Background
According to the one hundred forty eight regulations of coal mine safety regulations: the air flow purification water curtain should be installed in the return airway of the underground coal mine working face.
In order to avoid the dust exceeding in the construction of the underground excavation working surface, the dust sensor gives an alarm, and the worker working clothes are drenched by spraying. Causing harm to the health of workers.
Most of domestic manual spraying devices are generally manual due to environmental particularity and restriction on various factors such as comprehensive dustproof spraying automatic dust fall, and the existing manual spraying devices are inflexible in valves and incapable of opening spraying at any time due to various reasons in the using process. Because the full automation can not be realized, the serious alarm result of the dust sensor is easy to cause.
The coal mine comprehensive dustproof work is always a difficulty of 'one ventilation and three prevention', a tunnel purification water curtain is indispensable to the comprehensive dustproof work, but due to the influences of the water pressure of pressurized water, personnel operation and the like, the use condition of the vital dustproof facility can not reach an ideal effect directly, especially the major facilities are artificially controlled and are opened untimely or closed in a delayed mode, and the dust fall effect is not obvious or the water accumulated in the tunnel is easily caused to be in a state that most of the purification water curtain arranged in the middle of the tunnel is not used.
SUMMERY OF THE UTILITY MODEL
The utility model aims at the problems mentioned in the background technology, and provides a dust concentration monitoring, watering and dust falling system device.
The specific technical scheme of the utility model is as follows: a dust concentration monitoring watering dust fall system device comprises an induction system and a waterway system; the induction system comprises a light-operated sensor, the light-operated sensor is arranged on the side of a roadway and is connected with a control box through a power cable, the control box is connected with an electric ball valve, the electric ball valve is connected with a water inlet pipeline, the tail end of the water inlet pipeline is provided with a nozzle, the nozzle is arranged at the top of the roadway, a dust concentration sensor is arranged near the nozzle and is connected with the control box; the waterway system comprises a water inlet pipeline, a manual valve, a filter and an electric ball valve are installed on the water inlet pipeline, and a nozzle is installed at the tail end of the water inlet pipeline.
Furthermore, two light-operated sensors are respectively and horizontally arranged at the positions, which are 1.3-1.5 m away from the bottom plate of the roadway, of the roadway sides of 5m-6m at the upper and lower windward sides of the spraying device, and form an included angle of 90 degrees with the wall of the roadway.
Further, the dust concentration sensor is arranged at the top of a roadway 1m-3m away from the upper wind side of the spraying device or hung on a roadway side.
Further, the manual valve is in a normally open state.
Further, the present device uses a 127V ac power supply.
Furthermore, the water pipe of the water inlet pipeline of the device adopts an 1/2 galvanized pipe or a phi 13 quick-insertion high-pressure rubber pipe.
The utility model has the following beneficial effects: 1. a manual spray valve device is not used, so that the spraying dust settling effect is prevented from being influenced by the conditions of inflexibility of a manually opened spray valve, spray blockage and the like; 2. dust concentration sensor can online real-time measurement on-the-spot dust condition and light-operated sensor response personnel through the condition to send dust fall controller to reach automatic watering dust fall through standard frequency signal, avoid constructor to drench the clothes through the spraying, effectively ensure that constructor is healthy and water economy.
