Abstract
Description
Technical Field
[0001] The present application relates to the technical field of urban drainage, and in particular to a sewage and rainwater interception outlet. Background Art
[0002] A stormwater inlet refers to a facility that collects surface water in a piped drainage system. It is a structure that collects rainwater on a stormwater canal or combined canal and consists of an inlet grate, a well body, and branch pipes. It is the basic component unit of a stormwater system. Rainwater from roads, squares, lawns, and even the roofs of some buildings first flows into the stormwater inlet through the grate, and then flows into rivers or lakes through connecting pipes. The stormwater inlet is the entrance for rainwater to enter the city's underground. It is an important facility for collecting ground rainwater and directly sends rainwater from the sky to the city's river and lake systems. It is both a bottleneck for the collection of rainwater runoff in the urban drainage system and the primary channel for urban non-point source pollutants to enter the water environment. It can not only drain urban roads, but also replenish urban water bodies.
[0003] Existing urban stormwater inlets are relatively simple in structure, often employing simple direct discharge or incorporating primary filtration devices to intercept larger particles from entering the drainage network. However, these traditional sewage interception inlets have several drawbacks: first, their filtration effectiveness is limited, failing to effectively intercept fine suspended matter, oil, and some soluble pollutants, leading to deteriorating water quality and impacting downstream water quality; second, they are prone to clogging, especially during heavy rain events, when large amounts of untreated rainwater and impurities rapidly influx, easily causing clogged stormwater inlets, impacting drainage efficiency and exacerbating the risk of urban flooding. Utility Model Content
[0004] In order to solve the problems raised by the above background technology, the present application provides a sewage and rainwater interception outlet.
[0005] The sewage interception rainwater inlet provided in this application adopts the following technical solution:

[0007] A mounting groove is provided on the top side of the interior of the trash box, and a drainage port is provided on the lower surface of the trash box;
[0008] The support cover is located in the mounting groove and is used to cover the top of the dirt trap box. A plurality of rainwater inlets for drainage are formed at equal intervals on the upper surface of the support cover.
[0009] Both sides of the T-shaped filter box are located in the mounting groove, and the interior of the T-shaped filter box is symmetrically provided with a mounting frame, and three groups of slots are horizontally opened inside the mounting frame, and the interiors of the three groups of slots are all snap-connected with plug-ins, and the interiors of the three groups of plug-ins are respectively provided with a coarse grid layer, a fine filter layer and a biological adsorption layer from right to left. A limiting component for fixing the mounting frame is provided in the T-shaped filter box, and a plurality of drainage holes are evenly spaced on the left and right sides of the interior of the T-shaped filter box.
[0010] Preferably, the limiting assembly includes multiple limiting plates, and the multiple limiting plates are fixedly connected to the inner wall of the T-shaped filter box. The mounting frame contacts the side walls of two adjacent limiting plates. Bolts are symmetrically threaded on the side walls of the limiting plates, and multiple threaded holes for use with the bolts are opened on one side of the mounting frame.
