Description

Technical Field

[0001] The utility model relates to the technical field of engineering construction detection, in particular to a mobile inclinometer. Background Art

[0002] Mobile inclinometer is a kind of measuring instrument that has been commonly used to measure deep displacement and internal displacement. It is used in construction projects such as buildings and subway foundation pits to measure the internal deformation of soil. Its basic principle is to use the angle change of each measuring point (spacing 0.5m) and fixed spacing to calculate the horizontal and cumulative displacement using trigonometric functions. Traditional mobile inclinometers are generally composed of an inclinometer probe, a cable, and a data acquisition host. The inclinometer probe is connected to the host through a cable, and the inclinometer probe and cable are connected with waterproof aviation plugs for easy plugging and unplugging.

[0003] During the inspection, the inclinometer probe is inserted into the inclinometer tube, and the guide wheel on the inclinometer probe is embedded in the guide groove on the inner wall of the inclinometer tube, and the inclinometer probe slides along the guide groove to complete the inspection; if the connection of the aerial plug is not standardized, it is easy to cause water leakage at the aerial plug interface, affecting the normal operation of the internal components of the inclinometer probe; and, due to construction reasons, there may be dirt and other debris in the guide groove of the inclinometer tube, which affects the normal sliding of the guide wheel and easily affects the measurement accuracy of the inclinometer probe. In addition, when the inclinometer probe is extended to the bottom of the inclinometer tube, it will collide with the bottom of the inclinometer tube to a certain extent. After long-term use, it is easy to cause unstable connection of electronic components inside the inclinometer probe, affecting the measurement accuracy of the inclinometer probe.
