【発明の詳細な説明】
（イ） 産業上の利用分野
水中に沈設した物体の位置を船上の魚群探知機（魚探）
を使用して容易に探知できる装置に関する。[Detailed description of the invention] (a) Industrial application field Fish finder on board a ship to locate objects submerged in water
It relates to a device that can be easily detected using.
（ロ）従来の技術
かに籠、たこ壺、底網等、海底に沈設したものは魚探で
は探知できず、今までボンデン（位置表示用ブイ）を係
留したり、陸上の標示物を見透して沈設位置を推定（い
わゆる「山たて」）を行ってきた。(b) Conventional technology Crab cages, octopus pots, bottom nets, and other items sunk on the seabed cannot be detected with fish finders. We have used this method to estimate the location of the deposit (so-called ``mountain position'').
（ハ） 発明が解決しようとする問題点しかし、ボンデ
ンは時化で切れたり、流されたすするし、捕獲物が盗難
に会う恐れもあり、やまたでも沖に出るとむつかしくな
る。(c) Problems that the invention aims to solve However, it becomes difficult to venture out to sea, as there is a risk that bondage will break due to the turbulence or be washed away, and that the captured items may be stolen.
また沈船、魚礁等対象物が大きい場合は、魚探を使って
捜索できそうに考えられるが、海底の起伏が大きい処で
はむつかしい。In addition, if the target is large, such as a sunken ship or a fish reef, it may be possible to search for it using a fish finder, but this is difficult in areas with large undulations on the sea floor.
に） 問題点を解決するための手段
本発明は、中空球体を水面下に引き込み、水中に沈設し
た被表示物に係留索により係止し、魚探により容易に検
知できるようにした装置である。2) Means for Solving the Problems The present invention is a device in which a hollow sphere is pulled under the water surface and is anchored to a display object submerged in the water using a mooring rope so that it can be easily detected by a fish finder.

It was installed with. Figure 2 a shows the underwater position of one hollow sphere, Figure 2 shows two hollow spheres, and Figure 2 C shows three hollow spheres (1) attached in series with the mooring rope (5). It is a display device.
（ホ） 作用
水中の中空球体は、魚探から発射された超音波を外皮外
面および外皮内面より反射し、魚探の映像面に鮮明に写
し出される。その反射強度は魚群の反射強度の数百倍あ
り、魚群のエコーと判然と識別できる。(E) The hollow sphere in the working water reflects the ultrasonic waves emitted from the fish finder from the outer surface of the skin and the inner surface of the skin, and is clearly imaged on the image plane of the fish finder. Its reflection intensity is hundreds of times higher than that of a school of fish, and can be clearly distinguished from the echoes of a school of fish.
中空球体１ケでも魚探の影像面に海底面のエコー像（６
）上に鮮明な突出像（７）を映し出すが、２ケ、６ケと
直列に連結した装置では、映像はさらに縦長く明瞭とな
る。これを第６図に示し、左より順に中空球体が１ケ、
２ケ、６ケのものの影像を示す。Even with just one hollow sphere, an echo image of the seafloor surface (6
), but if two or six devices are connected in series, the image will be longer and clearer. This is shown in Figure 6, where from the left there is one hollow sphere,
Images of 2 and 6 objects are shown.
このように水中の対象物に係止する中空球体の係止個数
を定めて沈設すれば、個々の対象物の沈設位置を明瞭に
魚探で容易に検知できる。If the number of hollow spheres to be locked to underwater objects is determined and placed in this way, the position of each object can be clearly and easily detected with a fish finder.
（へ）実施例
また適宜個数の中空球体を直列に係止した装置を用いれ

水流の状態も魚探で知ることができる。(F) Embodiment If a device in which an appropriate number of hollow spheres are connected in series is used, the state of the object being tilted diagonally by the water flow will be displayed, and the state of the water flow in the water can also be known with a fish finder.

されたりして位置が判らなくなる恐れもない。(G) Effects of the Invention As described above, if a crab cage, octopus pot, bottom net, etc. equipped with the underwater position display device of the present invention is submerged in water, its position can be found extremely easily with a fish finder. . Also, unlike Bonden, there is nothing that floats on or near the water surface,
It will not obstruct ship traffic, and there is no risk that the device will be cut off or washed away by the waves and lose its location.
