Problems solved by technology

However, although the traditional length meter has high precision, it generally has a small range and cannot be used for the overall profile measurement of large-sized heliostats
In addition, although some types of length gauges use magnetic scales or grating scales as displacement sensors,

Abstract

The invention proposes a high-precision self-resetting probe-type displacement measurement device and a measurement method. The measurement device comprises a bottom part support unit, a linear motion unit, a linear drive unit and a top part connection unit. The linear motion unit and the linear drive unit are mounted between the bottom part support unit and the top part connection unit in parallel and opposite. The bottom part support unit and the top part connection unit are arranged in parallel. The linear drive unit and the linear motion unit are connected to control the probe in the linear motion unit to vertically move upwards and downwards so as to realize the automatic measurement and self-resetting. The linear motion unit further comprises a displacement sensor to measure the displacement amount of the probe in the vertical direction. According the method, the face-to-face working manner of the linear motion unit and the linear drive unit is utilized for the contact type measurement. With the method, high-precision self-resetting automatic measurement function can be realized. The measurement method is simple and convenient, ensures relatively high stability and reliability, shortens the detection time, increases the measurement efficiency and guarantees the measurement accuracy.

Description

Technical field [0001] The invention belongs to the technical field of profile measurement, and specifically relates to a high-precision self-resetting probe type displacement measuring device and a measuring method. Background technique [0002] Tower-type solar thermal power generation technology is a new energy utilization technology, which has been rapidly developed in my country in recent years and has been gradually commercialized. In the tower solar thermal power generation system, the heliostat is the key concentrating device for concentrating solar energy. The surface shape accuracy of the heliostat installation has an important influence on the concentrating efficiency and directly affects the power generation efficiency of the solar thermal power station. Therefore, it is necessary to accurately detect the overall profile error of the heliostat. Heliostats are generally large in size and require specific testing equipment to test their profile. The length gauge is a ...
