Specific embodiment
In order to keep the purpose of this utility model, technical scheme and beneficial effects clearer, below in conjunction with attached drawing, to this
The preferred embodiment of utility model is described in detail, to facilitate the technical staff to understand.
As shown in Figs. 1-2, the anti-inverted ventilation safety device of a kind of Mine Ventilator, including shell 1, moving vane 5, protection
Net 3, contact sensor 6, combined aural and visual alarm 7, fixed pin 2, the shell 1 by fixed pin 2 be fixedly mounted on blower 10 into
At air port, 1 outer end of shell is equipped with protective net 3, and moving vane 5 is mounted on 3 inner face of protective net, protective net 3 by shaft 4
For fixing moving vane 5, while external sundries can be stopped and enter blower 10, and can avoid manpower in 10 operational process of blower and miss
Protrude into blower 10, can not only effective protection blower 10, and existing security risk when operation can also be eliminated.Moving vane 5 is adopted
It is made of light-weight metal or plastics, 4 natural rotation of shaft can be surrounded on protective net 3, and 5 size of moving vane is greater than protective net
3 sieve pore, 9 size.When blower 10 run when, suction is in the open position moving vane 5, it is distinguished and admirable can be normal through when blower 10
When out of service, moving vane 5 is closed naturally by gravity, is completely covered by protective net 3, and prevention is reversely distinguished and admirable to be passed through, effectively
It solves the problems, such as the inverted air current occurred when the 10 non-concurrent operation of parallel connection of the shutdown of blower 10 and more Fans, guarantees mine ventilation system
System operational effect.The contact sensor 6 for 5 position of sensed activity blade, the combined aural and visual alarm are provided on protective net 3
7 are mounted on shell, and contact sensor 6 is electrically connected with combined aural and visual alarm 7, and contact sensor 6 is with combined aural and visual alarm 7 for monitoring
The working condition of moving vane 5 and protective net 3, when blower 10 is run, moving vane 5 is in by the generation suction of blower 10 and opens
Open state, it is distinguished and admirable can be normal through contact sensor 6 is not sensed by moving vane 5, issues signal, acousto-optic to combined aural and visual alarm 7
Alarm 7 issues work prompt；When blower 10 is out of service, moving vane 5 is closed naturally by gravity, is completely covered by protection
On the sieve pore 9 of net 3, prevention is reversely distinguished and admirable to be passed through, and after moving vane 5 is contacted with protective net 3, contact sensor 6 senses activity
Blade 5 issues signal to combined aural and visual alarm 7, and combined aural and visual alarm 7 is closed.When 7 operation irregularity of combined aural and visual alarm, then illustrate movable leaf
There are failures with protective net 3 for piece 5.The utility model is integrally directly mounted at 10 air inlet position of blower, and air inlet is wrapped completely
It wraps up in, realizes protection comprehensively, no dead angle eliminates existing security risk, the utility model when blower 10 is run and uses sound-light alarm
The working condition of 6 real time monitoring activity blade 5 of device 7 and contact sensor can be known and notify at the first time if operation irregularity
Related personnel repairs, and guarantee will not influence underground ventilating effect；And the utility model structure is simple, easy for installation, operation
Reliably, practical, it can be widely used in the ventilation of the mine down-hole of the industries such as black, coloured, chemical industry.
The anti-inverted ventilation safety device of Mine Ventilator is integrally directly mounted at 10 air inlet position of blower, and by air inlet
It is fully wrapped around, realize protection comprehensively, existing security risk when the operation of blower 10 and maintenance is eliminated at no dead angle.
