Description

Technical Field

[0001] This application relates to the technical field of car wash pools, and in particular to a car wash pool for construction sites. Background Art

[0002] Currently, at civil engineering construction sites, the tires and chassis of vehicles are easily covered with mud and sand after entering, and it is necessary to clean the tires and chassis of the vehicles subsequently to prevent the mud and sand impurities adhered to the vehicle bottom from polluting the municipal roads.

[0003] When usually cleaning the incoming and outgoing vehicles, construction workers hold high-pressure water pipes to wash them. This cleaning method has low efficiency, so some car wash pools for cleaning vehicles have emerged. A grid-shaped installation frame is usually arranged above the car wash pool. A cavity for water supply to flow is arranged inside the installation frame, and a plurality of nozzles are arranged on the top of the installation frame. After the vehicle enters the car wash pool, the nozzles spray water upward to wash the wheels and chassis. However, the cleaning effect of this cleaning method is limited, and the cleaning effect on the wheels needs to be further improved. Summary of the Utility Model

[0004] In order to enhance the cleaning effect on the wheels, this application provides a car wash pool for construction sites.

[0005] The car wash pool for construction sites provided by this application adopts the following technical solutions:

[0006] A car wash pool for construction sites includes a cleaning pool, a spraying mechanism, and a cleaning mechanism. The spraying mechanism is arranged in the cleaning pool and is used for spraying the passing vehicles. Four groups of cleaning mechanisms are arranged, and the four groups of cleaning mechanisms are symmetrically arranged on both sides in the width direction of the cleaning pool. The cleaning mechanism includes a first rotary power member, a turntable, and bristles. The first rotary power member is fixedly arranged on one side of the cleaning pool, the turntable is coaxially and fixedly connected to the output end of the first rotary power member, and the bristles are fixedly arranged on the turntable and can abut against the wheels.

[0007] By adopting the above technical solutions, during the working process, the spraying mechanism can spray the vehicle. At the same time, the first rotary power member drives the turntable to rotate, and the bristles on the turntable can clean the wheels, thereby enhancing the cleaning effect on the wheels and also helping to improve the cleaning efficiency.

[0008] Optionally, adjustment mechanisms are provided on both sides of the cleaning tank. Each adjustment mechanism corresponds to two cleaning mechanisms on one side of the cleaning tank. The adjustment mechanism includes a mounting plate, mounting blocks, and an adjustment assembly. The mounting plate is arranged along the length direction of the cleaning tank. There are two mounting blocks, which are slidably arranged on the mounting plate along the length direction of the mounting plate. Each first rotary power member is fixedly connected to the corresponding mounting block. The adjustment assembly is arranged on the mounting plate and is used to drive the two mounting blocks to slide in opposite directions so as to adjust the distance between the two mounting blocks.

[0009] By adopting the above technical solution, the adjustment assembly can adjust the distance between the two mounting blocks, thereby adjusting the distance between the two turntables. When the distance between the front and rear wheels of the vehicle is different, it can be adjusted as needed, thus improving the adaptability of the device.

[0010] Optionally, the adjustment assembly includes a second rotary power member and a double-headed screw. The second rotary power member is fixedly connected to the mounting plate. The rotation axis of the output end of the second rotary power member is parallel to the length direction of the mounting plate. The double-headed screw is coaxially fixedly connected to the output end of the second rotary power member. The thread directions at both ends of the double-headed screw are opposite. One end of the double-headed screw is threadedly connected to one of the mounting blocks, and the other end of the double-headed screw is threadedly connected to the other mounting block.

[0011] By adopting the above technical solution, after the second rotary power member is started, it can drive the double-headed screw to rotate, causing the two mounting blocks to slide in opposite directions, thereby adjusting the distance between the two mounting blocks and completing the adjustment of the distance between the turntables. The structure is simple, stable and reliable.

[0012] Optionally, support rods are fixedly arranged on the periphery of the cleaning tank. The mounting plate is slidably arranged on the support rods along the width direction of the cleaning tank. A power telescopic member is arranged on the support rods, and the movable end of the power telescopic member is fixedly connected to the mounting plate.

[0013] By adopting the above technical solution, the power telescopic member can drive the mounting plate to slide. Therefore, before the vehicle enters the cleaning tank, the distance between the bristles on the two turntables is greater than the width of the vehicle. After the vehicle drives into the cleaning tank, the power telescopic member then drives the two turntables to approach each other, so that the bristles on the turntables are in contact with the wheels, and then the mud on the wheels is rotated and wiped off. Therefore, the setting of the turntables and bristles is not likely to impede the driving of the vehicle.

[0014] Optionally, the spraying mechanism includes a mounting frame, a first spray head, and a pump body. The mounting frame is arranged inside the cleaning tank. A cavity for water to flow is formed inside the mounting frame. The first spray head is fixedly connected to the top wall of the mounting frame and is communicated with the cavity inside the mounting frame. The water inlet end of the pump body is communicated with the water source, and the water outlet end of the pump body is communicated with the cavity inside the mounting frame.

[0015] By adopting the above technical solution, after the pump body is started, water can be sent into the installation frame, and then the water in the installation frame is sprayed upward through the first nozzle, so as to clean the chassis and wheels of the vehicle.

[0016] Optionally, it further includes a circulation mechanism arranged on one side of the cleaning pool. The circulation mechanism includes support columns and sedimentation tanks. The support columns are fixedly connected to the bottom wall of the cleaning pool. There are multiple support columns arranged at intervals, and a water guide groove is formed between adjacent two support columns. The sedimentation tank is arranged on one side of the cleaning pool. There are multiple sedimentation tanks arranged in sequence, and adjacent two sedimentation tanks are communicated with each other. The water guide groove is communicated with one end of the sedimentation tank, and the pump body is communicated with the other end of the sedimentation tank.

[0017] By adopting the above technical solution, after the water sprayed washes the vehicle, the water mixed with sediment can fall into the water guide groove, and then flow into the sedimentation tank at the starting end along the water guide groove. Since there are multiple sedimentation tanks, the dirty water after cleaning can be sedimented multiple times to separate impurities such as sediment in the dirty water, and then the filtered and separated water is pumped back into the pump body for recycling, which can improve the utilization rate of water resources and reduce waste.

[0018] Optionally, a filter screen is arranged at the part where adjacent two sedimentation tanks are communicated.

[0019] By adopting the above technical solution, solid particles in the water can be filtered, so as to enhance the treatment effect on sewage.

[0020] Optionally, the bottom of the water guide groove is arranged to incline downward from the end far away from the sedimentation tank to the end close to the sedimentation tank.

[0021] By adopting the above technical solution, it is convenient for the water in the water guide groove to flow into the sedimentation tank quickly, and the accumulation of sewage at the bottom of the water guide groove can be avoided.

[0022] Optionally, side plates are arranged on both sides in the width direction of the cleaning pool, and second nozzles are fixedly connected to the sides of the two side plates close to each other.

[0023] By adopting the above technical solution, the second nozzles on the side plates can spray the side walls of the wheels, so as to increase the spraying range and help to enhance the cleaning effect.

[0024] Optionally, slopes are arranged at both ends in the length direction of the cleaning pool, and the sides of the two slopes close to each other incline towards the bottom of the cleaning pool.

[0025] By adopting the above technical solution, the water in the cleaning pool can be prevented from overflowing outward through both ends of the cleaning pool.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. When the vehicle is being washed, on the one hand, the spray mechanism can spray the chassis and wheels of the vehicle, and on the other hand, the rotating turntable and brush bristles can rotate and wipe the sediment on the outer side of the wheels, thus helping to enhance the cleaning effect of the wheels and improve the cleaning efficiency.

[0028] 2. The distance between the two turntables can be adjusted adaptively according to the distance between the wheels, so the device can be adapted to different vehicle models or different wheels on the same vehicle body, and the adaptability of the device is stronger.

There are three sedimentation tanks 52, and they are arranged at intervals along the length direction of the cleaning tank 1. Connection ports 521 are arranged on the side walls of the three sedimentation tanks 52 close to the top. The connection ports 521 on adjacent two sedimentation tanks 52 are connected to each other through pipelines, so that the three sedimentation tanks 52 are communicated with each other. The bottom of the connection groove 12 is communicated with the starting sedimentation tank 52, so that the sewage in the connection groove 12 can enter the sedimentation tank 52 for treatment. After three times of sedimentation treatment, impurities such as sediment in the sewage are separated, and the separated water can be recycled, thereby improving the utilization rate of water resources. Further, a filter screen 522 is fixedly connected at the connection port 521 on the side wall of the sedimentation tank 52, so that the impurities in the sewage can be further filtered, thereby enhancing the treatment effect on the sewage.

[0037] Refer to Figure 1 and Figure 3, a spraying mechanism 2 is provided at the top of the cleaning tank 1. The spraying mechanism 2 includes a mounting frame 21, a first spray head 22, and a pump body 23. The mounting frame 21 is arranged on the top surface of the support column 51, and the bottom wall of the mounting frame 21 is in contact with the top wall of the support column 51.

Therefore, after the pump body 23 is started, the first spray head 22 can spray water upward, so as to spray and clean the vehicle parked on the top surface of the mounting frame 21. The water after cleaning will be mixed with impurities such as sediment on the wheels and fall into the water guide groove 11, and then flow into the sedimentation tank 52 through the water guide groove 11 and the connecting groove 12 in sequence. After sedimentation and filtration treatment, it is pumped into by the pump body 23 again, so as to be recycled.

[0038] Cleaning mechanisms 3 are also provided at the edges of the cleaning tank 1, and there are four groups of cleaning mechanisms 3; two groups of cleaning mechanisms 3 are provided on each side in the width direction of the cleaning tank 1, and the two groups of cleaning mechanisms 3 are arranged at intervals.

The turntable 32 is a disc, and the turntable 32 is coaxially and fixedly connected to the end of the output shaft of the first rotary power member 31. The brush hairs 33 are fixedly connected to the side of the turntable 32 away from the first rotary power member 31. Therefore, after the first rotary power member 31 is started, it can drive the turntable 32 to rotate, the turntable 32 drives the brush hairs 33 to rotate, and the ends of the brush hairs 33 are in contact with one side of the wheel. Therefore, the rotating brush hairs 33 can brush off impurities such as sediment adhering to the wheel, so as to further clean the wheel.

[0039] Adjusting mechanisms 4 are provided on both sides in the width direction of the cleaning tank 1. Each adjusting mechanism 4 corresponds to two cleaning mechanisms 3 on the same side and is used to adjust the distance between the two cleaning mechanisms 3. The adjusting mechanism 4 includes a mounting plate 41, a mounting block 42, and an adjusting assembly 43. The mounting plate 41 is provided on one side of the cleaning tank 1. The length direction of the mounting plate 41 is parallel to the length direction of the cleaning tank 1, and the plate surface of the mounting plate 41 is horizontal. Two mounting blocks 42 are provided and arranged at intervals. The mounting blocks 42 are slidably arranged on the top surface of the mounting plate 41 along the length direction of the mounting plate 41. The two mounting blocks 42 respectively correspond to two first rotating power members 31. Each first rotating power member 31 is fixedly connected to the top surface of the corresponding mounting block 42 by bolts.

[0040] The adjusting assembly 43 includes a second rotating power member 431 and a double-headed screw 432. The second rotating power member 431 is a motor.

The two mounting blocks 42 are respectively threadedly connected to both ends of the double-headed screw 432. Therefore, under the restriction of the mounting plate 41 on the mounting blocks 42, after the second rotating power member 431 is started, the two mounting blocks 42 can slide in opposite directions, thereby adjusting the distance between the two mounting blocks 42 to adapt to different wheel distances.

[0041] Further, vertical support rods 6 are fixedly connected to the edge of the cleaning tank 1. There are four support rods 6 and they are respectively located at the four corners of the cleaning tank 1.

Therefore, the power telescopic member 7 can drive the mounting plate 41 to slide along the width direction of the cleaning tank 1, so that the turntables 32 on both sides move towards the side close to or away from each other.

[0042] In addition, side plates 8 are fixedly connected to both sides in the width direction of the cleaning tank 1, and the side plates 8 are arranged vertically; a cavity is provided inside the side plates 8, and second spray nozzles 81 are fixedly connected to one side of both side plates 8 close to each other. The water outlet ends of the second spray nozzles 81 are arranged horizontally, and the water outlet ends of the second spray nozzles 81 on both side plates 8 face the side close to each other; the second spray nozzles 81 communicate with the cavity inside the side plates 8, and the cavity inside the side plates 8 also communicates with the water outlet end of the pump body 23. Therefore, after the pump body 23 is started, the wheels can be sprayed through the second spray nozzles 81, thereby enhancing the cleaning effect on the wheels.

[0043] The implementation principle of a car wash tank for a construction site in an embodiment of the present application is as follows: In the initial state, the distance between the ends of the bristles 33 on the two turntables 32 is greater than the width of the vehicle; the vehicle is driven into the cleaning tank 1 and parked on the top surface of the mounting frame 21; then the pump body 23 is started, the first spray nozzles 22 located at the bottom of the vehicle spray upward, and the second spray nozzles 81 located on both sides of the vehicle spray horizontally to clean the chassis and wheels of the vehicle. Then the movable end of the power telescopic member 7 extends, causing the mounting plate 41 to slide toward the side close to the vehicle body and making the bristles 33 abut against the side surface of the wheel; then under the action of the first rotary power member 31, the turntable 32 rotates, and the turntable 32 drives the bristles 33 to rotate, thereby brushing off the sediment adhered to the wheels and further cleaning the wheels. After the cleaning is completed, the power telescopic member 7 makes the mounting plate 41 move away from the vehicle body again, then the first rotary power member 31 stops working, and then the vehicle can be driven out of the cleaning tank 1.

[0044] The sewage during the spraying process falls into the water guide groove 11, then flows into the connection groove 12 along the water guide groove 11, then flows into the sedimentation tank 52 at the starting end, and then passes through the sedimentation and filtration treatment of each level of sedimentation tank 52 in sequence to purify the sewage. The purified water is then pumped into the pump body 23 for recycling, reducing waste.

[0045] The above are the optional embodiments of the present application, and the protection scope of the present application is not limited accordingly.
