Description

Technical Field

[0001] This utility model relates to the field of building technology, specifically to a building drainage device. Background Technology

[0002] Architecture is a general term for buildings and structures, which are artificial environments created by people to meet the needs of social life; it includes buildings for people to live in, such as residential buildings and dormitories, or buildings for people to carry out various public activities, such as educational buildings (schools, kindergartens, etc.), office buildings (office buildings of government agencies and enterprises, etc.), and commercial buildings (shops, shopping malls, etc.).

[0003] Currently, during the construction of these buildings, a drain outlet is typically installed inside to drain water from the building. However, with traditional drainage pipes, debris can easily enter the pipes, causing blockages, poor drainage, and water accumulation inside the building. Installing floor drains at the drain pipe inlet can prevent debris from entering the pipe, but floor drains can only filter and collect debris in a simple way. They are prone to clogging at the drain pipe inlet, making it difficult to improve drainage and water accumulation problems, and still requiring frequent manual cleaning of the filtered debris in the floor drain.

[0004] In the prior art, CN220928450U discloses a building drainage pipe, including a pipe body. One end of the pipe body is connected to a sleeve, and the outer wall of the other end is threaded to facilitate the splicing of multiple pipe bodies. One pipe body is connected to an anti-clogging structure, which includes a filter plate embedded in the pipe body. The pipe body has a debris inlet at the point where it is embedded with the filter plate. A debris collection box is connected to the outer wall of the pipe body at the debris inlet. A branch pipe is connected to the bottom of the debris collection box, and the branch pipe is connected to the pipe body. A second filter plate is installed inside the debris collection box, and the debris collection box has a debris discharge port. A sealing plate is hinged at the debris discharge port. The anti-clogging structure can block and collect debris mixed in with rainwater, but it is difficult to solve the problem of blockage at the inlet of the drainage pipe caused by the concentrated collection of debris.

[0005] CN220888867U discloses an anti-clogging structure for building drainage pipes, including a filter assembly and a cleaning assembly. The filter assembly includes an inlet pipe, an anti-clogging barrel, a baffle, a mounting block, countersunk bolts, threaded holes, a filter plate, filter holes, an outlet pipe, and a bottom cover. The cleaning assembly includes a drive shaft, a rocker arm, an L-shaped plate, and a scraper. The cleaning assembly effectively removes impurities adhering to the lower surface of the anti-clogging barrel and the filter plate. However, the impurities scraped by the cleaning assembly are subject to gravity and simply fall to the bottom of the drainage pipe, failing to fundamentally improve the problem of debris entering the drainage pipe and causing blockage.
