Description

Technical Field

[0001] This utility model relates to the field of photovoltaic technology, and in particular to a purlin installation device and a photovoltaic tracking bracket. Background Technology

[0002] Related technologies indicate that the design of irregularly shaped main beam cross-section nodes in tracking supports differs from that of square tube cross-sections. Irregularly shaped cross-sections are difficult to fit together, and node contact is prone to slippage. Under wind loads, torque and bending moment are difficult to transmit, leading to node deformation or damage. Purlins, as design nodes connecting the main beam and components, are primarily subjected to compression and uneven torque. The market uses irregularly shaped bolts and purlin connectors to fix the main beam and components in contact. However, the irregularly shaped bolts are difficult to install as they are locked at the top of the components. Summary of the Invention

[0033] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0034] The following is for reference. Figures 1-5 A purlin mounting device 100 according to a first aspect embodiment of the present invention is described.

[0035] like Figure 1 As shown, the purlin installation device 100 according to the first aspect of the present invention includes: a connector 1 and a clamp 2.

[0036] Specifically, the purlin mounting device 100 is used to connect the purlin 3 to the main beam 200 of the photovoltaic tracking bracket. The connector 1 is located on the side of the main beam 200 away from the purlin 3. The clamp 2 is connected between the purlin 3 and the connector 1. The purlin 3, connector 1, and clamp 2 enclose an installation space for installing the main beam 200. It can be understood that the clamp 2, connected between the purlin 3 and connector 1, serves to connect the purlin 3 to the main beam 200. The clamp 2 connects to the connector 1 and cooperates with the purlin 3 to define the installation space. The clamp 2 and connector 1 cooperate to connect the purlin 3 to the main beam 200. (Refer to...) Figure 1 The shape of the installation space is adapted to the cross-sectional shape of the main beam 200, which avoids stress concentration in the main beam 200. The clamp 2 includes two clamps, with one clamp 2 connected to each end of the connector 1. The lower end of the clamp 2 is connected to the connector 1, and the upper end of the clamp 2 is connected to the purlin 3. This ensures the installation stability of the purlin 3 and the main beam 200, making it easier for operators to complete the assembly and replacement work more quickly, thus realizing rapid installation and disassembly, and also facilitating future maintenance and upgrades.

[0037] According to the embodiment of the present utility model, the purlin installation device 100, through the cooperation of the connector 1 and the clamp 2, simplifies the structure of the purlin installation device 100, realizes the rapid installation and replacement between the purlin 3 and the main beam 200, improves work efficiency, reduces time costs, facilitates the maintenance and upgrading of the purlin 3 and / or the main beam 200, and the locking component ensures a stable connection between the purlin 3 and the photovoltaic tracking bracket under various environmental conditions, thereby enhancing the safety and stability of the overall structure.

[0038] In some embodiments of this application, the purlin 3 has a first connecting portion, the connector 1 has a second connecting portion, one end of the clamp 2 has a third connecting portion, and the other end has a fourth connecting portion. One end of the clamp 2 is connected to the purlin 3 through the third connecting portion and the first connecting portion, and the other end of the clamp 2 is connected to the connector 1 through the fourth connecting portion and the second connecting portion. It is understood that the first connecting portion is formed on the purlin 3, the second connecting portion is formed on the connector 1, the third connecting portion is formed at the upper end of the clamp 2, and the fourth connecting portion is formed at the lower end of the clamp 2. The clamp 2 and the purlin 3 cooperate through the first connecting portion and the second connecting portion, and the clamp 2 and the connector 1 cooperate through the second connecting portion and the fourth connecting portion, thereby defining an installation space for installing the main beam 200. The purlin installation device 100 has a simple structure and few parts, simplifying the installation and disassembly process, reducing the time and complexity of manual operation, ensuring a stable connection between the purlin 3 and the photovoltaic tracking bracket, and improving the stability and safety of the overall system.

[0039] In some embodiments of this application, the first connecting part is formed as a connecting hole 31, the third connecting part is formed as a hook 21, one end of the clamp 2 is connected to the purlin 3 through the hook 21 extending into the connecting hole 31, the second connecting part is formed as a groove 11, and the fourth connecting part is formed as a post 22, the other end of the clamp 2 is connected to the connector 1 through the post 22 extending into the groove 11. It can be understood that the connecting hole 31 serves as a fixing point at one end of the clamp 2, facilitating the quick insertion of the hook 21 and reducing the assembly difficulty of the clamp 2 and the purlin 3. The groove 11 serves as a fixing point at the other end of the clamp 2, facilitating the insertion and locking of the post 22, reducing the assembly difficulty of the clamp 2 and the connector 1. Furthermore, the mating structure of the hook 21 and the post 22 effectively prevents loosening, and the mating structure of the clamp 2 and the groove 11 effectively prevents loosening, improving the tensile and torsional resistance of the connection.

[0040] In some embodiments of this application, the locking post 22 extends along the axial direction of the main beam 200, and a connecting segment 23 is connected to each end of the locking post 22. The connecting segments 23 extend radially along the main beam 200, with one end connected to the locking post 22 and the other end connected to the locking hook 21. (Refer to...) Figure 3 As shown, the retaining post 22 is along the axial direction of the main beam 200 (e.g., Figure 3 Extending in the front-to-back direction (as shown), the front end of the retaining post 22 is connected to a connecting segment 23, and the rear end of the retaining post 22 is connected to a connecting segment 23. Both connecting segments 23 extend along the radial direction of the main beam 200 (e.g., as shown in the front-to-back direction). Figure 3 Extending in the vertical direction, the lower end of the connecting section 23 is connected to the locking post 22, and the upper end of the connecting section 23 is connected to the locking hook 21. Furthermore, the shape of the connecting section 23 is adapted to the shape of the outer periphery of the main beam 200, which can better connect and fix the main beam 200 and ensure the connection stability between the purlin 3 and the main beam 200.

[0041] In some embodiments of this application, the purlin 3 includes a first plate 32, a second plate 33, and a third plate 34. The second plate 33 and the third plate 34 are connected to the first plate 32 on both sides of the main beam 200 in the axial direction. Both the second plate 33 and the third plate 34 have connecting holes 31 formed therein, and the connecting holes 31 on the second plate 33 and the connecting holes 31 on the third plate 34 are arranged coaxially. (Refer to...) Figure 4 As shown, the second plate 33 is connected to the front side of the first plate 32, and the third plate 34 is connected to the rear side of the first plate 32. The second plate 33 and the third plate 34 have connecting holes 31, and the corresponding connecting holes 31 are arranged coaxially. This improves the safety and reliability of the connection, increases the bending strength and overall rigidity of the purlin 3, and enhances the overall structure of the purlin 3 and the purlin mounting device 100.

[0042] In some embodiments of this application, both the second plate 33 and the third plate 34 extend in a direction perpendicular to the first plate 32. It is understood that the perpendicular extension of the second plate 33 and the third plate 34 to the first plate 32 effectively increases the moment of inertia of the cross section, enhances the bending resistance of the purlin 3, increases the overall torsional stiffness of the purlin 3, and makes it less prone to twisting. The second plate 33 and the third plate 34 provide lateral support, reducing the risk of instability.

[0043] In some embodiments of this application, the purlin 3 is formed with a first mounting groove 35, the shape of which matches the shape of the main beam 200. This ensures a tight fit between the purlin 3 and the main beam 200, increases the contact area between them, enhances connection stability, and prevents relative displacement between the purlin 3 and the main beam 200, thereby effectively ensuring the stability and safety of the entire structure.

[0044] In some embodiments of this application, a flange 351 is formed on the edge of the first mounting groove 35, and the flange 351 extends along the axial direction of the main beam 200. It is understood that the flange 351 increases the local rigidity of the first mounting groove 35 to prevent deformation, and the flange 351 covers a part of the main beam 200, providing additional support against shear stress, while avoiding stress concentration.

[0045] In some embodiments of this application, the connector 1 includes a first connecting plate 12, a second connecting plate 13, a third connecting plate 14, a fourth connecting plate 15, and a fifth connecting plate 16. The second connecting plate 13 and the third connecting plate 14 are connected to the first connecting plate 12 on both sides of the main beam 200 in the axial direction, and the fourth connecting plate 15 and the fifth connecting plate 16 are connected to the first connecting plate 12 on both sides of the main beam 200 in the radial direction. The slots 11 on the second connecting plate 13 and the slots 11 on the third connecting plate 14 are correspondingly arranged in the axial direction of the main beam 200. (Refer to...) Figure 2 As shown, the second connecting plate 13 is connected to the front side of the first connecting plate 12, and the third connecting plate 14 is connected to the rear side of the first connecting plate 12. The second connecting plate 13 and the third connecting plate 14 have slots 11 formed on them, which are arranged correspondingly in the front-rear direction. The fourth connecting plate 15 is connected to the left side of the first connecting plate 12, and the fifth connecting plate 16 is connected to the right side of the first connecting plate 12. This improves the safety and reliability of the connection, increases the bending strength and overall rigidity of the purlin 3, and enhances the overall structure of the purlin 3 and the purlin mounting device 100.

[0046] In some embodiments of this application, the second connecting plate 13 and the third connecting plate 14 extend in a direction perpendicular to the first connecting plate 12, while the fourth connecting plate 15 and the fifth connecting plate 16 extend obliquely in directions opposite to each other. It is understood that the second connecting plate 13 and the third connecting plate 14 extending perpendicularly to the first connecting plate 12 effectively increases the moment of inertia of the section, enhances the bending resistance of the purlin 3, increases the overall torsional stiffness of the purlin 3, and makes it less prone to twisting. The second connecting plate 13 and the third connecting plate 14 provide lateral support, reducing the risk of instability. The oblique extension of the fourth connecting plate 15 and the fifth connecting plate 16 allows the shape of the contact surface between the connector 1 and the main beam 200 to closely fit the shape of the outer circumference of the main beam 200, increasing the contact area between the connector 1 and the main beam 200, enhancing the stability of the connection, and preventing relative displacement between the connector 1 and the main beam 200, thereby effectively ensuring the stability and safety of the entire structure.

[0047] Reference Figure 2 As shown, the connector 1 has a second mounting groove 17, the shape of which matches the shape of the main beam 200. This ensures a tight fit between the connector 1 and the main beam 200, increases the contact area between them, enhances the stability of the connection, and prevents relative displacement between them, thus effectively ensuring the stability and safety of the entire structure.

[0048] In some embodiments of this application, the clamp 2 includes two clamps, each clamp 2 being connected to one end of the connector 1. (Refer to...) Figure 1 As shown, the installation space is defined by the connector 1, the clamps 2 connected to both ends of the connector 1, and the purlin 3. The shape of the installation space is adapted to the cross-sectional shape of the main beam 200, which avoids stress concentration in the main beam 200. There are two clamps 2, one connected to each end of the connector 1. The lower end of the clamp 2 is connected to the connector 1, and the upper end of the clamp 2 is connected to the purlin 3. This ensures the installation stability of the purlin 3 and the main beam 200, and makes it easier for operators to complete the assembly and replacement work more quickly, thus realizing rapid installation and disassembly, and also facilitating future maintenance and upgrades.
