Description

Technical Field

[0001] The present invention relates to the technical field of high-speed magnetic levitation transportation, and in particular to an ultra-high-speed low-vacuum pipeline dust removal device. Background Art

[0002] The ultra-high-speed low-vacuum pipeline integrates aerospace technology and ground rail transportation technology. It uses superconducting magnetic levitation technology to break away from the ground and eliminate friction, and uses internal near-vacuum pipeline lines to greatly reduce air resistance, thereby realizing ultra-high-speed operation of rail trains. It has the advantages of being faster, more convenient, safer and more economical.

[0003] Although the inside of the pipeline is in a low vacuum state, dust will inevitably appear inside the low vacuum pipeline. The dust will occupy the space in the pipeline, reduce the flow space of the gas or fluid, and increase the flow resistance. When the dust accumulates to a certain extent, it will change the flow state of the gas or fluid in the pipeline, further increasing the resistance. The accumulation of dust will cause the exhaust port of the jet pump to be blocked or change the axial centerline of the diffuser tube, affecting the vacuum pump's extraction efficiency and causing a decrease in vacuum.

[0031] like Figure 5 As shown, telescopic rods 501 are symmetrically fixed to the top of the inner wall of the first U-shaped frame 204, and the telescopic ends of the two telescopic rods 501 are fixed to the limit frame 502. The limit frame 502 is used in conjunction with the scraper 208 to limit the position of the two scrapers 208.

[0032] like Figure 4 As shown, a wedge block 601 is fixedly connected to the outer wall of the second U-shaped frame 205. The wedge block 601 is used in conjunction with the limiting frame 502. When the wedge block 601 moves, it squeezes the limiting frame 502 to lift the limiting frame 502 upward.

[0033] like Figure 6 As shown, it also includes an air storage mechanism, which includes an air pump 701. The air pump 701 is symmetrically fixed to the lower part of the inner wall of the first U-shaped frame 204, and the bottom end of the air pump 701 is slidably connected to an elastic telescopic shaft 7011. The telescopic end of the elastic telescopic shaft 7011 is fixed to a contact plate 702, and the contact plate 702 is used in conjunction with the second slider 407. A second tension spring is arranged between the contact plate 702 and the bottom end of the air pump 701, and the fixed end of the elastic telescopic shaft 7011 is fixed to a piston plate 703. The piston plate 703 is slidably connected to the inner wall of the air pump 701.

[0034] like Figure 7As shown, the lower rear part of the first U-shaped frame 204 is symmetrically slidably connected with a slide rod 801, the front end of the slide rod 801 is fixed with a connecting plate 8011, the third pulley 405 is rotatably connected to the connecting plate 8011, and an elastic telescopic rod 802 is arranged between the connecting plate 8011 and the L-shaped plate 4011. When the slide rod 801 moves, the second engaging disk 404 is no longer engaged with the first engaging disk 403.

[0035] like Figure 8 and Figure 9 As shown, it also includes a blocking plate 901, and rectangular holes are symmetrically opened on both sides of the first U-shaped frame 204. The inner wall of the first U-shaped frame 204 is symmetrically and vertically slidably connected with a blocking plate 901 and a sliding block 902. The two blocking plates 901 are respectively arranged corresponding to the two rectangular holes of the first U-shaped frame 204. A third tension spring is arranged between the sliding block 902 and the blocking plate 901. A protruding shaft is fixed to one side of the sliding block 902, and vertical grooves are symmetrically opened on both sides of the first U-shaped frame 204. The protruding shaft of the sliding block 902 is stuck in the vertical groove and slides therein. The inner wall of the first U-shaped frame 204 is symmetrically fixed with an air guide tube 903, and is symmetrically hinged with a rotating plate 904.

[0036] like Figure 8 As shown, an elastic limit block 1001 is symmetrically and horizontally slidably connected in the first U-shaped frame 204 . The horizontal angle of the lower slope of the elastic limit block 1001 is greater than the horizontal angle of the upper slope. The blocking plate 901 is used in conjunction with the elastic limit block 1001 .

[0037] like Figure 8 As shown, the rear side of the inner wall of the vacuum pipe 1 is symmetrically hinged with an inclined rod 1101, and the protruding shaft of the sliding block 902 is used in conjunction with the inclined rod 1101. When the protruding shaft of the sliding block 902 contacts the inclined rod 1101, the sealing plate 901 is lifted upward, and the inner wall of the vacuum pipe 1 is symmetrically and horizontally slidably connected with a sealing plate 1102, and a fourth compression spring is arranged between the sealing plate 1102 and the vacuum pipe 1.

[0038] Initially, the first compression spring and the second compression spring are in a contracted state, the top of the second U-shaped frame 205 is in contact with the top of the inner wall of the first U-shaped frame 204, the bottom of the sealing plate 901 is in contact with the bottom of the inner wall of the first U-shaped frame 204, and the two rotating plates 904 are in a vertical state, so that a closed space is formed between the first U-shaped frame 204 and the second U-shaped frame 205, the coil spring is in a released state, the rear side of the slide bar 801 is against the front side of the sealing plate 1102, and when the magnetic levitation track in the vacuum pipe 1 is started, the magnetic force generated by the magnetic levitation track produces a repulsive force on the magnetic block at the bottom of the first slider 203, and the magnetic block is driven by the force to lift the first slider 203 upward, and the first slider 203 drives the convex shaft thereon to lift upward, and the convex shaft drives the first slider 203 along The inclined groove of the prefabricated frame 201 slides obliquely upward, and the first slider 203 squeezes the front side of the inner wall of the sliding box 202. The sliding box 202 is forced to slide forward along the prefabricated frame 201, and the first compression spring is forced to shrink. At this time, the two sliding boxes 202 drive the first U-shaped frame 204 to slide horizontally to the front side, and the first U-shaped frame 204 drives the first meshing disk 403 to move forward through the L-shaped plate 4011. The telescopic end of the elastic telescopic rod 802 between the connecting plate 8011 and the L-shaped plate 4011 gradually shrinks, and drives the third wire wheel 405 and the second meshing disk 404 to remain stationary relative to the vacuum pipe 1 through the connecting plate 8011. The gap between the first meshing disk 403 and the second meshing disk 404 continues to shorten until the elastic telescopic rod 802 is extended. The retracted end is fully retracted, at which time the first meshing disk 403 and the second meshing disk 404 are meshed with each other, and the L-shaped plate 4011 drives the sliding rod 801 to move forward through the elastic telescopic rod 802 and the connecting plate 8011, and the fourth compression spring is gradually released and drives the sealing plate 1102 to move forward synchronously with the sliding rod 801, and the protruding shaft of the sliding block 902 squeezes the bottom of the inclined rod 1101, and the inclined rod 1101 is forced to rotate upward with the connection point of the vacuum pipe 1 as the center of the circle, and then the protruding shaft of the sliding block 902 passes over the inclined rod 1101 and no longer contacts it, and the inclined rod 1101 rotates and resets after being freed from the restriction, and at the same time, the first U-shaped frame 204 drives the second U-shaped frame 205 to slide horizontally to the front side through the second compression spring, and drives the friction wheel 206 and the soft shaft The brush 207 moves forward, and the friction wheel 206 rotates counterclockwise with the connection point of the first U-shaped frame 204 as the center of the circle under the action of friction with the inner wall of the vacuum pipe 1, and rubs with the first rotating wheel in the first transmission assembly and the second rotating wheel in the second transmission assembly. At this time, the second rotating wheel rotates clockwise. It is worth noting that since the second rotating wheel and the axle of the third pulley are connected in a one-way rotation manner, the second rotating wheel will not drive the third pulley to rotate, and when the second rotating wheel does not rotate, the third pulley is restricted from rotating. When the second rotating wheel rotates clockwise, it no longer restricts the third pulley. The third pulley rotates, causing the second compression spring to push the second U-shaped frame 205 to move. The second U-shaped frame 205 applies a force to the second wire pulley 303 toward the front side through the support plate.After the first gear 302 is in the state of being rotated, the first gear 302 is in the state of being rotated, and the first gear 302 is in the state of being rotated. At the same time, the first rotating wheel drives the first pulley to rotate clockwise, and the first pulley drives the second pulley to rotate clockwise through the first belt, and the second pulley drives the flexible shaft brush 207 to rotate clockwise with the connection point of the first U-shaped frame 204 as the center of the circle. When the flexible shaft brush 207 rotates, it sweeps off the dust attached to the inner wall of the vacuum duct 1. Since the interior of the vacuum duct 1 is in a low vacuum state, there are only a small number of air molecules in the vacuum duct 1, and the resistance exerted by the air on the dust is extremely small. After the dust is swept off, the dust falls directly on the top surface of the second U-shaped frame 205 under the action of gravity. Moreover, since the first U-shaped frame 204 and the second U-shaped frame 205 move forward, some dust will fall on the inner wall of the first U-shaped frame 204 until the second U-shaped frame 205 moves to the front end of the vacuum duct 1, thereby completing the cleaning of the dust on the inner wall of the vacuum duct 1.

[0039] When the magnetic levitation track of the vacuum pipe 1 is closed, the magnetic levitation track no longer generates magnetic force and no longer applies repulsive force to the magnetic block at the bottom of the first slider 203. After the first slider 203 is freed from the restriction, the sliding box 202 is movable, and the first compression spring is released to drive the sliding box 202 to slide back. The sliding box 202 drives the first slider 203 to slide backward, and the convex shaft of the first slider 203 slides obliquely downward along the inclined groove of the prefabricated frame 201. At this time, the two sliding boxes 202 drive the first U-shaped frame 204 to slide horizontally backward. The first U-shaped frame 204 drives the second U-shaped frame 205 to slide horizontally backward through the second compression spring, and drives the friction wheel 206 and the soft shaft brush 207 to move backward. The friction wheel 206 rubs against the inner wall of the vacuum pipe 1 The first U-shaped frame 204 rotates clockwise with the connection point as the center, and rubs with the first rotating wheel in the first transmission assembly and the second rotating wheel in the second transmission assembly, so that the second rotating wheel drives the third pulley to rotate counterclockwise. It is worth noting that since the first rotating wheel and the wheel axle of the first pulley are unidirectionally rotated, the first rotating wheel will not drive the first pulley to rotate, so that the soft shaft brush 207 no longer rotates. At this time, the third pulley drives the fourth pulley to rotate counterclockwise through the second belt, and the fourth pulley drives the first wire wheel 302 and the first conical wheel 401 to rotate through the first flexible shaft 301. When the first wire wheel 302 rotates, the wire rope thereon is wound up, and the wire rope drives the second wire wheel 303 to rotate, and the wire rope on the second wire wheel 303 is gradually released. When the second spool 303 rotates, the coil spring between the second spool 303 and the support plate is forced to shrink. At the same time, the first conical wheel 401 rubs against the second conical wheel 402. The second conical wheel 402 drives the second meshing disk 404 to rotate through the first meshing disk 403. The second meshing disk 404 drives the third spool 405 to rotate. At this time, the two third spools 405 rotate at the same time and reel in the pull ropes thereon. The pull rope is pulled by force to pull the second slider 407, so that the two second sliders 407 slide away from each other along the inner wall of the first U-shaped frame 204. At this time, the two scrapers 208 contact the inner wall of the limit frame 502. The limit frame 502 limits the two scrapers 208. The scrapers 208 are restricted and cannot move. The second slider 407 is aligned with the corresponding scraper 208. The first tension spring between them is extended under force, and then the second slider 407 contacts and squeezes the top of the corresponding contact plate 702, and the contact plate 702 is forced to fall downward and exerts tension on the telescopic end of the elastic telescopic shaft 7011. The telescopic end of the elastic telescopic shaft 7011 and the second tension spring are extended under force, and the elastic telescopic shaft 7011 exerts tension on the piston plate 703. Since the vacuum pipe 1 is in a low vacuum state at this time, only a small amount of air can enter the air pump 701, causing the piston plate 703 to slowly fall downward, and then the protruding shaft of the sliding block 902 contacts the inclined rod 1101 on the same side, and slides along the inclined surface of the inclined rod 1101 to drive the sliding block 902 to lift upward, and the sliding block 902 exerts tension on the blocking plate 901 through the third tension spring. It is worth noting thatDue to the angle characteristics of the lower inclined surface of the elastic limit block 1001, the squeezing force of the elastic limit block 1001 on the sealing plate 901 is greater than the pulling force of the third tension spring on the sealing plate 901, and the sliding block 902 slides upward relative to the sealing plate 901, and the third tension spring is extended under the force, and then the rear side of the slide rod 801 contacts and squeezes the front side of the corresponding sealing plate 1102. It is worth noting that the elastic force of the elastic telescopic rod 802 is greater than the elastic force of the fourth compression spring. At this time, the elastic telescopic rod 802 provides sufficient pulling force to the slide rod 801 through the connecting plate 8011, so that the slide rod 801 applies a thrust to the sealing plate 1102, and the sealing plate 1102 is forced to slide toward the rear side, and the fourth compression spring is forced to contract. After sliding, the sealing plate 1102 no longer contacts the sewage hole of the vacuum pipe 1. Blockage. At this time, since the first U-shaped frame 204 and the two blocking plates 901 move toward the rear side, the outer wall of the first U-shaped frame 204 and the side wall of the blocking plate 901 block the drain hole of the vacuum pipe 1, thereby preventing external air from entering the vacuum pipe 1 through the drain hole of the vacuum pipe 1, until the fourth compression spring is completely contracted, the sealing plate 1102 no longer moves, and provides support for the sliding rod 801. The sliding rod 801 is restricted and cannot move, and the first U-shaped frame 204 continues to move toward the rear side. The sliding rod 801 drives the third wire wheel 405 and the second meshing disk 404 to stop moving through the connecting plate 8011. At this time, the first meshing disk 403 moves toward the rear side relative to the second meshing disk 404, and the telescopic end of the elastic telescopic rod 802 is forced to extend, and the winding spring is retracted. The second U-shaped frame 205 is forced to move backward relative to the first U-shaped frame 204 through the support plate, and the second compression spring is forced to contract, and the second U-shaped frame 205 drives the wedge block 601 to move, so that the inclined surface of the wedge block 601 is squeezed against the bottom of the limiting frame 502, and the limiting frame 502 is forced to lift upward and drive the telescopic ends of the two telescopic rods 501 to contract until the top of the second U-shaped frame 205 is in contact with the top of the inner wall of the first U-shaped frame 204. At this time, a closed space is formed between the first U-shaped frame 204 and the second U-shaped frame 205, and the limiting frame 502 is lifted and passes over the two The top surface of the scraper 208, the scraper 208 moves after being freed from the restriction, the first tension spring contracts and pulls the scraper 208, at this time the two scrapers 208 slide away from each other along the outer wall of the U-shaped column 406 and the inner wall of the first U-shaped frame 204, the third compression spring contracts under the force, thereby causing the two scrapers 208 to scrape the dust on the inner wall of the first U-shaped frame 204 to both sides, and the dust will not fly out of the closed space between the first U-shaped frame 204 and the second U-shaped frame 205 when being scraped. Then the third tension spring extends to its limit, and the pulling force of the third tension spring on the blocking plate 901 is greater than the squeezing force of the elastic limit block 1001 on the blocking plate 901. The elastic limit block 1001 is forced to contract and no longer contacts the top of the blocking plate 901, and the blocking plate 901 moves after being freed from the restriction.The third tension spring contracts and drives the blocking plate 901 to lift and slide upward. After the blocking plate 901 slides, the closed space formed by the first U-shaped frame 204 and the second U-shaped frame 205 is connected to the outside through the drain hole of the vacuum pipe 1. The outside air enters the air guide pipe 903 and enters the first U-shaped frame 204 through the air guide pipe 903, so that the first U-shaped frame 204 is filled with air. It is worth noting that at this time, the dust is located at the bottom of both sides of the inner wall of the first U-shaped frame 204. When the air enters the first U-shaped frame 204, the dust will not float upward. At this time, a part of the air enters the air pump 701 through the air inlet valve 704, and the fixed end of the elastic telescopic shaft 7011 slides down, driving the piston plate 703 to move downward. The second U-shaped frame 205 continues to slide backward relative to the first U-shaped frame 204, so that the protruding axis of the sliding block 902 contacts the horizontal surface of the inclined rod 1101, and the first meshing disk 403 no longer contacts the second meshing disk 404. After the second meshing disk 404 is released from the restriction, the third wire wheel 405 is activated, and the third compression spring is released to drive the scraper 208 to slide back to its original position. The scraper 208 is pulled back to its original position by the first tension spring to pull the second slider 407. The second slider 407 pulls the pull rope, and the pull rope is released from the third wire wheel 405 and drives the second meshing disk 404 to rotate and reset through the third wire wheel 405. After the second slider 407 is reset, it is no longer in contact with the contact plate 702 contacts, the contact plate 702 moves after being freed from the restriction, the second tension spring contracts and drives the contact plate 702 to lift and reset, the contact plate 702 drives the piston plate 703 to lift upward through the elastic telescopic shaft 7011, the piston plate 703 squeezes the air in the air pump 701, and the air enters the purge pipe 209 through the one-way valve, and the purge pipe 209 blows out air to purge the dust on the first U-shaped frame 204 and the second U-shaped frame 205. The air blown out by the purge pipe 209 flows along the inner wall of the first U-shaped frame 204 to the bottom of both sides of the inner wall of the first U-shaped frame 204, and impacts the side where the two rotating plates 904 are close to each other, and the rotating plate 904 is forced to rotate with the connection point of the first U-shaped frame 204 as the center. The dust is impacted by the air and discharged from the drain hole of the vacuum duct 1 through the gap between the rotating plate 904 and the first U-shaped frame 204. The purge pipe 209 does not need to blow out a large amount of air to achieve the above effect. Then, the protruding axis of the sliding block 902 passes over the rear end of the inclined rod 1101. The sliding block 902 slides downward under the influence of its own weight and the weight of the blocking plate 901. Then, the bottom of the blocking plate 901 is in contact with the bottom of the first U-shaped frame 204. The purge pipe 209 no longer blows air. The two rotating plates 904 are no longer impacted by the air and rotate to reset with the connection point of the first U-shaped frame 204 as the center. This completes the reset of the entire device and achieves the cleaning and discharge of dust in the vacuum duct 1.
