Description

Technical Field

[0001] The invention belongs to the technical field of explosion-proof motors, and in particular relates to a heat-dissipating explosion-proof motor. Background Art

[0002] An explosion-proof motor is a motor that can be used in flammable and explosive places and does not generate sparks during operation. It is mainly used in coal mines, oil and gas, petrochemical and chemical industries, and is usually used to drive pumps, fans, compressors and other transmission machinery. Due to the special operating environment of explosion-proof motors, the inside of explosion-proof motors needs to be sealed, which leads to poor heat dissipation of explosion-proof motors.

[0003] The common heat dissipation method of explosion-proof motors is air cooling, which is mainly a sealed air cooling structure. The sealed air cooling can ensure the heat dissipation efficiency of the motor under the premise of ensuring the sealing of the motor. For example, the invention patent with the publication number CN114157073B has the following problems in its heat dissipation technology; first, since the fan is connected to the motor through the transmission shaft, the increase in the motor operating frequency will drive the fan speed to increase, and the accumulation speed of the working heat of the motor will also increase. However, since the air intake of the dustproof net is fixed, when the fan speed increases to a certain value, the unit air intake of the fan is equal to the maximum air intake of the dustproof net, and the fan heat dissipation efficiency reaches a peak value. If the motor speed increases again at this time, the working heat of the motor will increase accordingly, while the heat dissipation efficiency of the fan remains unchanged, and the heat dissipation efficiency of the fan to the motor will decrease. The heat of the motor will accumulate in the motor housing, accelerating the aging of the motor circuit, and there are safety hazards; second, since the explosion-proof motor works in dusty environments such as mines, the dustproof net is easily blocked by dust, resulting in a decrease in the air intake of the dustproof net. When the speed of the motor and the fan remains unchanged, the heat dissipation efficiency of the fan to the motor gradually decreases. Summary of the invention

[0004] The purpose of the present invention is to provide a heat dissipation explosion-proof motor to solve the technical problems in the prior art in view of the deficiencies in the prior art.

[0005] The purpose of the present invention can be achieved by the following technical solutions: a heat dissipation explosion-proof motor, which includes a housing and a stator and a rotor therein, a sealed front cover and a sealed rear cover are respectively installed at the front and rear ends of the housing, the rotor is connected to the fan through a transmission shaft, and an adjustment component is installed inside the sealed rear cover;

[0006] The adjustment component includes an adjustment frame and ventilation pipes at both ends of the adjustment frame, light plates are slidably installed at both ends of the adjustment frame, both sides of the light plates are connected to the side walls of the adjustment frame through sealing rubber, the adjustment chamber between the sealing rubbers is connected to the ventilation pipe, the light plates are connected to both ends of the dust screen, fixed rollers and movable rollers are installed inside the adjustment frame, the fixed rollers and movable rollers prop up the dust screen, the dust screen is propped up in a folded shape, and the light plates are connected to the rack plate;

[0007] A heat conducting pipe is installed inside the shell and is communicated with the sealed rear cover. A transmission assembly is installed on the transmission shaft of the fan. The transmission assembly includes a movable gear, which is meshed with a rack plate.

[0008] As a further optimization or improvement of this solution, the adjustment component also includes a reset spring and a rotating sleeve, a push rod is installed on the movable roller, a transmission block is installed on the push rod, the rotating sleeve is rotatably installed inside the adjustment frame, a spiral groove is opened inside the rotating sleeve, the transmission block cooperates with the spiral groove, a reset spring is connected between the movable roller and the rotating sleeve, and a rubber ring is installed on the rotating sleeve.

[0009] As a further optimization or improvement of the present solution, the adjustment assembly further includes a center plate, and the rack plate is slidably installed in the center plate.

[0010] As a further optimization or improvement of the present solution, a dust collecting groove is installed on the lightweight board, and the dust collecting groove is located below the dust isolation net.

[0011] As a further optimization or improvement of this solution, the transmission assembly also includes an electromagnetic ring and a suction plate. A rotating sleeve is installed on the rotating shaft of the fan, and the suction plate is slidably installed in the rotating sleeve. The suction plate is coaxially connected to the gear, and the electromagnetic ring is installed inside the rotating sleeve.

[0012] As a further optimization or improvement of this solution, the suction plate is connected to the inner wall of the rotating sleeve via a short-range spring.

[0013] As a further optimization or improvement of this solution, a fixed ring sleeve is installed on the shell, one end of the heat pipe is open, and a mesh plate is installed on the other end of the heat pipe. The open end of the heat pipe is connected to the sealed rear cover, and the other end of the heat pipe is fixedly installed on the fixed ring sleeve.

[0014] Beneficial effects of the present invention:

[0015] (1) The operation of the motor drives the fan to rotate, so that the fan draws external air into the sealed rear cover through the dust screen. Then the fan drives the air inside the sealed rear cover to circulate through the heat conduction pipe to achieve heat dissipation of the motor;

[0016] In one of the cases, when the motor speed increases, the fan speed increases accordingly, and at the same time the working heat of the motor increases. During this process, the electromagnetic ring starts, and the electromagnetic ring attracts the suction plate, causing the suction plate to slide along the rotating sleeve, and the gear on the suction plate moves accordingly. When the gear engages with the rack plate, the fan drives the lightweight plate to move relatively away through the gear. As the lightweight plate moves, the lightweight plate stretches the dust screen, increasing the vertical area of ​​the dust screen, and the air intake of the dust screen increases accordingly. While the fan speed increases, the ventilation volume of the dust screen increases accordingly. Therefore, the heat dissipation efficiency of the fan is improved accordingly, so that the fan can effectively dissipate the increased working heat of the motor and avoid heat accumulation inside the motor affecting its circuit.

[0017] In another case, when the motor speed remains unchanged, the fan speed also remains unchanged. Since the mesh holes on the dust screen are blocked, the air intake of the dust screen is reduced. When the fan suction effect remains unchanged, the fan draws gas inside the regulating chamber through the ventilation pipe. As the air inside the regulating chamber is extracted, the lightweight plate moves relatively, causing the lightweight plate to stretch the dust screen, thereby increasing the vertical area of ​​the dust screen and improving the ventilation volume of the dust screen, thereby effectively ensuring the heat dissipation efficiency of the fan.

[0018] (2) The present invention stretches the dust screen by moving the lightweight plate, so that the dust screen drives the movable roller to move and compress the reset spring. At this time, the movable roller drives the push rod to move synchronously. As the push rod moves, the transmission block on the push rod begins to cooperate with the spiral groove inside the rotating sleeve. At this time, the movement of the push rod and the transmission block will drive the rotating sleeve to rotate; when the lightweight plate moves in the opposite direction, the dust screen first returns to its previous state. Due to the rubber ring installed on the rotating sleeve, there is resistance when the rotating sleeve rotates. Therefore, there is a delay in the process of the reset spring rebounding to drive the movable roller to reset. Before this, since the dust screen lacks the support of the movable roller, the dust screen is in a loose state. As the reset spring gradually rebounds and drives the transmission block to disengage from the spiral groove of the rotating sleeve, the reset spring rebounds and drives the movable roller to eject toward the direction of the dust screen. The movable roller impacts the loose dust screen, so that the dust on the dust screen falls off and falls into the dust collecting tank for collection. After the movable roller impacts the dust screen, it props up the dust screen, so that the dust screen returns to its previous state. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] See also Figure 1-Figure 7 A heat dissipation explosion-proof motor comprises a housing 1 and a stator 8 and a rotor 7 therein, a sealed front cover 2 and a sealed rear cover 3 are respectively installed at the front and rear ends of the housing 1, the rotor 7 is connected to a fan 10 through a transmission shaft, and an adjustment component 9 is installed inside the sealed rear cover 3;

[0034] The adjustment component 9 includes an adjustment frame 901 and ventilation pipes 902 located at both ends of the adjustment frame 901. Lightweight plates 905 are slidably installed at both ends of the adjustment frame 901. Both sides of the lightweight plates 905 are connected to the side walls of the adjustment frame 901 through sealing rubbers 904. The adjustment chamber 903 between the sealing rubbers 904 is connected to the ventilation pipe 902. The lightweight plates 905 are connected to both ends of the dust-proof net 908. Fixed rollers 907 and movable rollers 906 are installed inside the adjustment frame 901. The fixed rollers 907 and movable rollers 906 prop up the dust-proof net 908. The dust-proof net 908 is propped up in a folded shape. The lightweight plates 905 are connected to the rack plate 912.

[0035] A heat pipe 6 is installed inside the housing 1 , and the heat pipe 6 is connected to the sealed rear cover 3 . A transmission assembly 11 is installed on the transmission shaft of the fan 10 . The transmission assembly 11 includes a movable gear 1105 , and the gear 1105 is meshed with the rack plate 912 .

[0036] Specifically, a base 4 is installed at the bottom of the shell 1, and the shell 1 is fixed on the work surface through the base 4.

[0037] It should be noted that the sealed front cover 2 and the sealed rear cover 3 seal the rotor 7 and the stator 8 inside the housing 1 to avoid sparks when the motor is running, so that the motor can be used in coal mining, oil and gas, petrochemical and chemical industries. The heat pipe 6 is arranged around the rotor 7 and the stator 8 to absorb the heat generated by the operation of the motor.

[0038] When in use, the motor drives the fan 10 to rotate, so that the fan 10 draws external air into the sealed rear cover 3 through the dust screen 908, and then the fan 10 drives the air inside the sealed rear cover 3 to circulate through the heat pipe 6 to achieve heat dissipation of the motor;

[0039] When the motor speed increases, the speed of the fan 10 increases accordingly, and the working heat of the motor increases. During this process, the electromagnetic ring 1102 starts, and the electromagnetic ring 1102 attracts the suction plate 1103, causing the suction plate 1103 to slide along the rotating sleeve 1101, and the gear 1105 on the suction plate 1103 moves accordingly. When the gear 1105 engages with the rack plate 912, the fan 10 drives the lightweight plate 905 to move relatively away through the gear 1105. As the lightweight plate 905 moves, the lightweight plate 905 stretches the dust screen 908, thereby increasing the vertical area of ​​the dust screen 908, and the air intake of the dust screen 908 increases accordingly. While the speed of the fan 10 increases, the ventilation volume of the dust screen 908 increases accordingly. Therefore, the heat dissipation efficiency of the fan 10 is improved accordingly, so that the fan 10 can effectively dissipate the increased working heat of the motor and avoid the accumulation of heat inside the motor affecting its circuit.

[0040] Since the explosion-proof motor works in dusty environments such as mines, the mesh holes on the dust screen 908 are easily blocked. When the motor speed remains unchanged, the speed of the fan 10 also remains unchanged. Since the mesh holes on the dust screen 908 are blocked, the air intake of the dust screen 908 is reduced. When the air suction effect of the fan 10 remains unchanged, the fan 10 draws the gas inside the adjustment chamber 903 through the ventilation pipe 902. As the air inside the adjustment chamber 903 is extracted, the lightweight plate 905 moves relatively, so that the lightweight plate 905 drives the dust screen 908 to be stretched, thereby increasing the vertical area of ​​the dust screen 908 and improving the ventilation volume of the dust screen 908, thereby effectively ensuring the heat dissipation efficiency of the fan 10.

[0041] See also Figure 9-11 The adjustment component 9 also includes a reset spring 910 and a rotating sleeve 914. A push rod 913 is installed on the movable roller 906, and a transmission block 916 is installed on the push rod 913. The rotating sleeve 914 is rotatably installed inside the adjustment frame 901. A spiral groove is opened inside the rotating sleeve 914, and the transmission block 916 cooperates with the spiral groove. A reset spring 910 is connected between the movable roller 906 and the rotating sleeve 914, and a rubber ring 915 is installed on the rotating sleeve 914.

[0042] Since the explosion-proof motor works in a dusty environment such as a mine, the mesh holes on the dust isolation net 908 are easily blocked, so the dust on the dust isolation net 908 needs to be cleaned frequently.

[0043] The present invention stretches the dust-proof net 908 by moving the light plate 905, so that the dust-proof net 908 drives the moving roller 906 to move and compress the reset spring 910. At this time, the moving roller 906 drives the push rod 913 to move synchronously. As the push rod 913 moves, the transmission block 916 on the push rod 913 starts to cooperate with the spiral groove inside the rotating sleeve 914. At this time, the movement of the push rod 913 and the transmission block 916 will drive the rotating sleeve 914 to rotate. When the light plate 905 moves in the opposite direction, the dust-proof net 908 first returns to its previous state. Due to the rubber ring 915 installed on the rotating sleeve 914, there is resistance when the rotating sleeve 914 rotates. Therefore, the reset spring 91 0 There is a delay in the process of the movable roller 906 being reset due to the rebound. Before this, since the dust-proof net 908 lacks the support of the movable roller 906, the dust-proof net 908 is in a loose state. As the reset spring 910 gradually rebounds and drives the transmission block 916 to disengage from the spiral groove of the rotating sleeve 914, the reset spring 910 rebounds and drives the movable roller 906 to eject toward the dust-proof net 908. The movable roller 906 impacts the loose dust-proof net 908, so that the dust on the dust-proof net 908 is detached and falls into the dust collecting groove 909 for collection. After the movable roller 906 impacts the dust-proof net 908, the dust-proof net 908 is propped up, so that the dust-proof net 908 is restored to its previous state.

[0044] See also Figure 6 The adjustment assembly 9 also includes a center plate 911, and a rack plate 912 is slidably installed in the center plate 911.

[0045] It should be noted that a center plate 911 is installed on the adjustment frame 901 , and a rack plate 912 on the lightweight plate 905 is slidably installed inside the center plate 911 .

[0046] See also Fig. 9 A dust collecting groove 909 is installed on the lightweight board 905, and the dust collecting groove 909 is located below the dust isolation net 908.

[0047] It should be noted that a cover plate is provided on the dust collecting trough 909, which is not marked in the drawings and does not affect the integrity of the present invention. The main purpose of the cover plate is to prevent the collected dust from being blown up.

[0048] See also Figure 7-Figure 8 The transmission assembly 11 also includes an electromagnetic ring 1102 and a suction plate 1103. A rotating sleeve 1101 is installed on the rotating shaft of the fan 10. The suction plate 1103 is slidably installed in the rotating sleeve 1101. The suction plate 1103 is coaxially connected to the gear 1105. The electromagnetic ring 1102 is installed inside the rotating sleeve 1101.

[0049] Specifically, the suction plate 1103 is connected to the inner wall of the rotating sleeve 1101 via a short-range spring 1104 .

[0050] It should be noted that the fan 10 is connected to the rotating sleeve 1101 through a reducer and a speed sensor. The speed sensor is used to measure the speed of the fan 10 in real time. The speed sensor is connected to the electromagnetic ring 1102. When the speed of the fan 10 changes, the electromagnetic ring 1102 starts; when the gear 1105 is engaged with the rack plate 912, the rotation of the fan 10 shaft is transmitted to the gear 1105 through the reducer, so that the rack plate 912 drives the lightweight plate 905 to move slowly, thereby avoiding the situation where the fan 10 rotates too fast and causes the tooth surface to wear when the gear 1105 is engaged with the rack plate 912.

[0051] See also Figure 1-Figure 3 A fixing ring sleeve 5 is installed on the shell 1, one end of the heat pipe 6 is open, and a mesh plate is installed on the other end of the heat pipe 6. The open end of the heat pipe 6 is connected to the sealed rear cover 3, and the other end of the heat pipe 6 is fixedly installed on the fixing ring sleeve 5.

[0052] It should be noted that the mesh plate on the heat pipe 6 can prevent dust from entering the sealed rear cover 3 through the heat pipe 6 when the motor is idle.

[0053] The implementation principle of the present invention is as follows: when in use, the motor drives the fan 10 to rotate, so that the fan 10 draws external air into the sealed rear cover 3 through the dust screen 908, and then the fan 10 drives the air inside the sealed rear cover 3 to circulate through the heat pipe 6 to achieve heat dissipation of the motor;

[0054] When the motor speed increases, the speed of the fan 10 increases accordingly, and the working heat of the motor increases. During this process, the electromagnetic ring 1102 starts, and the electromagnetic ring 1102 attracts the suction plate 1103, causing the suction plate 1103 to slide along the rotating sleeve 1101, and the gear 1105 on the suction plate 1103 moves accordingly. When the gear 1105 engages with the rack plate 912, the fan 10 drives the lightweight plate 905 to move relatively away through the gear 1105. As the lightweight plate 905 moves, the lightweight plate 905 stretches the dust screen 908, thereby increasing the vertical area of ​​the dust screen 908, and the air intake of the dust screen 908 increases accordingly. While the speed of the fan 10 increases, the ventilation volume of the dust screen 908 increases accordingly. Therefore, the heat dissipation efficiency of the fan 10 is improved accordingly, so that the fan 10 can effectively dissipate the increased working heat of the motor and avoid the accumulation of heat inside the motor affecting its circuit.

[0055] When the motor speed remains unchanged, the speed of the fan 10 also remains unchanged. Since the mesh holes on the dust screen 908 are blocked, the air intake of the dust screen 908 is reduced. When the air suction effect of the fan 10 remains unchanged, the fan 10 draws the gas inside the regulating chamber 903 through the ventilation pipe 902. As the air inside the regulating chamber 903 is extracted, the lightweight plate 905 moves relatively, causing the lightweight plate 905 to stretch the dust screen 908, thereby increasing the vertical area of ​​the dust screen 908 and improving the ventilation volume of the dust screen 908, thereby effectively ensuring the heat dissipation efficiency of the fan 10.

[0056] Specifically, regarding the dust collection on the dust-proof net 908, the present invention moves and stretches the dust-proof net 908 by the lightweight plate 905, so that the dust-proof net 908 drives the movable roller 906 to move and compress the reset spring 910. At this time, the movable roller 906 drives the push rod 913 to move synchronously. As the push rod 913 moves, the transmission block 916 on the push rod 913 begins to cooperate with the internal spiral groove of the rotating sleeve 914. At this time, the movement of the push rod 913 and the transmission block 916 will drive the rotating sleeve 914 to rotate; when the lightweight plate 905 moves in the opposite direction, the dust-proof net 908 first returns to its previous state. Due to the rubber ring 915 installed on the rotating sleeve 914, there is resistance when the rotating sleeve 914 rotates. Therefore, there is a delay in the process of the reset spring 910 rebounding and driving the movable roller 906 to reset. Before this, the dust screen net 908 is in a loose state because the dust screen net 908 lacks the support of the movable roller 906. As the reset spring 910 gradually rebounds and drives the transmission block 916 to disengage from the spiral groove of the rotating sleeve 914, the reset spring 910 rebounds and drives the movable roller 906 to be ejected toward the dust screen net 908. The movable roller 906 impacts the loose dust screen net 908, so that the dust on the dust screen net 908 falls off and falls into the dust collecting groove 909 for collection. After the movable roller 906 impacts the dust screen net 908, the dust screen net 908 is propped up, so that the dust screen net 908 returns to its previous state.

[0057] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
