Angle sensing device for wireless drift indicator

Abstract

The invention discloses an angle sensing device for a wireless drift indicator. An upper wheel shaft assembly (A) is disposed right above a lower wheel shaft assembly (B). Both the upper wheel shaft assembly and the lower wheel shaft assembly are of the same structure. A sleeve (7) is arranged between the upper wheel shaft assembly (A) and the lower wheel shaft assembly (B) and in the structure of a straight cylinder with two ends opened. The end opening of the sleeve (7) enables an end head of a corresponding wheel shaft (1) to be sleeved. A power supply (8) is arranged in the sleeve (7). A gauge frame stand (9) is fixedly arranged on the power supply (8). A gauge frame (10) is supported on the gauge frame stand (9). A sensor (11) and an integrated circuit board (12) are arranged on the gauge frame (10).The angle sensing device for the wireless drift indicator has following beneficial effects: the angle sensing device is few in components, simple and compact in structure, small in size and convenient in assembly; lateral displacement of a landslide area and excavation soil of a deep hole can be accurately and effectively monitored; compared with the prior art, measurement cost is decreased, operation is performed more easily and the angle sensing device is more conveniently carried; and the angle sensing device is characterized by being intelligentized and is featured by being small in error, high in adjustable accuracy and fine in reliability.

Description

technical field [0001] The invention relates to the field of engineering measurement, especially to the field of space physics and geophysics, especially to monitoring the lateral displacement of landslide areas and excavated soil in deep caves, in particular to a wireless inclinometer angle sensor. Background technique [0002] The inclinometer is an in-situ detection instrument for measuring the lateral displacement of a borehole. It can be used in in-situ detection of geotechnical engineering in transportation, metallurgy, coal, water conservancy and hydropower departments, and urban construction departments, especially in slopes, It has irreplaceable superiority and practicability in the depth and lateral displacement detection of foundations, earth-rock dams and underground caverns. At present, most of the inclinometers on the market use multi-core cables to connect with the inclinometer probe. On the one hand, this connection plays the role of data communication, and o...

Problems solved by technology

At present, most of the inclinometers on the market use multi-core cables to connect with the inclinometer probe. On the one hand, this connection plays the role of data communication, and on the other hand, it plays the role of supporting connection. When measuring and using, multi-core cables will break, which will increase the cost of testing

In addition, multi-core cables are bulky and increase in weight as the depth of measurement increases, making handling even more inconvenient
