Description

Megawatt wind-power blade subsection laying device

Technical Field

The utility model relates to a megawatt level wind-powered electricity generation blade makes technical field, especially relates to a megawatt level wind power generation blade segmentation laying device.

Background

In recent years, wind power generation, which is one of the most important new energy sources, has important significance in alleviating energy shortage, improving the environment and the like. With the development of social economy, fossil fuels are gradually exhausted, people face the crisis of energy and environmental pollution, and wind energy is taken as a clean renewable energy source, plays an increasingly important role in the development of social economy and has huge development potential. By the end of 2015, the national power generation and installation amount has broken through 150673 ten thousand kilowatts, wherein the installed capacity of thermal power reaches 99021 ten thousand kilowatts and accounts for 65.7 percent of the total installed capacity. The thermal power generation is at the cost of coal consumption, and the environmental pollution is more and more serious. Therefore, the new energy strategy in China begins to set the vigorous development of wind power generation as the key point for developing and utilizing wind energy resources, so that the wind power generation system can become a new alternative energy and is beneficial to environmental protection. In wind energy development, the wind turbine blade is used as an engine of a wind power generation device, and the quality and reliability of a generator set are determined to a great extent, so that material selection, design and manufacturing are very critical. As blades have been enlarged, large blades using a composite material as a main material have been widely used. The glass fiber reinforced plastic blade has been widely used as a blade material because of its advantages of high fatigue strength, low notch sensitivity, good corrosion resistance, easy molding, and capability of designing strength and rigidity according to the stress characteristics of the blade. At present, the commercialized large wind turbine blades are mostly made of glass fiber reinforced plastic composite materials. However, as the stand-alone power of wind turbines continues to increase, the length of the blades also continues to increase. The difficulty of blade manufacturing is also gradually increased, and the integral blade laying is not only labor-consuming and time-consuming, but also can increase the use frequency of traveling crane, and cause the waste of personnel and machines.

Disclosure of Invention
