Technical field
The utility model relates to a kind of electricity generating device, relates in particular to a kind of combined power generation device that simultaneously utilizes wind energy on the sea and marine tidal-current energy to generate electricity.
Background technique
Sustainable development along with World Economics, the total amount consumed of the energy also grows with each passing day, wherein fossil energy has accounted for again the large portion of energy-output ratio, various pollutions in fossil energy combustion process, have been produced, thereby produced series of environmental problems: the Global climate change causing as a large amount of greenhouse gas emissions, the water pollution problems that pollutant emission causes, the oil accident that offshore oil development causes etc.In the face of these stern challenges, people invest those free of contamination novel energies eye gradually.Ocean energy is exactly a kind of so pollution-free, renewable, appreciable novel energy of reserves, has also therefore been subject to the extensive concern of international community.
Regenerable marine energy electricity generating device has been carried out a large amount of research work in recent years, coastal waters wind generating technology comparative maturity wherein, and wave energy and marine tidal-current energy generation technology also make great progress.But current most research work is all to using single coastal waters renewable energy sources as research object, in actual development process, utilize separately a kind of maritime renewable energy to tend to run into the problem that generating efficiency is low, cost of electricity-generating is high, thereby delayed the process of commercial development.If Oversea wind power generation is only the wind resource that has utilized ocean, when in wind speed less season, the output power of wind-driven generator, just far below the rated power of its setting, causes the waste of investment.Wind-power electricity generation causes electric energy production not enough sometimes, electric energy production is superfluous sometimes, add wind-force and change very difficult prediction, the shakiness of output power also can have a negative impact to grid stability, cause the difficulty that networks, many marine wind electric fields that build up are faced with and have generated the predicament that electricity but cannot network at present, therefore simple wind power plant easily causes the huge waste of production capacity and investment.Have in recent years and also have the clear wave energy in shallow sea, the electricity generating device of marine tidal-current energy complementation of being applicable to of human hair, what it adopted is the ocean wave generator of floating type, shortcoming is floating type sea wave generator machine when work, the space in air and seawater alternate all the time, and the high cost that causes of anticorrosion rank is higher.And the residing work under bad environment of electricity generating device, while moving in ocean, when storm, typhoon are attacked, floating electricity generating device is very easy to damage.
How to design the firm supporting of a kind of energy, and the combined power generation device that makes full use of wind energy and marine tidal-current energy, raising rate of return on investment is the direction that person skilled will be studied for this reason.
Summary of the invention
Technical problem to be solved in the utility model is for above-mentioned prior art present situation, to provide a kind of can make full use of the wind energy marine tidal-current energy combined power generation device that wind energy and marine tidal-current energy generate electricity, it can make up the unstability of wind-power electricity generation, promotes the generating efficiency of electricity generating device.
The utility model solves the problems of the technologies described above adopted technological scheme: a kind of wind energy marine tidal-current energy combined power generation device, comprise and plug the column that is fixed on seabed, the top of column is provided with wind-driven generator, it is characterized in that: the bottom of described column is provided with tidal current generator, the power output end of described wind-driven generator and the power output end of described tidal current generator are transported to the booster stations that are positioned at land by submarine cable.
Above-mentioned marine tidal-current energy generator is vertical pivot hydraulic turbine generator, and this vertical pivot hydraulic turbine generator is set on column.Utilize the mechanical energy that the device such as blade of fluctuation time of tide water impact water turbine produces to change into electric energy, current are perpendicular to running shaft, and the advantage of vertical pivot water turbine is that to flow to adaptability good, and each can self-starting during to incoming flow, and capacitation coefficient is high.
The relative column upper-lower position of above-mentioned vertical pivot hydraulic turbine generator can regulate.According to actual streamflow regime, determine the diverse location that is arranged on blower fan like this, to catch larger flow velocity, also facilitate maintenance and the maintenance in later stage.
Above-mentioned seabed is inserted with three pile bases, and this three piles base is distributed on column periphery and is angular position and arranges, is connected, and by attachment post, links together between adjacent two pile foundations between every pile base and column by the supporting post being obliquely installed.Three pile bases form triangular shape and support, between pile foundation, by attachment post, link together, structure is more firm, between pile foundation and column, by the supporting post being obliquely installed, be connected and allow column and the firm combination of pile foundation, by interconnecting with column between pile foundation, supporting post, attachment post three, make column firm be fixed on seabed, effect that can storm resisting stream, guarantees the steadiness of this electricity generating device.
Compared with prior art, the utility model has the advantage of: 1. improve marine site utilization efficiency, wind-driven generator and marine tidal-current energy generator are combined on same column, than building respectively marine wind electric field or marine tidal-current energy power plant, take less oceanic area; 2. improve generating efficiency, the energy flux density of marine tidal-current energy is high, and in the situation that speed is identical, the generated energy of tidal power generating can reach 800 times of left and right of wind-power electricity generation, adopts this combined power generation device can make full use of marine wind energy and marine tidal-current energy; 3. improve the stability of generating, marine tidal-current energy causes by the tide-generating force of the sun and the moon, and energy source is stable, can make up the shortcoming of wind energy on the sea poor stability, convenient networking; 4. cost-saving, cost of electricity-generating is too high is the bottleneck that restriction wind energy on the sea, marine tidal-current energy or other renewable energy sourcess develop, and two kinds of electricity generating devices of the utility model share a set of generating, transmission system, can effectively reduce development cost.
