Abstract

<P>PROBLEM TO BE SOLVED: To provide a buoy used for mooring a vessel in fishery harbors, harbors, and other facilities that emits light even without using a power source or a mechanical device. <P>SOLUTION: A light storage material is mixed in a skin material or a skin coating material of the mooring buoy 1 to make the mooring buoy 1 luminous. The light storage type luminous mooring buoy 1 is extremely inexpensive with reduced failure and breakage because unlike conventional buoys, electric and mechanical facilities are not loaded thereon. Because the light storage material emits light over a long period of time by irradiation of sunlight, it is continuously luminous even when sunlight is not received. When the light storage material securing brightness of 3 mcd/m<SP>2</SP>12 hours after a 5-minute irradiation at 20,000 lux is used, the buoy 1 is emits light over an extremely long period of time, so that the standard of using the buoy 1 as a safety indication is sufficiently cleared, and safety of marine vessels can be enhanced. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

  The present invention relates to a buoy used when a ship is moored at a fishing port, a port, or other facilities, and relates to a buoy that emits light without using a power source or a mechanical device.

  At fishing ports / ports and other facilities, as shown in FIGS. 1 and 2, a mooring buoy 1 is installed to moor the ship S and is usually installed in the water with a chain or other mooring line 2 The mooring anchor 3 is connected. The ship S is generally connected to the mooring buoy 1 and the revetment A by separate mooring lines 4, 5, 6.

  Since the ordinary mooring buoy 1 does not shine, there are many dangers when the ship returns to the port at night and touches the mooring place because the surroundings are dark. In particular, fishing boats have many opportunities to sail at night, and the light for night sailing is only forward and the irradiation range is narrow. Therefore, the danger when contacting a mooring place is extremely high.

  In order to prevent this, conventionally, a flashing device having a power source has been attached to the mooring buoy.

  However, since this type of device is very expensive, few people use a mooring buoy equipped with this device. In addition, since the apparatus is an electrical / mechanical facility, it is likely to break down or break, and the mooring buoy does not emit light and often is not used. Until the repair is completed, the safety of the ship cannot be ensured.

  An object of the present invention is to eliminate such conventional drawbacks, and a phosphorescent material is mixed in the outer shell material or outer coating material of the mooring buoy so that the mooring buoy can emit light. . Since it is not equipped with electrical / mechanical equipment as in the prior art, it is extremely inexpensive and there is little failure or damage. Since the phosphorescent material emits light for a long time by irradiation with sunlight, it continuously emits light even if the sunlight disappears.

As the phosphorescent material, it is preferable to use a material capable of securing a luminance of 3 mcd / m ² after 12 hours of irradiation with 20000 Lux for 5 minutes. By using such a phosphorescent material, since it continues to emit light for an extremely long time, the criteria for use as a safety sign can be sufficiently cleared, and the safety of the ship can be improved.

  According to the first aspect of the present invention, since it is not equipped with electrical / mechanical equipment, it is very inexpensive and there is little failure or damage. Since the phosphorescent material emits light for a long time by irradiation with sunlight, it continuously emits light even if the sunlight disappears.

  According to the second aspect of the present invention, since it continues to emit light for an extremely long time, it is possible to sufficiently satisfy the standard for use as a safety sign and to improve the safety of the ship.

  Preferred embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a cross-sectional view showing an example of a phosphorescent mooring buoy according to the present invention installed in the vicinity of a seawall. FIG. 2 is a plan view of a part of FIG.

  As can be seen from both figures, a mooring buoy 1 that can be suspended on the surface of the water to moor the ship S is installed in the vicinity of the revetment A and is usually installed in the underwater area with a chain or other mooring cable 2 A mooring anchor 3 is connected. The ship S is connected to the mooring buoy 1 and the revetment A by separate mooring lines 4, 5, 6.

In the mooring buoy 1, a phosphorescent material is mixed in the outer skin material or the outer skin coating material so that the mooring buoy 1 can emit light. As shown in FIG. 3, the mooring buoy 1 can be made to emit light by forming the phosphorescent portion 1a on the outer peripheral surface of the mooring buoy 1 and positioning the phosphorescent portion 1a on the water surface. Since the phosphorescent material emits light for a long time by irradiation with sunlight, it continuously emits light even if the sunlight disappears. Since this phosphorescent mooring buoy is not equipped with electrical or mechanical equipment, it is extremely inexpensive and has little failure or damage.

In forming the phosphorescent portion 1a, for example, the phosphorescent material may be mixed in the outer skin material made of urethane resin covering the outside of the inner foamed polystyrene, or the phosphorescent material is mixed in the outer skin coating material. Also good. In any case, the mooring buoy 1 can emit light.
The case where the phosphorescent material is mixed in the outer coating material means that the phosphorescent material is mixed into the resin (paint), and the mooring buoy 1 can be caused to emit light by spraying the resin (paint) on the outer shell. The workability is superior to the case where a phosphorescent material is mixed in the outer skin material. Increasing the mixing ratio of the phosphorescent material to the resin (paint) can increase the luminance of light emission. However, if the mixing ratio is excessively high, the viscosity becomes so high that the coating work may be hindered. Increasing the number of sprays can increase the luminance of light emission.

As the phosphorescent material, it is preferable to use a material that continues to emit light for as long as possible. In particular, a material that can ensure a luminance (average luminance) of 3 mcd / m ² after 12 hours of irradiation with 20000 Lux for 5 minutes is used. Is the best. By using such a phosphorescent material, since it continues to emit light for an extremely long time, it is possible to sufficiently satisfy the standard for use as a safety sign and to improve the safety of the ship S.

  As described above, the mooring buoy 1 illustrated here is of a type that emits light for a long time when irradiated with sunlight. Therefore, even if there is no sunlight, the mooring buoy 1 continues to emit light, and the ship S touches the mooring place. Can avoid danger. That is, mooring of the ship S can be performed safely, and it can contribute to reduction of the construction cost of a facility. Moreover, in the mooring facility in the place where the navigation of the ship S is intense, it contributes to ensuring the safety of the other ships S. Furthermore, since it is not equipped with electrical / mechanical equipment, it is extremely inexpensive and has little failure or damage.

  To moor the mooring buoy 1, the ship S, and the mooring anchor 3 with mooring lines 2, 4, 5, for example, as shown in FIG. 3, a shackle is attached to one connecting ring 1 b provided at the bottom of the mooring buoy 1. Via the ends of the mooring lines 2, 4, 5.

In FIG. 1, HWL represents a high water level, and LWL represents a low water level. The mooring status of the ship S to the revetment A at the high water level is indicated by a solid line, and the ship S ′ to the revetment A at the low water level is illustrated. The mooring status is indicated by a two-dot chain line. 1 is a mooring rebar for the mooring anchor 3, and the lower end of the mooring line 2 is connected to the mooring rebar 3a.

  The phosphorescent mooring buoy according to the present invention can be widely used in fishing ports, harbor protection, docks and the like.

It is sectional drawing which shows an example at the time of installing the phosphorescence mooring buoy by this invention in the bank protection vicinity. It is a partial top view of FIG. It is an enlarged side view which shows an example in the case of mooring a mooring buoy, a ship, and a mooring anchor by a mooring measure.
