Description

Technical Field

[0001] The present invention relates to the technical field of circuit wiring equipment, in particular to a photovoltaic component wiring device for photovoltaic power generation. Background Art

[0002] In the photovoltaic power generation sector, photovoltaic module wiring devices are used to reliably connect and protect photovoltaic circuits. Their core is to ensure the stability, sealing, and environmental adaptability of the circuit connections through mechanical structural design. Through the synergistic effect of connecting tubes, fixing mechanisms, and sealing mechanisms, the device can adaptively secure circuits of varying diameters. Its elastic buffering and sealing design prevents failures at the circuit connections caused by external bending or water seepage. Suitable for photovoltaic system installations in complex outdoor environments, it plays a significant role in improving the reliability and service life of photovoltaic module electrical connections.

[0003] Traditional photovoltaic module wiring devices have significant shortcomings. In terms of fixing methods, traditional equipment often relies on rigid fixing methods such as screws or clips. This is not only cumbersome, time-consuming and labor-intensive, but the screws are prone to rust and corrosion, resulting in fixation failure or poor contact, increasing equipment maintenance costs. In terms of compatibility, traditional devices are difficult to adapt to lines of different diameters and require various types of clamps, which limits their application scenarios. In terms of sealing performance, traditional structures often use simple glue seals or split housings, which are prone to gaps due to ambient temperature differences or external forces, allowing rainwater to seep and cause short circuit risks. Heat dissipation capacity is insufficient, and the lack of effective heat dissipation design can easily lead to heat accumulation at line connections, affecting conductivity and even posing safety hazards. In addition, traditional devices have poor ability to buffer line bends, and external forces can easily cause line breakage or loose connections. They cannot meet the stability requirements of photovoltaic modules in complex installation environments, and urgently need to improve automated fixing, sealing, and heat dissipation performance through innovative designs.

When the line connection is completed, the rotating ring on the connecting tube is rotated clockwise again to cause the No. 1 plug-in board and the No. 2 plug-in board to begin to expand, and pull the connection of the line to the inside of the connecting tube. After the movement is completed, the rotating ring is released, and the No. 1 plug-in board and the No. 2 plug-in board begin to reset and be pressed and fitted against the outer surface of the line, thereby automatically completing the fixation of the device and the line after the line connection is completed, greatly reducing the cumbersomeness of the operation of the device, and at the same time eliminating the traditional screw fixing method, greatly reducing the problem of equipment failure caused by rusted screws.

[0020] (3) The photovoltaic module wiring device for photovoltaic power generation has an elastic bag fixedly connected to the outer surface of the No. 1 plug-in board, and the No. 1 plug-in board is movably fitted on the inner surface of the mounting ring, so that the No. 1 plug-in board and the No. 2 plug-in board can be moved in multiple directions within the mounting ring, so that when the circuits at both ends of the connecting tube are bent, the center axis of the whole formed by the No. 1 plug-in board and the No. 2 plug-in board can be dislocated relative to the center axis of the mounting ring, and the No. 1 plug-in board and the No. 2 plug-in board are always fitted on the outer surface of the circuit, thereby providing a buffer distance at one end for the bending part of the circuit when the circuit is bent, greatly improving the protection of the circuit while not losing the fixing effect on the circuit, and when the inner When the ring rotates, it will drive the connecting ring on the isolation ring to rotate through the adapter rod, thereby driving the toggle plate on the inner surface of the connecting ring to start rotating clockwise, that is, gradually losing the squeezing effect on the moving plate.

When the line connection moves between the two isolation rings, the rotating ring is released. At this time, the toggle plate begins to reset counterclockwise, that is, it begins to squeeze the moving plate to shrink, and finally squeezes the sealing bag onto the outer surface of the line, that is, it achieves the simultaneous completion of fixing the line and squeezing and sealing of both sides of the line connection, further reducing the problem of water seepage at the line connection causing circuit short circuit.

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] First embodiment: Figures 1 to 8 As shown, the present invention provides a technical solution: a photovoltaic module wiring device for photovoltaic power generation, comprising a connecting pipe 1, with mounting rings 2 symmetrically fixedly connected to the inner surfaces of both ends of the connecting pipe 1, and further comprising:

[0032] The fixing mechanism 3 is fixedly mounted on the connecting pipe 1;

[0033] The sealing mechanism 4 is fixedly mounted on the inner surface of the connecting pipe 1;

[0034] The fixing mechanism 3 includes a rotating ring 31, which is symmetrically connected to the outer surfaces of both ends of the connecting tube 1. The two rotating rings 31 are fixedly connected by a connecting rod. A sliding groove 32 is provided on the outer surfaces of both ends of the connecting tube 1. The rotating ring 31 is arranged just outside the sliding groove 32. The inner surfaces of both ends of the connecting tube 1 are rotatably connected to the inner ring 33. The outer surface of the inner ring 33 is fixedly connected to the connecting block 34. The connecting block 34 is slidably arranged in the sliding groove 32. The inner ring 33 and the rotating ring 31 are fixedly connected by the connecting block 34.

[0035] A ventilation groove 35 is provided in the middle wall of the connecting pipe 1 , and a ventilation hole 36 is provided through the middle outer surface of the connecting pipe 1 , and the ventilation hole 36 is communicated with the ventilation groove 35 .

[0036] The interior of the mounting ring 2 is set to be hollow, and the inner surface of the mounting ring 2 is slidingly fitted with a No. 1 plug-in board 37, and the two ends of the No. 1 plug-in board 37 are elastically slidably plugged with the No. 2 plug-in board 38. The outer surface of the No. 2 plug-in board 38 is provided with a limiting groove 39, wherein the No. 1 plug-in board 37 and the No. 2 plug-in board 38 are limited by the limiting groove 39, and the No. 1 plug-in board 37 and the No. 2 plug-in board 38 are combined into a ring shape.

[0037] The bottom inner surface of the No. 1 plug-in board 37 is fixedly connected with a connecting rope 310, the inner surface of the mounting ring 2 is fixedly connected with a No. 1 limiting ring 311, four No. 1 limiting rings 311 are arranged at fixed intervals along the central axis of the mounting ring 2, the inner elastic sliding connection of the No. 1 limiting ring 311 is connected with a sliding rod 312, the inner surface of the mounting ring 2 is fixedly connected with a limiting buckle 313, and the connecting rope 310 is fixedly connected to the sliding rod 312 through the limiting buckle 313.

[0038] A second limiting ring 314 is fixedly connected to the surface of the inner ring 33 on one side close to the mounting ring 2. The second limiting ring 314 is arranged in the same shape as the first limiting ring 311, and the end of the sliding rod 312 away from the first limiting ring 311 is elastically slidably connected in the second limiting ring 314.

[0039] The outer end of the No. 1 plug-in board 37 is fixedly connected to an elastic bag 315, which is fixedly embedded in the inside of the mounting ring 2. The elastic bag 315 is set to be annular. The side surface of the connecting block 34 is fixedly connected to an elastic sheet 316, which is set to be corrugated. The elastic sheet 316 is set in the slide groove 32.

[0040] Second embodiment: Figures 1 to 8As shown, the sealing mechanism 4 includes an isolation ring 41, which is symmetrically fixedly connected to the inner surfaces of both sides of the connecting pipe 1. The isolation ring 41 is arranged on the inner side of the mounting ring 2. A connecting ring 42 is rotatably embedded in the isolation ring 41. A connecting groove 43 is opened through the isolation ring 41, and four connecting grooves 43 are arranged at fixed intervals along the center axis of the isolation ring 41.

[0041] A transfer rod 44 is fixedly connected to the side surface of the connecting ring 42 . The transfer rod 44 is disposed in the connecting groove 43 . One end of the transfer rod 44 away from the connecting ring 42 is fixedly connected to the surface of the inner ring 33 away from the mounting ring 2 .

[0042] The inner surface of the isolation ring 41 is fixedly connected with a collar 45, the interior of the collar 45 is set to be hollow, the inner surface of the collar 45 is elastically and slidingly connected with a movable plate 46, four movable plates 46 are set at fixed intervals around the central axis of the collar 45, and a toggle plate 47 is extruded at the outer end of the movable plate 46. The inner surface of the toggle plate 47 is set to an inclined surface, and the end of the toggle plate 47 away from the movable plate 46 is fixedly connected to the inner surface of the connecting ring 42, and a sealing bag 48 is fixedly connected between the four movable plates 46.

[0043] When working, the line to be connected is completely passed through the connecting tube 1, and the line connection is made outside the connecting tube 1. Then, the connection of the connected line is pulled into the connecting tube 1 to complete the overall installation. Before passing the line through the connecting tube 1, the rotating ring 31 on the connecting tube 1 can be rotated clockwise. When the connecting tube 1 rotates, the inner ring 33 is driven to rotate through the connecting block 34, which causes the elastic sheet 316 in the slide groove 32 to be squeezed. When the inner ring 33 starts to rotate, it drives the second limiting ring 314 to start rotating relative to the slide bar 312. When the elastic force between the second limiting ring 314 and the slide bar 312 reaches the maximum, it drives the slide bar 312 to start sliding along the first limiting ring 311, and finally through the matching of the limiting buckle 313 and the connecting rope 310. The first plug-in plate 37 is pulled together, thereby causing the first plug-in plate 37 and the second plug-in plate 38 to expand, thereby causing the through-hole on the mounting ring 2 to begin to enlarge. When the line has completely passed through the connecting tube 1, the rotation of the rotating ring 31 can be released and the line connection can be made. At this time, under the action of the elastic force, the first plug-in plate 37 and the second plug-in plate 38 begin to shrink and reset, thereby causing the inner surfaces of the first plug-in plate 37 and the second plug-in plate 38 to be squeezed and fitted to the outer surface of the line. When the line connection is completed, the rotating ring 31 on the connecting tube 1 is rotated clockwise again to cause the first plug-in plate 37 and the second plug-in plate 38 to begin to expand, and the connection of the line is pulled to the inside of the connecting tube 1. After the movement is completed, the rotating ring 31 is released, and the first plug-in plate 37 and the second plug-in plate 38 are reconnected. It starts to reset and squeeze and fit on the outer surface of the line, thereby automatically completing the fixation of the device and the line after the line connection is completed, greatly reducing the cumbersomeness of the operation of the device, and at the same time eliminating the traditional screw fixing method, greatly reducing the problem of equipment failure caused by rusted screws, and the variable No. 1 plug-in board 37 and No. 2 plug-in board 38 can also make the device match lines of different diameters, greatly improving the applicability of the device, and at the same time, the one-piece forming connecting pipe 1 is also different from the traditional rotating buckle type shell, which greatly reduces the problem of water ingress into the equipment and avoids short circuit behavior at the line connection. The ventilation slots 35 and ventilation holes 36 opened can also greatly reduce the wall thickness of the connecting pipe 1 at the line connection, thereby greatly reducing the connection pipe 1. The internal temperature is maintained, thereby avoiding the problem of excessive temperature at the line connection during operation, greatly improving the stability of the line operation. Because the outer surface of the No. 1 plug-in board 37 is fixedly connected to the elastic bag 315, and the No. 1 plug-in board 37 is movably fitted to the inner surface of the mounting ring 2, the No. 1 plug-in board 37 and the No. 2 plug-in board 38 are combined as a whole and can move in multiple directions within the mounting ring 2. Therefore, when the lines at both ends of the connecting pipe 1 are bent, the center axis of the whole formed by the No. 1 plug-in board 37 and the No. 2 plug-in board 38 can be dislocated relative to the center axis of the mounting ring 2, and the No. 1 plug-in board 37 and the No. 2 plug-in board 38 are always fitted to the outer surface of the line, thereby providing a buffer distance at one end for the bending point of the line when the line is bent.The protective effect on the circuit is greatly improved while maintaining the fixing effect on the circuit. When the inner ring 33 rotates, it will drive the connecting ring 42 on the isolation ring 41 to rotate through the adapter rod 44, thereby driving the toggle plate 47 on the inner surface of the connecting ring 42 to begin to rotate clockwise, that is, gradually losing the squeezing effect on the movable plate 46. At this time, the movable plate 46 begins to move into the ring 45 under the action of elastic force, that is, driving the sealing capsule 48 to begin to expand, ensuring that the connection of the circuit can pass through the ring 45 normally. When the circuit connection moves between the two isolation rings 41, the rotating ring 31 is released. At this time, the toggle plate 47 begins to reset counterclockwise, that is, it begins to squeeze the movable plate 46 to shrink, and finally squeezes the sealing capsule 48 against the outer surface of the circuit, that is, it achieves the simultaneous completion of the fixing of the circuit and the simultaneous squeezing and sealing of both sides of the circuit connection, further reducing the problem of water seepage at the circuit connection causing circuit short circuit.
