Description

Technical Field

[0001] The utility model relates to the field of three-phase asynchronous motors, in particular to a stainless steel three-phase asynchronous motor. Background Art

[0002] The speed of the rotor of a three-phase asynchronous motor is lower than the speed of the rotating magnetic field. The rotor winding generates electromotive force and current due to the relative motion between the rotor winding and the magnetic field, and interacts with the magnetic field to generate electromagnetic torque, thereby realizing energy conversion.

[0003] A search of the patent document with publication number CN216721083U discloses "a heat-dissipating three-phase asynchronous motor. This device is connected to the interior of the three-phase asynchronous motor body via through slots and grooves. By activating fans within two heat-dissipating frames, the circulation of air between the three-phase asynchronous motor body and the outside air can be accelerated, thereby improving the heat dissipation effect of the three-phase asynchronous motor body and minimizing overheating of the three-phase asynchronous motor body that could cause damage to components."

[0004] After long-term use, this heat-dissipating three-phase asynchronous motor will be pulled by the wind for a long time, and floating objects or dust in the air will be attracted by the filter structure. As a result, the filter structure will be easily clogged after a long period of heat dissipation. When the filter structure is clogged to a certain extent, the internal fluidity will be affected, thereby affecting its heat dissipation effect. Utility Model Content

[0027] The present invention will be further described below with reference to the accompanying drawings:

[0028] like Figures 1-6 As shown, a stainless steel three-phase asynchronous motor includes a base frame 1, a connecting mechanism is installed on the upper end of the base frame 1, a three-phase asynchronous motor body 4 is installed on the upper end of the connecting mechanism, and the three-phase asynchronous motor body 4 is a stainless steel three-phase asynchronous motor, and also includes a heat dissipation mechanism for dissipating heat inside the device.

[0029] In this embodiment, bottom plates 11 are fixed to the front and rear ends of the bottom frame 1 , and two fixing bolts 12 are provided in the middle of the bottom plate 11 ; the device can be installed in a suitable position by the fixing bolts 12 .

[0030] In this embodiment, the heat dissipation mechanism includes an exhaust fan 2, which is installed inside one end of the bottom frame 1, and an exhaust fan 21 is installed inside the other end of the bottom frame 1. Filter plates 22 are fixed at both ends of the bottom frame 1, and sliders 23 are provided below the two filter plates 22. The length of the through groove of the bottom frame 1 for sliding the slider 23 is the same as the length of the filter plate 22, and the slider 23 is slidably connected to the bottom frame 1. A first cleaning brush 24 is fixed to one end of the slider 23, a handle is fixed to one end of the first cleaning brush 24, and a second cleaning brush is fixed to the other end of the slider 23. 25, the filter plate 22 is located in the middle of the corresponding second cleaning brush 25 and the first cleaning brush 24, and the bristles of the first cleaning brush 24 and the second cleaning brush 25 are facing the corresponding filter plate 22. Two springs 26 are fixed inside both ends of the bottom frame 1, and one end of the spring 26 is fixed with a discharge rack 27. The discharge rack 27 is slidably connected to the bottom frame 1, and the corresponding ends of the two corresponding discharge racks 27 are fixed with a convex plate, and one end of the discharge rack 27 is fixed with a pull ring 28; when it is necessary to dissipate heat in the device, start the exhaust fan 21 and the filter plate 22, The exhaust fan 21 exhausts the hot air in the device, and the filter plate 22 draws the air outside the device into the device, thereby performing heat dissipation treatment on the device. After the device has been used for a long time, if the dust adhering to the surfaces of the two filter plates 22 is likely to affect the heat dissipation in the device, the slider 23 is connected to the bottom frame 1 by sliding, and the handle on the first cleaning brush 24 is pulled, so that the first cleaning brush 24 and the second cleaning brush 25 on the slider 23 move accordingly, so that the first cleaning brush 24 and the second cleaning brush 25 can remove the dust adhering to the surface of the filter plate 22. Cleaning is carried out, which can facilitate the cleaning of the filter plate 22, thereby preventing the blockage of the filter plate 22 from affecting the heat dissipation in the device, and the dust on the inner surface of the filter plate 22 is swept by the second cleaning brush 25. In this way, the dust accumulated and adhered to the inner surface of the filter plate 22 is swept down to one end of the slide groove opened by the corresponding slider 23 of the bottom frame 1, and then the corresponding pull ring 28 is pulled to pull out the discharge rack 27, so that the convex plate on the discharge rack 27 discharges the dust accumulated in the slide groove, thereby preventing the dust accumulated in the slide groove from affecting the sliding of the slider 23.

[0031] In this embodiment, the connecting mechanism includes a top plate 3, which is arranged at the upper end of the bottom frame 1. Connecting bolts 31 are provided at the four corners of the top plate 3. The bottom frame 1 is provided with threaded holes corresponding to the positions of the connecting bolts 31 on the top plate 3. The top plate 3 is fixed to the bottom frame 1 through the connecting bolts 31. The upper ends of both sides of the connecting bolts 31 are fixed with limit rings 32, and the three-phase asynchronous motor body 4 is installed in the middle of the two limit rings 32; the top plate 3 can be removed by unscrewing the connecting bolts 31, thereby facilitating the maintenance or replacement of components in the bottom frame 1.

[0032] Working principle: When the heat inside the device needs to be dissipated, the exhaust fan 21 and the filter plate 22 are started. The exhaust fan 21 discharges the hot air inside the device, and the filter plate 22 draws the air outside the device into the device, thereby dissipating the heat inside the device. After the device has been used for a long time, if the dust accumulated on the surface of the two filter plates 22 is likely to affect the heat dissipation inside the device, the slider 23 is connected to the bottom frame 1, and the handle on the first cleaning brush 24 is pulled to move the first cleaning brush 24 and the second cleaning brush 25 on the slider 23, thereby making the first cleaning brush 24 and the second cleaning brush 25 move together. The brush 25 cleans the dust attached to the surface of the filter plate 22, which makes it easier to clean the filter plate 22, thereby preventing the blockage of the filter plate 22 from affecting the heat dissipation in the device. The dust on the inner surface of the filter plate 22 is swept by the second cleaning brush 25, so that the dust accumulated on the inner surface of the filter plate 22 is swept down to one end of the slide groove opened by the corresponding slider 23 of the bottom frame 1, and then the corresponding pull ring 28 is pulled to pull out the discharge rack 27, so that the convex plate on the discharge rack 27 discharges the dust accumulated in the slide groove, thereby preventing the dust accumulated in the slide groove from affecting the sliding of the slider 23.
