The invention provides an anti-clogging rainfall measuring device and a measuring method, and relates to the technical field of meteorological monitoring, the anti-clogging rainfall measuring device comprises a base and a collecting part, the collecting part is arranged on the base, impurities such as fallen leaves doped in rainwater can be separated through a conical filter screen, the impurities such as the fallen leaves can fall above the conical filter screen, and the collecting part is arranged on the base; the lifting part can drive the conical filter screen to rotate, fallen leaves can be effectively prevented from covering the conical filter screen to affect rainwater collection of the collection box, and on the contrary, when a gap exists between the top end of the collection box and the inner top wall of the shell, impurities such as the fallen leaves can be discharged from the collection box through the gap; the adjusting part can drive the shell and the collecting box to move upwards, after the shell and the collecting box move upwards, rainwater in the collecting box can flow into the water storage bottle through the lifting part, the rainfall is calculated by observing weight data of the water storage bottle, the influence of impurities such as fallen leaves on the rainwater collecting and measuring process is effectively avoided, and the rainwater collecting and measuring efficiency is improved. And the accuracy of rainwater measurement is improved.
