Sectional view of the main state of operation of a wind turbine.

As shown, the vertical axis wind power generator of the present invention is largely installed to be rotatably installed in a pair of mounting frame (100a, 100b), each mounting frame (100a, 100b) is divided into one side and the other side By connecting the connecting shafts (110a, 110b), each of the connecting shafts (110a, 110b) to generate a rotational force by providing wind to concentrate towards the connecting shafts (110a, 110b) when the wind speed is a breeze, when the wind speed is a strong wind Wind vane cover (120a, 120b) and wind blade cover (120a, 120b) to control to minimize the damage to wind equipment by strong winds by blocking the wind transmitted to the connecting rotary shaft (110a, 110b) as much as possible Means for controlling to rotate.

First, the pair of mounting frames 100a and 100b are tubular bodies having a rectangular shape.

Each of the connecting rotary shafts (110a, 110b) is fixed to the wind blade (111a, 111b) is connected to the outer periphery, the fixing structure is inserted through the insertion hole in the center portion of the connector for connecting the wind blade (111a, 111b) It is formed and has a structure in which the connecting rotation shaft (110a, 110b) is interpolated and fixed to the insertion hole formed therethrough.

Here, the number of wind vanes (111a, 111b) can be used in a variety of applications, such as four, three or five, as shown in the figure, which is the average wind strength or wind power in the region where the vertical axis wind turbine of the present invention is installed Depending on the size of the wing (111a, 111b) is used for selective use.

The two wind vane cover (120a, 120b) is installed on each connecting rotary shaft (110a, 110b) divided into one side and the other side because both sides are the same, if only one wind blade cover (120a) will be described as follows same.

The wind blade cover 120a on one side has a cylindrical shape, and through-holes are formed on both sides thereof, and the front lower portion has an open shape. The ball bearings 121a and 122a are connected to the through-holes formed at both sides in an interference fit manner, and the connection rotating shaft 110a of one side is fitted through the connected ball bearings 121a and 122a.

The rod-shaped weight body 123a is connected and fixed through a fastening means such as a bolt along a lower outer surface of the wind blade cover 120a on one side, and an open lower portion of the wind blade cover 120a on one side. The wind direction concentration film 124a is extended and protruded in the cross section, thereby concentrating the wind blowing toward the front lower side toward the wind vane 111a fixedly connected to the connecting rotation shaft 110a, thereby providing a rotation speed per unit time.

That is, when the wind breeze (W1), which is the speed of the usual wind blows, the wind blade (120a) is not rotated by the weight body (123a) connected to the lower side, so that the blowing wind is opened under the wind blade cover (120a). Is concentrated through place. In other words, even if the breeze W1 strikes the wind direction focusing film 124a extended to the open lower end surface of the wind vane cover 120a, the strength of the wind speed is small and the weight body 123a is provided on the lower side. This is because the wind turbine blade cover 120a cannot be rotated and is concentrated toward the wind turbine blade 111a.

And when the wind breeze (W1) is the wind speed of the usual wind blows the wind breeze (W1) flowing into the wind blade cover (120a) to the outside to allow the wind blade 111a to rotate smoothly. The wind direction passage space 125a is provided on the rear surface of the wind vane cover 120a.

As such, one side of the connecting rotary shaft 110a fitted to the wind blade cover 120a on one side is internally rotated to one side of the mounting frame 100a. First, a ball bearing 101a is formed on one inner surface of the mounting frame 100a. The fastener 102a seated on the inner side is fastened through a bolt or the like, and one end of the connection rotating shaft 110a is connected to the other side of the mounting frame 100a on the other side of the mounting frame 100a. The fitting is connected to the ball bearing 101a, the other end is completed through the other ball bearing 103a through.

Here, the number of the wind blade cover 120a of one side connected to the inner surface of the mounting frame 100a of one side is connected to about 4 as shown in the drawing, but also in the size of the wind or wind device blowing in the installation area Various numbers can be applied accordingly.

Thus, through the wind vane cover (120a) connected to the mounting frame (100a) to move the wind vane cover (120a) provided with a weight body 123a on the lower side toward the wind vane cover (120a) by rainy season or typhoon. When the strong wind (W2) of the wind having a strong speed of the degree is blown wind cover 120a is connected to the rotating shaft 110a through a ball bearing (121a, 122a) is rotatably connected to the wind blade (120a) When the strong wind (W2) hits the wind direction concentrated film (124a) protruding to the cross section of the open lower portion of the wind vane cover (120a) is rotated in the clockwise direction of the traveling direction of the strong wind (W2).

For this reason, by minimizing the inflow of the strong wind (W2) to the open portion of the lower portion of the wind vane cover (120a) by the strong wind (W2) damaged the wind vane (111a) provided in the interior of the wind vane cover (120a). Can be prevented.

The other side of the mounting frame (100b) is connected to the wind blade cover (120b) of the other side as described above to complete the connection of the wind cover (120a, 120b) to the mounting frame (100a, 100b) of each side.

Then, each connecting rotary shaft (110a, 110b) through and exposed through the other side of the mounting frame (100a, 100b) on both sides to the one-way bearing (181a, 181b) fixedly connected to the inner side of the idle guide pipe (180a, 180b). Connect Here, the one-way bearing (181a, 181b) is provided to be rotated only in one direction, in this case, when the connecting rotary shaft (110a, 110b) is rotated in the clockwise direction to rotate together with the connecting rotary shaft (110a, 110b), When the rotary shafts 110a and 110b rotate in the counterclockwise direction, the connecting rotary shafts 110a and 110b are idle.

As such, the reason for connecting the idling induction pipes 180a and 180b provided with the one-way bearings 181a and 181b to the connecting rotary shafts 110a and 110b is that the wind covers all the wind vane covers 120a and 120b vertically stacked. In this case, the wind vanes 111a and 111b provided in the cover 120a for each wind vane rotate in a clockwise direction, which is a rotational direction necessary for power generation, and a connecting rotary shaft in which the wind vanes 111a and 111b are fixedly connected ( 110a, 110b also rotates in a clockwise direction. At this time, the one-way bearing connected to the connecting rotary shafts 110a and 110b rotates together with the connected connecting shafts 110a and 110b to rotate together in a clockwise direction, thereby rotating the power relay shafts 150a and 110b. It delivers rotational power that can generate power to 150b), maximizing electricity generation efficiency.

On the other hand, only part of the wind vane covers 120a and 120b stacked vertically (for example, two upper wind vane covers) blows the wind, and the other part (for example, the lower two wind vanes). Cover), when the wind is not blowing, the power relay shaft (150a, 150b) is rotated by the rotational force transmitted from the upper two wind blade cover, but the connecting rotary shaft of the lower two wind blade cover that does not receive the wind transmission Does not rotate and rotates relatively counterclockwise. At this time, however, the one-way bearing connected to the connecting rotary shaft improves power generation efficiency because the connecting rotary shaft does not transmit the rotational force to the connecting rotary shaft by idling when the connecting rotary shaft rotates counterclockwise.

Thereafter, one side of the bevel gears 130a and 130b is fixed to the outside of the idle induction pipes 180a and 180b, and one side of the bevel gears 130a and 130b is connected to the other bevel gears 140a and 140b. In addition, the power relay shafts 150a and 150b are penetrated to the other bevel gears 140a and 140b.

Here, each of the power relay shaft (150a, 150b) is securely connected to the upper end facing each of the mounting frame (100a, 100b) so that it can be connected and rotated firmly, the bottom of the protruding fixed connector After the ball bearings are fixedly connected, the power relay shafts 150a and 150b are inserted into the ball bearings of the fixed connecting rods.

Each of the power relay shafts 150a and 150b rotates in opposite directions so that the power relay shafts 150a and 150b are connected to the differential gear unit 160 so that they may rotate in one direction. The differential gear unit 160 connected to each of the power relay shafts 150a and 150b is connected to the generator 170 again to generate electricity by power from the rotational force transmitted from the differential gear unit 160.

Although not shown in the drawings, a capacitor may be connected to the generator 600 through a wire to provide electricity to be generated.

As such, the ball bearing 320 is inserted into the outer periphery of the assembled vertical shaft wind power generator in the state in which the fixed shaft 300 is fixed to the ground in order to be able to rotate along the direction of the blowing wind. A rotating tube 310 is covered with the fixed shaft 300 in which the 320 is fitted. Thereafter, the plurality of reinforcing connecting rods 361, 362 and 363 are connected and fixed between the rotating tube 310 and the mounting frames 100a, 100b and 200 on both sides thereof.

In addition, when the wind blows in any direction by fixedly connecting the wind direction moving membrane 330 having a cramp shape in front of the rotating tube 310, the rotating tube 310 rotates along the wind direction, in particular, the rotating tube ( By the wind hit the wind direction moving membrane 330 fixed to the front of 310 is provided so that the mounting frame (100a, 100b, 200) of both sides can be rotated in the direction of the blowing wind.

And using the support frame 370 to the rotatable tube 310 to fix the mounting frame support loop rail 340 to the rotatable tube 310 so as to rotate smoothly while supporting the mounting frame (100a, 100b) of both sides rotating in the wind direction. The rail wheels 350 are attached to the lower surfaces of the mounting frames 100a and 100b on both sides, and the rail wheels 350 attached to the mounting frames 100a and 100b on both sides are supported by the mounting rails 340. Provide for rotation along the way.
