Description

Technical Field

[0001] The invention relates to the technical field of hydroelectric power generation, in particular to a coupling device for generating power from water and co-producing cool wind in static waters. Background Art

[0002] With the implementation of the "dual carbon" policy, countries around the world are vigorously developing various clean energy sources such as wind, solar, and hydropower.

[0003] There are many different ways of hydroelectric power generation, but basically they all utilize suitable terrain, topography or building dams to use the kinetic energy or potential energy generated by flowing dynamic water to generate hydroelectric power. However, static water such as the sea, lakes, and reservoirs are called static waters. It is somewhat difficult to use the kinetic energy or potential energy of water to leave the original water area to generate electricity.

[0004] In recent years, due to the continuous increase in the total amount of carbon emissions, the earth's surface has been warming. Every summer, people need a lot of natural cool air to cool down. Many people cannot adapt to artificial refrigeration (cooling) and suffer from air conditioning disease. At the same time, there are practical problems such as unenvironmental and unhygienic indoor air, which cause difficulties in summer life. With the improvement of people's health and living standards, people are eager for natural refrigeration and artificial natural cold sources; the development of pure natural refrigeration (cooling) methods such as deep well water or natural ice cooling is affected and restricted by factors and conditions such as environment, conditions, materials, and cost. It is difficult to obtain a large amount of low-cost pure natural cold air or cool wind to cool down. However, due to the limitations of the environment and conditions, most people can only use air conditioners for cooling down.

[0005] At present, there are two ways of refrigeration (cooling) at home and abroad:

[0006] Natural refrigeration (cooling): Deep well water or natural ice cools objects, generally achieving a temperature of 8°C to 27°C.

[0007] Artificial cold sources: There are liquid vaporization method, gas expansion method, thermoelectric method, solid adiabatic demagnetization method, etc. Different refrigeration (cooling) methods are suitable for obtaining different temperatures.

[0008] There are many types of artificial refrigeration methods in different forms. The energy used for refrigeration is also different. Some use electricity as energy, such as compression refrigerators that use ammonia, fluorine and other working fluids to achieve refrigeration cycles; some use steam as energy, such as steam-type lithium bromide absorption refrigerators; and some use other thermal energy as energy, such as hot water lithium bromide refrigerators, lithium bromide refrigerators that directly burn oil or natural gas, and solar absorption refrigerators. It is to consume a certain amount of energy in exchange for transferring the heat of a low-temperature object to a high-temperature object, thereby obtaining a low temperature. Liquid vaporization heat absorption refrigeration is a refrigeration method commonly used at home and abroad. Summary of the invention

[0009] The technical problem to be solved by the present invention is to provide a coupling device for off-water power generation and co-generation of cool wind in static waters, a semi-submersible hull structure is built on the water surface of a relatively static water body with a certain depth such as a sea, lake, reservoir, pond, etc., or a deep-water tank assembly of appropriate size sunk under the water body is excavated next to the water body, and a siphon pipe artificially set underwater forms a water flow potential energy of more than 10m, which is used as a power water source for a water turbine pump and as a water source for pumping water for a high-pressure water pump, and then the deep water is lifted to a height of 10 to 50m above the water surface for residual pressure water power generation, and its tail water flows into a high-level water storage tank again, and then an equal amount of water is released from the high-level water storage tank, and the height difference potential energy formed by the height from the deck or the ground is used for secondary power generation, and the residual water of the deep-water tank is lifted to a high-level water tank by an air lift ejector and natural cool wind is separated, and the water is then gathered in the water storage tank or discharged in other forms, and this cycle is repeated to enable a coupling device for off-water power generation and co-generation of cool wind in static waters.

[0017] As a further limitation of the technical solution, the deck is connected to the anchor hooks through a group of steel cables and is hung firmly on the bottom of the water.

[0018] As a further limitation of the technical solution, the bottom layers of the deep-water tank assembly and the hull structure are respectively filled with a certain amount of counterweights.

[0019] Compared with the prior art, the advantages and positive effects of the present invention are:

[0020] The deepwater tank of the present invention is 10 to 50 meters below the water surface, and a siphon drop is artificially created to provide potential energy for the water turbine pump. It is difficult for static waters such as the sea, lakes, reservoirs, ponds, etc. to form waterfalls and large drop hydraulic potential energy for hydroelectric power generation like rivers. For this reason, the present invention artificially forms a large drop on the calm water surface to meet the deepwater tank water turbine pump in the deepwater tank assembly to form sufficient potential energy power. The deck under the hull structure is tightly connected to the deepwater tank assembly. The elevation of the deepwater tank platform is about 10 to 50 meters below the water surface, and the minimum drop is also 7 to 8 meters. If we want to ensure that the liquid level of the deep-water tank never exceeds the elevation of the deep-water tank platform, then there will always be a 7-20m drop between the deep-water tank platform and the water surface, and the water body will form a siphon phenomenon through the water inlet of the water supply pipe and the underwater siphon water supply pipe and the inlet of the deep-water tank water turbine pump, and it will be circulated back and forth, and provide a water flow with a pressure of 0.07-0.2MPa for the deep-water tank water turbine pump. The deep-water tank water turbine pump tail water formed by the deep-water tank water turbine pump is automatically discharged and flows into the bottom of the deep-water tank assembly to become the deep-water tank water body. The deep-water tank water turbine pump uses its potential energy to convert into a powerful mechanical power, instead of using electrical energy to provide the high-pressure water pump with kinetic energy for pumping water, thereby pumping out the water in the deep-water tank water body. However, the high-pressure water pump can only extract 50-60% of the water in the deep-water tank water body, and there is still 40-50% of the remaining water, which remains at the bottom of the deep-water tank assembly, forming the deep-water tank water body The remaining water needs to be discharged in time.

[0021] The deep water tank of the present invention uses a high-pressure water pump to pump out most of the water, and the remaining water is then pumped out by a venturi ejector. The water body forms a siphon phenomenon between the water inlet of the water supply pipe and the underwater siphon water supply pipe and the inlet of the deep water tank water turbine pump. After the deep water tank water turbine pump converts powerful mechanical kinetic energy, the tail water of the deep water tank water turbine pump all enters the deep water tank water body of the deep water tank assembly, and 50-60% of the water volume is pumped out by the high-pressure water pump driven by the deep water tank water turbine pump. The remaining 40-50% of the remaining water is still retained at the bottom of the deep water tank assembly, that is, the deep water tank water body, which needs to be discharged in time, otherwise, the deep water tank assembly will be filled in a short time, and the liquid level of the deep water tank will be level with the water surface, and the present invention will not have any innovation. Therefore, the present invention also has a set of Venturi air lift ejector devices at the bottom of the deep water tank assembly, which will rely on automatic control equipment to lift the remaining deep water tank water at the bottom of the deep water tank assembly into the high-level water tank through the outlet of the Venturi air lift ejector, and spray water above the liquid level of the high-level water tank. Natural cool wind can be separated from the high-level water tank at the same time. The water then passes through the water outlet of the high-level water tank to provide hydraulic kinetic energy for power generation for the high-level generator set in the high-level water tank, and performs a residual pressure power generation. The Venturi air lift ejector relies on the signal of the high-level water tank liquid level gauge to automatically control the device to open or close, and perform intermittent work to ensure that the liquid level of the deep water tank is always below 1 to 2 meters below the deep water tank platform.

[0022] The power of the air compressor of the present invention comes from external electric energy such as wind power, photovoltaic power generation and energy storage. The power source of the Venturi air lift ejector is compressed air, and the air compressor provides compressed air to the air pressure tank. The pressure of the compressed air released by the air pressure tank is determined according to the height of the high-level water tank, generally 0.3-0.8MPa, and its pressure can be higher in special cases. The work of the air compressor is intermittent, and its electric energy comes from other external electric energy such as breeze wind turbines, photovoltaic panels and energy storage.

[0023] The residual water in the deep water tank of the present invention can be discharged in various forms. The drainage method of the deep water tank water body in the deep water tank assembly is the key core technology of the present invention. There are several drainage methods. The present invention innovatively provides two methods: 1. The air compressor driven by electric power + Venturi air lift ejector system provides a gas-liquid energy drainage method of compressed air. See Figure 1 to Figure 5 ; 2 Direct pumping and drainage of large-flow submersible pumps driven by electric power, see Figure 6 to Figure 8 .

[0024] The present invention realizes three hydroelectric power generation. The first hydrokinetic energy generation: the deep-water tank water turbine pump utilizes the potential energy formed by its siphon pipe to transform the powerful mechanical power to provide the high-pressure water pump with the power to pump water. The head of the high-pressure water pump can reach 30-300m. According to the head height, the high-pressure water pump can extract 50-60% of the water volume of the underwater water supply pipe, and spray it through the high-pressure water pump water pipe and the high-pressure water pump water pipe outlet. The head pressure is generally 0.3-3.0MPa, which is used for the high-level generator set in the high-level water tank to generate the first residual pressure power; the second hydroelectric potential energy generation: after the deep-water tank water turbine pump generates the first power, all the water in the high-level water tank flows into the high-level water storage tank, and the water storage tank downpipe discharges the same amount of water and enters the deck generator set. The height difference between the two is generally 10-50m, which provides the deck generator set on the deck with hydraulic potential energy to generate electricity. After the tail water of the deck water turbine pump is discharged from the deck water turbine pump drain port, it returns to the water body under the water surface, and the second hydroelectric power generation is performed. The third hydrokinetic energy power generation: After the tail water of the deck turbine pump is discharged from the drain port of the deck turbine pump, before it returns to the water body under the water surface, due to its large amount of water, the flow rate of the drain port of multiple sets of deck turbine pumps is tens of thousands to millions of cubic meters per hour. A flow trough with a ramp can be installed to collect all the tail water of the deck turbine pump. According to the length of the chute, one or more sets of turbine generator systems can be installed to generate electricity in the form of a chute turbine, and the final tail water flows into the water body again.

[0025] High-level water storage tanks can be large or small, designed and manufactured according to your own requirements. High-level water storage tanks can be built above the hull structure, on the high slope of land, or on the top of a building. Large high-level water storage tanks can also be used for aquaculture, and can also be used for irrigation of farmland and other applications.

[0026] The invention generates electricity and produces natural cool wind. The compressed air released from the air pressure tank is injected into the annular high-pressure wind chamber through the compressed air air supply pipe, and is sprayed to the throat of the Venturi air lift ejector through multiple rows of evenly arranged upward inclined air nozzles and upward curved air nozzles, driving the water inlet of the Venturi air lift ejector to rise. At the same time, the compressed air and water are fully mixed and heat exchanged, and the temperature of the compressed air is consistent with the water temperature. Since the water inlet of the water supply pipe is 10 to 50 meters below the water surface, the water temperature is relatively low. Therefore, the temperature of the compressed air and water after thorough heat exchange is consistent, and the compressed air is lifted from the Venturi air lift ejector through the Venturi air lift ejector outlet to the high-level water tank in the high-level water tank and sprayed out. At the same time, natural cool wind is automatically separated in the high-level water tank, and the cool wind is discharged through the cool wind outlet to replace the cold wind of the air conditioner to cool the room, so that people can enjoy the refreshing cool wind of nature. It should be noted that due to the different water temperatures in winter and summer, the water temperature in the deep water in summer is generally 8-27℃, and the water temperature in the deep water in winter is 12-23℃. Therefore, the wind separated from the high-level water tank is a cool wind of 8-27℃ in summer, and a warm wind of 12-23℃ in winter. When the high-level water tank is determined to be 20-50m, the Venturi air lift ejector 15 is lifted every 2-3m. 3 (t) of water, approximately 1Nm 3 In other words, 1Nm 3 Compressed air can lift 2 to 3 meters 3 (t) of water.

[0027] The invention has a wide range of applications. It can be widely used in static waters such as seas, lakes, reservoirs, ponds, etc. to carry out water separation and hydroelectric power generation to produce natural cool breeze, and is also suitable for dynamic water in rivers to carry out water separation and hydroelectric power generation to produce natural refreshing cool breeze.

[0037] A specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific implementation.

[0038] The present invention builds a deep-diving, semi-submersible hull or silo structure device above or beside the static water area, uses an artificial siphon to artificially turn the static water into dynamic water, and uses the dynamic water flow potential energy as the power water source of the water turbine pump and as the water source for the high-pressure water pump to pump water, and lifts the water to a high-level water reservoir above the water surface at high pressure, firstly performs water pipe residual pressure power generation, and the tail water then flows into the high-level water reservoir. At the same time, the high-level water reservoir releases an equal amount of water, and uses the potential energy of the drop between it and the deck or the ground to perform secondary power generation, and uses the residual water in the silo to lift it to the high-level water reservoir by an air lift ejector and separate the cool air or use other drainage methods, and repeats this cycle, so that the static water area can be separated from the water to generate power and produce cool air in a coupled body device.

[0039] Embodiment 1: The present invention comprises: a hull structure 44, which is divided into two major parts, above water and underwater, and a deck 1 part, totaling three parts; a high-level platform 9 is installed above 10 to 50 meters of the deck 1, a water tank bracket 29 is installed on the high-level platform 9, a high-level water tank 27, a breeze wind generator 25 and a photovoltaic power generation panel 28 are installed on the water tank bracket 29, and a high-level water tank 19, a high-level water tank 26 and a high-level generator set 24 are also provided above the high-level water tank 27, and the high-level water tank 27, the breeze wind generator 25 and the photovoltaic power generation panel 28 are respectively installed on the high-level platform 9; a deck generator set 31 is installed on the deck 1; the deck 1 is tightly connected to the deep-water tank assembly 38, and the deep-water tank platform 4 is fixedly connected to the deep-water tank assembly 38 penetrating the bottom of the hull structure 44. The deep water bin assembly 38 is separated into two layers, an upper layer and an lower layer, by the deep water bin platform 4, and the lower layer is a deep water bin water body 43. A deep water bin water turbine pump 12 and a high-pressure water pump 13 are installed on the upper side of the deep water bin platform 4, and the two are connected by a V-belt, a coupling and other methods. The deep water bin assembly 38 is connected to a U-shaped underwater siphon water supply pipe 5, and the underwater siphon water supply pipe 5 is provided with a water supply pipe inlet 6. The water supply pipe inlet 6 penetrates deep into the water body 3 in order to take out cool water from the deep water body so as to obtain cool breeze in the later stage; therefore, the water supply pipe inlet 6 only needs to be buried in any part of the water body 3 below the water surface 2; the underwater siphon water supply pipe 5 is fixedly connected to the deep water bin water turbine pump 12, the high-pressure water pump 13 is fixedly connected to the high-pressure water pump inlet pipe 14, the high-pressure water pump 13 is fixedly connected to the high-pressure water pump lifting pipe 16, and the high-pressure water pump lifting pipe 16 is connected to the high-position platform 9.

[0040] In the fresh water body 3, the deck 1 of the hull structure 44 and the steel structure materials and facilities above and below the water surface 2 can be welded and manufactured using ordinary carbon steel, ship plate and weathering steel, and sprayed with paint after completion;

[0041] If the device is used in a body of water 3 in seawater, the deck 1 of the hull structure 44 and the steel structure materials and facilities above the water surface 2 can be welded and manufactured using weathering steel and corrosion-resistant stainless steel; below the water surface 2, the parts of the deep-water tank assembly 38 in contact with seawater are all welded and manufactured using stainless steel materials resistant to seawater corrosion, and are sprayed with special paint to prevent the attachment of barnacles and seaweed.

[0042] The upper opening of the deepwater bunker assembly 38 is below the deck 1, so that the water body 3 of the water surface 2 or rainwater will not easily flow into its interior. Its own welding must also be firm and no water seepage can occur. The deepest part of the hull structure 44 is the bottom of the deepwater bunker assembly 38, which is generally required to be above the bottom bed 7. The depth of the deepwater bunker assembly 38 can be designed according to the total depth of the water body 3 to avoid the hull structure 44 from running aground. The shape of the deepwater bunker assembly 38 can be a square box or a cylinder, which can be determined according to local conditions and on-site conditions; its material can be welded with stainless steel and weathering steel, or made of carbon fiber, basalt fiber, glass fiber reinforced plastic fiber, or a concrete structure and a brick masonry structure, as long as it meets the engineering requirements of strength and anti-leakage. The deepwater bunker assembly 38 penetrates the bottom of the hull structure 44 and is connected to the deck 1. In the water body 3, it also plays a role in stabilizing the hull structure 44.

[0043] The elevation of the deep-water storage platform 4 is about 10-20 m lower than the water surface 2, and the minimum height difference is also 7-8 m.

[0044] The deep-water tank water turbine pump 12 can also be a water turbine pump, a water hammer pump or other power turbine pumps. The power of the deep-water tank water turbine pump 12 comes from the underwater siphon water supply pipe 510-20m drop, forming vertical hydraulic potential energy. The deep-water tank water turbine pump tail water 45 generated by the deep-water tank water turbine pump 12 after working automatically flows into the deep-water tank water body 43 at the bottom of the deep-water tank assembly 38.

[0045] The underwater siphon water supply pipe 5 is in the shape of a siphon tube, and the water inlet 6 of the water supply pipe is arranged below 10m below the water body 3 of the water surface 2, in order to avoid solid garbage in the water body 3 of the water surface 2 and to prevent air from being sucked in, and at the same time, to extract cool water from under the water body 3.

[0046] The high-pressure water pump 13 is determined according to the height of the high-position generator set 24. Generally, the head of the high-pressure water pump 13 is 100-400m. The head of the high-pressure water pump 13 can be selected to be 60-150m. Since the height of the high-position generator set 24 of the present invention is generally 20-50m, it can fully meet the head power required for its power generation. The water pumping volume of the high-pressure water pump 13 is inversely proportional to the head, and its water pumping volume is generally 40-50% of the water intake of the deep-water tank water turbine pump 12. The high-pressure water pump 13 is used to extract the remaining water in the deep-water tank water body 43. The high-pressure water pump water inlet pipe 34 of the high-pressure water pump water inlet pipe 14 is arranged in the middle and lower part of the deep-water tank water body 43.

[0047] There will be 40-50% of residual water in the deep water tank water body 43 which is not pumped out by the high pressure water pump 13. After a period of time, the deep water tank liquid level 33 of the deep water tank water body 43 will soon pass the deep water tank platform 4 until it is level with the water surface 2.

[0048] The high-pressure water pump water pipe outlet 17 of the high-pressure water pump water pipe 16 and the high-position water tank outlet 23 of the high-position water tank 19 are directly opposite to the high-position generator set 24 .

[0049] The high-position water storage tank 27 can be large or small, and can be designed and manufactured according to one's own requirements. The high-position water storage tank 27 can be built above the hull structure 44, or can be built on a high slope on land. A large high-position water storage tank 27 can also be used for breeding, or can be used for applications such as irrigation of farmland.

[0050] The deck generator set 31 can be a turbine generator set, a water wheel pump generator set, a water wheel generator set, or any other form of hydraulic generator set.

[0051] The high-position water tank 19 is provided with a cool air outlet 21 .

[0052] The high-level water reservoir 27 is fixedly connected to the water reservoir downpipe 30 , and the water reservoir downpipe 30 is fixedly connected to the deck generator set 31 . The deck generator set 31 is provided with a deck turbine pump drain port 32 for discharging tail water 46 of the deck turbine pump.

[0053] The deck 1 is connected to the anchor hook 8 through a set of steel cables and is hung firmly on the bottom bed 7, so that the hull structure 44 is firmly fixed in the semi-submerged water body 3 without drifting; the hull structure 44 can be semi-submerged or fixed.

[0054] The bottom layers of the deep-water storage assembly 38 and the hull structure 44 are respectively filled with a certain amount of counterweight blocks 35 to ensure the overall stability of the deep-water storage assembly 38 and the hull structure 44 .

[0055] The deep-water tank water turbine pump 12 can be a water turbine pump or a water hammer pump.

[0056] Embodiment 2: This embodiment is further described on the basis of embodiment 1. A Venturi air lift ejector 15 is installed in the deep water tank assembly 38. The Venturi air lift ejector 15 includes a high-pressure air chamber 39 and a water inlet 36 of the Venturi air lift ejector. The high-pressure air chamber 39 is fixedly connected to the water inlet 36 of the Venturi air lift ejector. The high-pressure air chamber 39 is fixedly connected to the compressed air supply pipe 18. The high-pressure air chamber 39 is provided with a group of upward inclined air nozzles 41 and a group of upward curved air nozzles 42. The high-pressure air chamber 39 is fixedly connected to the throat 40 of the venturi air lift ejector, and the throat 40 of the venturi air lift ejector is fixedly connected to the steel pipe pipeline, and the steel pipe pipeline is fixedly connected to the high-level water tank 19. The steel pipe pipeline is provided with a venturi air lift ejector outlet 22. An air compressor 10 and an air pressure tank 11 are installed on the deck 1. The air compressor 10 and the air pressure tank 11 are connected through a pipeline, and the compressed air supply pipe 18 is fixedly connected to the air pressure tank 11. In order to ensure that the deep water tank liquid level 33 of the deep water tank water body 43 in the deep water tank assembly 38 is always lower than the deep water tank platform 4, a set of venturi air lift ejectors 15 is provided in the deep water tank water body 43.

[0057] The compressed air is filled into the high-pressure air chamber 39 through the air supply duct 18. The high-pressure air chamber 39 is annular and consists of several rows of evenly arranged upward inclined air nozzles 41 and upward curved air nozzles 42 with a diameter of 3 to 10 mm. The sum of the cross-sectional areas of the several rows of evenly arranged upward inclined air nozzles 41 and upward curved air nozzles 42 in the high-pressure air chamber 39 should be equal to and slightly larger than the cross-sectional area of ​​the compressed air supply duct 18. The wind speed of the compressed air supply duct 18 can be controlled at 2.5 to 3.0 m / s, and the specific situation can be adapted to local conditions.

[0058] The upward inclined air nozzles 41 are formed on the pipe wall with an inclination of 40 to 60 degrees.

[0059] The high-pressure wind blows toward the throat 40 of the Venturi air lift ejector, and at the same time drives the water inlet 36 of the Venturi air lift ejector to enter the throat 40 of the Venturi air lift ejector. After the compressed gas is evenly mixed with the water, it passes through the Venturi air lift ejector 15 and the outlet 22 of the Venturi air lift ejector and is injected into the high-level water tank 19. The outlet 22 of the Venturi air lift ejector is higher than the liquid level 20 of the high-level water tank. The temperature of the compressed air is consistent with the water temperature. At this moment, the water temperature is generally between 8°C and 25°C. At the same time, the compressed air is separated from the water in the high-level water tank 19, and the compressed air forms a cool breeze with a temperature of 8°C to 25°C, and then passes through the cool breeze outlet 21 to be used indoors to replace the air conditioning wind and cool the indoors. The venturi air lift ejector 15 works intermittently, and its automatic control system is interlocked with the water level gauge of the deep water tank liquid level 33. When the deep water tank liquid level 33 rises to a specified position, the electromagnetic valve of the air pressure tank 11 outlet is automatically started, and the venturi air lift ejector 15 starts to lift water; otherwise, when the deep water tank liquid level 33 drops to a specified position, the electromagnetic valve of the air pressure tank 11 outlet is automatically closed, and the venturi air lift ejector 15 stops lifting water; the cycle works over and over again.

[0060] It is best to have a spare set of Venturi air lift ejector 15, so that one is in use and one is in reserve, to ensure that the height of the deep water tank liquid level 33 cannot exceed the deep water tank platform 4, and also to ensure that the entire deep water tank assembly 38 works smoothly as a whole, so that the equipment does not have any faults.

[0061] The power of the Venturi air lift ejector 15 is compressed air, which is provided by the air compressor 10 to the air pressure tank 11. The pressure of the compressed air released by the air pressure tank 11 is determined according to the height of the high-level water tank 19, which is generally 0.3-0.8 MPa. In special cases, the pressure can be higher.

[0062] The air compressor 10 works intermittently, and its electric energy comes from the micro wind turbine 25, the photovoltaic panel 28 and energy storage.

[0063] Embodiment 3: This embodiment is further elaborated on the basis of embodiment 1. A steel structure bracket 55 is installed on the upper inner wall of the deep water tank assembly 38. A deep water tank hanging water tank 47 is arranged in the steel structure bracket 55. The deep water tank assembly 38 is equipped with at least one set of large flow submersible pumps 48 corresponding to the deep water tank water body 43. The large flow submersible pumps 48 are fixedly connected to the submersible pump water supply pipe 49. The submersible pump water supply pipe 49 is fixedly connected to the deep water tank assembly 38. The submersible pump water outlet 50 of the submersible pump water supply pipe 49 faces the deep water tank hanging water tank 47. The tail water of the deep water tank turbine pump 12 is discharged at the submersible pump water outlet 50 through the large flow submersible pump 48 and the submersible pump water supply pipe 49, and flows into the deep water tank hanging water tank 47.

[0064] A deep water tank turbine pump 51 and a high pressure water pump 52 are installed on the upper side of the deep water tank platform 4, and the two are connected by a V-belt, a coupling and other methods. The deep water tank turbine pump 51 is fixedly connected to an internal water tank downpipe 56, and the internal water tank downpipe 56 is fixedly connected to the deep water tank internal water tank 47. The high pressure water pump 52 is fixedly connected to a high pressure water pump second water pipe 53, and the high pressure water pump second water pipe 53 is fixedly connected to the high-level platform 9, and the high pressure water pump second water pipe outlet 54 of the high pressure water pump second water pipe 53 is facing the high-level generator set 24.

[0065] The distance between the lower side of the deep-water tank 47 and the deep-water tank platform 4 is about 10m. The water 57 in the deep-water tank flows into the deep-water tank water turbine pump 2 51 and the high-pressure water pump 2 52 installed on the deep-water tank platform 4 through the downpipe 56 of the deep-water tank. The water is transported through the high-pressure water pump 2 pumping pipe 53 and the high-pressure water pump 2 pumping pipe outlet 54, and the water flow of the high-pressure water pump pumping pipe outlet 17 is combined, and then transported to the high-position generator set 24 for residual pressure power generation. Another way of draining the deep-water tank water body 43 is realized.

[0066] Embodiment 4: There are also various methods such as water hammer pump water pumping and drainage method, high-pressure water pump liquid flow energy drainage method, that is, using high-pressure water instead of compressed air to provide water-lifting power for the Venturi air lift ejector 15, micro-bubble power energy drainage method, etc., all of which can realize micro-energy-consuming power-driven pumping method, and realize timely drainage of excess water in the deep water tank water body 43.

[0067] The deepwater tank of the present invention is 10 to 50 meters below the water surface, and a siphon drop is artificially created to provide potential energy for the water turbine pump. It is difficult for static waters such as the sea, lakes, reservoirs, ponds, etc. to form waterfalls and large drop hydraulic potential energy for hydroelectric power generation like rivers. For this reason, the present invention artificially forms a large drop on the calm water surface to meet the deepwater tank water turbine pump 12 in the deepwater tank assembly 38 to form sufficient potential energy power. The deck 1 of the hull structure 44 is tightly connected to the deepwater tank assembly 38. The elevation of the deepwater tank platform 4 is about 10 to 50 meters lower than the water surface 2, and the minimum drop is also 7 to 8 meters. If it is to be ensured that the deep water tank liquid level 33 never exceeds the elevation of the deep water tank platform 4, then there will always be a 7-20m drop between the deep water tank platform 4 and the water surface 2, and the water body 3 will form a siphon phenomenon through the water supply pipe inlet 6 and the underwater siphon water supply pipe 5 and the inlet of the deep water tank water turbine pump 12, and the circulation will be repeated, and a water flow with a pressure of 0.07-0.2MPa will be provided to the deep water tank water turbine pump 12. The deep water tank water turbine pump tail water 45 formed by the deep water tank water turbine pump 12 will be automatically discharged and flow into the bottom of the deep water tank assembly 38 to become the deep water tank water body 43. The deep water tank water turbine pump 12 uses its potential energy to convert into a powerful mechanical power, instead of using electrical energy to provide the high pressure water pump 13 with kinetic energy for pumping water, thereby pumping out the water in the deep water tank water body 43. However, the high-pressure water pump 13 can only extract 50-60% of the water in the deep water tank water body 43, and 40-50% of the remaining water remains at the bottom of the deep water tank assembly 38, forming the deep water tank water body 43 The remaining water needs to be discharged in time.

[0068] The deep water tank of the present invention uses a high-pressure water pump to pump out most of the water, and the remaining water is then pumped out by a venturi ejector. The water body 3 forms a siphon phenomenon between the water supply pipe inlet 6 and the underwater siphon water supply pipe 5 and the inlet of the deep water tank water turbine pump 12. After the deep water tank water turbine pump 12 converts powerful mechanical kinetic energy, the tail water 45 of the deep water tank water turbine pump all enters the deep water tank water body 43 of the deep water tank assembly 38, and 50-60% of the water volume is pumped out by the high-pressure water pump 13 driven by the deep water tank water turbine pump 12. The remaining 40-50% of the remaining water is still retained at the bottom of the deep water tank assembly 38, that is, the deep water tank water body 43, which needs to be discharged in time, otherwise, the deep water tank assembly 38 will be filled in a short time, and the deep water tank liquid level 33 will be level with the water surface 2, and the present invention will not have any innovation. Therefore, the present invention also has a set of Venturi air lift ejector 15 devices at the bottom of the deep water tank assembly 38, which can rely on automatic control equipment to lift the remaining deep water tank water 43 at the bottom of the deep water tank assembly 38 into the high-level water tank 19 through the Venturi air lift ejector outlet 22, and eject water above the high-level water tank liquid level 20. The high-level water tank 19 can simultaneously separate natural cool air, and the water then passes through the high-level water tank outlet 23 to provide hydraulic kinetic energy for power generation for the high-level generator set 24 in the high-level water tank 26, thus performing a residual pressure power generation. The Venturi air lift ejector 15 is automatically controlled by the liquid level gauge signal of the high-level water tank liquid level 20 to open or close the device, and perform intermittent work to ensure that the deep water tank liquid level 33 is always 1 to 2 meters below the deep water tank platform 4.

[0069] The power of the air compressor of the present invention comes from external electric energy such as wind power, photovoltaic power and energy storage. The power source of the Venturi air lift ejector 15 is compressed air, and the air compressor 10 provides compressed air to the air pressure tank 11. The pressure of the compressed air released by the air pressure tank 11 is determined according to the height of the high-level water tank 19, generally 0.3-0.8MPa, and its pressure can be higher in special cases. The work of the air compressor 10 is intermittent, and its electric energy comes from other external electric energy such as breeze wind turbines 25, photovoltaic panels 28 and energy storage.

[0070] The residual water in the deep water tank water body of the present invention can be discharged in various forms. The drainage method of the deep water tank water body 43 in the deep water tank assembly 38 is the key core technology of the present invention, and there are several drainage methods. The present invention innovatively provides two methods: 1. The air compressor 10 + Venturi air lift ejector 15 system driven by electric power, the gas-liquid energy drainage method provided by the compressed air is detailed in Figure 1 to Figure 5 ; 2 Electric power driven large flow submersible pump 48 Direct pumping and drainage method see Figure 6 to Figure 8 .

[0071] The present invention realizes three-time hydroelectric power generation. The first hydrokinetic energy generation: the deep-water tank water turbine pump 12 utilizes the potential energy formed by its siphon pipe to transform the powerful mechanical power to provide the high-pressure water pump 13 with the power to pump water. The head of the high-pressure water pump 13 can reach 30 to 300 meters. According to the head height, the high-pressure water pump 13 can extract 50 to 60% of the water volume of the underwater siphon water supply pipe 5 and spray it through the high-pressure water pump water pipe 16 and the high-pressure water pump water pipe outlet 17. The water head pressure is generally 0.3 to 3.0 MPa, which is used for the high-level generator set 24 in the high-level water tank 26 to carry out residual The first power generation is performed by the water turbine pump 12 in the deep water tank; the second power generation is performed by the hydraulic potential energy: after the first power generation by the water turbine pump 12 in the deep water tank, all the water in the high-level water tank 26 flows into the high-level water storage tank 27, forming the liquid level 37 of the high-level water storage tank. The downpipe 30 of the water storage tank discharges water in equal amounts and enters the deck generator set 31. The height difference between the two is generally 10 to 50 meters, providing hydraulic potential energy for the deck generator set 31 on the deck 1 to generate electricity. After the tail water 46 of the deck water turbine pump is discharged from the drain port 32 of the deck water turbine pump, it returns to the water body 3 under the water surface 2, and the second hydroelectric power generation is performed. The high-level water storage tank 27 can be large or small, and can be designed and manufactured according to its own requirements. The high-level water storage tank 27 can be built above the hull structure 44, or on a high slope on land, or on the top of a building. A large high-level water storage tank 27 can also be used for breeding, and can also be used for irrigation of farmland and other applications. The third hydrokinetic energy generation: after the tail water 46 of the deck turbine pump is discharged from the drain port 32 of the deck turbine pump, before returning to the water body 3 under the water surface 2, due to its large amount of water, the flow rate of the drain ports of multiple sets of deck turbine pumps is in the range of tens of thousands to millions of cubic meters per hour. A flow trough with a ramp can be installed to collect all the tail water of the deck turbine pump. According to the length of the chute, one or more turbine generator systems can be installed to generate electricity in the form of a chute turbine, and the tail water finally flows into the water body 3.

[0072] The invention generates electricity and co-generates natural cool breeze. The compressed air released by the air pressure tank 11 is injected into the annular high-pressure air chamber 39 through the compressed air supply pipe 18, and is sprayed to the throat 40 of the Venturi air lift ejector through multiple rows of evenly arranged upward inclined air nozzles 41 and upward curved air nozzles 42, driving the water inlet 36 of the Venturi air lift ejector to rise. At the same time, the compressed air and water are fully mixed and heat exchanged, and the temperature of the compressed air is consistent with the water temperature. Since the water inlet 6 of the water supply pipe is 10 to 50 meters below the water surface 2, its water temperature is relatively low. Therefore, the temperature of the compressed air and water after thorough heat exchange is consistent, and the compressed air is lifted from the Venturi air lift ejector 15 through the Venturi air lift ejector outlet 22 to the high-level water tank 19 above the liquid level 20 of the high-level water tank and sprayed out. At the same time, natural cool air will be automatically separated in the high-level water tank 19, and the cool air will be discharged through the cool air outlet 21 to replace the cold air of the air conditioner to cool the room and let people enjoy the refreshing cool air of nature. It should be noted that: due to the different temperatures of the water body 3 in winter and summer, the water temperature in the deep water in summer is generally 8-27°C, and the water temperature in the deep water in winter is 12-23°C. Therefore, the wind separated by the high-level water tank 19 is a cool wind of 8-27°C in summer, and a warm wind of 12-23°C in winter. When the high-level water tank 19 is determined to be 20-50m, the Venturi air lift ejector 15 is lifted every 2-3m. 3 (t) of water, approximately 1Nm 3 In other words, 1Nm 3 Compressed air can lift 2 to 3 meters 3 (t) of water.

[0073] The invention has a wide range of applications. It can be widely used in static waters such as seas, lakes, reservoirs, ponds, etc. to carry out water separation and hydroelectric power generation to produce natural cool breeze, and is also suitable for dynamic water in rivers to carry out water separation and hydroelectric power generation to produce natural refreshing cool breeze.

[0074] The above disclosure is only a specific embodiment of the present invention, but the present invention is not limited thereto, and any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
