Building drainage system adopting quick-drainage floor drain

Abstract

The invention is a divisional application of Chinese application 202010957890.0, and particularly relates to a building drainage system adopting a quick-drainage floor drain. The building drainage system comprises a drainage pipe network, wherein the drainage pipe network comprises an indoor drainage pipe and the quick-drainage floor drain; the quick-drainage floor drain comprises a floor drain outer cylinder and a floor drain inner core; the floor drain outer cylinder is vertically arranged in a ground building; the floor drain inner core comprises a sewer pipe, a floating sleeve and a rotating sleeve; the lower end of the sewer pipe extends into the floor drain outer cylinder, and a water passing port is formed in the sewer pipe; the floating sleeve is glidingly arranged on the sewer pipe in a sleeving manner and moves up and down along the sewer pipe; a plurality of spiral guide plates are uniformly distributed on the peripheral wall surface of the floating sleeve in the circumferential direction; the rotating sleeve is rotationally connected to the lower end of the sewer pipe; and a plurality of overflow structures are uniformly distributed on the peripheral wall surface of the rotating sleeve. Through cooperation of the spiral guide plates and the overflow structures, the water passing port is opened while the water outlet is increased when the drainage amount is large, and high-flow ground water can be drained quickly and timely.

Description

[0001] This application is a divisional application of the Chinese application with the application number 202010957890.0, the application date is September 12, 2020, and the invention title is "A Quick-Drain Floor Drain and Building Drainage System". technical field [0002] The invention relates to the technical field of building drainage, in particular to a building drainage system using a quick-discharge floor drain. Background technique [0003] The building drainage system is a system that can discharge rainwater, snow water, domestic sewage and industrial wastewater from the roof of the building to the drainage pipe network or treatment network outside the building in a timely and unimpeded manner, so as to provide people with a good life and production. , working and learning environment, so the quality of the building drainage system will directly affect the normal operation of life and production. [0004] Floor drains are the most commonly used drainage equipment ...
