Embodiment Construction
[0037] The present invention is further described below by way of an embodiment, but does not therefore limit the present invention to the scope of the embodiments.
[0038] The present embodiment provides a wind power generation system, the wind power generation system comprises a modular wind power concrete tower. as Figures 1 through 4 As shown, the modular wind power concrete tower comprises several inclined barrel joints 3 and at least one straight barrel joint 2, straight tube joint 2 and several inclined tube joints 3 stacked in a vertical direction and form the tower body 100; at least one straight tube joint 2 inserted into several inclined tube joints 3, so that the tower body 100 meets the clearance distance requirements and / or tower frequency requirements of its outer surface and the blade tip.
[0039] In the tower body 100, according to the slope of several inclined tube joints 3, the height of the tower body 100, and the clearance requirements of the tower body 10...

The invention discloses a modular wind power concrete tower, a wind power generation system and a manufacturing method, the modular wind power concrete tower comprises a plurality of inclined barrel sections with the same slope and at least one straight barrel section, and the straight barrel section and the inclined barrel sections are stacked in the vertical direction to form a tower body; and the at least one straight barrel section is inserted into the inclined barrel sections, so that the tower body meets the clearance distance requirement of the outer surface of the tower body and the blade tip and / or the tower frequency requirement. The wind power generation system comprises the modularized wind power concrete tower. The straight barrel section is inserted into the butt joint face of the inclined barrel section in the height direction according to the tower frequency and blade tip clearance requirements, so that the height of the tower body can be adjusted, the tower frequency and blade tip clearance can be adjusted in the favorable direction, the risk that a mixed tower mold is rapidly eliminated by the large-scale trend of a fan can be avoided through modular design, and the production efficiency is improved. And healthy and efficient development of the standardized mixing tower is further facilitated.
Description
Technical field [0001] The present invention relates to a modular wind power concrete tower, a wind power generation system and a production method. Background [0002] As the height of the tower increases and the diameter of the main engine impeller increases, large wind turbines will put forward more stringent requirements for concrete towers in terms of tower frequency control and tip headroom. At present, the mainstream gradient concrete tower form is from the bottom of the tower to the top of the tower to present a linear change in the external diameter, when the height of the tower needs to be raised, often at the bottom of the original tower to continue the original tower exterior slope continues to connect the tube ring, so that the diameter of the bottom of the tower linear increase, which makes the first order frequency of the tower too high, and prone to the design problem of leaf tip clearance interference.
