It is a wind power generator developed from knowledge and uses wind power effectively.

Patent No.5731048

As an invention that effectively uses wind power, the technique disclosed in Patent Document 1 has a tadpole-shaped blade at the outer end of a radial horizontal arm a extending from the central axis 1 as shown in FIG. An invention has been proposed in which the generator is rotated by the rotation of the windmill W provided with 2.
However, with such a structure, as described above, sufficient wind power generation cannot be performed in a poorly ventilated place.
The technical problem of the present invention pays attention to such a problem, and it is technical to use a wind power generator with the same output and size as a normal type installed on the ground for use in a high airspace. However, there are many problems in the environment, so it is impossible to realize it, so if the altitude increases by maintaining the same output as the normal type of the normal specification and pursuing further downsizing, the wind speed is easier to obtain than the lowland Benefits or an efficient wind generator that can effectively use wind power.

The technical problem of the present invention is solved by the following means. Claim 1 is a wind turbine in which a main wing circulates around a vertical central axis, and an inclined plate that strikes a side wind coming to the side surface of the wind turbine is provided between adjacent main wings so that the wind of the cross wind is circulated by the wind turbine It is a wind power generator characterized by having a structure converted into force.

According to a second aspect of the present invention, the inclined plate is provided between adjacent main wings or between the adjacent main wings closer to the center of rotation than the main wings. Wind power generator.

The third aspect of the present invention is characterized in that the wind turbine of the wind power generator is installed in an installation portion provided on the upper end of the electric pole of the streetlight, the upper end of the pole, the high-rise wall type, or the rooftop balcony. It is a wind power generator as described in.

According to a fourth aspect of the present invention, there is provided a polygonal shutter having an even number of planar shapes surrounding at least the outer periphery of the windmill, and the shutter can be opened and closed when a strong wind arrives. A wind power generator according to claim 2 or claim 3.

According to a fifth aspect of the present invention, the shutter can be rotated around a central axis of the windmill, and includes a 180 ° direction wind plate provided at one corner of the polygon and 180 degrees and / or the windmill. The wind power generator according to any one of claims 1 to 4, wherein the incoming wind is divided into two parts.

As in claim 1, a wind turbine in which a main wing circulates around a vertical central axis, and at least one inclined plate that strikes a side wind arriving on a side surface of the wind turbine is provided between adjacent main wings. Since the wind power is converted into the circulatory force of the windmill, the circulatory force rotates the windmill to drive the generator.

As described in claim 2, the inclined plate is provided between the main wings, or is provided closer to the center of rotation than the main wings between the main wings. The windmill can rotate and generate electricity even in light winds.

Since the wind turbine of the wind power generator is installed in the installation part provided on the upper end of the streetlight pole, the upper end of the pole, the high-rise wall type or the rooftop balcony as in claim 3, the installation position of the wind turbine is high, and the ventilation is Since the windmill is improved, the windmill rotates smoothly and reliably in combination with the structure of the windmill that captures even a breeze and converts it into rotational force.

According to the fourth aspect of the present invention, there is provided an even polygonal shutter that surrounds at least the outer periphery of the windmill, and the shutter can be opened and closed when a strong wind arrives. When it arrives, by closing the shutter in advance, it is possible to protect the internal windmill and prevent damage.

According to a fifth aspect of the present invention, the shutter is capable of rotating around the center axis of the windmill, and includes a 180 ° direction wind direction plate provided at one corner of the polygon and 180 degrees and / or the windmill. Since the incoming wind is divided into two, even if a strong wind such as a typhoon arrives, the shutter automatically rotates and the wind direction plate faces the incoming wind and diverts the incoming wind in half. Therefore, the wind pressure received by the shutter is minimized, and damage is avoided.

Next, an embodiment of how the wind power generator according to the present invention is actualized will be described. FIG. 2 is a front view showing a normal type windmill W provided on the ground, and a tadpole blade 2 is provided on the outer end of a radial horizontal arm a extending from the central axis 1 when viewed in plan view. . The vertical axis type windmill W having such a shape generates electric power by rotationally driving a generator (not shown).

Such a normal type windmill is downsized or windmills that can effectively capture and rotate even with weak wind power are raised and installed at high places with wind. FIG. 3 shows a type in which a windmill W is provided on a pole P, and types of 200 w to 5 kw are used. The pole P has a large-diameter cylindrical shape. A windmill W is installed at the upper end, and a reinforcing brace 3 is provided obliquely between the pole P and the windmill installation floor.
FIG. 4 is a front view showing another embodiment of a type in which a windmill W is provided on the pole P2, and the large-diameter cylindrical pole P2 is made higher so as to correspond to a high layer. The main specifications are 10kw and 20kw types.
FIG. 5 is a front view of a type in which a windmill W is provided on a high-rise wall composed of four columns P3, and is assembled and completed on a rooftop balcony or the like. The main specifications do not use the body frame used in the pole specifications or high-rise pole specifications, but are assembled after being disassembled. Therefore, it can be used according to the application and scale to be used, and can be used in all models.

このように使用する環境毎に、最適な組合せを選択でき、用途の変更も容易である。 Reference is made to Table 1, which compares the numerical values of each type of vertical axis wind power generator.

Thus, the optimal combination can be selected for each environment to be used, and the application can be easily changed.

In addition, the features of the vertical axis type wind power generator of the same output vertical axis type wind power generator compact type (high-rise roof & rooftop balcony) type are as follows.
(1) Comparing the wind turbines used for general vertical axis wind power generators and the wind turbines used for high-rise roof and rooftop balcony specifications, the size of the normal vertical axis wind turbine with the same output is 100%. The vertical axis type with roof and rooftop balcony can be downsized by 40% to 60%.
One of the factors is that the normal type vertical axis wind power generator is installed in a low altitude area and is unstable depending on the strength of the wind speed. However, a windmill is installed in the high altitude area as much as possible. This is because there is a high probability that a relatively stable wind speed will be obtained compared to the low-altitude area, and the density of the wind included in the low-altitude area and the high-altitude area will also be high. Therefore, there is an advantage that it is smaller than a normal normal type windmill size.
Of course, it is not possible to install a normal-sized object that is installed and used in a low altitude area in a high altitude area, and the danger increases. The marketability of vertical axis wind power generators will be further expanded by downsizing.

(2) One challenge that occurred in developing a vertical axis wind generator with a high-rise roof and rooftop balcony that can be used in a smaller size than a normal vertical axis wind generator with the same output Since the required area of the blades to be received is naturally limited by downsizing, the main blade of (1) is a variable main wing whose purpose is to adjust the angle according to the installation location. The vertical axis blades have the disadvantage that the blades change vertically and horizontally and vertically by rotating in response to the wind, so the variable main wing causes lateral blurring during rotation, and the vertical balance that is the life of the vertical axis is destroyed. For the purpose of reducing the performance as much as possible, the auxiliary rod is installed between the main variable wing blades. Use it only to prevent horizontal wrinkles In the center of the rod for preventing the main blade lateral blurring, which is installed in two stages above and below, to compensate for the lack of blade area required for the normal vertical axis wind power with the same output. By installing the fixed auxiliary wings (width 200 to 400mm) of (2), one of the challenges in the development of miniaturization has been cleared. This is a vertical axis wind power generator with a roof and rooftop balcony. Naturally, since it is a rod for preventing lateral blurring of (2), which is installed to prevent lateral blurring of the variable main wing which is the main of (1), it is installed at the center of that rod (2) Unlike the variable main wing blade of (1), the auxiliary wing is fixed.

FIG. 6 and subsequent figures are wind turbines that can capture and rotate even with light wind, and FIG. 6 shows an embodiment in which the angle of the main wing blade 2 can be varied. The generator is rotated by the rotation of a windmill W in which a tadpole blade 2 is connected to the outer end of a radial horizontal arm a extending from the central shaft 1 by a support shaft when viewed in a plan view. As shown in FIG. 7, the main wing blade 2 can change the angle within a range of several degrees by expanding and contracting the telescopic rod R disposed obliquely between the front side and the horizontal arm a.
A concave key 6 for trapping wind pressure is formed at the tip of the auxiliary blade 5 provided so as to close the side surface of the wind turbine at the position of the connecting bar 4 that connects the tips of the adjacent horizontal arms a and a. 7 is inclined. Therefore, in addition to the rotation of the windmill W by the blades 2, the windmill W is rotated by the concave key 6 and the inclined plate 7 of the sub blade 5, so that the windmill W can be rotated even in a slight wind and can be easily moved to a higher level. become.

In FIG. 6, the auxiliary blade 5 exists only between the concave key 6 and the inclined plate 7, but in FIG. 8, there is a lateral wind receiving wall 5 ′ having a wider width. 6 may be curved similarly to the cross wind receiving wall 5 'and has the same height as the blade 2. FIG. 9 is a perspective view, and a V-shaped concave key 6 for capturing wind pressure is formed at the front end of the horizontal wind receiving wall 5 ′ slightly behind the tail end 21 of the blade 2, and the rear end advances the wind of the cross wind. The inclined plate 7 is used to convert it into force. The edge of the inclined tail end 7 protrudes into the window hole h through which the cross wind can pass. Therefore, a side wind enters the concave key 6 to rotate the windmill W, and a pressing force is applied by the inclined plate 7 at the tail end, so that the rotation of the windmill W by the main wing blade 2 becomes smoother and the windmill can be moved even in a slight wind. It can be rotated.

Since various embodiments of the cross wind receiving wall 5 'are possible, they will be exemplified below. (1) The number of the inclined plates 7 may be only one. However, if a plurality of plates such as two or three are used, the pressing force is doubled and tripled, and the rotational power of the windmill is also increased. A structure in which the V-shaped concave key 6 for capturing wind pressure is not provided is also possible. Each of these embodiments is illustrated in FIG.

8 and 9, the cross wind capturing wall 5 is located on the same circumference as the outer end of the horizontal arm a, whereas FIGS. 10 and 11 are closer to the central axis 1 than the tip of the horizontal arm a. The crosswind capture wall 5 is shifted to a position where it has moved somewhat. FIG. 11 is a perspective view, and since the area of the main wing blade 2 and the side wind receiving wall 5 is large, it can also be used as an advertising surface for displaying that wind power, which is renewable natural energy, is used. For example, it is possible to write letters such as letters of the Paris Agreement and wind power generation that have established an arrangement for preventing global warming.
As shown in FIG. 8 and FIG. 10, the cross wind is guided into the recess 22 at the rear end of the main wing blade 2 by the tail end 21 of the main wing blade 2 and the outer surface of the V-shaped concave key 6, so that the main wing blade 2 is pushed. Wind pressure increases. As described above, when the wind pressure is intermittently increased, it seems to hinder the smooth rotation of the windmill, but since the inertia is always acting, the rotation is smooth.

As shown in the plan view of FIG. 12, a cross wind blade 2 ′ having a tadpole shape like the main wing blade 2 is provided at the tip of the horizontal arm a between the main wing blades 2. In FIG. 7, the telescopic rod R is on the front side of the horizontal arm a, whereas in the embodiment of FIG. 13, the telescopic rod R is on the rear side of the horizontal arm a.

When a strong wind such as a typhoon arrives, a structure that opens and closes a shutter that can protect the windmill in advance is desirable. 14 to 17 show examples of protecting the windmill with the shutter S, and a commercially available brand is sufficient for the shutter S. FIG. 14 is a side view showing a state in which the motor for winding the shutter is remotely operated and the shutter is wound up and opened, and is kept open during normal times when strong wind does not blow. When a strong wind comes, the hoisting motor is remotely operated in advance to open the shutter S and close the opening as shown in FIG. 15 to protect the internal windmill from being damaged. All other aspects are thus protected from strong winds by the shutter S in this way. Although the wind pressure is weak, it may be blown from the upper surface, so that the upper surface can also be closed by the shutter S. That is, during normal times, as shown in FIG. 16, the motor is remotely operated to wind up the shutter S and open it. When there is a possibility that strong winds will blow, the shutter S is closed by remote control of the motor as shown in FIG. 17 to prevent strong winds from hitting the internal windmill.

How to avoid the damage of blades, which is a weak point of wind power generators, is a strong wind-resistant protective shutter. The damage to blades, which is the life of wind power generators, is 80% due to natural strong winds.
This strong wind resistant protective shutter is installed in a high-rise roof type vertical axis wind power generator installed at a height of 10m or more in a high air area where the wind speed is relatively stable or installed in a high air area within 60m. It has been developed for the purpose of protecting the blades of the "Rooftop Balcony Vertical Axis Wind Generator".
In addition, this strong wind resistant protective shutter is arranged in advance when the approach of a typhoon accompanied by a strong wind is caught in advance, and is installed in advance on the outer frame housing frame together with the operation of stopping the windmill from a remote location as the approaching probability increases. By turning on the open / close switch of the strong wind-resistant protective shutter, the shutter is automatically closed, making it possible to protect the blades that are the life of important wind power from damage from strong winds.
Of course, manual opening and closing operations can be performed at the site where it is installed, and the opening and closing operation of this strong wind resistant protective shutter is incorporated into the PLC control system, which is the heart of the operation system of the wind power generator. However, emergency response is possible. Of course, since the shutter can be opened and closed automatically and after the strong wind has left, it is possible to save time and effort for taking care of the strong wind.

An even polygonal frame that integrates a frame that guides and supports the shutters S can be rotated around the center axis of the windmill. The rotating mechanism may have a wheel attached to the lower part of a polygonal frame or a structure in which a grooved wheel runs on a circular rail. And it is set as the structure which has a wind direction board of the 180 degree direction provided in the corner part position of 180 degrees of one and a polygon of the said polygon, and / or a windmill upper part, and an incoming wind is divided into two. In other words, since the polygonal shutter frame functions as a jumbo windcock, even if a strong wind such as a typhoon arrives, the shutter will automatically rotate and the wind direction plate will face the incoming wind and divert the incoming wind in half. Therefore, the wind pressure received by the shutter is minimized, and damage is avoided.

As described above, the windmill is downsized so that the windmill can be installed in high altitude areas with wind. Moreover, despite the downsizing, it also captures crosswinds and realizes efficient wind power generation instead of the rotational force of the windmill. Moreover, since the shutter which surrounds the said windmill is provided and a typhoon comes and closes a shutter and protects a windmill, the problem which the blade | wing of a windmill is damaged is also eliminated.

The high-rise roof type wind power generator developed for the purpose of adapting to high-rise roofs and rooftop balconies cannot be used even if it is desired to install a wind power generator because the wind speed that is the power source of the wind power generator cannot be obtained.

Next, an embodiment of how the wind power generator according to the present invention is actualized will be described. FIG. 2 is a front view showing a normal type windmill W provided on the ground, and a tadpole blade 2 is provided on the outer end of a radial horizontal arm a extending from the central axis 1 when viewed in plan view. . The vertical axis type windmill W having such a shape generates electric power by rotationally driving a generator (not shown).

Such a normal type windmill is downsized or windmills that can effectively capture and rotate even with weak wind power are raised and installed at high places with wind. FIG. 3 shows a type in which a windmill W is provided on a pole P, and types of 200 w to 5 kw are used. The pole P has a large-diameter cylindrical shape. A windmill W is installed at the upper end, and a reinforcing brace 3 is provided obliquely between the pole P and the windmill installation floor.

The main specifications do not use the body frame used in the pole specifications or high-rise pole specifications, but are assembled after being disassembled. Therefore, it can be used according to the application and scale to be used, and can be used in all models.

このように使用する環境毎に、最適な組合せを選択でき、用途の変更も容易である。 Reference is made to Table 1, which compares the numerical values of each type of vertical axis wind power generator.

Thus, the optimal combination can be selected for each environment to be used, and the application can be easily changed.

In addition, the features of the vertical axis type wind power generator of the same output vertical axis type wind power generator compact type (high-rise roof & rooftop balcony) type are as follows.
(1) Comparing the wind turbines used for general vertical axis wind power generators and the wind turbines used for high-rise roof and rooftop balcony specifications, the size of the normal vertical axis wind turbine with the same output is 100%. The vertical axis type with roof and rooftop balcony can be downsized by 40% to 60%.
One of the factors is that the normal type vertical axis wind power generator is installed in a low altitude area and is unstable depending on the strength of the wind speed. However, a windmill is installed in the high altitude area as much as possible. This is because there is a high probability that a relatively stable wind speed will be obtained compared to the low-altitude area, and the density of the wind included in the low-altitude area and the high-altitude area will also be high. Therefore, there is an advantage that it is smaller than a normal normal type windmill size.
Of course, it is not possible to install a normal-sized object that is installed and used in a low altitude area in a high altitude area, and the danger increases. The marketability of vertical axis wind power generators will be further expanded by downsizing.

(2) One challenge that occurred in developing a vertical axis wind generator with a high-rise roof and rooftop balcony that can be used in a smaller size than a normal vertical axis wind generator with the same output Since the required area of the blades to be received is naturally limited by downsizing, the main blade of (1) is a variable main wing whose purpose is to adjust the angle according to the installation location. The vertical axis blades have the disadvantage that the blades change vertically and horizontally and vertically by rotating in response to the wind, so the variable main wing causes lateral blurring during rotation, and the vertical balance that is the life of the vertical axis is destroyed. For the purpose of reducing the performance as much as possible, the auxiliary rod is installed between the main variable wing blades. Use it only to prevent horizontal wrinkles In the center of the rod for preventing the main blade lateral blurring, which is installed in two stages above and below, to compensate for the lack of blade area required for the normal vertical axis wind power with the same output. By installing the fixed auxiliary wings (width 200 to 400mm) of (2), one of the challenges in the development of miniaturization has been cleared. This is a vertical axis wind power generator with a roof and rooftop balcony. Naturally, since it is a rod for preventing lateral blurring of (2), which is installed to prevent lateral blurring of the variable main wing which is the main of (1), it is installed at the center of that rod (2) Unlike the variable main wing blade of (1), the auxiliary wing is fixed.

FIG. 6 and subsequent figures are wind turbines that can capture and rotate even with light wind, and FIG. 6 shows an embodiment in which the angle of the main wing blade 2 can be varied. The generator is rotated by the rotation of a windmill W in which a tadpole blade 2 is connected to the outer end of a radial horizontal arm a extending from the central shaft 1 by a support shaft when viewed in a plan view. As shown in FIG. 7, the main wing blade 2 can change the angle within a range of several degrees by expanding and contracting the telescopic rod R disposed obliquely between the front side and the horizontal arm a.
A concave key 6 for trapping wind pressure is formed at the tip of the auxiliary blade 5 provided so as to close the side surface of the wind turbine at the position of the connecting bar 4 that connects the tips of the adjacent horizontal arms a and a. 7 is inclined. Therefore, in addition to the rotation of the windmill W by the blades 2, the windmill W is rotated by the concave key 6 and the inclined plate 7 of the sub blade 5, so that the windmill W can be rotated even in a slight wind and can be easily moved to a higher level. become.

In FIG. 6, the auxiliary blade 5 exists only between the concave key 6 and the inclined plate 7, but in FIG. 8, there is a lateral wind receiving wall 5 ′ having a wider width. 6 may be curved similarly to the cross wind receiving wall 5 'and has the same height as the blade 2. FIG. 9 is a perspective view, and a V-shaped concave key 6 for capturing wind pressure is formed at the front end of the horizontal wind receiving wall 5 ′ slightly behind the tail end 21 of the blade 2, and the rear end advances the wind of the cross wind. The inclined plate 7 is used to convert it into force. The edge of the inclined tail end 7 protrudes into the window hole h through which the cross wind can pass. Therefore, a side wind enters the concave key 6 to rotate the windmill W, and a pressing force is applied by the inclined plate 7 at the tail end, so that the rotation of the windmill W by the main wing blade 2 becomes smoother and the windmill can be moved even in a slight wind. It can be rotated.

Since various embodiments of the cross wind receiving wall 5 'are possible, they will be exemplified below. (1) The number of the inclined plates 7 may be only one. However, if a plurality of plates such as two or three are used, the pressing force is doubled and tripled, and the rotational power of the windmill is also increased. A structure in which the V-shaped concave key 6 for capturing wind pressure is not provided is also possible. Each of these embodiments is illustrated in FIG.

8 and 9, the cross wind capturing wall 5 is located on the same circumference as the outer end of the horizontal arm a, whereas FIGS. 10 and 11 are closer to the central axis 1 than the tip of the horizontal arm a. The crosswind capture wall 5 is shifted to a position where it has moved somewhat. FIG. 11 is a perspective view, and since the area of the main wing blade 2 and the side wind receiving wall 5 is large, it can also be used as an advertising surface for displaying that wind power, which is renewable natural energy, is used. For example, it is possible to write letters such as letters of the Paris Agreement and wind power generation that have established an arrangement for preventing global warming.
As shown in FIG. 8 and FIG. 10, the cross wind is guided into the recess 22 at the rear end of the main wing blade 2 by the tail end 21 of the main wing blade 2 and the outer surface of the V-shaped concave key 6, so that the main wing blade 2 is pushed. Wind pressure increases. As described above, when the wind pressure is intermittently increased, it seems to hinder the smooth rotation of the windmill, but since the inertia is always acting, the rotation is smooth.

As shown in the plan view of FIG. 12, a cross wind blade 2 ′ having a tadpole shape like the main wing blade 2 is provided at the tip of the horizontal arm a between the main wing blades 2. In FIG. 7, the telescopic rod R is on the front side of the horizontal arm a, whereas in the embodiment of FIG. 13, the telescopic rod R is on the rear side of the horizontal arm a.

When a strong wind such as a typhoon arrives, a structure that opens and closes a shutter that can protect the windmill in advance is desirable. 14-17 is an example of protecting a wind turbine with a shutter S, the shutter S is sufficient for commercial shutter. FIG. 14 is a side view showing a state in which the motor for winding the shutter is remotely operated and the shutter is wound up and opened, and is kept open during normal times when strong wind does not blow. When a strong wind comes, the hoisting motor is remotely operated in advance to open the shutter S and close the opening as shown in FIG. 15 to protect the internal windmill from being damaged. All other aspects are thus protected from strong winds by the shutter S in this way. Although the wind pressure is weak, it may be blown from the upper surface, so that the upper surface can also be closed by the shutter S. That is, during normal times, as shown in FIG. 16, the motor is remotely operated to wind up the shutter S and open it. When there is a possibility that strong winds will blow, the shutter S is closed by remote control of the motor as shown in FIG. 17 to prevent strong winds from hitting the internal windmill.

How to avoid the damage of blades, which is a weak point of wind power generators, is a strong wind-resistant protective shutter. The damage to blades, which is the life of wind power generators, is 80% due to natural strong winds.
This strong wind resistant protective shutter is installed in a high-rise roof type vertical axis wind power generator installed at a height of 10m or more in a high air area where the wind speed is relatively stable or installed in a high air area within 60m. It has been developed for the purpose of protecting the blades of the "Rooftop Balcony Vertical Axis Wind Generator".
In addition, this strong wind resistant protective shutter is arranged in advance when catching the approach of a typhoon with a strong wind, and is installed in advance on the outer frame frame together with the operation of stopping the windmill from a remote location as the probability of approach increases. By turning on the open / close switch of the strong wind-resistant protective shutter, the shutter is automatically closed, making it possible to protect the blades that are the life of an important windmill from damage from strong winds.
Of course, manual opening and closing operations can be performed at the site where it is installed, and the opening and closing operation of this strong wind resistant protective shutter is incorporated into the PLC control system, which is the heart of the operation system of the wind power generator. However, emergency response is possible. Of course, since the shutter can be opened and closed automatically and after the strong wind has left, it is possible to save time and effort for taking care of the strong wind.

An even polygonal frame that integrates a frame that guides and supports the shutters S can be rotated around the center axis of the windmill. The rotating mechanism may have a wheel attached to the lower part of a polygonal frame or a structure in which a grooved wheel runs on a circular rail. The one and 180 degree corner position of the polygon, and / or a wind direction plate in the direction of 180 degrees which is provided on the windmill upper shall be the structure in which incoming air is divided. In other words, since the polygonal shutter frame functions as a jumbo windcock, even if a strong wind such as a typhoon arrives, the shutter will automatically rotate and the wind direction plate will face the incoming wind and divert the incoming wind in half. Therefore, the wind pressure received by the shutter is minimized, and damage is avoided.

As described above, the windmill is downsized so that the windmill can be installed in high altitude areas with wind. Moreover, despite the downsizing, it also captures crosswinds and realizes efficient wind power generation instead of the rotational force of the windmill. Moreover, since the shutter which surrounds the said windmill is provided and a typhoon comes and closes a shutter and protects a windmill, the problem which the blade | wing of a windmill is damaged is also eliminated.
