Abstract
The utility model provides an automatic become oar wind wheel structure, including a wheel hub and three sets of blade subassemblies, three sets of blade subassemblies are installed respectively to the wheel hub circumference, the blade subassembly includes blade, wheel hub axle and a plurality of spring damping ware, blade and wheel hub axle coaxial coupling, and a plurality of spring damping wares are still installed to blade and wheel hub axle, wheel hub axle fixed connection in the wheel hub and the three sets of blade subassemblies. The connected mode of wheel hub and wheel hub axle can be for bolted connection. Rotation axis on the blade is located blade leading edge one side. The utility model discloses a self -adaptation becomes the oar structure, does not have extra power, and is more energy -conserving, the utility model discloses simple structure, cost are lower, are applicable to small wind turbine unit power control mode.
Description
Technical field
This utility model relates to wind-driven generator group wind-wheel and becomes oar technical field, is specially a kind of automatic pitch-adjusting wind wheel structure.
Background technology
The development prospect of wind power industry is very wide, greatly develops the emphasis that wind-powered electricity generation is China's new forms of energy strategy.While improving constantly wind power generating set reliability, reduce the developing direction that cost is all wind power plants.Wind turbine pitch system, as one of the core component of wind-power electricity generation, improves reliability, reduces the emphasis that cost is also its technological innovation.
When existing small power generation unit is more than rated wind speed, usually by the function of crosswind or stall or change oar realization restriction power, but its structure is all more complicated, and cost is also of a relatively high.
Utility model content
Utility model purpose: provide a kind of automatic pitch-adjusting wind wheel structure, to solve above-mentioned technical problem.
Technical scheme: this utility model is achieved through the following technical solutions:
A kind of automatic pitch-adjusting wind wheel structure, is separately installed with three set blade assemblies including described circumference of hub；It is coaxially connected that described blade assembly includes blade, hub spindle and some spring-dampers, blade and hub spindle, and blade and hub spindle are also equipped with some spring-dampers；
The fixing connection of hub spindle in described wheel hub and three set blade assemblies.
Described wheel hub can be connected for bolt with the connected mode of hub spindle.
Rotating shaft on described blade is positioned at blade inlet edge side.
Beneficial effect
Technique scheme is adopted to provide the benefit that:
1. this utility model adopts self adaptation variation paddle structure, it does not have extra power, more energy-conservation；
2. this utility model simple in construction, less costly applicable small unit strong wind time power control mode.
Accompanying drawing explanation
Fig. 1 is: this utility model overall structure schematic diagram；
Fig. 2 is: this utility model blade component structure schematic diagram；
Fig. 3 is: this utility model blade assembly explosive view；
1. wheel hub in figure, 2. blade assembly, 21. blades, 22. hub spindles, 23. spring-dampers.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described further；
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of automatic pitch-adjusting wind wheel structure that this utility model provides, including a wheel hub 1 and three set blade assemblies 2, described wheel hub 1 circumference is separately installed with three set blade assemblies 2；It is coaxially connected that described blade assembly 2 includes blade 21, hub spindle 22 and some spring-dampers 23, blade 21 and hub spindle 22, and blade 21 and hub spindle 22 are also equipped with some spring-dampers 23；
Described wheel hub 1 is fixing with the hub spindle 22 in three set blade assemblies 2 to be connected.
Described wheel hub 1 can be connected for bolt with the connected mode of hub spindle 22.
Rotating shaft on described blade 21 is positioned at blade 21 leading edge side.
Use state that this practicality new is described below.
Described three set blade assemblies 2 are arranged on wheel hub 1, under wind-force effect, hub spindle 22 is around blade 21 coaxial rotating, the some spring-dampers 23 installed on blade 21 and hub spindle 22 contact with each other and provide bounce, when the blade torque balance that this bounce produces with wind-force, blade 21 and hub spindle 22 no longer rotate against；When wind speed changes, the blade torque that bounce and wind-force produce regulates mutually until reaching equilibrium point, thus regulating blade 21 and hub spindle 22 to reach automatically to become the purpose of oar.
