1.What are the precautions when using the wind vane?
Safe distance: When using the wind vane, make sure to keep a sufficient safe distance from surrounding objects and people.
Stable support: The weathervane needs to be placed on a stable surface to ensure that it can remain vertical and not fall over.
Wind speed: When using the wind vane, pay attention to the current wind speed situation.
Weather conditions: Wind vanes are useful for measuring wind direction, but in certain extreme weather conditions, such as storms or lightning storms, it may not be safe to use a wind vane.
Maintenance: Regularly check the status of the wind vane to ensure that there is no damage or air leakage.
2.What is the principle of action?
When the direction of the wind forms a certain angle with the wind vane, the wind exerts pressure on the wind vane, and this force can be decomposed into two wind forces parallel and perpendicular to the wind vane.
Because the wind vane head has a relatively small wind receiving area and the tail wing has a relatively large wind receiving area, the wind pressure felt is unequal.
The wind pressure perpendicular to the tail wing produces a wind pressure moment, which makes the wind vane rotate around the vertical axis until the wind vane head is just facing the wind.
When coming and going, due to the balanced force on both sides of the wing plate, the wind vane is stable in a certain direction.
