The invention discloses a PLC-based mining underground drainage device and a control system. Large particles are left in an adjusting assembly through a one-way plate and a bidirectional plate, so that impurities are prevented from entering into a water suction pump, so that the water suction pump is protected effectively and the service life is prolonged. Matched with a first motor, a crushing tool bit is driven to crush the large particle impurities, and matched with a fan, the impurities in the adjusting assembly are discharged from a drain outlet, so that the whole pollution discharge process is finished without detaching a pipeline and it is simple and convenient to operate. Matched with two pollution discharge connecting parts by a three-way pipe, two water flow passageways are realized. Matched with a PLC control module and a sweeping function of the crushing tool bit to the one-way plate and the bidirectional plate, initial decontamination without replacing the water flow passageways is realized. When the initial decontamination fails, the PLC control module also can determine whether the water flow passageways are switched intelligently or not according to the working state of each pollution discharge connecting part, so that drainage work can be carried out further while thorough decontamination work is executed, and therefore, the drainage efficiency is improved.
Description
technical field [0001] The invention relates to the field of drainage systems, in particular to a PLC-based mine underground drainage device and a control system. Background technique [0002] After coal mining, the remaining mined-out area is likely to form a water pond, which contains large-sized particles such as coal slag. When draining the mined-out area, a pump is used for drainage, but when draining, large-sized particles It will flow into the sump pump together with the water flow, which will cause damage to the sump pump. [0003] The patent document with the publication number CN208280985U discloses a drainage device for gobs in coal mines. By setting the tightening plate and placing it inside the bearing, the rotation of the tightening plate can be realized, and the connecting rod can’t be rotated after being stretched. The insertion rod cannot be inserted into the insertion hole so that the two drain pipes cannot be quickly connected, and the top of the sliding ...
