Description
Technical field
The present invention relates to a kind of wind power plant, especially a kind of wind collecting device and wind-power generating system thereof.
Background technique
Wind-power electricity generation is that the world obtains one of most important mode of the energy.Along with the resource exhaustion of the earth, it is also increasingly high that people obtain the cost of the energy.But wind is to shine upon the earth to make the spontaneous product of air flow, and wind energy is a kind of product of solar energy strictly speaking.Wind energy safety, cleaning, aboundresources, inexhaustible.The most important thing is that wind energy is a kind of local resource of nonvolatil a large amount of existence, can energy supply steady in a long-term be provided for us, it does not have the raw material risk, does not more have the fuel price risk, can not produce the carbon discharge capacity yet.Although the advantage of wind-power electricity generation is a lot, because the limitation of power generating equipment makes wind-power electricity generation can not be had, use widely, especially because the generating efficiency that the many disadvantages of power generation system causes is not high, and the equipment cost investment is big.At present, traditional wind power plant is as long as the problem that exists is following:
1, traditional single turbine wind-driven generator is in order to absorb bigger wind energy; Generally all be to rely on the increasing wind sweeping area to realize, will cause the deployment cost (like ground, body of the tower, yaw system, platform, cabin, transportation, installation etc.) of some basic components and supporting facility to increase like this.
2, the traditional constant wind-driven generator of rotor speed, it can only guarantee the wind energy conversion efficiency under certain wind speed, tip speed ratio is optimum, reaches the highest wind energy capturing efficiency.In addition; The described same employing oil hydraulic pump of existing some patent is come converting wind energy, and in the wind-power generating system through hydraudynamic drive, control output flow through adopting variable displacement pump; Perhaps in the pipeline that fluid power is carried, various hydraulic function elements are set and control the pressure of transmitting fluid and the requirement that flow velocity satisfies best tip speed ratio; Though satisfied the requirement of tip speed ratio so reluctantly, also make energy in the process of transmitting, increase along the stroke pressure loss; Energy consumption increases, and generated energy is less.
3, the wind speed size of nature changes at any time, and traditional wind-driven generator is in the transmission and conversion chains link of its whole energy; Each functional unit all need dispose by the parameter of peak demand could satisfy its safety in utilization requirement; But, can only exert oneself by little load in the time at most low wind speed, have the installation wasting of resources greatly; An i.e. year generating utilizes hour number (converting the full load electric motor power) low especially, can only reach about 40% of general hydropower generator group.
4, traditional wind-driven generator, its Transmitted chains is short, and the rigidity foot, when wind speed suddenly change, can cause unexpected impact injury to mechanical parts, and part is the fatigue damage of appearance ahead of time, reduces the whole service life of system greatly.

The top of above-mentioned body of the tower is provided with one can be around the mountion plate of body of the tower gyration center driftage rotation, and said mountion plate is controlled driftage rotation platform, and said two water pumps are fixed on the upper side of mountion plate.
High pressure on the cylinder body on the above-mentioned slow-speed of revolution plunger pump goes out water one-way valve, connects high-pressure outlet, and all high-pressure outlets conflux through certain level; Finally conflux in the house steward of confluxing; Said unsteady connecting sleeve comprises can make overcoat and the interior cover that relative 360 degree rotate, and is provided with seal ring between the inside and outside cover, and inside and outside cover cooperation has formed the hollow pipeline that floats; The described house steward of confluxing is fixedly connected with the interior cover of rotatable unsteady connecting sleeve; The overcoat of said unsteady connecting sleeve is fixed on the upper end portion of high-pressure water pipeline, and said high-pressure water pipeline is arranged in the body of the tower, through to ground.
Another technological scheme of the present invention is: a kind of wind-power generating system; Comprise the wind collecting device of the some that is evenly distributed in the wind energy turbine set, it is characterized in that: be transported to the high-pressure water flow on ground from the high-pressure water pipeline of each wind collecting device, after confluxing, feed high pressure water delivery house steward; Said high pressure water delivery house steward end is provided with nozzle; High-pressure water flow ejects from nozzle, drives the water turbine rotation, and water turbine drives generator again and produces electric energy.
Said nozzle is quantitative nozzle.
