Abstract

The invention discloses a construction method of a single vane installation technique of a large wind driven generator, and relates to the technical field of new energy technology. Firstly, a main crane and an auxiliary crane cooperate to install a first section of tower drum, a second section of tower drum and a third section of tower drum; then, an engine room and a fan hub are installed; finally, a first single vane is horizontally installed; then an impeller is rotated by 120 degrees to lock braking; a second vane and a third vane are installed in the same way; electricity is checked, anddebugging is performed to guarantee that faults are absent; test run is done; and installation is ended. By applying the construction method disclosed by the invention, the installation problem of thelarge wind driven generator under special environmental conditions, such as mountain regions, intertidal zones and coastal regions, can be effectively solved; construction is convenient; the construction speed is fat; investment is reduced; the cost is reduced; and the installation efficiency of the wind driven generator is increased.

Description

technical field [0001] The invention relates to the field of new energy technology, in particular to a single-blade installation method for large-scale wind power generators, which is suitable for the installation of large-scale wind power generators in various complex environmental conditions such as coastal beaches, mountainous areas, and seas. Background technique [0002] With the increasing scarcity of world energy and the rapid development of science and technology, coupled with people's requirements for environmental protection, people are trying to find a renewable, environmentally friendly and clean green energy that can replace oil, natural gas and other energy. Wind energy is currently the most promising new type of energy. It is an inexhaustible energy source and a clean, pollution-free, renewable green energy source. my country is the country with the highest share of wind power resources in the world, and it is also one of the first countries in the world to ut...
