| Title 1:A Title 2:C |
| This question examines atmospheric movement. Quick question 1: The image shows that at the same height, the wind speed at sea is higher than that on land, that is, the power generation capacity of wind towers at the same height at sea is higher than on land, so element A is correct. Quick question 2: We can see from the figure that the slope of the ocean curve below 40 meters is greater than the slope of the land curve. Therefore, the wind speed in the ocean below 40 meters increases. rapidly with increasing height. When above 40 meters, the wind speed on land increases rapidly with increasing height, so item C is correct. |
How to use data from a wind tower to estimate electricity productionin the region
Qingdao Jinjiaozhou The Huastron pre-stressed frame steel tube wind tower invested by 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, once the plate is formed by the plate rolling machine, spot welding, positioning and weldingge of the interior and exterior longitudinal seams 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 checks and other tolerance inspections, after flange welding, non-destructive testing and flatness inspection of welds, sandblasting and painting, after completion of the installation of internal parts and inspection of the finished product, transportation to the installation site.
What is a wind tower accessory?
Data from a wind tower cannot estimate electricity production in the region if you have a year of data but don't have any. I don't know how to estimate it,first average the data for the whole year to see if it can reach more than 5 m/s, then find a qualified company to assess the area.
The wind tower manufacturer provides this answer.
Support device for wind turbines. According to the official website of Jiuzheng Building Materials Network, wind turbine accessories are supporting devices for wind turbines. Wind towers are made of large diameter steel pipes and are equipped with accessories such as ladders, platforms, cable supports, electrical panel positioning, etc. Accessories are required to support power generation devices.
