Embodiment 1

[0031] Embodiment 1: A serial serial segment deformation monitoring sensor device (SerializedDeformationDataCollector 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 installatio...

Embodiment 2

[0038] Embodiment two: see Figure 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

The invention provides a tandem type sequence segment deformation monitoring sensing device. A plurality of unit joints are connected through universal joints and form a detection bar which can be bended at will; MEMS sensors and power supplies are arranged on all the unit joints or part of unit joints; the MEMS sensors can monitoring the acceleration and measuring the angle; each unit joint is a polygonal prism; the cross section of the polygonal prism is polygonal, and is provided with a center hole; one of the side surfaces of the polygonal prism is provided with a mounting groove; each universal joint comprises a axle tube which is arranged at the front end of each unit joint; a universal joint jaw is arranged at the front end of the axle tube; two universal joints are vertically hinged with a square slide block; a threading hole is formed in the center of the square slide block along the axial direction, and is used for assembling a signal line or a power line; the circumferential side wall of each axle tube of each universal joint is provided with a plurality of limiting holes; each limiting hole is coordinatively provided with a limiting pin; and the limiting pin is used for limits the bending angle of the two axle tubes. The tandem type sequence segment deformation monitoring sensing device can be assembled in a drill hole or an embedded structure, and can accurately monitor any geological movement and changes.

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...
