Abstract

The invention discloses a four waters transformation monitoring device which comprises a surface water monitoring part, a rainfall monitoring part, an underground water monitoring and underground water level control part and a soil water monitoring part, wherein the surface water monitoring part comprises a runoff measuring cylinder and an earth-center lysimeter measuring cylinder, a first wireless water level gauge is arranged in the runoff measuring cylinder, and the top of the runoff measuring cylinder is connected with the top of the earth-center lysimeter measuring cylinder by a water guide pipe; the rainfall monitoring part comprises a rain gauge, and a second wireless water level gauge is arranged in the rain gauge; the underground water monitoring and underground water level control part comprises a water level balancer, a Mariotte bottle and an infiltration measuring cylinder, an infiltration guide pipe is arranged in the water level balancer in a penetrating manner, the bottom of the infiltration guide pipe communicates with the top of the infiltration measuring cylinder, and a third wireless water level gauge is arranged in the infiltration measuring cylinder; and the soil water monitoring part comprises a wireless data transceiver and a user terminal, the wireless data transceiver is configured to receive data sent by the first wireless water level gauge, the second wireless water level gauge and the third wireless water level gauge and send the data to the user terminal, and the water volume in soil is obtained through calculation by the user terminal, so that full-automatic comprehensive monitoring can be realized.

Description

technical field [0001] The invention relates to the technical field of hydrological measurement, in particular to a four-water conversion monitoring device. Background technique [0002] "Four waters" refer to atmospheric water (precipitation), surface water (surface runoff water), soil water, and groundwater. The transformation of "four waters" refers to the mutual transformation between atmospheric water (precipitation), surface water, soil water, and groundwater. The development and research of the "four water" transformation experiments are of great significance for agricultural water conservation, groundwater assessment, and soil reservoir regulation. [0003] At present, domestic experimental monitoring equipment for measuring atmospheric water (precipitation), surface water (surface runoff water), soil water and groundwater mainly include siphon rain gauge, tipping bucket rain gauge, runoff measuring instrument, soil moisture monitor (TDR), Groundwater detectors and ...

Problems solved by technology

[0003] At present, domestic experimental monitoring equipment for measuring atmospheric water (precipitation), surface water (surface runoff water), soil water and groundwater mainly include siphon rain gauge, tipping bucket rain gauge, runoff measuring instrument, soil moisture monitor (TDR), Groundwater detectors and detectors, etc. These devices are advanced in technology, complete in function, and widely used, but they lack systematic and comprehensive monitoring of the mutual transformation of "four waters". In order to understand the transformation process of "four waters" more intuitively, To explore the transformation law of "four waters" and build a circulation system of surface and groundwater resources, it is necessary to study a "four waters" transformation monitoring device
