Description

Technical Field

[0001] The utility model relates to the technical field of car washing devices, in particular to a two-way automatic car washing device. Background Art

[0002] When freight vehicles enter and leave the factory, they need to spray water to wash the outer surface of the vehicle to remove dust and dirt on the surface of the vehicle in order to meet the needs of environmentally friendly transportation.

[0003] To prevent freight vehicles entering and leaving the factory from interfering with each other, the inventors attempted to install a two-way car wash at the factory entrance. Specifically, two platforms were installed at the factory entrance, each with a protective shield mounted above it. Two traffic lanes were formed between the shield and the platforms. One lane served as the entrance to the factory, while the other served as the exit. Each lane was equipped with a nozzle and water supply line, which sprayed water onto vehicles in the lanes to quickly remove dust.

[0004] However, in the above technical solution, the nozzle's position in the traffic lane is relatively fixed, making it difficult to directly spray water over most areas of the vehicle. A longer spray interval is required to achieve an optimal cleaning effect. Furthermore, in the above technical solution, once the vehicle has fully entered the traffic lane, the operator needs to manually open the valve in the water supply line. Consequently, while the front of the vehicle and most of the vehicle body are in the traffic lane, cleaning cannot be performed. In other words, this arrangement does not allow for full utilization of the time the vehicle has in the traffic lane, nor does it facilitate further improvement in vehicle cleaning efficiency. Utility Model Content

[0005] The utility model provides a two-way automatic car washing device, which can solve at least one of the above technical problems.

[0006] In order to solve the above technical problems, one or more embodiments of the present invention provide a two-way automatic car washing device, which has a first direction and a second direction that are horizontal and perpendicular to each other, including two platforms arranged side by side along the second direction, and protective covers are installed above the platforms respectively. The protective covers are open at both ends along the first direction, and the protective covers and the platforms enclose a driving channel.

[0007] Water pipes extending in the first direction are provided on the sidewalls and top wall of the shield, which are perpendicular to the second direction. The water pipes are connected to the water supply pipeline. Sprinklers are located on the sidewalls of the water pipes, and a solenoid valve is installed between the nozzles and the water pipes, allowing the water pipes to be raised and lowered vertically and positioned. First laser rangefinders are located on the outside of the entrance and exit of the traffic lane to detect the distance of vehicles entering the traffic lane. A second laser rangefinder is located on the top wall of the shield to detect the height of vehicles.

[0008] The beneficial effects of one or more of the above technical solutions are:

[0009] This solution features two platforms, each with a protective shield. Two traffic lanes are enclosed between the two platforms and the shield. Sprinklers and water pipes are installed in each lane, connected to the water supply line. This arrangement allows vehicles entering and leaving the factory to be sprayed and cleaned separately from each other, ensuring that vehicles entering and leaving the factory do not interfere with each other.

[0010] In this solution, a second laser rangefinder is provided on the top wall of the shield, which can measure the height of the vehicle entering the driving channel, and then adjust the height of the water pipe and the nozzle according to the height information, so that the cleaning water sprayed by the nozzle can fall evenly on the vehicle to be cleaned, avoiding the probability of cleaning water being sprayed into areas other than the vehicle due to the nozzle being too far away from the vehicle.

[0011] In this solution, the water pipes on the top wall of the shield and the water pipes on the side wall of the shield can be raised and lowered vertically, so that the water pipes can drive the nozzles to change their own heights, so as to achieve cleaning of different height positions of the vehicle vertically and improve the cleaning effect of the vehicle beams.

[0012] In this solution, a first laser rangefinder is installed at the entrance and exit of the driving channel. This first laser rangefinder can measure the distance of the vehicle entering the driving channel, thereby facilitating the water spray cleaning operation of the nozzle before the vehicle completely enters the driving channel. In addition, the first laser rangefinder can be used to determine the position of the vehicle in the driving channel, thereby facilitating the shutdown of nozzles far from the vehicle, thereby reducing the waste of cleaning water.

DETAILED DESCRIPTION

[0019] In order to clearly illustrate the technical features of this solution, the present invention is described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0020] See also Figure 1-Figure 5 A typical embodiment of the present invention provides a two-way automatic car washing device, which has a first direction and a second direction that are horizontal and perpendicular to each other, including two platforms 1 arranged side by side along the second direction, and protective covers 2 are respectively installed above the platforms 1. The protective covers 2 are open at both ends along the first direction, and the protective covers 2 and the platforms 1 form a driving channel.

[0021] For details, see Figure 1 Here, the shield 2 comprises two vertically arranged side panels 201, perpendicular to the second direction. The tops of the two side panels 201 are secured by curved panels 202. The lower ends of the side panels 201 are secured to the platform 1 via angled connectors and bolts. The vehicle access channel is formed by the top surfaces of the curved panels 202, the upper surface of the platform 1, and the inner walls of the two side panels 201.

[0022] In this embodiment, the sidewalls and top wall of the shield 2, perpendicular to the second direction, are each provided with a water pipe 3 extending in the first direction. This water pipe 3 is in communication with the water supply pipe 3. A nozzle 4 is located on the sidewall of the water pipe 3, and a solenoid valve 14 is installed between the nozzle 4 and the water pipe 3, allowing the water pipe 3 to be raised and lowered vertically and positioned. First laser rangefinders 12 are located on the outside of the entrance and exit of the traffic lane to detect the distance a vehicle has entered the traffic lane. A second laser rangefinder 13 is located on the top wall of the shield 2 to detect the vehicle's height.

[0023] Specifically, the nozzles 4 here are evenly distributed on the side walls of the water pipe 3 along the first direction. The water pipe 3 on the top wall of the protective cover 2 is the first water pipe 301, and the water pipe 3 on the side wall of the protective cover 2 is the second water pipe 302. More specifically, the opening direction of the nozzle 4 on the first water pipe 301 is downward; the opening direction of the nozzle 4 on the second water pipe 302 is horizontally toward the center of the driving channel.

[0024] In order to facilitate the installation of the electromagnetic valve 14, a branch pipe is provided beside the side wall of the water pipe 3. The branch pipe can be a hose, and the electromagnetic valve 14 is connected in series in the branch pipe. One end of the branch pipe is connected to the water pipe 3, and the other end is connected to the nozzle 4.

[0025] Specifically, in this embodiment, the upper surface of the platform 1 includes three parts, namely, a first inclined surface 101, a plane 102 and a second inclined surface 103 parallel to the second direction. The upper ends of the first inclined surface 101 and the second inclined surface 103 are connected to the two ends of the plane 102 along the first direction, that is, the first inclined surface 101, the plane 102 and the second inclined surface 103 are combined to form a trapezoid.

[0026] When in use, the vehicle can easily enter and exit the plane 102 by utilizing the first inclined surface 101 and the second inclined surface 103 of gradually varying heights. Generally, in vertical projection, the projections of the first inclined surface 101 and the second inclined surface 103 are outside the projection of the shield 2; the projection of the plane 102 coincides with the projection of the shield 2.

[0027] In this embodiment, the shields 2 on the two platforms 1 are respectively the first shield 2 and the second shield 2 . The first shield 2 and the second shield 2 share the same vertical partition, which is perpendicular to the second direction.

[0028] Specifically, the platform 1 can be made of concrete or metal to improve its support capacity, and the shield 2 can be made of plastic to reduce weight.

[0029] In this embodiment, the first water pipe 301 is driven by a first lifting assembly to achieve lifting; the second water pipe 302 is driven by a second lifting assembly to achieve lifting.

[0030] As one specific structural form, the first lifting component is one or more of an electric push rod 5, a pneumatic cylinder and a hydraulic cylinder.

[0031] Taking the electric push rod 5 as an example, a plurality of vertical electric push rods 5 are provided on the top wall of the outer cover. The upper end of the electric push rod 5 is fixed to the top wall of the outer cover, and the lower end is fixed to the first water pipe 301 .

[0032] In this embodiment, the second lifting component is a winch 6, and the side wall of the protective cover 2 is provided with a vertical guide groove 7, a slider 8 is provided in the guide groove 7, the slider 8 is fixed to the second water pipe 302, and the free end of the wire rope in the winch 6 is fixed to the second water pipe 302.

[0033] Specifically, the hoist 6 includes a drum and an electric motor. The motor body is fixed to the outer wall of the housing. The output shaft of the motor is coaxially fixed to the drum. A steel wire rope is wound around the drum. One end of the steel wire rope is fixed to the drum, and the other end is free and is used to be fixed to the second water pipe 302.

[0034] See also Figure 1 The winch in this embodiment is a double-head winch, that is, one motor drives two drums, each drum has two wheel grooves, and a steel wire rope is wound in each wheel groove. The steel wire rope passes through the outer cover and enters the driving channel and is fixed to the second water pipe in the driving channel.

[0035] It is known that in some other embodiments, the first lifting assembly can also use a winch 6, and the second lifting assembly can use one or more of an electric push rod 5, a pneumatic cylinder, and a hydraulic cylinder. The specific connection method can be set by a person skilled in the art.

[0036] In this embodiment, the platform 1 has a water tank 9 with an open upper end. A grille 10 is detachably installed at the open upper end of the platform 1. The middle of the water tank 9 is connected to the wastewater recovery pipeline.

[0037] Specifically, the water tank 9 here only occupies a portion of the upper surface of the platform 1, and can be arranged in the middle of the platform 1 along the second direction.

[0038] In this embodiment, a filter screen 11 is further installed in the water tank 9 to separate the water tank 9 into upper and lower parts. The inlet of the wastewater recovery pipeline is located at the lower part of the filter screen 11. This arrangement facilitates the use of the filter screen 11 to filter out larger volumes of waste in advance, preventing it from moving into the wastewater recovery pipeline, thereby preventing the wastewater recovery pipeline from being blocked by large volumes of waste.

[0039] Specifically, the water tank 9 here can be a square tank or a trapezoidal tank, which can be set by those skilled in the art.

[0040] In this embodiment, the filter screen 11 can be lifted and lowered vertically and positioned.

[0041] In one specific structural form, sliding blocks are installed around the filter screen 11. A vertical sliding groove is provided on the inner wall of the water tank 9, and the sliding blocks are installed in the sliding groove. A spring is installed between the grille at the top of the water tank 9 and the filter screen 11. The spring's elastic force suspends the filter screen 11 in the middle of the water tank 9.

[0042] In this embodiment, a controller is further included. The controller can receive signals from the first laser rangefinder 12 and the second laser rangefinder 13 , and can control the raising and lowering of the water pipe 3 respectively.

[0043] Working principle: When using this device, the first laser rangefinder 12 and the second laser rangefinder 13 are triggered as soon as the vehicle enters the driving lane. The second laser rangefinder 13 can adjust the height of the first water pipe 301 and the second water pipe 302 according to the height of the vehicle, so that the distance between the nozzle 4 on the first water pipe 301 and the second water pipe 302 and the vehicle is not greater than the set value.

[0044] After the vehicle begins to enter the driving lane, the nozzle 4 at the vehicle position gradually opens to clean the vehicle. When the vehicle completely enters the driving lane and stops, the second water pipe 302 is controlled to rise and fall so that the nozzle 4 at the second water pipe 302 can vertically clean parts of the vehicle at different heights.

[0045] The cleaning water sprayed from the nozzle 4 falls into the water tank 9 after washing the vehicle, and the large volume of dirt is filtered by the filter 11 before entering the water tank 9. After using for a period of time, the grille and filter 11 are pulled up with a hook to clean the dirt on the upper surface of the filter 11, and then it is put back into the middle of the water tank 9.

[0046] The above specific implementation methods cannot be used as a limitation on the protection scope of the present utility model. For those skilled in the art, any replacement, improvement or transformation made to the implementation methods of the present utility model falls within the protection scope of the present utility model.

[0047] Anything not described in detail in the present invention is well known to those skilled in the art.
