Technical field
It the utility model is related to mire ventilation safety field, and in particular to a kind of mine main ventilator Antiexplosive manhole cover.
Background technology
Currently, as the continuous development of China's economy, the demand of coal resources constantly increase, the dynamics of coal mining is also got over
Come bigger, but the danger such as gas explosion, dust, asphyxia, poisoning may be faced in progress of coal mining, and accident occurs
When, if cannot divulge information in time, irremediable consequence can be caused.Mine ventilation is the most basic ring of shaft production link,
It occupies very important status all the time in mine construction and production period.Antiexplosive manhole cover is the important of guarantee mining ventilation and safety
One of equipment, it, which is responsible for, ensures underground gravity-flow ventilation and delivered downhole fresh air, and realizes the important task of underground inverted ventilation.But
The Antiexplosive manhole cover of onsite application due to itself there are the defects of, in practical applications there are problems, do not adapt to colliery
Safety code requirement.
When mine safety accidents occur, strength is huge as caused by explosion, and situation is complicated, so Antiexplosive manhole cover
There should be certain adaptive and respond.But there are major defect and security risk, outstanding behaviours for existing Antiexplosive manhole cover
For：Do not buffer and limiting device, when brisance is powerful, well lid may be blown up, and cause Antiexplosive manhole cover can not answer for a long time
Position；Without reliable guiding mechanism, well lid is during opening and closing, it may occur however that offset, deflection so that door body is difficult to standard
Really reset, cause it is poorly sealed between well lid and base, or even ventilation short circuit；And when wind turbine breaks down, well lid cannot be fast
Speed is opened, and realizes the gravity-flow ventilation of underground.So traditional Antiexplosive manhole cover produces mining ventilation and safety very severe influence.
The content of the invention
In view of the above shortcomings of the prior art, the purpose of this utility model is to provide a kind of explosion-proof well of mine main ventilator
Lid, solve the underground caused by Antiexplosive manhole cover deformation and ventilation blower failure cannot normally divulge information, quick inverted ventilation and gravity-flow ventilation etc.
Problem.
In order to solve the above technical problems, the technical solution of the utility model is：A kind of mine main ventilator Antiexplosive manhole cover, bag

The well lid of both sides is respectively provided with belt pulley, is attached by flute profile belt with motor, and the rotation of motor drives well lid around fixation
Hinged-support rotates, in addition, the surrounding in mounting base is equipped with buffering stand, and rubber bumper is housed on buffering stand.
Upper well lid and lower well lid afterbody and inside are respectively provided with water tank, pass through PVC feed pipes between inner water tank and outer water tank
Connection, the interior installation normally closed solenoid valve water valve of inner water tank, and water pump is installed in outer water tank.
Upper well lid and lower well lid are attached most importance to stacked, and lap is arc docking, is provided with rubber slab in cambered surface, docks
Place top is provided with bulb plunger stainless shot lock.
Compared with prior art, the beneficial effects of the utility model are：Antiexplosive manhole cover is designed as opposite opened, quick-fried when occurring
When fried, outer water tank can be relied on well lid is opened rapidly, main fan is exempted from damage.After explosion terminates, installed in installation
Motor on seat, which rotates, makes well lid reset rapidly, it is ensured that the normal ventilation of underground.Water tank also is provided with inside well lid, it is with two well lids
The bulb plunger stainless shot lock of joint coordinates, and makes close between well lid joint and mounting base and sponge rubber sealing strip
Connection, improves the sealing effect of well lid.Antiexplosive manhole cover design is reasonable, reliable operation, can realize well lid automatic open close, fast
Position is replied immediately, ensures the normal ventilation and gravity-flow ventilation of underground, improves the security of pit mining.

Embodiment
The utility model is described in detail below in conjunction with the accompanying drawings：With reference to Fig. 1 to Fig. 5, a kind of mine main ventilator is prevented
Quick-fried well lid, including mounting base 1, lower well lid 2, upper well lid 3, buffering stand 5, No. two motors 7, No.1 motor 11, switch boards 21, peace
Dress seat 1 is equipped with fixed-hinged support 9, is symmetrically distributed in the left and right sides of mounting base 1, is hinged by axis pin and well lid, and well lid is pair
Open type, including upper well lid 3 and lower well lid 2, can rotate rotating around fixed-hinged support 9, and the well lid of both sides is respectively provided with belt pulley, electricity
Machine is attached by flute profile belt 8 with motor, and the rotation of motor drives well lid to be rotated around fixed-hinged support 9, in addition, installing
The surrounding of seat is equipped with buffering stand 5, and coordinates on buffering stand 5 equipped with rubber bumper 4 and No.1 close to switch 6, three
It is to realize the buffering to well lid, position-limiting action, improves the reliability of well lid.
Upper well lid 3 and lower 2 afterbody of well lid and inside are respectively provided with water tank, pass through PVC between inner water tank 15 and outer water tank 10
Feed pipe 13 connects, and inner water tank 15 installs normally closed solenoid valve water valve 14, and water pump 12 is installed in outer tank 10.
Upper well lid 3 and lower well lid 2 are eclipsed form, and lap docks for arc, and rubber slab 18 is provided with cambered surface,
Joint top is provided with bulb plunger stainless shot lock 16.
The operation principle of the utility model is as follows：During normal ventilation, Explosion-proof cap is closed, and is filled in inner water tank 15
Water, by the dead weight of inner water tank 15 and the cooperation of bulb plunger stainless shot lock 16 and lock tongue slot 17, makes lower well lid 2 and upper well lid
Lap arc rubber slab 18 closely connects between 3, and upper well lid 3 and lower well lid 2 are closely matched somebody with somebody with sponge rubber sealing strip
Close, ensure that underground is normally divulged information.Signal is detected when No. two on underground generation explosion time, mounting base 1 approach switch 20, will be believed
Number programmable controller is transmitted to, programmable controller sends signal, normally closed electromagnetism to normally closed solenoid valve water valve 14
Valve water valve 14 is opened, and inner water tank 15 flows rapidly into outer water tank 10, Explosion-proof cap is opened rapidly by the dead weight of outer water tank 10, is avoided
Because the shock wave that explosion produces destroys chief ventilators.After explosion occurs, the No.1 positioned at buffering stand 5 is supervised close to switch 6
Measure well lid and be in opening, signal is transmitted to programmable controller, programmable controller, which sends signal, to be made
No. two motors 7 rotate, and begin to shut off lower well lid 2, and after certain time, programmable controller, which sends signal, makes No.1 electric
Machine 11 rotates, and begins to shut off well lid 3, when the No.1 on buffering stand 5 detects that well lid is begun to shut off close to switch 6,
Programmable controller closes normally closed solenoid valve water valve 14, and water pump 12 is started to work, and the water of outer water tank 10 is transferred to interior
Water tank 15, completes the rapid reset of Antiexplosive manhole cover.
When wind turbine breaks down, the sensor on wind turbine sends programmable controller signal, while can
Program controller opens normally closed solenoid valve water valve 14, the water in inner water tank 15 is flowed rapidly into outer water tank 10, by outer
The dead weight of water tank 10 makes Antiexplosive manhole cover open rapidly, it is ensured that underground gravity-flow ventilation, ensures the safety of coal mining.
Certainly, the above description is not intended to limit the present invention, and the utility model is also not limited to the example above,
The variations, modifications, additions and substitutions that the technology of the art is done in the essential scope of the utility model, fall within this reality
With new protection domain.
