[0042] According to one specific embodiment provided by the present application, referring to Figure 1 , Figure 2 and Figure 4 , a purlin assembly 100 is disclosed for connecting a photovoltaic assembly 200 and a main shaft 300, so that the photovoltaic assembly 200 can be obliquely arranged on the main shaft 300. The purlin assembly 100 specifically comprises a purlin body 110 and a support 120; the purlin body 110 is in the shape of a U, and an opening 116 is formed on the side facing the main shaft 300, and the purlin body 110 is formed with a first body 111 and a second body 112 on both sides of the opening 116, the first body 111 is used for mounting the photovoltaic assembly 200, and the second body 112 is used for connecting the support 120, and the end of the support 120 away from the purlin body 110 is used for mounting another adjacent photovoltaic assembly 200.

[0043] Among them, the support 120 is arranged at one end of the second body 112 and extends at least to the edge of the first body 111, so as to cover the opening 116 on the purlin body 110, so that the opening 116 of the purlin body 110 is in a closed state, thereby optimizing the wind bearing capacity and structural strength of the purlin body 110, and reducing the risk of the photovoltaic assembly 200 being overturned when the photovoltaic support is subjected to wind force at a lower cost.

[0044] In this embodiment, the support 120 and the purlin body 110 are fastened and connected by fasteners 500 to ensure the connection strength between the support 120 and the purlin body 110. In actual production, the fasteners 500 can be bolts, screws, rivets, etc., which are not described one by one here and are within the protection scope of the present application. Correspondingly, when the photovoltaic assembly 200 is fixed on the support 120 and the purlin body 110, the photovoltaic assembly 200 and the support 120, and the photovoltaic assembly 200 and the purlin body 110 should also be fastened and connected by fasteners 500, wherein, in order to facilitate the staff to carry out daily maintenance and replacement of the purlin assembly 100 and the photovoltaic support, the photovoltaic assembly 200 and the support 120, and the photovoltaic assembly 200 and the purlin body 110 are preferably connected by bolts.

[0045] As an example, the second body 112 is provided with the support 120 at least at two ends in the extending direction of the purlin body 110, so that the support 120 can support the end of the photovoltaic module 200. In this way, the user can realize stable support of the photovoltaic module 200 with a smaller number of supports 120, and the cost is lower. As a preferred embodiment, the number of supports 120 is two, which are respectively arranged at the two ends of the second body 112 in the extending direction of the purlin body 110. On the premise of ensuring the structural strength of the purlin assembly 100 and the stable support of the photovoltaic module 200, the number of parts is reduced as much as possible, the production cost is reduced, and the lightweight production is realized. Of course, in actual production, the number of supports 120 can also be multiple, and the multiple supports 120 are arranged in sequence along the length direction of the purlin body 110. The support strength of the purlin assembly 100 to the photovoltaic module 200 is improved by arranging multiple supports 120.

[0046] In a preferred embodiment, glue is coated between the support 120 and the purlin body 110. The staff can first glue the support 120 and the purlin body 110 together, and then fasten and connect them through the fastener 500. The connection strength is stronger and the stability is higher.

[0047] Further, referring to Figure 1 and Figure 2 , a gasket 130 can also be arranged between the purlin body 110 and the support 120. The gasket 130 is connected with the support 120 and the first body 111 through the fastener 500, so as to reinforce the connection strength between the purlin body 110 and the support 120. Among them, glue is coated between the gasket 130 and the purlin body 110, that is, the staff first fastens and connects the gasket 130 and the support 120 through the fastener 500, then applies glue to glue the gasket 130 and the purlin body 110 together, and finally fastens and connects the support 120, the gasket 130 and the purlin body 110 through the fastener 500 to assemble the complete purlin assembly 100. The stability of the overall structure of the purlin assembly 100 can be further improved, the structure is simple and the strength is high, which is conducive to stably installing the photovoltaic module 200 on the main shaft 300.

[0048] In a specific embodiment, referring to Figures 1 to 3 , the purlin body 110 further includes a third body 113, a fourth body 114 and a fifth body 115. The first body 111, the third body 113, the fourth body 114, the fifth body 115 and the second body 112 are connected in sequence to form a U-shaped structure, and the third body 113, the fourth body 114 and the fifth body 115 jointly form the above-mentioned opening 116. Among them, the purlin body 110 is preferably integrally formed by bending a steel plate, which has a simple structure and is convenient to process, and is conducive to reducing the production cost while ensuring the structural strength.

[0049] Specifically, the second body 112 is horizontally arranged, and the first body 111 is arranged obliquely relative to the second body 112 and away from the main shaft 300, so that the photovoltaic module 200 can be arranged obliquely relative to the main shaft 300. In order to enable the photovoltaic module 200 to be more firmly mounted on the purlin body 110, the third body 113 adjacent to the first body 111 should also have a certain oblique angle, so that the side wall of the photovoltaic module 200 can be supported on the third body 113.

[0050] Preferably, referring to Figure 2 , the third body 113 is provided with a first bending part 1132 protruding away from the fifth body 115. Because the first body 111 and the third body 113 adjacent to the first body 111 need to have a certain oblique angle and be connected with the photovoltaic module 200, the first bending part 1132 protruding outward is arranged on the third body 113 in this embodiment, so as to increase the chamfer bending and strengthen the structural strength of the purlin assembly 100, which is beneficial to the support of the obliquely arranged photovoltaic module 200 and improves the structural stability, and can also reduce the risk of deformation of the purlin body 110 due to wind force, and the structural arrangement is more reasonable and has strong practicality.

In this embodiment, the second connecting part 123 is higher than the first connecting part 122, and the second connecting part 123 is arranged obliquely towards the direction close to the main shaft 300, so that the photovoltaic module 200 can be arranged obliquely relative to the main shaft 300.

[0053] In actual production, the oblique angles of the first body 111 and the second connecting part 123 are consistent, which is beneficial to the photovoltaic module 200 being arranged obliquely on the main shaft 300 at the same angle. Of course, the oblique angles of the first body 111 and the second connecting part 123 can also be different, and the oblique angle of the first body 111 and the oblique angle of the second connecting part 123 can be flexibly set according to actual needs, which is not limited herein and is within the protection scope of the present application.

[0054] Preferably, referring to Figure 3 Both sides of the second main body part 121, the first connecting part 122 and the second connecting part 123 are provided with a second bending part 124 extending towards the direction of the main shaft 300, which enhances the structural strength of the support part 120 and is more conducive to the support part 120 stably supporting the photovoltaic module 200, thereby ensuring the structural strength and stability of the purlin assembly 100 as a whole at a lower cost. Further, the support part 120 is preferably integrally formed by bending a steel plate, which is simple in structure and convenient to process, and is also conducive to realizing lightweight production of the purlin assembly 100.

[0055] In all the above embodiments, the corners of the purlin body 110 and the support part 120 are all transitioned with a circular arc, which can avoid scratching the workers during disassembly and is safer.
