Description

Technical Field

[0001] The present invention relates to the technical field of car washers, and in particular to a tunnel car washer. Background Art

[0002] A tunnel car wash is a type of automated car wash that uses a series of automated mechanical devices and equipment to clean the exterior of a vehicle. The process typically involves the vehicle passing through a "tunnel"-shaped car wash system. During this process, the vehicle simply moves slowly through the wash without manual operation.

[0003] Existing tunnel car washers include a flushing system, a scrubbing system, and a drying system, wherein the scrubbing system uses a brush or roller to rotate and scrub the surface of the vehicle to remove stubborn stains. During the scrubbing process, traditional tunnel car washers usually adopt a mobile cleaning method, that is, the car is slowly pushed through the brush or roller by a conveyor belt. However, due to the different sizes, heights, and surface structures of each car, it is difficult for the brush or roller to completely fit the surface of the car during the mobile scrubbing process, which will cause the brush head to exert different pressures on different parts of the car surface during scrubbing; for some car surfaces that are far away from the brush head, the brush head cannot achieve complete contact, which may cause incomplete cleaning for stubborn stains on some car body surfaces; for some surfaces that are too close to the brush head, the friction of the brush head on its surface may be too great, causing scratches or damage to the surface paint;

[0004] Furthermore, existing scrubbing systems are typically equipped with brush heads of a single hardness. In addition to metal, a car's exterior surfaces also include glass and plastic. This may result in the brush head's hardness not being suitable for cleaning all materials. For some softer plastics, the brush head may abrade the surface, causing scratches or discoloration. Furthermore, for hard and smooth glass, the brush head may not be cleaned thoroughly enough, leaving water stains or smudges.

[0005] Therefore, it is necessary to invent a tunnel car washing machine. Summary of the Invention

DETAILED DESCRIPTION

[0036] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0037] Example 1, as Figure 1 - Figure 7As shown, a tunnel car washing machine in an embodiment of the first aspect of the present invention includes a tunnel shell 11, the tunnel shell 11 is a circular arch structure, a tunnel inner wall 12 is fixedly installed on the inner side of the tunnel shell 11, and a plurality of hexagonal sleeves 21 are arranged and installed on the outer side of the tunnel inner wall 12. The hexagonal sleeves 21 are arranged between the outer side of the tunnel inner wall 12 and the inner wall of the tunnel shell 11. A rear end plate 26 is fixedly installed on one end of the hexagonal sleeve 21 close to the tunnel shell 11, and a front end sleeve is fixedly installed on the other end of the hexagonal sleeve 21 close to the tunnel inner wall 12. 22, the front end sleeve 22 passes through the inner wall of the tunnel 12, and a spray water pipe 27 is fixedly installed on the inner wall of the front end sleeve 22. The spray water pipe 27 is used to flush water to the surface of the vehicle body. The end of the front end sleeve 22 close to the hexagonal sleeve 21 is retracted inward and fixedly connected to the hexagonal inner tube 23. The upper and lower sides of the hexagonal inner tube 23 are fixedly installed with a probe cover 31. A first base 32 is provided in the probe cover 31 on the upper side of the hexagonal inner tube 23. A ranging probe 33 is installed at the front end of the first base 32. The probe cover 31 on the lower side of the hexagonal inner tube 23 is fixed with a probe cover 31. A second base 34 is provided, and an ultrasonic hardness probe 35 is installed at the front end of the second base 34. One end of the hexagonal inner tube 23 away from the front sleeve 22 is fixedly connected to the front partition 24. A rear partition 25 is provided on the side of the front partition 24 away from the hexagonal inner tube 23. Three brush head covers 50 are slidably installed between the front partition 24 and the rear partition 25. The three brush head covers 50 pass through the three sides of the hexagonal sleeve 21 respectively. A third base 52 is provided in the brush head cover 50. A folding brush head is installed at the front end of the third base 52. The probe cover 31 A pushing structure is installed on the inner wall of the brush head cover shell 50, and the pushing structure is used to push the first base 32 or the second base 34 into the hexagonal inner tube 23. The pushing structure is also used to push the third base 52 to the middle of the front partition 24 and the rear partition 25. A magnetic push rod is fixedly installed between the rear partition 25 and the rear end plate 26. The magnetic push rod is used to magnetically connect the first base 32, the second base 34 or the third base 52. The magnetic push rod is also used to push the first base 32, the second base 34 or the third base 52 to the outside of the front sleeve 22.

[0038] In the above embodiment, it should be noted that each hexagonal sleeve 21 and its internal structure are independent entities, and each hexagonal sleeve 21 and its internal structure on the tunnel inner wall 12 operate independently. The front sleeve 22 is a trumpet-shaped structure. The distance measuring probe 33 is a pressure sensor probe. When the distance measuring probe 33 contacts the surface of the vehicle body, it reacts quickly and controls the magnetic push rod to stop, so that the magnetic push rod can measure the distance to the vehicle body surface. The ultrasonic hardness probe 35 measures the hardness by sending high-frequency sound waves to the surface of the object and analyzing the reflection of the sound waves. The hardness of different materials will affect the propagation speed and reflection intensity of the sound waves. Therefore, it can be used to distinguish between metal, plastic and glass parts on the vehicle body. According to the specific hardness of the vehicle body surface measured by the ultrasonic hardness probe 35, the folding brush head in the different brush head housings 50 is selected. The surface bristles of the folding brush heads in different brush head housings 50 have different hardness. The folding brush head with harder bristles is used to brush the glass surface, the folding brush head with moderate bristle hardness is used to brush the paint surface of the metal parts of the vehicle body, and the folding brush head with softer bristles is used to brush plastic parts.

[0039] The vehicle to be washed is parked in the tunnel shell 11, and the first base 32 is pushed into the hexagonal inner tube 23 by activating the pushing structure in the probe cover 31 on the upper side of the hexagonal inner tube 23. Then, the magnetic push rod is activated to drive the first base 32 to extend out of the hexagonal sleeve 21. The first base 32 continues to extend until the ranging probe 33 touches the surface of the car. At this time, the magnetic push rods in each hexagonal sleeve 21 record the current extension distance, and then the magnetic push rod drives the first base 32 to retract into the hexagonal inner tube 23. At the same time, the pushing structure pushes the first base 32 into the hexagonal inner tube 23. The base 32 is retracted to the probe cover 31 on the upper side of the hexagonal inner tube 23; then the pushing structure in the probe cover 31 on the lower side of the hexagonal inner tube 23 is activated to push the second base 34 into the hexagonal inner tube 23, and then the magnetic push rod is activated to drive the second base 34 to extend to the recorded distance, so that the ultrasonic hardness probe 35 contacts the car surface. At this time, the ultrasonic hardness probe 35 corresponding to each hexagonal sleeve 21 measures and records the material hardness of the current contact surface, and then the magnetic push rod drives the second base 34 to retract to the hexagonal inner tube 23, and at the same time, the pushing structure recycles the second base 34 to the probe cover 31 on the lower side of the hexagonal inner tube 23; starts the spray water pipe 27 to spray water or cleaning liquid on the surface of the vehicle body, and then selects to start the pushing structure in the corresponding brush head cover 50 according to the material hardness measured by each ultrasonic hardness probe 35, and pushes the corresponding third base 52 into the middle of the hexagonal sleeve 21. The bristles of the folding brush heads connected to the front ends of different third bases 52 are different in hardness. Then, the magnetic push rod is started again to drive the corresponding third base 52 to extend to the recorded distance, unfold the corresponding folding brush head and make the folding brush head fit the surface of the vehicle body, and finally start the folding brush head to brush various parts of the vehicle body surface in a targeted manner; so as to achieve the effect of using a static vehicle body and cooperating with the folding brush head to fit the surface of the car body for brushing, so that the brushing pressure on various parts of the car surface is consistent, and at the same time, brush heads of different hardness are selected for brushing according to the different materials of the car body, which can thoroughly clean stubborn stains while avoiding scratching the surface of the car body, thereby greatly improving the cleaning efficiency and cleaning quality.
