Description

Technical Field

[0001] The utility model relates to the technical field of inclinometers, in particular to a flexible inclinometer used for slopes. Background Art

[0002] The flexible inclinometer (also known as an array displacement meter) is a new, intelligent, 3D deformation monitoring sensor suitable for a variety of industrial applications. It is primarily used to measure displacement (deformation), angle, acceleration, vibration, and temperature in three dimensions, and is widely used in monitoring fields such as hydropower, railways, tunnels, slopes, tailings, and foundation pits.

[0003] Publication No. CN215491674U discloses a flexible inclinometer for three-dimensional displacement monitoring. This technology discloses "a flexible inclinometer for three-dimensional displacement monitoring, comprising an inclinometer tube, an array displacement sensor, and at least one clamping member disposed between the inclinometer tube and the array displacement sensor, the clamping member comprising a clamping member body, four elastic sheets evenly disposed on the clamping member body, a clamping block disposed on an outer side of the elastic sheet away from the clamping member body, the clamping block slidably mounted in a groove disposed in the inner wall of the inclinometer tube, the groove extending along the length of the inclinometer tube, and having a width greater than the width of the clamping block." The technology has the following technical advantages: "simple structure, easy installation, strong adaptability, ease of maintenance, and a wide range of applications."

[0004] The guide wheel is a key component in the flexible inclinometer, responsible for guiding the instrument to move correctly in the inclinometer casing. Since the guide wheel is installed on the inclinometer and cannot be replaced, its wear and aging over time may lead to performance degradation, thereby affecting the measurement accuracy and reliability of the inclinometer. Although the guide wheel has a certain adaptability to the pipe diameter and can adapt to inclinometer casings of different sizes within a certain range, it lacks sufficient flexibility for larger or smaller inclinometer casings.

After the probe assembly 11 and the connecting assembly 12 are inserted and installed, the tight sleeve 135 on the nut 134 is threadedly installed on the sleeve 131 and rotated to tighten, so that the tight sleeve 135 squeezes the tight head 132 and tightens it, thereby tightening the connection between the probe assembly 11 and the connecting assembly 12 to prevent the probe assembly 11 and the connecting assembly 12 from loosening after installation; and the guide assembly 14 is also fixed by the fixing assembly 13, so that the guide assembly 14 can be disassembled and assembled together when the probe assembly 11 and the connecting assembly 12 are disassembled and assembled.

[0034] Specifically, the fixing assembly 13 further includes a plurality of grooves 133 circumferentially distributed on the tight head 132 , and the tight head 132 is made of a soft rubber structure.

[0035] In this embodiment, the tight head 132 has space to shrink when being squeezed.

[0044] The working principle and usage process of the present invention are as follows: first, the fixing assembly 13 is sleeved on the probe assembly 11, and then the guide assembly 14 is sleeved and installed on the sleeve 131. When the probe assembly 11 and the connecting assembly 12 are inserted and installed, the tight sleeve 135 on the nut 134 is threadedly installed with the sleeve 131 and rotated to tighten, so that the tight sleeve 135 squeezes the tight head 132 and tightens it, thereby tightening the connection between the probe assembly 11 and the connecting assembly 12 to prevent the probe assembly 11 and the connecting assembly 12 from loosening after installation; and the guide assembly 14 is also fixed by the fixing assembly 13, so that the guide assembly 14 can be disassembled and assembled together when the probe assembly 11 and the connecting assembly 12 are disassembled and assembled; and the disassembly and assembly of the protective assembly 15 is the same as that of the guide assembly 14, and since the upper protective assembly 15 is fixed by the fixing assembly 13 at the bottom of the probe assembly 11 at the lower end, a large impact can be avoided when it contacts the ground.
