Description

[0001]
BACKGROUND OF THE INVENTION
  The present invention relates to a blade of a rotating wheel and a rotating wheel, and more particularly to a blade disposed around a rotating body of a windmill, and a tailwind hitting the inner and outer surfaces of the blade is used as an efficient rotational thrust to enter the rotating body. The present invention relates to a rotating wheel and its blades configured to increase the negative thrust generated on the inside of the blades by discharging the wind at a high speed outward, thereby increasing the rotational thrust of the blades.
[0002]
[Prior art]
  Conventionally, a wind turbine of a wind power generator uses a horizontal axis propeller type, and a vertical axis wind turbine having a wind power recovery rate of about 35% is not used because it is not practical.
  Further, since the blades of the vertical wind turbine in the past are set so as to obtain lift toward the outside of the blades, there is a difficulty that it is difficult to obtain thrust in the rotational direction.
  In addition, since centrifugal force is applied to the top and bottom of the blade as the rotating body rotates, the lift is applied to the blade and the centrifugal force overlaps, so the blade is easily damaged and prevents damage. For this reason, if the rigidity of the blades is given, the weight becomes heavy and the rotational efficiency is deteriorated.
[0003]
  In particular, the vertical axis wind turbine has blades on the periphery of the rotating body, and the direction of the blades is reversed with rotation, so the effect of the wind on the blades is unpredictable. Theories have been established, but no academic theory on wind effects on rotating blades has been studied.
  In this regard, the inventor has developed a wind turbine that generates a rotational thrust by using the negative pressure generated in the wind receiving blades and rotates faster than the wind speed, and is disclosed in Patent Documents 1 and 2, for example.

[Problems to be solved by the invention]
  Although the wind receiving blades of the above-mentioned literature have a high wind recovery effect, the blades disposed on the periphery of the rotating body are physically faster on the outer surface than the inner surface due to the difference in diameter ratio when rotating. It is rotating at.
  Therefore, when the blade rotates, the speed of the wind that passes separately on the inner and outer surfaces of the blade at the front of the blade is physically higher than the speed of the wind that passes along the outer surface of the blade.
[0005]
  When the bulging part that creates rotational thrust is formed on the inner surface of the blade, the speed of the wind passing along the inner surface of the blade during rotation increases, negative pressure is generated in the front edge region of the blade, and the blade A normal pressure airflow acts on the negative pressure portion of the inner side surface region from the outer side surface region, and a rotational thrust is generated in which the blades are pushed in the rotation direction.
[0006]
  However, when the rotational speed of the rotating body increases, the rotational speed of the blades increases, so the wind that enters the rotating body surrounded by the blades follows the rotational direction of the rotating blades and moves outward. The airflow that is difficult to come out and stagnates as a vortex on the inside makes it difficult for the wind passing at high speed along the inner surface of the blade to escape to the outside, thereby reducing the rotational thrust.
[0007]
  The present invention allows the wind passing along the inner surface of the blade during rotation to pass outward at a higher speed even during high-speed rotation, and as a result, the blade of the rotating wheel that provides strong rotational thrust, and rotation The purpose is to provide a car.

DETAILED DESCRIPTION OF THE INVENTION
  Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a front view of a rotating wheel blade (hereinafter simply referred to as a blade) according to the present invention.So, this front is rotated forward. 2 is a cross-sectional plan view taken along line AA in FIG. 1, and FIG. 3 is a left side view of the blade.In use, it is the inside surface. 4 is a cross-sectional view taken along the line BB in FIG.The left side of the figure is the inner side and the right side is the outer side.
[0018]
  Figure1The blade (1) is composed of a main body (2) and a mounting support (3) formed on the left side (inner side) of the longitudinal center.
  The main part (2)In FIG.The vertical center isThicknessIs thick, and it extends to the top and bottom tips.Thickness isIt is set to become thinner gradually. 4 is a cross-sectional plan view taken along the line BB in FIG. In this way the feather (1)CrossingThe width of the surface shape is gradually reduced as it reaches the upper and lower ends of the blade (1).
[0019]
  The plane shape of the wing (1) is approximately fish-shaped as shown in FIG.The front is thick and the rear edgeGradually to the departmentThinlyThe middle core line (S) connecting the front end portion and the rear end portion is formed so as to be along the rotation track (T) of the blade (1) when disposed on the rotating body (5) shown in FIG. Is curved.
[0020]
  As shown in FIG. 2, the core wire (S)AcrossThe left and right sides of the main part (2) are different in thickness. The bulging part (2b) on the right side (outer side) of the core wire (S) is thinner than the left side (inner side), and the bulging part (2b) is formed on the inner side. ing. In addition, a concave portion (2c) that is recessed inward from a straight line connecting the bulging portion (2b) and the rear end portion is formed in the outer surface at the rear portion.
[0021]
  On the left side (inner side) of the main part (2)Width (wing chord length)As shown in FIG. 3, gradually from the vertical center to the upper and lower ends.NarrowlyIt is formed to become. The mounting support (3) shown in FIGS. 2 and 3 is arranged on the radiation passing through the center of the rotating body (5) shown in FIG.
[0022]
  Since the position of the mounting support (3) is at the front edge of the blade (1), the rear end is more inward than the front end of the blade (1).(Left side)The mounting support (3) is disposed in a state inclined to the front. This is on the rightsurfaceAs shown in FIG. 1, the bulging portion (2a on the right side) is located on the inner side of the rotating track (T1) of the bulging portion (2a) on the outer side. ) Is the wind at the frontHitSince the area is small, the resistance during rotation is small.
[0023]
  AndAs shown in FIG.The left side surface (inner side surface) of the blade (1) main body (2) extends from the bulge (2b) that creates the rotational thrust.leftThe surface is inclined outward from the rotating track (T2) of the bulging portion (2b).
  Therefore, when the blade (1) rotates, the inner surface of the main part (2)(The left side)The wind that passes rearward and outward is faster than the speed of the wind passing through the outer surface of the main body (2), and negative pressure is generated in the inner front edge area of the blade (1), and the blade (1 ) Is generated.
[0024]
  The high-speed wind that passes obliquely outward through the inner surface of the main body portion (2) escapes outward from the inner rear portion of the main body portion (2) inclined outward. In this case, the rear part of the main body part (2) is an upper and lower part, and the length from the front is short, so it passes quickly in a short time.
[0025]
  The wind passing through the outer surface of the main part (2) is changed in atmospheric pressure in the recessed part (2c), so the high-speed wind that exits rearward outward from the inside (left side) of the blade is outside the blade (1). Involves the wind that tries to pass through and pushes the blade (1) later.
[0026]
  In this way, during rotation, the wind passing along the inner surface of the blade (1) quickly escapes obliquely outward, so that it does not affect the subsequent rotated blade (1) that passes thereafter. Also, if the wind blows and the wind hits the inner surface of the blade (1), the wind will also go out diagonally after the blade (1),RotateThe wind is less likely to stay inside the rotating body (5) surrounded by the blades (1).
[0027]
  The shape of this blade (1) isPlate thicknessIs formed thin, it is difficult to receive wind resistance during rotation. Front and rear width of feather (1)(Wing chord length)WidenWhen rotatingSince the core wire (S) is along the rotating track (T), it is difficult to receive wind resistance. In addition, the rear part of the inner surface of the blade (1) is inclined outward, and the wind passing along the inner surface is quickly removed to the rear and outside, so the influence of the passing wind on the blade that follows in the rear position Not give.
[0028]
  From this, it is possible to ensure a sufficient wind receiving area without increasing the longitudinal length of the blade (1). In particular, since the blade (1) rotates together with the rotating body, it always reverses every half rotation.endPart becomes wind resistance burden.
[0029]
  Therefore, normal blades are(Wing chord length)However, this blade (1) has a horizontal width at the top and bottom ends that is larger than the front and rear width at the vertical center.NarrowlyAs a result, the load of wind pressure resistance at the time of turning is reduced.(Wing chord length)It was possible to widen the wind receiving area.
[0030]
  Furthermore, the thickness of the central part of the main part (2) is thick and the front-rear width(Wing chord length)Since it is long, it has excellent rigidity and strength. Therefore, the rotational efficiency can be increased by using the rotating body (5) having a larger diameter as shown in FIG. 8 without changing the size of the blade. In addition, on the side surface of the blade (1), the upper and lower end portions of the main body portion (2) can be set to be inclined in the front-rear direction.
[0031]
  5 is a front view showing a second embodiment of the blade, FIG. 6 is a cross-sectional plan view taken along line AA in FIG. 5, FIG. 7 is a left side view of the blade, and FIG. 8 is a plan view of a rotating vehicle equipped with the blade. is there. The same parts as those in the previous example are denoted by the same reference numerals and description thereof is omitted.
[0032]
  In FIG. 5, the upper and lower end portions of the blade (1) of the blade (1) are gradually curved from the longitudinal center portion toward the left side (inner side). The right curved surface of the rotating body (5) on which the blade (1) is disposed,OutsideIt can be set according to the curved surface close to the circumferential curved surface.
[0033]
  As shown in FIG. 7, the left side surface of the blade (1) is vertically long, the height of the main body (2) is, for example, 2.6 m, and the center front and rear length is 50 cm.Side shape isThe rear part is formed in a triangular shape in the shape of a back point. This size is suitable when the diameter of the rotating body (5) described later is 4 m, but is not limited to this.
[0034]
  In FIG. 8, the rotating body (5) of the rotating wheel (4) is vertically supported by the support body (6).VerticalThe main shaft (7) is mounted at a right angle. The rotating body (5) is an annular body via a plurality of support arms (9) on the shaft portion (8).
(10) is fixed. A plurality of blades (1) are provided at predetermined intervals around the periphery of the ring body (10), and the inner surface of the blade (1) is arranged vertically in the direction of the main shaft (7). The ring body (10) can be positioned easily even when the number of blades (1) changes, in addition to stabilizing the rotation by the rotational inertia. Further, it is possible to project an arm (not shown) from the annular body (10) in the radial direction and attach the blade (1) to the tip of the arm, that is, the rotation radius of the blade (1). Can be greatly changed.
[0035]
  In the rotating wheel (4) configured as a windmill having the above-described configuration, when the blade (1) receives the wind indicated by the arrow A, the rotating body (5) rotates in the direction indicated by the arrow B.
  At this time, the core (S) of the blade (1) main body (2) rotates along the rotating track (T). In addition, the wind indicated by the arrow C that hits the front of the blade (1) with rotation is the same as the rotation speed of the blade (1), but branches and flows to the left and right of the blade (1).
[0036]
  That is, in FIG. 6, the outer bulging portion (2a) is a part of the mounting support (3) in FIG. 5, and therefore is about half the vertical length of the blade (1) in the vertical direction and shown in FIG. Therefore, the outer bulge portion (2a) during rotation is small in wind resistance.
[0037]
  Next, the bulging portion (2b) on the inner side surface (left side) in FIG. 6 that forms the rotational thrust is the position of the portion of the mounting support (3) in FIG. 7, but as shown in FIG. ThenBulge (2b) IsBecause it occupies more than half of the height,Bulge (2b) InWind resistance is greater than the outer surface. This is because the wind subjected to resistance passes to the rear part at a high speed, so that a negative pressure is created by the bulging part (2b) that creates the rotational thrust, and a normal pressure outside the blade (1) is generated. Since the atmospheric pressure pushes the blade (1) to the inner front, a rotational thrust is obtained.
[0038]
  In addition, as can be clearly seen in FIG. 6, the wind that passes through the inner surface (left side surface) of the blade (1) at a high speed to the rear portion of the blade (1) Since it is inclined outward, it goes out outward from the rotating track (T) of the blade (1). This is a force that winds the wind passing through the outer rear part outward and pushes the blade (1) forward.
[0039]
  Since the upper and lower edges of the blade (1) are almost the same as the cross section shown in FIG. 6, the atmospheric pressure from the outside as indicated by the arrow D inwardly intersects with the inclination of the upper and lower edges in FIG. Take it. Further, the atmospheric pressure in the direction indicated by the arrow E is applied inward and perpendicular to the outer rear surface of the blade (1) in FIG. This acts as a rotational thrust of the blade (1).
[0040]
  In FIG. 8, when the wind in the direction of arrow A is blowing, each blade (1) rotates in the direction of arrow B. With this rotation, the wind approaching the rotating body (5) is dragged in the direction of rotation of the blade (1). The front blade (1A) in FIG. 8 receives the head wind from the right side in FIGS. 5 and 6 and slides on the inclined surfaces of the upper and lower parts of the main body (2) to the upper and lower surfaces.
[0041]
  That is because in FIG. 5, the speed of the wind that passes through the point PR is faster than the speed of the wind that passes through the point QR, so that the rear outer surface of the blade (1) in FIG. The area becomes negative pressure, and at the rear side of the inner surface of the blade (1), a force is applied to press the normal pressure from the inside to the outside. As a result, even if the blade (1A) in FIG.
[0042]
  The blade (1B) on the left front side in FIG. 8 receives a tailwind on the outer surface to obtain a rotational thrust. In this case, the outer surface of the upper and lower edges of the blade (1B) is curved inward.
Press the back of (1B). Further, the wind that goes around the inner surface of the blade (1B) is accelerated in speed by the bulging portion (2b), and a negative pressure is generated in the inner front edge region of the blade (1B) to obtain a rotational thrust.
[0043]
  The blade (1C) on the left leeward side in FIG. 8 receives the tail wind indicated by the arrow A on the inner surface, and obtains rotational thrust. In a state where a tailwind is received from the left in FIG. 5, the wind hitting the upper and lower inclined surfaces of the main part (2) gathers to the center, pushes the blade (1C), hits the bulging part (2a), and moves forward. When the wind passing through is further accelerated and the wind speed is faster than the rotational speed, a strong negative pressure is generated in the inner front edge area of the blade (1C) to generate a rotational thrust.
[0044]
  When the wind in the direction of arrow A hits the blade (1D) under the right wind, the wind that hits the upper and lower inclined parts of the main body (2) flows backward while pushing the blade (1D), The wind flows rearward and outward from the blade (1D) and pushes the blade (1D) forward.
  When the right front blade (1E) receives the wind indicated by the arrow A, a negative pressure is generated on the left side surface of the blade (1E), and rotational thrust is also obtained.
[0045]
  Thus, the rotational thrust is obtained for the blades (1A) to (1E) facing in any direction. And the wind entering the rotating body (5) surrounded by the blades (1A) to (1E) is reduced by the high speed rotation and the passage distance between the front and rear blades is reduced. It is discharged from the top and bottom.
[0046]
  FIG. 9 is a front view of a blade showing the third embodiment, and FIG. 10 is a cross-sectional plan view taken along line AA in FIG. The same parts as those in the previous example are denoted by the same reference numerals and description thereof is omitted. This embodiment is characterized in that the upper and lower edges of the main body (2) are curved outward.
[0047]
  In this embodiment, the difference from the second embodiment is that the direction of the upper and lower ends of the main body (2) is opposite, but the rotating body (5) rotates as can be seen in FIG. Depending on the position, the direction in which the tip of the blade is curved changes, so that the action of the blade (1) receiving the wind is similar.
  In addition, since it is curved, it has a three-dimensional shape, is excellent in rigidity against stress from any direction, and is not easily damaged even if a centrifugal force is applied during high-speed rotation.
[0048]
  However, in FIGS. 9 and 10, when the wind indicated by the arrow A blows from the left, the wind hitting the upper and lower edges of the main body (2) passes quickly along the curved surface.
  That is, in FIG. 9, the speed of the wind that slides between the points P and R is faster than the wind that goes straight between the points P and Q.
[0049]
  Therefore, the leeward blades (1A) and (1D) in FIG. 8 are slow to pass through the wind indicated by the arrow A, but at the same position, the blade (1) in FIG. It can be quickly passed outward.
[0050]
  In FIG. 10, the wind indicated by the arrow C is less likely to receive large resistance at the upper and lower edge portions of the main body (2) when it escapes rearward and obliquely along the inner surface of the blade. That is, the wind that has entered the inside of the rotating body (5) surrounded by the blades (1) can be discharged to the outside more quickly.
[0051]
  This means that the high-speed wind passing along the inner surface of the rotating blade (1) can pass faster, and the faster the high-speed wind, the faster the front surface of the inner surface of the blade (1). This is because a negative pressure is generated and the rotational thrust of the blade (1) is increased.
[0052]
  FIG. 11 is a front view of a blade showing the fourth embodiment, and FIG. 12 is a cross-sectional plan view taken along line AA in FIG. The same parts as those in the previous example are denoted by the same reference numerals and description thereof is omitted.
  In this embodiment, at the front, the upper and lower end edge portions are each bent at the middle portion to the right side and the upper and lower end portions are bent to the left side.
  This is a combination of the good points of Examples 2 and 3, and in addition to this, since it has a three-dimensional structure with no straight portion, it has excellent rigidity and strength.
[0053]
  FIG. 13 is a front view of a blade showing the fifth embodiment. The same parts as those in the previous example are denoted by the same reference numerals and description thereof is omitted. In this embodiment, at the front, the top and bottom tips of the main body (2) of the blade (1) are curved to the right from the longitudinal center, and the top and bottom tips are curved to the left. In this case, the curved portion is opposite to that of FIG. 11, but when rotating, the direction is reversed, so the effect appears in the same way.
[0054]
  FIG. 14 is a plan view of the rotating wheel. This rotating wheel (4) is substantially the same as that shown in FIG. 8, but is characterized by the blade (1) disposed on the rotating body (5). That is, on the front surface of the blade (1), the upper and lower ends of the main body (2) have a blade (1F) curved in the left direction and a blade (1G) curved in the right direction of the rotating body (5). It is characterized by being alternately arranged on the periphery.
[0055]
  In FIG. 14, there are three leftward-facing curved blades and three rightward-facing curved blades. However, when these are four to four, oppositely facing blades can be disposed on the opposing surface.
  When the blades (1F) (1G) having different curvature directions are alternately arranged in this way, the rotating body (5) rotates, so that the wind pressure change due to the blades (1F) (1G) during rotation is It is less likely to affect the blades that follow and rotate.
[0056]
  In addition to being used for wind turbines for wind power generation, the blades of the present invention can be used for blades of water turbines. For example, by applying water pressure from the direction indicated by the arrow A to the blades of the rotating wheel (4) in FIG. 8, the rotating wheel (4) can be stably rotated.
  Further, the main shaft (7) of the rotating wheel (4) is made horizontal, and the blades are submerged in the water channel. The water flow can be rotated by pushing the blades, and the blades can escape from the water.
[0057]
【The invention's effect】
  As described above, the present invention has the following excellent effects.
[0058]
  (1) In the blade of the invention described in claim 1, the transverse plane in the longitudinal center of the blade main body is substantially fish-shaped, and the core wire connecting the tip and the rear end is attached to the rotating body and rotated. Since the blades are curved along the rotating track, there is an effect that the wind resistance is small during rotation even if the front and rear widths of the blades are long. As a result, there is an effect that the wind receiving area can be widened without increasing the longitudinal length of the blades.
  Also, the side shape of the main part is the top and bottom tip part with respect to the vertical center part.Side width gradually narrowsSince it is formed, the burden of wind resistance is small at the turning point when the direction reverses with rotation, so that the cause of the stall is eliminated.
[0059]
  (2) In the blade according to the second aspect of the present invention, the bulging portion that creates the rotational thrust of the inner surface is set largely at the front end edge portion, rather than the bulging portion outside the central core line in the transverse plane. Therefore, the speed of the wind passing along the inner surface is faster than the speed of the wind passing along the outer surface of the blade during the rotation of the blade, and the air density at the inner front edge of the blade is dilute and negative pressure is reduced. As a result, the blade has an effect of obtaining a self-propelled rotational thrust.
  Moreover, since the rear inner side surface extending from the inner bulge portion to the rear end portion is inclined rearward and outward, the high-speed wind passing along the inner side surface of the blade escapes diagonally outward from the blade, The blades come out of the rotating track of the blades, and this has the effect that the high-speed wind does not affect the blades that follow and rotate at the rear position.
  In addition, the high-speed wind that exits diagonally outward pushes the wind that passes along the outer surface of the blades outward, so the atmospheric pressure wind on the outside pushes the blades from the outside rear, and self-propelled rotational thrust It is a plus.
  Furthermore, when the blades rotate at high speed, the wind that enters the rotating body surrounded by the blades is dragged in the direction of rotation of the blades to generate a vortex. If this vortex is left as it is, the wind flow passing along the inner surface of the blades stagnates in the rotating body, and as a result, the rotational thrust is reduced. Since the rear part is inclined obliquely rearward and rearward, these airflows are promptly discharged out of the rotating track of the blades, so that the vortex is not generated.
  The blades are set to be thin from the center to the top and bottom, and the cross-sectional shape of the blades in the vertical center is approximately the same shape, and gradually scales to correspond to the width and length from the upper and lower ends of the main part. Therefore, in the front, wind resistance during rotation is small, but the above effect can be obtained in the same manner above and below the blades. Moreover, since the vertical center part of a blade | wing is thick, there exists an effect excellent in rigidity strength.
[0060]
  (3) Since the blade of the invention described in claim 3 is formed with a recessed portion recessed inward from the straight line connecting the outer bulging portion and the rear end portion at the rear portion of the outer surface of the main body portion. The wind that passes along the outer surface from the front surface of the blade causes a pressure change phenomenon in the recessed portion, and pushes the blade from the rear side in combination with the wind that passes through the inner surface of the blade and exits rearward and outward. effective.
[0061]
  (4) In the blade according to the invention described in claim 4, the main body portion is curved inward from the central portion to the upper and lower end portions, so that it resists against the head wind received on the outer surface of the blade. In addition, when the wind is applied to the inner surface of the blade, wind force is obtained by holding the wind, and the wind is quickly discharged backward. Moreover, it becomes a three-dimensional shape by bending, and is excellent in rigidity against stress from either, and has an effect that it is difficult to be damaged by high-speed wind and centrifugal force during high-speed rotation.
[0062]
  (5) In the blade according to the invention described in claim 5, since the main body portion is curved outward from the central portion to the upper and lower ends, the rotating body surrounded by the blade during high-speed rotation There is an effect that the wind that has entered inside can be efficiently discharged to the outside by the curved surface of the inner surface of the main body. Moreover, it becomes a three-dimensional shape due to the entire curvature, and is excellent in rigidity against stress from either, and has an effect of being difficult to break against high-speed wind and centrifugal force during high-speed rotation.
[0063]
  (6) In the blade according to the invention described in claim 6, since the main body portion has upper and lower end edge portions bent to the right side and front end portions thereof are bent to the left side in the front surface. Although the upper and lower end portions are curved to the left or right, there is an effect that each has good points. Moreover, it becomes a three-dimensional shape by bending to the left and right, has excellent rigidity strength against stress from either, and has the effect of being difficult to break against high-speed wind and centrifugal force during high-speed rotation.
[0064]
  (7) In the blade according to the invention described in claim 7, since the main body portion has the upper and lower end edge portions bent in the left direction on the front surface, and each tip portion thereof is bent in the right side. Although the upper and lower end portions are curved to the left or right, there is an effect that each has a good point. Moreover, it becomes a three-dimensional shape by bending to the left and right, has excellent rigidity strength against stress from either, and has the effect of being difficult to break against high-speed wind and centrifugal force during high-speed rotation.
[0065]
  (8) In the rotary wheel described in claim 8, the blades disposed on the periphery of the rotating body are alternately arranged with blades whose upper and lower tips are curved leftward and blades curved rightward. Therefore, the balance of wind reception is good, and there is an effect that the change of the airflow by the blades does not affect the blades rotating following the rear position during rotation.
