AI Technical Summary

Technical Problem

Existing mine pressure monitoring devices are difficult to adapt to boreholes of different diameters and are susceptible to electromagnetic interference and high humidity in underground coal mines, resulting in distorted measurement data and failing to meet the needs of long-distance distributed monitoring.

Method used

Using a fiber optic stress sensor as the core component, combined with a self-locking structure of limiting teeth and limiting pins, the device can adapt to different apertures by adjusting the position of the top block, and achieve self-locking under the elastic force of the elastic element, ensuring that the sensor works stably in complex environments.

Benefits of technology

It enables convenient installation of mine pressure monitoring devices in boreholes of different diameters, improves the reliability and anti-interference ability of measurements, and meets the needs of long-distance distributed monitoring.

Abstract

The utility model relates to mine pressure monitoring technical field, concretely relates to a roadway mine pressure monitoring device. The device includes connecting piece and at least two monitoring rod bodies, is equipped with stress sensor on the monitoring rod body, is equipped with a plurality of limit teeth on the monitoring rod body along the longitudinal direction, the other end of monitoring rod body swing joint has the top block, is set up in the through -hole of the top block and is set up in the limit slot of the limit tooth passes through and is set up in the groove bottom of limit slot and is set up in the inclined hole, the inclined hole is swing joint in the limit pin, and the limit pin is connected with the inclined hole through the elastic part, when the top block is away from the connecting piece movement, the limit tooth can top into the inclined hole in the limit pin, when the top block is close to the connecting piece movement, the limit pin can resist on the limit tooth. When installing mine pressure monitoring device, by adjusting the distance of the top block away from the connecting piece, can adapt to the drill hole of different aperture, and installation is more convenient and fast.
