[0066] The working process of the present invention is as follows: before starting work every day, the water supply system of the car washing machine needs to be detachably connected and connected to the end of the steel pipe 1 of the water inlet pipe 10, and the servo motor 18 is turned on. The output end of the servo motor 18 drives the ball screw 1 to rotate, and the slider 23 matched with the ball screw 1 slides along the guide rail 22. Since the two sliders 23 are connected by a connecting block, the connecting block drives the lifting mechanism to move horizontally along the guide rail 22 to meet the water spraying needs at different horizontal positions. After moving to the appropriate position, the servo motor 18 is turned off, and the drive motor 3 44 is turned on. The output end is connected to the guide rail 22. Rod three 46 and connecting rod two 45 drive connecting plate three 42 to move, so that rotating cylinder 40 rotates, and then the cooperation between pawl 43 and inner ratchet 39 drives connecting shaft two 38 to rotate, and connecting shaft two 38 drives gear 28 to rotate through connecting shaft three, and gear 28 meshes with the rack on the side of lifting member 27, thereby driving lifting member 27 to move up and down along the lifting hole on the connecting block. After moving to the appropriate height, drive motor three 44 is turned off, and cylinder three is turned on. Cylinder three pushes moving rod 13 to move, and pressing member 25 contacts the side of lifting member 27 to fix the position of lifting member 27, and cylinder three is turned off. The positioning plate 14 and the two limiting plates 24 limit the lifting range of the lifting member 27 to ensure the stability and reliability of the lifting process. One of the cylinders 15 is turned on, and the cylinder 15 pushes the movable cylinder 17 to move to the appropriate position. The cylinder 15 is closed, and the movable cylinder 17 at the end of the cylinder 15 is turned on. The movable cylinder 17 pushes the limiting column 50 to move away from the movable cylinder 17 until the end of the limiting column 50 exceeds the outermost side of the connecting column 6 away from the cylinder 15. The movable cylinder 17 is closed (the limiting column 50 plays a limiting role); the other cylinder 15 is turned on, and the cylinder 15 pushes the movable cylinder 17 to move away from the movable cylinder 17. Cylinder 17 moves to the appropriate position, close this cylinder 15, open the movable cylinder 17 at the end of this cylinder 15, and the movable cylinder 17 pushes the limiting column 50 to move away from the movable cylinder 17. Close the movable cylinder 17, open this cylinder 15, and cylinder 15 drives the limiting column 50 to move toward the direction of cylinder 15 (this limiting column 50 plays a pushing role). The limiting column 50 pushes the connecting column 6 at the corresponding position to make the sliding part 13 move along the sliding groove. After moving to the appropriate position, open the adsorption part 2, and the adsorption part 2 cooperates with the bottom of the sliding groove of the support platform 2 to fix the sliding part 3 in the position of the sliding groove.

[0067] Close the cylinder 15, turn on the drive motor 14, the drive motor 14 drives the support plate 7 to rotate a certain angle, turn off the drive motor 14, turn on the drive motor 48, the drive motor 48 drives the fixed disc 49 to rotate, so that the adsorption member 1 rotates along the arc groove to the horizontal line with the center of the circle of the fixed disc 49, turn off the drive motor 48, turn on the adsorption member 1, the adsorption member 1 adsorbs the inner side of the arc groove, fixes the angle of the support plate 7, turns on the drive motor 29, the output end of the drive motor 29 drives the rotating shaft 2 to rotate between the two connecting plates 18, and the water spraying member 11 installed on the outer periphery of the rotating shaft 2 is then operated. When the pitch angle is adjusted to the appropriate pitch angle, the drive motor 2 9 is turned off and the cylinder 2 36 is turned on. The cylinder 2 36 pushes the rotating plate 35 to rotate, and the connecting shaft 1 34 drives the two connecting plates 2 33 to move. The arc-shaped member 30 is pulled to rotate around the rotating shaft 1 31 through the connecting rod 1 32. Since the two arc-shaped members 30 are distributed up and down, they approach the inner side of the ring cylinder 29 under the action of the connecting rod 1 32 and cooperate with the ring cylinder 29, thereby fixing the rotating shaft 2 and ensuring the stability of the pitch angle. The cylinder 2 36 is turned off, and the extraction pump 1 16 and the extraction pump 3 20 are turned on to make the multiple water mist nozzles on the side of the water spraying member 11 spray water.

[0068] In the present invention, during the water spraying process, a portion of water will enter the water spray box 1 through the sliding hole and the through hole 1 on the water spray box 1. After a period of time, the staff turns on the extraction pump 2 19. Under the action of the extraction pump 2 19, the suction pipe can extract the water in the water spray box 1 and replenish it into the steel pipe 1.

[0069] In the present invention, the extraction pump 16 and the extraction pump 3 20 can also be started before the horizontal movement mechanism is turned on, and the position and angle of the water spraying member 11 can be adjusted while spraying water.

[0070] In the present invention, during the movement of the sliding member 3 in the sliding groove, one of the limit posts 50 plays a limiting role, and the other limit post 50 plays a pushing role. When the connecting post 6 corresponding to the limit post 50 that plays a limiting role contacts this limit post 50, the functions of the two limit posts 50 are reversed, causing the sliding member 3 to move in the opposite direction again.

[0071] In the present invention, multiple multi-angle adjustable water spray devices for car washers of the present invention can be set according to the on-site conditions and needs. For example, two multi-angle adjustable water spray devices of the present invention can be set at one car wash position, and three or four multi-angle adjustable water spray devices of the present invention can be set at two car wash positions.

[0072] In the present invention, the above process can be adjusted according to the on-site conditions.

[0073] In the present invention, the above process can be automatically controlled by a controller.

[0074] The hardware configuration provided as a technical solution of the present invention is merely to facilitate the implementation of specific braking control based on the hardware facilities. The specific implementation of braking control and the braking control method are not the technical problems to be solved by the present invention and are not the subject of protection. Furthermore, the communication methods between the devices all adopt existing communication methods and are not the inventive point of this application.
