Description

Technical Field

[0001] The invention relates to the technical field of road surface drainage, cooling and maintenance, and in particular to an integrated device for road surface drainage, cooling and maintenance. Background Art

[0002] With the acceleration of urbanization and the continuous growth of traffic volume, the road environment faces severe challenges, especially in the rainy and hot seasons. Road waterlogging, water damage and high temperature damage have become important factors affecting the service life of roads and driving safety. Asphalt pavement, as a common road paving material, shows obvious fragility in the face of these environmental pressures. Under the influence of long-term vehicle loads and environmental factors, asphalt pavement is prone to pits, looseness, cracks and other diseases. These diseases not only shorten the service life of the road, but also increase maintenance costs and pose a threat to driving safety.

[0003] The water damage problem of asphalt pavement is mainly manifested in the water damage of asphalt caused by water accumulation on the road, which reduces the strength of the pavement and accelerates the aging process of asphalt. In addition, under high temperature conditions, asphalt pavement will absorb a lot of heat, causing the temperature of the pavement to rise, further accelerating the oxidation and aging process of asphalt, significantly reducing the performance of the asphalt pavement, increasing maintenance costs, and causing damage to vehicle tires, affecting driving safety. Existing methods or equipment can often only solve a single problem, such as drainage, cooling or maintenance, and lack comprehensive solutions. These devices usually have a low degree of automation, rely on manual operation, are inefficient, and may have an impact on the environment.

[0004] With the introduction of the sponge city concept, the design concept of urban pavement has shifted to emphasize the absorption, storage and utilization of rainwater to achieve water recycling and ecological balance. However, existing technologies often fail to fully realize this concept, especially in terms of recycling of road surface water and energy conservation and emission reduction.

[0005] The present invention aims to solve the above problems and provide a comprehensive road surface treatment device that integrates the functions of waterlogging removal, cooling and maintenance. The device can quickly remove road surface water and reduce asphalt water damage; automatically adjust the road surface temperature to reduce high temperature damage; intelligently maintain the road surface and extend the service life of the road. By recycling road surface water for cooling and maintenance, the device not only saves water resources, but also achieves energy conservation and emission reduction, which is in line with the concept of sponge city and sustainable development.

[0040] Example 1

[0041] Reference Figure 1-2, which is the first embodiment of the present invention, provides an integrated device for road surface waterlogging removal, cooling and maintenance, which includes:

[0042] The delivery system 1 includes a suction nozzle 11, a water delivery pipeline 12, a two-way booster 13, and a water spray tank 14;

[0043] The water storage system 2 includes a water storage device 21, a partition plate 22, a movable gate 23, a curing material feeding port 24, a stirring paddle 25, a water injection port 26, and a drainage port 27;

[0044] The sensor control system 3 includes a signal processing center 31, a temperature-water level sensor 32, a water quality monitoring sensor 33, a display screen 34, and a water level sensor 35;

[0045] The filtration system 4 includes a centrifugal filter 41 , a movable valve 42 , a solid impurity conveyor belt 43 , a solid impurity storage device 44 , a water treatment filter element 45 , and a filtration circulation device 46 .

[0046] In this embodiment, in the conveying system 1, the suction nozzle 11 is installed on the hardened road surface, and the remaining components are installed below the hardened road surface. The other components of the water storage system 2, the sensor control system 3 and the purification system except the temperature-water level sensor 32 are buried below the ground.

[0047] Specifically, the suction nozzle 11 in the conveying system 1 is installed in the center of each lane and is flush with the hardened road surface. At the same time, the distance between two adjacent suction nozzles 11 on the same lane is consistent with the lane width. A two-way booster 13 is installed below the suction nozzle 11 and is threadedly connected to the water pipe 12. A two-way booster 13 is also installed at the connection between the conveying system 1 and the water storage system 2. The two sides of the two-way booster 13 are respectively connected to the water pipe 12 and the water storage device 21, and the bottom is connected to the water spray tank 14.

[0048] Furthermore, the side of the water storage device 21 in the water storage system 2 is connected to the two-way booster 13 and the water spray tank 14 in the conveying system 1, and the inside of the water storage device 21 is provided with a partition plate 22 which divides it into an upper and lower part, and the center of the partition plate 22 is provided with a movable gate 23 which controls the connection or separation of the upper and lower parts of the water storage device 21, and the side of the water storage device 21 is provided with a curing material feeding port 24, and stirring paddles 25 at the top and bottom of the lower half of the water storage device 21, and the side wall of the water storage device 21 is provided with a water quality monitoring sensor 33 and a water level sensor 35, and the top and side are provided with a water inlet 26 and a drain outlet 27 respectively.

[0049] Furthermore, the temperature-water level sensor 32 in the sensor control system 3 is installed at the lane line on the hardened road surface and is flush with the road surface. The water quality monitoring sensor 33 and the water level sensor 35 are installed on the side wall of the water storage device 21. The signal processing center 31 is connected to the suction nozzle 11, the two-way booster 13, the movable gate 23, the curing material feeding port 24, the stirring paddle 25, the water injection port 26, the drain port 27, the temperature-water level sensor 32, the water quality monitoring sensor 33, the display screen 34, the water level sensor 35, the centrifugal filter 41, the movable valve 42, the solid impurity conveyor belt 43, and the filtration circulation device 44 through a signal transmission line, and the display screen 34 is installed above the signal processing center 31.

[0050] Furthermore, the centrifugal filter 41 in the filtration system 4 is installed in the water pipe 12 and is connected to the water suction channel M of the suction nozzle 11, the solid impurity conveyor belt 43 is installed below the water pipe 12, and a movable valve 42 is installed in the connecting pipe between the water pipe 12 and the solid impurity conveyor belt 43. The end of the solid impurity conveyor belt 43 is connected to the solid impurity storage device 44, and the solid impurity storage device 44 is installed below the water storage device 21. The water treatment filter element 45 is installed above the partition plate 22. At the same time, the water treatment filter element 45 can move up and down together with the partition plate 22 according to the drainage requirements, and the two ends of the filtration circulation device are respectively connected to the upper and lower parts of the water storage device.

[0051] When in use, the road surface drainage function is realized: when water accumulates on the road surface, the water absorption channel M of the suction nozzle 11 is quickly opened, and the movable cover plate 112 is tilted downward under the action of water pressure and the two-way booster 13 to quickly absorb the water accumulated on the road surface. The accumulated water first passes through the coarse-mesh filter 111 to remove large-particle impurities, and then enters the centrifugal filter 41 to further filter out impurities with smaller particle sizes. The filtered water is transported to the water storage device 5 through the water pipeline 2. In this process, the temperature-water level sensor 11 of the sensor control system monitors the water accumulation on the road surface and transmits the data to the signal processing center 10, which controls the working status of the suction nozzle 11 and the two-way booster 13 to achieve the best drainage effect.

[0052] Furthermore, the road surface cooling function is realized: in a high temperature environment, the temperature-water level sensor 32 detects that the road surface temperature is too high, and the signal processing center 31 starts the cooling program according to the sensor data. The two-way supercharger 13 and the water spray tank 14 work together to transport the water in the water storage device 21 to the suction nozzle 11 through the water spray tank 14 and the water delivery pipeline 12, and the water is evenly sprayed onto the road surface through the spray channel N of the suction nozzle 11 to achieve a cooling effect. At the same time, the display screen 34 displays the road surface temperature and system operation status in real time for the operator to monitor.

[0053] Furthermore, the road maintenance function is realized: before road maintenance, the water quality in the water storage device 21 is monitored by the water quality monitoring sensor 33, and after ensuring that the water quality meets the requirements of the maintenance material ratio, the road maintenance material is added to the water storage device 21 through the maintenance material feeding port 24. The stirring paddle 25 is started under the control of the signal processing center 31 to fully mix the maintenance material with water. The mixed maintenance material is transported to the suction nozzle 11 through the water spray tank 14 and the water delivery pipeline 12, and the maintenance material is evenly sprayed onto the road surface through the spray channel M of the suction nozzle 11 to achieve road maintenance.

[0054] It should be noted that when the road surface is seriously flooded and the device needs to quickly drain the road surface water, the water treatment filter element 45 moves upward together with the partition plate 22 below it, reducing the volume of the water storage device 21, so that the accumulated water is not stored in the water storage device 21 but directly discharged into the municipal pipeline through the drain port 27; when the drainage is completed or the road surface water is not serious, the water treatment filter element 45 and the partition plate 22 below it move downward together again, increasing the volume of the water storage device 21, so that the accumulated water is stored in the water storage device 21, so that the accumulated water can be recycled, and sprayed with water for cooling after treatment or mixed with maintenance materials for road maintenance. In addition, the water storage device 21 has a water injection port 26 and a drain port 27 connected to the municipal pipeline, and is equipped with a water level sensor 35 to automatically control the water level in the water storage device 21, that is, when the road surface water volume is large, the drain port 27 is opened to quickly drain the road surface water, and when the road surface temperature is too high and there is no water in the water storage device 21, the water injection port 26 connected to the municipal water is opened to spray water for cooling.

[0055] Furthermore, the water treatment filter cartridge 45 has multiple functions, including the removal of suspended solids, algae removal, pH adjustment, removal of heavy metals and organic compounds, etc., to treat the water quality when spraying water for cooling or mixing with road maintenance materials. The filter circulation device 46 can be controlled by the signal processing center 31 according to the monitoring results of the water quality monitoring sensor 35 to pump the water in the lower part of the water storage device 21 that does not meet the water quality standards again to the upper part of the water storage device 21 for re-filtration. The movable gate 23 is used to control the connection or separation of the upper and lower parts of the water storage device 21 to ensure that the road drainage water can be fully filtered through the water treatment filter cartridge 45 in the upper part of the water storage device 21 before entering the lower part of the water storage device 21, and at the same time ensure that the materials will not be immersed in the water treatment filter cartridge 45 when the road maintenance materials are mixed.

[0056] In summary, this embodiment 1 realizes the effective removal of road surface water, cooling in high temperature environment and maintenance of road surface through the integrated device for road surface waterlogging removal, cooling and maintenance. The device quickly sucks in and transports road surface water through the coordinated work of the suction nozzle 11 and the two-way supercharger 13 in the conveying system 1, and further filters impurities and treats water quality by using the centrifugal filter 41 and the water treatment filter element 45 to ensure that the water quality meets the standard. The design of the water storage system 2 allows the accumulated water to be stored or directly discharged into the municipal pipeline, and automatically adjusts according to the road surface water situation, thereby improving the utilization efficiency of water resources. The sensor control system 3 monitors the road surface conditions in real time through the temperature-water level sensor 32, and transmits the data to the signal processing center 31 to achieve precise control of the device. The multiple filtering functions in the filtration system 4 ensure the high standard of water quality when spraying water for cooling and road surface maintenance materials are mixed. In addition, the design of the device also takes into account the convenience of operation and the automation of the system, reduces manual intervention, and improves operating efficiency and economic benefits. Through these comprehensive measures, this embodiment not only improves the service life of the road surface and driving safety, but also reduces maintenance costs, achieving the dual goals of environmental protection and economic benefits.

[0057] Example 2

[0058] Reference Figure 3-4 , which is the second embodiment of the present invention, provides a suction nozzle 11 with flexible switching of working states in an integrated device for pavement waterlogging removal, cooling and maintenance, which includes a water suction channel M, a spray channel N for spraying water or maintenance materials, a coarse-mesh filter 111, a movable cover plate 112, a spray component 113, and a control component 114.

[0059] Specifically, the water absorption channel M is in the inner circle and the spray channel N is in the outer circle, wherein the water absorption channel M is connected to the centrifugal filter 41, and above the water absorption channel M is a fixed coarse-mesh filter 111 for filtering impurities with larger particle sizes and a movable cover plate 112, and the spray channel N is connected to the water supply pipeline 12, and above the spray channel N is a fixed spray component 113, and a circle of spray holes are evenly distributed on the spray component 113, and these spray holes are of different sizes and arranged alternately, and the number of spray holes of different sizes and the spacing are the same, and below the fixed spray component 113 is a control component 114 for controlling the opening or closing of the two-size spray holes, and a circle of small holes are also evenly distributed on the control component 114, and the number of small holes is consistent with the number of large-aperture spray holes and small-aperture spray holes, and the control component 114 is controlled to rotate by a motor, and the motor is linked to the two-way supercharger 13.

[0060] Furthermore, the spray holes of large and small apertures on the spray component 113 are different only in the aperture at the upper end of the spray channel, and the aperture at the lower end is consistent with the aperture on the control component 114, and the radius of the circle where the spray holes at the upper end of the spray component 113 are located is larger than the radius of the circle where the holes at the lower end are located, so that water or curing materials are sprayed at a certain inclination angle to make the spraying more uniform.

[0061] Furthermore, when the suction nozzle 11 is absorbing water, the movable cover plate 112 tilts downward under the action of the water pressure and the two-way supercharger 13, so that the water on the road surface can be quickly discharged while preventing the generation of vortices to ensure driving safety. When not absorbing water, a spring is installed at the hinge of the movable cover plate 112 to make the movable cover plate 112 rebound to the horizontal position to maintain a closed state; when the suction nozzle 11 is spraying water for cooling, the control component 114 rotates to the water spraying state under the control of the motor, that is, the small hole on the control component 114 is connected to the small-aperture spray hole, at this time the large-aperture spray hole remains closed, and the cooling water is sprayed out through the small-aperture spray hole; when the suction nozzle 11 is spraying curing materials, the control component 114 rotates to the curing material spraying state under the control of the motor, that is, the small hole on the control component 114 is connected to the large-aperture spray hole, at this time the small-aperture spray hole remains closed, and the curing material is sprayed out through the large-aperture spray hole.

[0062] It should be noted that the suction nozzle 11 should be kept flush with the road surface when installed on the road surface to ensure the smoothness of the vehicle's driving and prevent adverse effects on the asphalt road surface.

[0063] In summary, the integrated road surface dewatering, cooling and maintenance device of this embodiment 2 realizes efficient and multifunctional road surface treatment through the innovative design of the suction nozzle 11. The water absorption channel M of the inner circle of the suction nozzle 11 is connected to the centrifugal filter 41, and cooperates with the coarse-mesh filter 111 and the movable cover plate 112 to quickly remove the surface water on the road when absorbing water, prevent the generation of vortexes, and ensure driving safety. The spray channel N of the outer circle is connected to the water supply pipeline 12. The spray holes of large and small apertures arranged alternately on the spray component 113 and the precise control of the control component 114 make it possible to evenly distribute water for cooling or spraying maintenance materials, thereby improving the effect. The design of the suction nozzle 11 allows automatic conversion under different working conditions, simplifies the operation process, reduces equipment wear, improves production continuity and road surface maintenance quality, reduces maintenance costs, and achieves a dual improvement in efficiency and economic benefits, while keeping the road surface flat and ensuring the comfort and safety of vehicle driving.

[0064] Example 3

[0065] Reference Figure 5-6, which is the third embodiment of the present invention, provides a centrifugal filter 41 in an integrated road surface waterlogging removal, cooling and maintenance device that integrates multiple mechanisms such as centrifugal force separation, mechanical movement and valve control, and water pressure and centrifugal force changes. The centrifugal filter 41 includes a pipeline 411, a fine-mesh filter screen 412, a limit cover plate 413, a rotating motor 414, a piston 415, and a piston track 416.

[0066] Specifically, the outer circle of the centrifugal filter 41 is a pipe 411 with a large number of limiting cover plates 413, and the inner circle is a fine-mesh filter 412 for filtering impurities with smaller particle sizes. A rotating motor 414 is installed at one end of the centrifugal filter 41. When draining water, the rotating motor 414 works to make the centrifugal filter 41 rotate at high speed. At this time, the limiting cover plate 413 opens under the action of centrifugal force, and the water therein passes through the fine-mesh filter screen 412 under the action of centrifugal force and is thrown out from the limiting cover plate 413, enters the water supply pipe 12, and is further transported to the water storage device 21, while the impurities in the water are filtered by the fine-mesh filter screen 412 and remain in the centrifugal filter 41.

[0067] Furthermore, when drainage of the road surface is being carried out, the movable valve 42 remains in a closed state to ensure that the water in the centrifugal filter 41 is smoothly thrown into the water supply pipe 12 by centrifugal force; after the drainage of the road surface is completed, the movable valve 42 is opened, and the piston 415 in the centrifugal filter 41 moves along the piston track 416 to clean the impurities to the end of the centrifugal filter 41, and then the movable valve 42 is opened and the solid impurity conveyor belt 43 starts working to transport the impurities to the solid impurity storage device 44.

[0068] It should be noted that the opening angle of the limit cover 413 in the centrifugal filter 41 does not exceed 90°. When draining water, it opens due to the water pressure and centrifugal force, allowing the water thrown out by the centrifugal force to enter the water pipe 12. When spraying water or curing materials, the direction of the water flow changes and the limit cover 413 is covered to prevent water or curing materials from entering the centrifugal filter 41.

[0069] In summary, the integrated road surface dewatering, cooling and maintenance device of this embodiment 3 realizes efficient separation of small-particle impurities through the ingenious design of the centrifugal filter 41. The filter uses the outer ring pipe 411, the inner ring fine-mesh filter 412 and the limit cover 413, combined with the high-speed rotation of the rotating motor 414, to use centrifugal force to throw water out of the limit cover 413, thereby filtering out impurities with smaller particle sizes. This design significantly reduces the impurity content of the water entering the water storage device 21 and extends the service life of the equipment. When the road surface is drained, the closing of the movable valve 42 ensures that the water is thrown out smoothly, and after the drainage is completed, the opening of the movable valve 42 cooperates with the piston 415 and the solid impurity conveyor belt 43 to achieve effective cleaning and transportation of impurities. The design of the limit cover 413 further ensures that when spraying water or curing materials, water or curing materials will not enter the centrifugal filter 41. The device simplifies the water treatment process, improves the continuity of production and the efficiency of water quality treatment, reduces maintenance costs, and ultimately achieves a dual improvement in production efficiency and economic benefits.
