Problems solved by technology

[0007] The existing direct-drive wind turbines fix the impeller locking mechanism inside the bearing housing, and the operating space of the stator is small; when braking, the method of gear meshing is used to achieve the purpose of locking, the friction between the gears is large, and the wear rate is high. It will increase the load of power generation and affect the efficiency of power generation

Abstract

The invention discloses a double-stator direct-drive wind generating set in an impeller locking mode, and relates to the technical field of wind power generation. A cabin shell is arranged on a tower frame, and an electric appliance cabinet is arranged in the cabin shell; a wind measuring instrument on the outer side of the cabin shell is connected with the electric appliance cabinet, and a yaw motor is arranged on one side of the electric appliance cabinet and is connected with the right side of a disc type rotor; a locking device is connected with the left side of the disc type rotor; a plurality of middle stators are evenly arranged in the middle of the disc type rotor, and an outer stator is mounted on the outer walls of the middle stators; a hub is connected with the locking device; and one end of each impeller is connected with the hub. An impeller locking mechanism is large in movable space, and a double-stator control structure can relieve impact force of external force to parts; the disc type rotor is good in flexibility, good in locking effect, resistant to wear and long in service life; and the operation safety coefficient is high, and maintenance cost is low.

Description

Technical field: [0001] The invention relates to the technical field of wind power generation, in particular to a double-stator direct-drive wind power generating set in the form of locked impellers. Background technique: [0002] As a clean and renewable energy, wind energy has been paid more and more attention by countries all over the world. Its reserves are huge. The global wind energy is about 2.74×10^9MW, of which the usable wind energy is 2×10^7MW, which is 10 times larger than the total amount of water energy that can be developed and utilized on the earth. The wind has been used by people for a long time-mainly through windmills to pump water, grind flour, etc., but now, people are interested in how to use wind to generate electricity. [0003] Convert the kinetic energy of the wind into mechanical kinetic energy, and then convert the mechanical energy into electrical kinetic energy, which is wind power generation. The principle of wind power generation is to use ...
