Abstract

The invention relates to a coal mine underground water control alarm comprising a case and a partition disposed in the case. An inner cavity of the case is divided into an upper cavity and a lower cavity by the partition. A whistle is disposed in the upper cavity. A gas generator and a central controller are disposed in the lower cavity. An outlet of the gas generator is communicated with an inlet of the whistle through a pipeline. A seepage detector is disposed besides the case and comprises a panel. A plurality of seepage probes are disposed on the front end face of the panel. A data collection box for collecting data acquired by the seepage probes is disposed on the rear end face of the panel. The change of water content of mud is monitored through the seepage probes, the water change data from the seepage probes is transmitted to the data collection box, the central controller controls the gas generator to operate when the acquired data reaches the preset value, gas is lead into the whistle through the gas generator so that the whistle sounds and sends out an alarm, and miners can be evacuated timely.

Description

technical field [0001] The invention relates to an early warning device for water prevention and control in underground coal mines. Background technique [0002] At present, when working underground in coal mines, due to the harsh working environment, some safety accidents inevitably occur, and large-scale catastrophic accidents also occur from time to time. Especially when there is a gas overrun or outburst accident, there will be a partial power outage, and the original electric alarm will not work normally due to power outage; in this way, the staff cannot understand the dangerous situation in time, and the final time for safe evacuation will be delayed. At the best time, it often results in serious casualties. Therefore, the existing electric alarm device cannot accurately send the danger alarm signal under the partial power failure situation, causing unnecessary safety accidents, which is the deficiency of the prior art. [0003] At present, it is not possible to do a...
