Description
Technical field
The utility model relates to civil air defense constructions and installations air inlet oral area technical fields more particularly to a kind of civil air defense constructions and installations to enter the wind oral area knot
Structure.
Background technique
Civil air defense constructions and installations is civil air defense projects, is also civil air defense works, is referred to ensure wartime personnel and goods and materials masking, the people
The wartime that air defense control, medical aid and the underground protective structure individually built and combined ground building are built can be used for preventing
Empty basement.
Diffuser casing is the important component of people's air defense oral area (outer), belongs to one of wave absorption facility.People's air defense diffuser casing is not envelope
The space closed is communicated with the outside world by suspension type explosion wave prevention active door, coarse filter etc., passes through the processing of emergency, shape in wartime
At a more closed space, ventilation is aerated by people's air defense different draft type of divulging information.
Ordinary circumstance air inlet needs to be arranged the functions rooms such as diffuser casing, dedusting gas-filtering room, Ventilator Room, airtight passage, works as punching
Wave is hit can temporarily play the role of buffering, but sometimes since diffuser casing can not be not enough arranged in the interior space.
Utility model content
The purpose of the invention of the present invention is to provide a kind of civil air defense constructions and installations to enter the wind oral structure, is mentioned using the utility model
The technical solution of confession solves the insufficient civil air defense constructions and installations of the interior space can not be the technical issues of entering the wind oral area setting diffuser casing.
In order to solve the above-mentioned technical problem, the utility model provides a kind of civil air defense constructions and installations air inlet oral structure, including people's air defense
The engineering interior space, the exterior space and the draft chamber formed between the interior space and the exterior space；In the ventilation
Interior is provided with ventilation equipment, and the outlet of the ventilation equipment is connected to by ventilation duct with the interior space, and entrance passes through tool
There is the air inlet oral area of sealing plate valve to be connected to the exterior space；It is also set between the entrance and ventilation valve of the ventilation equipment
It is equipped with diffusion chamber.
Preferably, the diffusion chamber is in body structure, has been respectively formed on ventilation hole in wherein two blocks of adjacent side plates；It is in office
Angle between two blocks of side plates of two pieces of meaning is each formed with reinforcing rib.
It preferably, further include bottom plate；The diffusion chamber is set to above the bottom plate by damping spring.
From the foregoing, it will be observed that it is available following using air inlet oral structure provided by the utility model the utility model has the advantages that by
It enters the wind oral area and diffusion chamber is set, while buffer function can be played, go back the inadequate problem of very good solution space.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be practical to this
Attached drawing needed in the description of new embodiment or the prior art is briefly described.It should be evident that being described below
In attached drawing be only that a part of the embodiment of the utility model is not paying wound for those of ordinary skill in the art
Under the premise of the property made is laborious, it is also possible to obtain other drawings based on these drawings.
Fig. 1 is that the utility model embodiment civil air defense constructions and installations enters the wind oral area structural schematic diagram.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe.Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without creative efforts
Every other embodiment obtained, fall within the protection scope of the utility model.
Need to be arranged the functions rooms such as diffuser casing, dedusting gas-filtering room, Ventilator Room, airtight passage in the air inlet of civil air defense constructions and installations,
When shock wave can temporarily play the role of buffering, but sometimes since diffuser casing can not be not enough arranged in the interior space.
For this purpose, referring to Figure 1, the present embodiment provides a kind of civil air defense constructions and installations to enter the wind oral structure, solves the interior space not
Enough, the technical issues of diffuser casing can not be set.
The civil air defense constructions and installations air inlet portion structure includes the civil air defense constructions and installations interior space 10, the exterior space 20 and empty indoors
Between the draft chamber 30 that is formed between 10 and the exterior space 20, ventilation equipment 31 are provided in draft chamber 30.
The outlet of ventilation equipment 31 is connected to by ventilation duct with the interior space 10, entrance by with sealing plate valve 32 into
Air port portion is connected to the exterior space 20.Diffusion chamber 40 is additionally provided between the entrance and ventilation valve of ventilation equipment 31.
Wherein diffusion chamber 40 is in body structure, has been respectively formed on ventilation hole in wherein two blocks of adjacent side plates；Any two
Angle between two blocks of side plates of block is each formed with reinforcing rib.
It further include bottom plate；Diffusion chamber 40 is set to above bottom plate by damping spring.
The present embodiment is by being arranged diffusion chamber 40 in air inlet oral area, when shock wave can temporarily play buffer function, also
Solve the problems, such as that space is inadequate.
Embodiments described above does not constitute the restriction to the technical solution protection scope.It is any in above-mentioned implementation
Made modifications, equivalent substitutions and improvements etc., should be included in the protection model of the technical solution within the spirit and principle of mode
Within enclosing.
