Description
Technical field
This utility model relates to field of new energy utilization, it is provided that a kind of knot improving float-type wave power device survival ability
Structure.
Background technology
In the world today, along with the disposable energy is petered out and the aggravation of environmental pollution, people get more and more sight
The development and utilization of regenerative resource of trend of purchasing cleaning.Wave energy is the important component part of regenerable marine energy, is
A kind of regenerative resource of cleaning.
Wave energy generating set is varied, but the most too many wave-energy power generation engineering puts into commercialization fortune
OK.Wave energy apparatus Years Of Service under conventional sea situation and at wave load under the fatigue problem of structure that causes become
Hinder the big bottleneck that wave energy develops；It addition, the survival ability that wave power device is under severe sea condition hinders again its business
Change the another big obstacle run.The cost that decide wave-energy power generation engineering largely is put into by this.Therefore, wave energy is reduced
The inessential wave load of device and the survival ability improved under its severe sea condition, be the key of wave energy research on utilization.Transmission is tied
Structure is a kind of works common in ocean engineering, and it is widely used in the structure such as breakwater, harbour pile.If can pass through
Hollow structure thing is effectively utilized reasonably to transform tradition wave power device, to reduce inessential wave force and the motion response width of device
Value, can improve wave power device survival ability.
Utility model content
This utility model is for deficiency of the prior art, it is proposed that a kind of float-type wave power device survival ability of improving
Device.
The technical solution of the utility model:
A kind of structure improving float-type wave power device survival ability, this structure includes cylindrical float 1, drive mechanism 7
With energy output system 8；Described cylindrical float 1 external wall of upper portion is transmission outer wall 2, with inner prop 3 in transmission outer wall 2, interior
Post 3 and cylindrical float 1 bottom are integrated convex shape, and inner prop 3 had gap before transmission 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, Gu
Due to seabed 6, hydraulic pressure generating system is driven to generate electricity by the up and down motion of cylindrical float 1；Described drive mechanism 7 is steel
Anchor chain, it is adaptable to relatively deepwater regions.
The drinking water of cylindrical float 1 can Autonomous Control, when severe sea condition, the side of ballast water can be added by ballast pump 4
Formula realizes deeper drinking water, and then reduces buoyancy aid horizontal wave force under severe sea condition and motion response, to realize severe sea
The self-protection function of wave power device under condition.
The beneficial effects of the utility model: use the cylindrical float with transmission outer wall 2 as cylindrical float 1, be somebody's turn to do
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 outer wall 2
Drinking water h with whole device1Ratio h/h1The least.Under the restriction of drive mechanism 7, cylindrical float 1 mainly does with wave
Lower reciprocating motion, and then drive energy output system 8 to generate electricity.Under more severe sea condition, add ballast by ballast pump 4
The mode of water so that parameter h/h1Increase, so may result in the horizontal wave force suffered by float 1 and heaving response is the most obvious
Less, this is conducive to improving device survival ability under more severe sea condition.
Accompanying drawing explanation
Fig. 1 is float structure profile of the present utility model.
Fig. 2 is device form of the present utility model.
In figure: 1 cylindrical float；2 transmission outer walls；3 inner props；4 ballast pumps；5 tables；6 seabeds；7 drive mechanisms；
8 energy output systems.
Detailed description of the invention
With detailed description of the invention, this utility model is described in further detail below in conjunction with the accompanying drawings:
Have the version in breakwater function wave energy power station concurrently, mainly include cylindrical float (1), drive mechanism 7, energy
Output system 8；Cylindrical float 1 can move up and down under wave action, by drive mechanism 7 by cylindrical float 1
Kinetic energy passes to energy output system 8 and generates electricity；Cylindrical float 1 is the cylinder of upper bands transmission outer wall 2；Cylindrical float
1 is provided with ballast pump 4；In cylindrical float 1, add ballast water by ballast pump 4 and regulate eating of cylindrical float 1
Water.
Energy output system 8 is positioned at seabed, is made up of hydraulic pressure generating system.Drive mechanism 7 is steel anchor chain.Cylindrical floating
Son 1 is connected with energy output system 8 by drive mechanism 7, and cylindrical float 1 mainly does under the restriction effect of drive mechanism 7
Catenary motion.
The design parameter of embodiment is as follows:
The radius of buoyancy aid is 4 meters, and height is 6 meters, absorbs water 3 meters, and b/a is 0.5.Under conventional sea situation, parameter h/h1It is 0.25.
Said apparatus suitable depth of water 15-50 rice, wave period are the sea situation of 5-6 second.
As preferably, buoyancy aid uses steel processing and manufacturing.By reasonably design so that absorb water 4 meters, under conventional sea situation
Resonance can be realized, to realize the maximization of capacitation efficiency.This meets the practical situation that China coastal seas wave period is shorter.
As preferably, anchor chain uses steel cable.
As preferably, electricity generation system uses hydraulic pressure generating system, it is possible to achieve the steady output of electric energy.
As preferably, when period of wave more than the 7-8 second time, by ballast pump buoyancy aid to adding ballast water, buoyancy aid sinks 1.0
Rice.
According to the technical solution of the utility model, energy output system is used directly to obtain buoyancy aid kinetic energy and then be converted into electricity
Energy；When device is in severe sea condition, is realized the increase of float drinking water by ballast pump, and then reduce wave lotus suffered by buoyancy aid
Carry and motion response, and then increase device survival ability under severe sea condition.
