Problems solved by technology

[0005] The purpose of the present invention is to provide a full-blade-tip impeller double-drive high-efficiency wind power generator, which solves the problem that one impeller of the existing full-blade-tip impeller wind power generator only uses one method to directly drive or semi-directly drive one generator. The connection of the drive shaft is too long, the adaptability to the change of wind force is poor, and it is difficult to adjust the load of the generator, which leads to low work efficiency

Abstract

The invention aims to provide a full-blade-tip impeller type double-drive efficient wind-driven generator. The problem that an impeller of an existing full-blade-tip impeller type wind-driven generator only drives one generator, a transmission shaft is too long, the adaptability is poor, the load is difficult to adjust, so that the working efficiency is caused to be low are solved, according to the technical scheme, the inner side of a wheel edge of the full-blade-tip impeller is connected with a double-disc-shaped flange through a stay cable, a main shaft is provided with a front generator and is arranged on a yaw platform through two front bearings, an inner gear ring at the rear end of the main shaft sequentially passes through an outer gear shaft, a clutch and a driven shaft is in transmission connection with the driven shaft, and the rear end of the driven shaft is connected with a rear generator rotor. The impeller of the generator is reasonable in design, two generators capableof directly driving and semi-direct driving can be utilized, so that the starting wind speed of a single machine is reduced, and the efficiency of the wind-driven generator is improved.

Description

technical field [0001] The present invention relates to a wind power generating device, especially a full-blade impeller type high-efficiency wind power generator with all blades arranged on the outer rim and a group of impellers directly driving or semi-directly driving two or more generators. It is suitable for various wind power generation sites. Background technique [0002] At present, most of the widely used large-scale horizontal-axis wind power generation devices powered by wind energy adopt a structure in which three blades are arranged on a traditional hub. This kind of wind power device has few blades, the torque is small for the impeller as a whole, and the aerodynamic performance is poor. This kind of traditional blade is bulky, and the wind blocking area in the middle of the wind wheel is large, which requires high material requirements and low efficiency. Transportation, hoisting, and manufacturing High cost; moreover, a group of wind wheels can only directly...
