The invention belongs to a kind of Novel floating wave energy generating set.This device adopts the float of particular design, and float is made by flexible material and rigid material, by the buoyancy of control switch valve regulation float.There is slide bar to pass in the middle of float; Lower end driving-energy conversion equipment converts wave energy to electric energy.Universal hinge is arranged at the slide bar bottom, is connected with underwater appendage by adopting universal hinge.Underwater appendage is sunken to the seabed, and surrounding is with anchor and anchor chain, with the ground anchoring.
Its basic functional principle is: under wave action, float is under the constraint of slide bar, move along slide bar, when capturing wave energy, drive slide bar and tilt to the wave downstream, that has realized device automatically can function to wave, and no matter wave is from any direction, can meet ripple with optimum posture, winding, the wear problem of having avoided cable to cause because of the wave energy apparatus motion.
The present invention compared with prior art has following advantage:
(1) improve the wave energy capture efficiency
The wave energy apparatus conversion efficiency is to weigh the standard of this device performance, has determined cost of electricity-generating.Bottom the slide bar that has, its advantage is:
1, by suppressing the motion of the vertical slide bar of float, increase float and move along slide bar, improve the wave energy capture efficiency:
From studies show that, under the depth wave effect, the float optimal movement angle under the slide bar restriction is near 60 °; And under the ripple effect of Finite Water Depth, the optimal movement angle of float diminishes, generally 45 ° of left and right.Existing wave energy apparatus power float (Power Buoy) wave energy apparatus leans on the slide bar restriction float that welds together with underwater appendage, and its slide bar angle is often bigger than normal than best angle, reaches 80 ° of left and right.And the slide bar of device of the present invention is connected with underwater appendage by universal joint, and is larger than the slide bar angle of inclination of power float, can reach optimum angle of incidence.
In addition, underwater appendage of the present invention is seated in the seabed, and during the float motion, underwater appendage moves hardly, and float is more effective to the energy conversion system acting; And all floating type waving energy device such as power float etc. at present, all because swimming in water, when float moves, motion a certain amount of, that synchronize with float that underwater appendage also exists, float to energy conversion system acting therefore give a discount.
2, automatically to wave
Wave is subjected to the influence of topography by becoming humorously, can reflect, diffraction and change direction.Because China marine site is in the monsoon region, wind is obvious with seasonal variations.In autumn, winter, three seasons of spring, predominant wind have the southeast, east, northeast, north etc. to; Summer predominant wind have southwest, south, the southeast etc. to.The wave that different wind directions cause also have different waves to.Therefore, wave energy apparatus need to be fit to any wave to, otherwise, with reducing device and capture the ability of wave energy, even cause device to be destroyed by wave.
Apparatus of the present invention adopt universal hinge to wave, can adapt to different waves to.With wave energy apparatus ratios such as sea snake (Pelamis), canard (Duck), ripple dragon (Wave Dragon) and power floats (Power Buoy), have simple in structure, reliable, be easy to the advantage such as installation input.
(2) reliability
1, prevent cable breakage
The electric power that floating type waving energy device produces by submarine cable, is carried disembarkation.When vertical in wave of device swings and during horizontal motion, drag cable often, easily cause cable in the seabed wearing and tearing even break; In addition, device turns when wave direction changes, and also might cause cable be wound around by anchor chain and rupture.The degree of risk of cable bad depends on distance, the angle of change and the distribution of anchor chain of device drift.
Sea snake (Pelamis), canard (Duck), ripple dragon wave energy apparatus such as (Wave Dragon) adopted the scheme of single point mooring adapt to different waves to, make wave energy apparatus along centered by anchor, the projected length take anchor chain on horizontal plane is the circular movement of radius.Such device position movement distance when wind vector reaches hundreds of rice, and steering angle can be 360 °.For fear of excessive displacement distance and corner occurring, ripple dragon device has adopted stern anchor, but so, has limited again automatically to unrestrained ability.
Power float (Power Buoy) wave energy apparatus adopts 3 anchors, 3 chain moorings, retrains preferably the horizontal motion of wave energy apparatus and turns to very littlely, preferably resolves cable and is wound around problem by anchor chain; Its float design is circular, the directive wave to adapt to.However, under stormy waves, wave energy apparatus still has the displacement distance of tens of meters.
Main difference of the present invention is, the energy conversion device of wave energy apparatus is arranged on underwater appendage, and underwater appendage directly is seated in the seabed, and by the anchor tension, avoids horizontal motion.The cable of wave energy apparatus can be along the underwater appendage edge, and the cable wearing and tearing are avoided in the nonmotile seabed that falls into.This structure has also been avoided cable winding fully, has effectively reduced the risk of cable breakage, is better than all floating type waving energy devices at present.
2, reduce the anchor chain pulling force
The mooring force of wave energy apparatus is mainly derived from the second order power of wave.Because frequency approaches, device motion by a relatively large margin occurs under second order difference frequency action of wave force, and the anchor chain that easily causes relaxing is strained suddenly, causes very large anchor chain power, easily breaks anchor chain, or causes dragging of anchor.
Wave energy apparatus of the present invention is seated the seabed because of the bottom, surrounding is used again anchor chain and submarine anchoring, effectively retrained device to the response of Second Order, reduced the anchor chain pulling force that the device motion causes, aspect the anchor chain power much smaller than existing floating type waving energy device.
3, reduce structure stress
Slide bar of the present invention is articulated on underwater appendage, rather than is welded on underwater appendage, and flexural stress suffered on slide bar and underwater appendage is very little, has effectively reduced physical dimension.
(3) throw in recovery and safeguard simple possible
It is huge that floating type waving energy device is thrown in cost, in case throw in just modifier state and input place easily.Device for a long time is worked under abominable ocean environment, will safeguard unavoidably, and light maintenance or can carry out under real sea conditions, overhaul need be reclaimed afterwards and be carried out in factory or harbour.The realization of throwing in, reclaiming is the problem that design wave energy device must be considered, otherwise will strengthen construction and maintenance cost.
Oyster (oyster) wave energy apparatus is the hinged buoyancy pendulum in lower end, hinge and the supporting structure thereof of device must be fixed on the sea bed of the 10-15 rice depth of water, the pendulum plate structure of acting only has fraction to expose the sea, this means of fixation is thrown in recovery to device and has been brought great difficulty of construction, all below the sea, maintenance work also is difficult to launch due to most of mechanism.
Power float wave energy apparatus is held with 3 anchor chains on its underwater appendage, during recovery, floats, to untie the anchor chain difficulty larger.
The underwater appendage buoyancy of apparatus of the present invention can be regulated, and in transit, underwater appendage, column slide bar and float all have self-buoyancy, and device is bubbled through the water column, and is convenient to pull transportation; During input, the gas in underwater appendage is bled off, make its loss of buoyance, sink down into the seabed; The anchor shape structure of underwater appendage bottom will produce grip, limit its horizontal motion; Underwater appendage gravity makes it to be difficult to move upward as the used time at float, and anchor chain and anchor further strengthen its stability; When reclaiming, by to the underwater appendage inflation, drain its inner water, increase its buoyancy, make device lower end floating, can carry out marine checking machine simple maintenance; Untie anchor chain, device can be towed back to factory or harbour, carry out relatively large inspection and maintenance.
(4) structure and anchoring system are more cheap
The present invention adopts the slide bar of tubulose, the flexible float that includes steel structure, the underwater appendage with buoyancy tank, simple anchor and anchor chain, ensureing efficiently the capturing on basis with reliability of wave energy, also have the advantages such as the construction of being easy to, input and maintenance, cost and maintenance are cheap, have the stronger market competitiveness.
Apparatus of the present invention and above-mentioned wave energy apparatus compare, and apparatus structure is simple, only adopt common flexible rubber (float) and steel (underwater appendage, slide bar), and price is low, and is durable, can survive in ocean environment for a long time.Float directly is connected with the hydraulic pressure converting system, and energy transfer process is simple, and reliability is high, energy loss is low.Only install buoys float across the sea, size is little, and environmetal impact is little.The device mooring system is comprised of anchor and anchor chain, and only in the getting final product of seabed, between mooring point, without specific (special) requirements, whole anchoring system link is succinct, easy to make quick, cheap with the underwater appendage mooring for need.
Generally speaking, compare with other wave energy apparatus in the past, the present invention has the following advantages: 1. and the movement locus of slide bar constraint float, improved the capture efficiency of device; 2. device has automatically wave, automatically regulates the characteristics of floading condition, adapts to the wave of different sizes and direction, is adapted at the marine site work of different water depth, and the year-round operation cycle is long; 3. submarine cable is drawn from universal hinge symmetrical line, has avoided the winding problem of cable, has guaranteed the safety of electric power transfer; 4. the device oil hydraulic cylinder directly is connected with float, reduces energy intermediate transfer process, has improved structural reliability; 5. anchoring system safety is succinct, with low cost; 6. carry the underwater appendage of buoyancy force adjustable, throw in and reclaim facility, housekeeping operation is simple, and expense is cheap.
