Urban rail station entrance and exit with anti-flooding mechanism and drainage method

Abstract

The invention discloses an urban rail station entrance and exit with a water flooding prevention mechanism and a drainage method, the urban rail station entrance and exit comprises a platform, a shell, a floating plate, a rack and a driving gear are matched with one another, a rotating shaft is driven to rotate by utilizing water rising to drive a water baffle to turn over, accumulated water flows into a drainage pipeline preset at the bottom through a groove, and the water flooding prevention mechanism is used for preventing water flooding. The left side of a first filter screen is jacked up through mutual cooperation of a driving bevel gear, a transmission bevel gear, a driven bevel gear, a second worm gear, a second worm, a second rotating rod and a first cam, so that garbage falling onto the first filter screen rolls down and is collected by a collecting tank; and meanwhile, the bottom of the first filter screen is knocked through mutual cooperation of a drainage pipe, a disc, a rectangular barrel, a fourth rotating rod, a first single-groove wheel, a second single-groove wheel, a belt, a third rotating rod, a second cam, a push plate, a spring and a steel ball, so that the garbage filtering efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of waterproofing, in particular to an entrance and exit of an urban rail station provided with a waterproofing mechanism and a drainage method. Background technique [0002] With the advancement of urbanization, the rapid growth of urban population and the current situation of rapid economic development have brought enormous pressure to urban transportation. The purpose is to relieve the increasingly serious traffic pressure. Three-dimensional traffic appears in the urban traffic system as a new form of traffic. Culverts, tunnels and interchanges are also the most basic forms of three-dimensional traffic. Underground passages have high space utilization and concealment. It has the characteristics of good safety and high traffic flow. However, due to the low terrain, improper handling of rain-proof measures at the entrance and exit can easily cause the surrounding water to overflow and cause traffic blockage....

AI Technical Summary

Problems solved by technology

[0002] With the advancement of urbanization, the urban population is growing rapidly, and the status quo of rapid economic development has brought great pressure to urban transportation. Technical policies and measures such as bus lines, rail transit, tunnel traffic, urban subways, and odd-even number restrictions have been introduced one after another. The purpose is to alleviate the increasingly serious traffic pressure. Three-dimensional traffic appears in the urban traffic system as a new form of traffic. Culverts, tunnels, and overpasses are also the most basic forms of three-dimensional traffic. Underground passages have high space utilization and concealment. It has the characteristics of good safety and good traffic flow, but due to the low terrain, improper handling of rain-proof measures at the entrance and exit can easily cause the surrounding water to backfill and cause traffic blockage

[0003] At the entrances and exits of existing urban rail stations, the amount of rainwater increases sharply during heavy rains, and it is impossible to automatically prevent flooding, so that it is easy for rainwater to flow into the underground passages of the stations, which is dangerous to a certain extent, and the accumulation of rainwater is easy to make the station The garbage at the entrance and exit flows into the station. When the water recedes, it is not easy to clean up the garbage, and the accumulation of garbage is easy to breed bacteria and odors, which affects the experience of passengers entering and leaving the station.
