Description

Technical Field

[0001] This utility model relates to the field of construction vehicle washing technology, and in particular to a non-powered automatic spray vehicle washing device. Background Technology

[0002] The main function of a car wash pool is to clean vehicles when earthmoving vehicles enter and leave the site, reducing mud and water on the road. Currently, the most common car washing methods are manual car washing and car wash pool washing. However, manual wiping or manual water gun rinsing methods have disadvantages such as low efficiency, high water consumption, high labor costs, and poor cleaning effect.

[0003] Car washing in a car wash pool is the most common method, mainly including two types: flooded car wash pools and automatic car wash stations.

[0004] Flood-type car wash pools are mainly constructed of concrete or steel structures that collect water and store it. The wheels are repeatedly rolled in the water tank for simple rinsing, and additional water is needed to rinse the wheels and car body with a running water hose. Overall cleaning is inconvenient, time-consuming, labor-intensive, and does not achieve good cleaning results, while also wasting water resources.

[0005] Automatic car wash stations use multiple nozzles to wash vehicles, including the wheels, chassis, and body, achieving integrated and fully automated operation. This eliminates the need for dedicated personnel at construction site entrances and exits to create flowing water for car washing, thus avoiding significant waste of water and manpower. Automatic car wash stations are highly practical, enhancing washing effectiveness while significantly reducing washing time, improving the efficiency of earthmoving operations, and conserving water resources.

[0006] Automatic car wash stations achieve automatic car washing functions through intelligent control systems. Their application scenarios require municipal power and water supply. In some construction sites, there is often a lack of municipal water and electricity supply, which often limits their application. In addition, the process is relatively complex and requires frequent operation and maintenance.

[0007] Regarding the aforementioned technologies, the applicant believes that the following defects exist: flood-type car wash pools are simple in construction and have a wide range of applications, but their rinsing effect is poor and they waste water resources; automatic washing stations have a high degree of automation and a good rinsing effect, but their structure is complex and their operation and maintenance are troublesome. In addition, they require municipal water and electricity and cannot be used in some remote areas. Utility Model Content

[0037] The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0038] Specific embodiments of the non-powered automatic spray car wash device provided by this utility model:

[0039] Please see Figure 1-6 The non-powered automatic spray car wash device includes a car wash component 6, a mechanically driven water pump 2, a sedimentation tank 1, a transmission component 7, a water supply pipe 3, a drainage pipe 4, and a spray component 5.

[0040] The mechanically driven water pump 2 is a submersible centrifugal pump, including a pump shaft 201, a pump inlet 202, and a pump outlet pipe 203. The pump shaft 201 is connected to a belt drive mechanism 204. The mechanically driven water pump 2 is self-priming and can draw water. In some other embodiments, other types of water pumps can be used instead of centrifugal pumps.

[0041] The transmission assembly 7 includes a drive shaft 701. The mechanically driven water pump 2 is connected to the drive shaft 701 in the transmission assembly 7 via a belt drive mechanism 204. The belt drive mechanism 204 includes two pulleys and an annular belt. The belt connects the two pulleys to achieve linkage. The two pulleys are respectively connected to the drive shaft 701 and the water pump shaft 201. The outer diameter of the pulley connected to the drive shaft 701 is larger than the outer diameter of the pulley connected to the water pump shaft 201. Therefore, the belt drive mechanism 204 makes the output speed of the transmission assembly 7 lower than the input speed of the mechanically driven water pump 2. The rotation of the drive shaft 701, through the belt drive mechanism 204, can drive the water pump shaft 201 and the impeller of the mechanically driven water pump 2 to rotate and perform work.

[0042] Mechanically driven water pump 2 is installed in the upper part of sedimentation tank 1, and the water outlet pipe 203 of mechanically driven water pump 2 is connected to water supply pipe 3. Mechanically driven water pump 2 delivers water to car wash assembly 6 and spray assembly 5 on the upper side through water supply pipe 3. Spray assembly 5 cleans the vehicle body and tires by spraying water, and the vehicle is thoroughly cleaned to ensure that the vehicle does not carry mud on the road.

[0043] The car wash assembly 6 includes a car wash pool 605, a sedimentation tank 1 located on one side of the car wash pool 605, and spray assembly 5 installed inside and on both sides of the upper side of the car wash pool 605. A drain pipe 4 connects the bottom of the car wash pool 605 and the sedimentation tank 1. After washing the car, the water flows into the bottom of the car wash pool 605 and then enters the sedimentation tank 1 through the drain pipe 4, where mud and water are separated. The recycled water is then used for further cleaning.

[0044] The sedimentation tank 1 adopts a three-compartment structure, with two partition walls 104 dividing it into three sections: the first section, the second section, and the third section. The silt-laden water from washing cars enters the sedimentation tank 1 and then sequentially flows into the third section, the second section, and finally the first section. Overflow holes 105 are located at the top of the partition walls 104, allowing the silt to settle at the bottom of the sections, while clean water flows through the overflow holes 105. The silt from the washing process primarily settles in the third and second sections. A mechanically driven water pump 2 is located above the first section to ensure its normal operation and the quality of the washing water.

[0045] Each tank in sedimentation tank 1 has a V-shaped gravity sludge discharge hopper 101 at its bottom for accumulating and discharging sludge. A sludge discharge pipe 102 is installed at the bottom of the gravity sludge discharge hopper 101. The sludge discharge pipe 102 includes several branch pipes and a main pipe. The branch pipes pass through sedimentation tank 1 and correspond to the bottom of the gravity sludge discharge hopper 101 in each tank. The outer end of the branch pipe is connected to the main pipe, and a sludge discharge valve 103 is installed on the main pipe. Sludge is discharged by gravity, and the sludge discharge valve 103 is opened by the upstream water head pressure. In addition to normal sludge discharge, the sludge discharge valve 103 also controls the water level in sedimentation tank 1. In some embodiments, the same sludge discharge structure as sedimentation tank 1 can also be provided under the car wash pool 605.

[0046] In this embodiment, each sedimentation tank 1 is equipped with two gravity sludge discharge hoppers 101 at its bottom and six branch pipes. In some embodiments, the inner diameter of the branch pipes in the second tank is larger than that in the first tank, and the inner diameter of the branch pipes in the third tank is larger than that in the second tank.

[0047] The car wash assembly 6 includes a car wash pool 605, a steel grating beam 601, a steel panel 602, and a pipe support 603. The steel panel 602 at the inlet and outlet of the car wash assembly 6 has a 2% slope towards the inside of the car wash pool 605 to collect washing water and reduce mud and water on the road. Two steel panels 602 are provided, located on the outer sides of both ends of the car wash pool 605. The end of the steel panel 602 furthest from the car wash pool 605 is higher than the end closest to the car wash pool 605, with the height difference between the two ends being 2% of the length between the two ends. The upper side of the steel panel 602 is provided with anti-slip textures or anti-slip protrusions to ensure smooth passage for vehicles.

[0048] The main component of the car wash assembly 6, the steel grating beam 601, is set on the upper side of the car wash pool 605 and covers the pool opening of the car wash pool 605. The steel grating beam 601 has a mesh structure, which facilitates the bottom spray device to clean the bottom of the vehicle, saves materials and facilitates drainage. At the same time, it allows vehicles to enter and exit by passing over the upper side of the car wash pool 605.

[0049] The transmission assembly 7 is installed inside the car wash pool 605, partially passing through the steel grating beam 601. This allows the car tires to contact the transmission assembly 7. Pipe supports 603 are installed on the upper sides of both edges of the car wash pool 605, supporting the spray assembly 5.

[0050] The spray assembly 5 includes a water distribution pipe 501, the inlet of which is connected to the water supply pipe 3. Part of the water distribution pipe 501 is installed at the bottom of the car wash basin 605, and another part is installed on a pipe support 603. A plurality of spray heads 502 are installed along the water distribution pipe 501, including a plurality of vertical spray heads 502 and a plurality of horizontal spray heads 502. The spray heads 502 spray water onto the car from the underside and sides to wash away mud and sand from the outer sides of the car's chassis and tires. In some embodiments, some spray heads 502 spray water vertically onto the car, while others spray water at an angle, which can wash the tire ring sides and the uneven surfaces of the chassis.

[0051] The transmission assembly 7 includes a transmission shaft 701, a transmission belt 702, a rotating shaft 703, and belt rollers 704. The transmission belt 702 has a ring structure and two belts are arranged laterally. The upper part of the transmission belt 702 passes through the steel grating beam 601. The transmission belt 702 adopts a mesh chain structure or a rubber track structure. A surrounding steel plate 604 is provided between the transmission belt 702 and the steel grating beam 601, or on the upper side of the steel grating beam 601 around the transmission belt 702. The surrounding steel plate 604 surrounds the transmission belt 702 with gaps, and the upper side of the surrounding steel plate 604 has anti-slip textures or anti-slip protrusions.

[0052] Two parallel rollers 704 are rotatably mounted inside the car wash pool 605. The rollers 704 support both ends of the transmission belt 702, allowing the transmission belt 702 to rotate. Each roller 704 supports the same end of two transmission belts 702. In some embodiments, an anti-slip structure is provided between the rollers 704 and the transmission belt 702 to prevent slippage. In other embodiments, annular chains are provided on both sides of the transmission belt 702, and matching sprockets are provided on the rollers 704. A connecting rod is connected between the chains on both sides, and the connecting rod passes through the transmission belt 702. The drive shaft 701 is a shaft that passes through one end of the roller 704 of the transmission belt 702. The drive shaft 701 is rotatable and extends into the sedimentation tank 1, driving the mechanical transmission water pump 2 through the belt drive mechanism 204.

[0053] Several rotating shafts 703 are provided and rotatably installed in the car wash pool 605. The rotating shafts 703 are located on the lower side of the upper part of the transmission belt 702, supporting the transmission belt 702 and the car, improving the support strength, and contacting the transmission belt 702, rotating with the rotation of the transmission belt 702.

[0054] The drive belt 702 maintains stable movement through its own rigidity and the support of the rotating shaft 703 and the rollers 704. After the vehicle enters the upper side of the drive assembly 7, the drive belt 702 is generally linearly curved, with higher ends and a lower middle. The surrounding steel plate 604 and the steel grating beam 601 are also curved, with higher ends and a lower middle, and are adapted to and smoothly correspond to the drive belt 702. The drive belt 702 is driven to rotate by the friction of the wheels and gravity. The rotation of the wheels causes the drive belt 702 to rotate in the opposite direction, and the vehicle continues to move at a certain speed for a period of time until it is clean. After the vehicle is cleaned, the vehicle speed is increased and the driving direction is changed, and the vehicle drives out of the drive assembly 7 and onto the steel panel 602 of the car wash assembly 6, and finally drives out. In some embodiments, several strip-shaped protrusions or stripes are provided along the outer side of the drive belt 702 to increase the friction between it and the car tires.

[0055] The sidewall of the car wash pool 605 is provided with bearings and sealing structures to support the drive shaft 701. The drive shaft 701 is arranged along its entire length, connecting the double-sided drive components 7 and the mechanical drive water pump 2. In some embodiments, the drive shaft 701 and the mechanical drive water pump 2 can be directly connected via a coupling or via a belt drive mechanism 204, depending on the usage and maintenance conditions of the mechanical drive water pump 2. The drive shaft 701 drives the impeller of the mechanical drive water pump 2 to rotate, and through continuous motion, the mechanical drive water pump 2 fills with water and stably supplies water to the spray assembly 5 to complete the cleaning. The pressure and flow rate of the spray assembly 5 can be adjusted according to the actual situation by adjusting the vehicle speed. Through mechanical transmission, the vehicle washing is completed fully automatically. In this embodiment, the belt drive mechanism 204 makes the input speed of the mechanical drive water pump 2 greater than the speed of the drive shaft 701. In some embodiments, an accelerator is added between the drive shaft 701 and the mechanical drive water pump 2 to give the mechanical drive water pump 2 a higher input speed.

[0056] The car enters the car wash device and continues to drive at a certain speed. During the driving process, the transmission belt 702 of the transmission component 7 driven by the car tires rotates, and the car does not leave the washing area. The mechanical transmission water pump 2 is driven by the transmission shaft 701 and then the car is washed by the spray component 5. After being cleaned, the car leaves the device by changing its speed or direction.

[0057] During the cleaning process, as the driver lightly presses the accelerator, the tires begin to rotate, which in turn drives the transmission assembly 7 to rotate rapidly. The transmission belt 702 drives the transmission shaft 701, which connects to the water pump shaft 201. The water pump impeller rotates and delivers water to the spray assembly 5. This tire-driven method efficiently converts the power of the dump truck into the power required by the cleaning device. The power comes from the earthmoving vehicle, which drives the transmission assembly 7 to ultimately drive the mechanically driven water pump 2 for washing, without requiring additional power.

[0058] The car wash pool 605 is equipped with steel panels 602 at both its inlet and outlet, with the inlet and outlet sloping towards the area of ​​the car wash pool 605. A steel grating beam 601 is arranged on the upper side of the car wash pool 605. The arrangement of the grating and the inlet and outlet facilitates cleaning and water recycling. In some embodiments, water-blocking strips are provided on the upper sides of both edges of the steel panel 602 to facilitate water flow into the car wash pool 605 and prevent water overflow.

[0059] The spray assembly 5 is equipped with multiple high-pressure water nozzles 502, which can spray high-pressure water jets onto the dump truck from different angles and heights. For areas of the dump truck such as the body, chassis, and tires where large amounts of construction waste easily accumulate, the spray nozzles 502 provide powerful, continuous water spray from multiple angles. The water used for the spray washing system is fully recycled, requiring only a small amount of replenishment to maintain water balance. The water is stored in the sedimentation tank 1, and the mechanically driven water pump 2 delivers water to the spray system at the bottom and sides of the washing pool 605. Wastewater from vehicle washing flows quickly into the sedimentation tank 1 through the pre-installed drainage troughs and pipes 4 at the bottom of the washing area.

[0060] In some embodiments, a filter screen is installed inside the overflow hole 105. In the sedimentation tank 1, the wastewater first undergoes preliminary sedimentation in the third tank, where larger particles of slag and other impurities settle to the bottom. Subsequently, the water flows through the second tank and the filter screen to further remove fine particles and impurities, and finally flows into the first tank of the sedimentation tank 1, where it is pumped again by the mechanically driven water pump 2 for cleaning operations, forming an efficient closed loop for water resource recycling.

[0061] The sedimentation tank 1 uses gravity sludge discharge. The sludge settles to the bottom and is collected by a V-shaped gravity sludge discharge hopper 101. Then, it is discharged to the relevant area through the sludge discharge pipe 102. The sludge discharge is completed by the water pressure at the top.

[0062] This device was tested and applied to the flood drainage and waterlogging renovation project of Hutanggou Canal in Yudu Street, Xinyi City. The project covers a long area with many sites and a large amount of earthwork. It is used at the construction site of earthwork in rivers and lakes. It automatically washes vehicles without power, does not require municipal power supply, and the water source can be obtained from nearby rivers and lakes, ensuring that mud and water do not go on the road. There is no need to wash the road frequently or maintain the car wash equipment. The device is economical and environmentally friendly.

[0063] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still make modifications to the technical solutions described in the foregoing embodiments without creative effort, or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
