Description

Technical Field

[0001] The present invention relates to the technical field of underwater data centers, and in particular to an ocean platform consisting of an underwater data center and offshore charging piles based on multi-energy complementary power supply. Background Art

[0002] The main problems encountered by existing data center heat dissipation are: environmentally unfriendly, traditional heat dissipation systems usually use fossil fuels and refrigerants, produce a large amount of carbon emissions and environmental pollutants, and have a negative impact on the environment; low energy efficiency, consume a lot of energy, lead to energy waste and high energy consumption and other problems. Submarine data centers use seawater for natural cooling, which reduces energy consumption and damage to the environment. The application of submarine data centers is in line with my country's dual carbon development goals and new data center development strategy.

[0003] At present, the development of marine space generally has the problems of single function and fragmented resources. The traditional model often disperses energy facilities, communication equipment and marine infrastructure: offshore wind power and photovoltaic systems independently occupy the surface sea area, charging piles and navigation facilities are scattered near the coast, and submarine data centers are buried deep in the seabed and operate in an isolated island. This fragmented development not only leads to low efficiency in the use of sea areas, but also lacks coordination between different energy systems. Independently operated energy systems are difficult to complement each other for peak regulation, and a large amount of low-temperature waste heat and renewable electricity are not recycled. At the same time, the value of the three-dimensional space of the sea area is far from being released. There is a lack of functional connection and resource sharing in the vertical dimension from the sea surface to the seabed, which not only causes redundant investment in infrastructure, but also limits the comprehensive benefits of the marine economy. The wind speed at sea is significantly affected by weather systems and seasonal changes. The single offshore wind power supply system is affected by the special natural environment and extreme weather at sea, and the power generation is unstable, which will have a significant impact on the electricity demand at sea. In addition, for submarine data centers, it is necessary to ensure the stability and continuity of the central energy supply to avoid data loss and damage. Submarine data centers use seawater for natural cooling, which is one of the reasons for their high energy efficiency. However, the cooling process generates a large amount of waste heat, which is currently usually discharged directly into the ocean, resulting in energy waste.

[0004] In summary, the technical problems existing in the above-mentioned existing technologies, such as the single function of ocean space, fragmented resources, and inability to utilize waste heat, have hindered the green and sustainable development of submarine data centers.

[0005] This shows that the prior art needs to be further improved. Summary of the invention

[0030] The present invention proposes an offshore platform consisting of a submarine data center and offshore charging piles based on multi-energy complementary power supply. In order to make the advantages and technical solutions of the present invention clearer and more specific, the present invention is further described below in conjunction with specific embodiments.

[0031] The main technical concept of the present invention is to improve the technical problem of the existing technology of single offshore power generation, adopt offshore wind power devices, wave power generation devices, photovoltaic power generation devices and tidal power generation devices, and innovatively construct a "wind-light-wave-tidal" hybrid energy matrix and a three-dimensional space coordination system. Through the transformer station 14, the multi-voltage level energy coupling of the wind power converter 11, the wave power regulator 12, the photovoltaic MPPT controller 9 and the tidal power PWM rectifier 10 is realized. The collected electric energy simultaneously maintains the normal operation of the offshore charging pile and the submarine data center cabin 19, and the energy allocation room 8 is used to dynamically adjust the energy ratio. By designing the data center waste heat feedback heat pump system, the waste heat generated by the cooling of the submarine data cabin is converted into heat energy by the heat pump unit 15 and transported to the micro-pipes of the photovoltaic backplane and the heat conduction pipes 21 of the charging pile 7. At the same time, the dynamic allocation system is designed to realize the reasonable distribution of heat energy and the recovery and utilization of heat.

[0032] Combine the following Figure 1 and Figure 2 The present invention is further described.

[0033] The present invention is based on an offshore platform composed of a submarine data center and offshore charging piles powered by multiple energy sources, including a multiple energy source complementary power generation system, an offshore platform 3, a submarine data center and a protection system.

[0034] The submarine data center includes a submarine data center cabin 19 and an energy storage cabin 18 located nearby; the submarine data center cabin 19 includes a cabin body and a server located inside the cabin body, and its structure and use principle can be realized by referring to the existing technology.

[0035] The energy storage cabin 18 and the cabin body are both made of high-strength steel, and the structures are both sealed pressure vessels. For corrosion resistance, polyurea coatings can be applied on the outer wall of the cabin to increase the service life.

[0036] The multi-energy complementary power generation system described in the present invention includes a solar energy collection device 4, an offshore wind power collection device 2, a wave energy collection device 1 and a tidal energy collection device 5. The solar energy collection device 4 and the offshore wind power collection device 2 are located on the top of the offshore platform 3, the wave energy collection device 1 is located within a certain sea area outside the offshore platform 3, and the tidal energy collection device 5 is located near the submarine data center. Through the cooperation of the power generation devices at the top, middle and bottom layers, the "wind-light-wave-tidal" multi-energy complementarity is realized, the dependence on a single energy source is reduced, and the normal operation of the submarine data center is guaranteed.

[0037] Specifically, the solar energy collection device 4 is erected on the top of the offshore platform 3 through the support column 6, and is inclined to facilitate lighting of the offshore platform 3. The solar energy collection device 4 is connected to the offshore power station 13, which collects solar energy when the sun is sufficient during the day, converts the solar energy into electrical energy, and stabilizes the voltage of the electrical energy through the photovoltaic MPPT controller 9 of the offshore power station 13, and then increases the voltage to a daily voltage that can be used through the transformer station 14, which is used by the offshore platform 3 and the submarine data center cabin 19, and the surplus energy is stored in the offshore power station 13.

[0038] The offshore wind power collection device 2 is connected to the offshore power station 13. It collects wind energy when the sea breeze blows the blades to rotate, converts the wind energy into electrical energy, and stabilizes the voltage of the electrical energy through a wind power converter 11 arranged in the floating body of the offshore wind power collection device 2. The voltage is then increased to a usable daily voltage through a transformer station 14 for use by the offshore platform 3 and the submarine data center cabin 19, and the remaining energy is stored in the offshore power station 13.

[0039] The wave energy collection device 1 is connected to the offshore power station 13. It collects wave energy when ocean waves rise, converts the wave energy into electrical energy, and stabilizes the voltage of the electrical energy through the wave energy stabilizer 12 of the offshore power station 13. The voltage is then increased to a usable daily voltage through the transformer station 14 for use by the offshore platform 3 and the submarine data center cabin 19. The remaining energy is stored in the offshore power station 13.

[0040] The tidal energy collection device 5 is arranged at the water inlet 22 and the water outlet 23, and is connected to the energy storage cabin 18 through a submarine cable. The tidal energy collection device 5 collects tidal energy during high tide and low tide, converts the tidal energy into electrical energy, and then stabilizes the voltage through the PWM rectifier 10, and then increases the voltage to a daily voltage that can be used through the transformer station 14, which is used by the offshore platform 3 and the submarine data center cabin 19, and the remaining energy is stored in the energy storage cabin 18. In order to use electricity later, the power consumption of the entire cooling system is reduced; at the same time, the water circulation and flow within the submarine data center is maintained to take away part of the heat generated by the submarine data center.

[0041] The submarine data center cabin 19 is protected by a protection system. Specifically, the protection system includes a rectangular structure formed by two L-shaped protective dikes 24. The two L-shaped protective dikes 24 just surround the periphery of the submarine data center cabin 19 and the energy storage cabin 18. A water inlet 22 and a water outlet 23 are respectively designed at the two diagonals of the rectangular structure. Seawater flows through the entire submarine data center cabin 19 through the water inlet 22 and then flows out through the water outlet 23, ensuring that the submarine data center cabin 19 is in full contact with the seawater and achieves a heat dissipation effect.

[0042] The offshore platform 3 includes a charging pile 7, an energy allocation room 8, an offshore power station 13, a transformer station 14 and a data center waste heat feedback heat pump system. The data center waste heat feedback heat pump system is used to recover the heat energy generated by the heat dissipation of the submarine data center and apply it to the back of the solar energy collection device 4. It specifically includes: a heat pump unit 15, a water pump 16, a drainage pump 17, a pipeline 20, a heat conduction pipeline 21, and a heat conduction micro-pipeline 25. Two pipelines 20 are arranged, one of which connects the heat pump unit 15 with the water pump 16 and the drainage pump 17, and the other is connected to the water pump 16 alone and penetrates deep into the seabed. The pipeline connected to the drainage pump 17 is below the sea surface. The water pump 16 extracts seawater around the submarine data center cabin 19 and transports it to the heat pump unit 15 through a pipeline. The heat pump unit 15 converts the heat energy and transports it to the heat conduction micro-pipeline 25 and the heat conduction pipeline 21 to realize the utilization of waste heat from the submarine data center.

[0043] Combination Figure 3 and Figure 4 As shown, the heat-conducting pipe 21 is installed on the back of the solar energy collection device 4. The heat-conducting pipe 21 is respectively an insulating pipe 212, a micro heat-conducting pipe 211 and a closed heat-conducting pipe 213 from the outside to the inside. The heat-conducting micro-pipe is nested in the line connected to the charging pile 7 to play the role of protection, heat preservation and heating. The heat-conducting micro-pipe 25 is arranged in a spiral shape on the back of the photovoltaic panel of the solar energy collection device 4 to achieve heat preservation and heating of the photovoltaic panel. The heat pump unit 15 is used to pump seawater with waste heat to the heat pump unit 15 to convert heat energy and supply it to the heat-conducting pipe 21 of the photovoltaic backplane, so as to prevent the photovoltaic panel from frosting in winter and realize the antifreeze of the charging pile 7, thereby improving the power generation efficiency of the power generation equipment, realizing the utilization of waste heat and improving the utilization rate of energy.

[0044] The energy allocation room 8 is set on the offshore platform 3 to realize the intelligent allocation of energy. An intelligent energy management and dispatching system is introduced to monitor and optimize energy distribution in real time to ensure the efficient operation of each module. When the charging pile 7 is in an idle state, the electric energy is first supplied to the submarine data center, and the remaining energy is put into the energy storage cabin 18 located on the seabed. When the charging pile 7 is in a working state, the energy is allocated to the charging pile 7 and the submarine data cabin at the same time. If the energy is insufficient, the energy storage cabin 18 is allocated to supplement the power supply.

[0045] The offshore power station 13 and the energy storage cabin 18 are both equipped with the function of storing electric energy. The offshore power station 13 can stabilize and transform electric energy at the same time, and the energy storage cabin 18 mainly realizes the stable power supply to the submarine data center. The dual power storage equipment can save the use of submarine cables and ensure the stable operation of the submarine data center.

[0046] Preferably, the charging piles 7 are arranged on both sides of the offshore platform 3 away from the protective dike 24 and the wind power device to facilitate the entry and exit of ships and other equipment. Several groups of offshore charging piles 7 can be arranged on the offshore platform 3 according to actual needs.

[0047] In summary, the present invention adopts an innovative marine space stratification model to achieve full utilization of space and energy; it adopts multi-energy complementary power supply to reduce dependence on a single energy source, improve energy utilization efficiency, and reduce the risk of power outages. At the same time, an intelligent energy management and scheduling system is introduced to monitor and optimize energy distribution in real time to ensure efficient operation of each module. When the charging pile 7 is in an idle state, electric energy is first supplied to the submarine data center, and the remaining energy is placed in the energy storage cabin 18 located on the seabed. When the charging pile 7 is in working condition, energy is allocated to supply the charging pile 7 and the submarine data center cabin 19 at the same time. If the energy is insufficient, the energy storage cabin 18 is allocated to supplement the power supply; and the present invention innovatively designs a heat recycling system, which uses the submarine data cabin to cool waste heat and recycles the waste heat.
