Abstract
The utility model relates to a visual precipitation gauge which comprises a base. A transparent precipitation gauge cylinder is arranged on the base. A ruler is arranged along the direction of the cylinder body on the precipitation gauge cylinder. The ruler is adhered with a glass tube. A water outlet hole is arranged at the bottom of the precipitation gauge cylinder. The water outlet hole is connected with the bottom end of the glass tube through a rubber tube. According to the visual precipitation gauge, by using a communicating principle, the precipitation can be observed at any time; the precipitation of different time periods can be measured at any time according to records; the measurement data are accurate, convenient and timely; and the visual precipitation gauge is particularly suitable for a small observatory of a school to use.
Description
Technical field
The utility model relates to a kind of visual rain detecting device experimental teaching material.
Background technology
The udometer that the slight observatory of existing school uses is mainly first to connect rainwater by large funnel, then allows water flow in the interior right cylinder cup of udometer.Greater than cylindrical floorage, therefore, rainfall what we can not directly observe, but adopt first with the water in the right cylinder cup, first measure volume due to large funnel floorage suitable for reading, then divided by what of the upper open area amount of praying for rain in funnel.When using existing udometer, the rain stopping times such as general need just measure, and can not measure in the process of raining.The deficiency that existing udometer exists is that measurement data is not accurate enough, measuring process is inconvenient, can not in time obtains measurement result.
Summary of the invention
The purpose of this utility model is that a kind of visual rain detecting device easy to use will be provided, technical problem to be solved in the utility model is to realize by following technical scheme, visual rain detecting device, be characterized in: comprise base, base is provided with transparent amount rain cylinder, is provided with scale along the cylindrical shell direction on amount rain cylinder, is bonded with a glass tube on scale, the bottom of amount rain cylinder is provided with apopore, and apopore joins by the bottom of proofed sleeve and glass tube.
Before measurement, calculate the upper open area of output rain cylinder, determine the starting altitude of glass tube middle water level; When raining, within the unit interval, read the height of glass tube middle water level, by calculating, can record the amount of rainfall in the unit interval.
Visual udometer utilizes law of connected vessels can observe at any time what of rainfall, also can according to record, measure at any time the rainfall of different time sections.The data of its measurement are accurate, convenient, timely, so the little observatory that visual udometer especially is fit to school uses.
Description of drawings
Fig. 1 is the structural representation of visual rain detecting device.
