A cableless inclinometer with automatic lifting and automatic measurement

Abstract

The invention discloses an automatic-lifting and automatic-measuring cableless inclinometer. The cableless inclinometer comprises a power device, a driving device, an inclination detecting device, a signal transmission device, a rescue device and an inclination detecting tube. The inclination detecting tube is placed in the deep well of an element to be detected of an underground building structure, the inclinometer is placed in the inclination detecting tube and moves downwardly to the bottom of the inclination detecting tube, the inclination detecting device starts to implement measurement work when the inclinometer automatically ascends, and the measurement work automatically ends when the inclinometer ascends to the ground. When the inclination detecting device is embedded in the inclinometer, the rescue device is used to pull out the inclination detecting device of the inclination detecting tube. The automatic-lifting and automatic-measuring cableless inclinometer has the advantages of no cables or manual control during use, high automation degree, portability, simple structure and high practicality.

Description

technical field [0001] The invention belongs to the field of geological exploration surveying instruments, in particular to a cableless inclinometer with automatic lifting and automatic measurement. Background technique [0002] The inclinometer is a device used to measure the horizontal displacement of various depths inside the soil caused by engineering structures such as rock and soil slopes, building foundation pits, and underground buildings. The traditional inclinometer is composed of three parts: probe, transmission cable, and data receiver. The probe is connected to the cable and placed in the inclinometer hole. The cable is manually pulled to drive the probe to position and measure from bottom to top, and the data is received. to accept data from each location. When using the traditional method to measure the inclination, use a conventional load-bearing cable. A steel core wire is set in the center of the cable as the load-bearing core. The cable is equipped with a...

Problems solved by technology

When using the traditional method to measure the inclination, use a conventional load-bearing cable. A steel core wire is set in the center of the cable as the load-bearing core. The cable is equipped with a copper wire as the conductive and signal-transmitting core wire. The diameter and quality of the cable are large, and the cable required for inclinometer measurement is very long. Manually pulling the cable will cause serious twisting, resulting in damage to the cable, resulting in the failure of the inclinometer work; at the same time, data acquisition, Recording and storage rely on manual work, low work efficiency, and no automatic intelligence

[0003] Chinese application number CN201010248659.0 discloses a method and equipment for automatically collecting inclinometer data, including an automatic data collection part and a storage and receiving part. It is characterized in that a micro switch is installed inside the measuring probe, and a magnetic ring is fixed on the outer wall of the new inclinometer tube. , when the measuring probe of the inclinometer is carried out in the inclinometer tube, the micro switch is automatically opened and closed under the magnetic field of the magnetic ring on the outer wall of the inclinometer tube to realize the functions of automatic collection, recording and storage of data. The data receiver is equipped with The bluetooth module is connected with the handheld computer PDA to realize wireless data transmission, which overcomes the shortcomings of traditional inclinometers that require manual measurement and recording, time-consuming and labor-intensive, and low work efficiency

When this device is used, it still needs to use a long cable, which is inconvenient and flexible to use, and it will also cause damage to the cable and affect the inclinometer work.

[0004] Chinese application number CN201110134678.5 discloses a wireless point-type inclinometer, including an inclinometer main control circuit for wireless communication with a monitoring host, an SMA interface general-purpose antenna connected to the inclinometer main control circuit, and an inclinometer main control circuit. The inclinometer sensor components, the device has no external power supply and external leads, and at the same time, multiple wireless point inclinometers can be conveniently arranged into a distributed wireless inclinometer sensor network according to requirements, and only need to share a network management unit, which solves the problem of Difficult laying of power supply and communication cables, inconvenient installation, and high maintenance costs in engineering safety monitoring applications such as high slopes

In this device, the lifting activity of the inclinometer in the inclinometer hole is not explained, and the automatic lifting of the measuring device is not realized
