Commonly used fastening devices on the market are not only cumbersome to install and inefficient, but also pose safety risks due to the excessive tightening of screws at heights, which can lead to worker fatigue.

[0003] Therefore, in response to the above-mentioned technical problems, how to reduce the difficulty of component fastening procedures and improve construction efficiency is a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0004] The purpose of this application is to provide a photovoltaic module fastening device that can effectively solve the pain points of traditional module fastening procedures being cumbersome, having low construction efficiency, and posing safety hazards.

[0027] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] like Figure 1 As shown, in this embodiment, a photovoltaic module fastening device is provided. The device includes a main frame, an adjusting plate 3, and adjusting bolts 4. The main frame serves as the main load-bearing component of the device, and both the adjusting plate 3 and the adjusting bolts 4 are mounted on the main frame. Specifically, the main frame includes a U-shaped frame 1 and clamping plates 2 disposed on two parallel sides 11 of the U-shaped frame 1. The two clamping plates 2 are located on the outer side of the U-shaped frame 1, that is, the clamping plates 2 extend outward toward the parallel sides 11, thereby forming a double-ear structure on both sides of the U-shaped frame 1.

[0029] In addition, the clamping plate 2 extends squarely along its own plate surface, so that the extended part protrudes on the plane where the U-shaped frame 1 is located. That is, the extended part of the clamping plate 2 protrudes from the U-shaped frame 1, so that the protruding part can extend into the component frame 9 and fit with one frame edge 91 of the component frame 9, so as to prevent the component frame 9 from interfering with the U-shaped frame 1.

[0030] Adjustment plate 3 is movably mounted on the connecting edge 12 of the U-shaped frame 1, and is also located inside the U-shaped frame 1. Please refer to [reference needed]. Figure 1 and Figure 2 Since the adjustment plate 3 is movable, the upper space of the adjustment plate 3 will change as it moves, so as to accommodate photovoltaic modules 8 of different specifications. The photovoltaic module 8 usually includes the module frame edge 91, purlins, etc., which are not restricted in detail here.

[0031] The photovoltaic module 8 is placed in the U-shaped space above the adjustment plate 3. The module frame 9, which needs to be fixedly connected to the photovoltaic module 8, is placed above the photovoltaic module 8. At the same time, the clamping plate 2 is attached to one edge 91 of the module frame 9. Thus, under the joint clamping action of the adjustment plate 3 and the clamping plate 2, the U-shaped space between the adjustment plate 3 and the clamping plate 2 forms a clamping space to accommodate the photovoltaic module 8. Then, by adjusting the position of the adjustment plate 3, the photovoltaic module 8 gradually comes into contact with the module frame 9, thereby achieving the clamping of the two.

[0032] The movement of the adjusting plate 3 is achieved by the adjusting bolt 4. Specifically, the adjusting bolt 4 is threadedly connected to the connecting edge 12. Please refer to [reference needed]. Figure 2 The screw end of the adjusting bolt 4 is connected to the adjusting plate 3, so that by turning the adjusting bolt 4, the position of the adjusting plate 3 in the U-shaped frame 1 is changed, thereby pressing the photovoltaic module 8 and the module frame 9 together.

[0033] In summary, the main frame of this application serves as the primary load-bearing structure of the device, supporting the connection of the entire device. Adjusting plates 3 and adjusting bolts 4 are both located on the main frame. Specifically, the U-shaped frame 1 of the main frame can accommodate photovoltaic modules 8, and the clamping plate 2 of the main frame restricts the movement of the module frame 9. Under the action of adjusting bolts 4 and adjusting plates 3, the photovoltaic modules 8 gradually move towards the module frame 9 until they are stably abutted, thus achieving a secure connection. This application reduces the difficulty of the module fastening process, improves the overall construction efficiency, and effectively solves the problem of low efficiency in traditional solar power station construction.

[0034] The main frame can be made of aluminum alloy, which has strong hardness and is relatively lightweight. When installing the main frame, it can be inserted into the photovoltaic module 8 along the U-shaped opening direction.

[0035] As a key component of the main frame and a major stress point, the clamping plate 2 protrudes from the plane of the U-shaped frame 1 and fits against the component frame 9. Protrusions 21 are provided on the mating surface between the clamping plate 2 and the component frame 9. Please refer to [reference needed]. Figure 4 Increase contact friction to prevent slipping; the protrusion 21 can be an inverted cone-shaped protrusion, the cone-shaped design can pierce the surface of the component frame 9 to play the role of static electricity conduction. During installation, the clamping plate 2 needs to be tightly attached to the component frame 9.

[0036] In some embodiments, the contact surface between the pressing plate 2 and the component frame 9 can be set perpendicular to the parallel side 11 of the U-shaped frame 1, and the contact surface between the adjusting plate 3 and the photovoltaic module 8 is parallel to the contact surface between the pressing plate 2 and the component frame 9.

[0037] It should be noted that when the photovoltaic module 8 is a square structure such as a purlin, and the module frame 9, which is fastened to the purlin, is located on one side of the purlin, the two need to maintain a certain degree of parallelism when fastening. Therefore, the contact surface between the adjusting plate 3 and the photovoltaic module 8 can be parallel to the contact surface between the pressing plate 2 and the module frame 9, thereby ensuring that the photovoltaic module 8 and the module frame 9 can be fastened in the form of surface contact, thus improving the fastening effect.

[0038] The design of the adjusting plate 3 serves a fastening function. The tightening force of the adjusting bolt 4 can be transmitted upward to press the purlin, and it can also accommodate errors such as purlin width and verticality of component frame 9.

[0039] Based on the above embodiments, to increase the adaptability length of the device to the photovoltaic module 8, the opposite surfaces of the two parallel sides 11 of the U-shaped frame 1 can be attached to the first and second sides of the photovoltaic module 8, respectively, and the adjusting plate 3 can be attached to the third side of the photovoltaic module 8. Please refer to... Figure 3 This allows the photovoltaic module 8 to have a certain limiting effect on the U-shaped frame 1, preventing shaking during the fastening process and reducing the difficulty of the fastening process of the device.

[0040] Correspondingly, the inner frame surface of one frame edge 91 of component frame 9 is attached to the clamping plate 2, please refer to... Figure 3 The outer frame surface of frame edge 91 is attached to the fourth side of photovoltaic module 8, so that photovoltaic module 8 is fastened to module frame 9 under the joint clamping action of pressure plate 2 and adjustment plate 3.

[0041] In addition, a limiting groove is provided at the end of the adjusting plate 3 to engage with the parallel side 11 of the U-shaped frame 1. Please refer to [reference needed]. Figure 1 The limiting groove is adapted to the outer contour of the parallel side 11, thereby restricting the sliding of the adjustment plate 3 along the parallel side 11. The limiting groove is symmetrically arranged at both ends of the adjustment plate 3, which can make the two ends of the adjustment plate 3 move synchronously, ensuring the synchronicity and stability of the movement of both sides of the photovoltaic module 8.

[0042] The connecting edge 12 of the U-shaped frame 1 is perpendicular to the two parallel edges 11. At the same time, the axis of the adjusting bolt 4 is perpendicular to the connecting edge 12, so that the axis of the adjusting bolt 4 can adjust the plate 3 to be perpendicular. Then, the adjusting bolt 4 drives the adjusting plate 3 to move in a square shape parallel to the parallel edge 11, avoiding interference between the adjusting plate 3 and the parallel edge 11, which would affect the normal movement of the adjusting plate 3.

[0043] A flat washer 7 and a spring washer 6 are fitted onto the adjusting bolt 4. Please refer to [reference needed]. Figure 2 The flat pad 7 and the spring pad 6 are both standard parts, and will not be described in detail here. By adjusting the tightening of the bolt 4, the photovoltaic module 8 and the module frame 9 are fastened together.

[0044] In some embodiments, a threaded cap 5 is fixedly provided on the connecting plate, and a limiting cap 31 is provided on the side of the adjusting plate 3 facing the connecting plate. Please refer to... Figure 2 The adjusting bolt 4 is threadedly connected to the connecting plate via a threaded cap 5. Tightening the adjusting bolt 4 changes its extension length on the connecting plate. The end of the adjusting bolt 4 extends into the limiting cap 31 and is rotatably set with the limiting cap 31. Simultaneously, the limiting cap 31 and the adjusting bolt 4 are axially limited. Therefore, when the adjusting bolt 4 rotates to change its extension length on the connecting plate, the adjusting plate 3, under the action of the limiting cap 31, avoids synchronous rotation with the adjusting bolt 4 or a tendency to rotate. This prevents interference between the adjusting plate 3 and the parallel side 11 of the U-shaped frame 1 caused by rotation, ensuring stable movement of the adjusting plate 3.

[0045] This application presents a highly practical and efficient photovoltaic module fastening device for construction sites. It reduces the difficulty of the module fastening process, improves overall construction efficiency, and effectively solves the problem of inefficiency in traditional solar power plant construction, making it worthy of promotion. Compared to commonly used fastening devices on the market, this application requires only one adjusting bolt for fastening (compared to the common use of four bolts). This solution is simpler in structure, more efficient and convenient to use, and fills a gap in current technology.

[0046] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0047] This document uses specific examples to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core ideas of this application. It should be noted that those skilled in the art can make several improvements and modifications to this application without departing from the principles of this application, and these improvements and modifications also fall within the protection scope of the claims of this application.
