[0002] The grid-connected photovoltaic power generation system can convert the direct current output by the solar cell array into alternating current with the same amplitude, frequency and phase as the grid voltage, and connect to the grid and transmit electric energy to the grid. The flexibility of this power generation system lies in that when the sunshine is strong, the photovoltaic power generation system can supply the AC load with power and send the excess electric energy to the grid; when the sunshine is insufficient, that is, the solar cell array cannot provide enough electric energy for the load, it can obtain electric energy from the grid to power the load.

However, the existing grid-connected switch detection device cannot detect grid-connected switches of different models. Therefore, when testing grid-connected switches of different models, it is necessary to replace the detection device of the same model, which is time-consuming, labor-intensive, and inefficient.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0030] See also Figure 1-Figure 6 As shown, the utility model is a detection device for a photovoltaic grid-connected switch, comprising a detection platform 1, a mounting block 2 is fixedly connected to the top of the detection platform 1, a synchronization component 3 is arranged inside the mounting block 2, a clamping component 4 is fixedly connected to one end of the synchronization component 3, a reset component 5 is arranged inside the mounting block 2, one side of the reset component 5 is fixedly connected to one side of the synchronization component 3, a support component 6 is fixedly installed on the top of the detection platform 1, and a connecting component 7 is slidably arranged inside the support component 6.

[0031] When in use, the synchronous component 3 fixedly connected on one side is driven to move by pulling the clamping component 4, so that the distance between the clamping components 4 can be adjusted. Since one side of the synchronous component 3 is fixedly connected to one side of the reset component 5, when the synchronous component 3 moves, it can drive the reset component 5 fixedly connected on one side to move. Then the grid-connected switch to be detected is placed on the top of the mounting block 2, and then the clamping component 4 is released, so that the reset component 5 performs a reset movement. When the reset component 5 moves, it can drive the synchronous component 3 fixedly connected on one side to move. When the synchronous component 3 moves, it can drive the clamping component 4 fixedly connected at one end to move, so that it fixes the position of the grid-connected switch. Then the connecting component 7 is pulled to move, and at the same time, the connecting component 7 is pushed to move in cooperation with the supporting component 6 slidingly arranged on its outer surface, so that one end of the connecting component moves to the wiring terminal of the grid-connected switch, and the connecting component 7 is released, and it is pushed into the wiring terminal of the grid-connected switch under the action of its own elastic force to make an electrical connection, so as to facilitate its detection.

[0032] The utility model drives the synchronous component 3 to move by pulling the clamping component 4, so that the distance between the clamping components 4 can be adjusted. At the same time, the synchronous component 3 drives the reset component 5 to move, and then the grid-connected switch to be detected is placed on the top of the mounting block 2, and the clamping component 4 is released to make the reset component 5 perform a reset movement, and the reset component 5 drives the synchronous component 3 to move, and the synchronous component 3 drives the clamping component 4 to move, so that the position of the grid-connected switch is fixed. Since the distance between the clamping components 4 can be adjusted in conjunction with the synchronous component 3, it is convenient to detect grid-connected switches of different models and sizes, and there is no need to replace the detection equipment according to the model of the grid-connected switch, which is time-saving and labor-saving, and has high efficiency.

[0033] In one embodiment, for the above-mentioned synchronization component 3, the synchronization component 3 includes a rotating shaft 301, both ends of the rotating shaft 301 are arranged to rotate inside the mounting block 2, the outer surface of the rotating shaft 301 is fixedly connected with a gear 302, the surface of the gear 302 is meshingly connected with two groups of racks 303, and one end of the two groups of racks 303 is fixedly connected to one side of the clamping component 4.

[0034] By pulling the clamping assembly 4, one of the groups of racks 303 fixedly connected to one side thereof is driven to move. When one of the groups of racks 303 moves, it can drive the gear 302 meshingly connected to its surface to rotate. When the gear 302 rotates, it can drive another group of racks 303 meshingly connected to its surface to move. Since one end of the other group of racks 303 is also fixedly connected to one side of the clamping assembly 4, when the other group of racks 303 moves, the clamping assembly 4 can be moved synchronously relative to each other, thereby facilitating the adjustment of the distance between the clamping assemblies 4.

[0035] In one embodiment, for the above-mentioned clamping assembly 4, the clamping assembly 4 includes two groups of fixing frames 401, one side of the two groups of fixing frames 401 is respectively fixedly connected to one end of the two groups of racks 303, a pull rod 402 is fixedly connected to the inner side of the fixing frame 401, and a clamp plate 403 is fixedly installed on one side of the fixing frame 401.

[0036] By pulling the pull rod 402, the fixed frame 401 fixedly connected at both ends is driven to move. Since one side of the two groups of fixed frames 401 is respectively fixedly connected to one end of the two groups of racks 303, when the fixed frame 401 moves, it can drive the rack 303 fixedly connected on one side to move, and cooperate with the gear 302 to make it move relatively synchronously. When the fixed frame 401 moves, it can drive the clamping plate 403 to move relatively, so that it is convenient for it to clamp and fix the grid-connected switch.

[0037] In one embodiment, for the above-mentioned reset component 5, the reset component 5 includes a sliding rod 501, both ends of the sliding rod 501 are fixedly connected to the inside of the mounting block 2, a sliding block 502 is slidably provided on the outer surface of the sliding rod 501, one side of the sliding block 502 is fixedly connected to a reset spring 503, one end of the reset spring 503 is fixedly connected to the inside of the mounting block 2, and one side of the sliding block 502 is fixedly connected to one side of the rack 303.

[0038] When the rack 303 moves with the rotation of the gear 302, it can drive the sliding block 502 fixedly connected to one side thereof to move. When the sliding block 502 moves, it can drive the return spring 503 fixedly connected to one side thereof to be squeezed. Since the interior of the sliding block 502 is slidingly arranged with the outer surface of the sliding rod 501, when the sliding block 502 moves, it can move along the direction of the sliding rod 501, thereby avoiding deviation during the movement process and improving the stability of the sliding block 502 during the movement process.

[0039] In one embodiment, for the above-mentioned support component 6, the support component 6 includes a support frame 601, the bottom end of the support frame 601 is fixedly installed on the top end of the detection table 1, and a moving block 602 is slidably arranged inside the support frame 601, and the inside of the moving block 602 is slidably arranged on the outer surface of the connecting component 7.

[0040] When the connecting component 7 is moved, the moving block 602 slidingly arranged on its outer surface can be driven to slide inside the supporting frame 601. There are multiple groups of moving blocks 602, corresponding to the number of the connecting components 7, so as to facilitate the adjustment of the position of the connecting component 7 so that it can adapt to different types of grid-connected switches, thereby improving the application range of the detection device of the photovoltaic grid-connected switch.

[0041] In one embodiment, for the above-mentioned connection component 7, the connection component 7 includes an insulating sleeve 701, the outer surface of the insulating sleeve 701 is slidably arranged inside the moving block 602, the outer surface of the insulating sleeve 701 is fixedly connected to a limiting plate 702, one side of the limiting plate 702 is fixedly connected to a spring 703, and one end of the spring 703 is fixedly connected to one side of the moving block 602;

[0043] By pulling the insulating sleeve 701, the limiting plate 702 fixedly connected on its surface can be driven to move. When the limiting plate 702 moves, the spring 703 fixedly connected on one side thereof can be compressed, thereby preventing the insulating sleeve 701 from escaping from the interior of the moving block 602. Then, the insulating sleeve 701 is moved laterally, so that it can cooperate with the moving block 602 to move inside the support frame 601, and then its position is adjusted. When the insulating sleeve 701 moves, it can drive the connecting piece 704 fixedly connected inside it to move and make it correspond to the wiring terminal of the grid-connected switch. Then, the insulating sleeve 701 is released. Under the action of the spring 703, it can cooperate with the limiting plate 702 to drive the insulating sleeve 701 to move. The insulating sleeve 701 drives the connecting piece 704 to move, so that it enters the wiring terminal of the grid-connected switch to complete the connection. By connecting the wiring harness connector 705 to the external test wiring harness, the detection of the grid-connected switch can be completed.

[0044] In one embodiment, for the above-mentioned support frame 601, a limiting groove 8 is opened inside the support frame 601, a limiting block 9 is slidably arranged inside the limiting groove 8, and one side of the limiting block 9 is fixedly connected to one side of the moving block 602.

[0046] Through the above technical solution, 1. By pulling the clamping component 4 to drive the synchronization component 3 to move, the distance between the clamping components 4 can be adjusted, and the synchronization component 3 drives the reset component 5 to move, and then the grid-connected switch to be detected is placed on the top of the mounting block 2, and the clamping component 4 is released to make the reset component 5 perform a reset movement, the reset component 5 drives the synchronization component 3 to move, and the synchronization component 3 drives the clamping component 4 to move, so that the position of the grid-connected switch is fixed. Since the distance between the clamping components 4 can be adjusted in conjunction with the synchronization component 3, it is convenient to perform grid-connected switches of different models and sizes. 1. The detection is carried out without replacing the detection equipment according to the model of the grid-connected switch, which is time-saving, labor-saving and efficient; 2. By pulling the pull rod 402, the fixed frame 401 fixedly connected at both ends is driven to move. Since one side of the two groups of fixed frames 401 is respectively fixedly connected to one end of the two groups of racks 303, when the fixed frame 401 moves, it can drive the rack 303 fixedly connected on one side to move, and cooperate with the gear 302 to make it move relatively synchronously, and then when the fixed frame 401 moves, it can drive the clamping plate 403 to move relatively, so that it is convenient for it to clamp and fix grid-connected switches of different models.
