Description

Technical Field

[0001] This utility model relates to the field of ventilation measurement technology, specifically to a portable wind speed measuring device for a large cross-section channel. Background Technology

[0002] Ventilation systems are crucial for ensuring the health, hygiene, and safety of the internal environment of structures such as buildings, tunnels, and mines. Once activated, the ventilation system directs airflow through ventilation corridors (such as ventilation passages, tunnels, and mine roadways). The wind speed distribution across the cross-sections of these corridors is a key parameter for analyzing the effectiveness of the ventilation system's airflow organization; therefore, accurately measuring the wind speed across the ventilation corridor cross-sections is extremely important.

[0003] In actual engineering projects, ventilation corridors have large areas, which differ from the standard cross-sectional wind speed measurement conditions in the laboratory. The main technical challenges of large cross-sectional wind speed measurement on engineering sites are as follows: Existing rotary blade wind speed measuring devices require staff to hold the instrument by hand when measuring wind speed. Therefore, it is difficult to operate when measuring wind speed in large, non-uniform cross-sections. The layout and positioning of measuring points on large cross-sections are also difficult, which reduces the measurement accuracy. Utility Model Content
