Abstract

PROBLEM TO BE SOLVED: To obtain a simple time rain gage apparatus which measures the amount of precipitation by shortening its measuring time. SOLUTION: A liquid measure-shaped container 1 whose upper face is opened is installed outdoors in a rainfall. After a set measuring time, the container 1 is taken up. While the container 1 is being tilted, the total amount of rainwater which is stored in the container is guided to a rainwater collecting chamber 5 which is formed on one side of the container. In this simple time rain gage apparatus, after the total amount is guided, the container is rearranged in such a way that the rainwater collecting chamber 5 becomes vertical, and the time amount of precipitation is read out on the basis of the level 9 and the time-converted precipitation graduation 6 of the rainwater collecting chamber 5.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus capable of easily measuring the intensity of hourly rainfall at home or the like.

[0002]

2. Description of the Related Art As a conventional technique, there are a falling rain gauge, a small radar rain gauge, a bucket type rain gauge apparatus, and the like, in which a specialized agency such as the Meteorological Agency determines and installs a representative observation point.

[0003]

The above-mentioned conventional rain gauge device is set up by a specialized organization such as the Japan Meteorological Agency and set up as a representative observation point, and the information is transmitted to the general public by television and radio. Recently, municipalities have been installing small rain gauges to collect and transmit information in small areas in order to understand local heavy rains. These rain gauge devices are required to have high accuracy in order to protect the safety of the general public, and must satisfy conditions such as an installation method and a standard verification model, which requires a large amount of cost for installation. The present invention can easily measure the intensity of hourly rainfall while staying at home,
It was invented to help prevent disasters as a means of self-defense at home.

[0004]

Means for Solving the Problems The present invention has the following configuration to achieve the above object. That is,
Reduced the measurement time of the hourly rainfall, the rainwater stored in the container of the open-topped basin, provided on one side of the container,
When the entire amount is guided to the rainwater collection chamber and the container is replaced vertically so that the open part of the rainwater collection chamber is at the top, the hourly rainfall is calculated based on the water level of the rainwater collection chamber and the time conversion rainfall scale displayed on the rainwater collection chamber. It is a simple time rain gauge device that reads the intensity.

[0005]

Embodiments of the present invention will be described below with reference to the drawings. In the drawings, FIGS. 1 to 4 show a method of measuring hourly rainfall using a simple hourly rainfall measuring apparatus according to the present invention. First, as shown in FIG.
This is a structure in which a bottom plate 3 is attached to about 5 cm of a straight wall 2 having a square shape in plan view of 2 cm. Inside the container 1 is a straight wall 2 and a bottom plate 3 on one side.
, A triangular rainwater collecting chamber 5 made of a transparent plastic plate 4 is provided. One end of the rainwater collecting chamber 5 is open, and the other end is closed by the straight wall 2 of the container 1. In addition, a time conversion rain scale 6 is displayed on the plastic plate 4.

Next, FIG. 2 shows that when the container 1 is installed outdoors during rainfall, the rainfall 7 is stored as rainwater 8 in the container 1 by integrating the plane integral of the container 1.

As shown in FIG. 3, after a certain measuring time, the container 1 in which the rainwater 8 is stored is picked up, and while the stored rainwater 8 is tilted to the front, back, left and right so as not to spill from the container 1, the rainwater collecting chamber 5 To the whole quantity.

Next, FIG. 4 shows that after the entire amount of the stored rainwater 8 is led to the rainwater collecting chamber 5, the container 1 is vertically replaced so that the opening of the rainwater collecting chamber 5 is upward. . At this time, the time rainfall is read from the water level 9 position of the rainwater collecting chamber 5 and the time-converted rainfall scale 6 displayed on the plastic plate 4 of the rainwater collecting chamber 5.

As is apparent from the above description, the present invention can easily measure the intensity of hourly rainfall by shortening the time.
Further, when a heavy rain warning or a heavy rain warning is issued, the measuring container is lightweight and small, so that even a general household can grasp the amount of hourly rainfall and prevent a disaster from occurring.

Claims (2)

[Claims] A container having an open top surface is installed outdoors during rainfall. After a certain measurement time, the container is picked up, and while the container is tilted, the entire amount of rainwater stored in the container is guided to a rainwater collecting chamber provided on one side of the container. Rainwater collecting room
The rainwater is divided into triangular shapes by a transparent plastic plate, and the guided rainwater has a structure where the water level can be viewed directly by replacing the container vertically so that the open part of the rainwater collecting chamber is at the top.
In addition, a time-converted rainfall scale is displayed on a partition plastic plate of the rainwater collecting chamber, and a water level position guided to the rainwater collecting chamber is indicated as a time-converted rainfall. 2. The structure of the rainwater collecting chamber provided in the container may be a structure other than a triangular shape, depending on the intensity of hourly rainfall.
