The N pieces of wiping cloths 33 are partially overlapped between the adjacent wiping cloths 33 in a natural suspension state.

Hereinafter, the water removal system of this embodiment will be additionally described in more detail.

Taking the gantry type water removing system running on the overhead rail of fig. 1 as an example, during the wiping operation, the motion of the moving frame body 13 relative to the automobile is consistent with the longitudinal direction of the automobile body, the back-and-forth swing in the following is the back-and-forth reciprocating motion of the wiping unit in the longitudinal direction (length direction) of the automobile body, and the left-and-right swing refers to the back-and-forth reciprocating motion of the sleeve 314, the connecting sheet 32 and the wiping cloth 33 which are connected with the sleeve, in the transverse cross section of the automobile body under the action of the pulling device. The rotation directions are both the directions in which the observer stands on the passenger seat side and faces the vehicle body side, and in this structure, the forward rotation of the rotating shaft 2 is the clockwise direction of the observer angle, and the reverse rotation is the counterclockwise direction.

The car in figure 1 is driven out of the car wash in a reverse mode, the floor-standing fan 8 is mounted at the door of the car wash at one end of the car tail, and the fan outlet 81 is slightly deviated towards the inside of the car wash towards the car body.

In this embodiment, the swinging device and the sleeve of the drying unit are mounted on the same moving frame body 13, and are powered by the rotating shaft driving device 21 of the rotating shaft 2. The rotating shaft releases the wiping cloth, the wiping unit swings back and forth, and the rotating shaft rotates anticlockwise when the wiping cloth swings left and right; the rotating shaft is clockwise rotated when the wiping cloth is wound around the rotating shaft, the rotating shaft soaks the wiping cloth and the wiping unit is dewatered and dried.

The specific cleaning process is as follows:

when the automobile drives into the car washing room, the automobile is stationary. Firstly, the automobile body 4 is sprayed with detergent, washed by high-pressure water and the like to remove various dirt on the automobile body 4, and then the wiping device of the invention carries out wiping and air drying operations.

Before the wiping operation, whether the wetting operation needs to be carried out on the wiping unit is determined according to the interval time of the previous automobile operation. For example, in the morning of summer, after a night stop, the wiping cloth 33 will be excessively dehydrated and too dry to effectively adhere to the surface of the vehicle body 4, which will affect the wiping water absorption effect, so that the clear water system is required to introduce clear water into the hollow part of the rotating shaft 2, and simultaneously the rotating shaft 2 is driven to rotate clockwise at a proper speed, so as to ensure that the clear water quickly, uniformly and moderately infiltrates the wiping cloth 33 and enters the preparation state of the wiping operation. At this time, the swing device and the pulling device are both separated from the rotating shaft 2.

Then, the rotating shaft 2 is rotated counterclockwise, and the wiping cloth 33 is released to be in a hanging state. When the wiping cloth 33 is released to the proper position, the first pawl return electromagnet 59 is actuated, and the first pawl 53 is disengaged from the first magnet 56, attracted by the second magnet 57, and enters an operating state.

Next, the car will be wiped in such a manner that the wiping cloth 33 swings back and forth. On the whole, the movable frame body 13 moves from the head to the tail of the vehicle; meanwhile, the rotating shaft driving device 21 drives the rotating shaft 2 to rotate counterclockwise, the first ratchet 51 fixed on the rotating shaft 2 is engaged with the first pawl 53 by the ratchet thereof, the cam 52 is driven to rotate counterclockwise, and the shift lever 5 fixed on the cam 52 moves along with the cam, thereby lifting the wiping cloth 33. As the cam 52 rotates through a certain angle, the first pawl 53 will meet the first stopper 58, thereby triggering the first pawl 53 to rotate, disengage from the ratchet teeth of the first ratchet 51, and be attracted by the first magnet 56. At this time, the cam 52, which is out of power, returns to the initial position by the gravity of the first return spring 55 and the wiper 33. In this position the first pawl reset electromagnet 59 remains in its original position and will again actuate the first pawl 53 to disengage the first magnet 56 and be attracted to the second magnet 57 into the 2 nd round operating condition. Reciprocating in this manner, the wiping cloth 33 continuously oscillates back and forth by the continuous rotation of the rotating shaft 2.

In the wiping process, the air blowing devices 7 on the left side and the right side of the frame body 13 are moved, air blowing openings of the air blowing devices are aligned with the middle lower part of the side face of the vehicle body, the wiping cloth 33 on the lower part is urged to be in contact with the lower hem of the side face of the vehicle body by air pressure, and the problem of poor contact caused by inward inclination of the lower hem of the vehicle body is solved.

During this wiping process, the lower middle portion of the wiping cloth 33 is in contact with the vehicle body 4. In the contact process, as the wiping cloth 33 falls down from a certain height, a certain force is formed for beating the surface of the vehicle body 4, which is beneficial to further decontamination or polishing, and has water removal and cleaning effects. Due to the dragging of the moving frame body 13, the wiping cloth 33 has certain dragging wiping with the vehicle body surface 4. The wiping effect is ideal under various acting forces.

After the wiping of the wiping unit in the front-rear swinging manner is completed, the first pawl resetting electromagnet 59 is restored to the initial state, so that the first pawl 53 is always attracted by the first magnet 56, and the swinging device is not linked with the rotating shaft 2 any more. At this time, the hanger 31 of the drying unit is in a vertically suspended state by the gravity of the connecting sheet 32 and the drying cloth 33.

Then, the third return electromagnet is operated, and the third pawl 63 is disengaged from the fifth magnet 66, attracted by the sixth magnet 67, and brought into an operating state. At this time, the rotating shaft 2 continues to rotate counterclockwise continuously, and the wiping cloth 33 is put into a wiping operation state of swinging left and right. Specifically, the third rotating cam 62 will be in a reciprocating rotation state similar to the way the swinging device is dragged by the rotating shaft 2 and the first ratchet 51. However, the reciprocating rotation is relative rotation with respect to the hanger 31, the initial position is determined by the sixth stopper 60 fixed to the hanging lug 311 of the hanger 31, the resetting is realized by the third return spring 65 sleeved on the hanging rod 313 driving the sleeve 314, and the fifth stopper 68 triggering the third pawl 63 to separate from the third ratchet wheel 61 is also installed on the hanging lug 311.

The wiping unit is reciprocated left and right due to the upper end of the connecting piece 32 being fixedly connected to the sleeve 314. When the third rotating cam 62 is reciprocally rotated about the rotating shaft 2, the length of the winding of the wire 64 made of a wire core on the third rotating cam 62 is varied, thereby bringing about the reciprocal movement of the sleeve 314. Here, since the cable 64 is mounted inside the spool 641, the spool 641 is not significantly deformed by the force applied to the cable 64, and the length pulling action of the third rotating cam 62 on the cable 64 is almost entirely reflected as the displacement of the spool 314. Because the spool 641 is adopted, the direction of the spool is not required to be changed by adopting a traditional rope pulley mechanism such as a fixed pulley, and the flexibility and the reliability of the system are greatly improved.

The left and right swinging of the wiping cloth 33 can enhance the contact to the side surface, the shoulder and other parts of the vehicle body, and effectively ensures the aim of covering and wiping the surface of the vehicle body by the wiping cloth 33 without leakage.

As described above, the control of the storage position when the wiping unit is stored and released is realized only by ensuring sufficient rotation time of the rotating shaft 2.

After the wiping operation is completed, the vehicle will leave the car wash. As shown in FIG. 1, when the vehicle exits the car washing room in a reverse mode, the floor type fan 8 is started, the air outlet 81 is aligned with the middle lower part of the vehicle body, the car wiping cloth strip 82 on the air outlet is guided by air flow in a ribbon mode to contact the vehicle body 4, and shakes and beats the lower hem of the vehicle body 4 along with wind. Meanwhile, the strong wind can further remove the accumulated water at the wheels and the like, so that a better water removing effect is realized.

As described above, the wiping unit does not perform a continuous 360 ° rotational movement around the rotating shaft 2 during the entire wiping process, but is suspended below the rotating shaft 2 as a whole, and generally, the lower middle portion of the wiping unit is in contact with the vehicle body 4 to be wiped. Therefore, the large-diameter operation space required by the traditional rotary wiping brush is avoided, the complex design of vehicle body distance detection, control and the like required by the wiping brush for keeping proper contact with the vehicle body is further avoided, and the reliability and safety of the operation of the equipment are also improved qualitatively.

As shown in fig. 2, the wiping cloths 33 are arranged in a plurality of layers in front and back and overlapped with each other, which is advantageous for achieving a good covering power for the surface of the vehicle body. The lower part of the wiping cloth 33 can further enhance the covering effect on all parts of the vehicle body by sewing the strip-shaped cloth strip 34 with water absorption, thereby realizing the traversing wiping of the vehicle body and avoiding omission.

When the wiping cloth 33 needs to be taken down for cleaning because of absorbing more stains, the connecting piece 32 and the wiping cloth 33 adopt buttons or/and male and female buttons, and the buttons or/and the male and female buttons can be detached by tearing the buttons or/and the male and female buttons by bare hands, so that the cleaning and drying device is quite convenient.

Further, the wiping unit may be pretreated in various ways by supplying clean water or wax water to the rotating shaft 2 in a state where the wiping unit is wound around the rotating shaft 2:

1) if the car washer is not operated for a long time, the wiping cloth 33 will become hard due to too low water content, which seriously affects the adhesion with the car body surface and directly weakens the wiping effect. When the clean water wets the wiping cloth 33 through the rotating shaft 2 and the spray holes thereof, the wiping cloth 33 can absorb water and soften, and the subsequent contact with the vehicle body 4 is more proper, so that the water removal effect of the wiping unit is ensured;

2) in winter, the wiping cloth 33 becomes hard due to freezing at low temperature. Under the condition, the electric heating device on the clean water pipeline heats the clean water in the pipeline, hot water is input through the rotating shaft 2, the wiping cloth 33 can be heated and softened, and the performance of the wiping cloth can be recovered;

3) in the daily use process, the wiping cloth 33 is soaked with the wax water, and the vehicle body 4 is wiped by the wax water absorbed by the wiping cloth 33, so that the material loss of a wax water spraying mode can be effectively reduced, and the effect is basically not influenced.

In the above water passing process, the rotating shaft 2 rotates forward to generate a proper centrifugal force, so as to promote the water flow to be discharged from the water outlet 22 and quickly permeate to the outer layer of the wiping unit.
