Technical field
The present invention relates to field of new energy utilization, provide a kind of structure improving float-type wave power device survival ability.
Background technology
In the world today, as the disposable energy is petered out the aggravation with environmental pollution, people are more and more sight
The development and utilization for having invested clean regenerative resource.Wave energy is the important component of regenerable marine energy, is
A kind of clean regenerative resource.
Wave energy generating set is varied, but there is no too many wave-energy power generation project inputs to transport to commercialization
Row.Years Of Service of the wave energy apparatus under the conventional sea situation and its fatigue problem of caused structure becomes under wave load
The big bottleneck for hindering wave energy to develop and use；In addition, survival ability of the wave power device under severe sea condition hinders its business again
Change the another big obstacle of operation.This will largely decide the cost input of wave-energy power generation engineering.Therefore, wave energy is reduced
The inessential wave load of device and the survival ability under its severe sea condition is improved, is the key that wave energy research on utilization.Transmission knot
Structure is a kind of works common in ocean engineering, is widely used in the structures such as breakwater, harbour pile.If can pass through
It efficiently uses hollow structure object and traditional wave power device is reasonably transformed, to reduce the inessential wave force and motor imagination width of device
Value, you can improve wave power device survival ability.
Invention content
The present invention is directed to deficiency in the prior art, it is proposed that a kind of dress improving float-type wave power device survival ability
It sets.
Technical scheme of the present invention：
A kind of structure improving float-type wave power device survival ability, which includes cylindrical float 1, transmission mechanism 7
With energy output system 8；1 external wall of upper portion of cylindrical float is transmission outer wall 2, and inner prop 3 is carried in transmission outer wall 2, interior
Column 3 is integrated convex shape with 1 lower part of cylindrical float, has gap before inner prop 3 and transmission outer wall 2；1 lower part of cylindrical float
Outer wall is equipped with ballast pump 4, autonomous load or unload ballast water；The energy output system 8 is hydraulic pressure generating system, Gu
Due to seabed 6, hydraulic pressure generating system power generation is driven by the up and down motion of cylindrical float 1；The transmission mechanism 7 is steel
Anchor chain is suitable for compared with deepwater regions.
The drinking water of cylindrical float 1 can autonomous control can pass through the side of ballast pump 4 plus ballast water when severe sea condition
Formula realizes deeper drinking water, and then reduces horizontal wave force and motor imagination of the floating body under severe sea condition, to realize severe sea
The self-protection function of wave power device under condition.
Beneficial effects of the present invention：Using the cylindrical float with transmission outer wall 2 as cylindrical float 1, the type knot
Structure object simple shape, convenient for manufacture.Under conventional sea situation, the shallower draft of cylindrical float 1, the drinking water h of transmission outer wall 2 with it is whole
The drinking water h of a device1The ratio between h/h1Also smaller.Under the limitation of transmission mechanism 7, cylindrical float 1 mainly does past up and down with wave
Multiple movement, and then driving energy output system 8 generates electricity.Under more severe sea condition, ballast water is added by ballast pump 4
Mode so that parameter h/h1Increase, can cause in this way horizontal wave force suffered by float 1 and heaving response obviously compared with
Small, this is conducive to improve survival ability of the device under more severe sea condition.
Description of the drawings
Fig. 1 is the float structure sectional view of the present invention.
Fig. 2 is the device of the invention form.
In figure：1 cylindrical float；2 transmission outer walls；3 inner props；4 ballast pumps；5 tables；
6 seabeds；7 transmission mechanisms；8 energy output systems.
Specific implementation mode
Present invention is further described in detail with specific implementation mode below in conjunction with the accompanying drawings：
The structure type in breakwater function wave energy power station is had both, includes mainly cylindrical float (1), transmission 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 cylinder of the top with transmission outer wall 2；Cylindrical float
1 is equipped with ballast pump 4；Ballast water is added to adjust eating for cylindrical float 1 into cylindrical float 1 by ballast pump 4
Water.
Energy output system 8 is located at seabed, is made of hydraulic pressure generating system.Transmission mechanism 7 is steel anchor chain.Cylinder is floating
Son 1 is connected by transmission mechanism 7 with energy output system 8, and cylindrical float 1 is mainly done under the restriction effect of transmission mechanism 7
Catenary motion.
The design parameter of embodiment is as follows：
The radius of floating body is 4 meters, is highly 6 meters, absorbs water 3 meters, b/a 0.5.Under conventional sea situation, parameter h/h1It is 0.25.
Above-mentioned apparatus is suitable for 15-50 meters of the depth of water, the sea situation that wave period is 5-6 seconds.
Preferably, floating body is fabricated using steel.By reasonably designing so that 4 meters of drinking water, under conventional sea situation
It may be implemented to resonate, to realize the maximization of capacitation efficiency.This meets the shorter actual conditions of China coastal seas wave period.
Preferably, anchor chain uses steel cable.
Preferably, electricity generation system uses hydraulic pressure generating system, the steady output of electric energy may be implemented.
Preferably, when wave period be more than 7-8 second when, by ballast pump floating body to be added ballast water, floating body sinking 1.0
Rice.
