Description

Technical Field

[0001] This invention relates to the field of solar energy technology, and in particular to an installation structure for a lightweight photovoltaic module. Background Technology

[0002] Lightweight photovoltaic modules are photovoltaic products that use lightweight materials to replace traditional glass and aluminum frames, and are often paired with flexible or ultra-thin battery technology. Their core feature is a significant reduction in weight, which reduces the load-bearing requirements of the roof and broadens the application scenarios. They are particularly suitable for industrial and commercial factory roofs with limited load-bearing capacity, old roofs, carports, and even curved buildings. Therefore, an installation structure is needed to install the lightweight photovoltaic modules in the appropriate location so that the lightweight photovoltaic modules can complete the operation of generating solar energy in the appropriate location.

[0003] Currently, the following problems still exist when installing lightweight photovoltaic modules: Existing photovoltaic panel installations mostly use independent clamping blocks and multiple bolts for fixing, which requires high precision from workers and involves a large number of bolts, resulting in slow installation speed. Moreover, traditional clamping block installation mainly relies on the clamping force of bolts to externally press the mounting frame. However, under long-term wind vibration, thermal expansion and contraction loads, the bolts are prone to loosening, leading to a decrease in clamping force and a risk of photovoltaic panels being blown away by strong winds. This external pressing method has problems with the stability and durability of its locking force. At the same time, when splicing multiple photovoltaic panels into an array, it is necessary to ensure the flatness and consistent gaps between adjacent panels. However, the existing installation structure lacks an effective rapid guidance and alignment mechanism, relying entirely on the experience of workers for manual alignment. This makes it difficult to achieve high-precision rapid installation, easily causing uneven photovoltaic arrays, affecting aesthetics, and generating additional structural stress. Summary of the Invention

[0004] In view of the common problems of low installation efficiency, insufficient connection reliability and wind vibration resistance in the installation structure of photovoltaic modules mentioned above or in the prior art, this invention is proposed.

[0005] To solve the above-mentioned technical problems, the present invention provides an installation structure for a lightweight photovoltaic module, which is achieved by the following specific technical means: A lightweight photovoltaic module mounting structure includes a bracket and several mounting frames arranged in a linear array on top of the bracket. A photovoltaic panel is fixedly mounted on the mounting frame. Two semi-circular grooves are symmetrically opened on the left and right ends of the mounting frame and distributed in front and behind. A semi-circular wedge is rotatably mounted in the semi-circular groove. Adjacent mounting frames are assembled into a circular wedge assembly by combining two semi-circular wedges. Rotating the circular wedge assembly fixes the two adjacent mounting frames together. A bolt and nut are installed through the center of the circular wedge assembly. The bolt and nut work together to fix the circular wedge assembly on the bracket for mounting the photovoltaic panel on the bracket. A locking rod is slidably installed through the outer ring wall of the semi-circular wedge. The mounting frame has a locking hole located in the semi-circular groove and corresponding to the locking rod. After the circular wedge assembly rotates, the locking rod slides into the corresponding locking hole to fix the circular wedge assembly again, so as to further combine two adjacent mounting frames.

[0006] Preferably, a semi-cylinder is fixedly installed at the center of the semi-circular wedge, and a No. 1 splicing block is fixedly installed on the side wall of the semi-circular wedge away from the corresponding semi-circular groove. A No. 1 docking hole that mates with the No. 1 splicing block is opened on the adjacent semi-circular wedge.

[0007] Preferably, the semicircular wedge is further provided with a connecting assembly, which includes a hinge frame fixedly installed on the locking rod and located inside the corresponding semicircular wedge. A spring sleeved on the outside of the corresponding locking rod is fixedly installed between the hinge frame and the inner ring wall of the semicircular wedge. A sliding groove is opened through the lower end face of the semicircular wedge, and a connecting rod located at the sliding groove is hinged on the hinge frame by a torsion spring.

[0008] Preferably, the semi-circular wedge is further provided with a mating component that cooperates with the connecting component. The mating component includes a semi-arc clamp hinged to the lower end of the connecting rod by a torsion spring. The inner ring wall of the semi-arc clamp is threaded. A second splicing block is fixedly installed on the side wall of the semi-arc clamp away from the lower end of the connecting rod. A second docking hole that cooperates with the second splicing block is provided on the adjacent semi-arc clamp.

[0009] Preferably, two adjacent semi-cylinders form a cylindrical assembly, and two adjacent semi-arc clamps cooperate with the second splicing block and the second docking hole to form a circular clamp. The circular clamp is coaxial with the cylindrical assembly, and the bolt moves through the cylindrical assembly and engages with the thread inside the circular clamp.

[0010] Preferably, an Ω-shaped clamp is fixedly installed at the upper end of the semi-cylinder, and adjacent Ω-shaped clamps form a clamp assembly for rotating the circular wedge assembly. After the clamp assembly rotates, it abuts against the photovoltaic panel to fix the photovoltaic panel.

[0011] Preferably, a positioning cross block is fixedly installed on the lower end face of the semi-circular wedge, and a limiting component that cooperates with the positioning cross block to position the rotation angle of the circular wedge assembly is provided on the mounting frame.

[0012] Preferably, the limiting component includes a first limiting block fixedly installed on the lower end face of the mounting frame and cooperating with the corresponding positioning cross block, and a second limiting block fixedly installed on the lower end face of the adjacent mounting frame and cooperating with the positioning cross block on the other side.

[0013] Preferably, an arc-shaped positioning block is fixedly installed at the lower end of the mounting frame to limit the movement of the positioning block and position the initial position of the positioning semi-circular wedge. The outer side of the arc-shaped positioning block is covered with rubber.

[0014] Preferably, a positioning sleeve is fixedly installed on the bracket by bolts and nuts, and a semi-circular positioning block located in a semi-circular groove is fixedly installed on the positioning sleeve.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: by combining semi-circular wedges on adjacent mounting frames to form a circular wedge assembly, the adjacent mounting frames can be quickly and accurately aligned, and the relative positions of adjacent mounting frames can be corrected, ensuring the flatness and gap uniformity of the entire photovoltaic panel linear array. This simplifies the cumbersome process of repeatedly adjusting the position and individually tightening multiple bolts in traditional installation, thereby improving installation efficiency, effectively reducing labor and time costs, and reducing potential structural risks caused by uneven installation stress. At the same time, it ensures the stability of the connection points under harsh conditions such as long-term wind vibration and thermal expansion and contraction, making the wind resistance of the installed lightweight photovoltaic modules far exceed that of the traditional single bolt tightening method.

[0027] 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.

[0028] The terms used in this invention, such as "upper," "lower," "left," "right," "middle," and "one," are merely for clarity of description and are not intended to limit the scope of the invention. Any changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention.

[0029] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A lightweight photovoltaic module mounting structure includes a bracket 1 and several mounting frames 2 arranged on the bracket in a linear array. A photovoltaic panel 3 is fixedly mounted on the mounting frame 2. Two semi-circular grooves 4 are symmetrically opened on the left and right ends of the mounting frame 2 and distributed in front and behind. A semi-circular wedge 41 is rotatably mounted in the semi-circular groove 4.

[0030] Adjacent mounting frames 2 are combined with two semi-circular wedges 41 to form a circular wedge assembly. The circular wedge assembly is rotated to fix the two adjacent mounting frames 2. A bolt 7 and a nut 8 are provided through the center of the circular wedge assembly. The bolt 7 and the nut 8 cooperate to fix the circular wedge assembly on the bracket 1 for mounting the photovoltaic panel 3 on the bracket 1.

[0031] A locking rod 42 is slidably installed through the outer ring wall of the semi-circular wedge 41. The mounting frame 2 has a locking hole 21 located in the semi-circular groove 4 and corresponding to the locking rod 42. After the circular wedge assembly is rotated, the locking rod 42 slides into the corresponding locking hole 21 to fix the circular wedge assembly again, so as to further combine the two adjacent mounting frames 2.

[0032] In actual operation, bracket 1 serves as the basic support component of the entire installation structure, used to bear the weight of the photovoltaic modules and fix them in the corresponding positions. Mounting frame 2 serves as the frame structure for fixing photovoltaic panels 3 to form a photovoltaic array. Bolts 7 and nuts 8 are fasteners used to securely fix the circular wedge components to bracket 1.

[0033] When installing the photovoltaic panel 3, the mounting frame 2 after the photovoltaic panel 3 is installed is first placed on the bracket 1. Then, the adjacent mounting frames 2 are brought close together and the two semi-circular wedges 41 set on them are joined together to form a circular wedge assembly. The circular wedge assembly can be rotated manually or with the help of simple tools. When it is rotated to a certain angle, the two adjacent mounting frames 2 are initially fixed together. The bolt 7 and nut 8 are fastened to the bracket 1 through thread engagement, thereby installing the photovoltaic panel 3 on the bracket 1.

[0034] Furthermore, the locking rod 42 is installed in the radial hole of the outer ring wall of the semi-circular wedge 41. When the circular wedge assembly rotates to the preset fixed position, the locking rod 42 slides into the corresponding locking hole 21 to fix the circular wedge assembly again, thereby further fixing the two adjacent mounting frames 2 and enhancing the reliability of the connection.

[0035] This enables rapid docking and fixing of adjacent photovoltaic panels 3, significantly improving installation efficiency. It also provides dual locking, effectively enhancing the stability of the connection and wind resistance, reducing the risk of bolt 7 loosening, and simplifying the alignment process of photovoltaic panels 3. This helps to achieve flat installation of the photovoltaic array and reduces reliance on the precision of worker operations.

[0036] Please see Figure 4 , Figure 6 , Figure 7 and Figure 8 A semi-circular cylinder 411 is fixedly installed at the center of the semi-circular wedge 41. A first splicing block 412 is fixedly installed on the side wall of the semi-circular wedge 41 away from the corresponding semi-circular groove 4. A first docking hole that mates with the first splicing block 412 is opened on the adjacent semi-circular wedge 41.

[0037] Please see Figure 6 and Figure 8 An Ω-shaped clamp 45 is fixedly installed on the upper end of the semi-cylinder 411. Adjacent Ω-shaped clamps 45 form a clamp assembly for rotating the circular wedge assembly. After the clamp assembly rotates, it abuts against the photovoltaic panel 3 to fix the photovoltaic panel 3.

[0038] In practical operation, when assembling two adjacent semicircular wedges 41, the first splicing block 412 on the semicircular wedge 41 cooperates with the first mating hole on the adjacent semicircular wedge 41. When the two semicircular wedges 41 are close together, the first splicing block 412 is inserted into the first mating hole, realizing the precise alignment and initial mechanical interlocking of the two semicircular wedges 41. This solves the problems of difficult alignment and unstable temporary fixation of the semicircular wedges 41 during assembly, and avoids installation deviation. At the same time, the interlocking effect of the first splicing block 412 and the first mating hole provides a more stable initial connection for the circular wedge assembly, enhances the overall structural strength, and improves the reliability and safety of the lightweight photovoltaic module installation structure. The semi-cylinder 411 at the center of the semicircular wedge 41 provides a clear center positioning for the subsequent penetration of the bolt 7.

[0039] The clamp assembly composed of adjacent Ω-shaped clamps 45 provides an easy-to-grip and force-applying rotation point for the installer, enabling the installer to apply rotational torque to the two semi-circular wedges 41 simultaneously, thereby achieving the overall rotation of the circular wedge assembly and ensuring that the circular wedge assembly is in a tight state of contact with the photovoltaic panel 3.

[0040] After the clamp assembly is rotated to a specific angle, the top edge of the Ω-shaped clamp 45 contacts the upper edge of the photovoltaic panel 3 and applies pressure, thereby restricting the relative movement of the photovoltaic panel 3 and keeping it stable on the mounting frame 2. This applies a downward clamping force to the photovoltaic panel 3, preventing it from being lifted by the wind, thereby reducing the complexity of installation and effectively preventing the risk of the photovoltaic panel 3 loosening or being lifted under loads such as wind vibration or thermal expansion and contraction.

[0041] Please see Figure 4 , Figure 7 and Figure 8 A positioning horizontal block 5 is fixedly installed on the lower end face of the semi-circular wedge 41, and a limiting component 51 is provided on the mounting frame 2 to cooperate with the positioning horizontal block 5 to position the rotation angle of the circular wedge assembly.

[0042] Please see Figure 4 The limiting component 51 includes a first limiting block 511 fixedly installed on the lower end face of the mounting frame 2 and cooperating with the corresponding positioning horizontal block 5, and a second limiting block 512 fixedly installed on the lower end face of the adjacent mounting frame 2 and cooperating with the positioning horizontal block 5 on the other side.

[0043] Please see Figure 4 An arc-shaped positioning block 52 is fixedly installed at the lower end of the mounting frame 2 to limit the movement of the positioning block 5 and the initial position of the positioning semi-circular wedge block 41. The outer side of the arc-shaped positioning block 52 is covered with rubber.

[0044] In actual operation, when the circular wedge assembly rotates, its two positioning blocks 5 will simultaneously cooperate with the first limiting block 511 of the mounting frame 2 and the second limiting block 512 of the adjacent mounting frame 2. The first limiting block 511 and the second limiting block 512 constrain the corresponding positioning blocks 5 from both sides, limiting the range of movement and final position of the positioning blocks 5 during rotation. In this way, the positioning blocks 5 serve as reference points when the circular wedge assembly rotates. In cooperation with the limiting component 51, the rotation angle of the circular wedge assembly can be precisely controlled, thereby ensuring the accuracy and stability of the rotation angle positioning of the circular wedge assembly.

[0045] Secondly, the arc-shaped positioning block 52 provides initial position constraints for the positioning horizontal block 5, effectively preventing unnecessary movement or displacement of the semi-circular wedge block 41 during the initial installation. At the same time, the rubber layer covering the outer side of the arc-shaped positioning block 52 not only significantly increases the friction during positioning, effectively preventing accidental sliding of the positioning horizontal block 5, but also provides a buffering effect, thereby simplifying the installation operation, reducing the requirements for the precision of the workers' operation, and thus improving the overall installation efficiency and the flatness of the photovoltaic panel 3 array, avoiding installation errors and potential structural stress problems caused by initial position deviations.

[0046] Please see Figure 4 , Figure 5 , Figure 7 and Figure 8 A connecting component 44 is also provided on the semi-circular wedge 41. The connecting component 44 includes a hinge frame 441 fixedly installed on the locking rod 42 and located in the corresponding semi-circular wedge 41. A spring 442 sleeved on the outside of the corresponding locking rod 42 is fixedly installed between the hinge frame 441 and the inner ring wall of the semi-circular wedge 41. A sliding groove is opened through the lower end face of the semi-circular wedge 41. A connecting rod 443 located in the sliding groove is hinged on the hinge frame 441 by a torsion spring.

[0047] Please see Figure 4 , Figure 5 , Figure 7 and Figure 8 The semi-circular wedge 41 is also provided with a mating component 43 that cooperates with the connecting component 44. The mating component 43 includes a semi-arc clamp 431 that is hinged to the lower end of the connecting rod 443 by a torsion spring. The inner ring wall of the semi-arc clamp 431 is provided with a thread 433. A second splicing block 432 is fixedly installed on the side wall of the semi-arc clamp 431 away from the lower end of the connecting rod 443. A second docking hole that cooperates with the second splicing block 432 is provided on the adjacent semi-arc clamp 431.

[0048] Please see Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8Two adjacent semi-cylinders 411 form a cylindrical assembly. Two adjacent semi-arc clamps 431 are connected to the second splicing block 432 and the second docking hole to form a circular clamp. The circular clamp is coaxial with the cylindrical assembly. The bolt 7 moves through the cylindrical assembly and engages with the thread 433 inside the circular clamp.

[0049] In actual operation, when adjacent semicircular wedges 41 approach each other, the second splicing block 432 on the two semicircular clamps 431 cooperates with the second docking hole to achieve accurate alignment of adjacent semicircular clamps 431, thereby forming a circular clamp. Then, the bolt 7 is inserted into the two semicircular cylinders 411 to form a cylindrical assembly. When the lower end of the bolt 7 reaches the position of the circular clamp, the bolt 7 is rotated to engage with the thread 433 inside the circular clamp, thereby lifting the circular clamp upward.

[0050] With the cooperation of the positioning block 5 and the limiting component 51, the rotation angle of the circular wedge block assembly is positioned so that the locking rod 42 corresponds to the locking hole 21. Thus, when the circular clamp moves upward, the locking rod 42 is pushed into the locking hole 21 through the connecting rods 443 on both sides until the locking rod 42 is fully inserted into the locking hole 21 to lock the circular wedge block assembly.

[0051] During this process, the two torsion springs on the connecting rod 443 enable the semi-arc clamp 431 to have a certain elastic self-adaptive capability, which can automatically adjust its position to adapt to the movement of the connecting rod 443, thereby providing flexible alignment during the splicing process. Furthermore, during disassembly and maintenance, the spring 442 and the two torsion springs can ensure that the locking rod 42 slides out of the locking hole 21 to release the fixation, while ensuring that the semi-arc clamp 431 is reset.

[0052] Then, the bolt 7 can be inserted through the cylindrical assembly and the circular clamp, and then inserted into the bracket 1 and used with the nut 8 to fix the mounting frame 2, thereby completing the installation of the photovoltaic panel 3.

[0053] Thus, by rotating the circular wedge assembly, the radial preload is generated by the cooperation between the curved surface and the semi-circular groove 4, initially tightly combining the two mounting frames 2 together, thereby completing the first stage of radial locking; subsequently, the locking rod 42 slides into the locking hole 21 of the mounting frame 2 after the wedge rotates, effectively preventing the circular wedge assembly from rotating and loosening under vibration load, thereby completing the second stage of anti-rotation locking.

[0054] This dual-protection mechanism, combined with the central bolt 7, ultimately fixes the entire component to the bracket 1, ensuring the extreme stability of the connection point under harsh working conditions such as long-term wind vibration and thermal expansion and contraction. Its wind resistance performance far exceeds that of the traditional single bolt 7 tightening method.

[0055] Please see Figure 9A positioning sleeve 61 is fixedly installed on the bracket 1 by bolts 7 and nuts 8, and a semi-circular positioning block 6 located in the semi-circular groove 4 is fixedly installed on the positioning sleeve 61.

[0056] In specific operations, when installing the mounting frame 2, if there is no mounting frame 2 on the adjacent side of the mounting frame 2, the semi-circular positioning block 6 can be placed in the semi-circular groove 4 on that side of the mounting frame 2. Then, the bolt 7 is inserted into the positioning sleeve 61, and the semi-circular positioning block 6 on that side is fixed by the nut 8, thereby fixing that side of the mounting frame 2 and providing an installation reference surface for the subsequent installation of the mounting frame 2.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
