The dust collection cylinder 10 is fixed to the top of the power distribution cabinet body 2, and the motor 19 is fixed to the top of the dust collection cylinder 10. The main shaft 33 is set through the dust collection cylinder 10, and the main shaft 33 is rotatably connected to the dust collection cylinder 10 and the power distribution cabinet body 2. The bottom of the inner cavity of the dust collection cylinder 10 is provided with an annular dust collecting groove 32, and a filter plate 29 is fixed to the outer side of the top of the annular dust collecting groove 32.

[0045] Preferably, in order to improve the ventilation and heat dissipation effect, a refrigerator 11 is also installed on the air inlet pipe 12. The refrigerator 11 can absorb the heat in the air in the inner cavity of the air inlet pipe 12. An air cooler, a water cooler, etc. can be used without limitation or elaboration.

[0046] like Figure 1 , 3 , 4, 6 and 7, as a preferred embodiment of the present invention, the double-layer adjustable distribution cabinet also includes an adjustable mounting assembly, which includes a mounting plate 16, a support seat 17, a screw rod 18, a guide rail 19, a motor 24, an arc-shaped telescopic rod 39 and a support plate 40. A screw rod 18 is provided in the middle of the rear side of the distribution cabinet body 2, and the two ends of the screw rod 18 are respectively rotatably connected to the top and bottom of the distribution cabinet body 2. The top of the distribution cabinet body 2 is fixed with a motor 24 that is transmission-connected to the screw rod 18, and the screw rod 18 is threadedly connected to the support seat 17. A guide rail 19 that is slidably connected to the support seat 17 is also fixed on the inner wall of the rear side of the distribution cabinet body 2. A mounting plate 16 is provided on the front side of the support seat 17, and a support plate 40 is vertically fixed to the lower side of the mounting plate 16. The support plate 40 is also connected to the support seat 17 through an arc-shaped telescopic rod 39.

[0047] Preferably, the arc-shaped telescopic rod 39 adopts an arc-shaped structure, and the center of the arc-shaped telescopic rod 39 is located on the abutment line between the upper part of the mounting plate 16 and the support seat 17. The cylinder body of the arc-shaped telescopic rod 39 is embedded and fixed in the support seat 17, and the output end of the arc-shaped telescopic rod 39 is fixedly connected to the support plate 40 to ensure that when the mounting plate 16 is horizontal, the support plate 40 abuts against the surface of the support seat 17 and maintains a stable state.

[0048] Preferably, an inclined surface 38 is provided on the upper portion of the support seat 17, and a second magnet 37 is embedded and fixed in the inclined surface 38. A magnet 1 36 that can be magnetically connected to the second magnet 37 is embedded and fixed on the upper side of one end of the mounting plate 16 close to the support seat 17. When the mounting plate 16 abuts against the inclined surface 38, the magnet 1 36 and the magnet 2 37 are magnetically connected, and at this time, the end of the mounting plate 16 away from the support seat 17 is inclined toward the rear side wall of the distribution cabinet body 2, and the gravity of the mounting plate 16 is used to ensure that the mounting plate 16 is in a stable reception state.

[0049] In specific applications, the arc-shaped telescopic rod 39 can be an ordinary telescopic rod. The mounting plate 16 is pulled to separate the magnet 1 36 and the magnet 2 37, and then the gravity of the mounting plate 16 can be used to make the support plate 40 abut against the surface of the support seat 17. The fixed connection structure of the arc-shaped telescopic rod 39 can ensure that the mounting plate 16 is in a horizontal and stable state, so that the mounting plate 16 can meet the needs of electrical component installation. When the mounting plate 16 needs to be folded, the motor 2 24 can be used to drive the screw rod 18 to rotate, adjust the position of the support seat 17, and then flip the mounting plate 16 upward and abut against the inclined surface 38, and use the magnetic attraction of the magnet 1 36 and the magnet 2 37 and the gravity of the mounting plate 16 itself to ensure the folding stability of the mounting plate 16.

[0050] The present invention provides a double-layer adjustable power distribution cabinet. Through the operation of the fan 23, air is extracted from the air outlet pipe 8 and transported to the air blowing head 5 through the L-shaped air blowing pipe 4 for discharge. At the same time, the return air head 15 inhales air, so that the air in the inner cavity of the power distribution cabinet body 2 can circulate and flow, thereby achieving the purpose of ventilation and heat dissipation. In order to ensure the cleanliness of the air, the air will pass through the L-shaped return air pipe 14 and the air inlet pipe 12 during the circulation process, and the dust filter assembly will perform dust filtration. In particular, the filter plate 29 is responsible for filtering out dust in the air, and the rotation of the main shaft 33 driven by the motor 9 drives the scraper 30 to rotate, effectively scraping off the dust on the inner wall of the filter plate 29, and causing it to fall into the annular dust collecting groove 32, which is convenient for regular cleaning.

[0051] In addition, in order to enhance the heat dissipation effect, the motor 19 can also drive the bevel gear 21 to rotate, and then through the transmission of the bevel gear 20 and the transmission rod 13, the L-shaped blow pipe 4 and the L-shaped return air pipe 14 can be rotated in the opposite direction, which is beneficial for the user to adjust the position of the L-shaped blow pipe 4 and the L-shaped return air pipe 14 as needed, and can also control them to swing back and forth, thereby forming air turbulence inside the distribution cabinet, further improving the heat dissipation effect, and ensuring the stable operation of electrical components in the distribution cabinet.

[0052] The adjustable mounting assembly is additionally defined, and the user can separate the magnet 1 36 and the magnet 2 37 by pulling the mounting plate 16, and use the gravity of the mounting plate 16 to stably support it on the support seat 17; the fixed connection structure of the arc-shaped telescopic rod 39 ensures the horizontal stability of the mounting plate 16, meeting the installation requirements of electrical components. When the mounting plate 16 needs to be folded, the motor 2 24 drives the screw 18 to rotate, adjusts the position of the support seat 17, and then flips the mounting plate 16 upward and abuts against the inclined surface 38; the magnetic attraction of the magnet 1 36 and the magnet 2 37 and the gravity of the mounting plate 16 itself jointly ensure the folding stability of the mounting plate 16.

[0053] In summary, the double-layer adjustable power distribution cabinet of the present invention is optimized in terms of ventilation and heat dissipation effects and adjustment flexibility of the mounting plate 16, thereby ensuring the stability and reliability of electrical components in the power distribution cabinet and improving overall operating efficiency.

[0054] There is no specific limitation on the control, model and circuit connection of each component, which can be flexibly set in practical application. The circuits, electronic components and modules involved are all prior art, and those skilled in the art can fully implement them. It is needless to say that the content protected by the present invention does not involve improvements to software and methods.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
