1. A wave-driven gravity type power generation device comprising:
two power generation modules, each comprising a stator set and a rotor set, wherein an electromagnetic interaction is produced between the stator set and the rotor set to generate electricity, each rotor set having a respective shaft;
a pulley module, comprising a sliding groove and a counterweight, wherein
the counterweight is arranged in the sliding groove and moves back and forth along the sliding groove in a first direction and a second direction by water waves, wherein the first direction and the second direction are opposite to each other;
two transmission mechanisms, each comprising a drive and a gear module connected to the drive, wherein
each drive is combined with the counterweight and moves along the first direction and the second direction with movement of the counterweight,
each gear module is drivingly linked with the respective shaft of the respective rotor set such that the shaft is kept to rotate in one direction for continuously generating the electricity; and
an installation base comprising a base body and at least two installation parts extending from a side of the base body, the sliding groove being disposed on the base body, wherein each of the at least two installation parts comprises a carrier body and a supporting body, wherein one of the two power generation modules and one of the two transmission mechanisms are disposed on each of the carrier bodies of the at least two installation parts, wherein each of the supporting bodies comprises at least one fastening hole for adjusting a height of the carrier body,
wherein one of the two power generation modules and one of the two transmission mechanisms are disposed on one side of the sliding groove and another one of the two power generation modules and another one of the two transmission mechanisms are disposed on an opposite side of the sliding groove, the two power generation modules and the drive and the gear module of the two transmission mechanisms are installed at the same horizontal level for the counterweight to slide smoothly and preventing the drive from falling off.
