Abstract
The utility model relates to a cap type methane measuring device which is firmer, safer, more convenient and faster. The cap type methane measuring device consists of a shell and a measuring device body arranged in the shell, wherein the shell consists of a front shell and a rear cover; and the rear cover is designed to be a cap type, and is fixedly connected with the front shell by a fastening piece. The cap type methane measuring device is firmer and lighter, so the use safety and convenience can be greatly improved.
Description
Technical field
The utility model relates to a kind of apparatus for determination of gas, particularly a kind of hat type methane analyzer.
Background technology
Gas is the accompaniment of coal mining, and gas explosion is one of the great disaster in colliery, serious threat, and Safety of Coal Mine Production also is the emphasis of respectively mining state's research and prevent in the world today.At present the methane analyzer that uses of colliery mostly is portable, and the circuit of known portable methane analyzer is by sensing element at present, amplifying circuit, and A/D change-over circuit, single-chip microcomputer, signal output apparatus, sound light alarming circuit, display circuit is formed; Can carry out continuous monitoring to methane concentration.Its shortcoming is sensitivity and poor stability, and the working time is short, is not suitable for mining work under mine.
In the prior art, have methane analyzer is inhaled on safety helmet by the form of magnet, because magnet weight is very big, drop easily, security can not be guaranteed.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of more firm, safer, hat type methane analyzer more easily at above drawback.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of hat type methane analyzer, by housing with place the analyzer body of housing to form, wherein, described housing is made up of procapsid and bonnet, described bonnet is designed to hat type.
Above-mentioned a kind of hat type methane analyzer, wherein, described procapsid is fixed in the rear of hat type bonnet by fastener.
Beneficial effect of the present invention is: bonnet is designed to hat type, fixedlys connected with procapsid by fastener, and is more firm, lighter, increases security and the convenience of using greatly.
Description of drawings
Fig. 1 is side view of the present utility model
Fig. 2 is front view of the present utility model
Embodiment
The invention will be further described below in conjunction with accompanying drawing.
A kind of hat type methane analyzer as shown in the figure, by housing with place the analyzer body 1 of housing to form, wherein, housing is made up of procapsid 2 and bonnet 3, bonnet 3 is designed to the shape of safety helmet, procapsid 2 is fixed in the rear of hat type bonnet 3 by fastener, and simultaneously, front end 4 places of hat type bonnet 3 arrange a safety miner's lamp.
Methane analyzer body 1 comprises sensing element, amplifying circuit, A/D change-over circuit, microprocessor, warning circuit, real circuit and the power circuit that monitoring methane is used, methane analyzer body 1 is placed in the housing, the start back is monitored methane concentration value in the air in real time, the concentration range of monitoring is 0-10%, when methane concentration surpasses the alarm set point that arranges, warning circuit is reported to the police, and display shows current methane concentration value.
In sum, the utility model product before is more firm, lighter, increases security and the convenience of using greatly, has farthest guaranteed user of service's personal safety.
Here description of the present utility model and application is illustrative; be not to want with scope restriction of the present invention in the above-described embodiments; therefore, the present invention is not subjected to the restriction of present embodiment, and the technical scheme that any employing equivalence replacement obtains is all in the scope of protection of the invention.
Claims (2)
1. hat type methane analyzer, by housing with place the analyzer body of housing to form, it is characterized by, described housing is made up of procapsid and bonnet, described bonnet is designed to hat type.
2. a kind of hat type methane analyzer as claimed in claim 1 is characterized by, and described procapsid is fixed in the rear of hat type bonnet by fastener.
