Will the ceiling fan fall down while operating？
Do you also have such childhood fears? In the summer time will often check the ceiling fan overhead, worried that the running vibration of the ceiling fan will suddenly fall down and hit our bodies?
First let's understand the structure of the ceiling fan. In the following illustration, we see that the ceiling fan is connected to the ceiling by a U-shaped steel bar, which serves as a carrier for the transition between the main body of the ceiling fan and the ceiling, and the quality is very good. The ceiling fan rod and the motor are connected and locked by several fastening screws. u-shaped bars and fastening screws connect the ceiling, ceiling fan rod and ceiling fan motor perfectly, and the security is very high.
Then we learn more about the force process of the ceiling fan. When the ceiling fan is at rest, it is subjected to a tension equal to the gravity of the ceiling fan itself.
When the ceiling fan began to operate, the blades began to rotate will produce a downward force on the air, at this time the ceiling fan by the tensile force is equal to the ceiling fan's gravity minus the air reaction force, so the ceiling fan in operation when the tensile force will be less than the weight force, so the ceiling fan will not fall down.
The tensile force of a ceiling fan at rest is greater than the tensile force in motion, so if the ceiling fan has the possibility of falling, the situation is generally at rest or started from a standstill.
If the ceiling fan happens to have a very small probability event - falling down, that in the stationary state for the "bang" fall down, if the ceiling fan from 2.5 meters above the ground position down, and just someone sitting under the ceiling fan, assuming that the head is located in the ground height 1.2 meters, then the fall distance of 1.3 meters, gravitational potential energy is 65 joules, into kinetic energy speed of 5 meters per second, the damage caused to the human body for the head slight pain.
When the ceiling fan in the static start state fell down, most of the old ceiling fan is in disrepair, its fastening screws loose, crumbling led to, when falling down when the connection wire break, the ceiling fan lost power supply, rotation speed slowed down, if the ceiling fan below someone, then the injury to the human body is bruises.
So when we use to a certain time to check the ceiling fan, not only to check whether the operation process is smooth, but also to check each connecting parts such as screws, blades have no loose, the ceiling fan will be lifted from the risk, so that we are more safe and secure to use it！
