AI Technical Summary

Technical Problem

In existing flood protection technologies for underground entrances and exits of buildings, the switching between drainage and water blocking relies on manual judgment, resulting in slow response speed. Furthermore, the reliability of automated devices is poor under extreme flood conditions, and they are prone to failure due to power outages.

Method used

An adaptive water deflector system is adopted, which automatically switches between drainage and water blocking by the weight and hydrodynamics of rainwater. The system includes components such as an adaptive water deflector, a rotating shaft, and a buffer tank to ensure automatic response in the early stages of rainfall and under extreme conditions.

Benefits of technology

It improves the response speed and reliability of drainage and water blocking, reduces backflow of water, and is suitable for the protection of entrances and exits of various underground buildings, especially effective under extreme disaster conditions.

Abstract

The present invention discloses an integrated drainage and water blocking system and a control method for building underground space entrances and exits, belonging to the technical field of urban building drainage, and is used to solve at least one of the problems in the prior art, such as untimely switching between drainage and water blocking, dependence on manual labor, dependence of automated devices on external power, and poor reliability under extreme working conditions. The integrated drainage and water blocking system of the present invention includes an adaptive water baffle and a rotating shaft; the adaptive water baffle includes an upper panel, a connecting panel, and a lower panel. The connecting panel and the lower panel are located below the upper panel. The upper panel, the connecting panel, and the lower panel are sequentially connected to form a water collecting trough. There is a water inlet gap between the upper panel and the lower panel. The lower panel is rotatably connected to the road through the rotating shaft. The present invention can be used for drainage and water blocking of building underground space entrances and exits.
