Overhanging sensor support

Abstract

The invention discloses an overhanging sensor support. The overhanging sensor support comprises a base part and an overhanging part used for linearly arraying sensors, wherein one end of the overhanging part is installed on the base part through a vertical pin shaft, so that the overhanging part has a freedom degree of rotating around the axis of the pin shaft. A first rope hanging part is arranged on the upper portion of the base part, and correspondingly a second rope hanging part is arranged on the upper portion of the other end of the overhanging part. The overhanging sensor support is further provided with a steel rope connected with the first rope hanging part and the second rope hanging part, and the first rope hanging part or the second rope hanging part is a movable rope hanging part of which the position can be adjusted in the connecting line direction of the first rope hanging part and the second rope hanging part. A level gauge is arranged on the upper surface of the overhanging part. The overhanging sensor support can be in an ideal level state when unfolded.

Description

Technical field [0001] The invention relates to a cantilever bracket for arranging sensors. Background technique [0002] In some applications, the use of sensors is not the use of a single sensor, but requires multiple sensors to form a specific array, so that accurate sampling can be obtained. It can be seen that the sampling accuracy is not only related to the accuracy of the sensor itself, but also related to the array. The array inevitably needs to be supported by a predetermined layout to form a support for the sensor. [0003] In some applications, the shape of the array needs to be stable. For example, it is necessary to strictly control that all sensors are located on the same plane, and the distance between the sensors remains unchanged. This requires the support to have a certain degree of stiffness, more often static stiffness. [0004] In practical applications, those skilled in the art will inevitably face such situations. For example, the sensor holder has a foldabl...

Problems solved by technology

[0006] When the sensor bracket is unfolded, it will form an overhang structure supported only by the pin shaft, or there is only one support point. Mechanically, as long as it is a movable fit, there must be a fit gap, and the overhang end will enlarge the pin shaft. Fit the gap, and the longer the bracket, the greater the sag of the overhanging end, which cannot ensure that the sensors in the linear array are on the same level

And as the service life increases, the fit clearance will gradually increase

[0007] In view of this, currently, for example, the pin axis is pre-set as a vertical axis with a certain inclination to compensate for the sagging of the overhanging end of the overhanging sensor bracket. However, this fixed structure cannot adapt to the adjustment of the fit clearance. natural variation

[0008] In addition, the pin shaft in this overhang structure is often fixed at one end, for example, it is partly fixed into the body, and partly protrudes, so that the protruding part is connected with the sensor bracket, which will inevitably further increase Influence of fit clearance on actual use
