Problems solved by technology

However, in the current wind power generation technology, to control the speed of the wind power generator, it is necessary to measure the speed of the wind turbine first, and then feed back the electromagnetic signal that the generator has exceeded the speed to the generator speed control system, which will do work to regulate the speed of the generator. The technical structure of the speed measurement and control system is complicated and the cost is high

Embodiment Construction

[0021] As shown in Figure 1: the wind wheel shaft 1 is fixedly connected with the wind blades 2 to form the wind wheel. The wind blade surface is perpendicular to the horizontal plane, and the horizontal height of the wind wheel 2 is constant when rotating; the 2 is no less than four pieces, and they can be straight plates or curved plates. The upper end of 1 is connected to the circular top cover 3-1 through a bearing, and 1 is connected to the circular bottom cover 3-2 through a bearing downwards, and 1 is connected to the transmission 4 through 3-2 downwards, and 4 is connected to the generator 5. At the center of 3-1, a bearing is connected to the wind plate rotating shaft 6, and the axis of 6 is perpendicular to 3-1 and intersects with the center of circle of 3-1. There is a rain cover7.

[0022] The main wind plate 9-1 is provided to connect with the set main wind deflector 11-1 through the set main wind plate support 10-1, and the 10-1 is connected to the 6 through the...

Abstract

The invention relates to an elastic speed control wind power generator which belongs to the field of wind power generators. A wind wheel shaft is connected with a wind blade and connected with a power generator by a transmission; a main wind guide plate and an auxiliary wind guide plate are connected with a main wind blocking plate and an auxiliary wind blocking plate by a main wind plate bracket and an auxiliary wind plate bracket which can rotate; an included angle between the lee surfaces of the main wind guide plate and the auxiliary wind guide plate is smaller than 180 DEG; the wind direction can be automatically searched by the wind force, one half of the windward surface of the wind wheel is always blocked by the main wind blocking plate and the auxiliary wind blocking plate, and the other half is blown; deforming elastic devices are arranged on the lee surfaces of the main wind guide plate and the auxiliary wind guide plate; adjustment and control on the rotating speed of the power generator are realized by utilizing the inherent elasticity of natural wind and a solid substance without the work application of a velometer and other power sources; the power generator has stable rotating speed, simple technical structure, low manufacture cost as well as high wind energy utilization ratio and generating efficiency; and the wind blade surface is perpendicular to the horizontal surface.

Description

Technical field: [0001] The invention relates to a device for generating electricity by wind power, which belongs to the field of wind power generators. technical background: [0002] At present, in the field of wind power generation technology, the magnitude of the wind power and wind speed due to the wind energy formed by nature is uncertain, that is, it changes; and the speed of the wind power generator should be kept within a set relatively stable range according to the design technical requirements Inside. However, in the current wind power generation technology, to control the speed of the wind turbine generator, it is necessary to measure the speed of the wind turbine first, and then feed back the electromagnetic signal that the generator has exceeded the speed to the generator speed control system, which will do work to regulate the speed of the generator. The technical structure of the speed measurement and control system is complicated and the cost is high. Inve...
