Abstract

The present invention provides a rain gauge, and relates to the field of precipitation metering instrument devices. The rain gauge comprises a water collection funnel, an inner funnel, a U-shaped tubemeasurement cylinder, a water level floater and a water level sensor. The U-shaped tube measurement cylinder comprises a first measurement cylinder and a second measurement cylinder, the cylinder radiuses of the first measurement cylinder and the second measurement cylinder are the same, the bottom portions of the first measurement cylinder and the second measurement cylinder communicate with each other, wherein the inner funnel is arranged at the lower portion of the water outlet of the water collection funnel, and the water outlet of the inner funnel is connected with the water inlet of thefirst measurement cylinder; the radius of the water outlet of the water collection funnel is larger than the radius of the water inlet of the first measurement cylinder; and the second measurement cylinder is internally provided with the water level floater, the water level sensor is arranged above the water level floater in the second measurement cylinder to measure the water level of the U-shaped tube measurement cylinder based on the position of the water level floater. The rain gauge improves the measurement precision of the rainfall.

Description

technical field [0001] The invention relates to the field of precipitation measuring instruments and equipment, in particular to a rain gauge. Background technique [0002] Precipitation is an important meteorological element. The observation of precipitation is of great significance to the observation of meteorology, hydrology, ocean and environment, as well as to the safety of aviation and railway traffic. The rain gauge (rainfall recorder, or rain gauge, rain gauge) is an important instrument used to measure the precipitation in a certain area over a period of time. Its measurement accuracy and wide applicability to various rain intensity conditions directly It is particularly important for rainfall observation, which is related to the accuracy and reliability of the measured data. [0003] There are many types of rain gauges, the common ones are siphon rain gauge, weighing rain gauge, tipping bucket rain gauge, etc. At present, the main form of rain gauge is tipping buc...
