Description
Technical Field
The utility model relates to the technical field of coal mine safety, in particular to an underground warning lamp.
Background
The underground tunnel of the coal mine lacks natural light and is illuminated by an illuminating lamp. Some locations are inconvenient to wire, such as gateroad face up and down galleries often lack lighting devices, which can easily cause collision accidents for passing people or vehicles, such as for example, for equipment or vehicles parked in the galleries. For this reason, battery-powered warning lights are required at these locations to avoid collision accidents. In addition, articles temporarily stored in the pit sometimes occupy part of the traffic space, and especially after the articles are scattered or even collapsed, the traffic safety is endangered.
The warning lighting lamp emits light for a long time, the battery needs to be replaced frequently, and the use is troublesome; if the battery is not replaced in time, safety accidents are easily caused.
Increasing the battery charge can prolong the battery power supply time, prolong the period of battery replacement, and alleviate the trouble of frequent battery replacement, but increasing the battery charge requires increasing the battery cost and increasing the weight of the battery (heavier batteries are less portable and inconvenient to replace).
Another technical idea is to use a sound control lamp. The voice-controlled lamp is adopted, the warning lamp is turned on when the voice exists, and is turned off when the voice does not exist, so that the warning lamp does not need to be kept continuously on, and the electric quantity is saved. This seemingly perfect technical idea is practically impossible downhole because: 1. when in downhole operation, the noise is large, so that the sound control lamp is just turned off and on, and the electricity saving meaning is not achieved. 2. The vehicle is in a place far away from the working area and the noise source, and the warning lamp only lights when the vehicle needs to approach the warning lamp although the noise is smaller; if the vehicle needs to evade equipment parked near the illumination lamp at this time, it may not be possible. Thus, the voice control scheme is of little practical value downhole.

The light sets up on the tunnel roof. The starting unit comprises a first film pressure switch, a second film pressure switch and a normally open contact of a starting relay which are connected in parallel; the lighting control unit comprises a coil of a starting relay, a coil of an illuminating lamp and a coil of a time relay which are connected in parallel;
and a normally closed contact which is disconnected by the power-on delay of the time relay is also connected in series between the starting unit and the lighting control unit, and the power-on delay of the normally closed contact which is disconnected by the power-on delay of the time relay is 1 minute.
A low-voltage alarm is connected between the anode and the cathode of the storage battery, and the low-voltage alarm is provided with a loudspeaker for sounding.

Because the time of unmanned vehicle is at least several times (even tens times) of that of someone or vehicle under normal condition, the period of replacing or charging the battery after adopting the utility model is greatly prolonged, avoiding the trouble of frequently replacing or charging the battery.
The highest speed of the vehicle in the roadway is not more than 30 km/h (the upper speed limit specified by many mines is 20 km/h), the safe braking distance of the speed of the vehicle is about 9.5 m (the setting position of the illuminating lamp is not necessarily required to brake the vehicle), the distance between the two film pressure switches and the illuminating lamp is 30+/-5 m, the safe and sufficient speed reduction passing or braking distance is provided, and the passing safety of the vehicle is ensured.
The illuminating lamp is positioned at a high place, so that the traffic route in the roadway can be comprehensively illuminated, and the problem that eyes directly look at the illuminating lamp to obstruct vision is avoided.
