Description
Technical field
The utility model is related to downhole safety protection, and in particular to a kind of vertical emergency management and rescue explosion vent apparatus.
Background technology
The existing highly gassy mine substantial amounts of China, the dangerous property coefficient of this kind of explosion of coal mines is high.Existing mire ventilation safety
Facility ventilating shaft explosion-proof door, Antiexplosive manhole cover is nearly all washed open by powerful air blast in all previous extra heavy big coal mining accident flies away from well
Mouthful, it is impossible to reset in time, ventilating system short-circuit failure, it is impossible to fresh distinguished and admirable to delivered downhole, it is impossible to discharge pernicious gas allows and robbed
Dangerous personnel lose rescue time of speedily carrying out rescue work, while also seriously having jeopardized the life security of underground coal mine staff, ultimately result in calamity
Feelings expand, wrecked number increase.Therefore to the research of mine explosion door, lid, improve the reliability to improving ventilating system and be
The anti-disaster ability of system is significant.And inquired about by the great mass of data for studying such new type explosion proof door transformation, existing skill
Art has one to be disadvantageous in that the requirement for not accounting for inverted ventilation jointly, easily occurs return air short circuit, and coal mine gas for many years is quick-fried
The significant damage that return air short circuit problem is brought is have also discovered in fried accident investigation, there are many miners is met on safe escape circuit
Difficult.Exactly a kind of mine emergency management and rescue explosion vent apparatus of the utility model, is washed from Antiexplosive manhole cover by powerful air blast
Its energy quick blocking return air well head, recovers underground ventilating system during well head, to be fresh distinguished and admirable needed for personnel in the pit provides escape,
Reduction explosion of coal mines is brought to greatest extent casualties and economic loss.
Utility model content
The utility model overcomes the deficiencies in the prior art and blows away return air well head peace when blast occurs for underground there is provided one kind
During the explosion proof door of dress, energy quick blocking return air well head recovers underground ventilating system, can in time coordinate when accident occurs and answer first aid
Help the vertical emergency management and rescue explosion vent apparatus of the implementation deployment of work.
A kind of vertical emergency management and rescue explosion vent apparatus of the present utility model, the device is at ventilating shaft mouthful, ventilating shaft mouthful upper end
Provided with explosion proof door, the explosion proof door is two folding semicircular structures, is distributed in fixed shaft device both sides, the fixing axle
Device includes gear motor rotating device, support and installs fixation.Requirement of such design in view of inverted ventilation, it is to avoid occur back
Wind short circuit, quick blocking return air well head recovers underground ventilating system.
A kind of vertical emergency management and rescue explosion vent apparatus of the present utility model, the explosion proof door is by semicircle carbon steel support and resistance to
High temperature flameproof fabric connection composition, the semicircle carbon steel support is uniformly arranged on support and installs fixed both sides.Explosion proof door is opened
When, it will not be lighted by the air blast of high temperature.Meanwhile, be uniformly distributed ensure that from air blast impact when stress it is equal
It is even.
On a kind of vertical emergency management and rescue explosion vent apparatus of the present utility model, the gear motor rotating device connection borehole wall
The temperature sensor of installation, the temperature sensor connects inducing receiver.Accident can react in time when occurring, quickly will be explosion-proof
Door is opened.
A kind of vertical emergency management and rescue explosion vent apparatus of the present utility model, the fire resistant cloth is ferroglass fiber
Cloth or basalt fibre flameproof fabric.Ensure that ferroglass fiber cloth or basalt fibre flameproof fabric will not be by high temperature when opening
Air blast is lighted.
A kind of vertical emergency management and rescue explosion vent apparatus of the present utility model, the semicircle carbon steel support is by place of magnetizing
Reason.Such design is more conducive to closure when explosion proof door is opened.
Provided with sealing hair on the neck at a kind of vertical emergency management and rescue explosion vent apparatus of the present utility model, the explosion proof door closure node
Wool top.More one layer of guarantee is provided for the seal of vertical emergency management and rescue explosion proof door.
Have the advantage that compared with prior art：The utility model compared with prior art, solves colliery and existed
In the case of generation gas explosion, explosion proof door is blown away by enormous impact force, it is impossible to close return air well head, causes Air escape branch phenomenon,
Jeopardize the phenomenon of personnel in the pit's life security；The emergency management and rescue explosion vent apparatus, it can quick blocking return air well head, recovery underground
Ventilating system, reduces casualties and economic loss that explosion of coal mines is brought to greatest extent.Using the normal airflow velocity in underground as 6
Exemplified by meter per second, the rescue function that this emergency management and rescue explosion vent apparatus often plays one minute just can provide 360 for underground escape personnel
The green life passage of rice, greatly enhances the effect of emergency management and rescue.
Brief description of the drawings
Fig. 1 is closure state schematic diagram of the present utility model；
Fig. 2 is opening schematic diagram of the present utility model；
The enlarged diagram that Fig. 3 is in Fig. 14；
The enlarged diagram that Fig. 4 is A in Fig. 2.
Embodiment
With reference to embodiment, the utility model will be further described, but the utility model is not limited only to these realities
Example, on the premise of without departing from the utility model objective, any improvement is all fallen within protection domain of the present utility model.
A kind of vertical emergency management and rescue explosion vent apparatus of the present utility model, explosion proof door 1 is that 10 width are by quantity
100mm, thickness be 15mm carbon steel bending machinings be it is semicircle, and processing of magnetizing magnetize carbon steel support 2 and ferroglass it is fine
The connection composition of cloth 3 is tieed up, the carbon steel support 2 that magnetizes is fixed at ventilating shaft mouthful by fixed shaft device 4, is provided with fixed shaft device 4
