DETAILED DESCRIPTION

[0015] The embodiments of the present invention will be described below with reference to the accompanying drawings.

[0016] A portable geological rock stress measuring device, such as Figure 1 and Figure 2 As shown, it includes a mounting plate 1, a connecting piece 2, a rotating frame 3, a supporting foot 4, a detector 5, a data line 6, a fixing piece 7, a fixing rod 8, a knob 9, an extension rod 10, a protector 11, a seismic wave generator 12, a data processor 13 and a buckle 14. Six connecting pieces 2 are connected to the lower side of the mounting plate 1, and a rotating frame 3 is rotatably connected between two adjacent connecting pieces 2. The lower side of the rotating frame 3 is rotatably connected to the supporting foot 4, and the detector 5 is connected to the supporting foot 4. The detector 5 is connected to the data line 6. The upper and lower parts of the rotating frame 3 are connected to the fixing piece 7, and the data line 6 is connected to the adjacent fixing piece 7. The fixing piece 7 is connected, and a fixing rod 8 is connected to the lower side of the middle part of the mounting plate 1. A knob 9 is threadedly connected to the lower part of the fixing rod 8. The knob 9 is provided with anti-slip grooves for easy rotation. An extension rod 10 is slidably connected to the inside of the fixing rod 8. The diameter of the extension rod 10 is smaller than that of the fixing rod 8, which is convenient for sliding in the fixing rod 8. A protector 11 is connected to the lower side of the extension rod 10. The protector 11 is a conical structure for easy insertion into the rock formation. A seismic wave generator 12 is connected to the inside of the protector 11. A data processor 13 is connected to the upper side of the mounting plate 1, and the data lines 6 are all connected to the data processor 13. A buckle 14 is connected to the inner side of the rotating frame 3.

[0017] When using the utility model, firstly, the buckle 14 is engaged with the fixing rod 8 to make the rotating frame 3 folded and fixed, and then the device is moved to the geological rock formation stress measurement area. After reaching the measurement position, the rotating frame 3 is rotated and opened on the connecting piece 2, and the buckle 14 is separated from the fixing rod 8. Then the supporting foot 4 is contacted with the ground, so that the rotating frame 3 is placed on the ground. When it is necessary to measure the geological rock formation stress, the supporting foot 4 is rotated to insert the detector 5 into the rock formation, and then the knob 9 is rotated to move the knob 9 upward in the fixing rod 8. Then, the length of the extension rod 10 is adjusted by sliding to insert the protector 11 into the rock formation. After the knot is completed, the knob 9 is moved downward to fix the extension rod 10, and then the seismic wave generator 12 is started to transmit seismic waves to the rock formation, and the seismic waves reflected from the rock formation are received by the detector 5, and then the seismic wave data is transmitted to the data processor 13 through the data line 6. The fixing part 7 fixes the data line 6, and the seismic wave data is processed by the data processor 13 to obtain the stress state of the geological rock formation, thereby measuring the stress of the geological rock formation, so as to evaluate the stability of the underground structure, predict geological disasters and optimize the engineering design.
