Abstract
Description
本発明は、潜水艇に関する。 The present invention relates to a submersible boat.
潜水艇が、魚類の鑑賞等のレジャーにも用いられている。レジャー用の潜水艇は、搭乗スペースの上方に外部が見えるように透明なキャノピーが設けられ、キャノピーによって搭乗スペースと外部とが隔てられている。また、キャノピーを開閉して乗り降りする。 Submersibles are also used for leisure such as watching fish. Leisure submersibles have a transparent canopy above the boarding space so that the outside can be seen, and the canopy separates the boarding space from the outside. Also, open and close the canopy to get on and off.
ここで、開閉可能なキャノピーは、潜水時にその周縁から浸水してしまう可能性がある。そこで、例えば特許文献１に開示されたように、浸水を防止する。 Here, the openable canopy may be flooded from its peripheral edge when diving. Therefore, for example, as disclosed in Patent Document 1, infiltration of water is prevented.
浸水の防止は、キャノピーの周縁が圧接される開閉部に、例えばゴム製のＯリングを設け、キャノピーと開閉部との間を水が流れることを防止することで実現される。搭乗スペース内外の差圧によって、キャノピーが開閉部に圧接されることを利用するものである。 The prevention of water infiltration is realized by providing, for example, a rubber O-ring at the opening / closing portion with which the peripheral edge of the canopy is in pressure contact, and preventing water from flowing between the canopy and the opening / closing portion. It utilizes that the canopy is pressed against the opening / closing part due to the differential pressure inside and outside the boarding space.
浅深度においては、搭乗スペース外の水圧が小さく、搭乗スペース内外の差圧は、極めて小さい。このため、キャノピーの圧接が弱く、浸水してしまう可能性がある。搭乗者の快適のため、搭乗スペース内は１気圧程度に調製される。そうすると、潜水開始前には、搭乗スペース内外の差圧がなく、キャノピーが開閉部に圧接されていない。この状態から潜水すれば、潜水開始時に浸水してしまうリスクが大きい。 At shallow depths, the water pressure outside the boarding space is small, and the differential pressure inside and outside the boarding space is extremely small. For this reason, the pressure contact of the canopy is weak, and there is a possibility that it will be flooded. For the comfort of passengers, the inside of the boarding space is adjusted to about 1 atm. Then, before starting the dive, there is no pressure difference between the inside and outside of the boarding space, and the canopy is not pressed against the opening / closing part. If you dive from this state, there is a large risk of flooding at the start of diving.
従来は、キャノピーをヒンジ止めする等の手段で固定し、浸水を防止した。しかし、ヒンジ止めでは、ヒンジの位置によってキャノピーの周縁が非一様な力で開閉部に圧接される。そうすると、圧接力の弱い箇所から浸水してしまう可能性があった。 Conventionally, the canopy is fixed by means such as a hinge to prevent water from entering. However, with the hinge stopper, the peripheral edge of the canopy is pressed against the opening / closing portion with a non-uniform force depending on the position of the hinge. Then, there is a possibility that water will be infiltrated from the place where the pressure contact force is weak.
そこで、本発明は、開閉可能なキャノピーを有しつつも、潜水開始時に浸水してしまうことのない潜水艇を提供することを課題とする。 Therefore, it is an object of the present invention to provide a submersible boat that has an openable and closable canopy and does not flood when starting diving.

この特徴によれば、潜水開始前に、搭乗スペース内の気圧を外圧（浮上した状態における水面上の気圧）よりも小さくして、キャノピーを開閉部に圧接することができる。潜水開始時に浸水してしまうことが防止される。 According to this feature, the pressure in the boarding space can be made smaller than the external pressure (the pressure on the water surface in the floating state) before the dive starts, and the canopy can be pressed against the opening / closing portion. It is possible to prevent inundation at the start of diving.

以下、本発明の実施例を説明する。 Examples of the present invention will be described below.
図１は、潜水艇を示す図である。潜水艇１には、透明なキャノピー２が設けられ、キャノピー２を開閉して搭降乗する。キャノピー２の下端は開閉部３に当接し、潜水時の浸水を防止している。 FIG. 1 is a diagram showing a submersible. The submersible boat 1 is provided with a transparent canopy 2 for opening and closing the canopy 2 to get on and off. The lower end of the canopy 2 is in contact with the opening / closing part 3 to prevent water from entering during diving.
図２は、潜水艇の構造を示す断面図である。図１におけるＣ−Ｃ線の断面を示す。キャノピー２は、潜水艇１の内部の搭乗スペース４と外部とを分離している。 FIG. 2 is a sectional view showing the structure of the submersible. The cross section of the CC line in FIG. 1 is shown. The canopy 2 separates the boarding space 4 inside the submersible 1 from the outside.
搭乗スペース４には、座席４１が設けられて搭乗者の快適を確保すると共に、蓄圧器５が設けられている。また、搭乗スペース４と外部との気圧差を測定する差圧計６が設けられている。 In the boarding space 4, a seat 41 is provided to ensure passenger comfort and a pressure accumulator 5 is provided. Further, a differential pressure gauge 6 for measuring a pressure difference between the boarding space 4 and the outside is provided.
図３は、キャノピーを開いた状態を示す図である。キャノピー２は、ヒンジ２１を中心に回転して開閉する。ヒンジ２１は、キャノピー２と開閉部３との当接に影響しない箇所に設けられている。 FIG. 3 is a diagram showing a state in which the canopy is opened. The canopy 2 opens and closes by rotating around a hinge 21. The hinge 21 is provided at a location that does not affect the contact between the canopy 2 and the opening / closing section 3.
図４は、開閉部を示す平面図である。開閉部３は、図４（Ａ）に示すように、キャノピー２の周縁（底面）に合わせた円形状であり、その表面は平面状である。キャノピー２の周縁も平面状であり、キャノピー２の周縁が一様に（ほぼ等圧で）開閉部３に圧接される。キャノピー２の周縁において開閉部３への圧接が弱い箇所はない。 FIG. 4 is a plan view showing the opening / closing section. As shown in FIG. 4 (A), the opening / closing part 3 has a circular shape that matches the peripheral edge (bottom surface) of the canopy 2, and the surface thereof is planar. The peripheral edge of the canopy 2 is also flat, and the peripheral edge of the canopy 2 is uniformly (at substantially equal pressure) pressed against the opening / closing section 3. There is no portion where the pressure contact with the opening / closing portion 3 is weak on the peripheral edge of the canopy 2.
ここで、開閉部３は、図４（Ｂ）に示すように、Ｏリング３１を備えることが好ましい。Ｏリング３１は、ゴム等の弾性体であり、その弾性によってキャノピー２に密着し、浸水を防ぐ。 Here, it is preferable that the opening / closing part 3 includes an O-ring 31, as shown in FIG. The O-ring 31 is an elastic body such as rubber, and adheres to the canopy 2 by its elasticity to prevent water from entering.
図５は、開閉部を示す断面図である。図４（Ｂ）に示すＯリング３１を備えるものである。キャノピー２を開いた状態では、図５（Ａ）に示すように、Ｏリング３１が開閉部３から突出している。キャノピー２を閉じると、図５（Ｂ）に示すように、Ｏリング３１が圧縮されてキャノピー２に密着する。この密着により、浸水を防ぐ。 FIG. 5 is a cross-sectional view showing the opening / closing section. The O-ring 31 shown in FIG. 4B is provided. When the canopy 2 is opened, the O-ring 31 projects from the opening / closing part 3 as shown in FIG. When the canopy 2 is closed, the O-ring 31 is compressed and comes into close contact with the canopy 2, as shown in FIG. This close contact prevents water infiltration.
以下、潜水開始時の浸水の防止について説明する。 Hereinafter, prevention of inundation at the start of diving will be described.
潜水開始前に、キャノピー２を閉じ、ポンプ５１を作動させて搭乗スペース４内の空気を蓄圧器５に送る。これにより、搭乗スペース４内の気圧が外部よりも低くなる。 Before starting the dive, the canopy 2 is closed and the pump 51 is operated to send the air in the boarding space 4 to the pressure accumulator 5. As a result, the air pressure inside the boarding space 4 becomes lower than that outside.
その結果、差圧によってキャノピー２の周縁が開閉部３に圧接される。ここで、一様に圧接されているので、キャノピー２の周縁の一部が開閉部３から離脱しやすい（浸水する）ことはない。 As a result, the peripheral edge of the canopy 2 is brought into pressure contact with the opening / closing portion 3 due to the pressure difference. Here, since the canopy 2 is pressed uniformly, a part of the peripheral edge of the canopy 2 does not easily come off from the opening / closing part 3 (immers in water).
圧接の強度は、差圧計６によって把握することができる。潜水開始時に浸水しないだけの差圧となるように蓄圧器に送る空気の量を調整することができる。 The strength of the pressure contact can be grasped by the differential pressure gauge 6. The amount of air sent to the pressure accumulator can be adjusted so that the pressure difference is such that no water is flooded at the start of diving.
ポンプが例えば電気によって駆動されるのであれば、駆動部（非図示）によってポンプ５１を駆動し、駆動部が差圧計６からの信号を受けて、所定の差圧となった時にポンプ５１を停止して、所定の差圧を実現することができる。 If the pump is driven by electricity, for example, the drive unit (not shown) drives the pump 51, and the drive unit receives the signal from the differential pressure gauge 6 and stops the pump 51 when a predetermined differential pressure is reached. Then, a predetermined differential pressure can be realized.
ここで、所定に差圧の値は設計事項として定めてよいが、例えば５０ヘクトパスカルとすることができる。外圧が１０００ヘクトパスカル、搭乗スペース４内の気圧が９５０ヘクトパスカルであり、Ｏリング３１を用いれば、潜水開始時の浸水を防止することができる。 Here, the value of the differential pressure may be predetermined as a design item, but may be 50 hectopascals, for example. The external pressure is 1000 hectopascals, the atmospheric pressure in the boarding space 4 is 950 hectopascals, and if the O-ring 31 is used, it is possible to prevent inundation at the start of diving.
所定の差圧又はそれよりも大きな差圧として、潜水を開始する。これにより、浸水を防止することができる。 Diving is started as a predetermined differential pressure or a greater differential pressure. This makes it possible to prevent water from entering.
開閉可能なキャノピーを有しつつも、潜水開始時に浸水してしまうことのない潜水艇である。多くのマリンレジャー提供者による利用が考えられる。 It has a canopy that can be opened and closed, but it is a submersible that does not submerge when the dive starts. It can be used by many marine leisure providers.
