Abstract

The invention relates to a methane alarm apparatus protection structure which comprises a protection cover shell, a filling air bag piece and an alarm apparatus body so as to avoid sparks in the opening and closing process of the protection cover shell. The protective cover shell comprises a bearing box body, an observation door and a blade piece, the bearing box body is arranged on the outer side of the alarm instrument body, the blade piece is arranged on the inner side of the observation door and is rotationally connected with the observation door, and the observation door is rotationally connected with the bearing box body and is arranged on one side of the bearing box body. The blade piece is additionally arranged to be matched with the observation door, so that even if the alarm instrument is used underground, the situation that impurities in air are attached to the alarm instrument body and consequently the methane content cannot be checked can be effectively avoided, meanwhile, protection on the alarm instrument body is improved, and the service life of the alarm instrument body is effectively prolonged.

Description

technical field [0001] The invention relates to the technical field of methane alarms, in particular to a protective structure for methane alarms. Background technique [0002] With the improvement of the mining efficiency of mining resources, mining has gradually penetrated into deeper strata. Since most of the mineral resources are associated with methane, the methane content often needs to be observed at any time during underground mining operations to avoid explosions due to excessive methane content. . However, because methane in nature is a colorless and odorless gas at normal temperature and pressure, it is difficult to find that the methane concentration is at a dangerous limit in time during mining. observe. However, due to the harsh mining environment during mining, the methane alarm is prone to damage in the underground, resulting in the failure of the methane alarm and the loss of methane monitoring. Therefore, an improvement is urgently needed. Contents of t...
