Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic power generation technology, and specifically relates to a photovoltaic module wiring assembly for photovoltaic power generation. Background Technology

[0002] Ensuring the stability and safety of photovoltaic (PV) modules is crucial in their application. With the continuous development of PV technology, the installation and maintenance methods of PV modules are receiving increasing attention. Traditional PV module wiring devices often employ direct welding or simple mechanical fixing methods. While these methods can achieve basic electrical connections, they are prone to problems such as cable wear and loose connections during long-term use. This not only affects the power generation efficiency of the PV system but may also pose safety hazards. Especially in complex outdoor environments, factors such as wind, sand, rain erosion, and temperature changes accelerate cable bending and aging, increasing maintenance costs and difficulty.

[0003] In existing technologies, some photovoltaic module wiring assemblies leave the connectors suspended after wiring, making the wires prone to loosening and breakage. At the same time, the connectors are easily oxidized due to long-term contact with the outside air. Therefore, in order to reduce the problem of poor contact caused by loosening and oxidation of the connectors, a photovoltaic module wiring assembly for photovoltaic power generation is needed. Utility Model Content

[0004] The purpose of this utility model is to provide a photovoltaic module wiring assembly for photovoltaic power generation that is simple in structure and reasonably designed in order to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A photovoltaic module wiring assembly for photovoltaic power generation includes a photovoltaic panel, a bracket fixedly mounted on the bottom of the photovoltaic panel, a fixing component mounted on the top of the bracket, and a connection protection component mounted on the bottom of the fixing component. The fixing component includes a U-shaped connecting block fixedly connected to the top of the bracket, and a screw threaded through the side wall of the bracket is threaded onto the inner wall of the U-shaped connecting block.

[0007] As a further optimization of this utility model, the connection protection component includes an upper cover fixedly connected to the bottom of the U-shaped connecting block, a mounting base rotatably connected to the outer wall of the upper cover, a buckle fixedly connected to the outer side of the upper cover, and a lock body that engages with the buckle fixedly connected to the outer wall of the mounting base.

[0008] As a further optimization of this utility model, the inner walls on both sides of the mounting base are provided with insertion holes, and two sets of fixing blocks are fixedly connected to the top of the mounting base. A connecting rod is fixedly connected between each set of fixing blocks. Two torsion springs are fixedly connected to the top of the mounting base on one side of the outer wall of the connecting rod, and an arc-shaped pressure plate is fixedly connected to the outer wall of the connecting rod on the other side of the torsion spring.

[0009] As a further optimization of this utility model, the outer side of the arc-shaped pressure plate is fixedly connected with two plugs inserted into the mounting base, and the bottom of the upper cover is fixedly connected with a pressure rod that abuts against the top of the arc-shaped pressure plate.

[0010] As a further optimization of this utility model, a male connector is fixedly connected to the top of the mounting base, and one end of the male connector is inserted into a female connector fixedly connected to the top of the mounting base.

[0011] As a further optimization of this utility model, a sealing ring is fixedly connected to the bottom of the top cover, and a fixing groove that mates with the sealing ring is provided on the top of the mounting base.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. This utility model involves first threading the wires of the left photovoltaic panel through the socket, then lifting the arc-shaped pressure plate to retract the torsion spring, separating the plug from the mounting base, connecting the wires to the male connector, releasing the arc-shaped pressure plate to reset the torsion spring and the plug, and repeating the operation to connect the right photovoltaic panel wires to the female connector, thus connecting the positive and negative terminals of the photovoltaic panel. Finally, rotating the top cover allows the pressure rod to press down on the arc-shaped pressure plate, engaging the lock body and the latch to complete the positive and negative connection. This shortens installation time, reduces the number of exposed cables and connectors, reduces poor contact problems caused by loose connectors and oxidation, and better resists the intrusion of rainwater and dust.

[0014] 2. This utility model allows the U-shaped connecting block to slide along the outer wall of the bracket, so that the magnetic sticker on its back adheres to the bracket. Then, by tightening the screw, the top cover can be fixed on the bracket. This can prevent loosening due to external forces such as wind and vibration, prevent the mounting base from falling off, which could lead to cable pulling and breakage, reduce the risk of circuit interruption, effectively prevent friction between the top cover and the bracket edge, delay the aging of the insulation layer, and reduce the risk of leakage and short circuit.

[0021] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0022] Example: Figure 1 , Figure 2 , Figure 5 As shown, a photovoltaic module wiring assembly for photovoltaic power generation includes a photovoltaic panel 2, which can receive solar energy and convert it into electrical energy. A bracket 1 is fixedly installed at the bottom of the photovoltaic panel 2, serving as the basic support component of the entire device. A fixing component 3 is installed at the top of the bracket 1, which is used to stably fix subsequent components on the bracket 1. The fixing component 3 includes a U-shaped connecting block 301, which can be fitted against the outer wall of the bracket 1 for initial positioning. A magnetic adhesive patch is provided on one side of the U-shaped connecting block 301 for pre-fixing. The external of the U-shaped connecting block 301 is fixedly connected to the top of the bracket 1, so that the U-shaped connecting block 301 and the bracket 1 form a stable connection. A screw 302 is threadedly connected to the inner wall of the U-shaped connecting block 301. Tightening the screw 302 can further strengthen the connection between the U-shaped connecting block 301 and the bracket 1 and prevent the U-shaped connecting block 301 from loosening. The outer wall of the screw 302 penetrates the side wall of the bracket 1, enhancing the connection stability between the U-shaped connecting block 301 and the bracket 1.

[0023] like Figure 2 , Figure 3As shown, a connection protection component 4 is provided at the bottom of the fixing component 3. The connection protection component 4 can protect the connection parts of the photovoltaic panel 2 wires to prevent external dust and moisture from affecting the connection effect. The connection protection component 4 includes an upper cover 401, which serves as a shield and protector. The top of the upper cover 401 is fixedly connected to the bottom of the U-shaped connecting block 301. The upper cover 401 is stably installed on the bracket 1 through the U-shaped connecting block 301. The outer wall of the upper cover 401 is rotatably connected to the mounting base 402. The mounting base 402 is used to provide the installation foundation and facilitates the opening and closing of the upper cover 401 for easy wire connection. A latch 410 is fixedly connected to the outer side of the upper cover 401. A lock body 411 is fixedly connected to the outer wall of the mounting base 402. After the lock body 411 and the latch 410 are engaged, the upper cover 401 cannot be opened at will, ensuring the safety of the internal components. The outer wall of the lock body 411 engages with the outer wall of the latch 410 to enhance the protection effect.

[0024] like Figure 2 , Figure 3 , Figure 4 As shown, the inner walls on both sides of the mounting base 402 are provided with insertion holes 403, which provide a passage for the wires of the photovoltaic panel 2. Two sets of fixing blocks 404 are fixedly connected to the top of the mounting base 402. The fixing blocks 404 are used to provide a fixing base. A connecting rod 405 is fixedly connected between each set of fixing blocks 404. The connecting rod 405 is used to provide an installation base. Two torsion springs 406 are sleeved on the outer wall of the connecting rod 405. The torsion springs 406 are used to provide a certain downward pressure. One side of the two torsion springs 406 is fixedly connected to the top of the mounting base 402 to ensure stable elastic action. An arc-shaped pressure plate 407 is fixedly connected to the other side of the two torsion springs 406. The torsion springs 406 can realize the reset of the arc-shaped pressure plate 407 through their own elasticity. The outer wall of the arc-shaped pressure plate 407 is rotatably connected to the outer wall of the connecting rod 405 to improve the stability of the rotation of the arc-shaped pressure plate 407.

[0025] like Figure 2 , Figure 3As shown, two plugs 408 are fixedly connected to the outer side of the arc-shaped pressure plate 407. When the plugs 408 are inserted into the mounting base 402, they can fix the position of the arc-shaped pressure plate 407, ensuring a stable connection between the wire and the connector. The outer sides of the two plugs 408 are inserted into the interior of the mounting base 402, restricting the movement of the arc-shaped pressure plate 407 and preventing the wire connection from becoming loose. A pressure rod 413 is fixedly connected to the bottom of the top cover 401. When the top cover 401 is rotated, the pressure rod 413 can press down on the arc-shaped pressure plate 407, further reinforcing the connection between the plugs 408 and the mounting base 402. One end of the pressure rod 413 abuts against the top of the arc-shaped pressure plate 407, enhancing the fixing effect. A male connector 414 is fixedly connected to the top of the mounting base 402. One end of the male connector 414 is inserted into a female connector 415. The head connector 414 can cooperate with the female connector 415 to connect the positive and negative terminals of the photovoltaic panel 2 wires, forming a circuit between the positive and negative terminals of the photovoltaic panel 2 to ensure normal power transmission. The outer wall of the female connector 415 is fixedly connected to the top of the mounting base 402 to prevent misalignment during docking. A sealing ring 412 is fixedly connected to the bottom of the top cover 401. The sealing ring 412 can fill the gap between the top cover 401 and the mounting base 402, enhancing the sealing performance of the device and preventing dust and moisture from entering. A fixing groove 409 is provided on the top of the mounting base 402. The fixing groove 409 provides an installation position for the sealing ring 412, ensuring that the sealing ring 412 and the mounting base 402 fit tightly. The inner wall of the fixing groove 409 cooperates with the sealing ring 412 to ensure that the internal components are not affected by the external environment.

[0026] It should be noted that, in use, the wiring assembly for photovoltaic modules used in photovoltaic power generation involves first passing the wires on the left photovoltaic panel 2 through the socket 403, then lifting the arc-shaped pressure plate 407 to retract the torsion spring 406, then separating the plug 408 from the mounting base 402, allowing the wires to be inserted into the male connector 414. Then, releasing the arc-shaped pressure plate 407 allows the torsion spring 406 to return to its original position, and the plug 408 to re-engage with the mounting base 402. This process is repeated. Then, the wires on the right photovoltaic panel 2 are inserted into the female connector 415, connecting the positive and negative terminals of the photovoltaic panel 2. Finally, rotating the top cover 401 causes the pressure rod 413 to press down on the arc-shaped pressure plate 407, and then engaging the lock body 411 with the latch 410, thus completing the connection of the positive and negative terminals of the photovoltaic panel 2.

[0027] When fixing the top cover 401 to the bracket 1, first slide the U-shaped connecting block 301 along the outer wall of the bracket 1, and then the magnetic sticker on the back of the U-shaped connecting block 301 attaches to the bracket 1, so that the screw 302 can be turned to fix the top cover 401 to the bracket 1.

[0028] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
