The second fixed block of the steering pulley, the four steering pulleys are connected with wires, and the fixed shaft is slidably connected with a sensor to achieve more intensive depth measurement, easy to measure accuracy, effect and range, and a high degree of convenience.

Description

technical field [0001] The invention relates to the field of monitoring systems, in particular to an intelligent traction type deep level displacement monitoring system based on an automatic lift inclinometer. Background technique [0002] The inclinometer is a monitoring instrument used to monitor the apex angle and azimuth angle of geotechnical structures such as foundation pits, foundations, walls and slopes. It can obtain the horizontal displacement of the soil layer by measuring the inclination angle of the borehole. Changes have played an important role in ensuring the safety of geotechnical engineering design, construction and use. [0003] The principle of the fixed inclinometer is: a gravitational accelerometer, which measures the component of the earth's gravity in the measurement direction. It can measure the inclination changes in both X / Y directions at the same time, so that the inclination direction and inclination angle of the point can be obtained through ca...

AI Technical Summary

Problems solved by technology

[0005] The current fixed inclinometer has the following disadvantages: (1) the current fixed inclinometer is limited by the sensor spacing and the connector device and cannot measure the deformation state of the entire underground measuring pipe; (2) the current fixed inclinometer During the installation and debugging process of the inclinometer, the sensors need to be put into the tube one by one and connected with connectors one by one. The installation process is more complicated and the measurement accuracy is low; External power supply, external communication device, and supporting equipment are complicated. In case of line failure, it needs to be reinstalled and debugged; (4) During the measurement process, in case of sensor failure, all sensors and parts need to be taken out and replaced again. The data will be poorly connected and need to be recalculated, resulting in unavoidable precision errors
