Automatic and manual flood control facility at ground entrance and exit of building

Abstract

The invention relates to an automatic and manual flood control facility at a ground entrance and exit of a building. The flood control facility comprises a flood control panel and a flood control binfor accommodating the flood control panel, wherein the flood control bin is arranged inside an accommodating groove formed in an entrance and exit floor of the building; a guiding structure and a wormjacking device are arranged between the flood control bin and the flood control panel; the worm jacking device is used for driving the flood control panel to life along the guiding structure so as toform a water retaining structure. The flood control facility has the beneficial effects as follows: the effective flood control height of the flood control facility and the movement speed of the flood control panel can be flexibly adjusted; the flood control panel is driven by the worm jacking device with a self-locking function, so that the flood control panel can be kept still under the conditions of an unexpected power failure and the like, and thus the flood control panel can be prevented from falling down accidentally; not only the worm jacking device can adopt electric driving, but alsolifting of the flood control panel can be manually driven in an emergency, so that the flood control facility can be adapted to various extreme weather conditions.

Description

technical field [0001] The invention relates to the field of building waterproofing, in particular to an automatic and manual flood prevention facility at the ground entrance and exit of a building. Background technique [0002] With the development of society, there are more and more urban underground projects, such as underground garages in residential areas, underground shopping markets, etc. These underground engineering facilities are easily damaged by natural disasters such as heavy rain, floods, and tsunamis. Because there is no good waterproof door at present, when a natural disaster occurs, a large amount of water will be injected into the underground engineering, so that the items in the underground engineering are often damaged, causing great harm and loss to people's lives and property. Contents of the invention [0003] The purpose of the present invention is to provide an automatic and manual flood control facility at the ground entrance and exit of a buildin...
