Abstract

<P>PROBLEM TO BE SOLVED: To improve the efficiency of power generation by generating power even in the case of a lower wind speed lower than the movable starting speed of two meters in wind power generation, and to improve the efficiency of the power generation by continuously operating without stopping even in the case of a strong wind at which operation has conventionally been stopped. <P>SOLUTION: Operation can be performed even in the case of a low wind speed by collecting winds from an area larger than a blade area of a turbine, and power generation is enabled even in the case of a strong wind by using a vertical axial flow type wind power generating device. A wind power generation system is constituted by including a turbine 3 with a rotating stand capable of rotating by itself to receive the wind where the only vane at a side receiving the wind in a central part between the nearly circular top plate 1 and a bottom plate 2 opposite to each other in apexes of venturi-type streamlines thereof protrudes to a ventilation area. A motor 11 under the turbine 3 is fixed and rotated by a gear mechanism. A wind directing plate 4 is provided at an appropriate position over the center to the outer edge of the top plate 1 and the bottom plate 2. In this case, a part of the wind directing plate 4 brought into contact with the top plate 1 and the bottom plate 2 is formed into a streamline, but it is unnecessary to form a flat surface into a streamline. The turbine 3 includes a direction blade 5 in a rod fixed to the center of the turbine 3 and protruding to pass through the top plate 1, and the direction blade is rotated dependently in the direction of wind to direct the direction of the turbine 3 in a direction corresponding to the wind. The direction blade 5 can be installed in the other place, and can be installed in a stand for rotating the turbine 3. <P>COPYRIGHT: (C)2011,JPO&INPIT

Patent Publication 6-137258

Problems to be solved by the invention

    Venturi-type wind collectors increase the inflow and outflow of wind and widen the wind speed range of wind power generators.

Means for solving the problem

For efficient wind inflow and outflow, a Venturi type wind tunnel device, which is considered to have a low pressure loss, is used, and a wind turbine for power generation is installed in the center where the wind force is compressed. As a result, the movable wind speed range can be achieved even with low speed wind. Also, it collects a lot of wind and discharges a lot.
While providing a convex part in the center of a wind collector, a wind power generator installs installation. The inflow / outflow part of the wind is an opening larger than the convex part. The wind is compressed from the inflow portion of the wind to the convex portion, and the outflow portion is diffused from the convex portion, thereby increasing the amount of inflow and outflow of the wind and increasing the power generation efficiency.
A wind direction plate is appropriately installed inside the air collecting device, and the size of the device is easily increased by allowing the wind from all directions to flow in and out without the operation of the air collecting device itself.
The tip portions of the two conical discs face each other up and down, and a wind collecting plate is provided between them to support them while they are joined.

  In the wind power generation system shown in FIG. 1, only the rotor blade on the side receiving wind at the center between the substantially circular top plate 1 and the bottom plate 2 facing the top of the venturi-type streamline goes out to the ventilation region. There is a turbine 3 with a turntable that can rotate and receive wind. The motor 11 portion below the turbine 3 is fixed and rotated by a gear mechanism. A wind direction plate 4 is appropriately installed from the center to the outer edges of the top plate 1 and the bottom plate 2. In this case, the wind direction plate 4 is a streamlined portion in contact with the top plate 1 and the bottom plate 2, but the plane may not be streamlined. The turbine 3 is fixed to the center of the turbine 3 and has a directional blade 5 on a rod protruding so as to penetrate the top plate 1. The turbine 3 rotates in accordance with the wind direction so that the turbine 3 is directed in a direction corresponding to the wind. The directional blades 5 can be installed at other locations, and may be installed on a table that rotates the turbine 3.

  As shown in FIG. 2, when wind flows from one direction, the turbine 3 generates electricity by passing through the turbine 3 at the center and exiting in the opposite direction. Outside the blades of the turbine 3, there is a rectifying plate 13 and a gear box 12 covering the gears 7 and 8 of FIG. And the direction wing | blade 14 is installed in the center part.

  As shown in FIGS. 2 and 3, the space surrounded by the wind direction plate 4 and the top plate 1 and the bottom plate 2 becomes narrower toward the center of the turbine 3 and becomes larger as it goes outward from the center. Pass through. As a result, the turbine 3 is moved to generate power.

  The gantry 6 shown in FIGS. 1 and 3 may be installed under the bottom plate 2 by utilizing the passage of wind under the bottom plate 2, in which case the directional blade 5 is easy to operate. As described above, the gantry 6 can be installed radially from the vicinity of the center portion of the bottom plate 2 while avoiding the movable range of the directional blade 5.

  The gear mechanism shown in FIG. 4 converts the horizontal axis of the turbine 3 into a vertical axis. When the horizontal axis of the turbine 3 fixed to the horizontal axis starts to move due to wind, the gear 7 and the gear 8 are constant as indicated by arrows. The gear 7 rotates directly in the direction, and the gear 8 directly rotates the gear 9 as indicated by the arrow, thereby moving the gear 10 through the gear 9 in a certain direction as indicated by the arrow. When the gear 10 fixed to the motor 11 moves, the motor 11 generates electricity.

  FIG. 5 is an external view of a wind power generator that moves the wind collecting device in the wind direction. The wind tunnel device 15 is cylindrical and the inside is a venturi type wind tunnel device 15 as shown in FIGS. 6, 7, 8 and 9, and the inside is streamlined and receives the wind of the horizontal or vertical axis turbine 3 at the center. The wind tunnel device 15 in which only the moving blade on the side is installed in the ventilation region and the directional blade 5 is rotatably installed on the gantry 6 according to the wind direction makes the directional blade 5 the leeward side, and the wind passing through the inside is the turbine 3 To generate electricity.

  In the wind power generation system shown in FIG. 10, only the moving blade on the side receiving the wind at the center between the substantially circular top plate 1 and the bottom plate 2 facing the tops of the venturi-type streamline faces so that the passage of the wind is good. There is a turbine 3 with a turntable that can turn itself and receive wind. The motor 11 shown in FIG. 12 below the turbine 3 is fixed and is rotated by the gear 21 and the gear 22 shown in FIG. There is a wind direction plate 4 from the central portion to the outer edges of the top plate 1 and the bottom plate 2, and they are appropriately installed so that the top plate 1, the bottom plate 2, and the wind direction plate 4 collect air efficiently on the turbine 3. In this case, the wind direction plate 4 is a streamlined portion in contact with the top plate 1 and the bottom plate 2, but the plane may not be streamlined. The turbine 3 shown in FIG. 11 has a middle wing 14 whose tip is inclined at the center, and a lateral wing 16 that receives wind on both sides, so that these receive wind and the direction of the turbine 3 receives wind from the front. The rotating table of the turbine 3 is rotated. The direction of the turbine 3 can also be adjusted by making the gear box 12 and the middle blade 14 inclined, or by making the lateral blades 16 attached to the left and right of the turbine 3 symmetrical. Directional wings can be installed in other locations and shapes.

  As shown in FIGS. 11 and 12, when wind flows from one direction, the turbine 3 rotates by passing through the turbine 3 at the center and exiting in the opposite direction. There is a rectifying plate 13 outside the turbine 3 and a gear box 12 shown in FIG. 11 that covers the gear 21 shown in FIG. 13 to rectify the wind and reinforce the blades. Then, the wind of the middle wing 14 and the lateral wing 16 changes the direction of the turntable of the turbine 3 so that the wind hits from the front of the turbine 3.

  As shown in FIGS. 11 and 12, the space surrounded by the wind direction plate 4 and the top plate 1 and the bottom plate 2 becomes narrower toward the center where the turbine 3 is located, and the Venturi type wind tunnel device becomes larger as it goes outward from the center. Pass through. At this time, when the wind strikes the middle wing 14, the lateral wing 16, and the turbine 3, the turbine 3 rotates its direction so that the wind strikes from the front, and rotates the blades of the turbine 3. Then, the horizontal axis of the turbine 3 shown in FIG. 13 starts to move, the gear 21 and the gear 22 start to rotate in a certain direction as indicated by arrows, and the motor 11 fixed to the gear 22 moves, whereby the motor 11 generates power.

  14, 15, 16, and 17 are wind power generation systems including an in-wheel motor built-in turbine 19, and a central portion between a substantially circular top plate 1 and a bottom plate 2 at which vertices of a venturi-type streamline face each other. There is an in-wheel motor built-in turbine 19 having a turntable that allows only the moving blades that receive wind to enter the ventilation region and rotate by itself to receive wind.

  The in-wheel motor built-in turbine 19 and the slip ring 17 shown in FIG. 17 are connected, and the slip ring 17 and the storage battery device 18 are always in contact with each other even if the turntable of the in-wheel motor built-in turbine 19 rotates, thereby fixing the fixed storage battery. The device 18 is charged.

  The directional blade 20 shown in FIG. 15 receives not only the wind from the front direction but also the wind from the rear receiving port and the middle wing 14 whose tip is pointed in a right triangle even when the wind direction is from the rear direction. Thus, the in-wheel motor built-in turbine 19 is rotated so that the front of the in-wheel motor built-in turbine 19 receives wind.

    As shown in FIGS. 18, 19, and 20, the space surrounded by the wind direction plate 4, the top plate 1, and the bottom plate 2 becomes narrower toward the center of the turbine 3, and becomes larger as it goes outward from the center. Wind passes through the device. A double-sided blade 24 that is a part of the turbine 3 shown in FIG. 20 is inclined forward and backward to correspond to winds from the front and rear. The lateral blade 23 shown in FIG. 19 has a wind receiving port at the front and rear, and a portion of the horizontal blade 23 whose tip is inclined to the turbine 3 is vertically provided in the middle of the front and rear receiving ports. Sometimes the wind is received and the turntable of the turbine 3 is rotated.

  19 and 20, when the wind is from the front, the wind strikes the lateral blades 23 and the turbine 3 is kept so as to receive the wind from the front. The motor 11 connected to is rotated to generate power. Since the tip of the double-sided blade 24 is inclined forward and backward with respect to the wind from behind, the turbine 3 rotates to generate electric power. When wind comes from the side, a part of the transverse blade 23 provided perpendicularly to the turbine 3 of the transverse blade 23 receives the wind to rotate the rotating table of the turbine 3 and from the front or the rear of the turbine 3. Power is generated by receiving wind.

  The movable wind area expands in both low and high wind speed areas.
