Description

Green and environmentally friendly hydropower generation system Technical Field

[0001] This disclosure relates to the field of hydropower technology, and more specifically to a green and environmentally friendly hydropower generation system. Prior Technology

[0002] Traditional urban water supply methods typically employ the following two schemes:

[0003] (1) Direct water supply: The government reservoir supplies water directly to users of low-rise buildings through closed water pipes, with a water head and pressure of approximately 60-100 meters.

[0004] (2) Indirect water supply: The government supplies water from the reservoir to the ground water tank of the building through closed water pipes, and then pumps it to the top rooftop water tank through the water pump in the building. The water is then supplied to users through closed water pipes using the pressure difference between high and low pressure. The highest pressure difference can exceed 100 meters of water head pressure.

[0005] To prevent damage to pipes and related facilities caused by excessive water pressure, resulting in property loss, various methods have traditionally been used, including installing pressure-reducing valves to reduce excess water pressure inside the pipes. However, the energy contained in the water pressure reduced by these valves is completely wasted and not effectively utilized.

[0006] Therefore, in view of the shortcomings of existing technologies, how to provide a green and environmentally friendly hydropower generation system is a problem that those with knowledge in this field urgently need to solve. Summary of the Invention

[0007] In view of this, this disclosure provides a green and environmentally friendly water energy power generation system that can be installed on the rooftop or ground of a building. It utilizes the water energy generated from daily water use to convert the pressure energy that would otherwise be wasted into electrical energy. The generated current can be used in public corridors, staircases, and various green and smart power supply facilities, thereby meeting the environmental protection and carbon emission reduction requirements of green cities.

[0027] The technical solutions of the embodiments disclosed herein will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without making any innovative efforts are within the scope of protection of this disclosure.

[0028] This disclosure embodiment presents a green and environmentally friendly hydropower generation system, including: an external water pipe connection device 2, a ball valve 3, a water turbine 5, an energy generator 6, an energy stabilization device, and a power output controller 10;

[0029] The ball valve 3 is installed on the external water pipe connection device 2 and is used to control the flow of water into the main unit housing;

[0030] Water flows through the external water pipe connection device 2 into the water turbine 5;

[0031] The external water pipe connection device 2 is connected to the main water pipe with pressure differential;

[0032] The water turbine 5 receives water with pressure difference delivered by the ball valve 3. The water flow impacts the blades of the water turbine 5, causing them to rotate and generate mechanical energy.

[0033] The water turbine 5 is connected to the power generator 6 via a transmission connection;

[0034] The power stabilization device is connected to the power generator 6;

[0035] The power stabilization device is connected to the power output controller 10.

[0036] Specifically, it also includes: a main unit housing 1, which comprises an upper main unit housing unit and a lower main unit housing unit;

[0037] The power stabilization device and power output controller are integrated within the upper main unit.

[0038] The lower main housing unit integrates the external water pipe connection device 2, ball valve 3, pressure detector 4, water turbine 5, and power generator 6.

[0039] Specifically, the main unit casing serves as the mounting carrier for the integrated system components. It is connected to the main water pipe bypass via the external water pipe connection device 2, and the internal components are fixed to ensure stable transmission and circuit connection between the components.

[0040] Specifically, it also includes: pressure detector 4 and detector, which are integrated in the lower host housing unit.

[0041] The pressure detector 4 is installed on the external water pipe connection device 2.

[0042] Specifically, the power stabilization device includes: a power converter 7, a power transformer 8, and a voltage regulator 9; the power generator 6 is connected to the power transformer 8;

[0043] The power transformer 8 supplies voltage to the voltage stabilizer and energy storage device 9;

[0044] The voltage regulator energy storage device 9 is connected to the power output controller 10.

[0045] Specifically, the external water pipe connection device is equipped with a three-way valve or a bypass insert water pipe, and the three-way valve and the bypass insert water pipe are connected to the inlet / outlet branch pipes of the external water pipe connection device 2.

[0046] Specifically, it also includes: an alarm system, which automatically switches back to the original main water supply when a system malfunction or efficiency decline is detected, and the alarm system automatically issues a maintenance notification.

[0047] Specifically, the connection end between the three-way valve and the bypass cartridge water pipe is equipped with a union or flange.

[0048] Specifically, the external water pipe connection device 2 connects to the bypass plug-in through the three-way valve on the main water pipe, and the water flow is taken from the main water pipe in front of the middle and lower floors of the building or the water storage tank through the main water pipe with pressure difference.

[0049] The inlet / outlet branch pipes of the external water pipe connection device are the inlet for water to enter the unit and the outlet for water to flow out.

[0050] The ball valve 3 is located in the inlet / outlet section of the external water pipe connection device 2, connected in series between the pressure detector 4 and the turbine 5, and is used to control the flow of water. It is the switching component for water to enter the turbine unit.

[0051] The turbine 5 receives water with pressure differential delivered by the ball valve 3, and generates mechanical energy by impacting the blades with the water flow. It is connected to the power generator 6 via magnetic coupling, and the mechanical energy is transferred to the power generator 6.

[0052] The power generator 6 receives the mechanical energy transmitted from the water turbine 5 and converts it into raw electrical energy. The power generator 6 is connected to the power converter 7 and transmits the raw electrical energy to the power converter 7.

[0053] The power converter 7 receives the raw electrical energy from the power generator 6 and performs AC / DC conversion. The power converter 7 is connected to the power transformer 8 and transmits the converted electrical energy to the power transformer 8.

[0054] The power transformer 8 receives the electrical energy processed by the power converter 7 and converts it into a standard voltage to meet the needs of the building's power grid. The power transformer 8 is connected to the voltage storage device 9 to transmit standard voltage electrical energy.

[0055] The voltage stabilizer 9 receives standard voltage electrical energy from the power transformer 8, and stores and stabilizes the voltage to cope with current instability caused by fluctuations in water flow. The voltage stabilizer 9 is connected to the power output controller 10 and delivers the stabilized electrical energy to the power output controller 10.

[0056] The power output controller 10 receives stable electrical energy from the voltage regulator and energy storage unit 9, performs output control, connects to the building's power grid, or directly supplies power to equipment such as lighting in the building's public areas, fire escape indicator lights, and burglar detectors. The electrical energy can also be stored in the lithium battery pack system.

[0057] In one specific embodiment disclosed herein, a water-powered electricity generation system utilizing water supply pipes attached to the interior of high-rise buildings, namely an Integrated Vertical Pipe Hydro System (IVPHS), uses the residual pressure of the main water pipe to generate electricity (micro-hydro power in buildings), which is a very promising energy-saving and carbon-reduction solution. Traditional high-rise building water supply systems install pressure reducing valves (PRVs) on lower floors to prevent excessive water pressure from damaging the pipes.

[0058] The principle of this disclosed embodiment is to convert the water pressure energy that would otherwise be wasted into electrical energy by connecting it in parallel with the main water pipe pressure reducing valve or installing it independently.

[0059] To facilitate installation and maintenance, this disclosed embodiment adopts a modular design. The built-in turbine unit uses a water turbine 5 that is highly adaptable to changes in water flow. It is most suitable for installation on the lower or middle floors of a building (where the pressure difference is greatest) or at the location of the main water pipe before entering the water storage tank. A three-way valve and a bypass plug-in are installed on the main water pipe, connecting to the inlet / outlet branch pipes of the internal / external water pipe connection device 2 of the main housing 1. The water flow with pressure difference drives the water turbine 5 and the power generator 6 through the ball valve 3 of the inlet / outlet section. The connection ends of the water pipes are equipped with union joints or flanges for easy disassembly and replacement. Even if the machine needs maintenance, the original water supply system can continue to operate without affecting the normal water supply. The power generator 6 is a generator, which uses a permanent magnet motor and is integrated inside the main housing 1. It is connected to the water turbine 5 through magnetic coupling transmission, achieving complete separation of water and electricity to avoid the risk of leakage. The generated electricity is converted from AC to DC by the power converter 7 and then converted to standard voltage power by the power transformer 8. Because the water flow will fluctuate with the user's water usage habits, the current must be output to the building's power grid through a dedicated voltage regulator 9 and power output controller 10.

[0060] Specifically, the external water pipe connection device 2 includes an inlet and an outlet, and the ball valve 3 includes an inlet ball valve and an outlet ball valve;

[0061] The system is also equipped with a pressure detector 4 and detectors, including an inlet water detector and an outlet water detector;

[0062] The pressure detector 4 is installed at the inlet of the external water pipe connection device 2. Based on the data detected by the pressure detector 4, when the system detects that the water pressure is normal but the generator speed is lower than normal, it is possible that there is a blockage in the pipe. The system will issue a water supply abnormality signal and automatically switch to the main water pipe supply state.

[0063] When the water pressure and flow rate are detected to be normal, but the generator's power output is lower than normal, the system will automatically issue a generator maintenance signal.

[0064] The key to this disclosed embodiment is that it does not affect the stability of the water supply and water quality of the original main water pipe design. The area in contact with water is made of 316L stainless steel, and the operation in a fully enclosed pipe ensures drinking water safety and resistance to corrosion and rust.

[0065] This disclosed embodiment relates to a hydroelectric power generation system that is conveniently installed on the rooftop or ground level within a building, utilizing the pressure differential kinetic energy of the daily water supply system to generate electricity. When a system fault or efficiency decline is detected, the system automatically switches back to the original main water supply pipe, and an alarm system automatically issues a maintenance notification. The electrical energy generated by the hydroelectric generator in this embodiment is stored in a lithium battery system, supplying power to lighting in public areas of the building, fire escape route indicator lights, or burglar alarms, etc. The design complies with standard building codes for water supply pipe diameters (DN50-DN200), enabling immediate use upon installation. It can be installed in various locations and scenarios, and construction and maintenance are simple. This system represents a green renewable energy power generation system that helps modern buildings achieve energy conservation and carbon reduction (ESG) goals.
