Description

Technical Field

[0001] This utility model relates to the field of photovoltaic technology, and in particular to a flexible assembly photovoltaic module with a limiting structure. Background Technology

[0002] In distributed photovoltaic (PV) or large-scale ground-mounted PV power station systems, PV modules are typically installed using metal brackets attached to the module frame. This method requires evenly distributed bolts on the module frame for multi-point fixation on the metal bracket, resulting in numerous components and a cumbersome installation process. To address this, PV modules assembled using flexible ropes have emerged on the market. For example, Chinese invention publication CN113612430B discloses an integrated device for PV modules and flexible ropes in a solar PV power station. The PV module specifically includes a support shell, rope channels, and other components, which are connected to the flexible ropes via the rope channels. Positioning is achieved through this integrated connection. However, because the rope channels and flexible ropes are integrated, they are difficult to separate and maintain individually. Furthermore, the lack of lateral restraint means allows the support shell to sway along with the flexible ropes in harsh environments such as wind and rain. Lateral displacement during this swaying can easily cause the PV module to collide and be impacted, resulting in poor reliability. Utility Model Content

[0003] The purpose of this invention is to provide a flexible photovoltaic module with a limiting structure. This invention allows for quick assembly and disassembly on a flexible rope, while also providing a reliable limiting effect, making it highly practical.

[0004] The technical solution of this utility model is as follows: A flexible photovoltaic module with a limiting structure is mounted on two flexible ropes on the upper and lower sides of a fixed frame. The flexible photovoltaic module includes a substrate, with crystalline silicon solar cells on the front side of the substrate and a hook plate on the top of the back side of the substrate. The hook plate and the back side of the substrate form a downward-opening engagement groove. A connecting protrusion is provided at the bottom of the back side of the substrate, and a transverse groove is provided on the connecting protrusion to fit with the lower flexible rope. Both ends of the connecting protrusion are provided with transversely inserted C-shaped limiting members. The inner wall of the C-shaped limiting member and the transverse groove form a limiting cavity to fit with the lower flexible rope. The outer end of the C-shaped limiting member is inclined outward and provided with multiple elastic anti-slip members for pressing and adhering with the lower flexible rope.

[0005] In the aforementioned flexible assembly photovoltaic module with a limiting structure, the upper and lower edges of both ends of the connecting protrusion are provided with inserts, and the inner wall of the C-shaped limiting member is provided with a transverse slot that matches the insert.

[0006] In the aforementioned flexible assembly photovoltaic module with a limiting structure, a mounting hole is provided on the groove surface at the inner end of the transverse slot, and a stop block with elastic movable connection is provided in the mounting hole, with the outer side of the stop block corresponding to the inner end face of the insert.

[0007] In the aforementioned flexible assembly photovoltaic module with a limiting structure, the inner side of the block is an inclined surface, and the outer side of the block is a flat surface.

[0008] In the aforementioned flexible assembly photovoltaic module with a limiting structure, the outer end of the insert has a chamfer.

[0009] In the aforementioned flexible assembly photovoltaic module with a limiting structure, the elastic anti-slip member is disposed on one side of the back of the C-shaped limiting member and is inclined outward, with the end of the elastic anti-slip member corresponding to the opening position of the C-shaped limiting member.

[0010] In the aforementioned flexible assembly photovoltaic module with a limiting structure, the transverse groove is provided with a connected expansion opening, the width of which is greater than the diameter of the flexible rope below.

[0011] Compared with existing technologies, this invention, during installation, firstly, the upper flexible rope is inserted into the locking groove, at which point the substrate is initially suspended on the upper flexible rope. Then, the substrate is rotated to embed the lower flexible rope into the transverse groove of the connecting protrusion, completing the longitudinal limitation. The C-shaped limiting piece is inserted into the connecting protrusion from the side, and the limiting cavity enclosed by the transverse groove wraps around the lower flexible rope, completing the fixation. After the C-shaped limiting piece is installed, the elastic anti-slip piece and the lower flexible rope are compressed and bent. When lateral movement occurs, the friction between the elastic anti-slip piece and the flexible rope further bends it. After bending, the contact area increases, further increasing the friction between them to resist lateral movement. The elastic anti-slip pieces on both sides work together to achieve reliable lateral fixation. When maintaining the photovoltaic module, the elastic anti-slip piece is pried off from the lower elastic rope, then the C-shaped limiting piece is pulled out. After rotating the substrate, it is pushed upwards to separate it from both the lower and upper elastic ropes, completing disassembly and facilitating maintenance. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0019] Example: A flexible photovoltaic module with a limiting structure, as shown in the attached figure. Figure 1 As shown, the flexible photovoltaic module is mounted on two flexible ropes, one above the other, with both ends of the ropes fixedly connected to the frame. The flexible assembly photovoltaic module includes a substrate 1, with crystalline silicon solar cells 2 mounted on the front side of the substrate 1, as shown in the attached diagram. Figure 2 - Appendix Figure 4 As shown, an L-shaped hook plate 3 is integrally formed on the top back of the substrate 1, and the hook plate 3 and the back of the substrate 1 form a downward-opening engaging groove 4; a connecting protrusion 5 is integrally formed on the bottom back of the substrate 1, and a transverse groove 6 is formed on the connecting protrusion 5 to fit with the lower flexible rope; C-shaped limiting members 7 are horizontally inserted at both ends of the connecting protrusion 5, and the inner wall of the C-shaped limiting member 7 and the transverse groove form a limiting cavity 8 to fit with the lower flexible rope; two elastic anti-slip members are provided on the outer end of the C-shaped limiting member by adhesive, which are inclined outward for pressing and adhering with the lower flexible rope. The elastic anti-slip members are made of rubber material with a high coefficient of friction; inserts 9 are integrally formed on the upper and lower edges of both ends of the connecting protrusion 5, and transverse slots 10 adapted to the inserts 9 are formed on the inner wall of the C-shaped limiting member 7. The insertion and the transverse slots cooperate to achieve insertion and limiting; as shown in the attached figure. Figure 5As shown, a mounting hole 11 is formed on the inner surface of the transverse slot 10. A stop block 12 is elastically connected to the mounting hole 11 via a spring. The outer side of the stop block 12 corresponds to the inner end face of the insert 9. When inserted, the stop block is pressed into the mounting hole. After insertion, the stop block is elastically pushed out and fits against the insert. The two stop blocks cooperate to strengthen the connection stability between the C-shaped limiting member and the connecting protrusion. The inner side of the stop block 12 is a bevel, and the outer side of the stop block 12 is a flat surface. When inserted, the insert squeezes the bevel to press the stop block into the mounting hole. The outer end of the insert 9 is chamfered to increase the width of the insertion side and enhance the C-shaped limiting. The elastic anti-slip component 16 is bonded to one side of the back of the C-shaped limiting component 7. The end of the elastic anti-slip component 16 corresponds to the opening position of the C-shaped limiting component 7. During the installation process of the C-shaped limiting component approaching the flexible rope, the elastic anti-slip component and the flexible rope are simultaneously pressed together. Then, the C-shaped limiting component is inserted. During the insertion process, the elastic anti-slip component will not bend further, so the friction remains constant, which facilitates installation. The transverse groove 6 has a connected expansion opening 13. The width of the expansion opening 13 is larger than the diameter of the flexible rope below, which facilitates the insertion of the flexible rope and improves the speed of installation.

[0020] Working principle: When installing this flexible photovoltaic module, the first step is to connect it to the upper flexible rope 15. The upper flexible rope 15 is inserted into the engagement groove 4 formed by the hook plate 3 and the back of the substrate 1. At this time, the substrate 1 is initially suspended on the upper flexible rope 15 by the hook plate 3, completing the first step of longitudinal positioning of the module installation. Then, the substrate 1 is rotated to embed the lower flexible rope 15 into the transverse groove 6 on the connecting protrusion 5. This step further determines the position of the module in the longitudinal direction, preventing it from moving up and down, and achieving longitudinal positioning. Subsequently, the C-shaped limiting piece 7 is inserted from the side of the connecting protrusion 5. The inserts 9 at both ends of the connecting protrusion 5 will be inserted into the transverse slots 10 on the inner wall of the C-shaped limiting piece 7. During the insertion process, the chamfer on the outer end of the insert 9 makes the insertion operation smoother. When the insert 9 is inserted, it will squeeze the stop block 12. Since the inner side of the stop block 12 is inclined, the squeezing of the insert 9 will press the stop block 12 into the mounting hole 11. When the insert 9 is fully inserted, the stop block 12 pops out under the action of the spring, and its outer side abuts against the inner end face of the insert 9. The two stop blocks 12 work together to strengthen the connection stability between the C-shaped limiting member 7 and the connecting protrusion 5. After the C-shaped limiting member 7 is inserted into place, the limiting cavity 8 formed by its inner wall and the transverse groove 6 wraps around the lower flexible rope 15, thus fixing the lower flexible rope 15. At the same time, the elastic anti-slip member 16, which is inclined outward at the outer end of the C-shaped limiting member 7, forms a compression and bend with the lower flexible rope 15 after installation. Since the elastic anti-slip member 16 is made of rubber material with a high coefficient of friction, this compression contact can generate a large friction force. During the installation process, the elastic anti-slip member 16 completes the contact and compression with the flexible rope 15 simultaneously when the C-shaped limiting member 7 approaches the flexible rope 15, and then the C-shaped limiting member 7 is inserted. In this way, the elastic anti-slip member 16 will not bend further during the insertion process, the friction force remains constant, and the installation operation is convenient.

[0021] During normal operation of the module, when encountering severe weather such as wind and rain, and the module tends to move laterally, due to the compressive friction between the elastic anti-slip element 16 and the flexible rope 15, when the module is subjected to lateral force, the friction between the elastic anti-slip element 16 and the flexible rope 15 will cause the elastic anti-slip element 16 to bend further. This bending will increase the contact area between the elastic anti-slip element 16 and the flexible rope 15. The increased contact area will further increase the friction between the two, thereby effectively blocking the lateral movement of the module. The elastic anti-slip elements 16 on both sides cooperate with each other to apply resistance to the module from both sides, achieving reliable lateral fixation, ensuring that the photovoltaic module can work stably in harsh environments, reducing collisions and impacts caused by shaking and lateral displacement, and improving the reliability of the module.

[0022] When maintenance of the photovoltaic module is required, firstly, the elastic anti-slip member 16 is pried off to separate it from the lower flexible rope 15, eliminating the squeezing friction of the elastic anti-slip member 16 on the flexible rope 15. Then, the C-shaped limiting member 7 is pulled out from the connecting protrusion 5. At this time, the insert 9 is separated from the transverse slot 10, and the stop block 12 will also return to the mounting hole 11 under the action of the spring. Next, the base plate 1 is rotated to disengage the lower flexible rope 15 from the transverse groove 6. Then, the base plate 1 is pushed upward to disengage the upper flexible rope 15 from the locking groove 4. This completes the entire disassembly process of the module, which facilitates individual maintenance and repair of the module, demonstrating the convenience and practicality of this utility model in practical applications.
