Abstract
The utility model discloses an alarm device for underground operation, which belongs to the technical field of underground alarm, aims at solving the problems that an audible and visual alarm device in the prior art is lack of protection and affects subsequent alarm work, and comprises a box body, an audible and visual alarm, a fixed guide rail, a movable guide rail, a movable guide rail and a power supply, the two fixed guide rails are fixed to the inner bottom wall of the box body, the inner bottom wall of the box body is slidably connected with a placement seat, and limiting blocks are fixed to the two sides of the placement seat; according to the utility model, the box body and the cover plate play a daily protection role on the audible and visual alarm, the audible and visual alarm is prevented from being collided, the stability of the cover plate is kept after the cover plate is closed through the arrangement of the limiting mechanism, the placement seat is limited through the cooperation of the insertion rod, the fixed block and the fixed guide rail, so that the audible and visual alarm is limited, and the safety of the audible and visual alarm is improved. And through communication of the first heat dissipation holes, the cavity and the second heat dissipation holes, heat dissipation of the bottom of the audible and visual alarm is facilitated.
