Description
Technical field
The invention belongs to technical field of power generation, more particularly to a kind of generator.
Background technique
Oversea wind resources supplIes are better than land, and Oversea wind power generation has unique advantage, and development causes various countries
The great attention of government.To reduce manufacture, transport, the average unit costs such as installation and maintenance, then reduction degree electricity cost and raising unit
Area generated energy, marine windmill single-machine capacity and blade dimensions sustained, stable growth.Currently, rated power generally 1MW~
5MW, the wind energy conversion system of energy successful operation maximum rated power 6MW is in the success on-hook of the ground such as the U.S., Europe and China.And specified function
Rate 10MW (root diameter 144m) the even large scale wind power machine of rated power 20MW (diameter 240m) are just under study for action.
Usual pneumatic equipment bladess cost only accounts for the 10%~15% of entire wind turbine system cost, merely reduces blade system
Cause this very limited to the effect of reduction degree electricity cost.If there can be a kind of method to reduce load, the very big of cost will be brought
It reduces, this is because load relation is to several big important components of wind energy conversion system, such as pylon, transmission mechanism.The control of active control theory
The more advanced technology of load is exactly whole variable pitch and independent pitch.Whole variable pitch is mainly used for regulation power, assists control load,
And independent pitch refers to that wind energy conversion system wind regime according to suffered by each blade independently changes propeller pitch angle, can preferably improve load.But
As blade dimensions increase, flow condition, which is opened up along blade to the inhomogeneities of distribution, to be enhanced, and variable pitch strategy gradually shows following
Insufficient: entire blade synchronization transfers the fluctuation that cannot effectively control local load, and uneconomical, and inertia is big, easily leads to variable pitch dress
It sets and excessively uses.
Summary of the invention
For the above technical problems, the present invention provides a kind of generator, it uses vertical cabin, makes entire cabin
Characteristics of compact layout, anti-typhoon capacity are strong.
The purpose of the present invention is achieved through the following technical solutions:
A kind of generator of the present invention, including can independent pitch wind wheel, change gear case, closed vertical cabin, power control cabinet,
Generator, yaw device, the wind wheel are connect by change gear case with generator in vertical cabin, and vertical cabin is placed in pylon
Yaw device is arranged between vertical cabin and pylon in top.
Further, gearbox is connected between the change gear case and generator.
Further, the change gear case is deflecting step-up gear.
Further, the wind wheel blade is two panels or three pieces, is uniformly arranged along circumference of hub, in every blade away from blade tip
Arrange that flank, the flank width are the 1/10-1/7 of width of blade at 5-15%, length is the 1/6-1/8 of length of blade.
Further, the change gear case and generator are using concentration cooler.
The invention has the benefit that
1. the present invention uses vertical cabin relative to current marine windmill, keep entire Arrangement of Engine-room compact, and cancel
Engine room cover；Anti-typhoon capacity is strong.
2. can effectively slow down the load of pneumatic equipment bladess and pylon using independent pitch and wind wheel shoulder, and mention
The life and reliability of high wind energy conversion system.
Detailed description of the invention
Fig. 1 is the structural schematic diagram that the present invention uses two blades.
Fig. 2 is the structural schematic diagram that the present invention uses three blades.
In figure: 1. wind wheels, 2. change gear casees, 3. gearboxes, 4. generators, 5. vertical cabins, 6. yaw devices, 7. towers
Frame, 8. flanks, 9. deflecting step-up gears.
Specific embodiment
Below by embodiment and attached drawing, the invention will be further described.
Embodiment 1: as shown in Figure 1, a kind of wind-driven generator of the present invention, including can independent pitch wind wheel 1, change gear case
2, closed vertical cabin 5, power control cabinet, generator 4, yaw device 6, the wind wheel 1 pass through change gear case 2 and vertical cabin
Generator 4 connects in 5, and vertical cabin 5 is placed in 7 top of pylon, and yaw device 6 is arranged between vertical cabin 5 and pylon 7 and (uses
Existing structure).
Gearbox is connected between the change gear case and generator.
The wind wheel blade is two panels, is uniformly arranged along circumference of hub, in every blade away from arrangement side at blade tip 5-15%
The wing, the flank width are the 1/10-1/7 of width of blade, and length is the 1/6-1/8 of length of blade.The change gear case and
Generator is using concentration cooler.
Embodiment 2: this example unlike the first embodiment: change gear case described in this example be deflecting step-up gear；Institute
Stating wind wheel blade is three pieces.
