Description

[Technical Field]

[0001] The present invention relates to a hydroelectric power generating device and a method of generating hydroelectric power using a water intake mechanism, a siphon mechanism and a power generating mechanism. [Background technology]

[0002] FIG. 1 of Patent Document 1 shows an example of the overall shape of a conventional reservoir-type dam hydroelectric power generating device. As shown in Figure 1, this hydroelectric power plant is designed so that the water used for generating electricity flows down a waterway from a reservoir, generates electricity at the power plant, and then passes through a discharge channel and is released into the river.The released water turns into steam, becomes rain, and returns to the reservoir, following the natural environmental circulation cycle of a conventional reservoir dam. Patent Document 2 describes a method for taking in water using a water intake device that utilizes centrifugal force. Although there are problems with the quality of water used for power generation during dry periods when there is no rain, we learned that the problem can be solved by installing a water intake device.

[0003] [Patent Document 1] Patent No. 6644344 [Patent Document 2] Special Publication No. 2009-522501 Summary of the Invention [Problem to be solved by the invention]

[0004] The hydroelectric power generation equipment that was originally conceived had the problem of having a small total generating capacity. [Means for solving the problem]

[0005] This hydroelectric power generation device utilizes the characteristics of siphon motion, which utilizes a mechanism in which a liquid ascends through a pipe with no gaps and is transported past a point higher than its original position.The device is characterized by having a siphon mechanism that has a water tank (1), a water pressure pressurizer (14), a rotating shell central axis (4), a rotating shell water wheel (11), a straightening plate (13) fixed to the water tank (1), a rotating shell (2), a spiral plate (3) installed inside the rotating shell (2), a vacuum water tank (7), an air valve (8), a water level sensor (19), a water conduit (9), and an on-off valve (16) and has the function of performing siphon motion; a water intake mechanism that has the function of sucking water for power generation from the water tank (1) inside the device to the vacuum water tank (7); and a power generation mechanism that has the function of generating electricity from the vacuum water tank (7) through the water conduit (9), a power generating water wheel (10), and a discharge pipe (12). [Effects of the Invention]

[Brief explanation of the drawings]

[0007] [Figure 1] 1 is a cross-sectional view of a hydroelectric power generation device showing an embodiment of the present invention, in which arrows indicate the flow paths of power-generating water. DETAILED DESCRIPTION OF THE INVENTION

[0008] (Embodiment 1) FIG. 1 is a cross-sectional view of a hydroelectric power generating device showing an embodiment of the present invention. As shown in Figure 1, the hydroelectric power generation device illustrating an embodiment of the present invention has a water intake mechanism that connects a water tank 1 and a vacuum water tank 7 arranged above the water tank 1, and includes a rotating cylinder central axis 4, a rotating cylinder water wheel 11, a straightening plate 13, a spiral plate 3 fixed to the rotating cylinder central axis, a rotating cylinder 2 fixed to the outer surface, an air valve 8, a water level sensor 19, and an on-off valve 16. The siphon mechanism has a mechanism for transporting liquid up a tight pipe and passing through a point higher than the original position, from the water tank 1 to the rotating cylinder 2, the vacuum water tank 7, the air valve 8, the water level sensor 19, the water pipe 9, and the on-off valve 16. The power generating mechanism has a power generating water turbine 10 capable of generating power using the power generating water flowing down from the vacuum water tank 7 to the water tank 1, and also has a water conveyance pipe 9 and a drainage pipe 12.

[0009] (Water intake mechanism) A water intake mechanism having a water tank 1, a hydraulic pressurizer 14, a rotating cylinder central shaft 4, a rotating cylinder water wheel 11, a straightening plate 13 fixed to the water tank 1, a rotating cylinder 2, a spiral plate 3 provided inside the rotating cylinder 2, a vacuum water tank 7, an air valve 8, and a water level sensor 19, and having the function of drawing up water for power generation from the water tank 1 to the vacuum water tank 7.

[0010] (Siphon principle) A system in which a liquid is transported up a tight tube, passing through a point higher than its original position.

[0011] (siphon mechanism) A siphon mechanism having a water tank (1), a hydraulic pressurizer (14), a central rotating shaft (4), a rotating barrel water wheel (11), a straightening plate (13) fixed to the water tank (1), a rotating barrel (2), a spiral plate (3) provided inside the rotating barrel (2), a vacuum water tank (7), an air valve (8), a water level sensor (19), a water pipe (9), and an on-off valve (16), and having the function of performing siphon movement.

[0012] (Power Generation Mechanism) A power generation mechanism having a vacuum water tank 7, a water pipe 9, an on-off valve 16, a power generating water turbine 10, and a drain pipe 12, and having the function of generating power.

[0013] The water tank 1 is a container for storing water for power generation. The shape of the water tank 1 is circular in plan view. The water tank 1 has a rotary barrel water wheel 11 attached therein. The water tank 1 is attached by preparing a recess at the location where the mounting portion 13a is to be installed.

[0014] The water pressurizer 14 includes a pressurized water distribution pump unit. The water pressure pressurizer 14 is operated to pressurize the water for power generation, and has the output to operate the rotational motion normally.

[0015] The central axis 4 of the rotating cylinder is a central axis that supports the spiral plate 3 and the rotating cylinder 2. The lower central shaft fixing portion 6 is attached to the lower center of the water tank 1. The upper central shaft fixing portion 5 is the upper center portion of the vacuum water tank 7 .

[0016] The shape of the water receiving plate of the rotating barrel water turbine 11 is a bowl-shaped shape that prevents the water for power generation from escaping, making full use of the water for power generation and allowing for good agitation inside the water tank 1.

[0017] The current plate 13 has a disk shape and a structure in which a honeycomb pattern is formed from the front surface to the back surface, and is a member that immediately changes the rotating flow into a vertical flow after it flows inside, and the thickness of the member that causes the change and the lean honeycomb structure provide strength. The mounting portion 13a is the outer peripheral portion of the current plate 13, and is attached in close contact with a recessed portion of the inner periphery of the water tank 1. The straightening plate 13 utilizes the vertical flow of the power-generating water to prevent adverse effects of inflow caused by the rotation of the spiral plate 3.

[0018] The rotating cylinder 2 has a truncated cone shape. This results in a structure in which the inner periphery and outer periphery of the spiral plate 3 are tightly connected to the inner periphery of the rotating barrel 2 and the outer periphery of the central shaft 4 of the rotating barrel. The diameter of the outlet at the upper end 2a of the rotating cylinder is small, which increases the pressure and flow rate of the water jetted out for power generation. The diameter of the inlet at the lower end 2b of the rotating cylinder is large, and the structure is such that a large amount of power-generating water can be taken in.

[0019] The spiral plate 3 has an angle and curvature that provides the best pushing-up and sliding effect. The spiral plate 3 is designed to have a structure that suppresses the surface movement of the power-generating water and the generation of bubbles while achieving the maximum effect of the pushing-up action with the optimum number of rotational movements.

[0020] The outer plate 15 of the rotating shell protects the rotating shell 2 from damage caused by external intrusions and wind and rain. In addition, damage to the surrounding area caused by the scattering of power generation water due to the rotation of the internal rotating cylinder 2 is eliminated. This protects the equipment from insufficient strength due to distortion and vibration caused by the rotation of the rotating shell 2.

[0021] The vacuum water tank 7 is a second container that stores water for power generation. The vacuum water tank 7 is disposed above the water tank 1 . When pressurized power-generating water flows into the vacuum water tank 7 from the upper end 2a of the rotating cylinder, the rotational movement of the spiral plate 3 carries air bubbles along with it, and in order to maintain a vacuum state, the air bubbles are removed by the air valve 8, and the vacuum state is confirmed and maintained by detection by the water level sensor 19. The vacuum water tank 7 is designed to have a shape and capacity that minimizes resistance to inflow, outflow, water pressure, and water flow. An air valve 8 is attached to the area where the air bubbles generated from the discharge port at the top of the rotating cylinder 2 are concentrated, and the air bubbles are removed. The vacuum water tank 7 has a structure that maintains a vacuum state without bubbles and does not lose siphon movement.

[0022] The air valve 8 has a structure for removing air such as bubbles that flow into the vacuum water tank 7.

[0023] The water level sensor has a structure that notifies the state of the amount of water for power generation inside the vacuum water tank 7 and detects whether a vacuum state has been reached.

[0024] The on-off valves 16a and 16b are used for repairs and inspections of the water conduit 9 and the power generating turbine 10, and for power generation and other operations by opening and closing when power generating water is flowing in and out. The on-off valve 16b closes before siphoning occurs to help store the power-generating water, and when the water pipe 9 is filled with water, it opens immediately to cause siphoning. The on-off valves 16 a and 16 b have an internal diameter that is the same as the internal diameter of the water conduit 9 .

[0025] The outlet diameter of the water conduit 9 is set to be the same as the inlet diameter of the power generating water turbine 10. The end connection portion of the water conduit 9 may have a flange structure and a special pipe structure. The length of the water conduit 9 is determined by calculating the dynamic and static water pressures of the inflowing water.

[0026] The power-generating water turbine 10 is equipped with a generator. Depending on the power generation capacity, a generator and a power-generating water turbine are selected, and the flow rate and diameter of the power-generating water for the power-generating water turbine are determined.

[0027] As shown in FIG. 1, the water tank 1 is provided with a generating water inlet 17, an on-off valve 17a, a generating water outlet 18, and an on-off valve 18a. [Industrial Applicability]

[0028] This invention is a hydroelectric power generation method born from the reverse idea of ​​raising water for power generation from the bottom up. This method utilizes the siphoning motion of the water used for power generation to reduce the burden of the movement required to suck it up to the upper reservoir, thereby reducing the power burden during power generation and increasing power generation efficiency. Unlike previous hydroelectric power generation systems, the water used for generating electricity is circulated within the device. This invention can easily be used as a power source for key industries in each city. Contributing to reducing CO2 emissions, which is what society as a whole is seeking A method of generating electricity using siphon motion can contribute to solving familiar social problems. This will result in significant changes in the cost recovery rates of electricity supply companies, allowing them to supply electricity to consumers at significantly lower costs.
