Description
Technical field
The present invention relates to offshore wind farm technical field more particularly to a kind of perpendicular axis type water with separate type speedup conflux plate
Turbine.
Background technique
Energy by ocean current refers to the kinetic energy that seawater is contained in bottom horizontal flow sheet, is one of regenerable marine energy, general next
Say that water velocity is greater than in the seabed water channel or straits of 2 meter per seconds and the regular seawater flowing as caused by tide is regional
Interior energy by ocean current resource all has the value that can be developed and used.Due to similar to the principle of wind-power electricity generation, current most of developments
In ocean current energy generator also followed the design of wind energy conversion system, two class of horizontal axial type and perpendicular axis type, perpendicular axis type can be divided into
Energy by ocean current device (hydraulic turbine) the mountable even bank more than the water surface of generating equipment, to substantially reduce seawater pair
The erosion damage of these critical components thereby reduces the maintenance cost of system.In addition, the perpendicular axis type energy by ocean current hydraulic turbine is met
Flow area is rectangle to which the restriction during installation by depth of water height is smaller, therefore is more suitable for flow velocity than horizontal shaft device
Greatly, in the shallower runner of the depth of water.Although the vertical axis energy by ocean current hydraulic turbine has many excellent compared with horizontal shaft device (as shown in Figure 1)
Point, but the energy conversion efficiency of this hydraulic turbine is lower, is still generally lower than horizontal axial type device so far, and improve perpendicular axis type
The energy conversion efficiency of the energy by ocean current hydraulic turbine is the key that this power generator is made to obtain broader applications.
The method for improving the perpendicular axis type hydraulic turbine at present can be divided into active and two class of passive type, and active can be in water wheels
On rotor blade by jet stream, vibration thin slice or blow, the method for air-breathing is by the input of local energy, improve blade surface
Flow regime improves the acting performance of blade, but such methods require the expenditure of energy and mechanism is complicated, are not suitable for harsh and multiple
Miscellaneous changeable marine environment.Passive type method installs attached small structure such as rib, cylinder, optimization blade geometric shape additional on blade
Consumption energy is not needed Deng, such methods, therefore structure is simple without additional adding set or system.
But improve blade acting performance currently with attached small structure such as rib, cylinder, optimization blade geometric shape etc.
Passive type method needs directly installed additional in rotor blade surface, off design performance in practical applications is poor, cannot
It is adjusted correspondingly according to the variation of mainstream operating condition, can be increased instead under certain operating conditions because changing the geometric shape of blade
Big flow resistance reduces the hydrodynamic characterisitic of turbine blade.In addition, traditional lift vertical shaft turbine blade is rotating
During one week when blade rotates to -360 ° of lower half period i.e. 180 ° (as shown in Figure 2), blade often operates in upper half
In the tail area that interim blade and rotary shaft rear portion generate (as shown in Figure 3), flow velocity is reduced, the decline of blade capacitation efficiency, so that
Rotor efficiently do work region reduction.

Few two pieces of speedup offices can do setting in vertical Zhou Shi hydroturbine rotor downstream, and flow velocity can be improved when plate by enabling flow through speedup office,
Improve the shortcomings that causing its performance of doing work to decline because of flow velocity reduction when blade rotates to the later half period.
