The water-soluble paper tape 24 will slowly break when it meets water. After the water-soluble paper tape 24 breaks, the rotating plate 22 rotates under the action of the torsion spring so that the tip of the rotating plate 22 contacts the hole wall, and the tube body 3 is controlled to rotate in the opposite direction through the cover plate 31, so that the tip of the rotating plate 22 will be inserted into the hole wall, so that the tube body is firmly installed, the inclinometer tube will not move during use, and the detection accuracy is high.

[0033] The cover plate 31 is provided with a guide hole, in which a guide rod 7 is reciprocatingly slidably connected. The lower end of the guide rod 7 extends into the interior of the tube body 3. The lower end of the guide rod 7 is fixedly connected to an annular box 71. A pressure relief hole is provided on the upper side of the annular box 71. Dry powder is contained in the annular box 71.

[0035] A baffle plate 75 is fixedly connected to the middle part of the guide rod 7, a return spring 76 is fixedly connected between the baffle plate 75 and the cover plate 31, a telescopic rod 77 is fixedly connected to the upper end of the guide rod 7, a through groove 78 is provided on the inner wall of the extension tube 6, the telescopic rod 77 can be extended from the through groove 78, a first arc block 79 is fixedly connected to the upper side of the telescopic rod 77, a plurality of second arc blocks are fixedly connected to the bottom of the lifting platform 1 in a circular array with the drive ring 11 as a reference, and the second arc blocks can contact the first arc block 79.

In the process of the extension tube 6 driving the tube body 3 to rotate and lower, the second arc block interacts with the first arc block 79 to make the guide rod 7 rise and fall periodically. In the process of the guide rod 7 rising and falling, the annular box 71 at the lower end of the guide rod 7 leaks dry powder from the blanking hole 73, which combines with the water droplets on the inner wall of the pre-drilled hole to avoid water droplets splashing onto the water-soluble paper tape 24 during the lowering of the tube body 3, causing the rotating plate 22 to unfold prematurely, making it impossible to place it in the predetermined position, thereby improving the stability of the device.

[0037] During operation, the hoisting platform 1 is hoisted above the pre-drilled hole, the avoidance groove 32 of the cover plate 31 is aligned with the slide bar 63, and then the tube body 3 is rotated, the slide bar 63 enters the slot 33 and is blocked by the limit surface 331, so that when the drive ring 11 is rotated, the tube body 3 can be rotated and lowered to reduce the resistance of the tube body 3 being lowered. After the tube body 3 reaches the predetermined position, the drive ring 11 is rotated in the opposite direction, and the slide bar 63 slides back into the avoidance groove 32. At this time, the extension tube 6 can be removed, so that the inclinometer tube 10 can be placed at different depths, which is convenient to use.

[0038] The tube body 3 rotates to descend, and when the push rod 262 contacts the bottom of the hole, as the tube body 3 continues to descend, the push rod 262 pushes the piston ring 261 to push water into the cavity, and then falls on the water-soluble paper tape 24 through the water spray hole 252. The water-soluble paper tape 24 will slowly break when it meets water. After the water-soluble paper tape 24 breaks, the rotating plate 22 rotates under the action of the torsion spring so that the tip of the rotating plate 22 is embedded in the hole wall, and then the tube body 3 rotates in the opposite direction, so that the tip of the rotating plate 22 is inserted into the hole wall, so that the tube body is fixed at the corresponding depth, so that it can be tilted along with the formation, and the detection accuracy is high.
