Description

Wind power generator using lift force

The present invention relates to a lift wind turbine, and more particularly, in order to effectively use the wind power difference according to the altitude, after the initial takeoff of the wind turbine with a lifting flotation, such as a mechanism, in particular horizontal and vertical power generation unit While the wing generates lift, the wind power generator takes off at high altitude and airs, while the ultra-lightweight horizontal and vertical power generation parts maintain the equilibrium stability by the rotational inertia action of the first and second permanent magnet rotor wheels rotated by the wing. To control the horizontal and vertical power generation units by reliably using the wind power (wind) with a wind speed of 30m / s and releasing or rewinding a plurality of ropes. Lifted wind power generator that maximizes air space, stability and power generation efficiency by making it simple It relates.

In general, certain devices of mass and volume must have a constant lift to fly in the high altitude winds of the earth, and must be fixed by ropes connected to the ground to stabilize and stabilize them. In other words, a particular device must be able to overcome the total weight (weight), including the weight of the rope itself and the weight of the device constituting the device, and the drag (wind resistance) against the specific device. Therefore, under these conditions, to lift a certain device while ensuring equilibrium stability, lift force that can offset gravity is required, and a tension above the drag component caused by wind is required.

Currently, levitation wind power generators or aerial wind power generators using existing mechanisms rely on limited lift, and thus face a lot of cost and low efficiency in airing power generating units and transmission lines constituting specific devices. Therefore, in order to expand the power generation capacity, it is necessary to make the specific device (generator) larger and to generate its own lift, and to optimize the balance stability.

Conventional vertical and horizontal wind power generators are being enlarged to maximize the wind power difference (generally the wind increases with the height from the ground) and the demanding location conditions and wind power, considering the wind direction, environment and power generation capacity. .

However, due to the huge size, environmentally negative effects such as increased installation costs, difficult installation in mountains and seas, difficulty in maintenance due to large wind turbines, noise caused by the rotation of several tens of meters, and visual discomfort It is pointed out.

On the other hand, the air linear power generation system disclosed in Korean Patent Publication No. 10-2006-0114773 and the tube support body disclosed in Korean Patent Registration No. 10-0886214 have limited buoyancy such as airships and tubes (mechanisms). Depends on Therefore, the total weight of the generator, such as the generator weight, the accessories attached to the ground, and the control lines connected to the ground, has a large limit of the floatation power to maintain the equilibrium stability of the generator and continuously generate electricity in high wind areas of several hundred meters above the ground. There is a problem.

In addition, the air wind power generator disclosed in the Republic of Korea Patent Publication No. 10-2009-0021300 is said to increase the altitude of 15000 ~ 40000 feet tropospheric jet airflow region by the lift by the airfoil (wing), which increases the length of the transmission line up to 15000 ~ 40000 The problem of having to secure the pit (4.5km ~ 12km) and the increase in the total weight of the power generation device by the transmission line has a problem that ignores the limit of lift generated by the non-powered airfoil (wing).

The “airborne wind turbine,” developed by Canada's “Magen Power Company”, is a balloon that is blown with helium, flying over 300m. However, in the case of wind power that rotates a helium mechanism (balloon) -type turbine at high altitude, the helium mechanism that rotates while traveling in a high altitude wind zone also has problems in horizontal stability and equilibrium stability. That is, there is no self-raising, there is a limit in the rotational speed due to the relatively thick body and wings, it is difficult to secure the balance stability by causing vibration or deformation of the helium mechanism turbine during rotation.

In addition, the existing air linear power generator, the aerial wind power generation system using the tube support and the aerial wind power generator has a problem that can not achieve the equilibrium stability itself in the process of the power generator is suspended in the air. In other words, only the rope connected to the ground ensures the stability of the equilibrium. This is a difficult problem to adjust the instability generated in the high altitude wind zone on the ground hundreds or several meters away.

In addition, the existing air linear power generator, the aerial wind power generation system using the tube flotation, the aerial wind power generator is fixed to the ground connection frame. That is, there is a problem that the ground connection rope and the transmission line may be twisted due to a gust generated at high altitude.

Therefore, an object of the present invention, which was created to solve the above-mentioned conventional problems, in the present invention, when the wing of the horizontal and vertical power generation unit that is about 100 ~ 300m from the ground rotates by wind, the upper part of the wing The higher the wind speed, the lower the air pressure, and the lower the wing, the higher the air pressure, so that the “magnus” effect, lift, can be used to support the wind turbine, while the rotational force of the horizontal blades is horizontal.

Hereinafter will be described the operating state of the wind turbine generator according to the present invention.

The wind power generator according to the present invention is installed by moving to a flat, meadow, coast, sea by any vehicle that can be mounted, that is, a truck, a ship.

Early takeoff of the wind turbine according to the present invention, if the base 10 is fixed to the anchor bolt (not shown), the wind turbine is lifted from the ground by the lifting support (15, 15 ') Take off early. That is, the lift body (15, 15 ') is the wing 16, 16', 46, 46 'installed in the horizontal and vertical power generation unit 20, 40 is rotated by the wind to generate the lift By raising itself to the direction of the wind, it lifts the wind turbine by several meters.

Therefore, the lifting force of the lifting flotation should be such that the early take-off of the lifting flotation wind power generator can be prevented and the sudden fall.

The wind power generator, which has risen to an altitude of about 100 to 300 m, airs while continuously generating lift by the rotation of the blades 16, 16 ', 46, 46'. The horizontal stability is maintained by the rotation lift generated by the rotation of the first and second permanent magnet rotary wheels 34 and 45. Then, if a change occurs in the equilibrium state under the influence of a gust, etc., it is adjusted by a plurality of ropes 14 'and 14 "wound on the roller 14 on the ground. In the state installed on the vertical axis 11, the plurality of ropes 14 ', 14 "and the like are prevented while being rotated 360 degrees.

The power generation production of the wind power generator according to the present invention will be described. First, the power generation production of the horizontal power generation unit 20 will be described, and since only the eccentric weight 22 has the same configuration and is configured to perform the same operation, only one of these operations will be described.

Therefore, when the first permanent magnet rotor wheel 34 rotates, and the first permanent magnet 33 attached to the first permanent magnet rotor wheel 34 rotates, an induced current is formed. That is, as the first permanent magnet 33 rotates, the magnetic force is alternately applied to the first and second cross metal plates 30 and 32 between the first and second cross metal plates 30 and 32. Produce electric power by forming an induction current in the first coil 31 provided in the. Here, the first and second cross metal plates 30 and 32 serve to induce electromagnetic force by keeping the direction of the magnetic force and the direction of the first coil 31 at right angles. Thus, the produced electricity is stored in the capacitor 25 along a wire (not shown).

On the other hand, when the wing 46 of the vertical power generation unit 40 rotates from the initial takeoff, the second permanent magnet rotating wheel 45 is rotated. Accordingly, when the second permanent magnet rotating wheel 45 rotates, and the second permanent magnet 44 attached to the second permanent magnet rotating wheel 45 rotates, an induced current is formed. That is, as the second permanent magnet 44 rotates, the magnetic force is alternately applied to the N-pole and the S-pole to the "c" shaped metal plate 42 to induce a current to the second coil 43 provided on the "c" shaped metal plate 42. Produce power generation. Here, the "c" -shaped metal plate 42 serves to induce electromagnetic force by keeping the direction of the magnetic force and the direction of the second coil 43 at right angles. Thus, the produced electricity is stored in the capacitor 25 along a wire (not shown). In addition, the vertical power generation unit 40 absorbs the front and rear vibrations generated by the wings 16 and 16 'of the horizontal power generation unit 20 connected horizontally to the plurality of ropes 14' and 14 ". Blowing at high altitude, turning to the rotational force on the blades 46, 46 'that rotate with strong winds, increase the rotational force.

When lowering the wind power generator according to the present invention, by using the electric motor 100, etc. installed in the roller 14, a plurality of ropes (14 ', 14 ") can be wound on the roller 14 and lowered to the ground. have.
