Description

Technical Field

[0001] The present invention relates to the technical field of construction vehicle washing, and particularly relates to a non-powered automatic spraying vehicle washing device. Background Art

[0002] The main function of the vehicle washing pool is to wash the vehicles when the earth-rock vehicles enter and leave the site, reducing the muddy water on the road. Currently, the most common vehicle washing methods are manual vehicle washing and vehicle washing in the washing pool. However, the methods of manual scrubbing or manually holding a water gun for flushing have the disadvantages of low efficiency, large water consumption, high labor cost, and poor washing effect.

[0003] Washing the vehicle in the washing pool is the most commonly used method, mainly including two methods: the overflow type washing tank and the automatic washing platform.

[0004] The overflow type vehicle washing pool is used to clean the dirt. Its main structure is a concrete or steel structure water collecting tank, which stores clean water. The vehicle is simply washed by repeatedly rolling the wheels in the water tank, and a supplementary flowing water pipe is needed to flush the wheels and the vehicle body. The overall cleaning is inconvenient, time-consuming and laborious, and cannot achieve a good cleaning effect, and also wastes water resources.

[0005] The automatic washing platform flushes the vehicle through multiple groups of nozzles, including the wheels, chassis and vehicle body, realizing integration and full automation. There is no need to set up special personnel at the construction site entrance and exit to create the conditions for washing the vehicle with flowing clean water using tools such as water guns, avoiding serious waste of water resources and human resources. The automatic washing platform has high practicability. While enhancing the washing effect, it also greatly shortens the vehicle washing time, improves the work efficiency of earthwork transportation, and saves water resources.

[0006] The automatic washing platform realizes the automatic vehicle washing function through an intelligent control system. Its application scenarios require municipal power supply and water supply.

Detailed Embodiment

[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings. The drawings are simplified schematic diagrams, only illustrating the basic structure of the present invention in a schematic manner, so they only show the components related to the present invention.

[0028] Specific embodiments of the power-free automatic spraying car washing device provided by the present invention: Please refer to Figures 1-6 , a power-free automatic spraying car washing device, including a car washing component 6, a mechanical transmission water pump 2, a sedimentation tank 1, a transmission component 7, and a water supply pipe 3, a drainage pipe 4, and a spraying component 5.

[0029] The mechanical transmission water pump 2 is a submersible centrifugal pump, including a water pump shaft 201, a water pump inlet 202, and a water pump outlet pipe 203. The water pump shaft 201 is connected to a belt transmission mechanism 204. The mechanical transmission water pump 2 self-priming and absorbing water. In some other embodiments, other types of water pumps can be used to replace the centrifugal pump.

[0030] The transmission component 7 includes a transmission shaft 701. The mechanical transmission water pump 2 is connected to the transmission shaft 701 in the transmission component 7 through the belt transmission mechanism 204. The belt transmission mechanism 204 includes two belt pulleys and an annular belt. The belt connects the two belt pulleys to achieve linkage. The two belt pulleys are respectively connected to the transmission shaft 701 and the water pump shaft 201. The outer diameter of the belt pulley connected to the transmission shaft 701 is larger than the outer diameter of the belt pulley connected to the water pump shaft 201. Furthermore, the belt transmission mechanism 204 makes the output speed of the transmission component 7 lower than the input speed of the mechanical transmission water pump 2. The rotation of the transmission shaft 701 can drive the water pump shaft 201 and the impeller of the mechanical transmission water pump 2 to rotate and do work through the belt transmission mechanism 204.

[0031] The mechanical transmission water pump 2 is installed in the upper part of the sedimentation tank 1. The water pump outlet pipe 203 of the mechanical transmission water pump 2 is connected to the water supply pipe 3. The mechanical transmission water pump 2 transports water to the car washing component 6 and the spraying component 5 on the upper side through the water supply pipe 3. After the spraying component 5 sprays water flow to clean the body and tires of the passing vehicle, the vehicle is thoroughly cleaned to ensure that the vehicle does not carry mud on the road.

[0032] The car washing component 6 includes a car washing pool 605. The sedimentation tank 1 is located on one side of the car washing pool 605. The spraying component 5 is installed inside and on both upper sides of the car washing pool 605. A drainage pipe 4 is connected between the bottom of the car washing pool 605 and the sedimentation tank 1. After the water after car washing flows into the bottom of the car washing pool 605, it enters the sedimentation tank 1 through the drainage pipe 4 and completes sediment-water separation in the sedimentation tank 1, and its circulating water continues to be used for washing.

[0033] The sedimentation tank 1 adopts a three - compartment structure. There are two partition walls 104 inside the sedimentation tank 1, which divide the sedimentation tank 1 into three tank bodies, namely the first tank body, the second tank body, and the third tank body. The sediment - laden water after washing the car enters the sedimentation tank 1 and then successively enters the third tank body, the second tank body, and the first tank body step by step. There are overflow holes 105 provided at the upper part of the partition walls 104. The sediment falls and settles at the bottom of the tank body, and the clear water passes through the overflow holes 105. The sediment after washing mainly settles in the third tank body and the second tank body. The mechanical - drive water pump 2 is arranged at the upper part of the first tank body to ensure the normal operation of the mechanical - drive water pump 2 and the quality of the washing water.

[0034] At the bottom of each tank body of the sedimentation tank 1, there are V - shaped gravity sludge hoppers 101 for accumulating and discharging sediment. A sludge discharge pipe 102 is arranged at the bottom of the gravity sludge hopper 101. The sludge discharge pipe 102 includes several branch pipes and a main pipe. The branch pipes pass through the sedimentation tank 1 and correspond to the bottoms of the gravity sludge hoppers 101 of each tank body of the sedimentation tank 1. The outer ends of the branch pipes are connected to the main pipe, and a sludge discharge valve 103 is installed on the main pipe. The sludge discharge utilizes gravity. The sludge discharge valve 103 is opened by the water - head pressure of the upstream water level for sludge discharge. Besides normal sludge discharge, the sludge discharge valve 103 also has the function of controlling the water level of the sedimentation tank 1. In some embodiments, a sludge discharge structure the same as that of the sedimentation tank 1 can also be arranged on the lower side of the car - washing pool 605.

[0035] In this embodiment, two gravity sludge hoppers 101 are arranged at the bottom of each tank body of the sedimentation tank 1, and the number of branch pipes is six. In some embodiments, the inner diameter of the branch pipes in the second tank body is larger than that in the first tank body, and the inner diameter of the branch pipes in the third tank body is larger than that in the second tank body.

[0036] The car - washing assembly 6 includes a car - washing pool 605, a steel grid beam 601, a steel panel 602, and a pipe support 603. The steel panel 602 at the inlet and outlet of the car - washing assembly 6 is set with a 2% slope towards the inside of the car - washing pool 605 to collect the washing water and reduce the muddy water on the road. Two steel panels 602 are provided, respectively located on the outer sides of both ends of the car - washing pool 605. The end of the steel panel 602 far from the car - washing pool 605 is higher than the end close to the car - washing pool 605, and the height difference between the two ends is 2% of the length between the two ends. Anti - slip patterns or anti - slip protrusions are provided on the upper side of the steel panel 602 to ensure the smooth passage of the car.

[0037] The main component of the car - washing assembly 6, the steel grid beam 601, is arranged on the upper side of the car - washing pool 605 to cover the pool opening of the car - washing pool 605. The steel grid beam 601 is a grid - like structure, which is convenient for the bottom spraying device to wash the bottom of the vehicle, saves materials and is conducive to drainage. At the same time, it allows the vehicle to enter and exit through the upper side of the car - washing pool 605.

[0038] The transmission assembly 7 is installed in the car wash pool 605 and partially passes through the steel grid beam 601, enabling the car tires to come into contact with the transmission assembly 7. The pipe support 603 is installed on the upper sides of the two side edges of the car wash pool 605 to support the spraying assembly 5.

[0039] The spraying assembly 5 includes a water distribution pipe 501. The water inlet end of the water distribution pipe 501 is connected to the water supply pipe 3. Part of the water distribution pipe 501 is installed at the bottom inside the car wash pool 605, and part of the water distribution pipe 501 is installed on the pipe support 603. A number of spray heads 502 are installed along the water distribution pipe 501, including a number of vertical spray heads 502 and a number of horizontal spray heads 502. The spray heads 502 spray water on the car from the lower side and both sides of the car to wash the sediment on the outer sides of the car chassis tires. In some embodiments, some of the spray heads 502 spray water vertically on the car, and some of the spray heads 502 spray water obliquely on the car, which can wash the side of the tire ring and the concave and convex surfaces of the chassis.

[0040] The transmission assembly 7 includes a transmission shaft 701, a transmission belt 702, a rotating shaft 703 and a belt roller 704. The transmission belt 702 is of an annular structure and two are arranged horizontally. The upper part of the transmission belt 702 passes through the steel grid beam 601. The transmission belt 702 adopts a mesh chain structure or a rubber track structure. A surrounding steel plate 604 is arranged between the periphery of the transmission belt 702 and the steel grid beam 601 or on the upper side of the steel grid beam 601 on the periphery of the transmission belt 702. The surrounding steel plate 604 surrounds the transmission belt 702 with a gap, and the upper side of the surrounding steel plate 604 has anti-slip lines or anti-slip protrusions.

[0041] Two parallel belt rollers 704 are rotatably installed in the car wash pool 605. The belt rollers 704 support both ends of the transmission belt 702, enabling the transmission belt 702 to rotate. Each belt roller 704 supports the same end of the two transmission belts 702. In some embodiments, an anti-slip structure is arranged between the belt roller 704 and the transmission belt 702 to prevent slipping. In some other embodiments, annular chains are arranged on both sides of the transmission belt 702, sprockets matching therewith are arranged on the belt rollers 704, a connecting rod is connected between the two side chains, and the connecting rod passes through the transmission belt 702. The transmission shaft 701 is a shaft fixedly passing through one end belt roller 704 of the transmission belt 702. The transmission shaft 701 is rotatable and extends into the sedimentation tank 1 to drive the mechanical transmission water pump 2 to operate through the belt transmission mechanism 204.

[0042] A number of rotating shafts 703 are arranged and rotatably installed in the car wash pool 605. The rotating shafts 703 are located below the upper part of the transmission belt 702, support the transmission belt 702 and the car, improve the support strength, and are in contact with the transmission belt 702 and rotate with the rotation of the transmission belt 702.

[0043] The drive belt 702 maintains normal and stable movement through its own stiffness and the support of the rotating shaft 703 and the belt rollers 704. After the vehicle enters the upper side of the transmission assembly 7, the overall linear shape of the drive belt 702 is an arc with higher front ends and lower middle part. Both the surrounding steel plate 604 and the steel grid beam 601 are arcs with higher ends and lower middle part, which are adapted to and smoothly correspond to the drive belt 702. The frictional force and gravity of the wheels on the drive belt 702 drive the drive belt 702 to rotate. The rotation of the wheels makes the drive belt 702 rotate in the reverse direction and keeps the vehicle moving at a certain speed for a period of time until the vehicle is washed clean. Then, after increasing the vehicle speed and changing the driving direction, the vehicle drives out onto the steel panel 602 of the car wash assembly 6 and finally drives out. In some embodiments, a number of strip protrusions or strip patterns are provided on the outer side of the drive belt 702 to increase the frictional force with the automobile tires.

[0044] Bearings and sealing structures for supporting the transmission shaft 701 are provided on the side wall of the car wash tank 605. The transmission shaft 701 is arranged throughout the length and connects the bilateral transmission assemblies 7 and the mechanical transmission water pump 2. In some embodiments, the transmission shaft 701 and the mechanical transmission water pump 2 can be directly connected through a coupling or can be connected through a belt drive mechanism 204, which can be determined according to the use and maintenance conditions of the mechanical transmission water pump 2. The transmission shaft 701 drives the impeller of the mechanical transmission water pump 2 to rotate. Through continuous movement, the mechanical transmission water pump 2 is filled with water and stably supplies water to the spraying assembly 5 to complete the cleaning. And the pressure and flow rate of the spraying assembly 5 can be adjusted by adjusting the vehicle speed according to the actual situation. Through mechanical transmission, the vehicle washing is completed automatically. In this embodiment, the belt drive mechanism 204 makes the input speed of the mechanical transmission water pump 2 higher than the speed of the transmission shaft 701. In some embodiments, an accelerator is added between the transmission shaft 701 and the mechanical transmission water pump 2 to make the mechanical transmission water pump 2 have a higher input speed.

[0045] When the car drives into the car wash device, it continues to drive at a certain speed. During the driving process, the drive belt 702 of the transmission assembly 7 driven by the car tires rotates while the car does not drive out of the washing area. After the transmission shaft 701 drives the mechanical transmission water pump 2 to operate, the car is washed by the spraying assembly 5. After being washed clean, the car drives out of the device by changing the speed or direction.

[0046] During the cleaning process, as the driver gently steps on the accelerator, the tires start to rotate, which in turn drives the transmission assembly 7 to operate quickly. The drive belt 702 drives the connection between the transmission shaft 701 and the pump shaft 201 of the water pump. Through the rotation of the water pump impeller, water is transported to the spraying assembly 5. In the way driven by the tires, the power of the muck truck is efficiently converted into the power required by the cleaning device. The power comes from the earthwork transportation vehicle. Through the vehicle driving the transmission assembly 7, finally the mechanical transmission water pump 2 is driven to carry out the cleaning without additional power supply.

[0047] Steel panels 602 are provided at both the inlet and outlet of the car wash pool 605. The inlet and outlet parts slope towards the area of the car wash pool 605. A steel grid beam 601 is arranged on the upper side of the car wash pool 605. The arrangement of the grid and the inlet and outlet is conducive to cleaning and recycling water. In some embodiments, water retaining strips are provided on the upper sides of both edges of the steel panel 602, which is conducive to the water flowing into the car wash pool 605 and preventing water from overflowing.

[0048] The spray assembly 5 is equipped with multiple high-pressure spray nozzles 502, which can spray high-pressure water flows onto the muck truck from different angles and heights. For the parts of the muck truck body, chassis, tires, etc. where a large amount of muck is easily accumulated, the spray nozzles 502 spray powerful water continuously from multiple angles. The water used for spray car washing adopts full-circulation water use. Only a small amount of water replenishment is required to ensure water volume balance. The water flow is stored in the sedimentation tank 1. The mechanical transmission water pump 2 conveys water to the spray systems at the bottom and sides of the car wash pool 605. The sewage after vehicle washing quickly flows into the sedimentation tank 1 through the drain grooves and drain pipes 4 preset at the bottom of the cleaning area.

[0049] In some embodiments, a filter screen is provided in the overflow hole 105. In the sedimentation tank 1, the sewage first undergoes preliminary sedimentation in the third tank body, and impurities such as larger particles of muck precipitate to the bottom of the third tank body. Subsequently, the water flow passes through the second tank body and is filtered by the filter screen to further remove fine particles and impurities, and finally flows into the first tank body of the sedimentation tank 1 for the mechanical transmission water pump 2 to extract again for cleaning operations, forming an efficient closed-loop of water resource recycling.

[0050] The sludge discharge of the sedimentation tank 1 adopts gravity sludge discharge. The sediment is collected in the V-shaped gravity sludge hopper 101 set at the bottom, and then discharged to the relevant area through the sludge discharge pipe 102. The sludge at the bottom is discharged completely by the water head pressure at the top.

[0051] This device is applied to the flood control and drainage renovation project of Hutang Ditch in Yudu Street, Xinyi urban area. The project has a long front line, many points and a wide area, and a large amount of earthwork. It is used at the construction site of earthwork in rivers and lakes. It can wash vehicles without power and automation, without municipal power supply. The water source can be obtained from the nearby rivers and lakes, ensuring that the muddy water does not get on the road, and there is no need to often wash the road and maintain the car washing device. The device is economical and environmentally friendly.

[0052] Finally, it should be noted that the above-mentioned are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still make modifications to the technical solutions recorded in the foregoing embodiments without creative labor, or perform equivalent replacements for some of the technical features.
