Embodiment Construction

[0111] like Figure 9 and Figure 17 Shown: the present invention has designed and used 9 sail type blades, the maximum vertical wind-receiving area of ​​each blade is 20 meters * 30 meters, the radius of the inner ring track is 15 meters, and the radius of the outer ring track is 36 meters. In canvas or any soft material, rated at 1.5 MW. Roller and track supports are added under the middle part of the cross-arm beam. The utilization coefficient of wind energy is greater than 0.9.

[0112] Cost comparison of wind turbines with the same power as the horizontal axis:

[0113] The following is the public information on the cost of wind turbines with the same power on the horizontal axis obtained from the Internet:

[0114] Take the 1.5MW wind turbine as an example.

[0115] 1. The weight of the tower is 130T to 150T, the price can be calculated, about 1.5 million.

[0116] 2. The control system is controlled by foreign manufacturers, about 500,000

[0117] 3. The hub and ...

Abstract

The invention discloses a self-control air blower or a wind driven generator and a manufacturing method thereof. The self-control air blower or the wind driven generator is characterized in that: a sensor is arranged on a wind wheel of the air blower or the wind driven generator; the sensor is connected with a self-controller; the self-controller is connected with a power mechanism; the power mechanism is connected with fan blades with adjustable wind area.

Description

1. Technical field [0001] The invention belongs to the technical field of wind energy utilization, and is especially applicable to the technical fields of wind power machinery and wind power generation. 2. Background technology [0002] With the rapid development of the world economy and fierce competition, new energy power generation technology, especially wind power generation technology, has attracted more and more attention from all countries in the world. At present, the installed capacity of wind power in the world has reached 4.9 million kilowatts, and it is still growing at an average annual rate of 60%, reflecting a new trend in the development of international electric power. my country has abundant wind energy resources, and foreign mature technologies can be used for reference. The conditions for large-scale development of wind power have been met and should be actively developed. However, at present, the high cost of wind power has hindered the further developm...
