Description

Technical Field

[0001] The utility model relates to the photovoltaic field, in particular to a roof fixing structure of a lightweight photovoltaic component. Background Art

[0002] Conventional photovoltaic modules are typically secured to color-coated steel tile roofs using specially designed fixtures. A common fixture type is the color-coated steel tile fixture, which secures directly to the crests or troughs of the tiles, providing stable support for the photovoltaic module. The fixture's design typically takes into account the corrugated structure of the tiles, so the bottom of the fixture is typically designed to match the shape to better fit the tile surface. Furthermore, the fixture is equipped with specialized locking devices, such as bolts or clips, to securely fasten the photovoltaic module to the fixture.

[0003] However, for certain types of color-coated steel tile roofs, such as trapezoidal ones or those with narrow crests, the lack of suitable fixtures often leads to the practice of drilling holes and using waterproof glue to secure PV panels. While this method may seem feasible in the short term, it inevitably introduces the risk of leakage in the long term.

[0004] In addition, due to structural load limitations on some roofs, standard photovoltaic modules cannot be used. In this case, if lightweight photovoltaic modules must be used, traditional photovoltaic module clamps will not be able to fix these thin and lightweight photovoltaic modules.

[0005] Therefore, it is necessary to provide a new roof fixing structure for lightweight photovoltaic modules to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a roof fixing structure for lightweight photovoltaic modules, so as to solve the problem that photovoltaic modules cannot be stably installed in narrow areas of trapezoidal color steel tile roofs or crest tops.

[0007] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0008] A roof fixing structure for a lightweight photovoltaic module, comprising:

[0009] The color steel tile comprises a plurality of planar portions and convex ridge portions arranged alternately along a first direction;

[0010] Photovoltaic modules, wherein the photovoltaic modules are lightweight photovoltaic modules, are arranged on the color steel tiles, and multiple rows of the photovoltaic modules are arranged along the first direction, and each row of the photovoltaic modules is arranged along a second direction, and the second direction is perpendicular to the first direction;

[0011] A fixing part, wherein a plurality of the fixing parts are spaced apart along the first direction between the color steel tile and the photovoltaic module, the lower surface of the fixing part is in contact with the planar portion, the upper surface of the fixing part is in contact with the lower surface of the photovoltaic module, and the height of the fixing part is not less than the distance between the highest point of the convex ridge portion and the planar portion.

[0012] As a further improved technical solution of the present invention, the fixing member and the color steel tile, and the fixing member and the photovoltaic module are fixedly connected by structural adhesive respectively.

[0013] As a further improved technical solution of the present invention, the fixing part is in the shape of a hollow square tube, and the fixing part includes an enclosed upper wall, a lower wall and two side walls. The upper wall is parallel to the lower wall, and the upper wall is at least partially in contact with the lower surface of the photovoltaic component, and the lower wall is at least partially in contact with the planar portion.

[0014] As a further improved technical solution of the present invention, the fixing member includes a first fixing member and a second fixing member arranged in parallel, the two first fixing members are arranged on both sides of the photovoltaic component, and a plurality of second fixing members are arranged at intervals between the two first fixing members, and the length of the first fixing member is greater than the length of the second fixing member.

[0015] As a further improved technical solution of the present invention, the first fixing member also includes a first limiting wall, which is perpendicular to the upper wall, and the projection of the photovoltaic component in the first direction at least partially overlaps with the projection of the first limiting wall in the first direction.

[0016] As a further improved technical solution of the present invention, at least part of the lower surface of the mutually adjacent side of the two rows of photovoltaic components adjacent to each other along the first direction is adhered to the upper wall of the same first fixing member, and is respectively located on both sides of the first limiting wall of the first fixing member.

[0017] As a further improved technical solution of the present invention, at least one photovoltaic module is connected to each of the first fixing members along the second direction, and the length of the first fixing member is equivalent to the sum of the widths of the at least one photovoltaic module in the second direction.

[0018] As a further improved technical solution of the present invention, the second fixing member also includes a second limiting wall, which is perpendicular to the upper wall and perpendicular to the first limiting wall, and the projection of the photovoltaic component in the second direction at least partially overlaps with the projection of the second limiting wall in the second direction.

[0019] As a further improved technical solution of the present invention, at least part of the lower surface of the side close to each other in the two adjacent rows of photovoltaic components along the second direction is adhered to the upper wall of the second fixing members in the same row arranged along the first direction, and are respectively located on both sides of the second limiting wall of the second fixing members.

[0020] As a further improved technical solution of the present invention, the fixing piece is made of metal.

[0021] Compared with the existing technology, the beneficial effect of the roof fixing structure of the lightweight photovoltaic module of the present invention is that the photovoltaic module is fixed and installed by laying fixing parts on the flat part of the color steel tile, and the height of the fixing parts is not less than the distance between the highest point of the convex part of the color steel tile and the flat part, without damaging the original roof structure and waterproofing, and non-destructive installation can be achieved. Compared with the traditional clamp installation scheme, the entire photovoltaic system of the present invention is lighter, has lower requirements on the bearing capacity of the original roof, and has higher adaptability; such a design not only takes into account the load-bearing capacity, but also takes into account the drainage function, ensuring that rainwater can flow smoothly from the roof, avoiding water accumulation and damage to the roof or photovoltaic modules. The roof fixing structure of the lightweight photovoltaic module is simple in structure, which effectively solves the problem that some color steel tile roofs cannot be installed with clamps, and at the same time solves the installation problem of lightweight photovoltaic modules on color steel tile roofs.

[0037] See also Figures 1 to 7As shown, the utility model discloses a roof fixing structure of a lightweight photovoltaic module, including a color steel tile 1, a photovoltaic module 2 and a fixing part 3, the fixing part 3 is fixedly laid on the color steel tile 1, the photovoltaic module 2 is fixedly installed on the fixing part 3, and the photovoltaic module 2 is a lightweight photovoltaic module.

[0038] To facilitate the description of the embodiments of the present invention, a first direction and a second direction are set to assist in the explanation, wherein D1 in the figure represents the first direction, D2 represents the second direction, and the first direction and the second direction are perpendicular to each other.

[0039] It should also be noted that in order to better absorb light energy, the roof of the present invention is horizontal or inclined, and the color steel tiles 1, photovoltaic modules 2 and fixings 3 are arranged horizontally or inclined in accordance with the roof. Therefore, the up and down directions in the present invention refer to the up and down directions perpendicular to the photovoltaic modules 2.

[0040] See also Figure 1 and Figure 3 As shown, the color steel tile 1 includes several planar portions 11 and convex portions 12 arranged alternately along a first direction D1-D1. Photovoltaic modules 2 are mounted on the color steel tile 1, with multiple rows of photovoltaic modules 2 arranged along the first direction D1-D1, and each row of photovoltaic modules 2 arranged along a second direction D2-D2. Multiple fixings 3 are spaced along the first direction D1-D1 between the color steel tile 1 and the photovoltaic modules 2. The lower surfaces of the fixings 3 mate with the planar portions 11, and the upper surfaces of the fixings 3 mate with the lower surfaces of the photovoltaic modules 2. Furthermore, the height of the fixings 3 is no less than the distance between the highest point of the convex portions 12 and the planar portion 11. This arrangement eliminates the need for bolted fastening, does not damage the existing roof structure or waterproofing, and allows for non-destructive installation.

[0041] In some embodiments, the height of the fixing member 3 is equal to the distance between the highest point of the convex portion 12 and the plane portion 11 , so that the top of the convex portion 12 abuts against the photovoltaic module 2 to enhance the installation stability of the photovoltaic module 2 .

[0042] In other embodiments, the height of the fixing member 3 is greater than the distance between the highest point of the convex portion 12 and the flat portion 11, so that there is no contact between the photovoltaic component 2 and the color steel tile 1, and both are not easily damaged.

[0043] Furthermore, the fixing part 3 and the color steel tile 1, and the fixing part 3 and the photovoltaic module 2 are fixedly connected by structural adhesive 4 respectively to strengthen the connection strength between the fixing part 3 and the color steel tile 1 and the connection strength between the fixing part 3 and the photovoltaic module 2, thereby strengthening the stability of the photovoltaic module 2 installed on the color steel tile 1.

[0044] When the height of the fixing member 3 is equal to the distance between the highest point of the convex portion 12 and the plane portion 11 , the convex portion 12 and the photovoltaic module 2 are also fixedly connected by the structural adhesive 4 to further enhance the installation stability of the photovoltaic module 2 .

[0045] See also Figure 3 and Figure 7 As shown, the fixing member 3 of this embodiment is in the shape of a hollow square tube and includes an enclosed upper wall 31, a lower wall 32, and two side walls 33. The upper wall 31 is parallel to the lower wall 32, and the two side walls 33 are parallel to each other. The upper wall at least partially mates with the lower surface of the photovoltaic module 2, and the lower wall 32 at least partially mates with the planar portion 11. This arrangement provides the fixing member 3 with a high load-bearing capacity while also providing drainage, ensuring that rainwater can flow smoothly off the roof, preventing water accumulation from damaging the roof and the photovoltaic module 2.

[0046] In other embodiments, the two side walls 33 of the fixing member 3 are not parallel, and the cross-section of the fixing member 3 may be a trapezoid or other quadrilateral shape. Alternatively, the fixing member 3 may include other walls in addition to the upper wall 31, the lower wall 32, and the two side walls 33, that is, the cross-section of the fixing member 3 is a polygon with four or more sides.

[0047] See also Figure 1 As shown, the fixing member 3 includes a first fixing member 301 and a second fixing member 302 arranged in parallel. The two first fixing members 301 are arranged on both sides of the photovoltaic module 2 along the first direction D1-D1, and the multiple second fixing members 302 are spaced between the two first fixing members 301. In other words, both sides of the photovoltaic module 2 in the first direction D1-D1 are supported and fixed on the first fixing members 301, and the middle part of the photovoltaic module 2 is supported by the multiple second fixing members 302. This arrangement can provide a high supporting force for the photovoltaic module 2. Furthermore, the length of the first fixing member 301 is greater than that of the second fixing member 302.

[0048] See also Figure 1 As shown, in this embodiment, the two sides of the photovoltaic module 2 parallel to the first direction D1-D1 are long sides, and the two sides of the photovoltaic module 2 parallel to the second direction D2-D2 are short sides. Specifically, the long sides of the photovoltaic module 2 are at least partially supported on the first fixing member 301, and the short sides of the photovoltaic module 2 are at least partially supported on the second fixing member 302. The first fixing member 301 is provided along the entire length, while the second fixing member 302 is provided in sections, which can ensure good support stability and reduce costs.

[0049] Furthermore, at least one photovoltaic module 2 is connected to each first fixing member 301 along the second direction D2-D2, and the length of the first fixing member 301 is equivalent to the sum of the widths of the at least one photovoltaic module 2 along the second direction. For example, if two photovoltaic modules 2 are supported on each first fixing member 301 along the second direction D2-D2, the length of the first fixing member 301 is equivalent to the sum of the short sides of the two photovoltaic modules 2. Furthermore, at least a portion of the lower surface of the adjacent side of two adjacent rows of photovoltaic modules 2 along the second direction D2-D2 abuts against the second fixing members 302 arranged in the same row along the first direction D1-D1. That is, two photovoltaic modules 2 with adjacent long sides have their adjacent long sides supported by the same row of second fixing members 302. In this way, the photovoltaic modules 2 adjacent along the first direction D1-D1 and the photovoltaic modules 2 adjacent along the second direction D2-D2 are located at the same installation height. This simple arrangement of fixing members 3 achieves good stability and consistency of the photovoltaic modules 2, and also provides good waterproofing.

[0050] See also Figures 3 to 5 As shown, the first fixing member 301 also includes a first limiting wall 34, which is vertically fixed to the upper wall 31 of the first fixing member 301. The projection of the photovoltaic assembly 2 in the first direction D1-D1 at least partially overlaps with the projection of the first limiting wall 34 in the first direction D1-D1, and the first limiting wall 34 is parallel to the short side of the photovoltaic assembly 2. This arrangement can further limit the position of the photovoltaic assembly 2 in the first direction D1-D1, thereby improving the installation efficiency of the photovoltaic assembly 2 and preventing the photovoltaic assembly 2 from falling off. Furthermore, at least a portion of the lower surface of the adjacent side of two rows of photovoltaic assemblies 2 along the first direction D1-D1 is in contact with the upper wall 31 of the same first fixing member 301, and is located on both sides of the first limiting wall 34 of the first fixing member 301. The two first fixing members 301 connected to the two short sides of the photovoltaic modules 2 located on both sides along the first direction D1-D1, close to the outside, each support and connect only one photovoltaic module 2. In order to improve the support stability of the photovoltaic modules 2, the first fixing member 301 here sets the first limiting wall 34 at one end of the upper wall 31 along the first direction D1-D1 to increase the contact area between the upper wall 31 and the photovoltaic modules 2, which can improve the support stability while limiting the photovoltaic modules 2. The first fixing member 301 shared by two adjacent rows of photovoltaic modules 2 along the first direction D1-D1 has its first limiting wall 34 set at the midline of the upper wall 31 along the first direction D1-D1, so that the contact area between the upper wall 31 of the first fixing member 301 and the two rows of photovoltaic modules 2 is equal, which can improve the support stability and consistency while limiting the two adjacent rows of photovoltaic modules 2.

[0051] See also Figure 1 、 Figure 2 and Figure 6As shown, the second fixing member 302 also includes a second limiting wall 35, which is vertically fixed to the upper wall 31 of the second fixing member 302. The second limiting wall 35 is perpendicular to the first limiting wall 34. The projection of the photovoltaic assembly 2 in the second direction D2-D2 at least partially overlaps with the projection of the second limiting wall 35 in the second direction D2-D2, and the second limiting wall 35 is parallel to the long side of the photovoltaic assembly 2. This arrangement can further limit the position of the photovoltaic assembly 2 in the second direction D2-D2, improve the installation efficiency of the photovoltaic assembly 2, and prevent the photovoltaic assembly 2 from falling off. Furthermore, at least a portion of the lower surface of the adjacent side of two adjacent rows of photovoltaic assemblies 2 along the second direction D2-D2 is in contact with the upper wall 31 of the same row of second fixing members 302 arranged along the first direction D1-D1, and is respectively located on both sides of the second limiting wall 35 of the second fixing member 302. The two rows of second fixing members 302 connected to the two long sides of the photovoltaic modules 2 located on both sides along the second direction D2-D2, each supporting and connecting only one photovoltaic module 2. To improve the support stability of the photovoltaic modules 2, the second fixing members 302 here set the second limiting wall 35 at one end of the upper wall 31 along the second direction D2-D2 to increase the contact area between the upper wall 31 and the photovoltaic modules 2, thereby improving the support stability while limiting the photovoltaic modules 2. The second fixing member 302 shared by the two adjacent rows of photovoltaic modules 2 along the second direction D2-D2 has its second limiting wall 35 set at the midline of the upper wall 31 along the second direction D2-D2, so that the contact area between the upper wall 31 of the second fixing member 302 and the two rows of photovoltaic modules 2 is equal, thereby improving the support stability and consistency while limiting the two adjacent rows of photovoltaic modules 2.

[0052] The first limiting wall 34 and the second limiting wall 35 limit the photovoltaic assembly 2 in the first direction D1 - D1 and the second direction D2 - D2 respectively, thereby effectively improving the installation efficiency and overall structural stability of the photovoltaic assembly 2 .

[0053] In this embodiment, the fixing member 3 is made of metal, preferably aluminum, which has high strength and low weight, ensuring sufficient support for the photovoltaic module 2 while having low requirements on the bearing capacity of the roof.

[0054] In summary, compared with the prior art, the roof fixing structure of the lightweight photovoltaic module of the present invention has the following advantages: by laying the fixing parts 3 on the flat part 11 of the color steel tile 1, the photovoltaic module 2 is fixedly installed, and the height of the fixing parts 3 is not less than the distance between the highest point of the convex part 12 of the color steel tile 1 and the flat part 11, without damaging the original roof structure and waterproofing, and non-destructive installation can be achieved. Compared with the traditional clamp installation scheme, the entire photovoltaic system of the present invention is lighter, has lower requirements on the bearing capacity of the original roof, and has higher adaptability; such a design not only takes into account the load-bearing capacity, but also takes into account the drainage function, ensuring that rainwater can flow smoothly from the roof, avoiding water accumulation and causing damage to the roof or photovoltaic module 2. The roof fixing structure of the lightweight photovoltaic module is simple in structure, which effectively solves the problem that some color steel tile roofs cannot be installed with clamps, and at the same time solves the installation problem of lightweight photovoltaic modules on color steel tile roofs.

The understanding of this specification should be based on technical personnel in the relevant technical field. Although this specification has described the present invention in detail with reference to the above embodiments, ordinary technical personnel in this field should understand that technical personnel in the relevant technical field can still modify or replace the present invention with equivalents, and all technical solutions and improvements that do not depart from the spirit and scope of the present invention should be covered by the scope of the claims of the present invention.
