Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power generator.

[0002]

2. Description of the Related Art Conventionally, in various buildings such as apartment houses, condominiums, office buildings, store buildings, etc.
Water is supplied to various places by the water tank system. In this case, the tap water supplied through the water pipe is temporarily stored in the receiving tank, and the tap water in the receiving tank is stored in the tank provided on the roof of the building by the pump. Then, the clean water in the tank is dropped through a clean water pipe provided in the building to be pressure-fed to various places in the building. As a result, it is possible to stably supply the clean tap water to various places in the building.

However, when the building is a tall building such as a high-rise building or a super high-rise building, since there is a large drop from the roof to the lower floors, the water in the tank is dropped to supply water to the lower floors. Then, the water pressure becomes too high, which makes it difficult to adjust the flow rate. So in tall buildings,
A pressure reducing valve is provided in a water supply pipe provided in the building in accordance with a drop from the roof to reduce the water pressure. As a result, the pressure of clean water is relieved even on the lower floors of tall buildings, and the flow rate can be adjusted easily.

Further, sewage such as rainwater and domestic wastewater in a building is temporarily stored in a sewage receiving tank installed above ground or underground, and then drained to a public sewer pipeline. . Also in this case, in a high building, since the difference from the roof or high floor to the water receiving tank is large, if rainwater that fell on the roof or sewage such as domestic wastewater from the high floor directly flows into the water receiving tank, The sewage pipe and the water receiving tank arranged in the building will be damaged. Therefore, in a tall building, a preliminary water tank is installed for each predetermined floor,
The sewage drained from the higher floors is made to sequentially flow into the water receiving tanks arranged for each predetermined floor, and is dropped in a cascade form. As a result, the pressure of sewage from the higher floors of a tall building is relieved, and the sewage pipe and the water receiving tank are not damaged.

[0005]

However, in the facility for supplying the clean water in the building, the potential energy of the water stored in the tank arranged on the rooftop is wasted. In particular, in the case of a tall building, the water stored in the tank disposed on the rooftop has a large potential energy, but the potential energy is not utilized at all, and rather the pressure reducing valve causes It wastes potential energy. On the other hand, since the position of the tank arranged on the roof is high, the work of the pump for supplying clean water to the tank becomes extremely large and the pump consumes a large amount of electric power.

[0006] Similarly, with respect to equipment for draining sewage such as rainwater and domestic wastewater in the building, the potential energy of water is wasted as well. Especially for tall buildings,
Sewage such as rainwater that fell on the rooftop and domestic wastewater from the upper floors,
Despite having a large potential energy, the potential energy is not utilized at all, but rather the water tank wastes the potential energy. Moreover, since the water receiving tank is arranged for each predetermined floor, the cost becomes high.

The present invention solves the above conventional problems,
By arranging a generator in an inflow conduit through which water flows into a storage tank that temporarily or long-term stores tap water or sewage or an outflow conduit through which water flows from the storage tank, the inflow conduit or outflow An object of the present invention is to provide a power generation device that can efficiently recover the energy of water flowing through a pipeline and generate power.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a view showing the arrangement of a hydroelectric generator of a power generator according to the first embodiment of the present invention, and FIG. 2 is a configuration of a control device of the power generator according to the first embodiment of the present invention. It is a conceptual diagram which shows.

In FIG. 1, 11 is a building such as an apartment, a condominium, a housing complex, an office building, a store building, etc., but it may be a building used for any purpose. Here, the case where the building 11 is, for example, a 50-story high-rise building will be described.
The number of floors of 1 may be any number, and the building 11 may be a low-rise building. In the building 11, tap water such as drinking water is supplied to various places by a so-called water receiving tank method.

In this case, the clean water supplied from the water pipe 12 installed underground such as clean water for supplying clean water such as drinking water is temporarily stored in the clean water receiving tank 13. The clean water receiving tank 13 may be installed underground or above ground. A pumping pump 14 is disposed near the clean water receiving tank 13, and the clean water receiving tank 1 is provided.
The clean water stored in 3 is pumped by the pumping pump 14 to a water supply tank 16 as a water storage tank arranged on the roof of the building 11. Thereby, the clean water receiving tank 13
The clean water stored therein flows through the water supply tank water supply pipe 15 serving as an inflow pipe of the water supply tank 16 and flows into the water supply tank 16 to be stored. Since the water supply tank 16 is arranged at a high place apart from the ground, it is desirable that the pumping pump 14 is a pump having a large head such as a multistage pumping pump.

The clean water stored in the water supply tank 16 is supplied to various places in the building 11 through an internal water supply main pipe 17 as an outflow pipe line of the water supply tank 16. Here, as shown in FIG. 1, the internal water supply main pipe 17 extends from the bottom of the water supply tank 16 to the building 1
1 extends almost vertically and linearly to the bottom layer. In addition, the internal water supply main 17 has the building 11
A plurality of branch pipes 17a stretched around each floor are connected. As a result, the clean water stored in the water supply tank 16 falls from the water supply tank 16, passes through the internal water supply main pipe 17 and the branch pipe 17a, and is washed in various places in the building 11 in the kitchen and kitchen. , Even to the faucet installed in the toilet etc. In this case, the tap water stored in the water supply tank 16 disposed on the roof of the building 11 is utilized to supply the tap water to the faucet.

Here, the internal water supply main pipe 17 is provided with a hydraulic power generator 21 for each predetermined head. It should be noted that although the head can be set as appropriate, in the present embodiment, as shown in FIG. 1, a total of five hydroelectric generators 21 are provided for every tenth floor. That is, the 10th floor,
The hydroelectric generators 21 are arranged on the 20th floor, the 30th floor, the 40th floor, and the 50th floor, which is directly below the bottom of the water supply tank 16, respectively.

In this case, the clean water falling from the water supply tank 16 and flowing through the internal water supply main pipe 17 is the hydroelectric generator 21.
The turbine is rotated, and a direct current is generated by the generator attached to the rotating shaft of the turbine. Then, the direct current is supplied from the hydroelectric generator 21 to the battery 22 and the inverter 23, as shown in FIG. A fuse 25 and an ammeter 26 are preferably arranged on the power supply line 24. Thereby, the direct current is
Output line 2 after being converted into alternating current by inverter 23
It is output from 4a. The surplus DC current is stored in the battery 22 and is supplied to the inverter 23 as needed. The generator may be an alternating current generator that generates alternating current.

Further, pressure detectors are arranged at various places in the internal water supply main pipe 17, and a bypass pipe with a control valve for bypassing the water turbine of the hydraulic power generator 21 is provided in the internal water supply main pipe 17. It is desirable to be connected. In this case, the opening of the control valve can be adjusted to control the amount of tap water that rotates the water turbine so that the water pressure at each location of the internal water main pipe 17 becomes a predetermined value. For example,
When the consumption of clean water in each part of the building 11 is increased, the water pressure at the end portion of the branch pipe 17a may be too low. In such a case, by reducing the amount of clean water that rotates the turbine, it is possible to reduce the amount of clean water pressure drop by the turbine and prevent the decrease of water pressure at the end portion of the branch pipe 17a. . Further, the control of the amount of clean water that rotates the water turbine can be performed for each hydraulic power generator 21.

As described above, in the present embodiment, the hydraulic power generator 21 is arranged in the internal water supply main pipe 17, and the building 1
The electric power is generated by utilizing the potential energy of the clean water stored in the water supply tank 16 arranged on the rooftop. Therefore, it is possible to effectively recover the potential energy of the clean water, which has not been used conventionally, and use it as electric energy. For example, lighting the building 11 with the electric energy,
It can be used to drive a device such as an air conditioner of the building 11, or can be sold to a power company. Therefore, the maintenance cost of the building 11 can be reduced.

When the building 11 is a tall building such as a high-rise building, the water tank of the hydroelectric generator 21 is rotated, although the head from the water tank 16 to the lower floor is large. The water pressure of the clean water falling from the water drops. For this reason, the water pressure of the clean water falling from the water supply tank 16 is relieved, the pressure of the clean water flowing in the internal water supply main pipe 17 and the branch pipe 17a can be made appropriate, and the flow rate can be easily adjusted. In this case, it is not necessary to provide a device for relieving the water pressure of the tap water, such as the pressure reducing valve described in "Prior Art", and thus the cost of the water supply system for the building 11 can be reduced.

Further, in case of an emergency such as a disaster, by supplying the clean water stored in the water supply tank 16 through the internal water supply main pipe 17 and discharging the water, emergency power can be secured.

Next, a second embodiment of the present invention will be described. Note that description of the same configuration and operation as those of the first embodiment will be omitted.

To the internal drainage main pipe 31 to which the branch pipe 31a is connected. Then, since the internal drainage main pipe 31 is connected as an inflow conduit to a sewage water receiving tank 32 as a storage tank disposed underground or the like, sewage is temporarily stored in the sewage receiving water tank 32. The sewage once stored in the sewage receiving tank 32 is a sewer pipe 3 such as a public sewer.
It is discharged to 3 and sent to the treatment plant.

Here, the internal drainage main pipe 31 extends substantially vertically and linearly from the uppermost layer of the building 11 to the sewage receiving tank 32, as shown in FIG.
As a result, the sewage that has flowed into the plurality of branch pipes 31a stretched around each floor of the building 11 drops from the connection portion of the branch pipes 31a and passes through the internal drainage main pipe 31 serving as an inflow pipe line. , Flows into the sewage receiving tank 32. In this case, a plurality of branch pipes 31a stretched around each floor of the building 11
The sewage is made to flow into the sewage receiving tank 32 by utilizing the potential energy of the sewage flowing inside.

Here, the internal drainage main pipe 31 is provided with a hydraulic power generator 21 for each predetermined head. It should be noted that the head can be set as appropriate, but in the present embodiment, as shown in FIG. 3, a total of five hydroelectric generators 21 are provided for every tenth floor. That is, 40
The hydroelectric generators 21 are respectively arranged on the floors, the 30th floor, the 20th floor, the 10th floor, and the ground floor just above the sewage receiving tank 32. Then, the sewage that falls from the connecting portion of the branch pipe 31a and flows through the internal drainage main pipe 31 is the hydroelectric generator 2 described above.
The first turbine is rotated, and a direct current is generated by a generator attached to the rotating shaft of the turbine.

As described above, in this embodiment, the hydroelectric generator 21 is arranged in the internal drainage main pipe 31, and the building 1
The electric power is generated by utilizing the potential energy of the sewage flowing into the internal drainage main pipe 31 from a plurality of branch pipes 31a stretched around each floor. Therefore, it is possible to effectively recover the potential energy of sewage, which has not been used conventionally, and use it as electric energy. Therefore, the maintenance cost of the building 11 can be reduced.

When the building 11 is a high building such as a high-rise building or a super high-rise building, the water drop of the hydroelectric generator 21 is rotated although the head from the high floor to the sewage receiving tank 32 is large. , The water pressure of the sewage falling from the upper floors decreases. Therefore, the water pressure of the sewage falling from the upper floors is relieved, and the sewage receiving tank 32 flows through the internal drainage main pipe 31.
The pressure of the sewage flowing into the can be adjusted to an appropriate level, and the internal drainage main pipe 31 and the sewage receiving tank 32 will not be damaged. In this case, it is not necessary to dispose a device for relieving the water pressure of the sewage, such as the preliminary water tank described in "Prior Art", on each floor, so that the cost of the drainage system of the building 11 is reduced. be able to.

Next, a third embodiment of the present invention will be described. Note that description of the same configurations and operations as those of the first and second embodiments will be omitted.

FIG. 4 is a view showing the arrangement of the hydroelectric generator of the power generator according to the third embodiment of the present invention.

In this embodiment, a case will be described in which clean water is stored in a temporary storage tank 35, which is a storage tank temporarily arranged on each floor of the building 11. Here, the temporary storage tank 35 is arranged for permanent use like the clean water receiving tank 13, the water supply tank 16, the sewage receiving tank 32, etc. in the first and second embodiments. It is not a thing, but it is arranged for short-term use and can be removed immediately when it is no longer needed. The temporary storage tank 35 is arranged in an unused space such as a vacant room in the building 11 to store clean water. In addition, in the building 11 shown in FIG. 4, the temporary storage tank 35 is arranged on each floor, but it is not necessarily arranged on each floor, and is arranged only on a floor having an extra space such as a vacant room. Just set it up.

Here, the temporary storage tank 35 is provided for short-term use, and is to be immediately removed when it is no longer needed. Therefore, it is portable and portable, can be easily assembled and disassembled, can be folded when it is no longer needed, and can be folded into vinyl or rubber, such as a household pool for infants. Inflate air into a resin bag such as a balloon to make up the bottom and walls to inflate it, or put water in a resin bag such as vinyl or rubber like a water bed or water pillow to store it. It is preferably a water pillow type. The temporary storage tank 35 may be configured by connecting a plurality of small ones. For example, a temporary storage tank 35 may be formed by connecting a plurality of plastic tanks, drums and the like. In this case, the temporary storage tank 3 having a desired volume is irrespective of the size of the extra space such as the empty chamber.
5 can be arranged in the entire excess space.

A water supply pipe 37 as an inflow conduit of the temporary storage tank 35 is connected to a water supply main pipe 36 which is connected to a water supply for supplying drinking water or the like, and which is provided underground. The clean water flowing through the main water supply pipe 36 flows into the temporary storage tank 35. A return pipe 38 as an outflow pipe line is connected near the bottom of the temporary storage tank 35.
Here, the return pipe 38 is connected to the water supply main pipe 36. Therefore, the clean water stored in the temporary storage tank 35 can be returned to the water supply main 36 as needed.

Here, the return pipe 38 is provided with a hydraulic power generator 21 for each predetermined head. It should be noted that the head can be set as appropriate, but in the present embodiment, as shown in FIG. 4, a total of four hydroelectric generators 21 are provided for each floor. Then, the clean water flowing out of the temporary storage tank 35 arranged on each floor and dropped, and flowing through the return pipe 38 rotates the water turbine of the hydraulic power generator 21 and is attached to the rotating shaft of the water turbine. It is generated by a generator.

As described above, in the present embodiment, the hydroelectric generator 21 is arranged in the return pipe 38, and the clean water stored in the temporary storage tank 35 arranged in the vacant room of the building 11 or the like. It uses the potential energy that it has to generate electricity. Therefore, the potential energy of the clean water stored in the temporary storage tank 35, which has not been used conventionally, can be effectively recovered and used as electric energy.

The temporary storage tank 35 is arranged for short-term use, and can be immediately removed when it is no longer needed, and is used in a vacant room or the like in the building 11. It is arranged in an extra space that is not stored and stores clean water. Therefore, building 11

The water supply pipe 42 is connected to a water pipe (not shown) so that tap water as clean water can flow.
Therefore, the tap water flowing through the water supply pipe 42 rotates the hydraulic turbine of the hydraulic power generator 21, and the generator attached to the rotating shaft of the hydraulic turbine generates electric power. In this case, the pressure energy of tap water is used to generate electricity. Therefore, the water pressure of the tap water flowing through the water supply pipe 42 is relieved and flows into the washing machine 41 at an appropriate pressure. Therefore, it is not necessary to dispose a pressure reducing valve on the water supply pipe 42.

Further, drainage as sewage flowing out from the plurality of washing machines 41 passes through the collective drainage pipe 43 and flows into the drainage tank 44 for storage. Then, the drainage stored in the drainage tank 44 flows out from a drainage pipe 45 as an outflow conduit of the drainage tank 44 and flows into a public sewer or the like (not shown). Here, the drainage pipe 45 is connected to the hydroelectric generator 2
1, the wastewater flowing through the drainage pipe 45 rotates the water turbine of the hydroelectric generator 21, and the generator attached to the rotating shaft of the water turbine generates electric power. In this case, the potential energy possessed by the drainage flowing out of the drainage tank 44 can be effectively recovered and used as electric energy.

The current generated by the hydroelectric generator 21 is sent to the controller 46 provided in the coin laundry. Here, the controller 46 controls the current from the power source 48,
And controlling the current generated by the hydropower generator 21,
It is designed to be sent to the washing machine 41 and the illumination 47 of the coin laundry. That is, the current supplied from the power source 48 is reduced corresponding to the current generated by the hydraulic power generator 21. Therefore, the washing machine 41 and the lighting 4 of the coin laundry are constantly supplied with a necessary current.

As described above, in the present embodiment, in the coin laundry, the pressure energy of tap water is used to generate electric power, and the potential energy of the waste water discharged from the drain tank 44 is used. Since electricity is generated by using the electricity, it is possible to effectively recover the energy of tap water and waste water and use it as electric energy. Moreover, since the electric energy is used by the washing machine 41 and the lighting 47 in the coin laundry,
It is possible to reduce electricity charges for coin laundry.

Next explained is the fifth embodiment of the invention. Note that description of the same configurations and operations as those of the first to fourth embodiments will be omitted.

Further, drainage as sewage flowing out of the bath 61 flows through a drain pipe 65 into a public sewer or the like (not shown). Here, the hydroelectric generator 21 is disposed in the drain pipe 65, and the drain pipe 65
The wastewater flowing through the water turbine rotates the water turbine of the hydraulic power generator 21, and power is generated by the power generator attached to the rotating shaft of the water turbine. In this case, the potential energy of the waste water flowing out from the bath 61 can be effectively recovered and used as electric energy.

The current generated by the hydroelectric generator 21 is sent to the controller 46. Here, the controller 46
Controls the current from the power source 48 and the current generated by the hydraulic power generator 21, and sends the current to the operation panel 63 and the water purification module 50. That is, the power source 48 corresponds to the current generated by the hydraulic power generator 21.
It is designed to reduce the current supplied from the.

Here, the operation panel 63 is provided with buttons, switches and the like operated by the bather 62 to adjust the temperature and amount of the hot water stored in the bath 61. The operation of the water heater (not shown) and the opening / closing valve 64a is controlled according to the operation of the bather 62.

Further, a water purification module 50 is arranged in the circulation pipe line 51 for circulating the hot water stored in the bath 61, and the hot water flowing through the circulation pipe line 51 is purified by filtering. There is. In this case, the water purification module 50 includes a water purifier 52 arranged in the circulation pipeline 51,
The impurities in the hot water are removed by circulating the hot water inside the filter medium 52a arranged in the water purifier 52. The filter medium 52a is divided into a plurality of compartments, for example, three compartments, and while the hot water flows through one compartment, the other compartments are heated by the heater 54 so that the filtration function is restored. There is. Then, after a lapse of a predetermined time, the filter medium 52a is rotated by the motor 56, the hot water flows through the restored section, and the section through which the hot water has been flowing is heated by the heater 54. In this case, the operation of the motor 56 is controlled by the motor drive circuit 57, and the operation of the heater 54 is controlled by the heater drive circuit 55.

Next, the structure of the water purifier 52 will be described.

It is set up. The filter medium 52a is connected to the rotary shaft 56a of the motor 56 and is rotated by the motor 56. In addition, the filter medium 52
A partition plate 52c is attached between each section of a. Here, the partition plate 52c from the center of the filter medium 52a
To the outer end of the casing 52b is substantially equal to the radius of the casing 52b, and the outer end of the partition plate 52c moves while contacting the inner peripheral surface of the casing 52b.

A heat transfer plate 54a is attached to the inner peripheral surface of the casing 52b to transfer the heat of the heater 54. As a result, the section of the filter medium 52a in which hot water does not flow is efficiently heated and the filtering function is restored.

On the other hand, in the water purifier 52 shown in FIG. 8, instead of the motor 56, a vibration motor 66 for generating vibrations.
Is used. Therefore, the vibration generated by the vibration motor 66 is transmitted to the filter medium 52a via the rotary shaft 66a, and the filter medium 52a vibrates as indicated by an arrow A. As a result, the impurities adhering to the filter medium 52a fall, and when the on-off valve 58 is opened, the impurities flow out from the impurity discharge pipe 58a together with the hot water flowing through the filter medium 52a. As a result, the filtering function of the filter medium 52a is restored. The vibration motor 66 can also be applied to a motor that restores the filtering function of the filter medium 52a by heating, as shown in FIG.

As described above, in the present embodiment, the power is generated by using the pressure energy of the tap water and the potential energy of the waste water flowing out from the bath 61. Therefore, the energy possessed by tap water and waste water can be effectively recovered and used as electric energy. Then, the filtering material 52 of the water purifier 52 arranged in the circulation path 51 for supplying the electric energy.
Since it is used to restore the filtration function of a, the bathtub 6
The hot water in 1 can be efficiently purified at low cost. Further, since it is not necessary to replace the filter medium 52a, the maintenance cost of the water purifier 52 can be reduced.
