In general, wind power is a pollution-free energy source in a natural state, which is the most economical energy source among alternative energy sources. Currently, wind power generation using such wind power converts the power of the wind into the rotational force. It is a technology that directly supplies power generated by converting to power system or consumer. If such wind power is used, the efficiency of land use can be improved by utilizing sites such as mountains, coastal backcountry, and embankments.

Meanwhile, the wind power generator refers to a device that converts wind energy into mechanical energy using various types of windmills (propellers) and drives power generators to obtain electric power.

Wind power generation using this wind power generator is powered by wind, which is infinitely clean energy, and thus has no pollution such as heat pollution, air pollution, and radiation leakage due to heat generation, unlike conventional generation methods using fossil fuel or uranium. to be.

Because of these advantages, wind power systems are recognized as the most viable alternative energy sources, and wind power systems of around 32,154 MW (total 2002) are already being installed and operated worldwide. Among them, the capacity of wind power system installed in 2002 was 7,227MW, which is larger than the capacity of nuclear power plant built that year.

Korea also has a strong interest in wind power generation systems in order to cope with changes in the international environment such as the World Climate Change Convention, rising oil prices, and realistic problems that depend on imports for 96% of domestic energy use. In addition, the introduction of wind power generation systems has recently increased dramatically because the structure or installation is simple, so that it is easy to operate and manage, and unmanned and automated operation is possible.

However, the conventional wind power generator can theoretically convert only about 60% of the kinetic energy into electrical energy, which can only be used as electrical energy in consideration of mechanical friction and generator efficiency.

First, the power generating unit 100 serves to generate power by rotating by the wind, the propeller 110 and the propeller 110 to rotate by the wind is rotated by fitting the rotating shaft 130 And, it is composed of a wind blowing device 120 is fitted to the front rotation shaft 130 of the propeller 110.

At this time, the propeller 110 has a coupling ring 112 is installed in the center portion to be fitted to the rotating shaft 130, the coupling shaft 114 is formed on the outer peripheral surface of the coupling ring 112, each propeller The wings are configured to be fitted to the coupling shaft 114, the coupling ring 112 is inserted into the rotary shaft 130 and then coupled by a coupling means such as a bolt.

On the other hand, the wind collecting device 120 serves to collect the surrounding wind, the coupling ring 122 is installed in the center to be fitted to the rotary shaft 130, as in the propeller 110, the coupling ring A plurality of reinforcing members 124 are formed on the outer circumferential surface of the 122 and are coupled to the inner circumferential surface of the wind collecting device 120. In addition, the wind collecting device 120 is formed so that the front portion is wider and the inner diameter is narrower toward the rear, that is, the direction in which the propeller 110 is installed, increase the flow rate of the wind passing through the wind blowing device 120 propeller 110 To increase the speed of rotation.

A wing attachment portion 126 is formed at the front portion of the wind collecting device 120, that is, the outer periphery of the inlet portion where the wind enters, so that a plurality of wings 128 may be coupled to the wing attachment portion 126. At this time, the wing 128 is to serve to rotate the wind collecting device 120 in response to the wind is preferably coupled to be detachable using a coupling means such as a bolt.

In addition, the wings 128 may be variously deformed and coupled according to the size of the wind collecting device 120 and the desired power generation amount, it is preferable to install 8 to 12 at regular intervals in the wing attachment portion 126. Do. The reason is that if less than eight wings 128 are installed, it is difficult to obtain the desired rotational force, and if more than 12 are installed, the weight is much higher, so the rotational efficiency is lowered.

Therefore, the wind collecting device 120 is coupled to the front rotation shaft 130 of the propeller 110 to collect the surrounding wind primarily to increase the rotational speed of the propeller 110, the front (inlet) in the rear The inner diameter is narrowed toward the (outlet) side to increase the flow velocity of the wind passing through the wind collecting device 120 to secondaryly increase the rotational speed and at the same time a plurality of wing attachment parts 126 formed on the outer periphery of the front part. By installing two wings 128 so that the wind collecting device 120 itself is to rotate to maximize the rotational force to significantly increase the power generation efficiency.
