Problems solved by technology

However, when the measuring range is large (the measuring range is greater than 2m), or even the measurement occasions where the measuring range is greater than 8m, if the above-mentioned resistive wave height sensor structure is still used, then the parallelism between the two steel pipes and the straightness of each steel pipe cannot be guaranteed. The parallelism and straightness between the two steel pipes directly affect the linearity of the wave height sensor, thereby affecting the measurement accuracy, resulting in the problem of low measurement accuracy due to the increase in the measuring range

Abstract

The invention relates to a wide-range resistive wave-height sensor, which comprises an upper tensioning frame and a lower tensioning frame. Two parallel resistance electrodes are fixedly connected between the upper tensioning frame and the lower tensioning frame. The two parallel resistance electrodes are connected with a detection circuit. The wave-height sensor is technically characterized in that the two parallel resistance electrodes are formed by an integral steel wire rope; the middle portion of the steel wire rope is hinged to the lower tensioning frame; and the two ends of the integral steel wire rope are hinged to the upper tensioning frame. Linearity and parallelism of the two resistance electrodes of the wave-height sensor can be ensured, and measuring range can reach 8-10 m.

Description

technical field [0001] The invention belongs to the technical field of port and offshore engineering physical model experiment research, and relates to a wave height sensor for real-time detection of wave height and water level height, in particular to a large-range resistive wave height sensor. Background technique [0002] In the field of port and offshore engineering experimental research technology, wave making is an essential experimental method for physical model test research. During the wave making process, wave height sensors need to be used to detect wave height in real time. [0003] For general liquid level measurement, because the liquid level changes relatively slowly and the liquid surface is flat, ultrasonic, laser, radar, resistance, capacitance, pressure, float and other liquid level gauges can meet the measurement needs. Wave height measurement is a kind of liquid level measurement. Because the liquid level changes rapidly, pressure and float measurement m...
