Description

Technical Field

[0001] This invention belongs to the field of hydropower generation technology, specifically a low-cost modular intelligent hydropower floating power generation system. Background Technology

[0002] Under the global trend of energy structure transformation towards green and low-carbon development, hydropower, as a technologically mature and stable renewable energy utilization method, is an important component of building a clean energy system. Traditional stationary hydropower stations are limited by topography, ecological environment, and other conditions, resulting in long construction periods, high investment costs, and significant impacts on river ecosystems, making it difficult to widely cover dispersed water areas such as small and medium-sized rivers and reservoir tributaries. Hydropower is the engineering technology and science that studies the conversion of water energy into electrical energy. It is an important part of the modern power industry system and a major way to develop and utilize water resources on a large scale. Its basic principle is to utilize the water level difference in natural rivers, lakes, and other water bodies, or to create head through damming, to convert the gravitational potential energy contained in the water body into kinetic energy, driving the turbine to rotate, and then driving the coaxially connected generator to generate electricity.

[0003] However, existing hydropower generation technologies generally suffer from shortcomings such as high cost, difficult maintenance, low energy efficiency, and poor ecological adaptability. They mostly adopt customized high-end materials and integrated structures, and production, transportation, and assembly rely on large equipment and professional personnel. At the same time, most platforms adopt a closed design, which can easily cause water accumulation and ecological barriers. The anchoring and buoyancy stabilization mechanisms are complex and expensive, making it difficult to flexibly adapt to different water environments and power generation scale adjustment needs.

The front-mounted floating debris removal unit continuously delivers clean water to the power generation unit through graded interception and gravity collection, preventing debris from entangled in the turbine or blocking the duct, ensuring stable operation of the turbine and generator, and reducing power generation interruptions due to malfunctions. The intelligent control unit monitors the turbine angle and power generation status in real time, automatically adjusting the turbine blade angle through a purely mechanical linkage mechanism, ensuring the turbine always maintains the optimal energy capture posture and further improving the stability of power generation efficiency. This invention utilizes untapped resources without intercepting the flow of water. The device employs standardized modular assembly to form a large-scale green power station. The turbine blades can automatically adjust their angle to stabilize power generation efficiency and allow fish to navigate. A pre-positioned debris interception and removal unit uses hydrodynamic energy and automated equipment to automatically collect debris ashore. Artificial intelligence technology enables the entire system to operate fully automatically without human intervention. This invention integrates clean energy power generation, river ecological management, fish protection, and safe navigation. It can be deployed on a large scale, possessing extremely high economic and ecological value, while also being very low in cost.

[0016] 2. In this invention, the open platform structure and non-interceptive design allow for natural flow of river water, avoiding obstruction and siltation of the aquatic ecosystem, and adapting to natural aquatic environments with different flow rates and water levels.

A low-cost modular intelligent hydrodynamic floating power generation system as described in claim 1, characterized in that: It also includes a quick-assembly mechanism, consisting of industrially mass-produced stainless steel clips and waterproof plugs; It also includes a low-cost anchoring and buoyancy stabilization mechanism, which uses general-purpose iron anchors and nylon anchor chains as anchoring components, and uses general-purpose plastic water tanks on the platform for ballast stabilization, adjusting the platform's attitude by manually adding or releasing water.

10. The control method for a low-cost modular intelligent hydrodynamic floating power generation system as described in claim 1, characterized in that: include: (1) Several standardized power generation and pollution control modules are spliced ​​together to form an array power station, which is anchored and fixed in non-navigable waters; (2) The fully automated control system automatically adjusts the turbine blade angle according to the water flow speed to maintain the stability of the force area and power generation, and activates the fish passage mode; (3) The debris interception and cleaning unit automatically intercepts garbage at the front end of the water inlet and completes the salvage, transportation and shore-landing operations.
