Description

Technical Field

[0001] The present invention relates to the technical field of rainwater collection and utilization, and in particular to a rainwater collection and utilization device for highway engineering. Background Art

[0002] Rainwater harvesting and utilization is a technology and method that collects, stores and processes rainwater to achieve rational use of water resources. By setting up rainwater collection facilities such as rain barrels and reservoirs on building roofs, courtyards, squares and other areas, natural rainfall is collected. The collected rainwater undergoes a series of treatment processes such as filtration and sedimentation to remove impurities and pollutants so that it meets certain water quality standards. It can then be used for a variety of purposes, such as irrigating flowers, trees, flushing toilets, washing cars, and replenishing landscape water. It can even be used as part of industrial water after deep treatment. Rainwater harvesting and utilization not only helps alleviate the pressure of urban water shortage and reduce dependence on traditional water resources, but also reduces the pressure on urban drainage systems and alleviates flood disasters and soil erosion problems caused by rainwater runoff. It has significant economic, environmental and social benefits.

[0003] For a long time, most of the rainwater in highway projects has been discharged directly. Although this method can meet basic drainage needs, it is undoubtedly a waste of a large amount of water resources at the moment when the global water shortage situation is severe. Highways are widely distributed as infrastructure. Every time it rains, the road surface generates a considerable amount of rainwater. Directly discharging this rainwater means that precious water resources are not utilized at all, which runs counter to the concept of sustainable development. For example, in arid areas, there is a shortage of water for greening around highways, but a large amount of rainwater is lost in vain and cannot be used for irrigation, exacerbating the contradiction between water supply and demand. Based on this, a rainwater collection and utilization device for highway projects is proposed. Summary of the Invention

[0015] Beneficial effects of the present invention:

[0016] 1. In the present invention, by constructing a rainwater collection system, including drainage ditches, water delivery components, rainwater treatment components and rainwater storage tanks, etc., rainwater on the road surface can be collected and properly stored in the rainwater storage tank. At a time when water resources are becoming increasingly scarce, this effective way of collecting and storing rainwater realizes the resource utilization of rainwater.

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0033] Example 1

[0034] Reference Figures 1 to 10 , provides a rainwater collection and utilization device for highway engineering, including a drainage ditch 1 and a rainwater storage tank 3, a water supply component 7 and a rainwater treatment component 8 are installed between the drainage ditch 1 and the rainwater storage tank 3; the water supply component 7 is used to collect rainwater flowing out of the drainage ditch 1; the rainwater treatment component 8 is used to filter and treat rainwater flowing out of the rainwater drainage ditch 1; the water supply component 7 includes a water inlet component 71, a treatment component 72 and a water control component 73; the water inlet component 71 includes a water inlet well 711, and an upper side of the water inlet well 711 is connected to a water inlet pipe 712, one end of the water inlet pipe 712 is connected to the drainage ditch 1, and the bottom end of the water inlet well 711 is connected to a cylinder 713, and the cylinder 713 is connected to a first connecting pipe 714 and a first discharge pipe 715; the two ends inside the drainage ditch 1 are gradually lowered towards the position close to the water inlet pipe 712, so as to ensure that the water entering the drainage ditch 1 can smoothly enter the water inlet pipe 712.

[0035] Furthermore, the processing assembly 72 includes a processing box 721, which is fixedly connected to the wall of the rainwater storage tank 3. The bottom end of the processing box 721 is connected to a second discharge pipe 722. The inner side of the processing box 721 is fixedly connected with a first filter screen 724 and a second filter screen 725 from bottom to top. The processing box 721 is connected to a second connecting pipe 723 above the second filter screen 725. One end of the first connecting pipe 714 is connected to the processing box 721, and the connecting point is set below the first filter screen 724.

[0036] Furthermore, the water control assembly 73 includes a floating water tank 731, which is connected to the top of the rainwater storage tank 3. A floating plate 738 is provided in the floating water tank 731. One end of the second connecting pipe 723 is connected to the inside of the floating water tank 731, and the connecting point is set below the floating plate 738. The top of the floating plate 738 is fixedly connected to the first lifting rod 732. A first avoidance slot 736 for avoiding the first lifting rod 732 is opened on the wall of the floating water tank 731. The first lifting rod 732 is slidably arranged in the first avoidance slot 736. 36, one end of the first lifting rod 732 is fixedly connected to the vertical rack 733, and the cylinder body 713 is rotatably connected to the drain cylinder 737. One end of the drain cylinder 737 is provided with a water inlet hole 7371, and the side wall of the drain cylinder 737 is provided with a water outlet hole 7372. The other end of the drain cylinder 737 is fixedly connected to the horizontal rotation shaft 735. After the horizontal rotation shaft 735 passes through the cylinder body 713, it is fixedly sleeved with a gear 734. The gear 734 is engaged with the vertical rack 733, and the water outlet hole 7372 is provided corresponding to the first connecting pipe 714.

[0037] In the above, the drainage ditch 1 is set at a specific drainage position lower than the road surface in the highway project, and rainwater can pass through and enter the interior of the drainage ditch 1 smoothly. The rainwater entering the drainage ditch 1 will flow into the water inlet well 711 with the help of the connecting structure of the water inlet pipe 712, and then the rainwater will enter the cylinder 713 from the bottom end of the water inlet well 711. In the cylinder 713, the rainwater will flow in from the water inlet hole 7371 at one end of the drainage cylinder 737, and then flow out from the water outlet hole 7372 on its side wall, and then enter the first connecting pipe 714. At this time, the rainwater will pass through the first vertical valve plate 813 and the second flow hole 8131 horizontally penetrated on the first vertical valve plate 813, and smoothly enter the treatment box 721; in the treatment box 721, the rainwater will After undergoing a relatively fine filtration process, the inside of the treatment box 721 is fixedly connected with a first filter screen 724 and a second filter screen 725 from bottom to top. As the rainwater in the treatment box 721 continues to increase and the water level gradually rises, the rainwater will pass through these two layers of filter screens in turn. The first filter screen 724 can filter out relatively large particles of impurities in the rainwater, while the second filter screen 725 further filters out finer impurities, thereby effectively improving the purity of the rainwater. When the filtered rainwater rises to the height of the second connecting pipe 723, the rainwater will flow into the floating tank 731 through the third flow hole 8141 and the second connecting pipe 723, and then fall into the rainwater storage tank 3, thus completing the rainwater collection process.

[0038] In the above, during the rainwater collection process, the water control component 73 will automatically adjust the flow direction of rainwater according to the water level change in the floating water tank 731. The floating water tank 731 is connected to the top of the rainwater storage tank 3. When more and more rainwater is collected in the rainwater storage tank 3, the water level rises to the level of the floating water tank 731, and as the water level continues to rise, the floating plate 738 in the floating water tank 731 will float on the water surface under the action of buoyancy and move upward as the water level rises; the top of the floating plate 738 is fixedly connected to the first lifting rod 732, and the floating plate 738 moves upward. When the water tank 731 is moved, the first lifting rod 732 will be driven to slide upward along the first avoidance slot 736 opened on the wall of the float tank 731. One end of the first lifting rod 732 is fixedly connected to the vertical rack 733, so the rise of the first lifting rod 732 will synchronously drive the vertical rack 733 to move upward. In the cylinder 713, the other end of the drainage cylinder 737 is fixedly connected to the horizontal shaft 735. The horizontal shaft 735 passes through the cylinder 713 and is fixedly sleeved with a gear 734. The gear 734 and the vertical rack 733 are meshed with each other. Therefore, when the vertical rack 733 moves upward, The gear 734 is driven to rotate, and the rotation of the gear 734 drives the horizontal shaft 735 to rotate, thereby causing the drain cylinder 737 to rotate. During the rotation of the drain cylinder 737, the position of the water outlet hole 7372 on its side wall will change. When the water in the rainwater storage tank 3 is full and enters the floating tank 731, the floating plate 738 is raised to a certain height. As the drain cylinder 737 rotates, the water outlet hole 7372 will gradually correspond to the inlet end of the first discharge pipe 715. At this time, the rainwater will be discharged through the first discharge pipe 715, avoiding the rainwater storage tank 3 from being overfilled with rainwater. When the water level in the rainwater storage tank 3 decreases, the float 738 will move downward under the action of gravity. The descent of the float 738 will drive the first lifting rod 732 and the vertical rack 733 to move downward synchronously. The downward movement of the vertical rack 733 will drive the gear 734 to rotate in the opposite direction, thereby causing the drain cylinder 737 to rotate in the opposite direction, so that the water outlet 7372 corresponds to the first connecting pipe 714 again, so that rainwater can continue to be added to the rainwater storage tank 3, thereby realizing automatic control of whether to add rainwater according to the water level in the rainwater storage tank 3.

[0039] Example 2

[0040] Further, refer to Figures 1 to 12On the basis of the first embodiment, the rainwater treatment component 8 includes a control component 81, a drive component 82 and a flushing component 83; the control component 81 includes a vertical frame plate 811, and a horizontal valve plate 812, a first vertical valve plate 813 and a second vertical valve plate 814 are fixedly connected to one side of the vertical frame plate 811 from bottom to top in sequence. The horizontal valve plate 812 is longitudinally penetrated with a first flow hole 8121, the first vertical valve plate 813 is transversely penetrated with a second flow hole 8131, and the second vertical valve plate 814 is transversely penetrated with a third flow hole 8141. The horizontal valve plate 812 is sealed and slidably connected to the second discharge pipe 722, the first vertical valve plate 813 is sealed and slidably connected to the first connecting pipe 714, and the second vertical valve plate 814 is sealed and slidably connected to the second connecting pipe 723. A vertical guide groove 815 and an oblique guide groove 816 are penetrated on the vertical frame plate 811, and the top end of the vertical guide groove 815 is connected to the bottom end of the oblique guide groove 816.

[0041] Furthermore, the driving assembly 82 includes a fixed frame 821, which is fixedly connected to the box wall of the processing box 721. An electric cylinder 822 is fixedly connected to the fixed frame 821, and the electric cylinder 822 is electrically connected to an external control switch through a wire. The telescopic end of the electric cylinder 822 is fixedly connected to a fixed rod 823, and a guide wheel 824 is rotatably sleeved on the fixed rod 823 and is arranged at the inner top end of the inclined guide groove 816. One end of the fixed rod 823 is fixedly connected to a driving block 825.

[0042] Furthermore, the flushing assembly 83 includes an extrusion plate 834, which is slidably connected in the processing box 721. The top of the extrusion plate 834 is fixedly connected to the second lifting rod 831. The upper inner part of the processing box 721 is fixedly connected to a fixed block 832. The bottom of the fixed block 832 is fixedly connected to a spring 835. The bottom end of the spring 835 is fixedly connected to the top of the extrusion plate 834. The inner side of the processing box 721 is fixedly connected to a limiting protrusion 836. The limiting protrusion 836 is set at the top of the extrusion plate 834. A second avoidance slot 837 for avoiding the second lifting rod 831 is opened on the box wall of the processing box 721. The second lifting rod 831 is slidably connected in the second avoidance slot 837. One end of the second lifting rod 831 is fixedly connected to a pressure block 833. The top of the pressure block 833 is consistent in height with the top of the vertical guide groove 815.

[0043] In the above, as rainwater continuously enters the treatment box 721 for filtration, over time, a certain amount of impurities and sewage will be precipitated and accumulated under the first filter screen 724 in the treatment box 721. At this time, it is necessary to clean it. The cleaning operation mainly relies on the control component 81, the drive component 82 and the flushing component 83 in the rainwater treatment component 8 to complete the work together. After the electric cylinder 822 is started, the telescopic end of the electric cylinder 822 begins to extend, driving the fixed rod 823 to move downward. A guide wheel 824 is provided on the rotating sleeve of the fixed rod 823. The guide wheel 824 is set at the inner top of the oblique guide groove 816. In the process of the fixed rod 823 moving downward, the guide wheel 824 will move along the oblique guide groove 816 rolls downward, causing the guide wheel 824 to drive the vertical frame plate 811 to slide horizontally synchronously. Since the horizontal valve plate 812, the first vertical valve plate 813 and the second vertical valve plate 814 are fixedly connected to one side of the vertical frame plate 811 from bottom to top, the sliding of the vertical frame plate 811 will cause the horizontal valve plate 812 to slide on the second discharge pipe 722, the first vertical valve plate 813 to slide on the first connecting pipe 714, and the second vertical valve plate 814 to slide on the second connecting pipe 723. In this process, the second flow hole 8131 on the first vertical valve plate 813 will gradually stagger with the first connecting pipe 714, and finally the outlet end of the first connecting pipe 714 will be completely blocked by the first vertical valve plate 813. At the same time, the third flow hole 8141 on the second vertical valve plate 814 will also be staggered with the second connecting pipe 723, so that the inlet end of the second connecting pipe 723 is blocked by the second vertical valve plate 814, and the first flow hole 8121 longitudinally running through the horizontal valve plate 812 will gradually begin to correspond to the inlet end of the second discharge pipe 722. When the guide wheel 824 enters the vertical guide groove 815 from the bottom end of the oblique guide groove 816, the first flow hole 8121 just completely corresponds to the inside of the second discharge pipe 722, so that the impurities and sewage in the treatment box 721 can enter the second discharge pipe 722 through the first flow hole 8121. At this time, the telescopic end of the electric cylinder 822 continues to extend. The driving block 825 fixedly connected to one end of the fixed rod 823 will move downward. Since the driving block 825 is just in contact with the pressure block 833 at this time, the downward movement of the driving block 825 will push the pressure block 833 to move downward synchronously. The pressure block 833 is fixedly connected to one end of the second lifting rod 831, so the descending of the pressure block 833 will drive the second lifting rod 831 to slide downward along the second avoidance slot 837. The other end of the second lifting rod 831 is fixedly connected to the extrusion plate 834, and the extrusion plate 834 is slidably connected to the processing box 721. The bottom of the fixed block 832 fixedly connected to the upper inner side of the processing box 721 is connected to the top of the extrusion plate 834 through a spring 835.As the second lifting rod 831 drives the squeezing plate 834 downward, the spring 835 is elastically stretched, and the squeezing plate 834 applies pressure to the rainwater in the treatment box 721, causing the clean water above the second filter 725 to flow downward. Under the scouring action of the water flow, some impurities attached to the second filter 725 and the first filter 724 are removed. At the same time, impurities and sewage accumulated below the first filter 724 are discharged through the second discharge pipe 722 under the action of pressure and flow away into the underground drainage pipe. After cleaning is completed, the telescopic end of the control electric cylinder 822 is retracted, and the various components return to the opposite motion trajectory, allowing the subsequent rainwater collection work to continue.

[0044] Example 3

[0045] Further, refer to Figures 1 to 12 On the basis of the second embodiment, a protective box 4 is installed on the wall of the rainwater storage box 3, the water supply component 7 and the rainwater treatment component 8 are both installed in the protective box 4, and the bottom ends of the first discharge pipe 715 and the second discharge pipe 722 pass through the bottom of the protective box 4 and are connected to the underground drainage pipe.

[0046] Furthermore, a water intake pipe 6 is fixedly connected to the rainwater storage box 3, the bottom end of the water intake pipe 6 extends into the inner lower part of the rainwater storage box 3, and the top end of the water intake pipe 6 is connected to the water inlet end of the external water pump.

[0047] Furthermore, a mesh plate 2 is provided at equal intervals on the top of the drainage ditch 1 , and a plurality of water filtering holes 5 are evenly distributed through the mesh plate 2 .

[0048] In the above, a fixedly connected water intake pipe 6 runs through the rainwater storage tank 3, and its bottom end extends into the lower inner part of the rainwater storage tank 3. When the collected rainwater is needed, the external water pump is started to pump the rainwater in the rainwater storage tank 3 out through the water intake pipe 6 for use in highway greening irrigation, road cleaning and other purposes. In addition, the protection box 4 installed on the wall of the rainwater storage tank 3 covers the water supply component 7 and the rainwater treatment component 8 inside. The protection box 4 can prevent external factors such as dust and debris from damaging the water supply component 7 and the rainwater treatment component 8, thereby extending the service life of the device and ensuring stable operation of the device. The bottom ends of the first discharge pipe 715 and the second discharge pipe 722 pass through the bottom of the protection box 4 and are connected to the underground drainage pipe, ensuring the smooth discharge of excess rainwater and impurity sewage in the treatment box 721.

[0049] In the above description, when rainwater flows into the drainage ditch 1, it will first pass through the mesh plate 2 covering the top of the drainage ditch 1. There are a number of water filter holes 5 evenly distributed on the mesh plate 2. These water filter holes 5 can play a role of preliminary filtration, blocking larger particulate impurities in the rainwater, thereby preventing larger particulate impurities from entering the drainage ditch 1.

[0050] Reference Figures 1 to 12 The working principle of the rainwater collection and utilization device for highway engineering provided by the present invention is as follows:

[0051] When in use, the device is pre-buried and installed underground or a foundation pit is built for installing the device. The drainage ditch 1 is installed at a drainage position lower than the road surface in the highway project. Rainwater flows to the drainage ditch 1 through the road surface, and the larger particles of impurities are blocked above by the water filter holes 5 on the mesh plate 2 covering the top of the drainage ditch 1. The rainwater then enters the drainage ditch 1. The rainwater in the drainage ditch 1 enters the water inlet well 711 through the water inlet pipe 712, and then enters the cylinder 713 through the water inlet well 711. The rainwater entering the cylinder 713 enters through the water inlet hole 7371 of the drainage cylinder 737, and flows out through the water outlet hole 7372 of the drainage cylinder 737 into the first connecting pipe 714, and then The rainwater enters the treatment box 721 through the second flow hole 8131 on the first vertical valve plate 813. As the water level in the treatment box 721 rises, the rainwater is filtered through the first filter screen 724 and the second filter screen 725 in turn. After the filtered rainwater rises to the height of the second connecting pipe 723, it enters the rainwater storage tank 3 through the second connecting pipe 723, thereby collecting the rainwater through the rainwater storage tank 3. As more and more rainwater is collected in the rainwater storage tank 3, the water level in the rainwater storage tank 3 rises and enters the floating tank 731, causing the float 738 to float on the water surface. As the water level in the floating tank 731 continues to rise, the float 738 will also float. As the water level rises, the float 738 moves upward, driving the first lifting rod 732 to slide upward along the first avoidance slot 736. The first lifting rod 732 drives the vertical rack 733 to move upward synchronously. The vertical rack 733 drives the gear 734 to rotate, and the gear 734 drives the horizontal shaft 735 to rotate the drain cylinder 737. As the drain cylinder 737 rotates, the water outlet hole 7372 gradually corresponds to the inlet end of the first discharge pipe 715, so that rainwater is discharged through the first discharge pipe 715. In this way, after the water in the rainwater storage tank 3 is full, the water surface drives the float 738 to move upward, so that excess rainwater no longer enters the rainwater storage tank 3, and directly passes through the first discharge pipe 715 is drained away, and when the water in the rainwater storage tank 3 decreases, the floating plate 738 moves downward, thereby moving the vertical rack 733 downward to drive the gear 734 to rotate in the opposite direction, and then the drain cylinder 737 rotates in the opposite direction, so that the water outlet hole 7372 is aligned with the first connecting pipe 714 again, so that rainwater is added to the rainwater storage tank 3. Through the design of this structure, when the rainwater in the rainwater storage tank 3 is insufficient, the water outlet hole 7372 is aligned with the first connecting pipe 714, and rainwater can be added to the rainwater storage tank 3 first. When the rainwater in the rainwater storage tank 3 is full, the water outlet hole 7372 is aligned with the first discharge pipe 715, and the rainwater is directly discharged into the underground drainage pipe for drainage;When it is necessary to clean up the impurities and sewage below the first filter screen 724 in the treatment box 721, the electric cylinder 822 is started, and the telescopic end of the electric cylinder 822 extends to drive the fixed rod 823 to move downward, and the fixed rod 823 drives the guide wheel 824 and the driving block 825 to move downward synchronously. When the guide wheel 824 moves downward, it keeps moving in the inclined guide groove 816, so that the vertical frame plate 811 drives the horizontal valve plate 812, the first vertical valve plate 813 and the second vertical valve plate 814 to slide horizontally synchronously, so that the horizontal valve plate 812 slides in the second discharge pipe 722, and the first vertical valve plate 813 slides in the first connecting pipe 714. , the second vertical valve plate 814 slides in the second connecting pipe 723, so that the second flow hole 8131 of the first vertical valve plate 813 is staggered with the first connecting pipe 714, and the third flow hole 8141 of the second vertical valve plate 814 is staggered with the second connecting pipe 723. At this time, the first vertical valve plate 813 blocks the outlet end of the first connecting pipe 714, and the second vertical valve plate 814 blocks the inlet end of the second connecting pipe 723. At the same time, the first flow hole 8121 of the horizontal valve plate 812 begins to gradually correspond to the inlet end of the second discharge pipe 722, until the first flow hole 8121 is completely aligned with the inside of the second discharge pipe 722. At this time, the guide wheel 824 just enters the vertical guide groove 815 from the bottom end of the oblique guide groove 816, and the driving block 825 just contacts the pressure block 833. The telescopic end of the electric cylinder 822 continues to extend to make the driving block 825 move downward, and the guide wheel 824 remains in the vertical guide groove 815 and moves downward. The vertical frame plate 811 remains stopped. As the driving block 825 moves downward, the pressure block 833 is pushed downward synchronously. The pressure block 833 drives the second lifting rod 831 to move downward, and the second lifting rod 831 slides downward along the second avoidance slot 837. The second lifting rod 831 drives the extrusion plate 83 4 moves downward, the spring 835 is elastically stretched, and as the squeezing plate 834 moves downward, the rainwater in the processing box 721 exerts pressure, causing the clean water above the second filter screen 725 to flow downward, thereby cleaning out some impurities from the second filter screen 725 and the first filter screen 724. At the same time, the impurities and sewage below the first filter screen 724 are discharged through the second discharge pipe 722 to the underground drainage pipe. After cleaning is completed, the telescopic end of the electric cylinder 822 is controlled to retract and reverse the operation, thereby returning the vertical frame plate 811 to its original position, and subsequent rainwater collection can then be resumed.
