Problems solved by technology

[0003] When the components in the power distribution cabinet work, they will generate heat, so heat dissipation is required. The existing power distribution cabinets generally use fixedly installed fans to dissipate heat. The heat dissipation range is small and the effect is poor.

Embodiment 1

[0023] see Figure 1~2 , in an embodiment of the present invention, a rotary heat dissipation power distribution cabinet includes a cabinet body 1 and a heat dissipation unit for cooling components in the cabinet body 1. The bottom of the cabinet body 1 is evenly and symmetrically fixed with rollers 11, which is convenient For the movement of the device, cabinet doors are detachably installed on the cabinet body 1. In this embodiment, the cabinet doors are preferably connected to the cabinet body 1 through hinges and hasps, and ventilation nets can be detachably installed on both side walls of the cabinet body 1. 12. The heat dissipation unit includes a hollow shaft 20, a driving mechanism 19 for driving the hollow shaft 20 to rotate, a fan 22 whose air outlet communicates with the hollow shaft 20, a two-way screw rod 18, an internal thread sleeve 21, a heat dissipation pipe 15 and a sliding rod 13. The hollow shaft 20 vertically runs through the top of the cabinet body 1 and ...

Embodiment 2

[0026] see image 3 The difference between this embodiment of the present invention and Embodiment 1 is that in order to prevent the fan 22 from sending a large amount of dust into the cabinet 1, a filter assembly is installed at the air inlet 23 of the fan 22, and the filter assembly includes a third Motor 27, dust-proof net 26 and hairbrush bar 28, described third motor 27 is fixedly installed on the shell lower surface of blower fan 22, is fixed with dust-proof net 26 on the output shaft of the 3rd motor 27, and the top of dust-proof net 26 Block the air inlet 23 of the fan 22, the bottom side of the dust-proof net 26 is fixedly equipped with a brush bar 28, and the brush of the brush bar 28 contacts with the dust-proof net 26. In the present embodiment, the brush Bar 28 is fixedly installed on the bottom of the third motor 27, and the third motor 27 drives the dust-proof net 26 to rotate, and the dust-proof net 26 can filter the wind entering the air inlet 23. 26 carries ou...

Abstract

The invention discloses a rotary heat dissipation power distribution cabinet, relates to the technical field of power equipment, and mainly aims to solve the problem of poor heat dissipation effect ofan existing power distribution cabinet. The power distribution cabinet comprises a cabinet body and a heat dissipation unit used for dissipating heat of elements in the cabinet body. Each heat dissipation unit comprises a hollow shaft, a driving mechanism used for driving the hollow shaft to rotate, a draught fan with an air outlet communicating with the hollow shaft, a two-way lead screw, an inner threaded sleeve, a heat dissipation pipe and a sliding rod. The lower part of the inner cavity of the cabinet body is slidably connected with a mounting plate for mounting elements; a damping unitis connected between the mounting plate and the bottom of the inner cavity of the cabinet body; each damping unit comprises a second motor, a damping gear, a movable rod, a first sliding sleeve, a guide rod and a compression spring. The heat dissipation unit is arranged, air cooling heat dissipation is conducted on the element by 360 degrees, the heat dissipation effect is good, the air blowing angle of a nozzle of the heat dissipation pipe is continuously changed, the air cooling heat dissipation range is enlarged, the heat dissipation efficiency is further improved, the damping unit is arranged, the compression amount of the compression spring is adjusted, and then the damping efficiency is adjusted.

Description

technical field [0001] The invention relates to the technical field of power equipment, in particular to a rotating power distribution cabinet for heat dissipation. Background technique [0002] Power distribution cabinets (boxes) are divided into power distribution cabinets (boxes), lighting distribution cabinets (boxes), and metering cabinets (boxes), which are the final equipment of the power distribution system. The power distribution cabinet is a general term for the motor control center. The power distribution cabinet is used in the occasions where the load is relatively scattered and there are few circuits; the motor control center is used in the occasions where the load is concentrated and there are many circuits. They distribute the electric energy of a certain circuit of the upper-level power distribution equipment to the nearest load. This level of equipment shall provide protection, monitoring and control of the load. [0003] When the components in the power ...
