Description
Technical field
The present invention relates to a kind of detachable wind generator set blade and mounting and dismounting method thereof.
Background technique
China's southeastern coast Economic contrast is flourishing, and power consumption is large, and does not almost have coal resources, and the problem that dependence fossil energy solves energy demand is very difficult.Southeastern coast and island wind resource thereof enrich, and possess the primary condition of development wind-power electricity generation and strong exploitation desire.But the attack that all can be subject to typhoon summer that this area is annual, coastal area all once strong wind process after each Landed Typhoon, along with global warming, intensity of typhoon also has the trend strengthened year by year.High wind adds that the rotation from center of typhoon is violent strengthens, and the turbulence intensity increased exponentially and rapids can produce great collapsing force to wind power generating set, and wind wheel blade is impaired particularly serious.
Traditional fan blade of wind generating set is all integrated, although also have subsection blade, its starting point is mainly for the ease of transport and installation.
The patent No. is that the Chinese earlier application " a kind of Large-scale Wind Turbines blade and application thereof " of CN201210225362.1 discloses a kind of foldable type blade on length of blade direction, blade is made up of end section, top section and fold mechanism, and folding position is arranged on apart from blade tip 15% to 50% length of blade place.Section at the bottom of blade and blade top section are connected by foldable shaft, and blade top section can rotate around foldable shaft.After leaf folding, the acting force arm of vane stress can be reduced; And make the direction of the lift suffered by the section of blade top and resistance reverse, thus make blade top section and the stressed of end section have part to cancel out each other, reduce the load of root of blade and unit, thus improve the ability of resisting high wind of blade under typhoon operating mode.Drive unit in fold mechanism is that motor drives or hydraulic driving.Blade uses locking device when completely folding or full open position, and locking device is hydraulic locking or electromagnetic locking, and has for identifying the folding position state sensor that blade current state and jackknife action control.
The greatest problem that this earlier application exists is that driving in fold mechanism and actuating device must be arranged on blade interior, make in leaf folding process at driving fold mechanism, driving force needed for it is very large, in order to ensure that fold mechanism can steadily reliably work, the volume of fold mechanism is inevitable very huge, the weight of fold mechanism also strengthens thereupon, and this not only fundamentally changes blade initial quality and center of gravity, also produces impact greatly to the aerodynamic quality of blade.Even if design blade for it specially, the reliability of fold mechanism and locking device is also difficult to ensure, as long as wherein the fold mechanism of any one blade and locking device break down, the serious accident of fatal crass just likely occurs.In addition, when after leaf folding, the heavy rain arrived with typhoon can be poured in the inner chamber of at least one blade, after a large amount of rainwater injects, the serious consequence such as must cause very serious infringement to the electric control system of wind wheel inside, even cause unit breaking out of fire, topple.
