Description

Technical Field

[0001] The present invention relates to the technical field of electric motors, and in particular to a three-phase asynchronous motor with a function of supplementing a cooling medium. Background Art

[0002] The three-phase asynchronous motor is a common AC motor. A three-phase symmetrical AC current is passed through its stator winding to generate a rotating magnetic field. The rotor conductor induces current under the action of the magnetic field and interacts with the rotating magnetic field to generate electromagnetic torque, thereby realizing the conversion of electrical energy into mechanical energy. It has the advantages of simple structure, reliable operation, easy maintenance and low cost. It is widely used in many fields such as industry, agriculture and transportation, providing power support for various mechanical equipment. It is one of the indispensable power equipment in modern production and life.

[0003] In order to prevent overheating, existing three-phase asynchronous motors are usually equipped with liquid cooling and air cooling systems. However, the cooling medium in the liquid cooling system will be consumed after long-term use and needs to be replenished manually, which is time-consuming and labor-intensive. If it is not replenished, the cooling effect of the liquid cooling system will be affected. In addition, in order to avoid affecting the rotation of the output shaft, the air cooling system on the three-phase asynchronous motor is usually only set on the side of the motor away from the output shaft. However, this design will make the cooling effect of the air cooling system on the side of the motor close to the output shaft poor, resulting in poor overall heat dissipation effect of the three-phase asynchronous motor.

[0004] Based on the above situation, the present invention proposes a three-phase asynchronous motor with good heat dissipation effect and the function of supplementing cooling medium. Summary of the Invention

DETAILED DESCRIPTION

[0036] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection and application of the present invention.

[0037] Example 1 A three-phase asynchronous motor with a function of supplementing cooling medium, such as Figures 1-8 As shown, it includes an organism 1, an output shaft 11, a protective shell 12, a rotary fan 1201, a connecting pipe 13, a mounting plate 14, a hollow heat conducting plate 15, a liquid transfer box 16, a contraction block 1601, a liquid storage box 17, an air cylinder 18, a movable frame 19, a telescopic frame 110, an eccentric block 111, an extrusion block 112 and a one-way valve 113. The middle part of the body 1 is rotatably connected to the output shaft 11, the right side of the body 1 is fixedly connected to the protective shell 12, the inside of the protective shell 12 is rotatably connected to the rotary fan 1201, the output shaft 11 is fixedly connected to the rotary fan 1201, the lower left part of the body 1 is fixedly connected to the mounting plate 14, the inside of the mounting plate 14 is fixedly connected to the liquid transfer box 16, the front side of the liquid transfer box 16 is fixedly connected to the contraction block 1601, the outside of the body 1 is fixedly connected to the hollow heat conducting plate 15, ... The front and rear sides of the hot plate 15 and the transfer tank 16 are fixedly connected and communicated with an axially distributed connecting pipe 13, the front and rear sides of the mounting plate frame 14 are fixedly connected with a liquid storage tank 17, the liquid storage tank 17 and the transfer tank 16 are fixedly connected with a pipe with a check valve, the lower right side of the body 1 is fixedly connected with an air cylinder 18, the air cylinder 18 and the transfer tank 16 are fixedly connected with an air pipe, the upper right side of the body 1 is fixedly connected with a telescopic frame 110, the telescopic end of the telescopic frame 110 is fixedly connected with a movable frame 19, the movable frame 19 is fixedly connected to the piston rod of the air cylinder 18, the right side of the output shaft 11 is fixedly connected with an eccentric block 111, the eccentric block 111 is squeezed and fitted with the movable frame 19, the right rear side of the transfer tank 16 is slidably connected with an extrusion block 112, and the left and right sides of the transfer tank 16 are fixedly connected.

[0038] like Figure 6 and Figure 8 As shown, a check valve is fixedly connected to the middle of the connecting pipe 13 axially distributed on the rear side.

[0039] When the worker starts the three-phase asynchronous motor, the output shaft 11 will rotate continuously and drive the rotary fan 1201 to rotate. The rotation of the rotary fan 1201 can make the air flow flow from left to right and take away the heat of the body 1 and other components. However, since the rotary fan 1201 is located on the right side of the body 1, the air flow guided by the rotary fan 1201 has a poor cooling effect on the left side of the body 1. In addition, the rotation of the output shaft 11 will also drive the eccentric block 111 to rotate together, and the rotation of the eccentric block 111 will contact and squeeze the movable frame 19, thereby causing the movable frame 19 and the piston rod of the air cylinder 18 to move up and down, and the telescopic frame 110 will also shorten and lengthen back and forth. When the air cylinder 18 When the piston rod of the gas cylinder 18 moves downward, the piston rod of the gas cylinder 18 will inject the gas in the cylinder into the right part of the rear side of the transfer tank 16 through the air pipe, thereby squeezing the squeezing block 112 to move to the left. Since there are two one-way valves 113 in the middle of the transfer tank 16, and a check valve is also installed on the connecting pipe 13 distributed axially at the rear side, the squeezing block 112 moves to the left, causing part of the cooling medium in the rear chamber of the transfer tank 16 to pass through the connecting pipe 13 and the hollow heat conducting plate 15 and flow into the front chamber. During this period, the cooling medium flows in the hollow heat conducting plate 15 to perform liquid cooling on components such as the body 1. When the cooling medium enters the front chamber, it squeezes the contraction block 16 01, the shrinking block 1601 is deformed and shrunk immediately. When the piston rod of the air cylinder 18 moves upward and resets, the piston rod of the air cylinder 18 will draw the gas on the right rear side of the transfer box 16 back to the cylinder body through the air pipe, and the squeezing block 112 is immediately moved to the right and reset. The rear chamber of the transfer box 16 also immediately draws the cooling medium from the front chamber through the one-way valve 113 to replenish it. The shrinking block 1601 is immediately deformed and restored to its original shape, so that the cooling medium can circulate with the help of the power of the motor itself and cool down the components such as the body 1 without the need for an additional power source to drive the cooling medium. When the cooling medium in the hollow heat conducting plate 15 is When the cooling medium is lost and small cavities are generated, the small cavities will flow into the transfer tank 16 along with the cooling medium. Once there are cavities inside the transfer tank 16, the cooling medium in the liquid storage tank 17 will be drawn through the pipeline for replenishment. In this way, the cooling medium in the hollow heat conduction plate 15 and other components can be automatically replenished when loss occurs, thereby ensuring the cooling effect of the liquid cooling system. A check valve is also installed in the pipeline between the transfer tank 16 and the liquid storage tank 17 to prevent the cooling medium from flowing back. When the worker turns off the three-phase asynchronous motor, the output shaft 11 stops rotating, and components such as the movable frame 19 and the extrusion block 112 also stop moving.

[0040] Example 2 On the basis of Example 1, Figure 9 and Figure 10As shown, it also includes an air guide mechanism, which is arranged on the body 1. The air guide mechanism includes a first air guide pipe 2, a cooling twist block 21, a second air guide pipe 22, a blowing plate 23 and an air collecting plate 24. The blowing plate 23 is fixed to the left side of the body 1, and the air collecting plate 24 is fixed to the right side of the protective shell 12. The cooling twist block 21 is fixed to the front and rear sides of the lower part of the body 1. The first air guide pipe 2 is fixedly connected and communicated between the air blowing plate 23 and the cooling twist block 21. The second air guide pipe 22 is fixedly connected and communicated between the air collecting plate 24 and the cooling twist block 21.

[0041] like Figure 10 As shown, the cooling torsion block 21 is wavy in shape.

[0042] like Figure 10 As shown, evenly distributed air inlet holes are opened on the left side of the air collecting plate 24.

[0043] When the rotary fan 1201 rotates and causes the air flow to flow from left to right, part of the air flow will enter the cooling twist block 21 through the air collecting plate 24 and the second air guide tube 22. Since the cooling twist block 21 is wavy and has a large contact area with the outside air, the cooling twist block 21 can better cool the air flow with the help of the outside air. The cooled air flow will enter the blowing plate 23 through the first air guide tube 2 and be ejected outward, thereby cooling the left side of the machine body 1 and the hollow heat conduction plate 15. In this way, part of the gas blown out by the rotary fan 1201 can be guided to the left side and effectively cool the left side of the machine body 1 and the hollow heat conduction plate 15, thereby improving the cooling effect of the air cooling system.

[0044] like Figure 11 and Figure 12 As shown, a cooling mechanism is also included, which is arranged on the body 1. The cooling mechanism includes an air flow box 3 and an air duct 31. The two air flow boxes 3 are respectively fixed to the front and rear sides of the lower part of the body 1. The air flow box 3 is fixed to the protective shell 12 and is connected to the air duct 31.

[0045] When the rotary fan 1201 rotates and causes the air flow to flow from left to right, the rotary fan 1201 can also guide the external air flow to flow from left to right and pass through the air flow box 3 and the air duct 31, so that the gas in the cooling block 21 can be effectively cooled by the cold air flowing from the outside, thereby improving the cooling effect of components such as the blowing plate 23 on the left side of the body 1 and the hollow heat conduction plate 15.

[0046] like Figure 2 and Figure 13 As shown, a heat dissipation mechanism is also included, which is arranged on the output shaft 11. The heat dissipation mechanism includes blades 4, a mounting block 41 and a spray rack 42. The mounting block 41 is fixed to the left side of the output shaft 11. The outside of the mounting block 41 is fixed with blades 4 distributed equidistantly around the circumference. The spray rack 42 is fixed to the upper left side of the body 1, and the spray rack 42 is fixed to and connected to the mounting plate frame 14.

[0047] When the output shaft 11 rotates continuously, the output shaft 11 also drives the mounting block 41 and the circumferentially evenly distributed blades 4 to rotate together, and the circumferentially evenly distributed blades 4 rotate continuously to guide the external airflow to flow from left to right and pass through the spray rack 42 and the mounting plate frame 14. The external airflow ejected from the spray rack 42 can cool the terminal box on the upper left side of the body 1, and the external airflow passing through the mounting plate frame 14 can cool the cooling medium in the liquid storage tank 17. In this way, the power of the motor itself can be used to cool the terminal box on the upper left side of the body 1 and the cooling medium in the liquid storage tank 17, thereby improving the cooling effect of the air cooling system and the liquid cooling system.

[0048] like Figure 14 and Figure 15 As shown, a circulation mechanism is also included, which is arranged in the liquid transfer box 16. The circulation mechanism includes an electromagnet 5, a telescopic rod 51, a copper spring piece 52 and a stop block 53. The two telescopic rods 51 are respectively fixed to the front and rear sides of the interior of the liquid transfer box 16. The electromagnet 5 is fixed between the telescopic ends of the front and rear telescopic rods 51. The electromagnet 5 is magnetically engaged with the bottom of the liquid transfer box 16. The copper spring piece 52 is fixed to the lower rear part of the liquid transfer box 16. The electromagnet 5 is squeezed and engaged with the copper spring piece 52. The stop block 53 is fixed to the bottom of the rear inner wall of the liquid transfer box 16. The stop block 53 is in contact with the copper spring piece 52.

[0049] like Figure 14 and Figure 15 As shown, the copper shrapnel 52 is provided with leakage holes at both the front and rear parts on the left side.

[0050] When the worker starts the three-phase asynchronous motor, the electromagnet 5 is also energized and started. At this time, the electromagnet 5 is attracted by the rear bottom of the transfer tank 16 under the action of its own magnetism. Therefore, the electromagnet 5 moves downward under its own gravity and magnetic force and approaches the rear bottom of the transfer tank 16. The telescopic rod 51 is then stretched. During this period, the electromagnet 5 contacts and squeezes the copper spring 52, causing the copper spring 52 to deform and sag downward. At this time, the cooling medium at the bottom of the copper spring 52 will gradually enter the upper part of the rear chamber of the transfer tank 16 through the two leakage holes. When the worker turns off the three-phase asynchronous motor, the output shaft 11, the movable frame 19 and the extrusion block 112 stop working, and the electromagnet 5 is also de-energized and loses its magnetism. At this time, the copper spring 52 will be deformed under the action of its own elasticity. The electromagnet 5 is squeezed downward to restore to its original shape and moves upward to reset, and the telescopic rod 51 is restored to its original shape immediately. Moreover, due to the small diameter of the two leakage holes, the cooling medium in the upper part of the rear chamber of the transfer tank 16 does not have time to return to the bottom of the copper shrapnel 52 through the leakage holes during the rapid reset of the copper shrapnel 52. Therefore, the restoration of the copper shrapnel 52 will not only cause the cooling medium in the upper part of the rear chamber of the transfer tank 16 to flow into the front chamber through the connecting pipe 13 and the hollow heat conducting plate 15, but will also extract part of the cooling medium from the front chamber through the one-way valve 113 to replenish the bottom of the copper shrapnel 52. In this way, the cooling medium can continue to circulate to a certain extent after the motor stops working, thereby improving the cooling effect of the liquid cooling system. The support block 53 can resist the copper shrapnel 52 and assist it in restoring to its original shape.

Their purpose is to enable those skilled in the art to understand the contents of the present invention and implement them accordingly. They are not intended to limit the scope of protection of the present invention.
