Description

Technical Field

[0001] The present invention relates to the technical field of high-speed maglev transportation, and particularly to a dust removal device for ultra-high-speed low-vacuum pipelines. Background Art

[0002] The ultra-high-speed low-vacuum pipeline combines aerospace technology and ground rail transit technology. It uses superconducting maglev technology to detach from the ground and eliminate friction, and uses an internal pipeline with a near-vacuum to greatly reduce air resistance, thereby enabling the ultra-high-speed operation of the rail train, which has the advantages of being faster, more convenient, safer, and economically controllable.

[0003] Although the inside of the pipeline is in a low-vacuum state, dust still inevitably appears inside the low-vacuum pipeline. The dust will occupy the space inside the pipeline, reduce the flow space of 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 inside the pipeline, further increasing the resistance. Moreover, the dust accumulation will cause the exhaust port of the jet pump to be blocked or change the axis line of the diffuser tube, affecting the pumping efficiency of the vacuum pump and resulting in a decrease in vacuum degree. Summary of the Invention

[0004] In order to overcome the disadvantages that the accumulation of dust in the ultra-high-speed low-vacuum pipeline will cause an increase in resistance and a decrease in the pipeline vacuum degree, the present invention provides a dust removal device for ultra-high-speed low-vacuum pipelines.

A power storage mechanism is arranged inside the first U-shaped frame 204.

[0021] As Figures 4-6 shown, the power storage mechanism includes a first flexible shaft 301. The first flexible shaft 301 is rotatably connected to the inner wall of the first U-shaped frame 204. A second transmission component is connected to the first flexible shaft 301. The second transmission component is composed of a third belt pulley, a fourth belt pulley, a second belt and a second rotating wheel. Among them, the third belt pulley is rotatably connected to the inner wall of the first U-shaped frame 204.

[0022] As Figure 4 、Figure 6 As shown in Figure 7 Figure 1, the outer wall of the first flexible shaft 301 is symmetrically and fixedly sleeved with a first conical wheel 401. The first conical wheel 401 is located above the first wire wheel 302. The inner walls of the first U-shaped frame 204 are symmetrically and fixedly connected with L-shaped plates 4011. One side of the L-shaped plate 4011 is rotatably connected with a second conical wheel 402. The first conical wheel 401 is in contact with the second conical wheel 402.

[0023] As Figure 5 shown in

[0024] As Figure 4 shown in

[0025] Figure 2, the top of the inner wall of the first U-shaped frame 204 is symmetrically and fixedly connected with telescopic rods 501. The telescopic ends of the two telescopic rods 501 are fixedly connected to the limiting frame 502. The limiting frame 502 is used in cooperation with the scraping plate 208 and is used to limit the positions of the two scraping plates 208. Figure 6 Figure 3, a wedge-shaped block 601 is fixedly connected to the outer wall of the second U-shaped frame 205. The wedge-shaped block 601 is used in cooperation with the limiting frame 502. When the wedge-shaped block 601 moves, it squeezes the limiting frame 502, causing the limiting frame 502 to lift upward.

[0026] As Figure 7As shown, a slide bar 801 is symmetrically and penetratingly slidably connected to the lower part of the rear side of the first U-shaped frame 204. A connecting plate 8011 is fixedly connected to the front end of the slide bar 801. The third wire wheel 405 is rotatably connected to the connecting plate 8011. An elastic telescopic rod 802 is arranged between the connecting plate 8011 and the L-shaped plate 4011. When the slide bar 801 moves, the second engaging disc 404 is no longer engaged with the first engaging disc 403.

[0027] As Figure 8 and Figure 9 shown, it further includes a sealing plate 901. Rectangular holes are symmetrically and penetratingly formed on both sides of the first U-shaped frame 204. Sealing plates 901 and sliding blocks 902 are symmetrically and vertically slidably connected to the inner wall of the first U-shaped frame 204. The two sealing 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 sealing plate 901. A protruding shaft is fixedly connected to one side of the sliding block 902. Vertical grooves are symmetrically and penetratingly formed on both sides of the first U-shaped frame 204. The protruding shaft of the sliding block 902 is clamped into the vertical groove and slides therein. Air guide pipes 903 are symmetrically fixedly connected to the inner wall of the first U-shaped frame 204, and rotating plates 904 are symmetrically hinged.

[0028] As Figure 8 shown, elastic limit blocks 1001 are symmetrically and horizontally slidably connected inside the first U-shaped frame 204. The horizontal angle of the lower inclined surface of the elastic limit block 1001 is greater than that of the upper inclined surface. The sealing plate 901 and the elastic limit block 1001 are used in cooperation.

[0029] As Figure 8 shown, inclined rods 1101 are symmetrically hinged to the rear side of the inner wall of the vacuum pipeline 1. The protruding shaft of the sliding block 902 and the inclined rod 1101 are used in cooperation. When the protruding shaft of the sliding block 902 contacts the inclined rod 1101, the sealing plate 901 is lifted upward. Sealing plates 1102 are symmetrically and horizontally slidably connected to the inner wall of the vacuum pipeline 1. A fourth compression spring is arranged between the sealing plate 1102 and the vacuum pipeline 1.

[0030] 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 inner wall top of the first U-shaped frame 204, the bottom of the sealing plate 901 is in contact with the inner wall bottom of the first U-shaped frame 204, and both rotating plates 904 are in a vertical state, forming a closed space between the first U-shaped frame 204 and the second U-shaped frame 205. The coil spring is in a released state, and the rear side of the sliding rod 801 abuts against the front side of the sealing plate 1102. When the maglev track in the vacuum pipeline 1 is started, the magnetic force generated by the maglev track generates a repulsive force on the magnet at the bottom of the first slider 203. The magnet drives the first slider 203 to lift upward. The first slider 203 drives the convex shaft thereon to lift upward, and the convex shaft drives the first slider 203 to slide obliquely upward along the inclined groove of the prefabricated frame 201. The first slider 203 presses against the front side inner wall of the sliding box 202, and the sliding box 202 slides forward along the prefabricated frame 201 under the force. The first compression spring is compressed. At this time, the two sliding boxes 202 drive the first U-shaped frame 204 to slide horizontally forward. The first U-shaped frame 204 drives the first meshing disc 403 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 contracts, and drives the third wire wheel 405 and the second meshing disc 404 to remain stationary relative to the vacuum pipeline 1 through the connecting plate 8011. The gap between the first meshing disc 403 and the second meshing disc 404 continues to shorten until the telescopic end of the elastic telescopic rod 802 is completely contracted. At this time, the first meshing disc 403 and the second meshing disc 404 mesh with each other. The L-shaped plate 4011 drives the sliding rod 801 forward through the elastic telescopic rod 802 and the connecting plate 8011. 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 presses against the bottom of the inclined rod 1101. The inclined rod 1101 rotates upward with the connection point of the vacuum pipeline 1 as the center under the force. Subsequently, the protruding shaft of the sliding block 902 passes over the inclined rod 1101 and no longer contacts it. After the inclined rod 1101 is released from the restriction, it rotates and resets. At the same time, the first U-shaped frame 204 drives the second U-shaped frame 205 to slide horizontally forward through the second compression spring, and drives the friction wheel 206 and the soft shaft brush 207 forward. The friction wheel 206 rotates counterclockwise with the connection point of the first U-shaped frame 204 as the center under the action of friction with the inner wall of the vacuum pipeline 1, and rubs against 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 should be noted that since the wheel shafts of the second rotating wheel and the third belt pulley are connected for one-way rotation, the second rotating wheel will not drive the third belt pulley to rotate. And when the second rotating wheel does not rotate, it restricts the third belt pulley from rotating. When the second rotating wheel rotates clockwise, it no longer restricts the third belt pulley, and the third belt pulley rotates, causing the second compression spring to push the second U-shaped frame 205 to move. The second U-shaped frame 205 exerts a forward force on the second wire wheel 303 through the support plate.The second wire wheel 303 pulls the wire rope thereon, causing the wire rope to be released from the first wire wheel 302. The first wire wheel 302 is stressed and drives the first flexible shaft 301 to rotate. The first flexible shaft 301 drives the fourth pulley in the second transmission assembly to rotate. The fourth pulley drives the third pulley to rotate through the second belt. At this time, the third pulley rotates synchronously with the second rotating wheel, enabling the first flexible shaft 301 to rotate smoothly until the second compression spring is completely released. The coil spring begins to contract and drives the second wire wheel 303 to rotate, causing the second wire wheel 303 to wind up the wire rope and pull the first wire wheel 302 to rotate until the coil spring is completely contracted and the second wire wheel 303 stops rotating. Consequently, the first wire wheel 302 and the first flexible shaft 301 also stop rotating. At this time, there is a gap between the front side of the first U-shaped frame 204 and the front side of the second U-shaped frame 205. Meanwhile, the first rotating wheel drives the first pulley to rotate clockwise. The first pulley drives the second pulley to rotate clockwise through the first belt. The second pulley drives the soft shaft brush 207 to rotate clockwise with the connection point of the first U-shaped frame 204 as the center. When the soft shaft brush 207 rotates, it sweeps off the dust adhering to the inner wall of the vacuum pipeline 1. Since the inside of the vacuum pipeline 1 is in a low vacuum state and there are only a small number of air molecules in the vacuum pipeline 1, the resistance exerted by the air on the dust is extremely small. After the dust is swept off, it directly falls onto the top surface of the second U-shaped frame 205 under the action of gravity. And because the first U-shaped frame 204 and the second U-shaped frame 205 move forward, some dust will fall onto 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 pipeline 1, thus completing the cleaning of the dust on the inner wall of the vacuum pipeline 1.,

[0031] When the maglev track of the vacuum pipeline 1 is closed, the maglev track no longer generates magnetic force and no longer exerts a repulsive force on the magnetic block at the bottom of the first slider 203. After the first slider 203 is released from the restriction, the sliding box 202 moves. The first compression spring releases and drives the sliding box 202 to slide back to its original position. The sliding box 202 drives the first slider 203 to slide backward. 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 flexible shaft brush 207 to move backward. The friction wheel 206 rotates clockwise with the connection point of the first U-shaped frame 204 as the center under the action of friction with the inner wall of the vacuum pipeline 1, and makes the second rotating wheel drive the third belt pulley to rotate counterclockwise by friction with the first rotating wheel in the first transmission assembly and the second rotating wheel in the second transmission assembly. It should be noted that since the wheel shafts of the first rotating wheel and the first belt pulley are connected for one-way rotation, the first rotating wheel will not drive the first belt pulley to rotate at this time, so that the flexible shaft brush 207 stops rotating. At this time, the third belt pulley drives the fourth belt pulley to rotate counterclockwise through the second belt. The fourth belt 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, it winds the steel wire rope on it. The steel wire rope drives the second wire wheel 303 to rotate. The steel wire rope on the second wire wheel 303 is gradually released. When the second wire wheel 303 rotates, the coil spring between the second wire wheel 303 and the support plate is stressed and contracts. 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 disc 404 to rotate through the first meshing disc 403. The second meshing disc 404 drives the third wire wheel 405 to rotate. At this time, the two third wire wheels 405 rotate simultaneously and wind the pull ropes on them. The pull ropes are stressed and pull the second sliders 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 scraping plates 208 contact the inner wall of the limiting frame 502. The limiting frame 502 limits the two scraping plates 208, and the scraping plates 208 are restricted and cannot move. The first tension spring between the second slider 407 and the corresponding scraping plate 208 is stressed and extends. Subsequently, the second slider 407 contacts and presses against the top of the corresponding contact plate 702. The contact plate 702 is stressed and descends, and exerts a pulling force 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 stressed and extend. The elastic telescopic shaft 7011 exerts a pulling force on the piston plate 703. Since the inside of the vacuum pipeline 1 is in a low vacuum state, only a small amount of air can enter the air extraction pump 701 at this time, so that the piston plate 703 slowly descends. Subsequently, 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. The sliding block 902 exerts a pulling force on the sealing plate 901 through the third tension spring. It should be noted thatDue to the angle characteristics of the lower inclined surface of the elastic limiting block 1001, the extrusion force of the elastic limiting block 1001 on the plugging plate 901 is greater than the pulling force of the third tension spring on the plugging plate 901. The sliding block 902 slides upward relative to the plugging plate 901, and the third tension spring is stretched. Subsequently, the rear side of the sliding rod 801 contacts and presses against the front side of the corresponding sealing plate 1102. It should be noted 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 sliding rod 801 through the connecting plate 8011, causing the sliding rod 801 to exert a thrust on the sealing plate 1102. The sealing plate 1102 slides backward under the force, and the fourth compression spring is compressed. After the sealing plate 1102 slides, it no longer plugs the sewage discharge hole of the vacuum pipeline 1. At this time, since the first U-shaped frame 204 and the two plugging plates 901 move backward, the outer wall of the first U-shaped frame 204 and the side wall of the plugging plate 901 plug the sewage discharge hole of the vacuum pipeline 1, thereby preventing external air from entering the vacuum pipeline 1 through the sewage discharge hole of the vacuum pipeline 1 until the fourth compression spring is completely compressed, the sealing plate 1102 stops moving and provides support for the sliding rod 801. The sliding rod 801 is restricted from moving, and the first U-shaped frame 204 continues to move backward. The sliding rod 801 drives the third wire wheel 405 and the second meshing disc 404 to stop moving through the connecting plate 8011. At this time, the first meshing disc 403 moves backward relative to the second meshing disc 404, and the telescopic end of the elastic telescopic rod 802 is stretched. At the same time, the coil spring contracts to the limit, making the second wire wheel 303 unable to rotate. The first wire wheel 302 continues to rotate and wind the steel wire rope. The steel wire rope exerts a pulling force on the second wire wheel 303. The second wire wheel 303 drives the second U-shaped frame 205 to move backward relative to the first U-shaped frame 204 through the support plate under the force, and the second compression spring is compressed. The second U-shaped frame 205 drives the wedge block 601 to move, causing the inclined surface of the wedge block 601 to press against the bottom of the limiting frame 502. The limiting frame 502 is lifted upward and drives the telescopic ends of the two telescopic rods 501 to contract until the top of the second U-shaped frame 205 fits against 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. After the limiting frame 502 is lifted, it crosses the top surfaces of the two scraping plates 208. After the scraping plates 208 are released from the restriction, they move. The first tension spring contracts and pulls the scraping plates 208. At this time, the two scraping plates 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, and the third compression spring is compressed. Thus, the two scraping plates 208 scrape the dust on the inner wall of the first U-shaped frame 204 to both sides. When the dust is scraped, it will not fly out of the closed space between the first U-shaped frame 204 and the second U-shaped frame 205. Subsequently, the third tension spring extends to the limit, and the pulling force of the third tension spring on the plugging plate 901 is greater than the extrusion force of the elastic limiting block 1001 on the plugging plate 901. The elastic limiting block 1001 is compressed and no longer contacts the top of the plugging plate 901. After the plugging plate 901 is released from the restriction, it moves.The contraction of the third tension spring drives the plugging plate 901 to lift and slide upward. After the plugging plate 901 slides, the closed space formed by the first U-shaped frame 204 and the second U-shaped frame 205 is communicated with the outside through the sewage discharge hole of the vacuum pipeline 1. The outside air enters the air guide pipe 903 and then enters the first U-shaped frame 204 through the air guide pipe 903, filling the first U-shaped frame 204 with air. It should be noted 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, and the air entering the first U-shaped frame 204 will not cause the dust to float upward. At this time, a part of the air enters the air extraction pump 701 through the intake valve 704. The fixed end of the elastic telescopic shaft 7011 descends and slides, driving the piston plate 703 to descend, so that the air extraction pump 701 stores air. At this time, the second U-shaped frame 205 continues to slide backward relative to the first U-shaped frame 204, and then the protruding shaft of the sliding block 902 contacts the horizontal plane of the inclined rod 1101, and the first meshing disc 403 no longer contacts the second meshing disc 404. After the second meshing disc 404 is released from the restriction, the third wire wheel 405 moves. The release of the third compression spring drives the scraper 208 to slide back to its original position. The scraper 208 pulls the second slider 407 to slide back to its original position through the first tension spring. 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 disc 404 to rotate back to its original position through the third wire wheel 405. After the second slider 407 returns to its original position, it no longer contacts the contact plate 702. After the contact plate 702 is released from the restriction, it moves. The contraction of the second tension spring drives the contact plate 702 to lift and return to its original position. 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 extraction pump 701, and the air enters the purging pipe 209 through the one-way valve. The purging 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 purging 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. The rotating plates 904 are forced to rotate around the connection of the first U-shaped frame 204. The dust is impacted by the air and discharged from the sewage discharge hole of the vacuum pipeline 1 through the gap between the rotating plates 904 and the first U-shaped frame 204. The purging pipe 209 can achieve the above effect without blowing out a large amount of air. Subsequently, the protruding shaft of the sliding block 902 crosses the rear end of the inclined rod 1101, and the sliding block 902 descends and slides under the influence of its own weight and the weight of the plugging plate 901. Subsequently, the bottom of the plugging plate 901 fits with the bottom of the first U-shaped frame 204, and the purging pipe 209 no longer blows out air. The two rotating plates 904 are no longer impacted by the air and rotate back to their original positions around the connection of the first U-shaped frame 204, thus completing the reset of the overall device and realizing the cleaning and discharge of the dust in the vacuum pipeline 1.,
