[0003] A distribution cabinet with an expansion function with the publication number of CN220754078U. The cooperation between the top plate and the bottom plate of this device can expand the capacity of the distribution cabinet to form the required distribution cabinet capacity. Under the action of the splicing structure, the height and the use width of the distribution cabinet can be expanded and spliced. Through the setting of the door frame assembly, it is convenient to assemble the corresponding door frame for the expanded distribution cabinet and install the electric cabinet door required for the distribution cabinet, improving the overall use effect and usability.

The left end of the drive motor 9 is connected to a first bevel gear 10 through a rotating shaft. A second bevel gear 11 is meshed with the top of the first bevel gear 10. The top of the second bevel gear 11 is connected to a threaded rod 12, and the top of the threaded rod 12 is connected to the threaded sleeve 13. A closing door 3 is connected to the front of the first housing 1 and the second housing 2;

[0037] When using a power distribution cabinet with an expansion function, first connect the device power supply to the power grid for power supply. Then start the drive motor 9, so that the drive motor 9 drives the first bevel gear 10 to rotate through the rotating shaft, thereby causing the first bevel gear 10 to drive the second bevel gear 11 to rotate, and the second bevel gear 11 drives the threaded rod 12 to rotate. At this time, the threaded rod 12 will rotate inside the threaded sleeve 13, so that the second housing 2 is driven by the threaded sleeve 13 to move up and down, and the second housing 2 slides inside the top of the protective housing 5. It can make the protective housing 5 protect the second housing 2 during the lifting process;

[0038] A base 14 is connected to the bottom of the first housing 1, and the base 14 is fixedly connected to the first housing 1. And a fixing seat 15 is connected to the top of the base 14, and the top of the fixing seat 15 is fixedly connected to the bottom of the protective housing 5; A rain shelter 16 is connected to the top of the second housing 2, and the rain shelter 16 is located on the top of the protective housing 5; A sealing ring 7 is connected to the top of the protective housing 5, and a sealing gasket 8 is provided on the top of the protective door 6, and the sealing ring 7 is in contact with the sealing gasket 8; A connecting plate 4 is provided in the middle of the closing door 3, and the connecting plate 4 is slidably connected to the inside of the closing door 3;

[0040] Embodiment 2:

[0041] In this embodiment, a heat dissipation method is disclosed, which is different from Embodiment 1. Specifically, as Figures 5-6 shown, the difference between this embodiment and Embodiment 1 is that: a first sprocket 17 is connected to the left end of the drive motor 9, and a chain 18 is meshed with the outside of the first sprocket 17, and a second sprocket 19 is meshed with the top of the chain 18. The right end of the second sprocket 19 is connected to a ventilation fan 20, and an electric push rod 21 is connected to the left end of the drive motor 9 and meshed with the rotating shaft; A ventilation opening 22 is provided at the right end of the ventilation fan 20, and the ventilation opening 22 is located at the right end of the bottom of the first housing 1;

[0042] Disconnect the electric push rod 21 from the rotating shaft, and then start the drive motor 9, so that the drive motor 9 drives the first sprocket 17 to rotate, and the first sprocket 17 drives the chain 18 and the second sprocket 19 to rotate, so that the second sprocket 19 drives the ventilation fan 20 to rotate to ventilate and dissipate heat from the power distribution cabinet composed of the first housing 1 and the second housing 2.

[0043] Embodiment 3:

An anti-corrosion layer is provided on the outer side of the protective shell 5, and the top of the protective shell 5 and the sealing ring 7 form an integrated mechanism.

[0045] Working principle: When using a power distribution cabinet with an expansion function, first connect the device power supply to the power grid for power supply, and then start the drive motor 9, so that the drive motor 9 drives the first bevel gear 10 to rotate through the rotating shaft, thereby causing the first bevel gear 10 to drive the second bevel gear 11 to rotate, and the second bevel gear 11 drives the threaded rod 12 to rotate. At this time, the threaded rod 12 will rotate inside the threaded sleeve 13, so that the second shell 2 is driven by the threaded sleeve 13 to move up and down, and the second shell 2 slides inside the top of the protective shell 5. It can be ensured that during the lifting process of the second shell 2, the protective shell 5 protects it.

[0046] When the user fixes the device, the bottom of the first shell 1 can be fixed through the base 14, and then the fixing seat 15 provided on the top of the base 14 is fixedly connected to the protective shell 5, so as to fix the protective shell 5.
