Description
Technical Field
The invention relates to the technical field of urban waterlogging prevention, in particular to an energy-consumption-free automatic water retaining device for waterlogging prevention of an underground garage and a street-approaching storefront.
Background
Along with the rapid development of urbanization in China, urban ground space is increasingly in short supply, various urban underground spaces are rapidly developing at a remarkable speed, and the number of underground facilities such as large underground shopping malls, underground garages, river-crossing tunnels, subways, civil defense facilities and the like is increasing day by day. In China, "heavily overgrown and lightly underground" is a common problem in accelerating the process of urbanization, is hidden under beautiful tall buildings and is a fragile drainage system in cities. Under the great trend of global climate change, extreme rainstorm events and waterlogging disasters frequently occur in recent years, so that serious life and property losses are brought to people, and urban safe operation is seriously influenced. When each big city suffers from serious waterlogging, the condition that the underground space is subjected to water inflow and disasters also happens occasionally. In 2005, "Maisha" was flooded in 78 underground spaces in Shanghai city during typhoon, in 2008, in 7/4 th day, water was supplied to Beijing subway line 5 Chong station due to rainstorm, and partial line was shut down, and in 2010, in 16 th day, in 5/16 th day, water was supplied to tunnel near Guangzhou subway line 2 ground station due to continuous rainstorm, and the whole line was shut down for 6 h. The inland inundation disasters cause great loss to various aspects such as urban traffic and communication which are closely related to the life of people.
Compared with the ground building, the underground space has relatively low probability of flooding failure, but once the underground space is damaged by a disaster, the underground space is difficult to recover after the disaster. At present, China is in the initial stage of underground space development and utilization, a device capable of effectively preventing underground spaces such as garages and street-approaching storefronts from being damaged by waterlogging is designed in a targeted mode, the defense capability of the underground spaces for the waterlogging can be greatly improved, the damage of the waterlogging is relieved and controlled, and the device has very important significance for guaranteeing social, economic and safety and sustainable development.
At present, the urban waterlogging prevention of China is mainly realized by macroscopical regulation and control, sponge city construction, analysis and early warning, and waterlogging prevention pump stations and water storage tanks. The flood disaster has no effective prevention and treatment measures for the damage of individuals in cities, such as underground garages and street-approaching shops, the underground garages and the street-approaching shops are generally square structures with front side doors, when the flood disaster occurs, water in sewers in the underground garages and the street-approaching shops overflows and flows into the underground garages and the ground on the inner sides of the street-approaching shops (as shown in an attached drawing 1), namely, the existing urban flood prevention can not effectively protect individual buildings in the cities, and the flood disaster is difficult to accurately prevent and treat due to the uncertainty of rainfall and climate.
In view of the above disadvantages, there is a need to design and develop an energy-consumption-free automatic water retaining device for preventing waterlogging in an underground garage and a storefront, which can effectively protect the underground garage and the storefront from being damaged by waterlogging.

In order to realize the purpose of the invention, the invention adopts the technical scheme that:
the invention discloses an energy-consumption-free automatic water retaining device for preventing waterlogging of an underground garage and a storefront, which comprises bayonets, water retaining plates and floating blocks, wherein the bayonets, the water retaining plates and the floating blocks are arranged below wall bodies on two sides; the water baffle is arranged between the sewer and the ground at the inner side, and two ends of the water baffle are inserted into the bayonet and are matched with the bayonet to slide along the vertical direction; the floating block is arranged in the sewer and connected with the outer wall of the water baffle to form an L-shaped structure in combination with the water baffle, a first magnet is arranged at the bottom of the floating block, and a second magnet with the magnetic pole opposite to that of the first magnet is arranged at the bottom of the sewer.
The water baffle and the floating block are both of hollow square structures.
The water baffle and the floating block are made of engineering plastics.
The top of the sewer is provided with a sewer cover plate, and the water baffle is arranged between the sewer cover plate and the inner side ground.
A gap is arranged between the inner wall of the water baffle and the ground at the inner side.
And a gap is arranged between the outer wall of the water baffle and the side wall of the sewer cover plate.
The bayonet is a square groove structure with the bottom and the front opening formed by an upper side abutting plate, an inner side abutting plate and a side plate, and the side plate is provided with a plurality of bolt holes which are matched with bolts to fix the side plate below the inner side of the wall body.
