Description

Technical Field

[0001] The utility model relates to the field of sail design, in particular to a retractable and foldable device that combines solar power generation technology with sails, and is applicable to fishing boats, yachts and other types of ships. Background Art

[0002] Sails are the main power source for sailboats. In recent years, with the global emphasis on environmental protection and sustainable development, the shipping industry is facing great pressure to reduce emissions and energy consumption. The solar panels of existing sailboats are generally installed on the hulls of sailboats. At the same time, for modern sailboats, a design that combines a mast and a flexible fabric triangular sail is usually adopted, and ropes fixed at the corners of the sail are used to contract or expand the sail to achieve a specific shape.

[0003] However, such sails have the following problems: On some ships, especially small fishing boats and sailboats, the upper structure is limited, and installing and fixing large-area solar panels will occupy valuable space, hindering the operation of the crew and the flexibility of the ship. At the same time, the folding method of traditional sails is too complex, involving ropes with different functions, resulting in low efficiency of furling the sail. Summary of the Utility Model

[0004] In order to overcome the problem that sails cannot make full use of solar energy and the problem of sail folding, the utility model combines flexible solar panels with sail canvas and uses a folding fan type folding to complete the contraction of the sail. Thus, the efficient utilization of solar energy by the sail is completed, and the sailing efficiency of the ship is improved.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a folding fan type solar sail, including a mast, a conical fixing buckle is provided at the bottom of the mast, a diagonal stay sail rod, a diagonal pull sail rod, a flexible solar panel, canvas, a door leaf, a first sleeve joint, a second sleeve joint, a third sleeve joint, and the sail canvas is made of a lightweight, high-strength and waterproof composite material. The surface of the sail canvas is covered with a flexible solar panel. The two sides of the sail are symmetrical, and there are three flexible solar panels on one side, all of which are coaxially matched with the door leaf. The first flexible solar panel is coaxially matched with the mast through the door leaf. The second flexible solar panel is coaxially matched with the first flexible solar panel through the door leaf. The third flexible solar panel is coaxially matched with the second flexible solar panel through the door leaf. The diagonal stay sail rod is coaxially matched with the third flexible solar panel. The diagonal stay sail rod is coaxially matched with the mast through the first sleeve joint. The diagonal pull sail rod is coaxially matched with the mast through the second sleeve joint. The diagonal pull sail rod is coaxially matched with the diagonal stay sail rod through the third sleeve joint.

[0006] For the above-mentioned folding fan type solar sail, the flexible solar panel is a regular trapezoid, the upper apex angle is 15 degrees, the lower base angle is 75 degrees, and the axis of symmetry of the regular trapezoid and the upper base are aligned with the first sleeve joint.

[0007] For the above-mentioned folding fan-shaped solar sail, the second sleeve joint is above the first sleeve joint. The first sleeve joint cannot slide up and down relative to the mast, while the second sleeve joint can slide up and down relative to the mast.

[0008] For the above-mentioned folding fan-shaped solar sail, there is a circular ring buckle on the side of the second sleeve joint, which can be connected to a rope, and the rope can be fixed to the conical fixing buckle at the bottom of the mast.

[0009] For the above-mentioned folding fan-shaped solar sail, the third sleeve joint is fixed to the end of the diagonal stay sail rod.

[0010] The beneficial effects of the present utility model are as follows: The folding fan-shaped solar sail of the present utility model uses flexible solar panels to cover the surface of the canvas, forming a sail with power generation function, making full use of wind energy and solar energy, and effectively utilizing the space of the ship. At the same time, the flexible solar panels adopt a folding fan-shaped design, which simplifies the deployment and contraction of the sail, has the characteristics of flexible adjustment and high-efficiency utilization, improves the use efficiency of the sail, and saves time.

Detailed Implementation Modes

[0016] For the folding fan type solar sail, during the implementation process, when the ship is sailing at sea, by pulling the rope, the second shaft sleeve joint 2 starts to slide downward relative to the mast 1, the diagonal stay sail rod 3 drives the diagonal brace sail rod 4 to be propped up, the diagonal stay sail rod 3 rotates counterclockwise relative to the second shaft sleeve joint 2, the diagonal brace sail rod 4 rotates counterclockwise relative to the first shaft sleeve joint 11, the third shaft sleeve joint 10 rotates relative to the diagonal stay sail rod 3, and the first flexible solar panel 5, the second flexible solar panel 6, and the third flexible solar panel 7 are fully unfolded along with the door panel 9. Finally, the rope is fixed on the conical fixing buckle 8. The flexible solar panels on the sail start to receive light energy and generate current. The full utilization of new energy effectively reduces the fuel consumption. In addition, under bad weather conditions, the ship can quickly adjust the canvas to maintain a stable sailing state, reducing potential safety hazards.
