Description

Technical Field

[0001] This utility model relates to the field of wind speed measurement technology, specifically to a wind speed measurement auxiliary device. Background Technology

[0002] In vaccine manufacturing companies, a clean environment is crucial for ensuring vaccine quality, especially in the terminal sterilization process, which requires strict control throughout the entire production process. When handling products with exposure, a Class I clean environment must be maintained. Meeting the required air velocity is an important prerequisite for ensuring a clean environment. Therefore, air velocity needs to be measured to ensure compliance. When measuring air velocity, it is necessary to maintain a certain distance from the surface of the HEPA filter or the work surface, and measurements should be taken sequentially at different points.

[0003] In existing technologies, measurement personnel generally use handheld anemometers to make measurements. The operator visually estimates the vertical distance from the surface of the HEPA filter or the workbench and measures the points sequentially. However, the operator is prone to fatigue from looking up and holding the anemometer with their arm raised for a long time, and it is also impossible to accurately locate the specific points and heights, which affects the accuracy of the measurement results.

[0004] The utility model patent with announcement number CN212780870U discloses an integrated high-speed wind speed measuring device, which is equipped with a rotating rod, a rotating handle, a movable nut, a limiting rod and a first limiting groove, improving the practicality of the device. However, it does not disclose how to solve the problem of low accuracy of measurement results caused by operators visually estimating the vertical distance from the surface of the high-efficiency filter or the workbench.

[0005] The utility model patent with announcement number CN209460280U discloses an ultrasonic anemometer for field use. By setting up a first slide rod, a second slide rod, a locking hole, a threaded cylinder, a threaded column, and an anemometer body, it is convenient for operators to adjust the position of the anemometer body and adjust its height according to measurement needs, thus meeting the needs of use and facilitating the work of operators. However, it does not disclose how to solve the problem that operators are prone to fatigue from long-term operation with their heads tilted back and arms raised to hold the anemometer, and the inability to accurately lock the specific location, resulting in low accuracy of measurement results.

[0006] In summary, designing an auxiliary wind speed measurement device that can adjust the distance to the high-efficiency filter and flexibly adjust the anemometer's measurement position, thereby reducing the operator's workload and avoiding the impact of operator fatigue and visual errors on the accuracy of measurement results, has become an urgent problem to be solved.
