Description

Technical Field

[0001] This invention relates to the field of high-speed train exterior cleaning, and more specifically, to a mobile intelligent high-speed train exterior washing device. Background Technology

[0002] Currently, there are two main methods for cleaning the exterior of high-speed trains in my country: automatic pre-depot cleaning and manual cleaning inside the depot. The disadvantage of automatic pre-depot cleaning is that the cleaning quality cannot be guaranteed while the train is passing through, and stubborn stains may remain on the surface after cleaning, often requiring manual re-cleaning. Manual cleaning inside the depot requires more than 20 people and over 40 minutes to clean a single train, resulting in significant problems such as a large number of workers, difficulty in recruitment and management, heavy workload, low efficiency, lack of standardized cleaning quality, and waste of cleaning agents and water.

[0035] The workflow of the car wash device proposed in this embodiment is as follows:

[0036] The mobile trolley 1 drives the car wash machine 2 to move synchronously. The laser navigation radar can operate according to the scanned designated path, and the obstacle avoidance radar can avoid obstacles when the mobile trolley 1 is moving. Under the action of the brush frame 304, the top brush assembly 301, the vertical brush assembly 302 and the skirt brush assembly 303 can clean the vehicle. The wastewater after cleaning flows into the inside of the recycling tank 4 and is recycled by the recycling tank 4. When cleaning the vehicle, the nozzle 504 can spray three forms of liquid: water, water with cleaning solution and cleaning solution foam.

[0037] The water pump delivers water into the telescopic pipe 501, and the water can be sprayed directly from the nozzle 504 through the telescopic pipe 501. When the valve 503 is opened, the cleaning agent enters the telescopic pipe 501 through the liquid addition pipe 502 and merges with the water flow. The water flow drives the drive blade 603 to rotate. The drive blade 603 drives the mixing blade 602 to rotate through the straight shaft 601. When the mixing blade 602 rotates, it can mix the water and the cleaning liquid together. The mixed cleaning liquid and water can be sprayed out together through the nozzle 504.

[0038] When cleaning agent foam needs to be sprayed, the cylinder 801 is connected to an external power source. The cylinder 801 drives the rack 802 to move up and down. Since the rack 802 and the gear ring 803 are meshed, the rack 802 can drive the gear ring 803 to rotate back and forth. Since the gear ring 803 and the linkage 809 are fixedly connected, the gear ring 803 can drive the linkage 809 to rotate back and forth. When the linkage 809 rotates back and forth, it can drive the adjusting plate 708 to swing back and forth around the axis of the water outlet pipe 701. When the adjusting plate 708 swings, it intersects with the water inlet 707 opened on the first sealing member 706, so that the water can flow through the water inlet 707 to the bottom of the water outlet pipe 701.

[0039] It should be noted that in the initial state, the adjusting plate 708 completely blocks the water inlet 707, and the water flows through and out of the inside of the water outlet pipe 701. When it is necessary to switch to the foam spraying state, the cylinder 801 drives the rack 802 to move downward, and the rack 802 drives the elastic telescopic member 908 to move synchronously. The rack 802 and the elastic telescopic member 908 descend synchronously. When the rack 802 descends to the first stage, the rack 802 drives the second baffle 909 to move synchronously through the elastic telescopic member 908. The second baffle 909 covers the opening of the water outlet pipe 701. When the rack 802 descends to the second stage, the rack 802 and the toothed ring 803 engage, and the elastic telescopic member 908 can maintain the second baffle 909 covering the opening of the water outlet pipe 701.

[0040] When the water flows below the outlet pipe 701, the large-pore sponge 704 absorbs the mixed liquid. It's important to note that when the water flows into the telescopic pipe 501, because the telescopic pipe 501 is horizontally positioned, the water flow is relatively small. The lower half of the large-pore sponge 704 is submerged in water, while the upper half extends above the liquid surface. Simultaneously, the linkage 809 drives the toothed gear 804 to move synchronously. As the toothed gear 804 moves, it contacts the vertical rod 807 and pushes the vertical rod 807 downwards. At this time, the vertical rod 807 moves outwards within the limiting member 805, pushing the primary filter plate 808 to absorb the large-pore... When the sponge 704 is squeezed, and the vertical rod 807 moves to the position between the two sets of teeth 804, the first spring 806 pulls the vertical rod 807 upward under the elastic force, so that the first-stage filter plate 808 can move away from the large-pore sponge 704. Through the reciprocating rotation of the linkage 809, the reciprocating lifting and lowering of the first-stage filter plate 808 is realized, so as to repeatedly press and release the large-pore sponge 704. Since the lower half of the large-pore sponge 704 is immersed in the mixed liquid and the upper half of the large-pore sponge 704 extends out of the mixed liquid, the upper half of the large-pore sponge 704 is filled with air.

[0041] During the pressing process of the large-pore sponge 704, the air inside flows upward and is discharged from the large-pore sponge 704, or flows downward. Because there are many small and interconnected pores in the sponge, the downward-flowing air and the flowing liquid mixture are constantly in contact and mixed with each other during the pressing process of the large-pore sponge 704, so as to achieve the purpose of generating bubbles. As the large-pore sponge 704 is pressed to its limit, the bubbles generated inside are discharged from the large-pore sponge 704. Since the density of the bubbles is less than that of the liquid mixture, the bubbles will float on the liquid mixture and continuously disperse and fill the primary foaming chamber.

[0042] As the primary filter plate 808 rises, the large-pore sponge 704 returns to its original shape. The lower half of the large-pore sponge 704 reabsorbs the mixed liquid, while the upper half absorbs air and some bubbles. As the large-pore sponge 704 is continuously pressed and restored, the purpose of rapidly generating bubbles is achieved.

[0043] At this point, the bubbles are relatively large and are partially mixed with the liquid.

[0044] This allows the large-pore sponge 704 to reabsorb water and detergent, and by repeatedly performing the above actions, the large-pore sponge 704 can squeeze water and detergent into detergent foam.

[0045] While the linkage 809 reciprocates, the linkage 809 drives the two primary partition plates 702 to swing back and forth around the water outlet pipe 701. When one primary partition plate 702 swings up, the other primary partition plate 702 swings down. The swinging primary partition plate 702 can squeeze the small-pore sponge 705, and the swinging primary partition plate 702 drives the small-pore sponge 705 to return to its original state.

[0046] During the downward swing of the primary partition plate 702, the push block 904 contacts the first baffle 901. The push block 904 pushes the first baffle 901 to rotate around the hinge axis 902, thereby opening the first baffle 901. At this time, since the primary foaming chamber is filled with bubbles, as the primary partition plate 702 continues to swing downward, the bubbles can enter the secondary foaming chamber. Moreover, when the primary partition plate 702 swings downward, the corresponding small-pore sponge 705 inside it is in the recovery action, so the small-pore sponge 705 can suck in the bubbles.

[0047] After the primary separator 702 swings down, it swings up again, pressing the small-pore sponge 705. At this time, some air bubbles will be discharged from the secondary foaming chamber. As it disengages from the pusher block 904, the first baffle 901 closes, thus closing the secondary foaming chamber. After the secondary foaming chamber is closed, the electric push rod 905 pushes the second seal 906 away from the secondary filter plate 907, connecting the secondary foaming chamber and the foam outlet chamber. As the primary separator 702 continues to swing up, the small-pore sponge 705 is continuously compressed. At this time, due to the small-pore sponge 705... Most of the absorbed bubbles gather in the lower half, while the upper half of the small-pore sponge 705 contains air. When it is squeezed, the bubbles inside it flow upwards again with the air inside the small-pore sponge 705. Bubbles with higher water content will come into contact with the air again and generate bubbles again. Moreover, larger bubbles will be broken down into smaller bubbles. As the small-pore sponge 705 is squeezed, these fine and dense bubbles will be discharged into the foam outlet chamber, which will then expel the foam.

[0048] Through the above steps, the mixture is first continuously mixed and contacted with air to create bubbles with a high water content and large volume. Then, the bubbles are mixed with air again to divide their volume, thereby achieving the purpose of creating fine and dense foam.

[0049] The foam extruded from the large-pore sponge 704 can be absorbed by the small-pore sponge 705. As the small-pore sponge 705 moves from the primary separator 702 towards the secondary separator 703, the primary separator 702 and the secondary separator 703 compress the small-pore sponge 705. Simultaneously, the electric push rod 905 pushes the second seal 906 away from the secondary filter plate 907, allowing the foam extruded from the small-pore sponge 705 to pass through the secondary filter plate 907. Between the secondary separator 703 and the telescopic tube 501, when the primary separator 702 moves away from the secondary separator 703, air can enter the interior of the telescopic tube 501 through the pressure valve. At the same time, the electric push rod 905 drives the second seal 906 to reset, and the second seal 906 blocks the secondary filter plate 907 again. The two small-pore sponges 705 continuously repeat the above actions, causing the foam between the secondary separator 703 and the telescopic tube 501 to continuously increase, thereby squeezing the foam out of the interior of the telescopic tube 501.

[0050] Through the above actions, the present invention can automatically clean vehicles before they enter the depot, thereby improving the quality and efficiency of cleaning the exterior of the EMU and reducing labor intensity.
