Fully automatic evaporation overflow measuring device

Abstract

The invention relates to a fully automatic evaporation overflow measuring device and belongs to the meteorology and water conservancy technology field. The fully automatic evaporation overflow measuring device comprises an evaporating dish, a water filling barrel, and a measuring barrel connecting the evaporating dish through a pipeline. The measuring barrel has two pairs of water level control switches, wherein an open overflow switch and a closed overflow switch control a drain solenoid valve, and an open water filling switch and a closed water filling switch control a water filling solenoidvalve. A magnetostrictive water level is placed in the measuring barrel to measure a real-time water level in the evaporating dish, and an electromagnetic flowmeter is connected to a right side pipeline of the measuring barrel so as to measure water filling and an overflow flow. A right side of the electromagnetic flowmeter is divided into a water filling pipe and an overflow pipe which are provided with a water filling solenoid valve and the drain solenoid valve, and the measuring barrel is close to a peripheral concrete wall of an evaporation pool. In the invention, fully automatic water filling and draining can be realized, manual operation can be replaced and data is stored automatically in real time.

Description

technical field [0001] The invention relates to a fully automatic evaporation overflow measuring device, which belongs to the technical field of meteorology and water conservancy. Background technique [0002] Evaporation measurement is the focus of water conservancy and meteorological departments. Evaporation plays an important role in the calculation and utilization of water resource balance and water cycle. The previous automatic evaporation measurement devices have shortcomings, such as the water level gauge of some automatic devices placed in the evaporation pan , the impact on the evaporation water surface, the water level measurement device designed by some automatic devices is too far away, resulting in inaccurate water level measurement results, when replenishing water through the pump, it will have a fluctuating effect on the evaporation water surface, and the overflow cannot be accurately and timely measured during rainfall . As far as practicality is concerned, ...
