Mobile jib (5) is connected composition extension apparatus with secondary bar (6) by rod member connecting bolt (7), and button touching head (3) is arranged In fixing device (1) and it is directed at the button of Portable Methane Detection Alarm, the end of secondary bar (6) is swivel bolt (4), rotation It is corresponding with the position that button touches head (3) to turn bolt (4).
Range limiter (8) is arranged on the bottom of extension apparatus, range limiter (8) to limit swivel bolt (4) with The distance between button touching head (3);
Button switch spring (9) is connected to mobile jib (5), secondary bar (6) bottom, and pressing button switch spring (9) makes rotation spiral shell Bolt (4) is contacted with button touching head (3), and button touching head (3) opens Portable Methane Detection Alarm.
Range limiter (8) is to limit button touching head (3) and swivel bolt (4);Mobile jib (5) and secondary bar (6) length Can be adjusted, adjustable range is 1m~3m.
Swivel bolt (4) is connected device (1) and mobile jib (5), realize being in 0 ° between fixing device (1) and mobile jib (5)~ 90 ° rotate and fixed, and button touching head (3) is directed at all the time Portable Methane Detection Alarm button.
To dead angle to be checked, pressing button switch spring (9) drives button touching head to extension apparatus (mobile jib (5), secondary bar (6)) (3) opening Portable Methane Detection Alarm carries out self-inspection.
Compared with prior art, the utility model has the advantages that.
1st, the utility model can have effectively achieved the accurate detection of the remote dead angle position gas concentration in tunnel.
2nd, the utility model has been effective to ensure that the inherently safe of gas testing staff.
