Description

[Detailed Description of the Invention] The present invention relates to an improvement of a land-powered light buoy used as a marking device for a seaplane landing channel.

A description will be given below of an application of the present invention to a landing channel marking device.

Signs used for seaplane landing lights, etc., require a large amount of light power so that they can be clearly identified from a considerable distance and can be identified from airplanes even on cloudy, rainy or foggy days. Therefore, shore power supply is an essential requirement.

However, with conventional floating light buoys, if you try to supply shore power, the power transmission cable will get entangled in the mooring line and be damaged, and the distance from the set position will be large. Marking devices had not yet been realized.

In addition to this method, when attempting to install indicator lights on the landing channel, there is a method of planting a large number of indicator light columns on the seabed along the landing channel, but this method is extremely difficult to construct and costs a lot. Not only was there a huge amount of water, but it also had serious drawbacks, such as the inability to easily change the waterway.

In this invention, the upper part of the column protrudes above the water, and the column with an underwater buoyant body in the middle is pulled into and moored to a sinker on the seabed, and a landing channel light is installed on the top of the column, and along the support mechanism of these lights. , an easy-to-install landing channel marking device that is equipped with a land power cable for lights that runs from the seabed to the light equipment, so that the light hardly leaves its predetermined position and can easily output the necessary large amount of light power. This provides a light buoy suitable for supplying shore electricity.

The contents of the present invention will be explained in detail below according to embodiments shown in the drawings.

FIG. 1 is a front view of a landing channel marking device which is an embodiment of the present invention. As shown in the figure, this marking device includes an underwater buoyant body 2 in the middle of a column 1 . At the lower end of 1',
It is pulled into and moored to a sinker 4 on the seabed by a relatively short main mooring line 3.

The column 1 is always maintained in an almost upright state by the buoyancy of the buoyancy body 2 located in the water.

Further, a landing channel light 5 consisting of a high-intensity marker light is provided at the top of the column 1', and a power supply cable 6 for this landing channel light 5 is provided at the column 1', the buoyant body 2, and the column 1''. It is mounted along a guide rod 6' for cable lashing, and is further connected to a submarine cable 8 for supplying shore electricity via a cable connector 7.

At the top of the column 1', in addition to the above-mentioned landing channel light 5, an upright pole 9 is installed, and on the top of this upright pole 9 is an illumination light 10, and below it is a rotatable windsock 11.
is equipped, and furthermore, an aviation obstacle light 12 is provided at the tip of the upright pole 9. 13 and 14 are a radar reflector and an anemometer provided below the windsock 11. These devices can notify airplanes of wind direction even at night, function as radar wave markers, and allow wind speed observations. An eye plate 15 is attached to both sides of the lower part of the column 1'', and an auxiliary mooring line 16 is stretched between the eye plate 15 and the sinker 4.The eye plate 15 and the auxiliary mooring line 16 are attached to the landing channel. The eye plate 15 and the auxiliary mooring rope 16 prevent the column 1 from rotating, and the landing channel light 5 is thereby set. It is possible to always point in a fixed direction (landing channel direction) and perform a stable function as a landing channel marker.

FIG. 2 shows an example in which an elastic auxiliary mooring line is stretched across the eye plate 15 and the sinker 4.

That is, FIG. 2a shows the elastic body 17 in a state where the elastic body 17 made of rubber or the like is interposed between the connecting links.
Fig. 2b shows an auxiliary mooring line 16' made of a chain molded for the required length by a method, and Fig. 2b shows an elastic cord 16' made of rubber or the like spanning several chain links.
7' is stretched and no tension is applied to the auxiliary mooring rope 16'', the chain within the range where the elastic cord 17' is stretched has slack, or the elastic cord 1
This figure shows the auxiliary mooring line 16'' configured to surround the outer periphery of the mooring line 7' (see Fig. 2 b'). Elastic body 17 or 1 interposed between the links
7' is compressed or tensioned and the mooring line 16' or 16''
It is becoming more and more energizing. (In the case of the auxiliary mooring line 16'' shown in Figure 2b, when a tensile force is applied,
Until then, the elastic body 1 is relaxed as shown in Figure 2 b'.
The chain surrounding the outer periphery of the mooring line 7' is expanded straight, and the elastic body 17' surrounds the outer periphery of the chain as shown in FIG. 2b'', thereby biasing the mooring line 16''. ) Therefore, if such an auxiliary mooring line is used, even if the sinker 4 is installed in an inclined state depending on the condition of the seabed, the degree of inclination will be within the elastic strain range set for the auxiliary mooring line. If within,
Due to the biasing force applied to the auxiliary mooring cable, a force is acting to pull the column 1 that is about to tilt, and even if rotational force is applied around the vertical axis of the column, the column will rotate against this force. Therefore, the direction of the landing channel light 5 is maintained stably.

According to the present invention, the power for the lights can be sufficiently supplied from land, so the light power of the lights should be of the necessary magnitude, taking into account changes in the environment and the distance the light reaches. I can do it. Also, column 1
By setting the buoyancy of the underwater buoyant body 2 to an appropriate level, it is possible to strongly maintain an upright position underwater.
Therefore, the landing channel light 5 almost never leaves its predetermined setting position, and furthermore, the eye plate 15 and the auxiliary mooring cable 16 prevent the column 1 from rotating, so the light provides a stable directional indication. hold in condition.

This device is pulled in and moored to a sinker 4 on the seabed, so once it is installed, it can be used as a fixed position marker at that location, but the mooring line can be unmoored and the sinker can be moved to another location. Since it can be moored to the seabed or moved by the sinker, it can be installed with much easier construction than a type of pillar that is driven into the seabed, and the construction cost can also be lowered.
