Problems solved by technology

[0010] (d) Due to the high cost of machining, there is a problem of high manufacturing costs
[0011] (e) In addition, since the machines that can perform such machining are limited to specific machines, the factories that can manufacture are limited, and there are problems of increased transportation costs and long construction periods due to waiting for processing

Embodiment approach 1

[0094] [Embodiment 1: Ship with conduit for ships]

[0095] Fig. 1 is a partial side view showing an outline of a ship with a ship duct according to Embodiment 1 of the present invention. In FIG. 1 , a ship 1 with a ship duct has a hull 2 ​​, a propeller 3 protruding from the stern of the hull 2 ​​(on the right side in the figure), and a ship duct 4 provided on the stern of the hull 2 ​​.

[0096] The conduit 4 for ships is arranged on both sides of the hull 2, and is roughly trapezoidal (in the figure, the line segment connecting position A-position B-position D-position C) in a side view (the same direction as the observation ship side) respectively. Formed), in the front view (the same direction as the observation of the stern) is a roughly semicircle (not shown). In addition, the ship duct 4 provided on the starboard side and the ship duct 4 provided on the port side are plane-symmetrical to each other, in the range near the bridge (upper side in the figure) and in the ra...

Embodiment approach 2

[0103] [Embodiment 2: Catheter for ships - one]

[0104] FIG. 2 is a side view showing the outline of a ship duct according to Embodiment 2 of the present invention. In FIG. 2 , the ship duct 4 is a ship installed on the starboard side of the ship 1 with the ship duct shown in FIG. 1 . Use a catheter.

[0105] The ship duct 4 has a duct outer plate 10 as a part of a cone whose diameter is larger on the bow side than on the stern side, and whose upper side (corresponding to the bridge side or water surface side) is longer than the lower side (corresponding to the ship bottom side or sea bottom side). Inside the duct outer panel 10 , the cylindrical stern side inner panel 20 whose upper side is longer than the lower side, and the bow side inner panel 30 housed in the duct outer panel 10 .

[0106] In addition, the stern side edge 12 of the duct outer panel 10 (the arc connecting position C and position D) is connected to the stern side edge 22 of the stern side inner panel 20 (...

Embodiment approach 3

[0113] [Embodiment 3: Catheters for Ships - Part 2]

[0114] Fig. 4 is a side view showing an outline of a vessel conduit according to Embodiment 3 of the present invention. In FIG. 3 , the ship duct 5 is provided on a pipe body 40 along the bow side edge 11 of the duct outer plate 10 , and the bow side edge 31 of the bow side inner plate 30 is joined to the pipe body 40 . That is, it differs from the marine conduit 4 shown in Embodiment 2 ( FIG. 2 ) in that it has a pipe body 40 , and is the same as the marine conduit 4 in other respects. In addition, the same code|symbol is attached|subjected to the same part as Embodiment 2, and some description is abbreviate|omitted.

[0115] Therefore, the ship duct 5 exhibits the effect of the ship duct 4, and the joint of the duct outer plate 10 and the bow side inner plate 30 becomes easy, and the large curvature of the bow side edge portion 31 of the bow side inner plate 30 can be omitted. processing, so the manufacture of the bow s...

Abstract

The present invention provides a marine duct that can be easily manufactured while maintaining performance as an energy-saving device, a manufacturing method of the marine duct, and a ship with a marine duct provided with the marine duct. The ship duct (4) has a duct outer plate (10) which is a part of a cone whose bow side is larger in diameter than the stern side and whose upper side is longer than the lower side, and is housed in the duct outer plate (10) with the upper side longer than the lower side. A cylindrical stern inner panel (20) with long sides, and a bow inner panel (30) accommodated inside the duct outer panel (10). The stern side edge (12) of the duct outer plate (10) is connected with the stern side edge (22) of the stern side inner plate (20), and the bow side edge (11) of the duct outer plate (10) and the bow side inner The bow side edge (31) of the plate (30) is connected, and the stern side edge (32) of the bow side inner panel (30) is connected to the bow side edge (21) of the stern side inner panel (20).

Description

technical field [0001] The present invention relates to a ship duct provided at the stern of a ship, a method of manufacturing the ship duct, and a ship equipped with a ship duct provided with the ship duct. Background technique [0002] In a ship, a device that recovers energy lost when the hull moves forward and obtains an energy-saving effect As a type of energy-saving equipment, there is a cylindrical device (called a duct or nozzle) installed in front of the propeller ( For example, refer to Patent Documents 1 and 2). [0003] [Patent Document 1] Utility Model Registration Publication No. 2555130 (page 2, Figure 1) [0004] [Patent Document 2] Japanese Unexamined Patent Publication No. 11-278383 (pages 2 to 3, FIG. 2 ) [0005] However, in the utility model disclosed in Patent Document 1, although an annular nozzle of a predetermined shape (same as a ship duct, hereinafter referred to as a "ship duct") can be provided between the stern of the hull and the propeller, t...
