Description

  The present invention relates to a main engine and a propulsion device that is driven by the main engine, and also relates to a ship including a side sail formed of a hard sail as a propulsion assist, and a method for storing and deploying the side sail.

In order to reduce the total amount of carbon dioxide (CO ₂ ) emitted by a ship, it is effective to reduce the amount of carbon dioxide emitted not only by new ships but also by many existing ships. As an energy-saving device that can be installed on an existing ship, there is an energy-saving additive installed around the propeller. However, with regard to this energy-saving additive, performance improvement has progressed so far, and it is considered difficult to dramatically improve the performance in the future. It has been. Therefore, in addition to these energy-saving addenda, the development of new energy-saving devices that can be installed on existing ships has become an important issue.

  In this connection, dozens of cargo ships equipped with sails were built in the 1980s, including domestic ships and outer bulk carriers, and their effects have already been demonstrated. These sailing vessels have a relatively small sail area, so the energy saving effect of this auxiliary sail is limited, but without significantly affecting the maneuvering, visibility, structure, outfitting, etc. It can be easily attached to an existing ship and is a candidate for a newly required energy-saving device.

  For hard sails equipped on large merchant ships that are premised on this sailing, a mechanism for contracting sails is important, and many proposals and developments have been made. This is an important issue in terms of securing visibility, improving maneuvering in strong winds, anchoring, improving performance on landing berths, reducing aerodynamic drag in the headwind.

  In this connection, the hard sail assembly is formed by nestingly arranged multi-stage wing cross-section cylindrical hard sails, and the upper-stage hard sails are nested and stored in the lower-stage hard sails in sequence. A sailing ship having a hard sail is proposed (for example, see Patent Document 1).

  However, the nested hard sails used in sailing boats equipped with these hard sails have wing surfaces formed on both the front and back sides, which increases the weight of the sail and deploys it in a pantograph manner. In addition, there is a problem that a hydraulic jack, a driving device, and the like for storage are increased in size.

Hereinafter, with reference to the drawings, a description will be given of a ship (hereinafter referred to as a ship) having a side sail formed by a hard sail according to an embodiment of the present invention and a method for storing and deploying the side sail.

An embodiment and a reference ship according to the present invention are provided with a main engine and a propulsion device driven by the main engine, and as an auxiliary propulsion, for example, a hard sail arranged on a deck 2 as shown in FIG. A side sail 10 (hereinafter, referred to as a side sail) 10 is formed.

First, a method for storing and deploying a ship and a side sail according to the embodiment will be described. As shown in FIGS. 1 to 6, the side sail 10 used in the ship 1 of this embodiment is provided with a mast (post) 11 vertically on the deck 2, and in a substantially horizontal direction from the mast 11 to the side. A plurality of extending sail girders (yards) 12 are provided in parallel to each other, and a sail member 13 is movably fitted between the upper and lower sail girders 12 as shown in FIG. In the configuration of FIG. 5, the roller 12 a is disposed in a space 12 s provided in the sail beam 12 to hold the expansion portion 14 at the upper end portion of the sail member 13. As a result, the sail member 13 can move in the direction in which the sail beam 12 extends with the sail beam 12 as a guide.

  Further, by moving the outermost sail member 13a to the mast 11 side, the sail member 13 is stored in the mast 11 (or in the vicinity of the mast 11), and the outermost sail member 13a is moved to the opposite side of the mast 11. Thus, the sail member 13 is configured to be deployed.

  As shown in FIG. 6, this structure is provided with a step 13 c at the back end of one sail member 13 and a convex portion 13 d at the front end of the other sail member 13. When the sail member 13 is moved in the direction of the arrow for deployment, the step 13c of one sail member 13 and the convex portion 13d of the other sail member 13 are caused by a change in the relative position of the sail members 13, 13. The lower sail member 13 is engaged with each other, and can be deployed by pulling the upper (left side) sail member 13.

  In addition, when moving in the opposite direction for contraction or storage, the engagement between the step 13c and the convex portion 13d is released, and the sail members 13, 13 overlap each other. And when the substantially whole sail members 13 and 13 will be in the state which overlaps, the same engaging part (not shown) formed in another part engaged, and sail members 13 and 13 overlapped each other. Configured to move together in a state.

  According to this configuration, the mast 11 and the sail girder 12 remain on the deck 2 during storage, and the field of view is obstructed compared to before the side sail 10 is provided, but the mast 11 and the sail girder 12 are relatively simple. Easy to install on existing ships.

Next, a reference ship and a method for storing and deploying a side sail will be described. As shown in FIGS. 7 to 12, the side sail 10A used for this reference vessel is configured by arranging the sail member 13A in the vertical direction, and moving the uppermost sail member 13Aa downward, The sail member 13A is configured to be unfolded by storing the sail member 13A on the lowermost sail member 13Ab and moving the uppermost sail member 13Aa upward.

  In the case of the sail members 13A, 13Aa, and 13Ab shown in FIGS. 10 to 12, when the side sail 10A is contracted or retracted, when the uppermost sail member 13Aa is moved downward, the upper sail members 13A and 13Aa are sequentially moved. Since the bending member 13b provided on the back side of the lower end of the bending member 13b pushes down the bending member 13b of the lower sail members 13A and 13Ab, the bending member 13b sequentially moves downward.

  Further, to deploy the horizontal sail 10A, when the uppermost sail member 13Aa is moved upward, an engaging portion (not shown) provided on the lower end front side of the upper sail member 13A, 13Aa and the lower sail member 13A, An engaging portion (not shown) provided on the back side of the upper end of 13Ab performs substantially the same engagement as the engaging portion shown in FIG. 6, and the lower sail member 13A is lifted and sequentially moved upward.

  According to this configuration, when the side sail 10A is stored, the mast 11 and the sail beam 12 do not remain on the deck 2 as in the case of the side sail 10 of the first embodiment, but overlap the lowermost sail member 13Ab. Therefore, the field of view of this size is hindered.

Next, a method for storing and deploying another vessel and a side sail for reference will be described. As shown in FIGS. 13 to 14, the side sail 10B used for another reference ship is configured by arranging the sail member 13B in a fan shape around the center 14B, and the tip side is farthest from the storage member 13Bb. By rotating and moving the sail member 13Ba to the storage member 13Bb side, the sail member 13B is stored on top of the storage member 13Bb, and the sail member 13Ba whose tip side is farthest from the storage member 13Bb is rotated to the opposite side to the storage member 13Bb. By doing so, the sail member 13B is configured to be deployed. In this case, it is a rotational movement, but it is possible to easily reduce the sail by providing an engagement portion substantially the same as the sail member 13A of the side sail 10A used for the reference ship on the tip side of the sail members 13B, 13Ba, 13Bb. It can be stored and expanded.

  According to this configuration, when the side sail 10 is stored, the mast 11 and the sail beam 12 do not remain on the deck 2, but overlap with the lowermost sail member 13Ab, so that the field of view of this size is hindered.

  Further, regarding the arrangement of the side sail 10 on the deck 2, as shown in FIG. 1, the side sail 10 (or 10A, 10B) is arranged so as to be in a straight line from the monitoring position of the bridge 3. As far as you can go, you should minimize the area where visibility from the bridge is obstructed. Also, the front field of view is made as wide as possible by reducing the height as it goes forward.

  According to the above-described method for storing and deploying the ship 1 and the side sail, the main sail, the propulsion device driven by the main engine, and the side sails 10, 10A, 10B formed by the hard sails arranged on the deck 2 are provided. The equipped ship 1 can be contracted and retracted when the side sails 10, 10A, 10B are not required, ensuring visibility in the congested sea area, and maneuvering under anchoring winds, anchoring, and the performance of the landing berth It is possible to improve and reduce the aerodynamic resistance under the headwind.

  According to the ship equipped with a horizontal sail formed by the hard sail of the present invention and the method for storing and deploying the horizontal sail, the main engine, the propulsion device driven by the main engine, and the hard sail arranged on the deck are formed. In a ship equipped with a horizontal sail, it can be contracted and stored when no sail is required, ensuring visibility in congested waters, and improving performance with respect to maneuvering, anchoring, and landing piers under strong winds. Since it is possible to reduce the aerodynamic resistance under the head wind, it can be used for many ships including existing ships.
