Description
Technical field
The utility model relates to a kind of firedamp sensor protective device of Coal Mine work hat, particularly mining illuminating lamp.
Background technology
In the situation that the coal production rapid growth also brings the particularly serious Frequent Accidents in colliery.The Tenth Five-Year Plan period, 1398 of dead 3-9 people's major accidents occur once in national colliery altogether, occur every year on average 280, account for national all kinds of major accident and play several 11%; 214 of dead 10-29 people's serious accidents occuring once, occur every year on average 43, accounts for national all kinds of serious accident and play several 36%; 42 of the above special major accidents of dead 30 people occuring once, occur every year on average 8, accounts for all kinds of special major accidents in the whole nation and play several 58%.Mainly mining in the coal enterprise of China and the world, to compare gap large for the national security production level.The Tenth Five-Year Plan period, 1,000,000 tons, colliery mortality ratio by 5.07 of calendar year 2001 drop to 2005 2.81, descended 45%, to compare gap also very large in country but mine with the advanced person.2005, coal in China output accounted for 37% of the whole world, and it is nearly 80% that death tolls accounts for, and 1,000,000 tons, colliery mortality ratio is about 80 times of the U.S., 17 times of South Africa, 10 times of Poland, Russia and India 7 times.Severe safety production situation not only serious threat people's life security and health, also has influence on social harmony and international image.The China's coal-mine overwhelming majority is Jing Gongkuangjing, complex geologic conditions, and Disasters Type is many, distributes wide, and mining conditions is the poorest in the world each main producing coal country, disaster is the most serious.In State owned coal mine, complicated geological or extremely complicated colliery account for 36%, and tectonic structure simple colliery accounts for 23%.According to investigations, 456 meters of the average mining depths in big-and-middle-sized colliery are adopted dark mine output greater than 600 meters and are accounted for 28.5%.Little colliery is on average adopted dark 196 meters, adopts the dark mine output that surpasses 300 meters and accounts for 14.5%.Gas Disaster.In State owned coal mine, gassy mine accounts for 21.0%; Coal and gas outburst mine accounts for 21.3%; Low gaseous mine accounts for 57.7%.In local state-owned coal mines and Township Coal Mine, high gas and coal and gas outburst mine account for 15%.Along with the increase of mining depth, the increase of gas emission, the ratio of high gas and coal and gas outburst mine also can increase.The China's coal-mine hydrogeological condition is comparatively complicated.In State owned coal mine, hydrogeological condition belongs to complicated or extremely complicated mine and accounts for 27%, belongs to simple mine and accounts for 34%.In local state-owned coal mines and Township Coal Mine, hydrogeological condition belongs to complicated or extremely complicated mine and accounts for 8.5%.China's coal-mine water damage ubiquity, big-and-middle-sized colliery have more than 500 workplace threatened by water damage.In nearly 20,000 little collieries, place, mine 900 many places of gushing water danger are arranged, account for 4.6% of sum.
To mine safety in Gas Disaster, normally " first take out afterwards adopt, monitoring, with the wind fixed output quota " the control of coalmine gas working policy, but due to the heavy output of many enterprises existence, the thought of light safety, and the miner is too low to pacifying individual right to know, detected gas is exceeded standard can not get paying attention to, the miner can not make quick action to the very first time gas situation of exceeding standard, and makes can not implementing from basic unit of can not managing safely, causes the coal-mine gas disaster constantly to occur.
Can not in time support the first-hand resource of controlling in the ore deposit after the generation mine disaster is also to cause an important component part of coal mining accident extension.After mine disaster occurs, Communication Block under the ore deposit, the personnel's distribution situation under the ore deposit can not clearly support control, makes decision-making cannot take out best scheme.
Summary of the invention
The purpose of this utility model is to provide a kind of miner can make to the very first time gas situation of exceeding standard the firedamp sensor protective device of touch-and-go mining illuminating lamp.
The purpose of this utility model is to realize like this; the firedamp sensor protective device of mining illuminating lamp; it is characterized in that: the gas detecting unit is arranged in mine lamp; the gas detecting unit is fixed in the housing of mine lamp; the gas detecting unit detects methane gas by firedamp sensor; firedamp sensor and housing in the gas detecting unit have respiration channel, and respiration channel has the respiratory protection film outward, and the gas detecting unit is electrically connected to charging circuit.
Described housing pros are lighting lamp reflective cover, lighting lamp reflective cover has been embedded in the LED illuminating lamp, and the LED illuminating lamp is made of LED more than two groups at least, is controlled at economize on electricity or non-electricity-saving state by button, economize on electricity is part LED work, and non-economize on electricity is all LED lamp work.
Described gas detecting unit comprises single-chip microcomputer, single-chip microcomputer is electrically connected to firedamp sensor by filtering and amplifying circuit, the firedamp sensor head is over against the housing respiration channel, the firedamp sensor signal is input to the single-chip microcomputer input end with A/D converter after by filtering and amplifying circuit, the gas detecting unit is electrically connected to rechargeable battery by electric power management circuit, charging circuit is electrically connected to electric power management circuit, rechargeable battery is managed by electric power management circuit, supply with single-chip microcomputer, filtering and amplifying circuit power supply, provide electric current to illumination LED simultaneously.
