[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

[0028] like Figure 1-4As shown, the rainwater treatment structure in the utility model is similar to the existing rainwater treatment structure, such as a rainwater treatment system for sponge city construction disclosed in the patent with publication number CN214574496U. The main improvement of the utility model is to clean up the garbage in the urban drainage, improve the smoothness of drainage, and ensure drainage during rainwater; when the utility model is draining, water falls into the drainage pipe 1 from the upper end of the drainage pipe 1, and the two shielding covers 8 prevent the water from directly entering the filter box 10. The water falling into the drainage pipe 1 first falls on the arc filter plate 4, and the arc filter plate 4 can filter the water and intercept debris, collect the debris in the water on the arc filter plate 4, and the debris will accumulate on both sides of the cleaning plate 12 to achieve filtration of the drainage, and the filtered water falls into the sewer 2 through the pipe 3, thereby avoiding debris. The phenomenon that the sewer 2 is blocked and affects the urban drainage is prevented; when a lot of debris is accumulated on the arc filter plate 4, the driving unit 5 is used to drive the cleaning plate 12 to rotate back and forth, so that the cleaning plate 12 pushes the debris on the arc filter plate 4 upward, and the perforations 18 on the cleaning plate 12 can leak water, so that the debris slides out of the arc filter plate 4 from the pores between the first partition plate 6 and the second partition plate 7, and the debris falls into the filter box 10. The filter box 10 is supported by the support bar 9. The filter box 10 collects the debris, and the water in the debris can leak from the filter box 10 into the drain pipe 1, so that the debris is cleaned and collected, and the drainage of the arc filter plate 4 is guaranteed, and the excessive accumulation of debris affects the drainage. The cleaning plate 12 can rotate back and forth, so that the cleaning plate 12 can clean the debris on both sides thereof, and ensure the urban drainage.

[0029] like Figure 1 , 2 As shown in Figure 4, a slide groove 16 is penetrated through the side wall of the cleaning plate 12, and the driving unit 5 includes a motor 51 installed on the outer wall of the drain pipe 1. The output shaft of the motor 51 penetrates into the drain pipe 1 and is fixedly connected to a rotating plate 52. One side of the rotating plate 52 is fixedly connected to an eccentric rod 53, and the eccentric rod 53 is penetrated in the slide groove 16 and is slidably connected thereto; when it is necessary to swing the cleaning plate 12 to clean the debris on the arc filter plate 4, the motor 51 is started, and the motor 51 drives the rotating plate 52 to rotate, and the rotating plate 52 drives the eccentric rod 53 to slide in the give way groove 13 on the cleaning plate 12, so that the cleaning plate 12 swings to clean the debris on the arc filter plate 4. The structure is simple, and only a conventional motor 51 is used for unidirectional rotation, which reduces the manufacturing cost.

[0030] Among them, the above-mentioned motor 51 can be purchased on the market. It is a mature technology and has been fully disclosed, so it is not repeated in the specification. The motor 51 is equipped with a power connection line, and it is electrically connected to the external main controller and 220V phase voltage (or 380V line voltage) through the power line, and the main controller can be a conventional known device such as a computer that plays a control role.

[0031] like Figure 2 As shown, a clearance groove 13 is opened on the inner wall of the drain pipe 1, and the rotating plate 52 is rotatably connected in the clearance groove 13; the clearance groove 13 makes way for the rotating plate 52 so that the rotating plate 52 does not protrude into the drain pipe 1, so that the width of the cleaning plate 12 is equal to the length of the parallel side of the inner wall of the drain pipe 1, so that when the debris is cleared from the arc filter plate 4, the debris will not be missed, thereby ensuring the cleaning of the debris.

[0032] like Figure 2 , 4 As shown, there are two yielding grooves 13 and two rotating plates 52, and the two rotating plates 52 are respectively located on both sides of the cleaning plate 12. The output shaft of the motor 51 is fixedly connected to the side wall of one of the rotating plates 52, and the two ends of the eccentric rod 53 are respectively fixedly connected to one side of the two rotating plates 52; the two rotating plates 52 can stably support the eccentric rod 53, thereby improving the stability of the cleaning plate 12 when subjected to force.

[0033] like Figure 2 As shown, the upper side wall of the first partition plate 6 and the side wall of the drain pipe 1 adjacent to the first partition plate 6 are provided with a mounting groove 11, and the shielding cover 8 is movably placed in the mounting groove 11; the shielding cover 8 can be taken out from the mounting groove 11, so as to facilitate taking the filter box 10 out from the support bar 9 to clean the debris inside it, and the mounting groove 11 can position the shielding cover 8 so that it can be placed stably.

[0034] like Figure 4 As shown, a brush strip 17 is embedded in the bottom surface of the lower end of the cleaning plate 12, and the brush strip 17 cleans the arc filter plate 4; when the cleaning plate 12 swings, the cleaning plate 12 can drive the brush strip 17 to slide on the arc filter plate 4, so that the brush strip 17 cleans the upper surface of the arc filter plate 4, thereby ensuring the cleanliness of the arc filter plate 4, avoiding blockage, and improving practicality.

[0035] like Figure 2 , 3 As shown, arc grooves 14 are provided on the inner walls on both sides of the drain pipe 1, and arc blocks 15 are fixedly connected to both sides of the lower end of the cleaning plate 12, and the arc blocks 15 are slidably connected to the arc grooves 14; when the cleaning plate 12 swings, the arc blocks 15 on both sides of its lower end slide in the arc grooves 14, and the arc grooves 14 limit the cleaning plate 12 through the arc blocks 15, thereby improving the strength of the cleaning plate 12.

[0036] like Figure 1 , 5 As shown, a SWMM model simulation system is also included, and a flow sensor 19 for sending data to the SWMM model simulation system is installed on the sewer 2;

[0037] When using the SWMM model to simulate rain and flood, the area needs to be divided into sub-catchments for simulation calculation. Each sub-catchment needs to correspond to a corresponding drainage system to calculate surface runoff, groundwater runoff, and underground pipe network water transfer.

[0038] Rainfall data: There are two types of rainfall data, including actual observed rainfall data and synthetic rainfall data. The synthetic rainfall data is obtained through the local rainstorm intensity formula combined with the Chicago rain type and is used in the model parameter calibration process based on the runoff coefficient.

[0039] Surface and underground drainage network data: including graphic data and related attribute data. Graphic data mainly includes surface rainwater pipe openings (wells), rainwater pipe connection nodes, rainwater pipe sections and surface channel spatial distribution. Attribute data includes the length, diameter, elevation, manhole depth, ground elevation and other information of water pipe sections, rainwater wells and network nodes.

[0040] Basic geographic data: mainly including ground cover types and digital elevation models of the study area, which assist in the discretization of sub-catchments and the calculation of related hydrological attribute parameters;

[0041] A complete set of engineering technology research methods for urban stormwater systems has been established, including data collection and processing, model building and parameter calibration, model verification and disaster assessment, model optimization and improvement, etc., providing technical support for the scientific analysis and evaluation of urban stormwater systems.

[0042] The SWMM model was optimized and improved, and uncertainty analysis and dynamic simulation methods were introduced to improve the robustness, adaptability, sensitivity and intelligence of the model, providing a new tool for dynamic management and decision-making of urban stormwater systems. The flow rate of sewer 2 was measured using flow sensor 19, and the SWMM model simulation system was used to ensure urban stormwater treatment.

[0043] The implementation steps in this embodiment are as follows: when draining water, water falls into the drain pipe 1 from the upper end thereof, and the two shielding covers 8 prevent the water from directly entering the filter box 10. The water falling into the drain pipe 1 first falls on the arc filter plate 4, which can filter the water and intercept debris, collect the debris in the water on the arc filter plate 4, and the debris will accumulate on both sides of the cleaning plate 12 to filter the drainage water. The filtered water falls into the sewer 2 through the pipe 3, thereby avoiding the phenomenon that the debris blocks the sewer 2 and affects the drainage of the city; when the arc filter When a lot of debris is accumulated on the plate 4, the motor 51 is started, and the motor 51 drives the rotating plate 52 to rotate, and the rotating plate 52 drives the eccentric rod 53 to slide in the yield groove 13 on the cleaning plate 12, so that the cleaning plate 12 swings, and the cleaning plate 12 pushes the debris on the arc filter plate 4 upward, so that the debris slides out of the arc filter plate 4 through the pores between the first partition plate 6 and the second partition plate 7, and the debris falls into the filter box 10, and the filter box 10 collects the debris, and the water in the debris can leak from the filter box 10 into the drain pipe 1, so that the debris is cleaned and collected.

[0044] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the claims of the present invention.
