Rotating mechanism for bidirectional dynamic pressure measuring sensor

Abstract

The invention discloses a rotating mechanism for a bidirectional dynamic pressure measurement sensor. The rotating mechanism comprises a connecting base (1), a cavity (2) and a sampling part (5), wherein the upper part of the connecting base (1) is connected with a fluid pressure sensor; the top part of the cavity (2) is fixed with the bottom part of the connecting base (1); the top part of the sampling member (5) is movably connected with the bottom part of the cavity (2), so that the sampling part (5) can rotate in the horizontal direction relative to the cavity (2); and a vertical partitionplate (3) is arranged in the cavity (2) and used for dividing the interior of the cavity (2) into two isolated parts, two guide pipes (4) are fixed to the sampling component (5) in the vertical direction, the upper end of each guide pipe (4) extends into one of the two parts of the cavity (2), and the lower ends of the guide pipes (4) are connected with fluid pressure sampling openings respectively. The rotating mechanism is simple and compact in structural form, is convenient for installation and angle adjustment, and is further convenient for static pressure, differential pressure, flow velocity, flow and other sensor applications based on the dynamic pressure measurement principle.

Problems solved by technology

[0004] The bidirectional dynamic pressure detection sensor can measure fluid pressure parameters in two directions on narrow and long pipelines such as pipelines, tunnels, mine roadways, etc. The usual sensor electrical body and detection structural components are relatively fixed, and the positive and negative bidirectional sampling port axes of the detection structural components are in line with the pipeline. The main body display window of the sensor is parallel to the two-way horizontal line of the detection structural components. In the actual application scene, some places need to be observed parallel to the pipeline, and some places need to be observed perpendicular to the pipeline or at other angles. The traditional design causes the sensor display and The relative angle of the sampling port of the detection structural components is fixed, and it is difficult to meet the needs of adjusting the angle for easy observation
