Description

Technical Field

[0001] This utility model relates to the field of photovoltaic equipment technology, and more specifically, to a photovoltaic rail connection component. Background Technology

[0002] Solar energy, as a clean and renewable energy source, can achieve a sustainable energy supply. Photovoltaic power generation, as one of the main ways to utilize solar energy, is gradually becoming an important force in the global energy transition due to its high efficiency, flexibility and reliability.

[0003] In photovoltaic (PV) power generation systems, precise positioning and installation of PV panels are required to ensure they receive maximum solar radiation. Guide rails, as installation guides, provide accurate installation position and angle adjustments for the PV panels, thereby improving their light-gathering efficiency. Existing technology uses a connecting assembly to securely connect the guide rail to the roof. This assembly includes bolts, nuts, and an L-shaped connector. The connector comprises a first part and a second part connected in an L-shape. Specifically, one bolt passes sequentially through the first part and the roof, while another bolt passes sequentially through the second part and the guide rail, and then a nut is used for fixing, thus achieving the connection between the guide rail and the roof.

[0004] However, since the connector only provides support for the guide rail from the side, it is easy for the guide rail to shift or wobble under the action of external force, thus affecting the stability of the overall structure. Utility Model Content

[0005] The purpose of this invention is to provide a photovoltaic guide rail connection component, which solves the technical problem of how to effectively support the guide rail to improve the stability of the overall structure.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution.

[0007] This utility model provides a photovoltaic guide rail connection assembly, comprising: a connector, including a base and a connecting seat erected on the base, the base being connected to the roof, and the connecting seat abutting against the side of the guide rail; a pressure block, including a connecting portion connected to the connecting seat and a positioning portion disposed above the connecting portion, the positioning portion including a support sub-part and a positioning sub-part, the support sub-part being connected to the connecting portion and the positioning sub-part respectively, and being supported below the guide rail, the positioning sub-part being located in the positioning groove, and the positioning sub-part and the support sub-part forming a limiting fit that restricts the guide rail from disengaging from the support sub-part in the vertical direction, and the positioning sub-part and the connecting seat forming a limiting fit that restricts the guide rail from disengaging from the connecting seat in the horizontal direction.

[0008] In some embodiments of this application, the positioning sub-part includes a first part and a second part connected in an L-shape. The first part is connected to the support sub-part and is used to prevent the guide rail from moving away from the connecting seat in the horizontal direction. The second part is arranged parallel to the support sub-part in the vertical direction and is used to prevent the guide rail from moving away from the support sub-part in the vertical direction.

[0009] In some embodiments of this application, the support sub-part extends to both sides of the positioning sub-part in the horizontal direction and is supported by the guide rail below both sides of the positioning groove.

[0010] In some embodiments of this application, the photovoltaic rail connection assembly further includes an elastic element, which is clamped between the connection portion and the connection seat.

[0011] In some embodiments of this application, the connecting portion includes a first connecting portion and a second connecting portion. The first connecting portion extends along the vertical direction, and its two ends are respectively connected to the bottom end of the support sub-part and one end of the second connecting portion. The first connecting portion clamps the elastic element on the connecting seat. The second connecting portion extends along the horizontal direction, and its other end abuts against the connecting seat.

[0012] In some embodiments of this application, the elastic element is a positioning rubber ring; the first connecting portion is provided with a first connecting hole, and the connecting seat is provided with a second connecting hole; the photovoltaic guide rail connecting assembly further includes a fastener, the fastener including a rod portion and a cap portion, the rod portion passing through the second connecting hole and the elastic element in sequence and locked in the first connecting hole, the cap portion being located on the side of the connecting seat facing away from the elastic element and used to prevent the rod portion from disengaging from the connecting seat on the side of the connecting seat facing the elastic element.

[0013] In some embodiments of this application, both the connecting seat and the guide rail are provided with a wave-like structure, and the wave-like structure on the guide rail and the wave-like structure on the connecting seat are interlocked.

[0014] In some embodiments of this application, the base and the connecting seat are connected in a T-shape.

[0015] As can be seen from the above technical solution, the embodiments of this utility model have at least the following advantages and positive effects:

[0016] In the photovoltaic rail connection assembly of this embodiment, the base of the connector is connected to the roof, ensuring the stability of the connector's position. The connecting part of the pressure block is connected to the connecting seat of the connector, ensuring the stability of the pressure block's position. The support sub-part of the pressure block supports the rail from below, providing upward support for the rail, while the connecting seat provides lateral support for the rail. Due to the blocking effect of the positioning sub-part within the positioning groove, a vertical limiting fit is formed between it and the support sub-part, preventing the rail from detaching upward from the support sub-part under various external forces, ensuring that the rail can be kept in a stable position in the vertical direction. A horizontal limiting fit is formed between the positioning sub-part and the connecting seat, restricting the rail from detaching from the connecting seat from the side away from it, thereby ensuring that the rail can be kept in a stable position in the horizontal direction. Therefore, through the cooperation between the photovoltaic rail connection assembly, the rail, and the roof, a connection relationship can be established between the rail and the roof, enabling the photovoltaic rail connection assembly to perform its connecting function. Furthermore, because the photovoltaic guide rail connection assembly effectively limits and fixes the guide rail in both the vertical and horizontal directions, this fixing method can resist the action of various external forces, prevent the guide rail from shifting or shaking, thereby ensuring the stability of the connection between the guide rail and the roof and improving the stability of the overall structure.

[0033] Please see Figures 1 to 3This utility model provides a photovoltaic guide rail connection assembly for connecting a guide rail 5 and a roof. The guide rail 5 has a positioning groove 51 at its bottom and mainly includes a connector 1 and a pressure block 2. The connector 1 includes a base 11 and a connecting seat 12 erected on the base 11. The base 11 is connected to the roof, and the connecting seat 12 abuts against the side of the guide rail 5. The pressure block 2 includes a connecting portion 21 connected to the connecting seat 12 and a positioning portion 22 located above the connecting portion 21. The positioning portion 22 includes a support sub-portion 221 and a positioning sub-portion 222. The support sub-portion 221 is connected to both the connecting portion 21 and the positioning sub-portion 222 and is supported below the guide rail 5. The positioning sub-portion 222 is located within the positioning groove 51, and a limiting fit is formed between the positioning sub-portion 222 and the support sub-portion 221 to restrict the guide rail 5 from disengaging from the support sub-portion 221 in the vertical direction. A limiting fit is also formed between the positioning sub-portion 222 and the connecting seat 12 to restrict the guide rail 5 from disengaging from the connecting seat 12 in the horizontal direction.

[0034] In the photovoltaic guide rail connection assembly of this embodiment, the base 11 of the connector 1 is connected to the roof, ensuring the stability of the position of the connector 1. The connecting part 21 of the pressure block 2 is connected to the connecting seat 12 of the connector 1, thus ensuring the stability of the position of the pressure block 2. The support sub-part 221 of the pressure block 2 is supported below the guide rail 5, providing upward support for the guide rail 5, while the connecting seat 12 provides lateral support for the guide rail 5. Due to the blocking effect of the positioning sub-part 222 in the positioning groove 51, a vertical limiting fit is formed between it and the support sub-part 221, which can prevent the guide rail 5 from detaching upward from the support sub-part 221 under various external forces, ensuring that the guide rail 5 can be kept in a stable position in the vertical direction. A horizontal limiting fit is formed between the positioning sub-part 222 and the connecting seat 12, which can restrict the guide rail 5 from detaching from the connecting seat 12 from the side away from the connecting seat 12, thereby ensuring that the guide rail 5 can be kept in a stable position in the horizontal direction. Therefore, through the cooperation between the photovoltaic guide rail connecting component, the guide rail 5, and the roof, a connection can be established between the guide rail 5 and the roof, allowing the photovoltaic guide rail connecting component to play its connecting role. Furthermore, because the photovoltaic guide rail connecting component effectively limits and fixes the guide rail 5 in both the vertical and horizontal directions, this fixing method can resist various external forces, preventing the guide rail 5 from shifting or shaking, thereby ensuring the stability of the connection between the guide rail 5 and the roof and improving the overall structural stability.

[0035] Please see Figure 2 and Figure 3In one embodiment, a limiting engagement is formed between the positioning sub-part 222 and the support sub-part 221 to prevent the guide rail 5 from disengaging from the support sub-part 221 in the vertical direction, and a limiting engagement is formed between the positioning sub-part 222 and the connecting seat 12 to prevent the guide rail 5 from disengaging from the connecting seat 12 in the horizontal direction. The positioning sub-part 222 includes a first part 2221 and a second part 2222 connected in an L-shape. The first part 2221 is connected to the support sub-part 221 and prevents the guide rail 5 from moving horizontally away from the connecting seat 12. The second part 2222 is parallel to the support sub-part 221 in the vertical direction and also prevents the guide rail 5 from moving vertically away from the support sub-part 221. The first part 2221 and the second part 2222 of the L-shaped positioning sub-part 222 respectively limit the guide rail 5 in the horizontal and vertical directions, providing a simple and practical structural design for the positioning sub-part 222.

[0036] Please see Figures 1 to 3 In a specific embodiment, the support sub-part 221 extends horizontally to both sides of the positioning sub-part 222 and supports the guide rail 5 below both sides of the positioning groove 51. The support sub-part 221 provides a uniform, upward supporting force to the guide rail 5 from both sides of the positioning groove 51, enabling more stable, uniform, and reliable support for the guide rail 5.

[0037] Please see Figures 1 to 4 In a specific embodiment, the photovoltaic rail connection assembly further includes an elastic element 3, which is clamped between the connecting portion 21 and the connecting seat 12. Because the elastic element 3 possesses elastic force, the elastic potential energy accumulated when it is clamped between the connecting portion 21 and the connecting seat 12 can act as a buffer, reducing the impact of vibration on the connection stability between the connecting portion 21 and the connecting seat 12, thereby improving the overall stability and reliability of the structure.

[0038] Please see Figures 2 to 4In a specific embodiment, the connecting part 21 includes a first connecting part 211 and a second connecting part 212. The first connecting part 211 extends in a vertical direction, and its two ends are respectively connected to the bottom end of the support sub-part 221 and one end of the second connecting part 212. The first connecting part 211 clamps the elastic member 3 on the connecting seat 12. The second connecting part 212 extends in a horizontal direction, and its other end presses against the connecting seat 12. Since one end of the first connecting part 211 is connected to the bottom end of the support sub-part 221, and the first connecting part 211 presses the elastic member 3 onto the connecting seat 12, the elastic potential energy of the elastic member 3 can be better distributed to the support sub-part 221 and the guide rail 5 thereon, further enhancing the stability of the connection. On the other hand, one end of the second connecting part 212 is connected to the other end of the first connecting part 211, and the other end of the second connecting part 212 presses against the connecting seat 12, thereby ensuring the connection stability between the connecting part 21 and the connecting seat 12. Thus, through the cooperation between the first connecting part 211, the second connecting part 212 and the elastic member 3, a stable support structure can be formed, thereby further enhancing the stability of the overall structure.

[0039] In one embodiment where the base 11 is connected to the roof, the elastic element 3 is a positioning rubber ring. The first connecting part 211 has a first connecting hole 2111, and the connecting seat 12 has a second connecting hole 121. The photovoltaic rail connection assembly also includes a fastener 4, which includes a rod 41 and a cap 42. The rod 41 passes through the second connecting hole 121 and the elastic element 3 sequentially and is locked within the first connecting hole 2111. The cap 42 is located on the side of the connecting seat 12 facing away from the elastic element 3 and is used to prevent the rod 41 from detaching from the side of the connecting seat 12 facing the elastic element 3. This method of connecting the connecting seat 12 and the connecting part 21 using the fastener 4 is relatively simple and facilitates installation and disassembly. During installation, simply pass the rod 41 through the second connecting hole 121 and the positioning rubber ring sequentially, and then lock it within the first connecting hole 2111. When disassembly is required, simply loosen the lock between the rod 41 and the first connecting hole 2111 to remove the connecting part 21 from the connecting seat 12. This design facilitates the maintenance and replacement of photovoltaic rail connection components, reducing installation and maintenance costs.

[0040] In this embodiment, the rod 41 is locked in the first connecting hole 2111. This can be because both the rod 41 and the first connecting hole 2111 have threads and are locked together by a threaded connection. Alternatively, the fastener 4 may also include a nut. The rod 41 has an external thread, passes through the first connecting hole 2111, and the external thread is exposed outside the first connecting hole 2111. The rod 41 is threadedly connected to the nut to lock the rod 41 in the first connecting hole 2111.

[0041] Please see Figure 4In this embodiment, the base 11 is provided with a third connecting hole 111, and a fastener 4 is also provided between the base 11 and the roof. For the specific connection method, please refer to the specific connection method between the connecting part 21 and the connecting seat 12 in the above embodiment, which will not be described in detail here.

[0042] Please see Figures 2 to 4 In the specific assembly process, the base 11 of the connector 1 is first fixed to the roof by a fastener 4. Then, the connector 12, the elastic element 3, the connector 21 and another fastener 4 are pre-assembled. Then, the guide rail 5 is placed on the support sub-part 221 of the pressure block 2, and the positioning groove 51 at the bottom of the guide rail 5 is aligned with the positioning sub-part 222 of the pressure block 2. In this pre-installed state, there is still a certain gap between the guide rail 5 and the connector 12 in the horizontal direction, and the support sub-part 221 is not locked for the vertical support of the guide rail 5. Subsequently, the relative positions of the connecting part 21 and the fastener 4 are adjusted, and the connecting part 21, the elastic element 3 and the guide rail 5 are moved as a whole towards the side closer to the connecting seat 12 until the guide rail 5 is pressed onto the connecting seat 12. Finally, the relative positions of the connecting part 21 and the fastener 4 are locked in this position. At this time, the connecting seat 12 can provide lateral support for the guide rail 5, and the guide rail 5 is limited in the vertical direction on the support sub-part 221. This fixing method is fast and safe, and reduces the installation difficulty and cost.

[0043] In a further embodiment, the length of the positioning sub-part 222 in the horizontal direction is less than or equal to the width of the positioning groove 51 in the horizontal direction. During the assembly process, it is only necessary to align the positioning groove 51 of the guide rail 5 and the positioning sub-part 222 vertically to achieve the cooperation between the two, without the need for the guide rail 5 to be pushed in from the horizontal direction and for the positioning groove 51 and the positioning sub-part 222 to cooperate accordingly, thereby further simplifying the assembly method.

[0044] Please see Figures 2 to 5 In a specific embodiment, both the connecting seat 12 and the guide rail 5 are provided with a wave-shaped structure 6, and the wave-shaped structure 6 on the guide rail 5 and the wave-shaped structure 6 on the connecting seat 12 are interlocked. On the one hand, this increases the contact area between the guide rail 5 and the connecting seat 12, thereby enhancing the side support function of the connecting seat 12 on the guide rail 5. On the other hand, it restricts the vertical displacement of the guide rail 5 and the connecting seat 12, further improving the stability of the overall structure.

[0045] In this embodiment, the end of the second connecting part 212 that presses against the connecting seat 12 is also provided with a wave-shaped structure 6 that cooperates with the wave-shaped structure 6 of the connecting seat 12.

[0046] Please see Figures 1 to 4In a specific embodiment, the base 11 and the connecting seat 12 are connected in a T-shape. The T-shaped connection structure can effectively transmit and disperse forces. This structure increases the contact area and support strength of the connecting part 21, thereby improving the load-bearing capacity of the photovoltaic rail connection assembly.

[0047] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
