The invention relates to a dust-proof rain gauge which comprises an outer cylinder and a collection barrel fixedly connected to the outer cylinder. The collection barrel is fixed to the bottom of the outer cylinder. The outer cylinder is internally provided with a rain separating assembly which comprises an inner cylinder. An axial end of the inner cylinder corresponding to the top of the outer cylinder is connected to a gravity sleeve. The side wall of the gravity sleeve is slidingly connected to an inner cylinder inner wall. The closed end of the gravity sleeve is connected to a rain drainage pipe. The inner cylinder inner wall is also provided with a support ring which is elastically connected to the gravity sleeve. The side wall of the inner cylinder corresponding to the top of the outer cylinder is also provided with a plurality of auxiliary rain drainage ports in an array, and the inner cylinder inner wall is also correspondingly provided with a ring-shaped rain drainage groove. The side wall of the inner cylinder corresponding to the top of the outer cylinder is provided with a trumpet-shaped separation sleeve whose surface is also provided with a plurality of strip-shaped rain drainage ports. The side wall of the inner cylinder corresponding to the bottom of the outer cylinder is also provided with a trumpet-shaped flow guiding ring. The surface of the inner cylinder is provided with a plurality of rain drainage grooves in an array, and the rain drainage grooves are coaxial with the axis of the inner cylinder.
Description
technical field [0001] The invention relates to a dustproof rain gauge, which belongs to the field of meteorological equipment. Background technique [0002] Due to the development of industry and society, the pollution caused by factories and buildings has gradually increased, and during the rain, a large amount of dust and particles in the air will fall back to the ground with the rain, so most of the rain in the city now It will be mixed with a large amount of soluble or insoluble matter; the rain gauge is an instrument used by meteorologists and hydrologists to measure the amount of precipitation in a certain area over a period of time (the measurement of snowfall requires the use of a snow gauge); common There are two types: siphon type and tipping bucket type; traditional rain gauges measure rainfall by directly collecting rainwater. In the rainwater collector of the rain gauge, these soluble or insoluble substances and impurities will seriously affect the correct est...
