NOVELTY - The apparatus i.e. wave power generation apparatus (100), has a wave power conversion module comprising a power transmission drive joined to an input shaft to translate a bidirectional rotation of the input shaft into a unidirectional rotation. An output shaft of the conversion module is joined to the power transmission drive to transfer the unidirectional rotation. A generator of the conversion module is joined to the output shaft to generate electrical energy in response to the unidirectional rotation of the output shaft and transfer the electrical energy to a power transmission cable.    USE - Apparatus i.e. wave power generation apparatus, for use in a shallow sea, lake and ocean shore, to convert wave energy into electrical energy.    ADVANTAGE - The apparatus replaces few of rigid float guides in upper frame with non-rigid float guides made of an elastic material, thus absorbing shock on wave power generation floats in rough waves and lowering manufacturing cost. The wave power conversion module that generates electricity, is placed inside a wave power generation float and is positioned above a water's surface, thus minimizing negative effects due to saltwater such as corrosion of parts in wave power conversion module, and simplifying corrosion preventing process, and hence decreasing operation cost. The apparatus improves power quality by using the generator, thus decreasing development cost of the apparatus. The apparatus prevents loss of power from tangling or twisting of power transmitting cable caused due to rotation of wave power generation float. The apparatus stops inflow of saltwater through air sealing tube by the pressure of compressed air in air sealing tube, so that sealing of wave power conversion module is achieved without using an existing mechanical seal that requires continuous maintenance. The apparatus reduces response time of a rotor in generator inconsideration of fluid or gas as sealants against saltwater to be used inside the generators. The apparatus is easy to install and operate inconsideration of a size of the apparatus with reduced power usage, and reduces maintenance time and cost with increased efficiency. The device is prevented from damage caused due to storm.    DESCRIPTION OF DRAWING(S) - The drawing shows a side perspective view of a wave power generation apparatus.
