Description
Technical field
The present invention relates to wind-power generating unit tower system and the construction method thereof of the ladder walking support of a kind of side.
Background technique
Wind energy is as green clean energy resource, and with unprecedented speed in fast development, at the end of 2014, China's installed capacity of wind-driven power leaps to the first in the world.The single-machine capacity of wind-driven generator is also increasing, and shaft tower is also more and more higher.The maximum wind-driven generator of current state inner capacities is the 8MW that Dynamics Co., Ltd is closed in state Electricity Federation.Fan blade length more than 100 rice of current 4.5MW, axial fan hub height has reached 120 meters.According to the statistical law prediction of blower fan development, be expected to reach 20MW to separate unit fan capacity during the year two thousand twenty.
Along with the increase of fan capacity, tower height is also more and more higher.From the angle of structural mechanics, as the head tower that unique vertical supports, not only subject the huge gravity of whole blower fan, also subject the lateral pull of blower fan.The gravity of whole blower fan and lateral pull finally all concentrate on head tower base and basis, this just brings huge challenge to basis and head tower structure and intensity, basis will be increasing, head tower is also more and more thicker, be unfavorable for making full use of wind energy, also be unfavorable for reducing Wind turbines cost, improve wind-powered electricity generation competitive ability.If change blower fan pylon into Vertical Triangular that vertical support and skewed horizontal load form by current single head tower to construct, will greatly increase the anti-transverse force of pylon, and so greatly can reduce the requirement on vertical tower and basis, thus greatly reduce engineering cost.Moreover, as long as pylon steadiness solves, also can increase the utilization ratio of windward side wind energy, current single-wheel hub Three-blade is increased to double wheel hub six blade etc., and do not increasing on the basis of tower height, wind energy utilization significantly improves.
In addition, from the functional requirement to Wind turbines itself, driftage control be ensure blower fan front windward, play the major measure of blower fan optimal output, be absolutely necessary self-contr ol function.The driftage of current blower fan controls to realize by the rotation of driven by servomotor nacelle atop.The nacelle weight of current 4.5MW capacity reaches 400 tons, and the motor driving cabin to rotate needs very large driving force.If driftage is controlled draw-bar lengthen, from mechanics principle, then the vertical projection length of the driving force needed and draw-bar is inversely proportional to, and driftage driving force can reduce greatly, and driftage drives also dexterousr.
