[0002] The assembled road intercepting and filtering rainwater inlet is a facility for collecting, discharging and filtering rainwater on the road, which has the advantages of convenient construction and stable quality.

[0003] At present, open rainwater inlets are generally used in urban road pipe networks, and surface runoff is directly discharged into the drainage system through the rainwater inlets and flows into the river. With the rapid development of cities, the disadvantages of open rainwater inlets in the operation process of road pipe networks gradually appear, so there is a need for an assembled road intercepting and filtering rainwater inlet structure that can intercept large solid waste and cannot separate rainwater and sewage. However, when the existing assembled road intercepting and filtering rainwater inlet structure is used in heavy rain or rainstorm, a large amount of debris is carried in the rainwater, which causes the assembled road intercepting and filtering rainwater inlet structure to be blocked, and the assembled road intercepting and filtering rainwater inlet structure needs to be cleaned. Since the filtering structure in the assembled road intercepting and filtering rainwater inlet structure has only one working area, the assembled road intercepting and filtering rainwater inlet structure cannot work normally when cleaning, which causes the rainwater on the road to accumulate on the road for a long time, causing urban flooding. In addition, when the filtering structure is cleaned, the filtering structure needs to be taken out of the assembled road intercepting and filtering rainwater inlet structure. In order to avoid the rainwater carrying large-sized debris directly into the sewage pipe and causing the sewage pipe to be blocked, the surrounding of the drainage inlet needs to be blocked, which increases the operation steps and difficulty of cleaning.

[0004] Therefore, it is urgent to provide an assembled road intercepting and filtering rainwater inlet structure that can work continuously and reduce the difficulty of cleaning. SUMMARY

[0005] Therefore, it is necessary to provide an assembled road intercepting and filtering rainwater inlet structure to solve the problems that the existing assembled road intercepting and filtering rainwater inlet structure cannot work normally when cleaning and the filtering structure causes the sewage pipe to be blocked when cleaning.

DETAILED DESCRIPTION

[0032] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0033] See Figures 1-4 A prefabricated road drainage and rainwater inlet structure comprises a concrete shell 1, wherein a stepped supporting protrusion 10 is provided at the upper opening of the concrete shell 1.

[0034] During the specific work, the concrete shell 1 is transported to the construction site through existing transportation equipment, an installation pit is dug on the ground of the construction site, and then the concrete shell 1 is lifted into the pit through the existing crane, and then the lower ends of the concrete shell 1 are connected to the existing sewage pipe.

[0035] See Figure 1 、 Figure 4 and Figure 5 The assembled road interception and drainage rainwater inlet structure also includes an inner tank unit 2 placed in the concrete shell 1, and the inner tank unit 2 includes an inner tank frame 20 placed in the concrete shell 1. The inner tank frame 20 is a rectangular structure with an opening at the upper end. The frame wall of the inner tank frame 20 is provided with a plurality of evenly distributed drainage holes 21 near the lower end. Two symmetrically distributed grille cover plates 22 are placed on the upper end of the inner tank frame 20. A plurality of filter elements 4 are placed on the upper end of the bottom of the inner tank frame 20, and the plurality of filter elements 4 are respectively fitted with the lower sides of the inner surfaces of the plurality of frame walls of the inner tank frame 20.

[0036] See Figure 4 and Figure 5A drainage channel 5 is provided between the concrete shell 1 and the wall of the inner liner frame 20 .

[0037] During the specific work, before installing the inner liner frame 20, multiple filter elements 4 are first installed on the lower side of the inner surface of the inner liner frame 20, so that the multiple filter elements 4 are in close contact with the inner walls of the inner liner frame 20. Under the condition of light rain, the filter element 4 filters and absorbs pollutants in the rainwater to prevent silt from mixing into the discharge flow. Then the inner liner frame 20 is placed in the concrete shell 1. The supporting protrusion 10 at the upper end of the concrete shell 1 supports and limits the upper end of the inner liner frame 20. After the inner liner frame 20 is placed, a drainage channel 5 for drainage is formed between the concrete shell 1.

[0038] See Figure 4 、 Figure 5 and Figure 6 The assembled road interception and drainage rainwater inlet structure also includes a filter unit 3 arranged in the inner liner frame 20, and the filter unit 3 includes a support platform 30 installed in the middle of the inner surface of the frame wall of the inner liner frame 20, and a spoiler 31 is placed on the upper end of the support platform 30. The spoiler 31 includes a spoiler 310 placed on the upper end of the support platform 30, and a partition plate 311 is installed in the middle of the upper end of the spoiler 310. The partition plate 311 is provided with a plurality of evenly distributed filter holes 312.

[0039] During specific operation, the support platform 30 is fixedly connected to the inner wall of the inner liner frame 20 by welding or snapping. After the inner liner frame 20 is installed, the spoiler 310 is placed on the upper end of the support platform 30. The spoiler 310 drives the partition plate 311 to move into the inner liner frame 20 at the same time. The spoiler 310 has multiple strip-shaped through holes for drainage.

[0040] See Figure 6 、 Figure 7 and Figure 8 The spoiler 31 also includes two placement openings 313 symmetrically opened on the spoiler 310. The spoiler 310 is clamped with a limiting member 314 located at the placement opening 313. The limiting member 314 is an inverted "X"-shaped plate structure. A penetration hole 315 is opened on the bottom wall of the limiting member 314, and a locking hole 316 is opened on the two vertical sections of the limiting member 314 adjacent to the bottom wall.

[0041] In specific operation, after the spoiler 310 is installed, the two limiting members 314 are placed in the two placement openings 313, and the limiting members 314 are snap-fitted with the spoiler 310 through the placement of the buckles.

[0042] See Figure 5 、 Figure 6 、 Figure 7 、 Figure 9 and Figure 10Two symmetrically distributed filter parts 32 are placed on the spoiler 31. The filter part 32 includes a dirt shielding frame 320 placed on the upper end of the spoiler 310. A plurality of evenly distributed filter holes 321 are opened on the bottom wall of the dirt shielding frame 320. A limit frame 322 is installed on the upper end of the dirt shielding frame 320. A plurality of filter plates 323 are arranged on the outside of the limit frame 322. The lower end of the filter plate 323 is hinged to the upper end of the dirt shielding frame 320, and the plurality of filter plates 323 in a vertical state are tightly attached to each other.

[0043] See Figure 7 and Figure 9 The filter portion 32 further includes a lifting rod 324 that penetrates and is rotatably connected to the middle of the bottom wall of the dirt shielding frame 320 , and a limiting plate 325 is installed at the lower end of the lifting rod 324 .

[0044] In specific operation, after the limiting member 314 is placed, the two filter parts 32 are placed on both sides of the partition plate 311 respectively. When the filter part 32 is placed, the dirt shielding frame 320 is first fitted with the upper end of the spoiler 310, and the dirt shielding frame 320 drives the four filter plates 323 to move to the inner liner frame 20. The inner liner frame 20, the partition plate 311 and the limiting frame 322 cooperate to make the four filter plates 323 in a vertical state and close to each other, ensuring that rainwater can only pass through the four filter plates 323. The dirt-blocking frame 320 is placed while the limiting plate 325 is driven to pass through the penetration hole 315 by the lifting rod 324. Two limiting rings are installed in the middle of the lifting rod 324 and are distributed on the upper and lower sides of the bottom wall of the dirt-blocking frame 320. The limiting rings limit the vertical direction of the lifting rod 324. After the two filter parts 32 are placed, the two grille cover plates 22 are covered to the upper end of the inner tank frame 20 and the inner tank frame 20 is limited.

[0045] See Figure 4-Figure 6 The inner tank unit 2 also includes two louver parts 1 23 arranged on two symmetrical frame walls of the inner tank frame 20 and two louver parts 2 24 on another two symmetrical frame walls. The louver parts 1 23 and the louver parts 2 24 have the same structure and only differ in size.

[0046] See Figure 4-Figure 6 The louver portion 23 includes a mounting hole 230 opened on the frame wall of the inner tank frame 20, and a plurality of rotating shafts 231 evenly distributed from top to bottom are installed in the mounting hole 230, and the louver plates 232 are rotatably connected to the rotating shafts 231.

[0047] During specific operation, under normal conditions, multiple louvers 232 fit together through their own gravity to achieve the function of sealing the installation hole 230, preventing mosquitoes and polluted gases from being discharged from the sewage pipe. When it rains lightly, rainwater carries dead branches, leaves, plastic and other debris to move toward the concrete shell 1. The grille cover 22 filters the larger debris in the rainwater once. The filtered rainwater enters the two filter parts 32 in the inner liner frame 20 through the grille cover 22. The dirt blocking frame 320 filters the rainwater for a second time. The rainwater falls to the lower end of the inner liner frame 20 through the second filter hole 321, and then passes through multiple filter elements 4 for three filtrations and is discharged from the drainage hole 21. At this time, the rainwater is not enough to push open the louver 232.

[0048] During heavy rain or rainstorm, a large amount of rainwater instantly flows into the concrete shell 1. The second filter hole 321 on the dirt retaining frame 320 is not enough to quickly drain the large amount of rainwater. As time goes by, the debris components accumulate on the second filter hole 321, causing the rainwater to gradually accumulate between the multiple filter plates 323. As the rainwater accumulates, the pressure exerted by the rainwater gradually pushes the multiple louvers 232 open, ensuring that the rainwater is quickly discharged from the drainage channel 5. As the drainage time increases, the debris in the rainwater is gradually discharged. The debris gradually accumulates between the multiple filter plates 323 and the dirt shielding frame 320, resulting in clogging of the filter portion 32. At this time, the sanitation worker needs to perform a dirt cleaning process. During the dirt cleaning process, first remove a grille cover 22 from the upper end of the inner tank frame 20, then hold the lifting rod 324 and pull it upward. The lifting rod 324 drives the dirt shielding frame 320, the multiple filter plates 323 and the debris to move upward. When the dirt shielding frame 320 moves to the end of the inner tank frame 20, the lifting rod 324 is rotated and the lifting rod 324 is pulled upward. The filter 320 is then moved back into the hopper 320 and out of the hopper 320. The filter 320 is moved back into the hopper 320 and out of the hopper 320. The filter 320 is moved back into the hopper 320 and out of the hopper 320. The filter 320 is moved back into the hopper 320 and out of the hopper 320.

[0049] Furthermore, the terms "first," "second," "number one," and "number two" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature designated as "first," "second," "number one," or "number two" may explicitly or implicitly include at least one such feature. In the description of the present invention, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.
