Full-automatic tipping-bucket rain gauge titrator

Abstract

The invention discloses a full-automatic tipping-bucket rain gauge titrator which is characterized in that the titrator comprises a bottom plate (18) and a shell (19) covering the bottom plate (18); a water storage tank (1) is arranged inside the shell (19); the water outlet of the water storage tank (1) is communicated with the top bottle shoulder of a main standard bottle (2) through a water feeding ball valve (13); an upper annular boss is arranged on the bottom end inside the upper bottle mouth of the main standard bottle (2); an overflow floater (5) is arranged on the upper annular boss; and a main bottle stopper (7) is arranged on the top end inside the upper bottle mouth of the main standard bottle (2). The full-automatic tipping-bucket rain gauge titrator provided by the invention employs the microelectronics measurement and control technology, has the functions of automatic filling and automatic detection under management and control of a controller, and can be started through one button. The whole process of filling through a standard volumetric flask, arbitrary setting of high and low rainfall intensity and error counting is completed automatically. The full-automatic tipping-bucket rain gauge titrator has the characteristics of being portable and practical, time-saving and labor-saving, accurate in calibration, intelligent and efficient, and the like.

Description

technical field [0001] The invention relates to a fully automatic tipping bucket rain gauge titrator, in particular to a fully automatic tipping bucket rain gauge titrator for accurately detecting the measurement error of the tipping bucket rain gauge so as to adjust the size of the tipping bucket and accurately measure rainfall, belonging to The technical field of hydrological and meteorological measuring instruments. Background technique [0002] Atmospheric precipitation measurement is an important link in the monitoring of the earth's water cycle, an important part of water resource utilization, and an important factor affecting many aspects such as climate change, geological disasters, flood disaster warning, and environmental assessment. Scholars in the industry have sought various methods to analyze rainfall Make precise measurements. [0003] Measuring principle of the tipping bucket rain gauge: the measuring part of the tipping bucket rain gauge is mainly a symmetr...

Problems solved by technology

Therefore, it is very difficult for this method to simulate three kinds of rain intensities: small, medium and heavy.

[0008] The field tipping bucket rain gauge calibration can only use the second method: artificial water supply verification method, measure 314g of water with a 10mm standard measuring cylinder dedicated to hydrology and meteorology, and simulate the rain intensity of 0.5mm / min, 2mm / min and 4mm / min evenly From the funnel to the tipping bucket, not only the rain intensity cannot be controlled, but also the remaining water volume in the tipping bucket cannot be estimated, so the accuracy of the test cannot be guaranteed
