Description

The present invention relates to a drain receiving hopper device. More specifically, the present invention relates to a drain receiving hopper device used for confirming drain drain on a ship.

There is a conventional technology described in Patent Document 1 as a hopper device for checking drain exhaustion of a ship.
This hopper device is equipped with a hopper that is connected to a drain pipe that guides the drain, and the hopper is made up of a cylindrical body and has an opening for visually checking when the drain is out, and a lid made of a transparent material can be opened and closed at will. installed.
According to this hopper device, the inside of the hopper can be seen through the transparent member of the opening, so it is possible to check whether the drain is running out. However, in this prior art hopper device, the lid is attached to the side wall of the hopper via a hinge, and the handle is also attached to the lid, so the hinge and handle protrude from the side of the cylindrical hopper. .

The above-mentioned structure in which some parts protrude laterally from the hopper body also poses a problem in other conventional techniques. For example, in a conventional hopper device Z shown in FIG. 7, a lid 103 that swings up and down to open and close is attached to a part of the top plate 102 of a cylindrical hopper body 101 via a hinge 104. On the other hand, the support fitting 106 of the set screw 105 is attached to the side surface of the hopper body 101. When fixing the lid 103, a set screw 105 is hooked onto a locking piece 107 attached to the tip of the lid 103, and the screw is tightened. In this configuration, the set screw 105 and the support fitting 106 protrude outward from the hopper body 101.

As described above, if the cylindrical hopper body 101 has a protrusion on the side surface, there is a problem that the number of man-hours increases in the preliminary outfitting stage of shipbuilding.
Advance outfitting is a method in which individual outfitting items are installed on the ground (inside the factory) in advance, rather than being installed one after another in the tanks, holds, living quarters, and engine room of a ship under construction, or in which the fittings are installed on a large scale. This refers to a method in which items are assembled into units and then loaded onto a ship. Block outfitting, which is a type of advance outfitting, is a method in which each outfitting item is attached to the hull block on the ground (in a factory) before the hull block is mounted on the ship's platform or dock.

In block outfitting, the outfitting work below the deck is difficult in normal rotation, so the work is carried out with the deck D inverted, as shown in Figure 8. In the figure, symbol D indicates the deck, and SP indicates the ship's side shell. The figure is inverted, so the part of the side shell plate SP that narrows toward the bottom of the ship faces upward in the figure, the lower surface of deck D faces upward in the figure, and the upper surface of deck D faces downward in the figure. .
However, in the conventional hopper device Z, since the set screw 105 and the support fittings 106 protrude outward from the hopper body 101, which is a cylinder, the screws 105 and the support fittings 106 are formed on the deck D in an inverted state. It cannot be inserted into the mounting hole from above.

Therefore, as shown on the right side of FIG. 8, there is one worker W2 below the deck D in the inverted state, and that worker W2 inserts the hopper device Z from below, and the worker W1 on the deck holds the deck D in the inverted state. The hopper device Z was positioned from above D (originally the bottom surface of deck D) and temporarily fixed by temporary welding or the like. Thereafter, as shown on the left side of the figure, when the piping P is connected to the hopper device Z, the piping process under the deck is completed.
As described above, the conventional hopper device Z requires two people to attach it to the deck D, so there is a problem in that the number of manufacturing steps increases.

Furthermore, in the conventional hopper device Z, as shown in FIG. 7, the connecting pipe 112 connected to the drain pipe dp was deeply inserted into the hopper body 101. The drain liquid discharged from the connecting pipe 112 hits the inner wall of the tapered lower cylindrical portion 101b of the hopper body 101 and jumps diagonally upward, generating rising pressure and draining from between the lid 103 and the upper end of the hopper body 101. There were times when the liquid leaked. In this case, the top of the deck gets dirty.

Publication No. 61-62218

In view of the above circumstances, it is an object of the present invention to provide a drain receiving hopper device that can be installed by one person, reduces the number of manufacturing steps, and does not cause liquid leakage.

The drain receiving hopper device of the first invention is a hopper device for receiving drain on a ship, and includes a cylindrical hopper body, a flange attached to the bottom of the hopper body, and a flange attached to the upper open end of the hopper body. It is characterized by consisting of a formed top plate and an openable/closeable viewing window formed in a part of the top plate.
In the drain receiving hopper device of a second invention, in the first invention, the viewing window moves reciprocally along an opening formed in the top plate, a slide guide formed around the opening, and the slide guide. It is characterized by consisting of a sliding plate that can be opened and closed by doing so.
In the drain receiving hopper device of a third aspect of the invention, in the first aspect, the viewing window includes an opening formed in the top plate, a plate member formed around the opening, and a top surface of the plate member. It is characterized by comprising a rocking plate that opens and closes by swinging, and a packing interposed between the plate member and the rocking plate.

According to the first invention, since the viewing window is formed in a part of the top plate formed on the upper part of the hopper body, no member protrudes outward from the side surface of the hopper body. Therefore, when attaching the hopper device to the deck that has been inverted due to advance outfitting (block outfitting), it can be temporarily fixed by inserting it into the mounting hole formed in the deck from above, making it possible for one person to do the work. As a result, work efficiency can be significantly improved compared to the conventional method, which required two people to work.
According to the second aspect of the invention, the sliding plate constituting the viewing window does not open even due to the upward flow inside the hopper when receiving drain, so no leakage to the outside occurs.
According to the third invention, since the rocking plate constituting the viewing window has a packing against the internal pressure inside the hopper when receiving drain, it is possible to prevent drain liquid from leaking to the outside.

Next, embodiments of the present invention will be described based on the drawings.
(First embodiment)
The configuration of the hopper device A of the first embodiment will be explained based on FIGS. 1 and 2. FIG. 1 is a sectional view taken along line II in FIG. 2.
Reference numeral 1 designates a cylindrical hopper body, which consists of an upper cylinder part 1a of equal diameter and a tapered lower cylinder part 1b that tapers toward the bottom end. With this configuration, the hopper body 1 can once receive the drain liquid and then discharge it.
A flange 2 is attached to the bottom of the hopper body 1. A discharge pipe (discharge pipe) is attached to this flange 2.

An upper opening of the hopper body 1 is covered with a top plate 3.
A part of the top plate 3 is provided with a viewing window 4 that can be opened and closed. The viewing window 4 includes an opening 5 formed in the top plate 3, slide guides 6 formed on both sides of the opening 5, and a slide plate 7 that reciprocates along the slide guide 6.

The opening 5 is formed in the center of about half the area (the left half in the figure) of the top plate 3 shown in FIG. 2 at a position that allows the slide plate 7 to reciprocate in the radial direction. It is a quadrilateral with an arc shape.
The slide guide 6 consists of guide rods 6a arranged on both sides of the opening 5 and a receiving plate 6b that supports the slide plate 7.

The slide plate 7 is a similar-shaped plate slightly larger than the opening 5, and its shape is such that one side is curved in an arc shape and the remaining three sides are defined by straight lines. A screw 8 that also serves as a knob is attached to the outer end of the slide plate 7. Note that although the slide plate 7 of this embodiment has a substantially rectangular shape, it is not limited to this shape.
When the screw 8 is pinched and the slide plate 7 is moved radially inward, the opening 5 opens, and when the slide plate 7 is moved radially outward, the opening 5 is closed. The radial direction here refers to a direction with the center of the circular top plate 3 as a reference.

An arc-shaped plate member 9 is provided below the opening 5 in the hopper body 1, and a female thread 8a is formed in this plate member 9.
In the hopper device A of this embodiment, parts such as the slide plate 7, the screw 8, and the plate member 9 are provided inside the outer peripheral surface of the hopper body 1, and there are no members that protrude to the outside.

In this viewing window 4, when the screw 8 is screwed into the female thread 8a with the slide plate 7 closed, the slide plate 7 can be held in a state in which it will not open by itself.
When the screw 8 is loosened and the slide plate 7 is moved inward in the radial direction, the inside of the hopper body 1 can be visually checked, so that drain exhaustion can be confirmed.

As shown in FIGS. 1 and 2, four connecting pipes 11 for connecting drain pipes are attached to the top plate 3. As shown in FIGS. The connecting pipe 11 is a short pipe, and has a female thread 11a cut inside. When a drain pipe is connected to this female thread 11a, drain liquid can be received inside the hopper body 1. Connection sources of the drain pipe include an air tank, a fuel oil purifier, a lubricating oil purifier, etc., but these are just examples and there are no particular limitations.

FIG. 3 shows how the hopper device A is used. The drain pipe dp is connected to the connecting pipe 11, and the flange 2 is connected to the discharge pipe P.
Drain liquid led from the drain pipe dp flows in the hopper body 1 as shown by the arrow.

Since the connecting pipe 11 is shorter in length than the conventional connecting pipe 112 shown in FIG. 7, the distance between the vertical and downward flow of the drain liquid is longer, and even when it hits the inner wall of the hopper body 1, the force is weaker. There will be less bounce. Therefore, the amount that flows directly into the discharge pipe P increases.
On the other hand, some drain liquid hits the tapered lower cylindrical portion 1b of the hopper body 1 and bounces upward, but this drain liquid only pushes up the slide plate 7 from below, and no horizontal force is generated, and the slide plate 7 Do not move it in the direction of opening. Therefore, leakage of drain liquid from the hopper body 1 does not occur. Therefore, there is no liquid leakage that occurs in the prior art shown in FIG. 7, and the deck is not contaminated.

The outfitting work of the hopper device A in block outfitting will be explained based on FIG. 6.
As described above, in the hopper device A, there is no member that protrudes outward in the radial direction of the hopper body 1. Both the slide plate 7 and the screw 8 exist in a state where they are retracted radially inward from the outer peripheral surface of the hopper body 1.
Therefore, as shown on the right side of FIG. 6, it can be temporarily fixed by inserting it from above into the mounting hole h formed in the inverted deck D during block outfitting. After the temporary fixing, the hopper device A may be fixed to the deck D by welding or the like, as shown on the left side of FIG. Furthermore, the work of connecting the pipe P can also be done by one person.
In this way, the hopper device A allows the worker W1 to work alone. Therefore, work efficiency can be significantly improved compared to the conventional method where two people worked.

(Second embodiment)
A hopper device B according to a second embodiment will be described based on FIGS. 4 and 5.
The configurations of the hopper body 1, flange 2, top plate 3, and connecting pipe 11 in the hopper device B are the same as those in the hopper device A of the first embodiment, and therefore the description thereof will be omitted. Below, the configuration of the viewing window 14 attached to the opening 5 will be explained.

The viewing window 14 in the hopper device B is configured using a swing plate 17 that opens and closes an opening formed in the top plate 3. Although the swing plate 17 of this embodiment has a semicircular shape, it is not limited to this shape.
The base end of the swing plate 17 is attached with a hinge 18, and the tip swings upward and also swings downward from above. A screw 8 that also serves as a knob is attached to the tip of the swing plate 17. A plate member 19 is formed around the opening, and a female screw hole 9a is formed in the plate member 19. A packing 21 is placed between the swing plate 17 and the plate member 19. The planar shape of the packing 21 is the same as that of the rocking plate 17.

If the screw 8 is loosened and the swing plate 17 is lifted, the inside of the hopper body 1 can be visually checked to confirm whether the drain has run out. By lowering and closing the swing plate 17 and screwing the screws 8 into the female screw holes 9a, the swing plate 17 can be fixed, and the packing 21 can also be fixed.

In the hopper device B as well, since the connecting pipe 11 is short in length, the vertical distance between which the drain liquid flowing downward flows down is long, and even if it hits the inner wall of the hopper body 1, the force is weak and there is less rebound. Therefore, the amount that flows directly into the discharge pipe P increases.
In addition, some drain liquid hits the tapered lower cylindrical portion 1b of the hopper body 1 and bounces upward, but since the rocking plate 17 and the packing 21 are tightened with the screws 8, leakage of the drain liquid to the outside can be prevented. .

The outfitting work of the hopper device B in block outfitting will be explained.
Also in the hopper device B, there is no member that protrudes outward in the radial direction of the hopper body 1. Therefore, it can be temporarily fixed by inserting it from above into the mounting hole h formed in the inverted deck D when outfitting the block.
Therefore, as in the case of the hopper device A, the worker W1 can work alone. Therefore, work efficiency can be significantly improved compared to the conventional method where two people worked.

(Effects common to the first and second embodiments)
The hopper devices A and B according to the present invention can be lighter in weight than the conventional hopper device Z shown in FIG. In the example of the hopper device A, the length (vertical dimension) h of the upper cylinder portion 1a of the hopper body 1 is 100 mm, the diameter d is 165 mm, the total length H is 259 mm, and the weight is 4.7 kg. In the conventional hopper device Z shown in FIG. 7, the length (vertical dimension) h of the upper cylinder part 101a is 225 mm, the total length H of the hopper body 101 including the lower cylinder part 101b is 450 mm, and the weight is 9 kg. It can be seen that it is considerably smaller and lighter than the previous model.
The reason for this reduction in size and weight is that the connecting tube 11 itself is shorter and lighter than the conventional inner tube 112, and the amount of insertion of the connecting tube 11 into the hopper body 1 is This is because the length (vertical dimension) of the hopper body 1 can also be shortened since it is shorter than the insertion amount of the conventional inner tube 112.

The drain receiving hopper device of the present invention can be used on any type of ship.
