Embodiment
With reference to Figure of description 1 impeller-type sea wave power generation device, it comprises:
Get the energy unit, contain as the impeller 8 and the driving mechanism that is connected this impeller and power generating equipment of getting the energy member;
Platform, for described getting can the unit provide offshore platform, this platform front portion is plane of inclination 1, and the end in the plane of inclination is provided with guide plate 16, is provided with one or one group of described energy unit of getting that the impeller axis is identical at the end of this guide plate;
Wherein, described guide plate extends to directly over the described impeller; Described platform also is provided with the baffle plate that is positioned at described impeller rear side, so that the wave that pours in is formed the tangential water conservancy diversion of impeller.
About impeller, here needing clear and definite a bit is that the width of impeller blade is different from conventional impeller, cause is in the bigger generator of power, the force rate that drives its running needs is bigger, therefore needed driving force is also just bigger, and the width of blade and length just become a principal element of design inevitably so.Intensity because of the long very difficult assurance blade of length of blade, especially be difficult to guarantee the fixedly reliability of vanes fixed point, therefore, in this programme, preferably the factor of impeller width as overriding concern, and then width of blade just need take into full account spool impact that produced of sea beat blade to impeller.Further,, prevent the wide overhang that makes that its formation is long of impeller, the impeller broad ways can be divided into a plurality of impeller units bodies, and in the middle of each cell cube, a bearing is set in order to guarantee maintainability.
About guide plate, in principle its width will with the width basically identical of described blade, perhaps be wider than the width of blade, to obtain more liquid stream.
Saidly to being used for wave is formed the tangential water conservancy diversion of impeller for the ease of forming, described baffle plate is the plate of arc.This structure is not only simple, and the flow resistance that wave is formed is little.And arc surfaced guiding can also wave become on the way described impeller shaft to current, be convenient to utilize to greatest extent the kinetic energy of wave.
In addition, the baffle plate of arc has reduced the impact of wave in the baffle plate normal direction than straight baffle plate, has not only reduced wave directly to the impact of platform, can also reduce the kinetic energy rejection of wave.
In order better the wave that pours in to be carried out along leading, described guide plate is connected with the arc transition of described plane of inclination, and this guide plate transverse section is a S shape, it is the S shape that the side of a stretching is fallen that certain above-mentioned S shape is explained more specifically, preferably its terminal tangent line is parallel at the tangent line at this place with impeller, perhaps becomes the angle less than 5 degree.
Further, in order better wave to be carried out suitable leading, the terminal part of described guide plate is the preceding arc guide part 15 of a concave surface towards impeller.
Relate to the guiding to wave, also need a bit here, the unrestrained face that is subjected to that is exactly blade should comprise that at least form is the part of concave surface, and this part is preferably in impeller outside radially.More specifically, described blade should be concave surface towards the cambered surface of wave (cylindrical structure, setting forth with cambered surface mainly is according to the top transverse section of mentioning) herein or have the blade of other curved-surface structures.Certainly, plate shaped blade also can use, and just the blade shape of being explained before more helps getting energy.
Nature, said platform is big more, helps the stability of platform more, and it is also just meaningful in actual applications to get the energy cell array, and therefore, described getting can be provided with a plurality of or many groups along the surge direction in the unit, last baffle plate is provided with current plane of inclination of getting the energy unit, and all plane of inclination coplanars.This structure can utilize different waves high fully, do not make higher wave that a backflow rush to plane of inclination after be arranged with a bigger plane of inclination and do not resemble in the described scheme of background technique, a plurality of baffle plates that this programme adopts step to be provided with, make being utilized of higher wave part, partly can be utilized the unit by follow-up getting by the first order.Nature, in order to reduce the complexity of system, said step had better not be above 5 grades, so in the end one-level need be provided with a higher baffle plate, and certainly, excessive wave is not within the consideration of this programme, prevent that the impact force that produces is excessive, damage platform, such as the fierce wave that surpasses 6 meters.
For a platform stably is provided, the floating device of the master of described platform comprises the latent buoyancy aid 5 that is arranged at these platform front and back, should dive is connected by rigid support 4 between buoyancy aid and described platform, and the substrate 3 that makes the described platform that is tangential to described impeller upside is between wave crest and trough; Described latent buoyancy aid is fixed in the seabed by chain 6 or is connected on the seabed counterweight 7.Buoyancy aid is subjected to the influence of surface seawater smaller owing to dive, and therefore, described platform is subjected to the influence of wave smaller comparatively speaking, and its height across the sea is stable basically.
For the application of wave, based on this programme, said impeller type power generating equipment also can be installed on the bank, and so obvious a bit is in the process of gushing on the ocean, is subjected to the energy that stop of getting the energy unit at different levels and greatly reduces, and can play the effect of breakwater.Certainly, above the rigid support mentioned also can be fixed on the seabed, in the neritic area operation, and this rigid support can make telescopic structure, be convenient to adjust get can the unit upper-lower position.
It is also conceivable that in this programme that platform self can produce certain buoyancy, the left and right sides plate of so described substrate, the plate that constitutes described plane of inclination and described guide plate and configuration constitutes the preceding floating chamber 2 of water tightness; And be provided with the back buoyancy aid 10 of volume greater than this preceding floating chamber in described platform end.The state that suitable buoyancy aid helps adjusting platform is set, and the buoyancy aid under the water-stop state can also be as the installing space of power generating equipment on platform.
Further, also can buoyancy aid be set at the middle part of platform, such as, be arranged in the guide plate at platform middle part, the baffle plate 12 adjacent, and dispose left baffle and a base plate just can make up watertight compartment with this guide plate.In addition, said base plate can be the housing of impeller, can simplified structure.
Consider the influence of tide bulge and fall in addition, described chain is used to adjust the degree of depth of latent buoyancy aid by the hoisting equipment control that is arranged in the described latent buoyancy aid.
For getting the energy unit, described driving mechanism is arranged in the cavity of water-stop, and the power input shaft of this driving mechanism is provided with rotation axis seal.The anticorrosion ratio of simple impeller is easier to handle, so driving mechanism anticorrosion relatively difficult, therefore, driving mechanism is arranged in the cavity of water-stop, be convenient to form protection, and also be beneficial to the lubricated of driving mechanism.
Because the unstability of wave, described driving mechanism is connected with the free wheel device that is connected to of the axle of described impeller, makes the driving mechanism input shaft rotational speed can not be lower than the rotating speed of impeller.
