Detailed Description

In order that the present invention may be more readily and clearly understood, the following detailed description of the present invention is provided in connection with the accompanying drawings.

Example 1:

referring to fig. 1, the present embodiment provides a photovoltaic cell module, including: photovoltaic unit 1, connecting piece group and concatenation group.

In detail, the photovoltaic unit 1 of the present embodiment employs a square structure, as shown in the drawings. Of course, the photovoltaic unit 1 herein may be equivalently evolved and replaced by a rectangular structure, and the present embodiment is only exemplified by the case of the photovoltaic unit 1 having a square structure.

The connecting piece group comprises four connecting blocks 2 which are rectangular structural bodies and are respectively convexly arranged on four side end faces of the photovoltaic unit 1, the length of each connecting block 2 is equal to that of each side end face of the photovoltaic unit 1, under an optional implementation condition, the thickness of each connecting block 2 is equal to that of the photovoltaic unit 1, and the front faces of the connecting blocks 2 are flush with the front faces of the photovoltaic units 1. That is, the connection block 2 here forms a hemming structure for the side end faces of the photovoltaic unit 1. Since the length of each connecting block 2 is equal to the length of the side end face of the photovoltaic unit 1, an L-shaped end angle is formed between each two adjacent connecting blocks 2.

Furthermore, the splicing group comprises four splicing plates 3 which are connected between every two adjacent connecting blocks 2 and are respectively positioned at the L-shaped end corners of the photovoltaic units 1 and have the same size; the four splice plates 3 are all square structural bodies; the center of each splice plate 3 is provided with a plug-in hole 5. In particular, the splice plates 3 herein not only form the connection between every two adjacent connector blocks 2 to improve the firmness of the overall connector block group structure and the service life in the use state. The splicing plate 3 also has a splicing function in the splicing process of a plurality of photovoltaic cell modules, and the specific content of the part is described in embodiment 2.

It should be further noted that, for the splice plates 3 of the present embodiment, the side length of each splice plate 3 is equal to twice the width of the joint block 2. On the basis of the structure, every two adjacent splicing plates 3 are staggered to be positioned on different horizontal planes; and every two adjacent splicing plates 3 are positioned on the same horizontal plane. Like this at two adjacent photovoltaic cell modules at the in-process of assembling, the horizontal concatenation is realized to connecting block 2 of two adjacent photovoltaic cell modules, thereby splice plate 3 between the adjacent terminal surface of two adjacent photovoltaic cell modules can fold and press the concatenation to realize that the concatenation between the photovoltaic cell modules links to each other this moment.

In an alternative embodiment, the sum of the thicknesses of the two splice plates 3 is smaller than the thickness of the photovoltaic unit 1. In the process of splicing and connecting two adjacent photovoltaic cell modules, the whole thickness of the splicing plate 3 between the adjacent end surfaces of the two adjacent photovoltaic cell modules after being laminated is smaller than that of the photovoltaic unit 1.

Example 2:

referring to fig. 1 to 3, on the basis of the photovoltaic cell module of embodiment 1, the present embodiment provides an assembled solar photovoltaic panel structure, including: the photovoltaic cell module is suitable for splicing a plurality of photovoltaic cell modules which are connected and have the same specification and size in the embodiment 1, and the connecting block 6 is suitable for being connected with the splicing plates 3 of every two adjacent photovoltaic cell modules in a matched and connected mode through the through splicing holes 5 after being stacked one by one.

It should be noted that, in consideration of the electrical connectivity of different assembled photovoltaic cell modules in the unified use process, each photovoltaic cell module of the present embodiment is further coupled with an electrical connection plug suitable for electrically connecting with other photovoltaic cell modules.

In an optional embodiment, the laminated thickness of the laminated plates 3 of every two adjacent photovoltaic cell modules after one-to-one lamination is smaller than the thickness of the photovoltaic unit 1. On the basis of the structure, after the connecting block 6 and the two laminated splicing plates 3 are laminated and matched, the end face of the connecting block 6, which is far away from the splicing plates 3, is flush with the front face of the photovoltaic unit 1; or when the connecting block 6 and the two laminated splicing plates 3 are laminated and matched, the end face of the connecting block 6 departing from the splicing plates 3 is slightly recessed relative to the front face of the photovoltaic unit 1, namely the end face of the connecting block 6 departing from the splicing plates 3 is slightly lower than the front face of the photovoltaic unit 1. The structure enables the front surfaces of the connecting blocks 2 and the connecting blocks 6 not to protrude from the front surface of the photovoltaic unit 1 from the front view angle of the assembled solar photovoltaic panel structure.

For the connection block 6 of the present embodiment, in an alternative implementation case, with reference to the attached drawings: the connecting block 6 comprises a body 61 in a square structure and a connecting column 62 which is convexly arranged at one end of the body 61 facing the splicing plate 3 and is suitable for being inserted into the inserting hole 5; the side length of the body 61 is equal to the side length of the splicing plate 3, and a good laminating matching effect is formed between the body 61 and the splicing plate 3 under the structure.

Namely, after the connecting column 62 penetrates through the splicing holes 5 of the two laminated splicing plates 3, the connecting column 62 is matched with the butterfly nut 63, so that the locking matching between the connecting column 62 and the splicing holes 5 can be realized. In another alternative embodiment, the connection post 62 may also be in interference fit with the insertion hole 5, that is, only the locking fit between the connection post 62 and the insertion hole 5 needs to be achieved to meet the use requirement of the present embodiment.

For example, for the above detailed situation that the end face of the joining block 6 away from the splice plate 3 is flush with the front face of the photovoltaic unit 1 after the joining block 6 and the two splice plates 3 after being laminated and mated, the following specific structure can be selected for implementation: for the four splice plates 3 included in each photovoltaic cell module, the thickness of each splice plate 3 is one third of the thickness of the photovoltaic unit 1, and the thickness of the body 61 of the junction block 6 is also one third of the thickness of the photovoltaic unit 1. Dividing the thickness of the whole photovoltaic unit 1 into three equal installation intervals, namely dividing the thickness of the photovoltaic unit 1 into a lower one-third installation interval, a middle one-third installation interval and an upper one-third installation interval; the bottom end surfaces of two splicing plates 3 positioned at two L-shaped end corners of one diagonal of the photovoltaic unit 1 are flush with the back surface of the photovoltaic unit 1, namely the splicing plates 3 at the moment are correspondingly arranged in a lower third installation interval of the L-shaped end corners from the back surface of the photovoltaic unit 1 to the front surface direction; and the two splicing plates 3 positioned at the two L-shaped end corners of the other diagonal line of the photovoltaic unit 1 are correspondingly installed in the middle third installation interval of the L-shaped end corners from the back side to the front side of the photovoltaic unit 1. Under such structure, every two adjacent photovoltaic cell modules are assembling the in-process, and splice plate 3 that is located the middle third installation interval superposes and presses on splice plate 3 that is located the lower third installation interval, so to two splice plates 3 after laminating, fold body 61 that links up piece 6 again and press on two splice plates 3, body 61 this moment then is the last third installation interval to the front direction that corresponds the back that is located photovoltaic unit 1. The overall thickness of the two splicing plates 3 and the body 61 of one joining block 6 after being laminated is exactly the same as that of the photovoltaic unit 1.

In conclusion, for the assembled solar photovoltaic structure of the embodiment, different photovoltaic cell modules can be connected by assembling and matching the splicing plates 3 and the connecting blocks 2 with each other only in a similar building block overlapping manner. So at the in-process that transports the pin-connected panel solar photovoltaic structure to this embodiment, only need with a certain amount of photovoltaic cell module encapsulate the transportation can, not only can reduce the packaging structure of transportation and be convenient for transport, can only change to the partial photovoltaic cell subassembly that breaks down when the solar photovoltaic structure breaks down and need maintain moreover, and need not change holistic solar photovoltaic structure, can greatly reduce use and cost of maintenance like this.
