Description

Technical Field

[0001] The present invention relates to the technical field of ocean power generation, and in particular to a combined submarine data center hydroelectric power generation device and a construction method thereof. Background Art

[0002] According to data from the "China Electricity Development Report 2023", the proportion of traditional thermal power generation in the country is still as high as over 60%. This mode of power generation has a significant impact on the environment. It not only consumes a large amount of fossil fuels, but also produces a large amount of greenhouse gases and other pollutants, which has a negative impact on global climate change and environmental quality.

[0003] At the same time, the ocean covers about 71% of the earth's surface, providing great potential for the use of ocean energy for power generation. However, existing wave power generation equipment is mainly divided into two categories: sea surface type and submarine type. Sea surface power generation equipment uses the tidal energy of the sea surface to generate electricity. It is usually deployed near the coastline for daily monitoring and maintenance. However, this convenience is accompanied by high construction costs, especially the investment in embankment construction; coupled with the instability of sea surface waves, the energy conversion efficiency fluctuates, affecting the continuity and stability of power generation efficiency; and the equipment is directly facing the harsh environment of the ocean for a long time, such as continuous wave beating, strong wind invasion and salt spray corrosion, which accelerates the loss and aging of the equipment. In contrast, submarine power generation equipment, relying on its advantages of utilizing the stability of submarine currents and high energy density, is mostly located in deep water areas, effectively avoiding the impact of irregular movement of sea surface waves on power generation efficiency and the loss of equipment due to extreme climatic conditions on the sea surface, reducing interference with the sea surface ecosystem, reflecting a more environmentally friendly and sustainable development concept, and is an important development direction for wave power generation technology in the future. However, the biggest problem facing existing submarine power generation equipment is the difficulty in installation and maintenance. In addition, the laying of deep-sea cables requires crossing complex terrain and submarine obstacles, which makes the construction difficult and costly.

[0004] Therefore, developing an undersea power generation device that can effectively capture and utilize the stable energy of undersea waves to generate electricity and has relatively low installation and maintenance difficulty is a difficult problem in the current development of marine power generation technology. Summary of the invention

[0005] In view of the deficiencies mentioned in the above technical background, an object of the present invention is to provide a combined submarine data center hydroelectric power generation device and a construction method thereof.

The turbine is provided with a turbine transmission gear, the turbine transmission gear is gear-connected with one end of the transmission shaft, and the other end of the transmission shaft is connected to a rotor provided in the generator. The transmission shaft converts the rotational mechanical energy of the turbine into the rotational mechanical energy of the rotor. The rotational mechanical energy of the rotor generates an induced electromotive force under the action of a stator provided in the generator, thereby converting it into electrical energy.

[0012] As a preferred technical solution of the present invention, a track is installed on the upper surface of the fixed frame, and the turbine generator is installed on the track through a connecting piece. The connecting piece is provided with a telescopic device and a rotation positioning device. The telescopic device is used to adjust the vertical displacement of the turbine generator, and the rotation positioning device is used to adjust the rotation angle of the turbine generator relative to the fixed frame. The track, the telescopic device and the rotation positioning device are all electrically connected to the controller.

[0013] Furthermore, the outer wall of the turbine generator is provided with a plurality of flow sensors for detecting seawater flow and at least one angle sensor for detecting the angle of the turbine generator, and both the flow sensor and the angle sensor are electrically connected to the controller.

[0014] As a preferred technical solution of the present invention, the submarine data center is installed on both sides of the corridor structure, one end of the corridor structure is set on the seabed, and the other end is connected to the land. The submarine data center and the corridor structure constitute a combined submarine data center.

[0015] A method for constructing a combined submarine data center hydroelectric power generation device of the present invention comprises the following steps:

[0016] S1 Design Planning: Simulate the water flow velocity in the installation area of ​​the combined submarine data center according to the sea area working conditions, design the structure and size of the hydroelectric power generation device, and determine the installation height of the hydroelectric power generation device and the retractable scale of the telescopic bracket;

[0017] S2 prefabricated combined submarine data center: the combined submarine data center is constructed by factory prefabrication, and the maintenance elevator room is embedded in a preset position. The size of the maintenance elevator room is designed to be 1.5 to 2.5 times that of the hydroelectric power generation device;

[0021] As a preferred technical solution of the present invention, the hydroelectric power generation device is equipped with a transformer and an electricity storage device.

[0022] In summary, the beneficial effects of the present invention are:

[0023] 1. The present invention arranges hydroelectric power generation devices on the corridor structure of the submarine data center, making full use of the natural phenomenon of a sharp increase in water flow velocity in a local area due to the water-blocking effect of the submarine structures, and arranges the hydroelectric power generation devices at the location where the flow velocity increases, so as to utilize the kinetic energy resources of seawater with maximum efficiency. Compared with directly arranging the hydroelectric power generation devices on the seabed, the present invention not only utilizes the phenomenon of increased flow velocity caused by the submarine structures to generate electricity, but also can more effectively capture water flow energy and improve the power generation efficiency of the turbine generator; it also does not require additional submarine land excavation or occupation, and the hydroelectric power generation devices are installed in the corridor structure on land, and are sunk to the seabed together by barges, which greatly reduces the construction difficulty and cost, and reduces the interference with the marine ecological environment; in addition, the cables can be laid in the corridor structure, which helps to reduce the difficulty of laying deep-sea cables, reduces the risk of energy supply interruption caused by cable damage, and ensures the stability and reliability of energy supply.

[0024] 2. By embedding a maintenance elevator room on the corridor structure, when the hydroelectric power generation device needs to be repaired, the hydroelectric power generation device can be retracted into the maintenance elevator room and the water can be pumped out. Maintenance personnel can enter the maintenance space directly from land without the need for additional underwater operation equipment, which further reduces the difficulty and cost of maintenance, makes the maintenance of the power generation device more convenient, and improves the maintainability of the equipment.

[0025] 3. The present invention not only achieves efficient self-sufficiency in energy, but also promotes flexible allocation and storage of energy by arranging hydroelectric power generation devices on the corridor structure of the submarine data center. Specifically, the electric energy generated by the hydroelectric power generation device can be directly used for its own operation and maintenance, effectively reducing the loss of energy during conversion and transmission, significantly improving the overall energy utilization efficiency, and reducing dependence on external energy, enhancing the self-sufficiency and independence of the system; in addition, when the electric energy generated by the hydroelectric power generation device exceeds its own needs, the excess submarine power generation energy will be stored and reversely supplied to the city's electricity when needed, providing the city with stable and reliable green power support. When a large-scale failure occurs in the hydroelectric power generation device, the operation of the submarine data center is guaranteed by the city's power supply system to ensure the continuity and stability of the data center.

DETAILED DESCRIPTION

[0031] The specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments given here are only used to illustrate and explain the present invention, and cannot be used to limit the present invention.

[0032] It should be noted that many specific details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention may also have other implementations and variations thereof. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0033] like Figures 1 to 3 As shown, a combined submarine data center hydroelectric power generation device, the hydroelectric power generation device 1 is arranged on a corridor structure 3 for installing a submarine data center 2, the hydroelectric power generation device 1 includes a fixed platform 11, a telescopic bracket 12, a fixed frame 13, a plurality of turbine generators 14 and a controller (not shown in the figure), the fixed platform 11 is installed on the upper surface of the corridor structure 3, the telescopic bracket 12 is provided on the fixed platform 11, the top of the telescopic bracket 12 is fixedly installed with the fixed frame 13, the upper surface of the fixed frame 13 is provided with a plurality of turbine generators 14, the turbine generator 14 and the telescopic rod are electrically connected to the controller.

[0034] As a preferred embodiment of the present invention, a maintenance elevator room 4 for maintaining the hydroelectric power generation device 1 is embedded in the upper surface of the corridor structure 3, and the maintenance elevator room 4 includes an elevator room body 41 and an elevator door 42, and the elevator door 42 is embedded in the upper surface of the corridor structure 3, and the elevator room body 41 is fixedly installed on the lower surface of the elevator door 42 and surrounded by the elevator door 42 to form a maintenance space 43, and a lifting component 44 is fixedly provided inside the elevator room body 41, and a maintenance door 45 is provided on the side wall, and the free end of the lifting component 44 is connected to an elevator plate 46, and the hydroelectric power generation device 1 is fixedly installed on the upper surface of the elevator plate 46, and the lifting component 44 and the elevator door 42 are both electrically connected to the controller.

[0035] When the hydroelectric power generation device 1 is in use, the controller controls the elevator door 42 to open an appropriate distance, drives the lifting assembly 44 to extend, and drives the elevator plate 46 to move upward to a position where the horizontal height of the elevator plate 46 is consistent with the elevator door 42. At this time, the controller will act on the elevator door 42 again, so that it approaches the elevator plate 46 and finally fits tightly with the elevator plate 46 to form a sealed barrier, effectively isolating the external seawater, and the entire hydroelectric power generation device 1 will work on the upper surface of the corridor structure 3; when the hydroelectric power generation device 1 needs to be inspected or repaired, the controller releases the clamping pressure of the elevator door 42 on the elevator plate 46, releases the connection between the two, and drives the lifting assembly 44 to shrink and drive the elevator plate 46 to move downward until the hydroelectric power generation device 1 falls into the elevator room body 41. At this time, the controller drives the elevator door 42 to close, so that it surrounds the elevator room body 41 to form a closed maintenance space 43, and uses a water pump to evacuate the water in the maintenance space 43, providing a safe environment for maintenance personnel to maintain and repair the hydroelectric power generation device 1, which not only ensures the convenience of maintenance, but also guarantees the safety of maintenance personnel.

[0036] Furthermore, water stoppers (not shown) are provided around the elevator plate 46 and at the door gap of the elevator door 42, and the elevator door 42 is a push-pull type.

[0037] When the lifting plate is raised to the same height as the elevator door 42, the push-pull elevator door 42 is closed inwards and combined with the lifting plate water stopper to achieve a waterproof effect.

[0038] Furthermore, the fixed platform 11, the telescopic bracket 12, the fixed frame 13 and the maintenance elevator room 4 are all made of carbon fiber composite material.

[0039] As a preferred embodiment of the present invention, the turbine generator 14 includes a turbine (not shown in the figure), a transmission shaft 141 and a generator 142. The turbine is provided with a turbine transmission gear 143, and the turbine transmission gear 143 is gear-connected with one end of the transmission shaft 141. The other end of the transmission shaft 141 is connected to the rotor provided in the generator 142. The transmission shaft 141 converts the rotational mechanical energy of the turbine into the rotational mechanical energy of the rotor. The rotational mechanical energy of the rotor generates an induced electromotive force under the action of the stator provided in the generator 142, thereby converting it into electrical energy.

[0040] As the core part of the hydroelectric power generation device 1, the turbine generator 14 converts the kinetic energy of the fluid in the ocean into mechanical energy, and then converts it into electrical energy through the generator 142. When working, the turbine is provided with blades for capturing the kinetic energy of the water flow. When the water flow hits the blades of the turbine, the rotational motion of the blades converts the kinetic energy of the fluid into the mechanical energy of the turbine transmission gear 143. The meshing connection between the turbine transmission gear 143 and the transmission shaft 141 can be in the form of straight teeth, helical teeth or spiral teeth, depending on the design requirements and application scenarios. This meshing connection should allow the transmission shaft 141 to capture the rotational mechanical energy of the turbine and transmit it to the generator 142. Inside the generator 142, the rotation of the transmission shaft 141 drives the rotor, and through the principle of electromagnetic induction, alternating current is generated in the stator winding to convert mechanical energy into electrical energy, thereby achieving the purpose of hydroelectric power generation.

[0041] As a preferred embodiment of the present invention, a track 15 is installed on the upper surface of the fixed frame 13, and the turbine generator 14 is installed on the track 15 through a connecting piece. The connecting piece is provided with a telescopic device (not shown in the figure) and a rotation positioning device (not shown in the figure). The telescopic device is used to adjust the vertical displacement of the turbine generator 14, and the rotation positioning device is used to adjust the rotation angle of the turbine generator 14 relative to the fixed frame 13. The track 15, the telescopic device and the rotation positioning device are all electrically connected to the controller.

[0042] When the position and angle of the turbine generator 14 need to be adjusted, the controller sends a movement instruction to the track 15 and the telescopic device, and sends a rotation instruction to the rotation positioning device through an electrical signal. The movement instruction includes the direction and distance of movement, and the rotation instruction includes the direction and angle of rotation. After receiving the instruction, the mechanical structure connected to the track 15 starts to work, driving the turbine generator 14 to move to the correct position along the track 15, and the controller will lock the fixing mechanism on the track 15 to ensure that the turbine generator 14 is stably in the working position; the telescopic device extends or contracts the corresponding distance according to the instruction, and the vertical position of the turbine generator 14 is precisely adjusted in combination with the telescopic bracket 12. At the same time, the rotation positioning device will also rotate accordingly according to the instructions of the controller to achieve precise positioning of the turbine generator 14. This integrated adjustment system allows the turbine generator 14 to automatically optimize its position and angle under different marine conditions, thereby improving its operating efficiency and energy output. Through automated control and adjustment, the turbine generator 14 can continue to operate in the best state, maximize energy capture, reduce human intervention, and improve the safety and convenience of operation.

[0043] Furthermore, the outer wall of the turbine generator 14 is provided with a plurality of flow sensors for detecting seawater flow and at least one angle sensor for detecting the angle of the turbine generator 14, and both the flow sensors and the angle sensors are electrically connected to the controller.

[0044] As a preferred embodiment of the present invention, the submarine data center 2 is installed on both sides of the corridor structure 3. One end of the corridor structure 3 is set on the seabed and the other end is connected to the land. The submarine data center 2 and the corridor structure 3 constitute a combined submarine data center.

[0045] The submarine data center 2 is built on the seabed and connected to the land through the corridor structure 3, which provides maintenance personnel with the convenience of directly entering the seabed from the land to maintain and repair the data center, significantly reducing the time and difficulty required to reach the data center and reducing the risk of underwater operations, because maintenance personnel can work in a land-like environment instead of in more challenging underwater conditions; in addition, the submarine data center 2 uses seawater as a natural cooling source, effectively reducing the energy consumption required for cooling the data center. This natural cooling method not only supports higher power density, but also can stably provide powerful computing power. At the same time, the design of the submarine data center 2 saves precious land resources and places the data center in a location far away from human activity areas, providing a more stable and undisturbed working environment for the server.

[0046] The working principle of the hydroelectric power generation device of the present invention:

[0047] When the submarine current flows through the submarine corridor structure 3, the water flow speed will increase due to the obstruction of the corridor structure 3. This phenomenon is used to drive the turbine generator 14 in the hydroelectric power generation device 1 installed on the submarine corridor. When the accelerated water flow hits the blades of the turbine generator 14, the turbine starts to rotate, converting the kinetic energy of the water into mechanical energy. The turbine and the generator 142 are connected by a transmission shaft 141. The kinetic energy on the turbine is transmitted to the generator 142 through the transmission shaft 141. The generator 142 is equipped with a magnetic stator to generate a magnetic field. The transmission shaft 141 drives the rotor on the generator 142 to rotate and continuously cuts the magnetic flux lines to generate an induced electromotive force, thereby converting the kinetic energy of the water into electrical energy. Since the speed and direction of the submarine current may change with time and environmental conditions, the generated electrical energy may be unstable. By transmitting the generated electrical energy to the transformer through wires, the unstable electrical energy is converted into DC or AC with stable voltage, and the stable electrical energy is transmitted to the electrical energy storage device for energy storage, such as a battery or other power storage system, for subsequent use or integration into the power grid.

[0048] like Figure 4As shown, a method for constructing a combined submarine data center hydroelectric power generation device of the present invention comprises the following steps:

[0049] S1 Design planning: simulating the water flow velocity in the installation area of ​​the combined submarine data center 2 according to the sea area working conditions, designing the structure and size of the hydroelectric power generation device 1, and determining the installation height of the hydroelectric power generation device 1 and the retractable dimension of the telescopic bracket 12;

[0050] S2 prefabricated combined submarine data center 2: the combined submarine data center 2 is constructed in a factory prefabricated manner, and the maintenance elevator room 4 is embedded in a preset position. The size of the maintenance elevator room 4 is designed to be 1.5 to 2.5 times that of the hydroelectric power generation device 1;

[0051] According to the engineering requirements and the water flow and sediment conditions in the sea area, the structure and size of the corridor structure 3 and the submarine data center 2 are designed. The corridor structure 3 can be cast with reinforced concrete or steel shell concrete. When casting, pay attention to reserving space for the maintenance elevator room 4. After the casting is finalized, the maintenance elevator room 4 is constructed. The lifting component 44 of the maintenance elevator room 4 can be controlled by a combination of manual and electric methods. Manual control is mainly used when large-scale circuit problems occur, and electric control is used for daily operation.

[0052] S3 assembling and installing the hydroelectric power generation device 1: completing the assembly of the hydroelectric power generation device 1 in the factory and conducting a qualification inspection. The hydroelectric power generation device 1 that has passed the inspection will be installed on the elevator plate 46, and the corresponding cables will be laid to perform power transmission and control by the controller;

[0053] Each group of hydroelectric power generation devices 1 is an independent individual, and an independent control system is provided between it and the controller. When a hydroelectric power generation device 1 fails, it will not affect the normal operation of other devices, thus ensuring the maximum reliability and continuous power supply capability of the entire power generation system.

[0054] S4 Debugging and operation: The combined submarine data center 2 is transported to the designated installation area by a barge for installation. After all installations are completed, the city electricity is connected. The controller controls the lifting assembly 44 to drive the lifting plate to lift the hydroelectric power generation device 1 to a predetermined position and debug it to an operating state. During operation, the angle of the hydroelectric power generation device 1 is adjusted according to the water flow data obtained by real-time monitoring of the flow sensor so that it always faces the optimal water flow direction.

[0055] The electric energy generated by the hydroelectric generating device 1 is divided into two power supply systems, one is the power supply of the device itself, and the other is the urban power supply. The power supply of the device itself is mainly used for the daily operation monitoring of the hydroelectric generating device 1 to ensure that the hydroelectric generating device 1 has a stable and continuous power supply during the normal operation to support its various monitoring and adjustment tasks, such as flow monitoring, equipment status inspection, etc. When the external power grid fails or is unavailable, the hydroelectric generating device 1 can continue to operate by relying on the electric energy generated by itself, which enhances the self-sufficiency of the system and realizes efficient management and optimization of the power generation process. Urban power supply is mainly to store the excess electric energy or directly use it to supply the electricity demand of urban residents and industries when the electric energy generated by the hydroelectric generating device 1 exceeds its own power supply demand.

[0056] S5 Maintenance and inspection: When the hydroelectric power generation device 1 fails and needs maintenance, the controller retracts the hydroelectric power generation device 1 into the maintenance elevator room 4, uses a water pump to evacuate the water in the maintenance elevator room 4, and the staff enters from the maintenance door 45 to complete the inspection.

[0057] As a preferred embodiment of the present invention, the hydroelectric power generation device 1 is equipped with a transformer and an electricity storage device.

[0058] The hydroelectric power generation device 1 not only has the core function of converting submarine wave energy into electrical energy, but also integrates transformer and power storage equipment to form a complete power production and management system. The transformer equipment is responsible for boosting the electrical energy generated by the power generation device to a voltage level suitable for long-distance transmission to ensure efficient and safe power transmission; while the power storage equipment is used to store electrical energy when power demand is low or there is excess power generation so that it can be released when needed, thereby achieving smooth scheduling and supply of electrical energy, further improving the flexibility and reliability of the entire submarine power generation system.

[0059] It should be understood that the above-mentioned embodiments are one or more embodiments of the present invention, and there are many other embodiments and variations thereof based on the present invention; the variations and modifications made by ordinary technicians in this industry through the present invention without making pioneering innovations all fall within the scope of protection of the present invention.
