Magnetostrictive scale for measuring water level of open channel

Abstract

The invention relates to the field of water level measurement, in particular to a magnetostrictive telescopic scale for measuring the water level of an open channel. The magnetostrictive telescopic scale for measuring the water level of the open channel comprises an electronic bin, and a first measuring rod is fixedly mounted at the bottom of the electronic bin. When the magnetostrictive scale for measuring the water level of the open channel is used, the sliding device is controlled through the controller to achieve stretching of the second measuring rod and the first measuring rod, then the magnetostrictive scale is used for meeting the requirements of open channels with different depths, meanwhile, winding or unwinding operation of a waveguide wire is achieved through the take-up mechanism, and the measurement accuracy is improved. Then the device is installed at an installable position, so that the device is fixed, the detection and installation requirements of the device for different canal depths are improved, and the adaptability of the device is improved; the first measuring rod and the second measuring rod are sealed through the water lubricated bearing installed on the second measuring rod, and the waterproof performance between the first measuring rod and the second measuring rod is achieved.

Description

technical field [0001] The invention relates to the field of water level measurement, in particular to a magnetostrictive water gauge used for open channel water level measurement. Background technique [0002] When measuring the water level of an open channel, a magnetostrictive water gauge needs to be used. The magnetostrictive water gauge can be used for water level measurement in the fields of agricultural irrigation channels, small river water levels, section water levels, urban flood control, and open channel flow. [0003] The existing magnetostrictive water gauge consists of four parts: a sensor probe, a signal processing unit, a liquid level float, and a limit snap ring. The top of the sensor probe is installed with an electronic compartment for controlling and monitoring the device. The sensor In the existing device, the probe is basically a whole measuring rod, which contains various components for detecting the water level, which can detect the water level of a c...

[0003] The existing magnetostrictive water gauge consists of four parts: sensor probe, signal processing unit, liquid level float, limit snap ring, wherein the top of the sensor probe is equipped with an electronic warehouse for controlling and monitoring the device, and the sensor In the existing devices, the probe is basically a whole measuring rod, which contains various components for detecting the water level, and can detect the water level at a certain depth, but for some small open channels or deep open channels It is said that it is impossible to measure the overall depth of the open channel, either the water gauge is too long, or the water gauge is too short, so the water gauge can only be installed at a fixed position on another side, which cannot meet different scenarios needs
