Description

Technical Field

[0001] The present invention relates to the technical field of flood warning, and specifically provides a leapfrog flood control and drainage device for urban underground spaces. Background Art

[0002] Floods are water flow phenomena in rivers, lakes, and seas where the water volume rapidly increases or the water level rises rapidly due to natural factors such as heavy rain, rapid melting of ice and snow, and storm surges. However, it is relatively difficult to monitor floods in urban underground spaces. Therefore, a flood spread monitoring and warning device for urban underground spaces is particularly important.

[0003] The Chinese invention patent with the publication number CN103836432A discloses a flood storage and rainwater reuse system in a sponge city, including a rainwater reuse system and a flood storage system. A comprehensive rainwater treatment system is designed to address the deficiencies of the prior art, which can both store floods and recycle rainwater. In the flood storage system, the system can be started in a timely manner according to the precipitation, and the flood discharge effect is obvious, eliminating the problems of waterlogging every time it rains and rapid alternation between drought and waterlogging. The rainwater reuse system is combined with the buildings in the sponge city. Rainwater collection devices are built on the buildings and used for various purposes after a simple purification process, such as flushing toilets, mopping the floor, greening, artificial fountains, and industrial water use.

[0004] The Chinese invention patent with the publication number CN113554214A discloses a method for setting up an emergency evacuation route for a city to cope with floods, including the following steps: dividing the urban area into grid units; obtaining flood evolution process data and saving the data corresponding to the grid units according to the position coordinates; obtaining the flood inundation data of the urban area at the current moment to obtain the passable road network at the current moment; setting the starting point and ending point of the evacuation route, and obtaining all passable road routes at the current moment; starting from the route with the shortest distance among all passable road routes at the current moment, determining whether the route can be used as an emergency evacuation route, and finding a route that will not be flooded during the evacuation as the emergency evacuation route.

[0005] However, the existing warning devices have the following defects:

[0006] 1. When floods occur in the city, the underground space is at a relatively low altitude. After the flood spreads, it is easy to soak and damage the facilities and vehicles in the underground space. The existing warning devices can play a warning role but cannot make a response while warning.

[0007] 2. The existing warning devices cannot perform rapid drainage and vehicle transfer operations to ensure the safety of underground space facilities and vehicles. Summary of the Invention
