Description

boat sail

technical field

The invention relates to a marine sail, in particular to a marine sail which can automatically control its swinging and raising and lowering actions.

Background technique

A sailboat is a ship powered by wind energy. As a clean and green energy source, wind energy has many advantages. The original ship is no longer applicable, but the sail still has certain significance as the auxiliary power of the ship; the traditional sail needs to lift the sail body according to the wind situation, and at the same time change the sail angle according to the wind direction, so as to increase the windward of the sail as much as possible. However, the above two actions still need to be manually operated by the crew, which is time-consuming, cumbersome, and inefficient. At the same time, when the sails are not needed, the scattered sails are very irregular. Occupies a larger area. In summary, there is a need for a novel marine sail that can solve the above problems.

The sail frame 1 can rotate with the central axis 2 as the axis, and the inclination angle of the rotation does not exceed 45 degrees. The deck on the outside of the two arc tracks 7 is also symmetrically provided with a torsion bracket 3, and a double-rope roller motor 4 is arranged in the hull, and the output end rope rollers of the double-rope roller motor 4 are respectively wound with forward pullers with opposite winding directions. Cable 5 and reverse cable 6, after the two ends of forward cable 5 change direction through fixed pulley respectively, connect with the two ends of sail frame 1 through torsion bracket 3, the two ends of reverse cable 6 pass through fixed pulley equally respectively. After the pulley changes direction, it is connected to both ends of the sail frame 1 by twisting the bracket 3, and there is a height difference between the connection points of the forward stay cable 5 and the reverse stay cable 6 on the sail frame 1 respectively, and the forward stay cable 5 And backstay 6 is in taut state all the time.

Lifting slide rails 8 are arranged on both sides of the sail frame 1, and a plurality of pulleys 9 are arranged along the height direction of the lifting slide rails 8.

Detailed ways

The specific implementation manner of the present invention will be described below with reference to the accompanying drawings. As shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6 and Fig. 7: a kind of marine sail includes a sail frame 1, on which polyester cloth is connected, and the central axis 2 of the sail frame 1 is fixed On the hull, two ends of the sail frame 1 are provided with rollers located on the deck of the hull, and symmetrical arc tracks 7 are arranged on both sides of the sail frame 1, and the arc track 7 can limit the swing range of the sail frame 1; The sail frame 1 can rotate around the central axis 2, and the inclination angle of the rotation does not exceed 45 degrees, and a torsion bracket 3 is symmetrically arranged on the deck outside the two arc-shaped tracks 7;

A double-rope roller motor 4 is arranged in the hull, and the output end rope rollers of the double-rope roller motor 4 are respectively wound with a forward stay cable 5 and a reverse stay cable 6, and the winding directions of the two are opposite. After the two ends change the direction through the fixed pulley respectively, they are connected to the two ends of the sail frame 1 through the torsion bracket 3 to form a closed-loop structure; The two ends of the sail frame 1 are connected to form another closed-loop structure; and the forward stay cable 5 and the reverse stay cable 6 form connection points on the sail frame 1, and there is a height difference between the respective connection points, and the forward stay cable 5 and the reverse cable 6 are always in a tight state (as shown in Figure 6 and Figure 7);

Both sides of the sail frame 1 are provided with lifting slide rails 8 arranged along its height direction, and a plurality of pulleys 9 are arranged along the length direction of the lifting slide rails 8, and the heights of the lifting slide rails 8 on both sides are consistent, And also be connected with sail bar 10 between paired pulley 9, be provided with lifting motor 11 in the hull, be wound on the output shaft of lifting motor 11 with a lifting cable 12 that connects end to end, forms closed-loop structure, in On the outer side of the sail frame 1, two fixed pulleys are arranged symmetrically at the positions at the same horizontal height as its upper and lower ends. Among all the sail bars 10, the two ends of the sail bar 10 with the highest horizontal height are respectively connected with one of the pair of double-strand stay cables that can move in the same direction, and the two ends of the lift stay cable 12 respectively connected to both ends of the spring 13 to form a closed state connected end to end (as shown in Figure 4 and Figure 5);

Both ends of each sail bar 10 are rotatably connected with a rotating shaft 14, and the end parts of every two adjacent rotating bars 14 are hinged to each other, and an elastic member 15 is arranged at the hinge point, and the elastic member 15 is respectively connected with The shafts of two adjacent rotating rods 14 are connected, and the two adjacent elastic members 15 in the height direction are respectively located on the front side and the rear side of the rotating rod 14, and are arranged in a staggered state; this structure can ensure that the sails are scattered In the state, it can be folded and placed very regularly to minimize the occupied area (as shown in Figure 1 and Figure 2).

The working process of the embodiment of the present invention is as follows: when the sail needs to be raised, the lifting motor 11 is controlled to work, and the output end of the lifting motor 1 drives the lifting cable 12 to move. Finally, a double-strand cable is formed on both sides of the sail frame 1. During the movement of the lifting cable 12, one of the two double-strand cables moves in the same direction, so they are connected in the same direction of motion. The sail bar 10 on the lifting cable 12 will move upwards, because the adjacent rotating shafts 14 connected to the two ends of the sail bar 10 are hinged with each other, so under the drive of the uppermost sail bar 10, all the sail bars The rods 10 all move upwards, and the sails are opened; when the sails need to be lowered, the lifting motor 11 rotates in the opposite direction, driving the lifting cables 12 to move in the opposite direction, and all the sail bars 10 move downwards, and the sails are folded; In the process, since the elastic parts 15 connected with the shafts of the two rotating rods 14 are arranged at the hinge points of every two adjacent rotating rods 14, and the adjacent two elastic parts 15 are located at the joints of the rotating rods 14 respectively. Both sides (front side and rear side), that is, all elastic members 15 are arranged in a serpentine staggered shape, so that the bending direction of each rotating rod 14 and the bending of the rotating rods 14 adjacent to its upper and lower ends can be guaranteed The directions are all different, and they are arranged in multiple continuous Z shapes. This structure can minimize the volume of the sail when it is folded;

When the sail frame 1 needs to be rotated to obtain a larger area of the windward side, start the double rope roller motor 4, and the forward stay cable 5 and the reverse stay cable 6 that are wound on the output end of the double rope roller motor 4 move. After the two ends of the dragline 5 change direction through the fixed pulley block, they are connected to the two ends of the sail frame 1 by twisting the bracket 3, so when the forward dragline 5 moves, the draglines at the two ends of the sail frame 1 are tight, A loose state, and the forward cable 5 is always in a taut state during the whole movement process; while the reversely wound reverse cable 6 also moves at the same time, and the direction of movement is opposite to that of the forward cable 5, that is, the sail frame 1 The reverse cable 6 at the end is in a loose state and a tight state. The combination of the above two actions realizes the purpose of rotating the sail frame 1 in a certain direction; swing angle, but both sides of the sail frame 1 are also provided with arc tracks 7 for spacing, which can ensure that the maximum swing angle of the sail frame 1 is 45 degrees.

The marine sail of this structure can realize the automatic lifting and swinging of the sail, and at the same time, when the sail is in a scattered state, it can ensure that the sail is stacked together in a relatively regular state, and the footprint of the sail can be reduced as much as possible.
