Description

  The present invention relates to a hybrid power generation device that generates power using sunlight and a water stream that are clean and renewable energy.

There are many hybrid power generation devices that generate power using a wind turbine (wind power generation device) and sunlight (solar power generation device), as shown in the patent document described later.
Most of the devices that use wind turbines have blades of a propeller type, and are installed on a high tower to obtain a large amount of electric power. The yaw device and the like are required, and with the demand to generate a large amount of electric power, the device is inevitably large (large scale). When this configuration is combined with solar power generation, most of the above patent documents include a configuration in which a solar panel is provided on the wall surface of the tall tower to increase the amount of power generation.

  Conventional renewable energy power generators generally have a problem of how many kW is generated per unit. In other words, all of the small-scale power generators described in the prior art documents, which will be described later, all display the performance of the device only in kW unit.

  However, the windmill is stable to some extent if it is always blown, but in most cases it is always stable, there are few places with the same amount of wind, and there are few places where wind blows stably throughout the year. (The wind is a movement of large and small vortices, so it changes remarkably depending on the seconds, minutes, hours, days, weeks, months, and seasons). In particular, there is a problem in that the fluctuation of the wind due to the latter season leads directly to the intensity of the fluctuation of electric power and is not stable. Moreover, we cannot expect to use a windmill in a place where there is no wind.

  On the other hand, in the solar power generation device, the amount of solar radiation during the day is determined by the amount of solar radiation time, and the amount of power that can be generated also changes depending on the weather. Furthermore, in some seasons, there is a difference in power generation due to the difference in the amount of solar radiation.

  With a power source that fluctuates greatly as described above, it makes no sense to consider how much power generation can be obtained in an instant, and how much kWh can be stably obtained throughout the year becomes a problem, and it is possible to cope with it. There has been a demand for an improved power generator.

  The present invention has been made in view of the above problems, and an object thereof is to provide a hybrid power generation device capable of generating electric power stably throughout the year.

  First, the technical background leading to the present invention will be described. The clean and renewable energy (natural energy, sustainable energy) changes significantly in terms of wind conditions, water conditions, and the amount of solar radiation (sunlight) throughout the seconds, minutes, days, days, months, and years. It is not easy to stabilize such clean and renewable energy (natural energy, sustainable energy) as an independent power source. Therefore, in order to build a sustainable society in the future, it is essential to stably convert hydropower, wind power, and sunlight into electric energy (independent power source) for use and application. Furthermore, as a premise of the creation of the present invention, paying attention to how stably such an independent power source can be secured in a place where almost no wind blows, and the present invention is based on the above technical background. Was devised.

Therefore, the hybrid power generator according to the present invention is
On the place where there is a flow of water, a vertical axis type water flow power generation device is installed to generate power by submerging the blade part in the water flow,
In addition to that, a basic feature is that a solar power generation device that generates power with a solar panel is provided.

  According to the above configuration, of the configuration of the vertical axis type hydroelectric generator, where the water flow is present, the blade constituting the main body portion (vertical rotation axis and blade) is submerged in the water stream, and the blade is surrounded by the surrounding area. Power is generated by the vertical axis type water flow power generation device by rotating around a vertical rotation axis attached to the.

  The flow of water such as rivers fluctuates throughout the four seasons, but the fluctuation range is generally not large. Even if there is a fluctuation, unlike a solar power generator that has a fluctuation range between day and night, there is no big difference in the fluctuation range of the water flow at day and night, and the fluctuation range of the weather due to rain, cloudy, sunny, etc. Smaller than solar power generators. On the other hand, if there are fluctuations in the season when there is a large amount of rainfall and the season when there is little rainfall and the sunlight is often shining, the vertical axis type water flow power generator and the solar power generator compensate for the fluctuation in the amount of power generation and Even if there is a change, it will lead to stabilization of the amount of power generation (kWh) throughout the year.

  In addition, there is a stable flow of water in a waterway (waterflow) such as an irrigation canal, which plays an important role as a stabilized power source. That is, year-round electric power can be stably obtained in kWh. By providing a photovoltaic power generation device having a large fluctuation range of power generation throughout the year, the power generation of these power generation devices complement each other synergistically, and a stable power generation amount (kWh) can be obtained throughout the year.

  Here, the above-mentioned water current power generator is configured to have a vertical axis type because power can be generated by arranging the blades constituting the main body portion (vertical rotation axis and blades) in water, and generating power by building a dam or the like. This is because, unlike a large hydroelectric power plant, it can be easily installed in suitable places (rivers and waterways) so that a stable power source can be obtained immediately.

  The solar power generation device according to the present invention is provided on the water current power generation device in a place where the installation is low, such as the Ogasawara Islands in Japan or Yonaguni Island in Okinawa, where the solar power is low. This is because when the light is received above, the solar power generation device has the highest power generation efficiency and the amount of power generated per day increases. In addition, the installation method is such that the sunlight can be received at an angle that can receive more sunlight during the day depending on the latitude of the installation location (the amount of received sunlight is greater) than when installed vertically. It is desirable that a panel be provided.

  The water current power generator of the present invention has a built-in device that integrates a water current turbine, a generator, a power storage device, a control configuration, an inverter, an outlet for output, etc., which are necessary for water current power generation, or of those configurations. A part (for example, a charger) may be installed outside this configuration. In addition, a solar power generation device is also built in, for example, on the lower surface or underneath of a solar panel (a device that integrates a power storage device, a control structure, an inverter, an outlet for output, etc.), or a part of these structures. (For example, a charger, etc.) may be installed outside this configuration.

  Furthermore, the blades that make up the main body (vertical rotation shaft and blades) of the vertical axis type hydroelectric generator can move up and down. If necessary, they can be placed in water to generate electricity, and can also be pulled out of the water and safely saved. It is desirable to be able to. The device may be assembled without being configured to be able to move up and down from the beginning on the assumption that it will be submerged in water, but the momentum of the water is too intense, the rotating shaft part that generates power is burned out, or the flow of water flows with the momentum of the water. In order to prevent the object from hitting the blade and breaking it, and to prevent the device from functioning as a power generator due to flooding of the river or overflow of water from the waterway, the above configuration can be used. desirable.

  In addition, a plurality of hybrid power generation devices according to the present invention may be provided at regular intervals along a place where water flows (for example, a water channel). This is because the amount of power generated by each hybrid power generation device increases, for example, even in a narrow area in a certain area, as the number of power generations increases. However, when the blade is rotated in the flow of water and a certain interval is not provided downstream thereof, the flow is disturbed and the power generation efficiency of the power generation device downstream is reduced. Therefore, it is necessary to install these hybrid power generation devices according to the present invention at regular intervals (which will be described in detail in later-described embodiments).

  According to the hybrid power generation device of the present invention, the vertical axis type water current power generation device contributes to a small fluctuation range of power generation throughout the year. Therefore, the synergistic effect of the combination of the two power generation devices causes the fluctuation range of power generation throughout the year. Can be made small, and an excellent effect that it can be leveled at kWh can be obtained. In particular, there is a special note on reducing the fluctuation range of power generation of vertical axis type hydroelectric generators throughout the year.Since it functions as a base load power source in this hybrid generator, the above effect is remarkable in remote areas. To be demonstrated.

It is explanatory drawing which shows the cross-sectional structure containing the water channel which shows the state which looked at the structure of said FIG. 9 from the direction according to FIG.

  Embodiments of the present invention will be described below with reference to the illustrated examples.

  As shown in FIGS. 1 to 3, a hybrid power generator according to an embodiment of the present invention is a straight-blade vertical axis type fixed type that generates power by immersing the blade 1a portion in the water flow on one water channel W. A pitch water current power generation device 1 is provided, and a solar power generation device 2 in which a solar panel 2a is horizontally installed facing upward is provided thereon.

  In the configuration of the above-described embodiment, in the water passage W, the integrated blade 1a that constitutes the main body portion (vertical rotation shaft and blade) of the straight-blade vertical axis type fixed pitch hydroelectric generator 1 is submerged in the water stream, and the blade 1a is Power is generated by the straight-blade vertical axis type fixed pitch water current power generation apparatus 1 by rotating around a vertical rotation axis attached to the periphery.

  The integrated straight-blade vertical axis type blade is used for the water current power generation device 1 described above. Power can be generated by arranging the straight-blade vertical axis type blade constituting the main body in water, and a dam or the like is constructed to generate power. This is because, unlike a large hydroelectric power plant, it can be easily installed in suitable places (rivers and waterways) so that a stable power source can be obtained immediately.

  Further, the straight-flow blade vertical axis type fixed pitch is used for the water current power generation device 1 because the angle of attack of the straight-blade, each mounting angle of the straight-blade, the supporting blade and the shaft, and the aerodynamic center of the straight-blade are optimal. If fixed, all can be fixed pitch. These have been clarified by theory and experiment. Especially, limited to "fixed pitch" is to strengthen structural strength by manufacturing and manufacturing "integral type" of blade, aerodynamics. This is because it contributes to performance increase, unitization, cost reduction, and the like.

  The flow of water such as rivers fluctuates throughout the four seasons, but the fluctuation range is generally not large. Even if there is a fluctuation, unlike a solar power generation device that has a fluctuation range between day and night, there is no great difference in the fluctuation range of the water flow between day and night. On the other hand, if there is a change in the season when the amount of rainfall is large and the season when the amount of rainfall is small and the sunlight is often shining, the vertical axis type water flow power generation device 1 and the solar power generation device 2 compensate for the change in the amount of power generation. Even if there is a seasonal change, it will lead to the stabilization of the power generation amount (kWh) throughout the year.

  In addition, there is a stable flow of water in a waterway (waterflow) such as an irrigation canal, which plays an important role as a stabilized power source. That is, year-round electric power can be stably obtained in kWh. By providing the solar power generation device 2 with a large fluctuation range of power generation throughout the day and season, the power generation of these power generation devices complement each other synergistically, and a stable power generation amount (kWh) can be obtained throughout the year. It will be.

  Further, as shown in the drawing, the blade 1a constituting the main body portion (vertical rotation shaft and blade) of the straight blade vertical axis type fixed pitch hydroelectric generator 1 is vertically movable and, if necessary, is placed in water. It generates electricity and can also be pulled out of the water for safe evacuation. The device may be assembled without being configured to be able to move up and down from the beginning on the assumption that it will be submerged in water, but the momentum of the water is too intense, the rotating shaft part that generates power is burned out, or the flow of water flows with the momentum of the water. The above configuration is also used in order to prevent an object from hitting the blade and breaking it, and to prevent the device from functioning as a power generator due to flooding of a river or overflow of water from a waterway.

  The above solar power generation device 2 is provided on the one where the installation location is a place where the latitude is low, such as the Ogasawara Islands in Japan or Yonaguni Island in Okinawa, where the sunlight is received above. However, this is because the solar power generation device 2 has the highest power generation efficiency and the amount of power generation per day increases. Therefore, as for the way of installation, as shown in FIGS. 1 to 3, the solar panel 2a is installed horizontally facing upward.

  Further, as shown in FIGS. 4 and 5, the hybrid power generator according to the present embodiment is provided in plural along the water passage W at regular intervals. This is because the amount of power generated by each hybrid power generation device increases, for example, even in a narrow area in a certain area, as the number of power generations increases. However, when the blade is rotated in the flow of water and a certain interval is not provided downstream thereof, the flow is disturbed and the power generation efficiency of the power generation device downstream is reduced. More specifically, by separating the blade 1a by 10 times or more the diameter of the water turbine configured by rotating, the blade 1a located downstream of the blade 1a is not affected by the eddy current generated in the upstream blade 1a, In order to return to the normal flow of water, the distance is set to be about 10 times the diameter of the water turbine constituted by the rotation of the blade 1a.

  Each power generation device in this embodiment may have a built-in device, which is necessary for water current power generation, in which each blade configuration, generator, condenser, control configuration, inverter, output outlet, etc. are integrated. In the configuration, a part of these configurations (for example, a charger) is installed outside this configuration. In addition, the solar power generation device 2 may be built in (a device that integrates a power storage device, a control configuration, an inverter, an outlet for output, etc.) on the lower surface thereof on which the solar panel 2a is installed, or may have a configuration of those components. A part (for example, a charger) may be installed outside this configuration.

  According to the hybrid power generator of the present embodiment, the fluctuation range of power generation throughout the year can be made small by the synergistic effect of the combination of the two power generators, and the leveling can be performed by kWh. In particular, there is a special note on reducing the fluctuation range of power generation of the vertical axis type hydroelectric generator 1 throughout the year, and since it functions as a base load power source in this hybrid generator, the above-mentioned effect is remarkable in remote areas. To be demonstrated.

  Next, another embodiment of the present invention will be described.

  6 to 8 show a hybrid power generator according to a second embodiment of the present invention. That is, in the configuration of this embodiment, as in the case of the first embodiment, the straight-blade vertical axis type fixed-pitch water flow power generation device 1 for generating electricity by submerging the blade 1a portion in the water flow is provided on the one water passage W. Further, a solar power generation device 2 provided with solar panels 1a on the four sides and on the upper surface (which are installed horizontally facing the upper side) is provided above it.

  In the configuration of the above-described embodiment, the configuration of the straight-blade vertical axis type fixed pitch hydroelectric generator 1 is the same as that of the first embodiment, and thus detailed description thereof will be omitted. However, also in this configuration, in the water passage W, the integrated blade 1a that constitutes the main body portion (vertical rotation shaft and blade) of the straight blade vertical axis type fixed pitch hydroelectric generator 1 is submerged in the water stream, and the blade 1a It is important for the straight blade vertical axis type fixed pitch water flow power generation apparatus 1 to generate electricity by rotating around a vertical rotation axis attached to the circumference.

  Also in the configuration of this embodiment, the solar power generation device 2 is provided on the water flow power generation device 1 to further generate power. The method of installing the solar power generation device 2 is different from that of the first embodiment.

  As described above, the solar power generation device 2 is fixed above the water current power generation device 1 by providing the solar panels 2a facing the four directions and the upper surface (which is installed horizontally facing upward). There is. The solar panel 2a covers everything except the lower surface where sunlight cannot be seen.

  With such a method of installation, the present solar power generation device 2 can obtain the maximum amount of power generation as long as sunlight can be received even when there are fluctuations in daytime and seasonal fluctuations in sunshine hours. . In particular, in places such as the Ogasawara Islands in Japan and Yonaguni Island in Okinawa, where the latitude is low, sunlight can be received on the water current power generation device 1 and thus sunlight can be received on all but the bottom surface. Since the solar panel 2a is installed, the solar power generation device 2 has the highest power generation efficiency and the amount of power generated per day increases.

  Even in the configuration of this embodiment, the water channel W led from a river or the like has a fluctuation range throughout the four seasons, but the fluctuation range is generally not large. Even if there is a fluctuation, unlike the solar power generation device 2 which has a fluctuation range of day and night and a fluctuation range depending on the season, there is no large difference in the fluctuation range of the water flow at day and night, and the fluctuation range of the weather due to rain, cloudy weather, sunny weather, etc. The water flow power generation device 1 is smaller than the solar power generation device 2. In particular, there is a special mention in reducing the fluctuation range of power generation of the vertical axis type hydroelectric generator 1 throughout the year. Since it functions as a base load power source in this hybrid generator, a straight-blade vertical axis fixed pitch hydroelectric generator. 1 and the solar power generation device 2 compensate for the fluctuation of the power generation amount, and even if there is a seasonal change, the power generation amount (kWh) is stabilized throughout the year.

  Further, as shown in FIGS. 9 and 10, a plurality of hybrid power generators according to the present embodiment are provided along the water passage W at regular intervals. This is because the amount of power generated by each hybrid power generation device increases, for example, even in a narrow area in a certain area, as the number of power generations increases. However, when the blade 1a is rotated in the flow of water, the flow will be disturbed unless a certain interval is placed downstream thereof, and the power generation efficiency of the power generator downstream will be reduced. More specifically, by separating the blade 1a by 10 times or more the diameter of the water turbine configured by rotating, the blade 1a located downstream of the blade 1a is not affected by the eddy current generated in the upstream blade 1a, In order to return to the normal flow of water, the distance is set to be about 10 times the diameter of the water turbine constituted by the rotation of the blade 1a.

  Each power generation device in this embodiment may have a built-in device, which is necessary for water current power generation, that integrates a blade configuration, a generator, a storage battery, a control configuration, an inverter, an output outlet, and the like. Then, a part of those components (for example, a charger) is installed outside this component. In addition, the solar power generation device 2 may be built in (a device that integrates a power storage device, a control configuration, an inverter, an outlet for output, etc.) on the lower surface thereof on which the solar panel 2a is installed, or may have a configuration of those components. A part (for example, a charger) may be installed outside this configuration.

  The hybrid power generation device according to the present embodiment includes the solar power generation device 2 having a larger fluctuation range of power generation than the water current power generation device 1. However, due to the synergistic effect of the combination of these two power generation devices, power generation throughout the year It is possible to reduce the fluctuation range of s and to equalize with kWh. In particular, in the water channel W, there is a stable flow of water, and the straight-blade vertical axis type fixed-pitch water flow power generator 1 generates a stable power supply (base load power supply) in terms of kWh in terms of annual electric power. It will be stable. In addition, since the solar power generation device 2 is provided on the water current power generation device 1 and the solar panel 2a that can receive the sunlight is installed on all of the surfaces except the lower surface, the solar power generation device 2 is also installed. The device 2 has the largest amount of power generation.

  The hybrid power generator of the present invention is not limited to the above-mentioned embodiments, and it goes without saying that various modifications can be made without departing from the gist of the present invention.

  Among the devices that generate renewable energy, the hybrid power generation device of the present invention is a local production for local consumption type power generation device based on the fact that damage was revealed by typhoons No. 15 and No. 19 in 2019. Not only that, it can be used all over the world, especially in low latitude areas.
