For towering structures with small base area and large height, even if slight inclination occurs, the towering structures need to cause large horizontal component force and overturning moment under the action of huge gravity of the towering structures, the overturning moment increases the inclination of the towering structures, and the interaction of the towering structures and the overturning moment is a vicious circle, so that the towering structures are obvious in inclination deformation. Tilt angle detection of towering structures is necessary in coal mining. Therefore, it is necessary to study an inclination measuring apparatus for performing an inclination angle measuring operation for high-rise structures such as iron towers and broadcasting towers.
