Automatic control device for mine drainage

Abstract

The invention relates to a water pump control device, in particular to an automatic control device for mine drainage. The automatic control device comprises a magnetic limiting switch, a limiting cylinder and a control floater, the upper side and the lower side of the limiting cylinder are arranged to be open, the inner wall, close to a shaft, of the limiting cylinder is provided with a limiting sliding groove, a slideway is arranged in the middle of the limiting sliding groove, and block pieces are arrange at the upper end and the lower end of the limiting sliding groove respectively; one side of the control floater is provided with a groove, a sliding rod is installed on the inner side of the groove, a magnetic control piece is installed at the upper end of the sliding rod, the groove cooperates with the limiting sliding groove for use, and the sliding rod cooperates with the slideway for use. The automatic control device for mine drainage is simple in structure, the position of the limiting cylinder can be reasonably arranged according to particular working requirements, great convenience is brought to production, the device can achieve multilevel control, the drainage speed is reasonably controlled according to the water quantity in the shaft, and due to the action of the block pieces, the control floater can achieve the multilevel drainage function in a short stroke.

Description

technical field [0001] The invention relates to a water pump control device, in particular to an automatic control device for mine drainage. Background technique [0002] Centrifugal pumps are used for drainage in underground mines. Manual drainage has been used for a long time, which not only wastes manpower, but also due to poor sense of responsibility of some operators, the pumps often turn on and off, which leads to pump burning accidents, which not only increases production costs, but also increases production costs. And affect safe production. [0003] The date of application is April 13, 2010, and the patent application number 2010201563206.3 solves the above problems better, but the device is expensive and inconvenient to install and use. Once installed, it cannot be moved, which brings difficulties to our work. Great difficulty, and this device can not realize multi-stage control, can not control the drainage speed reasonably according to the water level in the sha...
