[0024] The following description is used to disclose the utility model so that those skilled in the art can implement the utility model. The preferred embodiments in the following description are only examples, and those skilled in the art can think of other obvious variants.

[0025] Referring to Figures 1-5 As shown, a distributed photovoltaic power generation grid-connected distribution cabinet includes a distribution cabinet body 1. A plurality of symmetrically distributed fixed frames 2 are fixedly connected to the left and right inner walls of the distribution cabinet body 1. A slide groove 3 is opened inside the fixed frame 2. A connecting plate 4 is slidably connected inside the slide groove 3. A placement plate 5 is fixedly connected between the two connecting plates 4. Telescopic grooves 6 are opened at the top and bottom inside the slide groove 3. At least one spring 7 is fixedly connected inside the telescopic groove 6. One end of the spring 7 close to the opening of the telescopic groove 6 is fixedly connected to a telescopic block 8. The telescopic block 8 is slidably connected inside the telescopic groove 6. One end of the telescopic block 8 away from the spring 7 is fixedly connected to a card block 10. Card slots 9 are opened at the corresponding positions of the upper and lower ends of the connecting plate 4 and the card block 10. The card block 10 is inserted into the card slot 9. A plurality of groups of uniformly distributed wire grooves 13 are opened through the rear part of the upper end of the placement plate 5. Wire clamps 12 are fixedly connected to the front side of each group of wire grooves 13 at the upper end of the placement plate 5.

[0026] Furthermore, a handle groove 11 is opened at the front part of the lower end of the placement plate 5. The handle groove 11 provides a convenient grasping point, facilitating the disassembly and installation of the placement plate 5 and improving the operation convenience.

[0027] Furthermore, one end of the card block 10 close to the telescopic block 8 is flush with the opening of the telescopic groove 6. The cross-sections of the card block 10 and the card slot 9 along the sliding direction of the slide groove 3 are triangles with the same size.

[0028] Further, the placement board 5 is used to install electrical equipment, and its quantity and position can be adjusted according to the actual usage situation. By inserting the connecting plates 4 on both sides of the placement board 5 into different sliding grooves 3, the layout of the internal space of the distribution cabinet body 1 can be adjusted to adapt to different scales or types of photovoltaic equipment and electrical equipment, which not only enhances the adaptability of the distribution cabinet body 1, but also enables the more effective utilization of the internal space of the distribution cabinet body 1. During the process of inserting the connecting plate 4 into the sliding groove 3, the clamping block 10 will be pressed by the pressure and squeezed into the telescopic groove 6. When the connecting plate 4 is fully inserted, the clamping block 10 is aligned with the clamping groove 9. At this time, the clamping block 10 is reset under the elastic force of the spring 7 and inserted into the inside of the clamping groove 9 to lock it, thus completing the installation of the placement board 5. If it is necessary to take out the placement board 5, it is necessary to hold the handle groove 11 with the hand and then apply a certain external force to pull the placement board 5 outward, so that the clamping groove 9 squeezes the clamping block 10 to shrink it into the telescopic groove 6, and the locking can be released, and then the placement board 5 can be pulled out.

[0029] Further, each group of wire grooves 13 includes several wire grooves 13 arranged evenly along the sliding direction of the sliding groove 3. When connecting the cables, in accordance with the arrangement order of the placement boards 5 from bottom to top, the corresponding cables are passed through the corresponding number of wire grooves 13 from front to back. After passing through the wire grooves 13, the cables are fixed by the wire clips 12 and then connected to the electrical equipment. By arranging the cables in the wire grooves 13 in sequence, the crossing and winding of the cables can be effectively avoided, the internal space can be kept clean, and the overall aesthetics can be improved. At the same time, the clear cable layout makes the daily maintenance and management more convenient, facilitates the identification and troubleshooting of problems, reduces the maintenance difficulty, and the use of the wire clips 12 ensures the fixation of the cables, prevents the cables from loosening or falling off due to vibration or other external forces, and enhances the safety of the distribution cabinet body 1 during use.

[0030] Further, the clamping part of the wire clip 12 is made of an elastic material. Using an elastic material to make the clamping part of the wire clip 12 can enable the clamping part to generate deformation within a certain range, can adapt to cables with different diameters and shapes, and enables the clamping part to effectively fit with various types of cables, ensuring the stable fixation of the cables.

[0031] Refer to Figure 1 and Figure 6 As shown, a plurality of uniformly distributed inlet ports 14 are penetrated and opened at the inner bottom end of the distribution cabinet body 1, and a cabinet door 15 is hinged to the front end of the distribution cabinet body 1. The inlet ports 14 are used to introduce external power supply cables.

[0032] Working principle: During the installation process, the user can adjust the position of the placement plate 5 by inserting the connecting plate 4 into different sliding grooves 3 according to the usage requirements, so as to adapt to photovoltaic devices and electrical devices of different scales or types. The flexible layout of the placement plate 5 can effectively utilize the internal space of the power distribution cabinet body 1. When the connecting plate 4 is inserted into the sliding groove 3, the clamping block 10 is pressed and squeezed into the telescopic groove 6. When the connecting plate 4 is completely inserted, the clamping block 10 is reset under the elastic force of the spring 7 and inserted into the clamping groove 9 to complete the locking of the placement plate 5. The external power cable is introduced into the interior of the power distribution cabinet body 1 through the cable inlet 14. When connecting the cable, the cable passes through the wire grooves 13 in sequence according to the arrangement order of the placement plate 5 and is fixed by the wire clips 12 to avoid entanglement and crossing, keep the internal space clean, facilitate daily maintenance and fault troubleshooting, and reduce the maintenance difficulty. Since the clamping part of the wire clip 12 is made of elastic material, it can adapt to cables of different diameters, effectively fix the cables, and increase the safety and adaptability of the power distribution cabinet.
