Description

Technical Field

[0001] This application relates to the field of urban drainage systems, and particularly to a drainage pipe network component based on the concept of sponge city. Background Art

[0002] The concept of sponge city is a new urban rainwater management concept. Its core idea is to enhance the city's ability to absorb, store, and utilize rainwater through a combination of natural and artificial means, so as to achieve the natural accumulation, natural infiltration, natural purification, and sustainable utilization of urban rainwater.

[0003] With the acceleration of the urbanization process, the urban drainage system is facing more and more challenges. The traditional urban drainage system is based on underground pipes, which quickly drain rainwater into rivers or the sea. Although this method can solve the waterlogging problem in a short time, there are also many disadvantages. For example, the increase in surface runoff poses potential risks of urban waterlogging and water pollution, and the exclusion of rainwater will reduce the utilization rate of urban rainwater resources.

[0004] In the prior art, urban drainage pipe network components mainly focus on the rapid discharge of rainwater to avoid affecting ground traffic, while ignoring the collection and utilization of rainwater. Therefore, it is necessary to combine the concept of sponge city to design and improve the drainage pipe network components to improve the effective utilization rate of rainwater. Summary of the Invention

[0005] In order to improve the urban rainwater collection and storage capacity and promote the rational utilization of rainwater resources, this application provides a drainage pipe network component based on the concept of sponge city.

[0006] The drainage pipe network component based on the concept of sponge city provided by this application adopts the following technical solutions:

[0007] A drainage pipe network component based on the concept of sponge city includes a front-end pipe, and the front-end pipe is connected to a plurality of urban sewers. It further includes:

[0008] A pipe network, which is vertically arranged at one end of the front-end pipe connected to the urban sewer, and the bottom end is formed on the inner wall of the front-end pipe. The corresponding part of the front-end pipe to the pipe network is vertically arranged, and the top end of the pipe network is closed in an arc shape;

[0009] A delivery pipe, which is connected to the part of the front-end pipe corresponding to the bottom end of the pipe network, and the bottom end of the pipe network is inclined downward towards the delivery pipe;

[0010] An exhaust pipe, which is vertically arranged, the bottom end is connected to the delivery pipe, and the top end extends to the ground. An exhaust component is arranged inside the exhaust pipe for discharging solid pollutants to the ground;

[0011] The rear end pipe is connected to the front end pipe, and a filtering component is provided at the connection part for filtering small particle size pollutants.

[0012] By adopting the above technical solution, rainwater flows into the front end pipe and the rear end pipe along the urban sewer. The front end pipe and the rear end pipe are the main frameworks of the drainage pipe network. The exclusion pipe is used to exclude large particle size solid waste flowing into the drainage pipe network. The exclusion component is used to exclude the large particle size solid waste flowing into the drainage pipe network to the ground for collection and treatment by the cleaning staff; the filtering component is used to filter sludge and further filter groundwater to make the groundwater meet the discharge standard.

[0013] Optionally, the exclusion component includes:

[0014] An exclusion net, which is horizontally arranged and slidably connected to the inner wall of the exclusion pipe. A guiding groove is provided on the inner wall of the exclusion pipe corresponding to the exclusion net. A sliding plate is formed on the part of the exclusion net corresponding to the guiding groove, and the sliding plate is adapted to the guiding groove;

[0015] A driving member, which is arranged below the exclusion pipe and is used to drive the exclusion net to move upward.

[0016] By adopting the above technical solution, the exclusion net is arranged at the bottom end of the exclusion pipe. When solid waste is transported to the exclusion pipe along the conveying pipe and falls onto the exclusion net, the driving member operates regularly to make the exclusion net move upward, so that the exclusion net is close to the ground, which is convenient for the cleaning workers to clean.

[0017] Optionally, the driving member includes:

[0018] A connecting pipe, which is vertically arranged and has both ends connected to the bottom end of the exclusion pipe and the front end pipe to communicate the exclusion pipe and the front end pipe;

[0019] A first water pump, which is connected to the connecting pipe and is used to drive water to flow into the exclusion pipe.

[0020] By adopting the above technical solution, no fixing effect is applied to the exclusion net. Under normal circumstances, the exclusion net is horizontally arranged and a part of it extends into the guiding groove. When the first water pump pumps the water in the front end pipe upward into the exclusion pipe, after the water flow surges into the exclusion pipe, under the buoyancy effect, the exclusion net floats upward;

[0021] Under this scheme, even if the exclusion net does not float upward, the buoyancy of the water can also push most of the solid filter residues filtered by it to float upward;

[0022] The material of the filter net should be selected as a light material, and the mesh holes of the filter net should not be too large.

[0023] Optionally, it further includes:

[0024] The first valve is arranged at the connection part of the conveying pipe and the discharge pipe, and is used to block and connect the connection between the conveying pipe and the discharge pipe.

[0025] By adopting the above technical solution, when the floating filter net is removed in the above discharge pipe, the first valve needs to be closed to prevent solid filter residues from entering the conveying pipe and moving upward along the conveying pipe.

[0026] Optionally, it further includes:

[0027] The second valve is arranged at the connection of the front-end pipe and the rear-end pipe, and is used to block and connect the connection between the front-end pipe and the rear-end pipe.

[0028] By adopting the above technical solution, the second valve is used to block and connect the front-end pipe and the rear-end pipe. The second valve is normally closed. After a certain amount of accumulated water in the front-end pipe, the second valve is opened to make the front-end pipe and the rear-end pipe conduct. A certain amount of water needs to be accumulated in the front-end pipe to prevent the filter net from floating.

[0029] Optionally, the conveying pipe is inclined towards the end close to the discharge pipe.

[0030] By adopting the above technical solution, the conveying pipe is inclined to increase the sliding efficiency of solid pollutants.

[0031] Optionally, an infrared sensor is arranged at the connection of the discharge pipe and the conveying pipe, and a liquid level sensor is arranged at the part of the front-end pipe below the pipeline network.

[0032] By adopting the above technical solution, the liquid level sensor is used to detect the liquid level inside the front-end pipe and the rear-end pipe. Among them, the part of the front-end pipe below the pipeline network is used to detect the water volume inside the front-end pipe, and the infrared sensor between the discharge pipe and the conveying pipe is used to detect the amount of solid filter residues stored in the discharge pipe.

[0033] Optionally, the connection part of the front-end pipe and the rear-end pipe is perpendicular;

[0034] The filtering component includes,

[0035] A filter net is arranged at the connection part of the front-end pipe and the rear-end pipe, and is used to filter sludge;

[0036] The second water pump is arranged at one end of the front-end pipe close to the filter net, communicates with the discharge pipe, and pumps sludge into the discharge pipe.

[0037] By adopting the above technical solution, the filtering component removes the sludge in the water to make the water flow reach the discharge standard. The second water pump regularly pumps the sludge filtered by the filter net into the discharge pipe connected to the ground, and the mixed solid filter residues are regularly pumped by the cleaning staff.

[0038] In summary, the present invention has at least the following beneficial effects:

[0039] 1. Since the present invention is designed in combination with the sponge city concept, by setting up structures such as pipe networks, conveying pipes, and drainage pipes, the effective absorption, storage, and utilization of rainwater are realized, and the utilization rate of rainwater resources is improved.

[0040] 2. In the present invention, by setting up a drainage component and a filtering component, solid and small-particle pollutants are effectively treated, reducing the risk of urban water body pollution. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0044] The following Figure 1-2 further describes the present application in detail.

[0045] An embodiment of the present application discloses a drainage pipe network component based on the sponge city concept. Refer to Figure 1 , a drainage pipe network component based on the sponge city concept includes a front-end pipe 1 and a rear-end pipe 2. The front-end pipe 1 is buried underground and is vertically arranged. The top end of the front-end pipe 1 is connected to the sewer pipe inside the city and is connected to all sewer pipes in the area. Rainwater flows into the front-end pipe 1 and the rear-end pipe 2 through the sewer pipe. The front-end pipe 1 is composed of two perpendicular parts. One end connected to the sewer pipe is vertical, and one end connected to the rear-end pipe 2 is horizontal.

[0046] Refer to Figure 1 And Figure 2, on the inner wall of the vertical part of the front-end pipe 1, a pipe network 11 is fixedly connected. The pipe network 11 is vertically arranged. The main part of the pipe network 11 is cylindrical tubular. There is a gap between the wall of the pipe network 11 and the inner wall of the front-end pipe 1. The bottom end of the wall of the pipe network 11 is fixedly connected to the inner wall of the pipe network 11. The top end of the wall of the pipe network 11 bends towards the center to enclose the pipe network 11, making the whole pipe network 11 in the shape of a gong protruding upward from the center. The bottom end of the pipe network 11 is inclined to one side. The part where the sewage pipe communicates with the front-end pipe 1 is above the highest point of the bottom end of the pipe network 11. In this embodiment, a plurality of through holes are formed on the surface of the pipe network 11 for initially discharging a part of the sewage flowing from the sewage pipe into the front-end pipe 1.

[0047] In practical applications, the pipe network 11 is composed of a mesh plate material or woven into a mesh structure by metal wires, mainly for filtering large-particle solid waste.

[0048] Refer to Figure 2 , a through hole is bored through the inner wall of the front-end pipe 1 corresponding to the lowest point of the bottom wall of the pipe network 11, and a conveying pipe 12 is inserted. The conveying pipe 12 communicates with the front-end pipe 1 to convey the large-particle fixed objects filtered by the pipe network 11 through the conveying pipe 12.

[0049] Refer to Figure 2 , at one end of the conveying pipe 12 away from the front-end pipe 1, an exhaust pipe 3 is provided. The exhaust pipe 3 is vertically arranged, and the top end communicates with the ground. It communicates with the front-end pipe 1 through the conveying pipe 12. The conveying pipe 12 conveys the solid waste filtered by the front-end pipe 1 into the exhaust pipe 3. An exhaust component is arranged inside the exhaust pipe 3 to convey the garbage in the exhaust pipe 3 to the ground. The exhaust component includes an exhaust net 32. The exhaust net 32 is horizontally arranged at the bottom end of the exhaust pipe 3. The size of the exhaust net 32 is adapted to the exhaust pipe 3. Without hard restrictions on the exhaust net 32, the exhaust net 32 slides vertically along the exhaust pipe 3. At both ends of a diameter of the exhaust pipe 3, guide grooves 31 are vertically opened. The part of the edge of the exhaust net 32 corresponding to the guide grooves 31 is formed with sliders or slide plates adapted to the guide grooves 31 to prevent the exhaust net 32 from freely tilting and rotating, so that the exhaust net 32 slides vertically along the guide grooves 31. The solid waste conveyed to the exhaust pipe 3 through the conveying pipe 12 falls onto the exhaust net 32.

[0050] Refer to Figure 2 , the exhaust pipe 3 is arranged above the horizontal part of the front-end pipe 1. A connecting pipe 14 is arranged between the bottom end of the exhaust pipe 3 and the horizontal part of the front-end pipe 1. The connecting pipe 14 is vertically arranged to conduct the front-end pipe 1 and the exhaust pipe 3. A first water pump 17 is arranged on the connecting pipe 14. The first water pump 17 is used to pump the water in the front-end pipe 1 and convey the water into the exhaust pipe 3 to drive the exhaust net 32 to rise by buoyancy until the exhaust net 32 rises to the ground, and the cleaning staff cleans the solid waste above the exhaust net 32. Therefore, in this embodiment, it is necessary to rely on buoyancy, that is, the exhaust net 32 is composed of a light material.

[0051] In actual applications, most of the solid garbage flowing into the city sewers is light garbage such as leaves and packaging. Even if the removal net 32 ​​does not float up under the action of buoyancy, the light garbage above the removal net 32 ​​can float up and be cleaned up by cleaning staff.

[0052] Reference Figure 2 A first valve 15 is provided at the portion where the delivery pipe 12 is connected to the drainage pipe 3, which is used to control the opening and closing of the delivery pipe 12 and the drainage pipe 3. When the drainage net 32 ​​in the drainage pipe 3 floats up, the first valve 15 is closed to prevent water and garbage in the drainage pipe 3 from entering the delivery pipe 12.

[0053] Reference Figure 2 The part where the front end pipe 1 is connected to the rear end pipe 2 is perpendicular, that is, the rear end pipe 2 is vertically arranged to connect one end of the front end pipe 1, and a second valve 16 is arranged at this part of the front end pipe 1. The second valve 16 is in a normally closed state, blocking the front end pipe 1 and the rear end pipe 2, so that the front end pipe accumulates enough water to eliminate the floating of the component.

[0054] Reference Figure 2 The connecting part between the front end pipe 1 and the rear end pipe 2 is fixedly connected, and a filter screen 13 is obliquely arranged. A plurality of filter holes are pierced on the filter screen 13. The aperture of the filter holes on the filter screen 13 is smaller than the aperture of the filter holes on the pipeline network 11, and is used to filter out sludge and small-sized impurities mixed with the sludge.

[0055] Reference Figure 2 A second water pump 18 is provided at the portion where the front end pipe 1 is connected to the rear end pipe 2 . The second water pump 18 is connected to the discharge pipe 3 to extract the sludge filtered by the filter screen 13 into the discharge pipe 3 .

[0056] In order to monitor the operation process of the drainage component, this embodiment is provided with a liquid level sensor at the part of the front end pipe 1 below the pipeline network 11, and an infrared sensor is provided at the connecting part of the discharge pipe 3 and the delivery pipe 12, which are used to monitor the stored water volume inside the front end pipe 1 and the garbage storage volume in the discharge pipe 3 respectively.

[0057] The implementation principle of a drainage network component based on the sponge city concept in an embodiment of the present application is as follows: the management personnel observes the water storage volume of the front-end pipe 1 through a liquid level sensor, and when the water storage reaches a preset amount, the second valve 16 is opened, and the water flows through the filter net 13 to filter out the sludge, and then the second water pump 18 draws the sludge into the drainage pipe 3 and temporarily stores it in the drainage pipe 3.

[0058] When the management personnel learn through the infrared sensor that the garbage storage volume in the discharge pipe 3 reaches the value that needs to be discharged, first, the extraction device on the ground extracts the sludge and mud in the filter net 13 through the hose, and then the first water pump 17 operates to pump the water in the front-end pipe 1 into the discharge pipe 3. Under the buoyancy effect, the discharge net 32 does not float upward, and the light garbage above the discharge net 32 can float upward and is cleaned by the cleaning personnel.

[0059] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
