Problems solved by technology

The existing sail structure is inconvenient to control when folding, and when such a sail is in use, since one of the canvases is fixed on the horizontal rod, when affected by the wind force on the side of the rod, it cannot be borrowed from the horizontal rod. force, it is easy to cause the canvas to loosen, and the sail is not smooth enough in the process of rising and falling, which affects the use
[0003] In addition, although existing sailboat folding structures can be easily folded in the vertical direction, such as CN1876490A, in some sailing operation scenarios, such as the maintenance of the canvas and the reinforcement of the top of the sail body in windy weather, the maintenance of the canvas is required. It is necessary to fold the canvas and lower it to the deck, and then unfold it for inspection one by one. Since the easy-to-crack point of the canvas often appears at the connection between the beam and the canvas, the canvas must be lowered for maintenance. The reinforcement of the top of the sail body also requires the crew to temporarily climb manually to reinforce the high beams

Embodiment 1

[0020] Example 1, such as figure 1 As shown, a folding structure for long-range unmanned sailboats in all sea conditions, including a base 1, a stand 9 is installed above one end of the base 1, the stand 9 adopts a hollow structure, and the stand 9 is internally installed with A plurality of lifting blocks 7, one end of each lifting block 7 is equipped with a beam bar 4, and a canvas 18 is installed on the beam bar 4, and all the beam bars 4 are away from one end of the lifting block 7 through a connecting belt 3 connection, the length of the beam bar 4 decreases successively from top to bottom; the lifting block 7 and the stand 9 are connected by sliding, and the two adjacent lifting blocks 7 are connected to each other, so A lifting mechanism for controlling the rise of the lifting block 7 is also installed in the stand 9.

[0021] Described lifting mechanism comprises traction rope 8, fixed pulley 5, reel 11 and first motor 12 and second motor, all is provided with a secon...

Embodiment 2

[0029] Embodiment 2: a specific structure of a folding structure for a long-range unmanned sailboat in all sea conditions, such as Figure 1-2 As shown, including the base 1, a stand 9 is installed above one end of the base 1, the stand 9 adopts a hollow structure, and a plurality of lifting blocks 7 are installed inside the stand 9, and a crossbeam bar 4 is installed at one end of each lifting block 7, Canvas 18 is installed on the beam bar 4 .

[0030] Adopt sliding connection between lifting block 7 and stand 9, connect mutually between two adjacent lifting blocks 7, also be installed in the stand 9 and be used to control the hoisting mechanism that lifting block 7 rises.

[0031] Hoisting mechanism comprises traction rope 8, fixed pulley 5, reel 11 and first motor 12 and second motor, wherein:

[0032] The reel 11 and the first motor 12 are all arranged in the base 1, the reel 11 is installed on the output shaft of the first motor 12, the fixed pulley 5 is installed on the ...

Abstract

The invention belongs to the technical field of sailing boats, and particularly relates to a folding structure of a sailing boat sail. A foldable sail structure of a full-sea-condition long-voyage unmanned sailboat comprises a base, a vertical frame is installed above one end of the base, the vertical frame is of a hollow structure, a plurality of lifting blocks are installed in the vertical frame, a cross beam rod is installed at one end of each lifting block, and canvas is installed on the cross beam rods; the lifting blocks are connected with the vertical frame in a sliding mode, every two adjacent lifting blocks are connected with each other, and a lifting mechanism used for controlling the lifting blocks to ascend is further installed in the vertical frame.When the structure is used, rising and falling of the canvas can be achieved only by controlling operation of a first motor, the sail of the unmanned sailboat is convenient to unfold and fold, meanwhile, a cloth groove is formed in the inner side of each cross beam rod of the sailing boat, and the canvas penetrates through the cloth grooves, so that it is guaranteed that the canvas can borrow force from the cross beam rods no matter which side of the canvas is blown by wind, the wind resistance strength of the canvas is guaranteed, and the phenomenon that the sailing boat is damaged is avoided.

Description

technical field [0001] The invention belongs to the technical field of sailboats, and in particular relates to a folding structure of sailboat sails. Background technique [0002] Sailing boats are a kind of water vehicle that utilizes wind power to advance. When the sail is facing the wind, the sails are raised, and the wind power drives the hull to move forward. According to the number of masts, sailboats can be divided into single-masted sailboats, two-masted sailboats and multi-masted sailboats; according to the type of ships, there are flat-bottomed and pointed-bottomed sailboats; The existing sail structure is inconvenient to control when folding, and when such a sail is in use, since one of the canvases is fixed on the horizontal rod, when affected by the wind force on the side of the rod, it will not be possible to borrow from the horizontal rod. The force will easily lead to the loosening of the canvas, and the sail is not smooth enough in the process of rising and...
