At present, Korea is accelerating the development of localization with the aim of securing technological independence of wind power generators. Many studies are actively conducted by many national institutions, research institutes, manufacturers and construction companies. As a result, prototypes equipped with advanced systems have been produced and international design certification has been achieved.

The existing medium and large wind power generators developed so far have a starting wind speed of 3 m / s, a rated driving wind speed of 12 m / s, a stationary wind speed of 25 m / s, and a limit breaking wind speed of 70 m / s. It is economical only when it is at least 5.6m / sec, and the wind speed area below it is not economical at all. In addition, in order to generate 200KW, the minimum wind speed should be 12m / sec, and at the wind speed of 5.6m / sec, power generation of 50 ~ 60KW is possible. In addition, not only 59.3% is proved to be the maximum power generation efficiency by Betz's law, but also friction, voltage conversion, and storage by gears during the process of converting wind energy into electrical energy. Loss occurs, the actual conversion efficiency is only 10-30%.

(Note: With regard to the efficiency of converting wind energy into rotational kinetic energy by the blades of the wind generator, to use 100% of the energy of the wind flow, the kinetic energy of the wind ends up at zero. The wind generator completely blocks the flow of wind, so there is no place for the wind to go (that is, no wind can enter the wind generator).

On the contrary, as described in the preceding paragraph, the wind energy (proportional to the third power of the wind speed) is as small as possible. It is desirable to pass through a wind generator. In other words, the theoretical interpretation of the most efficient conversion of wind energy into kinetic energy shows that the maximum efficiency at that time is about 59.3% It is proved. This is called Betz's law (Bets's limit).)

Especially in Korea, except for a few places, the average annual wind speed is less than 5.6m / sec, so the annual average operation utilization rate of new wind power generators is very low.

In order to improve the efficiency of wind power generation, a power generation loss-free generator using a multipole synchronous generator and a power converter in a direct drive wind power generator without a gear is also an alternative. Existing wind power, which is proportional to the third power of silver wind speed, is so low efficiency that 4 to 5 power wind turbines of high efficiency should be invented.

And the existing wind power generator protects the wind power generator by allowing the blade to be folded when reaching the destructive wind speed due to the excessive wind speed caused by typhoons. Axles), Nacelle (engines of airplanes and airships [cargo, crew] room) and generator tower bodies are exposed to excessive wind speeds.

In addition, the device for reducing the amount of rotation of the blade when the wind speed is also excessive because the way the blade is folded in the opposite direction of the wind, there is a problem that there is a high probability of failure due to the number of operating parts.

In particular, during the maintenance of the existing wind power generator, such as failure, inspection, replacement of consumables, and lubrication, it is difficult for the worker to climb to the high wind power generator on the ground, and the equipment for maintenance is more difficult to climb. In addition, since the wind power generator is mainly installed on the coast, island or mountain area, there is a problem that it is impossible to use a device such as a cargo crane.

The present invention overcomes the limitations of the above-mentioned wind power generation efficiency and increases the rotational force of the wind turbine rotating blade to enable high-efficiency power generation. Its purpose is to protect the wind power generator by reducing the rotational speed of the blade with little movement during excessive wind speed.

Hereinafter, the configuration of the present invention according to the accompanying drawings in detail as follows.

The present invention is constructed as shown in Figure 1, each part is a wind collecting device 101, pressurizing device 102, air blowing device 103, blade 104, wind direction wind speed tracking device 105, power generation and An electrical storage device 106, a multi-stage hydraulic device 107, and a control unit 108 are configured.

As shown in FIG. 2, first, the wind collecting device 101 will be described. The eight wind pressure collecting guide partition walls 201 are located below the wind power generator 109, and thus the wind direction detected by the wind direction wind speed tracking device 105. And when the wind speed or more is detected based on the wind speed information, the partition motors 202 and 203 are driven to move the partition wall 201 in the direction upward. As shown in FIG. 2_A, the partition wall 201 includes threaded pitch shafts 204 and 205 on the inner side and the outer side of the partition 201 so that the respective shafts 204 and 205 are partition walls 201. Rotation at an appropriate speed for the vertical movement of the partition wall 201 was installed so that the vertical movement without receiving any resistance. The partition motor outer side 203 rotates the shaft 205 at the top of the screw pitch shaft outer side 205 and the partition motor inner side 202 is at the lower portion of the screw pitch shaft outer side 204. Rotating partition 201 was able to move up and down with a strong force. The partition motors 202 and 203 receive and drive a signal transmitted from the controller 108 to rotate the inner and outer shafts 204 and 205, and the partition wall having a pitch 206 corresponding thereto is formed. 201 is moved to the upper side, and the wind is gathered with a strong force, as shown in FIG. 2_B, to open the damper (207) and to gather in the pressure chamber (209) inside the generator POLE (208). The damper 207 is equipped with a wind pressure weakening reaction type spring 210 to open automatically when the wind collected by the partition wall 201 is a proper wind pressure. The partition wall 201 collects the wind in the left and right directions to the center, and the vertical partition wall 211 collects the wind in all directions in the vertical direction, so that the wind in all the directions is increased without loss. The density of the metal was increased to be supplied to the pressure chamber 209 inside the POLE 208. In addition, when the wind direction and wind speed change, the wind direction wind speed tracking device 105 detects and transmits a signal to the control unit 108. The control unit 108 analyzes the signal and then supplies the signal and power to the partition wall motors 202 and 203. By supplying and driving the barrier rib 201 previously moved to the upper portion to move downward and at the same time to move the barrier rib 201 in a new direction. In particular, during excessive wind speeds such as typhoons, the partition wall 201 is located at a lower portion with a relatively small air volume than the upper portion, and the wind generator 109 is damaged by allowing excessive wind to easily pass through the upper portion where the damper 207 is located. To prevent it. In addition, as shown in Figure 2_c, the tower support pillar 212 is fixed to the bulkhead Shanghaidong guide guide 213, it was installed to serve as a pillar to support the load on the wind turbine 109, where the tower support The “c” shaped bulkhead shangdong guide guide 213 formed on the pillar 212 prevents the bulkhead 201 from escaping from the pitch 206 due to the rotation of the screw pitch shafts 204 and 205. In addition, the partition motors 202 and 203 are protected from damage and contamination due to external weather environment, and the motors 202 and 203 are rotated by the rotational force when the partition motors 202 and 203 rotate. A motor protector 214 is provided which can fix the motors 202 and 203 so that the shafts 204 and 205 can rotate normally without rotation.

As shown in FIG. 3, the pressurizing device 102 will be described below. As described above, when the air having a higher density is supplied to the pressure chamber 209 inside the POLE 208, the lower space inside the POLE 208 is blocked, so that the air blower 101 moves upward. By 301, the density is further increased to move to the air blowing device 103, which will be described later in a high pressure state. Here, the rotational force of the jet fan 301 is generated by the conical wind vane 302, the conical wind vane 302 is rotated by the wind, thereby transmitting two power attached to the lower portion of the wing 302. The dragon shaft 303 rotates around the POLE 208. At this time, due to the shanghaidong (described later) of the conical wind vane 302, the power transmission shaft 303 is also moved up and down, regardless of the shangdongdong without losing the rotational force of the power transmission shaft 303 The bearing 305 was provided so that it could be transmitted to the rack gear 304. Then, the rack gear 304 is connected to the speed increase gear 306 for the high speed rotation of the jet fan 301, and the power is transmitted to the speed increase gear 307 inside the POLE 208, and then inside the POLE 208. The jet fan rotary gear 309 for finally rotating the jet fan 301 via the rec gear 308 is rotated. As a result, the rotational speed of the relatively small jet fan 301 is increased through the multi-speed gear, compared to the rotational speed of the relatively large conical wind blade 302, so that the jet fan 301 rotates at high speed. Therefore, the air supplied at high pressure from the outside was compressed to a higher density. And, as shown in Figure 3_a, in order to protect the conical wind vane 302 in the case of excessive wind speed, such as typhoon, by installing the Shanghai-dong motor 310 and Shanghai-dong screw pitch shaft 311, as described above, When the wind speed measured by the wind direction wind speed tracking device 105 exceeds a predetermined amount, the shandong copper screw pitch shaft 311 is rotated by driving the shandong copper motor 310, and the conical wind blade frame 312 due to the rotation. By the pitch (314) of the frame auxiliary plate 313 attached to the conical wind vane 302 was arranged to conceal the empty space of the upper and lower partitions 211 described above. At this time, even if the conical wind vane 302 is concealed, the upper portion of the wing 302 is exposed to the wind is rotated by excessive wind speed, in order to prevent this, the solar panel 315 on the upper portion of the conical wind vane 302. Was installed. The solar panel 315 serves to protect the conical wind vane 302 even during normal operation, and to increase power generation in addition to the wind by the solar panel 315. The solar panel 315 is in close contact with the conical wind blade frame 312 so as not to be easily dropped by the wind, the shape of the solar panel 315 is not flat plate (flat edition), similar to the cauldron lid, streamlined In addition, the horizontal resistance is less generated by the wind and lift is not generated, as well as the conical wind vane 302 has been applied to further concealed by the force to be lowered more secure device. In addition, the above-mentioned external screw pitch shaft 205 for the partition wall is installed through the solar panel 315, so that the bearing 316 is mounted on the solar panel 315 so that each movement is not interfered with each other. The conical wind vane 302 and the external threaded pasha shaft 205 for the partition wall were provided so as not to collide with each other. Shanghaidong motor 310 is not damaged or contaminated by the external weather environment, as well as the Shanghaidong screw pitch shaft 311 does not rotate to prevent the phenomenon that the Shanghaidong motor 310 rotates ( 317 and motor support frame 318 were installed.

As shown in FIG. 4, the air blowing device 103 will be described. The air compressed at high pressure by the jet fan 301 continues to move upward along the POLE 206 and is divided into two branched pipes. It is supplied to the nacelle (402) through 401. This branch pipe 401 not only provides passage of compressed air 403 as described above, but also serves to safely transmit heavy loads of the blade 104 and Nacelle 402 to the POLE 206. . As shown in FIG. 5, the compressed air 403 thus supplied is supplied to each blade 104 through the hub 501, and finally blown out to the outside through the air outlet 502 at each blade 104. It was set up to. The blade 104 is designed to give an optimum rotational efficiency by horizontal wind as with the blade 104 of the conventional wind turbine, and can have a higher rotation speed and rotational force due to the air ejection. It was installed so that.

As illustrated in FIG. 5, the power generation and charging device 106 will be described. When the blade 104 in both directions rotates rapidly by the above-described method, the main shaft 601 rotates. Accordingly, the rotating shaft is vertically converted by the bevel gear 602 so that the power generating shaft 603 rotates. (See FIG. 4) The power generating shaft 603 is a rotational operation separate from the above-described jet fan 301, and is located at the center of rotation of the jet fan 301, but is mounted with the bearing 604 (see FIG. 3). It does not affect the rotation of the jet fan 301. The power generation shaft 603 is connected to the generator 605 located under the POLE 206 to produce power and store the power in the storage battery 606. In addition, even when the POLE 206 is finely bent by the strong wind pressure and the long power generation shaft 603 is finely bent, two refractive joints ( 607). As shown in FIG. 7, the articulation joint 607 is provided with a joint 701 so as to be transmitted without loss of rotational force even when the angles of the upper and lower rotation shafts do not coincide with each other. Thus, the rectangular spline 702 was mounted so that the rotational force was not lost at all by external factors. A universal joint 608 is installed at the bottom of the power generation shaft 603 to prevent damage to the internal shaft 609 of the generator mounted on the generator 605 even if the angle of the power generation shaft 603 is changed. The generator 605 was installed to protect it.

As illustrated in FIG. 6, the multi-stage hydraulic apparatus 107 will be described. The wind turbine 109 may be destroyed, as well as during maintenance work such as failure, inspection, replacement of consumables, and lubrication of the wind turbine 109. It is a device that can lay the wind generator 109 to the side in case of excessive wind speed. Since the lower portion of the wind power generator 109 is a square, the hinge 801 is installed on one side so as to achieve a fixed point when the wind power generator 109 is laid down. The hydraulic cylinders 802 and 803 are composed of two stages, and one stage is equipped with a plurality of hydraulic cylinders 802 and 803 to move the load of the heavy wind power generator 109. As shown in Fig. 9, during the laying down operation, the first stage hydraulic cylinder 802 at the lower side is operated first to lay down the wind turbine 109 by 45 degrees, and then the second stage hydraulic cylinder 803 at the upper stage is operated. It was set up so that it could be laid down by 90 °. This compresses the hydraulic oil which is normally stored in the hydraulic oil tank 804 to the hydraulic pump motor 805 and supplies the hydraulic cylinders 802 and 803 through the hydraulic hose to slowly wind turbine 109 with a strong force. It is designed to enable the lay down operation. The multi-stage hydraulic system 107 is installed together with the wind generator 109 concrete foundation 807 at the bottom of the ground line 806, so that it is not exposed to the outside during normal operation, such as weather environment or artificial manipulation. The device was installed so that a failure of the device would not occur due to a factor.

As shown in Fig. 7, the cross section of the blade 104 is designed in a streamlined manner so that lifting force is generated by wind pressure, so that the blade 104 is rotated by the wind in the horizontal direction. In the above manner, the air compressed at high pressure was injected through the air jet 502. This is to increase the rotational amount and rotational force of the blade 104. In addition, when the rotational speed of the blade 104 reaches the breaking speed, the wind pressure valve 902 is automatically opened by matching the wind pressure received by the front portion of the blade 104 with the limit pressure of the wind pressure regulating spring 901 to open the blade 104. Was set so that the rotational speed of the blade 104 was not increased any more by receiving a large resistance.

As shown in FIG. 8, a wind direction wind speed tracking device () is mounted on the upper portion of the wind power generator 109 to measure wind direction and wind speed in real time to transmit data to the control unit 108 located below the wind power generator 109. It was. As described above, the controller 108 receives the data, analyzes the current wind direction, and transmits a driving signal to the corresponding partition motor 202 appropriate to the direction to move the wind pressure collecting guide partition wall 201 upward. Compressed air was collected in the damper 205, and if the wind speed exceeded the breaking wind speed by detecting the current wind speed, the conical wind vane 302 was concealed and the partition wall 201, which was raised to the position of the damper 205, was raised. All of them were moved to the lower side so as not to be damaged by the breaking wind speed.

The configuration of the present invention is to overcome the limitations of the existing wind power generators by Betz (Betz's law) to enable a high efficiency wind power generation. It uses high winds at the bottom of the blades to pressurize the air to increase the rotational speed and rotational speed of the blades, thus producing more efficient power than any blade ever developed.

In addition, the braking device of the blade is a method of generating air resistance to the blade to create a resistance, so that a large deceleration function can be implemented with less operation, so that the failure is less and efficient deceleration is possible. In addition to maintenance work such as failure, inspection, replacement of consumables and lubrication of wind power generators, wind power generators can be laid on the side in case of excessive wind speeds that can destroy wind power generators. It is effective to operate.
