Circulatory operation of hydroelectric power generating water

Abstract

To provide a hydroelectric power generating apparatus that eliminates waste of hydroelectric power generating water.SOLUTION: In a circulation operation method, with no water discharged to or stored in a river, a pond or the like, operation of pumping water placed in a lower water storage tank 1 to an upper storage tank 6 is carried out in the following manner: hydroelectric power generating water entered into a water storage suction pump with a structure composed of spiral plates (vanes) 3 installed inside is elevated using rotational motion and centrifugal force generated by rotation of a water flow cylinder 2. The hydroelectric power generating water that reaches the upper water storage tank 6 flows into a conduit pipe 8, descends while undergoing reverse siphoning, rotates a power generating water wheel (turbine) 9, and terminates the reverse siphoning at an inlet of a water flow cylinder rotating water wheel 10. The water flow cylinder rotating water wheel 10 is driven by natural downward flow of the hydroelectric power generating water to rotate. The hydroelectric power generating water flows down through a drainage pipe 11 and enters into the lower water storage tank 1, thereby allowing the water to flow between the lower water storage tank 1 and the drainage pipe 11.SELECTED DRAWING: Figure 1

Description

[Technical Field]

[0001] This invention is a circulation activity in which a fixed amount of water is used for hydroelectric power generation. [Background technology]

[0002] The flow of water used for hydroelectric power generation in current hydroelectric power plants is a single activity of hydroelectric power generation, where water stored in dams or ponds flows through water pipes to turn the turbines of generators, and then is released into rivers or ponds to complete the power generation. Summary of the Invention [Problem to be solved by the invention]

[0003] A water recycling activity for power generation that eliminates the discharge of water for hydroelectric power generation into rivers and ponds and converts the discharge activity into a water recycling activity for hydroelectric power generation, eliminating the waste of water discharge for hydroelectric power generation.

[0004] The water for hydroelectric power generation is guided by the rotation of the water storage suction pump, which is composed of a water flow tube 2 and a spiral plate (blade) 3, from the lower water tank 1 to the upper water tank 6, where it flows into a water conveyance pipe 8, then flows down to a generator water wheel (turbine) 9, turns the generator water wheel (turbine) 9, and then flows into a pipe connected to the water flow tube rotating water wheel 10, where it completes the reverse siphon movement just before the water flow tube rotating water wheel 10, becomes a natural discharge, turns the water flow tube rotating water wheel 10, flows down to a drainage pipe 11, and returns to the lower water tank 1, this is the circulation activity of the water for hydroelectric power generation. [Means for solving the problem]

[0005] The principle of the siphon is the principle of natural flow, where a liquid is filled into a hose from a certain point and moves to a lower point, passing through a higher point. However, the water for hydroelectric power generation is pumped up and pressurized by a water suction pump to a higher point (upper water tank 6), where the pressurized water flows into the water conduit 8 and the reverse siphoning motion ends at the inlets of the power generating water turbine 9 and the water flow barrel rotating water turbine 10 (the section from the water conduit 8 to the inlet of the water flow barrel rotating water turbine 10 is the reverse siphon; a reverse siphon is the act of moving from a higher point to a lower point).

[0006] Calculations related to water for power generation are carried out using hydraulic calculations. There are some areas where calculations for water pressure, water volume, water flow, flow velocity, etc. are required, including static and dynamic water pressure. The length of the water conduit 8 is the longest among the circulating water for hydroelectric power generation, and careful design calculations are carried out for the water conduit 8 using calculations such as the pressure coefficient to ensure there is no risk of cracking or damage, and it is manufactured according to the processing drawings.

[0007] The first step is to determine the required generating capacity of the hydroelectric power generation equipment, and once the generating capacity is known, the generating capacity and quantity of generators can be determined. Accordingly, the inlet diameter, surface area, water pressure, flow rate, water current and flow velocity of the generating water turbine 9 can be determined. The outlet for generating water from the upper water tank 6 can be made radial, and the diameter of the water conveyance pipe 8 and the water pressure, water volume, water current and flow velocity of the water discharged into the generating water turbine 9 can be determined. The number of impellers for the water flow cylinder rotating water turbine 10 can also be determined. The installation angle of the point where the drain pipe 11 piping connects to the lower water tank 1 can also be determined, and the structure and production drawings of each part can be created.

[0008] The capacity of the water for hydroelectric power generation in the lower water tank 1 is calculated by subtracting the inner diameter of the water flow barrel 2 and the area of ​​the spiral plate 3 from the water storage suction pump, the internal capacity of the upper water tank 6, the number of radially installed water conveyance pipes 8 (calculation of the dynamic water pressure required for the power generating water wheel (turbine) 9 to turn the water wheel), the total power generating water capacity up to the end of the same number of drainage pipes 11 as the number of connection points of the power generating water wheel (turbine) 9, and the capacity of the lower water tank 1 that is large enough to prevent water for hydroelectric power generation from splashing out of the lower water tank 1 when the make-up water tank 13, excess water tank 15, and water flow barrel 2 are in operation, and then calculating the capacity.

[0009] The lower water tank 1 vortex water flow prevention plate 18 is installed in the lower water tank 1 as shown in [Figure 1-1] so that the rotation of the water flow cylinder 2 in the lower water tank 1 does not cause a vortex motion of the hydroelectric power generation water inside the lower water tank 1, and strives to prevent vortex motion, creating an environment for hydroelectric power generation water in which the hydroelectric power generation water in the water flow cylinder 2 can be easily pushed up by the spiral plate 3 when it is sucked up (the upper part of the lower water tank 1 vortex water flow prevention plate 18 extends to the space above the hydroelectric power generation water volume, and the lower part is installed in a part lower than the water flow cylinder 2 so as not to interfere with the discharge activity of the inlet / outlet dual-use pipe 12 when it is discharged).

[0010] The water storage suction pump has a spiral plate 3 tightly fitted inside the water flow cylinder 2 and connected to the central axis 4 of the water flow cylinder, and the water wheel 10 for rotating the water flow cylinder is fixedly connected to the outer periphery of the water flow cylinder 2 and rotates around the fixed axis of the fixed part 5 of the water flow cylinder to suck up water for hydroelectric power generation.

[0011] The diameter of the outlet of the water flow tube 2 is the diameter of the outlet where the water pressure, water volume, water flow and flow velocity are increased based on the diameter and area of ​​the inlet of the power-generating water wheel (turbine) 9 and the total area of ​​the total number of power-generating water wheel (turbine) 9, and the diameter of the inlet of the water flow tube 2 is the diameter calculated from the maximum diameter area that can obtain the volume and capacity to easily push up the water pressure, water volume, water flow and flow velocity of the outlet of the water flow tube 2 (the rotational movement of the water flow tube 2 creates centrifugal force, which has the effect of pushing up the water for hydroelectric power generation, increasing the water pressure, water volume, water flow and flow velocity).

[0012] The angle of the spiral plate (vane) 3 and the curvature of the spiral plate (vane) 3, which can ensure sufficient water pressure and water volume, as well as the inner diameter dimensions that are in close contact with the central axis 4 of the rotating cylinder 2 and the water flow cylinder, are calculated, and the number of spiral plates (vanes) 3 that can generate the maximum effect of centrifugal force and rotation speed in the upward pushing action of the water for hydroelectric power generation is calculated.

[0013] The upper water tank 6 has a shape and capacity that minimizes resistance to water pressure and water flow during inflow and outflow, and the bubbles generated from the water flow tube 2 are calculated, and an air valve 7 is attached to the part where the bubbles concentrate, and the overall shape and internal area of ​​the upper water tank 6 that eliminates the bubbles is calculated, and the upper water tank 6 maintains a vacuum state free of air bubbles and does not lose its reverse siphoning motion, and the overall shape and structure of the upper water tank 6 and maintenance of the air valve 7 are taken into consideration, and the connecting part of the radially installed discharge port has a flange structure that makes work and maintenance easy.

[0014] The inlet and outlet of the water conduit 8 have a flange structure, and the outlet of the water conduit 8 is an irregular pipe with a narrow diameter to amplify the water pressure, water volume, water flow, and flow velocity of the power generating water turbine; the outlet of the upper water tank 6 has a wide diameter structure and the outlet of the water conduit 8 is narrowed to amplify the water pressure, water volume, water flow, and flow velocity; several types of water conduit 8 structures (the water conduit 8 has a shape in which a straight pipe and an irregular pipe are connected, or the shape of the diameter of the start and end points of the water conduit 8 is changed, and the connection points for connecting extension pipes have a flange structure; the water conduit 8 is designed and manufactured with its length determined by calculating the dynamic water pressure and static water pressure required to turn the hydroelectric power generating water turbine 9).

[0015] The selection of the power generating water turbine 9 is made by determining the generating capacity (volts, amperes, watts) of the generator, determining the size of the power generating water turbine 9, and also determining the diameter of the inlet of the power generating water turbine 9. Then, by taking into consideration the water pressure, water volume, water flow, flow velocity, etc. of the water conveyance pipe 8 (the length is determined by hydraulic calculations required for the power generating water turbine 9 to turn the water wheel), the diameter of the outlet of the upper water tank 6 and the opening / closing valve (gate, ball valve, etc.) 19 can be easily selected (calculation that takes into account cases where the inlet of the power generating water turbine 9 is an irregular pipe).

[0016] The water flow tube rotating water wheel 10 is directly connected to the outer periphery of the water flow tube 2, and the water for hydroelectric power generation after hydroelectric power generation is discharged from the outlet of the power generating water wheel (turbine) 9 at an angle, and the angle is determined by calculations so that the water pressure, water volume, water flow, and flow velocity are the maximum amount that pushes the water wheel without resistance when turning the water flow tube rotating water wheel 10, and the rotation speed of the water flow tube 2 is maintained, and the number of water wheel impellers of the water flow tube rotating water wheel 10 is determined by the amount of water for hydroelectric power generation discharged from the outlet of the power generating water wheel (turbine) 9 for the next power generation. The amount of water discharged up to the outlet of the water wheel (turbine) 9 is calculated, and the number of impellers is calculated (the dimensions of each interval of the radially installed power generating water wheels (turbines) 9 are known, and the amount of water at each interval is known, and the number of impellers can be calculated from the difference in the amount of water from the water flow barrel rotating water wheel 10 to the drain pipe 11 and the amount of water at each interval of the power generating water wheel (turbine) 9 ([Figure 1-2] shows a plan view of the outlet of the power generating water wheel (turbine) 9, the impeller of the water flow barrel rotating water wheel 10, and the inlet of the water conduit 10).

[0017] The inlet of the drain pipe 11 is angled so as not to interfere with the drainage speed or discharge volume of the water flow barrel rotating water wheel 10, and is installed at a location selected that is efficient for the water to flow into the lower water tank 1 and suck up for hydroelectric power generation in the water flow barrel 2, and the discharge angle is calculated. The drain pipe 11 turns the impeller of the water flow barrel rotating water wheel 10, and then flows into the drain pipe 11, after which it is sprayed from the bottom of the lower water storage tank 1 at an angle (parallel to the angle of the spiral plate (vane 3)) and flows into the water volume barrel 2, but is installed so that it is directly sucked into the wall of the water flow barrel 2 and the spiral plate (vane) 3 fixed to the central axis 4 of the water flow barrel, and a position is calculated that can prevent excessive water flow, and the burden on the vortex water flow prevention plate of the lower water storage tank 1 is reduced (the angle and arrangement that minimizes the inflow resistance of the spiral plate (vane) 3 [shown in Figure 1-3]).

[0018] The injection / drainage dual-use pipe 12 is a common pipe for both the refill water tank 13, the excess water tank 15, and the lower water storage tank 1 inlet 17. When the water flows into the lower water storage tank 1, the injection / drainage dual-use pipe on / off valve (lower water storage tank 1 inlet) 20 is opened and the injection / drainage dual-use pipe on / off valve (top of excess water storage tank 15) 21 is closed to fill the lower water storage tank 1 and prevent the excess water storage tank 15 from flowing in. When the water flows in from the lower water storage tank 1 inlet 17, the injection / drainage dual-use pipe on / off valve (top of excess water storage tank 15) 21 is closed. (The inlet 20 of the excess water tank 1 is closed except when water is flowing in.) When using the excess water tank 15, if the water level for hydroelectric power generation exceeds the water level in the lower water tank 1, the valve for the inlet / outlet pipe (top of the excess water tank 15) 21 at the top of the excess water tank 15 can be left open to allow water to flow into the excess water tank 15. When using the refill water tank 13, the valve for the inlet / outlet pipe (top of the excess water tank 15) 21 at the top of the excess water tank 15 can be either open or closed, but the excess water tank 15 must be filled with water for hydroelectric power generation and the amount of water that can be poured into the refill water tank 13 must be met.)

[0019] The replenishment water tank 13 is a water tank that uses a replenishment water tank suction pump 16 to fill the tank with water from the excess water tank 15, and strives to maintain the amount of water for hydroelectric power generation so that the water level in the lower water tank 1 does not drop to a dangerous level. The tank area of ​​the replenishment water tank 13 and the area of ​​the excess water tank 15 are calculated from the capacity of the lower water tank 1 (taking into account the evaporation and scattering of the water for hydroelectric power generation in the lower water tank 1).

[0020] The water flow cylinder auxiliary power motor 14 rotates the water flow cylinder 2 during the initial operation of the hydroelectric power generation water circulation activity, and the water for hydroelectric power generation is stored in the upper water tank 6 and flows into the water conduit 8, turning the power generation water wheel (turbine) 9. The reverse siphon action ends at the inlet of the water flow cylinder rotation water wheel 10, and after flowing into the drain pipe 11, it returns to the lower water tank 1 and the power generation water circulation activity is repeated again. Once the circulation activity is normal, the water flow cylinder auxiliary power motor 14 switches over to the generator. If the water flow cylinder 2 experiences insufficient rotation speed or power generation capacity due to maintenance work, the water flow cylinder auxiliary power motor 14 will make up for the insufficient rotation capacity of the water flow cylinder rotation water wheel 10, and the power for the water flow cylinder auxiliary power motor 14 during the initial operation of the circulation power generation is supplied by other power sources (power from power generation facilities such as storage batteries, hydroelectric, thermal, and nuclear power), and the drive of the water flow cylinder auxiliary power motor 14 is the wheel drive that rotates in close contact with the water flow cylinder rotation water wheel 10.

[0021] If the water for hydroelectric power generation in the lower water reservoir 1 becomes excessive (overflows), the water for hydroelectric power generation in the lower water reservoir 1 is immediately injected into the excess water tank 15 through the dual-purpose drainage pipe 12 to stabilize the water level (the amount of water in the excess water tank 15 is the water source for the replenishment water tank 13, and the excess amount is calculated from the capacity of the replenishment water tank 13, the excess amount of water for hydroelectric power generation, and the amount that fills the capacity of the replenishment water tank 13).

[0022] The replenishment water tank suction pump 16 is a replenishment water tank suction pump 16 for pumping water for hydroelectric power generation from the excess water layer 15 into the replenishment water tank 13.

[0023] The lower water tank inlet 17 is the inlet for the water used for power generation in the lower water tank 1 (the water for power generation is secured by providing a water intake pipe or water intake channel from a water source such as a river, pond, or lake).

[0024] On-off valves (gate, ball valve, etc.) 19 are installed at the inlet and outlet of the water conveyance pipe 8, and by closing the upper on-off valve (gate, ball valve, etc.) 19, maintenance such as replacing the water conveyance pipe 8 or rewinding or replacing the generator coil can be performed without shutting down the entire power generation facility, allowing for concentrated work such as stopping the generator in a single section and performing part replacement work. During initial power generation operation, the on-off valve (gate, ball valve, etc.) 19 at the bottom, located just before the power generation water wheel (turbine) 9, is closed, the water flow tube 2 is operated, the upper water storage 6 and water conveyance pipe 8 are filled with water, and the lower on-off valve (gate, ball valve, etc.) 19 is opened, allowing for quick action in the hydroelectric power generation water circulation activity (the on-off valve (gate, ball valve, etc.) 19 should have the same diameter as the water conveyance pipe, and should be designed so that there is no change in the flow of the power generation water, and changes in air bubbles, flow rate, flow velocity, water pressure, etc. can be accommodated in the water flow within the valve structure, minimizing time loss).

[0025] The selection of generators is based on the total number of generators calculated by converting the performance of each generator (volts, amperes, watts) from the total generating capacity of the power generation facility.

[0026] Water for hydroelectric power generation is guided from the lower water storage tank 1 to the upper water storage tank 6 by the centrifugal force generated by the rotation of the water storage suction pump, which is composed of a spiral plate (vane) 3 built into the water flow cylinder 2. The water flows into the upper water storage tank 6, where air is removed by the air valve 7, and the water flows down the water conveyance pipe 8 due to the reverse siphoning motion from the upper water storage tank 6. This turns the power generating water wheel (turbine) 9, where the reverse siphoning motion ends at the inlet of the water flow cylinder rotating water wheel 10, where it flows down naturally to the water flow cylinder rotating water wheel 10, then reaches the lower water storage tank 1 through the drain pipe 11, where it flows into the water flow cylinder 2 again, and then flows into the upper water storage tank 6 due to the centrifugal force generated by the spiral plate 3, where the reverse siphoning motion is repeated.

[0027] As a means of amplifying the discharge water pressure, water volume, water flow and flow rate of a water storage suction pump with a structure consisting of a spiral plate (vane) 3 built into the water flow tube 2, the upper cylindrical shape of the water flow tube 2 facing the upper water tank 6 is made conical, making the area of ​​the suction part narrower than the inlet area on the lower water tank 1 side, and even with the same rotation, the upper part becomes narrower, which increases the discharge water pressure, water flow and flow rate, and the flow rate inside the water conveyance pipe 8 from the upper water tank 6 increases, and the water pressure, water flow and flow rate also increase, increasing the kinetic capacity of the reverse siphon movement, which flows down faster than natural flow movement, but also increasing the water pressure, water volume, water flow and flow rate (as the flow rate increases, the flow rate also increases).

[0028] Based on what has been stated in

[0005] to

[0027] , calculations are made and drawings are drawn, but the first thing to do is to determine the capacity of the voltage, current, amount of power, etc. required by the power generation equipment, and once the voltage, current, and amount of power are determined, the output voltage, current, and amount of power required for one generator are known, and then the number of generators required and the number of generators required are determined, and the amount of water for hydroelectric power generation in the upper water tank 6 (the surface area of ​​one generator can be calculated using the diameter of the inlet of the power generation water turbine 9, and the total number of power generation water turbines 9 to be used can be calculated by multiplying this by the total number of power generation water turbines 9) is determined, and the inflow area is known, and the upper area of ​​the water flow tube 2 and the diameter of the circle are determined, and the water flow Once the area of ​​the bottom of tube 2 (the amount of water that can be discharged in excess of the required amount in terms of water pressure, water volume, water flow, and flow velocity discharged to the top) and diameter are known, the shape of water conduit 8 (the length is determined by calculating the dynamic water pressure and static water pressure required to turn the power generating water wheel (turbine) 9) can also be determined. The amount of water for power generation discharged from power generating water wheel (turbine) 9 to power flow tube rotating water wheel 10 becomes clear, the number of impellers can be determined, and the amount of water for power generation from drainage pipe 11 until it flows into water flow tube 2 can be calculated. Once the shape of water flow tube 2 is determined, the total amount of water for circulation can be calculated, so the volume of lower water storage tank 1 can also be determined, and the replenishment water tank 13 and excess water water tank 15 can be determined and drawings can be drawn. [Effects of the Invention]

[0029] This method of circulation involves a water suction pump consisting of a lower water tank 1, a spiral plate (blade) 3 inside a water flow tube 2, an upper water tank 6, a water conveyance pipe 8, a generator water wheel (turbine) 9, a water flow tube rotating water wheel 10, and a drainage pipe 11, with a fixed amount of water for hydroelectric power generation circulating through the pump.The water for hydroelectric power generation is not discharged, and by securing the amount of water required for operation, hydroelectric power generation can be carried out anywhere.

[0030] This invention can contribute to reducing CO2 emissions by replacing fuel used in thermal power generation with water in the recycling of water used for hydroelectric power generation. Unlike previous hydroelectric power generation methods that cause environmental destruction such as waste from nuclear power generation, this invention recycles water used for hydroelectric power generation and eliminates the geographical disadvantages caused by hydroelectric power generation. [Brief explanation of the drawings]

[0031] [Figure 1] [Figure 1-1] [Figure 1-2] [Figure 1-3] [Figure 1], [Figure 1-1], [Figure 1-2], and [Figure 1-3] are cross-sectional diagrams of a method described based on the circulating form of water for hydroelectric power generation. Mode for carrying out the invention

[0032] Drawings were created in accordance with the data calculated using the methods listed in

[0005] to

[0028] , and drawings were created showing the hydroelectric power generation water flowing into a water storage suction pump consisting of a lower water tank 1 and a water flow tube 2 with a built-in spiral plate (vane) 3. The water is guided by the centrifugal force generated by the rotational motion and reaches the upper water tank 6, where air bubbles are removed by an air valve 7 so that the upper part becomes a vacuum. The water then flows down a water conduit 8 and into a power generating water wheel (turbine) 9, and after the power generating water wheel (turbine) 9 has finished rotating the generator, the water pressure, water volume, water flow, and flow rate of the hydroelectric power generation water are strengthened, and the water flows into the water flow tube rotating water wheel 10, which has the number of impellers adjusted, and all back siphoning motion is completed before the rotational motion of the water flow tube rotating water wheel 10, and the hydroelectric power generation water flows down naturally to the water flow tube rotating water wheel 10 and drainage pipe 11, where it flows into the lower water tank 1. This shows the circulation activity of the hydroelectric power generation water and production drawings were created.

[0033] Once the overall capacity of the power generation equipment, such as voltage, current, and power, is determined, the required output voltage, current, and power per generator are known, and the number of generators is clarified. Then, taking into account the inflow volume during operation of the lower water tank 1 and the water level during inactivity, the water flow cylinder 2 and the bottom area of ​​the lower water tank 1 and the dimensions of the lower water tank 1 vortex water prevention plate 18, which is connected to the lower water tank 1 and is installed after calculating the dimensions to prevent contact with the water flow cylinder 2, are installed. The water flow tube 2 is a water storage suction pump with a structure that prevents the water for hydroelectric power generation from scattering and is composed of a built-in spiral plate (vane) 3. The required water for hydroelectric power generation is pushed up into the upper water tank 6, and the capacity to be suctioned is determined. The capacity of the outlet and the diameter of the inlet of the water flow tube 2 can also be calculated, and the water pressure, water volume, water flow, and flow velocity of the water for power generation flowing down to the power generation water wheel (turbine) 9 connected to the water conduit 8 installed radially from the upper water tank 6 are also determined, and the required downflow water pressure is also determined. Therefore, the diameter and length of the water conduit 8 are also known at the same time, as is the length of the water flow tube 2. The shape and internal dimensions of the upper water tank 6 are also known at the same time, and the installation location of the air valve 7 is also known. The power generation water discharged from the power generation water wheel (turbine) 9 flows into the power generation water wheel 10. The number of impellers of the power generation water wheel 10 is determined by the amount of power generation water discharged from the outlet of the power generation water wheel (turbine) 9. The quantity of impellers is calculated and selected (the dimensions of each interval of the radially arranged hydroelectric turbines 9 are known, and the amount of water at each interval is known, and the number of impellers can be calculated from the difference in the amount of water at each interval of the power generating turbines (turbines) 9 from the water flow barrel rotating turbine 10 to the drain pipe 11). ([Figure 1-2] shows a plan view of the outlet of the power generating turbine 9, the impeller of the water flow barrel rotating turbine 10, and the inlet of the drain pipe 111). The power generating water for the water flow barrel rotating turbine is drained. After flowing into the pipe 11, the water is installed at an appropriate location and angle (shown in [Figure 1-3]) so that it flows into the spiral plate (blade) 3 built into the water flow tube 2 of the lower water tank 1, and circulation activity is carried out. An illustration of the shape and production drawings are created. [Industrial Applicability]

[0034] There are fewer geographical constraints on hydroelectric power generation, making it possible to build hydroelectric power plants in densely populated areas such as urban areas, there are fewer constraints on securing water sources, there are no fuel costs, hydroelectric power plants can be built with the same structure, hydroelectric power plants can be networked smoothly, thermal power generation is no longer necessary, CO2 emissions are eliminated, equipment inspections at power plants can be standardized, and unlike nuclear power generation methods that cause environmental destruction such as waste, hydroelectric power generation does not destroy the natural environment such as rivers, valleys, forests, and settlements, making it useful for preserving the local area.

When starting up, the upper opening / closing valves (gate, ball valve, etc.) 19 of the power generating water turbine 9 are closed, and water is poured up to the water conveyance pipe 8. Once there are no air bubbles and the water is full, the opening / closing valves (gate, ball valve, etc.) 19 at the top of the power generating water turbine 9 arranged radially are opened, allowing for quick action and start of the circulation of the water for power generation. The electricity capacity can also be secured quickly (when the water flow cylinder auxiliary power motor 14 is operated with all the on-off valves (gate ball valves, etc.) 19 open, the hydroelectric power generation water flowing down from the upper water tank 6 flows down the water conduit 8, and then the rotational movement of the power generating water wheel (turbine) 9 will be such that the water pressure, water volume, water flow and flow velocity of the hydroelectric power generation water will be insufficient, resulting in an insufficient inflow, and the power generating water in the water conduit 8 and the power generating water wheel (turbine) 9 will not be filled to capacity, resulting in the hydroelectric power generation water containing air bubbles, and a large amount of hydroelectric power generation water will have to be released before the air bubbles are removed and the hydroelectric power generation water is full, and normal rotation of the power generating water wheel (turbine) 9 will result in normal rotation of the generator, so it will take time to secure the standard power generation capacity, so be sure to close the on-off valves (gate ball valves, etc.) 19 above the power generating water wheel (turbine) 9).
