Problems solved by technology
During the rotation of the nacelle 1, the upper end of the cable 3 does not bear the torsional moment, but the lower end bears a large torsional moment. The lower end of the cable 3 will break due to excessive force, which seriously affects the service life of the cable 3

The invention discloses a wind driven generator comprising a cabin and a tower. The ends of cables connected to the cabin are fixed to the saddle bridge of the tower. At least one fixing disk is arranged on the vertical portions of the cables. The fixing disk comprises an inner ring and an outer ring. Cable holes are formed in either the inner ring or the outer ring, and the fixing disk is installed by the inner ring or outer ring in the tower at a preset height through a fixing device and the cable holes can rotate relative to the fixing device. The cabin of the wind driven generator rotates along with the wind direction, and the cables rotate along with the rotation of the cabin. When the cables rotate along with the rotation of the cabin, the fixing devices for installing the fixing disks rotate relative to the cable holes of the fixing disks and the cables rotate unlimitedly, so that reversion is generated on the vertical portions of the cables, reversion degree on the shorter cables on the saddle bridge is decreased, torque on the shorter cables is reduced and service lives of the cables are prolonged.
Description
technical field [0001] The invention relates to the technical field of wind power generation, in particular to a wind power generator. Background technique [0002] As a clean and renewable energy, wind energy has been paid more and more attention by countries all over the world. Wind power is an inexhaustible clean and non-polluting energy source, and it is currently the world's largest new energy source of economic development. [0003] Wind power generation is to convert the kinetic energy of the wind into mechanical energy, and then convert the mechanical energy into electrical energy. The principle is to use the wind to drive the wind rotor blades to rotate, and then increase the speed of rotation through the speed increaser to promote the generator to generate electricity. [0004] The wind rotor of the wind generator includes at least two blades, and when the wind blows to the blades, the aerodynamic force drives the rotation of the wind rotor. Since the speed and ...
