Description

  The present invention relates to a wind turbine structure of a wind power generator, and in particular, can reduce the speed of a wind turbine and a rotating shaft, can prevent damage to the generator due to excessive high-speed rotation, and can be rotated with a wind turbine by storing or deploying multiple blades of the wind turbine. The present invention relates to a wind turbine structure of a wind power generator that achieves the purpose of controlling the rotational speed of a shaft and preventing an excessively high speed operation of the generator, has a simple structure, is easy to maintain, is quick to start, and has high power generation efficiency.

As electricity usage continues to increase around the world, calls for power saving and energy saving are intensifying. On the other hand, in addition to power saving, a new power supply system is being developed actively.
In general, in addition to nuclear power generation and thermal power generation, hydroelectric power generation using natural energy, solar power generation, wind power generation, and the like are being promoted.

  Among them, wind power generation is to generate and store electricity by rotating fan blades with wind power and driving the operation of the generator. The fan blades for wind power generation must be adapted to the wind direction so that the fan blades rotate by receiving wind force and can be linked to the operation of the generator, so that the wind blades become headwind. However, since the wind direction changes depending on factors such as weather conditions, seasons, and the environment, generally, a large windmill used for wind power generation has a cross-shaped knife-like fan blade installed at the top of a high-pitched column. However, installation is not widespread because it has problems such as being large, expensive, difficult to install, and unable to change direction.

  In general, a fan blade for performing wind power generation has a fixed type and is installed in an annular shape outside the central rotation shaft, and the angle of the fan blade is also fixed and cannot be adjusted. Therefore, even if the wind force or the wind direction changes, the fan blade cannot be changed in accordance with the wind force and the wind direction.

  As shown in FIG. 8, the current wind power generator A is provided with a plurality of fan blades A2 outside the center rotation axis A1. The central rotary shaft A1 and the plurality of fan blades A2 are connected using a weight bar A3 and a support bar A4. When the plurality of fan blades A2 rotate, the support rods A4 are pulled and the weight rods A3 are raised in conjunction with each other, thereby moving the plurality of fan blades A2 outward. However, since each support bar A4 and the weight bar A3 are vertically connected to each other in the vertical and horizontal directions, once the operation is stopped and the operation is stopped once, the plurality of fan blades A2 are not operated. The rotation must be restarted, which consumes a lot of power. Further, if the number of restarts is large, the operation of the central rotary shaft A1 and the generator A is likely to be unstable, and a failure situation is likely to occur.

Furthermore, the following drawbacks exist during actual operation.
1. Since the plurality of fan blades A2 used by the wind power generator A are positioned perpendicular to each other by the weight bar A3 and the support bar A4, when the fan blades A2 move outward, The situation is likely to occur. Thereby, each fan blade A2 cannot be opened or stored, and the center rotation axis A1 cannot be decelerated. For this reason, the rotation of the fan blade A2 and the central rotary shaft A1 tends to be excessively high, and the generator A is broken or damaged.
2. When the weight bar A3 is pulled by the support bar A4, it draws an arc, swings upward, rises, and opens between the weight bar A3 and the support bar A4 at a certain angle. For this reason, at the time of deployment or storage, resistance to clogging or catching is likely to occur, and the support bar A4 is not easily moved by the fan blade A2, and the support bar A4 or the fan blade A2 is likely to be damaged. Moreover, the structure is complicated and maintenance is difficult.
That is, as described above, the fan blades of current wind power generators have the difficulty and hassle that storage and deployment control is not easy. In addition, since the rotational speeds of the fan blade and the central rotating shaft cannot be reduced, there is a disadvantage that excessively high speed rotation occurs and the generator fails.

  In view of this, the purpose of the present invention is to adjust the fan blade outside deployment or storage inside, adjust the angle of the windmill fan blade according to the wind direction, and malfunction the generator due to excessive high speed operation It is to provide a wind turbine structure of a wind power generator capable of preventing damage.

In order to achieve the above object, the present invention provides the following wind turbine structure of a wind power generator.
The wind turbine structure of a wind power generator has a generator and a rotating shaft installed in the base.
A plurality of movable rotating blades of the windmill are installed on the outer periphery of the rotating shaft,
At least one support arm is connected to the inner surface of each of the plurality of blades, and the opposite ends of the plurality of support arms are fixedly connected to the outer periphery of the rotating shaft,
Between the rotating shaft and the plurality of blades, two relative connecting rods of an interlocking mechanism are installed,
The two joint rods are respectively installed on the opposite sides of the plurality of reciprocal connecting rods, whereby the two connecting rods are folded or expanded relative to each other,
The swing angle of the plurality of blades is adjusted through the spindle joint and the two connecting rods, the rotation speed of the plurality of blades and the rotation shaft is controlled, and the rotation speed of the rotation shaft is excessively increased. It is possible to avoid the failure and damage of the generator due to the high speed, the structure is simple, the maintenance is easy, and unlike other conventional brake system devices, the rotation speed can be automatically controlled using the mechanical principle. Can
A plurality of blades of the windmill are arcuate plates, and when they are stored, they gather together to have a spherical appearance.
Moreover, each of the plurality of blades is in a straight arc shape, and when stored, they gather together to form a cylindrical shape.
The plurality of blades can be moved and adjusted by operating the two connecting rods and the weight joint of the interlocking mechanism, and have a method of shifting and deploying at various angles to the outside. The blades can be folded and sealed to avoid excessive speeding up of multiple blades. The interval between operation (motion) and stop (static) is short, no restart is required, and power generation efficiency is high. .

The wind turbine structure of the wind power generator of the present invention uses a plurality of blades of a wind turbine, and an interlocking mechanism is installed between the inner surface and the rotating shaft. When the weight joint is movably connected between the rods and multiple blades receive the wind and move, the rotation of the rotating shaft is interlocked, and each blade of the interlocking mechanism is swung to the outside according to the swing of each blade. Or it can be folded inward to control the speed at which each blade rotates in response to wind, thereby slowing down the rotation of each blade and rotating shaft, preventing generator failure or damage due to excessive high speed rotation be able to.
Moreover, the linkage mechanism between the blades has a connecting rod in the same direction on both sides of the weight joint, and the two connecting rods extend smoothly, expand or fold, and gather together, so there is no brake In this case, the operation can be started quickly and the power generation efficiency can be increased.
Multiple linkage rods and spindle joints with two interlocking mechanisms swing smoothly corresponding to each blade, the structure and equipment are simple, maintenance and inspection are easy, the service life of generator and windmill Can be extended.

It is a local side view of the present invention. It is a side view which shows the state which the braid | blade of this invention developed. It is a side view which shows the accommodation state of this invention braid | blade. It is a three-dimensional external view of an embodiment of the present invention. It is a local side view of the fan of the conventional wind power generator.

  As shown in FIGS. 1, 2, 3, and 4 which are three-dimensional external views, a bird's-eye view, a bird's-eye view showing a use state, and a local side view of the present invention, the wind power generator of the present invention includes a base 1, a windmill 2, The interlocking mechanism 3 is provided.

  A generator 11 (detailed structure not shown) is installed on the base 1. Moreover, the rotating shaft 12 is installed by extending outward from the generator 11. The rotating shaft 12 is used to drive the operation of the generator 11, generate electric power, store it in a power storage device such as a storage battery or a rechargeable battery, or transmit it to various electronic and electrical products that require electric power.

  The windmill 2 includes a plurality of blades 21, and at least one connection base 22 is installed on the inner side surface 211 of each blade 21. Each connection base 22 connects support arms 23 in a movable manner, so that the plurality of blades 21 perform movable swings on one side of each support arm 23.

  The interlocking mechanism 3 installs a weight joint 32 between two opposing rods among the plurality of connecting rods 31. As a result, the plurality of connecting rods 31 that are opposed to each other are folded relative to each other or can be expanded outward. Guard bodies 33 are installed on the outer sides of one of the connecting rods 31 so that each connecting rod 31 is pushed to the opposite side and can be prevented from being bent.

  When assembling the above-described constituent members, the rotating shaft 12 extending out of the generator 11 of the base 1 is used. The outside of the rotating shaft 12 is surrounded by a plurality of blades 21 of the windmill, and at least one support arm 23 is installed on the inner surface 211 of the plurality of blades 21. The opposite end of each support arm 23 of each blade 21 is fixedly installed on the outer surface of the rotating shaft 12. Further, between the rotary shaft 12 and the inner surfaces 211 of the plurality of blades 21, two of the interlocking mechanisms 3 are connected to the side surfaces of the inner surfaces 211 of the blades 21 by a plurality of relative connecting rods 31. The fixed end is fixed and installed, and the opposite end is fixed and installed on the outer surface of the rotating shaft 12. Two interlocking rods 31 of each interlocking mechanism 3 interlock each blade 21 around each support arm 23. Thus, a movable swing, opening and closing are exhibited outside the rotating shaft 12, and the wind turbine structure of the inventive wind power generator is configured. The wind turbine structure of the inventive wind power generator has a simple overall structure and is easy to maintain and inspect.

  The plurality of blades 21 of the windmill 2 described above present an arc-shaped plate. Thus, the plurality of blades 21 can be folded in a timely manner on the outer periphery of the rotating shaft 12 of the base 1 to form a spherical sealed type. At this time, the plurality of blades 21 are tightly coupled on the outer periphery of the rotary shaft 12 and are not blown by the wind force.

  In addition, the interlocking mechanism 3 uses a plurality of weight joints 32 and both sides move in the same direction to connect the connecting rods 31. As a result, the two connecting rods 31 are movable and stored relative to each other, or are expanded outwardly, so that clogging or catching is less likely to occur, and no movable resistance force is generated. Thus, the two connecting rods 31 are smoothly extended, unfolded, or folded and stored in accordance with the swing of each blade 21. The structure between the interlocking mechanism 3 and the plurality of blades 21 is simple, maintenance is easy, and failure can be quickly eliminated.

  When using a wind power generator, the base 1 is used to localize to a predetermined position (such as a rooftop, a highland, an open area, or a coast where the airflow is large). Then, the weight joint 32 of the interlocking mechanism 3 hangs down by receiving the gravity of the earth, and the two of them pull the relative-type connecting rods 31 and fold them to the inner sides facing each other. One side of the inner surface 211 of the plurality of blades 21 is pulled. As a result, the plurality of blades 21 rotate and swing around the support arms 23, respectively, and expand radially on the outer periphery of the rotation shaft 12. Thus, a space is formed between the plurality of blades 21, and the wind force blows to the inner side surfaces 211 of the plurality of blades 21 in the direction of the wind. As a result, the plurality of blades 21 are driven, the synchronous rotation of the rotary shaft 12 is interlocked by the support arms 23, and the generator 11 is interlocked by the rotary shaft 12 to generate power. In the present invention, the time required for operation (rotation) and stop (rest) of the plurality of blades 21 is short and can be activated quickly.

  In addition, unlike the other conventional brake system devices, the present invention automatically controls the rotational speed using the mechanical principle.

  As shown in FIGS. 1, 3, 4, 5, and 6 which are three-dimensional external views of the present invention, an overhead view of a use state, a local side view, a side view of blade deployment, and a side view of blade storage. When the generator 11 of the base 1 is operated, the windmill 2 installed on the outer periphery of the rotating shaft 12 is used. The plurality of blades 21 are blown and rotated by the wind force, interlocking with the rotation of the rotating shaft 12, and interlocking with the operation of the generator 11 to perform power generation work.

  If the wind is strong and the rotational speed of the rotating shaft 12 that the windmill 2 surrounds increases, the centrifugal force generated by the plurality of blades 21 extends by pulling the connecting rod 31 on one side of the interlocking mechanism 3 to which it is connected, The connecting rod 31 to which each blade 21 is connected is interlocked, and the weight joint 32 is pulled and moved upward synchronously. The connecting rod 31 located on the opposite side of the weight joint 32 moves upward and extends in accordance with the weight joint 32. In this way, the connecting rod 31 can be prevented from bending in the opposite direction. At the position where the connecting rod 31 is connected to each blade 21, two relative connecting rods 31 and the weight joint 32 are further moved by using the guard body 33 positioned outside each connecting rod 31. Is received and pushed to the opposite side to prevent bending, and the plurality of blades 21 shift outward with the support arm 23 as an axis. As a result, the plurality of blades 21 surround the outer side of the rotating shaft 12, wrap around the outer periphery of the rotating shaft 12, and have an appearance like a sealed sphere. Thus, by sealing and storing the plurality of blades 21 in a timely manner, they are not blown by the wind. At the same time, the rotation shaft 12 stops operating, decelerates, and enters a buffered state, and it is possible to avoid an excessive increase in the rotation speed due to the plurality of blades 21 being blown by strong wind. Thereby, rotation of the rotating shaft 12 at an excessively high speed can be prevented, and damage or failure of the generator 11 can be avoided. In this way, the plurality of blades 21 of the windmill 2 are each subjected to the control of each interlocking mechanism 3, and a situation in which the rotational speed is not excessively high during rotation does not occur. The life can be effectively extended. On the other hand, the stationary time of the plurality of blades 21 and the rotary shaft 12 is very short, the two weight joints 32 wait for two to pull the relative connecting rod 31 and bend, the plurality of blades 21 immediately start rotating, The rotation of the rotating shaft 12 can be interlocked.

  When the plurality of blades 21 of the windmill 2 wrap around the outer periphery of the rotating shaft 12, the rotation is stopped, but the stationary interval time is short and the brake is not applied, so the power generation efficiency is high. The weight joints 32 connected to the intermediate positions of the connecting rods 31 between which the two interlocking mechanisms 3 face each other between the plurality of blades 21 and the rotary shaft 12 are affected by the gravitational force of the earth. Moreover, the connecting rods 31 on both sides are pulled inward, folded, and assembled. Therefore, the two relative connecting rods 31 do not catch each other, and no clogging or resistance force is generated between the two relative connecting rods 31 and the weight joint 32. The connecting rod 31 on one side of each interlocking mechanism 3 pulls one side of each blade 21 synchronously, whereby the plurality of blades 21 rotate about each support arm 23 as an axis. As a result, the plurality of blades 21 are deployed radially outside the rotating shaft 12, and each connecting rod 31 is not pushed in the opposite direction due to the obstruction of the guard body 33. In this way, the plurality of blades 21 of the wind turbine 2 develop outward at an appropriate angle, and the inner side surfaces 211 of the plurality of blades 21 become surfaces that receive wind again. The inner side surfaces 211 of the plurality of blades 21 blown by the external wind force move the plurality of blades 21 and interlock the rotation shaft 12 to recover the rotation. Moreover, the rotating shaft 12 can generate power in conjunction with the generator 11 to achieve a state where there is no braking action. It is not necessary to restart all of the plurality of blades 21, the rotary shaft 12, and the generator 11, and since the operation and stop are performed in a short time, the interval time is short, and thus the power generation efficiency can be increased.

  As shown in FIGS. 1 and 7 which are a three-dimensional external view of the present invention and a three-dimensional external view of one embodiment, the plurality of blades 21 of the windmill 2 installed outside the rotating shaft 12 of the base 1 of the present invention have an arc shape. The outer side of the rotating shaft 12 is wrapped. Since the spherical shape has a good spoiler action, it is easily blown by the wind and easily rotates smoothly. In addition, the plurality of blades 21 also have an arcuate surface and wrap around the rotating shaft 12 and thus have a cylindrical shape.

The above is only an example of the present invention, and does not limit the scope of utility model registration of the present invention. The wind turbine structure of the wind turbine generator of the present invention uses the rotating shaft 12 on the base 1 and installs a plurality of blades 21 of the wind turbine 2 outside. Moreover, the two connecting rods 31 of the interlocking mechanism are connected between the inner surface 211 of the plurality of blades 21 and the rotary shaft 12. In addition, a weight joint 32 and a guard body 33 are movably connected between the two connecting rods 31. As a result, when the plurality of blades 21 are radially deployed on the outer periphery of the rotary shaft 12, the blades 21 are blown and rotated, and the rotary shaft 12 is interlocked to drive the generator 11 to generate power.
In addition, when the plurality of blades 21 of the windmill 2 rotate too fast and are excessive, the two connecting rods 31 of the interlocking mechanism 3 are attracted by the centrifugal force of the blades 21 to synchronize the weight joint 32. It is linked to and stretched linearly. Further, the position is limited and stopped by the guard body 33, and the plurality of blades 21 wrap around the outer periphery of the rotating shaft 12, stop the rotation, and achieve the purpose of decelerating the rotation of the rotating shaft 12. Moreover, since it can start immediately after stationary and the brake is not applied, the interval time of movement and static is short, and the several blade 21 and the rotating shaft 12 can be started rapidly, and electric power generation efficiency is improved. be able to. Furthermore, since the rotating shaft 12 rotates too fast, the generator 11 can be prevented from operating inappropriately and causing failure or damage. That is, it has functions of deceleration, buffering, and generator 11 protection. When the windmill 2 rotates, the interlocking mechanism 3 is used to form a tension, and an excessive increase in the rotation speed of the blades 21 of the windmill 2 can be avoided.

As described above, the wind turbine structure of the inventive wind power generator has the following advantages during actual use.
1. The outer periphery of the rotating shaft 12 of the base 1 is surrounded by a plurality of blades 21 of the windmill 2, and the interlocking mechanism 3 is installed between the inner surface 211 of the plurality of blades 21 and the rotating shaft 12. Are coupled with each other according to the centrifugal force of rotation of the plurality of blades 21, whereby the plurality of connecting rods 31 and the weight joint 32 opposed to each other are straight. The plurality of blades 21 surround and wrap around the outer periphery of the rotary shaft 12, are in a sealed state, are not blown by the wind, achieve the purpose of deceleration, and can be started immediately after being stationary. Since it can be stopped and restarted quickly without the brake applied, power generation efficiency can be increased.
2. The interlocking mechanism 3 is provided with connecting rods 31 on both sides by the weight joint 32, and the two connecting rods 31 move in the same direction on both sides of the weight joint 32 and are expanded, folded and stored. Therefore, it is difficult for a catching state to occur, swings smoothly according to each blade 21, the structure is simple, and maintenance and inspection are easy.
3. The technical concept of the present invention, unlike other conventional brake system devices, automatically controls the rotational speed using the mechanical principle.
