Description

Technical Field

[0001] This utility model relates to the field of rainfall measurement technology, and in particular to a weighing-type rainfall measurement device. Background Technology

[0002] Under natural conditions, precipitation includes rain, snow, hail, etc. Rain and snow are the most common forms of precipitation. Therefore, devices that can accurately observe both rainfall and snowfall are very important for precipitation observation.

[0003] Chinese Patent CN221507177U discloses a weighing rain gauge, comprising a weighing rain gauge body for measuring rainfall. The weighing rain gauge body has a rain-collecting funnel at its top for collecting rainwater. Two fixing blocks are located on the outer side of the top of the weighing rain gauge body, and a mesh protective cover for intercepting fallen leaves is rotatably connected to the inner side of the two fixing blocks. Rainwater is collected sequentially by several water collection troughs, which rotate downwards in sequence, causing the mesh protective cover to rotate frequently. When the mesh protective cover rotates, leaves falling onto it are scraped off by the rain-collecting funnel, ensuring that the outside of the mesh protective cover remains unobstructed. This prevents leaves accumulating on the mesh protective cover from affecting rainwater collection and reducing measurement accuracy.

[0004] The shortcomings of the above-mentioned existing technical solutions are as follows: While the mesh protective cover can intercept fallen leaves, snowflakes easily adhere to the mesh protective cover during snowfall. In freezing rain, freezing rain quickly condenses into ice on the mesh protective cover. The adhesion of snowflakes and the formation of ice layers increase the weight of the mesh protective cover, affecting its normal operation and hindering rainwater or snow water from flowing into the rain collection funnel, thereby affecting the accurate collection and measurement of rainfall by the rain gauge.

Weighing devices one and two work together to accurately record changes in the weight of the rainwater, enabling precise measurement of rainfall. The various parts of this device are tightly integrated, taking into account the characteristics of different precipitation forms while ensuring the accuracy and stability of the measurement.

During use, because the isolation net 35 is installed at the connection between the conical body and the spout, and the rain collection funnel 31 is supported on both sides of the weighing device 1 (4), snowfall will accumulate and be stored in the rain collection funnel 31 during snowfall. The weighing device 1 (4) can then weigh the snowfall to calculate the amount of snowfall. During freezing rain, freezing rain will accumulate and be stored.
