Electricity-saving type real-time automatic monitoring instrument for terrane displacement

Abstract

The invention relates to an energy-saving rock stratum displacement real-time automatic monitoring instrument, which comprises a displacement sensing unit, an information acquisition and processing unit and a stay tensioning mechanism. The structure of the displacement sensing unit is as follows: both ends of a rotary shaft are fixed on a supporting plate and a shell respectively; an isolating disc is arranged in the middle of the rotary shaft; and a displacement transmission mechanism, a coded disc and a transferring support plate are arranged on the rotary shaft on both sides of the isolating disc in turn from the inside to the outside. The displacement transmission mechanism comprises the following two modes: one is stay transmission mode, and the other is gear and rack transmission mode. The energy-saving rock stratum displacement real-time automatic monitoring instrument realizes electroless operation in the state that a rock stratum has no displacement, is instantaneously connected with a high-resistance circuit when the rock stratum has measurable displacement, outputs corresponding measurable pulse signals and starts the information acquisition and processing unit; and the whole measuring process realizes rock stratum displacement measurement with energy conservation and low energy consumption.

Description

technical field [0001] The invention relates to a measuring instrument, in particular to an electricity-saving real-time automatic monitor for rock formation displacement. Background technique [0002] At present, there are many types of sensors and monitors for detecting displacement in engineering, each with its own characteristics and scope of application. Monitoring and forecasting instruments are rare, especially the real-time automatic monitoring of high precision and large displacement is almost blank. There is still a lack of reliable, real-time automatic monitoring and forecasting instruments for safety accidents caused by roof fall, bottom slump, and rockburst caused by internal displacement changes in the roof (bottom) slab and coal pillars, especially in coal mining. A power-saving real-time automatic monitoring and forecasting instrument to realize uninterrupted real-time automatic monitoring and forecasting of underground roadway displacement on the ground. ...
