Description

Technical Field

[0001] The present invention relates to the technical field of motor equipment, and in particular to a safe motor. Background Art

[0002] Safety motors, also known as explosion-proof motors, are motors that can be used in flammable and explosive places and do not generate electric sparks during operation. Explosion-proof motors are mainly used in coal mines, oil and gas, petrochemical and chemical industries. In addition, they are also widely used in textiles, metallurgy, city gas, transportation, grain and oil processing, papermaking, medicine and other sectors. As the main power equipment, explosion-proof motors are usually used to drive pumps, fans, compressors and other transmission machinery.

[0003] When the concentration of the mixture of combustible substances and air is within the explosion limit, an explosion will occur when encountering an ignition source. Industrial environments often encounter environments with high dust concentrations. When the dust concentration reaches a certain value, the heat or electric sparks generated by the operation of the motor can easily cause a dust explosion. Chinese patent CN116566106B discloses a composite dust-proof explosion-proof three-phase asynchronous motor, including a motor body, an output shaft is arranged in the motor body, a plurality of groups of heat sinks are arranged outside the motor body, and a protective tube mechanism is set on the motor body. The protective tube mechanism includes: a protective tube body, an opening at Two groups of air outlets at one end of the protection tube body, a second air filter fixedly installed at the air outlet, an air inlet opened at the other end of the protection tube body, a first air filter located at the outer port of the air inlet, a drive shaft screwed into the protection tube body, one end of the drive shaft connected to the output shaft, and a wind wheel fixedly installed on the drive shaft, the protection tube body is used to shield dust falling on the heat sink, and the driving wind wheel is used to dissipate heat from the heat sink; secondly, since several groups of heat sinks are located inside the protection tube body, dust is prevented from falling on the heat sink, thereby ensuring that the heat dissipation of the heat sink is not affected by dust.

[0004] The above solution has the following problems:

[0005] The air inlet is only arranged on one side of the protective tube body. After the air enters through the air inlet, it can only take away the heat of the heat sink that is aligned with the air inlet. The remaining heat sinks cannot directly contact the high-speed flowing air. Therefore, the heat cannot be taken away directly, and the heat dissipation efficiency is low, which leads to heat accumulation in the motor, posing a safety hazard. Summary of the invention

[0006] The content of this application is used to introduce concepts in a brief form, which will be described in detail in the detailed implementation section below. The content of this application is not intended to identify the key features or essential features of the technical solution claimed for protection, nor is it intended to limit the scope of the technical solution claimed for protection.

[0015] Specifically, the intermittent pushing device includes an eighth sliding groove fixedly arranged on the driving ring, a driving block slidably arranged on the eighth sliding groove, and a fourth spring with one end fixedly arranged on the driving block and the other end fixedly arranged on the driving ring.

[0016] Specifically, the reversing assembly includes a first gear ring fixed on the output shaft, a first gear fixed on the motor body, a second gear rotatably provided on the motor body and meshing with the first gear, a third gear rotatably provided on the motor body and coaxially provided with the second gear, a second gear ring rotatably provided on the motor body and meshing with the third gear, a reversing ring rotatably provided on the motor body and fixedly connected to the second gear ring, and a plurality of ninth slide grooves fixedly provided on the reversing ring.

[0017] Specifically, the motor body further includes a plurality of oil seals arranged on the output shaft.

[0018] The beneficial effects of the present invention are:

[0019] (1) A heat dissipation mechanism is provided to prevent the motor temperature from being too high to cause a dust explosion, and a filtering mechanism is provided to prevent dust from accumulating on the surface of the motor and affecting the heat dissipation effect; the output shaft rotates, one side of the first slide groove fits with the first slide bar, and drives the fan to rotate, generating airflow, so that the air flows from the left side to the right side. After being filtered by the filtering mechanism and humidified by the humidifying mechanism, the air contacts the heat dissipation fins to exchange heat, thereby cooling the motor. The airflow can exchange heat with all the heat dissipation fins, and the heat dissipation efficiency is high.

[0020] (2) By setting up a humidifying mechanism, the humidity of the air near the motor can be increased to avoid the generation of static sparks that may cause dust explosions. When the motor is in a dry dusty environment, static charges are easily accumulated on the surface, which in turn causes static sparks and poses a safety hazard. By setting up a humidifying mechanism, the humidity in the air can be increased to avoid the accumulation of a large amount of static charges, making it less likely to generate static sparks and at the same time improving the heat dissipation efficiency.

[0021] (3) The filter mechanism is self-cleaned by setting a cleaning mechanism; when the first filter is blocked to a certain extent, the pressure difference on both sides of the first filter is greater than the friction between the limit head and the limit groove, the limit head disengages from the limit groove and enters the fourth slide groove, the second spring is compressed, the first bracket slides on the second slide groove, and then drives the push rod to move, the push rod pushes the drive ring to move, the drive ring pushes the push ring to move, the first spring is compressed, and since the drive ring and the fan are fixedly connected by a connecting rod, the fan will also slide on the output shaft, the first slide rod enters the ninth slide groove, and then the fan rotates in the opposite direction to clean the dust on the first filter. After the drive ring moves, the intermittent push device is misaligned with the protrusion, so the valve block is always in a closed state at this time, avoiding dust from contacting the humid air and adhering to the first filter. There is no need for manual cleaning, no need to stop the motor for cleaning, and no need to reverse the output shaft for cleaning.

[0022] (4) An intermittent push device is provided. On the one hand, it can save water resources. On the other hand, due to the different rotation speeds of the output shaft and thus the different rotation speeds of the fan, the drying speed of the gauze is also different. If the valve assembly is not provided, water will continue to drip on the gauze. When the fan rotates slowly, the gauze is in a saturated state of water absorption, and the water will flow to other parts, causing short circuit damage to the device.

The motor is in a dry dusty environment, and it is easy to accumulate static electricity on the surface, which will cause static electricity sparks and pose a safety hazard. By setting up a humidifying mechanism, the humidity in the air is increased to avoid a large accumulation of static electricity, and it is not easy to generate static electricity sparks. At the same time, the heat dissipation efficiency can be improved; The cleaning mechanism is used to clean the filtering mechanism. The motor is in a dusty environment. After long-term use, a large amount of dust will adhere to the filtering mechanism, resulting in a decrease in air intake efficiency, which in turn affects the heat dissipation efficiency. By setting up a cleaning mechanism, the filtering mechanism can be automatically cleaned when it is blocked, and the attached dust can be blown away without manual cleaning, stopping the motor for cleaning, or reversing the output shaft for cleaning;

[0044] The heat dissipation mechanism includes a plurality of first slide grooves 61 fixedly arranged on the output shaft, a fan 62 sleeved on the output shaft, and a plurality of first slide bars 63 fixedly arranged on the fan and limited by the first slide grooves; the width of the first slide groove is greater than the first slide bar; the output shaft rotates, one side of the first slide groove fits with the first slide bar, and drives the fan to rotate, generating airflow, so that the air flows from the left side to the right side, and after being filtered by the filtering mechanism and humidified by the humidifying mechanism, it contacts with the heat dissipation fins to exchange heat, so that the motor is cooled down, and the airflow can exchange heat with all the heat dissipation fins, and the heat dissipation efficiency is high;

[0045] The filtering mechanism comprises a second slide groove 71 fixed on the protective shell, a first bracket 72 slidably arranged on the second slide groove, a first filter 73 fixed on the first bracket, a plurality of locking components 74 fixed on the protective shell and the first bracket, a driving component 75 fixed on the first bracket, and a second filter 76 fixed on the protective shell; the first bracket can slide on the second slide groove; the first bracket is limited by the locking component in its initial state; the first filter is used to filter air and filter dust in the inhaled air; the second filter cooperates with the cleaning mechanism to filter the air when the air flows in the reverse direction to prevent dust from entering; the driving component cooperates with the cleaning mechanism and the fan to drive the cleaning mechanism to work when the first filter is blocked by dust;

When the air passes through the gauze, it will take away the moisture on the gauze, which can increase the humidity of the flowing air, and avoid the accumulation of static electricity charge due to the friction between the air and the surface of the motor body in a high temperature and dry environment. At the same time, increasing the humidity can improve the heat dissipation efficiency; the second flow channel is set to a funnel shape, which can reduce the speed of water flowing out of the second flow channel. Since the diameter of the first flow channel is smaller than that of the third flow channel, that is, the speed of water flowing out of the second flow channel is smaller than the speed of water flowing into the first flow channel from the third flow channel, the first flow channel can be always filled with water, and each second flow channel can also have water flowing out, so that the gauze is evenly wetted, and it is prevented that the water flows out only from the middle second flow channel;

[0047] The cleaning mechanism includes a reversing assembly 91 fixed on the output shaft, a plurality of third slide grooves 92 fixed on the protective shell, a push ring 93 slidably arranged on the third slide groove, a plurality of second slide rods 94 fixed on the push ring, and a first spring 95 with one end fixed on the push ring and the other end fixed on the protective shell; the reversing assembly cooperates with the driving assembly to drive the cleaning mechanism to work when the first filter is clogged with dust, so that the fan is reversed to blow away the dust on the first filter; the push ring can slide on the third slide groove; the second slide rod is used for limiting to prevent the push ring from rotating; the first spring is a compression spring, which is used to reset the push ring and also to limit the movement of the push ring and the fan.

When the blockage reaches a certain degree, the pressure difference on both sides is greater than the friction between the limiting head and the limiting groove, the limiting head disengages from the limiting groove and enters the fourth slide groove, the second spring is compressed, and the first bracket will slide on the second slide groove, and then the cleaning mechanism is driven by the driving assembly to clean the first filter.

When the fan rotates, the drive ring is driven to rotate through the connecting rod, and the drive ring drives the intermittent pushing device to rotate and makes the valve block slide intermittently, that is, the water inlet pipe and the third flow channel are intermittently connected, which can save water resources on the one hand, and on the other hand, due to the different rotation speeds of the output shaft and the different rotation speeds of the fan, the drying speed of the gauze is also different. If the valve assembly is not set, water will continue to drip on the gauze.
