Description

Technical Field

[0001] This utility model relates to the field of rainwater metering technology, and more specifically, it relates to a tipping bucket rain gauge. Background Technology

[0002] Hydrometeorology, belonging to geography and hydrology, refers to the interaction between water on the land surface and in the atmosphere. Rainfall, from a meteorological perspective, usually refers to the amount of water vapor that condenses in the air and falls to the ground, including dew, frost, hail, snow, etc. Condensation is not included. Rainfall is the depth of rainwater that falls to a horizontal surface within a certain period of time. The tipping bucket rain gauge is a common rain measurement instrument, widely used in meteorological stations, hydrological stations, agriculture, and environmental monitoring. Its working principle is based on the mechanical action of the tipping bucket. When rainwater falls into the tipping bucket, it will tip over after reaching a certain weight, pouring the rainwater into a collection bucket. Each tipping triggers a switch and records the rainfall. By accumulating the number of tippings, the total rainfall can be calculated.

[0003] However, most existing tipping bucket rain gauges are open-top designs, which makes it easy for insects, leaves, and dust in the rainwater to enter the device during the rain measurement process, causing blockages inside the device and affecting the measurement results.

[0004] Furthermore, existing tipping bucket rain gauges cannot be fixed to the ground surface, which limits their use. When it rains, the rain gauge is prone to tipping over, thus affecting the normal operation of the device. Utility Model Content
