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.
