Description

  The present invention relates to a ship equipped with a watertight door.

  In ships such as ships, a plurality of watertight sections are generally formed inside the hull. In the watertight section, a space between two decks adjacent to each other in the upper and lower portions is formed by being separated by a longitudinal bulkhead extending in the ship's forward direction and a transverse bulkhead extending in the lateral direction. The water-tight section formed in this way has an opening so that a worker or the like can go in and out. A watertight door that can be opened and closed by a hinge is attached so that it can be walked in and out without using a ladder etc., especially in a watertight section where the frequency of entering and exiting is high, and a watertight section where it is necessary to install equipment etc. .

  Although it is not a door for ships, the technique which makes barrier-free the waterproof door which can prevent the penetration of water is described in patent document 1.

JP, 2014-34841, A

By the way, in the watertight door of a ship, it is necessary to install a sealing device over the entire circumference of the opening of the watertight bulkhead such as the horizontal bulkhead and the longitudinal bulkhead. That is, it is necessary to provide a seal bearing surface for sandwiching the seal device between the watertight door and the lower part of the opening, and the lower edge of the opening protrudes from the floor surface. Therefore, there is a problem that the protruding portion stumbles in the protruding portion or the protruding portion becomes an obstacle when transporting a heavy load with a carriage or the like.
In addition, the waterproof door described in Patent Document 1 is configured such that the floor surface portion can be made barrier-free when the waterproof door is not used by inserting and removing the water blocking holding frame from the floor surface portion. However, in the case of a ship, since the lower side of the door is a deck, it is not possible to substantially secure a space for accommodating the water blocking holding frame.
This invention is made in view of the said situation, and provides the ship which can carry in and out a heavy load etc. easily with respect to a watertight section.

In order to solve the above problems, the following configuration is adopted.
According to the first aspect of the present invention, the vessel is disposed so as to cross the decks vertically adjacent to each other to form a watertight partition forming a watertight section, and a watertight door capable of opening and closing the opening formed in the watertight partition. And a seal attaching surface continuously formed on the entire periphery of the outer periphery of the watertight door, and when the watertight door is closed, the watertight door is compressed and deformed, and between the watertight door and the watertight partition wall A sealing device for securing watertightness, the outer peripheral portion includes a lower edge portion extending along the deck disposed downward, and the seal mounting surface formed at the lower edge portion is a lower portion.

That is, it is not necessary to form a surface facing in the horizontal direction, which is the direction in which the watertight door is opened, at the lower edge of the opening. Therefore, the height of the lower edge of the opening facing the first seal mounting surface can be reduced.
Therefore, it is possible to easily put in and out heavy items and the like from the watertight section.

According to the second aspect of the present invention, the watertight door according to the first aspect displaces the first seal attachment surface in the width direction, and the first pressing mechanism displaces the first seal attachment surface in the vertical direction. A second pressing mechanism may be provided.
With this configuration, the seal device disposed between the first seal attachment surface and the lower edge of the opening can be sufficiently compressed and deformed by the first pressing mechanism. In addition, the seal device disposed between the second seal attachment surface and the lower edge of the opening can be sufficiently compressed and deformed by the second pressing mechanism.
Therefore, sufficient water tightness between the water tight door and the lower edge of the opening can be ensured.

In this way, for example, while closing the watertight door, it is possible for people in the watertight compartment to move in and out through the child door. In addition, when water that does not reach the lower opening edge of the child door opening flows along the floor surface, water flowing along the floor surface is made watertight while allowing people to enter and leave the watertight section. It can suppress flowing into the compartment. Furthermore, since a general seal mechanism can be used as a seal mechanism using the child door seal device, the procedure at the time of opening and closing can be simplified. Therefore, the child door can be easily opened and closed.

According to the fifth aspect of the present invention, the watertight door according to any one of the first to fourth aspects is provided with a slit on each of the first seal attachment surface and the second seal attachment surface. Good.
By comprising in this way, a 1st seal attachment surface and a 2nd seal attachment surface can be displaced easily. Therefore, the seal device attached to the first seal attachment surface and the second seal attachment surface can be easily compressed and deformed.

According to the sixth aspect of the present invention, the watertight partition wall according to any one of the first to fifth aspects is formed to project in the opposite direction to the watertight door in the thickness direction thereof It is formed to rise upward from the first seal facing surface formed facing upward, and both end edges of the first seal facing surface in the width direction of the watertight door, and the opening in the width direction Even with the second seal opposing surface formed facing inward, and the third seal opposing surface formed extending horizontally from the side near the watertight door among the second seal opposing surfaces.

The third seal mounting surface 22 is formed to face the closing direction Dc of the watertight door 10, similarly to the upper edge 14a, the left edge 14c, and the right edge 14b of the outer peripheral portion 14 described above. In addition, although the case where the seal | sticker attachment surface 15 in this embodiment is formed in planar shape is illustrated, it should just be a shape which the sealing apparatus 16 requires, and is not restricted to planar shape.

  As shown in FIG. 4 to FIG. 6, the sealing device 16 is compressed and deformed by being sandwiched between the watertight door 10 and the watertight partition 7 to seal the gap between the watertight door 10 and the watertight partition 7 Secure sex. The seal device 16 is attached to the seal mounting surface 15 described above. The sealing device 16 is formed to be continuous with the entire circumference of the outer peripheral portion 14. The sealing device 16 in this embodiment is formed of rubber or the like, and is formed in a flat plate shape that is thin in the direction in which it is compressed. Of the sealing device 16, the portions attached to the upper edge 14a, the left edge 14c, and the right edge 14b of the parent door 11 are each formed in a strip shape in which the direction in which the watertight door 10 opens and closes is the thickness direction. ing.

The seal device 16 includes a first seal portion 16a, a second seal portion 16b, and a third seal portion 16c, which are disposed at the lower edge portion 14d of the parent door 11, respectively.
The first seal portion 16 a is formed in a flat plate shape (strip shape) along the first seal attachment surface 20 formed on the lower edge portion 14 d described above.
The second seal portion 16 b is formed to rise upward from both end portions of the first seal portion 16 a. More specifically, as shown in FIG. 6, the second seal portion 16b in this embodiment has a concave surface 16bo in close contact with the convex curved surface 17b formed at the corner of the projecting portion 17 at the portion rising upward. A convex curved surface 16bt having a radius of curvature larger than that of the concave curved surface 16bo is provided on the outer side, as well as on the inner side closer to the protrusion 17. The thickness T2 of the second seal portion 16b in this embodiment is formed larger than the thickness T1 of the first seal portion 16a. The upper end surface 16bu of the second seal portion 16b is disposed at the same position as the upper surface 17a of the projection 17 in the vertical direction.

  The third seal portion 16c is formed to extend laterally (in other words, in the horizontal direction) from the edge portion 16be of the second seal portion 16b in the opening direction Do. More specifically, the third seal portion 16 c is formed in a flat plate shape (strip shape) in which the upper and lower sides become the width direction and extend in the horizontal direction. The seal device 16 attached to the left edge 14c and the right edge 14b of the parent door 11 extends upward from the outer end of the third seal portion 16c.

  As shown in FIG. 4 and FIG. 6, the watertight partition wall 7 is provided with the first seal opposing surface 30, the second seal opposing surface 31, and the third seal opposing surface 32 at the lower edge of the opening 9. There is. The first seal opposing surface 30, the second seal opposing surface 31, and the third seal opposing surface 32 are the first seal mounting surface 20 and the second seal mounting surface 21 when the watertight door 10 is closed. And the third seal mounting surface 22 are disposed to face each other. The third seal mounting surface 22 is disposed so as to be able to sandwich the third seal portion 16c between the third seal facing surface 32 and the third seal facing surface 32 so as to have a predetermined crushing margin uniformly in the left-right direction.

  The lower edge of the opening 9 is formed with a recess 35 recessed downward, and a horizontal plate 37 extending from the bottom 36 of the recess 35 in the closing direction Dc, and rising upward from both left and right sides of the horizontal plate 37 A vertical plate portion 38 is formed. The upper surface of the horizontal plate portion 37 is the first seal opposing surface 30, and two side surfaces of the two vertical plate portions 38 opposing each other are the second seal opposing surface 31. The horizontal plate portion 37 is disposed along the upper surface of the deck 6 disposed below and is disposed to abut on the deck 6. That is, the lower edge of the opening 9 protrudes only from the deck 6 by the thickness T3 (see FIG. 6) of the horizontal plate portion 37 because the recess 35 is formed.

  That is, the first seal opposing surface 30 is formed to project in the direction (the closing direction Dc) opposite to the watertight door 10 in the direction in which the watertight partition 7 is opened and closed, and to face upward. And although the 1st seal opposing surface 30 in this embodiment is formed so that it may become substantially parallel to the 1st seal attachment surface 20 in the state where the watertight door 10 was closed, it is not restricted parallel .

  Further, the second seal opposing surface 31 is formed to rise upward from the both end edges of the first seal opposing surface 30 in the width direction of the watertight door 10, that is, the left edge and the right edge. Each of the openings 9 is formed so as to face inward in the width direction of the opening 9 (in other words, to face each other). In addition, the convex curved surface 17b formed in the corner of the 1st seal attachment surface 20 mentioned above and the 2nd seal attachment surface 21 in the corner part which the 1st seal opposing surface 30 and the 2nd seal opposing surface 31 connect. Opposing concave curved surfaces 39 are formed.

  The third seal opposing surface 32 is formed to extend in the horizontal direction from an end 32 a of the second seal opposing surface 31 which is closer to the watertight door 10. The third seal facing surface 32 in this embodiment is a vertical surface (see FIG. 5).

FIG. 7 is a perspective view showing a schematic configuration of the first pressing mechanism and the second pressing mechanism in the embodiment of the present invention.
As shown in FIG. 7, the parent door 11 further includes an accommodation recess 40, a first pressing mechanism 41, and a second pressing mechanism 42.
The accommodation recess 40 is formed in the lower edge portion 14 d, and accommodates the first pressing mechanism 41 and the second pressing mechanism 42 inside the above-described protrusion 17. The housing recess 40 forms a rectangular parallelepiped space that opens in the opening direction Do of the watertight door 10. A first slit 44 is formed on the bottom wall 43 of the housing recess 40. The first slit 44 is formed vertically through the bottom wall 43 along the outer peripheral edge of the bottom wall 43 in a U-shape in top view in order to make the bottom wall 43 displaceable in the vertical direction. As a result, the first seal mounting surface 20 formed on the bottom of the bottom wall 43 is vertically displaceable.

  Similarly, second slits 46 are formed in the two side walls 45 of the housing recess 40 respectively. The second slits 46 are formed to pass through the side wall 45 in a rectangular shape along the outer peripheral edge of the side wall 45 so as to allow the side wall 45 to be displaced in the left-right direction. As a result, most of the second seal mounting surface 21 which is the outer surface of the side wall 45 is displaceable in the left-right direction. In addition, the 1st slit 44 and the 2nd slit 46 are not restricted to the said structure. For example, the bottom wall 43 may be formed like a cantilever, and the bottom wall 43 may be vertically displaced by elastic deformation of the bottom wall 43. Similarly, the side wall 45 may be formed like a cantilever so that the side wall 45 can be displaced laterally by elastic deformation of the side wall 45.

  The first pressing mechanism 41 displaces the first seal mounting surface 20 in the vertical direction. The first pressing mechanism 41 can press the bottom wall 43 described above downward to displace the first seal mounting surface 20 in the vertical direction. The first seal mounting surface 20 in this embodiment exemplifies a case where the bottom wall 43 is displaced up and down by the screw action of a bolt or the like, with the upper wall 47 opposed to the bottom wall 43 as a fulcrum.

  For example, when the first seal attachment surface 20 is displaced downward by the first pressing mechanism 41 in a state where the parent door 11 is closed, the first seal portion 16a is the first seal attachment surface 20 and the first seal opposing surface 30. It is inserted between and compression deformation is done. Thereby, the space between the first seal mounting surface 20 and the first seal opposing surface 30 is sealed. On the contrary, when the first seal attachment surface 20 is displaced upward by the first pressing mechanism 41, the force pressing against the first seal portion 16a is released. The first pressing mechanism 41 is not limited to one using a screw action. For example, a pressing mechanism using hydraulic pressure or the like may be used. Further, the operation of the first pressing mechanism 41 may be controlled not only manually but also via an actuator or the like (the same applies to the second pressing mechanism 42).

  The second pressing mechanism 42 displaces the second seal mounting surface 21 in the left-right direction. The second pressing mechanism 42 presses the side wall 45 disposed on the right side in the right direction and presses the side wall 45 disposed on the left side in the left direction so as to displace the second seal mounting surface 21 in the left and right direction. It has become possible. The second seal mounting surface 21 in this embodiment exemplifies a case where the side walls 45 facing each other are separated and brought close to each other by a screw action of a bolt or the like.

  For example, when the second pressing mechanism 42 displaces the two second seal attachment surfaces 21 to the left and right with the parent door 11 closed, the left and right second seal portions 16 b are the second seal attachment surfaces. 21 and the second seal opposing surface 31 to be compressed and deformed. Thereby, the space between the second seal attachment surface 21 and the second seal opposing surface 31 is sealed. On the other hand, when the second seal attachment surface 21 is displaced to the left and right by the second pressing mechanism 42, the force pressing against the second seal portion 16b is released. Similarly to the first pressing mechanism 41 described above, the second pressing mechanism 42 is not limited to one using a screw action.

  As shown in FIG. 3, the child door 12 is attached with a child door seal device 50 continuous to the entire periphery of the outer peripheral portion 12a of the surface facing the closing direction Dc (the surface facing the back of FIG. 3). There is. The child door sealing device 50 is sandwiched between the child door 12 and the parent door 11 when the child door 12 is closed and the handle h2 is in the closed position, and the child door 12 and the parent door 11 Seal between the

  When the watertight door 10 described above is closed to secure the watertightness of the watertight section 8, first, the opening 9 is closed by the parent door 11. At that time, the handle h1 is operated from the open position to the closed position. Thereby, the seal device 16 disposed at the upper edge 14a, the right edge 14b, and the left edge 14c of the outer peripheral portion 14 is sandwiched between the periphery of the parent door 11 and the peripheral edge of the opening 9, and is compressed and deformed. At the same time, the third seal portion 16c is sandwiched between the third seal attachment surface 22 of the lower edge portion 14d and the third seal opposing surface 32 of the watertight partition wall 7 to be compressed and deformed.

  Further, the first seal attachment surface 20 is displaced by the first pressing mechanism 41 described above to press the first seal portion 16a, and the second seal attachment surface 21 is displaced to press the second seal portion 16b. As a result, all of the first seal portion 16a, the second seal portion 16b, and the third seal portion 16c attached to the lower edge portion 14d of the outer peripheral portion 14 are in a state of being compressed and deformed. That is, the gap between the outer peripheral portion 14 of the watertight door 10 and the opening 9 is sealed by the sealing device 16 over the entire circumference of the watertight door 10. The child door 12 may be closed at any timing before and after the parent door 11 is closed.

  Therefore, according to the embodiment described above, the first seal portion 16 a of the seal device 16 is disposed between the first seal attachment surface 20 facing downward and the first seal opposing surface 30 formed at the lower edge of the opening 9. Is caught. Furthermore, the second seal portion 16 b of the seal device 16 is sandwiched between the second seal mounting surface 21 facing the left and right outer sides and the second seal opposing surface 31 formed at the lower edge of the opening 9. That is, the lower edge of the watertight partition wall 7 can be provided with a portion that does not have a surface facing in the horizontal direction, which is the opening direction Do of the watertight door 10. Then, the height at which the lower edge of the opening 9 protrudes from the deck 6 constituting the floor surface can be reduced to about the plate thickness T3 of the horizontal plate portion 37 provided with the first seal opposing surface 30, for example, Even in the case of carrying a heavy load on a carriage or the like, it is possible to easily get over. As a result, it is possible to easily carry in and out heavy items and the like to the watertight section 8.

  Furthermore, by providing the first pressing mechanism 41, the first seal portion 16a disposed between the first seal attachment surface 20 and the first seal opposing surface 30 can be sufficiently compressed and deformed. Further, by providing the second pressing mechanism 42, the second seal portion 16b disposed between the second seal attachment surface 21 and the second seal opposing surface 31 can be sufficiently compressed and deformed. As a result, water tightness between the watertight door 10 and the lower edge of the opening 9 of the watertight bulkhead 7 can be sufficiently ensured.

  Further, the first pressing mechanism 41 and the second pressing mechanism 42 can be accommodated in the accommodation recess 40. Moreover, since the accommodation recessed part 40 is opened in the direction which open | releases the watertight door 10, operation and adjustment of the 1st press mechanism 41 and the 2nd press mechanism 42 can be performed easily. Further, by forming the housing recess 40, it is possible to form the bottom wall 43 and the top wall 47 facing each other and to form the two side walls 45 facing each other, so that the first pressing mechanism 41 and the second pressing mechanism 41 The pressing force by the pressing mechanism 42 can be efficiently applied to the first seal mounting surface 20 and the second seal mounting surface 21 with the opposing walls as a fulcrum.

  Furthermore, while closing the parent door 11, a person can enter and leave the watertight section 8 through the child door 12. In addition, when water that does not reach the lower opening edge of the child door opening 13 is flowing along the floor surface (the lower deck 6), it is possible to allow people to enter and leave the watertight section 8, Water flowing along the surface can be prevented from flowing into the watertight section 8. Furthermore, since a general sealing mechanism can be used as the child door sealing device 50, the procedure at the time of opening and closing can be simplified. Therefore, the child door 12 can be easily opened and closed.

  Further, by providing the first slit 44 and the second slit 46, the first seal attachment surface 20 and the second seal attachment surface 21 can be easily displaced. Therefore, the seal device 16 attached to the first seal attachment surface 20 and the second seal attachment surface 21 can be easily compressed and deformed.

  Furthermore, since the first seal opposing surface 30, the second seal opposing surface 31, and the third seal opposing surface 32 are provided, the seal is formed between the first seal mounting surface 20 and the first seal opposing surface 30, respectively. The device 16 can be stably inserted. Similarly, the seal device 16 can be stably sandwiched between the second seal mounting surface 21 and the second seal opposing surface. Furthermore, the seal device 16 can be sandwiched between the third seal mounting surface 22 and the third seal opposing surface 32. Therefore, the water tightness by the sealing device 16 between the lower edge 14 d of the watertight door 10 and the lower edge of the opening 9 can be improved.

The present invention is not limited to the configuration of the embodiment described above, and design changes can be made without departing from the scope of the invention.
For example, in the embodiment described above, the case where the third seal opposing surface 32 is formed in a planar manner from the first seal opposing surface 30 has been described. However, the surface sandwiching the seal device 16 with the first seal mounting surface 20 and the third seal mounting surface 22 is not limited to a flat surface.

In the embodiment described above, the case where the first slit 44 is formed in the bottom wall 43 of the housing recess 40 and the second slit 46 is formed in the side wall 45 has been described. However, as long as the bottom wall 43 and the side wall 45 can be displaced, the slit may not be provided.
Furthermore, in the embodiment described above, although the case where the watertight door 10 includes the child door 12 and the child door opening 13 has been described, the present invention is also applicable to a watertight door not provided with the child door 12 and the child door opening 13 It is possible.

Further, the first pressing mechanism 41 and the second pressing mechanism 42 may be provided as needed, and may be omitted.
Furthermore, it is not restricted to what opens and closes the watertight door 10 by a hinge.
