Description

Portal shaft generator

technical field

The utility model relates to a small power generation device, in particular to a device which utilizes the torsion force of a door shaft to convert kinetic energy into mechanical energy for power generation and stores it with a storage battery.

Background technique

According to the principle of leverage, the door panel rotating around the axis can be regarded as a lever, and the torsional force is relatively large near the position of the rotation axis, which can make the heavier flywheel move. According to experiments, the average work done by pushing a door with a radius of one meter is about 80J. Especially in public places where some loose-leaf door panels are frequently opened and closed, the energy consumed by pushing the door every day will be very large. When the portal shaft is connected to the heavy flywheel through gear transmission, more energy will be consumed due to the work done against the resistance. It can be seen that if this part of energy is stored, it will be a very considerable number. At present, there is no device for generating electricity using a flywheel driven by portal shaft torque.
