Abstract
Description
Technical Field
[0001] This utility model relates to the field of wind energy utilization technology, and in particular to the structure of a wind turbine for converting wind power into navigation power. Background Technology
[0002] A rotary sail is a wind energy utilization device based on the Magnus effect. It uses an electric motor to drive a cylindrical rotary drum to rotate at high speed. When crosswinds blow, the pressure difference between the two sides of the drum due to the difference in airflow speed creates a thrust perpendicular to the wind direction. The component of this thrust in the direction of the ship's movement can provide auxiliary power for the ship. Wind energy is a clean and renewable energy source.
[0003] In existing technologies, wind power conversion devices for navigation typically rely on wind turbines or cylindrical sails to capture wind energy, convert wind energy into mechanical energy through a drive shaft, and then output power through components such as hydraulic pumps. Currently, rotary sails are not used for power generation; their core function is to provide auxiliary propulsion for ships through the Magnus effect, thereby achieving energy conservation and emission reduction.
[0004] Existing structures have obvious problems with insufficient wind energy utilization. The design of traditional wind turbine blades or cylindrical sails focuses on the unidirectional conversion of wind energy into rotational mechanical energy, and only utilizes the tangential component of wind energy that drives the rotation of components. However, it does not make full use of the component of wind energy that can be converted into lift, resulting in some wind energy being directly lost because it is not effectively captured. Therefore, a wind turbine structure for converting wind energy into propulsion is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above deficiencies, this utility model provides a wind turbine structure for converting wind power into navigation energy, aiming to improve the problem of insufficient wind energy utilization in some existing devices.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A wind turbine structure for converting wind power into navigation includes a ship plate, a support assembly fixedly connected to the top of the ship plate, a spiral rotary sail rotatably connected to the top of the support assembly, a sail assembly fixedly connected to the outside of the spiral rotary sail, and a top cover fixedly connected to the top of the spiral rotary sail.

A drive shaft is fixedly connected inside the hydraulic pump. The drive shaft is rotatably connected to the inside of the propeller sail.
[0010] As a further description of the above technical solution:
[0011] The sail assembly includes multiple wind vanes, with adjacent sides of the multiple wind vanes fixedly connected to the outside of the propeller sail, and a propeller blade fixedly connected inside the wind vane, the propeller blade being fixedly connected inside to the outside of the propeller sail.
[0012] As a further description of the above technical solution:

[0020] This utility model has the following beneficial effects:
[0021] 1. In this utility model, wind energy is captured through the synergistic action of the wind vane and the spiral wind vane, which drives the spiral swivel sail to rotate. The torque is then transmitted to the hydraulic pump via the drive shaft, realizing the conversion of mechanical energy into hydraulic energy. The Magnus effect is adopted, and the spiral wind swivel is used to expand the wind energy conversion, which can improve the overall efficiency by more than 200%. The entire energy conversion process is continuous and has low loss, reducing the dependence on traditional fuels. The wind energy conversion rate exceeds 60%, which improves the energy utilization efficiency and environmental performance of ships.
[0022] 2. In this invention, the sliding block moves along the slide rail, causing the rotating rod to change angle, thereby enabling the oil film bearing to move up and down outside the spiral rotary sail. At low wind speeds, the height is reduced to increase the effective contact area; at high wind speeds, the height is increased to effectively support the spiral wind vane. This ensures optimal operation under different wind speed conditions, balancing wind energy utilization efficiency and structural stability, and improving the adaptability and reliability of the device.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] Reference Figure 1 , Figure 3 , Figure 4This utility model provides an embodiment of a wind turbine structure for converting wind power into navigation energy, including a hull plate 1 that transmits the entire weight of the device and the impact force generated during operation to the hull. A support assembly is fixedly connected to the top of the hull plate 1, and a spiral swivel sail 11 is rotatably connected to the top of the support assembly. A sail assembly is fixedly connected to the outside of the spiral swivel sail 11, and a top cover 14 is fixedly connected to the top of the spiral swivel sail 11. The support assembly includes a support chassis 10, the bottom of which is fixedly connected to the top of the hull plate 1. The support chassis 10 distributes the load of the superstructure and provides stable support. A hydraulic pump 5 is fixedly connected to the top of the support chassis 10, and a drive shaft 6 is fixedly connected inside the hydraulic pump 5. When the spiral swivel sail 11 rotates under the action of wind, it will generate wind power through friction. The drive shaft 6 is driven to rotate synchronously via a key connection, transmitting the rotational mechanical energy converted from wind energy to the hydraulic pump 5. The hydraulic pump 5 converts the mechanical energy transmitted by the drive shaft 6 into hydraulic energy. The external rotatable connection of the drive shaft 6 is connected to the inside of the spiral swivel sail 11. The sail assembly includes multiple wind vanes 12. When airflow passes through the wind vanes 12, a pressure difference is formed between the windward and leeward sides, generating a torque that pushes the wind vanes 12 to rotate. The adjacent sides of the multiple wind vanes 12 are fixedly connected to the outside of the spiral swivel sail 11. A spiral wind vane 13 is fixedly connected inside the wind vanes 12. The spiral wind vane 13 is fixedly connected inside the spiral swivel sail 11. When airflow flows along the spiral swivel sail 11, the spiral wind vane 13 can guide the airflow to generate a tangential component force, pushing the spiral swivel sail 11 to rotate.
[0031] Reference Figure 1 , Figure 2 A fixed base 2 is fixedly connected to the top of the boat plate 1. A sliding assembly is also fixedly connected to the top of the boat plate 1. An oil film bearing 7 is slidably connected to the outside of the spiral swivel sail 11. An adjusting assembly is rotatably connected to the bottom of the oil film bearing 7. The sliding assembly includes multiple slide rails 3. The fixed base 2 positions and fixes the slide rails 3. The bottom of the slide rails 3 is fixedly connected to the top of the boat plate 1. A slider 4 is slidably connected inside the slide rails 3. The slide rails 3 provide a sliding track for the slider 4, guiding the slider 4 to move in a specific direction. The adjusting assembly includes multiple rotating rods 8. The slider 4 can move along the slide rails 8. The rail 3 moves flexibly, adjusting the angle of the rotating rod 8 by changing its position. The top of the multiple rotating rods 8 is rotatably connected to the bottom of the oil film bearing 7. The oil film bearing 7 reduces the frictional resistance when the spiral drum sail 11 rotates, and at the same time provides support for the spiral drum sail 11. The bottom of the multiple rotating rods 8 is rotatably connected to the rotating shaft 9. The outside of the multiple rotating shafts 9 is rotatably connected to the inside of the multiple sliders 4. The far side of the multiple slide rails 3 is fixedly connected to the inside of the fixed base 2, and the near side of the multiple slide rails 3 is fixedly connected to the outside of the supporting chassis 10.
[0032] Working principle: Multiple wind vanes 12 generate rotational torque through the air pressure difference between the windward and leeward sides. The vertical axis spiral wind vane 13, with its special shape and structural design, allows a portion of the wind energy to be converted into upward lift during the rotation of the wind vanes, regardless of the forward wind resistance from ships or vehicles, wind from both sides, or wind from behind. The spiral wind vane 13 uses its spiral structure to guide the axial airflow to generate force, which drives the spiral rotary sail 11 to rotate around the drive shaft 6, completing the initial conversion of wind energy into mechanical energy. The rotation of the drive shaft 6 drives the hydraulic pump 5 to operate. The rotational torque generated by the wind turbine drives the hydraulic pump 5 to work. The hydraulic pump 5 converts mechanical energy into hydraulic energy, generating hydraulic flow. The hydraulic flow drives the hydraulic motor, which in turn drives the output shaft of the ship or vehicle, thereby providing assistance to the navigation equipment.
[0033] During operation, when wind speed and direction change, slider 4 slides along slide rail 3, driving rotating rod 8 to change angle via rotating shaft 9, thus pushing oil film bearing 7 to slide up and down on the outside of spiral sail 11. Oil film bearing 7 reduces frictional resistance to the rotation of spiral sail 11 through the oil film formed inside. Simultaneously, in conjunction with the angle adjustment of rotating rod 8, it adjusts the support position of spiral sail 11. When the wind speed is high, oil film bearing 7 is adjusted to a higher position on spiral sail 11 to prevent deformation due to excessive wind speed. When the wind speed is low, oil film bearing 7 is adjusted to a lower position on spiral sail 11 to increase the effective contact area between spiral sail 11 and natural wind.
[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
