Abstract
The utility model discloses a methane gas detecting alarm instrument. The methane gas detecting alarm instrument comprises a shell body, wherein a division plate is placed inside the shell body, an upper cavity is placed above the division plate, and a lower cavity is placed below the division plate. A methane sensor and a circuit board are placed in the upper cavity, and a battery compartment is arranged in the lower cavity. A digital display tube, an alarm, an alarm lamp and a membrane switch are positioned in a front panel of the shell body. The methane sensor, the digital display tube, the alarm, the alarm lamp and the membrane switch are respectively connected with the circuit board. The circuit board is connected with the battery compartment. The methane gas detecting alarm instrument has the advantages of being small in size, light in weight, easy to operate, convenient to maintain, and the like.
Description
Technical field
The utility model relates to the monitored gas environment device, is specifically related to a kind of methane gas detection alarm appearance.
Background technology
Methane gas detection alarm appearance is the gas controlling device that often use working sites such as colliery, metallurgy and environmental protection.Existing methane gas detection alarm appearance has that volume is big, weight is big, the shortcoming of poor sealing performance and Operation and Maintenance inconvenience.
Summary of the invention
To the defective or the deficiency of prior art, the purpose of the utility model is to provide a kind of methane gas detection alarm appearance.
The methane gas detection alarm appearance that is provided comprises housing, in this housing dividing plate is installed, and this dividing plate top is epicoele; The lower partition position cavity of resorption; Methane transducer and circuit board are installed in the said epicoele, are provided with battery compartment in the said cavity of resorption, said housing front panel is provided with digital display tube, alarm, alarm lamp and facial mask switch; Said methane transducer, digital display tube, alarm, alarm lamp and facial mask switch are connected with circuit board respectively, and said circuit board is connected with battery compartment.
Said housing outer wall is provided with demarcates mouth.
The methane gas detection alarm appearance of the utility model has characteristics such as volume is little, in light weight, simple to operation, easy to maintenance.
Description of drawings
Fig. 1 is the housing front-panel structure synoptic diagram of the utility model methane gas detection alarm appearance;
Fig. 2 is the inner structure synoptic diagram of the utility model methane gas detection alarm appearance.
Below in conjunction with embodiment and accompanying drawing the utility model is done further explain.
Embodiment
With reference to figure 1 and Fig. 2; The methane gas detection alarm appearance of the utility model comprises housing 1, is provided with dividing plate 4 in the said housing 1, and these dividing plate 4 tops are epicoele; 4 times position cavity of resorptions of dividing plate; Methane transducer 2 and circuit board 3 are installed in the said epicoele, are provided with battery compartment 5 in the said cavity of resorption, said housing 1 front panel is provided with digital display tube 6, alarm 9, alarm lamp 8 and facial mask switch 7; Said circuit board 3 is connected with battery compartment 5, and said methane transducer 2, digital display tube 6, alarm 9, alarm lamp 8 are connected with circuit board 3 respectively with facial mask switch 7.Said housing 1 outer wall is provided with demarcates mouth 10.
When instrument places the environment that has methane gas; Methane gas gets into air chamber through the transom window of tool housing and bonnet; Methane transducer (carrier catalyst element) surface in the air chamber produces flameless burning; Its resistance increases, the Wheatstone bridge out of trim output voltage signal that carrier catalyst element and resistance are formed, and the size of voltage signal is directly proportional with methane concentration.Data processing unit on the circuit board demonstrates methane concentration by charactron after handling, and after the concentration of methane surpassed the alarm set point of setting, instrument sent the sound and light alarm signal.When instrument maintenance, instrument is demarcated through demarcating mouth.
Claims (2)
