Description

Technical Field

[0001] This utility model relates to the field of solar photovoltaic cells, and specifically to a solar photovoltaic cell module connection device. Background Technology

[0002] Traditional photovoltaic (PV) cells are typically bonded together with aluminum alloy frames using special adhesives or silicone. While this method provides strong adhesion, it suffers from several major problems in practical applications: First, the bonding process is complex and time-consuming. Precise application of the adhesive or silicone during production and waiting for complete curing not only increases production time and costs but can also lead to low production efficiency. Second, the bonding method hinders disassembly and replacement. If a PV cell malfunctions or requires an upgrade, special tools must be used to remove the adhesive or silicone, which is not only time-consuming and labor-intensive but may also damage the cell and frame. Furthermore, the presence of adhesive makes disassembly and transportation of the modules extremely difficult, increasing logistics costs and risks. Finally, it exhibits poor environmental adaptability; conductive adhesive bonding performs unstably and is prone to failure in harsh environments such as high temperature and high humidity.

[0031] Example 1

[0032] like Figures 1-3 As shown, this embodiment describes in detail 1. A solar photovoltaic cell module connection device, characterized in that it includes: a cell 1, a cell outer frame 2, a power module, insulated wires, an electromagnet 3, a ferromagnetic component 4, a U-shaped fixing frame 5, and a control unit; the electromagnet 3 is installed on one side of each cell outer frame 2 and connected to the power module; as shown Figure 2 As shown, the ferromagnetic component 4 is installed on one side of the adjacent battery outer frame 2 for cooperating with the electromagnet 3; preferably, the surface of the ferromagnetic component 4 is plated with nickel or zinc, and the surface of the ferromagnetic component 4 is also sprayed with an anti-corrosion coating to prevent rust; the power module is a circuit formed by the battery cell 1 and the external circuit, used to provide a stable DC power supply to the electromagnet 3; the control unit is connected between the power module and the electromagnet 3 for controlling the opening and closing of the electromagnet 3; the insulated wire is used to connect the power module, the electromagnet 3 and the control unit; the U-shaped fixing bracket 5 is used to fix the electromagnet 3.

[0033] Specifically, the wiring method is as follows: connect the positive terminal of the power module to the positive input terminal of the control unit; connect the negative terminal of the power module to the negative input terminal of the control unit; connect the first output terminal of the control unit to the positive terminal of an electromagnet 3; connect the negative terminal of the electromagnet 3 to the common negative terminal of the control unit; repeat the above steps to connect the other output terminals of the control unit to the positive terminals of other electromagnets 3 respectively; connect the negative terminals of all electromagnets 3 to the common negative terminal of the control unit.

[0034] like Figure 3 As shown, the U-shaped fixing bracket 5 has several screw holes on the side that contacts the battery outer frame 2, and is fixed in the groove 21 on the outside of the battery outer frame 2 by screws; the thickness of the ferromagnetic component 4 and the thickness of the U-shaped fixing bracket 5 are exactly the thickness of the groove 21, so that the two can be tightly connected; the two open ends of the U-shaped fixing bracket 5 face the ground and have screw holes; the two open ends of the U-shaped fixing bracket 5 facing the ground have flexible sheets 51; the side of the U-shaped fixing bracket 5 that contacts the electromagnet 3 also has an elastic guide groove.

It should be noted that the U-shaped fixing bracket 5 is placed in the groove 21 for rain protection. The open ends of the U-shaped fixing bracket 5 face the ground to prevent water accumulation. The flexible sheet 51 is used to fix the electromagnet 3 to facilitate further clamping of the electromagnet 3 so that it is not easy to shake. Similarly, the ferromagnetic component 4 is fixed to the outside of the adjacent battery outer frame 2 by threaded connection. When the battery cells 1 are connected to each other through the battery outer frame 2, the control unit controls the battery module to be powered on. At this time, the ferromagnetic component 4 and the electromagnet 3 installed on the two battery outer frames 2 respectively attract each other. When it is necessary to separate the battery cells 1, the control unit controls the battery module to be powered off. At this time, the ferromagnetic component 4 and the electromagnet 3 installed on the two battery outer frames 2 respectively separate from each other.
