Anti-explosion indicating lamp device for preventing fire dense smoke from influencing the brightness of indicating lamp

Abstract

The invention relates to the technical field of anti-explosion indicating lamps, and discloses an anti-explosion indicating lamp device for preventing fire dense smoke from influencing the brightness of the indicating lamp, the anti-explosion indicating lamp device comprises a shell, the bottom of the shell is provided with a curved hole, the bottom of the shell is fixedly connected with an arc-shaped light shielding plate, and the top of the interior of the arc-shaped light shielding plate is fixedly connected with a light source device. According to the anti-explosion indicating lamp device for preventing fire dense smoke from influencing the brightness of the indicating lamp, when a fire occurs, the resistance value of the photoresistor is increased, the magnetic field intensity of the strong magnetic coil is further reduced, and the illumination intensity of the indicating lamp is enhanced; and therefore, the effect of preventing heavy smoke from shielding the light of the indicator lamp to affect the distinguishing of the escape route of the worker in the fire is achieved. When a fire disaster occurs, the rotating disc rotates anticlockwise, the limiting rod moves downwards at the moment, the movable contact is further made to make contact with the fixed contact, the buzzer gives out warning sound at the moment, and therefore the effect that the anti-explosion indicator lamp can give out warning when the fire disaster occurs is achieved.

Description

technical field [0001] The invention relates to the technical field of explosion-proof indicator lights, in particular to an explosion-proof indicator light device which prevents thick fire smoke from affecting the brightness of the indicator lights. Background technique [0002] Explosion-proof indicator lights are mainly used in the coal mine industry, paint or ink manufacturers, wood processing plants, cement plants, shipping and other harsh and dangerous explosive environments. They are mainly used as safety exit instructions or as safety evacuation guidance instructions during power failure emergencies For lighting, the current explosion-proof indicator light has been widely used as a light signal indicator. [0003] The explosion-proof indicator light in the prior art has a fixed light brightness, and a large amount of thick smoke will be generated in the event of a fire, thereby covering the light of the indicator light, causing the staff to be unable to correctly dis...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides an explosion-proof indicator light device that prevents the fire smoke from affecting the brightness of the indicator light. The advantage that the lamp can issue a warning solves the problem of the explosion-proof indicator light in the prior art. The brightness of the light is fixed, and a large amount of thick smoke will be generated in the event of a fire, which will cover the light of the indicator light and cause the staff to be unable to correctly distinguish the escape route. Thereby reducing the staff's escape hope, and the existing explosion-proof indicator light has no warning function, and cannot promptly and effectively remind the staff to escape when a fire occurs
