The axis of the second rotating shaft 5 is perpendicular to the axis of the first rotating shaft 3, thereby achieving free rotation in two degrees of freedom. The pointer 6 is mounted on the second rotating shaft 5 to drive the second rotating shaft 5 to rotate. The first angle sensor 7 is mounted on the bending plate 4, with the detection end of the first angle sensor 7 facing the second rotating shaft 5 and used to detect the rotation angle. A first coupling 8 is mounted between the detection end of the first angle sensor 7 and the second rotating shaft 5, ensuring synchronous rotation of the detection end of the first angle sensor 7 and the second rotating shaft 5. An electric telescopic rod 9 is mounted between the bottom wall of the support tube 1 and the first sealing cover 2, located inside the support tube 1, and is used to provide a driving force to adjust the relative position of the first sealing cover 2 and the support tube 1. Driven by the electric telescopic rod 9, the pointer 6 moves in and out of the support tube 1.

[0038] The embodiment of the present disclosure provides a slope surveying device, which controls the operation of the electric telescopic rod 9 to drive the sealing cover to move, and finally the pointer 6 to move out of or into the support tube 1. When the pointer 6 moves out of the support tube 1, slope surveying can be performed. When the pointer 6 moves into the support tube 1, protection can be performed. After the pointer 6 moves out of the support tube 1, under the action of gravity, the pointer 6 will automatically deflect, and then drive the second rotating shaft 5 to rotate. Through the first coupling 8, the first angle sensor 7 can detect the rotation angle of the second rotating shaft 5, and then derive the deflection angle of the pointer 6, thereby automatically completing the slope surveying work. Compared with the method of reading with the human eye, the operation is simple and human errors are eliminated. Moreover, under the drive of external force, the first rotating shaft 3 can rotate, and finally the direction of the pointer 6 is changed, thereby completing the slope detection work in different directions, making the surveying data more comprehensive.
