Abstract
The invention relates to a sea pressure power generation device which is characterized in that the power generation device is erected by a fixed bracket. A bearing structure is arranged on the top of the fixed bracket. The bearing supports a framework structure in a wind indicator structure. Each small frame is provided with a piezoelectric plate made of a piezoelectric material. The piezoelectric material comprises piezoelectric ceramic or piezoelectric polymers such as PVDF (Polyvinylidene Fluoride).
Description
Technical field
The present invention relates to a kind of ocean pressure generating set.
Background technology
Oceanic energy is the rare resource of human development as a kind of regenerative resource of cleaning.But existing oceanic energy exploitation develops comparatively slow owing to be limited by development cost and efficiency.At present, utilize power generation with marine energy to mainly contain sea wind generating, seawave power generation, tidal power generation etc.Typical seawave power generation has: wave energy---air force---air turbine---generator; Wave energy---oil pressure---servomotor---generator; Wave energy---water-head---hydraulic turbine---generator.And in fact, oceanic energy mainly concentrates among the ocean, and is not only at ocean surface.Surface, ocean wave never stops and contains a large amount of sea wave energies, is all containing constantly transformation sea pressure energy among the ocean every.At present, piezo technology becomes better and approaching perfection day by day, and Japan utilizes piezo technology development piezo-electric floor to provide energy for ticket-validating machine, day generation energy 0.14 kilowatt hour.Stamford research and utilization piezopolymer is collected ocean wave energy, and power can reach 1.2 watts.The invention provides a kind of device that utilizes the extra large pressure energy among the piezo technology exploitation ocean.
[0003] summary of the invention
Insert fixed support (3) at marine bottom (4), this fixed support top is bearing arrangement (2), bearing holds up the frame structure (1) such as wind vane, each small frame (5) is installed the piezoelectric board (6) that piezoelectric is made, and piezoelectric comprises piezoelectric ceramic or piezopolymer such as PVDF etc., and piezoelectric board (6) surface under the variation effect of hydraulic pressure the polarization reflection can occur, produce electromotive force, both side surface is connected wire, and will generate electricity derives, and stores.Piezoelectric plate surfaces is carried out insulation processing.The piezoelectricity placement direction has two kinds, and a kind of is to be parallel to horizontal direction, a kind of horizontal direction that is perpendicular to.
