Detailed Description
The present invention is directed to overcoming the disadvantages of the prior art and providing a dual glass assembly with high conversion rate and long service life, and will be described in further detail with reference to the following embodiments.
Example 1
The dual-glass assembly with high conversion rate and long service life has two factors of influence, wherein one factor is the performance of the battery piece 101 forming the dual-glass assembly; secondly, the rate of sheltering from of dual glass assembly, let frame 2 shelter from dual glass assembly main part 1 as few as possible promptly. In this embodiment, the improvement of the conversion rate mainly utilizes the shielding dual glass assembly main body 1 with the frame 2 as less as possible.
The influence factor of the dual-glass assembly with long service life is two, one of the two factors is still the performance of the battery piece 101 forming the dual-glass assembly, and the other factor is that the dual-glass assembly is more stable to install. The solar cell sheet 101 constituting the dual glass assembly in the present embodiment is an N-type cell, which has a higher lifetime than a P-type cell. Then this embodiment designs dual glass assembly's mounting structure again for dual glass assembly installs the back stability higher.
Double glass assembly includes double glass assembly main part 1, frame 2, clamp plate 3, housing bolt 5, connects female mouthful, connects the pin thread.
As shown in fig. 3, the dual glass assembly main body 1 is formed by laminating a dustproof glass sheet 102, a battery sheet 101 and a dustproof glass sheet 102, as in the prior art. The glass sheet 102 and the battery sheet 101 are bonded by the EVA packaging adhesive 103, so that the strength is increased.
In this embodiment, for the convenience of the final solar photovoltaic array that forms of dual glass assembly's installation, consequently, dual glass assembly main part 1 is equipped with frame 2.
As shown in fig. 4, the frame 2 is a square frame 2 matched with the shape of the dual-glass assembly main body 1, four pressing plates 3 matched with the sides of the square frame 2 are arranged on the inner side of the square frame 2 respectively, and sealing strips 4 matched with the pressing plates 3 in size are arranged on the opposite surfaces of the pressing plates 3.
A pressing bolt 5 is fixedly connected to the back surface of each pressing plate 3. Specifically, the square frame 2 is provided with bolt holes, and the compression bolts 5 are fixedly connected with the compression plate 3 after penetrating through the bolt holes.
The position of the clamping plate 3 can be changed by the relative position of the clamping bolt 5 in the bolt hole. During the installation, place dual glass assembly between clamp plate 3, then screw up clamp bolt 5 for four clamp plates 3 tightly push down dual glass assembly main part 1. Thereby realizing the connection of the frame 2 and the dual-glass assembly main body 1. By adopting the structure, the sealing strip 4 is soft and does not damage the dual-glass assembly main body 1, and meanwhile, the uncured part of the EVA packaging adhesive 103 is prevented from overflowing. More importantly, this structure only is connected fixedly with four sides of dual glass assembly main part 1, and does not cover dual glass assembly main part 1's front and reverse side to do not shelter from it, make dual glass assembly can receive the area of sunshine as big as possible, thereby make the conversion rate uprise.
It is worth mentioning that in the present embodiment, three fastening bolts are uniformly arranged and connected to each of the pressure plates 3.
In this embodiment, be equipped with on frame 2 and connect public piece 6 and connect female 7, specific speaking, be equipped with on frame 2 every two corresponding one sides wherein and connect public piece 6, be equipped with on the opposite side and connect female 7.
The male connecting piece 6 comprises a male head, the outer wall of the male head is provided with threads, and the male head is provided with a connecting cylinder with threads on the inner wall. The threaded cylinder is rotatable relative to the male portion. The connecting female member 7 comprises a female head, and the outer wall of the female head is provided with threads.
When two dual glass assembly connect, the public head of the public piece 6 of connection of one of them dual glass assembly butts with the female head butt joint of the female 7 of connection of another dual glass assembly, then changes the position with the connecting cylinder rotation, rotates the connecting cylinder on the public head to between public head and the female head to realize the firm connection of matching of two dual glass assembly. Compare in prior art, through the structure of joint spare joint between two dual glass assembly, connect more stable. Simultaneously, it has better effect to be, when a plurality of dual glass assembly formed the solar photovoltaic array, if wherein arbitrary dual glass assembly takes place to be in the same direction as bad because of various reasons such as outside impact or internal circuit, through rotating the connecting cylinder to public overhead, alright take out this dual glass assembly from whole solar photovoltaic array, change new. Adopt traditional joint structure then need dismantle dual glass assembly in turn, it is very troublesome to change the maintenance.
The invention is well implemented in accordance with the above-described embodiments. It should be noted that, based on the above structural design, in order to solve the same technical problems, even if some insubstantial modifications or colorings are made on the present invention, the adopted technical solution is still the same as the present invention, and therefore, the technical solution should be within the protection scope of the present invention.
