Example one

Referring to fig. 1 to 4, a waterproof cover plate 1 for a photovoltaic support is installed between adjacent photovoltaic modules 2, and a module frame 21 is arranged at the edge of each photovoltaic module 2, the waterproof cover plate 1 includes a cover plate body 10, the lower side of the cover plate body 10 is provided with two fixing edges 12 which extend downwards and are arranged side by side in the left and right sides, a telescopic gap is arranged between the two fixing edges 12, and the outer side of each fixing edge 12 is provided with a fixing tooth opening 121 fixed with the module frame 21.

After the technical scheme is adopted, when the waterproof cover plate 1 is installed, the two fixing edges 12 of the waterproof cover plate 1 are inserted into the gap between the adjacent photovoltaic modules 2, and the two fixing edges 12 are provided with the telescopic gap, so that the two fixing edges can elastically deform, and the waterproof cover plate can be suitable for the condition that the gap between the adjacent photovoltaic modules is changed; after the two fixing edges 12 elastically deform, the generated acting force fixes the fixing tooth openings 121 to the side of the assembly frame 21, so as to realize the fixed connection between the waterproof cover plate 1 and the assembly frame 21. And because need not to cooperate briquetting or other fasteners to install, consequently compare with prior art, it is convenient to install, and application scope is wide, has reduced installation and use cost.

It will be understood that the number of the fixing teeth 121 may vary, and two fixing teeth 121 are illustrated in the figure along the extension of the fixing edge 12, but only one fixing tooth may be provided, or three or more fixing teeth may be provided.

The cross-sectional shape of the fixing tooth mouth illustrated in the drawings is an isosceles triangle, but it is understood that the cross-sectional shape may also be a right triangle, an isosceles trapezoid, or a continuous sawtooth shape, and many variations thereof are possible and are not listed here.

The waterproof cover plate 1 is not only laterally fixed with the assembly frame 21 through the fixing edge 12, but also limits the downward position and ensures sufficient structural strength, therefore, the cover plate body 10 comprises a top 101 and a reinforcing edge 102 obliquely extending from the edges of the left and right sides of the top 101 to the lower side of the side, wherein the top 101 horizontally extends as a flat plate, the inner side of the reinforcing edge 102 is connected with a supporting edge 11 extending inwards and connected with the fixing edge 12, and the supporting edge 11 is used for supporting the upper surface of the assembly frame 21. Compress tightly waterproof apron 1 downwards, when fixed limit 12 is fixed with subassembly frame 21 side, support limit 11 pressfitting in the upper surface of subassembly frame, waterproof apron can't continue to push down, accomplishes the installation of waterproof apron this moment promptly. Wherein support 11 level extensions on limit, fixed limit 12 vertical extension, consequently support 11 and fixed limit 12 perpendicular, confirmed the mounted position of waterproof apron through supporting 11 and the cooperation of fixed limit 12 on limit, guarantee connection structure stability between waterproof apron and the photovoltaic module.

Because the reinforcing edge 102 extends obliquely to the lower side of the side face, water on the surface of the waterproof cover plate can flow onto the photovoltaic module along the oblique face, and the light of the photovoltaic module is prevented from being shielded. Similarly, in order to avoid blocking the illumination of the photovoltaic module, the height of the reinforcing edge 102 may be set to be lower, for example, lower than 2cm, and specifically, 1.5cm, 1cm, and the like may be selected.

The waterproof cover plate is used for not only blocking the gap between the adjacent photovoltaic modules above, but also preventing water from leaking into the gap between the adjacent photovoltaic modules from the side surface of the waterproof cover plate. For this purpose, a sealing notch 111 can be provided in the support edge 11, which is sealingly connected to the upper surface of the module frame. In addition, the cover plate body 10 may further include a waterproof outer brim 103 extending continuously in the extending direction of the reinforcing rim 102. As shown in fig. 4, the sealing tooth openings 111 seal the supporting edge 11 and the upper surface of the assembly frame 21, the edge of the assembly frame 21 is shielded by the waterproof outer eaves 103, so that rainwater is prevented from entering the inner side of the waterproof cover plate, and the waterproof edge are combined with each other, so that the waterproof effect is enhanced, and the waterproof performance is better.

Since the fixing edge 12 needs to be elastically deformed and the other portions need to secure sufficient strength, the fixing edge may have a relatively thin thickness. In this embodiment, the top portion 101, the reinforcing edge 102, the waterproof outer eaves 103, and the supporting edge 11 have the same thickness, and are greater than the thickness of the fixing edge 12. For example, the top 101, the reinforcing edge 102, the waterproof outer eaves 103 and the supporting edge 11 shown in fig. 2 are all 3.6mm, and the thickness of the reinforcing edge 102 is greater than that of the fixing edge 12, for example, the thickness of the fixing edge 12 shown in fig. 2 is 2.4mm.

It is understood that the cover body may be changed into other shapes, and of course, the support edge may not be separately provided, but a structure with similar functions may be directly provided on the cover body.

A plurality of photovoltaic modules of the large-scale photovoltaic system are arranged in a matrix mode, the photovoltaic modules are large in area and large in quantity after being combined, and the corresponding waterproof cover plates needing to be installed are also large in quantity. Therefore, in order to guarantee the uniformity of installation, the upper surface of top 101 corresponds the midline position and is equipped with the installation and compares tooth mouth 1011, and two fixed edges 12 set up in the installation and compare tooth mouth 1011 bilateral symmetry, and the installation also corresponds the intermediate position in clearance between adjacent photovoltaic module's the subassembly frame with comparing tooth mouth 1011, and the installation is compared tooth mouth 1011 and can be provided the vision contrast when the installation, guarantees waterproof cover plate installation uniformity.

In addition, can also refer to current common waterproof apron of aluminum alloy, for example, waterproof apron can adopt the aluminum alloy material to make, and waterproof apron can design as an organic whole extrusion structure. The waterproof adhesive is made of aluminum alloy materials, has excellent corrosion resistance, has stronger ageing resistance and longer service life compared with the traditional waterproof adhesive and waterproof adhesive tape. The mature extrusion forming process is adopted for mass production, so that the cost is lower.
