Description

Technical Field

[0001] The present invention relates to the technical field of motor dust removal, and specifically to an explosion-proof motor with an automatic dust removal function. Background Art

[0002] Explosion-proof motors are widely used in places with dangerous environments such as flammable and explosive gases and dust, such as the petrochemical, coal mining, and pharmaceutical industries. In these working environments, dust is likely to accumulate on the surface of the motor, which not only affects the heat dissipation performance of the motor but may also pose safety hazards due to dust accumulation. When dust accumulates on the surface of the motor, it forms a heat-insulating layer, hindering the heat inside the motor from dissipating to the surrounding environment. When the motor operates, a large amount of heat is generated. If the heat cannot be dissipated in a timely and effective manner, the temperature inside the motor will continue to rise. Excessive temperature will not only reduce the efficiency of the motor and shorten its service life but may also lead to a decline in motor performance and an increased risk of electrical failures.

[0003] Conventional motor dust removal mainly relies on manual cleaning at regular intervals. This method consumes labor and time costs, and the cleaning frequency cannot be accurately grasped, making it impossible to achieve real-time detection and timely dust cleaning. Summary of the Invention

[0004] The purpose of the present invention is to provide an explosion-proof motor with an automatic dust removal function to solve the problems raised in the prior art.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

[0006] The explosion-proof motor includes a motor body, a dust removal mechanism, and a fan blade adjustment mechanism. The motor body is connected to the dust removal mechanism, the motor body is connected to the fan blade adjustment mechanism, and the dust removal mechanism is connected to the fan blade adjustment mechanism.

[0007] In the present invention, an explosion-proof motor is proposed. This motor has the function of automatic dust removal. The motor body is used to normally drive other devices so that other devices can operate normally. The dust removal mechanism performs dust removal operations on the surface of the motor body, and the fan blade adjustment mechanism is used to assist the dust removal mechanism to better perform dust removal on the motor body.

[0008] Furthermore, the motor body includes a housing, a dust cover, a base, and connecting columns. The middle of the housing is made of insulating material, and the inner and outer rings of the housing are made of metal material. The housing and the dust cover are tightly connected. A dust-proof cavity is provided inside the dust cover. There are no less than four connecting columns. One end of the connecting column is tightly connected to the base, and the end of the connecting column far from the base is tightly connected to the housing. The housing is connected to the dust removal mechanism, the dust cover is connected to the dust removal mechanism, and the base is connected to the dust removal mechanism. The base is connected to the fan blade adjustment mechanism. The motor body also includes a stator, a rotor, and a driving fan. The stator is tightly connected to the housing. The rotor is placed inside the stator and passes through both ends of the housing. The rotor is connected to the dust cover. One end of the rotor is placed in the dust-proof cavity. The driving fan is connected to the dust cover and placed in the dust-proof cavity. The driving fan is tightly connected to the rotor placed in the dust-proof cavity. The rotor is connected to the dust removal mechanism.

[0009] In the motor body, the housing, as the external mechanism of the motor, plays the role of supporting and fixing various internal components of the motor, provides an installation foundation for components such as the stator and rotor, keeps their relative fixed position relationship, ensures the stability of the motor structure, and at the same time can also protect the internal components such as the stator and rotor of the motor from the influence of external environmental factors, preventing these factors from causing damage to the inside of the motor and affecting the normal operation of the motor. The housing is installed on the base through connecting columns for fixing the position. A dust cover is tightly connected behind the housing. The dust cover is used to prevent dust, debris, etc. from entering the inside of the motor. In some working environments with more dust, the dust cover can effectively block dust. And the housing is tightly connected to the stator. The stator is provided with a rotor. One end of the rotor is in the dust-proof cavity and is tightly connected to the driving fan. The other end of the rotor extends out of the housing and is connected to the device to be driven. After the motor starts, the stator generates a rotating magnetic field. The rotor induces an electric current under the action of the rotating magnetic field and interacts with the magnetic field to generate an electromagnetic force, so that the rotor rotates under the action of torque. During the rotation process, the driving fan is driven to rotate together. The driving fan generates wind, which can cool the housing tightly connected to the dust cover, help the motor dissipate heat, improve the heat dissipation efficiency, and extend the service life of the motor.

[0010] Furthermore, the dust removal mechanism includes a fixed bottom plate and a detection device. The detection device is connected to the housing. The fixed bottom plate is placed on the ground and tightly connected to the base. The detection device is connected to the fixed bottom plate. The detection device includes a conductive brush and a driving hydraulic cylinder. There are several conductive brushes. The brush heads of the conductive brushes are in contact with the housing. The tails of several conductive brushes are tightly connected to the output end of the driving hydraulic cylinder through a fixed rod. The fixed end of the driving hydraulic cylinder is tightly connected to the fixed bottom plate.

[0011] In the dust removal mechanism, the fixed bottom plate is used to place the motor body and the dust removal mechanism. The dust removal mechanism is used to remove dust from the surface of the casing. The dust on the surface of the casing is detected by a detection device. Since the middle of the casing is an insulating material, the inner and outer circles of the casing will not affect each other. When the outer circle is used for dust detection, the electromagnetic field generated when the motor is started will not cause inaccurate measurement data. The detection device can be driven to start when the motor is driven. The conductive brush has good conductivity. After the conductive brush and the casing are in contact, power is turned on. The current will form a loop through the conductive brush and the casing. If there is no dust on the surface, the current and voltage are in a stable state; if there is dust, the dust will form an isolation layer between the conductive brush and the casing. Because dust is generally a non-conductive or poorly conductive material, it will cause the resistance between the conductive brush and the casing to increase. When the voltage is constant, the current will decrease. The position of the dust is determined according to the change in current. At the same time, the conductive brush is driven by the hydraulic cylinder to move on the surface of the casing, so that the casing can be fully inspected. At the same time, the conductive brush is only set on the upper half of the casing. Since the lower half faces the base, no dust will stick to the casing.

[0012] Furthermore, the dust removal mechanism also includes a dust removal device, which is connected to the dust cover, and the dust removal device is connected to the rotor. The dust removal device includes a first gear, a second gear, a fixing ring and a connecting rod. The rotor is placed in the dust chamber and is fastened with the first gear on one end. The upper wall of the dust chamber is provided with an opening. The second gear is meshed with the first gear through gears. The second gear is rotatably connected to the connecting rod. The connecting rod is fastened to the surface of the dust cover. The second gear is meshed with the fixing ring through gears. The diameter of the fixing ring is larger than the diameter of the casing. The dust removal device also includes a support rod. The dust removal device is connected to the fixed base plate. The surface of the fixing ring is provided with a clamping rod. The cam is provided with two support rods, and the two support rods are inverted "L" shape. One end of the support rod away from the fixed ring is fastened to the fixed base plate. The dust removal device also includes a dust removal fan, a driving rotating rod, a third gear and a driving tooth chain. The driving rotating rod is provided with a plurality of driving rotating rods, and the number of driving rotating rods, dust removal fans and third gears is the same. The number of driving tooth chains is one less than that of the driving rotating rod. The driving rotating rod is fastened to the fixed ring, and the third gear is rotatably connected to the end of the driving rotating rod away from the fixed ring. The dust removal fan is fastened to the third gear, and adjacent third gears are connected through a driving tooth chain transmission.

[0013] The dust removal mechanism further includes a dust removal device. The first gear is fixedly connected to the rotor. The first gear meshes with the second gear, and the second gear meshes with the third gear. The second gear is fixed by a connecting rod. After the rotor rotates, the first gear is driven to rotate together. Through meshing, the third gear is also driven to rotate together. The third gear is rotationally connected to the fixed ring through a driving rod. The fixed ring is fixed by a support rod. A dust removal fan is fixedly connected to the third gear. Therefore, during the rotation of the third gear, the dust removal fan will also be driven to rotate together, generating dust removal wind, which can be used to remove dust from the surface of the casing. At the same time, a driving chain is meshed with the adjacent third gear. Therefore, after one third gear rotates, the other third gears will also be driven to rotate together, and the corresponding dust removal fans will be driven to generate dust removal wind to remove dust from the casing.

[0014] Further, the fan blade adjusting mechanism includes a telescopic rod, a synchronous ring and a guide vane. The fan blade adjusting mechanism is connected to the dust removal device. The telescopic rod is connected to the dust removal device. There are two telescopic rods. One end of the telescopic rod is fixedly connected to the fixed ring. The two telescopic rods are symmetrically arranged with respect to the straight line passing through the center of the fixed ring. The end of the telescopic rod away from the fixed ring is fixedly connected to the synchronous ring. There are several guide vanes. A sliding groove is provided on the outer wall of the guide vane. Several protrusions are provided on the inner ring of the synchronous ring. The number of protrusions on the synchronous ring is the same as that of the guide vanes. The synchronous ring is slidably connected to the outer wall sliding groove of the guide vane through the protrusions.

[0015] In the fan blade adjusting mechanism, this mechanism is used to change the blowing direction of the dust removal wind generated by the dust removal fan. The guide vane is slidably connected to the fixed ring. The adjacent guide vanes are connected by the synchronous ring. When one guide vane changes its angle due to the elongation or shortening of the telescopic rod, the other guide vanes will change the same angle together. When the detection device detects dust, according to its position relative to the dust removal device, the telescopic rod elongates or shortens, causing the guide vane to change its angle so that the dust removal wind can better blow to the place with dust.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: After the present invention is started, by setting a driving fan blade, during the operation of the explosion-proof motor, in addition to driving other devices, the rotor can also make the driving fan blade rotate to generate cooling air, which cools the casing of the fastening connection surface with the dust-proof cover, helps the motor dissipate heat, improves the heat dissipation efficiency, and extends the service life of the motor; by setting a detection device, since the middle of the casing is made of insulating material, when detecting dust on the outer ring, the electromagnetic induction generated during the motor startup will not cause inaccurate measurement data. The detection device is used to detect the dust on the surface of the casing. By setting a conducting brush, after the conducting brush contacts the casing and is electrified, the current will form a loop through the conducting brush and the casing. If there is no dust on the surface, the current and voltage will be in a stable state; if there is dust, the dust will form an isolation layer between the conducting brush and the casing. Since dust is generally a non-conductive or poorly conductive substance, it will cause an increase in the resistance between the conducting brush and the casing. Under a certain voltage, the current will decrease. According to the change of the current, the position of the dust is determined, and then the driving hydraulic cylinder is used to drive the conducting brush to move on the surface of the casing for comprehensive detection; by setting a dust removal device and a fan blade adjustment mechanism, after the detection is completed, the explosion-proof motor is restarted, and the output end drives the device to be driven. The rotor part placed in the dust-proof cover not only makes the driving fan blade rotate to cool the casing, but also drives the first gear to rotate. Through meshing, the third gear rotates, thereby driving the dust removal fan to rotate to generate dust removal air. The remaining third gears are driven to start through the driving chain, driving the corresponding dust removal fans to generate dust removal air. Then, according to the dust situation detected by the detection device, the angle of the deflector is adjusted through the telescopic rod. According to the position of the dust from the dust removal device, the telescopic rod extends or retracts, causing the deflector to change the angle, so that the dust removal air can better blow to the place with dust, completing automatic dust removal.

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] Embodiment: As Figures 1-8 shown, the present invention provides a technical solution for an explosion-proof motor with an automatic dust removal function. The explosion-proof motor includes a motor body 1, a dust removal mechanism 2, and a fan blade adjustment mechanism 3. The motor body 1 is connected to the dust removal mechanism 2, the motor body 1 is connected to the fan blade adjustment mechanism 3, and the dust removal mechanism 2 is connected to the fan blade adjustment mechanism 3.

[0028] In the present invention, an explosion-proof motor is proposed. The motor has the function of automatic dust removal. The motor body 1 is used to normally drive other devices so that other devices can operate normally. The dust removal mechanism 2 performs dust removal operations on the surface of the motor body 1. The fan blade adjustment mechanism 3 is used to assist the dust removal mechanism 2 to better perform dust removal on the motor body 1.

[0029] The motor body 1 includes a housing 11, a dust cover 12, a base 13 and connecting columns 14. The middle of the housing 11 is made of insulating material, and the inner and outer rings of the housing 11 are made of metal material. The housing 11 and the dust cover 12 are fixedly connected. A dust-proof cavity 121 is provided inside the dust cover 12. There are no less than four connecting columns 14. One end of the connecting column 14 is fixedly connected to the base 13, and the end of the connecting column 14 away from the base 13 is fixedly connected to the housing 11. The housing 11 is connected to the dust removal mechanism 2, the dust cover 12 is connected to the dust removal mechanism 2, and the base 13 is connected to the dust removal mechanism 2. The base 13 is connected to the fan blade adjusting mechanism 3. The motor body 1 further includes a stator 15, a rotor 16 and a driving fan blade 17. The stator 15 is fixedly connected to the housing 11. The rotor 16 is placed inside the stator 15. The rotor 16 penetrates through both ends of the housing 11. The rotor 16 is connected to the dust cover 12. One end of the rotor 16 is placed in the dust-proof cavity 121. The driving fan blade 17 is connected to the dust cover 12. The driving fan blade 17 is placed in the dust-proof cavity 121. The driving fan blade 17 is fixedly connected to the rotor 16 placed in the dust-proof cavity 121. The rotor 16 is connected to the dust removal mechanism 2.

[0030] In the motor body 1, the housing 11 serves as the external mechanism of the motor, playing the role of supporting and fixing various components inside the motor, providing an installation foundation for components such as the stator 15 and the rotor 16, enabling them to maintain a relatively fixed positional relationship, ensuring the stability of the motor structure. At the same time, it can also protect components such as the stator 15 and the rotor 16 inside the motor from the influence of external environmental factors, preventing these factors from damaging the inside of the motor and affecting the normal operation of the motor. The housing 11 is installed on the base 13 through the connecting columns 14 for fixing the position. A dust cover 12 is fixedly connected to the back of the housing 11. The dust cover 12 is used to prevent dust, debris, etc. from entering the inside of the motor. In some working environments with more dust, the dust cover 12 can effectively block dust. And the housing 11 is fixedly connected to the stator 15. There is a rotor 16 inside the stator 15. One end of the rotor 16 is in the dust-proof cavity 121 and is fixedly connected to the driving fan blade 17. The other end of the rotor 16 extends out of the housing 11 and is connected to the device to be driven. After the motor is started, the stator 15 generates a rotating magnetic field. The rotor 16 induces a current under the action of the rotating magnetic field and interacts with the magnetic field to generate an electromagnetic force, so that the rotor 16 is subjected to a torque and rotates. During the rotation process, the driving fan blade 17 is driven to rotate together. The driving fan blade 17 generates wind, which can cool the housing 11 connected to the dust cover 12, help the motor dissipate heat, improve the heat dissipation efficiency, and extend the service life of the motor.

[0031] The dust removal mechanism 2 includes a fixed bottom plate 21 and a detection device 22. The detection device 22 is connected to the machine housing 11. The fixed bottom plate 21 is placed on the ground and is firmly connected to the base 13. The detection device 22 is connected to the fixed bottom plate 21. The detection device 22 includes a conductive brush 221 and a driving hydraulic cylinder 222. A plurality of conductive brushes 221 are provided. The brush heads of the conductive brushes 221 are in contact with the machine housing 11. The tails of the plurality of conductive brushes 221 and the output end of the driving hydraulic cylinder 222 are firmly connected through a fixed rod. The fixed end of the driving hydraulic cylinder 222 is firmly connected to the fixed bottom plate 21.

[0032] In the dust removal mechanism 2, the fixed bottom plate 21 is used to place the motor body 1 and the dust removal mechanism 2. The dust removal mechanism 2 is used to remove dust from the surface of the machine housing 11. The dust on the surface of the machine housing 11 is detected by the detection device 22. Since the middle of the machine housing 11 is made of insulating material, the inner and outer rings of the machine housing 11 will not affect each other. When detecting dust on the outer ring, the electromagnetic field generated during motor startup will not cause inaccurate measurement data. The detection device 22 can be driven to start when the motor is driving. The conductive brush 221 has good electrical conductivity. After the conductive brush 221 is in contact with the machine housing 11, it is energized, and the current will form a loop through the conductive brush 221 and the machine housing 11. If there is no dust on the surface, the current and voltage are in a stable state; if there is dust, the dust will form an isolation layer between the conductive brush 221 and the machine housing 11. Since dust is generally a non-conductive or poorly conductive substance, the resistance between the conductive brush 221 and the machine housing 11 will increase. Under a certain voltage, the current will decrease. The position of the dust is determined according to the change in current. At the same time, the driving hydraulic cylinder 222 is used to drive the conductive brush 221 to move on the surface of the machine housing 11, so that the machine housing 11 can be comprehensively inspected. At the same time, the conductive brush 221 is only arranged on the upper half of the machine housing 11. Since the lower half faces the base 13, there will be no dust sticking to the machine housing 11.

[0033] The dust removal mechanism 2 also includes a dust removal device 23, which is connected to the dust cover 12, and the dust removal device 23 is connected to the rotor 16. The dust removal device 23 includes a first gear 231, a second gear 232, a fixing ring 233 and a connecting rod 234. The rotor 16 is placed in the dust chamber 121 and is fastened to the first gear 231 at one end. The upper wall of the dust chamber 121 is provided with an opening. The second gear 232 and the first gear 231 are meshed through gears. The second gear 232 and the connecting rod 234 are rotatably connected. The connecting rod 234 is fastened to the surface of the dust cover 12. The second gear 232 and the fixing ring 233 are meshed through gears. The diameter of the fixing ring 233 is larger than the diameter of the casing 11. The dust removal device 23 also includes a support rod 235. The dust removal device 23 is connected to the fixed base plate 21. The surface of the fixing ring 233 is provided with a card groove. The fixed ring 233 and the support rod 235 are fastened together by a slot. Two support rods 235 are provided. The two support rods 235 are inverted "L" shape. One end of the support rod 235 away from the fixed ring 233 is fastened together with the fixed base plate 21. The dust removal device 23 also includes a dust removal fan 236, a driving rotating rod 237, a third gear 238 and a driving gear chain 239. There are a plurality of driving rotating rods 237. The number of driving rotating rods 237, dust removal fans 236 and third gears 238 is the same. The number of driving gear chains 239 is one less than that of driving rotating rods 237. The driving rotating rod 237 is fastened together with the fixed ring 233. The third gear 238 is rotatably connected to one end of the driving rotating rod 237 away from the fixed ring 233. The dust removal fan 236 is fastened together with the third gear 238. Adjacent third gears 238 are transmission-connected through the driving gear chain 239.

[0034] The dust removal mechanism 2 also includes a dust removal device 23, the first gear 231 is tightly connected to the rotor 16, the first gear 231 and the second gear 232 are meshed, the second gear 232 and the third gear 238 are meshed, the second gear 232 is fixed by a connecting rod 234, after the rotor 16 rotates, the first gear 231 is driven to rotate together, through meshing, the third gear 238 is also driven to rotate together, the third gear 238 is rotatably connected to the fixing ring 233 through the driving rotating rod 237, and the fixing ring 233 is fixed by the support rod 235. The third gear 238 is fixedly connected with a dust removal fan 236. Therefore, during the rotation of the third gear 238, the dust removal fan 236 will also be rotated together to generate dust removal wind, and the dust removal wind can be used to remove dust from the surface of the casing 11. At the same time, a driving gear chain 239 is engaged with the adjacent third gears 238. Therefore, after one third gear 238 rotates, other third gears 238 will also be rotated together, and the corresponding dust removal fans 236 will be driven together to generate dust removal wind to remove dust from the casing 11.

[0035] The fan blade adjusting mechanism 3 includes a telescopic rod 31, a synchronous ring 32 and a deflector 33. The fan blade adjusting mechanism 3 is connected to the dust removal device 23. The telescopic rod 31 is connected to the dust removal device 23. There are two telescopic rods 31. One end of the telescopic rod 31 is tightly connected to the fixed ring 233. The two telescopic rods 31 are symmetrically arranged with respect to the straight line where the center of the fixed ring 233 is located. The end of the telescopic rod 31 far from the fixed ring 233 is tightly connected to the synchronous ring 32. There are several deflectors 33. A sliding groove is provided on the outer wall of the deflector 33. Several protrusions are provided on the inner ring of the synchronous ring 32. The number of protrusions on the synchronous ring 32 is the same as that of the deflector 33. The synchronous ring 32 is slidably connected to the outer wall sliding groove of the deflector 33 through the protrusions.

[0036] In the fan blade adjusting mechanism 3, this mechanism is used to change the blowing direction of the dust removal air generated by the dust removal fan 236. The deflector 33 is slidably connected to the fixed ring 233. Adjacent deflectors 33 are connected through the synchronous ring 32. When one deflector 33 changes its angle due to the elongation or shortening of the telescopic rod 31, the other deflectors 33 will change the same angle together. When the detection device 22 detects dust, according to its position relative to the dust removal device 23, the telescopic rod 31 extends or contracts, so that the deflector 33 changes its angle, enabling the dust removal air to better blow to the place where there is dust.

[0037] Working principle of the present invention: After the present invention is started, by setting the driving fan blade 17, during the operation of the explosion-proof motor, in addition to driving other devices, the rotor 16 can also cause the driving fan blade 17 to rotate, generating cooling air to cool the casing 11 of the fastening connection surface with the dust-proof cover 12, helping the motor dissipate heat, improving the heat dissipation efficiency, and extending the service life of the motor; by setting the detection device 22, since the middle of the casing 11 is made of insulating material, when detecting dust on the outer ring, the measurement data will not be inaccurate due to the electromagnetic field generated when the motor starts. The detection device 22 detects the dust on the surface of the casing 11. By setting the conducting brush 221, after the conducting brush 221 contacts the casing 11 and is electrified, the current will form a loop through the conducting brush 221 and the casing 11. If there is no dust on the surface, the current and voltage are in a stable state; if there is dust, the dust will form an isolation layer between the conducting brush 221 and the casing 11. Dust is generally a non-conductive or poorly conductive substance, so it will cause an increase in the resistance between the conducting brush 221 and the casing 11. Under a certain voltage, the current will decrease. According to the change of the current, the position of the dust is determined, and then the driving hydraulic cylinder 222 is used to drive the conducting brush 221 to move on the surface of the casing 11 for comprehensive detection; by setting the dust removal device 23 and the fan blade adjustment mechanism 3, after the detection is completed, the explosion-proof motor is restarted, and the output end drives the device to be driven. The part of the rotor 16 placed in the dust-proof cover 12 not only makes the driving fan blade 17 rotate to cool the casing 11, but also drives the first gear 231 to rotate. Through meshing, the third gear 238 rotates, thereby driving the dust removal fan 236 to rotate to generate dust removal air. The remaining third gears 238 are driven by the driving chain 239 to start, driving the corresponding dust removal fans 236 to generate dust removal air. Then, according to the dust situation detected by the detection device 22, the angle of the deflector 33 is adjusted by the telescopic rod 31. According to the position of the dust from the dust removal device 23, the telescopic rod 31 extends or retracts, causing the deflector 33 to change the angle, so that the dust removal air can better blow to the place with dust, completing automatic dust removal.

Therefore, in any aspect, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description.
