Description

Technical Field

[0001] The invention relates to the technical field of three - phase asynchronous motors, and specifically to a three - phase asynchronous motor with a fast cooling function. Background Art

[0002] A three - phase asynchronous motor is an induction motor that relies on being powered by simultaneously connecting to a 380V three - phase alternating current (with a 120 - degree phase difference). Its rotor rotates in the same direction as the stator rotating magnetic field but at a different speed, with a slip rate, so it is called a three - phase asynchronous motor. A three - phase asynchronous motor mainly consists of two parts: a stator and a rotor. The stator is the stationary part, mainly including a stator core and a stator winding; the rotor is the rotating part, including a rotating shaft, a rotor core, a rotor bracket, and a rotor winding, etc. In addition, the motor also includes components such as a machine base, end covers, bearings, and fans.

[0003] A three - phase asynchronous motor with a fast cooling function published according to a Chinese patent, with a publication number of CN216530969U, includes a machine cover, a bracket, and a junction box. One end of the machine cover is installed with a mesh cover through bolts. A wind plate is welded inside the mesh cover. A stator is installed inside the machine cover. A rotor is arranged inside the stator. One end of the rotor is installed with a main shaft, and the other end of the rotor is installed with a rotating shaft. Bearings are sleeved on the outer sides of both the main shaft and the rotating shaft. A clamping cover is sleeved on the outer side of the bearing. This three - phase asynchronous motor with a fast cooling function can ventilate the inner and outer sides of the stator, quickly dissipate the generated heat outward, reduce the working temperature of the motor, ensure the safety of the motor, the fan blades can rotate continuously, thereby dissipating the pre - heat inside the motor, avoiding damage to the motor due to heat accumulation when starting again, and ensuring the working safety when the motor continuously starts and stops. It is suitable for power output use in mechanical equipment; When the device is working, it effectively ventilates the inner and outer sides of the stator, so that the heat generated by the coils inside the stator can be quickly dissipated outward. However, the existing device still has the following problems: When a traditional three - phase asynchronous motor operates under high load, a large amount of heat energy is generated. When the temperature around the three - phase asynchronous motor is relatively high, it is not convenient to efficiently dissipate heat from the three - phase asynchronous motor, which easily leads to the phenomenon of the circuit of the three - phase asynchronous motor being burned out and the three - phase asynchronous motor being damaged and scrapped. Therefore, a three - phase asynchronous motor with a fast cooling function is proposed. Summary of the Invention

At the same time, the heat in the protective frame 3 is transported to the cooling box 404 through the ventilation pipe 405, thereby reducing the temperature of the environment around the three-phase asynchronous motor body 1 and indirectly cooling the three-phase asynchronous motor body 1.

[0021] A filter screen plate 407 is fixedly connected to the inner wall of the ventilation opening, and a filter screen 4021 is fixedly connected to the left end face of the air outlet pipe 4020.

[0022] The ventilation pipe 405 is arranged as a C-shaped pipe, and a wind collecting hood 406 is fixedly connected to the lower right end face of the ventilation pipe 405.

[0023] On the right side of the ventilation pipe 405, there is a first spherical ball 408.

[0027] Embodiment 2: On the basis of Embodiment 1, a preferred embodiment of a three-phase asynchronous motor with a fast cooling function provided by the invention is as Figure 1 、 Figure 2 、Figure 4 - Figure 6 As shown in the figure: The mixing component 41 includes a rotary motor 411, a worm 412 and a support plate 413 above the protective frame 3. The left side surfaces of the rotary motor 411 and the support plate 413 are fixedly connected to the right side surface of the cooling box 404. The front end surface of the output rod of the rotary motor 411 is fixedly connected to the rear end surface of the worm 412. The front end surface of the worm 412 penetrates through the rear side surface of the support plate 413 and extends to the front side of the support plate 413. A first rotating rod 414 and a second rotating rod 415 are arranged below the worm 412. The surface of the worm 412 is rotationally connected to the inner wall of the support plate 413 through a bearing seat. The first rotating rod 414 and the second rotating rod 415 are symmetrically arranged. The surfaces of the first rotating rod 414 and the second rotating rod 415 are fixedly sleeved with worm wheels 416. The surface of the worm 412 meshes with the side surface of the worm wheel 416. The left end surfaces of the first rotating rod 414 and the second rotating rod 415 penetrate through the right side surface of the cooling box 404 and extend into the cooling box 404. The surfaces of the first rotating rod 414 and the second rotating rod 415 are rotationally connected to the inner wall of the cooling box 404 through bearing seats respectively. The surface of the first rotating rod 414 is fixedly connected with a second stirring rod 418, and the surface of the second rotating rod 415 is fixedly connected with a first stirring rod 417. Through the mixing component 41, the first stirring rod 417 and the second stirring rod 418 are driven to rotate by the first rotating rod 414 and the second rotating rod 415, which is convenient for mixing the ammonium chloride powder and barium hydroxide octahydrate powder in the cooling box 404, thereby increasing the cooling efficiency in the cooling box 404. A purification component (not shown in the figure) is connected to the right end surface of the air outlet pipe 4020 to avoid polluting the environment with the gas generated by the reaction.

[0028] Both the first stirring rod 417 and the second stirring rod 418 are located inside the cooling box 404, and the first stirring rod 417 and the second stirring rod 418 are arranged in a left-right staggered manner.

[0029] During use, when the three-phase asynchronous motor body 1 works, the output rod of the three-phase asynchronous motor body 1 drives the connected pulley 402 to rotate. Through belt transmission, the rotating shaft 401 rotates, and the rotating shaft 401 drives the blade 403 to rotate, so that the air flow speed in the protective frame 3 is accelerated, thereby cooling the three-phase asynchronous motor body 1 in the protective frame 3; Add barium hydroxide octahydrate powder into the adding pipe 4013, and then put ammonium chloride powder into the cooling box 404. The heat in the protective frame 3 enters the ventilation pipe 405 through the air collecting hood 406. The ventilation pipe 405 transfers the heat to the cooling box 404. The ventilation pipe 405 blows the first ball 408 to move, so that the first ball 408 drives the connecting plate 409 to move on the first slide bar 4010 and compress the first spring 4011. At the same time, the first ball 408 drives the push rod 4012 to move to the left. The push rod 4012 pushes the second ball 4014 to move to the right. The second ball 4014 pushes the second slide bar 4018 to move, and the second ball 4014 drives the stop block 4015 to move to the right. Thus, the barium hydroxide octahydrate powder in the adding pipe 4013 enters the cooling box 404 through the through hole. The barium hydroxide octahydrate powder contacts and reacts with the ammonium chloride powder in the cooling box 404 to reduce the temperature in the cooling box 404, reduce the stability of the heat entering the cooling box 404, and further reduce the temperature of the surrounding environment of the three-phase asynchronous motor body 1; Start the rotating motor 411. The output rod of the rotating motor 411 drives the connected worm 412 to rotate, so that the worm 412 drives the worm gear 416 to rotate. Further, the first rotating rod 414 and the second rotating rod 415 rotate and drive the first stirring rod 417 and the second stirring rod 418 to rotate. The first stirring rod 417 and the second stirring rod 418 stir and mix the barium hydroxide octahydrate powder and ammonium chloride powder in the cooling box 404, accelerate the reaction speed of the barium hydroxide octahydrate powder and ammonium chloride powder, and further improve the cooling efficiency.
