Device capable of enabling inclinometer probe to rotate horizontally

Abstract

The invention relates to a device capable of enabling an inclinometer probe to rotate horizontally. The device is suitable for the technical field of geotechnical engineering monitoring. According to the adopted technical scheme, the device capable of enabling the inclinometer probe to rotate horizontally is characterized by comprising an outer pipe; an inclinometer pipe coaxially inserted into the lower end of the outer pipe; the inclinometer probe which is arranged in the inclinometer pipe and can be driven by a lifting mechanism to move up and down in the axial direction of the inclinometer pipe; and a horizontal rotating mechanism which is arranged in the outer pipe, can be combined with the inclinometer probe after being moved out of the inclinometer pipe from the inclinometer probe, and can move up and down along the outer pipe under the driving of the lifting mechanism after being combined with the inclinometer probe; and an outer pipe spiral guide groove which plays a role in guiding the horizontal rotating mechanism and enables the horizontal rotating mechanism and the inclinometer probe combined with the horizontal rotating mechanism to horizontally rotate by 180 degrees in the upward moving process of the horizontal rotating mechanism is formed in the inner wall of the outer pipe.

Description

technical field [0001] The invention relates to a device capable of horizontally rotating an inclinometer probe. It is applicable to the technical field of geotechnical engineering monitoring. Background technique [0002] In slope or landslide treatment projects, embankment foundation treatment projects, and foundation pit excavation and support projects, it is necessary to monitor the horizontal displacement of the deep part of the rock and soil mass. The most commonly used monitoring method is to use a pre-buried inclinometer. Measurement; the principle is to use the inclinometer to measure the inclination angle change of the inclinometer tube at different depths to calculate the horizontal displacement change of the inclinometer tube. This method requires two measurements to obtain a complete measurement data. In the first measurement, the high wheel of the inclinometer probe is facing inward (called "0 degree direction"). This set of readings is called A + Reading; th...

Problems solved by technology

[0003] At present, the inclinometer generally uses manual measurement to monitor the deep horizontal displacement of rock and soil. However, with the development of Internet of Things technology and the continuous improvement of safety risk prediction and early warning requirements, manual measurement can no longer meet the requirements of some projects. It is necessary to develop an automatic measuring system

[0004] The Chinese patent with the patent application number 202010636760.7 discloses "a fully automatic inclinometer and its use method", which includes a box body, a winding mechanism, a positioning mechanism, a monitoring module and an inclinometer device for a walking mechanism to realize automatic measurement. The patent does not mention the horizontal rotation function of the inclinometer probe, and the inclinometer probe cannot be rotated 180 degrees for the second measurement, only the first measurement in the direction of 0 degrees, which will affect the accuracy of the horizontal displacement calculation and does not meet the inclinometer Measuring method and principle of instrument

[0005] The Chinese patent with the authorized announcement number CN109540085B discloses "an integrated automatic inclinometer", which includes a cabinet, an automatic cable arrangement device, a steering mechanism, an inclinometer probe, a self-locking mechanism, a measurement and control module, and power supply components. The automation of the inclination process is to realize the automatic flip function of the probe through the steering mechanism, but the steering mechanism consists of a DC motor 1, an inclinometer tube, an electromagnet, a limit stopper, a driving wheel, a driven wheel and a fixed plate, and the structure is complex and power consumption
