For this reason, we propose a hydroelectric power generation auxiliary device. Utility Model Content

A hydroelectric power generation auxiliary device, in this article, one end of the drive shaft passes through the vortex tube and can contact the water source through the blades at the end of the drive shaft to drive the rotation, and the power of the water flow is then transmitted to the motor shaft through the drive shaft. As the electric energy is converted through the generator, the drive shaft and the motor shaft are installed in a linkage control manner. When the linkage seat is controlled to approach the drive shaft by the toggle lever outside the rotating seat, the linkage plug shaft at the end of the linkage seat can pass through the driving socket inside the driving seat, so that the drive shaft and the motor shaft maintain a limited linkage state. At this time, the drive When the dynamic shaft is rotating, the driving shaft can increase the driving rotational force on the motor shaft through the linkage plug-in shaft plugged into the driving seat. If the reducer of the power generation equipment fails, the rotating seat can be controlled to move to the other side by toggling the lever to remove the linkage plug-in shaft at the end of the linkage seat from the driving socket. At this time, the driving shaft and the motor shaft are disconnected.
