Description

Urban dust cleaning system and urban dust cleaning method

Technical Field

The invention relates to a lane, a lane cleaning system comprising the lane, an urban area dust cleaning system comprising the lane, application of the lane cleaning system and the urban area dust cleaning system, and an urban area dust cleaning method.

Background

In recent years, governments have adopted many effective measures for governing and improving urban air quality, such as changing coal into gas, improving fuel standards, restricting motor vehicles, and the like.

It is still optimistic that in some cities throughout the year one may obtain brief days of dustless (including haze) and blue days from periods of heavy convection, rain or snow, after which the transition in air quality in urban areas characterised by an air quality index from excellent, good to light pollution (air quality index 101-150) will generally not exceed three days. This phenomenon indicates that there is still some sustainable and stable source of dust (including haze) pollution in urban areas.

Disclosure of Invention

The invention aims to solve the technical problem of how to clean dust in urban areas, in particular to the problem of cleaning dust of motor vehicle lanes.

The inventors have found that a motor vehicle traveling in urban areas, in particular a motor vehicle traveling on a non-rail track, behaves as follows: (1) The dust haze which is deposited on the driveway and the periphery is re-raised through repeated rolling of the wheels, disturbance of the vehicle body to the atmosphere and the like, and the raised dust (also called secondary raised dust) is suspended in the driveway and the atmosphere at the periphery of the driveway or dispersed to residential areas under the driving of breeze; (2) fine particles generated by abrasion of tires and road surfaces; (3) Dust is deposited on the bodywork of motor vehicles which are kept clean, and once on the road, this dust is at least partially re-introduced into the atmosphere under the impact of the air flow; (4) For fuel and gas-fired motor vehicles, emission of engine exhaust gas including water, carbon dioxide, solid particles and the like has become a main source of pollution caused by suspended solid particles in the atmosphere around urban areas, particularly urban roads.

In reality, although rainfall or sanitation department regularly or irregularly sprinkles or washes the operation to the lane, can play certain suppression effect to the raise dust, the problem is: (1) In the manual road sprinkling and washing operation, the motor vehicle running on the lane can wind and splash muddy water on the road surface, so that the vehicle body (such as wheels or chassis) is polluted; (2) The manual road sprinkling and washing operation forms accumulated water on the road surface, and most of solid particles in the accumulated water are still randomly deposited on the surface of the motor vehicle road except for part of the solid particles are migrated by the motor vehicle winding belt.

These problems, together with the fact that asphalt or cement road surfaces are generally not more than a day from wet to dry, cause vehicles and driveways to quickly return to their normal state after rain or manual watering, entering a constant and stable role that causes dust raising and air pollution. Therefore, how to effectively remove the dust haze deposited on the motor vehicles and the motor vehicle lanes and block the deposited dust haze from rising again becomes a prominent problem for urban air treatment.

The invention relates to the following contents:

in a first aspect, the present invention provides a lane, the lane at least includes a recessed belt along a longitudinal direction, the recessed belt is disposed on the lane to meet normal use of the lane, and when the lane is washed, road surface sewage is gathered towards the recessed belt.

In a second aspect, the present invention provides a lane cleaning system comprising a lane, the lane being the lane provided by the first aspect of the present invention.

In a third aspect, the present invention provides an urban dust cleaning system, which includes a lane cleaning system, where the lane cleaning system is the lane cleaning system provided in the first aspect of the present invention.

In a fourth aspect, the invention provides a dust cleaning method for urban areas, which comprises the steps of longitudinally arranging at least one sunken zone along a lane, wherein the arrangement of the sunken zone on the lane meets the normal use requirement of the lane, and when the lane is washed, road surface sewage is gathered towards the sunken zone.

In a fifth aspect, the foregoing first, second and third aspects of the invention are applied.

Different from the prior art, the lane provided by the invention comprises the sunken zone, and dust haze on the road surface is gathered along with water flowing to the sunken zone during natural rainfall and artificial sprinkling washing operation, so that the lane has a self-purification function. The lane, the lane cleaning system comprising the lane and the urban dust cleaning system can reduce and remove dust haze deposited on the road surface of the lane, so that the circulation of the dust haze in the urban area is blocked or at least partially blocked.

Detailed Description

In the invention, the lane is also called as a motor lane or a roadway and refers to a road through which a motor can pass in an urban road. The motor vehicle is a vehicle driven or drawn by a power device and running on the road for passengers or for transporting articles and performing engineering operation. For example, the motor vehicles include, but are not limited to, automobiles, rail and trackless internal combustion or steam locomotives, trams, trolleybuses, hybrid vehicles.

The zone in an urban road where a tandem of vehicles can safely travel is called a lane. The road surface of a lane is divided into a wheel track belt and a non-wheel track belt in the transverse direction. One lane (except for abnormal rail traffic such as single rail and suspension) comprises two wheel-track belts, a non-wheel-track belt between the two wheel-track belts, also called an inner non-wheel-track belt, and a non-wheel-track belt on the other side of each wheel-track belt, also called an outer non-wheel-track belt. The basic properties of lanes in urban roads are described in Liu Jingjiang et al (urban road engineering design, chemical industry Press 2016 (12), pages 74-75), incorporated herein by reference. For example, the width of one lane is 3-3.75m. According to the invention, the division of the tracking belt and the non-tracking belt can be: the middle 0.3-0.9m is the inner non-wheel track belt part, two wheel track belt parts are respectively arranged at two sides of the inner non-wheel track belt by 0.4-1m, and the rest is the two outer non-wheel track belt parts. Generally, the outer non-wheel-track zone comprises the occupied areas of lane boundaries (including white, yellow solid and dashed lines), road flat stones, isolation piers, isolation nets, guardrails and the like.

In the present invention, the setting includes design, installation and arrangement. The fugitive dust comprises solid particles forming haze

According to the first aspect of the present invention, when the lane is washed, the road surface sewage is gathered towards the depressed zones, which means that the sewage formed by the washing lane migrates towards the depressed zones under the action of gravity, thereby purifying the road surface. With satisfying the normal use of lane, and when washing the lane, road surface sewage to the sunken area assembles as the prerequisite, can be to the sunken area does multiple design. For example, the recessed bands in cross-section may be, but are not limited to, V-shaped, U-shaped, W-shaped, or,

One or more of the grooves of the circular (or elliptical) segment type may also be one or more of the variants formed by one or more of them. The recessed strip may be continuous or discontinuous in a section of lane. The depressed zones may be formed in a new paving construction, for example, by designing the pavement of the tread belt portion to be opposite to the inner non-tread belt and the outer non-tread beltAt least one of the convex curved surfaces forms a V-shaped concave belt; corresponding recessed strip preforms can be prefabricated, for example, to have

The prefabricated member with the round (or oval) segmental hole cavity structure is formed by paving in road construction (including newly paving and reconstructing roads); it can also be formed directly on an existing roadway by means of cutting and ripping. When the prefabricated member is constructed on the existing driveway, the prefabricated member is preferably embedded into the groove and laid after the groove is formed on the existing road surface. The preform may be made using any of the prior art techniques. For example, a preform made of cement and steel reinforcement; a preform stamped from metal; prefabricated parts prefabricated from engineering plastics, etc.

Preferably, the recessed belts are arranged on the non-wheel-track belts of the lane, the number k of the recessed belts on one section of the lane is 1 to n-m, n is the number of the non-wheel-track belts on the section of the lane, and m is the number of the shared non-wheel-track belts on the section of the lane. Multiple or multiple recessed bands may be included on the same non-track band, where their collection is considered a recessed band.

Optionally, the recessed zone comprises a solid particulate settling zone. The existence of the solid particle settling zone is beneficial to further enrichment of the solid particles. For a sunken belt arranged on a horizontal or nearly horizontal lane, the subsidence area can be a subsidence belt which is arranged at the bottom of the sunken belt and is further narrowed relative to the sunken belt; for the sunken zone arranged on the ramp, the settling zone can be a settling tank arranged on the sunken zone in a subsection mode, and the settling tank has the function of controlling the slow flow of the downflow sewage besides providing the settling zone for solid particles.

Alternatively, the depressed zone may comprise a water-permeable region comprising a portion provided with water-permeable holes at the bottom and/or sides of the depressed zone, etc.

In the invention, the driveway comprises a gutter inlet. The gully is of conventional design in a lane drainage system and is not described herein.

Researches show that when the lane is manually flushed, the sewage gathered in the sunken zone can not overflow into a lane drainage system through the road surface, and the method is favorable for improving the flushing effect of the road surface. In particular implementations, the potential for such overflow may be controlled or eliminated in different ways including: (1) One or more sunken zones with water capacity matched with the water consumption for lane flushing are arranged; (2) Synchronously recycling the sewage to discharge the sewage gathered in the sunken zone in time; (3) The overflow port communicated with the driveway rainwater port and the like are arranged to control the sewage gathered in the sunken zone not to overflow into the driveway drainage system through the road surface. Based on this, the present invention does not particularly limit the amount of water contained in the depressed zones.

The invention provides that the properties of the lane determine its own purification function, including the purification of the road surface of the lane, which is achievable under natural rainfall conditions. Therefore, the lane cleaning system provided by the invention is formed by the lane. The system needs manual intervention to clean the sediments in the concave zone regularly or irregularly, and is suitable for being used as a cleaning system for branches in urban roads.

According to a second aspect of the invention, other configurations of the lane cleaning system may be flexibly selected depending on the particular situation. For example, the lane washing system includes a lane flushing device and/or a sewage recovery device. Wherein, the lane washing device is like the road cleaning car, the sewage recovery unit is like sewage recovery pond and sewage recovery car etc.. When the lane washing device is a road cleaning vehicle and the sewage recovery device is a sewage recovery vehicle, the lane washing device and the sewage recovery device can be independent from each other or integrated with each other. For example:

in one embodiment, the lane-flushing device is a road-cleaning vehicle and the waste-water recovery device is a waste-water recovery vehicle equipped with a water-suction system. They may constitute the lane washing system of the present invention, either alone or together with the lane provided by the present invention.

In one embodiment, the lane flushing device and the sewage recovery device are integrated on the same trolley, and the vehicle is provided with a water spraying system and a water absorbing system at the same time, and the water spraying system and the water absorbing system are shared or respectively provided with a water tank. The vehicle and the lane provided by the invention form the lane cleaning system.

Preferably, the lane flushing device comprises a water spraying system matched with the lane, and the sewage recovery device comprises a sewage pump matched with the lane. The matching is premised on ensuring the efficiency of road washing and sewage recovery, for example, a water spraying system matched with the lane comprises a spray head which is adjusted to make the sprayed water mainly point to the area outside the depressed zone of the lane; the sewage pump matched with the lane comprises a water suction head matched with the sunken belt and the like.

According to a third aspect of the invention, the urban dust cleaning system comprises a purification system for urban fugitive dust and/or a motor vehicle washing system. The invention aims to purify the urban raise dust and clean the motor vehicles, and the invention does not limit the urban raise dust purification system and the motor vehicle cleaning system.

In a specific embodiment, the urban raise dust purification system comprises a raise dust capture device, and the urban raise dust purification system further comprises motor vehicles and/or urban roads, wherein the raise dust capture device is arranged on the motor vehicles and/or the urban roads, the raise dust capture device and the arrangement of the raise dust capture device on the motor vehicles and/or the urban roads meet the normal use requirements of the motor vehicles and/or the urban roads, and at least part of the raise dust in the urban areas is captured by the raise dust capture device.

According to the present invention, the dust capturing device is not particularly limited, including its configuration and arrangement, on the premise that it can be installed on the motor vehicle and/or urban road and can capture urban dust. For example, it may be, but is not limited to: the raised dust capturing device is a dust collector; or the raised dust capturing device is a device comprising a dust suction body, a cavity and at least one air guide body, wherein the dust suction body, the cavity and the air guide body are arranged, an air flow flows through the cavity under the guidance of the air guide body, and the air flow is in contact with the dust suction body; or the raised dust capturing device is an electric dust removing device; or the flying dust capturing device is a combination of two or more selected from the flying dust capturing devices. Wherein the dust-absorbing body contains or does not contain a support body; the air flow flows through the cavity under the guidance of the air guide body, and comprises air flowing through the air guide body and flowing out of or into the cavity; the air flow contacts the dust-absorbing body in at least one stage before, after or simultaneously with flowing out or into the cavity.

According to the present invention, the smallest unit of the dust collection body in the dust capture device is referred to as a unit dust collection body. A dust collector in a dust collecting device can be composed of a single dust collector or a plurality of dust collectors. A dust collection body including a plurality of unit dust collection bodies is called a combined dust collection body, and the unit dust collection bodies in the combined dust collection body may be the same or different.

In the invention, the dust collector is selected from one or more of any rigid medium and flexible medium with the function of standing and raising dust and manufactured products comprising the rigid medium and the flexible medium. The retention function comprises one or more of functions of adsorption, adhesion and interception of the dust collector body to the raised dust.

The rigid medium with the standing dust raising function refers to a substance which can be used as a dust collector and does not deform during storage and use and a finished product containing the substance.

Wherein, the adsorbent is a porous substance with large specific surface. For example, one or more of activated carbon, activated alumina, silica-alumina, aluminosilicates (including natural or synthetic molecular sieves). The dust-binding agent comprises water, synthetic and natural materials which have viscosity and can be matched with the rigid medium or the flexible medium, and preparations containing synthetic and natural materials which have viscosity and can be matched with the rigid medium or the flexible medium, such as aqueous solution and the like. They are commercially available or can be prepared by any of the known techniques as desired.

When the rigid and/or flexible medium with the function of standing and raising dust is limited to be directly used as a dust collector or the rigid and/or flexible medium with the function of standing and raising dust is required to be arranged on the non-wheel track belt of the motor vehicle or the motor vehicle lane in a non-direct contact manner, the dust collector comprises a support body. The function of the support body comprises supporting, loading or loading the rigid and/or flexible medium with the function of retaining the raise dust, so that the medium is suitable for being used as a dust suction body of the raise dust capture device. Through different designs of the supporting body, the dust collector can be changed in structure to meet different use requirements. Wherein the support may be any rigid and/or flexible body that meets the requirements of the present invention.

According to the invention, the rigid support is of a type which does not deform during storage and use. One-dimensional, two-dimensional and three-dimensional supports can be distinguished. Wherein the one-dimensional support is (x) ₂ -x ₁ )、(y ₂ -y ₁ ) And (z) ₂ -z ₁ ) One of the values of (a) is much larger than the other two, which are the same or different; the two-dimensional support means (x) ₂ -x ₁ )、(y ₂ -y ₁ ) And (z) ₂ -z ₁ ) One of the values of (a) is much smaller than the other two, which are the same or different; the three-dimensional support means (x) ₂ -x ₁ )、(y ₂ -y ₁ ) And (z) ₂ -z ₁ ) Are the same or different. Wherein, far greater means that the multiple between the values compared is more than 10 times, such as 10-100 times; by different is meant that the multiple between the values compared is from greater than 1 to less than 10 times. x is the number of ₁ 、y ₁ 、z ₁ Corresponding minimum values of the support body projection (orthographic projection) on an x axis, a y axis and a z axis respectively; x is the number of ₂ 、y ₂ 、z ₂ The maximum values of the support projection (orthographic projection) on the x-axis, the y-axis and the z-axis are respectively.

In the invention, when the urban raise dust purification system comprises a lane, the outer non-wheel-track belt comprises the areas occupied by a traffic island, a road shoulder, road teeth (comprising curb stones and curbstone) and an isolation belt.

According to a third aspect of the invention, the urban raise dust purification system is present for the purpose of capturing and removing raised dust haze, which is beneficial for reducing the spread of raise dust in urban areas.

In one embodiment, the vehicle washing system comprises a first washing area and an optional second washing area, wherein the first washing area comprises a waterway, a waterway water supply unit and a waterway drainage unit, the waterway water supply unit and the waterway drainage unit are arranged and controlled, so that when a vehicle passes through the waterway, water in the waterway can be stirred and/or splashed, the stirred and/or splashed water enables at least part of a vehicle including a vehicle chassis to be washed, and the water falling back after washing flows at least partially in the opposite direction of the vehicle running.

In the invention, the fact that at least part of the backwashed water flows in the water channel in the opposite direction of the running direction of the motor vehicle means that the mixing (also called back mixing) of the backwashed water and the water in the water channel along the running direction of the motor vehicle is inhibited or eliminated through the arrangement and control of the water channel, the water channel water supply unit and the water channel water discharge unit. Thus, any solution that adequately suppresses or eliminates such mixing by design of the waterway, water supply unit, and water discharge unit, etc., should be understood to fall within the scope of the present invention for flow in the opposite direction of vehicle travel in the waterway.

In discussing the waterway, the longitudinal direction refers to a direction parallel to a direction of travel of the vehicle, and the transverse direction refers to a direction perpendicular to the direction of travel of the vehicle. The upstream direction refers to a direction in which the motor vehicle travels in a waterway. When the position comparison is carried out, the position close to the former position is the upstream position according to the driving direction of the motor vehicle, and the position is the downstream position on the contrary. And according to the transverse direction, the bottom surface of the water channel comprises a water channel wheel track belt and a water channel non-wheel track belt. Wherein, limited by the water course, the part that the wheel can be rolled when the motor vehicle passes through the water course is called as the water course wheel track belt; the part of the motor vehicle wheel which can not be rolled is called a water channel non-wheel-track belt. Typically, the transverse central portion of the channel floor is a channel non-tracking strip flanked on either side by channel tracking strips, optionally including a channel non-tracking strip on the outer side of each channel tracking strip. The plane refers to a plane without an inclination angle (the inclination angle is 0) with the horizontal plane, and the bottom surface of the water channel is a plane which refers to the bottom surface of the water channel with a water channel wheel track belt and a water channel non-wheel track belt on the same plane; the inclined plane is a slope surface with an inclination angle of more than 0 degree with the horizontal plane, and the bottom surface of the water channel is an inclined plane and refers to the bottom surface of the water channel with a water channel wheel track belt and a water channel non-wheel track belt on the same inclined plane; the curved bottom surface of the water channel means any form of the bottom surface of the water channel which can meet the requirements of the water channel except the plane and the inclined plane. For example, the bottom surface of the water channel may be a curved surface with a transverse undulation; can be a curved surface with longitudinal fluctuation; or a curved surface that varies both laterally and longitudinally. In these variations, the channel-wheel-track and channel-non-wheel-track bands in the channel floor may or may not be synchronized.

The arrangement of the waterway, the water supply unit and the water discharge unit can be changed on the premise that the motor vehicle can pass through the waterway, the water in the waterway can be stirred and/or splashed, the stirred and/or splashed water can wash at least part of the motor vehicle including the chassis of the motor vehicle, and the water falling back after washing at least part of the water flows in the opposite direction of the running of the motor vehicle in the waterway. The arrangement of the water channel comprises the step of arranging the bottom surface of the water channel into a plane, an inclined plane or a curved surface or the combination of two or more than two of the plane, the inclined plane and the curved surface; the water supply unit comprises a water supply port provided with a water channel, the water channel can be provided with the water supply port at one or more positions according to requirements, and the position of the water supply port can be the bottom, two sides, the upper side or any combination of the two; the arrangement of the water channel drainage unit comprises a drainage port for arranging the water channel, and the drainage port can be arranged at one or more positions of the water channel according to requirements, and the arrangement position of the drainage port can be the bottom, two sides or the combination of the bottom and two sides of the water channel.

For example, they may be, but are not limited to:

in one embodiment, the bottom surface of the waterway is a flat surface, and the waterway water supply opening and the waterway water discharge opening are arranged so that when the water supply unit supplies water and the water discharge unit discharges water, the water forms a head difference (also called a water head) in the waterway, and the head difference enables the water to flow in the waterway against the direction of travel of the motor vehicle. For example, a water outlet is arranged at or near the starting end of the water channel, a water supply inlet is arranged at the upstream of the water outlet, such as at or near the tail end of the water channel, when the water supply inlet supplies water to the water channel, the water entering the water channel flows in the water channel against the driving direction of the motor vehicle, and the water quantity in the water channel is controlled and maintained to meet the requirement through the water outlet, so that when the motor vehicle passes through the water channel, the water in the water channel is stirred and/or splashed under the rolling belt of the wheels of the motor vehicle, at least part of the vehicle body including the chassis of the motor vehicle is washed in the stirred and/or splashed water, and simultaneously, the water returning to the water channel flows in the opposite direction of the driving of the motor vehicle under the driving of the water flowing in the direction against the driving direction of the motor vehicle.

When part of water entering the reflux groove flows back to the water channel through the lateral opening of the reflux groove, the rest part of water is discharged out of the water channel through the water outlet. On the premise, the design and the structure of the reflux groove can be flexibly designed. For example, the return channel is a pre-fabricated channel that can be disposed on the floor of the waterway.

In the technical scheme, the backflow groove can realize that at least part of the fallen water flows along the reverse direction of the running of the motor vehicle. Therefore, the present invention is not limited to the positions of the water supply opening and the water discharge opening in the waterway, and the like, on the premise that the water storage amount in the waterway satisfies the requirement by controlling the water supply amount of the water supply opening and the water discharge amount of the water discharge opening.

In one embodiment, the bottom surface of the water channel is a slope, and the slope is designed to enable at least part of water in the water channel, which falls back after washing, to flow in the reverse direction of the motor vehicle running in the water channel; preferably, the inclined plane extends and rises along the running direction of the motor vehicle, and the inclination angle of the inclined plane is more than 0 degree and less than or equal to 45 degrees; preferably 2 ° to 35 ° or less.

In the technical scheme, a plurality of water supply ports and water discharge ports can be arranged in the water channel, and the water storage quantity in the water channel can meet the requirement by the combined use of the water supply ports and the water discharge ports and the control of the water supply quantity of the water supply ports and the water discharge quantity of the water discharge ports.

In one embodiment, the bottom surface of the water channel is an inclined plane, the inclined plane extends and rises along the driving direction of the motor vehicle, and the inclination angle of the inclined plane is greater than 0 degree and less than or equal to 45 degrees; preferably 2 ° to 35 ° or less. A backflow groove is detachably arranged at the position of the water channel non-wheel track belt on the bottom surface, and the backflow groove is arranged so that at least part of water falling back after flushing enters the backflow groove, and optionally: (1) The downstream notch of the reflux groove is communicated with the water outlet, and water entering the reflux groove flows along the reverse direction of the running of the motor vehicle and is discharged out of the water channel through the water outlet; (2) Or the downstream notch of the backflow groove is communicated or not communicated with the water outlet, the two lateral sides of the backflow groove respectively comprise openings, and the openings are arranged to enable the water entering the backflow groove to partially or completely return to the water channel where the water channel wheel track belt is located through the openings in the original position or the reverse flow along the running direction of the motor vehicle. When part of water entering the reflux groove flows back to the water channel through the lateral opening of the reflux groove, the rest part of water can be discharged out of the water channel through the water outlet. On the premise, the design and the structure of the reflux groove can be flexibly designed. For example, the return channel is a pre-fabricated channel that can be disposed on the floor of the waterway.

In the technical scheme, the existence of the inclined plane and the backflow groove can realize that at least part of the fallen water flows along the reverse direction of the running of the motor vehicle. Therefore, a plurality of water supply ports and water discharge ports can be provided in the waterway, and the water supply amount to the water supply ports and the water discharge amount from the water discharge ports can be controlled by using the water supply ports and the water discharge ports in combination, so that the water storage amount in the waterway can meet the requirement.

In one embodiment, the bottom surface of the waterway is a curved surface, and the water flowing back after washing in the waterway is at least partially flowed in the reverse direction of the running of the motor vehicle by arranging the curved bottom surface and the water supply opening of the water supply unit and the water discharge opening of the water discharge unit and controlling the water supply amount of the water supply opening and the water discharge amount of the water discharge opening.

For example, but not limited to, the bottom surface of the waterway may be designed to:

the water channel wheel track belt and the water channel non-wheel track belt are bottom surfaces which are not on the same plane, wherein the water channel non-wheel track belt is higher than the water channel wheel track belt, the longitudinal direction of the water channel non-wheel track belt at least comprises a backflow groove, and the backflow groove is designed to enable at least part of water falling back after washing to enter the backflow groove, optionally: (1) The downstream notch of the reflux groove is communicated with the water outlet, and water entering the reflux groove flows along the reverse direction of the running of the motor vehicle and is discharged out of the water channel through the water outlet; (2) Or the downstream notch of the reflux groove is communicated or not communicated with the water outlet, the two lateral sides of the reflux groove respectively comprise an opening, the water entering the reflux groove partially or completely returns to the water channel where the water channel wheel track belt is located through the opening in the original position or in the reverse flow along the running direction of the motor vehicle, and when part of water entering the reflux groove returns to the water channel through the lateral opening of the reflux groove, the rest part of water is discharged out of the water channel through the water outlet. On the premise, the design and the structure of the reflux groove can be flexibly designed. For example, the backflow groove is a prefabricated groove which can be arranged on the bottom surface of the water channel. Here, the portion of the bottom surface of the water channel non-wheel-track belt that is higher than the bottom surface of the water channel wheel-track belt is not particularly limited on the premise that the passing of the motor vehicle is satisfied and the fallen water flows in the reverse direction of the motor vehicle traveling in the return water tank.

Or the bottom surface of the water channel wheel track belt is a concave curved surface, and the bottom surface of the water channel non-wheel track belt is a plane or a concave curved surface, wherein the high point of the bottom surface of the water channel wheel track belt with the concave curved surface is equal to or higher than the high point of the water channel non-wheel track belt with the plane or the concave curved surface, the longitudinal direction of the bottom surface of the water channel non-wheel track belt at least comprises a backflow groove, and the backflow groove is designed to ensure that at least part of water falling back after flushing enters the backflow groove and flows along the reverse direction of the running of the motor vehicle. When the height of the bottom surface of the concave curved water channel wheel track belt is higher than that of the flat or concave curved water channel non-wheel track belt, on the premise that the motor vehicle passes through and the fallen water flows in the backflow groove in the reverse direction of the motor vehicle, the part of the bottom surface of the water channel wheel track belt, which is higher than the bottom surface of the water channel non-wheel track belt, is not particularly limited.

In one embodiment, the bottom surface of the water course is a combination of two or more selected from the group consisting of a flat surface, an inclined surface, and a curved bottom surface. The arrangement of the bottom surface of the water channel, the water supply opening of the water supply unit and the water discharge opening of the water discharge unit, and the control of the water supply amount of the water supply opening and the water discharge amount of the water discharge opening can enable water falling back after flushing in the water channel to flow at least partially in the reverse direction of the running direction of the motor vehicle.

In the above embodiments, the water supply inlet of the waterway can be arranged at the bottom (including the waterway wheel trace belt and waterway non-wheel trace belt part on the bottom surface), above, at two sides, or any combination thereof; the drain openings may be located at the bottom (including the bottom portion of the waterway-raceway belt and the waterway non-raceway belt) and on both sides of the waterway, or a combination thereof.

In the invention, the water channels arranged in sections are the water channel combination of a plurality of independently arranged water channels (also called sub-water channels) which are connected in series for use in the first cleaning area. In the combination of the water channels, the bottom surfaces of the water channels which are independently arranged can be the same or different. The water supply unit and the water discharge unit may be provided separately or in common.

Generally, for the channels which are arranged in sections and are close to each other or spaced apart from each other, a series connection mode is adopted, that is, a water supply opening of the channel at the downstream position is connected with a water discharge opening of the channel at the upstream position by using a water guide pipe, and water in the channel is introduced from one channel to another channel through the water guide pipe. For the sectionally arranged water channels close to each other, optionally, a water overflow groove is arranged between the water channels, and the water channels and the water overflow groove are arranged to enable water in the water channels to overflow from one section of water channel to the other section of water channel along the opposite direction of the running of the motor vehicle through the overflow groove.

According to the invention, the process of the motor vehicle driving through the waterway, the wheels agitating and/or splashing the water in the waterway, and causing at least a portion of the motor vehicle including the chassis to be washed, is a dynamic process. Therefore, the environment in which the waterway is disposed must meet this requirement.

The present invention is applicable to the arrangement of the waterway depending on a specific use environment or the like, on the premise that the water is sufficiently retained in an amount sufficient to cause agitation and/or splashing to occur at least partially under a rolling belt of a wheel of a driven vehicle, the water causing the agitation and/or splashing to occur causing at least a part of a vehicle body including the wheel to be washed. Generally, environments suitable for deploying the vehicle washing system of the present invention include, but are not limited to, driveways, parking lots, square spaces accessible by vehicles, and spaces inside or outside buildings that can meet the requirements. The water course may be, but is not limited to, formed by means of excavation and/or coffering on the site where the water course is arranged, such as a motorway; may be, but is not limited to, a site where the waterway is disposed, such as a parking lot or a building, is constructed as designed in the construction work; but also but not limited to, assembly from prefabricated members on the site where the waterway is arranged, etc. In particular implementations, where desired, channel construction includes the use of existing techniques for water seepage control of the channel.

The present invention provides that the waterway in the vehicle washing system may be a straight waterway, a curved waterway, an annular (including closed or not) waterway, or any combination thereof, depending on the site. The water channel can be a through whole body or a combination of water channels arranged in sections. Based on the characteristics of the water channel, the invention does not specially limit the length, width and the like of the water channel on the premise of meeting the requirement that motor vehicles can pass through and cleaning at least part of the vehicle bodies including motor vehicle chassis.

Generally, the shortest length for an independently disposed non-circular water channel may be, but is not limited to, more than 2 meters, preferably more than 20 meters, and more preferably more than 40 meters; the longest may be, but is not limited to, 2000 meters or less, preferably 1000 meters or less. The radius of the annular water channel may be, but is not limited to, greater than the minimum turning diameter of the vehicle, for example, the radius of the annular water channel may be, but is not limited to, greater than 2L meters, where L is the body length of the motor vehicle body (in an implementation, the radius may be calculated based on the vehicle with the longest body in the parked vehicle); for an irregular closed waterway (an end-to-end waterway), the turning radius of the curve therein should be, but not limited to, greater than or equal to the turning radius of the vehicle to which the vehicle washing system including the waterway is primarily directed.

Typically, the width of the waterway matches the width of the body of the motor vehicle, and the width of the waterway should include the waterway non-wheeling belt when the waterway wheeling belt outside the bottom surface of the waterway includes the waterway non-wheeling belt.

According to the invention, after the wheels of the running vehicle agitate and/or splash water at least partially washes the vehicle, including the chassis, the water falling back into the flume mixes with the water in the flume in the opposite direction of vehicle travel. The invention provides the system with the characteristic that the water for washing the motor vehicle tends to be clear along the driving direction of the motor vehicle, thereby ensuring the cleaning quality of the motor vehicle.

According to the invention, the bottom surface of the water channel (comprising the water channel wheel track belt, the water channel non-wheel track belt and the backflow groove) is provided with grooves along the longitudinal direction and/or the transverse direction. The recess can be designed flexibly, if desired. For example, the longitudinal grooves may be of an integral design of a through water channel or a segmented and multi-segment design, and one or more longitudinal grooves may be provided as required; similarly, the transverse grooves can be of an integral design penetrating the cross section of the water channel, or of a segmented design between water channel wheel track belts and/or water channel non-wheel track belts, and the transverse grooves can be one or more.

When the bottom surface of the water channel is longitudinally provided with the groove, the bottom surface of the groove bottom of the groove can be an inclined plane, for example, the inclined plane extends along the running direction of a motor vehicle, and the inclination angle is more than 0 degree and less than or equal to 45 degrees; more preferably, the inclination is 2 ° to 35 ° or less; when the bottom surface of the water channel is an inclined surface, the inclined angle of the inclined surface of the bottom surface of the groove bottom is preferably equal to or greater than the inclined angle of the bottom surface of the water channel.

The invention does not limit the pattern of the grooves included on the bottom surface of the waterway, while ensuring that the passage of the motor vehicle is not affected. Generally, when the tread band comprises grooves, the width of the grooves should be less than the width of the tyres of the wheels of the motor vehicle, in order not to affect the passage of the motor vehicle; preferably, the width of the groove is less than or equal to one half of the width of a wheel of the motor vehicle; it is further preferred that the width of the groove is 30mm to 100mm. When the non-tracking tape includes a groove, the allowable width of the groove is limited mainly by the available space of the non-tracking tape.

Alternatively, the groove may be embedded with a prefabricated rigid structure having a groove function, for example a prefabricated metal groove adapted to the groove, to reduce and minimize damage to the road surface that may be caused by the driving of the vehicle.

If necessary, a water supply port and/or a water discharge port may be provided at the groove (including a port and/or a non-port of the groove).

The inventors have found that when the bottom surface of the waterway includes the grooves in the longitudinal and/or transverse directions, the convenience of using the waterway may include at least the following: (1) The collection and the removal of the sedimentary pollutants in the water channel are facilitated; (2) On the premise of keeping a lower water level in the water channel, the water retention amount in the water channel can be increased.

According to the invention, optionally, a filter body is arranged at the return channel and/or the groove. The filter body serves to purify the water after washing the vehicle body, so that, on the premise of meeting this object, various materials which can be used for filtration or percolation can be used for preparing the filter body of the present invention. For example, the filter material is filter cloth which can be embedded on the backflow groove and/or the groove in a manner of convenient assembly and disassembly; the filter material is filler with a filtering function, and the filler can be filled into the backflow groove and/or the groove in a filling mode for use.

The inventor finds that: (1) For the water channel wheel trace belt which is lower than the water channel non-wheel trace belt, the water channel non-wheel trace belt comprises a backflow groove, or the water channel wheel trace belt and the water channel non-wheel trace belt are in the same plane, the water channel non-wheel trace belt is detachably provided with a backflow groove which is higher than the water channel wheel trace belt, the backflow grooves in the water channel wheel trace belt and the water channel non-wheel trace belt respectively comprise grooves along the longitudinal direction, the longitudinal grooves are communicated with the bottom surface of the water channel through the transverse grooves, and water entering the backflow groove can flow back to a downstream water channel where the water channel wheel trace belt is located through the in-situ or downstream transverse grooves. (2) For the water channel wheel track belt is lower than the water channel non-wheel track belt, the water channel non-wheel track belt comprises a backflow groove, or the water channel wheel track belt and the water channel non-wheel track belt are in the same plane, the water channel non-wheel track belt is detachably provided with a backflow groove higher than the water channel wheel track belt, the backflow grooves in the water channel wheel track belt and the water channel non-wheel track belt respectively comprise a groove along the longitudinal direction, the water channel non-wheel track belt is provided with a water diversion pipeline which is parallel to and communicated with the groove (for example, a water diversion pipeline which is arranged below the bottom surface of the backflow groove and is longitudinally arranged on the same horizontal plane with the bottom surface of the groove in the backflow groove), the water diversion pipeline is communicated with the longitudinal groove in the water channel wheel track belt through the water diversion pipeline or the groove arranged transversely, and water entering the backflow groove can flow back to the position of the water channel where the designated water channel wheel track belt is located through the water diversion pipeline.

With respect to the design of the water channels, including but not limited to these aspects, it is advantageous to increase the efficiency of water usage while ensuring a cleaning effect. The water channel itself may effect a water purification in the water channel, in particular when filter bodies are provided in the longitudinal grooves and optionally in the transverse grooves.

According to the present invention, the water supply unit may supply water to the waterway through the water supply port using any water supply method of the related art. For example, the water supply port of the water channel can be connected to a public water supply system for water supply or water supplement; and water is supplied or supplemented to the water channel by a water vehicle in a motorized way. Generally, the system is provided with a water supply unit, including one or a combination of more than two of a pool, a water tank, a water tower and a water pump which are configured to supply water to a water channel. According to the actual requirement, the water supply unit of the water channel can be provided with one or more water supply points comprising a water pool, a water tank, a water tower or a water pump, and the like, and each water supply point can supply water to the water channel through one or more water supply ports.

According to the invention, the drainage unit can drain water through the drainage outlet by adopting any drainage method in the prior art, and maintains the balance of water supply and drainage in the water channel together with the water supply unit, so that the water in the water channel meets the requirement of the system on the water quantity remained in the water channel. For example, the position of the water channel is higher than the surrounding environment, and water can be drained by arranging water outlets (also called natural water outlets) at the bottom or two sides of the water channel and flowing out of the water channel by means of the gravity of the water; or the position of the water channel is lower than or equal to the surrounding environment, water outlets are arranged at the bottom or two sides of the water channel, and water is drained by a drainage pump connected with the water outlets; or the water channels are arranged in sections, each section is provided with a water supply port and a water discharge port, the water discharge at the upstream of the water channels is connected with the water supply port at the downstream among the water channels arranged in sections, and if necessary, a drainage pump is arranged among the connecting pipelines, so that the water at the upstream flows into the water channels at the downstream through the pipelines. In addition to the water passage having its own water purification function, generally, at least one water discharge port of the water passage may be provided with a water pump, and water discharge and discharge control may be performed to the outside of the water passage by the water pump.

In the invention, the water supply port of the water channel can be arranged at the bottom, two sides, above or any combination thereof of the water channel; the meaning of arranging the water outlet at the bottom, both sides or a combination thereof of the water channel includes that the water supply mode of the water channel through the water supply port and the water discharge mode of the water channel through the water outlet are not limited on the premise of not influencing the traffic of the motor vehicle and meeting the requirement of the water channel on the water quantity, and meeting the requirement that the flow direction of water in the water channel is controlled through the design of water supply and water discharge so as to eliminate or partially eliminate the mixing of return water along the driving direction of the motor vehicle. For example, in a specific implementation, may be, but is not limited to:

the water supply ports of the water channel are arranged at the bottom and/or two sides of the water channel, a control switch and a spray head of water can be directly added at the water supply ports, the spray head is controlled by the control switch to supply water or supplement water to the water channel from the bottom and/or the side direction of the water channel, or the water supply ports are directly connected with an upstream water outlet as overflow ports of the water, so that the water in the upstream water channel overflows to a downstream water channel; the water channel water supply port is arranged above the water channel, a control switch and a spray head of water can be directly added at the water supply port, and the spray head is controlled by the control switch to supply water or supplement water to the water channel from the upper part of the water channel. If necessary, the water channel can be provided with one or more water supply ports, and each water supply port can be provided with one or more control switches and spray heads as described above. When the water channel is provided with a plurality of water supply ports, the water supply of at least one water supply port is preferably clear water. The clear water refers to clear water from outside the water course or purified water from the water course. The water supplied from the other water supply port may be water overflowing directly from the upstream to the downstream or water discharged from the upstream water discharge port, for example, when the water passage is divided into sections, the upstream water passage water discharge port may be connected to the downstream water passage water supply port through a water guide pipe, so that the water in the upstream water passage is introduced into the downstream water passage through the water guide pipe. If desired, a drain pump may be provided between the upstream drain opening and the downstream water supply opening to accomplish this. Generally, the fresh water supply port is preferably disposed at or near an end of the waterway in a direction of travel of the vehicle.

When the water supply ports are one or more groups of spray heads arranged on two sides and/or above the water channel, the arrangement of the spray heads and the water pressure transmitted to the spray heads enable water to supply water to the water channel in a spraying mode. When the water is supplied by adopting the mode and is directly sprayed to the body of the motor vehicle, other parts of the motor vehicle can be cleaned.

The water channel outlet can be arranged at the bottom and/or two sides of the water channel and comprises a control switch for adding water at the water outlet, a water drain pipe, a water drain pump and the like. When the drainage outlet is provided with a drainage pump, a filter can be selectively arranged to be matched with the water pump for use. Therefore, pollutants formed in the water channel in the using process, such as deposited solid particles like mud and sand, can be removed and reduced, and the water purified in the way can be directly circulated into the water channel and also can be circulated to the water supply unit for recycling.

The control of the water supply and drainage can be achieved by any of the existing techniques, provided that the control of the water supply and drainage is sufficiently achieved for the water supply inlet and the water discharge outlet. For example, water supply from a water supply port and water discharge from a water discharge port are controlled by manpower; the water level and the motor vehicle are judged and recognized by sensors, such as a water level sensor, a moving object sensing device, and the like, and a water supply pump and a water discharge pump are controlled accordingly, and the like.

According to the invention, the water channel comprises refractors for arranging water, and the direction of secondary splashing of water stirred and/or splashed by the motor vehicle wheels can be further adjusted and controlled through the arrangement of the water refractors, so that the secondary splashing water is at least partially splashed to the vehicle body or a specific direction, the efficiency of flushing the vehicle body is improved, and the like. The invention has no restriction on the structural style of the water-refracting body and the position of arrangement in the system, provided that it is sufficient to fulfill the function.

Optionally, the first washing zone is provided with a water purification unit. The water purification unit comprises a filter, a water sedimentation tank and the like which are matched with the water pump.

According to the invention, the system comprises a shielding unit arranged in the water channel. The shielding unit functions include but are not limited to: (1) Preventing or inhibiting water spillage that may result from, including, wheel agitation and/or splashing; (2) Prevent or inhibit the pollution of sand and dust to the water course, insulate heat or preserve heat.

The shielding unit may be an open water dam when the primary purpose is to prevent or inhibit water spillage that may be caused by agitation and/or sputtering, including the wheels. The invention allows for flexible design of the water dam body design, including prevention or suppression of water spillage that may result from, for example, wheel agitation and/or splashing. For example, water baffles or the like are provided along both sides of the waterway. When the water channel is provided with the water baffle, the water baffle can have a water retaining function and also has the function of the water refractor by designing and endowing the water baffle with a certain function of the water refractor.

The shielding unit may be a closed passage allowing a vehicle to enter and exit when the main purpose is to prevent or suppress contamination of a waterway with dust, heat insulation, or heat preservation. When the water channel and the shielding unit are combined by adopting prefabricated components, the components of the water channel and the shielding unit can be designed integrally without limitation.

The invention is not particularly limited to water introduced into the waterway, provided that it is sufficient to meet motor vehicle cleaning requirements and does not leave significant residual stains and contamination on the vehicle body. For example, clarified rainwater, river water, reclaimed water, and tap water from public water supplies, and in special cases, deionized water obtained by ion exchange, and the like. In special weather conditions, such as the northern winter season, and when the system is used in the open air, the water may contain antifreeze additives and the like.

According to the invention, any auxiliary unit which does not affect or contribute to the operation of the motor vehicle washing system may optionally be included. For example, a transitional connection is arranged at the position where the motor vehicle enters or exits the waterway so as to buffer or reduce vibration and jolt which can be generated when the motor vehicle passes through the waterway; the extension of the water channel can also be arranged at the end of the water channel, i.e. when the motor vehicle moves away from the water channel, the extension of the water channel comprises a water absorption body, and the water absorption body is arranged so that when the motor vehicle passes through the extension, the wheels of the motor vehicle can be at least partially rolled to the water absorption body, thereby at least partially wiping off the water attached to the motor vehicle, including the wheels. When the system comprises the water channel extending part, the water absorbing bodies can be integrally arranged to be the width of the water channel extending part or the width of the water channel extending part is matched with the width of the body of the motor vehicle, and the water absorbing bodies can also be arranged to be two parallel water absorbing bodies, the width of each water absorbing body is matched with the width of a wheel of the passing vehicle, and the distance between the two parallel water absorbing bodies is matched with the wheel distance of the motor vehicle.

fig. 12-a shows water 121, channel band 122a forming the bottom surface of the channel, and channel non-band 123a. In fig. 12-a, the bottom surface (cross-sectional contour line) of the waterway, which is constituted by the waterway-wheel trace strip 12a and the waterway non-wheel trace strip 123a, is a straight line.

Fig. 12-b shows water 121, channel band 122b forming the bottom surface of the channel, and channel non-band 123b. In fig. 12-b, the channel non-tracking strip 123b includes a protrusion 125b, and the bottom surface (cross-sectional contour) of the channel formed by the channel tracking strip 122b and the channel non-tracking strip 123b is a curved line (i.e., the cross-sectional contours of the channel tracking strip and the channel non-tracking strip formed on different surfaces, the same applies below).

Fig. 12-c includes water 121, channel band 122c forming the bottom surface of the channel, and channel non-band 123c. In fig. 12-c, the water course non-tracking strip 123c includes a protrusion 125c, and the protrusion 125c includes a V-shaped recess in the middle, which is a backflow groove 126 longitudinally formed at the protrusion 125 c. In fig. 12-c, the bottom surface (cross-sectional contour) of the channel, which is formed by the channel band 122c and the channel non-band 123c, is a curved line.

Fig. 12-d illustrates water 121, channel band 122d forming the bottom surface of the channel, and channel non-band 123d. In fig. 12-d, each of the two water channel wheel-trace strips 122d forming the bottom surface of the water channel includes a U-shaped depression, the protrusion 125d of the water channel non-wheel-trace strip 123d forming the bottom surface of the water channel includes a V-shaped backflow groove 126, the V-shaped backflow groove 126 includes a U-shaped depression, and 3U-shaped depressions distributed in the water channel wheel-trace strips and the water channel non-wheel-trace strips are longitudinal grooves 127 longitudinally disposed in the wheel-trace strips and the V-shaped backflow grooves. In fig. 12-d, the bottom surface (cross-sectional contour) of the channel formed by the channel band 122d and the channel non-band 123d is a curved line.

Fig. 12-e include water 121, channel band 122e, channel band 123e, and channel band 124e, which form the bottom of the channel. Unlike fig. 12-d, both sides of the waterway include waterway non-tracking strips 124e, waterway non-tracking strips 124e include a projection 128, and projection 128 includes longitudinal grooves 127.

It should be understood that the dimensions and pattern of the longitudinal grooves 127 included in the flume and flume non-wheel tracks and in the various flume non-wheel tracks may be the same or different in the various figures.

Fig. 13-a, 13-b, 13-c and 13-d show schematic longitudinal cross-sectional views of several channel floors with the cross-section of fig. 12-a, wherein:

fig. 13-a includes water 121 and a waterway bottom 131. In fig. 13-a, the waterway bottom 131 (cross-sectional contour line) is a horizontal straight line.

The bottom surface of the waterway is planar as determined by fig. 12-a and 13-a.

As mentioned above, the water channel with a plane bottom surface can be provided with a water supply port at least at the upstream of the water channel, such as at the end of the water channel or near the end, and a water discharge port at the downstream of the water channel, such as at the beginning of the water channel or near the beginning, and a water head flowing against the driving direction of the motor vehicle is formed in the water channel by the water supply of the water supply port, when the motor vehicle drives through the water channel, the water 121 in the water channel is stirred and/or splashed under the action of the wheels of the motor vehicle, so that at least part of the vehicle body including the wheels is washed in the stirred and/or splashed water, and the water falling back into the water channel is not mixed back along the driving direction of the motor vehicle.

Fig. 13-b illustrates a channel floor 132 including water and a slope at an angle a (also referred to as slope angle) to the horizontal. In fig. 13-b, the sloping flume floor 132 (cross-sectional outline) is a sloping line.

The bottom surface of the waterway as determined by fig. 12-a and 13-b is sloped.

Fig. 13-c includes water 121, and a curved flume floor 133 that forms the flume floor. In fig. 13-c, the curved flume floor 133 (cross-sectional contour) is a continuously undulating curve.

The bottom surface of the waterway as determined by fig. 12-a and 13-c is a curved surface with longitudinal, continuous undulation.

Fig. 13-d includes water 121, a curved waterway bottom surface 134 that forms the waterway bottom surface, and a transitional planar waterway bottom surface 135. In fig. 13-d, the curved flume floor 134 and the transitional planar flume floor 135 (cross-sectional contour) are shown as a longitudinal, discontinuous undulating line.

The bottom surface of the channel defined by figures 12-a and 13-d is a longitudinal, discontinuous undulating surface including a transitional flat surface between the surfaces.

When the water channel is a curved surface which is longitudinally and discontinuously fluctuated, the water in the water channel forms slow flow at the transitional plane water channel and flows to the water channel of the other fluctuated section in the opposite direction of the running of the motor vehicle in an overflow mode. Optionally, the transitional planar raceway is configured with a water supply and/or drain everywhere.

Fig. 13-b, 13-c and 13-d show three examples of the suppression of back mixing of water falling back into the waterway in the direction of travel of the vehicle, achieved by different designs of the bottom surface of the waterway.

In the solution shown in fig. 13-b, the inclined waterway bottom surface 132 is raised along the driving direction of the vehicle, when the vehicle is driven into the waterway, the water 121 in the waterway is agitated and/or splashed by the wheels of the vehicle, so that at least part of the vehicle body including the wheels is washed in the agitated and/or splashed water. The water which is stirred and/or splashed and washes the vehicle body falls back into the trough and flows against the direction of travel of the vehicle, as determined by the sloping flume floor 132 which rises in the direction of travel of the vehicle. Compared with other technical schemes, the technical scheme does not specially limit the position of the water supply opening.

In the solution shown in fig. 13-c, the curved waterway bottom 133 is in a form of a rise, a fall, a rise, and a fall along the driving direction of the vehicle. In specific implementation, the peak height of each corrugation can be designed to be the same or different. The system can be used for arranging a water supply port at least at the upstream of the water channel, such as the tail end or the close end of the water channel, arranging a water discharge port at the downstream of the water channel, such as the starting end or the close end of the water channel, forming a water head flowing against the driving direction of the motor vehicle in the water channel through the water supply port, and stirring and/or splashing the water 121 in the water channel under the action of the wheels of the motor vehicle when the motor vehicle drives through the water channel, so that at least part of the vehicle body including the wheels is washed by the stirred and/or splashed water, and the water falling back into the water channel is not mixed back along the driving direction of the motor vehicle.

The solution according to fig. 13-d differs from the solution according to fig. 13-c in that there is a horizontal connection of the groove bottoms between the corrugations. The presence of the connection makes it possible to provide a relatively deep water zone in the water channel, which is advantageous for adjusting and changing the washing pattern of the motor vehicle when passing through the water channel. For example, the vehicle may be cleaned in agitated water in relatively deep water regions and in splash water in corrugated regions.

Fig. 13-c and 13-d illustrate the technical solution that when the water channel is arranged on a horizontal ground (such as a horizontal road surface), the bottom surface of the water channel acts as an inclined surface rising along the driving direction of the motor vehicle, each section of the bottom surface of the water channel can meet the requirement by arranging a plurality of the bottom surfaces of the water channel on the horizontal ground in a subsection mode, then the sections are connected one by one to form a corrugated water channel, and the flow direction of water in the water channel can be controlled by arranging the water supply port and the water discharge port of the system on the water channel. When the water channels are arranged on a slope, the slope can also be designed into similar corrugated water channels to adjust or strengthen the slope effect of the system.

In general, the bottom surface of the waterway, which is determined by fig. 12-a and fig. 13-a, 13-b, 13-c and 13-d, respectively, may be regarded as a trajectory in which the contour line of the bottom surface of the waterway, which is formed by the wheel band 122a and the non-wheel band 123a in the cross-sectional view of fig. 12-a, is continuously moved in a specific space. Accordingly, it is not difficult for those skilled in the art to include, but not limited to, the contour lines of the bottom surfaces of the water channels in the transverse cross-sectional views of fig. 12-a, 12-b, 12-c, 12-d and 12-e as the moving lines, and the trajectories of the continuous movement of these moving lines in a given condition and space are designed to be suitable for the bottom surfaces of the water channels of the present invention, which will not be described herein.

It should be understood that the motion trajectory may be given by the contour lines of the bottom surface of the channel in the transverse cross-sectional view of fig. 12-a as the motion lines, and may be designed for the bottom surface of the channel of the present invention including, but not limited to, the bottom surface of the channel determined by fig. 12-a and 13-a, the bottom surface of the channel determined by fig. 12-a and 13-b, the bottom surface of the channel determined by fig. 12-a and 13-c, and the bottom surface of the channel determined by fig. 12-a and 13-d.

In addition, the contour lines of the bottom surfaces of the channels in the longitudinal sectional views, including but not limited to FIGS. 13-a, 13-b, 13-c and 13-d, are motion lines, and the continuous motion trajectories of these motion lines in a given condition and space can be designed to be used for the bottom surfaces of the channels according to the present invention.

Generally, the flume floor is designed according to the designs including fig. 12-a, 12-b, 12-c, 12-d and 12-e, or fig. 13-a, 13-b, 13-c and 13-d, which have the same transverse cross-section or the same longitudinal cross-section, respectively. According to different requirements, the bottom surface in one water channel in the embodied water channel design can be designed to have various cross section patterns or longitudinal section patterns, so that the system is adaptive to the arranged environment, and the technical scheme is optimized.

Optionally, the bottom surface of the waterway may include one or more lateral grooves.

For example, regarding the contour line of the cross section of the bottom surface of the waterway shown in fig. 12-e as a moving line, a waterway bottom surface in which one or more transverse grooves are provided can be designed according to the trajectory of the moving line for straight continuous movement on a plane, and a transverse waterway bottom surface including grooves suitable for the present invention can be obtained. The top view of the bottom surface of the water channel is shown in fig. 14-a, and the cross-sectional view of the place where the lateral grooves are provided is shown in fig. 14-b.

The channel floor shown by fig. 14-a and 14-b includes channel band 122f, channel non-band 123f, channel non-band 124f, and transverse grooves 129. Wherein the water channel wheel track 122f includes grooves 127; the water channel non-wheel track belt 123f comprises a protrusion 125f, the protrusion 125f comprises a backflow groove 126, and the backflow groove 126 comprises a groove 127; water way non-tracking strip 124f includes protrusions 128, and protrusions 128 include grooves 127. The transversely disposed grooves 129 communicate with the grooves 127 disposed at the water channel non-tracking band 124f, the water channel non-tracking band 123f, and the water channel tracking band 122f, respectively. As the vehicle passes through the waterway, the water 121 therein is agitated and/or splashed, which water causes at least a portion of the vehicle, including the vehicle chassis, to be washed, and the water that falls back after washing at least partially enters the backwash tank 126 to flow in a direction opposite to the direction of travel of the vehicle. Since the return channel provided on the projection 125f is higher than the bottom surface of the water channel at the water channel wheel track 122f, the upstream fallen water can flow back into the water channel of the downstream wheel track via the return channel 126 and the transverse groove 129.

In particular, a filter body may be arranged at the backwash tank and/or the trough, and at least partial purification of the water channel may be achieved by means of the aforementioned flow characteristics of the backwash water in the water channel.

The transverse grooves in the bottom surface of the waterway shown in fig. 14-a and 14-b may be one or more, as desired. When the grooves are multiple, the grooves can be distributed on the bottom surface of the water channel uniformly or distributed non-uniformly. For example, when the backflow groove and/or the groove is provided with a filter body and emphasizes the water purification function of the water channel, the transverse groove can be, but is not limited to, a sparse upstream and a dense downstream distribution in the water channel. In general, the distance between the lateral grooves may be, but is not limited to, 1m to 50m.

In the solutions according to fig. 12-a, 12-b, 12-c, 12-d and 12-e, or fig. 14-a, 14-b, the width of the bottom surface of the waterway, including the waterway footprint strip and the waterway non-footprint strip, should match the width of the body of the motor vehicle and the functional requirements of the waterway. The water channel non-wheel-track belt comprises a water channel non-wheel-track belt in the middle (transverse) of the bottom surface of the water channel and water channel non-wheel-track belts on two sides of the bottom surface of the water channel. Generally, when the waterway is commonly used by hybrid vehicles and the waterway bottom does not include waterway non-wheel tracks on both sides, the width of the waterway bottom is sufficient for trucks and large cars (more than 30 passengers), for example, the width of the waterway bottom may be, but is not limited to, 2.6-3.8m, wherein the width of the non-wheel track in the middle portion of the waterway bottom may be, but is not limited to, 300-1500mm; when the bottom surface of the water channel comprises two side non-wheel-track belts (including or not including the backflow grooves and/or the grooves on the wheel-track belts), the width of the bottom surface of the water channel can be, but is not limited to, 2.6 meters to 3.8 meters, wherein the width of the non-wheel-track belt of the water channel at the middle part of the bottom surface of the water channel can be, but is not limited to, 300 mm to 1500mm, and the width of the non-wheel-track belt of the water channel at two sides can be, but is not limited to, 50 mm to 1000mm; when the water channel is limited to small motor vehicles including cars and the two sides of the bottom surface of the water channel do not include water channel non-wheel-track strips, the width of the bottom surface of the water channel can be, but is not limited to, 2 meters to 3 meters, wherein the width of the water channel non-wheel-track strips in the middle part of the bottom surface of the water channel can be, but is not limited to, 300 mm to 1000mm; when the water channel bottom surface comprises two side water channel non-wheel-track belts (with or without backflow grooves and/or grooves on the water channel wheel-track belts), the width of the water channel bottom surface can be, but is not limited to, 2 meters to 3.8 meters, wherein the width of the water channel non-wheel-track belt in the middle portion of the water channel bottom surface can be, but is not limited to, 300 mm to 1500mm, and the width of the two side water channel non-wheel-track belt can be, but is not limited to, 50 mm to 1000mm.

According to the invention, the water channel non-wheel track part forming the bottom surface of the water channel can be convex, concave or flat relative to the water channel wheel track part. Wherein, when the non-wheel track strip of the water channel in the middle (transverse) of the bottom surface of the water channel is a bulge, the height of the bulge is limited by the minimum ground clearance of the motor vehicle, and generally, the height of the bulge can be but is not limited to 10mm-200mm; when the water channel non-wheel-track belts on both sides of the bottom surface of the water channel are convex, the convex height is not limited to 10mm-200mm, and when the backflow grooves are formed on the water channel non-wheel-track belts on both sides, the convex height can be 10mm-200mm in general in consideration of the efficiency of the backflow grooves into which water stirred and/or splashed can enter.

When the water channel non-wheel-track belt is provided with the backflow groove, on the premise that water which can be stirred and/or splashed can enter the backflow groove, and at least part of the flowing direction of the water enters the direction opposite to the driving direction of the motor vehicle, the pattern, the structure and the arrangement mode of the backflow groove can be flexibly designed according to the condition of the water channel non-wheel-track belt. For example, one or more backflow grooves, such as 1 to 10 grooves, may be provided on the water channel non-track belt intermediate the two water channel track belts; one water channel non-wheel track belt is arranged or arranged on each side of the water channel bottom surface. The reflow groove can be, but is not limited to, V-shaped, U-shaped, W-shaped and the like.

Generally, the backflow groove should have a corresponding adaptability in structure, including but not limited to, when a filter body (such as a filter cloth) is disposed in the backflow groove, for example, the backflow groove should be structurally configured with a component for fixing and detaching the filter body, so as to facilitate the detachment and attachment; when the backflow groove is provided with grooves in the transverse and/or longitudinal direction, the combined structure of the backflow groove and the grooves can be, but is not limited to, a funnel shape as shown in fig. 12-d, and the groove bottom of the groove is usually lower than the water channel bottom surface where the water channel wheel track belt is located, and for example, but not limited to, 10-400mm lower than the water channel bottom surface where the water channel wheel track belt is located.
