Description

Technical Field

[0001] The utility model relates to the field of vehicle cleaning, in particular to a vehicle cleaning device. Background Art

[0002] Before vehicle maintenance, cleaning is required to fully expose the fault location and ensure accurate subsequent vehicle repairs. Existing automatic vehicle washing lines feature a gantry with a water supply pipe installed. As the vehicle passes through the gantry, the nozzles on the water supply pipe spray water on the vehicle to achieve the purpose of cleaning. While automatic vehicle washing lines improve cleaning efficiency compared to manual cleaning, the existing water supply pipe outlet is only equipped with a single spray nozzle. The spray coverage area is not large enough, and the water pressure from the nozzle of the single spray nozzle is insufficient, resulting in poor vehicle cleaning results and some areas not being cleaned. For example, patent CN 208615902 U discloses an automatic cleaning mechanism for a rail vehicle, comprising a head cleaning device 3 arranged at the top of the bottom, a flushing device 4 arranged at the top of the base 1 and located next to the head cleaning device 3, etc. The head cleaning device 3 comprises a support assembly 3a, a water spray assembly 3b and a first cleaning assembly 3c. The flushing device 4 comprises a flushing assembly 4a, which comprises a water receiving pipe 4b and a flushing rack 4c. The water receiving pipe 4b is fixedly arranged at the top of the base 1 and is connected to the flushing rack 4c. The flushing rack 4c is provided with a plurality of flushing heads 4d. It only has one set of flushing assemblies, and the flushing heads 4d are arranged at the top and both sides of the vehicle. There is a problem that the bottom of the vehicle is not cleaned. The flushing head 4d is a single nozzle, and the water spray coverage area is insufficient.

They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In the description of this utility model, unless otherwise specified, "several" means two or more.

[0032] like Figures 1-8 The embodiment of the present utility model provides a vehicle cleaning device, comprising a water supply pipe 1 fixed on a gantry, the water supply pipe 1 being provided with a plurality of water outlets, each of which is provided with a Y-shaped three-way double DC nozzle 2, the Y-shaped three-way double DC nozzle 2 comprising a Y-shaped three-way 3 and a DC nozzle 4 for spraying water onto the vehicle, the Y-shaped three-way 3 comprising a water inlet end and two water outlet ends, the diameter of the water outlet end being smaller than the diameter of the water inlet end, the water inlet end being connected to the water outlet of the water supply pipe, and each of the water outlet ends being connected to one of the DC nozzles 4. In this embodiment, the Y-shaped three-way 3 is made of 304L stainless steel, the DC nozzle 4 has a wall thickness of 1mm and is made of 304L stainless steel. In this embodiment, the DC nozzle 4 gradually contracts in a direction away from the Y-shaped three-way 3, and the DC nozzle 4 comprises a flared end and a narrow end for discharging water, the flared end being connected to the water outlet end of the Y-shaped three-way 3.

[0033] The existing single spray nozzle only includes one spray nozzle, that is, there is only one spray nozzle at the water outlet of the existing water supply pipe. The water spray range of the spray nozzle is not large enough, and the water outlet pressure is insufficient, resulting in poor vehicle cleaning effect and the presence of some areas that are not cleaned. The utility model is equipped with a double DC nozzle at the water outlet of each water supply pipe 1, that is, a double-nozzle cleaning operation is realized at one water outlet of the water supply pipe 1, and the water spray coverage is wider, so that the outer surface of the vehicle can be cleaned. In addition, the water outlet pressure of the DC nozzle 4 of the utility model is stronger than that of the spray nozzle of the existing single spray nozzle, reaching 1.7Mpa, which has a better cleaning effect on the vehicle.

[0034] In the present invention, water in the water supply pipe 1 flows through the Y-shaped tee 3 at each water supply pipe outlet and is then divided into two direct current nozzles 4, which discharge water to wash the vehicle.

[0035] In the present invention, a number of water supply pipes 1 are arranged at intervals on the gantry along the direction in which the vehicle passes through the gantry. In the present embodiment, the water supply pipe 1 is in a U-shape, and the water supply pipe 1 includes two vertical pipes 5 and two horizontal pipes 6. The two vertical pipes 5 and the two horizontal pipes 6 form a U-shaped water supply pipe. The vertical pipe 5 is provided with a number of Y-type three-way double DC nozzles 2 on the pipe section above the track surface. Each of the Y-type three-way double DC nozzles 2 is arranged at intervals in the vertical direction. In the present embodiment, the spacing between two adjacent Y-type three-way double DC nozzles on the vertical pipe is 250 mm. The horizontal pipe 6 located above the track surface 8 and the horizontal pipe 6 located below the track surface 8 are both provided with a number of Y-type three-way double DC nozzles 2. Each of the Y-type three-way double DC nozzles 2 is arranged at intervals in the horizontal direction. In the present embodiment, the spacing between two adjacent Y-type three-way double DC nozzles on the horizontal pipe is 200 mm, and the bottom horizontal pipe is 554 mm away from the track surface. The number and spacing of the Y-type three-way dual DC nozzles in the figure are for reference only. They can be adjusted according to the type and size of the vehicle to ensure that the water spray can cover the entire vehicle.

[0036] A water supply pipe 1 is provided around a vehicle track 7, which is mounted on track piers. The track piers are spaced apart along the vehicle's travel direction. A transverse pipe 6, located below the track surface, is located between adjacent track piers along the vehicle's travel direction. As the vehicle travels along the track 7 and passes through the gantry, it is cleaned.

[0037] In this embodiment, the external water supply source is connected to the riser 5 of the water supply pipe at the height of the track surface 8. Figure 2 As shown, the water supply is divided upward and downward, Figure 2 In the embodiment, both the left and right vertical pipes 5 are connected to an external water source. In another embodiment, the position where the external water source is connected to the water supply pipe can be adjusted according to actual conditions. In another embodiment, each vertical pipe 5 and each horizontal pipe 6 can also be connected to a water source independently.

[0038] Figure 2-Figure 8 The bold dotted line in the figure represents the extension line of the water supply pipe, indicating that the vertical pipe 5 and the horizontal pipe 6 can be designed to the required length according to actual conditions.

[0039] Along the direction of vehicle travel, the distance between two adjacent water supply pipes can be set based on a comprehensive consideration of factors such as the length of the washing line, the length of vehicles of different models, and the number of vehicles being washed simultaneously.

[0040] In the present invention, the DC nozzle 4 of the Y-shaped three-way double DC nozzle 2 replaces the spray nozzle of the existing single spray nozzle. The water outlet pressure of the DC nozzle 4 is enhanced to 1.7 MPa, the cleaning water pressure is stronger, and the cleaning effect is better.

[0041] The Y-shaped three-way double DC nozzle 2 adopted in the present invention has an additional nozzle at each water outlet of the water supply pipe compared to the existing design, which has a higher vehicle cleaning coverage rate and greatly improves the cleaning effect.

[0042] The Y-shaped three-way dual DC nozzle 2 provided by the utility model can greatly improve the cleaning efficiency and effect of the vehicle automatic cleaning line, and provide a guarantee for the subsequent accurate repair of vehicles.

[0043] The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
