Description

Technical Field

[0001] The invention belongs to the technical field of sewage removal equipment, in particular to a sponge city rainwater and sewage decontamination and diversion device. Background Art

[0002] Sponge city refers to a new urban planning concept that builds wetlands, grasslands, green areas and other water storage places in the city to enhance the city's ability to store rainwater, thereby effectively alleviating the problem of urban waterlogging. Through the construction of sponge cities, cities can not only better cope with rainstorms, but also improve the ecological environment and enhance the quality of life of residents.

[0003] In the process of sponge city construction, the diversion and discharge of rainwater and sewage is a key link in achieving sustainable urban development. By building a complete drainage system, urban waterlogging can be effectively reduced, the utilization rate of water resources can be improved, and rainwater and sewage can be diverted and discharged, so that rainwater can be quickly discharged into lakes and wetlands, and sewage can flow into sewage treatment plants. On the one hand, it can reduce the operating burden of sewage treatment plants and effectively reduce the probability of waterlogging in rainstorms. On the other hand, the diversion and discharge system can also significantly improve the quality of urban water environment. Rainwater reduces the direct discharge of pollutants through the purification of natural water bodies, which helps to protect the ecological balance of lakes and wetlands. However, in the actual implementation process, it is found that although a complete sewage discharge system can achieve the diversion of rainwater and domestic sewage, there are still many incidents of sewage flowing into rainwater wells and rainwater pipes due to human factors, such as street cleaning wastewater, street shops, and stalls. The sewage generated during the operation is discharged into the rainwater pipe, or because of the difficulty of supervision, limited law enforcement, or the difficulty of sewage interception, the phenomenon of direct sewage discharge in the rainwater pipe often occurs.

[0004] In order to solve the above technical problems, a rainwater and sewage diversion device is disclosed in the related technology, and the application number is CN2023105728813. This scheme diverts the accumulated water into space one of the second collection box on sunny days or in the initial rain, and diverts the accumulated water into space two of the second collection box when there is more rain; it realizes the interception of domestic sewage and initial rainwater discharged on the street on sunny days into the sewage pipe network, and the mid- and late-stage rainwater enters the rainwater pipe network, thereby simply realizing the rainwater and sewage diversion of the drainage system. However, when the scheme is used for experimental simulation, it is found that since the rate at which the sewage flowing into the rainwater pipe is discharged into the sewage pipe is constant, while the discharge rate of rainwater or domestic sewage is unstable, when the domestic sewage discharge rate on the street or highway is too fast and the discharge amount is large, or when the rainfall on rainy days is small and the rainfall lasts for a long time, it will cause sewage to be discharged into the rainwater pipe or rainwater to be continuously discharged into the sewage pipe, resulting in a reduced degree of rainwater and sewage diversion, which not only increases the difficulty of sewage treatment, but also pollutes natural water bodies.

[0005] In view of this, the present invention proposes a sponge city rainwater and sewage decontamination and diversion device to solve the above technical problems. Summary of the invention

In addition, since the impurity sedimentation rate is relatively fast during the rainwater gathering process, the small amount of rainwater discharged into the sewage pipe has a higher impurity content. If it is not a rainy day, the valve plate will not move, and the opening degree of the through hole will gradually increase with the increase in sewage discharge, thereby meeting the sewage discharge. At the same time, since there is no water in the diversion chamber, the through hole is blocked under the action of the inclined plate and the elastic ring sheet at this time, which can also effectively reduce the probability of sewage backflow in the sewage pipe and a large amount of abnormal gas flowing into the diversion chamber.

DETAILED DESCRIPTION

[0038] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0039] like Figures 1 to 8 As shown, a rainwater and sewage decontamination and diversion device for a sponge city according to the present invention comprises a water collecting trough pipe 1, a diversion hub, a rainwater pipe 11 and a sewage pipe 12;

[0040] The water collecting trough pipe 1 is used to collect ground water. The water collecting trough pipe 1, the rainwater pipe 11, and the sewage pipe 12 are all connected to the diversion center, and the diversion center is used to divert rainwater and sewage;

[0041] The shunt center includes a shunt chamber 2, a drainage tube 21 and a detection tube 24;

[0042] The water collecting trough pipe 1 is connected to one side of the diversion chamber 2. Two groups of drainage pipes 21 are fixedly installed on the side of the diversion chamber 2 away from the water collecting trough pipe 1. The two groups of drainage pipes 21 are arranged in the vertical direction of the diversion chamber 2. The drainage pipes 21 are connected to the rainwater pipe 11 and the sewage pipe 12 respectively.

[0043] The drainage pipe 21 is commonly installed with an opening and closing valve shell 22, and a valve plate 23 is slidably installed in the opening and closing valve shell 22. The valve plate 23 is used to close the drainage pipe 21. The drainage pipes 21 corresponding to the rainwater pipe 11 and the sewage pipe 12 extend to the upper and lower ends of the opening and closing valve shell 22 respectively.

[0044] A detection tube 24 is fixedly installed on the top of the opening and closing valve housing 22. The detection tube 24 extends above the ground, and the top of the detection tube 24 is designed to be open;

[0045] A telescopic belt 25 is fixedly installed in the detection tube 24. The telescopic belt 25 is made of a water-swelling rubber material. The telescopic belt 25 extends into the opening and closing valve housing 22. The telescopic belt 25 is fixedly connected to the valve plate 23.

[0046] It also includes a slow-release component, which is used to slow down the rate at which the diversion chamber 2 drains outward.

[0047] In the rainwater and sewage diversion system of the sponge city, the drainage pipe is divided into a sewage pipe 12 and a rainwater pipe 11. Rainwater and sewage enter the rainwater pipe 11 and the sewage pipe 12 respectively, and are discharged into natural water bodies and sewage treatment plants respectively. Therefore, when sewage is mistakenly discharged into the rainwater pipe 11, it will directly pollute the natural water body. However, it is difficult to control domestic sewage and cleaning sewage pipes 12 in areas such as streets and roads, which often leads to accidents in which sewage is discharged into the rainwater pipe 11. In order to distinguish the discharged water, the present invention sets a diversion center to distinguish sewage and rainwater by jointly judging the weather conditions and the water volume, and divert them, thereby reducing the probability of sewage being discharged into the rainwater pipe 11.

[0048] Specifically, the water collection trough pipe 1 set up in the street pavement and highway area is used to gather and drain the surrounding flowing water, which is a basic facility of the road drainage project. No matter it is washing the road surface or splashing rainwater, the flowing water has a tendency to flow into the water collection trough pipe 1, and the flowing water is drained and discharged through the water collection trough pipe 1. During the flow, the flowing water is directly discharged into the diversion chamber 2. Since the diversion center includes a detection tube 24, the detection tube 24 extends above the ground and is opened, when it rains in the sky, the rainwater moves from top to bottom and can contact the telescopic belt 25 through the opening of the detection tube 24, so that the telescopic belt 25 absorbs water and expands. During the expansion process, the length of the telescopic belt 25 gradually increases, so that the valve plate 23 fixedly connected to the bottom end of the telescopic belt 25 descends, and the valve plate 23 descends in the opening and closing valve shell 22, so that the lower drainage pipe 21 is closed and the upper drainage pipe 21 is opened. The sewage pipe 12 is connected, and the drainage pipe 21 above is connected to the rainwater pipe 11. Therefore, when it rains, after the rainwater enters the diversion chamber 2 through the sump pipe 1, since the drainage pipe 21 corresponding to the sewage pipe 12 is in an open state in the initial state, part of the rainwater contaminated by rock and soil dirt flows into the sewage pipe 12. As the rainy day continues, the drainage pipe 21 corresponding to the rainwater pipe 11 is gradually opened, and the drainage pipe 21 corresponding to the sewage pipe 12 is gradually closed, so that the rainwater gradually gathers in the diversion chamber 2 and finally flows into the rainwater pipe 11. On non-rainy days, since street cleaning sewage and the like mostly flow horizontally from the road surface, the probability of sewage entering the detection tube 24 is small, so the telescopic belt 25 and the valve plate 23 are in a stable state, that is, the drainage pipe 21 corresponding to the rainwater pipe 11 is always closed, and the drainage pipe 21 corresponding to the sewage pipe 12 is always open, so that the sewage can be discharged into the sewage pipe 12, thereby realizing the diversion and discharge of rainwater and sewage.

[0049] The present invention is provided with a detection tube 24 extending above the ground, and a matching telescopic belt 25 and a valve plate 23. On non-rainy days, since the drainage pipe 21 corresponding to the rainwater pipe 11 is always closed, regardless of the sewage flow rate, it will be discharged into the sewage pipe 12. On rainy days, since the valve plate 23 will close the drainage pipe 21 corresponding to the sewage pipe 12, even if the rainfall is small, the rainwater can eventually flow into the rainwater pipe 11 under the continuous convergence effect. Compared with the prior art that distinguishes rainwater and sewage according to the amount of water, the present invention effectively enhances the accuracy of distinguishing rainwater from sewage according to the difference in the flow paths of rainwater and sewage, thereby reducing the probability of sewage flowing into the rainwater pipe 11.

[0050] As a preferred embodiment of the present invention, a liquid collecting bucket 26 is fixedly installed on the top of the detection tube 24, a conical plug 27 is fixedly installed on the end of the detection tube 24, the telescopic belt 25 passes through the conical plug 27 and extends to the inside of the liquid collecting bucket 26, and a liquid outlet hole 28 is opened at the bottom of the liquid collecting bucket 26.

[0051] The inner wall of the liquid collecting hopper 26 is a reflective layer. A heat collecting component 29 is fixedly installed in the liquid collecting hopper 26 . A heat conducting wire 2A is fixedly installed on the heat collecting component 29 . The heat conducting wire 2A extends to the inside of the telescopic belt 25 .

[0052] In order to further enhance the accuracy of judging whether it is a rainy day or a non-rainy day, and to maintain the use effect of the device, a liquid collecting hopper 26 with a liquid outlet 28 is provided in the present invention. In normal use, the setting of the funnel-shaped liquid collecting hopper 26 can effectively enhance the ability to collect water falling from the sky and guide the water toward the direction of the telescopic belt 25. When the water falling from the sky is rainwater, since the rainwater is continuous, the rainwater flows from the top of the liquid collecting hopper 26 to the bottom of the liquid collecting hopper 26, and finally passes through the liquid outlet 28. During the outflow process, the expansion belt 25 absorbs part of the water. As the rain continues, the expansion belt 25 continues to stretch, thereby changing the opening and closing state of the drainage pipe 21 corresponding to the rainwater pipe 11 and the sewage pipe 12. When the water falling from the sky is not rainwater, after excluding the intentional human factor, the probability of sewage being continuously sprayed above the liquid collecting bucket 26 is extremely small. Therefore, even in an unexpected situation, part of the sewage is sprayed into the liquid collecting bucket 26 and absorbed by the expansion belt 25, but the outlet hole The existence of 28 will make it flow out quickly. In the absence of continuity, the elastic band 25 absorbs less water, so it is not enough to drive the valve plate 23 to move through the deformation of the elastic band 25. At the same time, the opening of the liquid outlet hole 28 on the liquid collecting bucket 26 can also remove dust and impurities gathered in the liquid collecting bucket 26 through the flushing of rainwater in daily use. After the rain stops, the excess water in the liquid collecting bucket 26 quickly flows away and is reflected by the reflective layer of the liquid collecting bucket 26. Combined with the shape of the liquid collecting bucket 26, the water generated by the liquid collecting bucket 26 is Under the action of light, the light is gathered and converted into heat energy on the heat collecting member 29. The heat energy is transferred to the telescopic band 25 through the heat conductive wire 2A, causing the water absorbed by the telescopic band 25 to evaporate, thereby causing the valve plate 23 to rise and restore the opening and closing state of the drainage tube 21. It should be noted that the conical plug 27 is provided to prevent rainwater and dust from flowing into the detection tube 24. At the same time, the conical plug 27 is non-sealedly connected to the detection tube 24. Therefore, after the water in the telescopic band 25 evaporates, it can be discharged to the outside through the gap.

[0053] As a preferred embodiment of the present invention, a first floating plate 3 is slidably mounted on the detection tube 24 , and the liquid outlet 28 is located above the first floating plate 3 . The first floating plate 3 is used to prevent sewage from flowing back into the liquid collecting bucket 26 through the liquid outlet 28 .

[0054] A bellows expansion tube 24 is fixedly mounted on the first floating plate 3 , and a second floating plate 32 is fixedly mounted on one end of the bellows expansion tube 24 away from the first floating plate 3 . The diameter of the bellows expansion tube 24 is larger than the outer diameter of the liquid collecting hopper 26 .

[0055] In order to further improve the ability to judge sewage and rainwater and maintain the use effect of the device, the present invention is provided with a first floating plate 3 and a second floating plate 32. When the water level rises around the detection tube 24, as the water level rises, the first floating plate 3 is pushed up, and the first floating plate 3 is finally fitted with the bottom of the liquid collecting bucket 26, thereby reducing the probability of rainwater flowing back into the liquid collecting bucket 26 through the liquid outlet 28. If the water level continues to rise, the second floating plate 32 pulls the corrugated telescopic tube 24 to gradually expand. The expanded corrugated telescopic tube 24 is used to cover the liquid collecting bucket 26. On the one hand, it prevents sewage from flowing into the liquid collecting bucket 26. On the other hand, it can also protect the liquid collecting bucket 26, thereby preventing suspended impurities on the water surface from entering the liquid collecting bucket 26.

[0056] As a preferred embodiment of the present invention, it also includes a slow-release assembly, which is installed in the diversion chamber 2 and includes a slow-release valve body 4, a through hole 41 and a support block;

[0057] The slow-release valve body 4 is fixedly mounted at the bottom of the diversion chamber 2. A through hole 41 is formed on the slow-release valve body 4. The drainage pipe 21 corresponding to the sewage pipe 12 extends into the through hole 41.

[0058] A deflection groove 42 is provided on the slow-release valve body 4, and the deflection groove 42 is connected to the through hole 41. An inclined plate 43 is hingedly installed at the connection point between the deflection groove 42 and the through hole 41. A spring support rod 44 is fixedly installed in the deflection groove 42. In the initial state, multiple inclined plates 43 block the through hole 41.

[0059] An elastic ring piece 45 is commonly mounted on the plurality of inclined plates 43 , and the top end of the elastic ring piece 45 extends and is fixed on the inner wall of the through hole 41 .

[0060] When the flowing water flows into the diversion chamber 2 through the water collecting trough pipe 1, the flowing water gathers in the diversion chamber 2. As the water level in the diversion chamber 2 gradually increases, the elastic ring piece 45 and the inclined plate 43 gradually compress the spring support rod 44 under the action of water pressure, causing the through hole 41 to gradually open. At this time, if it is rainy, the slow opening of the through hole 41 provides a certain amount of time for the extension of the telescopic belt 25, which will make the amount of rainwater gathered in the diversion chamber 2 discharged to the sewage pipe 12 less, and because the rainwater is gathered, the amount of rainwater discharged to the sewage pipe 12 is less. During the process, the impurity sedimentation rate is relatively fast, so the small amount of rainwater discharged into the sewage pipe 12 has a high impurity content. If it is not a rainy day, since the valve plate 23 will not move, as the amount of sewage discharged increases, the opening degree of the through hole 41 gradually increases, thereby meeting the discharge of sewage. At the same time, since there is no water in the diversion chamber 2, the through hole 41 is blocked under the action of the inclined plate 43 and the elastic ring piece 45, and the probability of sewage backflow in the sewage pipe 12 and a large amount of abnormal gas flowing into the diversion chamber 2 can be effectively reduced.

[0061] As a preferred embodiment of the present invention, the diversion chamber 2 is composed of an inner cavity of a telescopic box, and the telescopic box includes an upper shell 5, a telescopic body 51 and a lower shell 52. The telescopic body 51 is used to connect the upper shell 5 and the lower shell 52. The upper shell 5 is fixedly installed in the inspection well through a bracket. A tension spring 54 is fixedly installed between the upper shell 5 and the lower shell 52, and the drainage pipe 21 is made of an elastic hose.

[0062] A limiting net 55 is fixedly mounted on the upper shell 5 , and the limiting net 55 is vertically arranged.

[0063] The diversion chamber 2 is composed of the inner cavity of the telescopic box. In the initial state, under the action of the tension spring 54, the upper shell 5 and the lower shell 52 are close to each other, so that the volume of the diversion chamber 2 is small. As the amount of water flowing into the diversion chamber 2 increases, under the action of water gravity, the volume of the telescopic box gradually increases. Therefore, on non-rainy days, the increase in the volume of the diversion chamber 2 can provide conditions for the temporary storage of sewage. On rainy days, the increase in the diversion chamber 2 can not only provide space for the temporary storage of rainwater and relieve the drainage pressure of the rainwater pipe 11, but also after the rain stops, as the water in the diversion chamber 2 decreases, the telescopic box gradually shrinks, and then the temporarily stored rainwater is discharged into the rainwater pipe 11. The amount of rainwater that finally flows into the sewage pipe 12 is less, and the limiting net 55 is used to intercept tiny suspended impurities in the water flowing into the diversion chamber 2, and cooperate with the sedimentation of impurities in the water in the diversion chamber 2 to reduce the probability of impurities in the water flowing into the rainwater pipe 11.

[0064] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
