[0023] The utility model will be further explained in detail in combination with the drawings and the embodiment of the utility model.

[0024] Figures 1 to 4 One embodiment of the utility model BIPV guide rail type water guide support structure is shown, including water guide groove 1 and support frame 2, the cross section of water guide groove 1 is inverted trapezoidal that is big on the top and small on the bottom, the bottom wall of water guide groove 1 is inwardly bent, the guide rail 11 extending along the longitudinal direction is formed in the inner wall of the groove bottom, the guide groove 12 extending along the longitudinal direction is formed in the outer wall of the groove bottom, and the cross section of guide rail 11 and guide groove 12 is all "T" type; support frame 2 includes vertical plate 21, connecting plate 22, bottom plate 23, top plate 24 and recess 25, two vertical plates 21 are arranged in parallel, connecting plate 22 is connected with vertical plate 21 perpendicularly and forms "H" type support with two vertical plates 21; two bottom plates 23 are respectively fixed on the bottom of two vertical plates 21 and are parallel to each other, so that the lower part of "H" type support with bottom plate 23 is nested with guide rail 11; two top plates 24 are respectively fixed on the top of two vertical plates 21 and are parallel to each other, and top plate 24 is used for installing photovoltaic plate frame; recess 25 is fixed between two top plates 24 and is used for installing cover plate between photovoltaic plates.

[0025] The specific use process of the embodiment of BIPV guide rail type water guide support structure is as follows:

[0026] Water guide groove 1 is fixed on the support of BIPV, multiple support frames 2 are nested into water guide groove 1 from one end of guide rail 11 in water guide groove 1, the position is adjusted by sliding, so that multiple support frames 2 are fixed at intervals along guide rail 11, then the frame of photovoltaic plate is fixed on top plate 24 through screw hole, two top plates 24 respectively support and fix two adjacent photovoltaic plates, then the cover plate is pressed between the frames of adjacent photovoltaic plates, so that the cover plate is nested with recess 25, and the water falling from the gap between the frames of adjacent photovoltaic plates into water guide groove 1 can be smoothly guided out when it rains.

[0027] AsFigure 1 As shown, the BIPV guide rail type water guiding support structure of this embodiment is based on a "U"-shaped water guiding channel, inheriting the advantages of the "U"-shaped water guiding channel, such as simple structure, easy processing, low material consumption, and large water guiding capacity. A guide rail 11 is formed inside the channel bottom through a bottom bending structure, and a guide groove 12 is formed outside the channel bottom. An "H"-shaped bracket with a base plate 23 is designed so that the lower part of the "H"-shaped bracket and the base plate 23 are nested with the guide rail 11. When installing the support frame 2, it is only necessary to nest the support frame 2 into the water guiding channel 1 from one end of the guide rail 11, and it can slide along the guide rail 11 to adjust any position, making installation and disassembly very convenient. Because the base plate 23 is embedded from both sides into the waist side of the "T"-shaped guide rail 11 (e.g., Figure 2 As shown at point A, the guide rail 11 vertically engages with the support frame 2, ensuring a very secure vertical connection. Therefore, using the guide rail 11 in conjunction with the support frame 2 to install photovoltaic panels provides strong wind resistance. The "H"-shaped bracket structure formed by the vertical plate 21 and the connecting plate 22 is relatively stable, while the two bottom plates 23 further enhance the stability of the support frame 2. The groove 25 and top plate 24 fixed to the top of the "H"-shaped bracket further strengthen the overall mechanical strength and structural stability of the support frame 2. The groove 25 at the top of the support frame 2 is used to install the cover plate between the photovoltaic panel frames, reducing water entry into the water channel 1 between the photovoltaic panels, lowering the drainage pressure, and achieving multi-level waterproofing. It is worth emphasizing that, since the bottom of the water guide channel 1 has a "T"-shaped guide groove 12, the guide groove 12 can be used for nesting and fixing. That is, the support beam of the existing bracket is improved by designing a guide beam that nests and cooperates with the guide groove 12 on the support beam to further improve the installation convenience, firmness and wind resistance of the water guide channel 1 in this embodiment.

[0028] Specifically, a guide beam (not shown in the figure) is longitudinally arranged on the upper surface of the support beam. The guide beam has a "T" shaped cross-section and is nested with the guide groove 12. During installation, the support beam is fixed to the BIPV bracket, which can replace the original beam structure or the support beam can be directly added. Then, the water guide groove 1 is nested with the "T" shaped guide beam from one end. Installation and disassembly are very convenient, without the need for screws or drilling, effectively avoiding the risk of leakage. Due to the snap-fit ​​effect of the "T" shaped structure, the two also have a reliable connection in the vertical direction. Therefore, in this embodiment, the double "T" shaped structure nesting cooperation between the support frame 2 and the guide rail 11, and the guide groove 12 and the guide beam, greatly improves the convenience, reliability and wind resistance of installation.

[0029] Of course, in other embodiments, the water channel can also be fixed on the BIPV bracket using a bolt and nut assembly whose size matches the "T"-shaped structure of the guide groove 12. That is, the "T"-shaped structure of the guide groove 12 is used as the fixing position of the bolt on the water channel 1, without drilling holes in the water channel 1, effectively avoiding the risk of water leakage.

[0030] As Figure 3 , Figure 4 shown in the embodiment, the opening end of the groove 25 is higher than the upper surface of the top plate 24, and the high part is used for positioning and limiting the relative position of the photovoltaic panel frame and the top plate 24 in the horizontal plane, and can quickly and accurately reserve the installation position of the cover plate, so that the installation is simple and convenient.

[0031] In the embodiment, the edge of the top plate 24 extends outside the vertical plate 21, and the extended part can be matched with the photovoltaic panel frame and the top plate 24 to be installed by using a pressing block assembly, so that the installation mode is diversified, and the convenience of use is improved.

[0032] In the embodiment, the end of the top plate 24 connected with the groove 25 extends out of the inner wall of the groove 25, and the extended part is used for supporting the cover plate from the vertical direction.

[0033] In the embodiment, a secondary water guide groove is also included, and in the assembled state, the secondary water guide groove is vertically lapped with the water guide groove 1, the opening end of the water guide groove 1 is provided with an outwardly folded edge 13, and the port of the secondary water guide groove is lapped on the folded edge 13. The secondary water guide groove is used for horizontal water guide, and the water guide groove 1 is used for longitudinal water guide and collects water in the secondary water guide groove.

[0034] In the embodiment, a plurality of adhesive clamping parts are installed on the bottom of the water guide groove 1 along the longitudinal direction of the groove body, which are used for clamping and fixing the position of the support frame 2, so that the position of the support frame 2 is fixed during installation and use, and the disassembly and assembly are convenient.

[0035] In the embodiment, the water guide groove 1, the support frame 2, the guide beam and the secondary water guide groove are integrally formed. The integrally formed structure is simple and convenient to process.

[0036] In the embodiment, the guide beam is made of steel structure; the water guide groove 1, the support frame 2 and the secondary water guide groove are made of aluminum alloy material, and the aluminum alloy material can meet the requirements of strength, corrosion resistance and light weight of the BIPV guide rail type water guide support structure in the embodiment. Of course, in other embodiments, stainless steel or special steel material can also be used.
