Description

Technical Field

[0001] The utility model belongs to the technical field of rain gauges, in particular to a foreign matter filter for a funnel of a tipping bucket rain gauge. Background Art

[0002] The tipping bucket rain gauge is an important hydrological measurement tool widely used in meteorology, agriculture, environmental protection and other fields. Its core principle is to measure rainfall by the number of times the tipping bucket flips. The instrument collects rainwater through a rain collector, and then the rainwater flows into the tipping bucket. When the water volume in the tipping bucket reaches a certain threshold, the tipping bucket flips to achieve cumulative recording of rainfall.

[0003] However, in actual applications, rainwater often carries various impurities during its fall, including but not limited to dust, leaf fragments, insects and other tiny particles. If these foreign objects are not effectively filtered and directly enter the interior of the tipping bucket rain gauge, especially the tipping bucket and drainage system, they are very likely to cause blockage. Blockage will not only prevent rainwater from flowing into the tipping bucket normally, but also affect the tipping accuracy of the tipping bucket, thereby increasing the measurement error and may even cause instrument failure, seriously affecting the accuracy of rainfall measurement and the long-term stable operation of the instrument.
