  Hereinafter, a ship navigation regulation structure according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a schematic diagram illustrating a state in which a ship navigation regulation structure according to an embodiment of the present invention is installed on the surface of a target water area. The ship navigation regulation structure 1 partitions the target water area into an inner water area 2 and an outer water area 3. Here, the inner water area 2 is, for example, a water area where a landfill work is performed or a water area in the vicinity thereof, and is a water area where the navigation of the ship 5 is prohibited or restricted. The ship navigation restriction structure 1 is configured by connecting a plurality of ship navigation restriction lines 10 in a line.

  As shown in FIG. 1, a light buoy 4 is connected to the ship navigation regulation structure 1 at a predetermined interval. The light buoy 4 includes an illumination device (not shown) that lights a lamp for a sign. A crew member of a vessel 5 navigating the outer water area 3 is provided with a vessel navigation regulation line 10 as a vessel navigation regulation structure 1 between the light buoys 4 arranged by checking the lighting from the lighting device at night. Can be recognized. Thereby, the crew member of ship 5 can recognize that the other side than ship navigation regulation line 10 is a water area (inner water area 2) where navigation of ship 5 is restricted.

  FIG. 2 is an enlarged plan view showing a part of the vessel navigation regulation line 10 constituting the vessel navigation regulation structure according to the embodiment of the present invention. Moreover, FIG. 3 is the figure which showed the ship navigation control line which comprises the ship navigation control structure which concerns on embodiment of this invention, (a) is sectional drawing which showed the whole, (b) is in (a) It is sectional drawing shown by arrow bb of.

  As shown in FIG. 2, the vessel navigation regulation line 10 includes a plurality of floats 20, a float interval holding member 30 arranged to hold a distance between the floats 20, a float 20 and a float interval holding member 30. The outer appearance of the rope 40 inserted through the end and the end spacer 50 that restricts the movement of the float 20 at the left and right ends in the figure in the left-right direction is schematically configured.

  The float 20 has a substantially spherical shape, and as shown in FIG. 3, for example, an outer body 21 made of high-density polyethylene and an inner body 22 made of foamed polystyrene and covered with the outer skin body 21. It consists of and. As described above, the outer skin 21 of the float 20 is made of high-density polyethylene, so that the float 20 is provided with appropriate strength and durability. Deterioration can be prevented. Further, by configuring the inner body 22 of the float 20 from foamed polystyrene, an appropriate buoyancy can be applied to the ship navigation regulation line 10 installed on the water surface. As shown in FIG. 3, a rope insertion hole 20 a through which the rope 40 is inserted is formed in the approximate center of the float 20. The rope insertion hole 20 a is a slightly larger hole than the diameter of the rope 40. Thereby, the float 20 inserted through the rope 40 can rotate around the rope 40.

  As shown in FIG. 3, the float spacing member 30 includes four resin hoses 31, 33, 34, 35 having different diameters, a hose band 32, and two buffer spacers 36. The float spacing member 30 is passed through the rope 40 and disposed between the adjacent floats 20. The float spacing member 30 includes a first resin hose 31 wound around the hose 40 in a state of being cut along the length direction, and a hose band 32 for fastening and fixing the first resin hose 31 to the rope 40. And have. The first resin hose 31 is, for example, a vinyl chloride resin hose having an inner diameter of 50 mm (nominal diameter 50). On the other hand, the hose band 32 is made of stainless steel, for example. The first resin hose 31 is fastened to the rope 40 by tightening the screws (not shown) of the three hose bands 32 arranged at intervals.

  The rope insertion hole 20a formed in the float 20 is formed in such a size that the hose band 32 that fastens the first resin hose 31 to the rope 40 cannot pass through. As a result, even if the rope 40 is cut at any point, the first resin hose 31 attached to the rope 40 by the hose band 32 is caught in the rope insertion hole 20a. It can prevent that 30 falls out from the cutting | disconnection location of the rope 40, and falls apart.

  The second resin hose 33 is, for example, a vinyl chloride resin hose having an inner diameter of 75 mm (nominal diameter 75), and the first resin hose 31 is fastened to the rope 40 as shown in FIGS. 3 (a) and 3 (b). Surround the hose band 32. The third resin hose 34 is, for example, a vinyl chloride resin hose having an inner diameter of 125 mm (nominal diameter 125), and surrounds the second resin hose 33 as shown in FIGS. 3 (a) and 3 (b).

  The buffer spacer 36 is configured by laminating three rubber plates 36a formed in a disk shape, and a rope insertion hole 36b for inserting the rope 40 is formed at the center thereof. As shown in FIG. 3A, a first resin hose 31, a second resin hose 33, and a third resin hose 34, which are elastic bodies, are interposed between the two buffer spacers 36.

  The fourth resin hose 35 is, for example, a vinyl chloride resin hose having an inner diameter of 200 mm (nominal diameter 200), and as shown in FIGS. 3 (a) and 3 (b), each component of the above-described float spacing member 30. And the outermost part of the float spacing member 30 is formed. The fourth resin hose 35 is longer than the first resin hose 31, the second resin hose 33, and the third resin hose 34. Accordingly, the buffer spacer 36 disposed in contact with the end portions of the first resin hose 31, the second resin hose 33, and the third resin hose 34 is positioned on the inner side than the end portion of the fourth resin hose 35. The fourth resin hose 35 is housed in the fourth resin hose 35. In this embodiment, a soft vinyl chloride resin hose is used as the first resin hose 31, the second resin hose 33, the third resin hose 34, and the fourth resin hose 35 described above. In addition, it is possible to use various types of hoses and other pipe materials that are easy to cut and that have moderate flexibility and weather resistance.

  The rope 40 is, for example, a rope made of polyparaphenylene terephthalamide (PPTA) fiber. Both ends of the rope 40 are subjected to ice price processing to form a ring portion 40a. As will be described later, the ring portion 40a is used to connect the ship navigation regulation line 10 to be long.

  The end spacer 50 is formed by laminating three rubber plates 50a formed in a disk shape, like the buffer spacer 36, and a rope insertion hole 50b for inserting the rope 40 at the center thereof. Is formed. The end spacer 50 is arranged so as to be in contact with the float 20 arranged on the outermost side of the vessel navigation restriction line 10 from the end side of the vessel navigation restriction line 10. That is, the two end spacers 50 are arranged so as to sandwich both ends of the float 20 and the float spacing member 30 that are alternately arranged in a line.

  Further, on the outer side of the end spacer 50, a fifth resin hose 60 cut along the length direction and wound around the rope 40, and a hose band 61 for fastening the fifth resin hose 60 to the rope 40, have. The fifth resin hose 60 is, for example, a vinyl chloride resin hose having an inner diameter of 50 mm (nominal diameter 50). On the other hand, the hose band 61 is made of stainless steel, for example. The fifth resin hose 60 is fastened to the rope 40 by fastening the screws (not shown) of the three hose bands 61 arranged at intervals. The size of the rope insertion hole 50b opened in the end spacer 50 is such that the fifth resin hose 60 and the hose band 61 tightened to the rope 40 with the fifth resin hose 60 cannot pass therethrough. Thereby, the movement in the left-right direction of the end spacers 50 provided on both sides of the ship navigation restriction line 10 is restricted.

  Further, the ship navigation regulation line 10 has a branch rope 71 branched from the rope 40. The branch rope 71 is made of, for example, polyparaphenylene terephthalamide (PPTA) fiber, similarly to the rope 40. At one end of the branch rope 71, an ice price process is performed to form a ring portion 71a. The float spacing member 30 is formed with a notch 30b through which the branch rope 71 is inserted.

  Next, the manufacturing method of the ship navigation control line 10 is demonstrated. FIG. 4 is a cross-sectional view showing the manufacturing process of the ship navigation control line constituting the ship navigation control structure according to the embodiment of the present invention in the order of steps ((a) to (b)). FIG. 5 is a cross-sectional view illustrating the manufacturing process of the marine vessel navigation control structure according to the embodiment of the present invention in the order of steps ((a) to (b)) subsequent to FIG. 4.

  First, as shown in FIG. 4A, a rope 40 having a ring portion 40a formed at one end is prepared. Then, the fifth resin hose 60 cut in the length direction is wound around the ring 40 a of the rope 40 and fastened with the three hose bands 61. Subsequently, as shown in FIG. 4A, the end spacer 50, the float 20, the buffer spacer 36, the first resin hose 31, and the hose band 32 are arranged in this order from left to right in the drawing. Pass through the hose 40. Then, as shown in FIG. 4B, the rope 40 and the first resin hose 31 are fastened with the three hose bands 32. At this time, the float 20 is compressed from the left and right by the buffer spacer 36 and the end spacer 50. This is realized by restricting the movement of the buffer spacer 36 in the left direction in the figure by tightening the first resin hose 31 with the hose band 32 while the buffer spacer 36 is pressed to the right in the figure. As a result, the state in which the buffer spacer 36 presses the float 20 to the right is maintained.

  Subsequently, as shown in FIG. 4B, the second resin hose 33, the third resin hose 34, the buffer spacer 36, and the fourth resin hose 35 are arranged in this order from left to right in the drawing. Pass through the hose 40. As a result, the float spacing member 30 is formed on the left side of the float 20 as shown in FIG.

  Subsequently, as shown in FIG. 5A, the float 20, the buffer spacer 36, the first resin hose 31, and the three hose bands 32 are connected to the hose 40 in this order from left to right in the drawing. Pass through. Then, as shown in FIG. 5B, the first resin hose 31 is fastened to the rope 40 using the three hose bands 32. At this time, the left float 20 in FIG. 5B is sandwiched between the left and right buffer spacers 36 and is compressed in the axial direction. This is because the pressed state of the buffer spacer 36 is maintained by tightening the three hose bands 32 while the buffer spacer 36 is pressed to the right in the drawing.

  In this way, the float 20 and the float spacing member 30 are alternately passed through the rope 40 and fixed. Finally, the other end of the hose 40 is subjected to ice price processing to form a ring portion 40a. Thereby, the ship navigation regulation line 10 is formed.

  Thus, when manufacturing the ship navigation control line 10, the operation | work of attaching to the rope 40, pressing each component to one direction (for example, right direction in the figure) is repeated. Thereby, each float 20 presses the adjacent float space | interval holding | maintenance material 30 and the edge part spacer 50, and is hold | maintained in the contact | adhered state. The float spacing member 30 and the end spacer 50 are made of an elastic material. Therefore, when manufacturing the marine vessel navigation restriction line 10, when each component is pressed in one direction, the float gap retaining member 30 and the end spacer 50 accumulate compression energy. In the state where the float spacing member 30 and the end spacer 50 have accumulated compression energy, they are attached to the rope 40 while restricting the movement in the left-right direction in the drawing. Therefore, each float 20 presses the adjacent float space | interval holding | maintenance material 30 and the edge part spacer 50, and can hold | maintain the state which the mutual member contact | abutted without the clearance gap reliably. Thereby, a hand cannot be put between the float 20 and the float spacing member 30 and between the float 20 and the end spacer 50. For this reason, it is difficult for a crew member of the vessel 5 to lift the vessel navigation restriction line 10, and it is difficult to avoid or remove the vessel navigation restriction structure 1 and allow the vessel 5 to enter the inner water area.

  Further, the fourth resin hose 35 is made longer than the first resin hose 31, the second resin hose 33, and the third resin hose 34, so that the buffer spacer 36 is located inside the end of the fourth resin hose 35. It is arranged. As a result, the outermost fourth resin hose 35 of the float spacing member 30 is strongly pressed against and abuts the float 20, so that it is possible to reliably eliminate a gap into which a human hand enters.

  Moreover, the float space | interval holding | maintenance material 30 can be manufactured using the resin hose and hose band which are marketed. Therefore, the manufacturing cost can be suppressed and the manufacturing can be performed in a short period of time.

  Moreover, since the rope insertion hole 20 a formed in the float 20 is a slightly larger hole than the diameter of the rope 40, the float 20 inserted through the rope 40 rotates around the rope 40. Therefore, resistance due to water flow can be reduced and the rope can be prevented from being twisted. Moreover, since a person cannot get on the float 20, it can be made difficult to intentionally remove the ship navigation restriction structure 1.

  In addition, the ship navigation control line 10 which comprises the ship navigation control structure 1 is set to the length of 30 m or less, for example, in consideration of workability. Therefore, when the range which should be divided into the outer side water area 3 and the inner side water area 2 is large, the ship navigation control line 10 is connected on-site, and it installs on the water surface as a long thing. FIG. 6 is a plan view showing two types of connection methods (a) and (b)) of the vessel navigation regulation line constituting the vessel navigation regulation structure according to the embodiment of the present invention.

  As shown to Fig.6 (a), the 1st ship navigation control line 10a and the 2nd ship navigation control line 10b are arrange | positioned in series so that the edge part of each rope 40 may be faced | matched. Then, the shackle 70 is passed through the ring portion 40a of the first vessel navigation restriction line 10a and the ring portion 40a of the second vessel navigation restriction line 10b, and the first vessel navigation restriction line 10a and the second vessel navigation restriction line. 10b is connected. In addition, as shown to Fig.6 (a), the float 20 is not installed in the location which connected the 1st ship navigation control line 10a and the 2nd ship navigation control line 10b in series using the shackle 70. FIG. A section 80 exists. The third ship navigation regulation line 10c is installed in parallel with the section 80 where the float 20 is not installed.

  The third vessel navigation restriction line 10c is shorter than the first vessel navigation restriction line 10a and the like, but the main configuration is the same. The third vessel navigation restriction line 10c is abutted against a branch rope 71 having one end extending from the first vessel navigation restriction line 10a. Then, the shackle 70 is passed through the ring portion 71a formed on the branch rope 71 of the first vessel navigation restriction line 10a and the ring portion 40a formed on the rope 40 of the third vessel navigation restriction line 10c. The 1 ship navigation regulation line 10a and the 3rd ship navigation regulation line 10c are connected. Further, the third vessel navigation restriction line 10c is abutted against a branch rope 71 whose other end extends from the second vessel navigation restriction line 10b. Then, the shackle 70 is passed through the ring portion 71a formed on the branch rope 71 of the second vessel navigation restriction line 10b and the ring portion 40a formed on the rope 40 of the third vessel navigation restriction line 10c. The two vessel navigation regulation line 10b and the third vessel navigation regulation line 10c are connected.

  Thus, the ship navigation control structure 1 is extended by providing the third ship navigation control line 10c so as to be parallel to the connecting portion between the first ship navigation control line 10a and the second ship navigation control line 10b. A float 20 can be provided over the entire direction. Accordingly, it is possible to prevent the vessel 5 (FIG. 1) from entering from the section 80 where the float 20a is not installed, which is a connecting portion between the first vessel navigation restriction line 10a and the second vessel navigation restriction line 10b. it can.

  As another connection method of the vessel navigation restriction line 10, as shown in FIG. 6B, a part of the fourth vessel navigation restriction line 10d and a part of the fourth vessel navigation restriction line 10e are wrapped. Link. That is, the shackle 70 is passed through the ring portion 40a formed at one end of the fourth vessel navigation restriction line 10d and the ring portion 71a formed on the branch rope 71 extending from the fifth vessel navigation restriction line 10e. Further, the shackle 70 is passed through a ring part 71a formed on the branch rope 71 extending from the fourth ship navigation restriction line 10d and a ring part 40a formed at one end of the fifth ship navigation restriction line 10e. Thereby, the 4th vessel navigation regulation line 10d and the 5th vessel navigation regulation line 10e are connected in the state where each other was wrapped.

  Thus, the 4th ship navigation regulation line 10d and the 5th ship prevention buoy 10e are connected in the state where a part of each other was wrapped, so that the entire area in the direction in which the ship navigation regulation structure 1 extends is floated. 20 can be provided. Thus, the entry of the ship 5 can be reliably prevented by eliminating the section where the float 20 is not installed.

  Next, a marine vessel navigation restriction structure according to another embodiment of the present invention will be described. FIG. 7 is a view showing a vessel navigation restriction line constituting a vessel navigation restriction structure according to another embodiment of the present invention, in which (a) is a plan view and (b) is a sectional view. In addition, in the ship navigation control line 110 which concerns on this embodiment, it has many components similar to the ship navigation control line 10 concerning said embodiment. Therefore, in the following description, different components will be mainly described, and similar components will be denoted by the same reference numerals.

  As shown in FIGS. 7 (a) and 7 (b), the float spacing member constituting the ship navigation regulation line 110 has a float spacing retaining block 130 and an end face plate 136. The float spacing block 130 is made of a substantially cylindrical rubber block that is an elastic material. As shown in FIG. 7B, a rope insertion hole 130 a for inserting the rope 40 is formed at the center of the float interval holding block 130, and each float 20 is inserted in the rope 40. It is arranged between. In addition, on the left and right end faces of the float interval holding block 130 in the drawing, an accommodating portion 130b that is a concave portion for accommodating the resin hose 131 and the hose band 132 is formed. Further, the predetermined float interval holding block 130 is formed with a notch 130c for allowing the branch rope 71 branched from the rope 40 to pass therethrough.

  The end face plate 136 that is in contact with both sides of the float 20 is formed from a single rubber plate formed in a disc shape, and a rope insertion hole 136a for inserting the rope 40 is formed at the center thereof. Yes.

  In the ship navigation regulation line 110, the float 20 and the float interval holding block 130 are illustrated by the resin hose 132 fastened to the rope 40 by the hose band 131 and the resin hose 160 fastened to the rope 40 by the hose band 161. Movement in the middle / left / right direction is restricted. As described above, the resin hose 131 and the hose band 132 are accommodated in the accommodating portion 130b formed in the float interval holding block 130, and the end face plate 136 is disposed so as to cover the accommodating portion 130b. In addition, as a method of connecting the ship navigation regulation line 110, the method similar to the method demonstrated in the above-mentioned embodiment is employable.

  Also in the ship navigation regulation line 110 according to the present embodiment, the float 20, the end face plate 136, and the float interval holding block 130 are passed through the rope 40. Then, in a state where these components are pressed in one direction (for example, right direction in the drawing), the operation of tightening the hose band 131 and the hose band 161 and attaching the components to the rope 40 is repeated. Therefore, each float 20 presses the adjacent float space | interval holding | maintenance block 130 and the end surface plate 136 like the ship navigation control structure 1 which concerns on embodiment mentioned above, and is hold | maintained in the closely_contact | adhered state. Moreover, the float space | interval holding | maintenance block 130 and the end surface plate 136 which were distribute | arranged between each of the float 20 are comprised from the rubber | gum which is an elastic material. Therefore, each float 20 can press the adjacent float space | interval holding | maintenance block 130 and the end surface plate 136, and can hold | maintain the state which contact | adhered reliably.

  The present invention is not limited to the above embodiment, and various modifications and applications are possible. In the said embodiment, although the outer skin body which comprises the outer surface of a float demonstrated that it was comprised from the high density polyethylene, you may comprise an outer skin body from a rubber body, for example.
