Description

本発明は、深海等の水中での地震観測、水温等の各種の観測に用いられる水中観測機器に関し、特に、ユニット化された筐体部の連鎖構造を採用した耐圧容器を用いた水中観測機器及び水中観測システムに関する。
The present invention relates to underwater observation equipment used for various types of observations such as seismic observation in the deep sea, water temperature, etc., and in particular, an underwater observation equipment using a pressure vessel that employs a united casing structure. And an underwater observation system.

従来、水中観測特に、深海観測に用いられる機器では、水圧下による圧壊を防止するため、十分な耐圧強度が要求され、その強度を備えた耐圧容器が筐体に用いられる。耐圧容器は耐圧強度が大きくなる程に重量が増大する傾向にある。 Conventionally, equipment used for underwater observation, particularly deep sea observation, is required to have sufficient pressure strength in order to prevent collapse due to water pressure, and a pressure vessel having that strength is used for the casing. The pressure vessel tends to increase in weight as the pressure strength increases.

このような観測機器に関し、特許文献１には、観測のためのケーブルを収納しつつ、容器内部に配置される内部ユニットの気密性を実現する構造として、円柱容器の内部に測定のための内部ユニットが配置され、円柱容器は第１及び第２のカバーによって密閉され、その外部に嵌合されたジョイントリングの内部に配置されたジョイントチャンバカバーによって密閉されていることが開示されている。
特開２００２−２５７６３４公報（要約、図１等） With regard to such an observation device, Patent Document 1 discloses that a structure for realizing airtightness of an internal unit disposed inside a container while accommodating a cable for observation is provided inside the cylindrical container for measurement. It is disclosed that the unit is disposed and the cylindrical container is sealed by the first and second covers and sealed by the joint chamber cover disposed inside the joint ring fitted to the outside thereof.
JP 2002-257634 A (summary, FIG. 1 etc.)

深海観測用の観測機器３００は例えば、図１４に示すように、円筒胴部３０２の両開口部に蓋部３０４、３０６を取り付け、円筒胴部３０２と蓋部３０４、３０６との間にはそれぞれＯリング３０８を介在させて密閉させている。円筒胴部３０２の内部に形成された収納空間部３１０には複数の機器３１２、３１４、３１６が設置され、各機器３１２、３１４、３１６は接続電線３１８、３２０で接続され、機器３１２、３１４、３１６に対する給電や機器間のデータの授受が行われている。機器３１２は例えば、電源部や電源制御、機器３１４がデータセンシング及びデータ処理、機器３１６がデータ記録等の役割を担っている。 For example, as shown in FIG. 14, the observation apparatus 300 for deep sea observation has lid portions 304 and 306 attached to both openings of the cylindrical body portion 302, and the cylindrical body portion 302 and the lid portions 304 and 306 are respectively disposed between the lid portions 304 and 306. O-ring 308 is interposed and sealed. A plurality of devices 312, 314, 316 are installed in the storage space 310 formed inside the cylindrical body 302, and the devices 312, 314, 316 are connected by connection wires 318, 320, and the devices 312, 314, Power is supplied to 316 and data is exchanged between devices. For example, the device 312 plays a role such as a power supply unit and power control, the device 314 performs data sensing and data processing, and the device 316 plays a role such as data recording.

このような観測機器３００に用いられる耐圧容器構造では、円筒胴部３０２の内径Ｒを小さくすれば、耐圧が高められ、強度的に有利となるが、その内容積Ｖを増加するには円筒胴部３０２の長さＬｓを長くすればよい。しかしながら、円筒胴部３０２を長くした場合、強度が低下し、これを回避するには、円筒胴部３０２の肉厚ｔを厚くする必要がある。肉厚ｔが厚くなれば、収納空間部３１０の内容積Ｖの増加が損なわれるし、観測機器３００の大型化、重量化は否めない。 In such a pressure vessel structure used in the observation apparatus 300, if the inner diameter R of the cylindrical body 302 is reduced, the pressure resistance is increased and the strength is advantageous. The length Ls of the part 302 may be increased. However, when the cylindrical body 302 is lengthened, the strength is lowered, and in order to avoid this, it is necessary to increase the thickness t of the cylindrical body 302. If the wall thickness t increases, the increase in the internal volume V of the storage space 310 is impaired, and the observation apparatus 300 cannot be increased in size and weight.

また、機能拡張のために新たな機器を追加搭載する場合等、例えば、図１５に示すように、拡張部３２２を増設して観測機器３００を構成する場合には、密閉された円筒胴部３０２の機器３１６と、拡張部３２２側の機器３２４とを接続することが必要となる。この場合、現状の観測機器３００側の蓋部３０６側に耐水圧コネクタ３２６、拡張部３２２側に耐水圧コネクタ３２８が取り付けられ、耐水圧コネクタ３２６、３２８間に耐水圧ケーブル３３０を繋ぐ必要がある。 Further, when a new device is additionally mounted for function expansion, for example, as shown in FIG. 15, when the observation device 300 is configured by adding the expansion unit 322, the sealed cylindrical body 302 is used. It is necessary to connect the device 316 and the device 324 on the expansion unit 322 side. In this case, it is necessary to attach the waterproof connector 326 to the lid 306 side of the current observation device 300 and the waterproof connector 328 to the extended portion 322, and connect the waterproof cable 330 between the waterproof connectors 326 and 328. .

このような耐水圧コネクタ３２６、３２８を用いた場合には、円筒胴部３０２を閉じる蓋部３０６と耐水圧コネクタ３２６との接続部分、拡張部３２２の蓋部３３２と耐水圧コネクタ３２８との接続部分の耐水圧が問題となり、機能拡張前より耐圧が低下する等、信頼性が低下する。一般に、耐水圧コネクタや耐水圧ケーブルは電気的接点部を耐水圧構造としなければならないので、耐水圧構造が不完全であれば、その構造部から漏水するおそれがある。このため、耐水圧コネクタは陸上使用のコネクタに比較して信頼性が低いと言われている。 When such a water pressure-resistant connector 326, 328 is used, the connection portion between the lid portion 306 that closes the cylindrical body 302 and the water pressure-resistant connector 326, and the connection between the lid portion 332 of the expansion portion 322 and the water pressure-resistant connector 328. The water pressure resistance of the part becomes a problem, and the reliability decreases, for example, the pressure resistance decreases before the function expansion. In general, since a water-resistant connector and a water-resistant cable must have an electrical contact portion having a water pressure resistant structure, if the water pressure resistant structure is incomplete, there is a risk of leakage from the structure portion. For this reason, it is said that the waterproof connector is less reliable than the connector for land use.

また、耐水圧コネクタ３２６、３２８や耐水圧ケーブル３３０の使用を回避するには、機能拡張を事前に想定し、円筒胴部３０２の全長を長く設定する等、収納空間部３１０に余裕を持たせることが必要となるが、不必要に円筒胴部３０２の長大化、重量化を来たし、現実的でない。即ち、円筒胴部３０２の長さＬｓ（図１４）を長くした場合、水圧下では強度が低下するため、円筒胴部３０２の肉厚ｔを厚くしなければならず、円筒胴部３０２が重くなるという不都合がある。 Further, in order to avoid the use of the water pressure resistant connectors 326 and 328 and the water pressure resistant cable 330, it is assumed that the function is expanded in advance, and the overall length of the cylindrical body 302 is set to be long. However, the cylindrical body 302 is unnecessarily long and heavy, which is not realistic. That is, when the length Ls (FIG. 14) of the cylindrical body 302 is increased, the strength decreases under water pressure. Therefore, the thickness t of the cylindrical body 302 must be increased, and the cylindrical body 302 is heavy. There is an inconvenience of becoming.

このような課題やそれを解決するための手段は、特許文献１等に開示されておらず、その示唆もない。 Such problems and means for solving them are not disclosed in Patent Document 1 or the like, and there is no suggestion thereof.

そこで、本発明の目的は、水中観測機器に関し、機能の拡張性を高め、機能拡張の容易化を図ることにある。 Accordingly, an object of the present invention relates to an underwater observation apparatus, and is to improve the expandability of functions and facilitate the function expansion.

また、本発明の他の目的は、水中観測機器の機能拡張に関し、耐水圧コネクタや耐水圧ケーブル等の特殊な部品を用いることなく、電子機器間の電気的接続の信頼性の低下を防止することにある。 Another object of the present invention relates to the expansion of the function of underwater observation equipment, and prevents a decrease in the reliability of electrical connection between electronic equipment without using special parts such as a water-resistant connector and a water-resistant cable. There is.

また、本発明の他の目的は、水中観測機器の機能拡張に関し、耐圧容器の長大化による耐圧強度の低下を抑制することにある。 Another object of the present invention relates to the expansion of the function of the underwater observation equipment, and is to suppress a decrease in the pressure strength due to the lengthening of the pressure vessel.
