Description

Technical Field

[0001] The utility model belongs to the technical field of water prevention and control early warning, and specifically relates to a coal mine geological underground water prevention and control early warning device. Background Art

[0002] Underground mining refers to a mining method in coal mining that corresponds to open-pit mining. The hydrogeological conditions of my country's coalfields are complex, and due to the influence of groundwater and rainwater, there will inevitably be water in coal mines. Therefore, drainage devices will be installed in coal mines. In order to facilitate the measurement of water levels in coal mines and drainage, water prevention and control early warning devices will be installed in mines. The coal mine geological underground water prevention and control early warning device in the prior art is mainly composed of a foam plate, a sealing cylinder and an alarm. The foam plate is slidably connected to the bottom of the sealing cylinder, and the alarm is installed on the top of the sealing cylinder. When the water level rises, the position of the foam plate in the sealing cylinder rises. When the foam plate rises to a certain height and contacts the alarm switch, the alarm is turned on, thereby reminding the workers in the coal mine that the water level has reached a dangerous level and needs to be evacuated or the output power of the drainage device is increased. However, on rainy days, rainwater gathers into underground groundwater. Affected by the complex environment in the coal mine, the underground groundwater will produce waves when it flows. The height of the foam plate will fluctuate when it is impacted by the waves, which can easily touch the contact switch by mistake, resulting in inaccurate alarm of the alarm. Utility Model Content

[0003] The purpose of the utility model is to provide a coal mine geological underground water prevention and control early warning device to solve the problems raised in the above background technology.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

When the water level in the mine rises to a certain height, the floating plate on the third trigger module at the bottom conflicts with the contact switch as the water level rises, and the alarm is turned on to issue a first-level alarm. The single-chip microcomputer controller controls the wireless transceiver module to send a first-level alarm signal to the outside world.
