[0002] The dustproof control cabinet for three-phase asynchronous motors is a specially designed electrical device designed to protect the motor from dust and other environmental pollutants while ensuring the safe and efficient operation of the motor. The control cabinet is equipped with dust filters and other devices to effectively prevent external dust from entering the cabinet and keep the motor and its control components clean.
[0003] To ensure air flow inside the cabinet, ventilation is carried out through devices such as dust filters to isolate external dust. However, after long-term use, dust accumulates on the outside of the dust filters, affecting the temperature inside the cabinet. The dust cannot be dispersed and is difficult to clean. At the same time, the cabinet is cooled by a fan, which can only cool the cabinet in a limited direction, and the range of the flowing wind it blows out is small.

[0035] Reference Figure 1-Figure 3 , a dustproof control cabinet for a three-phase asynchronous motor, comprising: a supporting cabinet 1 for supporting, the top of the supporting cabinet 1 is fixedly connected to a supporting column 3, the front end of the supporting cabinet 1 is rotatably connected to a front cover door 2, both sides of the supporting cabinet 1 are rotatably connected to a placement frame 5, the interior of the placement frame 5 is slidably connected to a mounting plate 8, the interior of the mounting plate 8 is fixedly connected to a dustproof mesh plate 7, the outer side of the mounting plate 8 is fixedly connected to a traction block 9, the two sides of the supporting cabinet 1 are connected to the inner side of the placement frame 5 through a pulling frame to realize the placement frame 5 to be expanded outward, the inner sides of the supporting cabinet 1 are fixedly connected to a cooling fan 14, and the outer side of the placement frame 5 is fixedly connected to an external pull handle 6, refer to Figure 4The pulling frame includes a plurality of fixed seats 12 located inside the placement frame 5, and the interior of the fixed seats 12 are rotatably connected to the traction rods 15, and the two sides of the supporting cabinet 1 are slidably connected to a plurality of slides 16. The inner sides of the traction rods 15 are respectively rotatably connected to the inside of the slides 16, and the interiors of the frames on both sides of the supporting cabinet 1 are fixedly connected to adsorption plates 17. The upper inner side of the placement frame 5 is fixedly connected to a magnetic block 11, and the outer side of the magnetic block 11 is magnetically attracted to the inside of the adsorption plate 17. The inner side of the placement frame 5 is located on the inner side of the fixed seat 12 and is fixedly connected to a limiting plate 10. The inner side of the limiting plate 10 is fixedly connected to a limiting rubber pad 13. The top of the support column 3 is fixedly connected to a rain shield 4 to achieve rain protection for the cabinet.
[0036] When too much dust accumulates on the outside of the dustproof screen 7 due to the traction of the cooling fan 14, the outer pull handle 6 is pushed outward to expand the placement frame 5 outward, and the fixed seat 12 is expanded outward to generate an outward pulling force on the traction rod 15, thereby sliding the slide 16 downward, so that the placement frame 5 is expanded outward. At this time, the mounting plate 8 is lifted upward by the traction block 9, so that the dustproof screen 7 is pulled out for cleaning and replacement, which makes the disassembly of the dustproof screen more convenient and the cleaning more convenient.
[0037] Reference Figure 5 and Figure 6 , used to support the exhaust notches 21 on both sides of the top of the cabinet 1, the exhaust channels 22 are opened on both sides of the interior of the support column 3, the bottom end of the exhaust channel 22 corresponds to the exhaust notches 21, and the wind shields are installed on both sides of the interior of the supporting cabinet 1 to achieve uniform cooling inside the supporting cabinet 1, refer to Figure 7 The hood includes a traction hood 19 located on both sides of the interior of the supporting cabinet 1. A plurality of cooling slots 20 are evenly opened on the inner side of the traction hood 19. The cooling fans 14 are all located at the lower side of the traction hood 19. The outer side of the exhaust duct 22 is fixedly connected with a dustproof net strip 18 to achieve dustproof at the air outlet;
[0038] Start the cooling fan 14 to quickly pull the external air into the supporting cabinet 1. The cooling fan 14 accelerates the flow of wind to contact the inner side of the traction hood 19. Figure 4It can be seen that the cooling fan 14 is located below the two sides of the supporting cabinet 1. The flowing wind blown inward by the cooling fan 14 contacts the inside of the traction hood 19. Because the lower side of the traction hood 19 cannot be ventilated, and because of the traction and squeezing of the cooling fan 14, the flowing wind will flow upward along the traction hood 19, and then be discharged to the outside through multiple cooling slots 20, thereby expanding the cooling range inside the device. The cooling flowing wind will flow upward along the exhaust slot 21. Because the warm air is lighter, it is discharged to the outside through the exhaust duct 22, thereby completing the internal cooling, making the cooling effect inside the cabinet better, and ensuring the long-term use of the internal control components.
[0039] Working principle: Start the cooling fan 14 to quickly draw the external air into the supporting cabinet 1. The cooling fan 14 accelerates the flow of wind to contact the inner side of the traction hood 19. Figure 4 It can be seen that the cooling fan 14 is located below the two sides of the supporting cabinet 1. The flowing wind blown inward by the cooling fan 14 contacts the inside of the traction hood 19. Because the lower side of the traction hood 19 cannot be ventilated, and because of the traction and extrusion of the cooling fan 14, the flowing wind will flow upward with the traction hood 19, and then be discharged to the outside through multiple cooling slots 20, thereby expanding the range of cooling inside the device. The cooling flowing wind will flow upward along the exhaust slots 21. Because the heating is lighter, it will be discharged through the exhaust slots 21. The air duct 22 is discharged to the outside, thereby completing the internal cooling. When too much dust accumulates on the outside of the dustproof screen 7 due to the traction of the cooling fan 14, the outer pull handle 6 is pushed outward to expand the placement frame 5 outward. The outward expansion of the fixed seat 12 generates an outward pulling force on the traction rod 15, thereby sliding the slide 16 to the downward side, thereby expanding the placement frame 5 outward. At this time, the mounting plate 8 is lifted upward by the traction block 9, thereby pulling out the dustproof screen 7 for cleaning and replacement.
[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
