TECHNICAL FIELD

[0001] The present utility model relates to the technical field of meteorological monitoring equipment, in particular to a housing structure for tilting rain gauges for easy overhaul and maintenance. STATE OF THE ART

[0002] With the intensification of climate change and the growing importance of water resource management, accurate precipitation measurement has become an indispensable part of meteorological observation and hydrological research. The tilting rain gauge is a widely used measuring device, popular for its simple structure and sensitive response. However, there is a common problem with the current tilting rain gauges: the cut-line edges (usually at an angle between 40° and 45°) at the rainwater collection opening. Although these edges are conducive to the smooth discharge of rainwater, they have significant drawbacks in actual maintenance.

[0003] In particular, the sharp edges of these cut lines not only complicate maintenance but also pose a potential safety hazard. During routine cleaning tasks, such as removing leaves, dust, and other foreign matter, or regularly cleaning and aligning the tilting components, the operator must exercise extreme caution to avoid cuts caused by sharp edges. Furthermore, the edges of the cut lines are susceptible to damage during disassembly and reassembly, leading to the loss of the surface coating. This not only affects the appearance but, more importantly, reduces the accuracy and service life of the device. Damage to the coating can lead to corrosion, which further compromises the reliability of the measurement results, resulting in errors accumulating over long-term use.

[0004] Since the devices are typically used on-site, a certain amount of time is required for maintenance and cleaning of the devices after disassembly of the screws. If the screws are lost during this process, the stability of the device after reassembly after operation cannot be guaranteed. CONTENT OF THE PRESENT UTILITY MODEL
