Description

Technical Field

[0001] This invention relates to the field of photovoltaic equipment installation technology, and in particular to a photovoltaic panel installation structure. Background Technology

[0002] Photovoltaic (PV) modules are power generation devices that directly convert solar energy into electrical energy. They have advantages such as high photoelectric conversion efficiency, high reliability, and low cost, and have been widely used in building roofs, photovoltaic power stations, and solar streetlights in recent years.

[0003] The most common photovoltaic (PV) panel installation structure currently includes a fixed support frame with several mounting frames for accommodating the PV panels. These mounting frames are typically rectangular, and the PV panels are embedded within them and initially positioned to the frames using adhesive or pressure strips. Simultaneously, the support frame is also fixed with U-shaped clips or other types of limiting components, through which the mounting frames are connected to the support frame. In existing technologies, the mounting frames are often fixed to the U-shaped clips using through bolts or lateral tightening, i.e., by pressing the sidewalls or bottom edges of the mounting frames against the contact surfaces of the clips with one or more bolts, thereby securing the overall structure.

[0004] However, in the existing workflow, the mounting frame only relies on the point clamping force of the bolts to contact the U-shaped clamp, while the remaining outer surface of the mounting frame is not constrained by any wrapping or circumferential uniform clamping force. Due to machining tolerances, thermal expansion and contraction deformation, and wear after long-term use, both the mounting frame and the U-shaped clamp inevitably have gaps of varying sizes between them. When operators tighten the bolts, these gaps cause slight random displacement of the mounting frame within the U-shaped clamp, resulting in inconsistent tilt angles and planar positions of different mounting frames in the same array. More seriously, because there are no temporary fixtures for precise pre-positioning and clamping of the mounting frame, operators cannot confirm whether the mounting frame is in the accurate posture required by the design before the bolts are fully tightened. Often, angular deviations are discovered after the bolts are tightened, necessitating rework and adjustment. The initial assembly error caused by the lack of clamping and positioning means during installation will be further amplified by external factors such as wind vibration and temperature cycling after the photovoltaic panel is put into use. This will cause the mounting frame to continuously generate fretting wear and impact within the gap, which will not only cause the preset angle of the photovoltaic panel to gradually shift and reduce the power generation efficiency, but also cause stress concentration and fatigue cracks at the contact points between the mounting frame and the clamps, thus shortening the service life of the photovoltaic panel and the entire installation structure.

[0005] Therefore, in response to the problem of reduced performance and lifespan due to the lack of clamping and positioning methods during photovoltaic panel installation, the applicant needs to design a photovoltaic panel installation structure to solve the problem. Summary of the Invention

[0006] This application provides a photovoltaic panel installation structure that solves the problem of reduced performance and service life caused by the lack of clamping and positioning means in the existing photovoltaic panel installation process. The structure includes a support frame with several mounting frames fixedly mounted on it, each mounting frame containing a photovoltaic panel. A U-shaped clamp is also fixedly mounted on the support frame to clamp the mounting frames. A fastening mechanism is provided on the outer side of each mounting frame to push the mounting frames against the U-shaped clamp. The fastening mechanism includes a fixing module that engages with the mounting frames. A flexible strip with a scale is fixedly mounted on the fixing module. A sliding module is provided at the end of the flexible strip away from the fixing module to position the length of the flexible strip. A fastening module that engages with the mounting frames is also provided on the outer side of the flexible strip to rotate and lock the flexible strip.

[0007] Preferably, the fixing module includes a first clip, and a mounting plate fixedly connected to one end of the flexible strip is fixedly disposed on the first clip. The fixed connection between the first clip and the mounting plate can provide a stable installation reference for the flexible strip and ensure that the starting point of the force application of the fastening mechanism is reliably fixed.

[0008] Preferably, a first telescopic rod is fixedly provided on the inner bottom surface of the first clamping member, and a first clamping plate is fixedly provided on the movable end of the first telescopic rod. An extension slide plate is provided on the first clamping plate, and the open end of the extension slide plate faces the mounting frame. By relying on the cooperation between the first telescopic rod and the first clamping plate, mounting frames of different thicknesses can be clamped adaptively, and the contact area can be increased by using the extension slide plate to improve clamping stability.

[0009] Preferably, the outer side of the first telescopic rod is provided with a first spring that is fixedly connected to the inner bottom surface of the first clamping member, and the other end of the first spring is fixedly connected to the bottom surface of the first clamping plate. The elastic pushing action of the first spring ensures that the first clamping plate always maintains the clamping force on the mounting frame, effectively compensating for the gap caused by tolerance or deformation.

[0010] Preferably, the sliding module includes a fixed block that is fixedly connected to the flexible strip, and a connecting post is fixedly provided below the fixed block. A sliding sleeve is fixedly provided at the end of the connecting post away from the fixed block, and the sliding sleeve is slidably disposed with the flexible strip. The combination of the fixed block, the connecting post and the sliding sleeve enables the sliding module to move with the flexible strip and to provide positioning indication of the length of the flexible strip, which is convenient for precise adjustment.

[0011] Preferably, the fastening module includes a second locking member, and the second locking member is provided with a turning groove for guiding the flexible strip to change direction. A locking component is provided above the turning groove, and the locking component cooperates with the turning groove to lock the flexible strip. The turning groove on the second locking member can guide the flexible strip to change direction smoothly, and cooperates with the locking component to achieve immediate locking of the flexible strip and prevent loosening.

[0012] Preferably, the locking assembly includes a locking block corresponding to the steering groove, and a lifting frame is fixedly provided on the top surface of the locking block. A guide groove is slidably provided on one side of the lifting frame, and the guide groove is fixedly connected to the second clamp. The lifting frame drives the locking block to rise and fall along the guide groove, so that the locking block can vertically press the soft strip in the steering groove, thereby achieving reliable and convenient locking.

[0013] Preferably, a sliding rod is fixedly installed below the lifting frame, and a hollow sleeve fixedly connected to the second locking member is slidably installed on the outer side of the sliding rod. A return spring is installed on the outer side of the hollow sleeve, and the two ends of the return spring are fixedly connected to the lifting frame and the second locking member respectively. The return spring pushes the lifting frame, so that it remains in the raised position when there is no external force, thereby driving the locking block to disengage from the steering groove and remain in the unlocked state. When the lifting frame is pressed down, it overcomes the return spring, so that the locking block vertically presses the soft strip in the steering groove along the guide groove.

[0014] Preferably, a second telescopic rod is fixedly provided on the inner bottom surface of the second clamping member, and a second clamping plate is fixedly provided on the movable end of the second telescopic rod. An extension slide plate is provided on the second clamping plate, and the open end of the extension slide plate faces the mounting frame. A second spring is provided on the outer side of the second telescopic rod and is fixedly connected to the inner bottom surface of the second clamping member. The other end of the second spring is fixedly connected to the bottom surface of the second clamping plate. The synergistic effect of the second telescopic rod, the second clamping plate, and the second spring enables the fastening module to simultaneously clamp the mounting frame and apply a steering force, further enhancing the overall clamping effect.

[0015] Preferably, the support frame has an upper sliding groove and a lower sliding groove on its inner side. The U-shaped clip has a positioning pin threaded on its inner side, and the positioning pin is threadedly connected to the U-shaped clip and extends into the upper sliding groove. A bolt is slidably arranged on the inner side of the lower sliding groove, and a locking nut is threaded on the end of the bolt. The locking nut cooperates with the bolt to fix it to an external fixed object. The upper sliding groove, lower sliding groove, positioning pin, bolt, and locking nut enable the support frame to flexibly adjust its installation position and be firmly connected to an external fixed object, thereby improving the adaptability of the overall structure.

[0016] The photovoltaic panel mounting structure provided in this embodiment of the invention, compared with the prior art:

[0017] This photovoltaic panel mounting structure uses fixing and fastening modules to clamp onto both sides of the mounting frame. The tension of flexible strips applies a wrapping force to the mounting frame, precisely pulling it towards the predetermined contact surface within the U-shaped clamps. This effectively eliminates gaps caused by machining tolerances, thermal expansion and contraction, and wear. Before the bolts are finally tightened, this fastening mechanism acts as a temporary clamp, ensuring the mounting frame maintains accurate tilt angle and planar position, avoiding random displacement and rework adjustments caused by point-like bolt tightening forces. This eliminates initial assembly errors and prevents fretting wear and impacts caused by external factors such as wind vibration and temperature cycling, reducing the risk of stress concentration and fatigue cracks. Ultimately, this improves the photovoltaic panel's power generation efficiency and extends the service life of the entire mounting structure. Attached Figure Description

[0028] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0029] Please refer to Figures 1-7 This invention provides a photovoltaic panel mounting structure, including a support frame 1. A plurality of mounting frames 11 are fixedly mounted on the support frame 1, and photovoltaic panels are respectively mounted within each of the mounting frames 11. A U-shaped clamp 13 is also fixedly mounted on the support frame 1, the U-shaped clamp 13 being used to clamp the plurality of mounting frames 11.

[0030] Several mounting frames 11 are provided with fastening mechanisms 2 on their outer sides, and the fastening mechanisms 2 are used to push the mounting frames 11 to fit tightly against the U-shaped clips 13. The fastening mechanism 2 includes a fixing module 21 that engages with the mounting frame 11. A flexible strip 22 is fixedly mounted on the fixing module 21, and a scale 25 is provided on the flexible strip 22. A sliding module 23 is provided at the end of the flexible strip 22 away from the fixing module 21, and the sliding module 23 is used to position the length of the flexible strip 22. A fastening module 24 that engages with the mounting frame 11 is also provided on the outer side of the flexible strip 22, and the fastening module 24 is used to rotate the flexible strip 22 and lock the flexible strip 22.

[0031] The fixing module 21 serves as the starting point for applying force and is snapped onto one side of the mounting frame 11. The flexible strip 22 extends from the fixing module 21 and extends along the outer contour of the mounting frame 11. The sliding module 23 can slide along the flexible strip 22 to determine the required length of the flexible strip 22. The fastening module 24 is snapped onto the other side of the mounting frame 11, causing the flexible strip 22 to turn and lock at the fastening module 24. By adjusting the effective length and tension of the flexible strip 22, the mounting frame 11 can be pulled tight and pressed against the predetermined contact surface within the U-shaped clamp 13, thereby achieving precise pre-positioning and clamping.

[0032] The fixing module 21 includes a first clip 211, and a mounting plate 212 fixedly connected to one end of the flexible strip 22 is fixedly disposed on the first clip 211. In this embodiment, the first clip 211 is generally U-shaped and is used to clip onto one side edge of the mounting frame 11. The mounting plate 212 is fixedly disposed on the outer side wall of the first clip 211, and one end of the flexible strip 22 is fixed to the mounting plate 212 by riveting.

[0033] Furthermore, a first telescopic rod 213 is fixedly mounted on the inner bottom surface of the first clamping member 211, and a first clamping plate 214 is fixedly mounted on the movable end of the first telescopic rod 213. An extension slide plate is mounted on the first clamping plate 214, with its open end facing the mounting frame 11. Specifically, the first telescopic rod 213 can be a sleeve-type telescopic rod or a gas spring telescopic rod, with its fixed end fixed to the inner bottom surface of the first clamping member 211 and its movable end fixedly connected to the first clamping plate 214. In use, the first clamping member 211 is fastened to the edge of the mounting frame 11, and the first clamping plate 214 is pressed against the surface of the mounting frame 11 under the push of the first telescopic rod 213. The extension slide plate can extend outward according to the actual width of the mounting frame 11 to increase the clamping coverage area. Relying on the cooperation between the first telescopic rod 213 and the first clamping plate 214, mounting frames 11 of different thicknesses can be adaptively clamped, and the extension slide plate increases the contact area, improving clamping stability.

[0034] Furthermore, a first spring 215 is provided on the outer side of the first telescopic rod 213 and is fixedly connected to the inner bottom surface of the first clamping member 211, and the other end of the first spring 215 is fixedly connected to the bottom surface of the first clamping plate 214. In this embodiment, the first spring 215 is a compression spring and is sleeved on the outer periphery of the first telescopic rod 213. When the first clamping plate 214 is subjected to the reaction force of the mounting frame 11, the first spring 215 is further compressed, and the elastic restoring force generated therefrom continuously presses the first clamping plate 214 against the mounting frame 11, effectively preventing the fixing module 21 from loosening.

[0035] The sliding module 23 includes a fixing block 231 fixedly connected to the flexible strip 22, and a connecting post 232 fixedly disposed below the fixing block 231. A sliding sleeve 233 is fixedly disposed at the end of the connecting post 232 away from the fixing block 231, and the sliding sleeve 233 is slidably disposed with the flexible strip 22. Specifically, the fixing block 231 is fixed to the end of the flexible strip 22, and the connecting post 232 extends downward from the fixing block 231, with its lower end connected to the sliding sleeve 233. The sliding sleeve 233 is annular, with a gap fitting around the outer periphery of the flexible strip 22, allowing the sliding sleeve 233 to slide freely along the length direction of the flexible strip 22.

[0036] In use, the sliding sleeve 233 can be manually pushed to slide along the flexible strip 22, and the scale value of the position of the sliding sleeve 233 can be read with the help of the scale 25 on the flexible strip 22, thereby determining the effective length of the flexible strip 22. Through the combination of the fixing block 231, the connecting post 232 and the sliding sleeve 233, the sliding module 23 can not only move with the flexible strip 22, but also provide positioning indication of the length of the flexible strip 22, which facilitates precise adjustment of the tension of the flexible strip 22 and ensures that the tilt angle and planar position of each mounting frame 11 in the same array are consistent.

[0037] The fastening module 24 includes a second locking member 241, which has a steering groove 242 for guiding the flexible strip 22 to change direction. A locking component is positioned above the steering groove 242, and the locking component cooperates with the steering groove 242 to lock the flexible strip 22. The structure of the second locking member 241 is similar to that of the first locking member 211, and it is generally U-shaped, used to engage with the other edge of the mounting frame 11. The steering groove 242 is formed on the upper surface of the second locking member 241 and is an arc-shaped groove. After the flexible strip 22 passes through the steering groove 242, its extension direction changes from horizontal to reverse. Through the steering groove 242 on the second locking member 241, the flexible strip 22 can be guided to smoothly change direction, and the locking component can instantly lock the flexible strip 22 to prevent it from loosening.

[0038] Specifically, the locking assembly includes a locking block 247 corresponding to the turning groove 242, and a lifting frame 243 is fixedly mounted on the top surface of the locking block 247. A guide groove 248 is slidably mounted on one side of the lifting frame 243, and the guide groove 248 is fixedly connected to the second locking member 241. In this embodiment, the guide groove 248 is a vertical slide rail fixed to the side wall of the second locking member 241. The locking block 247 is located directly above the turning groove 242, and its bottom surface is provided with a pressing surface that matches the turning groove 242. In use, pressing down on the lifting frame 243 causes the lifting frame 243 to slide vertically down along the guide groove 248, driving the locking block 247 into the turning groove 242, pressing and fixing the soft strip 22 passing through the turning groove 242. By driving the locking block 247 to rise and fall along the guide groove 248 through the lifting frame 243, the locking block 247 can vertically press the soft strip 22 in the turning groove 242, achieving reliable and convenient locking.

[0039] Furthermore, a sliding rod 245 is fixedly installed below the lifting frame 243, and a hollow sleeve 244, which is fixedly connected to the second locking member 241, is slidably installed on the outer side of the sliding rod 245. A return spring 246 is installed on the outer side of the hollow sleeve 244, and the two ends of the return spring 246 are fixedly connected to the lifting frame 243 and the second locking member 241, respectively. In this embodiment, the sliding rod 245 is vertically fixed to the bottom surface of the lifting frame 243, inserted downward into the hollow sleeve 244, and the sliding rod 245 can slide freely within the hollow sleeve 244. The return spring 246 is a compression spring, sleeved on the outer periphery of the hollow sleeve 244, with its top end abutting against the bottom surface of the lifting frame 243 and its bottom end abutting against the upper surface of the second locking member 241. When the lifting frame 243 is pressed down, the return spring 246 is compressed. When the locking block 247 is pulled out, the lifting frame 243 automatically remains in the unlocked position without external force and will not insert into the guide groove 248.

[0040] Furthermore, a second telescopic rod 249 is fixedly mounted on the inner bottom surface of the second clamping member 241, and a second clamping plate 2491 is fixedly mounted on the movable end of the second telescopic rod 249. An extension slide plate is mounted on the second clamping plate 2491, with its open end facing the mounting frame 11. A second spring 2492 is fixedly connected to the inner bottom surface of the second clamping member 241 on the outer side of the second telescopic rod 249, and the other end of the second spring 2492 is fixedly connected to the bottom surface of the second clamping plate 2491. The structure, connection relationship, and working principle of the second telescopic rod 249, the second clamping plate 2491, and the second spring 2492 are the same as those of the first telescopic rod 213, the first clamping plate 214, and the first spring 215, and will not be described again here. Through the synergistic action of the second telescopic rod 249, the second clamping plate 2491, and the second spring 2492, the fastening module 24 can simultaneously clamp the mounting frame 11 and apply a steering force, further enhancing the overall clamping effect.

[0041] The support frame 1 has an upper sliding groove and a lower sliding groove on its inner side. A positioning pin 12 is threaded onto the inner side of the U-shaped clip 13, and the positioning pin 12 is threadedly connected to the U-shaped clip 13 and extends into the upper sliding groove. A bolt 14 is slidably disposed on the inner side of the lower sliding groove, and a locking nut 15 is threaded onto the screw end of the bolt 14. The locking nut 15 cooperates with the bolt 14 for fixed connection with an external object. Specifically, the upper sliding groove is located on the upper inner side of the support frame 1. A threaded hole is formed on the bottom wall of the U-shaped clip 13, through which the positioning pin 12 passes and extends into the upper sliding groove. By tightening the positioning pin 12, the front-to-back position of the U-shaped clip 13 on the support frame 1 can be finely adjusted and locked. The lower sliding groove is located on the lower inner side of the support frame 1. The head of the bolt 14 is slidably disposed in the lower sliding groove, and the screw portion extends out of the lower sliding groove. The locking nut 15 is screwed onto the screw. During installation, slide the bolt 14 along the sliding groove until it aligns with the mounting hole on the external fixed object, then pass the screw through the mounting hole on the external fixed object and tighten the locking nut 15 to securely fix the support frame 1 to the external fixed object.

[0042] In practical use, the fixing module 21 and the fastening module 24 are respectively snapped onto the two sides of the mounting frame 11. The flexible strip 22 extends from the fixing module 21 and passes through the turning groove 242 of the fastening module 24. The effective length of the flexible strip 22 is precisely adjusted by the sliding module 23 in conjunction with the scale 25 on the flexible strip 22 and a predetermined tension is applied. This tension is transmitted along the flexible strip 22, generating a wrapping pull on the mounting frame 11 that moves towards the predetermined contact surface of the U-shaped clamp 13, thereby eliminating gaps caused by tolerances and deformation. After the mounting frame 11 is adjusted to the correct position, the lifting frame 243 is pressed down to make the locking block 247 press the flexible strip 22 in the turning groove 242 to achieve immediate locking, ensuring that the mounting frame 11 maintains a precise pre-position and clamping state before the subsequent bolts 14 are permanently locked. Finally, the fastening mechanism 2 can be disassembled for reuse. The whole process achieves efficient and precise installation positioning.

[0043] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
