

[0048] Specifically, with the same number of limiting holes 202, the controller 203 is electrically connected to the electromagnet 8. A magnetic block 702 is embedded in the inner cavity of the upper surface of the counterweight 701, and the magnetic block 702 is magnetically connected to the electromagnet 8. A sliding groove is provided on one side of the base 2, and the moving plate 703 moves within the inner cavity of the sliding groove on one side of the base 2. The lower end of the L-shaped insert 705 moves within the inner cavity of the limiting hole 202. The quick-fixing component 9 includes a cylindrical glue groove 901 opened in the inner cavity of the counterweight 701, and the inner cavity of the glue groove 901 is filled with adhesive. A sealing membrane 902 is fixedly connected to the lower opening of 01. A sealing plug 903 is movably connected to the inner cavity of the glue groove 901. A puncture needle 904 is fixedly connected to the middle of the lower surface of the sealing plug 903. Telescopic rods 905 are symmetrically fixedly connected to the upper surface of the sealing plug 903. The upper end of the telescopic rod 905 is fixedly connected to the top of the inner cavity of the counterweight block 701. A connecting spring 906 is sleeved on the outer surface of the telescopic rod 905. The two ends of the connecting spring 906 are fixedly connected to the top of the inner cavity of the counterweight block 701 and the upper surface of the sealing plug 903, respectively.

[0049] Furthermore, when the base 2 is installed on a slope, its overall center of gravity will be offset to a certain extent compared to a traditional flat base. At this time, the electromagnet 8 can be activated at a suitable position according to the tilt angle of the base 2 to attract the magnetic block 702 and drive the counterweight block 701 to move to a suitable position inside the base 2. By changing the center of gravity of the device through the counterweight block 701, the overall stability is improved, and the wind resistance and stability are enhanced, especially on terrain with a large slope.

[0050] The magnetic block 702 acts as an adsorption metal component, working with the electromagnet 8 to move the counterweight 701. Multiple electromagnets 8 are provided, allowing them to be moved to different positions. The counterweight 701 moves flexibly according to the different angles of the base 2. The direction of movement of the counterweight 701 is towards the tilted end of the base 2, achieving dynamic balance adjustment and counteracting the tilting torque caused by the slope.

[0051] When the counterweight 701 moves to the designated position, the electric push rod 704 is activated to drive the L-shaped insert rod 705 downward to enter the inner cavity of the adjustment hole 102, thereby positioning the adjusted counterweight 701. The number of adjustment holes 102 and electromagnets 8 is the same, and their corresponding center lines are on the same horizontal line. The first downward movement of the L-shaped insert rod 705 is exactly at the upper end of the sealing plug 903, providing only a limiting function to restrict the position of the counterweight 701.

[0052] When the connection between the base 2 and the ground becomes loose after prolonged use, the pressure sensor 201 will monitor the decrease in pressure in real time and transmit the data to the controller 203. The controller 203 will promptly identify the loose installation based on the data change and trigger the temporary reinforcement function. At the same time, it will send an early warning to the operator to remind them to carry out maintenance in time. The controller 203 will control the electric push rod 704 to drive the L-shaped plug 705 to move downward for the second time, pushing the sealing plug 903 downward to puncture the sealing membrane 902 through the piercing needle 904, and pushing the adhesive in the glue groove 901 to seep downward and fill the loose gap between the base 2 and the base ground. The adhesive will temporarily stick and fix the base 2 and the base ground to prevent them from loosening further, giving the operator time for maintenance.

[0053] The adhesive is a single-component glue that cures upon contact with air, such as silicone sealant, polyurethane sealant, and modified silane sealant. Its characteristic is that it will undergo a rapid chemical reaction and cure upon exposure to air, allowing for quick connection between the base 2 and the base surface. The sealing film 902 and the sealing plug 903 work together to isolate external air and prevent the adhesive from contacting the air. Both the sealing film 902 and the sealing plug 903 are made of high-barrier materials, such as multi-layer composite film bags, and it is necessary to ensure a tight seal. Alternatively, special packaging materials designed for chemicals with good moisture-proof properties can be selected, as long as the sealing is tight. After the L-shaped insert 705 is removed, the sealing plug 903 is automatically reset by the elastic force of the connecting spring 906.

[0054] Working principle: During device use, the operator pulls the insertion rod 103 outward, causing it to leave the inner cavity of the adjustment hole 102 and compressing the spring 104. At this time, the telescopic rod 101 loses its fixed limit, allowing for height adjustment. The spring 104's own elasticity causes the insertion rod 103 to automatically return to its original position and enter the inner cavity of the adjustment hole 102 at another position, locking the adjusted telescopic rod 101 at the desired height. The photovoltaic panel 4 is fixedly installed on the square frame 302. The starting motor 304 drives the drive gear 305 to rotate. When the drive gear 305 rotates, it drives the gear 303 and the connecting rod 301 to rotate, adjusting the height. The angle of the photovoltaic panel 4 is adjusted, and then the base 2 is fixed to the base surface with bolts or nails. The contact pressure between the base 2 and the base surface is detected by the pressure sensor 201 to help the operator determine whether the base 2 is installed stably. When the base 2 needs to be installed on terrain with a certain slope, the drive motor 506 can be started to drive the rotating rod 502 and the sprocket 503 to rotate through the transmission of the worm gear 505 and the worm wheel 504. When the sprocket 503 rotates, it will pull the chain 501 to move, thereby pulling the base 2 to adjust its tilt angle, ensuring that the base 2 is in contact with the slope of the base surface. At the same time, according to the tilt of the base 2... The electromagnet 8, activated at a suitable angle, attracts the magnetic block 702, which in turn moves the counterweight 701 to a suitable position within the base 2. The counterweight 701 alters the device's center of gravity, improving overall stability and counteracting the tilting torque caused by the slope. The electric push rod 704 then moves the L-shaped insert rod 705 downwards into the inner cavity of the adjustment hole 102, positioning the adjusted counterweight 701. When the connection between the base 2 and the ground becomes loose after prolonged use, the pressure sensor 201 detects the decrease in pressure in real time and transmits the data to the controller 203. The controller 203 adjusts the settings based on the data. The system promptly detects any loose installation and triggers a temporary reinforcement function. Simultaneously, it sends a warning to the operator to remind them to perform timely maintenance. The controller 203 then controls the electric push rod 704 to move the L-shaped insert rod 705 downwards a second time, pushing the sealing plug 903 downwards. This causes the sealing membrane 902 to be punctured by the piercing needle 904, and the adhesive in the glue groove 901 to leak downwards, filling the loose gap between the base 2 and the base surface. The adhesive then temporarily bonds and fixes the base 2 and the base surface. After the L-shaped insert rod 705 is removed, the sealing plug 903 automatically resets due to the elasticity of the connecting spring 906.
