Huastron prestressed frame steel tube wind tower invested by Qingdao Jinjiaozhou Asset Management Co., Ltd. measures 170 meters high.
The shape now designed by “Huastron” is a type of frame. The four corners have stronger bearing capacity through the lower tower body, which solves the problem of welding fatigue and can effectively avoid resonance. , this technology with more than 20 national and international patents can significantly increase the height of the tower, better utilize wind resources and increase the effective hours of electricity generation.
The production process of wind towersGenerally as follows:
Cutting by CNC cutting machine, thick plates need be beveled, after the plate is formed by the plate rolling machine, spot welding, positioning and welding the seams alongInterior and exterior inspections are carried out after confirmation. After the roundness inspection, if there are any problems, a second rounding is performed. The single-section cylinder is welded, a hydraulic unit is used to align the rollers. Once the frame is assembled and tack welded, the interior and exterior circumferential seams are welded.
After straightness inspections and other tolerance inspections, after flange welding, welding non-destructive testing and flatness inspection, sandblasting and painting, after installation of parts After internal inspection and finished product inspection, they are transported to the installation site. .
What are the basic components of offshore wind farms and their construction methods?
Data from a wind tower cannot estimate electricity production in the region. If you have data for one year but you don'tdon't know how to estimate them, just average the data for the whole year to see. if it can reach 5 m/s. Above, if it can reach more than 5 m/s, find a qualified company to assess the area.
The manufacturer of the anemometer tower provides this answer.
Offshore wind farms mainly refer to offshore wind power with a water depth of around 10 meters. Compared with onshore wind farms, the main advantages of offshore wind farms are that they do not occupy land resources, are basically not affected by topography, have higher wind speeds, larger wind turbine capacity individual (3 to 5 MW) and higher annual hours of use. However, the construction of offshore wind farms is also technically difficult, and the construction cost is generally 2-3 times that of onshore wind farms.. China is rich in offshore wind energy resources, and they are mainly distributed in southeastern coastal areas with developed economies, strong power grid structures, and a lack of conventional energy sources. The first domestic offshore wind farm, the Shanghai Donghai Bridge 100,000-kilowatt wind farm project, has started construction and is expected to be completed and put into operation in 2009. China's developable offshore wind resources are approximately 750 million kilowatts, three times those of onshore wind resources. For example, the annual effective wind hours of Donghai Bridge Wind Farm exceed 8,000 hours, and the full load hours after it is put into operation can reach more than 2,600 hours. The efficiency of electricity generation is more than 30% higher than that of onshore wind power. farms.
