[0032] The integration of BIPV (Building Integrated Photovoltaic) and the outdoor all-weather use environment, the ease of installation and the reliability of long-term use are two key factors of BIPV color steel tile. However, the traditional color steel tile installation needs to be punched, which makes the steps cumbersome, and at the same time, additional drainage components are needed to avoid the problem of rusting of the color steel tile, which has been an urgent industry problem to be solved.

[0033] To solve the above problems, with reference to Figures 1-5 , Figure 1 A structure diagram of a photovoltaic system provided by an embodiment of the present application is shown, Figure 2 A structure diagram of a connecting assembly and a purlin provided by an embodiment of the present application is shown, Figure 3 A structure diagram of a purlin provided by an embodiment of the present application is shown, Figure 2 An enlarged view of part A shown in the figure, Figure 4 A structure diagram of a purlin provided by an embodiment of the present application is shown, Figure 5 An enlarged view of part B shown in the figure. Figure 2 An enlarged view of part B shown in the figure.

[0034] The present application provides a color steel tile 1 for connecting a photovoltaic assembly 2 and a purlin 3, the color steel tile 1 comprising a panel body 11 and a locking edge 12 connected with the panel body 11, the locking edge 12 protruding from one side of the panel body 11 and used for connecting with the photovoltaic assembly 2, the panel body 11 being recessed away from the locking edge 12 to form a first recessed part 111, the first recessed part 111 being recessed away from the locking edge 12 to form a second recessed part 112, the second recessed part 112 having a connecting part 1121, the connecting part 1121 being arranged apart from the first recessed part 111 to form a mounting space 13, and the purlin 3 being sleeved on the second recessed part 112 and extending into the mounting space 13 to be connected with the color steel tile 1.

[0035] It needs to be understood that the color steel tile 1 is made of metal material, and can be made of color steel or other materials, which is not limited by the present application. The color steel tile 1 comprises the panel body 11 and the locking edge 12, the panel body 11 is connected with the locking edge 12, the material of the panel body 11 is the same as that of the locking edge 12, and the panel body 11 and the locking edge 12 are integrally formed. The locking edge 12 protrudes from the surface of the panel body 11, and is used for connecting with the photovoltaic assembly 2, so that the photovoltaic assembly 2 and the panel body 11 are arranged apart from each other, thereby facilitating heat dissipation and reducing the temperature of the photovoltaic assembly 2 and the color steel tile 1.

[0036] The panel body 11 of the color steel tile 1 is recessed in the direction away from the locking edge 12 and recessed to form the first recessed part 111, thereby forming a groove, and the first recessed part 111 extends along the width direction of the panel body 11. The bottom wall of the first recessed part 111 is further recessed in the direction away from the locking edge 12 and recessed to form the second recessed part 112, thereby forming a groove. When it rains, the rainwater can flow from the panel body 11 to the groove of the first recessed part 111, then flow into the groove of the second recessed part 112, and finally flow out from the end of the groove of the second recessed part 112, thereby avoiding the accumulation of rainwater on the panel body 11 and improving the drainage effect of the present application.

[0037] The second recess 112 has a connecting portion 1121 which is arranged in parallel with the panel body 11 and is arranged in a spaced manner with the bottom wall of the first recess 111, so that the mounting space 13 is formed between the bottom wall of the first recess 111 and the connecting portion 1121. The purlin 3 is arranged in a tubular shape and is provided with a mounting opening 31 which extends along the length direction of the purlin 3. The second recess 112 is used to connect with the purlin 3. When connected, the purlin 3 is sleeved on the second recess 112, the mounting opening 31 of the purlin 3 extends into the mounting space 13, the purlin 3 abuts against the connecting portion 1121, the connecting portion 1121 supports the purlin 3, so that the color steel tile 1 is connected with the purlin 3. The shape of the purlin 3 is not limited in the present application, and the shape of the purlin 3 can be adapted to the second recess 112, so as to further improve the connection effect of the purlin 3 and the color steel tile 1.

[0038] According to the present application, the purlin 3 is sleeved on the second recess 112, so that the color steel tile 1 is connected with the purlin 3. Compared with the way that the purlin 3 is connected with the color steel tile 1 by penetrating the purlin 3 with bolts, the present application does not need to punch holes on the color steel tile 1 and the purlin 3, and the installation method is simple. At the same time, the first recess 111 and the second recess 112 can be used for draining water on the panel body 11, so as to reduce the rust probability of the color steel tile 1.

[0039] In some optional embodiments, the inner cavity of the second recess 112 near one end of the first recess 111 gradually increases in the direction away from the first recess 111. Since the color steel tile 1 is made of metal material, it can be deformed to a certain extent. Therefore, the deformation of the first recess 111 and the second recess 112 can be controlled by external objects. In order to improve the stability of the connection between the purlin 3 and the color steel tile 1, after the purlin 3 is connected with the color steel tile 1, that is, after the purlin 3 is sleeved on the second recess 112 and extends into the mounting space 13, an external object is placed in the inner cavity of the second recess 112 and is driven to move towards the first recess 111, so that the connecting portion 1121 is deformed, the mounting space 13 is reduced, and the probability of the purlin 3 falling off the color steel tile 1 is reduced.

[0040] Since the inner cavity of the second recess 112 near one end of the first recess 111 gradually increases in the direction away from the first recess 111, the force application area of the external object on the second recess 112 is increased, and the deformation effect of the connecting portion 1121 is improved.

In this case, the purlin 3 is conformably arranged with the second recess 112, the end of the purlin 3 is in the shape of an isosceles trapezoid, and the small end of the second recess 112 faces the first recess 111, or the end of the purlin 3 is in the shape of a hexagon.

[0043] In some optional embodiments, the groove diameter of the first recess 111 gradually decreases in the direction towards the second recess 112. That is, the groove wall of the first recess 111 is arranged to be inclined, and the lower end of the inclined groove wall is connected with the second recess 112. The inclined arrangement of the first recess 111 can guide the rainwater to flow from the panel body 11 into the groove of the second recess 112, improve the smoothness of the rainwater flowing into the second recess 112, and further improve the drainage effect of the panel body 11.

[0044] In some optional embodiments, the bottom wall of the second recess 112 is arranged to be inclined, and the bottom wall of the second recess 112 is higher at one end than at the other end in the length direction, thereby improving the drainage effect of the second recess 112 and further improving the drainage effect of the panel body 11.

[0045] Referring to Figure 2 and Figure 6 In some optional embodiments, the locking edge 12 is located at the side edge of the panel body 11, and the locking edge 12 comprises a first locking portion 121, a second locking portion 122 and a third locking portion 123 connected in sequence.

The locking edge 12 is arranged at the side edge of the panel body 11, so as to be connected with the locking edge 12 of another color steel tile 1. The locking edge 12 is arranged at two opposite sides of the panel body 11, and the locking edge 12 is arranged to be parallel to the first recess 111.

[0047] The locking edge 12 comprises the first locking portion 121, the second locking portion 122 and the third locking portion 123. The first locking portion 121, the second locking portion 122 and the third locking portion 123 are made of the same material, and are integrally formed.

[0048] The first locking portion 121 is connected to the panel body 11 at an end away from the second locking portion 122, and is arranged at an angle to the panel body 11. In one example, the first locking portion 121 is arranged perpendicularly to the panel body 11. The third locking portion 123 is arranged at an angle to the panel body 11. In one example, the third locking portion 123 is arranged perpendicularly to the panel body 11. The second locking portion 122 connects the first locking portion 121 and the third locking portion 123, so that the first locking portion 121, the second locking portion 122, and the third locking portion 123 form the fixing cavity 124.

[0049] When two adjacent color steel tiles 1 need to be connected, the fixing cavity 124 of one color steel tile 1 can be sleeved on the locking edge 12 of the other color steel tile 1, so as to connect the two color steel tiles 1.

[0050] The present application does not limit the positions of the first locking portion 121 and the third locking portion 123 of the locking edge 12.
