Abstract
Description
Technical Field
[0001] This utility model relates to the field of wheel washing machine technology, and in particular to a vehicle wheel washing machine. Background Technology
[0002] Currently, at construction sites, mines, landfills, and other locations, vehicles are typically required to have their bodies and tires washed before leaving the work area and entering public roads to remove attached mud, dust, and other pollutants, thus preventing pollution of roads and the urban environment.
[0003] High-pressure water jet washing machines rely entirely on water for the entire cleaning process. Even with a circulating water tank, the water consumption and evaporation are still enormous, which does not align with the trend of water conservation and environmental protection. Furthermore, the washing process generates a large amount of wastewater mixed with mud and sand, requiring complex sedimentation tanks and subsequent treatment systems, which increases the floor space and operating costs. Moreover, vehicles carrying a large amount of water after washing can easily cause slippery roads, and in cold winter regions, the residual water can freeze, posing a serious safety hazard. Utility Model Content
[0004] The purpose of this invention is to provide a vehicle cleaning device that can effectively remove pollutants from the vehicle body while maximizing water conservation and suppressing dust.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a vehicle wheel washing machine, comprising a main frame, wherein the main frame is divided into a dust removal section and a drying section of equal length along the length direction, the main frame is equipped with a wind duct system and a water mist dust suppression system, and the main frame is equipped with a control unit;
[0006] The air duct system includes a fan installed at one end of the main frame and a main air duct connected to the fan. After the main air duct extends to the middle of the main frame, several secondary air ducts are installed. The secondary air ducts extend to the dust removal section and the drying section respectively. Electric air valves are provided at the connection between the main air duct and each secondary air duct. Multiple gas purging nozzles are installed on the secondary air ducts.
[0007] The water mist dust suppression system is located in the dust removal section. The water mist dust suppression system includes a water tank, a high-pressure water pump, water pipes laid along the dust removal section, and water mist nozzles.
[0008] As a further description of the above technical solution: the auxiliary air duct is arranged along the vehicle's direction of travel, and the gas blowing nozzles cover the roof, sides, and wheel arch areas.
[0009] As a further description of the above technical solution: the water mist nozzle forms a continuous mist curtain in the dust removal section, and its spray range overlaps with the airflow coverage area of the gas purging nozzle, together suppressing the dust height to below 2.5m.
[0010] As a further description of the above technical solution: the control unit is an industrial programmable logic controller, equipped with a dust sensor. When the dust sensor detects that the dust content in the dust removal section is lower than a preset threshold, the control unit performs a mode switch.
[0011] As a further description of the above technical solution: the control unit is configured as follows:
[0012] When the dust removal section is in operation, open the electric air valve of the dust removal section and start the fan and high-pressure water pump;
[0013] Based on the dust content signal detected by the dust sensor, when switching to the drying mode, the electric air valve and high-pressure water pump of the dust removal section are closed, and the electric air valve of the drying section branch is opened.
[0014] As a further description of the above technical solution: the dust sensor is a GP2Y1014AU0F type, SDS031 type or SDS3602 type particulate sensor.
[0015] As a further description of the above technical solution: When the dust removal section is working, the high-pressure airflow released by the gas blowing nozzle strips off the adhering substances on the vehicle surface, while the mist curtain formed by the water mist nozzle combines with the dust and settles. When the drying section is working, the high-pressure airflow continues to act on the vehicle surface until the preset drying time ends.
[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:
[0017] 1. By combining high-pressure airflow purging with high-pressure water mist dust suppression, the high-pressure airflow serves as the main power source for stripping and cleaning in the dust removal section. At the same time, the mist curtain formed by the water mist nozzles can instantly capture and settle the dust raised by the airflow, effectively controlling it within a low-altitude range. This solves the serious secondary dust problem caused by traditional wind-blown dust removal methods and has significant environmental advantages.
[0018] 2. The dust removal process mainly relies on wind power, and water is only used for dust suppression in the form of atomization, rather than as a washing medium. Compared with traditional high-pressure water washing wheel washing machines, water consumption is greatly reduced, saving water resources. At the same time, it also eliminates the need for a large and complex sedimentation tank and sewage treatment system, reducing the equipment's infrastructure costs and long-term operation and maintenance costs.
[0019] 3. Since the vehicle has been dried before leaving the equipment, the phenomenon of water dripping from the vehicle body is effectively reduced, avoiding pollution and slipperiness of public roads. Especially in winter, this function can effectively prevent the water carried by the vehicle from freezing on the road surface, eliminating potential traffic safety hazards, and making this equipment adaptable to a wider range of geographical and climatic conditions.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figure 1 - Figure 2 This utility model provides a technical solution: a vehicle wheel washing machine, including a main frame, which is functionally divided into a dust removal section on the right and a drying section on the left. The total length of the entire device is 24,000 mm, of which the dust removal section and the drying section are each 12,000 mm long. The overall width of the device is 4,500 mm and the height is 4,500 mm.
[0026] The air duct system is the core component of this wheel washing machine. A fan 11 is installed at one end of the main frame. The fan 11 is connected to the main air duct 12. After the main air duct 12 extends to the middle of the main frame, it branches and connects to the dust removal section and the drying section. The main air duct 12 is connected to several auxiliary air ducts 13. An electric air valve 14 is installed at the connection point between the main air duct 12 and the auxiliary air ducts 13. The electric air valve 14 automatically opens and closes according to the working process to control whether the airflow enters the dust removal section or the drying section.
[0027] On all the secondary air ducts 13, several gas purging nozzles 15 are installed. These gas purging nozzles 15 are arranged along the length of the duct with a spacing of about 3000 mm.
[0028] In addition to the air duct system, the device is also equipped with a water mist dust suppression system in the dust removal section. The system includes a water tank 16, a high-pressure water pump 17, and a water pipe 18 connected to the water pump 17. The water pipe 18 is laid along the frame of the dust removal section and has several water mist nozzles 19 fixed on its outer wall. The spacing between the water mist nozzles 19 is 200mm. Its function is to spray high-pressure water mist while blowing air to remove dust, so as to control the dust raised to a height of less than 2.5 meters and avoid secondary pollution.
[0029] The entire system is controlled by automated logic. For example, the system includes a dust sensor. When the dust sensor detects that the dust content in the air in the dust removal area has dropped to a preset level, it will illuminate a light to indicate that the vehicle can enter the drying area. At this time, the control system will automatically close the electric air valve 14 of the dust removal section and stop the water pump 17, while opening the electric air valve 14 of the drying section and switching to the drying mode.
[0030] The dust sensor can be selected from GP2Y1014AU0F, SDS031 or SDS3602 models.
[0031] When a vehicle is about to enter the wheel washing machine, the control unit (using an industrial programmable logic controller) keeps the electric air valve 14 corresponding to the drying section closed and the electric air valve 14 corresponding to the dust removal section open, while the fan 11 is in standby mode. When the system receives a vehicle entry signal or a manual start command, the fan 11 starts and supplies air to the auxiliary air duct 13 of the dust removal section through the main air duct 12. At the same time, the control unit drives the water pump 17 to start, so that the water in the water tank 16 is transported to the water mist nozzle 19 of the dust removal section through the water pipe 18, forming a mist curtain covering the dust removal section.
[0032] After the vehicle enters the dust removal section, the fan 11 releases high-pressure airflow through the auxiliary air duct 13 and the gas blowing nozzle 15 to blow away the vehicle's exterior, removing loose materials such as floating dust and mud. At the same time, water mist nozzles 19 form a fog curtain in the dust removal section at a set interval. The water mist and airflow work together to capture and suppress the dust that is lifted, keeping its actual lifting height below 2.5m, thereby reducing the risk of secondary pollution. The distribution of airflow in the dust removal section is achieved by the coordinated action of several auxiliary air ducts 13 to ensure the blowing coverage of key parts such as the roof, sides, and wheel arches.
[0033] During the dust removal process, the dust sensor continuously monitors the dust content in the air within the dust removal section. When the dust content detected by the dust sensor reaches or falls below the preset cleaning threshold set by the control unit, the control unit issues an indicator light to prompt the driver to move the vehicle to the drying section.
[0034] Before the vehicle enters the drying section, the control unit first controls the electric air valve 14 of the dust removal section to close and stops the water supply of the high-pressure water pump 17. Then the control unit opens the electric air valve 14 corresponding to the drying section, so that the airflow provided by the fan 11 is distributed through the main air pipe 12 to the auxiliary air pipe 13 and the corresponding gas purging nozzle 15 of the drying section, thereby achieving the drying treatment of the vehicle entering the drying section.
[0035] The airflow in the drying section is mainly used to disperse residual water droplets on the vehicle surface and promote surface drying. After drying is completed, the control unit stops the fan 11 or puts it into standby mode according to the preset drying time or external judgment conditions, such as the operation process control signal, and completes the end prompt of one operation cycle.
[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
