Swinging type wave energy device issues before death by pendulum mass in the effect of wave force or swings up and down, and wave energy is converted to the kinetic energy of balance staff, then kinetic transformation become the kinetic energy of Hydraulic pump by the hydraulic pressure installation that is connected with balance staff and then change into electric energy.Transformation efficiency is high on the one hand for pendulum device, can combine easily on the other hand, thus greatly improve the conversion efficiency of device with phase control technology.But swinging type wave energy device not only adds the link that balance staff kinetic transformation becomes Hydraulic pump kinetic energy, and the maintenance of machinery and hydraulic mechanism is comparatively difficult.
Poly-ripple reservoir wave power device is proposed by Falnes and Budal of Te Longmu university of Norway the earliest, utilize Road narrows that the wave energy of wide scope is gathered in very little scope, wave energy is changed into potential energy to be stored in storage reservoir and to generate electricity, energy density can be improved, good reliability, maintenance cost is low, and system is exerted oneself stable, hardly by wave height and the impact in cycle; Deficiency is because it generally needs to be fixed on specific position, and power station is built and had higher requirements to landform, not easily promotes.
Oscillating float type wave power device is the Wave energy electric generator grown up on the basis of oscillaton water column type device, by oscillating floater, wave energy is converted to the reciprocating machine energy driving oil hydraulic pump, then the hydraulic energy of instability is converted to stable hydraulic energy by energy snubber district, convert stable hydraulic energy to stable rotating mechanical energy by oil hydraulic motor again, send stable electric energy finally by generator.Advantage is quite obvious, and not only conversion efficiency is higher, and decreases underwater construction, builds easily, with low cost.But its oscillation frequency is subject to vibration frequency restriction, and stability of motions is not high, if adopt rotary generator, also needing mechanical for vibration conversion of motion is Rotational mechanical movement.
Visible, present stage most study, most widely used four kinds of Wave energy electric generators link of wave energy being changed into electric energy is more, and all do not make full use of the inertia of transmission part, can not take into account electric energy conversion high efficiency well, to the high applicability of various landform, and the high reliability run.
