JPS6133385A - Thick disc type buoy - Google Patents

Abstract

PURPOSE:To make operations so easy in time of maintenance and adjustment, by setting up a projectable resistance plate at a reciprocal symmetric position in a side direction of a circular body of a thick disc type buoy available in a stationary meteorological observation or the like, while giving a direction inclination to a rock against waves and tides. CONSTITUTION:In case of a thick disc type buoy available in stationary meteorological observations, wave observations, etc., each of resistance plates 3a and 3b being constituted free of projection to the lower part by a rope or the like is set up a reciprocal symmetrical position in a side direction 2b of a circular body part 2 formed beneath a mast part 1. At the time of maintenance and adjustment, each of these resistance plates 3a and 3b is projected outward whereby positioning is performable to a direction 4 of tides and waves, thus the operation is easily performable.

。Conventional configurations and their problems In general, thick disk-shaped buoys have good recovery performance and wave tracking ability, and have been used as unmanned observation stations for stationary weather observation and wave observation. FIG. 1 shows a conventional thick disc-shaped buoy. The configuration of this conventional example will be explained below with reference to FIG. 1. In FIG. 1, reference numeral 1 denotes a mast section, which is equipped with sensors and equipment necessary for communication, and is fixed near the center of the hull section 2. The hull section 2 can be divided into an inclined bottom section 2a and a main body section 2b. W and L represent horizontal planes.

ブイの特徴である良好な波浪追従性を生む要因となって
いる。Next, the operation of the above conventional example will be explained. In FIG. 1, the ballast of the buoy has been adjusted so that the water line is located at the oblique bottom 2a. This is because when the water level rises (wave crest), the buoyancy increases as the water level rises due to its tapered part.9 This is a characteristic of thick disc-shaped buoys. This is a factor that produces a certain good wave tracking ability.

また、ブイは上面より見ると円形であり海洋での複雑な
波浪状態に対応できる。Additionally, the buoy has a circular shape when viewed from above, allowing it to cope with complex wave conditions in the ocean.

しかしながら、上記従来例においては、ブイが良好な波

ブイが水平面内において、３６Ｑ０方向自由に動揺し、
しかも周期３秒程度のゆっくシとしたものであシ、作業
者は、いわゆる船酔いの状態になシやすかった。However, in the above conventional example, since the buoy has good wave followability, it is difficult to perform maintenance and adjustment at sea.
The buoy swings freely in the 36Q0 direction in the horizontal plane,
Moreover, it was slow and had a cycle of about 3 seconds, making it easy for workers to get seasick.

It is provided so as to arbitrarily protrude downward into the water from the main body portion 2b. A similar resistance plate portion 3b is also provided on the opposite side of the buoy.

のいずれかになる。Next, the operation of the above embodiment will be explained. In Fig. 2, when the resistance plate parts 3a and 3b are made to protrude into the water during maintenance adjustment, the buoy is maintained so that the resistance plate parts are in the left and right positions against the tide or waves from the flow direction 4. drooping Therefore, the buoy no longer rotates freely,
The movement becomes directional and becomes either pitching or rolling.

きる。By the way, the specific structure of the resistance plate parts 3a and 3b is explained in the third section.
As shown in FIG. In FIG. 3, the resistance plate 6 held by the rope 5 by the stopper 12 is attached to the main body 2b.
The guide 7 and the gear 8 provided on the resistance plate 6 are engaged to move the body part 2b downward (underwater). According to this configuration, the resistance plate 6 can be arbitrarily moved between a state of being integrated with the main body part 2b and a state of protruding into the water simply by operating the rope 5 on the deck part. In the configuration shown in FIG. 4, the resistance plate 9 is attached to a hinge 10 provided on the main body, and can be integrated into the deck 11 of the main body or protruded into the water as in FIG. 3. The resistance plate 9 can be moved arbitrarily.

Therefore, the workability is good, and there is no need to make any special improvements to the equipment.
