[0042] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only 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 ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0043] The present invention provides Figures 1 to 11The explosion-proof vibration motor for mining shown in the figure comprises a support assembly 1, wherein a motor body 2 is arranged inside the support assembly 1, wherein the motor body 2 comprises a vibration motor 203 and a heat dissipation filter plate 201, wherein a support 202 is arranged at the bottom of the vibration motor 203, wherein the bottom of the support 202 is connected to the upper part of the support assembly 1, wherein a slide groove is arranged on the surface of the heat dissipation filter plate 201, wherein a sliding rod 212 is arranged inside the slide groove, wherein a first cleaning ring 204 is arranged at the upper part of the sliding rod 212, wherein a telescopic rod 209 is arranged at the inner side of the first cleaning ring 204, wherein a second cleaning ring 207 is arranged at the bottom of the sliding rod 212, wherein the second cleaning ring 207 is arranged inside the heat dissipation filter plate 201 along the axis of the first cleaning ring 204, wherein a sliding ring 208 is arranged at the inner side of one end of the heat dissipation filter plate 201 away from the first cleaning ring 204, wherein a rotating ring 211 is arranged inside the sliding ring 208, wherein a cleaning knife 210 is arranged on the side of the rotating ring 211 facing the first cleaning ring 204, wherein the end of the cleaning knife 210 away from the rotating ring 211 is chamfered.

[0044] like Figure 5 As shown, in order to facilitate the cleaning of the inner side of the second cleaning ring 207, a sliding groove is provided on one side of the rotating ring 211 for the cleaning knife 210 to slide inside it, and the rotating ring 211 is connected to one end of the cleaning knife 210 through the sliding groove. The number of cleaning knives 210 is provided in six groups, and each group of cleaning knives 210 is circumferentially arranged on the side of the rotating ring 211 facing the first cleaning ring 204. When in use, the angle of the cleaning knife 210 is controlled by the driving motor so that one side edge of the cleaning knife 210 contacts the inner side of the second cleaning ring 207, and then cooperates with the rotation of the rotating ring 211 to achieve the effect of scraping off impurities and dust on the inner side of the second cleaning ring 207.

[0045] like Figures 4 to 5 As shown, in order to control the rotating ring 211 and the edge of one side of the cleaning knife 210 to contact the inner side of the second cleaning ring 207 and achieve the effect of cleaning the inner side, a micro motor is provided on one side of the sliding ring 208, and the output end of the micro motor and one side of the rotating ring 211 are mutually transmitted. A sliding block is provided on the side of the sliding ring 208 close to the heat dissipation filter plate 201, and the side of the sliding block away from the sliding ring 208 is movably arranged inside the electric control slide rail 205. When in use, the angle of the cleaning knife 210 on the rotating ring 211 is controlled by turning on the micro motor so that the edge of the cleaning knife 210 is in contact with the inner side of the second cleaning ring 207. The inner surfaces of the two cleaning rings 207 are completely fitted together, thereby achieving the effect of cleaning impurities and dust on the inner side of the second cleaning ring 207. At the same time, by controlling the electric control slide rail 205, the sliding block is moved along the surface of the heat dissipation filter plate 201 toward the second cleaning ring 207, so that the second cleaning ring 207 is cleaned by the cleaning knife 210 during the cleaning process of the heat dissipation filter plate 201, thereby avoiding the situation where a large amount of dust and impurities adhere to the surface of the second cleaning ring 207 and contaminate the heat dissipation filter plate 201 due to long-term use of the second cleaning ring 207.

[0046] like Figure 4 and Figure 7 As shown, in order to improve the heat dissipation capacity of the heat dissipation filter plate 201 and effectively intercept dust and impurities in the working environment, a plurality of heat dissipation holes 206 are provided on the heat dissipation filter plate 201 to dissipate the heat on the surface of the vibration motor 203 in time. The diameter of the heat dissipation hole 206 is adapted to the telescopic rod 209, and a compression spring 214 is provided inside the telescopic rod 209, and a slider 213 is provided at the other end of the compression spring 214. The elongation of the telescopic rod 209 is controlled by the compression spring 214 and the slider 213. When in use, the heat generated by the vibration motor 203 will be directly discharged to the outside through the heat dissipation holes 206 on the heat dissipation filter plate 201, thereby achieving the heat dissipation effect of the vibration motor 203. In addition, since the vibration motor 203 There will be a lot of dust and impurities in the operating environment. Even if there is a dust-proof net 106 on the outside to intercept the dust and impurities, a lot of dust and impurities will still accumulate on the heat dissipation filter plate 201. When dust accumulates in the heat dissipation holes 206 and reduces the effective aperture of the heat dissipation holes 206, the heat generated by the vibration motor 203 cannot be discharged to the outside in time, causing the surface temperature of the vibration motor 203 to rise and be damaged. At this time, the electric control slide rail 205 is controlled to make the sliding rod 212 move along the inside of the electric control slide rail 205 toward the direction of the rotating ring 211. In this process, the dust in the heat dissipation holes 206 is cleaned by the telescopic rod 209 on the first cleaning ring 204, so as to achieve the effect of cleaning the dust and impurities in the heat dissipation holes 206.

[0047] like Figure 5As shown, in order to cooperate with the sliding rod 212 and the electric control slide rail 205 to control the first cleaning ring 204 to move along the surface of the heat dissipation filter plate 201 in the direction of the rotating ring 211, the telescopic rod 209 is controlled to always contact the inside of the heat dissipation hole 206 to achieve the purpose of cleaning the inside of the heat dissipation hole 206. The telescopic rod 209 is located above the heat dissipation hole 206, and the end of the telescopic rod 209 close to the heat dissipation filter plate 201 is in contact with the heat dissipation hole 206 for cleaning the heat dissipation hole 206. The number of telescopic rods 209 is six groups, and each group of telescopic rods 209 is arranged in a circular array on the inner side of the first cleaning ring 204. The positions of the telescopic rods 209 and the heat dissipation holes 206 are adapted to each other, so that the telescopic rods 209 are always consistent with the positions of the heat dissipation holes 206 when moving. This arrangement makes the first cleaning ring 20 When the sliding rod 212 moves along the inside of the electric control slide rail 205, the end of the telescopic rod 209 close to the heat dissipation aluminum plate is always in contact with the heat dissipation hole 206 on the surface thereof, and when the compression spring 214 in the telescopic rod 209 is in the initial state, the telescopic rod 209 and the heat dissipation hole 206 are kept in the inserted state, and when the telescopic rod 209 is moving, the end of the telescopic rod 209 close to the heat dissipation filter plate 201 moves to the edge of the inner diameter of the heat dissipation hole 206 to be compressed, and then the compression spring 214 is compressed after being compressed, and at this time, the end of the telescopic rod 209 close to the heat dissipation filter plate 201 is tightly pressed against the surface of the heat dissipation aluminum plate until it moves to the next heat dissipation hole 206, and the compression spring 214 quickly releases the pressure to keep the telescopic rod 209 in the initial state, and in this process, the impurities inside the heat dissipation hole 206 are cleaned.

[0048] like Figure 8As shown, in order to control the distance between the first cleaning ring 204 and the second cleaning ring 207, so that the first cleaning ring 204 and the second cleaning ring 207 are completely in contact with the surface of the heat dissipation filter plate 201, the purpose of scraping and cleaning the surface of the heat dissipation filter plate 201 is achieved, an electromagnet 215 is provided inside the sliding rod 212, and a magnetic block 216 is provided on one side of the electromagnet 215. There are two magnetic blocks 216, and each magnetic block 216 is mirror-imaged on the upper and lower sides of the electromagnet 215. A return spring is provided on the side of each magnetic block 216 away from the electromagnet 215, and there are two return springs, each return spring is mirror-imaged on the upper and lower sides of the electromagnet 215, and each magnetic block 216 is provided with a connection on the side away from the electromagnet 215 Rod, and one end of each connecting rod away from the magnetic block 216 is respectively connected to one side of the first cleaning ring 204 and the second cleaning ring 207. When in use, the electromagnet 215 in the sliding rod 212 is controlled to make the magnetic block 216 in the sliding rod 212 move toward each other, so as to adjust the distance between the first cleaning ring 204 and the second cleaning ring 207, so that the inner side of the first cleaning ring 204 is tightly fitted with the outer side of the heat dissipation filter plate 201, and the outer side of the second cleaning ring 207 is tightly fitted with the inner side of the heat dissipation filter plate 201, and then the first cleaning ring 204 and the second cleaning ring 207 are controlled to move along the surface of the heat dissipation filter plate 201 through the cooperation of the sliding rod 212 and the electric control slide rail 205, so as to achieve the effect of scraping off dust and impurities on the surface of the heat dissipation filter plate 201.

[0049] It should be noted that when the first cleaning ring 204 and the second cleaning ring 207 are in the initial state, the first cleaning ring 204 and the second cleaning ring 207 are respectively located on the upper part of the heat dissipation filter plate 201 and inside the heat dissipation filter plate 201, and the first cleaning ring 204 and the second cleaning ring 207 do not contact the surface of the heat dissipation filter plate 201.

[0050] When the magnetic force of the electromagnet 215 is in the positive pole, the two magnetic blocks 216 located on the electromagnet 215 move along the sliding rod 212 in the direction away from the electromagnet 215, the first cleaning ring 204 is located on the upper part of the heat dissipation filter plate 201, and the second cleaning ring 207 is located inside the heat dissipation filter plate 201. When the magnetic force of the electromagnet 215 is in the negative pole, the two magnetic blocks 216 located on the electromagnet 215 move along the sliding rod 212 in the direction close to the electromagnet 215 and fit with the electromagnet 215. The surfaces of the first cleaning ring 204 and the heat dissipation filter plate 201 fit each other, and the second cleaning ring 207 fits with the inner side of the heat dissipation filter plate 201.

[0051] like Figure 6As shown, in order to better cooperate with the magnetic block 216 in the slide bar of the electromagnet 215 so that the first cleaning ring 204 and the second cleaning ring 207 can be completely attached to the surface of the heat dissipation filter plate 201, a shrink belt 217 is provided inside the first cleaning ring 204, and the shrink belt 217 is arranged at the breakpoint of the first cleaning ring 204 to adjust the diameter of the first cleaning ring 204, and a shrink belt 217 is provided inside the second cleaning ring 207, and the shrink belt 217 is arranged on the second cleaning ring 207. The breakpoint is used to adjust the diameter of the second cleaning ring 207. When in use, when the electromagnet 215 controls the magnetic block 216 to move away from the electromagnet 215, the contraction band 217 in the first cleaning ring 204 will be in a stretched and expanded state, and at this time the diameter of the first cleaning ring 204 is larger than the diameter of the heat dissipation filter plate 201, and at the same time the contraction band 217 in the second cleaning ring 207 will be in a contracted state, and the diameter of the second cleaning ring 207 is smaller than the diameter of the heat dissipation filter plate 201. In this state, due to vibration When the vibration motor 203 is in working state for a long time, dust impurities in the air will be adsorbed on the surface of the heat dissipation filter plate 201 on the vibration motor 203, which will cause the thermal conductivity of the heat dissipation filter plate 201 to decrease, and most of the heat will be absorbed by the dust impurities on its surface into the inside, so that the heat generated by the vibration motor 203 cannot be discharged to the outside in time. In addition, dust impurities will also accumulate around the heat dissipation holes 206, thereby reducing the effective aperture of the heat dissipation holes 206, resulting in the heat dissipation filter plate 201 being unable to discharge heat through the heat dissipation holes 206, causing the vibration motor 203 to be in a high temperature state for a long time and thus damaged. At this time, the temperature value detected by the temperature sensor in the vibration motor 203 reflects the accumulation of dust impurities on the heat dissipation filter plate 201, and the cleaning strategy of the first cleaning ring 204 and the second cleaning ring 207 for the heat dissipation filter plate 201 is adjusted in real time according to the detected temperature value, so as to prevent the heat dissipation filter plate 201 from being blocked in the heat dissipation holes 206 due to dust accumulation, resulting in heat being unable to be dissipated in time and causing damage to the motor. The specific steps are as follows:

[0052] When the temperature sensor detects that the temperature of the vibration motor 203 is at a preset value, it means that the heat dissipation filter plate 201 is not in a blocked state and the heat dissipation rate is normal, and no adjustment is made.

[0053] When the temperature sensor detects that the temperature of the vibration motor 203 is higher than the preset value, it means that the dust and impurities on the surface of the heat dissipation filter plate 201 are already in a state of accumulation, which makes it impossible to discharge the heat generated by the vibration motor 203 to the outside in time, causing the temperature of the vibration motor 203 to rise. At this time, the electromagnets 215 in the S1 area and the S2 area in the control sliding rod 212 are both set to negative poles, and the two symmetrically arranged magnetic blocks 216 inside are controlled to move toward the electromagnets 215 in the S1 area and the S2 area. At this time, the first cleaning ring 204 will shrink toward the inside of the heat dissipation filter plate 201, and at the same time, with the elastic effect of the shrinking belt 217, the diameter of the first cleaning ring 204 and the diameter of the heat dissipation filter plate 201 are adapted to each other, and the inner side of the first cleaning ring 204 moves to the outer surface of the heat dissipation filter plate 201 and maintains a fit therewith, and the telescopic rod 209 located on the first cleaning ring 204 close to the heat dissipation filter plate 201 will be inserted into the inner side of the heat dissipation hole 206 (please participate in the specific insertion state Fig.10 ), and the second cleaning ring 207 moves toward the inner diameter surface of the heat dissipation filter plate 201 in coordination with the movement of the magnetic block 216, and the shrinkage band 217 located in the second cleaning ring 207 will stretch outward, so that the diameter of the second cleaning ring 207 is adapted to the heat dissipation filter plate 201, so that the side of the second cleaning ring 207 facing the heat dissipation filter plate 201 will fit together with the inner side of the heat dissipation filter plate 201. At this time, the electric control slide rail 205 in the slide groove on the heat dissipation filter plate 201 is controlled to make the surface of the sliding rod 212 move along the electric control slide rail 205 toward the direction of the rotating ring 211. At this time, since the first cleaning ring 204 and the second cleaning ring 207 are in contact with the inner and outer sides of the heat dissipation filter plate 201, the dust and impurities accumulated on the heat dissipation filter plate 201 are scraped off, and the effect of cleaning it is achieved, so that the heat dissipation filter plate 201 can timely discharge the heat generated by the vibration motor 203 to the outside.

[0054] When the temperature sensor detects that the temperature of the vibration motor 203 is still higher than the preset value, it means that although the dust and impurities on the surface of the heat dissipation filter plate 201 have been scraped off, some of the impurities will be pushed into the heat dissipation holes 206 when scraping off the dust and impurities, resulting in the accumulation of impurities inside the heat dissipation holes 206. The effective aperture of the heat dissipation holes 206 gradually shrinks, resulting in the inability of heat to be discharged to the outside at a normal speed. At this time, the magnetic force of the electromagnet 215 in the S1 area of ​​the sliding rod 212 is adjusted to the negative pole, so that the first cleaning ring 204 cooperates with the shrinkage belt 217 to move in the direction close to the heat dissipation filter plate 201, and the first cleaning ring 204 will be completely attached to the surface of the heat dissipation filter plate 201, and the electromagnet 215 in the S2 area is controlled to be set to the positive pole, so that the second cleaning ring 207 cooperates with the shrinkage belt 217 to move in the direction away from the heat dissipation filter plate 201, and the second cleaning ring 207 will be located inside the heat dissipation filter plate 201. At this time, the telescopic rod 209 is fully inserted into the inner side of the heat dissipation hole 206 (please refer to the specific insertion state). Fig.11 ), and then the sliding rod 212 is controlled by the electric control slide rail 205 to move in the direction of the rotating ring 211. During the movement, the telescopic rod 209 will frequently push down the dust and impurities in the heat dissipation holes 206 on the heat dissipation filter plate 201. At the same time, the impurities and dust after being pushed out will pass through the heat dissipation filter plate 201 and contact the top of the second cleaning ring 207, thereby achieving the effect of cleaning the dust and impurities in the heat dissipation holes 206. In addition, the telescopic rod 209 detects the blockage in the heat dissipation holes 206 through the compression spring 214 inside it during the movement of following the first cleaning ring 204. The specific process is as follows:

[0055] When the telescopic rod 209 is inserted into the heat dissipation hole 206, the compression spring 214 is not in the initial state (the initial state of the compression spring 214 is the uncompressed state). It is detected that the compression spring 214 is still in the compressed state after being inserted into the heat dissipation hole 206, indicating that the heat dissipation hole 206 here is in a blocked state. The electromagnet 215 in the S1 area is controlled to release the negative pole strong magnetism, so that the first cleaning ring 204 is tightly attached to the surface of the heat dissipation filter plate 201. At this time, the telescopic rod 209 will limit each other with the heat dissipation hole 206 on the heat dissipation filter plate 201, so as to achieve the effect of detecting blockage and positioning. At this time, the sliding block and the sliding ring 208 are controlled by the electric control slide rail 205 to move in the direction of the first cleaning ring 204, so that the rotating ring 211 will contact the second cleaning ring 207. When the rotating ring 211 contacts the second cleaning ring 207, the rotating ring 211 is located at the rotating ring 207. The cleaning knife 210 on the ring 211 will be located above the second cleaning ring 207. At this time, the driving motor is turned on and the cleaning knife 210 is controlled to rotate along the output shaft of the driving motor, and the edges on both sides of the cleaning knife 210 will frequently knock on the heat dissipation filter plate 201 and cooperate with the telescopic rod 209 to achieve the effect of cleaning the dust and impurities in the heat dissipation hole 206. When the cleaning is completed, the telescopic rod 209 will be fully inserted into the heat dissipation hole 206, and penetrate the heat dissipation hole 206 to contact the upper part of the cleaning knife 210. At this time, the cleaning knife 210 is continued to be controlled by the driving motor to continue to rotate, and pressure is frequently applied to the bottom end of the telescopic rod 209, so that the compression spring 214 in the telescopic rod 209 is frequently compressed and released, so that the telescopic rod 209 frequently retracts and reciprocates in the heat dissipation hole 206, so as to achieve the effect of cleaning the dust and impurities adhering to the inner wall of the heat dissipation hole 206.

[0056] It is worth noting that when the cleaning knife 210 rotates and hits the bottom end of the telescopic rod 209, vibration is generated, so that dust and impurities on the first cleaning knife 210 can be shaken off by vibration, thereby achieving the effect of cleaning the outer surface of the first cleaning ring 204.

[0057] After the surface and inner side of the heat dissipation filter plate 201 are cleaned, the sliding ring 208 is controlled to move along the electric control slide rail 205 toward the first cleaning ring 204, and then the electromagnet 215 in the area of ​​S2 is controlled to be set to a negative pole, so that the second cleaning ring 207 will be tightly fitted with the inner side of the heat dissipation filter plate 201, and then the sliding ring 208 is controlled to move toward the second cleaning ring 207 through the electric control slide rail 205. During this process, the cleaning knife 210 will first contact one side of the second cleaning ring 207. Since the end of the cleaning knife 210 away from the rotating ring 211 is set to a chamfered shape, the second cleaning ring 207 will squeeze the cleaning knife 210 so that the cleaning knife 210 is located on the inner side of the second cleaning ring 207, and the micro motor is controlled to control the rotating ring 211 to rotate to cooperate with the cleaning knife 210 to scrape and clean along the surface of the second cleaning ring 207.

[0058] In addition, when it is necessary to clean the outer side of the second cleaning ring 207, the electromagnet 215 in the control S2 area is set to the positive pole, so that the second cleaning ring 207 moves away from the heat dissipation filter plate 201, and cooperates with the shrink belt 217 to reduce the diameter of the second cleaning ring 207, so that the second cleaning ring 207 is located on the inner side of the heat dissipation filter plate 201 and does not contact the inner side of the heat dissipation filter plate 201. At this time, the control sliding ring 208 moves toward the direction of the second cleaning ring 207 through the electric control slide rail 205. When the rotating ring 211 contacts the second cleaning ring 207, the cleaning blade on the rotating ring 211 210 will be located above the second cleaning ring 207, and the bottom of the cleaning knife 210 will contact the outer surface of the second cleaning ring 207, and the micro motor will be controlled to control the rotating ring 211 and the cleaning knife 210 to rotate, so as to achieve the effect of cleaning the outer surface of the second cleaning ring 207, and prevent the second cleaning ring 207 from cleaning the dust and impurities on the heat dissipation filter plate 201 for a long time, and a large amount of dust and impurities will be attached to its surface. When used again, the dust and impurities attached to the second cleaning ring 207 will re-adhere to the surface of the heat dissipation filter plate 201, causing secondary pollution.

[0059] like Figure 2As shown, in order to support the motor body 2, the device is fixed in the working environment through the support component 1 to ensure that it will not be displaced due to its own vibration during long-term work. The support component 1 includes a support plate 101, a fixing block 102 is provided on the upper surface of the support plate 101, a handle is provided on one side of the fixing block 102, an N-shaped frame 103 is provided at the bottom of the support plate 101, and a bottom plate 107 is provided at the bottom of the N-shaped frame 103, a mounting plate 104 is provided on one side of the bottom plate 107, and fixing screws are provided above the mounting plate 104, a dust net 106 is provided on one side of the N-shaped frame 103, and a C-shaped guard plate 105 is provided on the front of the N-shaped frame 103. When in use, the support component 1 The cooperation between the mounting plate 104 and the fixing screws fixes the device in its working environment. The mature fixing technology of the fixing screws ensures that the device as a whole will not be displaced due to its own vibration. At the same time, the dust net 106 is used to intercept dust and impurities in the working environment to prevent a large amount of dust and impurities generated during vibration from entering the vibration motor 203 and causing damage. In addition, the N-shaped frame 103 is used to protect the internal vibration motor 203 to prevent the vibration motor 203 from being damaged by falling or being hit. When it needs to be moved, you only need to lift the handle on the top of the support plate 101 to easily pull it up and complete the purpose of moving.

[0060] The present invention also provides a method for using the explosion-proof vibration motor for mining, and the specific steps of the method are as follows:

[0061] S1. First, the mounting plate 104 in the support assembly 1 is matched with the fixing screws to fix it in the specified working environment. Then, the dustproof net 106 located on the N-shaped frame 103 is used to dissipate the internal heat to the outside in time, and at the same time, the dust and impurities in the working environment are intercepted to prevent excessive dust and impurities from entering the interior and damaging the motor. In addition, the fixing block 102 cooperates with the handle to facilitate the movement of the vibration motor 203. The C-shaped guard plate 105 is used to protect the internal vibration motor 203 when it is hit or dropped.

[0062] S2, secondly, the first cleaning ring 204 and the second cleaning ring 207 on the motor body 2 slide along the surface of the heat dissipation filter plate 201 on the vibration motor 203, so as to achieve the cleaning effect of scraping and wiping the heat dissipation filter plate 201, and at the same time control the working state of the electromagnet 215, so as to adjust the first cleaning ring 204 and the second cleaning ring 207 to cooperate with the shrink belt 217 to fit the surface of the heat dissipation filter plate 201, and achieve the effect of cleaning the inner diameter of the heat dissipation hole 206 on the heat dissipation filter plate 201 through the telescopic rod 209;

[0063] S3. Finally, the heat dissipation filter plate 201 rotates along the axis of the rotating ring 211 and the sliding ring 208. When the rotating ring 211 rotates, the cleaning knife 210 is used to clean the impurities and dust on the inner side of the second cleaning ring 207 so that it can be used next time, thereby preventing excessive accumulation of impurities on the inner wall of the second cleaning ring 207 from affecting its own cleaning effect.

[0064] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
