As one of the key equipment, the safety and reliability of explosion-proof motors are directly related to production safety and personnel safety. However, permanent magnet motors in the prior art have the following defects:

[0003] In the prior art, the internal air circulation of the permanent magnet motor is poor, which will cause the heat inside the motor to be unable to be dissipated in time, thereby increasing the temperature of the motor. Long-term high-temperature operation will accelerate the aging of the insulation material inside the motor, reduce the insulation performance of the motor, and increase the risk of leakage and short circuit;

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] The present invention provides a large torque explosion-proof permanent magnet motor with cooling and regulating function. The second wind control unit assembly and the first wind control unit assembly are symmetrically arranged and staggered to achieve coordinated work to achieve alternating suction and discharge of airflow. When the driving device in the first wind control unit assembly is started (extended action), the driving device will push the arc push plate to move outward. When the arc push plate moves outward, the arc push plate inhales gas into the inside through the opening on the shell, and as the arc push plate moves outward to its extreme position, the arc push plate will further push the active gas collecting cylinder to expand outward, thereby increasing the suction space and achieving the maximum suction volume. At the same time, this action will enable the slider to slide in the moving groove, and compress the reset spring when it reaches the convex bending part. At the same time, the second wind control unit assembly is in the reset jet stage, and its active gas collecting cylinder moves to the leftmost position to release gas and complete the reset. During this process, the slider also synchronously moves back to the leftmost end of the moving slot, and the reset spring stretches accordingly to restore its original state. When the driving device of the first wind control unit assembly is retracted and shortened, the sliding block moves along the top of the slide slot, guiding the arc-shaped push plate to retract to the left, completing the reset after suction. Through this alternating operation mode and by alternating the intake and exhaust of gas, the system can ensure smooth circulation of the airflow inside the motor cavity, which can not only avoid dead corners and accumulation of airflow, but also effectively reduce motor overheating and performance degradation caused by poor airflow, and through the alternating operation mode, the two wind control unit assemblies can cooperate with each other to achieve continuous circulation of airflow. This design reduces the impact of a single component failure on the entire system and improves the reliability and stability of the system.

[0021] The present invention provides a large torque explosion-proof permanent magnet motor with cooling and regulating function. By providing an integrated exhaust and collecting device, when the gas enters the wind accumulation cavity and is filled, the second wind control unit assembly and the first wind control unit assembly arranged on the outside of the outer annular cylinder start to perform reciprocating and staggered air suction operations. The inhaled gas then enters the wind accumulation cavity again through the air outlet. After that, these gases will enter through a specific annular member and be discharged when reaching the exhaust valve. After the gas is released from the exhaust valve, it will flow between the arc-shaped wind shields arranged in the array. In this process, the wind shield will block the direct advancement of the gas, forcing the gas to be diverted through the gap reserved between the wind shield and the annular cover. The end of this path is the trumpet-shaped exhaust port of the annular cover, which is directly opposite to the space between the outer shell and the inner shell. In the process of gas being discharged through these structures, its flow will accelerate and produce a blowing effect on the butterfly-shaped heat sink, thereby achieving an effective heat dissipation effect. In this way, the entire device not only completes the collection and discharge of gas, but also adds a heat dissipation function. By blowing the butterfly-shaped heat sink directly by the gas, the heat dissipation efficiency can be significantly improved. The butterfly heat sink design usually increases the heat dissipation area, while the directional airflow can more effectively remove heat, reduce the operating temperature of the equipment and extend its service life.

[0022] The invention discloses a large torque explosion-proof permanent magnet motor with cooling and regulating function, which is provided with an active heat dissipation component, and the active heat dissipation component undertakes the important task of discharging the treated gas to the outside. The key to this process lies in the coordinated work of the secondary heat sink and the primary heat sink. The secondary heat sink adopts an annular sparse blade design, which quickly extracts and initially guides the gas flow when starting, and effectively adsorbs the heat dissipation gas by using the large suction force generated by it, thereby avoiding the initial stagnation of the airflow. Next, the primary heat sink intervenes with its design feature of annular dense blades, which more densely adsorbs the airflow pre-treated by the secondary heat sink during the rotation process, thereby further enhancing the control and exhaust efficiency of the airflow in the later stage. The primary heat sink not only strengthens the concentration of the gas during the adsorption process, but also significantly improves the flow speed and discharge pressure, ensuring that the heat dissipation gas can be discharged from the system more thoroughly and efficiently, effectively preventing the backflow or unnecessary stagnation of the airflow, and optimizing the flow path of the heat dissipation gas through the rapid extraction of the secondary heat sink and the intensive adsorption of the primary heat sink, so that the heat can be taken away faster, thereby ensuring the heat dissipation efficiency of the equipment. This design allows the equipment to maintain a low temperature even when running at high load, extending the service life of the equipment. The combined design of annular sparse blades and annular dense blades makes it difficult for the gas to generate eddy currents or stagnation during the flow process, while increasing the discharge pressure and effectively preventing the gas from flowing back. This ensures the continuity and stability of the heat dissipation process. BRIEF DESCRIPTION OF THE DRAWINGS

The movable gas collecting cylinder 35 is a semicircular cylindrical structure. The movable gas collecting cylinder 35 reciprocates along the inner wall path in the inner cavity 12. An arc-shaped push plate 42 is slidably provided inside the movable gas collecting cylinder 35. A sliding box 36 is provided on the top of the movable gas collecting cylinder 35.

The other end of the return spring 39 is connected to a fixed block 40. The fixed block 40 is fixed to the inner wall of the inner cavity 12. A sliding groove 43 is provided on the inner side surface of the arc-shaped push plate 42. A sliding block 44 is slidably provided in the sliding groove 43. A driving device 61 is connected to the outer side of the sliding block 44.

[0046] In this embodiment, the second wind control unit assembly 50 and the first wind control unit assembly 51 are arranged symmetrically and run in an interlaced manner, so as to work in coordination to achieve alternating inhalation and discharge of airflow. When the driving device 61 in the first wind control unit assembly 51 is started (extending action), the driving device 61 will push the arc-shaped push plate 42 to move outward. When the arc-shaped push plate 42 moves outward, the arc-shaped push plate 42 inhales gas into the interior through the opening on the shell, and as the arc-shaped push plate 42 moves outward to its extreme position, the arc-shaped push plate 42 will further push the movable gas collecting cylinder 35 to expand outward, thereby increasing the air suction space and achieving the maximum air suction volume.

[0056] Specific use of the present invention:

[0057] When using the present invention, first align the motor base of the present invention with the bolt holes on the base platform and ensure that the base is placed stably on the platform surface. Subsequently, high-strength bolts are passed through the mounting holes of the motor base in sequence, and the bolts are gradually tightened according to the specified torque standard using a torque wrench to ensure a tight connection between the motor and the base platform to avoid any looseness or displacement. To further enhance stability, anti-loosening washers or thread glue can be used before the bolts are installed to improve the vibration resistance, thereby extending the service life of the equipment.

[0058] Subsequently, when the motor is started, the rotor 29 arranged inside the inner cavity 12 will rotate. When the rotor 29 rotates inside the stator 28, the stator 28 will generate heat by friction, and the heat will accumulate inside the rotating inner cavity 26. After the heat is generated inside the rotating inner cavity 26, it will be dissipated to the outside through the butterfly heat sink 24 provided on the surface of the inner shell 25. When the butterfly heat sink 24 is dissipating heat, the heat of the butterfly heat sink 24 will be conducted to the outer shell 22. Subsequently, the outer shell 22 will be able to dissipate heat through the heat sink fins 62 provided in the array. When the temperature inside the inner cavity 12 is overheated, the active adjustment motor 60 arranged at the tail will be started. When the active adjustment motor 60 is started, the heat dissipation adjustment blades 59 will be rotated. When the heat dissipation adjustment blades 59 rotate, a strong suction force will be generated, and the suction force will discharge the hot air inside the butterfly heat sink 24.

[0059] When the stator 28 and the rotor 29 are rotating, the dynamic thermal management wind control unit 17 arranged at the output end will operate (the second wind control unit component 50 and the first wind control unit component 51 have the same structure, but the second wind control unit component 50 and the first wind control unit component 51 are symmetrically arranged and realize staggered operation). When the first wind control unit component 51 provided in the dynamic thermal management wind control unit 17 is started, the driving device 61 provided in the first wind control unit component 51 will be started. After the driving device 61 is started, the push rod 45 provided at the end of the telescopic motor 47 will move. When the telescopic motor 47 extends and becomes longer, the telescopic motor 47 will drive the push rod 45 to swing, thereby driving the sliding block 44 provided at the end of the push rod 45 to move in the slide groove. 43 slides inside and pushes the arc-shaped push plate 42 to move outward. When the arc-shaped push plate 42 is pushed outward, the arc-shaped push plate 42 will inhale air into its interior through the air inlet hole 18. When the arc-shaped push plate 42 moves to the outer end, the arc-shaped push plate 42 will push the movable air collecting cylinder 35 to move outward to expand the air intake volume. When the movable air collecting cylinder 35 moves to the outside, the movable air collecting cylinder 35 will drive the slider 38 to move to the convex bending portion 37, and the reset spring 39 will form a compressed state. The movable air collecting cylinder 35 will move to the outermost side along with the arc-shaped push plate 42, so that the maximum air intake volume is reached inside it, and when the first air control unit assembly 51 moves outward to inhale air, the second air control unit assembly 50 will realize external reset jetting.

[0060] When the second wind control unit assembly 50 is spraying, the movable air collecting cylinder 35 will move to the leftmost end to achieve reset, and the slider 38 will drive the movable air collecting cylinder 35 to move to the leftmost end of the movable groove 52 to achieve reset, so that its reset spring 39 will form an expansion effect, and the telescopic motor 47 will drive the push rod 45 to rotate in the opposite direction after shortening, and the sliding block 44 at the end of the push rod 45 will move to the top of the slide groove 43, so that the arc-shaped push plate 42 moves to the left end, and when the arc-shaped push plate 42 moves to the left end, it will push the internal gas to exhaust, and when the gas is exhausted, it will enter the wind accumulation cavity 55 through the outlet 33.

[0061] When the gas enters the wind accumulation cavity 55, when the gas inside the wind accumulation cavity 55 is full, the second wind control unit assembly 50 and the first wind control unit assembly 51 arranged on the outside of the outer annular cylinder 32 perform reciprocating staggered air suction, when the inhaled gas enters the wind accumulation cavity 55 through the air outlet 33, the gas will pass through the annular member 57 and be discharged from the exhaust valve 58 to the outside, and when the gas is discharged from the exhaust valve 58, the gas is discharged between the arc-shaped wind shield plates 54 provided in the array, and when the gas is discharged, the gas is blocked by the wind shield plates 53, and the gas will be discharged through the gap provided between the wind shield plates 53 and the annular cover 30, and the discharged gas will be exhausted to the outside through the bell mouth of the annular cover 30, and the exhaust port for external exhaust is directly opposite to the outer shell 22 and the inner shell 25, and when exhausting, the gas will accelerate the butterfly-shaped heat sink 24 to blow air for heat dissipation.

[0062] The gas after heat dissipation will be discharged to the outside through the active heat dissipation component 14. Because the secondary heat sink 21 is designed as an annular sparse blade, it can generate a large suction force when the secondary heat sink 21 rotates, which can effectively adsorb the heat dissipation gas, and the first-level heat sink 20 is designed as an annular dense blade. When the first-level heat sink 20 rotates, it can adsorb the heat dissipation gas more densely. The secondary heat sink 21 can quickly extract and guide the gas in the early stage, while the first-level heat sink 20 can further enhance the airflow control and exhaust efficiency in the later stage, and the first-level heat sink 20 can further concentrate the adsorption of gas in the subsequent stage to increase the flow rate and exhaust pressure of the gas, thereby ensuring that the heat dissipation gas is discharged more thoroughly and efficiently to avoid airflow stagnation or backflow.

[0063] When the device detects high temperature conditions, the active adjustment motor 60 arranged inside the inner cavity 12 will self-adjust the starting speed, so that the heat dissipation adjustment blades 59 actively dissipate heat, thereby effectively adjusting the temperature control inside the inner cavity 12, and when the heat dissipation gas inside the inner cavity 12 is discharged, the self-adjusting heat dissipation component 13 arranged at the tail will accelerate the flow of the heat dissipation gas, so that the internal temperature can effectively and quickly exchange heat.

[0064] The present invention provides a large torque explosion-proof permanent magnet motor with cooling and regulating function. The second wind control unit assembly and the first wind control unit assembly are symmetrically arranged and staggered to achieve coordinated work to achieve alternating suction and discharge of airflow. When the driving device in the first wind control unit assembly is started (extended action), the driving device will push the arc push plate to move outward. When the arc push plate moves outward, the arc push plate inhales gas into the interior through the opening on the shell, and as the arc push plate moves outward to its extreme position, the arc push plate will further push the active gas collecting cylinder to expand outward, thereby increasing the suction space and achieving the maximum suction volume. At the same time, this action will realize that when the active gas collecting cylinder expands the suction range outward, the reset spring will be in a compressed state. At the same time, the second wind control unit assembly is in the reset jet stage, and its active gas collecting cylinder moves to the leftmost position to release gas and complete the reset. During this process, when the movable air collecting cylinder moves to the leftmost end of the movable slot, the reset spring stretches to restore its original state. When the driving device of the first wind control unit assembly is retracted and shortened, the sliding block moves along the top of the slide slot to guide the arc-shaped push plate to retract to the left, completing the reset after suction. Through this alternating operation mode and by alternating the intake and exhaust of gas, the system can ensure the smooth circulation of the airflow inside the motor cavity, which can not only avoid dead corners and accumulation of airflow, but also effectively reduce the overheating and performance degradation of the motor caused by poor airflow, and through the alternating operation mode, the two wind control unit assemblies can cooperate with each other to realize continuous circulation of airflow. This design reduces the impact of a single component failure on the entire system and improves the reliability and stability of the system.

[0065] The present invention provides a large torque explosion-proof permanent magnet motor with cooling and regulating function. By providing an integrated exhaust and collecting device, when the gas enters the wind accumulation cavity and is filled, the second wind control unit assembly and the first wind control unit assembly arranged on the outside of the outer annular cylinder start to perform reciprocating and staggered air suction operations. The inhaled gas then enters the wind accumulation cavity again through the air outlet. After that, these gases will enter through a specific annular member and be discharged when reaching the exhaust valve. After the gas is released from the exhaust valve, it will flow between the arc-shaped wind shields arranged in the array. In this process, the wind shield will block the direct advancement of the gas, forcing the gas to be diverted through the gap reserved between the wind shield and the annular cover. The end of this path is the trumpet-shaped exhaust port of the annular cover, which is directly opposite to the space between the outer shell and the inner shell. In the process of gas being discharged through these structures, its flow will accelerate and produce a blowing effect on the butterfly-shaped heat sink, thereby achieving an effective heat dissipation effect. In this way, the entire device not only completes the collection and discharge of gas, but also adds a heat dissipation function. By blowing the butterfly-shaped heat sink directly by the gas, the heat dissipation efficiency can be significantly improved. The butterfly heat sink design usually increases the heat dissipation area, while the directional airflow can more effectively remove heat, reduce the operating temperature of the equipment and extend its service life.

[0066] The invention discloses a large torque explosion-proof permanent magnet motor with cooling and regulating function, which is provided with an active heat dissipation component, and the active heat dissipation component undertakes the important task of discharging the treated gas to the outside. The key to this process lies in the coordinated work of the secondary heat sink and the primary heat sink. The secondary heat sink adopts an annular sparse blade design, which quickly extracts and initially guides the gas flow when starting, and effectively adsorbs the heat dissipation gas by using the large suction force generated by it, thereby avoiding the initial stagnation of the airflow. Next, the primary heat sink intervenes with its design feature of annular dense blades, which more densely adsorbs the airflow pre-treated by the secondary heat sink during the rotation process, thereby further enhancing the control and exhaust efficiency of the airflow in the later stage. The primary heat sink not only strengthens the concentration of the gas during the adsorption process, but also significantly improves the flow speed and discharge pressure, ensuring that the heat dissipation gas can be discharged from the system more thoroughly and efficiently, effectively preventing the backflow or unnecessary stagnation of the airflow, and optimizing the flow path of the heat dissipation gas through the rapid extraction of the secondary heat sink and the intensive adsorption of the primary heat sink, so that the heat can be taken away faster, thereby ensuring the heat dissipation efficiency of the equipment. This design allows the equipment to maintain a low temperature even when running at high load, extending the service life of the equipment. The combined design of annular sparse blades and annular dense blades makes it difficult for the gas to generate eddy currents or stagnation during the flow process, while increasing the discharge pressure and effectively preventing the gas from flowing back. This ensures the continuity and stability of the heat dissipation process.
