Abstract

The invention relates to a field rainwater collecting and metering device and belongs to the technical field of meteorological data measurement. The device comprises a water containing funnel, a raincollector, a supporting steel frame and a sample containing bottle; the water containing funnel is communicated with the rain collector through a flange plate I, a hinge and a flange plate II; the supporting steel frame is fixed to the surface of a field soil layer through a soft foot stand and a steel frame ring, wherein the soft foot stand is located at the lower portion of the supporting steelframe; and the water containing funnel and the rainwater collector which are communicated with each other are placed in the supporting steel frame; and the sample containing bottle is connected with the low portion of the supporting steel frame so as to collect rainwater. The field rainwater collecting and metering device is arranged at a field test point and is opened and closed as required, andtherefore, pollution and blockage are avoided, and the service life of the device is prolonged; and meanwhile, the device is simple and convenient to mount and dismount, simple to operate, enables directness and quickness in reading, has good controllability, is capable of realizing field rainfall collection and measurement with higher precision requirements, and is easy to popularize and use.

Description

technical field [0001] The invention relates to a field rainwater collection and metering device, which belongs to the technical field of meteorological data measurement. Background technique [0002] Rainfall refers to the depth of rainwater that falls on the horizontal surface (without leakage, evaporation, loss, etc.) within a certain period of time. It is the data that measures the amount of precipitation in a certain period of time in an area. Rainwater measurement devices such as rain gauges are widely used Used to measure rainfall. Rainwater metering and collecting devices are installed in the field and work when it rains, and are widely used in the fields of meteorology and hydrology. At present, related patents involving rain gauges: Rain gauges (201620982932.5) are exposed to the wild for a long time, and bird feces and particulate matter in the air are easy to pollute and block the rain gauge water inlet, thereby affecting the measurement results; an impurity-pro...
