Abstract

The invention discloses a displacement type lysimeter. The displacement type lysimeter comprises a measuring device, a data processing unit and a terminal display unit which are sequentially connected, wherein the measuring device comprises a bracket and a steel tank; a group of upper support frame and lower support frame is symmetrically arranged on two side edges of the bracket respectively; a pulley block is arranged on the upper support frame and the lower support frame respectively; a steel wire rope is arranged between the pulley blocks; a clamping plate is fixed on the steel wire rope; the clamping plate is connected with a counterweight rod; and a counterweight block and a displacement sensor are arranged on the counterweight rod. The displacement type lysimeter of the invention has a simple structure and low manufacturing cost, is convenient to use, can monitor slight change of water evaporation and seepage of a monitored soil mass along with time, and corresponding associated parameters such as temperature, air humidity, illumination, rainfall and the like, quickly analyzes the measured data in real time, realizes high speed and accuracy of data acquisition, enhances stability and reliability, greatly improves the working efficiency and reduces the labour intensity.

Description

technical field [0001] The invention relates to an instrument for farmland hydrological research, in particular to a displacement lysimeter. Background technique [0002] At present, the lysimeter is a standard instrument for determining the evaporation of farmland. It is a large-scale instrument set up in the field or indoors. It is filled with soil, and the change in the weight of the container is measured regularly by weighing, and then calculated. evapotranspiration. Most of the lysimeters currently in use do not have the functions of online analysis, remote data transmission, etc., and cannot achieve high-speed and accurate data. Therefore, this kind of instrument brings a large workload and low work efficiency. Contents of the invention [0003] Purpose of the invention: In view of the deficiencies in the prior art, the purpose of the invention is to provide a displacement lysimeter, so that it has the functions of convenient use, accurate measurement, online analys...
