Description

[Detailed Description of the Invention] The present invention is a buoy that floats on water! - This invention relates to a buoy with a directional light device equipped with a directional light device for illuminating in a predetermined direction.

Directional lighting devices such as navigational marking lights for vessels installed at port entrances and waters with many reefs, etc., or intrusion amount 1 It is installed on a fixed pole, etc.

It is very convenient to install a directional lamp on a fixed pole I- installed on land (or on the bottom of the water) in order to fix the directional lamp in a fixed direction, but the pole land-
Construction work to install 3G poles at the bottom of the water is often difficult (in particular, work to install poles from the bottom of the water was often difficult).

If directional lights are installed at TL markers, it will be much easier to install directional lights in the necessary water area,
The buoy is water! Since it is floating at -1, some degree of rotational movement is 111? Therefore, in the past, it was actually considered impossible to irradiate a specific direction by supporting a directional device that irradiates in the j-direction on the 1-L mark.

The present invention addresses this problem, which has hitherto been invisible. This relates to a system in which a directional lamp is installed at a y-marker, and the directional lamp is mounted on a turntable that is rotatably supported in a horizontal plane and is driven by a turntable. A direction detector with a magnetic compass is installed separately, and the output of this direction detector drives a turntable rotation device, so that the directional lamp always points in a fixed direction. As a result,
Installing a directional light at 11-marker 1-, which was considered impossible in the past, has become an nT function, and it can be installed in any water area, and the installation work is extremely easy, quick, and inexpensive. The present invention provides a buoy with a directional light device that can be constructed and is extremely easy to relocate.

In the following, the contents will be explained in detail based on the embodiments shown in the attached drawings.

FIG. 1 is an external view showing an example of a buoy with a directional light device according to the present invention. In this example, the directional light device includes, for example,
The right half shows white light, and the left half shows red light, using navigational marking lights that emit different lights and colors depending on the direction. @2 Figure (a) is a detailed view of part A in Figure 1, Figure 2 (b) is a part \ IL view of Figure 2 (a), Figure 2 (C)
Figure 3 shows a block diagram of the turntable drive system.

The buoy with directional light shown in the example in Figure 1 is moored to a sinker (4) on the seabed by a mooring ring (2) and a mooring line (3) provided at the center of the F side of the lug body (1). In the water-L floating type buoy that has come to be used, a turntable (6) is rotatably supported on the top of a turret (5) erected on the upper surface of the L-shaped body (1). A directional lamp (7) is attached to the -F side of the table, and a buoyant body (1) made of a non-magnetic material such as aluminum alloy or F'RP is attached.
It consists of a direction detector (8) installed inside.

(The direction detector (8) is preferably provided at a position closest to the center of gravity of the buoy. In this example, it is provided inside the buoyant body, but depending on the structure of the buoy, it may be provided on the top of the buoyant body. ) The direction detector (8) is connected to the magnetic compass (9) on the support plate of the magnetic compass, surrounding the support shaft (g) of the magnetic compass, and at a predetermined angle on the circumference of the diameter of the magnetic needle of the magnetic compass. It is composed of an appropriate number of Hall element sensors (10) arranged in a ring shape at intervals. (See Figure 2 (, )) Macnet compass (9
) and the Hall element sensor (10), the output of the Hall element sensor (10) is zero when the buoy is installed in a specified body of water and the indicator light (7) is irradiated in the specified direction. It is set to be

Historically, when a buoy moves simultaneously under the influence of ocean currents, winds, and waves,
In order to maintain a constant direction of the magnetic compass (9), the Hall element sensors (10) arranged in an annular manner rotate by a rotation angle of 1, and as a result, some Hall element sensors (10) are connected to the magnet. When it comes under the influence of the magnetic field of the compass (9), the Hall element sensor that comes under the influence of the magnetic field sequentially transmits pulses so that the pulse corresponding to the rotation angle is extracted as the output of the direction detector (8). provided.

Further, the polarity of the output of the direction detector (8) is set to be opposite when the buoy rotates clockwise and counterclockwise.

The output of the Hall element sensor (10), that is, the direction detector■
As shown in Fig. 3, the output of is increased I+] '5 (I
I), a turntable rotation device (14) consisting of a control device (12) and a stepping motor (13) that rotates by a predetermined angle in response to an output pulse from an azimuth detector. ) is connected to the input end of the

The stepping motor (13) is connected to the turntable support plate (
5') (see Fig. 2 (aXb)), and the gear (15) fitted to the motor holder is mounted on the annular rack (16) provided on the underside of the turntable (6). Constructed to interlock.

Therefore, when the stepping motor (13) receives the pulse and rotates by a predetermined angle, the turntable (6)
Therefore, the indicator light (7) also rotates by a predetermined angle in a predetermined direction.

The direction of rotation of the turntable (6) driven by this turntable rotation device (14) is determined by an azimuth detector (charcoal and turntable rotation device By setting the relationship between Regardless of whether it is rotated in the left or right direction, it can be immediately rotated back to its original normal position, and the irradiation direction of the indicator moon (7) can be directed to the predetermined setting force 11r.

In the following, the orientation detector (8), turntable method, etc. are not particularly illustrated, but the feeding means will be a flexible cable or a slip ring, etc. , an intensifier, a control device, etc., are housed in the buoyant body in this example.
Further, in this embodiment, a Hall element sensor is used as the direction detector, but a rotary encoder method using an optical method, a differential method using electromagnetic coupling, or the like may be used.

The example in Figure 4 shows a turret (
A horizontal holder (17) is attached to the top of 5), a turntable (6) is rotatably supported by this Suito holder, and a floodlight (7) is attached to one side of the turntable. (See Figure 5) An example of a buoy with a directional light device is shown in Figure 71.

In this example, l'Y
When the target rotates and the floodlight (7) moves from its normal azimuth orientation, the angle of rotation is detected by the azimuth detector (
8) detects and outputs a pulse, drives the turntable rotation device (14), and returns the turntable (6) and therefore the floodlight (7') to its original normal orientation regardless of the rotation of the buoy. Rotate it back in the direction.

The lf mark with a directional external light device equipped with a horizontal holder as in this example is suitable for a light device or a water area where horizontal illumination is particularly required.

Although the present embodiments have all been described in the case of a one-tube type buoy, it is of course applicable to a retractable mooring type spanner one-tube buoy as shown in the example in FIG.

Since the present invention has the above-described configuration, even if the buoy rotates due to the influence of ocean currents, wind waves, etc., the directional light device will always illuminate a predetermined □ direction. It can function satisfactorily as a navigation guide for ships in waters where there is a lot of water, or as a danger area indicator indicating areas where entry is prohibited.

Furthermore, as shown in the example in Fig. 4, if the turntable with the lamp attached is supported by the water holder 11,
Even in a water area with large waves and severe agitation, the horizontal illumination of the directional lamp can be maintained at all times.

According to the present invention, there is no need to install a ball or the like on land or the bottom of the water as in the past, and it can be installed extremely easily and quickly in a desired body of water. Not only can the construction cost be much lower, but it is also extremely easy to relocate.
