Description

発明の詳細な説明Detailed Description of the Invention

産業上の利用分野Industrial application fields

この発明は、海中等に長時間沈潜させた後、浮上した装置のアンテナの防護カバーを自動的に剥脱させる装置に関するものである。  The present invention relates to a device for automatically peeling off a protective cover of an antenna of a device that has floated after being submerged in the sea for a long time.

従来から、海中等に沈潜させて種々の観測データを収集する装置、例えば地震計、流速・流向計、塩分濃度計等が使用されている。これらの装置は海中において蓄積したデータを回収するために時限装置で浮上させられる。このとき、大海を浮遊する装置は、その位置を通報するために、GPS受信機等の電波測位機と測位データを通報するための無線通信装置が使用される。これらには必然的にそれぞれ特有のアンテナが必要になり、各装置の上部に防水処置を施したアンテナケース内に設置されている。  Conventionally, a device that collects various observation data by submerging in the sea or the like, for example, a seismometer, a flow velocity / current meter, a salinity concentration meter, and the like has been used. These devices are levitated by timed devices to collect data accumulated in the sea. At this time, in order to report the position of a device floating in the ocean, a radio communication device such as a GPS receiver and a positioning communication data is used. Each of these devices inevitably requires a unique antenna, and is installed in an antenna case that is waterproofed on the top of each device.

発明が解決しようとする課題Problems to be solved by the invention

海中に長時間沈潜した物体には、貝類、藻類等が短時間で付着蔓延してその物体を覆い尽くすことはよく知られており、上記アンテナケースについても例外ではなく、これによってアンテナ効率は著しく低下する。
本発明は、このような問題を解決するために為されたものであって、浮上後のアンテナが本来の性能を発揮できるようにすることを目的とする。
It is well known that shellfish, algae, etc. adhere to and spread over objects that have been submerged in the sea for a long time, and the antenna case is no exception. descend.
The present invention has been made to solve such a problem, and an object of the present invention is to enable an antenna after flying to exhibit its original performance.

課題を解決するための手段Means for solving the problem

1または複数のアンテナを収納する不導体のアンテナケースの外側に、密着するアンテナカバーを被せて海中に沈潜し、アンテナカバーに貝類、藻類等を付着させることによって、内部のアンテナケースの表面を保護し、装置の浮上後、内部に設けた圧搾気体ボンベを開封し、気体の圧力によってアンテナカバーを剥脱させる。  Protect the surface of the internal antenna case by covering the outside of the non-conducting antenna case that houses one or more antennas with a close antenna cover and sinking into the sea, and attaching shellfish, algae, etc. to the antenna cover Then, after the apparatus is lifted, the compressed gas cylinder provided inside is opened, and the antenna cover is peeled off by the pressure of the gas.

作用Action

アンテナを設置したアンテナケースが剥き出しのまま海中に長時間沈潜しているときに発生するであろう貝類、藻類等が、アンテナケースに被せたアンテナカバーに付着し、浮上後貝類、藻類等の付着したアンテナカバーが剥脱排除する。この結果、貝類、藻類等の付着していない表面を有するアンテナケースが露出するのでケース内に設置されたアンテナは本来の性能を発揮することができる。  Shells, algae, etc. that may occur when the antenna case with the antenna is exposed and have been submerged in the sea for a long time adhere to the antenna cover placed on the antenna case. The removed antenna cover is removed. As a result, the antenna case having a surface to which shellfish, algae, and the like are not attached is exposed, so that the antenna installed in the case can exhibit its original performance.

以下、本発明によるアンテナ防護装置の1実施例について、図面を参照して説明する。
図1は、本発明によるアンテナ防護装置の構造を示す図である。1はアンテナカバー、2はアンテナケース、3はアンテナベース、4はアンテナである。アンテナカバー1は、アンテナベース3に取り付けたアンテナケース2に密着して被さり、さらに下部にパッキングを挿入して完全な気密性を保ってある。
Hereinafter, an embodiment of an antenna protection device according to the present invention will be described with reference to the drawings.
FIG. 1 is a diagram showing the structure of an antenna protection device according to the present invention. 1 is an antenna cover, 2 is an antenna case, 3 is an antenna base, and 4 is an antenna. The antenna cover 1 is covered in close contact with the antenna case 2 attached to the antenna base 3, and further, packing is inserted in the lower part to maintain complete airtightness.

5はガスボンベ、6はボンベケース、7はソレノイド、8はソレノイドケース、9は撃針である。
ガスボンベ5は、アンテナベース3に高い気密性を持って取り付けられたボンベケース6に収納されており、その下端部が撃針9を受ける位置に固定されている。
5 is a gas cylinder, 6 is a cylinder case, 7 is a solenoid, 8 is a solenoid case, and 9 is a firing pin.
The gas cylinder 5 is housed in a cylinder case 6 attached to the antenna base 3 with high airtightness, and a lower end portion thereof is fixed at a position for receiving the firing needle 9.

ソレノイド7は、ボンベケース6に高い気密性を持って取り付けられたソレノイドケース8に収納されており、その上端部に取り付けた撃針9がガスボンベ5の下端部を叩く位置に固定されている。  The solenoid 7 is housed in a solenoid case 8 attached to the cylinder case 6 with high airtightness, and the firing needle 9 attached to the upper end of the solenoid 7 is fixed to a position where the lower end of the gas cylinder 5 is hit.

10はソレノイド駆動回路、11は圧力スイッチ、12は電池、13は送信装置、14は外筐である。
送信装置13は、アンテナベース3に取り付けられており、ソレノイド駆動回路10、電池12、及び圧力スイッチ11をその底部に取り付けた外筐14は、上記アンテナベース3の下部に取り付けた部品を覆うように水密性を保ってアンテナベースに取り付けてある。
10 is a solenoid drive circuit, 11 is a pressure switch, 12 is a battery, 13 is a transmitter, and 14 is an outer casing.
The transmitter 13 is attached to the antenna base 3, and the outer casing 14 having the solenoid drive circuit 10, the battery 12, and the pressure switch 11 attached to the bottom thereof covers the parts attached to the lower part of the antenna base 3. It is attached to the antenna base with watertightness.

次に本装置の動作を説明する。
海中に沈潜させて動作する種々の観測装置がタイマーによる意識的、または不慮の事故による無意識的に浮上したとき、外筐14にかかる水圧が所定の値より低下するから圧力スイッチ11が動作して、ソレノイド駆動回路10を起動してソレノイド7を所定時間駆動する。これによって、ソレノイド7のプランジャーに取り付けられた撃針9がガスボンベ5の先端部を突き破り、所定時間後ソレノイド7が断となり、撃針9が引き戻されてガスの放出孔ができる。
Next, the operation of this apparatus will be described.
When various observation devices that operate while submerged in the sea rise consciously by a timer or unintentionally due to an accident, the pressure switch 11 operates because the water pressure applied to the outer casing 14 drops below a predetermined value. Then, the solenoid drive circuit 10 is activated to drive the solenoid 7 for a predetermined time. As a result, the firing needle 9 attached to the plunger of the solenoid 7 breaks through the tip of the gas cylinder 5, the solenoid 7 is disconnected after a predetermined time, and the firing needle 9 is pulled back to form a gas discharge hole.

放出孔から放出されるガスはソレノイドケース8、ガスボンベケース6、アンテナケース2内に充満し、遂にはアンテナケース2の頂部に設けた細孔から漏れ出し、上記細孔の周りに施した溝を介してアンテナカバーを持ち上げる。
アンテナカバー1とアンテナケース2との間は、擦り合わせを蜜にしてあり、さらにパッキングを嵌合して気密性を高めてあるので上部に充満したガスはアンテナカバー1をアンテナケース2の湾曲部まで押し上げ、遂には離脱させる。
The gas released from the discharge hole is filled in the solenoid case 8, the gas cylinder case 6, and the antenna case 2, and finally leaks out from the pores provided at the top of the antenna case 2, and a groove formed around the pores. Lift the antenna cover through.
The antenna cover 1 and the antenna case 2 are rubbed together, and the packing is further fitted to improve the airtightness, so that the gas filled in the upper portion of the antenna cover 1 and the antenna case 2 are bent. Push it up and finally let it leave.

発明の効果The invention's effect

本発明のアンテナ防護装置によれば、剥脱可能なアンテナカバーを使用することによって、沈潜時に貝類、藻類の付着したアンテナカバーを浮上と同時に剥脱することができるので、海中に沈潜して動作する観測装置等の浮上後の通信機能が、アンテナカバーの内部に保護されていたアンテナによって有効に動作する。この結果、海上に浮遊する浮上した観測装置等の回収が容易となる。According to the antenna protection device of the present invention, by using a removable antenna cover, the antenna cover to which shellfish and algae are attached can be removed at the time of sinking, so that the observation that operates by sinking in the sea. The communication function after the ascent of the device or the like is effectively operated by the antenna protected inside the antenna cover. As a result, it is easy to collect the floating observation device floating on the sea.
