Description

Technical Field

[0001] The present invention relates to the technical field of shipbuilding, and in particular to an intelligent sail steering device for a ship and a manufacturing method thereof. Background Art

[0002] The carrying capacity of ships far exceeds that of other modes of transportation. A large container ship can carry tens of thousands of standard containers, while a truck or a train can only carry a relatively limited amount. This enables ships to achieve economies of scale when transporting large quantities of goods, with lower transportation costs per unit of goods. The cost advantage of ship transportation is even more obvious for long-distance transportation. For example, the transportation cost of airplanes in transoceanic transportation is extremely high, while the transportation range of trucks and trains is limited. Ships can use the vast space of the ocean to sail long distances at a relatively stable speed, and there is no need for frequent transfers and loading and unloading during transportation, which reduces cargo damage and time costs.

[0003] Installing sails on ships can use natural wind power to provide thrust for ships, thereby reducing dependence on fuel. This advantage is particularly prominent in the current situation where oil prices fluctuate greatly and energy supply is unstable. Ships can adjust the angle and area of ​​the sails according to wind direction and wind conditions to maximize the use of wind energy and reduce fuel consumption. There are many types of sails. Cylindrical sails can use the Magnus effect to generate thrust for ships, which can significantly reduce energy consumption when assisting ships in turning. Using wind energy on the sea surface to drive the rotation of cylindrical sails can further reduce energy consumption. However, existing sails cannot be intelligently controlled according to wind direction, and the angle and direction of the sails are fixed, which also has a low utilization rate of wind energy.

According to the position of the wind direction indicating part 3, the position of the specific interval segment of the circumference of the pointing tube assembly 7 can be determined; the wind shield plate assembly 5 is multiple and evenly distributed in the circumference of the rotating tube assembly 1. When the wind direction detection device 4 detects the current wind direction, the driving device drives the pointing tube assembly 7 to rotate, so that the wind shield plate assembly 5 rotates with the rotating tube assembly 1 to an interval position approximately perpendicular to the wind direction and overlaps with the specific interval segment of the circumference of the pointing tube assembly 7.

[0040] By adjusting the angular position of the pointing cylinder assembly 7, the windshield assembly 5 on the rotating cylinder assembly 1 can be rotated to a specific position during the rotation process, thereby obtaining a larger windward area at the specific position, and effectively utilizing wind energy to drive the rotating cylinder assembly 1 to rotate.

[0041] According to the attached Figure 2-5 The pointing cylinder assembly 7 includes a rolling support assembly 71, a pointing gear ring 72, a guide portion 73, a pointing drive gear 74, a drive motor 75 and a support rail 76; the bottom of the pointing cylinder assembly 7 is supported on a support base 6 connected to the hull through a rotating support structure, and the bottom of the pointing cylinder assembly 7 is also provided with a pointing gear ring 72 accommodated in the rotating base 2, the pointing gear ring 72 is meshed with the pointing drive gear 74 at the output end of the drive motor 75, and the driving motor 75 drives the pointing cylinder assembly 7 to rotate according to the current wind direction; the pointing gear ring 72 protrudes from the pointing cylinder assembly 7, and the pointing gear ring 72 is provided on the supporting base 6 connected to the hull. A support rail 76 for supporting the rotating cylinder assembly 1 is arranged on the upper end surface of the directional gear ring 72, and a plurality of rolling support assemblies 71 are evenly arranged on the upper circumference of the directional cylinder assembly 7, and the inner wall of the rotating cylinder assembly 1 abuts against the rolling support assemblies 71; an annular guide portion 73 extending along the circumference is also arranged on the upper portion of the directional cylinder assembly 7, and when the rotating cylinder assembly 1 rotates relative to the directional cylinder assembly 7, the guide portion on the windshield assembly 5 moves along the guide portion 73, and the windshield assembly 5 is driven to rotate relative to the rotating cylinder assembly 1 by changing the path of the guide portion 73.

When the pointing tube assembly 7 is driven to rotate and the wind direction indicating portion 3 is directed to the current wind direction, the line connecting the contour points of the midpoint of the elevated section 733 and the center of the pointing tube assembly 7 is perpendicular to the wind direction. Specifically, when the current wind direction is the first direction, the direction perpendicular to the first direction is the second direction. The pointing tube assembly 7 is rotated so that the line connecting the midpoint of the raised section 733 and the iso-elevation point of the center of the pointing tube assembly 7 is consistent with the second direction.

[0045] A plurality of rows of windshield assemblies 5 are arranged on the rotating drum assembly 1, and the upper and lower rows of windshield assemblies 5 are staggered so that the upper and lower rows of windshield assemblies 5 successively expand the windward area when passing through specific positions, making the driving force of the rotating drum assembly 1 more stable.

[0046] The roller assembly 15 includes a base 151, an axle 152 and a roller 153. The base 151 is arranged on the lower end surface of the rotating cylinder assembly 1. Two rotatable axles 152 are arranged side by side on the base 151. Two rollers 153 are arranged on the axle 152. The rollers 153 are rollingly supported on the support guide rail 76 pointing to the cylinder assembly 7.

[0047] According to the attached Fig. 9 The windshield assembly 5 includes a crank assembly 51 and a wind plate assembly 52. ​​The crank assembly 51 is arranged at one end of the wind plate assembly 52. ​​The crank assembly 51 includes a connecting plate 511, a driving handle 512, a steering support handle 513, and a driving wheel 514.

The driving handle 512 and the steering support handle 513 are vertically arranged with the connecting plate 511. The end of the driving handle 512 is slidably matched with the guide portion 73 of the pointing cylinder assembly 7 through the driving wheel 514.

The steering support handle 513 is connected to the wind plate assembly 52; the wind plate assembly 52 includes a base plate 521, and an arc surface 522 arranged on the base plate 521.

[0048] When the rotating cylinder assembly 1 rotates relative to the pointing cylinder assembly 7, after the driving wheel 514 enters the elevated section 733 from the equal height section 731 through the transition section 732, the steering support handle 513 is driven to rotate through the connecting plate 511, thereby rotating the wind plate assembly 52 from a horizontal state to a vertical state to increase the windward area. In an embodiment of the present invention, when the driving wheel 514 is in the equal height section 731, since the equal height section 731 is at the same height as the steering support handle 513 in the wind plate rotating seat 11, the connecting plate 511 together with the wind plate assembly 52 maintain a horizontal state. When the driving wheel 514 enters the elevated section 733, since the height of the elevated section 733 is higher than the height of the steering support handle 513 in the wind plate rotating seat 11, the driving wheel 514 causes the connecting plate 511 together with the wind plate assembly 52 to be transformed into a vertical state, so that the wind plate assembly 52 enters a vertical state each time it rotates to the elevated section 733, thereby obtaining a larger windward area at this specific position, which is conducive to driving the rotating cylinder assembly 1 to rotate with the help of wind force.
