Description
Technical field
It the present invention relates to the use of power generation with marine energy technology more particularly to a kind of swing wave power conversion structure and with floating
The swing Wave energy converter of array bottom hinge of damping sheet.
Background technique
As the important material base of human survival and development, fossil energy supports the century-old basic existence of the mankind nearly two
Need with social development demand, however, having along with itself because of exhaustive exploitation and use of the mankind to fossil energy
It is non-renewable, cause fossil energy gradually to move towards exhausted.
In addition to this, the burning of fossil energy brings huge pollution problem, and the discharge of sulfur dioxide and flue dust is close
Acid rain aggravation in several years and the frequent arch-criminal of haze phenomenon, therefore develop and become using various novel renewable and clean energy resources
One of project urgently to be resolved on our times.
Ocean covers the surface of the earth 79%, wherein the huge ocean energy for including is that the Nature vouchsafes the one of the mankind
The huge energy wealth of pen, the energy of ocean exists in the form of tide, wave, temperature difference, salinity gradient, ocean current etc., great to open
Send out potentiality.The mankind started from for 18 end of the centurys to the development and utilization of wave energy, and eighties of last century the seventies start world oil danger
After machine outburst, the attention of the littoral some countries in the European North Sea has been obtained.By effort in more than 40 years, one have now been formed
Part can put into the wave energy generating set of practical application.
Possessed wave energy resource has a very wide distribution in the ocean in China coast region, and its energy density relative to
Other areas are lower.In the geographic coverage of ocean wave energy development of resources, the marine environment of immediate offshore area is mild with respect to off-lying sea,
Inshore Wave energy is lost limited by sea bottom friction simultaneously, and wave energy level is abundant compared with littoral sea.Moreover, in coastal waters domain, wave
Wave energy generating set is easy to launch and maintenance, wave energy resource are easy to develop.With reference to " Heilongjiang Province youth science fund 2016-
Body of the report -20161011 " wave energy generating set of early stage is mostly bank base stationary structure, that is, it needs wave energy apparatus to put
It is placed on the fixation water conservancy project basis built around seashore or other buildings.With the raising of technology, wave energy generating set
Occur two kinds of forms of offshore seat seabed formula device and floatation type device again.The knot of offshore seat bottom type device and the fixed device of bank base
Structure and working principle are roughly the same, and floatation type device does not need then to be mounted on fixed building, the general idea is that will
Wave energy electric generator is mounted on one and floats on the carrier on the water surface or platform, such as wave-energy power generation ship；Or directly will
Wave energy generating set is designed to the structure of floatation type, such as " sea snake " the floating-type wave energy power generation of Pelamis company, Britain
Device, main body are made of the floating drum of several cylindrical types, by being hingedly connected together between floating drum, in the work of wave
Under firmly, floating drum generates relative motion, and then drives the hydraulic device capture wave energy for being mounted on hinge joint.
In fixed wave energy generating set, no matter being mounted in bank base or offshore, require to build corresponding water
Work basis or building, at high cost, construction difficulty, reduce the economy of wave energy generating set.In addition, stationary structure
Buffer capacity it is poor, wind and wave resistance impact property is weak, reduces the reliability and stability of power generator itself, increases maintenance
Cost, so that wave-energy power generation performance difficulty, replicability is reduced.
For these reasons, floatation type structure is all gradually transferred to the research emphasis of wave energy apparatus both at home and abroad now
Come up.But most of floatation type device is only made of single float and wave energy capture column, is only capable of obtaining the energy of unidirectional wave
Amount, generating efficiency is low, and stability is poor.For China coastal seas since by the influence of topography, wave breaking is significant, unidirectional capacitation device is difficult
Wave energy is made full use of with realizing.

On Buddhist nun's plate and eight swing wave power conversion structures are arranged by circumference array and its corresponding support is also respectively installed at damping sheet
On, the guide rail of the swing wave power conversion structure is fixedly mounted on the center on damping sheet and being located at circumference array.
Compared with prior art, the beneficial effects of the present invention are: the present invention by multiple swing Wave energy converters with battle array
Array structure is articulated on floating damping sheet, the wave potential energy of multiple directions can be passed through the hydraulic dress on wave energy capture column
It sets while being converted to electric energy.Array architecture can improve the frequency response range of device, make float by the liter after wave action
Drop movement is more obvious, improves generating efficiency.The present invention can solve the capacitation direction of current floating-type wave energy power generator
Disadvantage single, wave energy utilization rate is low and stability is poor.
