Abstract

The invention discloses a protecting, fixing and retracting integration device of an acoustic emission deep hole monitoring sensor. The device consists of a sensor protecting sleeve, a fixing device of the sensor protecting sleeve, a guider, a mounting rod, a directional ring and a rotary disc. The front end of the sensor protecting sleeve is connected with the fixing device of the sensor protecting sleeve by counterclockwise screws. The tail part of the sensor protecting sleeve is connected with the guider by clockwise screws, and is connected with the mounting rod through a pin and a unidirectional clamping groove. The directional ring is fixed at the front end of the mounting rod. The rotary disc is mounted on the tail part of the mounting rod. During retracting, the rotary disc facilitates the mounting rod to screw the sensor protecting sleeve off the fixing device of the sensor protecting sleeve. The device can better overcome the defects of insufficient protection, simple mounting angle and large absence or deflection of the monitored data due to untight coupling of the sensor and the rock existing in the traditional sensor, solves the problem of difficult retracting of the sensor in deep hole mounting, can be widely applied to rock engineering of tunnels, underground chambers, mine underground stopes, roadways and the like, and has great economical benefit.

Description

technical field [0001] The invention belongs to the technical field of deep hole monitoring, and more particularly relates to an integrated device for protection, fixation and recovery of acoustic emission deep hole monitoring sensors, which is mainly used for sensors, preamplifiers and their connection lines in the process of acoustic emission deep hole monitoring on rock engineering sites The device can be widely used in tunnels, underground caverns, underground stopes, roadways and other rock engineering support measures, support timing selection and evaluation, engineering geological disaster monitoring, evaluation and analysis and other fields. Has a wide range of engineering application value. Background technique [0002] With the rapid development of the national economy, resource development and infrastructure construction are advancing at an unprecedented speed. The development of hydropower resources is in full swing in the deep mountains and canyons in the mount...
