Description

Fan with diversion air collection device

The invention relates to a wind power device, in particular to a fan with a deflector wind collecting device capable of providing stable kinetic energy.

Generally, a fan that is driven by natural wind drives the fan blades with wind force, so that the fan blades turn to work for the generator or mechanical component. It can convert wind energy into electrical energy or mechanical energy to meet the energy needs in life. However, the strength of the natural wind changes with time, which not only causes the speed of the fan to fluctuate, but when the wind force is less than the dynamic friction of the fan blade rotation, the fan will stop running, and the wind force must be greater than the static friction of the fan blade rotation The fan can be restarted to operate, therefore, when the amount of natural wind continues to be low, it is easy to cause the fan to shut down for a long time and affect the energy supply.

Under the condition that natural wind can not provide stable power, in order to enable the fan to maintain low-speed operation to avoid the loss of energy conversion efficiency caused by the fan standing still, the conventional fan can be connected to the generator by reverse connection or other power sources in advance.
