Abstract
The invention discloses an indoor columnar soil layer specific yield automatic determination system. An iron support, a water column, a screw, a displacement sensor fixing end, and an elevation motor are respectively fixed on a pedestal. The elevation motor is connected with the screw through a coupling and a gear. A soil column is connected with the water column. An elevation platform is threadedly connected with the screw. A mobile end of the displacement sensor, and a three-way overflow complement device are fixed on the elevation platform. A PLC programmable controller and a touch screen are arranged in a chassis welded on a side of the iron support. The system provided by the invention is adopted as a teaching instrument. With the system, students can better learn the concept and influence factors of specific yield, such that student knowledge can be expanded. In scientific researches, with the system, the measuring manner is changed. A water supply device and a water overflow device are integrated, such that the system is simple and integral. With control collection designs of the control elements, automatic monitoring of two determination processes of soil body water saturation and water release can be realized. Therefore, various soil layer specific yield mechanism researches can be carried out, and application prospect is wide.
Description
technical field [0001] The invention belongs to the scope of groundwater testing technology and equipment, in particular to an automatic measuring system for indoor columnar soil water supply. Background technique [0002] The soil water supply degree μ is an important indicator of soil water release and water storage performance. When the groundwater drops per unit water head, the volume Q of water that can be released from the soil per unit volume V is called the soil water supply degree μ=Q / V, it is one of the most important parameters in the analysis and calculation of groundwater resources. Whether or not it can be objectively understood and estimated correctly is the key to the reliability of water resource estimation. The determination of hydrology and water resources is essential in the teaching and research of hydrology and water resources. At present, the traditional indoor measurement method generally adopts the method of manual measurement. A certain height of ...
