Problems solved by technology

But in this way, the rated wind speed of the vertical axis wind turbine will inevitably be designed very high, but considering the characteristics of the generator itself, for a generator with a high rated wind speed, its efficiency is very low at low wind speeds, and at low wind speeds. Under normal natural conditions, most of the time it is in a low wind speed environment, so the above design scheme will reduce the efficiency of the vertical axis wind turbine

Embodiment 1

[0020] Such as figure 1 , 2, and 3 are schematic structural diagrams of Embodiment 1 of a constant power output device for a vertical-axis wind-driven generator according to the present invention, respectively. The structure of this device is made up of blade 1, blade support 2, rocking arm 3, rotating shaft 4, cantilever support 5, spring 6. The rocking arm 3 is connected with the cantilever bracket 5 through the rotating shaft 4, and the rocking arm 3 can rotate along the horizontal direction with the rotating shaft 4 as an axis; one end 31 of the rocking arm is connected to the blade support 2, and the blade 1 is installed on the blade support 2. The other end 32 of the rocker arm can slide in the chute 51 provided on the cantilever bracket 5 . After calculating the buoyancy and moment of inertia according to physics, select a spring with an appropriate elastic coefficient. When the blades of the wind rotor rotate under the drive of the wind and the wind rotor reaches a ce...

Abstract

The invention discloses a power-constant output device of vertical-axle wind generator. It comprises a blade 1, a swing arm 3, a rotation axle 4, a suspending arm support 5, and a spring 6. Wherein, said swing arm 3 via rotation axle 4 is connected to the suspending arm support 5; the swing arm 3 can rotate horizontally around the rotation axle 4; one end (31) of swing arm is fixed on the blade 1; another end (32) of swing arm is fixed on one end (61) of spring on the suspending arm support 5. With said invention, the wind wheel can keep constant rotation speed when the wind speed is higher than rating one; the output power of engine can keep stably. The invention can improve the application value of vertical-axle wind generator.

Description

technical field [0001] The invention relates to a vertical-axis wind power generator, in particular to a constant power output device applied to a vertical-axis wind power generator. technical background [0002] In order to make better use of wind energy, people have designed various structural forms of wind power generators for a long time. According to the position of the wind turbine rotation axis in the space direction, it is divided into horizontal axis wind turbines in the horizontal direction and vertical wind turbines in the vertical direction. shaft wind turbine. [0003] Generally speaking, the wind rotor of the vertical axis wind turbine is composed of straight blades with a certain airfoil shape, and the axes of the blades are parallel to the vertical axis. The airfoil shape of the blade can be designed according to existing aerodynamic principles. According to the principle of aerodynamics, the line connecting the front and rear edges of the blade is called t...
