Description

Technical Field

[0001] This invention relates to the field of photovoltaic panel protection, and in particular to an impact-resistant protection structure for the edge of a photovoltaic panel. Background Technology

[0002] With the increasing global demand for renewable energy, solar photovoltaic (PV) power generation technology has been widely adopted. As the core component of a solar power system, PV panels are typically exposed to the outdoor environment on a large scale and for extended periods, inevitably subjecting themselves to various external impacts and stresses. The edges of PV panels are particularly vulnerable, easily damaged during transportation, installation, and daily operation by bumps, falling objects (such as hail or gravel), or improper handling. Edge cracks or micro-cracks not only affect the aesthetics of the PV panel but also severely damage its internal circuitry, leading to decreased power generation efficiency, accelerated power decay, and even premature failure of the entire module, resulting in significant economic losses.

[0003] Protection of photovoltaic panels mainly focuses on improving the strength of the overall support structure and surface glass, but there is a relative lack of targeted protection measures for the edge areas. Since the contact is mostly rigid, it cannot effectively absorb and disperse impact energy, resulting in limited protection. Furthermore, in strong winds or vibration environments, the protective structure is prone to loosening, and may even damage the photovoltaic panel itself due to friction. Therefore, an impact-resistant protection structure for the edge of photovoltaic panels is proposed. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the existing defects and provide an impact-resistant protection structure for the edge of a photovoltaic panel. The main buffer spring, the secondary buffer spring, the damping buffer and the friction buffer can provide multi-directional impact protection for the edge of the photovoltaic panel. The fixing rod can connect multiple fixing seats to the frame and fix them by clamping. At the same time, the rubber pad and the protective pad can increase the fixing firmness and prevent wear. This invention can effectively solve the problems in the background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an impact-resistant protection structure for the edge of a photovoltaic panel, comprising a fixing base and a protective unit:

[0006] Fixing base: The surface is provided with an adjustment groove, the fixing base is provided with a fixing unit inside, and the right side of the fixing base is equipped with a protective unit through a buffer unit;

[0007] The protective unit comprises a bracket, a frame, bolts, a fixing plate, a mounting groove, a mounting block, and a protective plate. The right side of the fixing plate has two corresponding frames, and the brackets are slidably installed inside the two frames. Screw holes are opened on both sides of the surface of the fixing plate. The bolts pass through the through holes on the surface of the brackets and are threaded into the screw holes on the surface of the fixing plate. The top of the bracket is fixed with a mounting block. The bottom surface of the protective plate has a mounting groove, and the mounting groove is slidably inserted into the mounting block.

[0008] The system also includes a frame, a connecting plate, and a support plate. The connecting plate is fixed to the right side of the frame, and the surface of the connecting plate has two corresponding through holes. The support plate is fixed to both the front and rear sides of the frame.

[0009] The bracket is installed into the frame using bolts, and the mounting block is slidably inserted into the mounting slot to install the protective plate. The protective plate can prevent damage to the photovoltaic panel from impacts such as hail.

[0010] Furthermore, the protective unit also includes fixing bolts and a support plate. The support plate is fixed to the right side of the bracket. The fixing bolts are installed in the screw holes on the surface of the support plate. The fixing bolts are inserted into the fixing holes on the bottom surface of the protective plate to fix the protective plate and facilitate subsequent disassembly.

[0011] Furthermore, the protective unit also includes transparent glass and a sponge pad. The transparent glass is installed on the top surface of the protective panel, and the sponge pad is adhered to the bottom surface of the protective panel. The transparent glass does not affect the light transmission of the photovoltaic panel, and it can self-clean when it rains to ensure the light efficiency of the area. The sponge pad can play a protective role when the protective panel is attached to the photovoltaic panel.

[0012] Furthermore, the buffer unit includes a main buffer spring, a side frame, a placement seat, a damping rod, a locking frame, a secondary buffer spring, a sliding plate, and a support frame. The side frame is fixed to the right side of the fixed seat. Main buffer springs are fixed to both sides inside the side frame. The main buffer springs are connected to one end of the left side of the placement seat. The middle part of the side frame is connected to one end of the damping rod, and the other end of the damping rod is connected to the middle part of the left side of the placement seat. A support frame is fixed to the bottom of the right side of the placement seat. The sliding plate is installed at the bottom of the left side of the fixed plate and slides inside the support frame. A secondary buffer spring is fixed to the top surface of the sliding plate. A locking frame is installed at the top of the secondary buffer spring and engages with the locking groove on the top surface of the support frame. The main buffer spring, in conjunction with the damping rod, can buffer lateral impacts, while the locking frame engages with the locking groove to install the fixed plate. The secondary buffer spring can buffer longitudinal impacts. This multi-directional impact protection structure effectively protects the edges of the photovoltaic panel.

[0013] Furthermore, the buffer unit also includes a T-slot, a T-block, a friction plate, a friction block, and a limiting plate. The T-slot is located in the middle of the right side of the placement seat. The T-block is fixed to the top of the left side of the fixing plate. There are two friction plates, which are fixed to the right side of the placement seat in a front-to-back manner. There are two friction blocks, which are fixed to the left side of the fixing plate in a front-to-back manner. The friction blocks are positioned corresponding to the friction plates. There are two limiting plates, which are fixed to the middle of the left side of the placement seat in a front-to-back manner. The limiting plates are slidably inserted into the limiting slot on the right side of the side frame. The T-block slides inside the T-slot, and the friction between the friction block and the friction plate converts the impact kinetic energy into heat energy, which can greatly reduce the impact force.

[0014] Furthermore, the fixing unit includes a bidirectional lead screw, an adjusting block, a rotating wheel, a fixing frame, and a locking screw. The bidirectional lead screw is rotatably installed in the adjusting groove inside the fixing seat. The threads at both ends of the bidirectional lead screw are opposite. The bottom end of the bidirectional lead screw is connected to the top end of the rotating wheel. There are two fixing frames, arranged vertically and vertically. An adjusting block is fixed to the right side of each fixing frame. The screw hole in the middle of the adjusting block is connected to the outer thread of the bidirectional lead screw. The locking screw is fixed to the top surface of the lower fixing frame and is slidably installed with a through hole on the surface of the upper fixing frame. Rotating the rotating wheel drives the bidirectional lead screw to rotate, thereby clamping the two fixing frames on both sides of the photovoltaic panel surface, making it suitable for use with photovoltaic panels of different specifications.

[0015] Furthermore, the fixing unit also includes a nut, an anti-detachment clip, a slider, a spring, and a fixing frame. The nut is threaded onto the outer side of the locking screw. The fixing frame is fixed to the top surface of the upper fixing bracket. The inside of the fixing frame is connected to one end of the spring, and the other end of the spring is connected to the left side of the slider. The slider is slidably installed inside the fixing frame. An anti-detachment clip is fixed to the top of the slider. Rotating the nut, in conjunction with the locking screw, locks the height of the fixing bracket. The spring extends, causing the anti-detachment clip to engage with the outside of the nut. This increases the firmness of the photovoltaic panel fixing and prevents loosening.

[0016] Furthermore, it also includes a Velcro insert, a Velcro nut, and a rubber pad. The Velcro nut is fixed to a groove on the inner side of the mounting bracket, and the Velcro insert is fixed to the outer side of the rubber pad. The Velcro insert is bonded to the Velcro nut, and the Velcro nut is bonded to the Velcro insert to install the rubber pad. This increases the friction with the photovoltaic panel surface, making the clamping more secure. Due to its softness, it avoids scratches or stress concentration that may be caused by direct contact between metal or hard components and the photovoltaic panel surface.

[0017] Furthermore, it also includes a main protective pad and a secondary protective pad. The main protective pad is fixed to the top surface inside the frame, and the secondary protective pad is fixed to the bottom surface inside the frame. Both the main and secondary protective pads are silicone pads. The main and secondary protective pads can protect the surface of the photovoltaic panel.

[0018] Furthermore, it also includes pole seats and fixing rods. There are four pole seats, which are fixed in pairs on the front and rear sides of the fixing seat. The inside of the pole seat is inserted into one end of the fixing rod, and the fixing rod is inserted into the through hole on the surface of the connecting plate. The fixing rod inside the pole seat can connect the fixing seat to the frame, so that the entire protective structure forms a complete rigid frame around the edge of the photovoltaic panel, which greatly enhances the overall structural strength and stability and effectively resists torsion and deformation.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: This photovoltaic panel edge impact protection structure has the following advantages:

[0020] 1. The bracket is installed into the frame by using bolts. The mounting block is slidably inserted into the mounting groove to install the protective plate. The protective plate is fixed by inserting the fixing bolts into the fixing holes on the bottom of the protective plate. The protective plate can prevent damage to the photovoltaic panel from the impact of objects such as hail. The transparent glass does not affect the light transmission of the photovoltaic panel, and it can also self-clean when it rains to ensure the light efficiency of the area.

[0021] 2. The main buffer spring, in conjunction with the damping rod, can buffer lateral impacts. The locking frame is inserted into the locking groove to install the fixing plate. The secondary buffer spring, in conjunction with the friction block and friction plate, converts the impact kinetic energy into heat energy for consumption, thus buffering longitudinal impacts. This multi-directional impact protection structure can effectively protect the edges of the photovoltaic panel.

[0022] 3. By rotating the rotating wheel, the bidirectional lead screw is driven to rotate, which in turn drives the two fixing brackets to clamp onto both sides of the photovoltaic panel surface. The rotating nut, in conjunction with the locking screw, locks the height of the fixing brackets. The spring extends and the anti-loosening bracket is locked on the outside of the nut. This increases the firmness of the photovoltaic panel fixing and prevents the problem of loosening. It is suitable for photovoltaic panels of different specifications.

[0023] 4. The rubber pad is installed by attaching the Velcro and Velcro tabs together, along with the main and secondary protective pads. This increases the friction with the photovoltaic panel surface, making the clamping more secure. Due to its softness, it avoids scratches or stress concentration that may be caused by direct contact between metal or hard components and the photovoltaic panel surface. Attached Figure Description

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figure 1-7This embodiment provides a technical solution: a photovoltaic panel edge impact protection structure, including a fixing base 1 and a protection unit 2.

[0035] Fixed base 1: An adjustment groove is provided on the surface of the fixed base 1. The fixed unit 4 is provided inside the fixed base 1. The fixed unit 4 includes a bidirectional lead screw 41, an adjustment block 42, a rotating wheel 43, a fixed frame 44, and a locking screw 45. The bidirectional lead screw 41 is rotatably installed in the adjustment groove inside the fixed base 1. The threads at both ends of the bidirectional lead screw 41 are opposite. The bottom end of the bidirectional lead screw 41 is connected to the top end of the rotating wheel 43. There are two fixed frames 44, which are arranged vertically and vertically. An adjustment block 42 is fixed on the right side of each of the two fixed frames 44. The screw hole in the middle of the adjustment block 42 is connected to the outer thread of the bidirectional lead screw 41. The locking screw 45 is fixed to the top surface of the lower fixed frame 44. The locking screw 45 is slidably installed with the through hole on the surface of the upper fixed frame 44. Rotating the rotating wheel 43 drives the bidirectional lead screw 41 to rotate. The rotating mechanism clamps two mounting brackets 44 onto both sides of the photovoltaic panel surface, adaptable to different specifications of photovoltaic panels. The mounting unit 4 also includes a nut 46, an anti-detachment clip 47, a slider 48, a spring 49, and a mounting frame 410. The nut 46 is threaded onto the outer side of the locking screw 45. The mounting frame 410 is fixed to the top surface of the upper mounting bracket 44. The interior of the mounting frame 410 is connected to one end of the spring 49, and the other end of the spring 49 is connected to the left side of the slider 48. The slider 48 is slidably mounted inside the mounting frame 410. The top of the slider 48 is fixed with the anti-detachment clip 47. Rotating the nut 46, in conjunction with the locking screw 45, locks the height of the mounting bracket 44, and the spring 39 extends, causing the anti-detachment clip 47 to engage with the outer side of the nut 46. To increase the stability of the photovoltaic panel and prevent loosening, a protective unit 2 is installed on the right side of the mounting base 1 via a buffer unit 3. The buffer unit 3 includes a main buffer spring 31, a side frame 32, a placement base 33, a damping rod 34, a locking frame 35, a secondary buffer spring 36, a sliding plate 37, and a support frame 38. The side frame 32 is fixed to the right side of the mounting base 1. Main buffer springs 31 are fixed to both sides inside the side frame 32. The main buffer springs 31 are connected to one end of the left side of the placement base 33. The middle part inside the side frame 32 is connected to one end of the damping rod 34, and the other end of the damping rod 34 is connected to the middle part of the left side of the placement base 33. A support frame 38 is fixed to the bottom of the right side of the placement base 33. The sliding plate 37 is installed on the bottom of the left side of the mounting plate 24. At the end, the slide plate 37 is slidably installed inside the support frame 38. A secondary buffer spring 36 is fixed on the top surface of the slide plate 37, and a locking frame 35 is installed on the top of the secondary buffer spring 36. The locking frame 35 is engaged with the locking groove on the top surface of the support frame 38. The main buffer spring 31, together with the damping rod 34, can buffer lateral impacts, while the locking frame 35 is engaged in the locking groove to install the fixing plate 24. The secondary buffer spring 36 can buffer longitudinal impacts. This multi-directional impact protection structure can effectively protect the edge of the photovoltaic panel. The buffer unit 3 also includes a T-slot 39, a T-block 310, a friction plate 311, a friction block 312, and a limiting plate 313. The T-slot 39 is opened in the middle of the right side of the placement seat 33.T-block 310 is fixed to the top of the left side of the fixing plate 24. Two friction plates 311 are fixed to the right side of the placement base 33, one in front and one behind. Two friction blocks 312 are fixed to the left side of the fixing plate 23, one in front and one behind. The friction blocks 312 are positioned corresponding to the friction plates 311. Two limiting plates 313 are fixed to the middle of the left side of the placement base 33, one in front and one behind. The limiting plates 313 are slidably inserted into the limiting groove on the right side of the side frame 32. T-block 310 slides inside the T-groove 39, and the friction between the friction blocks 312 and the friction plates 311 converts the impact kinetic energy into heat energy, which greatly reduces the impact force.

[0036] Protective Unit 2 includes a bracket 21, a frame 22, bolts 23, a fixing plate 24, a mounting groove 25, a mounting block 26, and a protective plate 27. Two corresponding frames 22 are located on the right side of the fixing plate 24. The bracket 21 is slidably installed inside the two frames 22. Screw holes are provided on both sides of the surface of the fixing plate 24. Bolts 23 pass through the through holes on the surface of the bracket 21 and are threaded into the screw holes on the surface of the fixing plate 24. The mounting block 26 is fixed to the top of the bracket 21. The bottom surface of the protective plate 27 has a mounting groove 25, which slidably engages with the mounting block 26. Protective Unit 2 also includes fixing bolts 28 and a support plate 29. The support plate 29 is fixed to the right side of the bracket 21. The screw holes on the surface of the support plate 29 are threaded with fixing bolts 28. The fixing bolts 28 are inserted into the fixing holes on the bottom surface of the protective plate 27. The protective plate 27 is fixed by inserting the fixing bolts 28 into the fixing holes on the bottom surface of the protective plate 27, which also facilitates subsequent disassembly. The protective unit 2 also includes transparent glass 210 and sponge pad 211. The transparent glass 210 is installed on the top surface of the protective plate 27, and the sponge pad 211 is adhered to the bottom surface of the protective plate 27. The transparent glass 210 does not affect the light transmission of the photovoltaic panel, and can self-clean when it rains to ensure the light efficiency of the area. The sponge pad 211 can play a protective role when the protective plate 27 is attached to the photovoltaic panel.

[0037] The system also includes a frame 5, a connecting plate 6, and a support plate 7. The connecting plate 6 is fixed to the right side of the frame 5, and the surface of the connecting plate 6 has two corresponding through holes. Support plates 7 are fixed to both the front and rear sides of the frame 5. The bracket 21 is installed into the frame 22 using bolts 23. The mounting block 26 is slidably inserted into the mounting groove 25 to install the protective plate 27. The protective plate 27 can prevent damage to the photovoltaic panel from the impact of hail and other objects. The system also includes Velcro 8, Velcro 9, and a rubber pad 10. The Velcro 9 is fixed to the groove on the inner side of the fixing frame 44. The Velcro 8 is fixed to the outer side of the rubber pad 10. The Velcro 8 and the Velcro 9 are bonded together. The Velcro 9 and the Velcro 8 are bonded together to install the rubber pad 10. This increases the friction with the surface of the photovoltaic panel, making the clamping more secure. Due to its softness, it avoids direct contact between metal or hard components. To protect the photovoltaic panel surface from scratches or stress concentration, the system also includes a main protective pad 11 and a secondary protective pad 12. The main protective pad 11 is fixed to the top surface inside the frame 5, and the secondary protective pad 12 is fixed to the bottom surface inside the frame 5. Both the main protective pad 11 and the secondary protective pad 12 are silicone pads. The main protective pad 11 and the secondary protective pad 12 can protect the surface of the photovoltaic panel. The system also includes a pole seat 13 and a fixing rod 14. There are four pole seats 13, which are fixed in pairs to the front and rear sides of the fixing seat 1. The inside of the pole seat 13 is inserted into one end of the fixing rod 14. The fixing rod 14 is inserted into the through hole on the surface of the connecting plate 6. The fixing rod 14 inside the pole seat 13 can connect the fixing seat 1 and the frame 5, so that the entire protective structure forms a complete rigid frame around the edge of the photovoltaic panel, which greatly enhances the overall structural strength and stability and effectively resists torsion and deformation.

[0038] The working principle of the photovoltaic panel edge impact protection structure provided by this invention is as follows: First, the frame 5 is clamped at the connection point of the photovoltaic panel. Rotating the wheel 43 drives the bidirectional screw 41 to rotate, causing two fixing brackets 44 to clamp onto both sides of the photovoltaic panel surface. Rotating the nut 46, in conjunction with the locking screw 45, locks the height of the fixing brackets 44. The spring 39 extends, causing the anti-detachment clip 47 to lock onto the outside of the nut 46. This increases the firmness of the photovoltaic panel fixation, preventing loosening. The Velcro 9 and Velcro 8 are bonded to install the rubber pad 10, along with the main protective pad 11 and secondary protective pad 12. This increases the friction with the photovoltaic panel surface, making the clamping more secure. Due to its softness, it avoids scratches or stress concentration that might occur from direct contact between metal or hard components and the photovoltaic panel surface. Subsequently, the fixing rod 14 inside the rod base 13 connects the fixing base 1 to the frame 5, forming a complete rigid frame around the edge of the photovoltaic panel, greatly enhancing its stability. The overall structural strength and stability effectively resist torsion and deformation. After installation, the bracket 21 is inserted into the frame 22 and installed using bolts 23. The mounting block 26 is slidably inserted into the mounting groove 25 to install the protective plate 27. The fixing bolts 28 are inserted into the fixing holes on the bottom of the protective plate 27 to fix the protective plate 27. In this way, when encountering vertical impact, the secondary buffer spring 36 extends while the T-shaped block 310 slides inside the T-shaped groove 39. At the same time, the friction block 312 and the friction plate 311 rub against each other to convert the impact kinetic energy into heat energy for consumption. This can greatly weaken the impact force and thus buffer and protect against vertical impact. When encountering lateral impact, the main buffer spring 31 works with the damping rod 34 to buffer and protect against lateral impact. This multi-angle impact protection structure effectively protects the edges of the photovoltaic panel from damage caused by hard impact. The transparent glass 210 does not affect the light transmission of the photovoltaic panel and can self-clean when it rains to ensure the light efficiency of the area.

[0039] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
