Description

Technical Field

[0001] This invention relates to the technical field of dust prevention for motors, and in particular to a novel high-safety explosion-proof motor. Background Technology

[0002] An explosion-proof motor is a type of electric motor specifically designed for safe operation in dusty environments. Its sealed structure effectively prevents dust from entering the motor, ensuring that dust does not come into contact with the electrical sparks inside the motor, significantly reducing the risk of dust explosions and minimizing the occurrence of explosion accidents.

[0003] However, current explosion-proof motors typically use highly sealed casings to prevent dust from entering the motor. However, excessive sealing can reduce the heat dissipation of the explosion-proof motor, making it prone to overheating and damage, thus reducing its service life. Summary of the Invention

[0027] Example 1

[0028] Reference Figures 1-5In the first embodiment of the present invention, an explosion-proof drive mechanism 100 is provided to drive the device.

[0029] The explosion-proof drive mechanism 100 includes a motor body 101, an explosion-proof shell 102 is fitted on the surface of the motor body 101, and heat dissipation fins 103 are fixedly connected to the surface of the explosion-proof shell 102. The heat dissipation fins 103 are arranged in a ring and are evenly distributed. The heat dissipation fins 103 are made of copper.

[0030] Specifically, the explosion-proof shell 102 forms the first layer of sealed protection structure, which can effectively isolate external dust, flammable and explosive gases from contact with internal electric sparks and high-temperature components of the motor, meet the safety requirements of dusty environments and flammable and explosive working conditions, and avoid safety hazards such as dust explosions and motor short circuits.

[0031] Furthermore, when the motor body 101 starts running, as the core power output component, the explosion-proof shell 102 covering its surface forms the first layer of sealed protection structure, which can effectively isolate external dust, flammable and explosive gases from contact with internal electrical sparks and high-temperature components of the motor, meet the safety requirements for use in dusty environments and flammable and explosive working conditions, and avoid safety hazards such as dust explosions and motor short circuits. The annularly distributed copper heat dissipation fins 103 on the surface of the explosion-proof shell 102, relying on the high thermal conductivity of copper, can quickly absorb and conduct the heat generated by the motor body 101 during operation, increase the heat dissipation area, achieve basic passive heat dissipation, and prevent heat from accumulating inside the explosion-proof shell 102.

[0032] Example 2

[0033] Reference Figures 1-5 In the second embodiment of the present invention, a heat dissipation mechanism 200 is provided to achieve better heat dissipation, prevent dust from entering, and self-clean.

[0034] The heat dissipation mechanism 200 includes a heat dissipation groove 201, which is formed on the top of the inner wall of the explosion-proof housing 102. A heat dissipation frame 202 is fixedly connected inside the heat dissipation groove 201. A mounting frame 203 is provided on the top of the heat dissipation frame 202. A filter cloth 204 is provided inside the mounting frame 203. A connecting frame 205 is fixedly connected to the inner wall of the heat dissipation frame 202. Springs 206 are fixedly connected to the left and right sides of the top of the connecting frame 205. Several springs 206 are provided and are evenly distributed. The other end of the springs 206 is fixedly connected to the left and right sides of the bottom of the mounting frame 203. Limiting rods 207 are fixedly connected to the four corners of the bottom of the mounting frame 203. Limiting grooves 208 are formed on the four corners of the top of the connecting frame 205. The inner wall of the limiting groove 208 is slidably connected to the surface of the limiting rod 207. A limiting plate 209 is fixedly connected to the bottom of the limiting rod 207. The diameter of the limiting plate 209 is larger than the limit. The diameter of the inner wall of the slot 208; a rubber telescopic sleeve 210 is fixedly connected to the bottom of the mounting frame 203; the bottom of the rubber telescopic sleeve 210 is fixedly connected to the bottom of the heat dissipation frame 202; a flexible connecting sleeve 211 is sleeved on the surface of the filter cloth 204; the surface of the flexible connecting sleeve 211 is fixedly connected to the inner wall of the mounting frame 203; push rollers 212 are provided on the left and right sides of the bottom of the filter cloth 204; the top of the push rollers 212 contacts the bottom of the filter cloth 204; a support frame 213 is movably connected to the bottom of the push rollers 212; the bottom of the outer side of the support frame 213 is fixedly connected to the bottom of the left and right sides of the inner wall of the heat dissipation frame 202; a pressure check valve 214 is connected to the bottom of the front and back of the mounting frame 203; several pressure check valves 214 are provided and are distributed in a ring at equal intervals; an airflow guide plate 215 is fixedly connected to the front and back of the mounting frame 203; the airflow guide plate 215 is arc-shaped.

[0035] Specifically, while the motor generates heat during operation, the heat dissipation groove 201 on the top of the inner wall of the explosion-proof housing 102 provides space for airflow. External air can enter the interior of the heat dissipation frame 202 through the mounting frame 203, forming convection with the hot air inside the motor. The filter cloth 204 inside the mounting frame 203 performs the first filtration of the incoming air, intercepting external dust and impurities on the surface of the filter cloth 204 to achieve dustproof sealing. During the operation of the machine, continuous slight vibrations will be generated. These vibrations are transmitted to the connecting frame 205 inside the heat dissipation frame 202. The connecting frame 205 drives the mounting frame 203 to float up and down synchronously through the equally distributed springs 206. The elastic extension and contraction characteristics of the springs 206 can amplify the vibration effect, thereby shaking off the dust filtered on the filter cloth 204.

[0036] Furthermore, while the motor generates heat during operation, the heat dissipation groove 201 on the top of the inner wall of the explosion-proof housing 102 provides space for airflow. External air can enter the interior of the heat dissipation frame 202 through the mounting frame 203 and form convection with the hot air inside the motor. The filter cloth 204 inside the mounting frame 203 performs the first filtration of the incoming air, intercepting external dust and impurities on the surface of the filter cloth 204, preventing dust from entering the motor body 101 with the airflow. This ensures both airflow and heat dissipation, and also achieves dustproof sealing, solving the problem of poor heat dissipation caused by excessive sealing.

[0037] During motor operation, continuous slight vibrations are generated. These vibrations are transmitted to the connecting frame 205 inside the heat sink 202. The connecting frame 205 drives the mounting frame 203 to float up and down synchronously via evenly distributed springs 206. The elastic extension and contraction characteristics of the springs 206 amplify the vibration effect and provide a reset support for the mounting frame 203. The limiting rods 207 at the four corners of the bottom of the mounting frame 203 slide in conjunction with the limiting grooves 208 at the top of the connecting frame 205 to limit the floating trajectory of the mounting frame 203, preventing it from shifting left or right and ensuring stability during vibration. The diameter of the limiting plate 209 at the bottom of the limiting rod 207 is larger than the inner diameter of the limiting groove 208, which can prevent the limiting rod 207 from falling out of the limiting groove 208 and improve the reliability of the structural connection. The rubber telescopic sleeve 210 at the bottom of the mounting frame 203 expands and contracts synchronously with the floating of the mounting frame 203, always sealing the gap between the heat sink 202 and the mounting frame 203 to prevent dust from seeping in and further enhance the sealing effect.

[0038] During the vibration and floating process of the mounting frame 203, the filter cloth 204 vibrates up and down accordingly. The dust adhering to the surface of the filter cloth 204 falls off under the vibration, realizing the self-cleaning of the filter structure and preventing dust from clogging the pores of the filter cloth 204, which would obstruct airflow and ensure long-term heat dissipation. The push rollers 212 on both sides of the bottom of the filter cloth 204 are fixed to the inner wall of the heat dissipation frame 202 by the support frame 213. The top of the push rollers 212 is in close contact with the bottom of the filter cloth 204. When the filter cloth 204 vibrates up and down, the push rollers 212 provide support and push for the filter cloth 204, preventing the filter cloth 204 from deforming excessively due to vibration. At the same time, they help to shake off the tightly adhered dust and improve the self-cleaning efficiency. The soft connecting sleeve 211 on the surface of the filter cloth 204 tightly connects the filter cloth 204 to the inner wall of the mounting frame 203, eliminating gaps and preventing dust from entering from the joint between the filter cloth 204 and the mounting frame 203, thus ensuring the integrity of filtration.

[0039] When heat accumulates and air pressure rises inside the motor, the pressure check valves 214, which are equidistantly distributed in annular patterns on the front and back of the mounting frame 203, automatically open to quickly discharge hot air and excess air pressure from inside the motor, maintaining stable internal air pressure and preventing damage to the sealing structure caused by high internal pressure. The pressure check valves 214 only allow internal airflow to be discharged outward, preventing external air and dust from entering in the opposite direction, further enhancing the dustproof and explosion-proof effect. The arc-shaped airflow guide plates 215 on the front and back of the mounting frame 203 guide and dredge the discharged hot airflow, preventing the hot airflow from accumulating on the surface of the explosion-proof housing 102. At the same time, they guide external cold air to smoothly enter the interior of the mounting frame 203, optimizing the airflow circulation path and improving the overall heat dissipation efficiency. In addition, the blown airflow can also be blown onto the surface of the heat dissipation fins 103 through the airflow guide plates 215, thereby removing dust from the heat dissipation fins 103.

[0040] The remaining structure is the same as that in Example 1.

[0041] Example 3

[0042] Reference Figures 1-5 This is the third embodiment of the present invention, which differs from the second embodiment in that it provides a novel high-safety explosion-proof motor.

[0043] When the motor body 101 starts running, as the core power output component, the explosion-proof shell 102 covering its surface forms the first layer of sealed protection structure, which can effectively isolate external dust, flammable and explosive gases from contact with internal electric sparks and high-temperature components of the motor, meet the safety requirements of dusty environments and flammable and explosive working conditions, and avoid safety hazards such as dust explosions and motor short circuits.

[0048] In summary, during the operation of the explosion-proof drive mechanism 100, the heat dissipation mechanism 200 enables the explosion-proof drive mechanism 100 to dissipate heat better. In environments with excessive dust, the heat dissipation mechanism 200 can filter dust, preventing dust from entering the interior of the explosion-proof drive mechanism 100. At the same time, the vibration generated when the explosion-proof drive mechanism 100 starts can vibrate the heat dissipation mechanism 200, allowing the heat dissipation mechanism 200 to perform self-cleaning of its filter area.
