Description

Technical Field

[0001] The utility model relates to the technical field of mine drainage, in particular to a safety controller for a mine drainage system. Background Art

[0002] Mine drainage refers to the removal of groundwater and surface water entering the mine during the construction and production of the mine, and is one of the important means to overcome water hazards. When the water-filled ore bed is not completely drained, it is necessary to rely on drainage to create a good working environment for mining work and the health and safety of workers to ensure the smooth progress of production. In the construction and production of coal mines, water from various sources continues to flow into the mine. The accumulation of mine water in the tunnel not only affects production, but also threatens the health and safety of underground workers. Therefore, the task of mine drainage equipment is to discharge these mine waters to the ground in time, create a good working environment for underground production, ensure the safety of underground workers and the good operation of mechanical and electrical equipment. Therefore, the drainage equipment must be safe, reliable and economical. Even if the main drainage equipment installed underground has an accident in a very short time, there will be a danger of flooding the tunnel. In order to ensure safe production underground, the following requirements are put forward for the main drainage equipment: the drainage equipment must ensure that the water gushing in the mine within 24 hours is drained out within 20 hours to reserve spare time; the drainage equipment should have spare capacity to ensure replacement use and maintenance in the event of an accident, and it must also meet the needs of removing the maximum gushing water; the pump room of the main drainage equipment should have measures to prevent sudden flooding by gushing water; the main drainage equipment should work at the highest possible efficiency; the main drainage equipment must work safely, reliably and economically to ensure safe production in the mine.

[0003] In view of this, we propose a safety controller for the underground mine drainage system. When the main pump is abnormal and water accumulates, the floating plate moves up to trigger the switch signal. The microcontroller sends emergency response instructions in real time according to the switch signal. The drainage system turns on the warning light and buzzer alarm according to the emergency response instructions, shuts down the main pump to prevent further damage and leakage, and starts the auxiliary pump for emergency drainage, which effectively improves the safety of the underground mine drainage system.
