Description
Technical Field
The utility model relates to a wind turbine blade mould field specifically is a detachable upset roof beam that is used for upset wind turbine electricity generation blade mould.
Background
Wind energy is increasingly gaining attention as a clean renewable energy source in all countries of the world. The energy storage capacity is huge, the global wind energy is about 2.74 multiplied by 109MW, and the available wind energy is 2 multiplied by 107MW which is 10 times larger than the total amount of water energy which can be developed and utilized on the earth. Wind is utilized by people for a long time, mainly water pumping, surface grinding and the like are realized through windmills, people are interested in how to utilize wind to generate electricity at present, and the principle of wind power generation is that wind power is utilized to drive blades of the windmills to rotate, and then the rotating speed is increased through a speed increaser to promote a generator to generate electricity. According to the current wind power generation technology, the power generation can be started at a breeze speed of about three meters per second. Wind power generation is forming a hot tide in the world because it has no fuel problems and does not produce radiation or air pollution.
With the rapid development of the state on clean energy, the wind power industry is rapidly developed, the megawatt level of the wind power blade is larger and larger, the length of the wind power blade is from forty meters to eighty meters, the wind power blade is lengthened day by day, the length of the die is lengthened, the web plate of the wind power blade is also larger and longer, and meanwhile, the size of the wind power blade is larger and larger as the main stream wind power demand is more and more.
The turnover beam is a very critical structure in the mainstream wind power blade mould, the number of the turnover beams in the current mainstream wind power blade mould is about twelve, six upper beams are arranged in the upper mould, and six lower beams are arranged in the lower mould.
