Embodiment Construction

[0080] First, assemble the parts according to the above assembly instructions; second, slide the position of the support slider (12) on the rod (2) according to the different diameters of the pipeline, so that its position adapts to the diameter of the pipeline; third, rotate the positioning The clip (5) makes it be stuck in the transverse groove of the bar (2), so that the position of the support slide (12) on the bar (2) is fixed; the 4th, the other seven support slides ( 12) Repeat the above operation so that the distances between the eight supporting sliders are the same (the plates are evenly arranged); fifth, move the clamping slider (3) to the nearest position from the tube wall as much as possible, and then rotate and position The clip (5) is stuck in the transverse groove of the rod (2) so that the position of the clamping slider (3) on the rod (2) is fixed; the sixth, the other seven clamping sliders (3 ) Repeat the above operation, so that the positions of the eight...

Abstract

The invention relates to a multi-parameter adjustable clamp device for an ECT sensor and belongs to the field of auxiliary detection. The clamp mainly comprises a rotating joint, a rod piece, a clamping sliding block, a flat-end screw, a locating clamping part, a bolt, a T-shaped turning piece, a hexagon nut, a pole plate pressing block, an angle locating buckle, an L-shaped supporting rod and a supporting sliding block. The multi-parameter adjustable clamp device enables each pole plate of the sensor to be in tight contact with a pipeline and be firmly fixed and be easy to assemble and disassemble; the coplanarity of each pole plate of the sensor on the circumferential plane and distribution uniformity of a pole plate array (the central angle between adjacent probes is the same) can be guaranteed; and the multi-parameter adjustable clamp device can be suitable for installing cylindrical pipelines of different diameters. The designed clamp can be used for auxiliary measurement of the capacitance of the specific ECT sensor; and the clamp has a certain universality and is flexible and convenient.

Description

technical field [0001] The invention mainly relates to a multi-parameter adjustable ECT sensor fixture device, which is mainly used for electric capacitance tomography measurement, especially for the detection and imaging of fluid and gas distribution, flow pattern, etc. in a cylindrical pipeline, and belongs to the sensor fixing device in the detection field . Background technique [0002] Computed tomography (Computed tomography) technology refers to the technology of reconstructing the internal (cross-sectional) information of an object through the data detected from the outside of the object, also called computer-aided tomography. Tomography technology has innovated the detection method of probing the internal structure of objects. When the detection method of the application is a capacitive sensor, it is called electrical capacitance tomography. During the scanning process, the electrode plate of the array capacitance tomography sensor needs to be evenly distributed o...
