  However, in Patent Document 1, since the wind turbine cannot generate power unless the wind blows, it is necessary to install the wind turbine in a well-ventilated place, and the wind turbine unit is separately provided, so that the apparatus itself is enlarged. End up. In other words, in addition to the problem that the location and space of the installation conditions are restricted, the water flow generated by the self-contained energy by the corner energy is wasted only by using the agitation of lake purification, and is reused as energy. It has a problem that it cannot be used.

  The present invention has been made in order to solve the above-described problems, and one object of the present invention is to increase the degree of freedom of installation conditions and excel in the convenience of being portable and temporary. In addition, because it is possible to reuse the energy of the flow velocity of the water stream that was wasted, the water flow generator has a power generation function that can be used for securing auxiliary power in an emergency or using power from a commercial power source. And a water flow generation system having a power generation function.

  A water flow generating device having a power generation function according to a first aspect of the present invention includes a housing having a water intake port and a water supply port, a water flow generating unit equipped in the housing and equipped with a water flow impeller that generates a water flow. The power generation impeller mounted in the housing and equipped with the power generation impeller, and the power generation impeller is swiveled by the water flow generated by the water flow impeller of the water flow generation unit The power generation unit is configured to generate power.

  In the water flow generator having a power generation function according to the first aspect of the present invention, as described above, the power generation impeller is swiveled by the water flow generated by the water flow impeller of the water flow generation unit, thereby generating power. It is configured to generate electricity at the part. Thus, power generation can be performed if the casing portion of the water flow generation device is submerged without selecting a place where the water flow generation device is disposed, and thus the degree of freedom in installation conditions can be increased. In addition, the power generation impeller is swiveled by the water flow generated by the water flow impeller of the water flow generation unit so that the power generation unit generates power by the power generation unit so that the power generation unit can be configured to be integrated in series. Since the water flow generation unit and the power generation unit are both disposed in the water, unlike the conventional case where a wind turbine is provided on the water surface to drive the water flow generation unit, the apparatus can be reduced in size and weight. . As a result, a device excellent in portability can be temporarily installed without being fixedly installed (it can be moved and installed by human power without using heavy equipment).

  In the water flow generation device having a power generation function according to the first aspect, preferably, the power generation impeller has a function of rectifying the water flow generated by the water flow generation unit. If comprised in this way, it will generate electric power using the impeller which manages electric power generation which has a rectification function in parts, such as a current plate and a guide vane used for rectifying a water flow, as the impeller for electric power generation. Therefore, there is no need to provide a separate rectifying component (rectifying plate, guide vane, etc.), so the size and weight can be reduced. Can be reused effectively.

  In the water flow generating device having a power generation function according to the first aspect, preferably, the power generation unit is disposed on the side where the water flow generated by the water flow generation unit is fed so as to face the water flow generation unit. . If constituted in this way, for example, in consideration of the strong air blowing at the front of the fan that everyone has experienced and recognized and the low suction air at the back of the electric fan, the power generation unit corresponds to the back side of the electric fan. Unlike the case where the water flow generation unit is arranged on the suction flow side where the water is absorbed weakly, the water flow generation unit is arranged on the side of the strong water supply flow generated by the water flow generation unit corresponding to the front side of the electric fan. Thus, a water flow having a large flow velocity energy can be efficiently converted into electric energy.

  In the water flow generator having the power generation function according to the first aspect, preferably, the power generation impeller is provided on the water inlet side of the power generation unit. If comprised in this way, it will be equivalent to the front side of the said fan by suppressing that the water flow which flows in into this power generation impeller is inhibited by the main-body part (part containing a generator etc.) of this power generation part. The water flow generated by the water flow generating part and having a large momentum of flow velocity energy flows smoothly and directly into the power generation impeller without resistance, and further, the flow velocity energy generated by the water flow generation part is large. The water stream can be efficiently converted into electric energy without waste.

  In this case, preferably, the water flow impeller of the water flow generation unit is equipped on the water supply port side of the water flow generation unit, and the power generation unit is equipped with the power generation impeller so as to face the water flow impeller. . If comprised in this way, the member which becomes obstruction | occlusion of water flow, such as the main-body part (part containing a motor etc.) of this water flow generation part, is not arranged between this water flow impeller and this power generation impeller. Therefore, by suppressing the loss of the water flow, the water flow having a strong momentum generated by the water flow generation unit and having a large flow velocity energy can be smoothly and smoothly applied to the entire water absorption surface of the opposed impeller for power generation as described above. By directly flowing in, a water flow having a larger flow velocity energy than the above effect is efficiently converted into electric energy without waste, and the water flow impeller is located at a position in the housing sufficiently away from the water inlet. Because it is equipped, even in low-water-level installation where sufficient distance to the water surface cannot be taken, water is normally absorbed from the back of the water impeller while preventing air entrainment from the water surface. While preventing accidents such as aerated due to abnormal vibration or abnormal abrasion can perform stable water.

  In the water flow generating device having a power generation function according to the first aspect, preferably, the housing can be divided into a first portion in which the water flow generation unit is mounted and a second portion in which the power generation unit is mounted. It is configured. According to this configuration, the water flow generator having the optimum water flow generation capacity or the power generation section having the desired power generation capacity can be easily incorporated into the water flow generation apparatus having the power generation function with the optimum capacity according to the site conditions. Second, the power generation unit is mounted as necessary (when it is necessary to generate power) after arranging only the first part where the water flow generation unit is provided in the lake, etc. In addition to being able to generate power by connecting the part to the first part, even if the water flow generation unit or power generation unit fails, the first part or the second part to which the failed water flow generation unit or power generation unit is attached By exchanging only the part, it is possible to continue to operate the water flow generator having the power generation function.

  The water flow generator having a power generation function according to the first aspect preferably further includes a power storage unit that stores the power generated by the power generation unit. If configured in this way, the power generated by the power generation unit, for example, power supply for driving or lighting of the water flow generator as an auxiliary power source in an emergency, or power supply to peripheral devices at normal time, etc. It can be used appropriately according to the situation.

  In this case, preferably, based on an operation command from the operation unit, control of power supply from the power storage unit or the commercial power supply to the water flow generation unit, and control of power supply from the power storage unit to the peripheral device The control part which performs these is further provided. If comprised in this way, according to a situation by operation of this operation part by a user (based on a user's judgment), supply of electric power from the power storage part or the commercial power source to the water flow generation part appropriately In addition, as described above, by providing the control unit that controls the power supply from the power storage unit to the peripheral device, for example, securing an auxiliary power supply in an emergency, or the state where the power supply is stopped from the commercial power supply Therefore, the commercial power supply can be used for power saving by continuously supplying water from the power storage unit to the water flow generation unit via the control unit for a predetermined time.

  A water flow generation system having a power generation function according to a second aspect of the present invention includes a housing having a water intake port and a water supply port, a water flow generating unit equipped in the housing and equipped with a water flow impeller that generates a water flow. The power generation impeller mounted in the casing and equipped with the power generation impeller, and the power generation impeller is swiveled by the water flow generated by the water flow impeller of the water flow generation unit, A power storage unit configured to store the power generated by the power generation unit, and based on an operation command from the operation unit, control of power supply from the power storage unit or a commercial power source to the water flow generation unit, and the power storage And a control unit that controls power supply from the unit to the peripheral device.

  In the water flow generation system having the power generation function according to the second aspect of the present invention, as described above, the power generation impeller is swiveled by the water flow generated by the water flow impeller of the water flow generation unit, thereby generating power. It is configured to generate electricity at the part. As a result, power generation can be performed if the casing portion of the water flow generation device is submerged without selecting a place where the water flow generation device is disposed, and thus the degree of freedom in installation conditions can be increased. In addition, the power generation impeller is swiveled by the water flow generated by the water flow impeller of the water flow generation unit so that the power generation unit generates power by the power generation unit so that the power generation unit can be configured to be integrated in series. In addition, since the water flow generation unit and the power generation unit are both disposed in the water, it is possible to reduce the size and weight of the device, unlike the case where a wind turbine is provided on a conventional water surface to drive the water flow generation unit. It is possible to provide a water flow generation system having an excellent power generation function. Further, by providing a control unit that performs control of power supply from the power storage unit or the commercial power supply to the water flow generation unit and control of power supply from the power storage unit to peripheral devices, the user can According to the operation of the operation unit (based on the user's judgment), power supply from the power storage unit or the commercial power source to the water flow generation unit and power supply from the power storage unit to peripheral devices are appropriately performed according to the situation.

It is configured to generate a water flow by supplying electric power from the power storage unit 41 to the water flow generation unit 20 through the control unit 42 for a predetermined time to drive the water impeller 21 to turn. Yes. That is, the water flow generator 100 is configured such that the power stored in the power storage unit 41 can be used as auxiliary power. Thereby, suppression of use (power saving) of the commercial power source 51 is achieved.

  Moreover, the control part 42 supplies electric power to the water flow generation part 20 from the electrical storage part 41 via the control part 42 based on the operation command from the operation part 43 at the time of abnormality, such as at the time of a power failure, and the water impeller The water flow is generated by driving the swivel 21. That is, the water flow generator 100 can continue operation even during a power failure (emergency) such as a disaster.

  In addition, the control unit 42 operates the peripheral device 52 by supplying power from the power storage unit 41 to the peripheral device 52 in a normal time based on an operation command from the operation unit 43, and also causes an abnormality such as a disaster. In an emergency, it can be used as an auxiliary power source. The peripheral device 52 is, for example, a measuring device (such as a flow meter or a dissolved oxygen meter) that measures the water in the obstructive reservoir 200, a reporting device that reports a failure of the device that constitutes the water flow generator 100, Includes lighting equipment.

It is configured as follows. In addition, the water flow generation device 100 converts the flow velocity energy (water kinetic energy) of the water flow, which has been conventionally used only for the circulation of water such as a lake, into electrical energy and uses (regenerates) the lake, etc. Clean energy that is kind to the earth while performing environmental purification (environmental improvement), auxiliary power of the water flow generator 100 itself, power of peripheral equipment 52 (measuring equipment, reporting equipment, lighting equipment, etc.), disasters, etc. It can be used as power for the auxiliary power supply in the event of an abnormal emergency.

  In the first embodiment, the following effects can be obtained.

  In the first embodiment, as described above, the power generation unit 30 is configured to generate electric power when the power generation impeller 31 is swiveled by the water flow generated by the water flow impeller 21 of the water flow generation unit 20. To do. Accordingly, power generation can be performed if the casing 10 portion of the water flow generation device 100 is submerged without selecting a place where the water flow generation device 100 is to be arranged, so that the degree of freedom in installation conditions can be increased. it can. In addition, by integrally configuring in series so that the power generation unit 30 generates power by the swirling drive of the power generation impeller 31 by the water flow generated by the water flow impeller 21 of the water flow generation unit 20, Since the water flow generation unit 20 and the power generation unit 30 are both disposed in water very easily, unlike the conventional case where a windmill is provided on the surface of the water and the water flow generation unit 20 is driven, the apparatus is reduced in size and weight. (Space saving) can be achieved. As a result, a device excellent in portability can be temporarily installed without being fixedly installed (it can be moved and installed by human power without using heavy equipment).

  In the first embodiment, as described above, the power generation impeller 31 is configured to have a function of rectifying the water flow generated by the water flow generation unit 20. As a result, power generation can be performed using the impeller 31 that is used to rectify the water flow as an impeller 31 for generating power in a portion such as a rectifying plate or a guide vane that has a rectifying function. In addition, since there is no need to provide a separate rectifying component (such as a rectifying plate or guide vane), the size and weight can be reduced, and the flow velocity energy of the water flow can be effectively used as electrical energy while the water flow is efficiently ejected far away by the rectifying action. Can be reused.

  In the first embodiment, as described above, the power generation unit 30 is disposed on the side where the water flow generated by the water flow generation unit 20 is supplied so as to face the water flow generation unit 20. Thus, for example, in view of the strong air blowing on the front of the fan that everyone has experienced and recognized and the low suction air on the back of the fan, the water flow corresponding to the back side of the electric fan 30 Unlike the case where the generation unit 20 is arranged on the suction flow side where the water is absorbed weakly, the generation unit 20 is arranged on the side of the strong water supply flow generated by the water flow generation unit 20 corresponding to the front side of the fan. Thus, a water flow having a large flow velocity energy can be efficiently converted into electric energy.

  Moreover, in 1st Embodiment, the impeller 31 for electric power generation is equipped in the water inlet 11 side of the electric power generation part 30 as mentioned above. Accordingly, the water flow flowing into the power generation impeller 31 is suppressed from being obstructed by the main body portion 32 (a portion including a generator or the like) of the power generation unit 30, thereby corresponding to the front side of the electric fan. Since the water flow generated by the water flow generation unit 20 and having a large momentum of flow velocity energy flows smoothly and directly into the power generation impeller 31 without resistance, the flow velocity energy generated by the water flow generation unit 20 is further increased. Can be efficiently converted into electric energy without waste.

  In the first embodiment, as described above, the water flow impeller 21 of the water flow generation unit 20 is mounted on the water supply port 12 side of the water flow generation unit 20 so as to face the water flow impeller 21. In addition, the power generation unit 30 is equipped with a power generation impeller 31. As a result, a member that obstructs the water flow such as the main body portion 22 (portion including a motor) of the water flow generation unit 20 is not disposed between the water flow impeller 21 and the power generation impeller 31. From the above, by suppressing the loss of the water flow, the water supply flow having a strong momentum generated by the water flow generation unit 20 and having a large flow velocity energy as described above can be applied to the entire water absorption surface of the opposing power generation impeller 31 without resistance. Since the water flows smoothly and directly, the water flow having a larger flow velocity energy than the above effect is efficiently converted into electric energy without waste, and the water flow is sufficiently separated from the water inlet 11 at a position in the housing 10. Since the water flow impeller 21 is equipped, even in a low water level installation where a sufficient distance from the water surface cannot be obtained, the water flow impeller 21 can be normally operated while preventing air entrainment from the water surface. Since the water absorption from the back, while preventing accidents such as abnormal vibration or abnormal wear due to air inclusion at the time of water absorption, it is possible to perform a stable water supply.

  Further, in the first embodiment, as described above, the power storage unit 41 that stores the power generated by the power generation unit 30 is provided. As a result, the power generated by the power generation unit 30 can be used as an auxiliary power source in an emergency, for example, for driving the water flow generator 20 or for lighting, or for supplying power to the peripheral device 52 at normal times. Appropriate use can be made accordingly.

  Moreover, in 1st Embodiment, based on the operation command from the operation part 43 as mentioned above, control of the electric power feeding to the water flow generation part 20 from the electrical storage part 41 or the commercial power supply 51, and this electrical storage part 41 are mentioned. A control unit 42 is provided for performing control of power supply to the peripheral device 52. Thereby, by the operation of the operation unit 43 by the user (based on the user's judgment), the power supply from the power storage unit 41 or the commercial power source 51 to the water flow generation unit 20 and the power storage are appropriately performed according to the situation. Since the power supply from the unit 41 to the peripheral device 52 can be switched, as described above, for example, in the state where the auxiliary power supply is secured in an emergency or the power supply from the commercial power supply 51 is stopped, the power storage unit By continuing to supply water by supplying power from 41 to the water flow generating unit 20 via the control unit 42 for a predetermined time, power consumption of the commercial power supply 51 can be saved.

(Second Embodiment)
Next, a second embodiment of the present invention will be described with reference to FIG. In the second embodiment, the housing 10 is configured to be splittable.

  As shown in FIG. 4, the water flow generator 100 having a power generation function according to the second embodiment includes a housing 10. The housing 10 is configured to be divided into a first portion 111 in which the water flow generation unit 20 is mounted and a second portion 112 in which the power generation unit 30 is mounted. Specifically, the casing 10 is configured to be separable into the first portion 111 on the X1 direction side and the second portion 112 on the X2 direction side in the direction (X direction) in which the casing 10 extends.

Although provided, it may be a one-touch joint. In addition, the flange 117 is desirably provided on the water supply port 12 side (X2 direction side) of the second portion 112, but it may be a one-touch joint, and is desirably provided with a flange 118 also on the X1 direction side. However, it may be a one-touch joint. The first portion 111 and the second portion 112 are preferably configured to be joined by the flange 115 and the flange 118.

  Moreover, the 1st part 111 to which the water flow generation | occurrence | production part 20 is mounted | worn and the 2nd part 112 to which the electric power generation part 30 is mounted | worn are respectively comprised so that it can carry alone (in the state mutually isolate | separated).

To do. This makes it easy for the water flow generating device 100 having the power generation function with the optimum capacity according to the field conditions to the water flow generation section 20 with the optimal water flow generation capacity or the power generation section 30 with the desired power generation capacity according to the site. The power generation unit can be combined, and only the first part 111 provided with the water flow generation unit 20 is disposed in a lake or the like, and then (if necessary to generate power) as necessary. In addition to being able to generate power by connecting the second part 112 to which the 30 is mounted to the first part 111, even if the water flow generation unit 20 or the power generation unit 30 fails, the failed By exchanging only the first part 111 or the second part 112 to which the water flow generation unit 20 or the power generation unit 30 is attached, the operation of the water flow generation device 100 having a power generation function can be continued.
