1. A recyclable inclination measuring device, comprising measuring units arranged in a linear array during installation, wherein two adjacent measuring units are eccentrically hinged by a joint;
during a measurement, the measuring units are arranged in a Z shape in a measuring tube, an inner wall of the measuring tube is closely attached to the joint, and the measuring units extending out of the measuring tube are folded and arranged;
the joint includes a flexible hinge joint and a rigid hinge joint arranged in an axisymmetric manner, and cross sections of the flexible hinge joint and the rigid hinge joint are both right-angled triangular structures;
a tip of the flexible hinge joint and a tip of the rigid hinge joint are rotationally connected by a hinge shaft;
the flexible hinge joint is made of a flexible material with deformation, and the rigid hinge joint is made of a rigid material without deformation;
two ends of each of the measuring units are arranged with the flexible hinge joint and the rigid hinge joint respectively, and the flexible hinge joint and the rigid hinge joint on the same measuring unit are arranged symmetrically;
each of the measuring units includes a rigid rod;
a first right angle surface of the flexible hinge joint and a first right angle surface of the rigid hinge joint are fixedly connected with the rigid rod, and a second right angle surface of the flexible hinge joint and a second right angle surface of the rigid hinge joint are respectively flush with symmetrical sides of the rigid rod.
