Steel tube end part opening is supportted, is equipped in supporting steel pipe and gas sensor assemblies, gas sensor assemblies and signal processing unit
Electrical connection.
As an improvement the gas sensor that the gas sensor assemblies include multiple and different types combines to be formed,
Each gas sensor passes through individual signal wire and is electrically connected with signal processing unit.
As an improvement the upper end of the shell is equipped with sliding slot, supporting steel pipe is slidably mounted in sliding slot.It does not use
When, supporting steel pipe can be stored to sliding slot so that the volume of this gas-detecting device is smaller, easily facilitates and carries.
As an improvement the end of the supporting steel pipe is equipped with the stop collar that diameter is greater than the sliding slot.
As an improvement being equipped with the alarm being electrically connected with signal processing unit on the shell.
As an improvement the alarm be voice guard and/or vibration one of alarm and/or stroboscopic lamp or
A variety of combinations.
As an improvement the position for corresponding to gas sensor assemblies on the supporting steel pipe is equipped with venthole.
After the invention adopts the above technical scheme, compared with prior art, have the advantage that
