Embodiment Construction

[0016] The present invention will be further described below in conjunction with accompanying drawings and examples.

[0017] figure 1 Shown is an example of the surface irrigation water flow movement measuring instrument of the present invention, and the measuring instrument includes a cylinder body 1, a power supply 7, a data acquisition sensor and a data processing system. The cylinder body 1 is a cylindrical cavity, and the cylindrical shape can make the water flow move smoothly. A circle of evenly spaced water inlet holes and water outlet holes 2 is opened on the lower part of the cylindrical cylinder, and these water inlet holes and water outlet holes 2 are rectangular grid through holes. In order to facilitate battery replacement, maintenance and overhaul, the cylinder 1 in the present invention is divided into three sections connected by cavities, the circuit board 3 in the data acquisition sensor is vertically placed at the bottom of the cylinder, and the power suppl...

Abstract

The present invention relates to a surface irrigation water flow movement measuring instrument. The interior of the cylinder body is equipped with power supply, data acquisition sensor and data processing system. Its sensing portion is contact sensor, on the circuit board several contact points are set, and a part of them can be used as an electrode, and the lower portion of cylinder body is equipped with water inlet and water outlet, and when the water is flowed into said cylinder body, the water and all the contact points are formed into the loop to give out electric signal, said signal canbe collected by data acquisition device, and fed into data processing system, coded, stored and processed, and can be displayed on the screen. It can be used for monitoring surface irrigation water flow movement.

Description

technical field [0001] The invention relates to an instrument for automatically measuring water flow movement parameters in the field of water conservancy irrigation. Background technique [0002] In surface irrigation, in order to understand the process of rising, maintaining, and decreasing surface water level and the required time when the water spreads, it is necessary to measure the change of the water level and the corresponding time. The existing measurement method is manual measurement and manual recording, which requires a special person to carry out, occupies a labor force, is time-consuming and labor-intensive, and the data is judged by humans with a certain degree of subjectivity. Contents of the invention [0003] In order to overcome the existing deficiency that the data required for surface irrigation cannot be automatically collected and processed, the present invention provides a surface irrigation water flow movement measuring instrument, which can automa...
