Description
Technical field
The present invention relates to field of new energy utilization, it is provided that a kind of float-type wave power device survival ability of improving
Structure.
Background technology
In the world today, along with the disposable energy is petered out and the aggravation of environmental pollution, people get over sight
Carry out the development and utilization of the regenerative resource of the most trends of purchasing cleaning.Wave energy is regenerable marine energy
Important component part, is the regenerative resource of a kind of cleaning.
Wave energy generating set is varied, but the most too many wave-energy power generation engineering puts into business
Change and run.Wave energy apparatus Years Of Service under conventional sea situation and at wave load under the structure that causes
Fatigue problem becomes the big bottleneck hindering wave energy to develop；It addition, wave power device is at severe sea condition
Under survival ability hinder again the another big obstacle of its commercialized running.This will decide wave largely
The cost of energy generation engineering puts into.Therefore, reduce the inessential wave load of wave power device and improve that it is severe
Survival ability under sea situation, is the key of wave energy research on utilization.Hollow structure is in ocean engineering common one
Planting works, it is widely used in the structure such as breakwater, harbour pile.If can be by effectively utilizing thoroughly
Hollow structure thing reasonably transforms tradition wave power device, to reduce inessential wave force and the motion response width of device
Value, can improve wave power device survival ability.
Summary of the invention
The present invention is directed to deficiency of the prior art, it is proposed that a kind of raising float-type wave power device survival ability
Device.
Technical scheme:
A kind of structure improving float-type wave power device survival ability, this structure includes cylindrical float 1, transmission
Mechanism 7 and energy output system 8；Described cylindrical float 1 external wall of upper portion is transmission outer wall 2, outside transmission
With inner prop 3 in wall 2, inner prop 3 and cylindrical float 1 bottom are integrated convex shape, inner prop 3 and transmission
Gap is had before outer wall 2；Cylindrical float 1 bottom outer wall is provided with ballast pump 4, autonomous load or unload
Ballast water；Described energy output system 8 is hydraulic pressure generating system, is fixed on seabed 6, is floated by cylinder
The up and down motion of son 1 drives hydraulic pressure generating system generating；Described drive mechanism 7 is steel anchor chain, is suitable for
In relatively deepwater regions.
The drinking water of cylindrical float 1 can Autonomous Control, when severe sea condition, can be pressurizeed by ballast pump 4
The mode carrying water realizes deeper drinking water, and then reduces buoyancy aid horizontal wave force under severe sea condition and motion
Response, to realize the self-protection function of wave power device under severe sea condition.
Beneficial effects of the present invention: use with the cylindrical float of transmission outer wall 2 as cylindrical float 1,
This type works simple shape, it is simple to manufacture.Under conventional sea situation, the shallower draft of cylindrical float 1,
The drinking water h of transmission the outer wall 2 and drinking water h of whole device1Ratio h/h1The least.Limit at drive mechanism 7
Under system, cylindrical float 1 mainly pumps with wave, and then drives energy output system 8 to enter
Row generating.Under more severe sea condition, by the way of ballast pump 4 adds ballast water so that parameter h/h1
Increasing, so may result in the horizontal wave force suffered by float 1 and heaving response is the most significantly smaller, this has
It is beneficial to improve device survival ability under more severe sea condition.
