Abstract

The utility model relates to a wind-driven generator set. A plurality of generators with small capacities are arranged on a main shaft of a wind power machine in series. According to the capacity requirements, two or more than two generator rotors with small capacities are arranged on the main shaft, stators are sheathed outside the rotors and are fixed a pedestal, or the shafts of a plurality of small generators are connected by a shaft coupling. The utility model solves problems that the generator is difficult to manufacture, process, install and transport after the capacity of the generator is increased to cause the diameter of the generator to be increased, and the efficiency of the generator is low when the generator runs at a low wind speed.

Description

String shaft type wind energy conversion system
Affiliated technical field
The utility model relates to a kind of wind power generating set.
Background technique
General wind power generating set is to adopt wind wheel directly to link to each other with a generator, and generator is after capacity increases, and diameter is big, and manufacturing, installation and transportation be unusual difficulty all, and low wind speed when moving efficient lower.
Summary of the invention
The utility model solves generator after capacity increases for a kind of string shaft type wind energy conversion system, and diameter is big, and manufacturing, installation and transportation be unusual difficulty all, and the lower problem of efficient during the operation of low wind speed.
The technical scheme in the invention for solving the above technical problem comprises: the generator string of a plurality of small capacities is on the wind energy conversion system main shaft.On a main shaft,, do two or more small-capacity generator rotors, stator is enclosed within the rotor outside, and fix, perhaps couple together by the axle of coupling with a plurality of small generators with pedestal according to the needs of capacity.
The beneficial effects of the utility model are: the wind energy conversion system that a kind of new structure is provided, well utilized wind energy conversion system engine room inside space, make the wind energy conversion system more reasonable structure, set engine room base, main shaft and yaw system are stressed better, after having solved the wind energy conversion system capacity and increasing, manufacturing, installation, transportation and problem difficult in maintenance, the generating efficiency when having improved low wind speed operation, and guaranteeing to realize the increase of unit capacity easily under the constant situation of unit overall structure.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Main shaft 3 is connected with engine room foundation 1 by bearing 7, and two or more small-capacity generator rotors 5 are on main shaft 3, and stator 2 is enclosed within rotor 5 outsides and fixing with pedestal 1, perhaps couple together by the axle of coupling 6 with a plurality of small generators, and the 4th, wheel hub.
