Description

A multifunctional, energy-saving, invisible, and high-efficiency power station Technical Field

[0001] This invention relates to the field of power plant technology, specifically to a multifunctional, energy-saving, concealed, and highly efficient power plant. Background Technology

[0002] A power plant is a factory that converts various primary energy sources found in nature into electrical energy (secondary energy). Existing power plants utilize various power generation methods: thermal power plants (generating electricity from thermal power), hydropower plants (generating electricity from hydropower), and new energy power plants (generating electricity from solar (photovoltaics), wind power, and tidal power). Among these, hydropower is a technologically mature, environmentally friendly, and pollution-free renewable energy source. Existing hydropower plants typically utilize dams, water diversion tunnels, pressure basins, and pressure pipes to create a drop in elevation, generating potential energy. This potential energy drives turbines and generator units to generate electricity, converting the potential energy into mechanical energy, and then into electrical energy. However, traditional hydropower plants require careful consideration of geographical conditions during construction, have high requirements for site selection, high construction costs, and are inconvenient to install and use.

[0003] To address the aforementioned issues, existing patent application number 2024100337038 discloses a water energy recycling hydropower station system, including a power station base pool. A control cabinet, generator, turbine, and elevated water tank are fixedly installed on the top of the power station base pool via a suspension device. This power station system uses the elevated energy storage pool to drive a high-efficiency water lifting device that does not require oil or electricity to lift water to the elevated water tank. The turbine in the elevated water tank then drives the generator to generate electricity. This effectively utilizes the potential energy of water to generate electricity without requiring external energy sources such as oil, making it more environmentally friendly. Furthermore, the water is recycled within the energy storage pool for power generation.

[0004] The above scheme solves the limitation of existing hydropower stations that require special terrain by building a water tank, and the installation is more convenient. However, the above scheme often wastes some of the water's potential energy when starting power generation, and the utilization efficiency of water potential energy is not high.

[0005] To address the aforementioned issues, the applicant, in conjunction with the above solutions, researched and designed a multifunctional, energy-saving, concealed, and highly efficient power station. Summary of the Invention

[0006] The technical problem this invention aims to solve is to overcome the shortcomings of the aforementioned technologies and provide a multifunctional, energy-saving, concealed, and efficient power station. The purpose is to vertically install a generator room below a water tank, housing multiple multifunctional power units consisting of five components. The five components include: a first device—a multi-bladed directional spiral water turbine; a second device—a direction-changing device; and third, fourth, and fifth devices—all water turbines. The core of the multifunctional power unit utilizes the high pressure created by the water tank to enter the water turbine power unit. Through the interaction of the water turbine and the high-pressure water tank, the water's potential energy is increased several times, generating powerful force to drive the generator. When the generator is overloaded, all ball valves on the water turbine power unit open, allowing water from the water tank to enter. If the generator and water turbine power unit are not rotating, the water will not penetrate deeply downwards and outwards, and the high-pressure water entering the water turbine power unit, with the assistance of the power unit, will cause the generator to rotate. Therefore, except when personnel close the valves, the generator rotates continuously and generates electricity, forming perpetual motion power generation. The "invisible" feature involves prefabricating a cover plate on top of the pool, placing a layer of soil on top, and planting various plants on top, effectively concealing it. The power storage capacity is astonishing; the power station can naturally store as much electricity as it generates—this is the core of the multifunctional, energy-saving, invisible, and highly efficient power station.

[0007] The technical problem to be solved by this invention is to overcome the defects of the above-mentioned technologies and provide a multifunctional, energy-saving, invisible, and efficient power station. The purpose is to install a multifunctional power unit below the water tank, namely a multi-bladed spiral directional water turbine, a guide device, a first water turbine, a second water turbine, and a third water turbine. Driven by the potential energy of the water, the spiral central shaft and the rotating shaft rotate, and then output power through the guide device. Multiple multifunctional power units work together to drive the generator set to generate electricity, so that the same amount of water can drive a larger generator to generate electricity, which greatly improves the utilization rate of water potential energy.

[0008] To solve the above-mentioned technical problems, the technical solution provided by the present invention is as follows: a multifunctional energy-saving, invisible and efficient power station, including a water tank, a generator room is arranged below the water tank, a circulating water channel is arranged below the generator room, a number of generator sets are placed in the generator room, and a return flow device is arranged on both sides of the circulating water channel.

[0009] The generator room is equipped with several multi-functional power units. Each multi-functional power unit includes a multi-bladed spiral directional water turbine, a guide device, a first water turbine, a second water turbine, and a third water turbine arranged coaxially. The guide device is connected to the bottom of the multi-bladed spiral directional water turbine.

[0010] The guiding device includes a frame and a bevel gear disposed within the frame. The bevel gear includes an upper gear, a lower gear, a left gear, and a right gear disposed on the top, bottom, left, and right sides. The upper gear is driven and connected to a multi-bladed spiral directional water turbine. The lower gear is driven and connected to a first water turbine, a second water turbine, and a third water turbine. The left gear and the right gear are coaxially connected to an output shaft. The other end of the output shaft is connected to a generator, which is placed in a generator room.

[0011] Furthermore, the multi-bladed spiral directional water turbine includes a spiral central shaft and a spiral sleeve sleeved on the spiral central shaft. A spiral disc is provided on the outer ring of the spiral sleeve, and multiple spiral blades are provided on the outer ring of the spiral disc. The spiral disc is fixedly connected to the spiral central shaft, and the lower end of the spiral central shaft is coaxially fixedly connected to the upper gear.

[0012] Furthermore, the first, second, and third water turbines each include a rotating shaft and a sleeve fitted on the rotating shaft. A turntable is provided on the outer ring of the sleeve, and multiple blades are provided on the outer ring of the turntable. The sleeve is fixedly connected to the rotating shaft, and the two ends of the rotating shaft are connected by a coupling. The upper end of the rotating shaft of the first water turbine is coaxially and fixedly connected to the lower gear.

[0013] Furthermore, the multi-bladed spiral directional water turbine is provided with a spiral water inlet at its upper end. The spiral water inlet consists of multiple spiral water inlets arranged in a ring array. A shut-off ball valve is provided at its upper end to cooperate with the spiral water inlet. The spiral water inlet is configured to cooperate with the spiral blades. Multiple sets of spiral blades are arranged along the central axis of the spiral. Each set of spiral blades consists of multiple spiral blades arranged in a ring array. The spiral blades are spiral-shaped, and adjacent spiral blades are arranged in opposite directions.

[0014] Furthermore, the first waterwheel is provided with a first water inlet at its upper end, and the first water inlet is arranged in a ring array of multiple such inlets; the second waterwheel is provided with a second water inlet at its upper end, and the second water inlet is arranged in a ring array of multiple such inlets; and the third waterwheel is provided with a third water inlet at its upper end.

[0015] Furthermore, the blades are arranged in multiple groups along the rotation axis, and each group of blades is arranged in a circular array. The blades are arranged horizontally and are configured in conjunction with the first water inlet, the second water inlet, and the third water inlet.

[0016] Furthermore, the water return device delivers water into the water tank through a water delivery pipe. The water delivery pipe is divided into multiple sections, and a water return device is installed below each section of the water delivery pipe. There are multiple multi-functional power units, and each multi-functional power unit is connected to a circulating branch water channel below it. The other end of each of the multiple circulating branch water channels is connected to a circulating central water channel, and the other end of each of the multiple circulating central water channels is connected to a circulating water channel.

[0017] Furthermore, the output shaft of each multi-functional power unit, connected to the right gear, is connected to the output shaft of the adjacent multi-functional power unit, connected to the left gear, via a coupling. The output shafts of multiple multi-functional power units are connected end-to-end, and the output shaft of the last multi-functional power unit is connected to the generator drive.

[0018] The advantages of this invention compared to the prior art are:

[0019] 1) By driving the spiral central shaft to rotate through the spiral blades on the multi-functional power machine, and driving the rotating shaft to rotate through the blades, the multi-bladed spiral directional water turbine, the first water turbine, the second water turbine, and the third water turbine set up at the top and bottom greatly improve the utilization rate of water potential energy; the output shafts at the lower ends of multiple multi-functional power machines are connected end to end to form a linkage, which can drive a generator with a larger power output to generate electricity, and the utilization efficiency of water potential energy is high.

[0020] 2) The first, second, and third water turbines, arranged in three layers (upper, middle, and lower), have blades that are respectively matched with the first, second, and third water inlets. This ensures that water will not flow downwards or outwards through the turbine before the blades rotate, thus avoiding the waste of water potential energy and further improving the utilization rate of water potential energy.

[0021] Power generation can be achieved by constructing water tanks and circulating waterways, utilizing the potential energy of water. It requires a small land area, has low site selection requirements, can be built in resource-poor areas, and is not limited by terrain.

[0022] 4) It converts water potential energy into mechanical energy, and then mechanical energy into electrical energy, without polluting the environment and avoiding damage to the environment. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in the present invention according to the specific circumstances.

[0036] Example 1:

[0037] Referring to the attached drawings, a multifunctional energy-saving, invisible, and efficient power station includes a water tank 1, a generator room 2 located below the water tank 1, a circulating water channel 3 located below the generator room 2, a number of generator sets placed inside the generator room 2, and return flow devices 301 located on both sides of the circulating water channel 3.

[0038] The generator room 2 is equipped with several multi-functional power units. Each multi-functional power unit includes a multi-bladed spiral directional water turbine 5, a guide device 9, a first water turbine 6, a second water turbine 7, and a third water turbine 8, all arranged coaxially. The guide device 9 is connected to the bottom of the multi-bladed spiral directional water turbine 5.

[0039] The guiding device 9 includes a frame 901 and a bevel gear disposed within the frame 901. The bevel gear includes an upper gear 902, a lower gear 903, a left gear 904, and a right gear 905 disposed on the upper, lower, left, and right sides. The upper gear 902 is connected to the multi-bladed spiral directional water turbine 5. The lower gear 903 is connected to the first water turbine 6, the second water turbine 7, and the third water turbine 8. The left gear 904 and the right gear 905 are both coaxially connected to an output shaft 906. The other end of the output shaft 906 is connected to a generator 10, which is placed inside the generator room 2.

[0040] In a preferred embodiment, the multi-bladed spiral directional water turbine 5 includes a spiral central shaft 501 and a spiral sleeve 502 sleeved on the spiral central shaft 501. A spiral disc 503 is provided on the outer ring of the spiral sleeve 502, and a plurality of spiral blades 504 are provided on the outer ring of the spiral disc 503. The spiral disc 503 is fixedly connected to the spiral central shaft 501, and the lower end of the spiral central shaft 501 is coaxially fixedly connected to the upper gear 902.

[0041] In a preferred embodiment, the multi-bladed spiral directional water turbine 5 is provided with a spiral inlet 201 at its upper end. The spiral inlets 201 are arranged in a ring array, and a shut-off ball valve 202 is provided at its upper end to cooperate with them. The spiral inlets 201 are cooperated with the spiral blades 504. The spiral blades 504 are arranged in multiple sets along the spiral central axis 501. Each set of spiral blades 504 is arranged in a ring array. The spiral blades 504 are spiral in shape, and adjacent spiral blades 504 are arranged in opposite directions.

[0042] In practice, after opening the shut-off ball valve, the water in the pool enters the multi-functional power unit through the ball valve. The lower end of the multi-functional power unit connects directly to the underground circulating water channel through the outlet. The two ends of the circulating water channel are connected to the pool through a return flow device, which repeatedly circulates the water to generate electricity. The return flow device is a multi-functional energy-saving water pump. The potential energy of the water drives the spiral blades to rotate, which in turn drives the spiral sleeve to rotate. The spiral sleeve drives the spiral central shaft to rotate, which in turn drives the upper gear to rotate. The upper gear, through gear meshing, drives the left and right gears to rotate, which in turn drives the output shaft to rotate, thus driving the generator to operate and generate electricity.

[0043] In a preferred embodiment, the first waterwheel 6, the second waterwheel 7, and the third waterwheel 8 each include a rotating shaft 601 and a sleeve 602 fitted onto the rotating shaft 601. A turntable 603 is provided on the outer ring of the sleeve 602, and multiple blades 604 are provided on the outer ring of the turntable 603. The sleeve 602 is fixedly connected to the rotating shaft 601, and the two ends of the rotating shaft 601 are connected by a coupling. The upper end of the rotating shaft 601 of the first waterwheel 6 is coaxially and fixedly connected to the lower gear 903.

[0044] In a preferred embodiment, the first water turbine 6 is provided with a first water inlet 203 at its upper end, and the first water inlet 203 is arranged in a ring array of multiple units; the second water turbine 7 is provided with a second water inlet 204 at its upper end, and the second water inlet 204 is arranged in a ring array of multiple units; and the third water turbine 8 is provided with a third water inlet 205 at its upper end.

[0045] In a preferred embodiment, the blades 604 are arranged in multiple groups along the axial direction of the rotation axis 601. Each group of blades 604 consists of multiple blades arranged in a circular array. The blades 604 are arranged horizontally and are configured in conjunction with the first water inlet 203, the second water inlet 204, and the third water inlet 205.

[0046] In specific implementation, the diameter of the second inlet is 20% larger than that of the first inlet, and the diameter of the third inlet is 20% larger than that of the second inlet. If water cannot drive the first water wheel to rotate through the first inlet, it will drive the second water wheel to rotate through the second inlet. The diameter of the second inlet 204 is 20% larger than that of the first inlet 203, increasing the pressure on the second water wheel and thus driving it to rotate. If the second water wheel still cannot be driven, water will drive it to rotate through the third inlet. The diameter of the third inlet is 20% larger than that of the second inlet, further increasing the pressure on the third water wheel and thus driving it to rotate. This causes the sleeve to rotate, driving the rotating shaft to rotate. A seal is installed between the blades and the third inlet; if the third inlet cannot be driven to rotate, water will not flow out, effectively avoiding the waste of water potential energy when starting the water wheel.

[0047] In a preferred embodiment, the water return device 301 delivers water into the water tank through the water delivery pipe 4. The water delivery pipe 4 is divided into multiple sections, and a water return device 301 is installed below each section of the water delivery pipe 4. There are multiple multi-functional power units, and each multi-functional power unit is connected to a circulating branch water channel 11. The other end of each of the multiple circulating branch water channels 11 is connected to a circulating central water channel 12, and the other end of each of the multiple circulating central water channels 12 is connected to a circulating water channel 3.

[0048] In a preferred embodiment, the output shaft 906 connected to the right gear 905 in each of the multi-functional power machines is connected to the output shaft 906 connected to the left gear 904 in the adjacent multi-functional power machine via a coupling. The output shafts 906 of the multiple multi-functional power machines are connected end to end, and the output shaft 906 of the last multi-functional power machine is connected to the generator 10 via a transmission.

[0049] By adopting the above method, the power output from multiple blade-driven rotating shafts can be linked to form a combined force, which drives a high-power generator to generate electricity.

[0050] In practice, the left gear below the first multi-functional power unit is missing, the right gear drives the output shaft to rotate, the output shaft drives the left gear of the second multi-functional power unit to rotate, and so on, forming a linkage. The right gear of the last multi-functional power unit drives the output shaft to rotate, and the output shaft drives the generator to operate and generate electricity.

[0051] In a preferred embodiment, a hanging rail is provided on the top of the water tank 1, and a crane is provided on the hanging rail.

[0052] In a specific implementation of this invention, a hanging rail is installed at the top of the pool to facilitate the installation of the water wheel formed by the blades, turntable, sleeve, and rotating shaft of the multi-functional power machine. Each rotating shaft is connected end to end to form a large rotating shaft.

[0053] Inspection ports or installation ports are provided on the water delivery pipes, and an inspection passage is provided on one side of the water delivery pipes.

[0054] By constructing water tanks, the total installed capacity can be determined based on electricity demand. The top of the tanks is sealed with a cover plate, and then covered with a layer of soil. Various plants can be grown on top of the soil for effective concealment. These tanks can be built underground within one square kilometer or in mountainous areas, depending on demand. One 20,000-kilowatt generator unit can be installed every 50 square meters. Excluding roads and necessary equipment, 18,000 units can be installed per square kilometer. Based on 20,000 kilowatts per unit, the total installed capacity is 360 million kilowatts. In the same area, a total installed capacity of hundreds of billions of kilowatt-hours can be constructed without limit. The storage capacity is astonishing, and power can be output at any time. The storage capacity is close to the total installed capacity, achieving an optimal effect of natural electricity storage technology.

[0055] In practical construction, it is not recommended to build on arable land, as construction costs on arable land are relatively high and waste land resources. It can be built in areas without any resources. In this invention, the water in the pool is injected once and used permanently, eliminating the need for frequent water extraction from nearby areas, thus reducing construction costs.

[0056] In the specific implementation of this invention, the installation of the multi-functional power unit involves pre-embedding a flanged interface at the bottom of the water tank during construction. The ball valve connects to the interface, and the multi-bladed spiral directional water turbine cover plate has eight holes, each 5 cm long, with the upper end connected to the ball valve. The lowest outlet of the multi-functional power unit protrudes 30 cm and mates with a pre-drilled hole at the bottom of the generator room. During installation, it is directly inserted into the pre-drilled hole for a complete seal. The multi-functional power unit is placed directly on the floor and fixed in place by a grid frame at the top, middle, and bottom.

[0057] The generator room is equipped with several sets of generator sets, with 10 units in each set operating in tandem. Each multi-functional power unit is connected to a ball valve via a pre-embedded interface at the bottom of the pool during construction. The multi-bladed spiral directional water turbine cover plate has eight 5-cm long interfaces prefabricated to connect to the ball valve, which leads directly to the pool. The bottom end of the multi-functional power unit has a 30-cm long outlet hole prefabricated to connect directly to the circulating water channel.

[0058] The core of setting up a three-section power turbine is that, except when personnel shut down the power generation system, it will never stop. Even if the generator is overloaded, it will not stop rotating because the second turbine is semi-enclosed and the third turbine is fully enclosed. When the motor and power system stop, the water in the pool will not seep out through the power turbine because the third turbine is fully enclosed. Therefore, under the strong pressure of the pool, the power system and generator are forced to rotate by the assistance of the turbine with a diameter of more than 2 meters. This is the core of setting up a three-section power turbine.

[0059] The bottom of the generator room is equipped with a crisscrossing circulating water channel leading to both sides of the generator room. Multiple sets of multi-bladed, multi-functional, energy-saving water pumps return water to the water pool for repeated circulation and power generation.

[0060] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the present invention, such designs should fall within the protection scope of the present invention.
