Description

Technical Field

[0001] This invention relates to the field of marine auxiliary equipment technology, specifically to a rotary sail and a boat having the same. Background Technology

[0002] Spinner sails are installed on the deck of a ship and occupy less space compared to traditional sails. When the airflow direction is perpendicular to the length of the ship, the rotating spinner increases the fluid velocity on one side of the spinner and decreases the fluid velocity on the opposite side. The velocity difference between the two sides creates a pressure difference, which, using the Magnus effect, generates forward thrust on the spinner sail and thus acts on the hull, significantly reducing the energy consumption required for navigation.

When encountering light winds, each resistance fan can start rotating, thereby driving the lifting fan to rotate via the rotating shaft, thus starting the lifting fan and generating electricity through its rotation. As the speed of the lifting fan increases, when it exceeds the maximum limit speed of the resistance fan, each resistance mechanism retracts to form a second rotary section, reducing the rotational load. When the lifting fan speed is too high and there is a risk of stalling, each resistance mechanism deploys to form a resistance fan, increasing the load on the lifting fan and reducing its speed to maintain it at a normal level. This organic combination of resistance and lifting fans solves the problem of difficult lifting fan startup during power generation, ensures power generation efficiency, and also addresses the problem of stalling when the lifting fan speed is too high. Furthermore, in the vertical direction, multiple drag mechanisms and multiple lift mechanisms are alternately arranged in a reasonable layout, achieving a modular design and reducing design, manufacturing, and transmission difficulties during power generation. When forward thrust is required, the multiple lift and drag mechanisms retract, and the output shaft of the first drive motor is connected to the rotating shaft. The first drive motor can drive the rotating shaft, each first rotating section, and each second rotating section to rotate, utilizing the Magnus effect to generate forward thrust on the rotating sail, which in turn acts on the hull, significantly reducing the energy consumption required for navigation.

Detailed Implementation

[0050] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0051] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention.

[0052] In the description of this invention, it should be understood that the terms "top", "bottom", "inner", "outer", "axis", "circumferential", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention or simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0053] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0054] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," "fixing," "linking," "hinging," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0055] As mentioned in the background section, how to generate electricity using a rotary sail is a technical problem that urgently needs to be solved by those skilled in the art.

[0056] It should be noted that the existing rotary sail has an axial length of 20m ± 5m and a relatively high vertical height. The lifting fan works by utilizing the airflow velocity difference between the opposite sides of each blade to drive its rotation. The drag fan works by using one side of each blade as a choke point, and the impact of airflow on this choke point causes the drag fan to rotate. Lift fans are extremely difficult to start and almost impossible to start on their own. Drag fans are easy to start; however, their rotational speed is relatively slow, and their maximum speed limit is lower than that of lift fans, thus limiting their power generation efficiency.

[0057] To improve the above problems, refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A swivel sail is provided, comprising a shaft 110, multiple lift mechanisms 120, multiple drag mechanisms 130, a first drive motor, and a generator. The shaft 110 is vertically oriented. Multiple lift mechanisms 120 are evenly arranged around the shaft 110 along its axial direction. Each lift mechanism 120 can be deployed to form a lift fan with the shaft 110 or retracted to form a first swivel section. Multiple drag mechanisms 130 are evenly arranged around the shaft 110 along its axial direction. The drag mechanisms 130 and lift mechanisms 120 are alternately arranged vertically. Each drag mechanism 130 can be deployed to form a drag fan with the shaft 110 or retracted to form a second swivel section. The multiple second swivel sections and the multiple first swivel sections constitute the swivel of the swivel sail. The first drive motor is located below the shaft 110, and its output shaft can be connected to or disconnected from the bottom end of the shaft 110. The generator is also located below the rotating shaft 110, and its input shaft can be connected to or disconnected from the bottom end of the rotating shaft 110. When the multiple lift mechanisms 120 and multiple resistance mechanisms 130 are deployed, and the input shaft of the generator is connected to the rotating shaft 110, the airflow can drive each lift fan and each resistance fan to rotate in tandem, thereby generating electricity. When the multiple lift mechanisms 120 and multiple resistance mechanisms 130 are retracted, and the output shaft of the first drive motor is connected to the rotating shaft 110, the first drive motor can drive the rotating shaft 110, each first rotating section, and each second rotating section to rotate.

[0058] When power generation is needed, multiple lifting mechanisms 120 and multiple resistance mechanisms 130 deploy, and the generator's input shaft is connected to the rotating shaft 110. In the event of light winds, each resistance fan begins to rotate, which in turn drives the lifting fan via the rotating shaft 110, thus starting the lifting fan and generating electricity. As the lifting fan's speed increases, when it exceeds the maximum limit speed of the resistance fan, each resistance mechanism 130 retracts to form a second rotating section, reducing the rotational load. When the lifting fan's speed is too high and there is a risk of stalling, each resistance mechanism 130 deploys to form a resistance fan, increasing the load on the lifting fan and reducing its speed to maintain it at a normal level. This combination of resistance and lifting fans solves the problem of difficult lifting fan startup during power generation, ensures power generation efficiency, and addresses the issue of stalling when the lifting fan's speed is too high. Furthermore, in the vertical direction, multiple resistance mechanisms 130 and multiple lifting mechanisms 120 are alternately arranged, resulting in a reasonable layout and modular design. This reduces design difficulty, manufacturing difficulty, and transmission difficulty during power generation. The number of lifting mechanisms 120 and resistance mechanisms 130 that operate can be selected according to the power generation requirements.

[0059] When forward thrust is required, multiple lift mechanisms 120 and multiple drag mechanisms 130 retract, and the output shaft of the first drive motor is connected to the rotating shaft 110. The first drive motor can drive the rotating shaft 110, each first rotating section, and each second rotating section to rotate, utilizing the Magnus effect to generate forward thrust on the rotating sail, which in turn acts on the hull, greatly reducing the energy consumption required for navigation.

[0060] To enable the output shaft of the first drive motor to connect or disconnect from the bottom end of the rotating shaft 110, the output shaft of the first drive motor is connected to the rotating shaft 110 via a third clutch. To enable the input shaft of the generator to connect or disconnect from the bottom end of the rotating shaft 110, the rotary sail also includes a third transmission gear and a fourth transmission gear. The third transmission gear is sleeved on the bottom end of the rotating shaft 110. The inner wall of the fourth transmission gear is connected to the input shaft of the generator via a fourth clutch, and its side wall meshes with the side wall of the third transmission gear.

[0061] Specifically, in the exemplary example, each lifting mechanism 120 includes a lifting turntable 121, a lifting gear ring 122, multiple lifting gears 123, multiple racks 124, multiple lifting blades 125, a second drive motor, and a first transmission gear. The lifting turntable 121 is sleeved on the rotating shaft 110 and can rotate with or drive the rotating shaft 110 to rotate. The lifting gear ring 122 is arranged around the outer periphery of the lifting turntable 121, with upper meshing teeth on the upper part of the inner wall and lower meshing teeth on the lower part of the inner wall. The multiple lifting gears 123 are evenly distributed along the circumference of the lifting turntable 121. The middle part of each lifting gear 123 is rotatably connected to the top surface of the lifting turntable 121, and the sidewalls are meshed with the lifting gear ring 122 through upper meshing teeth. The multiple racks 124 are evenly distributed along the circumference of the lifting turntable 121. Each rack 124 has its axial direction parallel to the radial direction of the lifting turntable 121, its bottom slidably connected to the lifting turntable 121, and one side meshing with a plurality of lifting gears 123. A plurality of lifting blades 125 are evenly distributed circumferentially along the lifting turntable 121. One side of each lifting blade 125 is fixedly connected to one end of each rack 124. A second drive motor is mounted on the lifting turntable 121. The inner wall of the first transmission gear is fixedly connected to the output shaft of the second drive motor via a first clutch, and its side wall meshes with the lifting gear ring 122 via lower meshing teeth. When the first clutch is engaged, the second drive motor drives the lifting gear ring 122 to rotate via the first transmission gear, thereby driving each lifting gear 123 to rotate, causing each rack 124 to move radially along the lifting turntable 121, and thus causing the plurality of lifting blades 125 to move away from each other, achieving the purpose of deploying the lifting mechanism 120.

[0062] It should be noted that when power generation is required, the lift mechanism 120 unfolds to form a lift fan with the rotating shaft 110. The third clutch engages to connect the first drive motor to the rotating shaft 110, which loads the shaft to prevent rotation. With the first clutch engaged, the inner wall of the first transmission gear connects to the output shaft of the second drive motor, which drives multiple lift blades 125 to move away from each other. Then, the third clutch disengages to disconnect the first drive motor from the rotating shaft 110. During the rotation of the lift fan, the first clutch disengages to disconnect the inner wall of the first transmission gear from the output shaft of the second drive motor. The fourth clutch engages to connect the inner wall of the fourth transmission gear to the input shaft of the generator. Thus, the lift fan can drive the generator input shaft to rotate, enabling the generator to generate electricity. When forward thrust is required, the lift mechanism 120 closes to form the first rotating section. The third clutch engages to connect the first drive motor to the rotating shaft 110, which loads the shaft to prevent rotation. The first clutch engages, connecting the inner wall of the first transmission gear to the output shaft of the second drive motor. The second drive motor then drives multiple lifting blades 125 to move towards each other and close. Afterward, the first clutch disengages, disconnecting the inner wall of the first transmission gear from the output shaft of the second drive motor. The fourth clutch disengages, disconnecting the inner wall of the fourth transmission gear from the input shaft of the generator. Finally, the first drive motor drives the rotating shaft 110, the lifting turntable 121, and the first rotating drum section to rotate.

[0063] Preferably, a plurality of grooves 1211 are formed on the lifting turntable 121, and the grooves 1211 are evenly distributed along the circumference of the lifting turntable 121. The length direction of each groove 1211 is the same as the radial direction of the lifting turntable 121. A slider 1241 is provided at the bottom of the end of each rack 124 away from the corresponding lifting blade 125. The slider 1241 of each rack 124 is slidably disposed in a groove 1211. The slider 1241 cooperates with the groove 1211 to guide the movement of the lifting blade 125 and prevent over-expansion or over-retraction.

[0064] Preferably, each lifting blade 125 has an elliptical structure when projected downwards from top to bottom.

[0065] Preferably, each lifting mechanism 120 further includes multiple limiting electric push rods. These limiting electric push rods are mounted on the lifting turntable 121 and correspond one-to-one with multiple racks 124. One end of the output shaft of each limiting electric push rod abuts against a side of a rack 124 away from the corresponding lifting gear 123 to restrict the sliding of that rack 124. When forward thrust is required, after the second drive motor drives the multiple lifting blades 125 to move towards each other and close, one end of the output shaft of each limiting electric push rod abuts against a rack 124 to prevent the centrifugal force generated when the lifting turntable 121 rotates from causing the lifting mechanism 120 to self-open.

[0066] Specifically, in the exemplary example, each resistance mechanism 130 includes a resistance turntable 131, a resistance gear ring 132, multiple resistance gears 133, multiple resistance blades 134, a limiting turntable 135, a third drive motor, and a second transmission gear. The resistance turntable 131 is sleeved on the rotating shaft 110 and can rotate with or drive the rotating shaft 110 to rotate. The resistance gear ring 132 is arranged around the outer periphery of the resistance turntable 131, with upper meshing teeth on the upper part of the inner wall and lower meshing teeth on the lower part of the inner wall. The multiple resistance gears 133 are evenly distributed along the circumference of the resistance turntable 131. The middle part of each resistance gear 133 is rotatably connected to the top surface of the lifting turntable 121, and the sidewalls are meshed with the resistance gear ring 132 through upper meshing teeth. The multiple resistance blades 134 are evenly distributed along the circumference of the lifting turntable 121. The bottom center of multiple resistance blades 134 is fixedly connected to the center of the top surface of multiple resistance gears 133 one-to-one via a fixed shaft 1331. A limiting turntable 135 is also sleeved on the rotating shaft 110 and located above the resistance turntable 131, with multiple limiting blind grooves evenly distributed on its sidewall. One side of each resistance blade 134 is rotatably disposed within a limiting blind groove, and the other side is rotatably connected to the limiting turntable 135 via a rotating shaft 1351. The limiting blind grooves on the limiting turntable 135 prevent the resistance blades 134 from over-rotating. A third drive motor is mounted on the resistance turntable 131. The inner wall of the second transmission gear is fixedly connected to the output shaft of the third drive motor via a second clutch, and its sidewall is meshed with the resistance gear ring 132 via lower meshing teeth. When the second clutch is engaged, the third drive motor drives the resistance gear ring 132 to rotate via the second transmission gear, thereby driving each resistance gear 133 to rotate, thus causing each resistance blade 134 to rotate, achieving the purpose of deploying the resistance mechanism 130.

[0067] It should be noted that when power generation is required, the resistance mechanism 130 unfolds to form a resistance fan with the rotating shaft 110. The third clutch engages to connect the first drive motor to the rotating shaft 110, and the first drive motor generates a load on the rotating shaft 110 to prevent it from rotating. The second clutch engages, and the inner wall of the second transmission gear connects to the output shaft of the third drive motor, which drives the resistance gear ring 132 to rotate, thereby causing multiple resistance gears 133 and multiple resistance blades 134 to rotate. Afterwards, the third clutch disengages to disconnect the first drive motor from the rotating shaft 110. During the rotation of the resistance fan, the second clutch disengages to disconnect the inner wall of the second transmission gear from the output shaft of the third drive motor. The fourth clutch engages to connect the inner wall of the fourth transmission gear to the input shaft of the generator. In this way, the resistance fan can drive the rotating shaft 110, the lift mechanism 120, and the generator input shaft to rotate, enabling the generator to generate electricity. When forward thrust is required, the resistance mechanism 130 closes to form the second rotating section, and the third clutch engages to connect the first drive motor to the rotating shaft 110. The first drive motor applies a load to the rotating shaft 110 to prevent it from rotating. The second clutch engages, connecting the inner wall of the second transmission gear to the output shaft of the third drive motor, which then drives the multiple resistance blades 134 to rotate and reset. Afterward, the second clutch disengages, disconnecting the inner wall of the second transmission gear from the output shaft of the third drive motor. The fourth clutch disengages, disconnecting the inner wall of the fourth transmission gear from the input shaft of the generator. Finally, the first drive motor drives the rotating shaft 110, the resistance disc 131, and the second rotating section to rotate.

[0068] Preferably, each resistance gear 133 is a half gear.

[0069] Preferably, the first clutch of each lifting mechanism 120, the second clutch, the third clutch and the fourth clutch of each resistance mechanism 130 are all electric clutches.

[0070] To facilitate power supply by wiring, multiple conductive slip rings are provided on the rotating shaft 110.

[0071] Specifically, in the exemplary example, the rotary sail also includes a bottom tube. The bottom tube is covered outside the first drive motor and generator, and a lifting mechanism 120 and a drag mechanism 130 are mounted on top, providing support for the lifting mechanism 120 and the drag mechanism 130.

[0072] Preferably, there are two lifting mechanisms 120 and two drag mechanisms 130. The rotary sail also includes four first support rods and four second support rods. The four first support rods are located on a common side of the rotating shaft 110 and are evenly distributed in the vertical direction. One end of each first support rod is fixedly connected to the rotating shaft 110, and the other end is provided with a rotatable first ball bearing. The four second support rods are located on the other common side of the rotating shaft 110 and are evenly distributed in the vertical direction. One end of each second support rod is fixedly connected to the rotating shaft 110, and the other end is provided with a rotatable second ball bearing. The bottom end of the lifting gear ring 122 of each lifting mechanism 120 is provided with a ball groove 1221 along the circumferential direction that is adapted to the first and second balls bearings. Each lifting gear ring 122 of the lifting mechanism 120 is supported by the rotating shaft 110, one first support rod, one first ball bearing, one second support rod, and one second ball bearing. The bottom end of the resistance gear ring 132 of each resistance mechanism 130 is also provided with a ball groove 1221 adapted to the first ball and the second ball along the circumferential direction. The resistance gear ring 132 of each resistance mechanism 130 is supported by a rotating shaft 110, a first support rod, a first ball, a second support rod and a second ball.

[0073] Preferably, the spinner also includes a top cover, the middle of the bottom end of which is fixedly connected to the top end of the spinner 110, and can rotate with the spinner 110. The top cover can prevent rainwater from falling into the spinner, effectively extending the service life of the spinner.

[0074] The present invention also provides a boat with a spinner sail, comprising a hull and the spinner sail provided in any of the above specific embodiments. The spinner sail is mounted on the deck of the hull.

[0075] When power generation is needed, multiple lifting mechanisms 120 and multiple resistance mechanisms 130 deploy, and the generator's input shaft is connected to the rotating shaft 110. In the event of light winds, each resistance fan begins to rotate, which in turn drives the lifting fan via the rotating shaft 110, thus starting the lifting fan and generating electricity. As the lifting fan's speed increases, when it exceeds the maximum limit speed of the resistance fan, each resistance mechanism 130 retracts to form a second rotating section, reducing the rotational load. When the lifting fan's speed is too high and there is a risk of stalling, each resistance mechanism 130 deploys to form a resistance fan, increasing the load on the lifting fan and reducing its speed to maintain it at a normal level. This combination of resistance and lifting fans solves the problem of difficult lifting fan startup during power generation, ensures power generation efficiency, and addresses the issue of stalling when the lifting fan's speed is too high. Furthermore, in the vertical direction, multiple resistance mechanisms 130 and multiple lifting mechanisms 120 are alternately arranged, resulting in a reasonable layout and modular design. This reduces design difficulty, manufacturing difficulty, and transmission difficulty during power generation. The number of lifting mechanisms 120 and resistance mechanisms 130 that operate can be selected according to the power generation requirements.

[0076] When forward thrust is required, multiple lift mechanisms 120 and multiple drag mechanisms 130 retract, and the output shaft of the first drive motor is connected to the rotating shaft 110. The first drive motor can drive the rotating shaft 110, each first rotating section, and each second rotating section to rotate, utilizing the Magnus effect to generate forward thrust on the rotating sail, which in turn acts on the hull, greatly reducing the energy consumption required for navigation.
