Abstract

The invention discloses a strain type intelligent inclinometer, which comprises a rectangular shell (1), a force transfer rod (2), mass blocks (5), electric resistance strain gauges (3), a sliding layer (4), an end cover (6) and a detection circuit. The strain type intelligent inclinometer provided by the invention is laminated with the surface of a structure through the contact surface (7) of theinclinometer; if an inclination angle exists on the surface of the structure, the mass blocks of the inclinometer provided by the invention can generate downward sliding force under the action of gravity to act on the force transfer rod; the force transfer rod generates elastic deformation under the action of external force; the electric resistance strain gauges stuck on the surface of the forcetransfer rod also generate deformation in an accompanying manner; after the electric resistance strain gauges generate the deformation, the resistance value is about to be changed; the electric resistance variation is converted into a voltage variation, namely an electric signal, via a corresponding measuring bridge circuit; thus, the process of converting the change of the inclination angle intothe electric signal is realized, and through the positive and negative values of two electric resistance strain gauges on the force transfer rod, the inclination direction is accurately judged.

Description

technical field [0001] The invention relates to a strain type intelligent inclinometer, which belongs to the technical field of civil engineering structure detection. Background technique [0002] As an important content in the field of civil engineering, structural inspection has attracted more and more people's attention. The inclination of the surface of the structure is not only related to the external appearance of the structure, but more importantly, it will affect the safety and stability of the overall structure. Therefore, in some parts that require relatively high flatness and verticality, inclinometer measurement is particularly important. [0003] At present, traditional inclinometers are basically composed of a gravity pointer, a dial, and a measuring base. They are designed using the gravity characteristics of the pointer, and the accuracy is not high and the durability is poor. The strain-type intelligent inclinometer, when the inclination angle of the struc...
