[Detailed Description of the Invention] Light buoys that indicate navigational aids or construction areas, etc. use a limited power supply to spread the light far and maximize the marking effect, so the light is focused into horizontal light by a lens. The angle of spread with respect to the horizontal is very small. Therefore, when a light buoy is shaken by waves, if the shake exceeds the horizontal spread angle of the light, the beacon light cannot be seen at all from a navigating vessel. However, when a general light buoy encounters a slight wave, its swing angle quickly exceeds the spread angle of the beacon light. Therefore, a light buoy with a universally supported gimbal mechanism has been devised, with a weight installed at the bottom of the light so that the light always remains horizontal, that is, the light always remains vertical even when the light buoy is tilted by waves. . However, light buoys, especially floating light buoys, are often shaken by waves, and since the light buoy is located at the top of the turret, which is most affected by wave agitation, the buoy sways violently and it is difficult to place a weight under the light buoy. Even if it was installed and supported by a gimbal mechanism, it would not always be vertical and would sway, which meant that no light fixture with a gimbal mechanism had yet been put into practical use. The present invention relates to a lamp horizontal holding device that maintains the lamp vertically even when the buoy oscillates, so that horizontal light can always be obtained. In supporting the lamp on the turret or the top of the target, the present invention supports the lamp in a tiltable manner, and also supports the lamp in a parallel holder, which is attached to the buoy at a position apart from the lamp. By connecting to a vertical or horizontal indicator, even if the buoy is shaken by waves, the light always maintains its vertical position and maintains horizontal light, allowing it to fully perform its function as a beacon light. It has been made possible to do so. The following will explain the embodiments shown in the drawings. Figure 1 shows an example of a light buoy moored to a sinker by a mooring line, which is used as a navigation aid. In this type of light buoy, a light fixture 3 is installed at the top of a turret 2 that stands on the top surface of the buoyant body 1, and a mooring ring 4 provided at the center of the bottom surface of the buoyant body 1 is connected to a mooring line (not shown). It is connected to a sinker (not shown) on the ocean floor by a sinker (not shown). In the present invention, the light fixture 3 is a general standard type light fixture, as shown in FIGS. 4 and 5, and when it is installed, a bracket as shown in FIGS. 6A, B, and C is used. It is fixed to the support plate 5' of No. 5 with bolts 6. Support rods 5'' are erected on both sides of the support plate 5', and the support rods 5'' are connected to a shaft 8 attached to the support ring 7 to maintain the height of the center of gravity of the lamp 3 and the bracket 5 in one unit. It is pivotably mounted at the bottom. Further, the support ring 7 is rotatably pivoted in a direction perpendicular to the shaft 8 by a shaft 10 mounted on a support 9 erected at the top of the turret 2. With this configuration, the lamp 3 is universally supported at the top of the turret 2 at the center of gravity including the receiving fitting 5 so as to be freely tiltable. On the other hand, a vertical indicator 11 as shown in FIGS. 2 and 3 is provided inside the buoyant body 1 almost near the center of gravity of the light buoy. This vertical indicator 11 includes a rod 13 with a weight 12 attached to its lower end, a support part 14 that universally supports the rod 13 in a tiltable manner, for example, by two sets of axes perpendicular to each other, and a displacement of the rod 13. and a rod upper part 13' that transmits the angle to the parallel holder 15 . The parallel holder 15 is the second
4, a hydraulic cylinder is used as the displacement angle transmission mechanism. That is, a protruding rod 16 is provided at the center of the lower surface of the support plate 5' of the lamp 3, and the rod 16 and the top of the tower 2 are connected by four hydraulic cylinders 17 arranged in two mutually orthogonal directions. has been done. Further, a cross-shaped piston rod attachment piece 19 is provided on the rod upper part 13' of the vertical indicator 11 , and a hydraulic cylinder 18 arranged in two mutually perpendicular directions is provided between the attachment piece 19 and the buoyant body 1. Concatenated. Hydraulic cylinders 17 and 18 are protruding rods 1
6 and the upper part 13' of the rod can be angularly displaced by tilting. The upper and lower pairs of hydraulic cylinders are fluid-tightly and flexibly connected through conduits 20. In this case, the length of the upper part 13' of the rod is equal to the height from the piston rod mounting center position of the protruding rod 16 on the support plate 5' of the lamp 3 to the center position of the shaft 8, and the specifications of the hydraulic cylinders 17 and 18 are the same. If the diameters of the conduits 20 are selected to be equal and the relative positions are symmetrical, the parallel holder 15 will exhibit its parallel function. That is, when the light buoy is tilted by waves, the vertical indicator 11 attempts to maintain the vertical posture of the rod 13 by the action of the weight 12 at the lower end of the rod 13, which is supported so as to be tiltable. Along with this, the movement of the upper part 13' of the rod is controlled by the hydraulic cylinder 18.
is transmitted, and the hydraulic cylinder 17 works in the opposite direction by the same working length as this working length, so that the center line of the lamp 3 becomes parallel to the rod 13 and tries to maintain a vertical posture. Reference numeral 21 denotes an annular stopper which is installed on the buoyant body 1 in a ring shape around the weight 12 at appropriate intervals. By configuring as above, now,
When the light buoy tilts due to waves, the vertical indicator 1
1 moves vertically, but the parallel holder 1
The movement angle is transmitted to the lamp 3 via 5,
It works to raise the light fixture 3 from the inclination of the light buoy and keep it in a vertical position. Therefore, the horizontal light of the lamp always tries to maintain a horizontal state regardless of the tilting of the lamp buoy. FIG. 3 shows an example in which the parallel holder 15 is constructed of cables and pulleys in two directions, left and right, respectively, and the lamp 3
The center of the spherical bottom surface of the support plate 5' and the vertical indicator
The center of the spherical top surface of the eleven rod upper parts 13' having similar shapes and dimensions is connected by an endless cable 22. The cable 22 is stretched so as to rotate smoothly by a pulley 23 mounted at a suitable position within the light buoy, and when the rod 13 is tilted, the holder 5 of the lamp 3 is moved by the amount of rotation of the upper portion 13' of the rod. Rotate to keep the lamp 3 in a vertical position. In this example, the vertical indicator 11 is installed inside the buoyant body 1, but it may also be stored inside a house provided on the deck of the buoyant body 1, or inside a box provided at the bottom of the turret. Furthermore, in the case of a light buoy in the form of a spar buoy, it may be installed at an appropriate location within the specimen. Further, the vertical indicator 11 may be a horizontal indicator that transmits horizontal angular displacement. For the parallel holding device 15 , in addition to a hydraulic cylinder type or a type using cables and pulleys, a link mechanism or an electric type can also be used. In the present invention, a vertical indicator including a lamp 3 and a weight is provided.
The light fixture 3 is supported on the top of the turret 2 so as to be freely tiltable, and the vertical indicator 11 , which is equipped with a weight to control it, is placed at the most of the swinging of the light buoy. Since the light fixture 3 is installed near the center of gravity, both are supported by a tiltable gimbal mechanism, etc., and both are connected by a parallel holder 15 . Since the light itself is lightweight and supported by a gimbal mechanism at the height of the center of gravity, the light itself will not tilt even when the light buoy oscillates.
Therefore, there is no risk of the lamp rotating and being damaged due to violent shaking such as when a ship collides, unlike conventional lamps with a leveling mechanism directly connected to a weight. In addition, since the vertical indicator is placed near the center of gravity, where the amount of fluctuation and displacement is least within the light buoy, it is easy to maintain the vertical position, and it can fully perform its function as a vertical indicator. Furthermore, since the swing angle is limited by the stopper, the light fixture will not tilt any further, and therefore there is no risk of damage even if the light buoy is shaken violently. As described above, the present invention allows the light to be safely maintained vertically even when the light buoy is violently shaken by waves, etc., so that the light can be maintained horizontally and fulfill its mission as a beacon light. . The present invention does not require a separate power source unlike the gyro system, and the posture is automatically controlled by its own mechanism, so there is no waste and it is economical. In this example, we explained a floating light buoy, but
Of course, it can also be applied to cylindrical light buoys that are moored directly to the bottom of the water.
