Description

Technical Field

[0001] The invention relates to the technical field of power stations, and in particular to a multifunctional energy-saving invisible high-efficiency power station. Background Art

[0002] A power station is a factory that converts various primary energy sources stored in nature into electrical energy (secondary energy). Existing power plants have a variety of power generation methods: thermal power plants that rely on thermal power, hydroelectric power plants that rely on hydroelectric power, and new energy power plants that rely on solar energy (photovoltaic) and wind and tidal power. Among them, hydroelectric power is a very mature, environmentally friendly, pollution-free renewable energy. Existing hydroelectric power stations usually use water dams, water diversion tunnels, pressure forebays, and pressure pipes to form a drop to generate potential energy, which drives turbines and generator sets to generate electricity, converting potential energy into mechanical energy, and then converting mechanical energy into electrical energy. However, traditional hydropower stations need to consider factors such as geographical conditions during construction, have high requirements for construction sites, high construction costs, and are inconvenient to install and use.

[0003] In response to the above problems, the existing patent application number: 2024100337038 discloses a water energy circulation hydropower station system, including a power station base pool, on the top of which a control cabinet, a generator, a turbine, and a high-level water tank are fixedly installed through a suspension device. The power station system drives an efficient water-lifting equipment that does not require oil or electricity through a high-level energy storage tank to lift water to the high-level water tank, and then uses the turbine in the high-level water tank to drive the generator to generate electricity, effectively utilizing the potential energy of water to generate electricity without the need for external energy such as oil power generation, which is more environmentally friendly, and the water will be recycled in the energy storage tank for power generation.

[0004] The above scheme solves the limitation that the existing hydropower station needs to rely on special terrain by building a water pool, and the installation is more convenient. However, the above scheme often wastes part of the water potential energy when using the water potential energy to start power generation, and the utilization efficiency of the water potential energy is not high.

[0005] In response to the above problems, the applicant combined the above solutions and researched and designed a multifunctional energy-saving invisible high-efficiency power station. Summary of the invention

[0006] The technical problem to be solved by the present invention is to overcome the defects of the above-mentioned technology, and provide a multifunctional energy-saving invisible high-efficiency power station, the purpose of which is to vertically set a generator room under the pool, and set a plurality of multifunctional power machines composed of five parts in the generator room. The five parts include the first device: a multi-blade directional spiral water wheel, the second device: a change-of-direction device, and the third device, the fourth device, and the fifth device are all water wheels. The core of the multifunctional power machine is to use the pool to form high pressure to enter the water wheel power main machine, and through the water wheel main machine, the water in the high-pressure water pool is increased several times through the interaction of the water wheel main machine, forming a powerful power to drive the motor to rotate. When the generator is overloaded, all the ball valves of the water wheel main machine are opened, and the water in the pool enters the water wheel main machine; if the generator and the water wheel power machine do not rotate, the water will not penetrate deeply downward and outward, and the high-pressure water will enter the water wheel power machine. Under the help of the power machine, the generator is driven to rotate, so except for the personnel closing the valve, the generator is permanently and long-term uninterruptedly rotating to generate electricity, forming perpetual power generation. Invisibility means that a prefabricated cover plate is capped on the top of the pool, and a layer of soil is placed on it, and various plants can be planted, which can effectively be invisible. The power storage is amazing. The power station can naturally store as much electricity as it can generate. This is the core of the multifunctional energy-saving invisible and efficient power station.

The other end of the output shaft 906 is connected to the generator 10, and the generator 10 is placed in the generator room 2.

[0040] A preferred implementation method of this embodiment is that the multi-blade spiral directional water wheel 5 includes a spiral center shaft 501, a spiral sleeve 502 sleeved on the spiral center shaft 501, the outer ring of the spiral sleeve 502 is provided with a spiral turntable 503, the outer ring of the spiral turntable 503 is provided with a plurality of spiral blades 504, the spiral turntable 503 is fixedly connected to the spiral center shaft 501, and the lower end of the spiral center shaft 501 is coaxially fixedly connected to the upper gear 902.

[0041] A preferred implementation method of this embodiment is that a spiral water inlet 201 is provided at the upper end of the multi-blade spiral directional water wheel 5, and the spiral water inlet 201 is multiple and arranged in a circular array. A stop ball valve 202 cooperating therewith is provided at the upper end thereof, and the spiral water inlet 201 is arranged in cooperation with spiral blades 504, and the spiral blades 504 are arranged in multiple groups axially along the spiral center axis 501, and each group of the spiral blades 504 is multiple and arranged in a circular array, and the spiral blades 504 are spiral-shaped, and two adjacent spiral blades 504 are arranged in opposite directions.

[0042] In specific implementation, after the ball valve is opened, the water in the pool passes through the ball valve and enters the multifunctional power machine. The lower end of the multifunctional power machine directly connects to the underground circulating waterway through the water outlet. The two ends of the circulating waterway return the water to the pool through the reflux device for repeated circulation and power generation. The reflux device is a multifunctional energy-saving water pump. The potential energy of the water drives the spiral blades to rotate, the spiral blades drive the spiral casing to rotate, the spiral casing drives the spiral center shaft to rotate, the spiral center shaft drives the upper gear to rotate, the upper gear drives the left and right gears to rotate through the meshing of the gears, and then drives the output shaft to rotate, driving the generator to operate and generate electricity.

[0043] A preferred implementation manner of this embodiment is that the first water wheel 6, the second water wheel 7, and the third water wheel 8 all include a rotating shaft 601, a sleeve 602 sleeved on the rotating shaft 601, a turntable 603 is provided on the outer ring of the sleeve 602, a plurality of blades 604 are provided on the outer ring of the turntable 603, the sleeve 602 is fixedly connected to the rotating shaft 601, the rotating shaft 601 is connected head to tail through a coupling, and the upper end of the rotating shaft 601 of the first water wheel 6 is coaxially fixedly connected to the lower gear 903.

[0046] In specific implementation, the diameter of the second water inlet is 20% larger than that of the first water inlet, and the diameter of the third water inlet is 20% larger than that of the second water inlet. If the water cannot drive the first water wheel to rotate through the first water inlet, the water drives the second water wheel to rotate through the second water inlet. The diameter of the second water inlet 204 is 20% larger than that of the first water inlet 203, so that the pressure on the second water wheel increases, and the second water wheel can be driven to rotate; if the second water wheel still cannot be driven, the water drives the second water wheel to rotate through the third water inlet. The diameter of the third water inlet is 20% larger than that of the second water inlet, so that the pressure on the third water wheel is further increased, and the effect of driving the third water wheel to rotate can be achieved, so that the sleeve rotates and the rotating shaft rotates. A sealing arrangement is provided between the blade and the third water inlet. If the third water inlet cannot be driven to rotate, the water will not flow out, which effectively avoids the waste of water potential energy when starting the water wheel to rotate.

[0047] A preferred implementation method of this embodiment is that the return water device 301 delivers water into the pool through the water delivery pipe 4, the water delivery pipe 4 is divided into multiple sections, and a return water device 301 is arranged under each section of the water delivery pipe 4. There are multiple multifunctional power machines, and each of the multifunctional power machines is connected to a circulating branch waterway 11 below, and the other ends of multiple circulating branch waterways 11 are connected to a circulating middle waterway 12, and the other ends of multiple circulating middle waterways 12 are connected to a circulating waterway 3.

[0048] A preferred implementation method of this embodiment is that the output shaft 906 connected to the corresponding right gear 905 in each of the multifunctional power machines is connected to the output shaft 906 connected to the corresponding left gear 904 in the adjacent multifunctional power machine through a coupling, and the output shafts 906 of multiple multifunctional power machines are connected end to end, and the output shaft 906 of the last multifunctional power machine is connected to the generator 10 in transmission.

[0049] By adopting the above method, multiple blades can drive the rotating shaft to rotate and promote the power output of the output shaft to form a combined force, thereby driving the high-power generator to generate electricity.

[0050] During the specific implementation, the left gear under the first multifunctional power machine is missing, and the right gear drives the output shaft to rotate, and the output shaft drives the left gear of the second multifunctional power machine to rotate, and so on, forming a linkage. The right gear of the last multifunctional power machine drives the output shaft to rotate, and the output shaft drives the generator to operate to generate electricity.

[0051] A preferred implementation manner of this embodiment is that a hanging rail is provided on the top of the water pool 1, and a crane is provided on the hanging rail.

[0052] When the present invention is implemented, a hanging rail is arranged on the top of the pool to facilitate installation of a water wheel formed by blades, a rotating disk, a sleeve and a rotating shaft on the multifunctional power machine, and each rotating shaft is connected end to end to form a large rotating shaft.

[0053] An inspection port or installation port is arranged on the water delivery pipe, and an inspection passage is arranged on one side of the water delivery pipe.

[0054] By building a pool, the total installed capacity can be determined according to the power demand. The top of the pool is closed with a cover, and then covered with a soil layer. Various plants can be planted on the soil layer to effectively hide it. It can be built underground in one square kilometer or in the mountains according to demand. A 20,000-kilowatt generator set can be installed for every 50 square meters. 18,000 units can be installed in one square kilometer excluding the lanes and necessary equipment and facilities. Calculated at 20,000 kilowatts per unit, the total installed capacity is 360 million kilowatts. In the same area, the total installed capacity can be built to hundreds of billions of kilowatt-hours. It can be built endlessly, with amazing reserves and output at any time. The storage capacity is almost equal to the total installed capacity, achieving the best effect of natural storage of electricity technology.

[0055] When constructing, it is not recommended to build on arable land. The construction cost on arable land is relatively high, which wastes land resources. It can be built in areas without any resources. When the present invention is used, the water in the pool is injected once and used permanently. There is no need to frequently draw water from nearby. It can be built in places without any resources, reducing construction costs.

[0056] During the specific implementation of the present invention, the installation of the multifunctional power machine is as follows: when building the water pool, an interface with a flange is pre-buried at the bottom, a ball valve is connected to the interface, and a multi-blade spiral directional water wheel cover is provided with 8 holes with a length of 5 cm, and the upper end is connected to the ball valve; the water outlet at the lower end of the multifunctional power machine protrudes 30 cm and cooperates with the hole reserved at the bottom of the generator room, and is directly inserted into the reserved hole for full sealing during installation; the multifunctional power machine is directly placed on the floor, and the multifunctional power machine is fixed with a criss-cross frame at the top, middle and bottom.

[0057] There are several groups of generator sets installed in the generator room, with 10 generator sets in a group. Each multifunctional power machine is directly connected to the bottom of the pool through a ball valve and the interface pre-buried when the pool was built. The multi-leaf spiral directional water wheel cover plate has 8 prefabricated 5-centimeter-long interfaces to connect the ball valve directly to the pool. The bottom cover plate of the multifunctional power machine is prefabricated with a water outlet hole with a length of 30 centimeters, which directly leads to the circulating water channel.

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

[0059] There are criss-crossing circulating water channels at the bottom of the machine room leading to both sides of the generator room. Multiple sets of multi-blade multi-functional energy-saving water pumps return water to the pool for repeated circulation to generate electricity.

[0060] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
