Description

  The present invention relates to a wind tunnel rotary blade installed in a wind tunnel and used for power generation.

  The inventor of the present application, in Patent Document 1 described later, has a wind receiving surface on the tip end side that can easily receive the wind, and an opening that allows the wind to pass under a specific condition on the side close to the axis (close to the axis). We have devised a wind tunnel rotor blade which is provided with (vent holes or vent slits) to make it easier to receive the wind on the other wind receiving surface on the downwind side and to make it easier to rotate.

  After that, we proposed the patent documents 2 and 3 mentioned below, and tried for improvement of these.

Patent No. 5240883 Patent No. 5768234 Patent No. 5877458

  However, although these patented inventions are more effective than before, they can not stay at rotational speeds up to 350 revolutions per minute and can not obtain practical rotational speeds of 500 revolutions per minute or more. There has been a demand for practical use of wind tunnel rotary vanes capable of obtaining such high rotational speed and high torque rotational force. Among them, electric vehicles, for which extension of the cruising distance is desired in recent years, are expected to be improved in the configuration that can generate and charge while running.

  The present invention has been made in view of the problems as described above, and it is possible to increase the rotation to a higher rotation range on the premise of the invention configuration of Patent Document 1, and obtain high torque torque. It is intended to provide a wind tunnel rotary blade.

  As apparent from the above-mentioned Patent Documents 2 and 3, the inventor has devised a wind receiving surface provided on the blades of the rotary vanes in an attempt to increase the rotational speed of the wind tunnel rotary vanes. And even after that, the experiment has been repeated many times with the improvement of the wind receiving surface, but although new findings are obtained, the number of rotations within the range of 350 rotations / minute is absolutely limited, and more, for example, It can not generate power when used in cars and trains, and can not provide a practical power generation capacity that can be used for these traveling and other purposes, and so far, devices have been devised for the wind receiving surface I felt the limit in my idea.

  Therefore, the present inventor attempted to fundamentally change the idea, deviated from the idea from devising the above-mentioned wind receiving surface, and decided to consider a new configuration from the ground as a whole structure.

  The new idea aimed at increasing the total amount of wind blowing through the wind tunnel and increasing its pressure. That is, by increasing the pressure of the wind blowing through the wind tunnel, the number of rotations of the rotating blades is increased to the practical range.

  Therefore, the inventor considered how the wind can be pushed into the wind tunnel on the windy side of the wind tunnel. Here too, it was not possible to reach the purpose just by the configuration based on the basic idea.

From the above history, the present inventor has made the present invention having the following configuration as an invention. That is, the configuration according to the present invention is
When installed in a wind tunnel, the blade which is blown out of the wind tunnel is rotated by one or a plurality of blades projecting into the wind tunnel and rotates while the wind which blows the wind tunnel is received by the blade and the rotating blade rotates It is a wind tunnel rotary blade that causes a generator to generate power using a force, and the rotary blade is formed as a wind receiving surface shaped into a shape that easily receives the wind at a position away from its axis. When the part closer to the axis than the wind receiving surface has moved to a position orthogonal to the wind that blows the wind tunnel, the wind blows from the part near the axis, and the wind that blows through the wind tunnel A wind tunnel rotary wing in which a ventilating hole or ventilating slit is formed at a position closer to the axis of the front blade so that it can be received by the wind receiving surface of another blade on the further leeward side. In,
The wind tunnel is divided into at least two stages of the wind tunnel of the rotary blade installation position portion and the wind tunnel of the upper stage with respect to the wind escape direction,
It is composed of a plurality of vertical blades on at least one side of the entry side near the entry side opening of each step, and also has a wind receiving surface molded into a shape that easily catches the wind, and viewed from the wind tunnel opening The wind tunnels are respectively provided with wind pushing and rotating bodies so that the respective wind receiving surfaces of the wind tunnel can receive and rotate the wind on the central portion side of the wind tunnel and the rotation can push the wind toward the wind tunnel side. The basic feature is that the axes of the wind-pushing and rotating bodies arranged at the same position are connected to be coaxial.

  In the original configuration, a wind push-in rotating body consisting of vertical blades is simply provided on both sides of the wind tunnel opening, and the wind is blown through the wind tunnel, but with such a configuration alone, the wind tunnel is It turns out that some rotating blades themselves become resistance, and the pushed-in air can not escape efficiently to the rear.

  Therefore, in consideration of a configuration for further improving the wind blow-through, the wind tunnel is formed in a plurality of stages in the vertical direction, and the above-mentioned rotary vanes are placed at the lowermost level, and the upper wind tunnel is basically configured to blow the wind.

  The wind tunnel on the upper side only blows through, and there is no other resistance in particular, so naturally the amount of wind blowing through there will be large. There is no way not to use the force of the wind flowing through the upper wind tunnel. Therefore, not only at the lowermost stage, but also at the opening on both sides of the upper stage, wind push-in rotating bodies composed of vertical blades are simultaneously provided, and the wind blowing through the upper wind tunnel is forced to blow through those wind tunnels. Is connected to the shaft of the wind push-in rotary body located at the lowermost stage, so that the above-mentioned wind tunnel rotary vane is present, so that the resistance is increased. The wind volume of the lowermost stage is falling, and by connecting the axes of the wind-inward pivoting members from the upper stage to the lowermost stage, the force of the increased wind volume of the upper-stage wind tunnel can be maximized. By transmitting it to the shaft of the wind-pushing rotary body at the lower stage, the rotational force of the wind-pushing rotary body is further increased, thereby pushing the wind blowing through the lower wind tunnel with a stronger force and sending it to the wind tunnel rotary vanes. , Of the wind tunnel rotary blade Rolling speed, and it becomes possible to increase the rotation torque. According to the results, the number of revolutions of the wind tunnel rotor was well over 550 revolutions / min.

  According to the present invention having the above configuration, the wind is used to freely blow the wind tunnel on the upper stage side having almost no resistance, and the force is transmitted to the wind pushing rotary body at the lower stage, and the wind pushing turn at the lower stage. Since the wind tunnel rotating blades are rotated by increasing the force to push the wind of the moving body, it generates power when used in cars and trains, etc. A practical power generation that can use the electricity for these traveling and other purposes It became possible to gain power. Here, the wind blowing through the upper-stage wind tunnel is hardly resisted during passage, and the wind passing through the lower end finally strongly turns the wind-pushing rotating body on the lower side.

  With regard to the above-described wind pushing and rotating body, it is preferable that the diameter of the wind pushing and rotating body provided on both sides of the upper wind tunnel be larger than the diameter of the wind pushing and rotating body provided on the lowermost wind tunnel. This is because in the upper stage wind tunnel where there is little wind resistance to the wind tunnel, the wind blows through with great speed, and at that time, the wind pushing rotary body on the entry side also turns well because it can push a large amount of wind into the wind tunnel. It will be. The force acts as a rotational propulsive force of the lowermost wind-pushing rotating body, and turns it at the lowermost stage. Therefore, if the diameter of the wind pushing rotary body provided in the upper wind tunnel is made larger than the diameter of the wind pushing rotary body provided in the lower wind tunnel, the rotation of the lower wind pushing rotary body becomes high. This is because the force of pushing the wind into the wind tunnel of the wind pushing and rotating body is significantly higher than when the wind tunnel is not provided in the upper stage.

  In the case of an actual configuration in which the wind tunnel is two-tiered, in such a configuration, the upper end slightly protrudes from the plate partitioning the upper and lower wind tunnels when one of the wind tunnel rotary blades comes to the top. If the setting position of the wind tunnel rotary blade to the rear of the partition plate is set as described above, more preferable results will be obtained. This is not only due to the above effect, but also because the wind pushing rotary body at the lower stage is high in rotation and the force to push the wind into the wind tunnel of the wind pushing rotary body at the lower stage is high. If the setting of the rear part of the partition plate is performed so that the upper end thereof protrudes when one of the wind tunnel rotary blades comes to the top, the upper end of the wind tunnel rotary blade is an upper wind tunnel having almost no resistance. It is pushed by the wind that blows through and increases the rotational force more.

  On the other hand, in the wind tunnel rotary blade having such a configuration, the upper end of the wind tunnel outlet side downstream portion is squeezed while being smoothly inclined behind the rotary blade in the lowermost wind tunnel outlet side downstream portion where the rotary blades are installed. If the air flow of the wind tunnel is combined, the result will be better. The merging of the air flowing through the wind tunnel at the rear is mixed and trying to flow, but the air density of the lowermost wind tunnel is low, and it is connected to it, and the lower air is more , Because it is easy to be pulled backward. In the structure combined with the structure which one upper end of a wind-tunnel rotary blade protrudes from the board which divides an upper-lower wind tunnel, it became a result which can obtain rotation speed exceeding 650 rotations / min.

  The above configuration is capable of achieving the number of revolutions of 550 winds or more of the wind tunnel rotary blade, but since the wind which has flowed into these wind tunnels escapes to the rear, several stages of similar constructions behind it It is also possible to provide and generate electric power by a plurality of the above-mentioned wind tunnel rotary blade composition and to use. That is, in the above-described wind tunnel rotor blades, when the plurality of units are continuously provided with these integrated configurations behind the first wind tunnel rotor blade down the wind tunnel, power generation amount is increased by the number. Will be able to

  According to the configuration of the first wind tunnel rotary blade of the present invention, the wind is used to freely blow the upper-stage wind tunnel having almost no resistance, and the force is transmitted to the lowest stage wind-pushing rotating body, Since the wind tunnel rotating blades are rotated by increasing the wind force of the wind pushing rotary body at the lower stage, the power generation capacity is enhanced, and it is possible to obtain an excellent effect that it is possible to obtain a practical power generation power. I will get it.

  According to the second configuration of the present invention, in the upper stage side wind tunnel having little wind resistance to the wind tunnel, the wind blows through with great momentum, and at that time, the wind pushing rotary body on the entry side also has a large amount of wind Will be turned well, and the force will be the rotational propulsive force of the lowermost wind-pushing rotating body, and it will turn it at the lowermost stage, so the wind provided in the upper-stage wind tunnel If the diameter of the pushing rotary body is made larger than the diameter of the wind pushing rotary body provided in the lowermost wind tunnel, the rotation of the lower wind pushing rotary body becomes high, and the wind is introduced into the wind tunnel of the lower wind pushing rotary body. It is possible to obtain an effect that the pushing force is much higher than when the upper stage has no wind tunnel.

  According to the third configuration of the present invention, the setting position of the wind tunnel rotary blade and the setting of the rear portion of the partition plate are performed such that the upper end thereof protrudes when one of the wind tunnel rotary blades comes to the top. Then, the upper end of the wind tunnel rotor blade is pushed by the wind blowing through the upper wind tunnel having almost no resistance, and the rotational force is further increased, so that the number of rotations of the wind tunnel rotor blade can be increased.

  According to the fourth configuration of the present invention, the upper end of the wind tunnel outlet side downstream portion is squeezed while being smoothly inclined behind the rotary vanes at the lower end wind tunnel outlet side downstream portion where the rotary vanes are installed. The air flow of the wind tunnel is merged, and the air merging in the wind tunnel at the rear is mixed and trying to flow, but at that time the air density of the lowermost wind tunnel becomes low, and it is Finally, the lower stage air flow is increased more and more, and the wind tunnel rotor blade rotation efficiency is increased because the lower stage air is more likely to be pulled backward to compensate for the lack of density. It will be. By combining this configuration with the third configuration, it is possible to obtain a rotational speed exceeding 650 rpm.

  According to the fifth configuration of the present invention, the configuration of the integrally formed wind tunnel rotary blade is continuously provided in the back of the wind tunnel of the first wind tunnel rotary blade and the power generation is performed respectively. The amount of power generation can be increased by that number.

Hereinafter, embodiments of the present invention will be described together with illustrated examples.
As shown in FIGS. 6-9, when the wind tunnel rotary blade of Patent Document 1 is installed in the wind tunnel 2a, the wind blowing through the wind tunnel 2a is generated by the blade 10 that protrudes one or more to the wind tunnel 2a. The rotary blade 100 receives and rotates, and the blade 10 is formed into a shape in which the axially offset portion 10b is extended outward from the rotation axis of the rotary vane 100 and the wind is easily received in the extension direction of the axially offset portion 10b. A wind tunnel is provided which is provided with the received wind receiving surface 10a, receives wind blowing through the wind tunnel 2a on the wind receiving surface 10a of the blade 10, and generates electric power using a rotational blade of the rotating blades rotated by that force. In the blade 100, when the rotary blade 100 is rotationally moved to a position orthogonal to the wind blowing through the wind tunnel 2a, the portion 10b closer to the axis than the wind receiving surface 10a A part of the front blade 10 so that the wind blows from the part 10b near the axis of the blade and the wind that blows through is received by the wind receiving surface 10a of another blade 10 on the leeward side of the wind tunnel 2a. The ventilation hole or the ventilation slit 1 is bored only at the position 10b.

  With such a configuration, a portion (root side) 10b closer to the axis than the wind receiving surface 10a of a certain blade 10 of the rotating blade 100 rotating in response to the wind in the wind tunnel 2a is against the wind blowing through the wind tunnel 2a. When rotational movement has been made to the orthogonal position, as shown in FIG. 8, the wind which blows through the inside of the wind tunnel 2a passes through the ventilating hole or ventilating slit 1 to another blade on the windward side of the wind tunnel 2a. It will come into contact with the 10 wind receiving surfaces 10a. The wind receiving surface 10a of the other blade 10 receives the strongest wind and then gradually weakens, and at the same time it receives the wind that has newly passed through the ventilation hole or the ventilation slit 1, further Because a strong rotational force is given, even if it is placed at that position, the rotational force will be stronger. At this time, since the wind receiving surface 10a of the blade 10 having the ventilation holes or the ventilation slits 1 through which such wind blows through will soon receive the wind blowing directly in the wind tunnel 2a, at least two blade winds are received. On the surface 10a, the wind tunnel rotary blade 100 receives the wind blowing through the wind tunnel 2a, whereby a stronger rotational force can be obtained. After that moment, at the position where the other blade 10 mentioned above is slightly rotated from there, the wind which has fallen downward as shown in FIG. 9 changes its direction and blows to the leeward side of the wind tunnel 2a. , It will join with the wind which blows through the inside of the wind tunnel 2a as it is. This is the configuration of the invention of Patent Document 1 that enables power generation and the like to be performed using the wind blowing through the inside of the wind tunnel without generating an overflow.

  FIGS. 1 and 2 are explanatory views showing the first and second embodiments of the configuration of the present invention in which the performance is further improved by using the configuration of Patent Document 1 as it is. As shown in the figure, in the configuration of this embodiment, the wind tunnel is divided into two stages of the wind tunnel 2a at the installation position portion of the rotary vane 100 and the wind tunnel 2b at the upper stage thereof in the wind escape direction.

  Further, it comprises a plurality of vertical blades on at least one side of the wind tunnels 2a and 2b, each having at least one wind receiving surface similarly shaped to easily receive the wind, on both sides of the entrance side opening vicinity of the wind tunnels 2a and 2b. When viewed from the side, the wind receiving rotary bodies 3a and 3b and 30a and 30a and so that the respective wind receiving surfaces on both sides receive the wind at the wind tunnel central portion side and can rotate the wind by the rotation. Axes 30b are respectively provided, and the axes of wind-injecting rotating bodies (3a and 30a, 3b and 30b) arranged at the same position of the wind tunnels 2a and 2b divided into upper and lower parts respectively are connected and coaxial (31a and 31b) There is.

  Because of the above configuration, the wind tunnel 2b on the upper side only blows the wind and does not receive any other resistance, so the amount of wind blowing there is naturally larger than that of the lower wind tunnel 2a. Become. It is an embodiment configuration of the present application to try to use the force of the wind flowing through the upper wind tunnel 2b. Therefore, not only the wind tunnel 2a of the upper stage but also the wind pushing rotary bodies 30a and 30b configured by the longitudinal blades are simultaneously provided on the upper side of the wind tunnel 2a and the wind tunnel 2b of the upper side. The wind-blowing rotary bodies 30a and 30b, which rotate well in the upper-stage wind tunnel 2b while increasing the amount by which the wind tunnel 2b is blown by the wind-blowing rotary winder 2a By connecting to the axis of 3 and 3b (31a and 31b), the wind tunnel rotary blade 100 up to this point has become a resistance, and the wind volume of the lower stage has fallen, the wind pushing rotary body from the upper stage to the lower stage By connecting the shafts (3a and 3b and 30a and 30b) and turning (31a and 31b), the force by the blowing amount of the increased wind of the upper-stage wind tunnel 2b can be obtained by rotating the lower wind-pushing pivot 3a. By further transmitting the torque to the shaft of the wind tunnel 3a and 3b, the rotational force of the wind pushing rotary bodies 3a and 3b is further increased, and the wind blowing through the wind tunnel 2a in the lower stage is pushed in with a stronger force and sent to the wind tunnel rotary vane 100. It has become possible to increase the rotational speed and rotational torque of the wind tunnel rotary blade 100. From the experimental results, it was found that the number of revolutions of the wind tunnel rotary vane 100 was well over 550 revolutions / minute while rotating the generator (wind tunnel rotary vane 100: generator = 1: 1).

  Further, in the configuration of the present embodiment, as shown in FIGS. 1 and 2, the diameters of the wind pushing rotary bodies 30a and 30b provided on both sides of the upper wind tunnel 2b are the wind pushing rotary bodies 3a and 3b provided on both sides of the lower wind tunnel 2a. It is larger than the diameter of 3b. This is because in the upper stage wind tunnel 2b where there is little wind resistance to the wind tunnel, the wind blows with great speed, and at that time, the wind-inward pivoting members 30a and 30b also enter a large amount of wind into the wind tunnel 2b. It will turn well because it can be pushed. The force is the rotational propulsive force of the wind pushing rotary bodies 3a and 3b of the lower wind tunnel 2a, and it turns the lower one (the wind pushing rotary bodies 3a and 3b). Therefore, if the diameters of the wind pushing pivoting members 30a and 30b provided in the upper wind tunnel 2b are made larger than the diameters of the wind pushing rotary members 3a and 3b provided in the lower wind tunnel 2a, the wind pushing rotary members 3a and 3b The rotation becomes high, and the force of pushing the wind into the wind tunnel 2a of the wind pushing rotary bodies 3a and 3b in the lower stage is significantly higher than that when the wind tunnel 2b is not present in the upper stage.

  According to the first and second embodiment configurations according to the present invention having the above-described configuration, the wind is blown freely through the wind tunnel 2b on the upper side having almost no resistance, and the force thereof can be When the wind tunnel rotary vane 100 is rotated by transmitting to the pushing rotary bodies 3a and 3b and increasing the force of pushing the wind of the wind pushing rotary bodies 3a and 3b in the lower stage, the wind tunnel rotary vane 100 is used in cars and trains etc. It has become possible to generate electricity and to use that electricity for these and other purposes to obtain a practical generation capacity. Here, the wind blowing through the wind tunnel 2b on the upper side hardly receives any resistance during passing, and the wind passing through the wind will finally turn strongly the wind pushing rotary bodies 3a and 3b on the lower side. .

  FIGS. 3 and 4 show the configuration of the wind tunnel rotary blade 100 according to the third and fourth embodiments having the configuration of the present invention. As shown in these drawings, when one of the wind tunnel rotating blades 100 comes to the top when the wind tunnel is in the upper and lower two stages, it is slightly smaller than the partition plate 20 that divides the upper and lower wind tunnels. The setting position of the wind tunnel rotary blade 100 or the setting of the rear portion of the partition plate 20 is such that the upper end (the upper end of 10a) protrudes (the extension line of the partition plate 20 is shown as a dotted line 20a in FIG. 3) If done, it will lead to more favorable results. This is because the rotation of the wind pushing rotary members 3a and 3b in the lower stage increases and the force of pushing the wind into the wind tunnel 2a of the wind pushing rotary members 3a and 3b in the lower stage increases. Rather, the installation position of the wind tunnel rotor blade 100 or the setting of the rear portion of the partition plate 20 is such that the upper end thereof projects (projects above the dotted line) when one of the wind tunnel rotor blades comes to the top. If this is the case, the upper end of the wind tunnel rotary blade 100 is pushed by the wind which blows through the upper wind tunnel 2b with almost no resistance, thereby further increasing the rotational force. Moreover, as will be described later, in the present embodiment, the pressure in the wind tunnel 2b is increased by the configuration of the throttle 20b, and the tip of the wind tunnel rotary blade 100 is pushed to absorb much stronger rotational force. This will be described later.

  This configuration has an original concept of the configuration of Patent Document 1 and a concept similar to Columbus' egg-like in a sense. That is, in Patent Document 1 having the premise configuration, when a portion (root side) 10b closer to the axis than the air receiving surface 10a of a certain blade 10 is rotated to a position orthogonal to the wind blowing through the wind tunnel 2a. As shown in FIG. 8, the wind blowing through the wind tunnel 2a passes through the ventilation holes or the ventilation slits 1 and strikes the wind receiving surface 10a of another blade 10 on the more leeward side of the wind tunnel 2a. . In response to the wind coming through the ventilation holes or the ventilation slit 1, a stronger rotational force is given, so that the rotational force will be intensified even if placed at that position. At this time, since the wind receiving surface 10a of the blade 10 having the ventilation holes or the ventilation slits 1 through which such wind blows through will soon receive the wind blowing directly in the wind tunnel 2a, at least two blade winds are received. On the surface 10a, the wind tunnel rotary blade 100 receives the wind blowing through the wind tunnel 2a, whereby a stronger rotational force can be obtained.

  On the other hand, in the configuration of the present embodiment, only the effect of the first embodiment is that the rotation of the wind-pushing pivoting members 3a and 3b at the lower stage becomes high and the force to push the wind into the wind tunnel 2a by it becomes high. If the setting position of the wind tunnel rotary blade 100 or the rear portion of the partition plate 20 is set so that the upper end (the upper end of 10a) protrudes when one of the wind tunnel rotary blades 100 comes to the top, The upper end of the wind tunnel rotor blade is pushed by the wind which blows through the upper wind tunnel having almost no resistance, and the rotational force is further increased, and another force is biased by the rotational position of the wind tunnel rotor blade 100 This is because a force to turn the wind tunnel rotary blade 100 acts.

  Furthermore, in the present embodiment, the lower end portion of the upper wind tunnel 2b on the outlet side is squeezed while being smoothly inclined behind the rotary vane 100 at the lower outlet portion of the lower wind tunnel 2a where the wind tunnel rotary vane 100 is installed. And the air flows of the wind tunnels 2a and 2b are merged. By the configuration of the throttle 20b, the pressure in the wind tunnel 2b is increased. Moreover, the merging of the air flowing through the wind tunnels 2a and 2b at the rear is mixed and trying to flow, but the air density of the lower wind tunnel 2a becomes low, and it is added to it to compensate for the density shortage. The air in the wind tunnel 2a is more likely to be pulled backward. These factors will further increase the rotational force of the wind tunnel rotor 100.

  Not only that, in the present embodiment, the lower end portion of the wind tunnel 2a on the outlet side is opposed to the throttle 20b on the outlet side downstream portion of the upper portion of the wind tunnel 2b, and the throttle 20c is configured. With the configuration of applying the throttles 20b and 20c from the upper and lower sides of the wind tunnel, the flow velocity of the wind penetrating through there is faster by the throttled portion, and the air flow behind the wind tunnel is joined to make the flow of the wind tunnel 2a Not only pulling out but also the flow of the wind at the merging portion becomes faster, so the air in the lower stage is more likely to be pulled backward, resulting in a rotational speed exceeding 650 rotations / minute.

  According to the configurations of the first embodiment and the second embodiment, the wind tunnel rotary vane 100 alone can achieve the number of rotations of 550 rotations / minute to 650 rotations / minute or more. When the wind speed is measured at 70 km / h at the entrance side of the wind tunnels 2a and 2b in the above configuration, the wind speed at the exit side is 63 km / h, and about 90% of the speed is downwind of these wind tunnels. I'm going out to the side. Therefore, in the present embodiment, as shown in FIG. 5, a plurality of similar configurations (Xa to Xd) are provided behind the same to generate power using a plurality of the above-described wind tunnel rotary vane configurations. That is, in the above-mentioned wind tunnel rotary blade, a plurality of units (Xa to Xd) are continuously provided such that these integral configurations (X) are provided downstream of the first wind tunnel rotary blade down the wind tunnel (Xa to Xd) to generate power respectively. Therefore, although the amount of power generation decreases toward the rear, the amount of power generation can be increased according to the number.

  The wind tunnel rotor blade of the present invention is not limited to the above-described embodiment, and it goes without saying that various modifications can be made without departing from the scope of the present invention.

  The wind tunnel rotor blade according to the present invention may be used for power generation equipment, for example, electric vehicles and plug-in hybrid vehicles, and other trains and ships other than cars, as long as they can generate power using wind. It goes without saying that it is also possible.
