Description

Technical Field

[0001] The utility model relates to the technical field of precipitation measurement, in particular to a tipping bucket rain gauge clogging alarm device. Background Art

[0002] 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. Its accuracy is directly related to the reliability of the measured data. Especially in the effect test of artificial rainfall and meteorological scientific research, its measurement accuracy is particularly important.

[0003] In Northwest China, due to dry air and strong winds, the net cover of the tipping bucket rain gauge is often blocked by sand, pebbles, fallen leaves and other objects, resulting in precipitation not being able to flow into the tipping bucket from the rain receiving port in time, causing errors in rainfall data. When the rainfall intensity is high, rainwater sometimes overflows from the rain receiving port to the outer shell, which not only poses a great challenge to accurate rainfall observation, but also brings great difficulties to instrument maintenance, especially for rain gauges set up in remote areas or mountainous areas. Since the blockage of the net cover cannot be discovered in time, the observation data cannot be used.

[0004] Therefore, a tipping bucket rain gauge blockage alarm device is proposed. Utility Model Content

[0044] Furthermore, since the shell 1 has a certain height, sand and soil are not easy to enter the shell 1, which further improves the monitoring accuracy of precipitation.

[0045] First, rainwater will enter the first funnel 15 through the second funnel 17 and the outlet pipe 18, and then enter the inside of the tipping bucket 12 through the first funnel 15. When the rainwater inside the tipping bucket 12 accumulates to a certain amount of water, the tipping bucket 12 will tilt to a certain extent under the action of gravity.

[0050] Working principle:

[0051] First, rainwater will enter the first funnel 15 through the second funnel 17 and the outlet pipe 18, and then enter the inside of the tipping bucket 12 through the first funnel 15. When the rainwater inside the tipping bucket 12 accumulates to a certain amount of water, the tipping bucket 12 will tilt to a certain extent under the action of gravity. At this time, the rainwater inside the tipping bucket 12 will enter the collection barrel 19 and then be discharged from the outlet pipe 21.
