Abstract
Description
Technical Field
[0001] This utility model relates to a sewage interception device, belonging to the field of municipal engineering equipment. Background Technology
[0002] On roads where sanitation management is not timely (such as elevated roads and underpasses), there are often road debris, such as mud / sand, flaky objects (such as leaves and paper scraps), and needle-like objects (small twigs). In windy weather, the debris will be blown away, affecting traffic safety; in rainy weather, road runoff will carry road debris and get stuck at the inlet of the storm drain, mainly flaky and needle-like objects, which seriously obstructs water flow and affects the drainage efficiency of the storm drain. Utility Model Content
[0003] This invention provides a sewage interception device that solves the problems disclosed in the background art.
[0004] According to one aspect of this disclosure, a sewage interception device is provided, including a tunnel-shaped first channel with its outlet facing a rainwater inlet. A grid distributed along the length direction is provided at the bottom of the first channel, with a space between the end of the grid and the outlet of the first channel. An interception net is attached to the end of the grid, and the interception net extends upward to the top of the first channel after extending along the length direction of the first channel. A gap is left between the extension of the interception net along the length direction of the first channel and the bottom of the first channel.
[0005] Furthermore, after extending along the length of the first channel for a period of time, the interception net first extends upward in an arc, and then extends vertically upward to the top of the first channel.
[0006] Furthermore, the vertically extending section of the interception net is located at the exit of the first channel.
[0007] Furthermore, the first channel is also equipped with barbs, which are distributed at an angle, with the barbs higher near the inlet and lower near the outlet.
[0008] Furthermore, along the import to export direction, the size of the barbs in the barbs increases.
[0009] Furthermore, the exit of the first passage is supported by a barrier that obstructs part of the exit space.
[0010] Furthermore, the first channel is a channel with a wide inlet and a narrow outlet.
[0011] Furthermore, the first channel is a channel formed by dividing the second channel into tunnel-shaped sections. The second channel is equipped with several partitions distributed along its length, which divide the second channel into multiple first channels.
[0012] The beneficial effects achieved by this utility model are as follows: the grid at the bottom of the first channel allows mud / sand to settle, and the intercepting net at the end of the grid can intercept sheet-like and needle-like objects. Since the intercepting net extends along the length of the first channel, the channel below the extended section can always be unobstructed. It can be arranged in the groove in front of the rainwater inlet on the side of the road curb, thereby filtering the runoff entering the rainwater inlet, ensuring the drainage efficiency of the rainwater inlet, filtering the slag that passes through the first channel, and promoting traffic safety.

Therefore, features defined with "first" or "second" may explicitly or implicitly include one or more features.
[0023] To address the issues of water blockage caused by rainwater inlets and debris blown away by wind, this disclosure proposes a sewage interception device, specifically a filter device located in a groove in front of the rainwater inlet on the road curb.
[0024] See Figure 1 , Figure 1 This is a schematic diagram of a sewage interception device provided in an embodiment of this application. The device includes at least a tunnel-shaped first channel 1, with the outlet of the first channel 1 facing the rainwater inlet. A grid 2 distributed along the length direction is embedded or fixed at the bottom of the first channel 1. A space is left between the end of the grid 2 and the outlet of the first channel 1. An interception net 3 is attached to the end of the grid 2. The interception net 3 extends along the length direction of the first channel 1 for a period of time and then extends upward to the top of the first channel 1. A gap is left between the extension section of the interception net 3 along the length direction of the first channel 1 and the bottom of the first channel 1.
[0025] It should be noted that the first channel 1 is essentially a passageway for water and air flow. The structure can be varied. For example, the figure shows an n-shaped cover, which is tunnel-shaped. To adapt to the installation position, its top surface can be set as an inclined top surface, such as the side closer to the road surface being lower and the other side being higher.
[0026] The first channel 1 can be set up once or multiple times, depending on the size of the rainwater inlet. When multiple channels are set up, the first channel 1 can be a channel divided by a tunnel-shaped second channel 6, that is, a large channel is divided into multiple small channels. Several partition plates 7 are fixed in the second channel 6 along the length direction, and the partition plates 7 divide the second channel 6 into multiple first channels 1.
[0027] See Figure 2 The structure of the second channel 6 is similar to that of the first channel 1, and it can also be an n-shaped cover. Two partition plates 7 are fixed inside the second channel 6, dividing the second channel 6 into three first channels 1. The partition plates 7 facilitate the orderly flow of water and air through the channel, and the partition plates 7 also serve as support components to reinforce the second channel 6. Similarly, to adapt to the installation position, the top surface of the second channel 6 can be set as an inclined top surface, such as the side closer to the road surface being lower and the other side being higher.
[0028] It should be noted that in order to achieve better filtration, the flow rate needs to be reduced. Therefore, in some embodiments, the first channel 1 is set as a channel with a wide inlet and a narrow outlet, thereby achieving a large inlet and a small outlet, and realizing flow rate control.
[0029] In other embodiments, a barrier 4 can be placed against the outlet of the first channel 1 to block part of the outlet space. This barrier 4 can not only support the device and prevent water flow and air flow from pushing the device, but also narrow the outlet by blocking the outlet, so as to realize the flow rate control by making the inlet large and the outlet small.
[0030] See Figure 2 and 3 Since the second channel 6 of the n-type is directly embedded in the groove of the road surface, the abutment 4 can be a wedge-shaped limiting frame. The wedge-shaped limiting frame is located on the rear side of the second channel 6, generally extending 4-8cm to ensure the exit. The wedge-shaped limiting frame abuts against the partition plate 7 and is also embedded in the groove of the road surface. The height of the wedge-shaped limiting frame is less than the height of the second channel 6. The exits of the three first channels 1 are partially blocked by the side of the wedge-shaped limiting frame, thus realizing three channels with large openings and small openings.
[0031] It should be noted that, apart from the extension section along the length of the first channel 1, the shape of the remaining parts of the interception net 3 can be set arbitrarily, such as an upward-sloping shape or an upward-curving shape. Figure 1 In this system, the interception net 3 is roughly arc-shaped. Specifically, after extending a section along the length of the first channel 1, the interception net 3 first extends upward in an arc, and then extends vertically upward to the top of the first channel. The interception net 3 mainly consists of a flat net, an arc-shaped net, and a vertical net. One end of the flat net overlaps the end of the grille 2 (i.e., the end near the outlet), and the other end of the flat net connects to the vertical net through the arc-shaped net. The top of the vertical net connects to the top of the first channel 1, and the sides of all the nets are connected to the sides of the first channel 1. When the interception net 3 intercepts sheet-like or needle-like objects, under the impact of the water flow, the sheet-like or needle-like objects can move upward along the arc-shaped net, preventing the lower section of the interception net 3 from being blocked by the sheet-like or needle-like objects, thus facilitating the normal passage of water.
[0032] In order to intercept as many sheet-like and needle-like objects as possible and delay the clearing of the passage, the vertical extension of the interception net is located at the exit of the first passage, that is, the vertical net is located at the exit of the first passage.
[0033] It should be noted that, in some embodiments, in order to enhance the interception effect, barbs 5 are installed in the first channel 1. The barbs 5 can extend into and be fixed from the inlet, such as by fixing to the partition plate 7. The barbs 5 are distributed at an angle, with the barbs closer to the inlet being higher and the barbs closer to the outlet being lower. Furthermore, the size of the protrusions in the barbs 5 increases along the direction from the inlet to the outlet. This distribution can prevent the protrusions at the front end from intercepting sheet-like objects that block the channel.
[0034] The operation of the above-mentioned device is as follows: A groove is pre-drilled in front of the storm drain on the curb, ensuring the groove depth is greater than the height of the grid 2. Next, the interceptor device is placed flat in the groove, and the wedge-shaped limiting frame is fitted into the outlet end. If necessary, additional side fittings are added. When water or air flows through the interceptor device, the grid 2 causes mud / sand / lumps to settle, while the intercepting mesh 3 and spikes intercept sheet-like and needle-like objects. This not only filters the runoff entering the storm drain, ensuring drainage efficiency, but also filters the debris passing through the first channel, promoting traffic safety. This interceptor device requires regular or irregular maintenance, namely, cleaning the intercepted materials and sediment inside.
[0035] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
