Description

Technical Field

[0001] This application relates to the technical field of riverbank water circulation, and in particular to a structure for rainwater circulation in riverbanks. Background Technology

[0002] Rapid urbanization has led to an increase in impermeable areas and rainwater runoff, placing greater pressure on river embankments for flood control. The rainwater cycle along river embankments is a complex process involving both natural and human intervention, impacting embankment safety, the rational use of water resources, and the protection of the ecological environment. Installing rainwater harvesting systems near river embankments allows for the collection of rainwater for irrigation, urban sanitation, and other purposes, achieving water resource reuse.

[0003] The structure of the riverbank rainwater circulation system includes a collection pipe and a transfer box installed on the riverbank. The transfer box is buried inside the riverbank, and the collection pipe is connected to the transfer box. One end of the collection pipe extends out of the slope. When it rains, the river water rises to a certain height and enters the transfer box through the collection pipe. The transfer box is connected to the urban sewage treatment system, so the rainwater can be further purified and treated to gain more utilization value.

[0004] Regarding the aforementioned technologies, the river water level is not easy to rise under normal circumstances, there is a gap between the collection pipe and the river water, and the collection pipe opening is exposed to the outside for a long time. Although a filter screen is usually installed at the collection pipe opening, debris is easy to accumulate at the collection pipe opening. Utility Model Content

[0005] To address the aforementioned problems, this application provides a structure for rainwater circulation in river embankments.

[0006] This application provides a structure for rainwater circulation in river embankments, employing the following technical solution:

[0007] A structure for rainwater circulation on riverbanks includes a transfer box and a collection pipe. A filter plate is installed at the water collection end of the collection pipe. A cavity is provided inside the filter plate. A first filter hole is distributed on the side of the filter plate near the water collection end. A second filter hole is provided on the bottom wall of the filter plate. The first filter hole and the second filter hole are connected through the cavity.

[0008] By adopting the above technical solution, rainwater can first enter the cavity through the second filter hole, and then flow into the collection pipe through the first filter hole, thus achieving two-stage filtration of rainwater. This effectively improves the filtration effect of rainwater, reduces the possibility of impurities entering the collection pipe, and when the collection pipe is idle, the second filter hole will not be directly exposed to the outside, preventing external impurities from easily entering the collection pipe.

[0009] Optionally, multiple cavities are provided, and the filter plate has a connecting hole between two adjacent cavities.

[0010] By adopting the above technical solution, multiple cavities are set inside the filter plate, and connecting holes are opened between adjacent cavities. This design allows rainwater to flow more evenly within the filter plate, avoiding the problem of a decrease in overall filtration efficiency due to blockage of a single cavity, and further improving the filtration efficiency and stability of rainwater.

[0011] Optionally, the filter plate has a sealing element that slides within the cavity to block the first filter hole, and the sealing element floats up when it comes into contact with water.

[0012] By adopting the above technical solution, when rainwater enters the cavity, the sealing component floats up due to buoyancy, which can automatically open the first filter hole.

[0013] Optionally, the sealing component is a float rod, with a first limiting block connected to the lower end of the float rod and a second limiting block connected to the upper end of the float rod. When the second limiting block abuts against the filter plate, the float rod and the first limiting block seal the cavity.

[0014] By adopting the above technical solution, when the float rises to the point where the first limiting block and the filter plate abut, the second filter hole is fully opened. When the second limiting block and the filter plate abut, the float blocks the second filter hole and the cavity. This design is not only simple in structure, but also can stably achieve the sealing function and ensure the filtration effect of rainwater.

[0015] Optionally, a filter element is installed inside the collection tube.

[0016] By adopting the above technical solution, rainwater entering the collection pipe can be filtered again, further improving the purity of the rainwater and facilitating its subsequent recycling.

[0017] Optionally, the filter element includes a mounting frame and particles filled within the mounting frame for filtration.

[0018] By adopting the above technical solution, filter particles of different sizes can be selected as needed to meet the filtration requirements of different scenarios, thereby improving the flexibility and applicability of filter components.

[0019] Optionally, multiple filter elements are installed along the length of the collection tube.

[0020] By adopting the above technical solutions, the filtration effect of rainwater can be further improved, ensuring the purity of rainwater, and also helping to extend the service life of the collection pipe.

[0021] Optionally, the filter plate can be detachably installed on the collection pipe.

[0022] By adopting the above technical solution, this design facilitates the cleaning and replacement of the filter plates, reduces maintenance costs, and improves the reliability and service life of the equipment.

[0023] Optionally, a mounting rod is installed on the filter plate, and the filter element is mounted on the mounting rod.

[0024] By adopting the above technical solutions, not only is the installation and disassembly of filter elements more convenient, but the position and quantity of filter elements can also be adjusted as needed, improving the flexibility and applicability of the equipment.

[0025] In summary, this application includes at least one of the following beneficial effects:

[0026] 1. Improved rainwater filtration efficiency and quality: Through multiple filtration and sealing designs, the possibility of impurities entering the collection pipe is effectively reduced, improving the purity and filtration efficiency of rainwater;

[0027] 2. The design features such as detachable filter plates and adjustable filter element positions and quantities, enabling the equipment to adapt to the filtration needs of different scenarios and improving its flexibility and applicability. Attached Figure Description

Detailed Implementation

[0036] The following is in conjunction with the appendix Figure 1 -Appendix Figure 7 This application will be described in further detail.

[0037] This application discloses a structure for rainwater circulation in river embankments. (Refer to...) Figure 1 A structure for rainwater recycling in river embankments includes a transfer box 10 and a collection pipe 20 installed within the embankment. The inlet of the collection pipe 20 is inclined upwards. The transfer box 10 and the collection pipe 20 are buried within the embankment during its construction. The transfer box 10 is connected to the urban sewage treatment system via a water pump and a water delivery pipe. The transfer box 10 is also connected to a drain pipe 30, which is inclined downwards. One end of the drain pipe 30 extends out of the slope and is located below the collection pipe 20. If the river water level is lower than normal, the treated sewage enters the transfer box 10 and is discharged, which is beneficial to maintaining the riverbank ecological environment.

[0038] Reference Figure 2 and Figure 3 A filter plate 40 is inserted into the water collection end of the collection pipe 20. The filter plate 40 is connected to an insert plate 45, which is used to connect with the end face of the collection pipe 20. First filter holes 41 are distributed on the side of the filter plate 40 near the water collection end of the collection pipe 20. Second filter holes 42 are opened on the circumferential side wall of the filter plate 40, and are spaced apart along the circumference of the filter plate 40. A cavity 43 is provided inside the filter plate 40, and both the first filter holes 41 and the second filter holes 42 communicate with the cavity 43. During heavy rain, after the river water level rises, the river water above the normal level passes through the second filter holes 42, the cavity 43, and the first filter holes 41 in sequence before entering the collection pipe 20. The filter plate 40 can provide a preliminary filtration effect on the river water.

[0039] Reference Figure 4 Multiple cavities 43 are provided. In this application, four cavities 43 are provided at intervals. The filter plate 40 has a connecting hole 44 between the inner walls of two adjacent cavities 43.

[0040] Reference Figure 3 and Figure 4 The filter plate 40 has a two-half spliced ​​structure, which facilitates the processing of the cavity 43 and the connecting hole 44.

[0041] Reference Figure 2 and Figure 4A sealing element for sealing the first filter hole 41 is slidably mounted inside the cavity 43. This sealing element includes a float 50, which is located within the cavity 43, with the side of the float 50 closest to the first filter hole 41 contacting the inner wall of the cavity 43. The float 50 is made of a buoyant material, such as foam or plastic. When the float 50 rises due to the buoyancy of the water, its upper end extends upwards outside the cavity 43. A first limiting block 51 is connected to the lower end of the float 50, which remains within the cavity 43, preventing the float 50 from leaving the filter plate 40. When the rising river water returns to its normal level, the float 50 moves downwards under its own weight. A second limiting block 52 is connected to the upper end of the float 50, which remains outside the filter plate 40. When the second limiting block 52 contacts the filter plate 40, the float 50 stops moving downwards. When the second limiting block 52 comes into contact with the filter plate 40, the float 50 blocks all the first filter holes 41.

[0042] Reference Figure 4 and Figure 5 When the filter plate 40 is idle, in order to reduce the amount of debris entering the cavity 43 from the second filter hole 42, the float 50 is attached to the side wall of the second filter hole 42 and the inner wall of the cavity 43. When the filter plate 40 is installed on the collection pipe 20, one end of the second filter hole 42 on the left and right side walls of the filter plate 40 is inclined downward, which can further reduce the amount of debris entering the cavity 43.

[0043] Reference Figure 6 A filter element is installed inside the collection pipe 20. The filter element includes a mounting frame 60 and granules filled inside the mounting frame 60 for filtration. The mounting frame 60 has a frame body and a filter screen. The frame body is used to contact the inner wall of the collection pipe 20, and the filter screen is installed at both ends of the frame body. The granules are gravel 61, which are filled inside the mounting frame 60. The filter element can further filter the river water.

[0044] Reference Figure 7 Multiple filter elements are installed along the length of the collection pipe 20. To securely mount the filter elements together, a mounting rod 80 is connected in series between the multiple mounting frames 60. The mounting rod 80 is connected to the filter plate 40. Nuts 81 are threaded onto the mounting rod 80, and multiple nuts 81 are spaced apart on the mounting rod 80. A filter element is installed between two nuts 81. The mounting rod 80 passes through the filter plate 40 and is fixed to the filter plate 40 by the nuts 81. The cooperation between the filter plate 40 and the filter elements ensures that the filter elements are stably installed inside the collection pipe 20, and the filter plate 40 is stably installed at the opening of the collection pipe 20.

[0045] The implementation principle of a structure for rainwater circulation in river embankments according to an embodiment of this application is as follows:

[0046] Heavy rainfall causes the river water to rise, causing the sealing component to float upwards. The cavity 43 connects to the first filter hole 41 and the second filter hole 42. The river water passes through the filter plate 40 and then enters the collection pipe 20. The filter component further filters the river water, enhancing the rainwater filtration effect. After the river water level drops, the sealing component moves downwards, sealing the cavity 43, making it difficult for debris to enter the filter plate 40.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
