Description

  The present invention relates to a wind turbine generator using a vertical axis type windmill, and in particular, by disposing a cylindrical body having a plurality of blade members around the windmill, the forward rotation of the windmill is prevented regardless of the wind direction. The wind turbine can always rotate forward in one direction by blocking only the wind that normally rotates the wind turbine by blocking the wind with the wing member, and even with weak wind that does not rotate with a horizontal axis type wind turbine. The wind turbine starts and rotates to generate power, and the power generation efficiency is high, and since the wind turbine is not exposed, safety is high, installation space is small, noise is low, and it is fully compatible with strong winds such as storms. It relates to a wind power generator that is possible, extremely practical and high performance.

  As a typical windmill used in a wind turbine generator, there is a propeller-shaped horizontal axis type windmill 1 that rotates around a horizontal axis 2 as shown in FIGS. 18 and 19. Some large windmills have a blade diameter exceeding 60 m, but the small windmill 1 has a blade diameter of about 1 m, for example.

  The small windmill 1 is rotatably attached to the upper end of the pole 3 and is rotated in the direction of the arrow A or the arrow B so that the propeller 5 always faces the front in the direction of the wind 4 by the tail 6. ing. As a result, the propeller 5 rotates in the direction of arrow C while receiving a wind whose wind direction changes every moment, and a generator (not shown) connected to the propeller generates power.

However, in the propeller-shaped windmill 1, the wind noise of the propeller 5 may be noisy, and as shown in FIG. 19, the entire windmill 1 rotates within a range of 360 ° depending on the wind direction. The rotation range 8 and the rotation range 9 of the tail 6 need to be secured safely. Therefore, a considerably wide installation place is required, and the installation place of the wind turbine 1 needs to be selected carefully.
In order for this type of windmill 1 to start and rotate even in extremely light winds, the generator is temporarily used as a motor when the windmill is stopped, and a small amount of electric power is applied to the windmill to provide initial torque. Has been made and it was quite technically difficult.

  On the other hand, in the case of a vertical axis type windmill, the sound is quiet and the wind in any direction can be received as it is.

However, in the case of a vertical axis type windmill, since the wind that rotates the windmill in the forward rotation direction (the direction in which power generation is performed) and the wind that impedes the rotation of the windmill are simultaneously received, However, there is a problem that the power generation efficiency is low because the torque that always reversely rotates the windmill also acts.
Further, in the case of a storm or the like, the windmill may be damaged due to abnormal high-speed rotation or the generator may be damaged, and there is much room for improvement.

  The applicant and the inventor of the present application do not know the known patent documents and the known non-patent documents related to the present invention, so the description is omitted.

  The present invention has been made in order to eliminate the above-described drawbacks of the prior art, and an object of the present invention is to provide a wind turbine generator for generating power by transmitting rotation of a vertical axis wind turbine to a generator. A cylindrical body that is formed in a cylindrical shape so that it can be placed on the outer peripheral surface and a ventilation window is formed on the outer peripheral surface, and a wind that is arranged on the ventilation window and that winds forwardly rotates the windmill to the ventilation window and prevents the windmill from rotating forward.

  Still another object of the present invention is to provide an opening / closing device in which the wing member can be opened and closed, and the amount of wind introduced into the ventilation window can be adjusted by changing the opening degree of the wing member according to the wind speed. By restricting the rotation speed of the windmill when the wind is particularly strong as in a storm, or stopping the windmill, preventing the windmill and the generator from being damaged, and improving the wind resistance strength of the wind turbine generator .

  Another object of the present invention is to provide an opening / closing device in which the elastic body attached to the wing member is deformed according to the wind speed and the opening degree of the wing member is automatically changed. When the wind speed becomes very high, the opening of the wing member is reduced according to the strength of the wind to suppress the wind hitting the windmill, and when the wind speed returns to normal, it automatically returns to the original opening, An object of the present invention is to obtain a wind power generator with high safety against strong winds by using an inexpensive mechanism so that the rotational speed of the windmill can be suppressed and the windmill can be automatically stopped using the elastic force of the elastic body.

  Still another object is that, in the above-described configuration, the opening / closing device is wound around a motor that operates in accordance with the wind speed, a pulley that is attached to the shaft of the motor, and all pulleys that are attached to the support shaft of the wing member. Endless winding transmission member, and by opening and closing all the wing members synchronously, the opening degree of the wing members can be freely controlled according to the wind speed, even under some strong winds In addition to being able to continue wind power generation, it is possible to protect the wind power generation equipment by stopping the windmill if necessary, and this makes wind power generation steady regardless of the strength of the wind. Is to be able to do it automatically.

  In short, the present invention (Claim 1) is a wind power generator for generating electric power by transmitting rotation of a vertical axis type windmill to a generator, and is formed in a cylindrical shape so as to be covered on the windmill. And a wing member that is arranged in the ventilation window and that guides wind that normally rotates the windmill to the ventilation window and blocks wind that prevents the windmill from rotating forward. Is.

  Further, the present invention (Claim 2) is a wind power generator for generating electric power by transmitting rotation of a vertical axis type windmill to a generator, and is formed in a cylindrical shape so as to be covered on the windmill. A cylindrical body having a plurality of ventilation windows formed thereon, and a wing member that is disposed on each of the ventilation windows and that guides wind that normally rotates the windmill to the ventilation windows and blocks wind that prevents the windmill from rotating forward. In addition, not only the wing member but also a cross between the ventilation windows is used to block the wind that prevents the wind turbine from rotating forward.

  Further, according to the present invention (Claim 3), in a wind turbine generator that generates power by transmitting the rotation of a vertical axis wind turbine to a generator, the wind turbine generator is formed in a cylindrical shape so as to be covered on the wind turbine, and the entire circumference of the outer peripheral surface. A cylindrical body having a plurality of ventilation windows formed therein, and a wind that is disposed in the ventilation windows so as to be openable and closable, and has an area equivalent to an opening area of the ventilation windows and that rotates the windmill forward. A wing member that blocks wind that prevents the wind turbine from rotating forward; and an opening and closing device that adjusts an amount of wind introduced into the ventilation window by changing an opening degree of the wing member according to wind speed. It is a feature.

  The present invention (Claim 4) is characterized in that the opening / closing device is configured such that an elastic body attached to the wing member is deformed according to wind speed to change the opening degree of the wing member. It is what.

  According to the present invention (Claim 5), the opening / closing device is wound around a motor that operates in accordance with the wind speed, a pulley attached to the shaft of the motor, and all pulleys attached to the support shaft of the blade member. And an endless winding transmission member that is hung, and is configured such that all the wing members can be opened and closed synchronously.

  The present invention is a wind power generator that generates power by transmitting the rotation of a vertical axis windmill to a generator as described above, and is formed in a cylindrical shape so that the windmill can be covered, and a ventilation window is formed on the outer peripheral surface. And a wing member that is arranged in the ventilation window and that guides the wind that rotates the windmill in the forward direction to the ventilation window and blocks the wind that prevents the windmill from rotating forward, efficiently transmits wind force to the windmill. As a result, there is an effect that the windmill starts and rotates even in a weak wind without giving an initial torque by special electrical operation, and the effect of improving the efficiency of wind power generation is obtained. It is done.

  Also, in the above configuration, a plurality of ventilation windows are formed on the entire circumference of the outer peripheral surface, and not only the blade member but also a cross between the ventilation windows is used to block the wind that prevents the wind turbine from rotating forward. There is an effect that the wind can be intensively guided so that the windmill rotates forward even with a weaker wind.

  Further, in the above configuration, the wing member is disposed so as to be openable and closable, and includes an opening and closing device that can adjust the amount of wind introduced into the ventilation window by changing the opening degree of the wing member according to the wind speed. Thus, when the wind is particularly strong, there is an effect of limiting the rotation speed of the windmill or stopping the windmill and preventing the windmill and the generator from being damaged, and as a result, improving the wind resistance strength of the wind turbine generator. There is an effect that can be achieved.

  In the above configuration, since the opening / closing device is configured so that the elastic body attached to the wing member is deformed according to the wind speed and the opening degree of the wing member is automatically changed, the wind speed becomes very high during a storm. In this case, the opening of the wing member is reduced according to the strength of the wind to suppress the wind hitting the windmill, and when the wind speed returns to normal, it automatically returns to the original opening, and the rotation speed of the windmill is suppressed. Since the wind turbine can be automatically stopped using the elastic force of the elastic body, it is possible to obtain a wind power generator having high safety against strong winds with an inexpensive mechanism.

  Further, in the above configuration, the opening / closing device is an endless coil wound around a motor that operates according to the wind speed, a pulley attached to the shaft of the motor, and all the pulleys attached to the support shaft of the wing member. Since it has a winding transmission member and all wing members can be opened and closed synchronously, the opening degree of the wing members can be freely controlled according to the wind speed, and wind power generation can be continued even under a certain strong wind, If necessary, the wind turbine can be stopped to protect the wind power generation apparatus, and as a result, wind power generation can be performed constantly without being influenced by the strength of the wind.

  Hereinafter, the present invention will be described based on embodiments shown in the drawings. A wind power generator 10 according to a first embodiment of the present invention includes a cylindrical body 11, a wing member 12, an opening / closing device 13, a vertical axis windmill 14, and a generator 22 in FIGS. It has.

  As shown in FIGS. 1 to 4, the cylindrical body 11 is formed in a cylindrical shape so as to be covered with a vertical axis type windmill 14, and a plurality of ventilation windows 11 a are formed on the entire circumference of the outer peripheral surface. For example, it is formed in a cylindrical shape, its upper end is closed by a lid 15, and its lower end is fixed to a base 16.

  The ventilation window 11a is formed in, for example, a quadrangle, for example, and is equally formed at eight places. Each ventilation window 11a is desirably opened as large as possible. This is because it can capture a lot of wind.

  Since a plurality of ventilation windows 11a are formed, a cross wind shielding bill 11b exists between the adjacent ventilation windows 11a.

  As shown in FIG. 4, the shaft 14 a of the wind turbine 14 passes through the center of the lid 15 of the cylindrical body 11, and a bearing 18 that supports the shaft 14 a is attached by a bearing retainer 19. The bearing 18 and the bearing retainer 19 are covered with a cover 20, sealed to prevent rain and dust from entering, and fixed to the base 16.

  The bottom portion 11 c of the cylindrical body 11 is in contact with the base 16, and the shaft 14 a of the windmill 14 passes through the center of the bottom portion 11 c and the base 16 and is supported by the bearing 18. The bearing 18 is fixed to the base 16 by a bearing retainer 19.

  A generator 22 is attached below the shaft 14 a coaxially using a bracket 21, and the shaft 22 a and the shaft 14 a of the generator 22 are connected via a coupling 23. The generator 22 is attached so as to fit inside the base 16 formed in a truncated cone shape, for example.

  In the present embodiment, the windmill 14 is configured by, for example, attaching wings 14c having a circular cross section to the outer peripheral surface of a cylindrical body 14b. The type of the windmill 14 is not limited to this, and may be of a vertical axis type, and may be a paddle type windmill, a Saponius type windmill, an S type windmill, a gyromill type windmill, or a Darius type windmill, and a sirocco fan. It may be used (both not shown).

  The wing member 12 is disposed in the ventilation window 11a so as to be openable and closable. The wing member 12 has an area equivalent to the opening area of the ventilation window 11a, and guides the wind to the ventilation window 11a that rotates the windmill 14 in the forward direction. For example, it is attached to the left end of the ventilation window 11a so as to be openable and closable within a predetermined angle range (for example, the maximum opening is 60 °).

  Each wing member 12 is fixed to a support shaft 24, and the support shaft 24 is pivotally supported by, for example, a bearing portion 11d provided at the left end of the ventilation window 11a. Lower portions of the support shafts 24 respectively penetrate the base 16, and toothed pulleys 25 are respectively attached to lower ends in the base.

  As shown in FIGS. 4 and 5, the opening / closing device 13 changes the opening degree of the wing member 12 according to the wind speed and makes it possible to adjust the amount of the wind 4 introduced into the ventilation window 11a. A motor 26 and a toothed belt 28 as an example of a winding transmission member are provided, and all the wing members 12 can be opened and closed synchronously.

  The motor 26 is, for example, a pulse motor configured to operate according to the wind speed or the generated voltage generated by the generator 22, and the rotation angle and the rotation direction are controlled by the control unit 27 in FIG. 17. It is attached to the base 16 via a bracket 29. A toothed pulley 30 is attached to a shaft (not shown) of the motor 26.

  The toothed belt 28 is wound around a toothed pulley 30 as an example of a pulley attached to the shaft of the motor 26 and a toothed pulley 25 as an example of all the pulleys attached to the support shaft 24 of the wing member 12. It is an endless belt.

  Tension rollers 31 are disposed between the adjacent toothed pulleys 25 and between the toothed pulleys 25 and the toothed pulleys 30 to effectively mesh the toothed pulleys 25, 30 and the toothed belt 28. At the same time, a constant tension is applied to the toothed belt 28. The tension is adjusted by sliding the support member 32 to which each tension roller 31 is attached.

  Next, in FIG. 12 and FIG. 13, the wind power generator 42 according to the second embodiment of the present invention includes a cylindrical body 11, a wing member 12, a vertical shaft type windmill 14, and a generator (not shown). 3) and an opening / closing device 43.

  The opening / closing device 43 is configured such that the torsion spring 44, which is an example of an elastic body attached to the wing member 12, is deformed according to the wind speed and the opening degree of the wing member 12 is changed.

  For example, two torsion springs 44 are mounted on the same axis of the support shaft 45 of the wing member 12 so as to be sandwiched between the bearing portion 11 d and the washer 46, and one end 44 a is fixed to the cylindrical body 11. The other end 44b is hooked on the wing member 12, and is biased in the direction of opening the wing member 12. The washer 46 is fixed to the upper and lower ends of the support shaft 45 by nuts 48.

  The maximum opening of the wing member 12 is, for example, 60 °, but the maximum opening is limited by, for example, forming a stopper (not shown) on the wing member 12 or providing a separate stopper.

  Since the other parts are the same as those of the first embodiment of the present invention, the same parts are denoted by the same reference numerals and the description thereof is omitted.

  1, 2, and 16, when the wind power generators 10, 42 are attached to the upper end of the pole 33, the attachment 34 is attached to the upper end of the ball 33, and the base is placed on the attachment 34. What is necessary is just to fix the stand 16, and when attaching to the roof 36 of the house 35 as shown in FIG. 17, for example, the stand 38 is attached to this roof 36, and the base 16 is fixed to this stand 38. What should I do?

  The present invention is configured as described above, and the operation thereof will be described below. First, the operation of the wind turbine generator 10 according to the first embodiment of the present invention will be described. In FIG. 6, when the wing member 12 is open, for example, when the wind 4 blows in the direction of the arrow N from the north, the tubular body Of the wind 4 that hits 11, the right half of the wind in the drawing is guided in the cylindrical body 11 in the direction of arrow I from the ventilation window 11a that is guided to the wing member 12 and the crosspiece 11b and located on the north side and the northeast side. to go into. Since the region sandwiched between the two adjacent wing members 12 becomes gradually narrower as it approaches the ventilation window 11a, there is an effect of increasing the wind speed of the wind 4.

  The accelerated wind 4 pushes the blades 14 c of the windmill 14, so that the windmill 14 rotates vigorously in the normal rotation direction, that is, the arrow G direction, and power generation by the generator 22 is performed. The wind 4 that has rotated the windmill 14 goes out of the cylindrical body 11 in the direction of the arrow O so as to be sucked out by the negative pressure around the ventilation window 11a located near the south side.

  On the other hand, of the wind 4 hitting the cylindrical body 11, the wind 4 in the left half on the drawing is blocked by the wing member 12 and the crosspiece 11b, and the cylinder from the ventilation window 11a, contrary to the wind 4 in the right half 4. It hardly enters the body 11 and escapes to the left (west) in the figure.

  That is, as shown in FIG. 7, approximately the left half of the cylindrical body 11 is a large region 50 where the wind 4 that prevents the wind turbine 14 from rotating forward is not blown. In the right half of the cylindrical body 11, the vicinity of the north and northeast ventilation windows 11 a is a region 51 that blows in a state where the wind 4 that rotates the windmill 14 in a positive direction is accelerated.

  The wind turbine generator 10 can take advantage of the characteristics of a vertical axis wind turbine that can be used regardless of the wind direction. In FIG. 8, for example, when the wind 4 is blowing from the west in the arrow W direction, The wind 4 in the upper half is guided to the wing member 12 and the crosspiece 11b and enters the cylindrical body 11 in the direction of arrow I from the ventilation window 11a located on the west side and the northwest side, and the windmill 14 is vigorously moved in the direction of arrow G. Rotate. Since the wind 4 in the lower half of the drawing is blocked by the wing member 12 and the crosspiece 11b and cannot enter the cylindrical body 11, almost no torque that reversely rotates the windmill 14 is generated.

  In FIG. 9, for example, when the wind 4 is blowing from the south in the direction of the arrow S, the wind 4 in the left half of the drawing is led to the wing member 12 and the crosspiece 11b and is located on the south side and the southwest side. The wind turbine 14 is vigorously rotated in the arrow G direction by entering the cylindrical body 11 from the window 11a in the arrow I direction. The wind 4 in the right half of the drawing is blocked by the wing member 12 and the crosspiece 11b and cannot enter the cylindrical body 11, so that almost no torque that reversely rotates the windmill 14 is generated.

  In FIG. 10, for example, when the wind 4 is blowing from the east in the direction of arrow E, the lower half of the wind 4 in the drawing is guided to the wing member 12 and the crosspiece 11b and is located on the east side and the southeast side. The wind turbine 14 is vigorously rotated in the arrow G direction by entering the cylindrical body 11 from the window 11a in the arrow I direction. The wind 4 in the upper half of the drawing is blocked by the wing member 12 and the crosspiece 11b and cannot enter the cylindrical body 11, so that almost no torque that reversely rotates the windmill 14 is generated.

  During a storm such as a typhoon, when a certain wind speed is exceeded, for example, when the output voltage from the generator 22 exceeds a certain value, the control unit 27 supplies the voltage as shown in FIGS. This is detected and the motor 26 of the switchgear 13 is operated.

  The opening degree of the wing member 12 is normally in the most open state at 60 °, for example, but when the wind speed exceeds a certain value, the opening degree is gradually reduced and is controlled to become 0 ° in due course. Note that this diagram is merely an example, and how the opening degree of the wing member 12 is controlled is arbitrary.

  Specifically, when the motor 26 rotates by a predetermined angle in the arrow F direction, the toothed pulley 30 drives the toothed belt 28 in the arrow J direction. Then, all the toothed pulleys 25 attached to the support shaft 24 of the wing member 12 are rotated in the direction of the arrow K in synchronization with each other, and accordingly, the wing member 12 is rotated in the direction of the arrow K. The opening degree of the blade member 12 decreases according to the rotation angle of the motor 26, and eventually the opening degree becomes 0 °.

  Conversely, when the motor 26 rotates in the arrow H direction, the toothed pulley 30 drives the toothed belt 28 in the arrow L direction. Then, all the toothed pulleys 25 attached to the support shaft 24 of the wing member 12 are rotated in the direction of the arrow M in synchronization with each other, and the wing member 12 is rotated in the direction of the arrow M accordingly. Depending on the rotation angle of the motor 26, the opening degree of the blade member 12 increases, and the opening degree is 60 ° at the maximum.

  In the case of a bare windmill, there is a concern that the rotational speed of the windmill will increase too much and the generator and the like may be broken. However, in the case of the wind power generator 10 according to the present invention, the wing member 12 can be By automatically adjusting the opening degree, the rotational speed of the windmill 14 can be appropriately suppressed, and wind power generation can be continuously performed without wasting precious winds. It is possible to stop the windmill 14 as necessary.

  In the case of the wind power generator 42 according to the second embodiment of the present invention, as shown in FIGS. 12 and 13, when the wind speed increases, the wing member 12 receiving wind from the front by the wind pressure is provided. It automatically rotates against the torsion spring 44 and narrows the ventilation window 11a.

  As a result, the amount of wind entering the cylindrical body 11 is reduced, so that the power generation can be continued while suppressing the rotational speed of the windmill 14 even under strong winds. When the wind direction changes or the wind weakens, the wing member 12 automatically rotates in the opening direction by the elastic force of the torsion spring 44. Normally, it immediately returns to the maximum opening.

  The operation of introducing and blocking the wind to the tubular body 11 at normal times is the same as that of the first embodiment of the present invention.

Since the wind power generation apparatus 10 according to the first embodiment and the wind power generation apparatus 42 according to the second embodiment capture the wind skillfully as described above, the rotational efficiency is very high, and therefore extremely small wind The windmill 4 can be started and rotated, and as shown in FIGS. 16 and 17, both can be installed on the pole 33 and can be used in a very narrow installation place. There are very few dangers and noise problems to the surroundings compared to the conventional example.
It can also be used by being installed on the roof 36 of the house 35. In order to improve the output, for example, a plurality of devices can be installed side by side in the vertical direction or the horizontal direction.
