[0035] Reference Figure 3-4 As shown, a slide groove 15 is provided on the side wall of the cabinet 1, and the slider 8 is I-shaped and slidably connected in the slide groove 15. The exhaust pipe body includes a tee pipe 12 connected to the end of the ventilation pipe 9, one end of the tee pipe 12 is connected to the fixed pipe 13, and the fixed pipe 13 is located on the rear side of the two vertical plates 3, and the other end of the tee pipe 12 is provided with a movable pipe 5, which is connected to the tee pipe 12 through a telescopic hose 501. A plurality of through holes 14 are provided on the opposite sides of the fixed pipe 13 and the movable pipe 5. When the ventilation pipe 9 moves up and down with the chain 703, it drives the slider 8 to slide in the slide groove 15, is connected to the fixed pipe 13 through the tee pipe 12, and the slide rod 502 slides in the ring 503, so that the tee pipe 12 can drive the fixed pipe 13 and the movable pipe 5 to move up and down, and the telescopic hose 501 can ensure the normal delivery of airflow to the movable pipe 5 when it moves.

[0036] Reference Figure 1 and 6As shown, the driving assembly 7 includes a sprocket 701 rotatably connected to the upper and lower sides of the outer wall of the cabinet 1, and the two sprockets 701 are connected by a chain 703.

The rotatable extension rod 704 and the rotating sleeve 706 can ensure that the connecting rope 705 will not be twisted and entangled, and at the same time drive the slider 8 to slide up and down in the slide groove 15.

[0037] Reference Figure 4-5 As shown, the upper and lower sides of the three-way pipe 12 are fixedly connected with collars 503, and the upper and lower sides of the movable pipe 5 are fixedly connected with slide bars 502 slidably connected with the collars 503. The two collars 503 are provided with elastic structures for driving the movable pipe 5 to approach the fixed pipe 13. The elastic structure includes circular plates 504 respectively fixedly connected to the ends of the two slide bars 502. A spring 505 is connected between the circular plate 504 and the collars 503, and the spring 505 is sleeved on the outside of the slide bar 502. When the movable pipe 5 moves up and down, the slide bar 502 slides in the collar 503 under the elastic force of the spring 505, bringing The movable tube 5 moves toward the fixed tube 13, and at the same time, the roller 605 abuts against the surface of the spliced ​​track plate 602, which can ensure that the movable tube 5 is closely fitted with the surface of the power distribution equipment 11 with reference to the spliced ​​track (that is, it moves at the closest point around the power distribution equipment 11), thereby improving the dust collection and exhaust effects. It is worth mentioning that both the fixed tube 13 and the movable tube 5 are designed as thin plastic tubes, so their own weight is relatively low. The tee tube 12, the sliding rod 502 and the ring 503 can stably support the two, and the ends of the fixed tube 13 and the movable tube 5 are both sealed, and the airflow can only flow through the through hole 14.

[0038] Reference Figure 5As shown, the top slide rail 6 includes a perforated plate 601 fixedly connected to the inner wall of the cabinet 1 and a plurality of track plates 602 perpendicular to the surface thereof. The side walls of the track plates 602 are fixedly connected with a plurality of plug rods 603 plugged into the perforated plate 601, and the plug rods 603 and the holes on the perforated plate 601 are mutually engaged. The end of the movable tube 5 is fixedly connected with a support rod 604, and the end of the support rod 604 is rotatably connected with a roller 605 abutting against the track plate 602. The track plate 602 can refer to the power distribution The thickness of the equipment 11 is plugged into a suitable track on the perforated plate 601, and the fixation can be completed by inserting the insertion rod 603 into the perforated plate 601. It is worth mentioning that the track plate 602 can be cut according to the situation, and the support rod 604 can also be cut according to the position of the hole. When the movable tube 5 moves up and down, the roller 605 can abut against the spliced ​​track and move smoothly, ensuring that it fits closely with the surface of the distribution equipment 11 while moving up and down, thereby improving the dust collection and exhaust effects.

[0039] Reference Figure 4 and 8 As shown, the exhaust fan 4 includes a hood 401, a support plate 402 is fixedly connected to the hood 401, a motor fan 403 is fixedly mounted on the support plate 402, one end of the hood 401 is connected to the ventilation pipe 9, and the other end of the hood 401 is connected to the hose 17, the other end of the hose 17 is connected to the bottom of the side wall of the dust collection box 16, a rubber pad 18 is fixedly connected to the bottom opening of the dust collection box 16, and a slit is opened on the rubber pad 18, and both ends of the hood 401 are connected to the ventilation pipe 9. It is conical, which can play a better role in guiding and gathering wind. When the motor fan 403 rotates, it can drive the airflow in the ventilation pipe 9 into the wind cover 401, and finally send it into the oil inside the dust collection box 16 through the hose 17. The rubber pad 18 with a slit can prevent the oil from entering the hose 17. At the same time, when there is airflow, the slit on the rubber pad 18 can ensure the smooth circulation of airflow. It is worth mentioning that the motor fan 403 is a motor with fan blades. This is an existing technology and will not be repeated here.

[0040] Furthermore, a single-chip microcomputer controller 19 and a frequency converter 20 are fixedly installed on the inner wall of the cabinet body 1, and a temperature sensor 21 is fixedly installed on the inner wall of the cabinet door 2. The output end of the temperature sensor 21 is electrically connected to the input end of the single-chip microcomputer controller 19, and the output end of the single-chip microcomputer controller 19 is electrically connected to the input end of the frequency converter 20, and the output end of the frequency converter 20 is electrically connected to the input end of the motor 702 and the motor fan 403. The single-chip microcomputer controller 19 serves as the system core and can receive the sensor signal from the temperature sensor 21, send control instructions (such as start and stop, speed setting, operation mode switching, etc.) to the frequency converter 20 through programming, and receive the status feedback signal of the frequency converter 20. After receiving the instructions from the single-chip microcomputer controller 19, the frequency converter 20 rectifies and inverts the input power supply through the internal circuit, and outputs AC power with adjustable frequency and voltage, thereby driving the variable frequency energy-saving operation of the motor 702 and the motor fan 403.

[0041] The present invention also provides a control cabinet comprising any one of the above industrial power energy-saving control devices.

[0042] Working principle of the present invention:

[0043] When in use, add a proper amount of insulating oil to the dust collection box 16. Then, when the temperature sensor 21 senses that the temperature inside the cabinet 1 has reached a preset value, the single-chip controller 19 controls the frequency converter 20 to drive the motor 702 and the motor fan 403 to rotate at a suitable speed according to the current temperature. When the motor fan 403 rotates, the hot air around the fixed pipe 13 and the movable pipe 5 is sucked into them through the through hole 14, and finally blown into the oil stored in the dust collection box 16 through the three-way pipe 12, the ventilation pipe 9 and the hose 17. The dust and impurities are absorbed by the oil, and the air naturally rises and is discharged. At the same time, the motor 7 02 rotation drives the lower sprocket 701 to rotate, and with the cooperation of the upper sprocket 701, the extension rod 704 moves back and forth with the chain 703, and at the same time drives the slider 8 to slide up and down in the slide groove 15. When the slider 8 slides up and down, the roller 605 at the end of the movable tube 5 abuts against the track plate 602. As the spliced ​​track plate 602 fluctuates, the movable tube 5 can move up and down while fitting the surface of the distribution equipment 11 of different thicknesses, effectively absorbing the heat emitted around the distribution equipment 11, and at the same time, the cold air from the outside enters the cabinet 1 through the slide groove 15 for cooling.
