Description
Technical Field
The invention relates to the technical field of flexible inclinometry sensors, in particular to a screwing clamp of a flexible inclinometry sensor.
Background
The flexible inclinometry sensor is an intelligent monitoring sensor based on a MEMS (micro electro mechanical system) triaxial acceleration chip and a space attitude calculation algorithm and is used for monitoring structure and soil deformation; such as dams, tunnels, slopes, civil engineering, etc.; the method comprises the steps of forming a continuous 2D/3D measuring array through cascade connection of a plurality of sections of sensors;
the sensor main body part is a cascading MEMS sensor, the MEMS sensor is packaged in a stainless steel pipe (a sensing unit), and a plurality of sections of stainless steel pipes are cascaded (externally added accessories) to form a complete product; the sections are connected through the hydraulic rubber tube assembly (also called as joint), and because the hydraulic rubber tube assembly is relatively soft and flexible, the hydraulic rubber tube assembly can deform freely when being pressed by the outside, the spatial postures of the steel tubes of the sections are driven to change, and the MEMS sensors arranged in the steel tubes can sense the spatial posture changes. The light part in FIG. 1 is a stainless steel pipe section (a sensing unit), a built-in MEMS sensor is arranged, the dark part is a hydraulic rubber pipe assembly, and FIG. 2 is a structural diagram of a typical design of a flexible inclinometry sensor;
the spatial pose calculation algorithm as described above depends on two factors: the first is that the built-in MEMS chip of the sensing unit can calculate the change of the self space angle of each sensing unit (the basic application of the MEMS accelerometer is that 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 need for a spacing between the sensing units is readily understood, since the spatial pose or spatial position change is calculated by a trigonometric function, which must be accompanied by both angular change and basic length data, which is required, i.e. the spacing between the sensing units is accurate;
the largest application scene of the sensor is that the deep displacement of a side slope, a dam and the like is measured, and popular description is that holes are punched on the side slope or the dam, and then the flexible inclinometry sensor with the maximum length exceeding hundred meters is put in; for example, in a slope scene, holes are drilled so deeply that an underground water layer is encountered with high probability, the sensor needs to be strictly waterproof, and for the waterproof, a stainless steel pipe and a joint (a hydraulic rubber pipe assembly) of the sensing unit are designed into a sealing pipe thread (such as a American standard NPT pipe thread) connection (a pipe thread sealing glue or a raw material belt is added);
as is well known, the screwing dimension of the pipe thread is very difficult to control, in practical operation, the machining precision of the pipe thread, the amount of sealant or raw material tape used for the pipe thread and the torque applied during screwing can affect the screwing length, and the difference of the screwing length can even reach the order of a plurality of millimeters, so that the situation (such as a tap water pipe) of using the pipe thread is not considered, but a flexible inclinometry sensor with the displacement measurement precision of 0.01mm is not acceptable.
The prior art is generally to manually control the screwing length by means of assembly personnel measurement and the like, which is inefficient and has poor consistency. Therefore, there is a need for a flexible inclinometry sensor snap-in fixture that at least partially addresses the problems of the prior art.
