DETAILED DESCRIPTION

[0027] The present invention will be described in further detail below with reference to the accompanying drawings.

[0028] like Figure 1 、 Figure 2 、 Figure 3 As shown, a soft wing sail includes a base 1, a lower support frame 2, an upper support frame 3, a sail body bracket 4, a flap bracket 5, a soft sail body 6, a soft flap 7 and a lifting mechanism 8.

[0029] like Figure 1 、 Figure 2 、 Figure 3 As shown, the base 1 is installed on the deck of a ship, a rotating shaft 11 is vertically connected to the base 1, and a driving mechanism 12 for controlling the rotation of the rotating shaft 11 is provided in the base 1.

[0030] like Figure 1 、 Figure 2 、 Figure 3 As shown, the driving mechanism 12 includes a first motor 13, a first gear 14 and a first gear ring 15. The first motor 13 is disposed in the base 1, the first gear 14 is disposed on the first motor 13, and the first gear ring 15 is disposed on the outer wall of the rotating shaft 11 and meshes with the first gear 14.

[0031] like Figure 1 、 Figure 2 、 Figure 3 As shown, the lower support frame 2 is horizontally arranged above the rotation axis 11, and the upper support frame 3 is horizontally arranged above the lower support frame 2. The sail body support 4 is vertically arranged between the lower support frame 2 and the upper support frame 3, and the flap support 5 is vertically arranged between the lower support frame 2 and the upper support frame 3.

[0032] like Figure 1 、 Figure 2 、 Figure 3As shown, the soft sail body 6 is vertically slidably connected to the sail body bracket 4, and the soft flaps 7 are vertically slidably connected to the flap bracket 5. Therefore, when the wind direction cannot provide power for the ship, the soft sail body 6 and the soft flaps 7 can be lowered and stored to avoid resistance caused by the sail, thereby ensuring normal navigation of the ship.

[0033] like Figure 1 、 Figure 2 、 Figure 3 As shown, the lifting mechanism 8 is used to control the lifting of the soft sail body 6 and the soft flap 7 , and the lifting mechanism 8 includes a speed reducer 81 , a winch 82 , a cable 83 and a pulley 84 .

[0034] like Figure 1 、 Figure 2 、 Figure 3 As shown, a speed reducer 81 is disposed within the lower support frame 2, a winch 82 is disposed on the speed reducer 81, and a cable 83 is wound around the winch 82, passing through the sail support 4 or the flap support 5, and then fixed to the upper end of the soft sail 6 or the soft flap 7. Pulleys 84 are disposed at the upper and lower ends of the sail support 4 or the flap support 5, and are provided for the cable 83 to pass over.

[0035] When the wind direction is suitable for providing power to the ship, the reducer 81 drives the winch 82 to rotate, and the winch 82 is used to reel in the cable 83. At this time, the cable 83 can be used to pull up the soft sail 6 and the soft flap 7, and the soft sail 6 and the soft flap 7 can be deployed. At the same time, the first motor 13 can also be used to control the rotation of the first gear 14, and with the cooperation of the first gear ring 15, the entire sail can be controlled to rotate, and the angle of the entire sail can be adjusted to meet the needs of the sail and provide power to the ship.

[0036] When the wind direction cannot provide power for the ship, the reducer 81 is used to drive the winch 82 to rotate in the opposite direction, and the winch 82 is used to reel in the cable 83. At this time, under the action of the gravity of the soft sail body 6 and the soft flap 7, the soft sail body 6 and the soft flap 7 are automatically lowered and stored, avoiding resistance generated by the sail, thereby ensuring the normal navigation of the ship.

[0037] like Figure 1 、 Figure 2 、 Figure 3 As shown, the soft sail 6 includes a sail frame 61 and a sail body 62. The sail frames 61 are arranged at intervals, and the sail body 62 is arranged between two adjacent sail frames 61. The soft flap 7 includes a flap frame 71 and a flap body 72. The flap frames 71 are arranged at intervals, and the flap body 72 is arranged between two adjacent flap frames 71.

[0038] Therefore, the structural strength of the soft sail body 6 and the soft flap 7 is ensured by setting the frame, and stable stacking can be achieved when stored, ensuring stability during storage, and also ensuring the stability of the soft sail body 6 and the soft flap 7 when working.

[0039] like Figure 1 、 Figure 2 、 Figure 3 As shown, the sail support 4 includes a main sail support 41 and a pair of auxiliary sail supports 42, with the pair of auxiliary sail supports 42 being distributed on both sides of the main sail support 41. Therefore, the high structural strength of the sail support 4 can improve its stability, ensure stable support for the soft sail 6, and improve the working stability of the soft sail 6.

[0040] like Figure 1 、 Figure 2 、 Figure 3 As shown, the flap bracket 5 is rotatably connected to the upper support frame 3 and the lower support frame 2, a second motor 21 is provided in the lower support frame 2, a second gear 22 is provided on the second motor 21, and a second gear ring 23 meshing with the second gear 22 is provided at the lower end of the flap bracket 5.

[0041] Therefore, by providing a rotatable soft flap 7, the angle of attack of the sail body and the angle of the flap relative to the sail body can be adjusted according to the wind direction, which can maximize the use of wind energy, ensure that sufficient propulsion energy can be obtained, and ensure the normal navigation of the ship.

[0042] The specific embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the embodiments as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
