[0030] Based on the above objectives, one or more embodiments of this specification provide a multifunctional AC low-voltage power distribution cabinet, characterized in that it includes:

[0031] The power distribution cabinet 1 has two opposite side walls with a ventilation hole respectively, and a ventilation fan 2 is provided inside the ventilation hole. The rotating shaft of the ventilation fan 2 extends into the power distribution cabinet 1 and a first bevel gear 3 is fixed to the end thereof;

[0032] There are two rotating rods 4 provided longitudinally. The two rotating rods 4 are movably arranged in the control box beside the ventilation hole. The second bevel gear 5 is fixed to the end of the bottom end. The third bevel gear 6 and the fourth bevel gear 7 are fixed on the rotating rods 4 on both sides of the first bevel gear 3. The third bevel gear 6 is located on the lower side of the fourth bevel gear 7. A vibration disc 8 is fixed on the rotating rod 4 on the lower side of the third bevel gear 6. A plurality of first vibration blocks 9 are fixed to the outer side of the vibration disc 8.

[0033] A dustproof net 10 is provided at the mouth of each ventilation hole. A pulling block 11 is fixed to the lower end of the dustproof net 10. A side of the pulling block 11 is recessed with an arc-shaped groove, and a plurality of second vibration blocks 12 are fixed in the groove. The groove is close to the outer side of the rotating rod 4.

[0034] The driving rod 13 is rotatably arranged at the bottom end of the distribution cabinet 1, and a driving bevel gear 14 is fixed to the end of each end. The driving bevel gear 14 is respectively engaged with the second bevel gear 5 on both sides. The middle part of the driving rod 13 is provided with a double-headed motor 15, and the lower end of the double-headed motor 15 is fixed on the lifting frame 16.

[0035] The present invention provides a multifunctional AC low-voltage distribution cabinet, which opens ventilation holes on the opposite sides of the distribution cabinet body 1, and a dustproof net 10 is arranged in the ventilation hole. The bottom end of the dustproof net 10 is connected to a pulling block 11. During heat dissipation, the fourth bevel gear 7 on the rotating rod 4 is engaged with the first bevel gear 3, driving the ventilation fan 2 to rotate forward to blow the external cold air into the distribution cabinet body 1 for heat dissipation. The dustproof net 10 is used to block impurities such as dust. During cleaning, the driving rod 13 drives the rotating rod 4 at both ends to rise through the lifting frame 16, and the third bevel gear 6 is engaged with the first bevel gear 3 to make the ventilation fan 2 reverse, and the vibrating disc 8 is at the same height and in contact with the pulling block 11. The first vibrating block 9 of the vibrating disc 8 rotates to hit the second vibrating block 12 of the pulling block 11, thereby causing the dust and impurities on the dustproof net 10 to fall off, and the ventilation fan 2 reverses to blow out the dust and impurities, effectively preventing the dust and impurities from being sucked into the distribution cabinet body 1, and eliminating the safety hazards caused by dust.

[0036] As an optional embodiment, the rotating rod 4 is slidably sleeved with a receiving tube 17 on the sides near the upper and lower ends, and a receiving rod 18 is fixed to the side of each receiving tube 17, and the other end of the receiving rod 18 is fixed to the side wall of the distribution cabinet 1.

[0037] The receiving tube 17 is used to support the rotation of the rotating rod 4 so that the rotating rod 4 does not deflect.

[0038] As an optional embodiment, the cone portions of the third bevel gear 6 and the fourth bevel gear 7 are opposite to each other.

[0039] The conical parts of the third bevel gear 6 and the fourth bevel gear 7 are opposite to each other, so that when the rotating rod 4 moves up and down, the third bevel gear 6 and the fourth bevel gear 7 are respectively engaged with the first bevel gear 3.

[0040] As an optional embodiment, a through hole 19 is opened on the ventilation hole side wall on the lower side of the dustproof net 10, and a sliding hole 20 is passed through the bottom end of the through hole 19 into the distribution cabinet 1, and the pulling block 11 is slidably set in the sliding hole 20.

[0041] The pulling block 11 slides horizontally in the sliding hole 20 and will not fall out of the sliding hole 20 .

[0042] As an optional implementation, a magnetic ring 21 is embedded in the vibration disc 8 , and a magnetic block 22 is embedded in the corresponding pulling block 11 .

[0043] Specifically, the first vibration block 9 and the second vibration block 12 are both hemispherical.

[0044] When the vibrating disc 8 and the pulling block 11 are at the same height and in contact, the magnetic ring 21 and the magnetic block 22 attract each other, so that the vibrating disc 8 and the pulling block 11 attract each other. When the vibrating disc 8 rotates, the first vibrating block 9 continuously hits the second vibrating block 12, so that the pulling block 11 continuously slides back and forth under the magnetic attraction, and continuously shakes the dustproof net 10 to shake off dust and impurities, and then blows out the dust and impurities through the ventilation fan 2.

[0045] As an optional embodiment, a dust hopper 23 is movably provided on the outside of each ventilation hole. The top of the dust hopper 23 is rotatably set on the outer wall of the distribution cabinet 1 near the end of the distribution cabinet 1. The dust hopper 23 is connected to a telescopic tube 24, and the other end of the telescopic tube 24 is connected to a dust collecting box 25. The dust collecting box 25 is fixed on the outer wall of the distribution cabinet 1 next to the ventilation hole. The top of the dust hopper 23 is connected to the end away from the distribution cabinet 1 with a pull rope 26.

[0046] Specifically, a rotating disk 27 is rotatably provided at the top end of the rotating rod 4, and a socket block 28 is provided on the rotating disk 27. A rotating groove with an opening is opened in the socket block 28. The rotating disk 27 is movably set in the rotating groove, and the top end of the socket block 28 pulls the other end of the pull rope 26.

[0047] When cleaning dust, the rotating rod 4 moves upward so that the third bevel gear 6 engages with the first bevel gear 3. At the same time, the rotating rod 4 rises so that the socket block 28 rises, and the dust hopper 23 is able to fall and cover the ventilation hole. The blown dust and impurities are collected into the dust collecting box 25 through the telescopic tube 24; when cooling, the rotating rod 4 descends so that the fourth bevel gear 7 engages with the first bevel gear 3. At the same time, the rotating rod 4 drives the pull rope 26 to retract, and the pull rope 26 pulls the dust hopper 23 to rotate and disengage from the ventilation hole, so that the air inlet of the ventilation hole is unobstructed.

[0048] Among them, the dust hopper 23 and the telescopic tube 24 are made of lightweight materials and will not affect the up and down movement of the rotating rod 4. A through hole is opened in the distribution cabinet 1 on the upper side of the ventilation hole, and the pull rope 26 passes through the through hole to pull the dust hopper 23 and the socket block 28.

[0049] As an optional implementation, a support frame 29 is fixed to the bottom end of the power distribution cabinet 1 .

[0050] As an optional implementation, a wiring tube 30 is fixed on the inner wall of the power distribution cabinet 1 .
