Abstract
The utility model discloses an alarm relay unit for coal mine deep well methane superscale, which mainly comprises a gas alarm, a safety helmet and an alarm information wireless emitter, wherein the gas alarm and the alarm information wireless emitter are installed on the safety helmet; alarm relay units are arranged from the bottom of a coal mine to the mouth of a well; and a terminal alarm is arranged at the mouth of the well. The alarm relay unit for coal mine deep well methane superscale has the advantages of sensitiveness and stability, safety and reliability, convenience in installation and the like.
Description
Technical field the utility model relates to a kind of warning device, especially a kind of warning device that is used for underground work.
Background technology is present, and China is one of multiple country of colliery mine disaster, and the accident that wherein causes because gas exceeds standard accounts for larger proportion especially.Trace it to its cause, be because present warning device is too simple and backward, though the multi-efficiency that present safety helmet has been gathered illumination and reported to the police, but the alarm signal of gas alarm can only be transmitted about hundreds of rice to one km now, if well depth surpasses a km, alarm signal just can't reach ground fast and accurately, also therefore can't carry out Rapid Alarm.In sum, we need a kind of safer, warning device more fast especially.
The summary of the invention the purpose of this utility model provides a kind of warning relay that can exceed standard by the coal mine deep well gas that relay is strengthened alarm signal transmission.
The utility model mainly comprises gas alarm, safety helmet and warning message wireless launcher, and gas alarm and warning message wireless launcher are installed on the safety helmet; From mine bottom to well head the warning relay is installed evenly; At well head installing terminal alarm.
During use, in case fire damp exceeds standard, gas alarm on the safety helmet just can be reported to the police, and pass through the warning message wireless launcher upwards transmission of alarm signal, and the warning relay that is installed in the well can receive the next one warning relay that this signal also upwards passes to signal the top again, and the like, finally alarm signal strong pass to ground, make the ground handling personnel can in time learn the downhole safety situation and make fast reaction.
Compared with the prior art, the beneficial effects of the utility model are: sensitive stable, safe and reliable, easy for installation, can improve downhole safety warning intensity, and be convenient to ground peace pipe department and in time go and find out what's going on.
Description of drawings Fig. 1 is a mounting structure sketch of the present utility model.
The specific embodiment mainly comprises gas alarm 1, safety helmet 2 and warning message wireless launcher 3 in mounting structure sketch of the present utility model shown in Figure 1, gas alarm and warning message wireless launcher are installed on the safety helmet; From mine bottom to well head warning relay 4 is installed evenly; At well head installing terminal alarm 5.
