AI Technical Summary

Technical Problem

Existing storm drains are unable to effectively filter pollutants during the drainage process, causing pollutants to directly enter water bodies and resulting in environmental pollution.

Method used

A perforated hanging basket and filter layer, including filter membrane, filter screen, filter bag or filter brick, are installed in the rainwater inlet. Adsorbent materials such as graded sand and gravel are used for filtration. Combined with the overflow outlet design, this ensures smooth drainage and filtration effect.

Benefits of technology

It achieves effective filtration of rainwater during the drainage process, reduces pollutants entering water bodies, and adapts to the drainage needs of different regions.

Description

Technical Field

[0001] This utility model relates to the field of municipal drainage, specifically to a sewage interception and purification rainwater inlet. Background Technology

[0002] As a crucial component of urban drainage systems, storm drains primarily function to collect surface runoff from streets and guide it into underground drainage pipes. However, with rapid urbanization and the increase in paved areas, more stormwater runoff and associated pollutants, such as road deposits, oil stains, and garbage, are generated. If these pollutants are left untreated and directly enter water bodies, they will cause serious negative environmental impacts. Therefore, ensuring that storm drains can efficiently discharge stormwater while simultaneously filtering it effectively has become a pressing technical challenge. Utility Model Content

[0003] To address the above problems, this utility model proposes the following technical solution:

[0004] A sewage interception and purification rainwater inlet includes a well body and a cover plate. The cover plate is installed on the well body, and the inside of the well body is a sewage interception chamber. A hollow hanging basket is installed above the sewage interception chamber. A drain outlet is also provided on the well body.

[0005] Preferably, the cover plate is a rain grate.

[0006] Preferably, a filter layer is also installed on the hollow hanging basket.

[0007] Preferably, the filter layer is a filter membrane, filter screen, filter bag, or filter brick.

[0008] Preferably, the filter bag's filler material is an adsorbent material, which includes graded sand and gravel.

[0009] Beneficial effects:

[0010] This invention achieves effective filtration of rainwater while ensuring normal drainage by installing a hanging basket and an overflow outlet within the intercepting chamber. In a further embodiment, a filter layer can be installed in the hanging basket as needed, coordinating the filtration effect with unobstructed drainage to adapt to the actual drainage needs of different regions.

[0014] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0015] A rainwater interception and purification inlet includes a well body 5 and a cover plate 1. The cover plate 1 is a rainwater grate and is installed on the well body 5. The inside of the well body is a sewage interception chamber 6. A hollow hanging basket 2 is installed above the sewage interception chamber 6 for filtering the collected rainwater. The well body 5 is also provided with a drain outlet 7 for discharging the collected rainwater.

[0016] In a further embodiment, a filter layer 3 is also installed on the hollow hanging basket 2 for further filtration of rainwater. The filter layer 3 is specifically a filter membrane, filter screen, filter bag, or filter brick. The filler of the filter bag or filter brick is an adsorbent material, including graded sand and gravel. An overflow port 4 is provided at the upper part of the hollow hanging basket 2 to allow rainwater that cannot be filtered in time to flow into the bottom of the intercepting chamber 6 when the rainfall is too heavy. In the case of excessive rainfall, priority is given to drainage to prevent rainwater from overflowing from the cover plate 1.

[0017] When it rains, rainwater enters the perforated hanging basket 2 above the intercepting chamber 6 from the cover plate 1, and after being filtered by the filter layer 3, it enters the lower part of the intercepting chamber 6 and is then discharged from the drain outlet 7. When the rainfall is heavy, the rainwater in the perforated hanging basket 2 cannot be filtered in time. After the water level rises to the overflow outlet 4, it overflows from the overflow outlet 4 and enters the lower part of the intercepting chamber 6, thus prioritizing smooth drainage at this time.

[0018] 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 principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
