Description

Technical Field

[0001] The invention belongs to the technical field of motors, in particular to a self-heating motor. Background Art

[0002] A motor is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. Its main function is to convert electrical energy into mechanical energy. The motor is one of the key components in the power system. It is also an important basis for driving various mechanical equipment and realizing electromechanical energy conversion in modern industrial and agricultural production, transportation, national defense, commerce and household appliances.

[0003] The Chinese patent application number CN202011074669.7 discloses a self-heating motor, including a housing, an exhaust bottom cover is installed at the bottom of the housing, the driving gear is sleeved on the side of the exhaust bottom cover, the bevel gear is connected to the driving gear, the rotating connecting rod is respectively installed on the bevel gear and the inner side of the housing, the connecting track is sleeved on the outside of the two rotating connecting rods, the blast side fan is sleeved on the top of one of the rotating connecting rods, and the exhaust side fan is sleeved on the outer side of the exhaust bottom cover. The invention can drive the driving gear to rotate through the self-rotation of the exhaust bottom cover, and cooperate with the meshing between the bevel gear and the driving gear, and the connecting track is connected to the connection transmission between the two rotating connecting rods, so that the bottom blast side fan inside the housing can rotate, and at the same time, the exhaust side fan is driven to rotate on the other side of the exhaust bottom cover, thereby realizing the blast heat dissipation of the bottom and one side of the motor housing. However, during the use of the patent, when the temperature inside the motor is low, the motor drives the exhaust fan to rotate, which increases the motor load, increases the motor rotation resistance, and easily causes the motor to heat up.

[0004] When the ambient temperature is high, especially when it exceeds 35°C, the heat dissipation efficiency of the motor will be significantly reduced. This is because the motor needs to dissipate the internal heat to the environment through the cooling system for heat exchange. If the external ambient temperature is too high, it will hinder the dissipation of heat. When the internal temperature of the motor is low, the motor drives the exhaust fan to rotate, increasing the motor load and the motor rotation resistance, which can easily cause the motor to heat up.

[0005] To this end, the present invention provides a self-heating motor. Summary of the invention

[0012] Preferably, a groove is provided at one end of the rotor close to the cooling box, and an airbag is fixedly connected to the inner circumference of the groove.

[0013] Preferably, the cooling assembly includes a storage box fixedly connected to the bottom end of the cooling box, and both sides of the storage box are connected to the interior of the cooling box through a first through pipe and a second through pipe respectively. A refrigeration fin is fixedly connected to the bottom end of the storage box, and the end of the refrigeration fin close to the storage box is a cold end.

[0014] Preferably, the airbag is filled with a heat-expanding gas, and the airbag expands when heated, so that the expanded airbag wraps and fixes one end of the reciprocating screw.

[0015] Preferably, a baffle is slidably connected to the inside of the air outlet, and a heat dissipation net is arranged inside the air outlet, and the heat dissipation net is located above the baffle.

[0019] Preferably, a guide block is fixedly connected to the top end of the cleaning ring, a spiral groove is formed on the inner wall of the air inlet cylinder, and one end of the guide block extends to the inside of the spiral groove.

[0020] Preferably, one end of the cleaning ring close to the moving ring is connected to a knocking block through a second spring, the outer wall of the knocking block is fixedly connected to a push rod, and one end of the moving ring close to the cleaning ring is fixedly connected to a wave block for pushing the push rod.

When the motor works for a long time, the internal temperature of the motor gradually rises, and the airbag expands due to the heat. The expansion of the airbag fixes one end of the reciprocating screw, and the reciprocating screw drives the fan blades to rotate. The rotation of the fan blades draws the external airflow into the motor through the air inlet pipe, quickly reducing the internal temperature of the motor, avoiding the motor from being in a heating state for a long time, reducing the motor rotation resistance, improving the motor working efficiency, and ensuring the safe operation of the motor.

DETAILED DESCRIPTION

[0035] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0036] Embodiment 1

[0037] For existing motors, if the external environment temperature is too high, it will hinder the heat dissipation, thereby causing the internal temperature of the motor to rise, affecting the service life of the motor.

[0038] like Figure 1 , Figure 2 As shown, a self-heating motor comprises a motor housing 1, a rotor 5 and fan blades 2. An air outlet 3 is provided at the top of the motor housing 1, and the motor housing 1 also comprises a cooling box 7. The outer wall of the cooling box 7 is fixedly connected to the motor housing 1. The interior of the cooling box 7 is filled with coolant. An air inlet tube 12 is fixedly connected to the interior of the cooling box 7. Both ends of the air inlet tube 12 extend out of the outer wall of the cooling box 7. A through hole for the fan blades 2 to rotate is provided inside the motor housing 1. The fan blades 2 are located inside the through hole. The position of the through hole can be blocked by the cooling box 7. A baffle 6 is slidably connected to the interior of the air outlet 3. The baffle 6 is provided with an air outlet identical to the air outlet 3. A heat dissipation net 4 is provided inside the air outlet 3. The heat dissipation net 4 is located above the baffle 6. The air outlet on the baffle 6 corresponds to the position of the air outlet 3. The heat dissipation net 4 can effectively prevent external debris from entering the interior of the motor housing 1, thereby effectively providing protection.

[0039] When the fan blades 2 rotate to suck in the external air flow, it can only enter the interior of the motor housing 1 through the air inlet pipe 12 arranged on the cooling box 7. Since the cooling box 7 is provided with coolant inside, and the air inlet pipe 12 is always located inside the cooling box 7, the coolant is wrapped in the outside of the air inlet pipe 12 in real time to keep the cooling of the air inlet pipe 12. Therefore, when the high-temperature air flow from the outside passes through the inside of the air inlet pipe 12, the hot air flow is cooled by the colder air inlet pipe 12, thereby reducing the temperature of the external air, which can improve the heat dissipation effect of the electrical components inside the motor housing 1. The gas entering the motor housing 1 through the air inlet pipe 12 can only be discharged through the air outlet 3 opened at the top. The heat dissipation net 4 can effectively prevent external debris from entering the interior of the motor housing 1, effectively play a protective effect, thereby controlling the temperature of long-term outdoor work and further improving the service life.

[0040] like Figure 3 As shown, the cooling component is arranged on the cooling box 7, and is used for cooling the incoming coolant. The top water plate 11 is slidably connected to the inside of the cooling box 7, and is used for sending the water in the cooling box 7 into the cooling component for cooling. The outer wall of the top water plate 11 fits with the inside of the cooling box 7. When the top water plate 11 slides inside the cooling box 7, the coolant inside the cooling box 7 can be pushed.

[0041] like Figures 1 to 4 As shown, the cooling assembly includes a storage box 14 fixedly connected to the bottom end of the cooling box 7, and both sides of the storage box 14 are connected to the interior of the cooling box 7 through a first through pipe 13 and a second through pipe 15 respectively. The first through pipe 13 and the second through pipe 15 are symmetrically arranged inside the cooling box 7, the first through pipe 13 is located on the left side of the cooling box 7, and the second through pipe 15 is located on the right side. A refrigeration plate 16 is fixedly connected to the bottom end of the storage box 14, and the end of the refrigeration plate 16 close to the storage box 14 is a cold end.

[0042] After the cooling box 7 is used for a long time, the coolant inside it will gradually heat up under the influence of the external temperature and the temperature of the air inlet tube 12, and finally it will affect the treatment of the incoming hot air. When the top water plate 11 is controlled by the transmission component to slide toward the right inside the cooling box 7, the coolant inside the cooling box 7 can be pushed toward the right. At this time, the coolant on the right side of the top water plate 11 is squeezed and can enter the inside of the second through pipe 15 and enter the inside of the storage box 14. At this time, the coolant will continue to be pushed, so the coolant entering the storage box 14 will enter the cooling box again from the first through pipe 13. Inside the temperature box 7, when the top water plate 11 slides toward the left side inside the cooling box 7, the coolant on the left side of the cooling box 7 can be squeezed into the first through pipe 13 and enter the interior of the cooling box 7 from the second through pipe 15. The refrigeration plate 16 can cool the bottom end of the storage box 14. Therefore, when the coolant enters the storage box 14, it will contact the cooled storage box 14, thereby realizing the cooling of the coolant. Cycling the above operations can effectively ensure that the coolant is at a lower temperature. At the same time, the top water plate 11 pushes the coolant to move inside the cooling box 7, bringing hot air into the air duct 12, so that the air inside the air inlet duct 12 is cooled.

[0043] By controlling the top water plate 11 to slide inside the cooling box 7, the coolant inside the cooling box 7 can be pushed into the storage box 14 and cooled by the refrigeration plate 16. The coolant is then transported back to the cooling box 7 to achieve water circulation cooling, which can improve the heat dissipation effect of the motor housing 1, thereby controlling the temperature of the motor working outdoors and further improving its service life.

[0044] Embodiment 2

[0045] On the basis of the above-mentioned embodiment, when the internal temperature of the motor is low, the motor drives the exhaust fan to rotate, which increases the motor load and the motor rotation resistance, and easily causes the motor to heat up.

[0046] like Figures 1 to 5As shown, the top water plate 11 is slidably connected to the inside of the cooling box 7, and the top water plate 11 slides with the outer wall of each air inlet tube 12, and is used to send the water in the cooling box 7 into the cooling component for cooling. The transmission component is arranged in the cooling box 7, and is used to control the sliding of the top water plate 11 in the cooling box 7. A groove 8 is opened at one end of the rotor 5 close to the cooling box 7, and an air bag 9 is fixedly connected to the inner circumference of the groove 8. The inside of the air bag 9 is filled with heat-expanding gas, which expands when heated and contracts when cooled. The air bag 9 expands when heated, so that the air bag 9 expands and fixes one end of the reciprocating screw 10, and the air bag 9 contracts when cooled. The contracted air bag 9 cannot drive the reciprocating screw 10 to rotate. The transmission component includes a reciprocating screw 10, one end of the reciprocating screw 10 is rotatably connected to the air bag 9, the outer wall of the reciprocating screw 10 is rotatably connected to the cooling box 7, the other end of the reciprocating screw 10 passes through the cooling box 7 and is fixedly connected to the fan blade 2, and the top water plate 11 is connected to the reciprocating screw 10 by a thread.

[0047] When the motor initially rotates, the rotor 5 rotates and works. At this time, the internal temperature of the motor is low, the airbag 9 is not affected, the airbag 9 is not connected to the reciprocating screw 10, and the fan blade 2 does not rotate, which reduces the motor load, reduces the motor rotation resistance, and improves the motor use efficiency;

[0048] When the motor works for a long time, the internal temperature of the motor gradually rises, and the motor generates more heat, which makes it difficult for the motor to dissipate heat. The airbag 9 is filled with heat-expanding gas. The airbag 9 expands due to the heat, and the expanded airbag 9 wraps and fixes one end of the reciprocating screw 10, so that the rotor 5 drives the reciprocating screw 10 to rotate through the airbag 9, and the reciprocating screw 10 drives the fan blades 2 to rotate. The rotation of the fan blades 2 draws the external airflow into the motor through the air inlet tube 12. The internal coolant of the cooling box 7 cools the airflow inside the air inlet tube 12, quickly reduces the internal temperature of the motor, avoids the motor from being in a heating state for a long time, improves the working efficiency of the motor, and ensures the safe operation of the motor. After the internal temperature of the motor is cooled, the airbag 9 returns to its original state, the airbag 9 is rotatably connected to the reciprocating screw 10, and the fan blades 2 do not rotate, thereby reducing the motor load, reducing the motor rotation resistance, and improving the motor utilization efficiency.

[0049] like Figures 6 to 9 As shown, a moving ring 21 is slidably connected to the inside of the air inlet cylinder 12. The moving ring 21 is made of ferromagnetic material. A filter is arranged inside the moving ring 21. A guide groove 20 is provided on the outer wall of the air inlet cylinder 12. A magnet 19 is fixedly connected to the top water plate 11. One end of the magnet 19 extends to the inside of the guide groove 20. When the magnet 19 moves, the moving ring 21 is driven to move synchronously through magnetic attraction. The magnet 19 can move in the guide groove 20. The magnet 19 limits the rotation of the top water plate 11 inside the cooling box 7, so that the top water plate 11 can move left and right inside the cooling box 7.

[0050] When the top water plate 11 slides inside the cooling box 7, it will simultaneously drive the magnet 19 to slide inside the guide groove 20. The magnet 19 and the moving ring 21 are magnetically attracted to each other, so that the top water plate 11 drives the moving ring 21 to slide synchronously through the magnet 19 when moving. When the moving ring 21 slides, it can also drive the filter to slide, so that the filter can be slid out of the opening of the air inlet tube 12, so as to clean the dust and impurities on the surface of the filter.

[0051] like Figures 6 to 9 As shown, the side wall of the movable ring 21 is rotatably connected to a cleaning ring 22, and the cleaning ring 22 is located on the right side of the air inlet cylinder 12. A cleaning strip 25 is fixedly connected to the inside of the cleaning ring 22, and one end of the cleaning strip 25 is fitted with the filter screen. The top of the cleaning ring 22 is fixedly connected to a guide block 23, and a spiral groove 24 is provided on the inner wall of the air inlet cylinder 12. One end of the guide block 23 extends to the inside of the spiral groove 24. The end of the cleaning ring 22 close to the movable ring 21 is connected to a knocking block 17 through a second spring, and the outer wall of the knocking block 17 is fixedly connected to a push rod 18. The end of the movable ring 21 close to the cleaning ring 22 is fixedly connected to a wave block 26 for pushing the push rod 18. A plurality of wave blocks 26 are provided, which are arranged in a ring shape at one end of the movable ring 21 close to the cleaning ring 22.

[0052] When the moving ring 21 slides along the top water plate 11 under the cooperation of the magnetic attraction between the magnet 19 and the moving ring 21, the guide block 23 arranged on the outer wall of the cleaning ring 22 will be driven to slide inside the spiral groove 24. At this time, the cleaning ring 22 will rotate on one side of the moving ring 21. When the cleaning ring 22 rotates, the cleaning strip 25 can rotate on the surface of the filter screen, effectively removing impurities on the surface of the filter screen, thereby ensuring the filtering effect of the filter screen. At the same time, when the cleaning ring 22 rotates, the pressing rod 18 will slide along the wave block 26. Through the transmission of the pressing rod 18, the knocking block 17 will be driven to shrink inside the cleaning ring 22. At the same time, in conjunction with the second spring, reciprocating sliding can be achieved to knock on the side wall of the moving ring 21. The vibration generated by the knocking can further improve the cleaning effect of the filter screen.

[0053] When the movable ring 21 is moved by the top water plate 11, the cleaning ring 22 will rotate with the cooperation of the spiral groove 24 and the guide block 23. When the cleaning ring 22 rotates, the cleaning strip 25 can rotate on the surface of the filter screen, effectively removing impurities on the surface of the filter screen. The pressure rod 18 is set to slide along the wave block 26, which will drive the knocking block 17 to shrink inside the cleaning ring 22. At the same time, with the cooperation of the second spring, reciprocating sliding can be achieved to knock on the side wall of the movable ring 21. The vibration generated by the knocking can further improve the cleaning effect of the filter screen.

[0054] Through the cooperation between the airbag 9 and the reciprocating screw 10, when the internal temperature of the motor is low, the airbag 9 is not connected to the reciprocating screw 10, and the fan blade 2 does not rotate, thereby reducing the motor load, reducing the motor rotation resistance, and improving the motor use efficiency. When the motor works for a long time, the internal temperature of the motor gradually rises, and the airbag 9 expands due to the heat, so that the airbag 9 expands to fix one end of the reciprocating screw 10, and the reciprocating screw 10 drives the fan blade 2 to rotate. The rotation of the fan blade 2 draws the external airflow into the motor through the air inlet tube 12, quickly reducing the internal temperature of the motor, avoiding the motor being in a heating state for a long time, reducing the motor rotation resistance, improving the motor working efficiency, and ensuring the safe operation of the motor.
