Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a storage structure for a drogue (resistive body) used for a buoy for suspending an ocean sensor or the like.

[0002]

2. Description of the Related Art A device is known in which an ocean sensor is suspended from a buoy floating on the sea surface via a cable to a predetermined depth, and various ocean information at the suspended depth is collected. As one of them, there is a balloon provided with a dragg (drag) for obtaining the buoyancy of the buoy.

FIG. 6 is a perspective view of a buoy having such a drogue after being dropped into the ocean. In the figure, 1 is the buoy body,
2 is a balloon, 3 is a drogue, and this drogue 3 has a band-shaped sail portion 3a whose one end is joined to the peripheral surface of the balloon 2 by welding or the like, and a sail portion 3a which is located at a certain distance from the joining portion. It is composed of a frame 3b having a spring attached and a frame 3c having a spring attached to the other end which is the free end of the sail portion 3a. Here, the frames 3b and 3c are the shapes of the sail portion 3. And a weight (not shown) is provided on the frame 3c.

A marine sensor (not shown) is hung at a predetermined depth on the buoy body 1 via a cable (not shown), and a flexible antenna is housed in the balloon 2 so that the ocean An electronic device or the like for sending the information collected by the sensor to the ground station via the antenna is housed in the buoy body 1. In this configuration, when the drogue 2 is stretched below the sea level, the sail portion 3a hangs down due to the weight of the frame 3c when the tidal current is slow, so that it acts as a large resistance to the tidal current, and when the tidal current is fast, the sail 3 Since the portion 3a is lifted in the horizontal direction, the resistance against the tidal current becomes small.

Therefore, the velocity of the buoy body 1 caused by the tidal current is stabilized by the action of the drogue 2. As described above, the drogue 2 stabilizes the speed at which the buoy body 1 is flown, but conventionally, the drogue 2 is housed together with the buoy body 1 and the ocean sensor in a cylindrical container (not shown). After being dropped on and landing on water, the balloon 2 is pulled out from the container and expanded by the buoy body 1 which is separated from the container by the expansion.

[0006]

However, in the above-mentioned conventional technique, since the drogue is structured to be pulled out from the inside of the container by utilizing the detaching force of the buoy body from the container after the container is flooded, It is necessary to store it in the container so that it is on the lower side of the buoy body, so the drogue that is joined at one end to the balloon provided at the top of the buoy body has a part of its sail part on the outer peripheral surface of the buoy body. Since it is stored in the container with a slight gap between it and the inner peripheral surface of the container, when the buoy body is separated from the container,
There is a problem that a part of the sail portion, that is, a portion sandwiched between the outer peripheral surface of the buoy body and the inner peripheral surface of the container is rubbed and damaged by the buoy body.

[0007]

In order to solve this problem, the present invention is directed to a belt-shaped sail portion in which one end of the sail portion is joined to the peripheral surface of a balloon that gives buoyancy to a buoy body for suspending an ocean sensor or the like. In the storage structure of the drogue, which is composed of a frame having a spring property provided at least at a free end of the sail portion, is stored in a container together with the buoy body, the marine sensor, etc., and is dropped from the container after being dropped into the sea, The balloon is folded, the drogue is folded and overlapped on the balloon, and a cap having a shape in which the upper surface of the tubular body is closed and divided into two is covered from above the drogue,
The drogue is housed in the container together with the balloon and the buoy body.

According to the present invention having such a structure, when the container is dropped into the ocean, the balloon is inflated and the cap is pushed out of the container.
At the same time when it is split into two parts and thrown away, the drogue that was folded on the balloon is thrown from the balloon. Then, with the buoyancy of the balloon detaching the buoy body, the drogue extends below the sea level.
