Abstract
Description
Technical Field
[0001] This utility model belongs to the field of rain gauge technology, specifically relating to a rain gauge for meteorological observation. Background Technology
[0002] A rain gauge is an instrument used to measure the total amount of liquid and solid precipitation over a period of time. It is typically a cylinder with a diameter of 20 centimeters, and the cylinder must be made of rigid material to maintain the shape and area of the opening. To prevent rainwater from splashing in, the opening is shaped like a knife edge, straight on the inside and slanted on the outside. Rain gauges come in two types: with and without a funnel. A water storage bottle is inside the cylinder. During the snowy season, the water storage bottle is removed, and the cylinder opening without a funnel is attached, allowing snowflakes to be collected directly at the bottom of the rain gauge.
[0003] However, existing rain gauges are often placed directly on the ground, which means they are not always perfectly perpendicular to the ground, leading to measurement errors and inconvenience during use. Furthermore, existing rain gauges often lack the function of filtering rainwater, causing debris to easily clog the funnel opening, further complicating their use. Therefore, there is an urgent need for a rain gauge for meteorological observation to solve these problems. Utility Model Content
[0004] In order to overcome the above-mentioned technical problems, the purpose of this utility model is to provide a rain gauge for meteorological observation, so as to solve the problems mentioned in the background art, that existing rain gauges are often placed directly on the ground, which can easily cause measurement errors, and that existing rain gauges often do not have the function of filtering rainwater, which can easily cause debris to clog the funnel opening.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a rain gauge for meteorological observation, comprising an outer sleeve, a water storage bottle, a first fixing frame, a second fixing frame, and a support structure. A limiting ring is fixedly connected to the bottom of the inner wall of the outer sleeve, and the limiting ring is engaged with the bottom of the water storage bottle. The top of the outer sleeve is engaged with the first fixing frame, and the top of the first fixing frame is engaged with the second fixing frame. The support structure includes a base, and three ball valves are fixedly connected to the top of the base. Threaded rods are fixedly connected to the top of the ball valves. All three threaded rods are threadedly connected to a support plate. A bracket is fixedly connected to the top of the support plate, and a level is fixedly connected to the front and right ends of the top of the support plate.
[0006] Preferably, the top of both the outer sleeve and the first fixing frame is provided with a raised ring, and the bottom of both the first fixing frame and the second fixing frame is provided with a corresponding groove.
