Specific embodiment
To keep purpose and the technical solution of the embodiment of the present invention clearer, below in conjunction with the attached of the embodiment of the present invention
Figure, is clearly and completely described the technical solution of the embodiment of the present invention.Obviously, described embodiment is of the invention
A part of the embodiment, instead of all the embodiments.Based on described the embodiment of the present invention, those of ordinary skill in the art
Every other embodiment obtained, shall fall within the protection scope of the present invention under the premise of being not necessarily to creative work.
Those skilled in the art of the present technique are appreciated that unless otherwise defined, all terms used herein (including technology art
Language and scientific term) there is meaning identical with the general understanding of those of ordinary skill in fields of the present invention.Should also
Understand, those terms such as defined in the general dictionary, which should be understood that, to be had and the meaning in the context of the prior art
The consistent meaning of justice, and unless defined as here, it will not be explained in an idealized or overly formal meaning.
In order to realize to bilayer cells prefabricated cabin fireproof partition effect, while avoiding drawback of the existing technology.This Shen
Designing points please are: after lower layer's battery prefabricated cabin is installed in place, in the cabin of lower layer's battery prefabricated cabin top laying fire endurance
For the fire barrier of 3h.The fire barrier not load-bearing, the fixation of upper and lower battery prefabricated cabin is using the fixation between battery prefabricated cabin
Point 4 is attached fixation.It is immediate in the prior art, fireproof partition conventional design thinking between battery prefabricated cabin are as follows:
The energy storage cabin (battery prefabricated cabin) on upper layer is supported using separate structural, i.e., energy storage cabin in upper layer is supported using independent structure, upper
Fireproof partition is carried out using concrete floor between lower energy storage cabin, the fire resistance period of fireproof partition " is built according to GB50016-2014
Build code for fire protection design " it is 1h or more.It is the weight that carrying fireproof partition is carried out using lower layer's energy storage cabin, and fireproof partition
It is heavier.In operation first is that not being avoided that flame play, second is that construction is complicated, it is unable to rapid-maintenance.
The specific structure of technical scheme is a kind of prefabricated cabin structure of bilayer cells with fire prevention isolation features,
Including,
Two battery prefabricated cabins, two battery prefabricated cabins are laid in upper and lower, and respectively relatively independent；In two battery prefabricated cabins
Upper layer battery prefabricated cabin hanging type be installed on the top of lower layer's battery prefabricated cabin 2 so that upper layer battery prefabricated cabin 1 and lower layer's electricity
Fire prevention insulating space 3 is formed between pond prefabricated cabin 2, in order to which the insulating space 3 that guarantees to prevent fires has sufficient heat-insulating flame-retardant effect,
There is at least height space of 15cm, i.e. fire prevention isolation preferably between upper layer battery prefabricated cabin 1 and lower layer's battery prefabricated cabin 2
The height in space at least 15cm；It is connected between two battery prefabricated cabins using fixed point, specially the four of 2 top surface of lower layer's battery prefabricated cabin
It is equipped with mounting groove at a angle, is equipped with mounting post 7 at four angles of upper layer battery prefabricated cabin bottom surface, upper layer battery prefabricated cabin 1 passes through
Mounting post 7 (mounting post is also known as connector) is superimposed installation with the cooperation of mounting groove.
Fire barrier 5 is installed on the fire prevention insulating space 3, in order to realize the cooling of fire barrier 5, avoids upper layer electric
Heat is transmitted between pond prefabricated cabin 1 and lower layer's battery prefabricated cabin 2, is equipped with water cooling along fire barrier length direction in fire barrier 5
But pipeline 6, water composite cooling pipe road 6 are connected to external main pipeline 8；Water composite cooling pipe road is equipped with upward nozzle, covering after nozzle injection
Capping is the upper surface of fire barrier.Preferably at least two, water composite cooling pipe road, two water composite cooling pipe roads are laid side by side, with
5 upper surface of fire barrier is sprayed in realization comprehensively.
Flame up and down push up by play, the cabin that the area of the fire barrier is greater than lower layer's battery prefabricated cabin when catching fire in order to prevent
Area.Also, the width direction of fire barrier is greater than the width direction at least 10cm on lower layer's prefabricated cabin cabin top.
Meanwhile bottom and lower layer's prefabricated cabin cabin inner top are equipped with rock wool fire-retardant heat insulation in the battery prefabricated cabin cabin of upper layer
Layer, and thickness is not less than 10cm.Upper layer battery prefabricated cabin side wall and lower layer's battery prefabricated cabin side wall are equipped with rock wool fire-retardant heat insulation
Layer, and thickness is not less than 7.5cm.
In actual use, guaranteed first by water spray cooling outside fine mist fire-fighting cooling in energy storage storehouse and energy storage storehouse
Fire is controlled the safety for also ensuring that structure.The upper surface of the fire barrier is equipped with guiding gutter.
Followed by increase fireproof partition between two energy storage cabins, the fire endurance of fireproof partition need to reach 3h with
On.The fire barrier uses A class incombustible material.
Explosion belongs to extreme event, and control explosion is only main points, in energy storage storehouse emergency ventilation system and water mist system and
Shi Qidong controls combustible vapor and combustable gas concentration, reduces concentration to lower explosion limit 20% hereinafter, will not explode.If institute
There is control all to fail, fire is only controlled by hydrant system after explosion.
Compared with the prior art, the installation of energy storage cabin and later period maintenance replacement bring great convenience for the invention, tie
Structure requires low, low cost, and fire endurance is higher than architectural fire-protection methods code requirement.
For other field, such scheme has stronger implementation, may be implemented between distinct device main body
Fireproof requirement, avoids heat transfer, avoids fire spread.
The above is only embodiments of the present invention, and the description thereof is more specific and detailed, and but it cannot be understood as right
The limitation of the invention patent range.It should be pointed out that for those of ordinary skill in the art, not departing from the present invention
Under the premise of design, various modifications and improvements can be made, these are all belonged to the scope of protection of the present invention.
