[0002] Among the existing wind-assisted navigation technologies for ships, there are mainly two types of devices used to utilize wind energy to assist ship navigation. The first is the wing-shaped sail, which generates lift by adjusting the wind angle between the sail surface and the wind direction, thereby propelling the ship forward. The second is the rotor sail, also known as the rotor sail or Magnus effect sail, which uses the Magnus effect to generate a pressure difference on the surface of a rotating cylinder to obtain thrust. These technologies can reduce the fuel consumption and environmental pollution of ships to a certain extent, especially when the wind conditions are suitable, they can significantly improve navigation efficiency.

[0025] The present invention will be further described below with specific embodiments:

[0026] This embodiment provides a wind-powered navigation aid device for a ship, which is arranged on the deck of a large cargo ship and is used to utilize natural wind power to propel the ship forward.

[0027] See also Figure 1 , Figure 2 and Figure 3 ,

[0028] Specifically, the main body of the wind power navigation aid device of this embodiment is a huge deformable cylinder 1. In addition, the deformable cylinder 1 is also provided with a base 2 and a rotating drum motor.

[0029] The deformable cylinder 1 includes a rotating drum frame 11 and four wing sail panels 13 .

[0030] The drum frame 11 is in an upright state as a whole, and is composed of an upper end plate 111, a lower end plate 112 and an upright drum shaft 113. The upper end plate 111 is fixedly arranged at the upper end of the drum shaft 113, and the lower end plate 112 is fixedly arranged at the middle section of the drum shaft 113, thereby forming a complete structure of the drum frame 11.

[0031] In order to install the entire deformable cylinder 1 on the ship, a base 2 is arranged on the deck of the ship, and a bearing is provided in the base 2. The drum shaft 113 of the drum frame 11 is installed on the base 2 through the bearing, that is, it is installed based on the base 2. In this way, the drum frame 11 can rotate based on the base 2, or in other words, the entire deformable cylinder 1 can rotate based on the base 2.

[0032] In addition, for the deformable cylinder 1, a drum motor is specially configured in the ship hull, and the drum shaft 113 of the drum frame 11 is assembled and connected to the drum motor. The drum motor can drive the drum frame 11 to rotate by driving the drum shaft 113, or in other words, it can drive the entire deformable cylinder 1 to rotate.

[0033] The upper end plate 111 and the lower end plate 112 are two circular plates of the same configuration, the upper end plate 111 and the lower end plate 112 are parallel to each other, and both are perpendicular to the drum shaft 113, and the central axes of the upper end plate 111, the lower end plate 112 and the drum shaft 113 are coaxial. There is a large space between the upper end plate 111 and the lower end plate 112, and the space can be used to accommodate and install four wing sail panels 13.

[0034] For the convenience of description, the space between the upper end plate 111 and the lower end plate 112 is referred to as a peripheral installation space.

[0035] The configurations of the four wing panels 13 described above are consistent. The wing panel 13 is an elongated airfoil as a whole, that is, similar to an airplane wing, with one side being an arc surface and the other side being a plane. The four wing panels 13 are gathered together, and their arc surfaces are seamlessly spliced ​​together to form a cylindrical configuration. The cylindrical configuration can be used to realize the Magnus effect (described in detail later).

[0036] The four wing sail panels 13 are all installed based on the drum frame 11 , specifically, they are installed in the peripheral installation space of the drum frame 11 and are in an upright state. Moreover, the four wing sail panels 13 are evenly and discretely arranged along the circumference of the drum frame 11 .

[0037] Most importantly, all four wing sail panels 13 are assembled on the drum frame 11 through a specially designed orientation change mechanism (the specific structure will be described later). The wing sail panels 13 can change the rotation angle and movement position on the drum frame 11 based on the orientation change mechanism. In other words, the deformable drum body 1 composed of the drum frame 11 and the four wing sail panels 13 can change its configuration.

[0038] More specifically, the deformable cylinder 1 can be transformed into two configurations:

[0039] Gathered cylindrical configuration,

[0040] The four wing sail panels 13 are moved and changed in position based on the position changing mechanism, and the four wing sail panels 13 are gathered together, and the arc surfaces of the four wing sail panels 13 are seamlessly spliced ​​together to form a cylindrical configuration (such as Figure 3 As shown), the axis of the cylindrical configuration is coaxial with the drum axis 113; the convergent cylindrical configuration is used to achieve the Magnus effect.

[0041] Spread sail configuration,

[0042] The four wing sail panels 13 are moved and changed in position based on the position changing mechanism, and the four wing sail panels 13 are dispersed (such as Figure 1 As shown), the plane of the wing sail board 13 can then be controlled to face the incoming wind direction as the windward surface.

[0043] The deformable cylinder 1 can be converted back and forth between a gathered cylinder configuration and a spread sail configuration.

[0044] The aforementioned “all four sail panels 13 are assembled on the drum frame 11 through a specially designed orientation change mechanism” is specifically implemented in the following structural form:

[0045] A sail-turning shaft 131 is provided for each wing sail board 13, and the sail-turning shaft 131 is penetrated in the wing sail board 13 and is penetrated along the length direction of the wing sail board 13. Both ends of the sail-turning shaft 131 protrude from the end portion of the wing sail board 13, thereby forming pivot ends at both ends of the wing sail board 13. For each wing sail board 13 penetrated by the sail-turning shaft 131, a slide groove 132 is provided on the upper end plate 111 and the lower end plate 112. Both ends of the sail-turning shaft 131, that is, the pivot ends at both ends of the wing sail board 13, are respectively assembled in the slide grooves 132 opened on the upper end plate 111 and the lower end plate 112. The sail-turning shaft 131 is assembled with the slide grooves 132 opened on the upper end plate 111 and the lower end plate 112 to form an azimuth changing mechanism.

[0046] The wing sail board 13 is based on the sail shaft 131. On the one hand, it can rotate at an angle, that is, change direction. On the other hand, it can also move along the slide groove 132, that is, change position, thereby achieving the effect of "position change".

[0047] It should be noted that the extended line of the axis of the chute 132 on which each wing sail board 13 is based passes through the drum shaft 113 of the drum frame 11, and all the chute 132 are arranged radially with the drum shaft 113 as the center, so that when the wing sail board 13 moves along the chute 132, it can approach or move away from the drum shaft 113, that is, approach or move away from the middle of the drum frame 11. When all the wing sail boards 13 are close to the middle of the drum frame 11, all the wing sail boards 13 are gathered and combined in the middle of the drum frame 11, so as to form a gathered cylinder configuration; when all the wing sail boards 13 are far away from the middle of the drum frame 11, all the wing sail boards 13 are dispersed, so as to form a dispersed sail configuration.

[0048] In other embodiments, it is not necessary to provide the sail shaft 131 in the wing sail board 13 , as long as pivot ends that can be matched and assembled with the slide slot 132 can be provided at both ends of the wing sail board 13 .

[0049] In addition, it is also necessary to configure a wing sail driving mechanism for the wing sail board 13 to drive the wing sail board 13 to perform transformation actions based on the azimuth transformation mechanism. On the one hand, it is necessary to realize the position gathering and dispersion of the driven wing sail board 13, and on the other hand, it is necessary to realize the rotation angle of the driven wing sail board 13.

[0050] Specifically,

[0051] In this embodiment, the wing sail driving mechanism includes a hydraulic telescopic cylinder and a sail turning motor, wherein the hydraulic telescopic cylinder is used to drive the wing sail board 13 to perform a "displacement action" based on the azimuth transformation mechanism, and the sail turning motor is used to drive the wing sail board 13 to perform a "rotation angle action" based on the azimuth transformation mechanism. In this way, by driving the "displacement" and "angle transformation" of the wing sail board 13, the deformable cylinder 1 can achieve the transformation effects of the "gathering cylinder configuration" and the "dispersing sail configuration" mentioned above.

[0052] It should be noted that it is easy for those skilled in the art to design a specific structure of the wing sail driving mechanism for the wing sail board 13 and the azimuth changing mechanism, and there are a large number of ready-made wing sail driving mechanisms in the prior art to drive the azimuth changing mechanism. In other embodiments, the wing sail driving mechanism can be set according to specific needs, and the present invention is not limited to this.

[0053] The drum frame 11 and the wing sail board 13 are both made of high-strength, corrosion-resistant materials, which can ensure the long service life of the wind-powered navigation aid device under adverse weather conditions, and is also conducive to simplifying the azimuth change mechanism, which can reduce costs and maintenance difficulties.

[0054] The working principle of the wind power navigation aid device of this embodiment is as follows:

[0055] During the navigation of the ship, the deformable cylinder 1 is controlled to change its configuration according to the wind direction.

[0056] When the wind direction is side wind, the deformable cylinder 1 is controlled to transform into a gathered cylindrical configuration, and all the wing sail panels 13 are gathered together to form a seamless cylindrical configuration. The deformable cylinder 1 is driven to rotate by a rotating drum motor. Based on the Magnus effect, the wind force can be used to indirectly propel the ship forward.

[0057] When the wind direction changes or greater thrust is needed, the deformable cylinder 1 is controlled to transform into a dispersed sail configuration, all the wing sail panels 13 are dispersed, and then the plane of the wing sail panels 13 is controlled as the windward side facing or oblique to the wind direction. The entire deformable cylinder 1 is like a sail and can directly use wind power to propel the ship forward.

[0058] In addition, in order to realize intelligent automatic control, an automatic control system may be provided for the wing sail driving mechanism on the ship, and the automatic control system is used to automatically control the wing sail driving mechanism.

[0059] An artificial intelligence decision-making module is also provided in the automatic control system to realize intelligent control of the "configuration transformation of the deformable cylinder 1".

[0060] Wind measuring instruments and other environmental detection instruments are provided at appropriate locations on the ship. The wind measuring instruments can detect and obtain various wind-related data, such as wind speed, wind direction, wind force, etc. The environmental detection instruments can detect and obtain atmospheric environment data, such as temperature, air pressure, and air humidity.

[0061] If wind measuring instruments and environmental detection instruments are collectively referred to as meteorological detection instruments, they can be summarized as follows:

[0062] Meteorological detection instruments are installed at appropriate locations on the ship to detect and obtain meteorological data, such as wind speed, wind direction, wind force, temperature, air pressure, air humidity, etc.

[0063] The above-mentioned meteorological detection instrument is connected to the data signal of the automatic control system. The meteorological detection instrument can transmit the meteorological data detected and acquired to the automatic control system. The automatic control system automatically controls the configuration change of the deformable cylinder 1 according to the meteorological data and a pre-set control algorithm, so that the entire wind-powered navigation aid device can achieve optimal performance under different wind conditions.

[0064] See also Figure 4 and Figure 5 The wind power navigation aid device of this embodiment is arranged on the deck of the ship. When the wind direction is side wind, the deformable cylinder 1 is transformed into a gathered cylinder configuration. Based on the Magnus effect, the wind power can be used to indirectly propel the ship forward. Figure 4 When the wind direction changes or a greater thrust is needed, the deformable cylinder 1 is transformed into a dispersed sail configuration. The entire deformable cylinder 1 acts like a sail and can directly use the wind to propel the ship forward. Figure 5 shown.

[0065] The process of the automatic control system controlling the operation of the wind power navigation aid device is as follows:

[0066] 1) System initialization: Start the automatic control system and perform self-check to ensure that all meteorological detection instruments and wingsail drive mechanisms are operating normally.

[0067] 2) Wind direction and speed monitoring: The automatic control system monitors the current wind environment in real time through wind measuring instruments.

[0068] 3) Mode selection:

[0069] If it is detected that the wind direction is side wind and the wind force is appropriate, the automatic control system sends a command to the wing sail driving mechanism to gather all the wing sail panels 13 to form a cylindrical configuration, and the entire deformable cylinder 1 is transformed into a gathered cylindrical configuration to form a Magnus wind cylinder effect.

[0070] If the wind direction changes or greater thrust is needed, the automatic control system sends instructions to the wing sail drive mechanism, so that the entire deformable cylinder 1 is transformed into a dispersed sail configuration, all the wing sail panels 13 are dispersed, and the plane of the wing sail panels 13 is controlled as the windward side facing or oblique to the direction of the wind, and the entire deformable cylinder 1 acts as a sail.

[0071] 4) Angle adjustment of the wing sail board 13:

[0072] After the wing sail panels 13 are dispersed, the automatic control system controls the wing sail driving mechanism to adjust the direction angle of the wing sail panels 13 according to the change of the wind environment to obtain the best angle of attack.

[0073] 5) Rotation control of the deformable cylinder 1:

[0074] In the Magnus effect mode, the automatic control system controls the drum motor to control the rotation of the deformable drum 1, and uses the airflow changes generated by the rotation to propel the ship.

[0075] 6) Safety monitoring:

[0076] During the entire operation process, the automatic control system continuously monitors the dynamics and wind conditions of the ship, and automatically adjusts the angle of the wing sail board 13 or retracts the wing sail board 13 when necessary to ensure the safety of the ship.

[0077] 7) System shutdown:

[0078] When wind power is not needed to assist navigation or adverse weather conditions occur, the automatic control system sends a command to the wing sail driving mechanism to retract the wing sail board 13, so that the wind power navigation aid device enters a standby state.

[0079] Through the above structure and operation steps, the wind-powered navigation aid device of the present invention, wherein the deformable cylinder 1 can flexibly change its configuration according to actual wind conditions, not only utilizing the Magnus effect but also being used as a sail, thereby improving the navigation efficiency and adaptability of the ship.

[0080] It should be noted that, in this embodiment, four wing sail panels 13 are provided on the deformable cylinder 1. However, in other embodiments, the specific number of wing sail panels 13 used can be determined according to actual conditions, and the present invention has no limitation on this.

[0081] It should be noted that the wind-powered navigation aid device of the present invention is not limited to being used in large cargo ships, but can also be used in other types of ships as long as there is a demand.

[0082] The wind power navigation aid device of this embodiment has the following advantages:

[0083] 1) Functional diversity: A deformable cylinder 1 is provided in the wind-powered navigation aid device. The deformable cylinder 1 can be transformed into a gathered cylinder configuration or a dispersed sail configuration.

[0084] When transformed into a converged cylinder configuration, it can indirectly use wind power to propel the ship forward based on the Magnus effect;

[0085] When it is transformed into a dispersed sail configuration, it can directly use the wind to propel the ship forward just like a sail;

[0086] This achieves a dual-function effect, making the most of natural wind power to propel the ship forward, thereby improving the utilization rate of green energy and greatly saving fuel consumption.

[0087] 2) Improve efficiency: Optimize structural design, improve the utilization efficiency of wind energy, and enable the equipment to operate effectively under different wind conditions.

[0088] 3) Reduce complexity: Through integrated design, simplify the structure, reduce costs, and improve the intelligence of the control system.

[0089] The above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
