the winding mechanism (6) comprises a support plate (61), a rotating handle (62) and a winding drum (63), the support plate (61) is fixedly connected with the inner wall of the third accommodating groove (24), the support plate (61) is rotatably connected with the winding drum (63), the oxygen pipe (82) is wound on the outer wall of the winding drum (63), the winding drum (63) is of a hollow cylindrical structure with an opening at one end and a closed end, the closed end of the winding drum (63) is rotatably connected with the support plate (61), the winding drum (63) is communicated with the tail end of the oxygen pipe (82), the rotating handle (62) is arranged at the closed end of the winding drum (63), the rotating handle (62) is located on the back of the box body (2), and the rotating handle (62) is fixedly connected with the box body (2) through a limiting knob (621);
this gas monitoring alarm during operation, A: mine constructors can hang the gas monitoring alarm on the neck through a hanging rope (33), then adjust the length of the fixing belt (5) to enable the limiting head (53) to be connected with a proper limiting hole (52), and after the limiting head and the fixing hole are connected, the fixing head (51) is connected with the fixing seat (12), so that the alarm is firmly placed in front of the chest of the constructors, and the alarm is prevented from shaking randomly in the construction process;
b: when a constructor walks, the alarm can monitor the concentration of gas and coal gas at the position and carry out digital display, other constructors can clearly know the concentration of the gas and the coal gas through the monitoring alarm, and when the constructor wants to know the concentration, the constructor can extend fingers into the operating groove (11) and then push the shifting plate (41) to upwards turn over the shell (4) of the gas monitoring alarm, so that a display screen of the alarm can be upwards displayed, and the constructor can watch the gas and the coal gas; the monitored data can be transmitted to a monitoring room through a wireless transmitter (9), so that external personnel can know the concentration of gas and coal gas at each position under the well;
c: when the concentration exceeds the standard, the gas monitoring alarm gives an alarm, and then a constructor can open the cover plate (21), take out the oxygen mask (81) from the first accommodating groove (22), pull out the oxygen pipe (82) outwards, drive the winding drum (63) to rotate in the movement process of the oxygen pipe (82), so that the oxygen pipe (82) can continuously leave the winding drum (83), and the constructor can place the oxygen mask (81) at the mouth and nose; during breathing, outside air enters the second accommodating groove (23) through the first vent hole (231), is filtered through the bamboo charcoal adsorption plate (71) and the activated carbon adsorption plate (72), and is discharged into the third accommodating groove (24) through the second vent hole (232), and then the filtered air enters the winding drum (63) from one end of the opening of the winding drum (63) and then enters the oxygen pipe (82), so that constructors can inhale the purified air to avoid poisoning; after the oxygen hose is used, the handle (62) can be rotated, so that the oxygen hose (82) is wound on the winding drum (63) again, and the limit knob (621) is screwed down;
the gas monitoring alarm shell (4) is completely embedded into the fixing frame (1), and a shifting plate (41) is vertically arranged on the outer side edge of the bottom surface of the gas monitoring alarm shell (4).
