Description

Single valve formula U-tube oscillating water column is to the double variable-pressure turbine apparatus for generating electricity by wave force of dress
Technical field
The present invention relates to wave-energy power generation technical fields more particularly to a kind of single valve formula U-tube oscillating water column to the double punchings of dress Dynamic turbine apparatus for generating electricity by wave force.
Background technique
Wave energy resource is contained abundant, and developing and utilizingpotentiality is huge.But due to wave energy is unstable, marine environment is severe, The factors such as seawater corrosion, sea organism attachment, development and utilization ocean wave energy are with high costs.These costs are mainly manifested in device Material cost, construction cost, switching mechanism cost, dispensing, transport and cost recovery, anchoring cost, maintenance cost etc..
Wave power utilization technology is many kinds of at present, and floating-type wave energy becomes research because its adaptation is wide using technology Mainstream, most floatation type technologies can be divided into 3 major class: floating oscillating water column technology, the more unrestrained technology of floating and floating oscillation Float technology, as shown in Figure 1.Floating oscillating floater technology is to push a floating body with respect to another floating body (support using wave Platform) translation or rotation conversion energy, i.e. the wave energy mechanical energy that is converted to floating motion first, then by hydraulic system or Linear generating system or mechanical mechanism are converted to electric energy.Device based on technology development must be bis- (more) floating bodies and slip into Or partly slip into seawater, this feature means that INTERACTION PROBLEMS can not between stock utilization low (dual or multi floating body), floating body It avoids, sea organism attachment influences that big, the release time is long (floading condition adjusting needs time and equipment), easy mechanical breakdown out, it is difficult to tie up It repairs, cost performance is influenced to improve limited by technology path.Floating more unrestrained technology is the effect of climbing using wave, and wave energy is turned It is changed to the potential energy of seawater, the device characteristic based on technology development is single floating body (carrying platform), and device will undertake conversion carrier The weight of (seawater), therefore its structure and scale is huge, intensity requirement is high, under the collective effect of wind, wave and stream, anchoring system is multiple Greatly, the same contact with sea water of the hydraulic turbine is influenced by sea organism attachment, is developed slowly for miscellaneous, investment.Floating oscillating water column technology is to tie Cavity is set in structure object, pushes air movement using the water column in cavity, the air push air turbine and generator of movement are defeated Electric energy out.Common cavity form is straight tube, bend pipe or inclined tube, and slip into seawater for cavity one end, and the other end installs air after shrinking Turbine and generator form a gas chamber between air turbine and seawater.The technical characterstic is single floating body, and stock utilization is high, no There are problems that collision, air turbine and generator are located on the water surface not to be influenced by seawater and sea organism attachment, easy to maintenance.Floating Oscillating water column technology has silent oscillation and two kinds of sports type.It is substantially motionless to float silent oscillation oscillating water column technology floating body, water in cavity The movement of column directly acts on generation, such as " huge whale " number device of Japan mainly by wave, and this kind of Technology Energy transfer efficiency is not It is high.Have the shortcomings that construction cost is high, ocean engineering is costly, safety is not high in existing wave power utilization technology.
Summary of the invention
The purpose of the present invention is overcoming above-mentioned the deficiencies in the prior art, a kind of single valve formula U-tube oscillating water column is provided to dress Double variable-pressure turbine apparatus for generating electricity by wave force.
