Patent Application
20170298895
The present invention is generally related to green power, and more particular to a system and a related method of integrally harnessing wind power, solar power, and hydraulic power.
Green power generation is the trend for the future. Among the various green power sources, wind power is often not persistent, and requires a certain degree of wind strength. Wind power generation therefore cannot sustain for a long period of time. Hydraulic power requires abundant water resource but water cannot be recycled. On the other hand, solar power is limited by climate condition and sunbeam direction.
Whether it is wind, solar, or hydraulic power that is harnessed, the generation device is usually designed for a single source. These green power sources are often not integrated and harnessed together.
A major objective of the present application is to integrate wind power, solar power and hydraulic power to recycle water resources and to produce electricity continuously with a limited amount of water.
The present disclosure teaches a green power generation system contains a pumping device, a wind-powered pumping device, a solar-powered pumping device, a water storage device, a first hydraulic generation device, a second hydraulic generation device, and a lighting device. The water storage device contains a container, an inlet pipe, and an outlet pipe. The system first uses the pumping device to retrieve water using an internal power source from a water source. Then, in accordance with a wind parameter and a solar parameter, the wind-powered and solar-powered pumping devices are selectively engaged to replace the pumping device. The water is stored in the water storage device in a higher place. As the water runs through the inlet pipe, it is pressurized to drive the first hydraulic generation device. Then the water's potential energy is used to drive the second hydraulic generation device as the water is recycled to the water source. The produced electricity is delivered to the pumping device and, if any remaining, then to the light device for illumination.
The foregoing objectives and summary provide only a brief introduction to the present invention. To fully appreciate these and other objects of the present invention as well as the invention itself, all of which will become apparent to those skilled in the art, the following detailed description of the invention and the claims should be read in conjunction with the accompanying drawings. Throughout the specification and drawings identical reference numerals refer to identical or similar parts.
Many other advantages and features of the present invention will become manifest to those versed in the art upon making reference to the detailed description and the accompanying sheets of drawings in which a preferred structural embodiment incorporating the principles of the present invention is shown by way of illustrative example.
The following descriptions are exemplary embodiments only, and are not intended to limit the scope, applicability or configuration of the invention in any way. Rather, the following description provides a convenient illustration for implementing exemplary embodiments of the invention. Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims.
As shown in
A pumping device 1 is provided for retrieving water.
A wind-powered pumping device 2 is electrically connected to the pumping device 1, which is actuated when a wind parameter reaches a threshold and replaces the operation of the pumping device 1.
A solar-powered pumping device 3 is electrically connected to the pumping device 1, which is actuated when a solar parameter reaches a threshold and replaces the operation of the pumping device 1. The solar-powered pumping device 3 contains a pump unit 21. The solar-powered pumping device 3 may operate independently to retrieve water, or simply provide electricity to the pumping device 1.
An actuation module 9 is electrically connected to the pumping device 1, the wind-powered pumping device 2, and the solar-powered pumping device 3, which is for setting up the wind and solar parameters and a time interval, and is for switching the pumping devices.
A water storage device 4 is disposed above the pumping device 1 and is connected to the pumping device 1, the wind-powered pumping device 2, and the solar-powered pumping device 3. The water storage device 4 contains a container 41, an inlet pipe 42 whose two ends connect the pumping device 1 and the container 41, respectively, an outlet pipe 43 whose two ends connect the container 41 and a water source, respectively, a purification unit 44 on the inlet pipe 42, and a pressurization unit 421 on the inlet pipe 42 for driving water to engage a first hydraulic generation device 5.
The first hydraulic generation device 5 is configured above the container 41 and is engaged by the water delivered by the inlet pipe 42. A second hydraulic generation device 6 is configured along the outlet pipe 43 which is driven by the water in the container 41's potential energy.
A lighting device 7 is electrically connected to the wind-powered pumping device 2, the solar-powered pumping device 3, the first hydraulic generation device 5, and the second hydraulic generation device 6. The light device 7 contains an AC-DC rectifier unit 71, a regulator unit 72, and a timing unit 73. The rectifier unit 71 and the regulator unit 72 are for charging the lighting device 7, and the timing unit 73 is for turning on the lighting device 7 and for charging the lighting device 7 at specific times.
An electricity storage device 8 is electrically connected to the wind-powered pumping device 2, the solar-powered pumping device 3, the first hydraulic generation device 5, and the second hydraulic generation device 6.
A green power generation method according to an embodiment of the present invention contains the following steps:
As shown in
The wind-powered and solar-powered pumping devices 2 and 3 operate using the siphon principle. The water is retrieved to the water storage device 4 at a higher place and, before the water enters the container 41, the water is pressurized using the pressurization unit 421 on the inlet pipe 42 so as to drive the first hydraulic generation device 5 in a second mode of electricity generation. The water in the container 41 is then directed to the water source through the outlet pipe 43 by gravity and, along the process, the water drives the second hydraulic generation device 6 so as the convert the water's potential energy into electrical energy in a third mode of electricity generation. After driving the second hydraulic generation device 6, the water continues to flow back to the water source.
The present invention therefore provides long-term electricity generation utilizing only a limited amount of water. The produced electricity is further stored in the electricity storage device 8 for the pumping device 1 in case there is no wind or sunlight. The produced electricity can also be directed to the light device 7. With the control of the timing unit 73, the electricity can be used to charge or discharge. For example, from 0800 to 1600, the produced electricity is converted into low-level stable DC by the rectifier unit 71 and the regulator unit 72 for charging. Then, from 18:00 to 0600, the produced electricity is directly supplied to the lighting device 7 for illumination. The present embodiment also utilizes a purification unit 44 so that the water not only can be used for electricity generation but also can be used for household consumption.
While certain novel features of this invention have been shown and described and are pointed out in the annexed claim, it is not intended to be limited to the details above, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing in any way from the claims of the present invention.
