Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaics, and more specifically to a photovoltaic component grounding connection structure and a photovoltaic component. Background Art

[0002] With the development of new energy industry, the photovoltaic industry is developing rapidly. Solar photovoltaic modules usually include solar cells, backplanes, aluminum frames and other components. Solar cells are usually not resistant to water vapor corrosion. When they encounter water vapor corrosion, the power generation performance of photovoltaic modules will be reduced. On the other hand, as the power of photovoltaic modules is getting higher and higher, when hot spots occur, the backplane packaging will cause the temperature of the photovoltaic module to rise due to poor heat dissipation performance, causing the backplane to melt, resulting in reduced stability of the photovoltaic module.

[0003] The backplane is usually made of aluminum. However, due to the high conductivity of aluminum, if leakage occurs, there is a high safety hazard. Since the backplane is packaged together with the solar cell, it is usually connected to the aluminum frame, and a grounding device is set on the aluminum frame to avoid safety hazards caused by leakage of the solar cell of the photovoltaic module.

[0004] The current grounding method used by photovoltaic modules is to mill a grounding hole on the C surface of the aluminum frame, wrap the two ends of the copper wire around two galvanized bolts, and then use galvanized bolts, nuts and washers to fix the copper wire to the grounding hole. Each photovoltaic module is connected with copper wire, and the copper wire connects the grounding hole at the other end of each photovoltaic module. This method is inconvenient to install during the actual installation process, consumes a lot of manpower, has a long working cycle, and affects the installation efficiency; at the same time, when using it, the copper wire is prone to loosening or falling off due to lack of compaction, or when the bolts and nuts and other connectors rust and fail, it will affect the grounding performance of the module.

[0029] Combination Figure 1 and Figure 2 As shown, this embodiment provides a photovoltaic module grounding connection structure, including a grounding component 3. The grounding component 3 can be connected to the photovoltaic module, and when the solar cell leaks electricity, it can be connected to the ground terminal through the grounding component 3, effectively reducing the occurrence of safety hazards.

[0030] The grounding assembly 3 includes a first clamping edge 31, a second clamping edge 33 and a first connecting edge 32, and the first clamping edge 31 and the second clamping edge 33 are connected through the first connecting edge 32. The first clamping edge 31 and the second clamping edge 33 are bent in a direction close to each other, so that the first clamping edge 31, the second clamping edge 33 and the first connecting edge 32 roughly form a U-shape, wherein the first clamping edge 31 and the second clamping edge 33 are located at the U-shaped edge.

[0031] In one case, the first clamping edge 31 and the second clamping edge 33 are clamped to an external device by approaching each other. In this embodiment, the first clamping edge 31 and the second clamping edge 33 are usually clamped on a side of the frame 1 of the photovoltaic module. In this case, the first clamping edge 31 and the second clamping edge 33 form an opening on the side away from the second clamping edge 33, and the distance between the first clamping edge 31 and the second clamping edge 33 at the opening is less than the thickness of the side of the clamped frame 1, so that the grounding component 3 can be firmly clamped on the frame 1. In this embodiment, the grounding component 3 is connected to the frame 1 by clamping, and the two can be quickly connected. The connection method is convenient and fast, and does not require bolt connection, nor does it require pre-setting connection holes on the frame 1. Moreover, the grounding component 3 can be flexibly clamped at a position of the frame 1 that is convenient for connection.

[0032] The grounding component 3 is also connected to the wire 2. In this embodiment, the second clamping edge 33 is connected to the wire 2. Of course, in other cases, the first clamping edge 31 can also be connected to the wire 2, or the first clamping edge 31 and the second clamping edge 33 can both be connected to the wire 2.

[0033] Recombination Figure 2As shown, in this embodiment, one side of the first clamping edge 31 is connected to the clamping caliper 35, and the clamping caliper 35 is located on the side where the first clamping edge 31 and the second clamping edge 33 are close. When clamping, the clamping caliper 35 and the second clamping edge 33 clamp each other. Specifically, the clamping caliper 35 is tilted, and the end of the clamping caliper 35 that is not connected to the first clamping edge 31 is the clamping end. The clamping caliper 35 is tilted in such a way that the clamping end faces the direction of the first connecting edge 32, so that the clamped component can enter between the clamping caliper 35 and the second clamping edge 33 for clamping. It should be noted that, in other cases, the clamping caliper 35 can also be set on one side of the second clamping edge 33, and the clamping caliper 35 is located on the side where the second clamping edge 33 and the first clamping edge 31 are close, and the clamping caliper 35 can be used to clamp each other with the first clamping edge 31.

[0034] Specifically in this embodiment, the clamping end of the clamping caliper 35 is further provided with a caliper protrusion 352, and the clamping end is further recessed to provide a caliper groove 351, and the caliper protrusion 352 is located at both ends of the caliper groove 351. During clamping, only the caliper protrusion 352 and the second clamping edge 33 are clamped, and the caliper protrusion 352 reduces the contact area between the clamping caliper 35 and the clamped component, thereby reducing the friction force, and the clamped component can be put between the caliper protrusion 352 and the second clamping edge 33 with relatively less effort.

[0035] The first clamping edge 31 is also provided with a clamping edge through hole 311, and the clamping clamp 35 is connected to the side of the clamping edge through hole 311 away from the first connecting edge 32. The clamping edge through hole 311 reduces the material of the grounding component 3 and facilitates the opening and closing between the first clamping edge 31 and the second clamping edge 33.

[0036] In order to quickly connect the second clamping edge 33 and the wire 2, a clamping sleeve 4 is arranged between the second clamping edge 33 and the wire 2. One end of the clamping sleeve 4 is pre-fixedly connected to the second clamping edge 33, and the other end is provided with a wire through hole. One end of the wire 2 is inserted into the wire through hole. After the wire through hole is pressed, the wire 2 can be quickly connected to the clamping sleeve 4.

[0037] Similarly, in order to facilitate the connection between the second clamping edge 33 and the wire 2, the end of the second clamping edge 33 away from the first connecting edge 32 is connected to the second connecting edge 34, and the second connecting edge 34 is bent in a direction away from the first clamping edge 31, and the second connecting edge 34 is connected to the ferrule 4. After the second connecting edge 34 is bent, a certain gap is reserved between the second connecting edge 34 and the clamped component, so as to facilitate the compression of the wire through hole and facilitate the connection between the second clamping edge 33 and the wire 2.

[0038] It should also be noted that the clamped component in this embodiment is a side edge of the frame 1, and the side edge is generally flat. Therefore, when clamping, the clamping caliper 35 presses the side edge against the second clamping edge 33, so that a surface contact is formed between the side edge and the second clamping edge 33, which can increase the conduction power, make the grounding component 3 less likely to be burned by a large current, and improve the service life of the grounding component 3.

[0039] Combination Figure 1 and Figure 3 As shown, in another embodiment, a photovoltaic assembly is provided, including a photovoltaic assembly monomer, the photovoltaic assembly monomer including a photovoltaic panel 5 and a frame 1 located around the photovoltaic panel 5. A photovoltaic assembly grounding connection structure in the above embodiment is also included, wherein the grounding assembly 3 is connected to the frame 1. Figure 1 In the figure, the photovoltaic panel 5 is located on the A surface of the frame 1, and the side of the frame 1 away from the A surface is the C surface; Figure 3 In the figure, the outer side of the frame 1 after enclosing the photovoltaic panel 5, that is, the side away from the center of the photovoltaic panel 5, is the B side of the frame 1. The C side frame 11 is set on the side of the frame 1 close to the C side, and the C side frame 11 protrudes in the direction away from the B side. The first clamping edge 31 and the second clamping edge 33 are clamped on the C side frame 11. In this case, the grounding component 3 is clamped and connected to the C side frame 11, one end of the wire 2 is connected to the ferrule 4, and the other end is grounded.

[0040] Recombination Figure 3 As shown, in other cases, the photovoltaic module includes more than two photovoltaic module monomers, and the sides of the frames 1 of adjacent photovoltaic module monomers that are close to each other are connected to the grounding components 3, and the two grounding components 3 are connected to each other through the wire 2, that is, one end of the wire 2 is connected to a grounding component 3, and the other end is connected to another grounding component 3, so that the adjacent photovoltaic module monomers are connected through the two grounding components 3 and the wire 2. In this case, a grounding component 3 is further connected to the frame 1 of one of the photovoltaic module monomers, and the grounding component 3 is connected to the wire 2, and the other end of the wire 2 is grounded. In this case, the photovoltaic module monomers are connected through the grounding component 3, and are grounded through a grounded wire 2, forming a grounding path for the photovoltaic module, which is simple and safe in structure.

[0041] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
