Description

Technical Field

[0001] The invention relates to the field of three-phase asynchronous motor technology, specifically a three-phase asynchronous motor with rapid cooling function. Background Technology

[0002] A three-phase asynchronous motor is an induction motor that is powered by a simultaneous connection of 380V three-phase alternating current (120-degree phase difference). Its rotor and stator rotating magnetic fields rotate in the same direction but at different speeds, exhibiting slip, hence the name three-phase asynchronous motor. A three-phase asynchronous motor mainly consists of two parts: the stator and the rotor. The stator is the stationary part, mainly including the stator core and stator windings; the rotor is the rotating part, including the shaft, rotor core, rotor support, and rotor windings. In addition, the motor also includes components such as the frame, end covers, bearings, and a fan.

[0003] According to a Chinese patent publication CN216530969U, a three-phase asynchronous motor with rapid cooling function includes a housing, a bracket, and a junction box. A mesh cover is bolted to one end of the housing, and a fan plate is welded to the inner side of the mesh cover. A stator is installed inside the housing, and a rotor is installed inside the stator. A main shaft is installed at one end of the rotor, and a rotating shaft is installed at the other end. Bearings are fitted on the outer sides of both the main shaft and the rotating shaft, and retaining covers are fitted on the outer sides of the bearings. This three-phase asynchronous motor with rapid cooling function can ventilate the inside and outside of the stator, quickly dissipating heat and reducing the motor's operating temperature, ensuring motor safety. The fan blades can continuously rotate, further dissipating preheating within the motor and preventing damage due to heat accumulation during restart. This ensures safe operation during continuous start-stop operation and is suitable for power output in mechanical equipment.

[0004] This device effectively ventilates the inside and outside of the stator when the motor is operating, thereby quickly dissipating the heat generated by the coils inside the stator. However, existing devices still have the following problems: traditional three-phase asynchronous motors generate a large amount of heat when operating under high loads. When the ambient temperature around the three-phase asynchronous motor is high, it is not easy to efficiently dissipate heat, which can easily lead to circuit burnout and damage to the motor. Therefore, a three-phase asynchronous motor with rapid cooling function is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a three-phase asynchronous motor with rapid cooling function to solve the problems mentioned in the background art.

The surface of the worm gear meshes with the side of the worm wheel. The left end of the first rotating rod and the left end of the second rotating rod extend through the right side of the cooling box to the inside of the cooling box. The surfaces of the first rotating rod and the second rotating rod are rotatably connected to the inner wall of the cooling box through bearing seats.

[0012] Preferably, a filter screen is fixedly connected to the inner wall of the vent, and a filter screen is fixedly connected to the left end face of the air outlet pipe.

[0013] Preferably, the ventilation duct is configured as a C-shaped duct, and a heat collection hood is fixedly connected to the lower right end face of the ventilation duct. The heat collection hood facilitates the entry of heat from the protective frame into the ventilation duct.

[0014] Preferably, a first sphere is provided on the right side of the ventilation pipe, and a connecting plate is fixedly connected to both the front and back of the first sphere. A first sliding rod is provided on the left side of the connecting plate, and the right end face of the first sliding rod slides through the left side of the connecting plate to the right side of the connecting plate.

The staggered arrangement of the first and second stirring rods facilitates the mixing of ammonium chloride powder and barium hydroxide octahydrate powder in the cooling box, thereby increasing the cooling of the gas entering the cooling box.

[0019] Compared with existing technologies, the beneficial effects of the invention are:

[0020] 1. The three-phase asynchronous motor with rapid cooling function uses a cooling component to increase the airflow speed in the protective frame by rotating the blades when the motor body is working. This cools the motor body in the protective frame. At the same time, the ventilation pipes transfer the heat from the protective frame to the cooling box, thereby reducing the temperature of the environment around the motor body and indirectly cooling the motor body.

[0021] 2. The three-phase asynchronous motor with rapid cooling function blows the first ball through the ventilation pipe, causing the push rod to push the second ball to move. This causes the stop block to move away from the through hole, making it easier for the barium hydroxide octahydrate powder in the addition tube to fall into the cooling box, thereby increasing the heat absorption time of the reaction and further improving the cooling effect on the gas entering the cooling box.

[0022] 3. The three-phase asynchronous motor with rapid cooling function, through the second slide bar, the second spring and the stop bar, facilitates the movement of the second ball to the left when the gas entering the cooling box weakens, thereby reducing the amount of barium hydroxide octahydrate powder entering the cooling box from the addition tube, thus avoiding the waste of barium hydroxide octahydrate powder raw material;

[0023] 4. The three-phase asynchronous motor with rapid cooling function, through the mixing component, uses the first rotating rod and the second rotating rod to drive the first stirring rod and the second stirring rod to rotate, which facilitates the mixing of ammonium chloride powder and barium hydroxide octahydrate powder in the cooling box, thereby increasing the cooling efficiency in the cooling box.

The right end face of the rotating shaft 401 is rotatably connected to the right side of the inner side of the protective frame 3 via a bearing seat. The left end face of the rotating shaft 401 is fixedly connected to the right side of the blades 403. A ventilation opening is provided through the right side of the protective frame 3. A ventilation pipe 405 is provided on the left side of the blades 403. A cooling box 404 is fixedly connected to the top surface of the protective frame 3. The upper right end face of the ventilation pipe 405 is fixedly inserted through the top surface of the inner side of the protective frame 3 and the left side of the cooling box 404, extending into the interior of the cooling box 404. A door 4022 is hinged to the front of the cooling box 404. An adding pipe 401 is provided above the cooling box 404. 3. The bottom end of the adding tube 4013 is fixedly inserted through the top surface of the cooling box 404 and extends into the interior of the cooling box 404. A cover plate 4023 is hinged to the top surface of the adding tube 4013. An air outlet pipe 4020 is provided on the right side of the adding tube 4013. The right end of the air outlet pipe 4020 is fixedly inserted through the right side of the interior of the cooling box 404 and extends into the right side of the cooling box 404. Through the cooling component 40, the blades 403 are driven to rotate when the three-phase asynchronous motor body 1 is working, thereby increasing the air flow speed in the protective frame 3, which in turn cools the three-phase asynchronous motor body 1 in the protective frame 3. At the same time, the heat in the protective frame 3 is transferred 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.

[0039] A filter screen 407 is fixedly connected to the inner wall of the vent, and a filter screen 4021 is fixedly connected to the left end face of the air outlet pipe 4020.

[0040] The ventilation duct 405 is a C-shaped duct, and a wind collection hood 406 is fixedly connected to the lower right end face of the ventilation duct 405.

[0041] A first sphere 408 is provided on the right side of the ventilation duct 405. Connecting plates 409 are fixedly connected to both the front and back of the first sphere 408. A first sliding rod 4010 is provided on the left side of the connecting plate 409. The right end face of the first sliding rod 4010 slides through the left side of the connecting plate 409 and extends to the right side of the connecting plate 409. The left and right end faces of the first sliding rod 4010 are fixedly connected to the left and right sides of the interior of the cooling box 404, respectively. A first spring 4011 is fixedly sleeved on the surface of the first sliding rod 4010. The left and right end faces of the first spring 4011 are respectively connected to the right side of the connecting plate 409 and the interior of the cooling box 404. The right side of the first sphere 408 is fixedly connected to a push rod 4012. The right end of the push rod 4012 slides through the left side of the addition tube 4013 and extends into the addition tube 4013. The first sphere 408 is blown by the ventilation tube 405, which causes the push rod 4012 to push the second sphere 4014 to move. Then the stop block 4015 moves away from the through hole, so that the barium hydroxide octahydrate powder in the addition tube 4013 can fall into the cooling box 404, thereby increasing the endothermic time of the reaction and further improving the cooling effect on the gas entering the cooling box 404.

[0042] A partition 4017 is fixedly connected to the inner side of the tube 4013. A through hole is opened on the top surface of the partition 4017.

The bottom surface of the stop block 4015 is slidably connected to the top surface of the partition 4017. The stop block 4015 is located above the through hole. The top surface of the stop block 4015 is fixedly connected to the bottom surface of the second ball 4014. The second ball 4014 is located to the right of the push rod 4012.

[0043] The right side of the second sphere 4014 is fixedly connected to the left end of the second slide rod 4018.

The left and right ends of the second spring 4019 are fixedly connected to the right side of the second sphere 4014 and the inside right side of the adding tube 4013, respectively. Through the second slide rod 4018, the second spring 4019 and the stop rod 4016, the second sphere 4014 can move to the left when the gas entering the cooling box 404 weakens, thereby reducing the amount of barium hydroxide octahydrate powder entering the cooling box 404 from the adding tube 4013, thus avoiding the waste of barium hydroxide octahydrate powder raw material.

[0044] A positioning rod 4016 is fixedly connected to the left side of the stop block 4015, and the left end face of the positioning rod 4016 contacts the inner left side of the adding tube 4013.

[0045] Example 2: Based on Example 1, a preferred embodiment of the three-phase asynchronous motor with rapid cooling function provided by the invention is as follows: Figure 1 , Figure 2 , Figure 4 - Figure 6 As shown: The mixing component 41 includes a rotary motor 411, a worm gear 412, and a support plate 413 above the protective frame 3. The left side of the rotary motor 411 and the left side of the support plate 413 are both fixedly connected to the right side of the cooling box 404. The front end of the output rod of the rotary motor 411 is fixedly connected to the rear end of the worm gear 412. The front end of the worm gear 412 extends through the rear side of the support plate 413 to the front side of the support plate 413. A first rotating rod 414 and a second rotating rod 415 are provided below the worm gear 412. The surface of the worm gear 412 is rotatably 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. A worm wheel 416 is fixedly sleeved on the surface of the first rotating rod 414 and the surface of the second rotating rod 415. The surface of the worm gear 412 meshes with the side of the worm wheel 416. The first rotating rod 414... The left end face and the left end face of the second rotating rod 415 both extend through the right side of the cooling box 404 into the interior of the cooling box 404. The surfaces of the first rotating rod 414 and the second rotating rod 415 are rotatably connected to the inner wall of the cooling box 404 through bearing seats. The surface of the first rotating rod 414 is fixedly connected to the second stirring rod 418, and the surface of the second rotating rod 415 is fixedly connected to the first stirring rod 417. Through the mixing assembly 41, the first rotating rod 414 and the second rotating rod 415 drive the first stirring rod 417 and the second stirring rod 418 to rotate, which facilitates the mixing of 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 assembly (not shown in the figure) is connected to the right end face of the gas outlet pipe 4020 to avoid the gas produced by the reaction from polluting the environment.

[0046] The first stirring rod 417 and the second stirring rod 418 are both located inside the cooling box 404, and the first stirring rod 417 and the second stirring rod 418 are arranged alternately from left to right.

[0047] When in use, when the three-phase asynchronous motor body 1 is working, the output rod of the three-phase asynchronous motor body 1 drives the connected pulley 402 to rotate, and the shaft 401 rotates through the belt drive. The shaft 401 drives the blade 403 to rotate, which increases the airflow speed in the protective frame 3, thereby cooling the three-phase asynchronous motor body 1 in the protective frame 3.

[0048] Barium hydroxide octahydrate powder is added to the adding tube 4013, and then ammonium chloride powder is placed into the cooling box 404. The heat in the protective frame 3 enters the ventilation pipe 405 through the air collector 406. The ventilation pipe 405 transfers the heat to the cooling box 404. The ventilation pipe 405 blows the first ball 408 to move, causing the first ball 408 to drive the connecting plate 409 to move on the first slide rod 4010 and squeeze the first spring 4011. At the same time, the first ball 408 drives the push rod 4012 to move to the left. 2. Push the second ball 4014 to move to the right. The second ball 4014 pushes the second slide bar 4018 to move. The second ball 4014 also drives the stop block 4015 to move to the right. This allows the barium hydroxide octahydrate powder in the adding tube 4013 to enter the cooling box 404 through the through hole. The barium hydroxide octahydrate powder reacts with the ammonium chloride powder in the cooling box 404 to reduce the temperature in the cooling box 404, thereby reducing the stability of the heat entering the cooling box 404 and thus reducing the temperature of the environment around the three-phase asynchronous motor body 1.

[0049] When the rotary motor 411 is turned on, the output rod of the rotary motor 411 drives the connected worm gear 412 to rotate, which in turn drives the worm wheel 416 to rotate. This causes the first rotating rod 414 and the second rotating rod 415 to rotate, which in turn drives 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, thereby accelerating the reaction rate of the barium hydroxide octahydrate powder and ammonium chloride powder and improving the cooling efficiency.
