Abstract

The ventilator for a ship's cabin (2) comprises an air intake (3) on the bridge (4) of the ship over an aperture (5) equipped with a shutter mechanism (6) with a seat (7) and a spring-loaded shutter (8). The shutter is held open by a spring (9) and closes automatically when water enters the air intake by the weight of the water collecting in a temporary holder (10). The holder has a series of holes (11) round its outer edge adjacent to the upper surface of the shutter so that it empties progressively and controls the opening of the shutter. The shutter can also be operated from inside the cabin by a control rod (16a) and handle (16b).

Description

La présente invention concerne un système d'aération d'un compartiment d'un navire.The present invention relates to an aeration system of a compartment of a ship.

Plus particulièrement, l'invention se rapporte à un système d'aération du type comportant une prise d'air telle qu'une manche à air, prévue sur le pont du navire, au-dessus d'un orifice d'aération du compartiment, ménagé dans ce pont, cet orifice étant muni d'un mécanisme à clapet comportant un siège de clapet, en saillie au-dessus du pont et associé à un organe d'obturation de celui-ci, déplaçable à l'encontre de la sollicitation de moyens élastiques entre une position d'ouverture du mécanisme à clapet, pour permettre l'aération du compartiment et une position de fermeture de celui-ci, par une masse d'eau pénétrant dans la prise d'air, pour éviter le passage de l'eau dans le compartiment.More particularly, the invention relates to a ventilation system of the type comprising an air intake such a windsock, provided on the deck of the ship, above a ventilation opening in the compartment, arranged in this bridge, this orifice being provided with a valve mechanism comprising a valve seat, projecting above the deck and associated with a movable closure member thereof against the demand for elastic means between an open position of the valve mechanism, to allow ventilation of the compartment and a position of closure thereof, by a body of water entering the air intake, to prevent the passage of water in the compartment.

On connaít déjà dans l'état de la technique, des systèmes d'aération de ce type, dans lesquels les moyens d'obturation du mécanisme à clapet se présentent sous la forme d'une coupelle inversée.We already know in the prior art, ventilation systems of this type, in which the means shutter mechanism are presented under the shape of an inverted cup.

On conçoit alors que lorsque des gouttes d'eau pénètrent dans la prise d'air, cet organe d'obturation en forme de coupelle inversée permet d'éviter que ces gouttes ne pénètrent dans le compartiment, en les canalisant vers des trous d'évacuation ménagés par exemple dans la partie inférieure de la prise d'air.We can then imagine that when drops of water enter the air intake, this shutter member in inverted cup shape prevents these drops do not enter the compartment, channeling them towards drainage holes provided for example in the part bottom of the air intake.

De plus, lorsqu'une masse d'eau importante pénètre dans la prise d'air, l'impact de celle-ci sur l'organe d'obturation amène celui-ci à se déplacer vers une position de fermeture du mécanisme à clapet contre le siège de clapet, à l'encontre de la sollicitation des moyens élastiques.In addition, when a large body of water enters in the air intake, its impact on the organ shutter causes it to move to a position for closing the flap mechanism against the seat valve, against requesting resources elastic.

Cependant, une telle structure présente un certain nombre d'inconvénients notamment lorsque les moyens élastiques repoussent l'organe d'obturation vers sa position d'ouverture après l'impact de la masse d'eau sur celui-ci. However, such a structure has a certain number of drawbacks especially when the means elastic push the shutter member towards its open position after the impact of the body of water on this one.

Il peut arriver en effet que la prise d'air ne soit pas totalement vidangée et que de l'eau reste dans le fond de celle-ci, autour du mécanisme à clapet.It may happen that the air intake is not not completely drained and water remains in the bottom of it, around the valve mechanism.

Dans une telle situation, le déplacement brusque de l'organe d'obturation en direction de sa position d'ouverture du mécanisme à clapet se traduit par le passage d'une quantité plus ou moins importante d'eau dans le compartiment, cet organe formant de plus une sorte de pompe à eau.In such a situation, the sudden displacement of the shutter in the direction of its position opening of the valve mechanism results in the passage more or less water in the compartment, this member also forming a sort of pump water.

Le but de l'invention est donc de résoudre ces problèmes.The object of the invention is therefore to resolve these problems.

A cet effet, l'invention a pour objet un système d'aération d'un compartiment d'un navire, du type comportant une prise d'air prévue sur le pont du navire, au-dessus d'un orifice d'aération du compartiment, ménagé dans ce pont, cet orifice étant muni d'un mécanisme à clapet comportant un siège de clapet en saillie au-dessus du pont et associé à un organe d'obturation de celui-ci, déplaçable à l'encontre de la sollicitation de moyens élastiques, entre une position d'ouverture du mécanisme à clapet, pour permettre l'aération du compartiment et une position de fermeture de celui-ci, par une masse d'eau pénétrant dans la manche à air, pour éviter le passage de l'eau dans le compartiment, caractérisé en ce que l'organe d'obturation comporte des moyens de retenue temporaire d'eau munis de moyens de vidange progressive de celle-ci, pour contrôler le déplacement de cet organe d'obturation de sa position de fermeture vers sa position d'ouverture du mécanisme à clapet et en ce que l'organe d'obturation présente une portion centrale en forme de dôme s'étendant au-dessus du siège de clapet et une portion périphérique en forme de gouttière de retenue d'eau s'étendant autour de ce siège de clapet, dont la partie inférieure est munie d'au moins un trou de vidange d'eau.To this end, the invention relates to a system ventilating a compartment of a ship, of the type comprising an air intake provided on the deck of the ship, above a compartment ventilation opening in this bridge, this orifice being provided with a mechanism valve having a valve seat projecting above of the bridge and associated with a closure member thereof, movable against the request of means elastic, between an open position of the mechanism flap, to allow ventilation of the compartment and a closing position thereof, by a body of water penetrating the wind sock, to avoid the passage of water in the compartment, characterized in that the organ shutter includes temporary retention means of water provided with means for gradually draining it, to control the movement of this shutter member its closed position to its open position of the valve mechanism and in that the shutter member has a central dome-shaped portion extending above the valve seat and a peripheral portion in form of water retaining gutter extending around it valve seat, the lower part of which is provided with minus a water drain hole.

L'invention sera mieux comprise à l'aide de la description qui va suivre, donnée uniquement à titre d'exemple et faite en se référant aux dessins annexés, sur lesquels :

  • les Figs.1 à 4 représentent des vues schématiques en coupe d'un tel système d'aération illustrant le fonctionnement de celui-ci.
The invention will be better understood with the aid of the description which follows, given solely by way of example and made with reference to the appended drawings, in which:
  • Figs.1 to 4 show schematic sectional views of such a ventilation system illustrating the operation thereof.

On reconnaít en effet sur ces figures, un système d'aération désigné par la référence générale 1 d'un compartiment d'un navire, désigné par la référence générale 2 sur ces figures.We recognize in these figures, a system designated by the general reference 1 of a compartment of a ship, designated by the general reference 2 in these figures.

Un tel système d'aération comporte de façon classique une prise d'air telle qu'une manche à air désignée par la référence générale 3, prévue sur le pont par exemple 4 du navire, au-dessus d'un orifice d'aération 5 du compartiment 2 de celui-ci, cet orifice d'aération 5 étant ménagé dans ce pont.Such a ventilation system includes classic an air intake such as a windsock designated by the general reference 3, provided on the deck for example 4 of the ship, above a ventilation opening 5 of compartment 2 thereof, this ventilation opening 5 being spared in this bridge.

De plus, cet orifice 5 est muni d'un mécanisme à clapet désigné par la référence générale 6, comportant un siège de clapet 7 en saillie au-dessus du pont et associé à un organe d'obturation de celui-ci désigné par la référence générale 8.In addition, this orifice 5 is provided with a mechanism valve designated by general reference 6, comprising a valve seat 7 projecting above the deck and associated with a shutter body thereof designated by the reference general 8.

Comme cela sera décrit plus en détail par la suite, cet organe d'obturation 8 est déplaçable à l'encontre de la sollicitation de moyens élastiques, désignés par la référence générale 9, entre une position d'ouverture du mécanisme à clapet 6 (Fig.1) pour permettre l'aération du compartiment 2 et une position de fermeture (Fig.2) de celui-ci, par une masse d'eau pénétrant dans la manche à air, pour éviter le passage de l'eau dans le compartiment.As will be described in more detail later, this shutter member 8 is movable against the solicitation of elastic means, designated by the general reference 9, between an open position of the valve mechanism 6 (Fig. 1) to allow ventilation of the compartment 2 and a closed position (Fig. 2) of this one, by a mass of water penetrating in the sleeve to air, to prevent the passage of water in the compartment.

Selon l'invention, l'organe d'obturation 8 comporte des moyens 10 de retenue temporaire d'eau munis de moyens 11 de vidange progressive de celle-ci, pour contrôler le déplacement de cet organe d'obturation 8 de sa position de fermeture vers sa position d'ouverture du mécanisme à clapet 6.According to the invention, the shutter member 8 comprises means 10 for temporary water retention provided with means 11 progressive emptying thereof, to control the displacement of this shutter member 8 from its position closing towards its open position of the mechanism valve 6.

Comme cela est représenté sur ces figures, cet organe d'obturation peut par exemple comporter une portion centrale désignée par la référence générale 12, en forme de dôme, s'étendant au-dessus du siège 7 de clapet et une portion périphérique 13 en forme de gouttière de retenue d'eau s'étendant autour de ce siège de clapet.As shown in these figures, this shutter member may for example comprise a portion control unit designated by the general reference 12, in the form of dome, extending above the valve seat 7 and a peripheral portion 13 in the form of a retaining gutter of water extending around this valve seat.

Cette gouttière 13 de retenue d'eau constitue alors les moyens de retenue temporaire de celle-ci décrits précédemment. La partie inférieure de cette portion périphérique en forme de gouttière de retenue d'eau peut être munie d'au moins un trou de vidange de celle-ci, constituant les moyens de vidange 11 décrits précédemment.This gutter 13 for retaining water then constitutes the temporary retention means described therein previously. The lower part of this portion device in the form of a water retaining gutter can have at least one drain hole, constituting the drain means 11 described above.

De plus, cette portion périphérique de l'organe d'obturation 8 peut également comporter une nervure périphérique désignée par la référence générale 14 sur ces figures, adaptée pour former, lorsque l'organe d'obturation 8 est en position de fermeture du mécanisme à clapet, en coopération avec le pont 4 du navire, des moyens de freinage du passage de l'eau entre cet organe d'obturation et le siège de clapet.In addition, this peripheral portion of the organ shutter 8 may also include a rib peripheral designated by the general reference 14 on these figures, adapted to form, when the shutter member 8 is in the closed position of the valve mechanism, in cooperation with deck 4 of the ship, means of braking of the passage of water between this shutter member and the valve seat.

Comme on l'a indiqué précédemment, l'organe d'obturation 8 est également sollicité par des moyens élastiques.As previously indicated, the organ shutter 8 is also requested by means elastic.

Ces moyens ont été désignés par la référence générale 9 sur ces figures et peuvent par exemple comporter un ressort hélicoïdal disposé dans le prolongement d'un manchon 15, prévu au centre du mécanisme à clapet. Ce manchon est adapté pour recevoir par exemple un organe de manoeuvre 16 de l'organe d'obturation 8 pour permettre à un utilisateur de commander sa position et de placer celui-ci par exemple dans une position stable d'obturation du mécanisme à clapet.These means have been designated by the reference general 9 in these figures and may for example include a helical spring arranged in the extension of a sleeve 15, provided in the center of the valve mechanism. This sleeve is adapted to receive, for example, a operation 16 of the shutter member 8 to allow a user to control its position and place it for example in a stable position for closing the flap mechanism.

A cet effet, ces moyens de manoeuvre comportent par exemple une tige 16a présentant à une première extrémité une poignée de manoeuvre 16b par l'utilisateur et reliée à son autre extrémité, par exemple en 16c, à l'organe d'obturation. To this end, these maneuvering means include example a rod 16a having at a first end an operating handle 16b by the user and connected to its other end, for example in 16c, to the organ shutter.

Des moyens de blocage de cet organe d'obturation en position de fermeture du mécanisme à clapet sont associés à la tige ou à la poignée, de façon classique.Means for blocking this shutter member in closing position of the valve mechanism are associated with the rod or the handle, in a conventional manner.

On conçoit alors que le fonctionnement d'un tel système est le suivant.We then understand that the functioning of such a system is as follows.

Dans la position représentée sur la figure 1, l'organe d'obturation 8 est en position d'ouverture du mécanisme à clapet, de sorte que le compartiment 2 du navire est ventilé.In the position shown in Figure 1, the shutter member 8 is in the open position of the flap mechanism, so that compartment 2 of the ship is ventilated.

Lorsque des gouttes d'eau pénètrent dans la manche à air, la portion centrale 12 en forme de dôme de cet organe d'obturation 8 permet de diriger celles-ci en direction des moyens 10 de retenue temporaire de celle-ci, cette eau étant ensuite évacuée à travers les trous de vidange 11 de cet organe d'obturation et des trous de vidange de la manche à air dont l'un est désigné par la référence générale la sur cette figure.When drops of water get into the sleeve air, the central dome-shaped portion 12 of this obturation member 8 makes it possible to direct them in direction of the temporary retention means 10 thereof, this water then being discharged through the holes of emptying 11 of this obturation member and of the holes emptying the air bag, one of which is designated by the general reference la in this figure.

Si une masse d'eau importante pénètre dans la manche à air, celle-ci va alors tomber sur l'organe d'obturation 8, ce qui va permettre comme on peut le voir sur la figure 2, de remplir au moins partiellement les moyens de retenue temporaire d'eau 10 de l'organe d'obturation 8.If a large body of water enters the windsock, it will then fall on the organ shutter 8, which will allow as we can see in FIG. 2, to fill at least partially the temporary water retention means 10 of the organ shutter 8.

Sous l'effet de l'impact de cette masse d'eau et de la quantité d'eau remplissant les moyens de retenue 10, l'organe d'obturation 8 du mécanisme à clapet se déplace alors à l'encontre de la sollicitation des moyens élastiques 9 vers la position d'obturation de celui-ci, représentée sur la figure 2.Under the effect of the impact of this body of water and the quantity of water filling the retaining means 10, the shutter member 8 of the valve mechanism moves then against the request of the means elastic 9 towards the closed position thereof, shown in figure 2.

On peut en effet constater sur cette figure, que l'organe d'obturation 8 vient en contact contre le siège de clapet 7 pour empêcher l'eau de pénétrer dans le compartiment, la nervure 14 de celui-ci venant également à proximité du pont du navire pour freiner le passage d'eau entre cet organe d'obturation et le siège de clapet. We can see in this figure that the shutter member 8 comes into contact against the seat of valve 7 to prevent water from entering the compartment, the rib 14 thereof also coming to close to the ship's deck to slow down the passage of water between this shutter member and the valve seat.

Comme on peut le voir sur la figure 3, la masse d'eau peut alors être évacuée de la manche à air par les trous de vidange la de celle-ci, l'organe d'obturation 8 restant en position de fermeture du mécanisme à clapet, du fait du poids de l'eau retenue dans les moyens de retenue de celle-ci.As can be seen in Figure 3, the mass water can then be evacuated from the air bag by the drain holes therefrom, the shutter member 8 remaining in the closed position of the valve mechanism, made the weight of the water retained in the retaining means of it.

Lorsque le niveau d'eau dans la manche à air devient inférieur à celui de l'eau contenue dans les moyens de retenue d'eau de l'organe d'obturation, l'eau retenue dans ces moyens peut se vidanger à travers le ou chaque trou de vidange 11 de ceux-ci, en direction des trous de vidange la de la manche à air et ce, de façon progressive, pour permettre, comme on peut le voir sur la figure 4, la remontée progressive de l'organe d'obturation 8 vers sa position d'ouverture du mécanisme à clapet, afin de permettre à nouveau l'aération du compartiment 2 du navire.When the water level in the windsock becomes lower than that of the water contained in the means water retaining member of the obturation member, the retained water in these ways can drain through the or each drain hole 11 of these, towards the holes of emptying the air bag and this, gradually, to allow, as can be seen in Figure 4, the progressive ascent of the shutter member 8 towards its flap mechanism open position, to allow ventilation of compartment 2 of the ship again.

On notera à cet égard, qu'en position de fermeture, les moyens de retenue d'eau de l'organe d'obturation, s'étendent à un niveau au plus égal à celui du siège de clapet, ce qui permet d'éviter tout passage d'eau dans le compartiment lors du déplacement de l'organe d'obturation vers sa position d'ouverture.It should be noted in this regard, that in the closed position, the means for retaining water from the obturation member, extend to a level at most equal to that of the seat of valve, which avoids any passage of water in the compartment during movement of the shutter member towards its open position.

On conçoit alors que le système d'aération selon l'invention présente un certain nombre d'avantages par rapport aux systèmes classiques de l'état de la technique, dans la mesure où les moyens de retenue temporaire d'eau à vidange progressive de l'organe d'obturation de celui-ci permettent de contrôler les déplacements de cet organe d'obturation de sa position de fermeture vers sa position d'ouverture du mécanisme à clapet, afin d'éviter tout passage d'eau à travers l'orifice ménagé dans le pont du navire en n'autorisant le déplacement de cet organe vers sa position d'ouverture que lorsque la manche à air est suffisamment vidangée. It is therefore conceivable that the ventilation system according to the invention has a number of advantages by compared to conventional systems of the state of the art, insofar as the temporary water retention means to progressive emptying of the shutter member thereof allow to control the movements of this organ shutter from its closed position to its position opening of the flap mechanism, in order to avoid any passage of water through the opening in the bridge of the ship by not authorizing the movement of this organ towards its open position only when the windsock is sufficiently drained.

Il va de soi bien entendu que différents modes de réalisation de ce système d'aération et en particulier de l'organe d'obturation peuvent être envisagés.It goes without saying of course that different modes of realization of this ventilation system and in particular of the shutter member can be considered.
