Definitions

  • the present disclosure relates to energy harvesting devices and, more particularly, relates to an energy harvesting device that converts multiaxial translational and rotational motion to unidirectional rotational motion.
  • Wind energy is seasonal. Even during windy seasons, wind does not remain constant and varies periodically. Similar to Solar Energy, Wind Energy systems also require investment in stand-by sources to keep up with the demand when the winds slow down or drop to insignificant levels.
  • Wave energy when compared to the other two, is more reliable. Over a wider time period a reasonably unceasing wave power supply can be expected. The energy variations are, however, not as significant as Solar and Wind Energy. But in shorter time intervals (in minutes and seconds) Wave Power fluctuates momentarily. This requires a wave power absorption and conversion system that can store momentary peak power and release for supplementation during momentary periods of low power.
  • the Wave Power industry today stores this momentary excess energy in a battery as electrical energy or in a pressure vessel as pressure energy. The stored energy is utilized within short periods of time (minutes or seconds) and do not necessitate long term (in hours or days) storage.
  • the present wave energy conversion devices either directly run an electric generator that stores electric energy in battery banks or operates a hydraulic motor that stores pressure energy in pressure vessels. The stored pressure is then released at a constant rate to run a hydraulic turbine / motor coupled to an electric generator.
  • this member has to perform two functions— one to convey the heave motion to the device for absorption and conversion of the heave forces and other to hold the floating device in place by withstanding the unused forces caused by motions associated with sway, pitch, surge etc. This results in other complex forces like bending, shear, torsion etc. that this member has to withstand.
