Abstract

The invention discloses an active high-flow drainage device. The active high-flow drainage device comprises a water collecting tank, a filter screen in the water collecting tank, and a control circuit. A high-water-level contact switch and a low-water-level contact switch are arranged at the upper end and the lower end of the side wall of the water collecting tank respectively; a water outlet of the water collecting tank is communicated with a water inlet of a pneumatic-and-hydraulic mixing cylinder through a pipeline; the air-and-hydraulic mixing cylinder is divided into a pneumatic cylinder on the left side and a hydraulic cylinder on the right side, and a pneumatic piston and a hydraulic piston are connected to the same piston rod; a drainage outlet is formed in the lower side of the right end of the hydraulic cylinder. Pneumatic power is fed into the pneumatic cylinder, and the pneumatic piston drives the hydraulic piston to carry out reciprocating motion so that water suction and drainage operation can be carried out. According to the active high-flow drainage device, slag can be efficiently filtered out, stable high-flow drainage operation can be carried out, automatic drainage operation can be actively carried out, drainage efficiency is improved, the slag is effectively filtered out, blocking failures are avoided, small waste slag can be drained in a forced mode, and the maintenance and cleaning frequency is reduced.

Description

[0001] technical field [0002] The invention relates to a mine drainage device, in particular to an active large-flow water discharge device. Background technique [0003] Existing water discharge devices commonly used in underground mines are all mechanical. Mechanical drainage equipment has a high failure rate in actual use, and its water discharge is small, which cannot meet the efficient and stable drainage requirements in mines. From the point of view of actual use, the use of mechanical automatic water release devices in the low-lying drilling site inside the channel can meet the water discharge requirements, but from the perspective of the water discharge effect of the layer-penetrating drilling and the main pipeline on the ground, the mechanical water release device not only cannot meet the water discharge requirements of the drilling site. It is very easy to be blocked by waste slag and lose the water discharge function, resulting in drainage operation failure and ...
