Technical Field

[0001] The present invention relates to the technical field of ships, and in particular to a sail device and an ocean freighter. Background Art

[0002] In the global commodity transportation network, shipping plays a very important role. 90% of the global import and export trade is achieved through shipping. Modern shipping has become a main force in global trade transportation due to its large transportation capacity, low transportation unit price, and relatively high transportation reliability. In view of this situation, the power reform of ship transportation can save a large amount of energy. Especially today, when most ships are still using non-renewable energy such as diesel and coal, the development of clean new marine power is of great value. This also makes a great contribution to reducing global greenhouse gas emissions and building a green global homeland.

[0003] Existing large ocean-going transport ships generally range from tens of thousands to hundreds of thousands of tons, and are mainly driven by internal combustion engines. In order to save energy and utilize the offshore wind energy, large sails have been developed at home and abroad, and the wind energy is converted into kinetic energy through the sails.

[0004] However, the sail surface of the sail is generally made of aluminum alloy, resulting in an overweight of the entire system. The sail surface cannot be made large enough. At the same time, the sail surface is composed of three or more sections, similar to the form of Russian nesting dolls. The lifting mechanism is very complex and is prone to failure under high loads. Moreover, after the sail surface is stored, there is finally a large area of the sail surface exposed on the deck and cannot be truly stored, making it vulnerable to damage. Summary of the Invention

[0046] The present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0047] The specific structure is as Figures 1 to 5 shown.

[0048] This embodiment provides a sail device installed on a hull, including: a soft sail, a column, a fixed bracket 4, a lifting mechanism, and a storage cabinet 7;

[0049] One end of the column is connected to the hull, and the other end is connected with a fixed bracket 4 for fixing the soft sail;

[0050] A storage cabinet 7 is correspondingly arranged below the fixed bracket 4;

[0051] The lifting mechanism is connected to the soft sail and is used to raise or lower the soft sail;

[0052] The soft sail rises so that the soft sail is in contact with the fixed bracket 4;

[0053] The soft sail descends so that the soft sail enters the storage cabinet 7.

[0054] In this embodiment, an opening and closing oil cylinder 8 is arranged on one side of the storage cabinet 7. The opening and closing oil cylinder 8 is connected to the cabinet door at the top of the storage cabinet 7 for opening and closing the cabinet door. The bottom end of the column is fixedly connected to the deck of the hull, and the fixed bracket 4 is connected to the side wall at the top end of the column. When raising the sail, the lifting mechanism drives the soft sail to rise until it is in contact with and fixed to the fixed bracket 4. When furling the sail, the lifting mechanism drives the soft sail to descend, and at the same time, the fixed bracket 4 is separated from the soft sail, and the soft sail falls into the storage cabinet 7 in sequence from bottom to top for storage.

[0055] The sail device provided in this embodiment has a relatively small overall structural weight. It can increase the area of the soft sail, adding a relatively small load to the hull while utilizing wind energy. The soft sail itself can be folded and completely stored in the storage cabinet 7, preventing the soft sail from being damaged in harsh environments, with high reliability. At the same time, the structure is simple and the cost is low.

[0056] In an alternative technical solution of this embodiment, the fixed bracket 4 includes a first connecting rod 17 and a second connecting rod 18. The first connecting rod 17 is connected to the column through the second connecting rod 18.

[0057] One end of the second connecting rod 18 is connected to the column, and the other end is connected to the first connecting rod 17.

[0058] The storage cabinet 7 is correspondingly arranged below the first connecting rod 17.

[0059] In this embodiment, the first connecting rod 17 is connected to the column through one second connecting rod 18. The second connecting rod 18 is connected in the middle of the first connecting rod 17 and is perpendicular to the first connecting rod 17. With this arrangement, the structure is simple and the installation is convenient.

[0060] In an alternative technical solution of this embodiment, the first connecting rod 17 is connected to the column through two second connecting rods 18. The two ends of the first connecting rod 17 are respectively connected to the second connecting rods 18. A triangular structure is formed among the first connecting rod 17, the two second connecting rods 18, and the column. Thus, it also has the technical advantages and effects of the above-mentioned embodiment, which will not be elaborated here. At the same time, the structure of this embodiment is stable and not easily deformed.

[0061] In an alternative technical solution of this embodiment, the first connecting rod 17 is connected to the column through three second connecting rods 18. The two ends and the middle of the first connecting rod 17 are respectively connected to the second connecting rods 18. A triangular structure is formed among the first connecting rod 17, the second connecting rods 18 at both ends of the first connecting rod 17, and the column. The second connecting rod 18 connected to the middle of the first connecting rod 17 is perpendicular to the first connecting rod 17 and is located on the perpendicular bisector of the triangular structure. Thus, it has the technical advantages and effects of the above-mentioned embodiment, which will not be elaborated here. At the same time, since the second connecting rod 18 is located on the perpendicular bisector of the triangular structure, it has a supporting effect, and the overall structure is more stable and less likely to deform.

[0062] Preferably in this embodiment, the first connecting rod 17 and the second connecting rod 18 are integrally formed, which is convenient for manufacturing and the structure is firm.

[0063] In an alternative technical solution of this embodiment, the column includes a fixed column 1, a rotating column 2, and a rotating mechanism 3.

[0064] One end of the fixed column 1 is connected to the hull, and the other end is connected to the rotating mechanism 3.

[0065] The rotating column 2 is respectively connected to the rotating mechanism 3 and the second connecting rod 18, and the rotating mechanism 3 is located between the fixed column 1 and the rotating column 2.

[0066] In this embodiment, the fixed column 1 is fixedly connected to the deck of the hull. The top end of the fixed column 1 is connected to the rotating mechanism 3. The rotating mechanism 3 can be a turntable, a bearing, a speed reducer, etc. The rotating column 2 is connected to the rotating mechanism 3 and rotates through the rotating mechanism 3. The side wall of the top end of the rotating column 2 is connected to the second connecting rod 18. By rotating the rotating column 2, the direction can be adjusted to cope with the wind coming from different directions.

[0067] In an alternative technical solution of this embodiment, an operation platform 6 is further included, and the operation platform 6 is connected to the rotating column 2;

[0068] The storage cabinet 7 is arranged on the operation platform 6.

[0069] In this embodiment, the bottom side wall of the rotating column 2 is connected to the operation platform 6. The upper surface of the operation platform 6 is fixedly installed with the storage cabinet 7. The storage cabinet 7 is a cuboid cabinet, and the length direction corresponds to the length direction of the first connecting rod 17. When the rotating column 2 rotates, it drives the operation platform 6 to rotate, and then drives the storage cabinet 7 to rotate, so that the relative position between the first connecting rod 17 and the storage cabinet 7 remains unchanged, and the soft sail also rotates with the rotating column 2 to utilize the wind coming from different angles.

[0070] In an alternative technical solution of this embodiment, the lifting mechanism includes a pulley block 11, a cable 10 and a winch 9, and the pulley block 11 has a pulley;

[0071] The pulley block 11 is connected to the first connecting rod 17, and the cable 10 is connected to the soft sail;

[0072] The cable 10 bypasses the pulley, and one end of the cable 10 is connected to the storage cabinet 7 and the other end is connected to the winch 9.

[0073] In this embodiment, a pulley block 11 is arranged at each end of the first connecting rod 17. The pulley block 11 has a pulley. The bottom plate of the storage cabinet 7 is provided with eye plates corresponding to the pulley blocks 11 at both ends of the first connecting rod 17 respectively. Winches 9 are arranged on the left and right sides of the storage cabinet 7 respectively, and the winches 9 correspond to the pulley blocks 11. Cables 10 are respectively connected to the left and right sides of the soft sail. One end of the cable 10 has a thimble 14, and the other end is fixedly connected to the winch 9. The end of the cable 10 with the thimble 14 bypasses the pulley on the pulley block 11 and is fixedly connected to the eye plate through the thimble 14. The pulley divides the cable 10 into a driving end and a driven end. The side of the pulley with the winch 9 is the driving end, and the other side is the driven end. The driven end is connected to the soft sail. By the rotation of the winch 9 and the cooperation of the pulley block 11, the cable 10 can drive the soft sail to lift, with a simple structure and convenient lifting.

[0074] In an alternative technical solution of this embodiment, a pair of pulleys 11 are provided at both ends of the first connecting rod 17. There is a gap between each pair of pulleys 11, and the cable 10 passes around the two pulleys 11. In this way, the lateral distance between the active end and the driven end of the cable 10 is large enough to prevent the active end and the driven end of the cable 10 from contacting and winding around each other during the lifting process, which may affect the lifting.

[0075] Preferably, in this embodiment, the cable 10 is a steel wire rope, which is not easily damaged and has a large bearing strength.

[0076] In an alternative technical solution of this embodiment, the soft sail includes a soft sail surface 15 and a keel frame 5, and the soft sail surface 15 is connected to the keel frame 5.

[0077] In this embodiment, the material of the soft sail surface 15 can be cloth, nylon, plastic, etc. The soft sail surface 15 can be folded, which is convenient for storage and has a small mass. At the same time, it is connected to the keel, and the keel can well support the soft sail surface 15, and the effect of utilizing wind energy is better.

[0078] In an alternative technical solution of this embodiment, the keel frame 5 includes a third connecting rod 19, a fourth connecting rod 20 and an arc rod 21;

[0079] The soft sail surface 15 is connected to the arc rod 21, and both ends of the arc rod 21 are connected to the third connecting rod 19;

[0080] The fourth connecting rod 20 is located between the arc rod 21 and the third connecting rod 19, and one end of the fourth connecting rod 20 is connected to the third connecting rod 19 and the other end is connected to the arc rod 21.

[0081] In this embodiment, both ends of the arc rod 21 are respectively connected to the side walls at both ends of the third connecting rod 19. There are three fourth connecting rods 20 arranged between the arc rod 21 and the third connecting rod 19. One end of the first fourth connecting rod 20 is connected to the middle of the third connecting rod 19 and the other end is connected to the middle of the arc rod 21 to support the arc rod 21 and maintain a certain curvature. The other two fourth connecting rods 20 are respectively located on both sides of the first fourth connecting rod 20 to assist in supporting the arc rod 21 and form an umbrella-like structure, which has a stable structure and is not easily deformed. At the same time, a plurality of mutually corresponding umbrella-like structures are longitudinally arranged at intervals on the keel frame 5, and the soft sail surface 15 is connected to a plurality of arc rods 21. In this way, the soft sail surface 15 can be unfolded large enough to better utilize wind energy. It should be noted that the number of the fourth connecting rods 20 in this embodiment can be one or more, as long as the supporting effect is satisfied.

[0082] In an alternative technical solution of this embodiment, a through hole 16 is provided in the third connecting rod 19. The cable 10 passes through the through hole 16. The cable 10 has a limit knot 12. There is at least one limit knot 12 between the through holes 16 corresponding to adjacent two layers, and the through hole 16 can limit the limit knot 12 from passing through.

[0083] In this embodiment, through holes 16 are provided in the third connecting rods 19 that are longitudinally arranged at intervals in sequence. The through holes 16 are located at both ends of the third connecting rod 19 and correspond to the pulleys on the pulley block 11. The driven end of the cable 10 passes through the through holes 16 in the third connecting rod 19. There is a limit knot 12 between the upper and lower adjacent third connecting rods 19. The distance between two adjacent limit knots 12 is equal to the distance between the third connecting rods 19 corresponding above the two limit knots 12. In this way, when the soft sail rises, the limit knot 12 drives the third connecting rod 19 above it to move upward, and the moving distance is exactly equal to the spacing. When the soft sail descends, the limit knot 12 drives the third connecting rod 19 below it to move downward. In this way, the limit knot 12 drives the third connecting rod 19 to rise or fall. The structure is simple, the lifting is convenient, and the cable 10 can be folded, so that the soft sail surface 15 and the keel framework 5 can all enter the storage cabinet 7, which is convenient for storage.

[0084] Preferably in this embodiment, the limit knot 12 is a knot of the cable 10 itself, which saves costs and is more firmly integrated.

[0085] In an alternative technical solution of this embodiment, a buckle 13 matching the third connecting rod 19 is provided on the first connecting rod 17.

[0086] In this embodiment, a buckle 13 is connected to the first connecting rod 17. The buckle 13 is located on the lower side of the first connecting rod 17. The lengths and positions of the third connecting rod 19 and the first connecting rod 17 correspond to each other, and the third connecting rod 19 can be inserted into the buckle 13. When the soft sail rises, the uppermost third connecting rod 19 can be inserted into the buckle 13 to fix the soft sail. When the soft sail descends, the uppermost third connecting rod 19 can slide out of the buckle 13. Through the buckle 13, the first connecting rod 17 and the uppermost third connecting rod 19 are fixed and separated. The structure is simple and easy to use.
