Abstract

The invention provides a multi-point displacement meter capable of automatically measuring space displacement. The multi-point displacement meter comprises an anti-explosion online monitoring terminal, an anti-explosion Bluetooth emitter, a space displacement sensor, a wire, a drilling rod, a fixed ratchet and an end drilling rod. According to a to-be-measured rock stratum separation layer, an offset position and depth of a drilling hole, length of the drilling rod is adjusted. Then, the drilling rod part is completely inserted into the drilling hole, and a reference plate tightly clings to surrounding rock. When a separation layer and offset occur in each rock stratum, a rotation small ball in the space displacement sensor rotates, a displacement telescopic rod is extended, and the space displacement sensor transmits a signal to the anti-explosion online monitoring terminal for processing and then stores the data. During data acquisition, the data is transmitted into a collector through the anti-explosion Bluetooth emitter. By combining the space displacement sensor, the drilling rod, the anti-explosion online monitoring terminal and the Bluetooth device, the movement rule of surrounding rock in the space can be precisely and properly researched, measurement is real and installation is easy.

Description

technical field

[0001] The invention relates to the technical field of multi-point displacement meters, in particular to a multi-point displacement meter for automatically measuring spatial displacement. Background technique

[0002] Most of the multi-point displacement gauges currently used in coal mines are based on measuring the length of steel wire ropes. By calculating the length difference between two steel wire ropes, the separation of each rock layer inside the surrounding rock is estimated. This kind of multi-point displacement gauge is A relatively primitive test tool, which can only roughly measure the layer separation of surrounding rocks, and provide data support for the study of deep surrounding rock displacement laws.

[0003] However, during the installation process of this multi-point displacement meter, the wire rope is prone to a series of problems such as winding, bending, and breaking, and the result obtained has a large error, and the result is only the...
