Description

Technical Field

[0001] This utility model relates to the field of car wash equipment technology, and in particular to a combination car wash equipment for construction sites. Background Technology

[0002] Currently, construction sites mostly use three-stage car wash machines that combine flooding, rinsing, and draining. These machines are highly integrated, from washing tires to rinsing vehicles, and then manually replenishing the water and allowing it to drain back. In theory, this ensures that the roads are free of mud and that no mud or water spills.

[0003] However, in reality, many key and detailed issues arise that affect its efficiency and increase the difficulty of maintenance and repair, as follows:

[0004] (1) The washing of mud inside the tires is not considered: Traditional construction site car wash machines only consider the washing of the outside of the machine body and do not consider the washing of mud inside the tires. It is difficult to manually wash them. Although they seem to be washed clean, mud that is hard to find will still be thrown out after the vehicle leaves the site, causing road pollution. In addition, manually washing the inside of the wheels often requires bending over, and frequent operation can easily cause occupational diseases that damage the back muscles.

[0005] (2) Mud easily accumulates in the foundation trench and under the steel grate in the drainage area of ​​the washing machine, and it is very inconvenient to clean, resulting in a waste of manpower and affecting the efficiency of soil washing, which in turn causes mechanical idleness.

[0006] The drainage area cannot be cleaned mechanically and can only be cleaned manually, which is very troublesome.

[0007] Washing area: It is difficult to clean manually and must be cleaned little by little. When soil is frequently excavated, it needs to be cleaned at least once every 3 days.

[0008] (3) Although the car wash system is equipped with a three-stage sedimentation tank, the temporary three-stage sedimentation tank is not effective in filtering debris and cleaning sludge. Setting up a formal sludge treatment equipment is too expensive and not suitable for small temporary facilities. In addition, the cost of vacuum trucks is high. If the three-stage sedimentation tank is not cleaned in time, the following problems will occur during construction:

[0009] Damaged strips of dustproof netting, geotextile, etc., enter the tertiary sedimentation tank, causing equipment blockage. The actual sludge filtration effect of the tertiary sedimentation tank is poor. When a lot of soil is discharged, it is difficult to clean, resulting in idle machinery. Or, if cleaning is not timely, water pump blockage occurs, leading to equipment failure.

[0010] Sedimentation tank cleaning: Manual cleaning often takes 2-3 days, severely impacting construction progress. Mechanical cleaning takes 1 day, but it easily damages the brick walls of the sedimentation tank, requiring the pump to be lifted. Vacuum truck cleaning is also expensive, costing approximately 10,000 yuan per cleaning, and requires cleaning every 3 days when soil removal is frequent.

[0011] (4) When washing manually, mud and water splash out. Vehicles need to drive in and out of the flood pool repeatedly, causing mud and water to accumulate around the vehicle, making it difficult to wash the vehicle clean and increasing the possibility of mud on the road.

[0012] (5) The gaps between vehicle tires, the guide rail grooves of the earthwork cover shed, and the grooves of other vehicles are difficult points for washing mud. It is difficult to manually replenish the mud, which seriously affects the efficiency of car washing. Even if a washing device is added, the vehicle cannot be thoroughly cleaned.

[0013] Chinese patent CN104999999A discloses a vehicle washing device for construction sites, including a vehicle driving steel plate and a steel structure base. The vehicle driving steel plate is set on the steel structure base, and there are two vehicle driving steel plates. The two vehicle driving steel plates are welded together to form a washing trough for vehicles to pass through. The vehicle driving steel plate is a flat steel plate with a groove. The steel structure base is equipped with a spray pipe, and the spray pipe is equipped with a nozzle. The nozzle is directly opposite the groove. Inner high-pressure nozzles are respectively provided on both sides of the drainage ditch, and outer high-pressure nozzles are provided on the guardrail for the outer side of the slag truck wheels. The inner and outer high-pressure nozzles are connected to external tap water through a water pump. The wheels and their inner and outer sides are automatically cleaned to prevent mud from the construction site from scattering on the road.

[0014] Although the car wash equipment can clean both the inner and outer sides of the wheels, it does not specifically clean the car body, which will still have varying degrees of mud on it. Furthermore, since the wash is done in only one washing tank, it can easily create blind spots and cannot thoroughly clean the car body and tires at the same time.

[0015] In addition, the wastewater from this car wash equipment is prone to splashing out and there is no wastewater collection device. On the one hand, it is difficult to ensure the cleanliness of the rinsing water, and on the other hand, it expands the area where mud and water are scattered, increasing the difficulty and workload for workers to clean.

[0016] In addition, the car wash equipment involves a large workload and is difficult to clean silt. Summary of the Invention

[0017] To address the aforementioned problems, this utility model aims to provide a construction site vehicle washing combination device that can reduce mud and water overflow and eliminate blind spots in the washing process, thereby improving washing efficiency and washing effect.

[0018] The main idea of ​​the technical solution adopted by this utility model is as follows: setting up intercepting ditches and sedimentation tanks to facilitate the collection of sewage and prevent sewage from spreading everywhere; setting up a first nozzle and a second nozzle in the flooded area to wash both the vehicle body and the inside of the tires, preventing the existence of washing dead corners; setting up a semi-circular drainage channel to facilitate the cleaning of mud and water; setting up a first screen, a sedimentation tank, and a second screen to filter mud, sand, and fiber waste on the one hand, and reduce the difficulty and frequency of cleaning the sedimentation tank on the other hand, thus saving costs.

[0019] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0020] A construction site car washing assembly includes a flooded area, a car washing area, and a draining area arranged sequentially from left to right along the same axis; the flooded area includes a flood pool; the car washing area includes a car washing platform, and second baffles are connected to the front and rear sides of the car washing platform.

[0022] The flood pool is provided with a first baffle and a flushing component on the front and rear sides respectively. The flushing component includes several water supply vertical pipes arranged from left to right along the first baffle, and each water supply vertical pipe is connected to at least two first nozzles.

[0023] Both the first baffle and the second baffle are used to block water.

[0024] Furthermore, through the above technical solution, the first nozzles connected to two adjacent water supply risers are distributed at different heights.

[0025] Furthermore, the above technical solution further includes: the car wash platform is connected to several drainage channels arranged parallel to each other in the front-to-back direction; at least two parallel water supply horizontal pipes are connected above the drainage channels; the water supply horizontal pipes are arranged along the direction of vehicle travel and are located in the middle of the car wash platform; and a second nozzle is connected to the side of the water supply horizontal pipe facing the second baffle.

[0026] Furthermore, through the above technical solution, the second nozzle is oriented diagonally upwards away from the horizontal water supply pipe.

[0027] Furthermore, through the above technical solution, the drainage channel is semi-circular with the curved part located at the bottom.

[0028] Furthermore, the intercepting ditch and the sedimentation tank are connected in sequence by a first partition net, a sludge bucket, and a second partition net.

[0029] Furthermore, the bottom of the flood pool is provided with several raised strips, which are used to slow down bumpy vehicles.

[0030] Furthermore, the bottom of the flood pool is provided with several semi-circular blocks with raised bottom surfaces, which are used to slow down bumpy vehicles.

[0031] The beneficial effects of this utility model are as follows: Compared with the prior art, the improvement of this utility model lies in that...

[0032] ① By setting up intercepting ditches around the perimeter of the flooded area, car wash area and draining area, it is possible to reduce mud and water overflow, maintain the cleanliness of the roads around the car wash facilities, reduce the difficulty of road cleaning, and prevent vehicles from running over mud and water and causing secondary pollution.

[0033] ② By setting up a first spray nozzle at a staggered height through the water supply vertical pipe and a second spray nozzle set diagonally above the water supply horizontal pipe, it is possible to wash both the vehicle body and the inside of the tires, eliminating blind spots in the washing process, accurately cleaning areas prone to mud accumulation, and improving washing efficiency.

[0035] ④ By setting up a first partition net, a sludge bucket, and a second partition net between the intercepting ditch and the sedimentation tank, garbage can be blocked, making it convenient for personnel to clean up in a timely manner, increasing the continuity of car wash machine use, reducing the cleaning frequency and difficulty of the sedimentation tank, and saving costs.

[0036] ⑤ A deceleration and bump-reducing component is installed in the flood pool to increase vehicle vibration, which helps to remove mud from the tires and increases car washing efficiency.

[0037] In summary, this utility model, through the vehicle's bumpy ride in the flooded area and the washing of the vehicle body by the first spray nozzles at varying heights, followed by the washing of the inner tires in the car wash area, and finally the draining area, greatly improves the washing efficiency and effect of the entire washing process. Furthermore, it significantly reduces the number of times mud is brought onto the road due to inadequate washing, greatly reducing the frequency of routine maintenance and sludge removal from the sedimentation tank, thus saving costs.

[0043] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0044] The inventors discovered that construction site car wash equipment suffers from several technical problems, including blind spots, easy splashing of wastewater, and significant workload and difficulty in cleaning sludge. This increases labor costs and incurs high sludge removal fees, severely impacting car wash efficiency.

[0045] Based on the above findings, this application proposes a combined vehicle washing device for construction sites. The structural design of intercepting ditches along the outer perimeter of the flooded area, washing area, and draining area can prevent sewage from spreading everywhere. The flooded area is equipped with a first nozzle and a second nozzle, which can wash both the vehicle body and the inside of the tires, preventing any blind spots in the washing process. The first screen, sedimentation tank, and second screen can filter mud, sand, and fibrous waste, greatly reducing the frequency of daily maintenance and sedimentation tank cleaning, thus saving costs. The device also improves washing efficiency and washing effect.

[0046] Example 1

[0047] Referring to Figures 1-4, this application discloses a construction site car washing combination device, including a flooding area 1, a car washing area 2 and a draining area 3 arranged sequentially from left to right along the same axis;

[0048] A water interception ditch 4 is provided around the perimeter of the flooded area 1, the car wash area 2 and the drain area 3. The water interception ditch 4 is connected to a sedimentation tank 5. The water interception ditch 4 can prevent mud and water from overflowing, making site cleaning difficult, and causing secondary pollution of the road surface due to vehicles driving over mud and water.

[0049] Sedimentation tank 5 has a depth of 2000mm and performs 3-stage filtration. After the bottom and inner wall of sedimentation tank 5 are plastered, a 3mm thick SBS waterproof membrane layer is applied. After the waterproof membrane is applied, a 120mm protective wall is built.

[0050] Leave a 500mm high and 200mm wide overflow outlet at a position 300mm from the top of the two middle partitions to the longitudinal walls on both sides. The sedimentation tank 5 should be no more than 3m away from the car wash pool, and the surrounding pool top should be hardened for water drainage and aesthetic purposes. The pool top should be at least 200mm higher than the surrounding ground and covered with a hard cover.

[0051] The flooded area 1 includes a flood pool. First baffles 1-2 and flushing components are respectively installed on the front and rear sides of the flood pool. The flushing components include several water supply risers 1-3 arranged from left to right along the first baffles 1-2. Each water supply riser 1-3 is connected to at least two first nozzles 1-4. The first nozzles 1-4 connected to adjacent water supply risers 1-3 are staggered in height to eliminate blind spots in flushing. The first nozzles 1-4 are common nozzles of existing technology, which will not be described in detail here.

[0052] The flood pool has no roof. The first baffle 1-2 is 2600mm high. Because the flood pool has a slope, the surface should be roughened to prevent vehicles from slipping later.

[0053] Nine water supply risers 1-3 are installed on each side of the flood pool, with the first riser starting at 3400mm and spaced 1000mm apart. The highest point of each water supply riser 1-3 (the first nozzle 1-4) varies from 2200 to 1800mm. The height of the first nozzle 1-4 starts at 400 to 600mm from the top of the embankment, with each subsequent nozzle spaced 500mm apart, and the highest point spaced 500 to 600mm apart, totaling four nozzles 1-4. This allows for precise cleaning of areas prone to soil accumulation in vehicle ruts, significantly enhancing the washing effect.

[0054] The flooded pool has net dimensions of 15000*4000 mm. Its main function is to soften and wash large pieces of mud off vehicle wheels, facilitating subsequent washing. The lowest point of the flooded pool is 550 mm deep, and the curb height is 200 mm.

[0055] [Car wash area 2 includes a car wash platform and a car wash shed 2-6. Second baffles 2-2 are connected to the front and rear sides of the car wash platform. The front and rear sides of the car wash shed 2-6 are flush with the second baffles 2-2. The top of the car wash shed 2-6 is directly above the car wash platform. The car wash platform is connected to several drainage channels arranged parallel to each other in the front-rear direction. At least two parallel horizontal water supply pipes are connected above the drainage channels. The horizontal water supply pipes are arranged along the direction of vehicle travel and are located in the middle of the car wash platform. A second nozzle is connected to the side of the horizontal water supply pipe facing the second baffle 2-2. The second nozzle faces diagonally upwards away from the horizontal water supply pipe. The second nozzle uses a common nozzle from existing technology, which will not be described in detail here.]

[0056] Car wash machine canopy 2-6 has dimensions of 4000mm wide, 6000mm long, and 5000mm high. The car wash machine protective canopy is installed on the foundation.

[0057] The water supply horizontal pipe uses DN80SC pipe. When the second nozzle needs to be adjusted in direction, a universal joint is added at the connection between the second nozzle and the water supply horizontal pipe to adapt to the washing of different vehicles.

[0058] When a vehicle passes by, the second nozzle automatically starts to wash the inside of the wheels. The angle of the second nozzle can be adjusted according to the type of vehicle, so that the inside of the wheels can be washed without manual washing, thus improving washing efficiency and reducing the risk of occupational diseases.

[0059] After the vehicle passes by, the inside of the wheels can be washed clean, eliminating the need for manual washing of the inside of the wheels at the front, thus speeding up the washing process and accelerating the overall vehicle washing speed.

[0060] Both the first baffle 1-2 and the second baffle 2-2 are used to block water and prevent spilled water from flowing outside the car wash area.

[0061] Drainage area 3 has a net plan dimension of 12000*4500 and is pre-embedded with 10# channel steel at 500mm intervals. Its main function is to collect the dripping water from the vehicle body after washing and to collect sewage during manual washing.

[0062] Traditional car wash machines use welded steel pipes for their water inlet pipes. Vibrations from moving vehicles can easily cause these welds to detach, leading to leaks, water pressure loss, insufficient washing pressure, and reduced washing effectiveness, resulting in more frequent maintenance. In contrast, the washing machine features a flexible connection between the equipment and the water supply pipe, enhancing vibration resistance, preventing pipe damage from vehicle traffic, and reducing maintenance frequency.

[0063] Example 2

[0064] The structure of this embodiment is the same as that of the construction site car wash combination device in Embodiment 1. The only difference is that the drainage trough is semi-circular and the curved part is located at the bottom. This facilitates the cleaning of mud and water under the car wash machine, and the mud and water basically flow away, reducing the phenomenon of mud and sand accumulating and settling in the original concrete ditch.

[0065] Example 3

[0066] Please refer to Figures 1 and 3. The structure of this embodiment is the same as that of the construction site car washing combination device in Embodiments 1 and 2. The only difference is that the intercepting ditch 4 and the sedimentation tank 5 are connected in sequence by a first partition net 6, a sludge bucket 7 and a second partition net 8.

[0067] A first wire mesh screen 6 is installed at the point where the intercepting ditch 4 leads to the sedimentation tank 5 to intercept larger clumps of mud and fibrous waste. Two more dense wire mesh screens 8 are added in the intercepting direction to slow down the water flow. A sedimentation tank 7 is installed in front of the dense mesh screen. The sedimentation tank 7 has dimensions of 300*500*800 mm and is made of welded steel bars, reinforced with wire mesh, and sealed with geotextile. When lifted, some of the water inside can be filtered out. By filtering and reducing the water flow rate during the process, the amount of mud and sand filtered can be greatly reduced, thus significantly reducing the number of times the sedimentation tank 5 needs to be cleaned.

[0068] The sedimentation tank 7 can be lifted for cleaning at any time, and can be lifted manually. It has 3 spare tanks and can be cleaned every half hour. The cleaning difficulty and frequency of the sedimentation tank 5 are reduced by at least 50%. This reduces cleaning costs and improves the continuity of the car wash machine's use.

[0069] Example 4

[0070] The structure of this embodiment is the same as that of the construction site car washing combination device in Embodiments 1, 2 and 3. The only difference is that the bottom of the flood pool is provided with several deceleration and bumping components.

[0071] The deceleration and bump-reducing components can be made of steel strips or semi-circular concrete blocks with round dots, which can increase the bumpiness of the vehicle in the flooded pool and promote the shedding of mud and sand from the tires.

[0072] The specific usage process of this utility model is as follows: Connect the power supply to ensure that the car wash machine can operate normally.

[0073] In the first stage of washing, the dump trucks pass through the flooded area 1 at low speed. The trucks can go back and forth through the flooded area 1 three times, staying for 25 seconds. After passing through the flooded pool, large pieces of mud on the truck are softened and washed away. On the other hand, the mud and water on the tires are washed off by passing through the deceleration and bumping components strip belts or semi-circular blocks. The truck body is then washed by the first nozzles 1-4, which precisely clean the grooves of the truck where soil is easy to accumulate, greatly increasing the washing effect.

[0074] The second stage of washing involves vehicles passing through the initial rinsing area 1 and then entering the car wash area 2. Vehicles pass through slowly, pausing for 12 seconds. During this time, the car wash machine rinses the vehicle, while a second nozzle washes the inside of the tires, avoiding blind spots and improving washing efficiency. The second nozzle can be adjusted in direction as needed to suit different vehicles.

[0075] The third stage of water draining: After the vehicle has been washed in the first two stages, it enters the draining zone 3 to collect the water dripping from the vehicle body after washing.

[0076] The water from the flooded area 1, car wash area 2, and draining area 3 is discharged into the intercepting ditch 4, then through the first screen 6, sedimentation tank 7, and second screen 8 to the sedimentation tank 5, where it is reused after three stages of sedimentation.

[0077] The segmented water spray control can balance cleaning efficiency and energy saving requirements, making it suitable for frequent use scenarios on construction sites. It also reduces the frequency of maintenance and the difficulty of mud removal, shortens the time for manual supplementary rinsing by 1.5 times, improves rinsing efficiency, reduces vehicle congestion, and improves construction efficiency.

[0078] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
