Unpowered rain sample quantitative fraction collector

Abstract

The invention relates to an unpowered rain sample quantitative fraction collector. The collector comprises a plurality of rain sample collection funnels which are arranged on a box body cover plate and a rain sample quantitative fraction collection part, wherein the rain sample quantitative fraction collection part is arranged in a box body and comprises a plurality of balancing plates; a vertical balance pointer is arranged on the bisected center line of each balancing plate; the two sides of the bisected center line are respectively provided with a supporting shaft; the balancing plate can rotate around the supporting shaft; a balance indicating dial is fixed on a supporting shaft support frame; the two ends of each balancing plate are respectively provided with a balancing nut; the two end faces of each balancing plate are provided with identical positioning collars; a balancing bottle and a rain collection bottle are respectively arranged in the two collars; the rain collection bottles are respectively positioned below the rain sample collection funnels; the rain sample collection funnels are freely communicated with the rain collection bottles through latex tubes; a base plate which can freely rotate is hinged on a bottom plate under each balancing bottle; and the vertically lifting height of the base plate is just equal to the distance between the balancing plate and the bottom plate when the balancing plate is balanced. The unpowered rain sample quantitative fraction collector is simple to manufacture and essentially realizes the simplification, quantification, fraction and standardization of rain sample collection.

Description

technical field [0001] The invention relates to a rain sample collector, in particular to a non-powered rain sample quantitative segment collector. Background technique [0002] With the aggravation of air pollution, the environmental problems caused by dry and wet deposition have attracted more and more attention. Wet deposition depends not only on the concentration of pollutants in the atmosphere, but also on the intensity and size of rainfall. In order to better study the environmental pollution of rainfall in a certain area, it is particularly important to collect rainfall quantitatively and segmentally. However, there are few reports on the technology of quantitatively segmented rainfall collection, which affects the development of rainwater quantification. , segmented, and standardized research. Contents of the invention [0003] The purpose of the present invention is to provide a non-powered rain sample quantitative and segmental collector to realize the simplifi...
