[0004] As for the above-mentioned tile-type photovoltaic module installation structure, it is obvious that its structure is very complicated and it is also difficult to install. Summary of the invention

[0006] The technical solutions to the above technical problems are as follows:

[0007] The mounting structure of a non-frame photovoltaic module includes a load-bearing frame, which is composed of multiple cross beams and multiple longitudinal beams, and is characterized in that a limiting component with a step at the upper end is fixed on each cross beam, and multiple supporting devices for carrying the non-frame photovoltaic module are fastened on each longitudinal beam.

In addition, when assembling the non-frame photovoltaic assembly, the mounting structure of the present invention only needs to insert one longitudinal side of the non-frame photovoltaic assembly into the first space between the first support platform and the first pressure plate, and the other longitudinal side into the second space formed by the second support platform and the first pressure plate, and then apply the corresponding sealing strip for sealing. Therefore, not only is its own structure simple, but the installation process is also very simple. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] A non-frame photovoltaic module 100 . DETAILED DESCRIPTION

[0016] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0017] The mounting structure of the non-frame photovoltaic module includes a load-bearing frame, which is composed of a plurality of cross beams 1 and a plurality of longitudinal beams 2. A limiting component 3 with a step at the upper end is fixed on each cross beam 1. The limiting component 3 preferably adopts a hollow structure. The side of the non-frame photovoltaic module 100 extending along the horizontal direction of the load-bearing frame abuts against the step of the limiting component 3 and is limited by the step. In this way, each non-frame photovoltaic module 100 is supported and limited by the limiting component 3 in the longitudinal direction of the load-bearing frame.

[0018] A plurality of supporting devices for supporting the non-frame photovoltaic components are fastened on each longitudinal beam 2, and the supporting devices include a bottom plate 4 with two ends extending longitudinally along the supporting frame, a first boss 5 is provided in the middle of the first end of the bottom plate 4, and first pressure plates 5a extending transversely along the supporting frame are respectively provided on the two side walls of the upper part of the first boss 5, and the parts of the bottom plate 4 located on both sides of the first boss 5 are areas for supporting the non-frame photovoltaic components 100, and a first supporting platform 6 and a second supporting platform 7 are provided in this area, and the first supporting platform 6 and the second supporting platform 7 respectively extend longitudinally along the supporting frame. The distance between the first support platform 6 and the first boss 5 is smaller than the distance between the second support platform 7 and the first boss 5, and the first support platform 6 and the second support platform 7 are respectively located directly below the first pressure plate 5a. Therefore, a first space 6a for accommodating the side of the non-frame photovoltaic component 100 extending along the longitudinal direction of the supporting frame is formed between the first support platform 6 and the first pressure plate 5a, and a second space 7a for accommodating the side of the non-frame photovoltaic component 100 extending along the longitudinal direction of the supporting frame is formed between the second support platform 7 and the first pressure plate 5a. Obviously, the volume of the first space 6a is smaller than the volume of the second space 7a.

[0019] Based on the above design, when the two side edges of the non-frame photovoltaic component 100 extending longitudinally along the supporting frame are embedded in the bottom plate 4 located on two adjacent longitudinal beams 2, one side edge of the non-frame photovoltaic component 100 extending longitudinally along the supporting frame is embedded in the first space 6a on the one bottom plate 4, and when the other side edge of the same non-frame photovoltaic component 100 extending longitudinally along the supporting frame is embedded in the second space 7a on the other bottom plate, the other side edge of the non-frame photovoltaic component 100 can be embedded in the second space 7a first. In this way, when the one side edge of the non-frame photovoltaic component 100 is embedded in the first space 6a, the second space 7a can form a giving way effect, so it is conducive to quickly embedding the non-frame photovoltaic component 100 in the bottom plate 4 located on two adjacent longitudinal beams 2.

[0020] One end of the first boss 5 extends longitudinally along the supporting frame to the outside of the bottom plate 4 to form a first outer extension portion 8, a first step 9 is formed at the lower end of the first outer extension portion 8, a second boss 10 located on the inner side of the bottom plate 4 is provided in the middle of the second end of the bottom plate 4, a second step 11 is formed at the upper end of the second boss, the first end and the second end on each bottom plate 4 are two opposite ends on the bottom plate 4, and the first end and the second end are the ends of the bottom plate 4 in the longitudinal direction of the supporting frame, respectively. In the adjacent two supporting devices on the same longitudinal beam 2, after the first end of one bottom plate overlaps the second end of the other bottom plate, the first step 9 on the first outer extension portion 8 is embedded in the second step 11, so that a step is formed between the two adjacent supporting devices, so that the ends of two adjacent non-frame photovoltaic modules 100 installed on the two adjacent supporting devices overlap in an imbricate manner. Since the non-frame photovoltaic module 100 is in an inclined state as a whole after being installed on the supporting frame, when water reaches the surface of the non-frame photovoltaic module 100, the water flows along the surface of the non-frame photovoltaic module 100. Since the ends of two adjacent non-frame photovoltaic modules 100 overlap in a shingle-like manner, when water flows from the upper non-frame photovoltaic module 100 to the next non-frame photovoltaic module 100, the water will not penetrate into the back of the non-frame photovoltaic module 100 from the overlapping gap between the two non-frame photovoltaic modules 100. The other end of the first boss 5 and one end of the second boss 10 are extended longitudinally along the supporting frame and combined into one. The two side walls of the upper part of the second boss 10 are respectively provided with second pressing plates 10a extending laterally along the supporting frame.

[0021] A first water guide groove 6b extending along the longitudinal direction of the supporting frame is provided on the first support platform 6, and a second water guide groove 7b extending along the longitudinal direction of the supporting frame is provided on the second support platform 7. Since the ends of two adjacent supporting devices on the same longitudinal beam overlap, the first water guide grooves 6b on the two adjacent supporting devices are interconnected, and the second water guide grooves 7a on the two adjacent supporting devices are interconnected. Therefore, when rainwater reaches the uppermost position of the supporting frame, the first water guide groove 6b and the second water guide groove 7b can be respectively guided to the lowermost end of the supporting frame to avoid the accumulation of rainwater affecting the non-frame photovoltaic module 100.

[0022] The first support platform 6 and the second support platform 7 are both provided with a vibration-damping strip 12, the cross section of which is an I-shaped strip, the first water guide groove 6b is provided with a first limiting portion located at the notch, and the second support platform 7 is provided with a second limiting portion located at the notch, a portion of the vibration-damping strip 12 installed on the first support platform 6 is located at the upper end of the first support platform 6, and the other end is embedded in the first water guide groove 6b, and the vibration-damping strip 12 is limited by the first limiting portion. A portion of the vibration-damping strip 12 installed on the second support platform 7 is located at the upper end of the second support platform 7, and the other end is embedded in the second water guide groove 7b, and the vibration-damping strip 12 is limited by the second limiting portion.
