Traceable tipping bucket rain gauge and measuring method thereof

Abstract

The invention discloses a traceable tipping bucket rain gauge comprising a rain bearer; a tipping bucket is arranged in the rain bearer; a rain collector funnel, a converge funnel, a water storage bottle and a controller are arranged in the rain bearer; the rain collector funnel is arranged above the tipping bucket; the converge funnel is arranged below the tipping bucket, and connected with the water storage bottle below the converge funnel via a water guide tube; a three-way electric valve is arranged on the water guide tube; a drain pipe is arranged below the three-way electric valve; a rain sensing dry reed pipe is arranged on the funnel neck of the rain collector funnel; a magnetic steel is arranged on the tipping bucket; a fullness dry reed pipe is arranged on the bottle neck of thewater storage bottle; a magnetic floater is arranged in the water storage bottle so as to sense the bottle fullness state; the controller is respectively connected with the rain sensing dry reed pipe,the fullness dry reed pipe and the three-way electric valve; the three-way electric valve and the controller are powered by a battery; in addition, the invention also discloses a measuring method ofthe gauge; the traceable tipping bucket rain gauge is simple in structure, low in making cost, low in fault rate, and strong in versatility; the measuring method is high in measuring precision and true and reliable in measuring result.

Description

technical field [0001] The invention belongs to the technical field of hydrological and meteorological measuring instruments, and in particular relates to a traceable tipping bucket rain gauge and a measuring method thereof. Background technique [0002] Atmospheric precipitation measurement is an important part of the earth's water cycle detection, an important part of water resource utilization, and an important influencing factor in 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 symmetrical tipping bucket. When the amount of water accumulated in the tipping bucket reaches a certain value, which is equivalent to 0.1 mm of precipitation, the tipping bucket is tipped over, and a small pi...

Problems solved by technology

If the rainfall intensity is very strong, the tipping bucket will overturn and stall, which will lead to errors in rainfall measurement

[0005] At present, there are often inconsistencies in the rainfall results measured by the hydrological department and the meteorological department in my country. In 2016, a rainfall in Huanggang, Hubei, the hydrological department measured 650mm, while the meteorological department measured 850mm. The difference is so large that it is beyond imagination. The amount of water poured out by the tipping bucket rain gauge is discarded, and the actual precipitation cannot be investigated afterwards

[0006] At the same time, due to the implementation of automatic rainfall observation, tipping bucket rain gauges are widely used. In order to improve the accuracy of rainfall measurement, we must try to find out the reason for the questionable measurement results. It is necessary to save the amount of water poured out by the tipping bucket.
