Description

Technical Field

[0001] This invention relates to the field of photovoltaic mounting systems, and in particular to a torsion-resistant photovoltaic mounting system tracking structure. Background Technology

[0002] With the widespread application of solar photovoltaic power generation technology, photovoltaic tracking systems have emerged to improve power generation efficiency. These systems enable photovoltaic modules to rotate according to the sun's position, thereby maximizing the absorption of solar radiation. They can be used for residential power supply in remote, unpowered areas, and are also widely used in transportation, communications, petroleum, marine, meteorological, and aerospace fields. Existing photovoltaic (PV) brackets are fixed in place and cannot adapt to complex or uneven terrain. During installation, if there is a height difference between the foundation anchor points, it will cause uneven stress on the support structure, thereby weakening the overall stability and torsional resistance of the structure. Furthermore, the lack of supporting structures between the connecting structures makes the PV brackets prone to torsion and deformation when exposed to strong wind loads for a long time. Therefore, it is necessary to increase the overall rigidity and wind load resistance of the PV brackets. Summary of the Invention

[0003] The technical problem this invention aims to solve is to overcome existing defects and provide a torsion-resistant photovoltaic (PV) support tracking structure. This structure uses a support rod and a main screw to connect the support frame and the PV support, improving the stability of the PV support. A liftable anchor plate is used to accommodate installation in different terrains. A secondary spring and bracket provide support for the angle-adjustable mounting frame. An electromagnet is used to fix the mounting frame in place. This design effectively improves the torsion resistance of the PV support, making it suitable for use in strong winds and severe weather, and effectively solving the problems in the prior art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a torsion-resistant photovoltaic support tracking structure, comprising a frame and a tracking unit: Frame: There are two frames, which are arranged in a left-right correspondence. Slide rods are slidably installed in the slide grooves on the front and rear sides of the frame. The outer end of the slide rod is connected to the top of the inner side of the bracket. A lifting rod is slidably installed inside the bracket. The bottom end of the lifting rod is connected to the middle of the top surface of the anchor plate. A support frame is provided in the middle of the bottom surface of the frame. An anti-torsion unit is provided on the inner side of the bracket. Tracking unit: includes a fixed shaft, a mounting frame, a transmission ring, a transmission gear, and a motor. The two ends of the fixed shaft are rotatably mounted to the middle of the inner side of the two frames. The two ends of the outer side of the fixed shaft are provided with mounting frames. The bottom surface of the two mounting frames is fixed with a transmission ring. The outer side of the transmission ring is evenly provided with tooth grooves. There are two motors, which are fixed to the outer side of the two support frames respectively. The output shaft of the motor is fixedly mounted with the transmission gear. The transmission gear meshes with the tooth grooves on the outer side of the transmission ring. It also includes a controller, which is fixed to the surface of the frame. The input terminal of the motor is electrically connected to the output terminal of the controller, and the input terminal of the controller is electrically connected to the output terminal of an external power source.

[0005] The sliding rod slides inside the frame to adjust the distance between the two anchor plates, while the lifting rod slides inside the bracket to adjust the height of the anchor plates. This makes the photovoltaic bracket suitable for complex or uneven terrain. The motor drives the transmission gear to mesh with the tooth grooves on the surface of the transmission ring to adjust the angle of the photovoltaic panels installed on the top surface of the mounting frame, thereby achieving sunlight tracking.

[0006] Furthermore, the tracking unit also includes a protective shell, a spring groove, a slider, a limiting block, and a main spring. There are two spring grooves, each opened on the inner side of one of the two support frames. The main spring is installed inside the spring groove, and the top of the main spring is connected to the bottom surface of the slider. The slider is slidably connected to the inside of the spring groove. The inner end of the slider is equipped with a protective shell. The extension of the main spring causes the slider to slide inside the spring groove, thereby covering the outside of the transmission gear and the transmission ring with the protective shell. This protects the transmission position and prevents foreign objects from entering and affecting subsequent adjustments.

[0007] Furthermore, the anti-torsion unit includes a connecting frame, a support rod, a main screw, a connector, a connecting plate, a plug-in plate, and a mounting frame. The connecting frame is fixed to the top of the inner side of the bracket. The support rod is rotatably installed inside the connecting frame. The screw hole inside the support rod is threadedly connected to the main screw. The main screw is rotatably installed on the top surface of the connector. Both ends of the outer side of the plug-in plate are fixed with connecting plates. The connecting plate is rotatably connected to the side of the connector. The mounting frame is fixed to the bottom of the side of the support frame. The mounting frame and the plug-in plate are correspondingly plugged in. The rotating main screw, in conjunction with the support rod, inserts the plug-in plate into the interior of the mounting frame. This forms a rigid and reliable anti-torsion connection between the support frame and the bracket, thereby improving the load-bearing capacity of the photovoltaic bracket against strong winds.

[0008] Furthermore, the anti-torsion unit also includes a frame, a sliding block, a mounting base, a secondary spring, and a bracket. The frame is disposed on the outer side of the bracket, and a secondary spring is fixed inside the frame. A sliding block is installed at the top of the secondary spring and is slidably installed inside the frame. A mounting base is disposed at the outer end of the sliding block and slides against the surface of the frame. A bracket is rotatably installed on the surface of the mounting base. The elasticity of the secondary spring cooperates with the sliding block to slide inside the frame, so that the bracket automatically fits against the bottom surface of the placement frame during the photovoltaic panel tracking and adjustment process to play an auxiliary support role.

[0009] Furthermore, the anti-torsion unit also includes a fixed frame, a secondary screw, and a rotating wheel. The fixed frame is fixed to the bottom end of the support frame. The secondary screw is threaded into the screw holes on both the front and rear sides of the fixed frame. The secondary screw is rotatably mounted on the bottom end of the inner side of the bracket. A rotating wheel is fixed to the inner end of the secondary screw. Rotating the rotating wheel to drive the secondary screw to rotate can adjust the distance between the two brackets.

[0010] Furthermore, the anti-torsion unit also includes a rubber pad and a locking bolt. The rubber pad is bonded to the inner side of the plug plate, and the locking bolt is threaded into the screw hole on the surface of the mounting bracket and inserted into the locking hole on the surface of the plug plate. The locking bolt is threaded into the screw hole on the mounting bracket and inserted into the locking hole to fix the plug plate, and works with the rubber pad to effectively buffer vibration and enhance locking friction.

[0011] Furthermore, the anti-torsion unit also includes an electromagnet, which is installed in a groove inside the bracket. The input end of the electromagnet is electrically connected to the output end of the controller. When the electromagnet is energized, it magnetically fixes the placement frame to reduce the torsional force generated by strong winds on the fixed shaft.

[0012] Furthermore, it also includes shaft holes, fixing bolts, and fixing holes. There are two shaft holes, which are opened vertically and vertically at the bottom of the outer side of the bracket. Fixing bolts are installed in the internal threads of the shaft holes. The fixing holes are evenly opened on the outer side of the lifting rod. The fixing bolts installed in the internal threads of the shaft holes are inserted into the fixing holes for fixation, thereby fixing the height of the lifting rod.

[0013] Furthermore, it also includes a light sensor and a frame. There are two frames, each set in the middle of the top surface of two corresponding frames. A light sensor is snapped into the inside of the frame. The output of the light sensor is electrically connected to the input of the controller. The light sensor inside the frame can sense the position of the sun in real time, thereby automatically adjusting the angle of the photovoltaic panel to maximize sunlight capture.

[0014] Furthermore, the sliding rod, bracket, and lifting rod are all made of high-strength structural steel, and the surfaces of the sliding rod, bracket, and lifting rod are all coated with a thickened galvanized coating. The use of high-strength structural steel can increase the overall strength of the photovoltaic bracket, and the thickened galvanized coating can effectively resist corrosion from the outdoor environment.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This anti-torsional photovoltaic support tracking structure has the following advantages: 1. The distance between the two anchor plates is adjusted by sliding the sliding rod inside the frame, while the height of the anchor plates is adjusted by sliding the lifting rod inside the bracket. This makes the photovoltaic bracket suitable for complex or uneven terrain. The rotating main screw, together with the support rod, inserts the plug plate into the inside of the mounting frame. This forms a rigid and reliable torsional connection between the support frame and the bracket, thereby improving the load of the photovoltaic bracket against strong winds.

[0016] 2. The angle of the photovoltaic panel installed on the top surface of the mounting frame is adjusted by the meshing of the transmission gear with the tooth groove on the surface of the transmission ring driven by the motor, thereby achieving the tracking of sunlight. The light sensor inside the frame can sense the position of the sun in real time, thereby automatically adjusting the angle of the photovoltaic panel to maximize the capture of sunlight.

[0017] 3. The main spring extends, causing the slider to slide inside the spring groove, thereby covering the outer side of the transmission gear and transmission ring with a protective shell. This protects the transmission position and prevents foreign objects from entering and affecting subsequent adjustments.

[0018] 4. The sliding block slides inside the frame through the elastic cooperation of the auxiliary spring, so that the bracket automatically fits with the bottom surface of the placement frame during the photovoltaic panel tracking and adjustment process to play an auxiliary support role. When the electromagnet is energized, it magnetically fixes the placement frame to reduce the torsional force generated by strong wind on the fixed shaft. Attached Figure Description

Frame 1: Two frames are arranged symmetrically on the left and right sides. Sliding rods 4 are slidably installed in the grooves on both the front and rear sides of frame 1.

The anti-torsion unit 3 includes a connecting frame 31, a support rod 32, a main screw 33, a connector 34, a connecting plate 35, a plug-in plate 36, and a mounting frame 37. The connecting frame 31 is fixed to the top of the inner side of the bracket 5. The support rod 32 is rotatably installed inside the connecting frame 31. The screw hole inside the support rod 32 is threadedly connected to the main screw 33. The main screw 33 is rotatably installed on the top surface of the connector 34. Both ends of the outer side of the plug-in plate 36 are fixed with connecting plates 35. The connecting plates 35 are rotatably connected to the side of the connector 34. The mounting bracket 37 is fixed to the bottom of the side of the support frame 8. The mounting bracket 37 and the plug-in plate 36 are correspondingly plugged in. The rotating main screw 32 cooperates with the support rod 32 to insert the plug-in plate 36 into the interior of the mounting bracket 37. This can form a rigid and reliable anti-torsional connection between the support frame 8 and the bracket 5 to improve the load of the photovoltaic bracket for strong winds. The anti-torsional unit 3 also includes a frame 38, a sliding block 39, a mounting base 310, a secondary spring 311, and a bracket 312. The frame 38 is set on the outer side of the bracket 5.

A mounting base 310 is provided on the outer end of the sliding block 39, which slides against the surface of the frame 28. A bracket 312 is rotatably mounted on the surface of the mounting base 310. The elasticity of the secondary spring 311 cooperates with the sliding block 39 to slide inside the frame 38, allowing the bracket 312 to automatically conform to the bottom surface of the placement rack 22 during photovoltaic panel tracking adjustment, thus providing auxiliary support. The anti-torsion unit 3 also includes a fixing frame 313, a secondary screw 314, and a rotating wheel 315. The fixing frame 313 is fixed to the bottom end of the support frame 8. The secondary screw 314 is threaded into the screw holes on both the front and rear sides of the fixing frame 313. The secondary screw 314 is rotatably installed on the bottom end of the inner side of the bracket 5. A rotating wheel 315 is fixed to the inner end of the secondary screw 314. Rotating the rotating wheel 315... Rotating the moving screw 314 adjusts the distance between the two supports 5. The anti-torsion unit 3 also includes a rubber pad 316 and a locking bolt 317. The rubber pad 316 is adhered to the inner side of the plug-in plate 36. The locking bolt 317 is threaded into the screw hole on the surface of the mounting bracket 37 and inserted into the locking hole on the surface of the plug-in plate 36. The locking bolt 317, in conjunction with the screw hole on the mounting bracket 37, is threaded into the locking hole to fix the plug-in plate 36. It also works with the rubber pad 316 to effectively buffer vibration and enhance locking friction. The anti-torsion unit 3 also includes an electromagnet 318, which is installed in a groove inside the bracket 312. The input end of the electromagnet 318 is electrically connected to the output end of the controller 14. When the electromagnet 318 is energized, it magnetically fixes the placement bracket 22.To reduce the torsional force exerted by strong winds on the fixed shaft 21; Tracking unit 2 includes a fixed shaft 21, a mounting bracket 22, a transmission ring 23, a transmission gear 24, and a motor 25. The two ends of the fixed shaft 21 are rotatably mounted to the middle of the inner sides of the two frames 1. Mounting brackets 22 are provided at both ends of the outer side of the fixed shaft 21. Transmission rings 23 are fixed to the bottom surface of each mounting bracket 22. The outer side of the transmission rings 23 has evenly spaced toothed grooves. There are two motors 25, each fixed to the outer side of one of the two support frames 8. The output shaft of the motor 25 is fixedly mounted to the transmission gear 24, which meshes with the toothed grooves on the outer side of the transmission ring 23. Tracking unit 2 also includes a protective shell 26. The system includes a spring groove 27, a slider 28, a limiting block 29, and a main spring 210. There are two spring grooves 27, which are respectively opened on the inner side of the two support frames 8. The main spring 210 is installed inside the spring groove 27. The top of the main spring 210 is connected to the bottom surface of the slider 28. The slider 28 is slidably connected to the inside of the spring groove 27. A protective shell 26 is installed on the inner end of the slider 28. When the main spring 210 extends, the slider 28 slides inside the spring groove 27, thereby covering the outside of the transmission gear 24 and the transmission ring 23 with the protective shell 26. This protects the transmission position and prevents foreign objects from entering and affecting subsequent adjustments. The system also includes a controller 14, which is fixed to the surface of the frame 1. The input of the motor 25 is electrically connected to the output of the controller 14, and the input of the controller 14 is electrically connected to the output of an external power source. The slide bar 4 slides inside the frame 1 to adjust the distance between the two anchor plates 7, while the lifting rod 6 slides inside the bracket 5 to adjust the height of the anchor plates 7. This allows the photovoltaic bracket to be suitable for complex or uneven terrain. The motor 25 drives the transmission gear 24 to mesh with the tooth grooves on the surface of the transmission ring 23 to adjust the angle of the photovoltaic panels installed on the top surface of the placement frame 22, thereby achieving sunlight tracking. The system also includes shaft holes 9, fixing bolts 10, and fixing holes 11. There are two shaft holes 9, which are opened vertically and vertically on the bottom of the outer side of the bracket 5. The internal threads of the shaft holes 9 are used to install the fixing bolts 10. The fixing holes 11 are evenly opened on the outer side of the lifting rod 6. On the side, the fixing bolts 10, which are threaded inside the shaft hole 9, are inserted into the fixing hole 11 for fixation, thereby fixing the height of the lifting rod 6. It also includes a light sensor 12 and a frame 13. There are two frames 13, which are respectively set in the middle of the top surface of the two corresponding frames 1. The light sensor 12 is snapped into the inside of the frame 13. The output end of the light sensor 12 is electrically connected to the input end of the controller 14. The light sensor 12 inside the frame 13 can sense the position of the sun in real time, thereby automatically adjusting the angle of the photovoltaic panel to maximize the capture of sunlight. The slide rod 4, the bracket 5 and the lifting rod 6 are all made of high structural steel. The surfaces of the slide rod 4, the bracket 5 and the lifting rod 6 are all covered with a thickened galvanized coating. The use of high structural steel can increase the overall strength of the photovoltaic bracket, and the thickened galvanized coating can effectively resist the corrosion of the outdoor environment.

[0027] The working principle of the anti-torsion photovoltaic bracket tracking structure provided by this invention is as follows: First, adjust the positions of the two anchor plates 7 according to the installation location. Rotate the rotating wheel 315 to drive the auxiliary screw 314 to rotate, and cooperate with the sliding rod 4 to slide inside the frame 1 to adjust the spacing of the brackets 5. The self-locking characteristic of the auxiliary screw 314 is used for fixing. Then, the lifting rod 6 slides inside the bracket 5 to adjust the height of the anchor plates 7. The fixing bolt 10, which is threaded inside the shaft hole 9, is inserted into the fixing hole 11 for fixing, thereby fixing the height of the lifting rod 6. This allows the photovoltaic bracket to be installed on complex ground surfaces of different heights. Subsequently, rotate the main screw 33 to adjust the distance between the support rod 32 and the plug plate 36, and insert the plug plate 36 into the mounting frame 37. The locking bolt 317 is threaded into the screw hole of the mounting frame 37 and inserted into the locking hole to fix the plug plate 36. The rubber pad 316 is used to effectively buffer vibration and enhance the locking friction, thus providing a connection between the support frame 8 and the bracket 5. A rigid and reliable torsional connection is formed between them to improve the load of the photovoltaic bracket against strong winds. The light sensor 12 inside the bracket 13 can sense the position of the sun in real time and start the motor 25 according to the position of the sunlight. The motor 25 drives the transmission gear 24 to mesh with the tooth groove on the surface of the transmission ring 23 to adjust the angle of the photovoltaic panel installed on the top surface of the placement frame 22, thereby achieving sunlight tracking. At the same time, the elastic sliding block 39 of the auxiliary spring 311 slides inside the frame 38, so that the bracket 312 automatically fits against the bottom surface of the placement frame 22 during the photovoltaic panel tracking adjustment process to play an auxiliary support role. After the adjustment is completed, the electromagnet 318 is energized to magnetically fix the placement frame 22 to reduce the torsional force generated by the strong wind on the fixed shaft 21. Finally, the main spring 210 extends to make the slider 28 slide inside the spring groove 27, thereby covering the outside of the transmission gear 24 and the transmission ring 23 with the protective shell 26, which protects the transmission position and prevents foreign objects from entering and affecting subsequent adjustments.
