Embodiment 1

[0031] Embodiment 1: A serial serial segment deformation monitoring sensor device (Serialized Deformation Data Collector or SDDC), see Figure 1-5 , a plurality of unit sections 1 are connected by a universal joint 2 to form a test strip that can be bent arbitrarily, and the main body of the unit section 1 is a triangular prism. Due to the large length range of the unit section, the longer unit section is half a meter to several meters long, and the cylindrical unit section itself is weak in bending resistance, and it is easy to affect the detection data due to its own deformation. In the present invention, the main body of the unit section is set as a triangular prism, which can obviously improve the bending resistance strength.

[0032] The triangular prism is provided with a central hole 1b, and one side of the triangular prism is provided with an installation groove 1a, the depth of the installation groove 1a is larger than the diameter of the central hole 1b; the installa...

Embodiment 2

[0038] Embodiment two: see Image 6 , the second serial serial segment deformation monitoring sensor device, on the basis of the first embodiment, the universal joint 2 is improved, and the N limit holes 2f are arranged crosswise along the axial and radial directions of the shaft tube 2a. This arrangement makes it more precise to adjust the angle of the universal joint.

Embodiment 3

[0039] Embodiment three: see Figure 7-8 , the third serial serial segment deformation monitoring sensing device, on the basis of the first embodiment, the unit section 1 is improved, the installation groove 1a in the third embodiment is larger than the opening size of the installation groove 1a in the first embodiment, The installation groove 1a is fitted with an elastic cover plate 1c, and the elastic cover plate 1c is clamped in the installation groove 1a through the tongue 1d provided at the front end. The effect of unit section 1 strength is minimized.

Abstract

A serial sequential segmental deformation monitoring sensor device, in which multiple unit sections are connected by universal joints to form a detection strip that can be bent arbitrarily, and MEMS with functions of acceleration monitoring and angle measurement are set on all unit sections or some unit sections Sensor and power supply, the unit joint is a polygonal prism with a polygonal cross section, the polygonal prism is provided with a central hole, and one side of the polygonal prism is provided with a mounting groove; the universal joint includes a shaft tube arranged at the front end of the unit joint, The front end of the shaft tube is provided with a universal joint yoke, and the two universal joint yokes are vertically hinged on a square slider, and a threading hole for assembling signal lines or power lines is arranged in the center of the square slider along the axial direction; A plurality of limit holes are arranged on the circumferential side wall of each shaft tube of the knuckle, and limit pins are matched and installed in the limit holes, and the limit pins are used to limit the bending angle of the two shaft tubes. The invention can be assembled in a borehole or an embedded structure, and can accurately monitor any geological movement change.

Description

technical field [0001] The invention relates to the technical field of surface deformation monitoring of mountain bodies or engineering slopes, in particular to a series-type sequential segmental deformation monitoring sensor device for drilling or embedding structures. Background technique [0002] Mountain slopes and landslides are common and major geological disasters, such as traffic interruptions, river blockages, reservoir accidents, building collapses, factories and mines buried, etc., resulting in huge economic losses and loss of life and property. Therefore, for landslides that are not suitable for handling or are more dangerous, monitoring their deformation dynamics and timely warning can prevent the occurrence of disasters. And for slopes that are being reinforced and treated, monitoring can also provide reliable information for construction and ensure construction safety. [0003] Surface deformation monitoring is an important part of slope monitoring. At presen...
