Background technique
Along with society is to the concern of environmental problem and energy crisis, wind energy has very high value as a kind of clean energy resource.In order to improve generated output and the generating efficiency of wind power plant, wind-driven generator single-machine capacity is towards powerful future development.Existing wind-driven generator is generally impeller-driven booster engine then drive electrical generators, is exactly impeller Direct driver wind-driven generator in addition, so-called exactly straight drive blower (blower fan not with booster engine is straight drive blower).Current wind-driven generator single-machine capacity has reached several megawatt, and impeller diameter reaches rice up to a hundred.But, due to time variation and the seasonality of wind speed, result through electric energy power that wind-driven generator sends and frequency is difficult to keep stable, wind-driven generator is wanted to access electrical network, need to convert the electric energy sent to electrical network required voltage and frequency with current transformer and transformer, because the technical difficulty of large megawatt current transformer is large, cost is very high, and wind-power electricity generation also also exist society peak times of power consumption there is no wind, and it is larger at low peak period wind, because power storage difficulty is very large, seriously constrain the development of wind-driven generator.
Summary of the invention
For solving the problems referred to above that prior art exists, the utility model will design a kind of impeller Direct driver wind-driven generator that Wind resource change can be become the electric energy of frequency stabilization.
To achieve these goals, the technical solution of the utility model is as follows: a kind of impeller Direct driver wind-driven generator, comprise draught fan impeller, oil hydraulic cylinder, spring, cam turntable, bearing, support, high-pressure oil passage, low pressure oil way, main frame, tower cylinder, fuel tank, accumulator, high-speed hydraulic motor and generator, described impeller is connected with cam turntable, cam turntable is rack-mount by bearing, support is connected with the main frame being arranged on tower cylinder top, hydraulic cylinder body is connected with support, spring fitting is between the cylinder body and piston of oil hydraulic cylinder, hydraulic cylinder piston contacts with cam turntable, the oil outlet of high-pressure oil passage connecting fluid cylinder pressure and accumulator, the filler opening of low pressure oil way connecting fluid cylinder pressure and fuel tank, accumulator is connected with high-speed hydraulic motor filler opening, fuel tank is connected with high-speed hydraulic motor oil outlet, high-speed hydraulic motor is connected with generator.
Compared with prior art, the utility model has following beneficial effect:
1, hydraulic type directly drives cam blower fan and refers to the wind powered generator system mechanical drive train between wind wheel and generator being replaced to flexible hydraulic transmission system.Hydraulic transmission technology has the advantages such as stable drive, volume is little, quality is light, bearing capacity is large, structure is simple, the life-span is long, the difficult point that the utility model utilizes hydraulic transmission technology to solve to exist in prior art:
First, the Wind resource change of instability become the stabilized (steady-state) speed required by industrial frequency generator by hydraulic volume speed governing, effective realization controls generator constant frequency;
Secondly, hydraulic transmission is flexible dynamic transmission, makes the flexible layout of power generation system easy for installation, what be conducive to its resource distributes the expansion regulated with product function rationally, also can carry out many-side to control, such as increase accumulator energy storage, realize the stable of system pressure and continue generating.
2, in the utility model, draught fan impeller drives cam turntable to rotate, cam turntable drives the piston up-down of oil hydraulic cylinder, namely by cam turntable, the rotary motion of impeller is become the straight line motion of hydraulic cylinder piston, thus realizes the process of Wind resource change hydraulic energy.
3, in the utility model, wind energy unnecessary for electricity consumption low peak period can store with the form of hydraulic energy by accumulator, change the hydraulic energy of storage dress into electric energy in peak times of power consumption, and then solve peak times of power consumption and there is no wind, and in the larger difficult problem of low peak period wind.
4, in the utility model, when wind speed is lower than blower fan rated wind speed, utilize the pressure oil in hydraulic system to drive pitch-controlled system, adjustment blade pitch angle catches maximal wind-energy; When wind speed is higher than blower fan rated wind speed, improves impeller moment of torsion by adjustment Hydraulic Power Transmission System pressure, and then control wheel speed.The hydraulic system achieved by controlling to be easy to control controls the object of blower fan.
5, in the utility model, accumulator can the pressure of stable hydraulic transmission system and flow, although wind has time variation, this Hydraulic Power Transmission System also can provide continual and steady hydraulic energy for high-speed hydraulic motor, thus generator can be driven to provide stable electric energy.
