Wind driven generator with wind resistance reducing blades

Abstract

The invention relates to the technical field of wind power generation, in particular to a wind driven generator with wind resistance reducing blades. The wind driven generator comprises the blades, a rotating shaft, an adjusting mechanism, a power generation box body, a resistance mechanism and a transmission mechanism. The blades are arranged at the front end of the rotating shaft, the adjusting mechanism and the resistance mechanism are arranged in the middle of the outer wall of the rotating shaft, and the transmission mechanism is arranged in the rotating shaft. The tail end of the rotating shaft is arranged in the power generation box body, the rotating shaft is rotationally connected with the power generation box body, the ends, close to the rotating shaft, of the blades are fixedly connected with fixing columns, the fixing columns penetrate through the outer wall of the rotating shaft, and the outer walls of the fixing columns are fixedly connected with connecting bearings. According to the wind driven generator with the wind resistance reducing blades, the blades can be adjusted according to the wind speed, the normal work of the blades is ensured, meanwhile, the deformation and damage phenomena of the blades due to too large wind force are reduced, when the rotating shaft is too fast, the speed can be actively reduced, and the situation that the rotating shaft works in an overheat environment for a long time and is damaged is avoided.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a wind power generator with blades for reducing wind resistance. Background technique [0002] A wind generator is a power device that converts wind energy into mechanical work, which drives the rotor to rotate, and finally outputs alternating current. The principle of wind power generation is to use the wind to drive the blades to rotate, and then transmit the power to the generator through the components in the power generation box. , to prompt the generator to generate electricity. [0003] When the wind speed gradually increases, the wind resistance of the blade will also increase accordingly. When the blade is subjected to excessive wind resistance, deformation and damage will occur, which is not conducive to the normal operation of the blade. At the same time, the speed of the blade will increase rapidly when the blade is subjected to excessive wind resistance...

Problems solved by technology

[0003] When the wind speed gradually increases, the wind resistance of the blades will also increase accordingly. When the blades are subjected to excessive wind resistance, deformation and damage will occur, which is not conducive to the normal operation of the blades. Drive the rotating shaft to rotate synchronously and quickly, resulting in a rapid increase in the temperature of the rotating shaft, and at the same time will cause the temperature of the generator inside the power generation box to rise, and work in a high temperature environment for a long time, which will affect the life of the generator
