Description

Technical Field

[0001] The invention relates to the technical field of car wash tanks, in particular to an energy-saving car wash tank. Background Art

[0002] In the process of urban modernization, there are more and more construction projects such as urban and suburban buildings, municipal facilities, highways, integrated pipeline corridors, and subways. Large and small engineering vehicles frequently enter and exit the site. The mud and dust carried by the wheels are then ground by subsequent vehicles, and the dust particles can be as fine as nanometers. The dust raised by the car's rolling will float in the city for a long time. Except for a small part that is absorbed by urban greening, the rest will float in the air for a long time, which brings great pressure to the construction of civilized cities. To solve the problem of dust pollution, the best solution is to control and reduce the source of dust generation - construction project dust control.

[0003] To control dust, in addition to turning on fog cannons, spraying, sprinkling water to reduce dust, and washing vehicles entering and leaving, the best way is to reduce the number of vehicles on the road, reduce driving speed, and reduce the mud and dust on the wheels and under the chassis of the vehicles. The usual practice is to build a simple through-type car wash trough + washing platform. Each vehicle passes through the car wash trough, and the dust attached to the vehicle is briefly soaked in the car wash trough and then washed in the car wash platform before leaving the site in a hurry. Due to space limitations, the length of the car wash trough is generally about 14m, and the deeper water area is usually 6-8m, which is only enough for the wheels to roll two or three times. The splashes brought by the vehicles entering the car wash trough are mild. After "stroking" the wheels and chassis, it is time to go to the washing platform for washing. The mud that has not been soaked is still relatively firmly attached. If there is not enough time to wash, the efficiency is often lower than expected. The better projects currently are automatic washing with personnel assistance for targeted washing. The mud splashing everywhere during the washing process will also cause air pollution in a small area. When there are many vehicles entering and leaving, the queued vehicles seriously affect the normal traffic needs of the project. These processes are more likely to become formalities. Vehicles that are not washed clean in time will enter the municipal roads with dust and soil, which will have a negative impact on civilized urban life. Although there will be three-level sedimentation tanks on site, not all mud will enter the sedimentation tanks. It is still necessary to seize the time to clean the mud deposited in the car wash trough and car wash platform when there are fewer vehicles to ensure that the water in the car wash trough is clean and avoid clogging of the car wash platform. Washing vehicles and cleaning mud during rush work consumes a lot of manpower to achieve the expected results.

[0004] Based on this, the present invention designs an energy-saving car washing tank to solve the above problems. Summary of the Invention

DETAILED DESCRIPTION

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0025] See also Figure 1-4The invention provides a technical solution: an energy-saving car wash tank, comprising an import platform 1, a car wash tank 2 and a car wash station 3, wherein the car wash tank 2 is located between the import platform 1 and the car wash station 3 and is connected to the import platform 1 and the car wash station 3 respectively through ramps;

[0026] The front-to-back slope of the ramp from the entrance platform 1 to the car wash trough 2 is 1:6, and the front-to-back slope of the ramp from the car wash platform 3 to the car wash trough 2 is 1:8. The left-right slope of the ramp is 5%, and the lower side is the drainage side. Two water chutes 10 are set at intervals on the front and back of the ramp between the car wash trough 2 and the car wash platform 3; a louver-type splash guardrail 13 is set on the top of the car wash platform 3;

[0027] The car wash tank 2 is provided with outwardly convex curved side walls 4 on the left and right sides. The bottom surface of the car wash platform 3 is built with a certain slope to drain water to the side of the car wash tank 2. A number of grooves 41 and blocks 42 of different sizes are provided on the curved side walls 4. The two side ends of the curved side walls 4 extend to the sides of the ramp to form the car wash tank retaining wall 14.

[0028] The bottom of the car washing tank 2 is provided with a plurality of bottom plate steps 21 and diverter sills 22 at intervals in the front and rear, and the diverter sills 22 are provided in the middle of the bottom plate steps 21;

[0029] A bottom plate block 5 is provided in the middle of the car washing tank 2. The bottom plate block 5 plays a role in reflecting water waves, returning water flow to wash the bottom of the car, and plays an energy dissipation role after the car passes, slowing down the flow rate and allowing the sediment to enter the sedimentation tank;

[0030] The side of the car wash tank 2 is connected to a three-stage sedimentation tank 6. The car wash tank 2 is provided with a drainage ditch 7, which can be used for water injection. When there is water in the surrounding area, the water can enter the car wash tank 2 through the drainage ditch to drain the surrounding ground water as soon as possible.

[0031] A limit retaining wall 8 is set on each side of the car wash tank 2, and the limit retaining wall 8 is connected to the slope of one side of the car wash station 3. The height of the limit retaining wall 8 is 200mm;

[0032] A sedimentation filter tank 9 is provided in the middle and side of the bottom surface of the car washing tank 2. The sedimentation filter tank 9 is provided with three filter screens from top to bottom: a steel water grate 91, a coarse mesh filter basket 92 and a fine mesh filter basket 93;

[0033] A side ditch 11 connected to the car wash tank 2 is provided on the drainage side of the ramp, and one end of the side ditch 11 is horizontally connected to a plurality of drainage ditches 12.

[0034] Specific working example:

[0035] The two side walls of the car wash trough 2 are changed into curved side walls 4, and the bottom surface of the car wash platform 3 is repaired to a certain slope to drain water to the side of the car wash trough 2 to form a side ditch 11. At the same time, a certain number of grooves 41 and blocks 42 of different sizes are provided on the curved side walls 4, and a certain number of bottom plate steps 21 and diverter ridges 22 are provided on the bottom plate of the car wash trough 2. The grooves 41 and blocks 42 on the curved side walls 4, the bottom plate steps 21 and diverter ridges 22 on the bottom plate of the car wash trough 2 work together to increase the water hammer effect;

[0036] Finally, when the vehicle enters the car wash tank 2, the non-uniform flow patterns such as gradual and sudden changes will impact the "groin" on the curved side wall 4, changing the water flow pattern and creating "dynamic water pressure, water hammer pressure, and wave pressure" to impact the vehicle body, tires and chassis, completing the wetting and washing of the vehicle. A louver-type splash guardrail 13 is set on the car wash platform 3, and the splashing mud and water generated during washing will be confined by the louver within the range of the car wash platform, achieving a more powerful mud and dust removal effect, reducing the washing pressure of the car wash platform, and saving water resources.

[0037] First, by changing the car wash tank 2 into an irregular cross-section, the two side walls of the car wash tank 2 at a deeper water level are changed into an outward arc shape, and the height of the side walls at a deeper water level is increased to achieve surface flow energy dissipation to avoid water splashing outward when vehicles pass through the car wash tank;

[0038] Secondly, a certain number of grooves 41 and blocks 42 of different sizes are provided along the front south direction on the curved side wall 4 of the car wash tank 2, so as to make full use of the reverse effect of the kinetic energy of the vehicle when entering the car wash tank 2 to generate non-uniform flow patterns such as gradual and sudden changes;

[0039] Then, in conjunction with the bottom plate steps 21 and diverter 22 provided on the bottom plate, the reverse principle of the water jump bottom energy dissipation and the combined effect of the diverter 22 increase the flow velocity and kinetic energy, thereby achieving the transition from slow flow to rapid flow, completing a complete set of actions of wetting and impact cleaning the vehicle body, tires, and bottom of the vehicle;

[0040] Finally, rinse clean with the help of car wash station 3 and leave the construction site.

[0041] In order to avoid the vehicle being deviated and scratched by the stress water flow when the vehicle is running too fast, a 200mm high limit wall 8 is set on each side of the car wash tank 2 to limit the vehicle wheel track, preventing the vehicle from deviating or even scratching the side wall due to the impact of the water flow. At the same time, it will also increase the water jumping effect and better wash the wheels and chassis.

[0042] Considering that the present invention has a strong flushing effect, a 60 cm deep sedimentation filter tank 9 is set on the bottom plate and side of the car wash tank, and three filter screens including a steel water grate 91, a coarse mesh filter basket 92 and a fine mesh filter basket 93 are respectively provided to preliminarily filter the mud and slag before discharging it into the tertiary sedimentation tank 6, so as to prevent the mud and slag from hitting the vehicle under the drive of "water hammer" and save construction water more effectively.

[0043] When there is no time to clean the bottom of the pool, the reinforced water grates 91 of the bottom sedimentation filter pool can be replaced with concrete covers to prevent the sedimentation slurry from "turning over" and polluting.

[0044] At the same time, two water chutes 10 are set on the exit ramp. When the vehicle passes the height difference, it will "jump off" to shake off some mud and water. The water chutes 10 are also provided with steel bar water grates 91.

[0045] The present invention only optimizes the original car wash tank, and will not cause a large increase in land resources and construction costs. By utilizing the kinetic energy of the vehicle body and the principle of hydraulic construction, it can achieve a better vehicle washing effect, reduce the hidden danger of vehicles carrying dust on the road, guard the last checkpoint for vehicles to leave the site, and better serve the civilized construction of the project. Therefore, the present invention is suitable for all projects that have car wash tanks to be built, especially projects in urban areas and nearby areas, and is also suitable for major car wash shops and entrances and exits of factories and companies.
