[0002] Modern ocean-going vessels typically need to sail at sea for extended periods, making it difficult to frequently return to port for resupply. However, the energy storage capacity of shipboard batteries is limited, making it difficult to continuously meet the power demands during voyages. Therefore, utilizing renewable energy sources (such as wind power) to provide auxiliary power to ships is of great significance.

[0003] The marine environment is complex and changeable, often encountering extreme weather such as strong winds and heavy rain. Traditional wind power generation devices usually adopt a fixed tower structure, which cannot be stored in harsh weather conditions, which can easily lead to damage to the wind turbine, affecting power generation efficiency and equipment life.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing description of the drawings are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings are used to distinguish different objects, not to describe a particular order; the terms "inner," "outer," "left," and "right" indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the invention and 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, and therefore should not be construed as a limitation of the invention.

[0033] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0034] This invention provides a combined wind power generation device, such as... Figure 1-13 As shown, the combined wind power generation device includes: a base 1 and a connecting block 2 rotatably mounted on the base 1; a tower 3 fixedly mounted on the top of the connecting block 2; a generator 4 for wind power generation mounted on the top of the tower 3 and wind blades 5 mounted on the generator 4; several collection nets 6 respectively located on both sides of the tower 3 for collecting sea fog; water collection troughs 7 respectively installed at the bottom of the several collection nets 6 for centralized drainage; a servo motor 8 fixedly mounted on one side of the base 1 for driving the tower 3 to rotate and storing the wind blades 5, the output shaft of the servo motor 8 being fixedly connected to the rotating shaft of the connecting block 2; and a reinforcement mechanism located on one side of the base 1 for reinforcing the tower 3.

[0035] In this embodiment, during normal wind power generation, the natural wind at sea acts on the wind turbine blade 5. When the wind blows across the blade 5, a pressure difference is generated on its surface. This pressure difference creates a torque that causes the blade 5 to rotate, thus driving it to begin rotating. The rotational motion of the blade 5 is transmitted to the rotor of the generator 4, causing the rotor to rotate within the stator of the generator 4. According to the principle of electromagnetic induction, when a conductor in a closed circuit moves in a magnetic field, cutting magnetic field lines, an induced electromotive force is generated in the conductor, which in turn generates an induced current. In the generator 4, the rotation of the rotor is equivalent to the conductor in a closed circuit moving in a magnetic field, cutting magnetic field lines. Therefore, an induced current is generated inside the generator 4, realizing the process of converting wind energy into electrical energy and providing auxiliary power to the ship.

[0036] Meanwhile, several collection nets 6 on both sides of the tower 3 are in an unfolded state, which can capture sea fog. When the fog flows through the mesh structure of the collection net 6, the water droplets collide with and adhere to the net wires. After the water droplets merge and increase in size, they flow along the net wires to the water collection tank 7 below due to gravity, and are then discharged through the drain pipe on the water collection tank 7.

[0037] When encountering extreme weather such as strong winds and heavy rain, the servo motor 8 drives the tower 3 to rotate, changing the tower 3 from a vertical to a horizontal position, thus storing the wind turbine blades 5 and the tower 3 to prevent equipment damage. By driving the tower 3 to rotate, the wind turbine blades 5 are tilted and stored, effectively protecting the generator 4 and the wind turbine blades 5, thereby extending the service life of the equipment and ensuring power generation efficiency. By setting several collection nets 6 and water collection tanks 7 on both sides of the tower 3, sea fog can be collected while generating wind power, and the seawater condensed from the sea fog can be collected, realizing the diversification of functions and improving the utilization rate of the device.

[0038] In a further preferred embodiment of the present invention, a support plate 9 is fixedly installed on one side of the tower 3, and two bidirectional screws 10 are rotatably installed on the bottom of the support plate 9. A plurality of threaded cylinders 11 are threaded on the bidirectional screws 10, and two telescopic plates 12 for folding and storing a plurality of collection nets 6 are respectively installed on the plurality of threaded cylinders 11. The two telescopic plates 12 are respectively fixedly connected to the plurality of collection nets 6.

[0039] In this embodiment, as the tower 3 rotates from a horizontal to a vertical position, the collection net 6 unfolds simultaneously. At this time, the bidirectional screw 10 is driven to rotate by the linkage mechanism. Since it is threadedly engaged with several threaded cylinders 11, the rotation of the bidirectional screw 10 releases the threaded cylinders 11, causing them to move along the bidirectional screw 10. Two telescopic plates 12 are respectively installed on the threaded cylinders 11, and the two telescopic plates 12 are respectively connected to several collection nets 6. As the threaded cylinders 11 move, the two telescopic plates 12 are extended and retracted, thereby pulling the two collection nets 6 at the bottom of the two telescopic plates 12 to slide away from each other. The collection nets 6, which were originally in a cross-folded state, slide outward to better collect sea fog. While the wind blade 5 is being stored, the linkage mechanism simultaneously drives the bidirectional screw 10 to rotate in the opposite direction, causing the threaded cylinders 11 to move in the opposite direction, driving the telescopic plates 12 to retract, so that the collection nets 6 are folded and stored again. Through the cooperation of the bidirectional screw 10, the threaded cylinders 11, and the telescopic plates 12, the unfolding and storage of the collection nets 6 can be precisely and quickly controlled.

[0040] In a further preferred embodiment of the present invention, the reinforcement mechanism includes: a U-shaped frame 13 disposed on one side of the base 1, the U-shaped frame 13 enclosing the tower rod 3; an insert rod 14 inserted into one side of the tower rod 3, the insert rod 14 passing through one side of the U-shaped frame 13; a fixing block 15 fixedly installed on one side of the U-shaped frame 13; a threaded rod 16 inserted into the fixing block 15 for fixing the insert rod 14 to the U-shaped frame 13, the threaded rod 16 passing through the insert rod 14; and a nut installed at the bottom of the fixing block 15 for cooperating with the threaded rod 16 and fixing the tower rod 3, the nut being threadedly connected to the threaded rod 16.

[0041] In this embodiment, when the tower 3 is in a vertical state, the U-shaped frame 13 encloses the tower 3. Then, the insert rod 14 is inserted into the tower 3, ensuring that the insert rod 14 passes through one side of the U-shaped frame 13. This initially restricts the partial displacement of the tower 3 relative to the U-shaped frame 13. Next, the lead screw 16 is inserted into the fixing block 15 fixedly installed on one side of the U-shaped frame 13, ensuring that the lead screw 16 passes through the insert rod 14. Finally, the lead screw 16 is threadedly connected to the nut. By rotating the lead screw 16, the threaded engagement between the lead screw 16 and the nut allows the lead screw 16 to move along the nut and gradually tighten, thereby firmly fixing the insert rod 14 to the U-shaped frame 13. This ultimately achieves a stable fixation of the tower 3. By enclosing the tower 3 with the U-shaped frame 13 and utilizing the cooperation of the insert rod 14, lead screw 16, and nut, the tower 3 is constrained and fixed from multiple directions, effectively reducing the horizontal sway of the tower 3 and greatly enhancing its stability.

[0042] In a further preferred embodiment of the present invention, the insertion rod 14 is rectangular, and one side of the connecting block 2 is in close contact with the inner wall of the base 1.

[0043] In this embodiment, the insertion rod 14 is rectangular, which increases the contact area and friction between the insertion rod 14 and the tower rod 3 and the U-shaped frame 13. After the insertion rod 14 is fixed by the lead screw 16 and the nut, the rectangular insertion rod 14 can more effectively prevent the tower rod 3 from rotating or translating relative to the U-shaped frame 13.

[0044] In a further preferred embodiment of the present invention, an auxiliary support mechanism for assisting in the lowering of the tower rod 3 is provided on one side of the base 1. The auxiliary support mechanism includes: a fixed box 17 disposed on one side of the base 1; a rotating drum 18 rotatably installed in the fixed box 17 for winding the wire rope 20; a guide frame 19 disposed on the right side of the fixed box 17 for guiding the wire rope 20, the wire rope 20 passing around the guide frame 19 and fixedly connected to the tower rod 3; and a transmission mechanism disposed on the rotating shaft of the connecting block 2 and the rotating drum 18 for synchronously driving the connecting block 2 and the rotating drum 18 to rotate.

[0045] In this embodiment, when the vertical tower 3 needs to be laid down to a horizontal position, the servo motor 8 drives the connecting block 2 to rotate, thereby causing the tower 3 to start rotating and falling down. At the same time, since the connecting block 2 and the rotating cylinder 18 are equipped with a transmission mechanism, the transmission mechanism operates synchronously during the rotation of the connecting block 2, transmitting the rotation of the connecting block 2 to the rotating cylinder 18, driving the rotating cylinder 18 to rotate inside the fixed box 17. The steel wire rope 20 wound on the rotating cylinder 18 is released as the rotating cylinder 18 rotates. The steel wire rope 20 passes around the wire frame 19 on the right side of the fixed box 17 and is fixedly connected to the tower 3. During the process of lowering the tower 3, the steel wire rope 20 plays an auxiliary support and guiding role for the tower 3, enabling the tower 3 to be laid down smoothly and improving the stability when it is laid down and stored. The auxiliary support of the steel wire rope 20 can prevent the tower 3 from accidentally tipping over or losing control, effectively improving the safety of the entire operation process.

[0046] In a further preferred embodiment of the present invention, the transmission mechanism includes: a first differential gear 21 respectively disposed on the shaft of the fixed box 17 and the rotating drum 18, the two first differential gears 21 meshing with each other; a differential drive wheel 22 respectively fixedly sleeved on the shaft of the connecting block 2 and the shaft of the first differential gear 21 located on one side of the fixed box 17, and a belt 23 sleeved on the two differential drive wheels 22.

[0047] In this embodiment, when the vertical tower 3 needs to be lowered, the servo motor 8 drives the connecting block 2 to start rotating. When the connecting block 2 rotates, it drives the differential drive wheel 22 on it to rotate, which in turn drives the differential drive wheel 22 on one side of the fixed box 17 to rotate through the belt 23. The differential drive wheel 22 drives the first differential gear 21 connected to it to rotate. The first differential gear 21 on the rotating shaft of the rotating drum 18 inside the fixed box 17 meshes with the aforementioned rotating first differential gear 21. According to the transmission principle of differential gears, the two meshing differential gears will generate a speed difference during transmission. By reasonably designing the specifications of the two first differential gears 21, the rotation speed of the rotating drum 18 can be made much higher than the rotation speed of the connecting block 2. As the rotating drum 18 rotates rapidly, the steel wire rope 20 wrapped on the rotating drum 18 is quickly released, thereby meeting the requirement for the length of the steel wire rope 20 during the lowering of the tower 3.

[0048] In a further preferred embodiment of the present invention, two limiting wheels 57 for guiding the wire rope 20 are fixedly installed on the support plate 9.

[0049] In this embodiment, when the auxiliary support mechanism is running, the wire rope 20 is released from the rotating drum 18 inside the fixed box 17. During the entire movement of the wire rope 20, the wire rope 20 will contact the wheel surfaces of the two limit wheels 57 as it travels. The limit wheels 57 guide the wire rope 20 to move along a predetermined path by rotating on their own, ensuring that the wire rope 20 always stays in the correct position during release and stress.

[0050] In a further preferred embodiment of the present invention, a protective cover 24 is fixedly installed on one side of the support plate 9. The protective cover 24 and the two bidirectional screws 10 are each provided with a first sprocket 25. A first chain 26 for synchronously driving the two bidirectional screws 10 to rotate is sleeved on the plurality of first sprockets 25. The first chain 26 meshes with the plurality of first sprockets 25. The first sprockets 25 and the protective cover 24 are provided with a linkage mechanism for synchronously driving the connecting block 2 and the bidirectional screws 10 to rotate.

[0051] In this embodiment, while the servo motor 8 drives the connecting block 2 to rotate, thereby knocking down the tower 3, the linkage mechanism enables multiple first sprockets 25 to rotate synchronously, thereby driving the bidirectional screw 10 to rotate. This allows several collection nets 6 to slide and fold in a relatively cross manner while the tower 3 is knocked down, and to slide and unfold in a relatively cross manner while the tower 3 is erected.

[0052] In a further preferred embodiment of the present invention, the linkage mechanism includes: a rotating rod 27 rotatably mounted on the protective cover 24; second sprockets 28 respectively fixedly sleeved on the rotating rod 27 and the shaft of the first sprocket 25, with second chains 29 sleeved on the two second sprockets 28, the second chains 29 meshing with the two second sprockets 28; a fixing plate 30 fixedly mounted on the top of the connecting block 2; second differential gears 31 respectively disposed on the fixing plate 30 and the shaft of the connecting block 2, the two second differential gears 31 meshing with each other; third differential gears 32 respectively disposed on the fixing plate 30 and the shaft of the second differential gears 31 located on the fixing plate 30, the two third differential gears 32 meshing with each other; two differential sprockets 33 respectively fixedly sleeved on the rotating rod 27 and the shaft of the third differential gears 32 located on the fixing plate 30, with third chains 34 sleeved on the two differential sprockets 33, the third chains 34 meshing with the two differential sprockets 33.

[0053] In this embodiment, when the tower rod 3 needs to be lowered, the servo motor 8 drives the connecting block 2 to start rotating. After the connecting block 2 rotates, the second differential gear 31 rotates accordingly. When the second differential gear 31 rotates, it drives the third differential gear 32 on its shaft to rotate. Since the two differential sprockets 33 are fitted with a third chain 34 and the third chain 34 meshes with the two differential sprockets 33, when one of the differential sprockets 33 rotates, through the transmission action of the third chain 34, it will drive the other differential sprocket 33 fixedly fitted on the rotating rod 27 to rotate, thereby causing the rotating rod 27 to rotate. When the rotating rod 27 rotates, the third differential gear 32 on the rotating rod 27... When the second sprocket 28 rotates, it drives the second sprocket 28 on the shaft of the first sprocket 25 to rotate through the second chain 29, which in turn causes the first sprocket 25 to rotate. The rotation of the first sprocket 25 drives the first sprockets 25 on the two bidirectional screws 10 to rotate synchronously through the first chain 26, thereby causing the two bidirectional screws 10 to rotate. The rotation of the bidirectional screws 10 causes the threaded cylinders 11 on them to slide relative to each other, thereby causing the collection nets 6 to slide and fold relative to each other and be stored, thus realizing the folding and storage of the collection nets 6 while the tower pole 3 is being laid down.

[0054] In a further preferred embodiment of the present invention, a protective cover 35 for protecting the linkage mechanism is installed on the fixing plate 30, and the protective cover 35 is fixedly connected to the protective cover 24.

[0055] In this embodiment, after the protective cover 35 is fixedly connected to the protective cover 24, it can enclose the linkage mechanism inside, preventing seawater, sand, salt spray and other substances from directly contacting the various parts of the linkage mechanism, and avoiding damage to these parts due to corrosion and wear.

[0056] To further improve the performance of this device, in addition to the above-mentioned solutions, this solution also includes the following embodiments:

[0057] In another embodiment of the present invention, a support rod 36 is provided on the ship deck to assist in supporting the water collection tank 7, and the support rod 36 is connected to the mounting plate of the water collection tank 7 by bolts.

[0058] In this embodiment, the support rod 36 supports the water collection tank 7, which effectively improves the stability of the collection net 6, enabling it to remain relatively stable in the sea breeze environment and ensuring the normal operation of the collection net 6.

[0059] In another embodiment of the present invention, a fixing mechanism for fixing the tower 3 is provided on the right side of the base 1. The fixing mechanism includes: a disc 37 fixedly installed on one side of the tower 3; a first support frame 38 and a second support frame 42 provided on the ship deck for supporting the tower 3; a hydraulic cylinder 39 installed on one side of the inner wall of the first support frame 38, and a connecting plate 40 is installed on the hydraulic cylinder 39; an electric suction cup 41 fixedly installed on one side of the connecting plate 40, the electric suction cup 41 being used to attract the disc 37 and fix the tower 3; and a limiting mechanism provided on the connecting plate 40 for reinforcing the tower 3.

[0060] In this embodiment, after the tower 3 is laid down, it needs to be fixed to prevent it from shaking or shifting. At this time, the hydraulic cylinder 39 is activated to start working and generate telescopic movement, pushing the connecting plate 40 towards the disc 37. As the connecting plate 40 moves, the electric suction cup 41 also gradually approaches the disc 37. When the electric suction cup 41 is in close contact with the disc 37, the electric suction cup 41 is activated, generating suction force and firmly adhering to the disc 37, thereby achieving the initial fixation of the tower 3.

[0061] Meanwhile, the limiting mechanism further reinforces the tower 3 and restricts it to prevent it from rotating or moving laterally when subjected to external forces, ensuring that the tower 3 remains stable when it is lowered. In addition, the first support frame 38 and the second support frame 42 will also jointly bear the weight of the tower 3, providing a stable support foundation for the tower 3. Together with the electric suction cup 41 and the limiting mechanism, they ensure the stability of the tower 3 after it is lowered.

[0062] In another embodiment of the present invention, the limiting mechanism includes: a threaded rod 43 rotatably mounted on the connecting plate 40, a rectangular cylinder 44 threadedly sleeved on the threaded rod 43, the rectangular cylinder 44 being slidably connected to a rectangular groove on one side of the tower rod 3; a first sealing ring 45 sleeved on the rectangular cylinder 44 for sealing the gap between the rectangular cylinder 44 and the rectangular groove; and a guide rod 46 fixedly mounted on one side of the connecting plate 40 for guiding the rectangular cylinder 44, the guide rod 46 being slidably connected to the rectangular cylinder 44.

[0063] In this embodiment, when the connecting plate 40, driven by the hydraulic cylinder 39, moves the electric suction cup 41 closer to the disc 37 to achieve initial adsorption and fixation of the tower rod 3, at the same time, the threaded rod 43 mounted on the connecting plate 40 begins to rotate. During the rotation of the threaded rod 43, the rectangular tube 44 slides to one side along the axial direction of the threaded rod 43. As the rectangular tube 44 slides, it gradually inserts into the rectangular groove on the tower rod 3. When the rectangular tube 44 is inserted into the rectangular groove, the first sealing ring 45 undergoes elastic deformation, filling the gap between the rectangular tube 44 and the rectangular groove, thus achieving a sealing effect. At this time, the electric suction cup 41 has been adsorbed onto the disc 37, and the rectangular tube 44 is inserted into the rectangular groove and cooperates with the electric suction cup 41 to restrict the tower rod 3 from different directions.

[0064] In another embodiment of the present invention, a connecting plate 47 is fixedly installed on the connecting plate 40, a rack 48 is fixedly installed on one side of the inner wall of the first support frame 38, a driven gear 49 is fixedly installed on one side of the connecting plate 47, the driven gear 49 meshes with the rack 48, and a fourth differential gear 50 is fixedly sleeved on both the rotating shaft and the threaded rod 43 of the driven gear 49, and the two fourth differential gears 50 mesh with each other.

[0065] In this embodiment, when the hydraulic cylinder 39 starts working and drives the connecting plate 40 to slide to one side, during the sliding process of the connecting plate 40, the driven gear 49 will rotate along the rack 48. When the driven gear 49 rotates, its rotational force will be transmitted to the fourth differential gear 50 on the threaded rod 43 through the fourth differential gear 50 connected to it, thereby driving the threaded rod 43 to rotate. When the threaded rod 43 rotates, the rectangular cylinder 44 will slide along the axial direction of the threaded rod 43 and insert into the rectangular groove, ultimately achieving the limiting and fixing of the tower rod 3.

[0066] In another embodiment of the present invention, the tower 3 is provided with a stabilizing mechanism for secondary reinforcement of the tower 3. The stabilizing mechanism includes: a slot formed on the second support frame 42; a piston cavity 51 formed on the tower 3; a piston block 52 slidably disposed in the piston cavity 51 and adapted to the slot; a round rod 53 fixedly installed in the piston cavity 51 and slidably connected to the piston block 52; a return spring 54 sleeved on the round rod 53 and fixedly connected to the piston cavity 51 and the piston block 52 respectively; a second sealing ring 55 sleeved on the piston block 52 for sealing the gap between the piston block 52 and the piston cavity 51; and a through-hole 56 formed in the tower 3 and communicating with the piston cavity 51 and the rectangular groove.

[0067] In this embodiment, when the rectangular cylinder 44 is inserted into the rectangular groove on the tower rod 3, the first sealing ring 45 seals the gap between the rectangular cylinder 44 and the rectangular groove, so that the air in the rectangular groove cannot escape from the gap during the insertion of the rectangular cylinder 44. As the rectangular cylinder 44 continues to go deeper into the rectangular groove, the air in the rectangular groove is compressed and the air pressure gradually increases. The compressed air rushes into the piston chamber 51 through the port 56.

[0068] When high-pressure air enters the piston chamber 51, it exerts an outward thrust on the piston block 52, pushing the piston block 52 to slide outward along the round rod 53. At the same time, the round rod 53 provides guidance for the sliding of the piston block 52. The return spring 54 is stretched during the sliding of the piston block 52, generating a reverse pulling force. When the piston block 52 is pushed out of the piston chamber 51 a certain distance under the action of air pressure, it slides into the slot. At this time, the piston block 52 is stuck in the slot, generating an additional constraint force on the tower rod 3. This, together with the adsorption force of the electric suction cup 41 and the limiting force of the rectangular tube 44, reinforces the fallen tower rod 3 and prevents the tower rod 3 from shaking or shifting in the harsh marine environment.

[0069] In summary, compared with related technologies, this device can achieve multiple functions such as wind power generation and sea fog collection. It can also store equipment to prevent damage in extreme weather conditions and is equipped with multiple reinforcement and auxiliary support designs to ensure operational safety.

[0070] It should be understood, in the several embodiments provided in this application, that the disclosed apparatus may be implemented in other ways.
