Description

Technical Field

[0001] This utility model relates to the field of meteorological detection teaching aids technology, specifically to an interlocking louvered box teaching aid. Background Technology

[0002] Stevenson screens are essential equipment in meteorological observations for housing temperature and humidity sensors. They protect these sensors from solar radiation and wind and rain, ensuring the accuracy of the measured data. Understanding the structure and function of Stevenson screens is crucial for comprehending meteorological data acquisition in meteorological teaching and popular science education.

[0003] However, current meteorological teaching and popular science activities rely heavily on textual descriptions and pictorial displays when explaining Stevenson screens, making it difficult for learners to intuitively grasp the layout of the instruments inside. Existing physical Stevenson screens cannot be opened to display internal details during observation due to observational regulations; while some commercially available Stevenson screen models suffer from overly simplistic structures, lack of disassembly or assembly capabilities, failing to accurately reflect the complex internal structure. This results in learners' insufficient understanding of the working principles of Stevenson screens and the installation methods of meteorological instruments, limiting the effective dissemination and learning outcomes of meteorological knowledge.
