Abstract

The invention relates to the field of alarms, and in particular, relates to a fire disaster acousto-optic alarm comprising an acousto-optic alarm body, a mounting base, a rotating column, an auxiliarymechanism, a fixing mechanism, a dehumidifying mechanism and a bird repelling mechanism. The auxiliary mechanism used for improving the rotating stability of the mounting base is arranged on the rotating column; the auxiliary mechanism comprises an annular groove, a rotating sleeve, an annular rolling groove and a rolling wheel; the annular groove and the annular rolling groove are formed in therotating column; the annular groove and the annular rolling groove are distributed up and down, the annular groove is sleeved with a rotating sleeve which is rotatably connected, one side wall of therotating sleeve is fixedly connected with the side wall of the mounting base through a connecting block, the rolling wheel is mounted on the side wall, corresponding to the annular rolling groove, ofthe mounting base through a mounting frame, and the rolling wheel is slidably connected with the annular rolling groove. The fire disaster acousto-optic alarm provided by the invention has the advantages of rotation, dehumidification and bird repelling functions.

Description

technical field [0001] The invention relates to the field of alarms, in particular to a sound and light fire alarm. Background technique [0002] The sound and light fire alarm is used for sound alarm and flash alarm at the scene of the accident, especially for places with low visibility or smoke at the accident site. At present, fire audible and visual alarms are mostly directly installed on the indoor wall and connected to the fire detector for control. When the fire detector detects that a fire occurs, the fire audible and visual alarm will be controlled to give an alarm. [0003] However, the existing audible and visual alarms used in forests are prone to moisture, which can easily cause a short circuit in the main board circuit in the alarm, and because there are many birds in the forest, the audible and visual alarms are easily damaged, which in turn affects the normal operation of the alarm components. Work. Therefore, it is necessary to provide a sound and light fi...
