All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0028] Please refer to Figures 1-5 , the present invention provides a technical solution: a connecting mechanism between a flexible photovoltaic module and a large membrane structure environmental protection silo, including:

[0029] A steel skeleton 1 and a photovoltaic panel 2 arranged on the top of the steel skeleton 1;

[0030] And a photovoltaic frame 3 installed on the surface of the photovoltaic panel 2;

[0031] A steel strand 4 installed on the top of the steel skeleton 1;

[0032] An installation mechanism 5 for connecting the frame of the photovoltaic panel 2 is installed on the surface of the steel strand 4;

[0033] The installation mechanism 5 is a fixed metal member installed on the surface of the steel strand 4, and the photovoltaic frame 3 and the photovoltaic panel 2 are adhesively bonded by a butyl tape.

[0034] The photovoltaic panel 2 fits into the surface groove of the photovoltaic frame 3;

[0035] In this embodiment, the photovoltaic panel 2 is a lightweight and flexible photovoltaic module (SMF520J-12*12UW), with a module size of 22451*11952*2mm. The photovoltaic frame 3 and the photovoltaic panel 2 are adhesively bonded by a butyl tape 9. At the same time, the photovoltaic frame 3 is directly pasted above the membrane material 10 with the butyl tape 9. The distance between the photovoltaic panels 2 is 50mm, and the maintenance passage is 5100mm. It needs to be cleaned regularly. Before cleaning, it is necessary to check whether there is abnormal power output, analyze whether it is caused by leakage, and check whether the connecting wires and related components of the module are damaged or adhered; before cleaning, use a test pen to test the module support to eliminate the danger of electric leakage and ensure personal safety. In this project, the flexible photovoltaic panel 2 is washed by drones and unmanned vehicles.

[0036] The photovoltaic frame 3 and the photovoltaic panel 2 are adhesively bonded by a butyl tape 9;

[0037] Main truss upper chords 11 are installed on both sides of the top of the steel skeleton 1, and the main truss upper chords 11 are connected to the steel strands 4 through assembly parts 12;

[0038] Furthermore, the upper chord 11 of the main truss is connected to the steel strand 4 by means of a mounting member, so that replacement and maintenance operations are facilitated.

[0039] The assembly part 12 is a welded node plate 121 installed on the surface of the steel strand 4, and a prestressed anchor 122 connected to the steel strand 4 is installed on one side of the welded node plate 121;

[0040] Among them, in the truss structure, steel plates welded on the columns are bolted to the beams, and the node plates are connecting structural components to ensure the stability and integrity of the entire structure.

[0041] A plurality of ventilation pads are installed on the back of the photovoltaic panel 2;

[0042] A membrane material 10 is installed between the bottom of the butyl tape 9 and the top of the steel frame 1;

[0043] Specifically, the film material 10 is used as a building material with functions such as heat insulation, waterproofing, and moisture-proofing, and the film material 10 has the characteristics of lightness, flexibility, and weakness.

[0044] The distance between the photovoltaic panel 2 and the surface of the film material 10 is kept at least 50 mm;

[0045] The steel strand 4 is arranged as a prestressed steel strand;

[0046] Specifically, steel strand is a metal product made of multiple steel wires twisted together, which has the characteristics of high strength, good flexibility and strong corrosion resistance.

[0047] The number of steel wires in the steel strand 4 is 7;

[0048] Among them, prestressed steel strands can be divided into many types according to the number of steel wires. Among them, 7-wire steel strands have unique advantages. The 7-wire structure enables the steel strands to evenly distribute the load when stressed, improving the stability of the overall structure. The construction of 7-wire prestressed steel strands is relatively simple and can be flexibly cut and installed according to project needs. At the same time, its good flexibility and plasticity also make it easy to bend and adjust at the construction site.

[0049] In this device, the photovoltaic frame 3 and the photovoltaic panel 2 are adhesively bonded by butyl tape 9. At the same time, the photovoltaic frame 3 is directly pasted above the membrane material 10 using butyl tape 9. The distance between the photovoltaic panels 2 is 50 mm, and the maintenance passage is 5100 mm. The connection and loading / unloading between the flexible photovoltaic module and the steel pipe truss are relatively convenient, and the installation is more firm. It needs to be cleaned regularly. Before cleaning, it is necessary to check whether there is abnormal power output, analyze whether it is caused by leakage, and check whether the connecting wires and related components of the module are damaged or adhered. Before cleaning, use a test pen to test the module support to eliminate the danger of electric leakage and ensure personal safety. In this project, the flexible photovoltaic panel 2 is washed by drone and vehicle.
