Description
Technical field
The present invention relates to marine tidal-current energy power field more particularly to a kind of trunnion axis floating marine tidal-current energies of single point mooring's form
Power generator.
Background technique
Ocean Tidal Current Energy is one kind of regenerable marine energy, can will be contained in sea tide by energy conversion devices
Huge kinetic energy be converted into electric energy and be used.Compared to other renewable energy, Ocean Tidal Current Energy has many advantages, such as, collection
In be embodied in: energy density is big, predictability is strong, stable load and rich reserves.China possesses the sea up to 1.8 ten thousand kilometers
Water front, the marine territory more than 3,000,000 square kilometres, the marine tidal-current energy theory generated output that is averaged is more than 1.3 ten thousand megawatts.According to statistics,
In China, the development prospect that 130 water channels have marine tidal-current energy power generation is had more than, especially in Zhoushan Region, Yi Jibo
Straits etc., tidal current speed up to 3.0m/s or more, energy density up to 15kW/m2, have good utility value and
Development prospect.
The capacitation mode of Ocean Tidal Current Energy power generator is varied, and most devices pass through rotating vane for fluid
Kinetic energy is converted into electric energy, also have through flapping foil, and the modes such as vortex-induced vibration obtain energy.Pass through the trend of the hydraulic turbine or energy
Energy power generator can formally be divided into horizontal axial type and perpendicular axis type.The major defect of horizontal shaft water-turbine is weaker to open certainly
Kinetic force, biggish torque fluctuations and lower energy conversion efficiency in a swing circle.From the point of view of fixed form, tide
Stream energy power generator can be divided into fixed and floatation type.Fixed tidal current energy generating equipment relies on self gravity, or passes through conduit
The support construction of the forms such as frame is fixed on seabed, whole submerged in water.Although not influenced by sea condition, installation, maintenance
Higher cost, and it is irremovable.
Due to leaning near Sea Bottom, tidal current speed slows down, and limits the performance of turbine characteristics.Floating water turbine is fixed on drift
On float carrier, it is fixed on sea bed by anchoring system.It is designed using floating structure, to depth of water wide adaptation range, to seabed
Shape does not have particular/special requirement, installs, is easy to maintain.Since surface current speed is fast, it is easily obtained more energy.
For marine tidal-current energy device, its cost of electricity-generating is apparently higher than offshore wind energy etc. at present.Current higher cost master
If because its load characteristic it is not clear, from structure be designed into later maintenance in order to ensure structure safety, use compared with
Big safe clearance causes the cost of electricity-generating of marine tidal-current energy device high.
Therefore, we are it is necessary to improve such a structure, to overcome drawbacks described above.
Summary of the invention
The object of the present invention is to provide a kind of trunnion axis floating tidal current energy generating equipments of single point mooring's form, utilize weathercock
Effect reduces resistance, and independently to positive trend, the Area of Water Plan of reduction is to reduce seaway load.
Above-mentioned technical purpose of the invention is that used following technical scheme is realized: a kind of trunnion axis of single point mooring's form
Floating tidal current energy generating equipment including floating carrier, is connected to the impeller unit of floating carrier lower end surface, and the floating carrier connects
It is connected to single point mooring unit, the floating carrier is provided with the orientation rudder for being oriented to floating carrier.
The further setting of the present invention are as follows: the floating carrier include floatable body, two be divided into the floatable body
Balance floating body, the balance floating body protrudes from the floatable body lower end surface.
The further setting of the present invention are as follows: the impeller unit is set as two groups, and two groups of impeller units are all set in described
Floating body is balanced, and the impeller of two groups of impeller units is in opposite rotation.
In conclusion the invention has the following advantages:
1) because using new single site mooring, it can use weathercock effect and reduce resistance, independently to positive trend.
2) use binary airflow design, the Area of Water Plan of reduction to reduce seaway load, provide buoyancy and
Biggish restoring moment.
3) three leaf rotary blade of trunnion axis is used, by the arrangement turned, counteracting rolling tilting moment side by side.
4) by the way that orientation steering engine structure is arranged in tail flow field, has on the one hand upset flow field, reduced the coverage of wake flow, one
Aspect generates autonomous control torque, cooperates single point mooring system, can be independently to positive direction of tide.Steering with tradition setting fills
It sets and compares, structure greatly abbreviation is not necessarily to active control, saves cost.
