Abstract

The invention relates to a convex reflector indicator light outside the mine rescue cabin, in particular to a reflective indicator light which uses the principle of mirror reflection to transmit the light signal from the mine rescue cabin to other directions, and belongs to the coal mine safety technology field. It uses the principle of mirror reflection to transmit the information of the miner's light emitted from the rescue cabin to the positive and negative directions at a set angle with the light, so that rescuers can clearly find the location of the rescue cabin and play the role of an indicator light. It includes a miner's lamp, a launch window seat, a mirror frame, and a reflector. The miner's lamp is placed at the inner end of the light emission hole; two reflectors are arranged outside the rescue cabin; Located in the axial center plane of the light emitting hole, the included angle between the two reflecting mirrors is 90°, and the included angle between the two reflecting mirrors and the axial center plane of the light emitting hole is 135°; A red transparent body at right angles to the axis. The invention has the advantages of reasonable design, simple structure, economical and practical, and obvious indicator lights.

Description

technical field [0001] The invention relates to a convex reflector indicator light outside the mine rescue cabin, in particular to a reflective indicator light which uses the principle of mirror reflection to transmit the light signal from the mine rescue cabin to other directions, and belongs to the coal mine safety technology field. Background technique [0002] In the event of a coal mine accident, in order to enable rescuers to immediately and accurately find the distressed miners hiding in the mining rescue cabin, it is specified in the "General Technical Conditions for Mine Rescue Cabin" formulated by the State Administration of Work Safety Regulations: there should be an external indicator light outside the rescue cabin, and the indicator light should be intrinsically safe, adapt to the requirements of the environment, and have corresponding safety protection. It is advisable to use a high-penetration light source. Existing mining rescue cabins cannot meet the above-...
