Peg-top continuous inclinometer

The utility model of a top continuous inclinometer comprises surface equipments and underground instruments, wherein, the underground instruments consist of connecting devices, protection assemblies, insulation devices, and exploring tubes, the exploring tube comprises a rotatory coasting body, a digital circuit and a secondary power hold including an accelerometer with three orthogonal axles and a gyroscope with two orthogonal axles. The utility model has the structure of protection assemblies, shock absorbers and the like, which improves the abilities of crush resistance, shock resistance and impact resistance of underground instruments of the top inclinometer, meantime, automatic north seeking and continuous measuring are realized by the synergistic action of the accelerometer with three orthogonal axles and the gyroscope with two orthogonal axles in the rotatory coasting body, and the ability of high temperature resistant of the utility model is improved through that a light source is arranged in a thermal holder and thermal insulation devices are provided. Thereby the utility model has advantages of using conveniently, avoiding the bad environment, automatic north seeking and continuous measuring.
