Description
Technical Field
[0001] This utility model belongs to the field of motor protection technology and relates to impact-resistant and explosion-proof motors. Background Technology
[0002] A motor, also known as an electric motor or engine, is a device that converts electrical energy into mechanical energy. Its working principle is that an energized coil rotates in a magnetic field, thereby driving the starter rotor to rotate, which in turn drives the engine flywheel and crankshaft to rotate.
[0003] For example, patent (CN211351905U) discloses an explosion-proof motor, which includes a motor stator, a motor rotor, a motor control device, and an explosion-proof housing. The motor stator and motor control device are sealed within the explosion-proof housing, and the motor rotor extends from within the housing, which is filled with inert gas. The explosion-proof motor solves the problem that existing motors have separate drive and control systems, which do not meet explosion-proof requirements.
[0004] When using the above technology, the following technical problems were found in the existing technology: When the existing motor is in use, high temperature or overload will cause high temperature to be generated inside the electric motor, resulting in material deformation, breakage or damage, which may lead to an explosion. When an explosion occurs, its metal shell will deform, which may lead to shattering. The shattered motor metal shell will cause great damage to the surrounding area through the impact of the explosion. Therefore, based on the above problems, an impact-resistant explosion-proof motor is proposed. Utility Model Content
[0005] The technical problem this invention aims to solve is that existing motors, when in use, high temperatures or overloads can cause high temperatures inside the motor, leading to material deformation, breakage, or damage, which may then cause an explosion. In the event of an explosion, the metal casing will deform, and in severe cases, it may shatter. The shattered motor metal casing can cause significant damage to the surrounding area through the impact of the explosion. Therefore, based on the above problems, an impact-resistant explosion-proof motor is proposed.
[0006] The impact-resistant and explosion-proof motor described in this utility model includes a protective housing, a drive seat detachably connected to the inner side of the protective housing, an annular frame fixedly connected to the end of the protective housing away from the drive seat, and a rotor column rotatably connected to the center of the annular frame.
[0007] A cooling component is disposed at one end of the protective housing near the rotor column, and the rotor column is used in conjunction with the cooling component.
[0008] A fracture prevention component is disposed on the outside of the protective housing and is used in conjunction with the protective housing.
[0009] The cooling assembly includes a cooling frame, an L-shaped frame, a rotating column, and a first transmission seat. The cooling frame is fixedly connected to the top end of the protective housing away from the drive seat. An L-shaped frame is fixedly connected to one end of the protective housing at a position corresponding to the cooling frame. A rotating column is rotatably connected to the center of the L-shaped frame. The end of the rotating column near the protective housing is fixedly connected to the fan blades inside the cooling frame. The end of the rotating column away from the protective housing is fixedly connected to the first transmission seat.
[0010] The cooling assembly also includes a second transmission seat, a belt, and a dustproof net. The second transmission seat is fixedly connected to the circumferential side of the rotor column and the end near the protective housing. A belt is provided between the first transmission seat and the second transmission seat. The end of the cooling rack located inside the protective housing is fixedly connected to a dustproof net.
[0011] The anti-cracking assembly includes a horizontal explosion-proof frame, a vertical explosion-proof frame, a linkage column, and a handle. Multiple horizontal explosion-proof frames are detachably connected to the outer side of the protective housing and the drive base. Multiple vertical explosion-proof frames are detachably connected to the outer side of the protective housing and the horizontal explosion-proof frames. The vertical explosion-proof frames are fixed together by cylinders. Linkage columns are rotatably connected to the inside of both sides of the drive base. A handle is fixedly connected to the end of the linkage column located on the outer side of the horizontal explosion-proof frame.
[0012] The anti-cracking assembly further includes a first bevel gear, a rotating shaft, a second bevel gear, and a first transmission gear. Multiple first bevel gears are fixedly connected to the ring side of the linkage column at a position corresponding to the vertical explosion-proof frame. A rotating shaft is rotatably connected inside the horizontal explosion-proof frame at a position corresponding to the first bevel gear. A second bevel gear is fixedly connected to the end of the rotating shaft near the linkage column. The first bevel gear and the second bevel gear are meshed together. A first transmission gear is fixedly connected to the end of the rotating shaft away from the linkage column.
[0013] The anti-cracking assembly further includes a first threaded sleeve, a second transmission gear, a snap-fit screw, a limiting post, and a second threaded sleeve. The first threaded sleeve is rotatably connected to the top of the transverse explosion-proof frame at a position corresponding to the rotation axis. The second transmission gear is fixedly connected to the annular side of the first threaded sleeve. The first transmission gear and the second transmission gear are meshed together.

The limiting post is fixedly connected to the transverse explosion-proof frame. The second threaded sleeve is rotatably connected to the inner side of the annular frame at a position corresponding to the snap-fit screw.
[0014] Compared with the prior art, the beneficial effects of this utility model are: through the structural design of the anti-fracture component, when the motor explodes, the protective shell will deform and crack due to the internal pressure. The design of the anti-fracture component will increase the strength of the protective shell and prevent the metal fragments of the broken protective shell from scattering in all directions, preventing the broken protective shell from causing damage to the area around the motor, improving the safety of the motor, and further improving the performance of the motor.
[0015] Through the structural design of the cooling components, the rotor column drives the cooling components to cool the inside of the protective housing when the motor is started. By reducing the operating temperature inside the protective housing, the risk of motor explosion is reduced, further improving the safety of motor use. Attached Figure Description

[0024] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.
[0025] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0026] Example 1
[0027] like Figures 1-4 As shown, the impact-resistant explosion-proof motor includes a protective housing 1, a drive base 2 is detachably connected to the inner side of the protective housing 1, an annular frame 3 is fixedly connected to the end of the protective housing 1 away from the drive base 2, and a rotor column 4 is rotatably connected to the center of the annular frame 3.
[0028] The cooling component is located at one end of the protective housing 1 near the rotor column 4. The rotor column 4 is used in conjunction with the cooling component. When the motor is started, the cooling component drives the rotor column 4 to cool the inside of the protective housing 1. By reducing the operating temperature inside the protective housing 1, the risk of motor explosion is reduced, and the safety of motor use is further improved.
[0029] The anti-fracture component is located on the outside of the protective housing 1. The anti-fracture component works in conjunction with the protective housing 1 to increase the strength of the protective housing 1, while preventing metal fragments from the protective housing 1 from scattering in all directions and preventing the broken protective housing 1 from causing damage to the area around the motor, thereby improving the safety of the motor.
[0030] Example 2
[0031] like Figure 1 and Figure 2As shown, in order to facilitate the reduction of the temperature generated inside the protective housing 1 during use, the cooling assembly includes a cooling frame 5, an L-shaped frame 6, a rotating column 7, and a first transmission seat 8. The cooling frame 5 is fixedly connected to the top end of the protective housing 1 away from the drive seat 2. The L-shaped frame 6 is fixedly connected to one end of the protective housing 1 at a position corresponding to the cooling frame 5. The rotating column 7 is rotatably connected to the center of the L-shaped frame 6. The end of the rotating column 7 near the protective housing 1 is fixedly connected to the fan blades inside the cooling frame 5, so as to facilitate the rotation of the fan blades inside the cooling frame 5 through the rotating column 7. The air blown out by the rotating fan blades drives the air flow inside the protective housing 1, and the air flow reduces the temperature inside the protective housing 1. In order to facilitate the rotation of the first transmission seat 8, the end of the rotating column 7 away from the protective housing 1 is fixedly connected to the first transmission seat 8.
[0032] The cooling assembly also includes a second transmission seat 9, a belt 10, and a dustproof net 11. The second transmission seat 9 is fixedly connected to the circumferential side of the rotor column 4 and the end close to the protective housing 1. A belt 10 is provided between the first transmission seat 8 and the second transmission seat 9. When the motor is in use, the rotating rotor column 4 drives the fan blades in the cooling rack 5 to reduce the temperature inside the protective housing 1. In order to prevent external dust from entering the interior of the protective housing 1, a dustproof net 11 is fixedly connected to the end of the cooling rack 5 located inside the protective housing 1.
[0033] When the motor starts working, it drives the rotor column 4 to rotate, which in turn drives the second transmission seat 9 to rotate. The second transmission seat 9 then drives the first transmission seat 8 and the rotating column 7 to rotate via the belt 10. The rotating column 7 then drives the fan blades inside the cooling rack 5 to lower the temperature inside the protective housing 1. When the motor is not in use, the fan blades inside the cooling rack 5 stop rotating. The cooling rack 5 is used simultaneously with the motor's operation. Through the design of the rotor column 4 and the cooling components, the cost of motor production is reduced. There is no need to install the drive source of the cooling rack 5 inside the protective housing 1. While reducing costs, the temperature reduction effect inside the protective housing 1 is improved, the risk of motor explosion is reduced, and the safety of motor use is further improved.
[0034] Example 3
[0035] like Figure 2 and Figure 3As shown, in order to reduce the damage caused by the motor explosion, the anti-fracture assembly includes a horizontal explosion-proof frame 12, a vertical explosion-proof frame 13, a linkage column 14, and a handle 24. Multiple horizontal explosion-proof frames 12 are detachably connected to the outer side of the protective housing 1 and the drive base 2. Multiple vertical explosion-proof frames 13 are detachably connected to the outer side of the protective housing 1 and the horizontal explosion-proof frames 12. In order to facilitate the fixing of the horizontal explosion-proof frames 12 and the vertical explosion-proof frames 13 installed outside the protective housing 1 and the drive base 2, the vertical explosion-proof frames 13 are fixed together by cylinders. The inner sides of both sides of the drive base 2 are rotatably connected to the linkage column 14. In order to facilitate the rotation of the linkage column 14, the end of the linkage column 14 located on the outer side of the horizontal explosion-proof frame 12 is fixedly connected to the handle 24.
[0036] To improve the efficiency of installing the horizontal explosion-proof frame 12 and the vertical explosion-proof frame 13, the anti-cracking assembly also includes a first bevel gear 15, a rotating shaft 16, a second bevel gear 17, and a first transmission gear 18. Multiple first bevel gears 15 are fixedly connected to the ring side of the linkage column 14 at a position corresponding to the vertical explosion-proof frame 13. The rotating shaft 16 is rotatably connected inside the horizontal explosion-proof frame 12 at a position corresponding to the first bevel gear 15. The second bevel gear 17 is fixedly connected to the end of the rotating shaft 16 near the linkage column 14. The first bevel gear 15 and the second bevel gear 17 are meshed together. The first transmission gear 18 is fixedly connected to the end of the rotating shaft 16 away from the linkage column 14. Thus, the rotation of the linkage column 14 and the first bevel gear 15 drives the second bevel gear 17 and the first transmission gear 18 to rotate.
[0037] The anti-cracking assembly also includes a first threaded sleeve 19, a second transmission gear 20, a snap-fit screw 21, a limiting post 22, and a second threaded sleeve 23. The first threaded sleeve 19 is rotatably connected to the top of the transverse explosion-proof frame 12 at a position corresponding to the rotating shaft 16. The second transmission gear 20 is fixedly connected to the annular side of the first threaded sleeve 19. To facilitate the rotation of the first threaded sleeve 19, the first transmission gear 18 and the second transmission gear 20 are meshed together. The snap-fit screw 21 is threadedly connected to the inner side of the first threaded sleeve 19. To facilitate the linear movement of the snap-fit screw 21 within the transverse explosion-proof frame 12 and the vertical explosion-proof frame 13, a limiting post 22 is slidably connected to the inner side of the snap-fit screw 21. The limiting post 22 is fixedly connected to the transverse explosion-proof frame 12. To facilitate the connection of the snap-fit screw 21 to the vertical explosion-proof frame 13, the second threaded sleeve 23 is rotatably connected to the inner side of the annular frame 3 at a position corresponding to the snap-fit screw 21.
[0038] During operation, after the horizontal explosion-proof frame 12 and the vertical explosion-proof frame 13 are installed outside the protective housing 1 and the drive base 2, the handle 24 is rotated in sequence. The handle 24 then drives the linkage column 14 and the first bevel gear 15 to rotate. The first bevel gear 15 then drives the rotating shaft 16 and the first transmission gear 18 to rotate via the second bevel gear 17. The first transmission gear 18 then drives the first threaded sleeve 19 to rotate via the second transmission gear 20. The first threaded sleeve 19 then drives the locking mechanism, which is limited by the limiting column 22. The screw 21 moves toward the position close to the second threaded sleeve 23, and then engages with the second threaded sleeve 23 after the screw 21 moves into the vertical explosion-proof frame 13. This fixes the horizontal explosion-proof frame 12 and the vertical explosion-proof frame 13 to the outside of the protective housing 1 and the limiting post 22. This will increase the strength of the protective housing 1 and prevent the metal fragments of the broken protective housing 1 from scattering in all directions, preventing the broken protective housing 1 from causing damage to the area around the motor, improving the safety of the motor, and further improving the performance of the motor.
