An underground reservoir drainage system and its control method

Abstract

The invention discloses an underground reservoir drainage system. The underground reservoir drainage system includes a settling pond, a water inlet pipe and a water outlet pipe; a drainage pump is arranged on the water outlet pipe; a water outlet pipe port is formed in a wall of the settling pond, and the water outlet pipe and the water outlet pipe port are in sealed connection; a water inlet pipeport is formed in a wall of the settling pond, and the water inlet pipe and the water inlet pipe port are connected; the underground reservoir drainage system also includes a drive assembly; an adjustment baffle plate which can swing vertically is arranged in the settling pond; the adjustment baffle plate is positioned under the water inlet pipe port; an angle sensor for monitoring an angle between the adjustment baffle plate and the wall of the settling pond is arranged on the adjustment baffle plate; and the angle sensor is in communication connection with a control unit of the drive assembly . The invention discloses a control method of the underground reservoir drainage system. The underground reservoir drainage system and a control method thereof can remove sludge in normal working,can ensure the safety of an underground reservoir, can reduce the working load, and can improve the working efficiency.

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, which belongs to the sealed space. The underground reservoir is filled with collapsed and broken gangue. Due to the separation of loose gangue and the precipitation of suspended particles, it is easy to cause reservoir sedimentation, and the sedimentation state is difficult to observe. When pumping water with a decontamination pump, the maximum particle size cannot exceed 10mm, and Stone is different from ordinary fibers, its strength is high, it cannot be cut, and the loss of the pump is very large, which is not stable for the underground reservoir. When laying a filter in front of the pipeline, due to the accumulation of sand and stone Therefore, it is very important to find a syste...

Problems solved by technology

The underground reservoir is filled with collapsed and broken gangue. Due to the separation of loose gangue and the precipitation of suspended particles, it is easy to cause reservoir sedimentation, and the sedimentation state is difficult to observe. When pumping water with a decontamination pump, the maximum particle size cannot exceed 10mm, and Stone is different from ordinary fibers, its strength is high, it cannot be cut, and the loss of the pump is very large, which is not stable for the underground reservoir. When laying a filter in front of the pipeline, due to the accumulation of sand and stone Therefore, it is very important to find a system and method that can desilt during normal operation.
