Summary of the Invention

Problems to be Solved by the Invention

[0004] However, most of the power generation devices of this kind known conventionally are only for generating electricity. In facilities that require electricity, such as homes and companies, various economic activities are carried out using various facilities, so a composite system having various functions in addition to power generation is required.

[0005] The present invention has been made in view of the above circumstances, and an object thereof is to provide a composite power generation system having a plurality of functions, particularly a power generation and water supply system having a water supply function together with a power generation function.

Means for Solving the Problems

[0006] The present invention provides a water supply system comprising: a tubular support column inserted into a well and erected from the bottom of the well; a photovoltaic power generation device provided at the top of the support column; a conduit disposed inside the support column and extending upward from its lower end, which is immersed in the groundwater in the well, to the photovoltaic power generation device; and a pump for sending the groundwater in the well to the photovoltaic power generation device through the conduit.

[0007] According to the above configuration of the present invention, since it is equipped with both a power generation function and a water supply function, it becomes possible to realize economic activities that utilize the supply water and solar heat in a complex and multifaceted manner.

[0008] Furthermore, it is preferable that the power generation and water supply system with the above configuration be further equipped with a wind power generation device at the top of the support column. This makes it possible to generate electricity not only from solar power but also from wind power, significantly increasing the amount of electricity generated. In addition, this also makes it possible to significantly reduce the amount of electricity consumed using existing commercial power sources.

[0009] Furthermore, it is preferable that the power generation and water supply system with the above configuration be further equipped with a distribution pipe that branches off from the conduit and supplies the groundwater sent through the conduit to the building. This allows for the efficient use of groundwater for domestic use or business use (industrial water) in the building.

[0010] Furthermore, in the above configuration, it is preferable to further include a purification device that supplies water to the indoors and purifies the water used indoors, a supply pipe installed inside the support column that supplies the water purified by the purification device to the solar power generation device, and a spraying device installed at the top of the supply pipe that sprays the water supplied through the supply pipe toward the solar power generation device. With this configuration, not only can the groundwater used indoors be purified and the solar power generation device be cleaned with the purified water, but birds, insects, etc. that approach the solar power generation device and cause harm can be exterminated by spraying water, and wear and tear on each piece of equipment can be prevented.

[0011] Furthermore, the power generation and water supply system with the above configuration preferably includes a coil pipe that is immersed in the groundwater in the well and through which the air in the well can circulate, and a cooling and blowing device that pumps the air in the coil pipe, which has been cooled by the groundwater, into the building. This allows the air cooled or humidified using groundwater to be used indoors, for example, in air conditioning equipment.

[0012] Furthermore, in the above configuration, it is preferable that the wind power generation device has blades fixed to a support column and rotatable by wind power, and a generator that converts the rotational motion of the blades into electrical energy, and the solar power generation device has at least one device body supported by a support column and having solar panels attached to its surface that convert sunlight into electrical energy. This allows the wind power generation device and the solar power generation device to be functionally installed on a support column extending from a well.

[0013] Furthermore, in the above configuration, it is preferable that the main body of the photovoltaic power generation device includes a pair of spherical first and second device bodies positioned above and below the wind power generation device, covering the wind power generation device from above and below, and a third device body that surrounds the wind power generation device from the side around its entire circumference. With this configuration, the main body of the photovoltaic power generation device can be used as a housing that surrounds the wind power generation device and protects it from the external environment.

[0014] Furthermore, in the above configuration, it is preferable that the third device body is composed of a plurality of rotatable wind direction guide plates for guiding wind toward the wind power generation device, and that the plurality of wind direction guide plates have solar panels on both sides and cooperate with each other to form a cylindrical shape, thereby being rotatable between a closed position that completely closes the inner space where the wind power generation device is located from the sides all around, and an open position that opens the space at least partially from the sides, allowing wind to be guided toward the wind power generation device. With this, the third device body of the solar power generation device can be given a combination of functions, namely, a wind direction guide function toward the wind power generation device (with a wind absorption effect) (in the open position) and a protective function that protects the wind power generation device from strong winds such as typhoons (in the closed position). In addition, since the wind direction guide plates have solar panels on both sides, the third device body can be given a solar power generation function in both the open position and the closed position.

[0015] Furthermore, in the above configuration, it is preferable that the first and second device bodies are movable vertically, and that when the third device body is in a closed position, they move toward the third device body to cover the space from above and below, thereby working together with the third device body to completely close the space from the external environment and create a sealed space. This allows the wind power generation device to be completely isolated and protected from the external environment by the solar power generation device during strong winds such as typhoons. It is preferable that such a typhoon protection function is operated by a wind force detection function and an electromagnetic automatic opening and closing function.

[0016] Furthermore, in the above configuration, it is preferable that the main body of the photovoltaic power generation device further includes a fourth device body that defines a storage space for storing groundwater supplied through a conduit, and that this fourth device body generates hot water by heating the groundwater stored in the storage space with sunlight. This allows for the combined and effective utilization of solar heat and groundwater.

[0017] In addition, it is preferable that the power generation and water supply system with the above configuration further includes a hot water supply pipe for supplying hot water stored in the storage space and heated by sunlight indoors. According to this, groundwater can be heated and used as hot water in indoor hot water supply facilities (for example, hot baths and air conditioning facilities, etc.). In addition, the fourth device main body may heat the air stored inside by sunlight. In that case, it is preferable to further provide a blower pipe for supplying the heated air in the fourth device main body indoors. Such warm air is introduced into, for example, air conditioning facilities.

Modes for Carrying Out the Invention

[0020] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Figures 1 and 2 schematically show a power generation water supply system 1 (for example, at a height of 7 m above ground level) according to one embodiment of the present invention. In this case, Figure 1 is a schematic cross-sectional view showing the schematic configuration of the lower part of the power generation water supply system 1, where Figure 1(a) shows the schematic configuration near the ground level, Figure 1(b) shows the schematic configuration near the middle of the well, and Figure 1(c) shows the schematic configuration near the bottom of the well. Figure 2 is a schematic configuration diagram of the upper part of the power generation water supply system 1. As shown in these figures, the power generation water supply system 1 of this embodiment includes a tubular support column 10 (for example, 8 cm in diameter) inserted into a well W (for example, 16 cm in diameter, 7 m deep) dug in the ground 50 and supported at the well formation site (support part is not shown), or erected from the bottom Wa of the well W. In addition, as shown in Figure 2, a photovoltaic power generation device 20 is provided on the upper part of this support column 10. The photovoltaic power generation device 20 is supported by a support column 10 and has at least one device body on which a solar panel 20a that converts sunlight into electrical energy is attached to the surface. In particular, in this embodiment, the photovoltaic power generation device 20 comprises four device bodies 20A, 20B, 20C, and 20D.

[0021] Furthermore, a conduit 15 is installed inside the support column 10, and this conduit 15 extends upward from its lower end, which is immersed in the groundwater in the well W, to the solar power generation device 20 (see also Figure 3). A pump P (see Figure 1) is inserted into the conduit 15 to send the groundwater in the well W to the solar power generation device 20 through the conduit 15, and the water supply device 18 is formed by this pump P and the conduit 15.

[0022] Furthermore, the power generation and water supply system 1 is further equipped with a wind power generation device 30 (see Figure 2) on top of the support column 10. This wind power generation device 30 is fixed to the support column 10 and has, for example, three blades 32 that can be rotated by wind, and a generator 33 that converts the rotational motion of the rotation axis 32a of the blades 32 into electrical energy.

[0023] The aforementioned main body of the solar power generation device 20 includes a pair of spherical first and second main body structures 20A and 20B (for example, both 5 m high) positioned above and below the wind power generation device 30, covering the wind power generation device 30 from above and below, and a third main body structure 20C (for example, 9 m high) that surrounds the wind power generation device 30 from the side around its entire circumference.

[0024] The third device body 20C, as shown in Figures 4 and 5, is composed of a plurality (six in this embodiment) of rotatable wind direction guide plates 20Ca for guiding the wind 35 toward the wind power generation device 30. Each wind direction guide plate 20Ca has a solar panel 20a on both sides. These plurality of wind direction guide plates 20Ca can be rotated by power (operation control device not shown) around a pivot axis 37 between a closed position (position of dashed line in Figure 4) where they cooperate to form a cylindrical shape, completely closing the inner space S in which the wind power generation device 30 is located from the sides, and an open position (position of solid line in Figures 4 and 5) where the space S is at least partially opened from the sides, allowing the wind 35 to be guided toward the wind power generation device 30. According to this, the third device body 20C of the photovoltaic power generation device 20 can perform a wind direction guidance function to the wind power generation device 30 by wind direction guide plates 20Ca in the open position, and can perform a protective function to protect the wind power generation device 30 from strong winds such as typhoons in the closed position. Furthermore, since the wind direction guide plates 20Ca have solar panels 20a on both sides thereof, the third device body 20C can be equipped with a photovoltaic power generation function in both the open and closed positions. The third device body 20C includes an inner cylindrical support 70 that surrounds the wind power generation device 30 from the outside to allow wind to flow into the inner space S where the wind power generation device 30 is located, and an outer cylindrical support 72 that surrounds the inner cylindrical support 70 from the outside to allow wind to flow into the inner space S where the wind power generation device 30 is located, and supports each of the six wind direction guide plates 20Ca so as to be rotatable around a pivot axis 37.

[0025] Furthermore, the closed position and the open position may be fixed by, for example, an electromagnet. Such a modified example is shown in Figure 6. As shown in the figure, in this modified example, the inner cylindrical support 70 is provided with an inner electromagnet 80A that can magnetically attract the tip of each wind direction guide plate 20Ca, and the outer cylindrical support 72 is also provided with an outer electromagnet 80B that can magnetically attract the tip of each wind direction guide plate 20Ca, corresponding to each wind direction guide plate 20Ca.

[0026] In this configuration, when the wind force of the external environment is below a predetermined threshold, a detection signal from a wind force sensor (not shown) detects this, causing the outer electromagnet 80B to become de-energized and the inner electromagnet 80A to become energized. The tip of each wind direction guide plate 20Ca is attracted to the corresponding inner electromagnet 80A of the inner cylindrical support 70 (and thus fixed to the inner cylindrical support 70), and each wind direction guide plate 20Ca is held in the open position. On the other hand, when the wind force of the external environment exceeds a predetermined threshold, a detection signal from a wind force sensor (not shown) that detects this occurs, causing the outer electromagnet 80B to become energized and the inner electromagnet 80A to become de-energized. As a result, each wind direction guide plate 20Ca detaches from its corresponding inner electromagnet 80A (and therefore from the inner cylindrical support 70), swings due to the wind (is blown by the wind), and its tip is attracted to the corresponding outer electromagnet 80B on the outer cylindrical support 72 (and therefore fixed to the outer cylindrical support 72), and each wind direction guide plate 20Ca is held in the closed position. The transition of the wind direction guide plate 20Ca from the closed position to the open position is based on the same principle.

[0027] Furthermore, in this embodiment, the first device body 20A and the second device body 20B are movable vertically (for example, movable 5 to 10 cm), and when the third device body 20C is in the closed position, they move toward the third device body 20C (to the position shown by the dashed line in Figure 2) to cover the space S from above and below, thereby working together with the third device body 20C to completely close the space S from the external environment and create a sealed space. With this, the wind power generation device 30 can be completely isolated and protected from the external environment by the solar power generation device 20 during strong winds such as typhoons.

[0028] The downward movement of the first device body 20A can be achieved, for example, by providing a water storage tank inside the first device body 20A, and when the wind force of the external environment exceeds a predetermined threshold, a detection signal from a wind force sensor (not shown) detects this and water is injected into the tank, causing the first device body 20A to move downward due to the weight of the water. In this case, the upward movement of the second device body 20B can be mechanically linked to the downward movement of the first device body 20A. On the other hand, when the wind force of the external environment falls below a predetermined threshold, a detection signal from a wind force sensor (not shown) detects this and the water is drained from the tank, and the lighter first device body 20A is raised to a predetermined position by a biasing force such as a spring. The second device body 20B also descends in mechanical linkage with this.

[0029] Furthermore, as shown in Figure 1, the power generation water supply system 1 of this embodiment also includes a distribution pipe 53 that branches off from the conduit 15 and supplies groundwater sent through the conduit 15 to the indoor area 90 via a pump P1. The groundwater supplied through the distribution pipe 53 in this way can be used as domestic water or industrial water for indoor facilities. The power generation water supply system 1 of this embodiment also includes a cooling air blower 63 that cools the air by utilizing the cold groundwater in the well W and blows the cooled air into the indoor area. This cooling air blower 63 has a coil pipe 13 that is immersed in the groundwater in the well W and through which the air in the well W can flow, and the air in the coil pipe 13 cooled by the groundwater is blown into the indoor area by a pump P2. The cooled air supplied through the coil pipe 13 in this way can be used indoors, for example, in air conditioning equipment (for example, it acts on indoor air conditioning (heating) through a hot air exchange pipe built into the solar water hot water conversion housing). The coiled pipe 13 is wound around and supported by a support pipe 11 that is positioned inside the well W to surround the support column 10, with one end of the coiled pipe opening above the water level inside the well W to allow air to flow in. The coiled pipe 13 can also be removed from inside the well W together with the support pipe 11 for purposes such as replacement or maintenance.

[0030] Furthermore, the main body of the aforementioned solar power generation device 20 further includes a fourth device body 20D (for example, 17m in height) which defines a storage space SS for storing groundwater supplied through the conduit 15, as shown in Figure 2. This fourth device body 20D is configured to generate hot water by heating the groundwater stored in the storage space SS with sunlight.

[0031] Furthermore, as shown in Figures 1 and 2, the power generation and water supply system 1 of this embodiment further includes a hot water supply pipe 27 for supplying hot water, which is stored in the storage space SS of the fourth device body 20D and heated by sunlight, to the interior of the building via a pump P3. This hot water supply pipe 27 is also installed inside the support column 10 together with the conduit 15 and extends in the vertical direction. The hot water supplied by this hot water supply pipe 27 can be used, for example, in indoor hot water supply equipment (such as bathtubs and showers). In addition to this hot water generation function, the fourth device body 20D also has a function of heating the air stored inside with sunlight. Specifically, an air layer is formed above the storage space SS inside the fourth device body 20D, and this air layer is heated by sunlight. In this case, the heated air inside the fourth device body 20D is supplied through the air supply pipe 69 to, for example, indoor air conditioning equipment and used for heating.

[0032] Furthermore, the power generation water supply system 1 of this embodiment further includes a purification device 92 that supplies water to the indoor 90 and purifies the water used in the indoor 90, a supply pipe 95 that is disposed inside the support column 10 and supplies the water purified by the purification device 92 to the solar power generation device 20 via a pump P4, and an injection device provided at the top of the supply pipe 95 for injecting the water supplied through the supply pipe 95 toward the solar power generation device 20. In particular, in this embodiment, such an injection device is configured as injection nozzles 17A and 17B that discharge a water jet 19 toward the spherical outer surface of the first and second device bodies 20A and 20B of the solar power generation device 20, as shown in Figure 2. Specifically, the first injection nozzle 17A that discharges a water jet 19 toward the first device body 20A from above is located above the first device body 20A and is provided at the upper end of the supply pipe 95. On the other hand, the second injection nozzle 17B, which discharges a jet 19 from below the second device body 20B, is located below the second device body 20B and is provided on the outer surface of the upper end of the fourth device body 20D. In addition to being able to clean the outer surfaces of the first and second device bodies 20A and 20B using the purified water described above, such an injection device can also be used to exterminate birds that approach the solar power generation device 20 and cause harm by spraying groundwater (performing bird control). Furthermore, in such extermination, a sensor for detecting birds may be provided, and groundwater may be sprayed from the injection device in response to signals from the sensor.

[0033] Furthermore, in addition to the above configuration, the power generation and water supply system 1 of this embodiment is also equipped with a lightning rod 81, a security camera 82, and a wireless transmitting and receiving antenna 83 on an extended support column 77 extending from the upper end of the support column 10. In addition, a wind power generation motor 98 for operating the wind power generation device 30 is installed inside the second device body 20B, and the various sensors mentioned above, including a wind sensor, are arranged inside the first device body 20A.

[0034] It should be noted that the present invention is not limited to the embodiments described above, and can be implemented in various ways without departing from the spirit of the invention. Furthermore, within the scope without departing from the spirit of the invention, some or all of the embodiments described above may be combined, or some of the components of one of the embodiments described above may be omitted.
