Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaics, in particular to a color steel tile and a photovoltaic system. Background Art

[0002] With the advancement of photovoltaic power generation technology, the cost of photovoltaic power generation continues to decrease, and more and more industrial and civil buildings have begun to deploy photovoltaic power generation devices in locations such as roofs, walls, and exterior wall decorations. Color steel tiles are building components installed on the surface of buildings as "tiles". The color steel tiles in the related art are provided with matching male and female buckles at both ends, and there is also a mounting portion between the two ends of the color steel tiles, which is used to connect with photovoltaic modules. In specific use, multiple color steel tiles can be connected into color steel tile units by fastening the male and female buckles of adjacent color steel tiles. The mounting portion of each color steel tile supports and connects the photovoltaic modules. However, the photovoltaic modules connected to the photovoltaic tile units of the related art are prone to bending, deformation, hidden cracks, etc. after a period of use, which reduces the installation reliability of the photovoltaic modules. Utility Model Content

[0003] Based on this, it is necessary to provide a color steel tile and photovoltaic system that can improve the installation reliability of photovoltaic modules.

[0004] A first aspect of an embodiment of the present application provides a color steel tile, comprising a body, a first mounting member, and a second mounting member;

[0005] The first mounting member includes a first vertical wall and a transverse wall, the first vertical wall being vertically arranged at one end of the body, the transverse wall being cantilevered connected to the first vertical wall, and the transverse wall being provided with a mounting portion for connecting to a mounting assembly of the photovoltaic module;

[0006] The second mounting member includes a second vertical wall, which is vertically arranged at the other end of the body. The second vertical wall of the color steel tile is used to be detachably connected to the horizontal wall of the adjacent color steel tile;

[0007] When two adjacent color steel tiles are connected, the second vertical wall of one color steel tile and the first vertical wall and transverse wall of the other color steel tile define an installation space, which is used to connect with the installation support of the installation surface.

[0008] In one embodiment, the free end of the transverse wall is provided with a first locking edge, and the end of the second vertical wall away from the body is provided with a second locking edge;

[0009] The second locking edge of the color steel tile is used to lock with the first locking edge of the adjacent color steel tile.

[0010] In one embodiment, the height of the end of the first vertical wall facing away from the main body relative to the main body is higher than the height of the end of the second vertical wall facing away from the main body relative to the main body.

[0011] In one embodiment, the transverse wall is provided with a recessed portion that is recessed toward the main body, and the recessed portion forms a mounting portion.

[0012] In one embodiment, a clamping portion is provided on a surface of the first vertical wall facing the recessed portion, and the clamping portion is used to clamp and cooperate with the mounting bracket.

[0013] In one embodiment, the clamping portion is configured as a protrusion extending from the first vertical wall toward the recessed portion, and an included angle α between the clamping portion and the first vertical wall satisfies:

[0014] α≤30°.

[0015] In one embodiment, the main body is provided with a protrusion extending along a first direction, the protrusion is located between the first vertical wall and the second vertical wall, and the top end of the protrusion is set at a height relative to the main body that is lower than the first vertical wall and the second vertical wall, and the first direction is the length direction of the main body.

[0016] In one embodiment, the main body is further provided with a plurality of reinforcing ribs protruding along the thickness direction of the main body, the length direction of the reinforcing ribs is perpendicular to the first direction, a portion of the reinforcing ribs is located between the protruding portion and the first vertical wall, and another portion of the reinforcing ribs is located between the protruding portion and the second vertical wall.

[0017] In one embodiment, the ends of the first vertical wall and the second vertical wall connected to the body are both provided with a bending portion bent toward the body.

[0018] A second aspect of an embodiment of the present application provides a photovoltaic system, comprising at least the above-mentioned color steel tiles, wherein the horizontal wall of one adjacent color steel tile is connected to the second vertical wall of another color steel tile.

[0019] The beneficial effects of the above-mentioned colored steel tiles and photovoltaic systems are:

[0020] Since the first vertical wall is erected at one end of the main body, the transverse wall is cantileveredly connected to the first vertical wall, and the mounting portion is arranged on the transverse wall, the mounting portion is arranged at the end of the main body. Since the first vertical wall, the transverse wall and the second vertical wall located in different color steel tiles define an installation space, the installation space is used to connect with the mounting support of the installation surface. This is compared with the situation in the related art where the mounting portion is arranged in the middle of the color steel tile, and the position of the mounting portion in the thickness direction of the main body is uncertain during the installation of the photovoltaic module. Since the mounting portion is arranged at the end of the main body, the present application can be supported by the mounting support arranged in the installation space at the end of the main body, and the movement of the mounting portion in the thickness direction of the main body is limited by the mounting support. During the initial installation, when multiple color steel tiles are connected, it is easy to ensure that each mounting portion is at the same height. After installation, during use, the position on the photovoltaic module that cooperates with the mounting portion will not move, thereby avoiding the problem of bending, deformation and hidden cracks in the photovoltaic module.

[0021] In addition, a second vertical wall is erected at the other end of the main body. The second vertical wall of the color steel tile is used to detachably connect with the horizontal wall of the adjacent color steel tile. Therefore, the second vertical wall of one color steel tile can be used to support the free end of the horizontal wall of the adjacent color steel tile, creating installation space while also increasing the support strength of the installation part. Of course, it also saves the width of the color steel tile in the main body direction, making the overall structure more compact. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The following describes the color steel tiles and photovoltaic system of the embodiments of the present application with reference to the accompanying drawings.

[0040] Figure 1 A schematic diagram of the structure of the color steel tile provided in the embodiment of this application; Figure 2 A schematic diagram of the cooperation between the first mounting member and the second mounting member in adjacent color steel tiles; Figure 3 It is a structural diagram of the first mounting piece and the second mounting piece in adjacent color steel tiles cooperating with the mounting support; Figure 4 A schematic diagram of the three-dimensional structure of the color steel tile provided in the embodiment of the present application; Figure 5 for Figure 4 A local enlarged view of point A; Figure 6 A schematic diagram of the structure of a photovoltaic system provided in an embodiment of the present application; Figure 7 for Figure 6 A partial enlarged view of point B.

[0041] Reference Figure 1-Figure 7 The color steel tile 100 provided in the embodiment of the present application includes a body 101, a first mounting member 10, and a second mounting member 20. The first mounting member 10 includes a first vertical wall 11 and a horizontal wall 12. The first vertical wall 11 is vertically arranged at one end of the body 101. The horizontal wall 12 is cantilevered and connected to the first vertical wall 11. The horizontal wall 12 is provided with a mounting portion 120 for connecting to the mounting assembly of the photovoltaic module.

[0042] The second mounting member 20 includes a second vertical wall 21, which is erected at the other end of the main body 101. The second vertical wall 21 of the color steel tile 100 is used to detachably connect with the transverse wall 12 of the adjacent color steel tile 100. When two adjacent color steel tiles 100 are connected, the second vertical wall 21 of one color steel tile 100 and the first vertical wall 11 and transverse wall 12 of the other color steel tile 100 define an installation space C. The installation space C is used to connect with the mounting bracket 40 of the mounting surface. The mounting surface can be a roof, and the mounting bracket 40 is fixed to the roof purlin. The mounting bracket 40 is used to secure the color steel tile 100 to the purlin.

[0043] Since the first vertical wall 11 is erected at one end of the main body 101, the transverse wall 12 is cantilevered to the first vertical wall 11, and the mounting portion 120 is provided on the transverse wall 12, the mounting portion 120 is provided at the end of the main body 101, and the first vertical wall 11, the transverse wall 12, and the second vertical wall 21 located in two adjacent different color steel tiles 100 define an installation space C, and the installation space C is used to connect with the mounting support 40 of the installation surface. This is compared with the situation in the related art where the mounting portion is set in the middle of the color steel tile, and the position of the mounting portion in the thickness direction of the main body is uncertain during the installation of the photovoltaic module. The mounting portion 120 is set at the end of the main body 101 and can be supported by the mounting support 40 provided at the end of the main body 101. The mounting portion 120 is in the thickness direction H of the main body 101 (refer to Figure 1 The movement of the photovoltaic module 70 is restricted by the mounting bracket 40. During the initial installation, when multiple color steel tiles 100 are connected, since the multiple mounting brackets 40 are at the same height, it is easy to ensure that the various mounting portions 120 are at the same height. After the installation is completed, during use, the position on the photovoltaic module 70 that cooperates with the mounting portion 120 will not move, thereby avoiding the problems of bending, deformation, and hidden cracks in the photovoltaic module 70.

[0044] In addition, the second vertical wall 21 is erected at the other end of the body 101. The second vertical wall 21 of the color steel tile 100 is used to be detachably connected to the horizontal wall 12 of the adjacent color steel tile 100. Therefore, the second vertical wall 21 on one color steel tile 100 can be used to support the free end of the horizontal wall 12 of the adjacent color steel tile 100, forming the installation space C while also making the support strength of the installation part 120 higher. Of course, it can also save the color steel tile 100 in the width direction W of the body 101 (refer to Figure 1The dimensions along the width direction W (as shown) make the overall structure more compact. Of course, if the connected structure formed by connecting the second vertical walls 21 and transverse walls 12 of adjacent color steel tiles 100 is relatively compact, the dimensions of the main body 101 in this width direction W can be increased, thereby increasing the size of the entire color steel tile 100 and improving space utilization. For example, the dimension of a single color steel tile 100 along this direction can be 804 mm. Furthermore, the heights of the first vertical walls 11 and the second vertical walls 21 can be set higher to improve the waterproof performance of the color steel tile 100.

[0045] It is understandable that because the mounting portion 120 is provided at the end of the main body 101, when the color steel tile 100 is formed in one piece, the stress during the rolling process can be released through the first mounting member 10, thereby improving the forming rate of the color steel tile 100. Specifically, in the rolling process of the related art, the rolling of the substrate is achieved by moving two sets of rolling wheels from both sides of the width direction of the substrate to the center. In this way, the closer to the center of the width direction of the substrate, the more concentrated the stress. Compared with the central part, the stress concentration problem on both sides of the width direction of the substrate is relatively mild. In the embodiment of the present application, because the mounting portion 120 is provided at the end of the main body 101, and the mounting portion 120 includes a semi-open structure formed by the first vertical wall 11 and the horizontal wall 12, during the rolling process, the stress is also relatively easy to release through the open position.

[0046] Furthermore, the first vertical wall 11 and the transverse wall 12 may be integrally formed or separately formed. In the embodiments of this application, an integral formation is used as an example for illustration. The first vertical wall 11, the second vertical wall 21, and the transverse wall 12 may be plate-like members extending along a first direction S. The first direction S is the longitudinal direction of the body 101. The transverse wall 12 being cantilevered from the first vertical wall 11 means that one end of the transverse wall 12 is connected to the first vertical wall 11, while the other end is suspended and unsupported by other components.

[0047] In the embodiment of the present application, the free end of the horizontal wall 12 is provided with a first locking edge 13, and the end of the second vertical wall 21 away from the main body 101 is provided with a second locking edge 22. The second locking edge 22 of the color steel tile 100 is used to lock with the first locking edge 13 of the adjacent color steel tile 100. With such a configuration, when there are multiple color steel tiles 100, the connection of each color steel tile 100 can be achieved by locking the first locking edge 13 and the second locking edge 22 of each two adjacent color steel tiles 100. Here, the first locking edge 13 and the second locking edge 22 can also extend along the first direction. In specific implementation, such as Figure 7 As shown, the first locking edge 13 and the second locking edge 22 are not locked. Figure 2 The state shown is that the first locking edge 13 and the second locking edge 22 are locked.

[0048] Reference Figure 7The first locking edge 13 includes a first sub-section 131 and a second sub-section 132 connected to each other. The side of the first sub-section 131 facing away from the second sub-section 132 is connected to the transverse wall 12. The second locking edge 22 includes a third sub-section 221 and a fourth sub-section 222 connected to each other. The side of the third sub-section 221 facing away from the fourth sub-section 222 is connected to the second vertical wall 21. In the unlocked state, the first locking edge 13 covers the outside of the second locking edge 22. The first sub-section 131 and the third sub-section 221 are arranged corresponding to each other and are arranged approximately parallel to the main body 101. The second sub-section 132 and the fourth sub-section 222 are arranged corresponding to each other and are arranged approximately along the thickness direction H of the main body 101.

[0049] Reference Figure 2 When locking, under the action of the locking tool, the second sub-section 132 rotates clockwise, driving the fourth sub-section 222 to rotate clockwise as well, until the fourth sub-section 222 is attached to the third sub-section 221. At this time, the second sub-section 132 is also attached to the fourth sub-section 222.

[0050] In the present application, continue to refer to Figure 1 The end of the first vertical wall 11 facing away from the main body 101 is positioned at a higher height relative to the main body 101 than the end of the second vertical wall 21 facing away from the main body 101. In this way, when multiple color-coated steel tiles 100 are connected, the second vertical wall 21 of one color-coated steel tile 100 is located at the bottom of the free end of the transverse wall 12 of the adjacent color-coated steel tile 100, providing support for the free end of the transverse wall 12 of the adjacent color-coated steel tile 100. Only after the first locking edge 13 overlaps and locks with the second locking edge 22 can the main bodies 101 of the two adjacent color-coated steel tiles 100 be flush. The height of the end of the second vertical wall 21 facing away from the main body 101 relative to the main body 101 can be, for example, 82 mm, and the height of the end of the first vertical wall 11 facing away from the main body 101 can be, for example, 85 mm.

[0051] Further, continue to refer to Figure 2 、 Figure 3 The horizontal wall 12 is provided with a recessed portion 121 that is recessed toward the main body 101, and the recessed portion 121 forms the mounting portion 120. Of course, the area around the recessed portion 121 on the horizontal wall 12 forms a support surface for the photovoltaic module 70. The support surface is part of the horizontal arm 12.

[0052] In the embodiment of the present application, when two color steel tiles 100 are connected, the recessed portion 121 and the first vertical wall 11 and the second vertical wall 21 jointly define an installation space C. As mentioned above, the installation space C is used to accommodate the installation support 40 of the installation surface.

[0053] A snap-fit ​​portion 80 is provided on one side of the first wall 11 facing the recessed portion 121. The snap-fit ​​portion 80 is configured to snap-fit ​​with the mounting bracket 40. For example, the mounting bracket 40 is provided with a snap-fit ​​groove 41. When the mounting bracket 40 is installed in the mounting space C, the snap-fit ​​portion 80 is snap-fitted into the snap-fit ​​groove 41.

[0054] Of course, the surface of the recessed portion 121 located within the installation space C is further provided with an escape space D for the positioning portion 42 on the installation support 40 to be inserted.

[0055] In the present application, refer to Figure 2 and Figure 3 The clamping portion 80 is constructed as a protrusion extending from the first vertical wall 11 to the recessed portion 121, and the angle α between the clamping portion 80 and the first vertical wall 11 satisfies: α≤30°. If the angle α is greater than 30°, the clamping portion 80 of the mounting bracket 40 will easily fall out of the clamping groove 41. In addition, if the angle α is greater than 30°, the angle between the wall portion of the first vertical wall 11 corresponding to the clamping portion 80 and the horizontal plane will become smaller, that is, the setting posture will become flatter, so that in conditions such as strong winds, the wind-exposed area of ​​this position will be larger. By satisfying the angle α of α≤30, the clamping portion 80 will not easily fall out of the clamping groove 41, which can improve the bonding strength between the first vertical wall 11 and the mounting bracket 40. In addition, the wind-exposed area of ​​the wall portion of the first vertical wall 11 corresponding to the clamping portion 80 is smaller, thereby effectively enhancing the overall wind resistance of the color steel tile 100.

[0056] Further, refer to Figure 4 The main body 101 is provided with a raised portion 30 extending along a first direction. The raised portion 30 is located between the first vertical wall 11 and the second vertical wall 21, and the top portion of the raised portion 30 is lower than the height of the first vertical wall 11 and the second vertical wall 21 relative to the main body 101. The first direction S is the length direction of the main body 101. In this way, a large space can be defined between the first vertical wall 11 and the second vertical wall 21 and the main body 101 as a drainage trough, which can quickly drain rainwater from the color steel tile 100. At the same time, it can also effectively improve the heat dissipation of the photovoltaic module 70, thereby ensuring power generation. In addition, the raised portion 30 can serve as a supporting structure for the middle part of the main body 101, thereby achieving the effect of strengthening the strength of the middle part of the main body 101.

[0057] In the embodiment of the present application, the main body 101 is further provided with a plurality of reinforcing ribs 50 protruding along the thickness direction H of the main body 101. Some of the reinforcing ribs 50 are located between the raised portion 30 and the first vertical wall 11, while other portions of the reinforcing ribs 50 are located between the raised portion 30 and the second vertical wall 21. This provides good support for the color steel tile 100 and effectively prevents deformation caused by being stepped on during construction.

[0058] Further, refer to Figure 3The ends of the first and second vertical walls 11 and 21 connected to the main body 101 are each provided with a bent portion 60 that bends toward the main body 101. The provision of the bent portion 60 can improve the connection strength between the first and second vertical walls 11 and 21 and the main body 101. During construction, workers will stand on top of the first mounting member 10. If the bent portion 60 is not provided, the worker can easily deform the first mounting member 10 by stepping lightly. If the bent portion 60 is provided, the first vertical wall 11 has multiple bends, which makes it less likely to deform than a straight first vertical wall 11, thereby improving the connection strength between the first and second vertical walls 11 and 21 and the main body 101.

[0059] Reference Figure 6 、 Figure 7 In a second aspect of an embodiment of the present application, a photovoltaic system 200 is provided, comprising at least two of the above-mentioned color steel tiles 100 , wherein the horizontal wall 12 of one of the adjacent color steel tiles 100 is connected to the second vertical wall 21 of the other color steel tile 100 .

[0060] Specifically, the first locking edge 13 of one color steel tile 100 and the second locking edge 22 of another color steel tile are locked to each other to achieve the connection between adjacent color steel tiles 100.

[0061] In the embodiment of the present application, the mounting assembly of the photovoltaic assembly 70 may include a special-shaped nut and a pressure block. During installation, the photovoltaic assembly 70 is secured to the mounting portion 120 via the special-shaped nut and the pressure block. The special-shaped nut is positioned within the recessed portion 121, and the pressure block is secured to the special-shaped nut. The pressure block is also connected to the photovoltaic assembly 70 by a mortise and tenon joint. Finally, a dedicated electric locking tool is used to lock the first and second locking edges 13 and 22. Repeating the above process completes the connection between each color-coated steel tile 100 and the photovoltaic assembly 100.

[0062] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0063] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
