Description

Technical Field

[0001] This utility model relates to the field of switchgear technology, specifically to a switchgear wiring device for photovoltaic power generation. Background Technology

[0002] For photovoltaic grid-connected power generation systems on the low-voltage distribution network side, electricity needs to be connected to the grid through switchgear. Switchgear refers to a complete set of power distribution equipment assembled with primary and secondary equipment according to a certain circuit scheme, which is used to control and protect the lines and equipment.

[0003] Currently, cables used in switch cabinets typically require clamping and bundling. Existing cable bundling devices generally use fixed clips for bundling, and once the clip position is fixed, it is inconvenient to adjust the clip position arbitrarily. Moreover, the inner diameter of the cable bundle in existing cable bundling devices is not easy to adjust, which means that it cannot be adjusted according to the number of cables bundled, resulting in limited use and low applicability. Utility Model Content

[0004] The purpose of this utility model is to provide a switchgear wiring device for photovoltaic power generation to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a switchgear wiring device for photovoltaic power generation, including a mounting plate, and further comprising:

[0006] A limiting shell is fixed to the rear side of the mounting plate. Both sides of the limiting shell are provided with extension plates. The front side of the mounting plate is fixedly connected to the limiting plate. A sliding groove is opened on one side of the limiting plate. Multiple sliding blocks are provided inside the sliding groove.

[0007] A connecting post is fixed to the front side of the sliding block, and a wire harness is provided on one side of the connecting post. The wire harness includes an extension frame and a screw.

[0021] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0022] Please see Figure 1-4 As shown, a photovoltaic power generation switch cabinet wiring device includes a mounting plate 1 and a limiting shell 2 fixed to the rear side of the mounting plate 1. Both sides of the limiting shell 2 are provided with extension plates 3, which can be used to conveniently fix the mounting plate 1 in conjunction with the limiting shell 2. A limiting plate 4 is fixedly connected to the front side of the mounting plate 1. A sliding groove 5 is provided on one side of the limiting plate 4, which can be used to conveniently adjust the position of the sliding block 6. Multiple sliding blocks 6 are provided inside the sliding groove 5.

[0023] A connecting post 7 is fixed to the front side of the sliding block 6. A wire harness 8 is provided on one side of the connecting post 7. The wire harness 8 includes an extension frame 801 and a screw 802.

[0024] The extension plate 3 has multiple mounting holes 9 for positioning, which facilitates the installation and fixing of the extension plate 3. The bottom of the mounting plate 1 has slots 10, which facilitate the connection of auxiliary wires to cables. The top of the limiting plate 4 is fixedly connected to a reinforcing block 11. The fixed connection between the reinforcing block 11 and the mounting plate 1 can improve the connection strength between the limiting plate 4 and the mounting plate 1. One side of the reinforcing block 11 is fixedly connected to the mounting plate 1.

[0025] A positioning plate 12 is fixedly connected to the bottom of the sliding block 6. A spring 13 is fixedly connected to one side of the positioning plate 12. A positioning ring 14 is fixedly connected to one side of the spring 13. A limiting rod 15 is fixedly connected to one side of the positioning ring 14. The end of the limiting rod 15 away from the positioning ring 14 passes through to one side of the positioning plate 12 and is fixedly connected to an insert 16. A slot 17 for use with the insert 16 is arrayed on one side of the mounting plate 1. Pulling the positioning ring 14 causes the limiting rod 15 to move the insert 16 away from the slot 17. At this time, the spring 13 will also be forced to retract. Then the sliding block 6 can be moved to adjust the positioning angle. A limiting groove 18 for positioning the sliding block 6 is opened at the top of the inner cavity of the slide groove 5. The limiting groove 18 can prevent the sliding block 6 from leaving the interior of the slide groove 5. Openings for inserting the sliding block 6 are opened on both sides of the top of the limiting plate 4.

[0026] The extension frame 801 is fixed to both sides of the connecting column 7. The screw 802 is rotatably connected to the inside of the extension frame 801. A retaining ring 803 is fixedly connected to one side of the screw 802. A torsion block 804 is fixedly connected to the end of the screw 802 away from the retaining ring 803. A slide rod 805 is fixedly connected to one side of the retaining ring 803. When the user needs to adjust the distance between the two retaining rings 803, the two screws 802 are rotated inside the extension frame 801 by twisting the two torsion blocks 804, which causes the two retaining rings 803 to move relative to each other. When the retaining rings 803 move, the slide rod 805 will also move relative to each other to bind and position the cable. The end of the slide rod 805 away from the retaining ring 803 extends to the outside of the extension frame 801.

[0027] Working principle: First, the extension plate 3 can be adjusted inside the limiting shell 2, so that the mounting plate 1 can be easily positioned through the mounting hole 9 on the extension plate 3. Then, the sliding block 6 can be limited by the sliding groove 5 and the limiting groove 18. However, if the position of the cable needs to be adjusted during use, the positioning ring 14 can be pulled to make the limiting rod 15 move the insert 16 away from the slot 17. At this time, the spring 13 will also be forced to retract. Then the sliding block 6 can be moved to adjust the positioning angle. When the user needs to adjust the distance between the two retaining rings 803, the two screws 802 can be rotated inside the extension frame 801 by twisting the two torsion blocks 804, so that the two retaining rings 803 can move relative to each other. When the retaining rings 803 move, the sliding rod 805 will also move relative to each other to bind and position the cable.

[0028] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
