Embodiment Construction

[0007] When testing the rain gauge on site, place the water-filled chassis on the rain gauge outlet, remove the front cover and connect the corresponding water pipes as required. The 10mm and 30mm two sets of control circuit combinations on the front control panel in the operation box ( figure 2 2 and 3) can complete the rain gauge detection task. Generally, each rain gauge should be measured three times, the first time is 10mm rainfall and light rain 0.5mm / min rain intensity, the second time is 30mm rainfall and moderate rain 2.0mm / min rain intensity, the third time is 30mm rainfall and heavy rain 4.0mm / min Rain intensity. Each test result must meet the national standard requirements of the maximum error ≤ ± 4% to be considered qualified. Take the first time as an example to illustrate the specific implementation as follows: first select the 10mm control circuit combination ( figure 2 2) Make sure that the rain intensity displayed on the LCD screen is 0.5mm / min, and the...

Abstract

A portable rain gauge calibration system is an automatic detecting instrument, which can be used for detecting the rain gauge on the spot at an outdoor mounting site. The complete machine of the portable rain gauge calibration system is an aluminum-wrapped instrument box, and can be carried by hands of a single person; two lithium battery packs are arranged inside the box for power supply; two kinds of standard simulated rainfall, namely, 10 mm (314 ml) and 30 mm (942 ml) are provided; five kinds of standard simulated raininess, namely, drizzle: 0.5 mm/min, moderate rain: 1.0 mm/min or 2.0 mm/min, and heavy rain: 4.0 mm/min or 6.0 mm/min, can be provided; the portable rain gauge calibration system is equipped with a self-contained water container, an injection pump, a charging pump and a drainage (metering) pump, and has functions of automatic water injection, automatic water charging, and automatic drainage detection. When the rain gauge is detected on site, the detection task can be fulfilled only through placing the machine box on a rain receiving mouth of the rain gauge and operating relative control switches on a control panel.

Description

technical field [0001] The invention belongs to the field of automatic detection instruments, and in particular relates to a portable rain gauge verification system suitable for on-the-spot detection of rain gauges installed outdoors. Background technique [0002] Rainfall in the sky is the most common weather phenomenon in nature. It is closely related to the national economy and people's livelihood. Floods and droughts are caused by more rain and less rain. Therefore, rainfall is one of the important measurement items in meteorology, hydrology, water conservancy, military and other fields. Timely and accurate rainfall measurement is its basic requirement. At present, rainfall measurement is accomplished by using various types of rain gauges, the most important of which is the tipping bucket rain gauge. Tens of thousands of rain gauges have been deployed in meteorology, hydrology, water conservancy, military and other fields across the country to monitor rainfall. The per...
