Description

  The present invention relates to a wind turbine generator that drives a generator using a windmill.

    Conventionally, the air discharged from the cooling fan of the cooling tower, that is, the exhaust air, has been used only for delaying the dropping speed of the sprayed water droplets to dissipate heat, and not for other purposes. This is a waste of exhaust air.

    Therefore, the propeller-type generator rotor, which is one of the horizontal axis wind turbines, is driven using the exhaust air of the cooling fan of the cooling tower, or the exhaust air deflected by the deflection hood that deflects the upward exhaust air sideways is used. There has been proposed a wind turbine generator that generates power by driving a vertical axis wind turbine arranged in a vertical direction so as to be received (see Patent Documents 1 to 6).

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

<Example 1>
As shown in FIGS. 1, 4, 6, and 7, the wind turbine generator according to this embodiment is an example of a hybrid wind turbine generator. The hybrid wind power generator is attached to the windmill mounting frame 4. The windmill mounting frame 4 is installed by using a foundation 3 for installing a cooling tower 2 having a cooling fan 1 that delays the dropping speed of sprayed water droplets and dissipates heat on the roof of a building. The windmill mounting frame 4 includes a vertical frame 4a, an intermediate horizontal frame 4b, and a top horizontal frame 4c.

  The vertical frame 4a has a vertical member erected at the corners of a plane quadrangle or a triangle. The intermediate horizontal frame 4b is provided inside the vertical frame 4a and has a plurality of horizontal members. The outer ends of the horizontal members are connected to the intermediate points of the vertical members, and the inner ends are connected to each other. Is or is close. The top horizontal frame 4c is composed of a plurality of horizontal members arranged on the upper side of the intermediate horizontal frame. The outer end of the horizontal member is coupled to the top of the vertical member of the vertical frame, and the inner ends are coupled to each other.

  The hybrid wind power generator has a double wind turbine including a vertical axis wind turbine 5 and a horizontal axis wind turbine 6. The double wind turbine is mounted on the wind turbine mounting frame 4 above the cooling fan 1. The vertical axis windmill 5 and the horizontal axis windmill 6 have a common vertical rotation axis 11. Further, in the hybrid wind turbine generator, the horizontal axis wind turbine 6 receives the upward exhaust air 7 from the cooling fan 1 when the cooling tower 2 is operated, and the vertical axis wind turbine 5 receives the natural wind 8 when the cooling tower 2 is stopped. A double wind turbine, that is, a generator 9 driven by the cooperation of the vertical axis wind turbine 5 and the horizontal axis wind turbine 6 is provided (FIGS. 1 to 3).

  The vertical axis wind turbine 5 is configured by concentrically arranging a plurality of vertical blades 10 around a vertical rotating shaft 11. The vertical rotating shaft 11 is installed in the same direction as the wind direction of the exhaust air. Therefore, the vertical axis wind turbine 5 is not affected by the wind direction of the natural wind and is rotated by the natural wind in any direction (FIGS. 2 to 3).

  The vertical axis windmill 5 is provided outside the horizontal axis windmill 6.

  The vertical rotating shaft 11 of the compound wind turbine and the rotating shaft 12 of the cooling fan 1 are located on a common vertical line.

  The vertical axis wind turbine 5 has a blade whose central rotational axis is orthogonal to the wind direction, and any of a cross flow type, a Darius type, a gyro mill type, a Savonius type, an S type rotor type, a paddle type, etc. may be used. Good (“Tocoton-friendly wind power generation book”, Chapter 4 “Types and usage of windmills”, published on January 20, 2010, first edition, Nikkan Kogyo Shimbun).

  Compared with the horizontal axis wind turbine 6, the vertical axis wind turbine 5 can use wind in any direction regardless of the wind direction, and therefore, no wind direction control device is required, and there is less wind noise and noise problems are reduced. In addition, there is an advantage that it can be installed in a downtown area, a condominium, and an apartment house area.

  As the vertical axis wind turbine 5, it is preferable to adopt a gyro mill type.

  The horizontal axis wind turbine 6 has blades with a central rotational axis parallel to the wind direction, and is composed of a propeller type, a multi-blade type, a sail wing type, a pinwheel type, a ribbon type, a Dutch type, etc. Easy Wind Power Book ”, Chapter 4“ Types and Usage of Windmills ”, published on January 20, 2010, the first edition, Nikkan Kogyo Shimbun).

  The horizontal axis wind turbine 6 has an advantage that a relatively large torque can be obtained because of the use of wind drag, but depends on the wind direction, and therefore requires a wind direction control device. In the hybrid wind turbine generator of the present invention, however, Since the upward exhaust air from the cooling tower 2 is received, the air direction is constant, and a wind direction control device is unnecessary.

  The horizontal axis wind turbine 6 is preferably a propeller type.

  In the above embodiment, one end of the vertical rotation shaft 11 is directly connected to the drive shaft of the generator 9. The generator 9 is attached to the joint portion of the cross member of the top horizontal frame 4c. The other end of the vertical rotating shaft 11 is rotatably supported by a bearing provided at a cross member coupling portion of the intermediate horizontal frame 4b. However, the vertical rotation shaft 11 can be connected to the drive shaft of the generator 9 via a transmission mechanism such as a belt and a gear ring, and the rotational speed of the drive shaft of the generator 9 is changed by changing the transmission ratio of the transmission mechanism. It is also possible.

  Moreover, since the hybrid wind power generator is installed at the top of a building or the like, it is preferable to install a protective net in order to protect birds and protect from flying objects.

  Moreover, it is preferable to install a stopper (brake) for stopping the rotation of the vertical axis wind turbine 5 for maintenance and risk prevention. That is, when repairing and maintaining the cooling tower 2 and the blades for wind power generation, it is necessary to provide a safety structure in which a brake is installed to stop the rotating object (blade). Even if the wind turbine itself is braked to prevent breakage due to strong winds, the blades are only stopped at that time, so that the operating state of the cooling tower 2 is not affected.

<Example 2>
As shown in FIGS. 4 to 7, the hybrid wind power generator according to the present embodiment has a cooling tower 2 having a cooling fan 1 that delays the dropping speed of sprayed water droplets and dissipates heat on the roof of the building. A windmill mounting frame 4 is mounted using a foundation 3 for the purpose.

  In this embodiment, the vertical axis windmill 5 is arranged on the windmill mounting frame 4 above the cooling fan 1 so that the vertical rotation shaft 11 is in the vertical direction, and the vertical axis windmill 5 is connected to the vertical rotation shaft 11. The arm 12 forms a horizontal axis wind turbine 6a in which the vertical rotation shaft 11 is arranged in the vertical direction. When the cooling tower 2 is operated, the horizontal axis wind turbine 6 a receives the upward exhaust air 7 from the cooling fan 1, and when the cooling tower 2 is stopped, the vertical axis wind turbine 5 receives the natural wind 8 and is horizontal with the vertical axis wind turbine 5. A generator 9 driven by the cooperation of the axial wind turbine 6a is provided.

  In this embodiment, the vertical axis wind turbine 5 is composed of a plurality of vertical blades 10 provided concentrically around the vertical rotation shaft 11, and the vertical rotation shaft 11 is installed in the same direction as the wind direction of the exhaust air. The vertical rotation shaft 11 is arranged in the vertical direction so that it can rotate with respect to the natural wind in any direction regardless of the direction of the natural wind.

  According to the embodiment in which the horizontal axis wind turbine 6a in which the vertical rotation shaft 11 is arranged in the vertical direction is formed by the arm 12 that connects the vertical axis wind turbine 5 to the vertical rotation shaft 11, the vertical axis wind turbine and the horizontal axis wind turbine are constructed. Becomes simple and easy to install in the cooling tower.

  In the wind power generator described above, the cooling tower 2 can be installed not only in the square cooling tower (FIGS. 1, 4 and 6) but also in the round cooling tower (FIG. 7).

  In the above wind turbine generator, a single cooling tower is shown as the cooling tower. However, if the cooling fans 1 of the cooling tower are installed side by side, generators are installed as many as the number of cooling fans. As a result, a considerable amount of generated power can be obtained.

  In the wind turbine generator described above, the vertical frames 4a of the wind turbine mounting frame 4 are the four corners of the cooling tower 2 (four directions of the position of the foundation 3), but the round cooling tower can be installed in three directions. By dispersing the pillars from the direction, the foundation of the cooling tower itself can be used as it is, so there is no need to make a new strong foundation.

  In the wind power generator according to the present embodiment, even in the foundation work of the foundation 3, it can be installed without affecting the frame of the building.

  In the wind turbine generator according to the present embodiment, in the case of a new installation, the installation can be performed in the same arrangement as the current situation only by installing a leg that can withstand the load of the windmill on the cooling tower 2 itself.

  In the wind power generator according to the present embodiment, the repair and maintenance of normal wind power generation is carried out at a considerable height by installing a scaffold for high-altitude work each time. Therefore, since the cooling tower 2 can be used, repair and maintenance are possible without installing a scaffold. Therefore, it is possible to save the cost and time for installing the scaffold.

  In the wind power generator according to the present embodiment, since it is not necessary to perform the work at a high place again because of the structure as described above, it can be easily inspected as one of daily inspections.

  The wind turbine generator according to the present embodiment can be used to the maximum extent by installing it on the rooftop of the city center.

  Wind power generation must be installed in a place where normal wind blows strongly, but this embodiment has the advantage that the rooftop of a building in the city is always at a high place and the advantage of a place with a strong natural wind can be utilized. Have.

  When the cooling tower is large, several to a dozen or more units are installed in parallel, but this wind power generator can also be installed in the number of units and the number of exhaust ports.

  Then, operation | movement of the wind power generator which concerns on this Embodiment is demonstrated.

  During operation of the cooling tower 2, the horizontal axis wind turbines 6 and 6a receive the exhaust air 7 from the cooling fan 1 and rotate to generate power.

  Even when the cooling tower 2 is stopped, if the natural wind 8 is present, the vertical axis wind turbine 5 receives the cross wind from all directions and rotates to generate power.

  Even when the cooling tower 2 is stopped other than during cooling, the natural wind 8 from all directions is received by the vertical axis wind turbine 5 to rotate and generate electric power.

  Even when the cooling tower 2 is completely stopped during heating, power can be generated by the natural wind 8.

  When the summer temperature rises and there is no wind during the cooling season, the operation of the cooling fan 1 is continued. Therefore, the exhaust air 7 is also generated continuously, so that the rotation time of the horizontal axis wind turbines 6 and 6a becomes longer, and the power generation Capacity and power generation time are maximized. It is possible to generate electricity without wind during cooling, and it is possible to generate electricity with the natural wind 8 even when the cooling tower 2 is stopped during heating.

  The wind power generator according to the present embodiment has solved the disadvantages of the conventional wind power generation that does not generate power when no wind is generated by receiving the wind of the cooling tower 2 that has been thrown away when there is no wind.

  Installation of wind power generation facilities in the middle of the city center is very difficult due to space limitations, but if wind power generation facilities are installed on the rooftop of a building unique to the city center, there are many places where it can be installed.

  Wind power generation has little wind on flat ground, so it is necessary to set up the pillars (vertical wings) 10 upwards as much as possible, but because the roof of the building, the wind received by the blades (vertical wings) 10 is high. More effective than standing.

  By rotating the horizontal axis wind turbines 6 and 6 a, an air flow in the upward direction of the horizontal axis wind turbines 6 and 6 a is generated and becomes a shield in the direction of the wind on the cooling fan 1, and the blades (vertical blades) 10 of the vertical axis wind turbine 5 However, ascending air current above the horizontal axis wind turbines 6 and 6a functions as an exhaust pipe rather than a shield, and prevents a short circuit of the exhaust air, thereby increasing efficiency and further synergistic effects.

  Since this effect and the blades (vertical blades) 10 of the vertical axis windmill 5 further suppress the airflow dispersion on the cooling fan 1 and collect the airflow, the rotation of the windmill can be promoted.

  When the wind turbine does not rotate for some reason (failure, etc.), the exhaust wind 7 of the cooling tower 2 does not become a resistance even if it hits the blades (vertical blades) 10 of the vertical axis wind turbine 5, so it is given to the capacity of the cooling tower 2 There is no effect.

  In addition, when the natural wind 8 has an air volume necessary for generating electricity, the effect is further enhanced. This is because the wind power generation by the vertical axis wind turbine 5 exerts its effect when the natural wind is large in summer, but the updraft generated by the wind power generation by the horizontal axis wind turbines 6 and 6a helps the exhaust air of the cooling tower 2 at that time. It plays a role and can raise the efficiency of the cooling tower 2. This has the advantage that the power consumption of the cooling tower 2 itself can be suppressed.

  When the natural wind is strong, the connecting portion between the generator and the wind turbine is disconnected, and the fan on the cooling tower side is directly rotated by directly connecting to the fan shaft of the cooling tower, so that the power generation loss can be eliminated. Since the rotational speed of 200 rpm is different from the rotational speed of 400 rpm when the capacity of the cooling tower is 100%, the load when rotating with wind power is limited to a low load.

  Hereinafter, the operations of the vertical axis wind turbine 5 and the horizontal axis wind turbines 6 and 6a in the wind turbine generator according to the present embodiment will be described in summer and winter.

Summer = When the cooling tower is in operation:
When there is no natural wind, the horizontal axis wind turbines 6 and 6a are rotated to generate electricity. In this case, the vertical axis wind turbine 5 is driven and rotated as a load, but the exhaust air 7 from the cooling tower passes straight upward, so that no counter-torque is generated, and it plays a role as an exhaust pipe.

  When there is a natural wind, the vertical axis wind turbine 5 and the horizontal axis wind turbines 6 and 6a are rotated to generate power.

Winter = When the cooling tower is stopped:
When there is no natural wind, the vertical axis wind turbine 5 and the horizontal axis wind turbines 6 and 6a are not rotated and no power is generated.

  When there is a natural wind, the vertical axis wind turbine 5 is rotated to generate power. In this case, the horizontal axis wind turbines 6 and 6a are driven and rotated as loads, but the rotation moment of the horizontal axis wind turbines 6 and 6a is small, so that the rotation of the vertical axis wind turbine 5 is not hindered.

  As is clear from the above description, according to the present embodiment, the horizontal axis wind turbine is rotated by receiving the exhaust air from the cooling tower when the cooling tower is in operation, and the natural wind is received vertically when the cooling tower is stopped. By rotating the axial windmill and driving the generator, full power generation is possible, and constant power generation can be achieved. That is, the greatest advantage of the hybrid wind turbine generator of the present embodiment is a natural energy one wind power generation system that uses a cooling tower installed on the roof of a building such as a city center or a downtown area. With this operation, almost full power generation is possible, and power generation can be expected at all times. Even when the cooling tower 2 is stopped, it is possible to generate power by receiving natural wind.

  Furthermore, according to the present embodiment, the vertical axis wind turbine and the generator are installed on the roof, so that it is safe for ordinary people to approach.

  In addition, according to the present embodiment, the vertical axis wind turbine and the generator do not need a foundation, and can be installed in the cooling tower or the like, so that the construction cost is low.

  Moreover, according to this Embodiment, since a vertical axis windmill and a generator are easy to receive a natural wind by rooftop installation, power generation efficiency is good.

  Furthermore, according to the present embodiment, the vertical axis wind turbine and the generator can be installed on the rooftop of a building in the city center, and the installation area is greatly expanded.

  In addition, according to the present embodiment, the vertical axis wind turbine can be installed in the existing cooling tower, and it is not necessary to change the structure of the cooling tower again.

  Further, according to the present embodiment, the vertical axis wind turbine does not use large blades, and the system itself is inexpensive.

  In addition, according to the present embodiment, the wind at the time of cooling tower operation can be used, and natural wind can be used even when the cooling tower is stopped (in winter). .

  Furthermore, according to the present embodiment, it is possible to evacuate to the rooftop of a building at the time of a disaster. However, since the hybrid wind power generator is effectively generated even in such a case, it can be used as a power source. Demonstrate.

  In addition, the power receiving equipment for ordinary buildings and private power generation equipment for emergencies are installed in a considerable amount underground. Major disasters that hit buildings in the city center include tsunami disasters caused by earthquakes and flood damage caused by typhoons. When a large tsunami and flooding occur, the electrical relationship will be greatly affected, and it will take time to recover. If electricity becomes unusable after being submerged in the basement, it may take a considerable number of days (units of several months) for restoration depending on the scale of the earthquake and flooding. Considering the restoration of power transmission from power companies and the restoration of power receiving equipment, electricity cannot be used regardless of which one is missing.

  Being able to supply the minimum electricity required in such a case with the wind turbine generator of the present embodiment is a great advantage. For regular use, it can be used for charging electric vehicles, lighting in buildings, etc. In the event of an emergency, it is necessary to charge personal computers and mobile phones with electricity generated by natural wind, and to supply power to lighting equipment in an emergency.
