Example 1:

referring to fig. 1-8, a photovoltaic panel includes a plurality of cell panels arranged in a rectangular array, with any intersection of four adjacent cell panels separated by a cross-shaped spacer 1; the intersection of any two adjacent battery panels is hermetically connected through a linear sealing element 2, and the linear sealing element 2 extends to the upper part of the cross-shaped positioning element 1; still include clamp plate 3, cross setting element 1 through the bolt 4 that passes clamp plate 3 and cross setting element 1 with the tip clamp fixation of the correspondence of a style of calligraphy sealing member 2, cross setting element 1 through the bolt 4 that passes clamp plate 3 and cross setting element 1 and the support 14 fixed connection of peripheral hardware.

Based on the limitation of the space of the drawing, the attached drawings of the embodiment only list the combination structure of 4 battery panels, in practical application, when the battery panel is used in a scene such as a roof, the battery panel generally has dozens or hundreds of battery panels, and the attached drawings do not represent the limitation of the protection scope of the scheme.

In the installation, cross setting element 1 is placed at the intersection of four adjacent battery panels of arranging, the right angle portion location of battery panel is in the right angle of cross setting element 1's correspondence, then with the intersection of 2 sealing connections of a style of calligraphy sealing member 2 at arbitrary two adjacent battery panels, press clamp plate 3 in the top of cross setting element 1, then insert bolt 4, realize the end fixing of a style of calligraphy sealing member 2 with the locking of cross setting element 1 and clamp plate 3, the fixed of the corner of battery panel has also been realized simultaneously.

It should be noted that: there are many ways in which the in-line seal 2 sealingly connects two battery panels, for example by means of grooves 7 and sealing ribs 8 as described below; the straight-line sealing element 2 and the battery panel can be connected by glue or other sealing connection modes. In the present embodiment, the in-line sealing member 2 is used only for sealing two adjacent battery panels, and does not serve as a fixed connection. The fixed connection is realized by locking the pressure plate 3, the end part of the linear sealing element 2, the corner of the battery panel and the cross-shaped positioning element 1 on the external bracket 14 through the bolts 4.

In the present embodiment, the cross-shaped positioning member 1 plays a positioning role, and it is conceivable that it should be made of a hard material, such as aluminum alloy, hard plastic, stainless steel, etc. The platen 3 is preferably made of a metal material such as aluminum alloy or stainless steel.

Implicitly, the center of the cross-shaped positioning element 1 needs to have a hole for the bolt 4 to pass through, and the hole can be a smooth hole or a threaded hole, preferably a threaded hole, which is matched with the bolt 4. At the same time, the pressure plate 3 should also have holes through which the bolts 4 pass.

In the present embodiment, the battery panel refers to a battery panel based on solar power generation.

In this embodiment, the battery panel include panel 5 and fix frame 6 around panel 5, the edge of frame 6 be equipped with recess 7, the both sides of the lower surface of a style of calligraphy sealing member 2 be equipped with the recess 7 complex sealed sand grip 8 that corresponds.

The linear seal 2 is sealingly connected by the sealing bead 8 engaging in the groove 7. Of course, a convex strip may be provided on the edge of the frame 6, and a concave groove 7 may be optionally provided on the lower surface of the linear seal 2.

More specifically, the frame 6 is a rectangular structure formed by sequentially connecting four aluminum alloy sections 9 at the head; a clamping part 10 for clamping the edge of the battery panel 5 and a lightening hole 11 arranged in the aluminum alloy section 9 are arranged in the aluminum alloy section 9; the groove 7 is arranged on the upper surface of the aluminum alloy section bar 9.

The connection of two adjacent aluminum alloy profiles 9 can be selected as welding or other connection methods, for example, the connection of two adjacent aluminum alloy profiles 9 is realized through a right-angle corner brace which can be snapped into the lightening hole 11, which is not the main point of the present embodiment and is not limited to this embodiment.

The above-described design of the frame 6 makes it possible to facilitate the assembly of the battery panel and to reduce the weight.

Preferably, the lightening holes 11 extend along the length direction of the aluminum alloy section bar 9 and are positioned right below the grooves 7.

In order to further improve the sealing and clamping stability of the battery panel 5 and the frame 6, the upper and lower surfaces of the clamping portion 10 are provided with at least one rib 12, in this embodiment, two ribs 12 are arranged side by side.

In this embodiment, the photovoltaic panel is integrally fixed through the above design, if the assembly is not accurate enough, the intersection position of the pressing plate 3 and the linear sealing element 2 may still have poor sealing, and in order to solve the problem, a sealing gasket ring 13 is arranged between the pressing plate 3 and the linear sealing element 2. It will be appreciated that the gasket ring 13 should be made of a soft material for sealing, such as silicone rubber or the like. The gasket ring 13 is pressed by the bolts 4 over the end of the in-line seal 2.

Example 2

Specifically, the support 14 is composed of criss-cross support rods; the support rod is positioned right below the intersection of the two adjacent battery panels and is used for supporting the frame 6 of the two adjacent battery panels.

The present embodiment has the following advantages:

1. no additional fixation is required on the linear sealing member 2 because the linear sealing member 2 is not required to play a role in fixing the adjacent two battery panels. In this embodiment, the pressing plate 3, the end portion of the linear sealing member 2, the corner of the battery panel, and the cross-shaped positioning member 1 are locked on the bracket 14 by the bolts 4, so that the structure is simple, and the fixing effect is good.

2. No matter whether this embodiment is to tear open or adorn all conveniently, if arbitrary battery panel needs to be changed, then only need loosen bolt 4 on four angles that this panel corresponds, can take off battery panel, and in traditional structure, will change arbitrary battery panel, generally will realize the dismantlement of large tracts of land battery panel.

3. The present embodiment does not need too complicated supporting structure, and only needs the bracket 14 to realize the integral fixation of the plurality of battery panels, which has the advantages of simplifying the structure and avoiding the influence of too complicated supporting structure on the indoor lighting. Since the panel 5 of the present embodiment may be not only the conventional panel 5 but also the high-transmittance solar panel 5, in the case of using the high-transmittance solar panel 5, the support mechanism should be simplified to facilitate indoor lighting.

The above embodiments are preferred embodiments of the present invention, but the embodiments of the present invention are not limited to the above embodiments, and any other changes, modifications, substitutions, combinations, and simplifications which do not depart from the spirit and principle of the present invention should be equivalent replacement modes, and all are included in the scope of the present invention.
