Drainage system for underground reservoir and control method of drainage system

Abstract

The invention discloses a drainage system for an underground reservoir. The drainage system comprises a water storage container, a water suction pipe head, a first drainage pipe, a second drainage pipe, a desilting pipeline and a gravel bin, wherein one end of the first drainage pipe is connected with the water suction pipe head, and the other end of the first drainage pipe is connected with the second drainage pipe; the second drainage pipe communicates with the gravel bin, and a drainage pump is arranged on the second drainage pipe; the water storage container is connected with the first drainage pipe through a communicating pipeline; one end of the desilting pipeline and the water suction pipe head are arranged side by side, and the other end of the desilting pipeline communicates with the gravel bin; a first control valve is arranged on the communicating pipeline; a second control valve is arranged at the position, between the communicating pipeline and the second drainage pipe, on the first drainage pipe; a third control valve is arranged on the desilting pipeline, and a fourth control valve is arranged on the second drainage pipe. The invention further discloses a control method of the drainage system for the underground reservoir. According to the drainage system and the control method, the water level in the underground reservoir can be intuitively observed, meanwhile, operation under various working conditions can be realized, and thus different requirements are met.

Description

technical field [0001] The invention relates to the technical field of reservoir drainage, in particular to an underground reservoir drainage system and a control method thereof. Background technique [0002] The coal mine underground reservoir is a form of storing water resources in the goaf. It is a sealed space, and its water level is difficult to observe. The release of a large amount of toxic and harmful gases seriously affects the safe production of the mine, so the control of the water volume in the goaf is extremely important. [0003] After long-term use, the coal mine underground reservoir will accumulate silt and gravel, which will not only occupy the coal mine storage capacity and block the water flow channel, but also cause blockage of the drainage pipe on the dam body, which will be very dangerous. Therefore, if the silt and gravel accumulation point is accurately judged, how to determine The location of the dredging outlet, how to determine the state of the s...

Problems solved by technology

[0004] In the prior art, special instruments are usually used to measure the water level in the underground reservoir, which leads to the consumption of equipment and the inability to see the measured water level, resulting in sometimes deviations in the measurement results
