[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] The following describes in detail an embodiment of the present invention, a blade adjustment structure designed to finely adjust the turbine blades to better adapt to changing water flow conditions. This adjustment capability significantly improves turbine efficiency, enabling it to maintain optimal performance under varying hydraulic conditions. The core component of this structure is the turbine shaft 8, which is fixedly connected to the turbine 15 at one end. This design not only ensures turbine stability during operation but also enables direct and efficient power transmission to the entire system.

[0019] The other end of the turbine shaft 8 is connected to a precise adjustment mechanism 14. The main function of this adjustment mechanism 14 is to adjust the angle of the blades. By changing the angle of the blades, the working performance of the turbine can be optimized so that it can achieve the highest efficiency under different water flow speeds and directions. This adjustment mechanism allows the turbine to flexibly adjust the blades when facing different working conditions to adapt to changes in water flow, thereby improving the efficiency of energy conversion. Not only does it improve the adaptability and efficiency of the turbine, it may also reduce maintenance costs, because by adjusting the blade angle, the wear on the turbine caused by changes in water flow conditions can be reduced. This blade adjustment structure provides an effective solution for the efficient, stable and economical operation of the turbine.

[0020] Inside the adjustment mechanism 14, an adjustment worm 3 and a transmission worm wheel 5 are installed. The adjustment worm 3 is a very critical component in this adjustment mechanism. It has a spiral structural design, which enables it to convert rotational motion into linear motion, thereby achieving adjustment of the blade angle. The transmission worm wheel 5 is engaged with the adjustment worm 3, and its rotation can drive the adjustment worm 3 to perform linear motion. In order to ensure the stability and accuracy of the transmission worm wheel 5 during high-speed rotation, it is fixed to the inside of the turbine shaft 8 by a locating bearing 4. The design of the locating bearing 4 is to stably fix the transmission turbine 5 in the turbine shaft 8. It allows the transmission worm wheel 5 to rotate freely on the turbine shaft 8 while maintaining the accuracy of its position, which is crucial to ensuring the efficient operation of the entire system.

[0021] The blade adjustment structure of this utility model has significant benefits compared to existing technologies. It uses a worm gear mechanism to adjust the blades. Compared with the traditional oil pressure adjustment method, this design has significant improvements in economy, environmental protection and operational convenience.

[0022] First, in terms of economics, the worm gear design simplifies the entire adjustment system, reducing energy consumption and maintenance costs associated with the hydraulic system. Worm gear systems typically offer high transmission efficiency and a compact structure, which reduces material usage and overall costs. Furthermore, the self-locking nature of the worm gear mechanism improves system safety to a certain extent, reducing the risk of unplanned downtime due to hydraulic system failures, thereby lowering maintenance costs and improving power generation efficiency.

[0023] In terms of environmental protection, the worm gear mechanism does not rely on hydraulic oil, thus reducing the risk of oil leakage and potential water pollution. At the same time, because the worm gear mechanism has less wear and tear, the maintenance cycle is longer, and the frequency of part replacement is reduced, thereby reducing waste generation and meeting current environmental protection requirements.

[0024] Regarding operational convenience, the worm gear mechanism allows for manual or automatic rotation, driving the transmission worm gear to adjust the blades. This design simplifies the operation process, making blade adjustment more intuitive and convenient. Furthermore, the precise control capabilities of the worm gear mechanism make it easier to precisely adjust the blade angle, improving the turbine's operating efficiency and responsiveness.

[0025] The blade adjustment structure of the utility model adopts a worm gear mechanism, which not only improves the economy and environmental protection of the turbine, but also significantly improves the convenience of operation, providing a strong guarantee for the efficient and stable operation of the turbine.

[0026] The design of this blade adjustment structure not only improves the adaptability and power generation efficiency of the turbine, but also, due to its sophisticated structure and precise matching of components, makes maintenance and adjustment of the entire system much easier. The meshing design of the adjustment worm 3 and the transmission worm gear 5 makes the blade adjustment process smoother and more precise, reducing mechanical wear caused by improper adjustment. The use of the locating bearing 4 ensures the stability of the transmission worm gear 5 at high speeds and extends its service life. In addition, the design of the adjustment mechanism 14 allows for fine-tuning of the blades to adapt to different water flow speeds and directions, thereby maintaining optimal performance of the turbine under different operating conditions.

[0027] With this structure, the turbine can respond more flexibly to changes in natural water flow. Whether it is a turbulent river or a gentle flow, it can capture the maximum energy by adjusting the angle of the blades, thereby improving the energy conversion efficiency of the entire power generation system.

[0028] The connection between the turbine shaft 8 and the turbine 15 is designed with a fixing block 9. The fixing block 9 is designed with an L-shaped structure. This structure is not only simple but also very strong, and can provide strong support force when the turbine is running. This design ensures that the connection between the turbine shaft 8 and the turbine 15 is firm, and can remain stable even under long-term operation and extreme water flow conditions, reducing equipment damage and efficiency loss caused by unstable connection. A first bolt 10 is designed inside the fixing block 9. This bolt passes through the fixing block 9 and tightly connects the turbine shaft 8 and the turbine 15 together. The design of the first bolt 10 takes into account the various forces that may be generated during the operation of the turbine, so it can ensure that the connection part will not loosen at any time, ensuring the continuous and stable operation of the turbine.

[0029] The other end of turbine shaft 8 is connected to generator shaft 1 via a third bolt 2. The design and material selection of third bolt 2 have been carefully considered to ensure it can transmit power while also withstanding the wear and stress of long-term operation. This connection method effectively converts the mechanical energy generated by the turbine into electrical energy, improving overall power generation efficiency.

[0030] In the design of the adjustment mechanism 14, the adjustment worm 2 is located below the transmission worm wheel 5. This layout design is very clever. It not only reduces the complexity of the entire structure, but also makes maintenance and adjustment easier. The design of the adjustment worm 2 allows it to be rotated manually or automatically, so that the angle of the blade can be adjusted as needed. This design provides high flexibility, allowing the turbine to quickly adapt to different water flow conditions. The rotation of the adjustment worm 2 is achieved through the transmission worm wheel 5, and the rotation of the transmission worm wheel 5 drives the adjustment worm 2 to move linearly, thereby achieving precise adjustment of the blades. This design not only improves the accuracy of the adjustment, but also improves the response speed of the entire system, allowing the turbine to quickly adjust the blades when the water flow conditions change to maintain the best working condition.

[0031] One end of the transmission worm gear 5 is connected to the adjustment rod 7 via a second bolt 6. This design cleverly utilizes the tightening effect of the second bolt 6 to ensure that the adjustment rod 7 can stably and finely move in response to the rotation of the transmission worm gear 5. This connection method simplifies the structure and improves the accuracy of fine-tuning. When the transmission worm gear 5 rotates, it transmits power to the adjustment rod 7 via the second bolt 6, thereby driving the movement of the entire blade adjustment mechanism.

[0032] One end of the adjustment rod 7 is further connected to the positioning structure 13. This connection ensures that the movement of the adjustment rod 7 is accurately transmitted to the positioning structure 13. An embedded positioning slot 16 is designed below the positioning structure 13. The design of this slot is crucial, preventing the positioning structure 13 from rotating. The positioning slot design ensures the positioning accuracy of the entire system, which is crucial for precise adjustment of the blades.

[0033] The connection between the adjustment rod 7 and the turbine 15 causes the turbine to slightly adjust its angle. The runner 12 is one of the core components of the turbine, and its movement is directly related to the angle and direction of the blades. Through the precise control of the adjustment rod 7, the runner 12 can be fine-tuned, thereby driving the blades 11 to make corresponding adjustments.

[0034] Attached to the outer side of the rotor body 12 are blades 11. The shape and material of blades 11 are chosen to adapt to varying water flow conditions. The design of blades 11 allows for dynamic adjustment based on the direction and speed of the water flow, maximizing the energy captured by the flow and optimizing the turbine's efficiency. Whether facing turbulent or gentle currents, blades 11 adapt to the changing flow by adjusting their angle and shape, maintaining efficient turbine operation.

[0035] The material of blades 11 is also selected to ensure excellent mechanical properties and durability despite long-term contact with water and the impact of currents. This material not only has sufficient strength and toughness, but also excellent corrosion resistance to adapt to the long-term operation of the turbine in various water quality environments. The shape design of blades 11 incorporates the principles of fluid mechanics to ensure maximum lift under the impact of water flow, driving the turbine's efficient operation.

[0036] The design of this blade adjustment structure not only improves the adaptability and power generation efficiency of the turbine, but also makes maintenance and adjustment of the entire system easier due to its sophisticated structure and precise matching of components. The meshing design of the adjustment worm 3 and the transmission worm wheel 5 makes the blade adjustment process smoother and more precise. The worm wheel itself also has a self-locking function, so only the worm can adjust the worm wheel, and the worm wheel cannot adjust the worm, reducing mechanical wear caused by improper adjustment. The use of a locating bearing 4 ensures the stability of the transmission worm wheel 5 during adjustment and extends its service life. The combination of the fixing block 9 and the first bolt 10 provides a stable connection between the turbine shaft 8 and the turbine 15, allowing the entire structure to remain stable even in the face of strong water flow impacts. The design of the second bolt 6 and the adjustment rod 7 makes the blade adjustment more flexible, can quickly respond to changes in water flow, and improve the operating efficiency of the turbine. At the same time, it improves the performance of the turbine and enhances its adaptability and reliability in different environments, with high practicality and cost-effectiveness.
