Description

Technical Field

[0001] The present invention relates to the technical field of offshore data centers, and in particular to an offshore data platform and an energy storage system of the offshore data platform. Background Art

[0002] In my country, many data centers are built in places where wind power and photovoltaic power generation are relatively cheap in order to save costs, but the disadvantage is that these places are far away from developed coastal cities. For technology fields that require high data computing and transmission speeds, such as high-frequency financial trading, autonomous driving, artificial AI training models, and telemedicine, the shorter the distance to the data center, the better. The ocean closest to coastal cities has abundant energy, such as wind power, wave power, tidal power, solar power, and temperature difference power generation, etc. There is also a water depth of 10 meters, which is about one atmosphere. If deep sea water pressure can be used for energy storage, it can also provide a good guarantee for the power consumption of the data center; the heat transfer derivative of water is about 23 times that of air, and the heat dissipation of the data center accounts for a large proportion of the electricity consumption. If the data center is built on the sea, it can provide sufficient power supply for data computing, deep sea energy storage guarantee, and take into account heat dissipation, killing two birds with one stone.

[0003] In the application of submarine data cabins, the data cabins of technology companies such as Microsoft are completely sealed and sunk to the bottom of the sea. Complete sealing has a big disadvantage. If the graphics card, CPU and other parts in the data cabin fail, the entire data cabin must be lifted up and replaced on shore for repair, which is very troublesome.

After the upper connecting port is connected, the air in the two compartments can flow freely; after the lower connecting port is connected, the seawater in the two compartments can flow freely.

[0025] The generator power output is connected to the adjustable load device through the controller; when the wind speed is lower than the normal cut-in wind speed, the controller switches to the adjustable load device, lowering the generator output load to reduce the generator input torque, so that the low-pressure air generated by the fan air compressor can blow the turbine to generate electricity;

[0026] The equipment cabin includes a turbine, which is connected to the generator through a clutch, and the turbine is connected to the generator through a clutch; there are reinforcement plates in the storage cabin to strengthen the cabin structure, and the reinforcement plates are dug with upper, middle and lower holes to facilitate the circulation of water and air in the cabin;

[0035] Step three: Close the third water valve and open the second water valve and the second air valve at the same time. At this time, the water coming out of the turbine enters a cabin through the second water valve, and the air in cabin one is exhausted to the exhaust port through the second air valve; because the deep sea water is uninterrupted, it continues to enter the turbine from the water inlet, and the turbine continues to rotate to generate electricity; when the water level and pressure sensor senses that the water level in cabin one is about to reach the maximum water level, close the second air valve, and seawater continues to enter cabin one to squeeze the air in the cabin; when the water level and pressure sensor senses that the air pressure in cabin one reaches the working value of the air compression energy storage pressure input, close the second water valve to end the water intake of cabin one, the turbine stops taking in water, close the first water valve, the water intake and power generation of cabin one ends, and the turbine separates the generator through the clutch.

The floating platform 1 is connected to the underwater heat dissipation cabin by a channel 5; the anchor and the anchor cable 19 cooperate to position the floating platform 1 at the working position at sea;

[0059] The underwater heat dissipation cabin includes a cabin and a connecting hanger 4; the cabin is used to place computers and supporting equipment, and the cabin shell is made of heat-conducting materials, which provide heat conduction and cooling for the computer on the seabed; the passage 5 is a cylindrical structure, and the passage 5 includes a stairwell, an elevator shaft, and a communication pipeline, and the passage 5 is integrated with the underwater heat dissipation cabin; the passage 5 passes through the telescopic opening on the floating platform 1 and is connected to the floating platform 1; the staff enters the passage 5 through the door 11 at the upper end of the passage 5 and enters the underwater heat dissipation cabin from the door at the lower end of the passage 5; the passage 5 is used to transport electronic equipment, cables and materials from the floating platform 1 to the underwater heat dissipation cabin; the cables and optical fibers connecting the underwater heat dissipation cabin equipment pass through the communication pipeline in the passage 5 to the floating platform 1 and are connected to the equipment on the floating platform 1; the underwater heat dissipation cabin is suspended below the floating platform 1 through the connecting hanger 4. Specifically, the stairwell is an elevator shaft, and the staff enters the passage 5 through the elevator.

[0060] The underwater heat dissipation cabin includes at least two levels of heat dissipation cabins, specifically a first-level heat dissipation cabin 7 and a second-level heat dissipation cabin 8.

If it is a prefabricated slab, the prefabricated slab includes concrete, steel plate or composite material, etc. There is a groove under the hole where the slab and the wall are connected, which is convenient for locking nuts and bolts. Figure 5 As shown. There is a heat dissipation connection plate on the outside of the support wall extension, which is designed for opening and replacing heat dissipation components. The embedded bolts on the connection plate are as follows Figure 6 As shown, the heat sink assembly can be installed on the connecting plate, and the effect is as follows Figure 1 , Figure 2 , after a long time, you can remove and replace the heat dissipation components.

[0062] It also includes a submerged tank 15, which includes a tank shell, a supporting wall 17, a supporting foot 18 and a drainage system; the supporting wall is evenly arranged in the tank shell, and the supporting wall is provided with a plurality of upper and lower through holes 16, so that water and air can flow freely in the submerged tank 15; the drainage system includes a control module, an air compressor 21, a drain valve, an air valve and a gas pipeline 14; a drain port is provided at the bottom of the submerged tank 15, and the drain port is equipped with the drain valve shown; an air nozzle 22 is provided at the top of the submerged tank 15, and the air nozzle 22 is connected to the air compressor 21 in the adjacent heat dissipation tank through the gas pipeline 14 and the air valve; the air compressor 21 is a bidirectional air compressor 21; when it is necessary to raise the underwater height of the submerged tank 15 and the heat dissipation tank When the heat dissipation tank and the submersible tank 15 rise to the required height, the air compressor 21 is turned off, the air valve and the drain valve 23 are closed, and the ascending task is completed; when the heat dissipation tank and the submersible tank 15 need to sink, on the contrary, the air valve and the drain valve 23 are opened, the air compressor 21 is turned on to suck air into the submersible tank 15 in the reverse direction, the air pressure in the submersible tank 15 is negative to the water pressure outside the tank, and water enters the submersible tank 15 from the drain port 24; when the heat dissipation tank and the submersible tank 15 are lowered to the required water level, the air compressor 21 is turned off, the air valve and the drain valve 23 are closed, and the descending task is completed.

[0063] The contact part between the channel 5 and the telescopic opening is connected by an elastic sealing ring 12 and a rubber material 13; the channel 5, the channel 5 wall, the elastic sealing ring 12, the rubber material 13 and the stair steps of the floating platform 1 are arranged in sequence; the telescopic opening wall abuts against the deck of the floating platform 1. Figure 7 (Computers need a stable environment to work. When affected by waves underwater, floating platforms are greatly affected by waves at sea and will swing. The contact part between the channel and the telescopic opening is connected by an elastic sealing ring, and the influence of the swing of the floating platform on the underwater heat dissipation cabin can be reduced to a minimum. The channel and the telescopic opening are connected by elastic materials, which is equivalent to a sealed hole. People or things on the platform will not be transferred to the seabed through the telescopic opening.) There is a platform at the top of the channel. The staff enters the channel through the channel platform at the top of the channel. When the channel platform is raised or lowered, there are corresponding stairs to cooperate with it, which is convenient for people to enter and exit the channel. Figure 8 (The staircase surrounds the passage. When the passage rises, the platform at the top of the passage can be aligned with the stairs. Figure 8As the channel rises, you need to climb a few more steps to enter the platform at the top of the channel. When the channel descends, you need to go to the floating platform deck to enter the upper platform of the channel. The nearshore cooling cabin is directly sunk to the seabed, and the floating platform rises and falls with the tide. The channel is telescopically extended and retracted up and down at the telescopic opening, which does not affect the normal operation of the data cabin. The submerged tank mainly supports the underwater cooling cabin and assists the cooling cabin in raising and lowering the underwater height. The submerged tank includes a hull, supporting walls, supporting feet and a drainage system. Inside the cabin, the supporting walls are evenly arranged to support and reinforce the upper and lower plates. The supporting wall has multiple through holes, so water and air are not blocked in the cabin and can flow freely to fill the entire cabin. The drainage system includes a control module, an air compressor, a drain valve 23, an air valve D and a gas pipeline such as Figure 2A As shown. There is a drain port at the bottom of the cabin, and a drain valve is installed at the drain port. There is an air nozzle on the top of the cabin, and the air nozzle is connected to the air compressor in the first-level heat dissipation cabin through the gas pipeline and the air valve D. The air compressor is a bidirectional air compressor. When it is necessary to raise the underwater height of the submerged cabin and the heat dissipation cabin, open the air valve D, the air compressor inputs gas to the submerged cabin, and then open the drain valve D. After the gas enters the submerged cabin, it squeezes the water in the submerged cabin and drains to the seabed through the drain port. When the heat dissipation cabin and the submerged cabin rise to the required height, turn off the air compressor, close the air valve D and the drain valve 23, and the ascending task is completed. When the heat dissipation cabin and the submerged cabin need to sink, on the contrary, open the air valve D and the drain valve 23, open the air compressor to reversely suck air into the submerged cabin, the air pressure in the submerged cabin is negative to the water pressure outside the cabin, and water enters the submerged cabin from the drain port. When the heat dissipation cabin and the submerged cabin are lowered to the required water level, turn off the air compressor, close the air valve D and the drain valve 23, and the descending task is completed. The hanging piece of the submerged tank is changed into a hanging column, which is rigidly connected to the top plate of the heat dissipation tank at the bottom. The four corners of the floating platform corresponding to it are provided with telescopic openings. The upper end of the hanging column passes through the telescopic opening of the floating platform. The connection method is the same as the connection method between the channel and the telescopic opening. The hanging column and the telescopic opening are also flexibly connected through an elastic sealing ring. Fig. 9 shown.

[0064] The platform air cushion shock absorber includes a shock absorber shell, a ring-shaped air cushion, an umbrella-shaped hanging piece, an air pipe and a pulley block. The air cushion material is rubber or composite rubber with good air tightness. The air nozzle of the air cushion is connected to the air nozzle of the air cushion symmetrical with it through an air pipe. The top of the umbrella-shaped hanging piece is a circular cover plate, covering the ring-shaped air cushion. The bottom of the cover plate has a vertical cylindrical foot, and the lower end of the foot has a hanging hole such as Fig.11 As shown, the rope on the heat dissipation cabin passes through the lifting hole and is then hung under the floating platform. There is a lifting lug in the middle of the cover plate, and the rope hanging from the pulley block is connected to the lifting lug. (The floating platform will shake up and down due to the influence of wind and waves, while the seabed is much calmer than the sea surface. The underwater heat dissipation cabin is hung under the floating platform and its position is relatively stable. This technology can avoid being affected by the shaking of the floating platform. Working principle: The underwater heat dissipation cabin is in a stable state underwater. When the floating platform is tilted up on the left and lowered on the right, the pulley block is high on the left and low on the right. Fig.10As shown, since the heat dissipation cabin is relatively heavy, the umbrella-shaped hanging parts on the left and right sides are not affected and will not follow the pulley block to be higher on the left and lower on the right. If there is a strong wind and waves, the floating platform will sway violently. When the left side rises and falls, the bottom of the left shock absorber lifts the bottom of the rubber ring air cushion, and the rubber ring airbag is squeezed, generating high air pressure. At the same time, the right side descends, and the bottom of the right shock absorber lifts the rubber ring air cushion, which reduces the support force, and the rubber airbag generates negative pressure. The high pressure in the left airbag naturally flows to the right airbag through the air pipe, and the airbag is compressed on the left and expanded on the right, forming an adaptive horizontal balance. In this way, the upper pulley block balances the lifting force, and the lower rubber ring air cushion balances the supporting force, forming a rigid and flexible shock-absorbing effect.

[0065] The fan shaft is connected to the air compressor pump (the unipolar compression input is suitable for the air compressor pump at the fan end. The fan cabin space is limited and is not suitable for installing a multi-stage compression pump). When the blades rotate, the air compressor pump (hereinafter referred to as the air compressor pump) is rotated to generate high-pressure air. The output end of the air compressor pump is connected to the inlet end of the single-phase valve, and the outlet end of the single-phase valve is connected to the air pipeline. The one-way valve only outputs but does not input. The air inlet of the first-level storage compartment 25 is connected to the air pipeline through air pipe 1 and air valve 1. The air inlet of the first-level storage compartment 25 is connected to the air inlet of the second-level storage compartment 26 through air pipe 3 and air valve 3. The air inlet of the first-level storage compartment 25 is connected to the exhaust pipe through air pipe 2 and air valve 2, and the exhaust port of the exhaust pipe is on the ground. The air inlet of the second-level storage compartment 26 is connected through air pipe 4 and air valve 4 (the second-level storage compartment is not directly connected to the air pipeline, but is connected to air pipe 1 through air pipe 3 and then to the air pipeline. The exhaust pipe is also marked on the drawing as air pipe 4). The inlet of the low-pressure turbine is connected to the outlet of the cold-heat exchange cabin, the inlet of the cold-heat exchange cabin is connected to the gas pipeline through the air valve 5, and the outlet of the low-pressure turbine is connected to the exhaust pipeline. The inlet of the high-pressure turbine is connected to the outlet of the B cold-heat exchange cabin, the inlet of the B cold-heat exchange cabin is connected to the gas pipeline through the B switch air valve, and the outlet of the low-pressure turbine is connected to the exhaust pipeline. The output end of the compressor is connected to the inlet of the A cold-heat exchange cabin, and the outlet of the A cold-heat exchange cabin is connected to the gas pipeline. The water inlet of the first-stage storage tank 25 is connected to the outlet of the turbine through the water valve 2, and the inlet of the turbine extends to the outside of the equipment cabin through the first water valve and the pipeline; the water outlet of the first-stage storage tank 25 is connected to the water supply and drainage pipeline through the water valve 4. The water inlet of the second-stage storage tank 26 is connected to the outlet of the turbine through the water valve 3, and the water outlet of the second-stage storage tank 26 is connected to the drainage pipeline through the water valve 5.

[0066] During peak hours, open valve B, and the fan air compressor directly inputs high-pressure gas to the turbine to generate electricity. During low hours, close valve B, open valve 1, open water valve 2, and the fan air compressor inputs high-pressure gas to the first-stage storage tank 25 for energy storage. During low hours, if there is little or no wind, the air compressor can also work and input high-pressure gas to the first-stage storage tank. Fig.14.Drain the water in the first-stage storage tank 25 to the seabed. When the water level sensor senses that the water level in the first-stage storage tank 25 is lower than the safe water level, close the air valve 1 and the water valve 4, open the switch valve B, and the fan air compressor directly inputs high-pressure air to the high-pressure turbine, and the high-pressure turbine drives the generator to generate electricity. At the same time, open the air valve 2 and the water valve 5, and input the high-pressure gas in the first-stage storage tank 25 into the second-stage storage tank 26 through the air pipe 3. The high-pressure gas discharges the water in the second-stage storage tank 26 to the seabed. When the water level sensor senses that the water level in the second-stage storage tank 26 is lower than the safe water level, close the water valve 5. At this time, the air pressure in the first-stage storage tank 25 and the second-stage storage tank 26 is one level lower than the original air pressure in the first-stage storage tank 25, and becomes low pressure. During peak electricity consumption, because the air valve 2 is already opened, the spaces of the first-stage storage compartment 25 and the second-stage storage compartment 26 are connected, and the air valve 1 and the air valve 5 are opened. The first-stage storage compartment 25 and the second-stage storage compartment 26 input low-pressure air to the low-pressure turbine through the air valve 1 and the air valve 5, driving the low-pressure turbine to rotate the generator to generate electricity.

[0067] The power supply system is multi-energy complementary, including access to offshore power generation, wave power generation and solar power generation in three-dimensional space. Wind power is connected to the air compressor to produce high-pressure air, waves produce high-pressure air through the swinging air compression pump, and solar power generation is input into the air compressor to produce high-pressure air. The high-pressure air generated by wind, waves and solar energy is connected to the gas pipeline through a one-way air valve, which only outputs but does not input. Wind, waves and solar energy complement each other to produce the same high-pressure gas that is input into the deep-sea storage tank for energy storage. The air output is heated by the solar exposure heating cabin to improve the efficiency of high-pressure air input into the turbine.

[0068] Implementation at sea: 10 meters deep water is about 0.1Mpa, 100 meters deep water is about 1Mpa. Different heights have different water pressures. This scenario uses the natural slope near the coast. Figure 3 An energy storage system for an offshore data platform includes a storage tank, an equipment cabin, a heat exchange unit, an air expansion unit, an air compression unit, and the like. Fig.12 and Fig.14. The storage tank includes a tank body, an air inlet, an air outlet, a water inlet, and a water outlet. When the storage tank is sunk to the bottom of the sea, the drain outlet of the storage tank drains and stops draining water by controlling the drain valve 4. The air inlet of the storage tank is connected to the gas pipeline through the air valve 1. The air outlet of the storage tank is connected to the exhaust pipeline through the air valve 2. The equipment cabin includes a turbine and a generator. The turbine inlet draws water from outside the equipment cabin through the water valve 1. The turbine outlet is connected to the water inlet of the storage tank through the water valve 2. The turbine is coaxial with the generator, and the equipment cabin is close to the water inlet of the storage tank. The air compression unit is a unipolar high-pressure input (Note: unipolar high pressure is a period with relatively small pressure difference compared with the existing technology. For example, the existing technology has four-stage compression from 0.1Mpa to 140Mpa, and its last stage of compression may be 120Mpa to 140Mpa. When the air is input into the energy storage cabin, the air pressure ranges from 1 atmosphere to 140 atmospheres, and the difference is large. It requires at least 4 stages of compression, from low pressure to medium pressure, to medium and high pressure, and finally to high pressure before input into the energy storage cabin. Through technological innovation, this technology directly enters the high-pressure stage and inputs the energy storage cabin, and the energy storage process only requires one high-pressure stage). The heat exchange unit includes A and B cold and hot exchange cabins, and the cold and hot exchange cabins are divided into upper and lower layers. Fig.13 As shown. The heat exchange unit includes a cold heat exchanger cold storage tank and a heat storage tank. (Air generates heat during the compression process, and the cold and heat are separated by the cold heat exchange unit, and the heat is stored in the heat storage tank, and then the low temperature is circulated back to the cold heat exchanger. When air compression needs to generate electricity, the high-pressure gas needs to increase the temperature to improve the turbine power generation efficiency. At this time, the cold heat exchanger is used to reversely replenish energy to the turbine to increase the high-pressure gas input to the turbine). The outlet of the air compression unit is connected to the inlet of the lower layer of the A cold heat exchanger, and the outlet of the lower layer of the A cold heat exchanger is connected to the inlet of the air valve A, and the outlet of the air valve A is connected to the gas pipeline. The inlet of the upper layer of the A cold heat exchanger is connected to the outlet of the cold storage tank, and the outlet of the upper layer of the A cold heat exchanger is connected to the inlet of the heat storage tank. The inlet of the air expansion unit is connected to the outlet of the upper layer of the B cold heat exchange cabin, and the inlet of the upper layer of the B cold heat exchange cabin is connected to the gas pipeline through the air valve B, the inlet of the lower layer of the B cold heat exchanger is connected to the outlet of the heat storage tank, and the outlet of the lower layer of the B cold heat exchanger is connected to the inlet of the cold storage tank.

[0069] The storage compartment shall have at least two levels, such as Figure 3 As shown, the two levels are placed at different heights. Fig.12 As shown, the water inlet of the secondary storage tank 26 is connected to the outlet of the turbine in the equipment cabin through the water valve 3, and the drain outlet of the secondary storage tank 26 drains and stops draining by controlling the drain valve 5. The air inlet of the secondary storage tank 26 is connected to the gas pipeline through the air valve 3. The air outlet of the secondary storage tank 26 is connected to the exhaust pipeline through the air valve 4.

[0070] Example: For ease of understanding, the following calculations are based on integers. Assume that the altitude of the first-level storage compartment 25 is -1000 meters and the volume of the compartment is 100m 3, working water filling volume is 100m 3 The secondary storage tank 26 is at an altitude of -500 meters, with a tank volume of 100m3 and a working water filling volume of 100m 3 , water pressure at altitude -1000 meters is 10Mpa, 10Mpa1m 3 The power generation capacity of water is 2kW, the water pressure at an altitude of -500 meters is 5Mpa, 5Mpa1m 3 The power generation capacity of water is 1Kw.

[0071] The existing technology is to dilute and reduce the air pressure through multiple air storage tanks on the ground in multiple stages, assuming that the working air pressure of the turbine is 5Mpa.

[0072] During low electricity consumption, energy storage: Fig.12 .

[0073] Step 1. Open valve A and valve 1, start the air compression unit to input air greater than 10Mpa into the first-level storage compartment 25 (the air pressure greater than 10Mpa can discharge the water in the first-level storage compartment 25 to the outside). For ease of understanding, greater than 10Mpa, set to 10Mpa, open the water valve 4, and the high-pressure gas squeezes the water surface in the compartment from top to bottom (such as Fig.12 As shown in the figure, the water in the cabin is drained out through the drain port. When the water level pressure sensor senses that the water level drops to the safe water level line, 100m 3 water, stop the air compression unit, close the air valve A and the water valve 4, and the first-level storage compartment 25 forms a closed space. At this time, the 10Mpa high-pressure gas also fills 100m 3 space.

[0074] Step 2. Open the air valve 3, the space of the primary storage compartment 25 is connected to the space of the secondary storage compartment 26 through the air pipeline, and the high-pressure gas in the primary storage compartment 25 quickly enters the secondary storage compartment 26 through the air pipeline. Open the water valve 5, the high-pressure gas entering the secondary storage compartment 26 squeezes the water in the compartment from top to bottom, and the water in the secondary storage compartment 26 is discharged outward. When the water level pressure sensor of the secondary storage compartment 26 senses that the water has dropped to the safe water level, the amount of water discharged is exactly 100m 3 Since the total volume of the first-stage storage compartment 25 and the second-stage storage compartment 26 is 200m 3 , at this time, the air pressure in the first-stage storage compartment 25 and the second-stage storage compartment 26 is exactly 5Mpa. The drain valve 5 is closed, and the first and second-stage storage compartments 26 form a closed space. This technology reduces the process of releasing and degrading air pressure from multiple air storage tanks on the ground. The multi-stage storage compartments of this technology can reduce the air pressure to the pressure required for the turbine to work.

[0075] During peak hours of electricity consumption, power generation:

[0076] Turbine power generation: open the air valve B, and the 5Mpa air pressure in the first and second storage compartments 26 quickly enters the B cold and heat exchange compartment from the air valve B, and outputs high-pressure gas to the turbine through the B cold and heat exchange compartment to generate electricity. Wait until the high-pressure gas in the first and second storage compartments 26 is gradually discharged, and then close the air valve B.

[0077] Turbine power generation: Open the air valve 4 to connect the space of the secondary storage tank 26 with the offshore space.

[0078] Secondary storage tank 26 generates electricity: Open water valve 1 and water valve 3, seawater enters the turbine room through water valve 1, drives the turbine to rotate, and the turbine rotates the generator to generate electricity. After entering the turbine, seawater enters the secondary storage tank 26 through water valve 3. The water level in the secondary storage tank 26 rises and squeezes the air in the secondary storage tank 26 to be discharged to the sea through air valve 4. When the water level and air pressure sensor sense that the water level in the secondary tank is full, exactly 100m 3 , close the water valve 3 and the gas valve 4, and the water diversion and power generation stage of the secondary storage tank 26 ends.

[0079] The first-stage storage tank 25 generates electricity: while closing the water valve 3, open the water valve 2 and the air valve 2. At this time, the water in the turbine room passes through the water valve 2 and enters the first-stage storage tank 25, and the turbine continues to generate electricity. As the water level in the first-stage storage tank 25 continues to rise, the air in the tank is squeezed, and the air enters the exhaust pipe through the air valve 2 and is discharged to the sea. When the water level and air pressure sensor of the first-stage storage tank 25 senses that the water in the tank is almost full, close the air valve 2, and the air in the first-stage storage tank 25 is no longer discharged to the sea. Seawater continues to be transported to the first-stage storage tank 25 until the water level and air pressure sensor of the first-stage storage tank 25 senses that the water in the tank is full. When the air pressure rises to 10Mpa (in preparation for the subsequent unipolar input storage tank of the compressed air unit), the amount of water entering is exactly 100m 3 , close water valve 1 and water valve 2, and the turbine stops generating electricity.

[0080] Referring to the previous parameter calculation, we get:

[0081] First-stage storage tank 25 turbine power generation: 100m 3 / 10Mpa water, power generation 200Kw;

[0082] Secondary storage tank 26 turbine power generation: 100m 3 / 5Mpa water, power generation 100Kw;

[0083] Total 300Kw.

[0084] A multi-stage combination can be designed to be more optimized than a two-stage combination. For the sake of ease of calculation and understanding, it is temporarily assumed to be 6 stages, and the energy replenishment power generation data is obtained. The parameters are shown in the table:

[0085]

[0086] The shaft of the turbine blade on the fan is connected to the air compressor (the single-stage compression input is suitable for the air compression pump at the fan end. The fan cabin space is limited and it is not suitable for installing a multi-stage compression pump). The air compressor inlet has an air filter and directly inhales air from the outside. The outlet of the air compressor is connected to the inlet of the check valve, and the outlet of the check valve is connected to the gas pipeline, such as Fig.14 As shown. The air inlet of the first-stage storage tank 25 is connected to the gas pipeline through the air valve 1, and the air outlet of the first-stage storage tank 25 is connected to the exhaust pipeline through the air valve 2. The air inlet of the second-stage storage tank 26 is connected to the gas pipeline 1 through the air valve 3, and the gas pipeline 1 is connected to the inlet of the first-stage storage tank 25, and the air outlet of the second-stage storage tank 26 is connected to the exhaust pipeline through the air valve 4. The air inlet of the low turbine is connected to the gas pipeline through the air valve 5. The air inlet end of the low turbine is equipped with a heat exchange unit, and the high temperature of the compressed air is stored in the heat storage device through the heat exchange unit. The air outlet end of the turbine is connected to the exhaust port on the water surface through the exhaust pipeline. The low turbine shaft is connected to the generator through the clutch, and the other end of the engine is connected to the turbine through the clutch. The turbine includes turbine blades and a sealed turbine cabin. The inlet end of the turbine cabin is equipped with a switch water valve 1, and the turbine draws water through the water inlet outside the equipment cabin. The outlet of the turbine compartment is connected to the water inlet of the primary storage compartment 25 through the water valve 2. The primary storage compartment 25 can drain water to the outside of the compartment by opening the water valve 4, and the water flow can be blocked by closing the water valve 4. The outlet of the turbine compartment is connected to the water inlet of the secondary storage compartment 26 through the water valve 3. The secondary storage compartment 26 can drain water to the outside of the compartment by opening the water valve 5, and the water flow can be blocked by closing the water valve 5. The turbine, engine, heat exchange unit, low turbine, water valve, air valve and other equipment are installed in the closed equipment compartment.

[0087] The storage compartment has a main compartment and an auxiliary compartment. Fig.15 As shown, the main and auxiliary cabins are connected through upper and lower connecting ports, and the upper and lower connecting ports have flanges, which are connected by reinforcing members (such as bolts and nuts). After the upper connecting port is connected, the air in the two cabins can flow freely. After the lower connecting port is connected, the seawater in the two cabins can flow freely. There can be multiple auxiliary cabins, which can be connected to the space capsule after connection. Fig.16 .

[0088] The generator power output is connected to the adjustable load device through the controller. When the wind speed is lower than the normal cut-in wind speed, the controller is switched to the adjustable load device, and the generator output load is lowered to reduce the generator input torque, so that the low-pressure air generated by the fan air compressor can blow the turbine to generate electricity. (When the wind speed is very low, usually less than 3 meters per second, the fan does not rotate, but it is also a waste of energy. If there are 100 fans, the waste is huge. By lowering the load device, the generator output power is reduced, thereby reducing the torque required to rotate the generator. When the torque is reduced, the low-pressure air entering the turbine can also rotate to generate electricity, and the fan will not stop rotating.) Fig.14The equipment room includes a turbine, the turbine is connected to the generator through a clutch, and the turbine is connected to the generator through a clutch.

[0089] There are reinforcement plates in the storage compartment to strengthen the compartment structure. The reinforcement plates have holes in the upper, middle and lower parts to facilitate the circulation of water and air in the compartment. Fig.17 shown.

[0090] Workflow:

[0091] Compressed air energy storage and drainage energy storage:

[0092] Step 1. Open the air valve 1 and the water valve 4 at the same time, the turbine blades rotate the compressor to generate high-pressure gas which is input into the first-stage storage tank 25, and the water in the first-stage storage tank 25 is squeezed out from the drain port 1;

[0093] Step 2. When the water level pressure sensor senses that the water level in the first-stage storage tank has dropped to a safe level, the air inlet valve 1 and the water valve 4 are closed at the same time, and the air valve B is opened. At this time, the high-pressure gas generated by the fan is directly transmitted to the high-pressure turbine through the gas pipeline, and the high-pressure turbine rotates the generator to generate electricity. Fig.14 As shown (Note: There is an adaptive phenomenon when the fan is connected to the air compressor. For example, when the working pressure of the air compressor remains unchanged, the wind speed is small, the energy is small, and the blades rotate slowly; the wind speed is large, the energy is large, and the turbine blades rotate quickly.)

[0094] Step 3. Open the air valve 3 and the water valve 5 at the same time, and the high-pressure gas in the primary storage compartment 25 is input into the secondary storage compartment 26 through the gas pipeline 3, squeezing the water in the secondary storage compartment 26 out of the drain port 2. When the water level pressure sensor senses that the water level in the secondary storage compartment has dropped to a safe water level, the water valve 5 is closed at the same time, and the secondary storage compartment 26 no longer drains water. At this time, the air pressure in the secondary storage compartment 26 is reduced by one level, and the air compression energy storage and water discharge energy storage are completed.

[0095] During low electricity consumption: When the turbine blower inputs high-pressure air to the first-stage storage compartment 25, the air compression unit can be turned on at the same time, and the air valve A can be opened. The air compression unit and the wind force simultaneously input high-pressure air to the first-stage storage compartment 25, because the high-pressure air generated by the air compression unit and the high-pressure air generated by the wind force are of the same level. When the energy storage of the first-stage storage compartment 25 is completed, the air compressor and the air valve A are closed at the same time.

[0096] Power Generation:

[0097] Step 1. The low turbine is connected to the generator through the clutch, and the air valve 1 and the air valve 5 are opened. The high-pressure gas in the secondary storage compartment 26 and the primary storage compartment 25 is transported to the low turbine, driving the low turbine to rotate the generator to generate electricity. When the high-pressure gas in the primary storage compartment 25 and the secondary storage compartment 26 is exhausted, the water level pressure sensor senses that the air pressure in the two compartments is the same as the external air pressure, and closes the air valve 1, the air valve 3 and the air valve 5, ending the low turbine power generation, and the low turbine is separated from the generator through the clutch;

[0098] Step 2. The turbine is connected to the generator through the clutch, and the air valve 4 and the water valve 3 are opened. The water valve 1 is opened, and the deep sea water enters the turbine from the water inlet, and then enters the secondary storage tank 26 through the water valve 3. The deep sea water pressure is high, and it enters the turbine to drive the turbine to rotate the generator to generate electricity. When the water level pressure sensor senses that the water level in the secondary storage tank 26 has reached the highest water level, the water valve 3 is closed, and the air valve 4 is closed to end the water inlet to the secondary storage tank 26 to generate electricity.

[0099] Step 3. Close the water valve 3 and open the water valve 2 and the air valve 2 at the same time. At this time, the water from the turbine enters the first-stage storage tank 25 through the water valve 2, and the air in the first-stage storage tank 25 is exhausted to the exhaust port through the air valve 2.
