Embodiment 1

[0018] Embodiment 1: A vertical-axis wind-driven generator, including a wind blade 1, a disc motor 2, a blade bracket 3 and a column 4, the vertical-axis wind-driven generator also includes a wind-shielding wind collecting plate 5, a wind speed sensor 6, Controller 7, angle adjusting device 8 and empennage 9; wind speed sensor 6 is used for sensing wind speed, and wind speed signal is transmitted to controller 7, and controller 7 analyzes wind speed signal, and when wind speed is greater than the rated wind speed of wind-driven generator, controller 7 controls The angle adjusting device 8 changes the angle of the empennage 9 to block the wind collecting plate 5, thereby limiting the rotating speed of the fan blade 1. When the wind speed is lower than the rated wind speed of the wind generator, the controller 7 controls the angle adjusting device 8 to change the angle of the empennage 9 so that The wind collecting plate 5 collects the wind, so as to collect wind energy and incre...

Embodiment 2

[0023] Embodiment 2: On the basis of Embodiment 1, the wind blade 1 is also provided with a starting wind cup 11. Since the rotation of the wind blade 1 requires a large force to start, when the wind speed is small in this design, the rotating wind cup can The rotation force is provided to drive the fan blades to rotate, which can avoid using a starter motor to drive the fan blades to rotate.

Embodiment 3

[0024] Embodiment 3: On the basis of Embodiment 1, the disc motor 2 is also provided with an irreversible disc 21, and the irreversible disc 21 is provided with a starting wind cup 22, so that it is designed to be rotated when starting. The wind cup 22 drives the wind blade 1 to reduce the starting wind speed. When the wind speed increases, the resistance of the starting wind cup 22 increases faster, and the higher speed of the wind blade 1 will not be affected by the wind cup.

Abstract

The invention provides a vertical-axis wind driven generator. The vertical-axis wind driven generator comprises fan blades, a disc-type motor, fan blade supports and a vertical column. The vertical-axis wind driven generator is characterized by further comprising a wind blocking and collecting plate, a wind velocity transducer, a controller, an angle adjusting device and an empennage; the wind blocking and collecting plate is a cone and comprises a large wind collecting port and a small wind exhaust port, the fan blades and the disc-type motor are arranged on the wind exhaust port in the cone of the wind blocking and collecting plate, and the wind blocking and collecting plate is connected with the vertical column through a bearing; the wind blocking and collecting plate is arranged on the vertical-axis wind driven generator, wind can be collected when the wind velocity is smaller than the rated wind velocity, the wind power utilization rate is increased, when the wind velocity is larger than the rated wind velocity, wind is blocked, the rotating speed of the generator is limited, the generator and a circuit are protected, a velocity-limiting mechanism is separated from and is not directly connected with a wind driven generation mechanism based on the wind blocking velocity-limiting principle, the wind driven generation mechanism is more stable, and high-strength materials do not need to be utilized to overcome the influences caused by instability.

Description

technical field [0001] The invention relates to the field of wind power generators, in particular to a vertical axis wind power generator. Background technique [0002] Wind energy is an inexhaustible renewable emerging green energy. Therefore, countries and governments around the world have raised the wind power industry to an important position and vigorously promoted and supported it. my country is one of the first countries to develop vertical-axis wind turbines. Compared with horizontal wind turbines, vertical-axis wind turbines have the advantages of low noise, high utilization rate of wind energy and low start-up wind speed. In the prior art, vertical axis wind turbines are mainly divided into two types: drag type and lift type. The drag type vertical axis wind turbine mainly uses the resistance difference generated by the air flowing through the blades as the driving force, while the lift type uses the lift generated by the air flowing through the blades as the dri...
