Embodiment 1

[0032] Embodiment 1: The first serialized multi-dimensional deformation data collection device (Serialized Deformation DataCollector or SDDC), see figure 1 , multiple short joints 1 are connected by universal joints 2 to form a test strip that can be bent arbitrarily, and the short joints 1 can use PVC short pipes or pipe fittings made of other materials, or special solid rods. A flexible outer sleeve 5 is sheathed on the outer side of the arbitrary curved test strip. And it is waterproof and airtight.

[0033] see image 3, embed bidirectional MEMS sensors 8 and power sources in all short joints 1 or part of short joints 1, and the signal lines of each bidirectional MEMS sensor 8 are collected in the cable 6 and then connected to the wireless transmission device. MEMS (Microelectro Mechanical Systems) is a new type of sensor manufactured using microelectronics and micromachining technology. Compared with traditional sensors, it has the characteristics of small size, light ...

Embodiment 2

[0040] Embodiment 2: The second serialized multi-dimensional deformation data acquisition device. On the basis of Embodiment 1, the rotating parts are improved, such as Figure 5 As shown, the rotating part is provided with a telescopic slot 9 at the end of the pup joint assembly 1a, and a slider 10 is provided at the end of the pup joint assembly 2 1b. A positioning groove 12 is arranged at the center of the inner wall of the telescopic groove 9 , and a positioning ring 13 is arranged on the outer wall of the slider 10 , and the positioning ring 13 cooperates with the positioning groove 12 for positioning. Under normal circumstances, it can be ensured that puppet assembly one 1a and puppet assembly two 1b are neither stretched nor compressed. The flexible outer sleeve 5 is sealed and fixed on the surface of the pup joint at the position of the rotating part.

Embodiment 3

[0041] Embodiment 3: The third serialized multi-dimensional deformation data acquisition device, on the basis of Embodiment 1, improves the positioning mechanism 4 and designs it as a movable positioning mechanism 4 . Such as Figure 7 and Figure 8 As shown, the fixed bracket 24 is set on the outer side of the flexible outer sleeve 5, and the positioning mechanism 4 is provided with a guide groove inside the fixed bracket 24. A toothed positioning fork 4c is matched and installed in the guide groove, and a rack 19 is provided on its side. , and a ring gear 25 is installed in the center of the pup joint assembly 1a or pup joint assembly 2 1b, the ring gear 25 is engaged with the rack 19 for transmission, and the ring gear 25 is installed on the motor shaft.

[0042] In addition, a supporting sleeve 22 is fitted on the outer side of the tooth type positioning fork 4c. After the formation is drilled, the detection strip is inserted into the drilled hole, and each tooth type po...

Abstract

The invention discloses a serialized multidimensional deformation data collection device. An outer side of one detection strip which can be bent freely is provided with a waterproof layer, and an inner side of the detection strip is provided with MEMS sensors and a power supply, wherein each MEMS sensor has functions of acceleration monitoring and bidirectional turning angle measurement. Signal lines of all MEMS sensors are gathered behind a cable, and then are connected with wireless transmission equipment. The device can be assembled in a drill hole or an embedded structure, and achieves the precise monitoring of any geological movement change. The device can achieve the precise monitoring of geological changes at different elevations, and enables the geological changes to be changed into a visual state or a monitoring state through the position change of the plurality of sensors at different positions and the angle changes among adjacent position sensors, so as to determine the change degree of a site. The device is compact in structure, is high in detection precision, and is good in effect.

Description

technical field [0001] The invention relates to the technical field of surface deformation monitoring of mountains or engineering slopes, in particular to a serialized multi-dimensional deformation data acquisition 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 present, most equ...
