[0002] As a low-carbon renewable energy source, solar energy has many advantages. Not only is it free to use, but it also does not require transportation and does not pollute the environment. Compared with traditional energy sources, solar energy is easy to use and low in cost. Solar photovoltaic panels can directly convert solar energy into electrical energy to power electrical equipment or transmit electrical energy to the power grid, meeting the demand for electricity in today's society.

[0003] At present, installing photovoltaic panels on building roofs is becoming an increasingly popular choice. For color steel tile roofs, metal brackets are currently used to fix photovoltaic panels. Not only are the bracket components complex in structure and difficult to install, but they are also heavy, which can easily cause deformation of the color steel tile roof. Moreover, if low-cost steel is used, corrosion problems are very likely to occur, resulting in poor stability of the photovoltaic panels after long-term use. If aluminum alloy materials are used, although the corrosion problem is effectively solved and the stability of the photovoltaic panels is guaranteed for long-term use, the cost is very high, which is beyond the acceptance range of many users.

[0004] Solving the above problems has become a top priority. Utility Model Content

[0026] The utility model is further described below in conjunction with embodiments and drawings.

[0027] like Figure 1-Figure 8As shown, a structure for modularly installing photovoltaic panels on a color steel tile roof using a composite material bracket mainly includes a color steel tile roof 1 and a plurality of photovoltaic panels 2 installed on the color steel tile roof 1 through the composite material bracket. In this embodiment, the guide rail 3 used in the largest amount in the composite material bracket is made of glass fiber reinforced composite material, which is not only low in cost and reduces the financial threshold for installing photovoltaic panels on the color steel tile roof, but also light in weight and can avoid deformation of the color steel tile roof. At the same time, the structural strength of the glass fiber reinforced composite material is equivalent to that of metal materials such as steel and aluminum alloy, and it has excellent corrosion resistance. It can withstand the long-term test of harsh weather conditions and is durable, thus ensuring the stability and reliability of the installation of the photovoltaic panels.

[0028] It should be pointed out that glass fiber reinforced composite material refers to a material that is composited by a certain molding process using glass fiber and its products as reinforcing materials and matrix materials. Among them, the reinforcement of glass fiber reinforced composite material is glass fiber, and the matrix material is epoxy resin. It can be formed by hand lay-up, winding, pressing and other molding processes, or injection and pultrusion molding processes. In this embodiment, the guide rail 3 is made of glass fiber reinforced composite material profiles, and the cross-sectional area of ​​the profile is 494.37mm 2 The density of glass fiber reinforced composite materials is 1.4g / cm 3 Compared with metals, glass fiber reinforced composites have lower density, so under the same size, they have lighter weight.

[0029] Specifically, the composite material support includes at least one set of photovoltaic panel mounting tracks consisting of two mutually parallel guide rails 3, that is, the composite material support includes at least one set of photovoltaic panel mounting tracks, and each set of photovoltaic panel mounting tracks consists of two mutually parallel guide rails 3. The guide rails 3 each have an upper guide rail groove 3a and a lower guide rail groove 3b distributed up and down, and the upper guide rail groove 3a and the lower guide rail groove 3b both extend along the length direction of the guide rail 3, and the notch of the upper guide rail groove 3a is opened on the top surface of the guide rail 3, and the notch of the lower guide rail groove 3b is opened on the bottom surface of the guide rail 3, and the notch of the upper guide rail groove 3a and the notch of the lower guide rail groove 3b also extend along the length direction of the guide rail 3. Both sides of the notch of the upper guide rail groove 3a are folded inward to form an upper guide groove flange 3a1, and both sides of the notch of the lower guide rail groove 3b are folded inward to form a lower guide groove flange 3b1.

[0030] See also Figure 1 , Figure 5 and Figure 6At least two guide rail mounting frames 4 are installed on the lower sliding groove 3b of each guide rail so as to be locked or unlocked by corresponding locking components 7. The guide rail mounting frames 4 are installed on the corresponding convex ridges 1a of the color steel tile roof 1, so that the guide rail 3 can be reliably fixed on the corresponding convex ridges 1a of the color steel tile roof 1, which is simple, reliable and easy to install. It should be pointed out that the number of guide rail mounting frames 4 can be flexibly adjusted according to the length of the guide rail 3.

[0031] Specifically, the guide rail mounting frame 4 includes a guide rail support plate 4b adapted to the two sliding groove flanges 3b1 of the corresponding guide rail lower sliding groove 3b and an elastic clamp 4a fixedly connected to the guide rail support plate 4b. The elastic clamp 4a can be elastically clamped on the corresponding ridge 1a, thereby achieving a reliable connection with the color steel tile roof 1, and the elastic clamp 4a is elastic, so that it can adapt to ridges 1a of different sizes, and has good versatility.

[0032] The guide rail support plate 4b is provided with a first bolt through hole 4b1 matched with the locking bolt 7b, and the screw portion of the locking bolt 7b passes through the first bolt through hole 4b1 and is tightened in the threaded hole of the corresponding locking block 7a, so that the guide rail support plate 4b is pressed against the two sliding groove flanges 3b1 of the corresponding guide rail lower sliding groove 3b, thereby locking the guide rail mounting frame 4 on the corresponding convex ridge 1a of the color steel tile roof 1. When it is necessary to unlock the guide rail mounting frame 4, the locking bolt 7b can be loosened in the reverse direction, and at this time, the relative position of the guide rail mounting frame 4 and the guide rail 3 can be adjusted.

[0033] Furthermore, the inner surface of the elastic clamp 4a and the side surface of the guide rail support plate 4b close to the lower slide groove 3b of the guide rail are both processed with anti-slip teeth 4c. By providing the anti-slip teeth 4c, the reliability of the elastic clamp 4a clamping the ridge 1a and the reliability of the locking bolt 7b locking the guide rail mounting frame 4 and the guide rail 3 can be effectively improved, thereby avoiding the problem of loosening and slipping.

[0034] Furthermore, the elastic clamping jaw 4a includes a first clamping jaw piece and a second clamping jaw piece that are arranged opposite to each other. The first clamping jaw piece and the second clamping jaw piece are locked by rivets or bolts, which is simple and reliable. The guide rail support plate 4b is integrally formed on the first clamping jaw piece or the second clamping jaw piece.

[0035] See also Figure 1 , Figure 7 and Figure 8The guide rails 3 each include at least two guide rail sections 3' which are connected in sequence along the length direction. Adjacent guide rail sections 3' are connected by a guide rail connecting assembly 8. The guide rail connecting assembly 8 includes a tightening block 8a located in the guide rail upper slide groove 3a and two long bolts 8b which form a screw-nut kinematic pair with the tightening block 8a. The tightening block 8a is adapted to the two upper slide groove flanges 3a1 of the two adjacent guide rail sections 3'. The two long bolts 8b are each located in a guide rail section 3', and the outer ends of the screw parts of the two long bolts 8b are respectively rotatably supported on the bottom of the guide rail upper slide groove 3a of the corresponding guide rail section 3', so that the tightening block 8a is pressed against the two upper slide groove flanges 3a1 of the two adjacent guide rail sections 3' from the inside to the outside. When it is necessary to fix two adjacent guide rail sections 3', the two long bolts 8b are rotated so that the two ends of the tightening block 8a respectively press upward against the upper slide groove flanges 3a1 of the two guide rail sections 3'. At this time, the lower ends of the two long bolts 8b press downward against the bottom of the guide rail upper slide groove 3a of the two guide rail sections 3'. This is simple and reliable, and ensures the reliable connection of the adjacent guide rail sections 3', so that the length of the guide rail 3 can be adaptively adjusted by increasing or decreasing the number of guide rail sections 3' according to needs, thereby realizing modular design.

[0036] See also Figure 1-Figure 4 , the slide grooves 3a on each guide rail can be locked or unlocked by corresponding locking components 7 to install two single-sided positioning buckles 5 and at least one double-sided positioning buckle 6 located between the two single-sided positioning buckles 5.

The outer edges of the photovoltaic panels 2 at the middle are respectively inserted into the corresponding two double-sided positioning buckles 6, which ensures the reliable installation of the photovoltaic panels 2 and is suitable for photovoltaic panels 2 of different sizes. The installation process is simple and flexible. It should be pointed out that the double-sided positioning buckles 6 can be flexibly adjusted according to the number of photovoltaic panels 2. The more photovoltaic panels 2 there are, the more double-sided positioning buckles 6 there are.

[0037] The locking components 7 include a locking block 7a that is adapted to the two upper slide groove flanges 3a1 of the corresponding upper slide groove 3a of the guide rail or the two lower slide groove flanges 3b1 of the corresponding lower slide groove 3b of the guide rail, and a locking bolt 7b that is threadedly matched with the locking block 7a. Each locking bolt 7b can tighten the locking block 7a and the guide rail mounting frame 4 or the single-sided positioning buckle 5 or the double-sided positioning buckle 6 on both sides of the corresponding two upper slide groove flanges 3a1 or the corresponding two lower slide groove flanges 3b1.

[0038] That is, when the locking assembly 7 is installed on the upper slide groove 3a of the guide rail, tightening the locking bolt 7b can tighten the single-side positioning buckle 5 or the double-side positioning buckle 6 on the corresponding two upper slide groove flanges 3a1, and loosening the locking bolt 7b, the single-side positioning buckle 5 or the double-side positioning buckle 6 can slide along the upper slide groove 3a of the guide rail; when the locking assembly 7 is installed on the lower slide groove 3b of the guide rail, tightening the locking bolt 7b can tighten the guide rail mounting frame 4 on the corresponding two lower slide groove flanges 3b1, and loosening the locking bolt 7b, the guide rail mounting frame 4 can slide along the lower slide groove 3b of the guide rail. It is simple and reliable, easy to assemble, and has good versatility, and can adapt to photovoltaic panels 2 of different sizes.

[0039] Furthermore, the locking block 7a is recessed on one side close to the upper slide groove flange 3a1 or the lower slide groove flange 3b1 to form two positioning grooves 7a1, and the inner side of each upper slide groove flange 3a1 and each lower slide groove flange 3b1 is protruded with a positioning rib 3c that is compatible with the corresponding positioning groove 7a1, and each positioning rib 3c can be embedded in the corresponding positioning groove 7a1, thereby further improving the reliability of the locking block 7a and the two upper slide groove flanges 3a1 or the two lower slide groove flanges 3b1 to avoid the problem of loosening.

[0040] In this embodiment, the unilateral positioning buckle 5 includes a unilateral buckle base plate 5a adapted to the two upper slide groove flanges 3a1 of the corresponding guide rail upper slide groove 3a and an end clip 5b integrally formed on the unilateral buckle base plate 5a. A second bolt through hole adapted to the locking bolt 7b is opened on the unilateral buckle base plate 5a. The screw portion of the locking bolt 7b passes through the second bolt through hole and is tightened in the threaded hole of the corresponding locking block 7a, so that the unilateral buckle base plate 5a is pressed against the two upper slide groove flanges 3a1 of the corresponding guide rail upper slide groove 3a from the outside to the inside, and the outer edge of the photovoltaic panel 2 at the end away from the adjacent photovoltaic panel 2 is clamped in the corresponding end clip 5b.

[0041] In this embodiment, the bilateral positioning buckle 6 includes a bilateral buckle base plate 6a adapted to the two upper slide groove flanges 3a1 of the corresponding guide rail upper slide groove 3a and two middle clips 6b integrally formed on the bilateral buckle base plate 6a. A third bolt through hole adapted to the locking bolt 7b is provided on the bilateral buckle base plate 6a.
