Description

Technical Field

[0001] The present invention relates to the technical field of motors, and particularly to an explosion-proof motor with efficient heat dissipation and its usage method. Background Technique

[0002] An explosion-proof motor is a type of motor that can be used in flammable and explosive places and does not generate electric sparks during operation. Explosion-proof motors are mainly used in coal mines, oil and natural gas, petrochemical and chemical industries. In addition, they are also widely used in departments such as textiles, metallurgy, urban gas, transportation, grain and oil processing, papermaking, and medicine. As the main power equipment, explosion-proof motors are usually used to drive pumps, fans, compressors, and other transmission machinery.

[0003] The traditional heat dissipation method of explosion-proof motors mainly relies on the heat dissipation structure of the motor itself. For example, a heat dissipation fan is set on the output shaft at the tail of the motor, and heat dissipation fins for heat dissipation are fixed on the motor housing. Driven by the heat dissipation fan, air is blown towards the heat dissipation fins, thereby disturbing the air flow outside the heat dissipation fins, and thus improving the heat dissipation of the heat dissipation fins. However, in environments such as coal mines and textiles, there is a large amount of dust and high temperature. In the case where the external environmental temperature is already high, even if forced convection by the fan is carried out, the temperature of the air entering the heat dissipation area of the motor is still high, and it cannot effectively absorb the heat dissipated by the motor, resulting in a significant reduction in the heat dissipation effect and poor heat dissipation effect. At the same time, the filter screen on the outer shell of the heat dissipation fan is also prone to blockage due to excessive dust attachment, resulting in a reduction in the air intake volume and poor heat dissipation effect of the motor. Summary of the Invention

[0018] S4: When the motor body stops running, the mobile heat dissipation component, the centrifugal resistance component and the mobile reset component stop running synchronously, so that the installation frame and the internal power-off refrigeration plate move back to the inside of the shell, and the partition is reset to block the exhaust hole again, so as to ensure the cleanliness of the components inside the shell for isolation protection.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

At the same time, when the motor body stops running, the mobile heat dissipation component, the centrifugal resistance component and the mobile reset component also stop resetting synchronously, so that the installation frame and the internal refrigeration fins with power off are moved back to the inside of the shell, and at the same time, the partition is reset to block the exhaust hole again, so as to ensure the cleanliness of the components inside the shell, and prevent external dust and impurities from entering the shell when not in use, causing damage to the internal components, thereby achieving the effect of isolation protection;

Specific embodiments

[0032] 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.

[0033] Embodiment 1: Please refer to Figure 1 - Figure 7 , an explosion-proof motor with efficient heat dissipation, including a motor body 1, a fixed seat 2 fixed at the bottom end of the motor body 1, and an axis 3 penetrating and installed inside the motor body 1. A plurality of heat sinks 4 are fixedly installed around the outer surface of the motor body 1 at equal angles. An outer casing 5 is fixedly installed on one side of the motor body 1. A plurality of air inlet holes 6 are penetrated and opened on the side of the outer casing 5 away from the motor body 1. A plurality of exhaust holes 7 are penetrated and arranged at equal angles on the side of the outer casing 5 close to the plurality of heat sinks 4. A cooling fan 24 is fixedly installed at the outer end of the axis 3 inside the outer casing 5. A mobile heat dissipation component and a cleaning component are arranged inside the outer casing 5; the mobile heat dissipation component includes a rotating disc 8 and a plurality of mounting frames 18. The rotating disc 8 is fixedly installed through the outer side of the axis 3 inside the outer casing 5. The plurality of mounting frames 18 are arranged around the outer edge of the rotating disc 8 at equal angles. A refrigeration sheet 19 is fixedly installed inside each of the plurality of mounting frames 18.

[0034] An external centrifugal contact component is provided on the rotating disk 8; the centrifugal contact component includes several contact blocks 12, and several contact blocks 12 are arranged in an equiangular and surrounding manner on the outer side of one side of the rotating disk 8. A chute 9 is penetrated and arranged inside the rotating disk 8 near several contact blocks 12, a guide rod 10 is fixedly installed inside each chute 9, a slider 11 is penetrated and slidably installed on the outer side of each guide rod 10, one end of each slider 11 is penetrated and slidably installed inside the chute 9 on the corresponding side, one side of each of the several contact blocks 12 is fixedly installed with one end of the slider 11 on the corresponding side, and the edge of one side of each of the several contact blocks 12 far from the axis 3 is arranged in an arc shape.

[0035] Specifically, due to the arc-shaped setting on one side of the contact block 12, the contact block 12 can smoothly squeeze and contact one side of the roller 16 during the centrifugal rotation and expansion process, ensuring the smoothness of the overall contact movement and avoiding the situation of movement resistance.

[0036] A positioning block 13 is fixedly installed on the inner wall of one side of the housing 5 near several contact blocks 12, and a moving and resetting component is arranged on one side of each positioning block 13; the moving and resetting component includes a sliding rod 14 and a reset spring 17. The sliding rod 14 is penetrated and slidably installed inside the positioning block 13, the reset spring 17 is penetrated and sleeved on the outer side of one side of the sliding rod 14, one end of the sliding rod 14 is fixedly connected to the outside of one of the corresponding mounting frames 18, a mounting seat 15 is fixedly installed at the end of the sliding rod 14 far from the mounting frame 18, and both ends of the reset spring 17 are installed on one side of the positioning block 13 and the mounting seat 15 respectively.

[0037] A roller 16 is rotatably installed on one side of each mounting seat 15, and one side of the roller 16 is in contact with one side of the corresponding contact block 12; a partition plate 21 is fitted and arranged on the inner wall of one side of the housing 5 near the exhaust hole 7, a connecting frame 20 is fixedly installed at the bottom end of each partition plate 21, and the bottom end of each connecting frame 20 is fixedly installed on the outside of the top end of one of the corresponding mounting frames 18.

[0038] A first conduction elastic sheet 22 is fixedly installed at the edge of one side of the top end of each mounting frame 18, the first conduction elastic sheet 22 is connected to the corresponding refrigerating sheet 19 through a wire, and a second conduction elastic sheet 23 is penetrated and fixedly installed inside one side of the housing 5 near the first conduction elastic sheet 22.

[0039] In this embodiment, when the explosion-proof motor is in use, first, the motor body 1 is fixed at the position where it is needed through bolts and the fixing seat 2. Then, the wire connecting a plurality of conducting elastic pieces two 23 in series is connected to an external power supply. After that, when in use, first control the motor body 1 to be powered on and operate, so that the axis 3 inside the motor body 1 rotates. Through the rotation of the axis 3, the cooling fan 24 inside the housing 5 is driven to rotate. At the same time, when the axis 3 rotates, it will also drive the rotating disk 8 on one side to rotate rapidly. Through the rapid rotation of the rotating disk 8, and the limiting and guiding of the guide rod 10 to the slider 11 and the sliding engagement of the slider 11 with the sliding groove 9, a plurality of sliders 11 and a plurality of abutting blocks 12 installed on the side will expand and move outward under the action of centrifugal force. When the abutting block 12 moves and expands, it will abut and squeeze the roller 16 on one side to move. Through the movement of the roller 16, the mounting seat 15, the sliding rod 14 and the mounting frame 18 on one side are driven to expand and move synchronously. As a result, the partition plate 21 installed at the top of the mounting frame 18 through the connecting frame 20 also moves synchronously away from one side of the exhaust hole 7, so that the exhaust hole 7 is opened. At the same time, the mounting frame 18 drives the refrigerating sheet 19 composed of the prior art inside to move into the exhaust hole 7. At the same time, when the partition plate 21 moves, it will drive the conducting elastic piece one 22 on one side to move synchronously, so that the conducting elastic piece one 22 contacts and conducts with the conducting elastic piece two 23 on the inner wall of the housing 5, so that the refrigerating sheet 19 starts to be powered on and operate for refrigeration. The cooling fan 24 blows the cold air generated by the refrigerating sheet 19 to the radiating fins 4 on the outer surface of the motor body 1, so that the cold air can quickly take away the heat on the radiating fins 4, thereby improving the overall heat dissipation effect in the case of higher temperature and ensuring the stable operation of the whole.

[0040] It should also be noted that when the motor body 1 stops operating, at this time the axis 3 stops rotating and the centrifugal force disappears. At this time, the reset spring 17 that was originally squeezed on one side starts to rebound. Through the rebound of the reset spring 17, the partition plate 21 is driven to move back to block the exhaust hole 7 again, and at the same time, the mounting frame 18 and the refrigerating sheet 19 are driven to move back into the housing 5. When moving back, the conducting elastic piece one 22 and the conducting elastic piece two 23 will also be separated synchronously, so that the refrigerating sheet 19 is powered off and stops refrigerating, reducing energy consumption. As a result, when the explosion-proof motor is not in use, the components inside the housing 5 can be isolated from the outside, so as to ensure the cleanliness of the components inside the housing 5 and avoid the situation that external dust and impurities enter the housing 5 when not in use, causing damage to the internal components, thereby achieving the effect of isolation and protection.

[0041] Embodiment Two: Please refer to Figure 8 - Figure 9 , this embodiment further explains Embodiment One. The cleaning component includes a rotating shaft 25 and an abutting plate 27. The rotating shaft 25 rotates through and is snap-fitted and installed at the middle position inside the side of the housing 5 far from the motor body 1, and the abutting plate 27 is fixedly installed through the side of the rotating shaft 25 close to the inner wall of the housing 5.

[0042] A resistance assembly is arranged inside the resistance plate 27; the resistance assembly includes a plurality of resistance columns 28, which are all slidably installed transversely inside one side of the resistance plate 27, and the end of the resistance column 28 close to the air inlet hole 6 is arranged in an arc shape, and a limiting cylinder 29 is fixedly installed outside the end of the resistance plate 27 located away from the air inlet hole 6, and a compression spring 30 is connected and fixed between the inner wall of one side of the limiting cylinder 29 and the outer surface of one side of the resistance column 28.

[0043] One end of the rotating shaft 25 close to the shaft center 3 is connected with a coaxial differential 26 , and the other end of the coaxial differential 26 is fixedly connected to one end of the shaft center 3 .

[0044] A limit strip 31 is longitudinally provided inside one side of the rotating shaft 25 located outside the shell 5. The limit strip 31 is arranged parallel to the contact plate 27. A guide groove 32 is longitudinally provided between the top and bottom ends of the limit strip 31. One side of the limit strip 31 is in contact with the outer surface of the shell 5.

[0045] In this embodiment, when the motor body 1 is powered on and operated, the coaxial differential 26 formed by the prior art is set, so that the axis 3 inside the motor body 1 rotates, which drives the rotating shaft 25 on one side to rotate at a relatively slow speed. When the rotating shaft 25 rotates, it drives the fixedly installed resistance plate 27 on one side and the multiple resistance columns 28 inside the resistance plate 27 to rotate synchronously. When the resistance column 28 rotates to the inside of the air inlet hole 6 on the corresponding side, the resistance spring 30 on one side of the resistance column 28 is pressed against and squeezed, so that one end of the arc-shaped resistance column 28 is inserted into the air inlet hole. 6, thereby pushing out the stuck impurities in the air inlet hole 6. After that, when the contact plate 27 continues to rotate, one side of the contact column 28 inserted into the air inlet hole 6 will contact and squeeze with the inner wall of the air inlet hole 6, so that the compression spring 30 on one side is compressed, so that the contact column 28 is moved out from the inside of the air inlet hole 6, and the next air inlet hole 6 is cleaned. According to the above process, the explosion-proof motor can clean the inside of the air inlet hole 6 in a cyclic and orderly manner when in use, thereby ensuring that the air inlet hole 6 can continuously and effectively intake air, thereby ensuring subsequent heat dissipation, without the need for manual cleaning, and ensuring the overall convenience of use of the device.

[0046] It should also be noted that, during the design, a collection box can be fixed on the side of the top of the fixing seat 2 near the limit strip 31. When the resistance column 28 expels the impurities inside the air inlet 6, the limit strip 31 on one side is installed and the guide groove 32 is set through the limit strip 31. The guide groove 32 guides the impurities to the bottom of the impurity collection box for collection and processing, thereby achieving a better overall use effect.

[0047] The present invention also provides a method for using an explosion-proof motor with high-efficiency heat dissipation, comprising the following steps:

[0048] S1: First, the motor body 1 is started, and the internal shaft 3 is rotated by the motor body 1, and the rotation of the shaft 3 drives the cooling fan 24 to rotate;

[0049] S2: When the shaft 3 rotates, it triggers the operation of the mobile heat dissipation component, the centrifugal resistance component and the mobile reset component, so that the partition 21 moves up to open the exhaust hole 7, and at the same time, the mounting frame 18 and the cooling fins 19 with internal power for cooling move to the inside of the opened exhaust hole 7, so that the cooling fan 24 blows the cold air generated by the cooling fins 19 to the heat dissipation fins 4 on the outer surface of the motor body 1, so that the cold air can quickly take away the heat on the heat dissipation fins 4, and dissipate heat efficiently;

[0050] S3: When the shaft 3 rotates, it will synchronously trigger the operation of the cleaning component and the resistance component, so as to perform cyclic and orderly resistance cleaning on the plurality of air inlet holes 6 on one side of the housing 5, ensuring that the air inlet holes 6 can continuously and effectively take in air, so as to ensure the subsequent heat dissipation;

[0051] S4: When the motor body 1 stops running, the mobile heat dissipation component, the centrifugal resistance component and the mobile reset component stop running synchronously, so that the installation frame 18 and the internal power-off refrigeration plate 19 move back to the inside of the outer shell 5, and at the same time the partition 21 resets to block the exhaust hole 7 again, so as to ensure the cleanliness of the components inside the outer shell 5 for isolation protection.

[0052] It should be noted that the reset spring 17 in the explosion-proof motor is a cylindrical helical compression spring made of piano wire (fatigue-resistant). The pre-compression amount is increased to avoid elastic force attenuation after long-term use, ensuring that the reset spring 17 can be effectively compressed and effectively reset to ensure stable operation. At the same time, the outer surface of the slide rod 14 is coated with a polytetrafluoroethylene coating to reduce friction and ensure the smooth sliding of the slide rod 14 inside the slider 11. At the same time, the conductive spring piece 1 22 and the conductive spring piece 2 23 in the explosion-proof motor are both existing arc-shaped beryllium bronze springs (which are prior art and will not be described in detail here). Through elastic settings, during rotation, due to processing errors or changes in centrifugal force, the resistance block 12 may have slight axial movement. At this time, the spring piece has sufficient elastic deformation to compensate for this movement, maintain contact pressure, and ensure connection stability.

[0053] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.

[0054] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
