Description

[0001]
[Industrial application fields]
The present invention relates to an improvement of a wind turbine using wind power, and is characterized in that it can be increased in size and improved in use efficiency to generate power or operate a fluid pump to be used as a power source.
[0002]
[Prior art]
A windmill is a power source with a small environmental load, and it is required to promote its use as an alternative energy to fossil fuels.
[0003]
Conventional wind turbines mainly have two types, vertical axis type and horizontal axis type, and vertical axis wind turbine types include Savonius type, cup type, freight type, etc. The blades are fixed to receive wind force and rotate with the vertical axis.
[0004]
In addition to steel plates, cloth and resin are used for the blades, and a transmission mechanism is applied to the vertical shaft, which is used as a power source for generators and the like.
[0005]
In addition, there is a vertical axis wind turbine that attaches a windbreak guard to either the left or right radius centered on the vertical axis to block the wind force on the resistance surface of the rotor blade and effectively use the rotor blade on the wind receiving surface. Yes, but many vertical axis wind turbines are small and simple.
[0006]
On the other hand, the horizontal axis type mainly receives wind power from the propeller and rotates around the top of the column at right angles to the wind direction. As an environmental technology equipped with a wind power generator, a propeller with a diameter of 60 meters is popular. is doing.
[0007]
[Problems to be solved by the invention]
The vertical axis wind turbine receives wind power from a plurality of blades fixed to the center of the vertical shaft side surface and rotates in the direction where the blade surface area is large. Therefore, when the size is increased, this relationship acts, causing no advantage in terms of output and causing it not to spread.
[0008]
In addition, as a known technique, a windmill in which the windbreak guard described above is attached to the radius of the smaller blade surface area (back surface of the blade) around the vertical axis to block the radial wind force has been proposed, This is effective as a method to reduce the load that rotates in the direction opposite to the wind direction against the wind force, but it does not become an effective means of escaping the wind force received in the radius and strengthening the rotation of the vertical axis, and it is efficient Issues remain in the construction of vertical axis windmills.
[0009]
The other advantage of the vertical axis wind turbine is that it has a small wind turbine installation area and can be used to build large wind turbines. For example, the site can be narrow and high like a chimney of a thermal power plant, or a large parking area can be installed. It is to use the same type of windmill on the side of the car park, coast, etc. However, how to use the left and right blades centered on the vertical axis because of the above-mentioned rotor blade wind area (front and back of the blades) Whether it is used effectively and efficiently is an issue of technical solutions.

The wind turbine unit including the wind guide frame 5 safety hatch 20 shielding plate 21 attached to the rotary shaft 36 is coupled to the horizontal shaft 36 by closing the spring 24 with the force of the spring 24 to receive and rotate the wind power on all the rotary blades 2. The output is transmitted to the generator 28 or the oil pump installed on the surface of the wind turbine base 31 equipped with a plurality of wind turbine units.
[0015]
[Action]
The usage state of the axially rotating blade wind turbine according to the present invention is as follows.
B) The air guide frame 5 is formed in a rectangular semicircular eccentric shaft with respect to the longitudinal axis 1, and the air guide frame bearing 19 is provided in a rotatable manner near the front surface. The wind guide frame 5 is longer than the vertical axis 1 and is heavier than the rotor blade wind receiving surface 3 on one side, and is supported by attaching a wind guide frame support leg 5 ′ at the lower end, and is surrounded by the wind direction around the vertical axis 1. Is supposed to rotate
[0016]
The wind force that has entered the constriction 12 from the wind passage entrance 6 passes at an increased speed. At that time, the wind force is sucked by the wind force 10 that is the parent body of the constriction 12 through the secondary wind inlet 9 on the side surface and merged. The wind force 11 is directed toward the curve 8 at the back of the wind conduction path 7.
[0017]
Further, all the rotor blades 2 are rotated by receiving wind pressure so as to apply wind pressure to the rotor blade receiving surface 3 that passes through the deep curved tip and blows out from the discharge port 13 opposite to the wind direction. .
[0018]
B) A rudder 16 that adjusts the direction of the wind guide frame 5 corresponding to the wind direction is coupled 15 (see FIG. 3) to the side surface near the rear axis 14 of the wind guide frame 5 to balance the wind pressure applied to each of the rudder 16 Provided in curved surfaces 17 and 18 that are easily subjected to a pressing force in the direction of the airflow guide frame 5 on the opposite side, and the pressing force of both the airflow guide frame 5 and the rudder 16 are balanced, both of which are in the direction of the wind around the vertical axis 1 Responds to change.
[0019]
C) When the wind force entering the wind conduction path 7 exceeds the specified wind pressure, the spring 24 force of the safety hatch 20 is overcome and the spring rope 24 is pushed outward to release the overpressure wind force. , 26 on the front surface (windward side) of the rotor blade receiving surface 3 opposite to the wind guide frame 5 with a shielding plate bearing 27 attached to the vertical axis 1 in conjunction with the hook 44 connected to the shielding plate 21 via The shielding plate 21 is moved to block the overwind pressure.
[0020]
At the same time, the balance between the wind guide frame 5 and the rudder 16 is lost, the pushing force of the rudder 16 wins, and the wind guide frame 5 around the wind guide frame bearing 19 rotates backward, but the main body of the wind guide frame 5 is the wind guide frame. Since the bearing 19 is eccentric and has a long leeward installation, if the curved surfaces 17 and 18 at the tip of the rudder 16 are too large on the vertical axis 1, a reverse action is exerted (receives the opposite wind pressure) and the retreat does not go any further.
[0021]
At that time, the shielding plate 21 moves to the front surface of the rotor blade wind receiving surface 3 so as to avoid the damage by adjusting the overwind pressure without being directly hit by the overwind pressure. Therefore, the safety hatch 20 is weak and strong. When the opening / closing is repeated in response to the wind pressure and the specified wind pressure is restored, the safety hatch 20 is closed and the shielding plate 21 is retracted from the front surface of the rotor blade 2 to be closed.
[0022]
D) The upper end of the pedestal support shaft 30 installed and fixed on the flat base 29 is inserted into the pedestal bearing 45 at the center of the windmill pedestal 31 so as to be able to rotate 360 °, and at least four places near the outer periphery such as balls and wheels A pedestal pedestal 34 that can be slid and provided with a windmill pedestal hook 33 that lifts up and prevents falling is hung on the back surface of the outer periphery of the base 29 to ensure the stability of ancillary equipment installed on the windmill pedestal 31 in the horizontal direction. You can turn freely.
[0023]
The rudder 32 is firmly fixed to the left and right surfaces of the side closer to the lee side than the center of the windmill pedestal 31. When the wind blows here, the rudder 32 corresponds to the wind direction with the pedestal support shaft 30 as a fulcrum.
[0024]
On the other hand, the rotor blades 2 and 35 are rotatably supported on the horizontal shaft support legs 35, 35 on the top surface of the windmill base 31, and the wind guide frame 5 is fixed to other parts of the horizontal shaft support legs 35 to move together with the windmill base 31, that is, In accordance with the direction of the rudder 32, 32, the wind conduction path 7 inlet 6 is directed to the windward, and the wind force in the direction opposite to the wind direction is discharged 13 from the curved tip of the back so as to blow on the rotor blade receiving surface 3.
[0025]
For overpressure wind force, wind power adjustment is performed in the same manner as described above by interlocking of the shielding plate 21 via the transmission gears 25, 26 connecting the safety hatch 20 and the wire ropes 22, 23, and the rotor blade wind receiving surface 3; Damage to the wind guide frame 5 is avoided, so that the rotor blades 2 and the wind guide frame 5 that are integrated with the wind turbine base 31 by receiving wind power at the rudder 32, 32 can cope with various wind directions.
[0026]
E) A wind turbine pedestal rotating in a horizontal direction, which is mounted on a pedestal support shaft 30 standing on a foundation 40 with a central rotation hole of a wind turbine pedestal 31 and is rotatably fixed with nuts or pins that prevent the wind turbine from rising. 31 Rudder 32, 32 is firmly attached leeward from the pedestal support shaft 30 on the surface side, and a horizontal shaft 36 is inserted into a shaft support leg 35 standing upright so as to overlap with the wind guide installed above the horizontal shaft 36. A plurality of wind turbine units of a series of devices including the frame 5, the safety hatch 20, and the shielding plate 21 are joined in the horizontal direction, and supported by the shaft support legs 35 as needed, and the horizontal shaft 36 rotor blades are arranged side by side.
[0027]
On the other hand, the clearance between the rear surface of the windmill base 31 and the surface of the foundation 40 is set to a height that allows the vehicle to pass. The action of the running direction rudder 32, 32 is smoothed so that the wind guide frame 5 inlet 6 is directed to the windward and a combined output of the wind turbine unit is obtained.
[0028]
【Example】
In addition to improving the efficiency of wind power utilization, it is necessary to place importance on increasing the size of the installation area or the size of the rotor blade itself in order to put the rotor blade wind turbine along the axis into practical use. The output can be increased by stacking units of the rotor blade wind turbine (see FIGS. 1 and 7).
[0029]
That is, the wind turbine unit is stacked on the vertical axis 1 (see FIG. 5) joined to the vertical bearing 47 on the upper surface of the foundation 40 and held and joined to the bearing 48 (see FIG. 1) at the upper end of the support column 38. A plurality of rotor blades 2 are bent or curved steel plates are fixed in the same direction by welding or fixing metal fittings on the side surface of the vertical axis 1 through which is inserted.
[0030]
Further, in the horizontal axis 36 rotary blade wind turbine in which the vertical axis rotary blade 1 wind turbine is tilted sideways, the wind turbine units can be stacked (see FIG. 7), and a high output can be obtained. In consideration of the rotational force at the time of weak wind, all the rotor blades 2 are arranged without separating the wind receiving surface 3 and the resistance surface 4 against the wind force of the rotor blades 2 on both the vertical axis 1 rotary blade and the horizontal axis 36 rotary blade. Reinforcing the surrounding struts 38 is indispensable for countermeasures against strong winds that are used as the wind receiving surface 3.
[0031]
Next, the operation status based on the embodiment will be described.
1) FIG. 1 to FIG. 6 show an embodiment of a first example of an axially rotating blade wind turbine according to the present invention, and three wind turbine units are attached to the vertical axis 1 (see FIG. 1). The vertical bearing 48 at the center of the striking arm 49 is reinforced by joining the upper end of the vertical axis 1 in a rotatable manner, and the vertical bearings 48 and 48 in the middle of each wind turbine unit are also reinforced to withstand strong winds. Therefore, it is possible to build a vertical rotor with a vertical axis on a narrow site.
[0032]
The wind force from the direction of the front arrow rotates the wind receiving surface 3 of the rotor blade 2 and passes rearward. On the other hand, the wind guide frame 5 that rotates about the vertical axis 1 is half-circular eccentric and downwind. Since the center of gravity of the air guide frame 5 is leeward on the outside, the load applied to the air guide frame bearing 19 is increased. The top surface is slid to facilitate horizontal rotation.
[0033]
b) FIGS. 1 to 6 show a second embodiment of an axially rotating blade wind turbine according to the present invention. The wind guide frame bearing 19 is joined to the vertical axis 1 in an idle state (see FIG. 5). The frame 5 is pivotally attached to the opposite side of the rotor blade wind receiving surface 3 with the vertical axis 1 interposed therebetween, and wind pressure hitting the rudder 16 curved surfaces 17 and 18 coupled to the lee of the vertical axis 1 and the wind guide In order for the wind pressure applied to the head of the frame 5 to make the wind conduction path entrance 6 stationary on the windward with the vertical axis 1 as a fulcrum, the length of the rudder 16 to the leeward and the vertical axis 1 of the curved surfaces 17 and 18 Is adjusted and balanced by the extension 16 '(see FIG. 3) in the opposite direction.
[0034]
c) FIG. 3 and FIG. 5 show an embodiment of a third example of an axially rotating blade wind turbine according to the present invention. In the actual operation of the wind turbine in a natural climate condition, a wind guide frame considering the safety of the equipment. A safety hatch 20 is attached to the outer surface of 5 so as to open to the outside based on a hinge (see FIG. 6), and the wire rope 22 hung on the hook 51 on the inner surface is guided to the guide roller 22 ', and the small transmission gear 25 The wire ropes 23 connected to each other and connecting the large transmission gear 26 and the shielding plate hooks 44 are connected to each other and shifted. (See Figure 3)
[0035]
Further, a pulling spring 24 for moving the shielding plate 21 and the air guide frame 5 at the same time is placed on the shielding plate spring hook 52 and the spring hook 53 on the inner side wall of the air guide frame 5. 21 and the safety hatch 20 are closed, but when overpressured wind enters the wind conduction path 7, the wire rope 22 hung on the hook 51 on the inner surface is small in accordance with the size of the opening of the safety hatch 20. Then, the wire rope 22 wound in advance is pulled toward the safety hatch 20 and rotated. (See Figure 3)
[0036]
On the other hand, the wire rope 23 connected to the shielding plate hook 44 is wound around the large gear 26 to draw the shielding plate 21 and move it closer to the front surface of the rotor blade receiving surface 3 so that the shielding plate 21 can be moved depending on the magnitude of the wind pressure. The wind pressure applied to the rotor blade receiving surface 3 is adjusted. (See Figure 3)
[0037]
Accordingly, when the wind pressure returns to the set normal pressure, the extending spring 24 is restored by its own force, and the safety hatch 20 and the shielding plate 21 that are connected to each other are closed, and the wind force from the front is applied to the rotor blade wind receiving surface 3. The wind force that is received and enters the wind conduction path 7 receives the wind force and rotates around the rotor blade receiving surface 3 that is reversed from the opposite side.
[0038]
d) FIGS. 7 to 10 show a fourth embodiment of an axis-rotating blade wind turbine according to the invention, in which a base 29 with projections 50 laterally around the sides of a flat surface of a circle is firmly mounted on the base. The pedestal support shaft 30 is vertically fixed at the center as the base of the windmill, and the windmill pedestal 31 is mounted on the upper portion so as to be rotatable in the horizontal direction, and is fixed by a pin or nut for preventing the windmill. (See Figure 9)
[0039]
A windmill pedestal 31 supported by the pedestal support shaft 30 and capable of rotating to the left and right is provided with a pedestal support leg 34 on the back surface and supported by a roller or wheel that slides on the surface of the base 29, and a cross wire 4 connecting the centers. The tip of the pedestal hanger 33 enters the notch around the base 29 downward from the edge of the base, and rotates with the windmill base 31 so that it tilts on the protrusion 50 of the base 29. Further, the pedestal support The rudder 32, 32 is fixed to both sides of the leeward from the shaft 30, and the windmill base 31 is rotated by following the wind direction.
[0040]
The rotor blade 2 is fixed to the shaft support legs 35, 35 firmly fixed to the surface of the wind turbine base 31 through the horizontal shaft 36 of the wind turbine, and the rotor blade wind receiving surface 3 is disposed below the horizontal shaft 36. The air guide frame 5 is fixed to the shaft support leg 35 in the upward direction from the other horizontal shaft 36 so as to eliminate rainwater pools and reduce the influence of snow on the rotor blades 2. The implementation status of is the same as the first and third, and the explanation is omitted.
[0041]
The horizontal axis 36 rotor blade wind turbines are stacked as one unit and operated in the enclosure of the support column 38 (see FIG. 8), and the output is combined into one generator with the chain 39 as a transmission means. The fluid pump is driven to obtain a high output, and the use of the output transmission means has a choice of belts, shafts, gears, etc. depending on the climate environment of the installation site.
[0042]
e) FIGS. 11 to 12 show a fifth embodiment of the axially-rotating blade wind turbine according to the present invention. A wind turbine pedestal 31 assembled into a rectangular steel structure is supported by a pedestal support shaft 30 in a rotatable manner. The wind turbine unit of the horizontal shaft rotary blade 36 inserted through the shaft support leg 35 standing on the upper side surface of the base 31 is connected in the horizontal direction to increase the rotational force of the same shaft 36.
[0043]
A pedestal pedestal 34 is attached to the outside of the lower surface of the windmill pedestal 31, and a wheel pedestal 34 is installed on the pedestal support shaft 30 installation surface of the foundation 40 on the upper surface by using wheels 41. The wheel 41 on the track corresponds to the wind direction according to the rudder 32, 32 standing on the side surface of the windmill base 31.
[0044]
The lower surface of the windmill base 31 and the space on the surface of the foundation 40 can be used for parking lots, warehouses, etc., and can effectively use the site, and the height of the gate gantry 42 can be adjusted without making the surface of the foundation 40 flat. Thus, the installation location of the horizontal axis 36 rotor blade wind turbine will be wide.
[0045]
FIGS. 13 to 14 are reference examples and show a known technique of a horizontal axis fixed installation type. However, as a difference from the fourth to fifth examples, it is installed in advance assuming the wind direction and is not equipped with a rudder. However, the location is selected according to the local ventilation such as seasonal winds and continental winds. However, if the function of the air guide frame 5, the safety hatch 20, and the shielding plate 21 of the present invention is provided, the enlargement is a reality. It becomes.
[0046]
That is, since the wind guide frame 5 is fixed to the shaft support leg 35 of the horizontal shaft 36 rotor blade or the shaft post (in the case of fixed installation) instead of it, no matter how much the wind turbine unit is connected in the horizontal direction, there is no limit. If one horizontal shaft 36 is connected using a flexible joint and supported by a shaft support leg 35 or a support as necessary, it is possible to cope with changes in the terrain. . It should be noted that the mechanical safety hatch and the shield plate can be connected using an electric signal and a motor electromagnetic machine instead of a wire rope, but are omitted for the sake of clarity. As an alternative, it is possible to control the direction of the wind turbine connecting the direction sensor and the electric signal with a motor, but this is omitted for the sake of clarity.
[0047]
【The invention's effect】
As is apparent from the above, the wind-inflow process of the wind conduction path by providing a hollow wind guide frame on the resistance surface on the opposite side of the exposed wind receiving surface of the axially rotating blade according to the present invention. In addition, a positive wind force is introduced, and the rotating blades are blown against the reversing blades from the discharge port that is reversed along the curved surface, and the so-called venturi effect is exhibited.
[0048]
In other words, since the conventional vertical axis wind turbine was rotated in the direction of the rotor blade having a large wind receiving area, the reverse blade side on the back surface was rotated against the same wind force, so there was only a slight rotational force. No matter how large it was, it was only the same relationship.
[0049]
On the other hand, wind power is guided to the wind conduction path by the rudder that always directs the wind guide frame to the windward, and for excessive wind power, the safety hatch is opened and released, and the front surface of the rotor blade is closed with a shielding plate. If the outer diameter is increased as a feature of the rotor along the axis, the output increases as it is, and the present invention has already improved the resistance of the rotor. Since the load on the surface is gone, an unprecedented output can be achieved and the generator or fluid pump transmitted to the shaft is in operation.
[0050]
In addition, shaft support legs and rudder are installed on the left and right of the wind turbine base that rotates in the horizontal direction, the horizontal support blades are inserted into the shaft support legs, and the wind guide frame is installed and fixed above the shaft. In other words, the rotor blades rotate in the vertical direction with respect to the horizontal rotating shaft, and the standing rudder follows the wind direction with the wind turbine base, so the wind turbine units are stacked up to power the rotating shaft. In summary, it is possible to obtain a high output on a narrow floor.
[0051]
In addition, it is possible to provide space that uses the space between the lower part of the windmill pedestal that connects and rotates the windmill unit side by side and the surface of the foundation for various purposes. For example, a facility using the space is used as a parking lot. When the pedestal support leg track is installed on the upper surface of the gate pedestal that is high enough for humans and vehicles to pass, the space around the pedestal support shaft rotates around the space around the windmill, such as a parking lot. Facilities that generate revenue other than output can be used.
[0052]
Furthermore, in the case of a horizontal axis, a large rotary blade is realized by mounting the wind guide frame of the present invention and a safety hatch or a shielding plate on the well-known technology of the horizontal axis fixed installation type of the axis-side rotary blade. By providing a shaft support leg in the middle, there is no limit to the expansion of the rotating blades, and the wind turbine unit is continuously attached to one shaft so that the output of the rotating shaft can be taken out effectively.
[0053]
In addition, the horizontal axis fixed installation type waits for the wind according to the wind direction from a certain direction such as at sea, mountaintop, riverbed, desert, roadside, factory, etc.In the present invention, by connecting a universal joint in the middle of the rotating shaft, The utility value is even higher if it is set to several stages on a scale that is easy to maintain and manage without being installed in a straight line or flat, and effective use of renewable natural energy is realized.
