It has the advantages of accurate time, automatic data recording, and convenient data collection and compilation. Precipitation is an important meteorological element. The observation of precipitation is of great significance for meteorological, hydrological, marine, environmental observations, as well as for the safety of aviation and railway transportation. The rain gauge is an important instrument for observing precipitation, and its accuracy is directly related to the reliability of the measured data.

[0003] When using an existing tipping bucket rain gauge, it is usually fixed in an outdoor environment. However, in the process of collecting rainwater, impurities such as branches will flow into the measuring device along with the rainwater, which will affect the accuracy of the rainfall and affect its use. In actual production, according to the different accuracy required by customers, it is necessary to adjust the different preset rainfall capacity of the tipping bucket. Currently, the market mostly adopts the method of installing adjusting bolts on the bases on both sides under the tipping bucket, and adjusting the tipping angle of the tipping bucket by adjusting the height of the bolts, so as to adjust the rainfall capacity of the tipping bucket. Such an adjusting device requires manual adjustment of the heights of the two adjusting bolts respectively during adjustment, which is labor-intensive and there will be errors in the manual adjustment of the rainfall capacity on both sides of the tipping bucket.

[0022] The implementation principle of the tipping bucket structure of a tipping bucket rain gauge in the embodiment of the present application is as follows: when in use, rainwater drips into the interior of the water diversion funnel 4, and impurities and dust in the rainwater can be filtered through the primary filter screen 5 and the secondary filter screen 12. The filtered rainwater flows through the outlet pipe 6 onto the two tipping buckets 21. When the rainwater in one of the tipping buckets 21 reaches a certain weight, the tipping bucket 21 drives the fixed block 23 to rotate with the shaft rod 24 as the axis. At the same time, the rotation of the tipping bucket 21 drives the roller 22 to press the rectangular plate 19 downward. The downward pressing of the rectangular plate 19 drives the support rod 18 to move downward inside the sleeve 28. At the same time, the rectangular plate 19 drives the first spring 17 and the second spring 26 to contract.
