Description

Technical Field

[0001] The invention belongs to the technical field of electric motors, in particular to an explosion-proof water-cooled ultra-high-efficiency three-phase permanent magnet synchronous motor. Background Art

[0002] The three-phase permanent magnet synchronous motor mainly uses the interaction between the rotating magnetic field generated by the stator winding and the permanent magnet magnetic field on the rotor to achieve the rotation of the motor. When three-phase alternating current is passed into the stator winding, a rotating magnetic field is generated. The speed of this magnetic field is related to the frequency of the power supply and the number of pole pairs of the motor. When the synchronous motor is running, its internal structure needs to be cooled by water cooling.

[0003] The explosion-proof water-cooled ultra-efficient three-phase permanent magnet synchronous motor uses water cooling to absorb the heat generated by the operation of the internal parts of the permanent magnet synchronous motor, and then uses the flow of water to absorb heat to transfer the absorbed heat to the outside of the synchronous motor for heat dissipation, thereby avoiding the high temperature generated by the internal temperature of the synchronous motor due to excessive temperature. It is easy to cause the relatively closed space inside the synchronous motor to explode due to factors such as high temperature and parts friction, thereby not only improving the efficiency of the synchronous motor operation, but also reducing the explosion of the synchronous motor due to high temperature; However, in life, when water cooling is used to dissipate heat inside a three-phase permanent magnet synchronous motor, the efficiency of heat dissipation is easily affected by the quality of the cooling water. When the cooling water carries more calcium and magnesium ions, scale will form on the inner wall of the water pipe. More scale will easily cause blockage of the inner wall of the pipe, reducing the heat transfer efficiency of the pipe, thereby affecting the cooling effect. Summary of the invention

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] Embodiment 1: The present application proposes an explosion-proof water-cooled ultra-high efficiency three-phase permanent magnet synchronous motor, as shown in the accompanying drawings of the specification. Figure 1-6As shown, it includes a body 1, one end of which is fixedly connected to a cooling pipe 11, and the upper end of the cooling pipe 11 is fixedly connected to a water inlet pipe 12 and a water outlet pipe 13, and one end of the water inlet pipe 12 and the water outlet pipe 13 is fixedly connected to a water cooling assembly: the water cooling assembly includes a first storage box 2 arranged outside the end of the water inlet pipe 12 away from the cooling pipe 11, and one end of the first storage box 2 is provided with a water inlet 21, the outer side of the end of the first storage box 2 close to the water inlet pipe 12 is fixedly connected to a first water pump 22, and the end of the first water pump 22 close to the first storage box 2 is fixedly connected to a first water pipe 23, and the first water pump 22 close to the first storage box 2 One end of the water inlet pipe 12 is fixedly connected to the water inlet pipe 12, and one end of the first water pipe 23 away from the first water pump 22 is inserted into the first storage box 2. When the three-phase permanent magnet synchronous motor is cooled, the cooling water is first injected into the first storage box 2 through the water inlet 21. The electromagnetic field generated by the operation of the electromagnetic processor 3 and the electromagnetic rod 31, when the water passes through the electromagnetic field, the physical and chemical properties of the calcium and magnesium ions in the water will change due to the effect of the magnetic field, thereby changing the crystal form of the calcium and magnesium ions in the water, making it less likely to form scale, and then through the first water pump 22 The cooling water is injected into the cooling pipe 11 by the first water pipe 23 to absorb the heat in the machine body 1. The cooling water after absorbing the heat flows back to the second storage box 4 through the water outlet pipe 13 for storage. Then the motor 7 is started to drive the rotating rod 72 and the first blade 73 to rotate and accelerate the flow rate of the cooling water. At the same time, the first gear 82 is driven to rotate through the transmission belt 8 through the operation of the motor 7. Then the second blade 94 and the third blade 96 are driven to rotate through the first gear 82 through the second gear 9, etc. to dissipate the heat of the cooling water. Finally, the second storage box 4 is pumped out by the second water pump 41. The cooling water in the pipe is drawn out and injected into the first storage box 2 for recycling, which effectively avoids pipe blockage caused by high calcium and magnesium content in the water. At the same time, the flow rate of cooling water is increased, and the impact force of cooling water in the pipe is increased to avoid impurities in some water adhering to the inner wall of the pipe due to insufficient cooling water flow rate, resulting in the adhesion of scale due to low flow rate, resulting in the increase of the inner wall of the pipe after the scale is attached, affecting the heat absorption efficiency. Increasing the flow rate of cooling water can accelerate the heat dissipation effect of cooling water, reduce the subsequent reduction in heat absorption due to poor heat dissipation effect of cooling water, and affect the water cooling effect.

By utilizing the electromagnetic field generated by the operation of the electromagnetic processor 3 and the electromagnetic rod 31, when water passes through the electromagnetic field, the physical and chemical properties of calcium and magnesium ions in the water will change due to the action of the magnetic field, thereby changing the crystal form of calcium and magnesium ions in the water, making it less likely to form scale, and at the same time, the air entering from the upper end of the first protective cover 5 is filtered through the first filter screen 51.

[0020] Furthermore, a second filter screen 6 is inserted into the inner side of one end of the second storage box 4, and a first bracket 61 is fixedly connected to the upper end of the second filter screen 6, and the upper end of the first bracket 61 is fixedly connected to the first protective cover 5, and a motor 7 is fixedly connected to the inner side of the lower end of the second protective cover 52, and a transmission rod 71 is fixedly connected to the output shaft of the motor 7, and the end of the transmission rod 71 away from the motor 7 passes through the second storage box 4, and a rotating rod 72 is fixedly connected to the end of the transmission rod 71 away from the motor 7, and the end of the rotating rod 72 away from the transmission rod 71 is rotatably connected in the second storage box 4, and a first fan blade 73 is fixedly connected to the outer side of the rotating rod 72, and the outer sides of the rotating rod 72 and the first fan blade 73 are inserted into the inner side of the second filter screen 6. Through the operation of the motor 7, the rotating rod 72 and the first fan blade 73 are driven to increase the water flow rate, which can enhance the impact force of the cooling water flowing in the pipeline, avoid the adhesion of scale due to the low flow rate, thereby preventing the adhesion of scale to the pipeline, resulting in the increase of the inner wall of the pipeline after the scale is attached, affecting the heat absorption efficiency.

[0021] Furthermore, a transmission belt 8 is fixedly connected to the outer side of one end of the transmission rod 71 close to the motor 7, and a positioning rod 81 is fixedly connected to the outer side of the upper end of the transmission belt 8, and the positioning rod 81 is rotatably connected to the second protective cover 52 at one end away from the transmission belt 8, and a first gear 82 is fixedly connected to the side of the transmission belt 8 away from the positioning rod 81, and a second gear 9 is meshed with the outer side of one end of the first gear 82, and the lower side of the second gear 9 is rotatably connected to the first protective cover 5, and a first toothed belt 91 is meshed with the outer side of the upper end of the second gear 9, and the first toothed belt 91 is away from the second gear A tooth column 92 is meshed on the inner side of one end of 9, a second bracket 93 is fixedly connected to the lower side of the tooth column 92, and a second fan blade 94 is fixedly connected to the upper end of the tooth column 92, a second toothed belt 95 is meshed on the outer side of the upper end of the tooth column 92, and a third fan blade 96 is meshed on the inner side of an end of the second toothed belt 95 away from the tooth column 92. Through the rotation of the second fan blade 94 and the third fan blade 96, the outside air passes through the first filter screen 51 and enters the second storage box 4, and then forms an airflow in the second storage box 4, and the accelerated flow of the airflow is used to improve the heat dissipation efficiency of the cooling water.

[0022] Specific working process: when the interior of the machine body 1 is water-cooled, the cooling water is first injected into the first storage box 2 through the water inlet 21, and then the electromagnetic processor 3 is controlled to operate by the power supply 32, and the calcium and magnesium contained in the cooling water are processed by the electromagnetic rod 31. After the processing, the first water pump 22 and the motor 7 are started, and the cooling water in the first storage box 2 is pumped out and injected into the water inlet pipe 12 by the first water pipe 23 through the operation of the first water pump 22. The cooling water absorbs the heat inside the machine body 1 in the process of passing through the cooling pipe 11 through the water inlet pipe 12 and flowing into the water outlet pipe 13. After the motor 7 is started, the output shaft drives the transmission rod 71, the rotating rod 72 and the first fan blade 73 to rotate, and the rotation of the first fan blade 73 is used to accelerate the discharge of the cooling water. The cooling water that absorbs the heat passes through the water outlet pipe 13.

After the transmission belt 8 operates with the assistance of the positioning rod 81, it synchronously drives the first gear 82 to rotate. After the first gear 82 rotates, it drives the second gear 9 to rotate through the engagement with the second gear 9.
