Abstract
Description
[Revised from Detailed Rule 26 to 29.04.2025] Deep-water caisson circulating water intelligent power generation system Technical Field
[0001] The invention relates to the field of power generation technology, which involves environmentally friendly, clean energy and infinite circulation. Background Technology
[0002] Against the backdrop of increasingly severe global climate change and energy crisis, finding sustainable and efficient clean energy solutions has become an urgent priority for human development. The deep-water well circulating water intelligent power generation system, as a groundbreaking invention, offers new possibilities for global clean energy development with its unique operating mechanism and broad application prospects. This article will elaborate on the significant implications of this patent for the world's clean energy development from multiple dimensions, including technical principles, resource potential, environmental benefits, and economic benefits. Technical issues
[0003] The potential energy generated by a single pumping operation is used sequentially by multiple hydroelectric generators. It fully utilizes atmospheric pressure, gravitational acceleration, a variable-diameter pipe (gradually changing from a large to a small diameter) connected to the water riser, and the siphon principle to create a perfect combination of upward pressure, downward push, and upward pull. See Figures 1, 2, 3, and 4. Technical solutions
[0004] The core of the deep-water caisson circulating water intelligent power generation system lies in its unique operating mechanism. The potential energy generated by the system is sequentially utilized by multiple sets of hydro-turbine generators. Furthermore, placing the circulating water and hydro-generators on the water surface within the caisson effectively avoids the impact of harsh marine climates. Unlike traditional offshore wind or tidal power generation, this system is unaffected by extreme weather conditions such as wind, waves, and typhoons, enabling continuous and stable power generation 365 days a year. This stability not only improves power generation efficiency but also reduces equipment maintenance costs and the risk of failure. The caisson structure design allows the system to fully utilize the kinetic energy of the water flow, optimizing water circulation through an intelligent control system to maximize power generation efficiency. In addition, the system's modular design allows for flexible deployment at different depths, adapting to diverse geographical environments. This technological innovation opens up new pathways for the development and utilization of marine energy. Beneficial effects
[0005] Approximately 71% of the Earth's surface is covered by oceans, and the ocean's energy reserves far exceed those of land. The emergence of deep-water caisson circulating water intelligent power generation systems allows humanity to utilize this vast resource more efficiently. Compared to traditional dam-based hydroelectric power generation, this system does not require large-scale alterations to the natural environment, avoiding damage to the ecosystem. Simultaneously, the cyclical nature of ocean currents makes this resource virtually inexhaustible, providing a sustainable solution for global energy supply. Deploying this system 12 nautical miles from the coastline not only creates a "floating power generation Great Wall" but also effectively mitigates typhoon damage to coastal land. This dual benefit makes the system's application prospects particularly broad in coastal areas. Global climate change has become one of the greatest challenges facing humanity, and reducing carbon emissions is key to achieving carbon peaking and carbon neutrality goals. As a zero-emission clean energy technology, deep-water caisson circulating water intelligent power generation systems can significantly reduce dependence on fossil fuels and lower greenhouse gas emissions. Compared to thermal power generation, this system eliminates the need to burn fossil fuels, avoiding emissions of harmful gases such as carbon dioxide and sulfur dioxide. Compared to nuclear power, it avoids the risks of nuclear waste disposal and high-risk safety hazards. Compared to solar photovoltaic and wind power generation, it is not limited by weather or diurnal variations, providing a more stable power output. This environmental friendliness makes the system a powerful tool for addressing climate change. From an economic perspective, the deep-water caisson circulating water intelligent power generation system has significant cost advantages. First, the system's construction and maintenance costs are relatively low. The caisson structure simplifies construction, and modular components facilitate mass production and installation. Second, the system's operating costs are extremely low, relying primarily on the kinetic energy of natural water flow without requiring additional fuel input. Furthermore, the system's high efficiency and stability enable it to generate considerable economic benefits. Taking China as an example, large-scale deployment of this system in coastal areas could reduce coal consumption by millions of tons annually, saving billions of yuan in energy costs. Simultaneously, the system's promotion can drive the development of related industrial chains, create numerous job opportunities, and promote economic growth. Attached Figure Description
[0006] Figure 1.2: The structure is more complex than Figure 3.4, but it consumes less energy and has higher power generation efficiency. Maintenance costs are slightly higher than Figure 3.4. Suitable for deep-water marine wells. Figure 3.4: The structure is simple, with low and convenient maintenance costs. Energy consumption is slightly higher than Figure 1.2. Power generation efficiency is slightly lower than Figure 1.2. Suitable for high-well, low-water applications on land and in high-rise buildings. The best embodiment of the present invention
[0007] While the deep-water caisson circulating water intelligent power generation system has demonstrated enormous potential, its future development still requires further technological upgrades and global cooperation. For example, introducing artificial intelligence and big data technologies can optimize system operating efficiency and achieve more precise energy management. Simultaneously, strengthening international cooperation and sharing technological achievements and experiences can accelerate the global rollout of the system. Furthermore, governments and enterprises need to increase investment in this technology and formulate corresponding policy support to create a favorable environment for the system's research, development, and application. Only through multi-party collaboration can the potential of this technology be fully realized, driving a global clean energy revolution. Embodiments of the present invention
[0008] China currently leads the world in technology and experience in constructing marine reinforced concrete caissons. Utilizing these technologies and experiences, China can cooperate with countries around the world for mutual benefit, jointly developing inexhaustible clean energy resources and gradually phasing out environmentally damaging power generation methods. The construction of caisson power generation systems should begin along the coast and gradually extend to inland countries. For existing dammed hydroelectric power stations, such power generation caissons can be built upstream to compensate for insufficient power supply during dry seasons. New high-rise residential buildings can also incorporate these high-well, low-water caissons to achieve self-sufficiency in their electricity supply. Industrial applicability
[0009] Global Applicability: The ocean covers most of the Earth, especially in coastal areas, where the potential for ocean energy development is enormous. By constructing power grids 12 nautical miles from the coastline, not only can the energy needs of coastal areas be met, but clean electricity can also be provided to inland areas. Furthermore, it can mitigate the environmental damage caused by typhoons in coastal regions.
