Problems solved by technology

[0002] With the development of my country's ocean-going fishery, squid fishing has become an important pillar of ocean-going fishery, but squid fishing is often produced in the high seas, far away from the mainland, so it is vulnerable to strong winds and waves, causing ships to sway and fishing lines to tilt, such as in weather In the changeable Northwest Pacific Ocean, the high-intensity low pressure in the Northwest Pacific Ocean after October will easily affect the stability of the squid fishing boat. How to reduce the yaw of the ship and improve the sag of the fishing line has become an urgent problem to be solved

Embodiment 1

[0014] Such as figure 1 , 2 Shown, a kind of anti-rolling squid fishing boat stern sail, comprises the rotating shaft 3 that is connected with tail sail 2, and rotating shaft 3 is installed in the stern of squid fishing boat 1, and the structural shape of tail sail 2 is " butterfly shape ", and traditional tail sail is two The block-like right-angled trapezoid adjusts the windward angle to reduce the sway of the ship through the middle rotating shaft. The present invention imitates the shape of butterfly wings and designs a tail sail 2 similar to butterfly wings. Through the middle rotating shaft, the windward angle is adjusted, which is different from traditional tail sails. In contrast, the tail sail 2 of the present invention can not only buffer the impact of the wind on the ship, reduce the sway, but also increase the sag of the fishing line, avoid the winding and breaking of the fishing line, and improve the catch output.

[0015] The surface of the tail sail 2 is evenly...

Embodiment 2

[0017] Such as figure 2 , 3 As shown, the optimization scheme of this embodiment on the basis of Embodiment 1 is as follows: the tail sail 2 is composed of an upper sail 201 and a lower sail 203, and an adjustment hole 202 is arranged between the upper and lower sails. By utilizing the aerodynamic characteristics of butterfly flight, the upper sail 201 When the wind blows with the lower sail 203, it will produce a large momentary resistance. The upper sail 201 and the lower sail 203 will produce resistance when the wind blows, but the resistance produced when the upper and lower sails are floated is smaller than that of the upper and lower sails. The swing frequency is different, so that the flexibility of the tail sail 2 can be greatly enhanced, and the windward resistance of the tail sail 2 can be reduced, so that the tail sail 2 can keep the bow of the ship facing the wind and reduce the steering effect of the ship. The area of ​​the upper sail 201 and the lower sail 203 ...

Embodiment 3

[0020] Such as Figure 4 As shown, the optimization scheme of this embodiment on the basis of Embodiment 1 is: the canvas 207 is woven by a warp thread group and a weft thread group, and the warp thread group includes polyvinyl alcohol fibers 207a and spandex elastic fibers 207b arranged side by side, and the weft threads The group includes coconut charcoal fibers 207c and polyimide fibers 207d arranged side by side. The structure of the present invention adopts two warp threads and two weft threads to weave to change the structure of the conventional separate warp and weft threads. The obtained canvas 207 woven by the present invention The distribution structure is tighter, the firmness is higher, and it has high elasticity and recovery effect. The canvas 207 will not be damaged when encountering large waves, even if something is scraped against the canvas 207. Because the canvas 207 has good elasticity It can be stretched so it is not easy to be damaged, and the canvas 207 h...

Abstract

The invention discloses a novel squid-fishing-boat tail sail capable of reducing shaking, and belongs to the technical field of fishery. A novel squid-fishing-boat tail sail capable of reducing shaking includes a rotating shaft connected with the tail sail; the rotating shaft is installed at the stern of a squid fishing boat, and the tail sail is structurally shaped like a butterfly; a traditionaltail sail refers to two same right-angled trapezoids, and oscillation of the boat is reduced by adjusting the angle facing the wind through the middle rotating shaft. The tail sail imitates the shapeof the wing of a butterfly, the tail sail shaped like the wing of the butterfly is designed, and the angle facing the wind is adjusted through the middle rotating shaft. Compared with a traditional tail boat, the tail boat not only can buffer the impact of wind on the boat, oscillation is reduced, the sagging degree of a fish line can be increased, twining and breaking of the fish line are avoided, and the yield of fishing is improved.

Description

technical field [0001] The invention belongs to the field of fishery, and in particular relates to a stern sail for anti-rolling squid fishing boats. Background technique [0002] With the development of my country's ocean-going fishery, squid fishing has become an important pillar of ocean-going fishery, but squid fishing is often produced in the high seas, far away from the mainland, so it is vulnerable to strong winds and waves, causing ships to sway and fishing lines to tilt, such as in weather In the changeable Northwest Pacific Ocean, the high-intensity low pressure in the Northwest Pacific Ocean after October will easily affect the stability of squid fishing boats. How to reduce the yaw of the ship and improve the sag of the fishing line has become an urgent problem to be solved . Contents of the invention [0003] The object of the present invention is to provide a kind of anti-rolling squid fishing boat stern sail which can reduce the yaw of the ship, improve the v...
