Abstract: A recyclable inclination measuring device includes measuring units arranged in a linear array during installation, and two adjacent measuring units are eccentrically hinged by a joint; during the measurement, measuring units are arranged in a Z shape in the measuring tube, the inner wall of the measuring tube is closely attached to the joint, and measuring units extending out of the measuring tube are folded and arranged. the present invention adopts a recyclable inclination measuring device with the above structure, during the measurement, it is placed in the measuring tube, which can be arranged in a Z shape under the action of gravity, and then it can be measured with the synchronous rotation of the measuring tube, when it is recovered, it only needs to be pulled out, which reduces the difficulty of recovery and improves the recovery efficiency.
