Embodiment 1
[0027] Embodiment 1, as figure 1As shown, the coal and rock mass stress directional monitoring device of the present invention is mainly composed of a three-way cylinder pressure sensor 1, a high-pressure oil pipe 2 and a three-way valve 3. The high-pressure oil pump 9 and the installation guide rod 4 are used as supporting tools. The sensor 1 is installed in the coal rock mass by installing the guide rod 4, and the cylinder body pressure sensor 1 is provided with three piston induction plates, and the three piston induction plates are respectively connected through the fixing nut 11 to each independently installed in the cylinder body pressure sensor. The piston cylinder in 1, the three piston induction sheets include the first piston induction sheet 6-1, the second Piston induction piece 6-2 and the third piston induction piece 6-3; The junction of cylinder body pressure sensor 1 and installation guide rod 4 is provided with installation rod joint 10, and installation rod jo...
Embodiment 2
[0037] Embodiment 2. According to the actual monitoring needs, if only one direction needs to be monitored, only one piston sensing plate and the piston cylinder connected to it can be set on the cylinder body pressure sensor 1, such as image 3 shown. Others are the same as in Embodiment 1, omitted.
Embodiment 3
[0038] Embodiment 3, according to the actual monitoring needs, if only two directions need to be monitored, only two piston sensing plates and the piston cylinders respectively connected to it can be arranged on the cylinder body pressure sensor 1, such as Figure 4 shown. Others are the same as in Embodiment 1, omitted.
