[0002] Photovoltaic corrugated sheets are a new type of building material that combines photovoltaic technology with corrugated structure. They have both the structural characteristics of corrugated sheets and the power generation function of photovoltaic modules. Photovoltaic corrugated sheets have a wavy corrugated structure, which gives them good mechanical properties, such as high strength and impact resistance. At the same time, the corrugated structure can also increase the surface area of ​​the sheet and improve the heat dissipation effect of photovoltaic modules.

[0003] In the prior art, the authorized announcement number CN201695587U solar power corrugated board cannot fully utilize the limited space on the top of the building, and the installation is complicated. At the same time, the direction of sunlight determines the power generation efficiency. This product consists of: a corrugated board (2), on which an aluminum substrate (4) is connected by a bio-adhesive (3), and the aluminum substrate has a polycrystalline silicon substrate (5).

[0004] To facilitate the transportation and storage of photovoltaic (PV) corrugated panels, as well as their assembly and disassembly, the overall volume of PV corrugated panels is limited. Therefore, large-scale installations require two PV corrugated panels to be butt-to-buttoned together. Currently, most PV corrugated panels are fixed using screws or bolts, with adjacent panels directly touching and butt-to-button. This method reduces the sealing of the connection or butt joint and affects the practicality of the PV corrugated panels. Utility Model Content

[0026] This utility model provides a sealing and docking device for connecting photovoltaic corrugated sheets.

[0027] Example 1, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The device includes a main body 1, with two sets of sliding grooves 2 at one end. The top of the sliding grooves 2 is formed with linearly distributed moving grooves 3. The top of the moving grooves 3 is provided with a through slot 4. A sliding rod 5 is slidably connected inside the sliding grooves 2. The top of the sliding rod 5 is fixedly connected with a linearly distributed L-shaped pin 6.

[0033] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4Two sets of plates 9 are clamped between the lower clamping plate 801 and the upper clamping plate 802. The plates 9 include flat plates 901 and corrugated strips 902 arranged in a linear array. The flat plates 901 are fixedly connected between two corresponding corrugated strips 902. Corrugated strips 902 have through-hole fixing holes at the corresponding positions of each bolt 803.

[0034] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 The upper part of the device body 1 has side grooves arranged in a linear array on both sides. The bottom wall inside the side grooves has through-hole three fixing holes, and bolts 2 11 are installed in the fixing holes three.

[0035] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 A sealing plate 12 is clamped between the upper clamping plate 802 and the plate body 9, between the plate body 9 and the lower clamping plate 801, and between the lower clamping plate 801 and the device body 1. A through hole is provided at the corresponding position of the sealing plate 12 relative to the bolt 803.

[0036] Specifically, the sealing plate 12 is made of EPDM rubber, which has good weather resistance, ozone resistance and waterproof performance, and can effectively prevent moisture and dust from entering the connection parts.

[0037] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 One end of the slide bar 5 is provided with a threaded groove, and a threaded rod 13 is threadedly connected in the threaded groove. The end of the threaded rod 13 away from the slide bar 5 is fixedly connected to a rotating rod 14, which is rotatably connected inside the slide groove 2.

[0038] Specifically, the rotating rod 14 is rotatably connected to the inside of the slide groove 2 via a sealed bearing.

[0039] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 An aluminum substrate 15 is mounted on the top of the flat panel 901, and a polycrystalline silicon substrate 16 is disposed on the top of the aluminum substrate 15. A lead box 17 is disposed at the bottom of the corrugated strip 902.

[0040] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 The top of the polycrystalline silicon substrate 16 is coated with a transparent resin layer;

[0041] Specifically, the panel 9 is a photovoltaic corrugated board. The panel 9, aluminum substrate 15, polycrystalline silicon substrate 16 and lead box 17 are all existing technology equipment or structures. Their specific forms, usage methods and installation methods are all existing technology means, and this application will not elaborate on them. The installation position of the lead box 17 can also be introduced into the room or other locations below the photovoltaic corrugated board, depending on the actual situation.

[0042] Working principle: When using the photovoltaic corrugated plate connection sealing docking device, firstly, use bolt 2 11 to fix the device body 1 to the roof or other places where photovoltaic corrugated plates need to be installed. Then, align the ends of the two sets of plates 9 and place them at the bottom of the upper clamping plate 802 and the top of the lower clamping plate 801. At this time, the bottom end of bolt 1 803 on the upper clamping plate 802 passes through the corresponding fixing hole 1 on the lower clamping plate 801. Then, use nut 804 threadedly sleeved on the end of bolt 1 803, and use the nut 804 and the nut on bolt 1 803 to clamp the upper clamping plate 802 and the lower clamping plate 801, and make the upper clamping plate 802 and the lower clamping plate 801 clamp the two sets of plates 9.

[0043] After the clamping and fixing component 8 is fixed, it is installed on the device body 1, so that the insert plate 7 on the clamping and fixing component 8 is inserted into the corresponding slot 4. At this time, the insertion hole on the insert plate 7 is aligned with the pin head of the L-shaped pin 6. By rotating the rotating rod 14, the rotating rod 14 uses the threaded rod 13 to drive the sliding rod 5 to slide in the sliding groove 2, and uses the sliding rod 5 to drive the L-shaped pin 6 to slide in the moving groove 3, so that the pin head of the L-shaped pin 6 passes through the insertion hole on the insert plate 7, thus completing the docking and fixing of the clamping and fixing component 8 and the device body 1.
