Description

Flexible inclination measuring sensor screwing clamp

Technical Field

The invention relates to the technical field of flexible inclination measuring sensors, in particular to a screwing clamp of a flexible inclination measuring sensor.

Background

The flexible inclinometry sensor is an intelligent monitoring sensor based on an MEMS (micro electro mechanical system) triaxial acceleration chip and a space attitude calculation algorithm, and is used for monitoring the deformation of a structure and soil; such as dams, tunnels, slopes, civil engineering, etc.; the continuous 2D/3D measuring array is formed by cascading a plurality of sensors;

the sensor main body part is a cascaded MEMS sensor, the MEMS sensor is packaged in a stainless steel pipe (sensing unit), and a plurality of sections of stainless steel pipes are cascaded (additional accessories) to form a complete product; the sections are connected through a hydraulic rubber tube assembly (also called as a joint), and the hydraulic rubber tube assembly is relatively flexible and can be freely deformed when being pressed by the outside, so that the spatial postures of the sections of the steel tube are driven to change, and an MEMS sensor arranged in the steel tube can sense the spatial posture change. In FIG. 1, a light color part is a stainless steel pipe section (sensing unit) and is internally provided with an MEMS sensor, a dark color part is a hydraulic rubber pipe assembly, and FIG. 2 is a structural diagram of a typical design of a flexible inclinometer sensor;

the spatial attitude solution algorithm, as described above, relies on two factors: the first is that the built-in MEMS chip of the sensing unit can resolve the change of the self space angle of each sensing unit (this is the basic application of the MEMS accelerometer, and the change of the space angle is sensed by sensing the change of the gravity acceleration on each axis component of the MEMS chip); secondly, the distance between the sensing units is needed, which is easy to understand, because the change of the space attitude or the space position is calculated through a trigonometric function, the angle change and the basic length data are certainly needed at the same time, and the length data is needed, namely the distance between the sensing units is accurate;

the largest application scene of the sensor is deep displacement measurement of a side slope, a dam and the like as described above, and the popular description is that holes are drilled on the side slope or the dam, and then the flexible inclination measuring sensor with the maximum length of more than one hundred meters is placed in the hole; for example, in a slope scene, such a deep hole is drilled, the sensor can meet an underground water layer at a high probability, and the sensor needs to be strictly waterproof, and for waterproofing, a stainless steel pipe and a joint (a hydraulic rubber pipe assembly) of a sensing unit are designed into a sealed pipe thread (such as a American standard NPT pipe thread) connection (added pipe thread sealant or a raw material tape);

as is known, the screwing size of pipe threads is very difficult to control, in actual operation, the screwing length can be influenced by the pipe thread machining precision, the amount of pipe thread sealant or raw material tape and the torque applied during screwing, the screwing length difference can even reach the level of several millimeters, and the flexible inclination measuring sensor which usually uses pipe threads (such as a tap water pipe) is not suitable for the situation, but cannot accept a flexible inclination measuring sensor with the displacement measuring precision requirement reaching the level of 0.01 mm.

In the prior art, the screwing length is generally controlled manually by measuring and the like by an assembler, and the method has low efficiency and poor consistency. Therefore, there is a need for a flexible inclinometer sensor screwing clamp that at least partially solves the problems of the prior art.
