Description

Flooding-proof door

Technical Field

The invention relates to the technical field of flood control safety facilities, in particular to a flood control door.

Background

This section provides background information related to the present disclosure only and is not necessarily prior art.

With the rapid development of urban rail transit, subways have gradually become the first choice of transportation for citizens to go out. The subway is usually arranged below the ground, is a relatively closed space, has the characteristics of concealment, blockade, high density of personnel and equipment and the like, and is difficult to evacuate and rescue. The way of communicating the subway with the outside is mainly through air shafts, entrances and exits, line openings and the like. Therefore, when flood disasters happen to cities, flood can preferentially enter the interior of the subway and rapidly spread to the whole communication area of the subway. In recent years, inland water disaster caused by urban rainstorm frequently occurs, and the inland water disaster becomes a new form of urban underground rail transit disaster.

The entrance and exit of the subway station are the key points and the difficulty of flood prevention of the station. The traditional flooding prevention measures of the station entrance and exit at present are to use sand bags, flooding prevention baffles and the like for plugging, and have the following obvious defects:

(1) Needs a large amount of manpower and material resources and has slow reaction speed. The traditional method is that a water baffle or a sand bag which is prepared in advance is manually carried and plugged at an entrance, and the flood prevention measure firstly needs to prepare a large amount of materials in advance, occupies a special storage space, needs to be carried manually, has large workload, consumes manpower and time, has low reaction speed and untimely plugging, and is very easy to cause flood backflow accidents.

(2) The emergency handling capacity of key posts and field operators on duty is insufficient, and flood disasters are easy to confuse, thus wasting rescue time and even bringing about larger accidents.

(3) Poor sealing performance, poor reliability and poor plugging effect. The traditional flooding prevention measures rely on the accumulation of baffles or sand bags, the sealing performance is poor, and the conditions of water seepage and water leakage are easy to occur along with the accumulation of time; and secondly, the reliability is poor, the hydrostatic pressure is increased along with the increase of the depth of accumulated water, the dynamic water pressure is also accompanied according to the difference of flow rate, and the traditional baffle or sand bag is very easy to break or collapse.

When the flood-proof door body 100 needs to be lifted, the driving member 410 acts to drive the plurality of lifting assemblies 430 to be lifted through the driving member, so that the lifting of the flood-proof door body 100 is realized. Because the number of the lifting assemblies 430 connected with the flooding-proof door body 100 is still kept to be a plurality, the lifting stability of the flooding-proof door body 100 is ensured, meanwhile, the lifting assemblies 430 connected with the flooding-proof door body 100 are driven to lift through the same driving piece 410, and compared with the mode that one lifting assembly 430 is provided with one driving piece 410, the occupied space of the device can be reduced, and meanwhile, the investment cost can be reduced.
