Description

Technical Field

[0001] The utility model relates to the technical field of meteorological monitoring equipment, in particular to a shell structure of a tipping bucket rain gauge which is convenient for inspection and maintenance. Background Art

[0002] With the intensification of climate change and the increasing importance of water resource management, accurate measurement of precipitation has become an indispensable part of meteorological observation and hydrological research. As a widely used measuring device, the tipping bucket rain gauge is popular because of its simple structure and sensitive response. However, the tipping bucket rain gauges in the prior art generally face a common problem: the blade-like edge of the rain receiving port design (usually set at an angle between 40° and 45°), although conducive to the smooth introduction of rainwater, has exposed significant drawbacks in actual maintenance operations.

[0003] Specifically, the sharp edges of these cutting edges not only increase the difficulty of maintenance operations, but also pose potential safety hazards. When performing routine cleaning operations, such as removing foreign matter such as fallen leaves and dust, or regularly cleaning and calibrating the bucket components, operators must be extremely careful to avoid being scratched by sharp edges. In addition, the edges of the cutting edges are easily damaged during disassembly and reassembly, causing the surface coating to fall off, which not only affects the appearance, but more importantly, reduces the accuracy and service life of the instrument. Damage to the coating may cause rust, further affecting the reliability of the measurement results, thereby accumulating errors in long-term use.

[0004] In addition, in the conventional bolt connection and fixing method, there are many parts such as bolts and gaskets. Since the equipment is generally installed in the field, a period of equipment maintenance and cleaning process is required after the bolts are removed. Once a bolt is lost during this process, the stability of the device cannot be guaranteed after reinstallation after the operation. Summary of the invention
