Description

[Technical Field]

[0001] The present invention relates to a leakage prevention device for liquids such as oil. [Background technology]

[0002] BACKGROUND ART As a technique for preventing liquid leakage from ships, various structures and devices for preventing leakage of fuel oil, lubricating oil, and the like have been proposed. These measures are primarily designed to prevent liquids on board from leaking into the ocean in the event of external damage, by incorporating innovations into the hull structure, and are considered important from the perspective of environmental protection and ensuring safety.

[0003] In particular, in recent years, large ships such as bulk carriers and tankers have adopted structures that reduce the risk of leakage in the event of damage to fuel oil tanks, and for example, double hull structures and the placement of buffer tanks have become widely used. Furthermore, a technology has been developed that prevents direct leakage by providing a predetermined space between the outer and inner plates of the hull and placing a tank in that space.

[0004] As prior art, Patent Document 1 discloses a hull structure for a bulk carrier in which a fuel oil tank is configured between the outer and inner side plates of the ship, and the double structure prevents fuel leakage in the event of damage to the outer plate. This is intended to prevent leakage through structural barriers. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2005-231528 Summary of the Invention [Problem to be solved by the invention]

[0006] On the other hand, unlike the structural measures mentioned above, in actual offshore work environments, measures to prevent liquid leakage from drainage channels and drainage outlets (scuppers) installed on the hull deck are also an important issue. In particular, on ships and other vessels that refuel at sea, gasoline and other liquids can splash back onto the deck when fuel is being injected, and it is necessary to prevent this liquid from leaking into the ocean through drainage channels or drainage outlets.

[0007] For example, a typical ship has more than 30 drainage ports, each with a different shape and size, making it difficult to apply a general-purpose sealing method that provides a high level of airtightness. For this reason, conventional methods have been to stack sandbags or use silicone sealing plates.

[0008] However, sandbags are heavy and inconvenient to carry, and they are difficult to set up and remove quickly. Furthermore, the silicone plate does not have sufficient sealing ability with the painted surface of the deck or with uneven shapes, making it difficult to completely prevent liquid leakage. Furthermore, it is extremely difficult to ensure high sealing and leak prevention performance with a single sealing device for the various shapes and widths of drainage channels and drainage outlets, and the development of practical countermeasures was required.

[0009] The present invention has been made in consideration of the above-described circumstances, and its object is to provide a highly versatile leakage prevention device that has a simple configuration, improves sealing properties, and effectively suppresses liquid leakage.

DETAILED DESCRIPTION OF THE INVENTION

[0022] Hereinafter, a leakage prevention device according to an embodiment of the present invention will be described with reference to FIGS. The following embodiment is an example of the present invention, and the present invention is not limited to the following embodiment. In these figures, the symbol X indicates the leakage prevention device according to this embodiment.

[0023] <Embodiment 1> The leakage prevention device X according to the first embodiment will be described below with reference to FIGS. For convenience of explanation, the x-axis direction in FIGS. 1 and 2 will be referred to as the left-right direction, and the z-axis direction as the up-down direction.

[0024] <<Configuration>> As shown in Figure 1, the leakage prevention device X prevents leakage of liquid and comprises a leakage prevention device main body 1 formed from a soft material having elasticity as a whole, and a substantially block-shaped auxiliary body 2 provided separately from the leakage prevention device main body 1.

[0025] The leakage prevention device main body 1 comprises a first component 11 that forms a contact surface A that contacts an installation surface P (see Figure 2) near a liquid outlet E (see Figure 2), and a second component 12 that is laminated integrally with the first component 11. As the material (soft material) forming the leakage prevention device main body 1, a flexible material that can be elastically deformed in a room temperature environment is preferably used, such as silicone rubber, styrene-based elastomer, polyurethane, polyethylene, polypropylene, ethylene vinyl acetate copolymer (EVA), gel resin, or a resin composition containing these as its main component.

[0026] The first component 11 and the second component 12 are each configured as an approximately rectangular parallelepiped having approximately the same length, cross-sectional area, and cross-sectional shape, and by stacking them together, the leakage prevention device main body 1 as a whole has an approximately rectangular parallelepiped shape. Moreover, both the first component 11 and the second component 12 are configured to be substantially transparent. Note that "substantially transparent" means a translucency that allows light to pass through and allows the outline and position of an object placed on the backside or inside to be visible to some extent by the human eye.

[0027] The first component 11 has a side (one long side) facing the joint surface with the second component 12 configured as an abutment surface A, and the abutment surface A has flexibility that allows it to deform to follow the surface shape of the installation surface P. In addition, each side surface of the first component 11, including the contact surface A, has adhesiveness.

[0028] The side surfaces of the second structure 12 do not have adhesive properties.

[0029] In this specification, "having adhesiveness" means that when the leakage prevention device X comes into contact with an object (such as the deck of a ship) during use, it can be easily attached by its own weight or by manual pressure, and can maintain its position for a certain period of time. The adhesiveness also means that the tape can be easily removed and reused after installation, and has adhesive strength sufficient to allow repeated installation and removal in a practical manner.

[0030] In this embodiment, the auxiliary body 2 has a cross-sectional area and cross-sectional shape that are approximately the same as the left and right side surfaces of the leakage prevention device main body 1, and is configured in an approximately rectangular shape with a thickness that is approximately the same as the vertical thickness (height) of the leakage prevention device main body 1. In addition, like the leakage prevention device main body 1, the auxiliary body 2 is formed from a soft material that has elasticity overall, and each of its sides is adhesive, so that it can adhere to the side adjacent to the contact surface A. Furthermore, the entire auxiliary body 2 is constructed to be substantially transparent. The material preferably used for the auxiliary body 2 is the same as that for the leakage prevention device main body 1.

[0031] <<Usage>> The leakage prevention device X having the above-described configuration is used in the manner shown in, for example, FIGS. 2 and 3 show a drainage channel D that is provided on the outer edge of the ship's deck and constitutes an outlet E, and illustrate the use of a leakage prevention device X to prevent leakage of fuel oil, lubricating oil, etc. from the drainage channel D. The drainage channel D has a left-right width defined by a side wall w that stands upright from the deck, and is configured to allow drainage from the deck through the drainage channel D into the sea.

[0032] In more detail, as shown in Figure 2, the user places the leakage prevention device main body 1 in the drainage channel D by installing the leakage prevention device main body 1 on the deck (installation surface P) that constitutes the drainage channel D so that it extends across the left and right width defined by the side wall w.

[0033] At this time, as shown in particular in Figure 2(b), the contact surface A, which is the bottom surface (lower side surface) of the leakage prevention device main body 1 (first component 11), deforms and adheres to the surface shape of the installation surface P due to its own weight, thereby sealing the gap between the leakage prevention device main body 1 and the installation surface P. In addition, the user can abut and adhere the left and right ends of the long side of the leakage prevention device main body 1 (first component 11) adjacent to the abutment surface A to each side wall w, thereby sealing the gap between the leakage prevention device main body 1 and each side wall w.

[0034] In addition, the user can use the auxiliary body 2 to achieve the usage mode shown in FIG.

[0035] That is, as shown in FIG. 3(a), the user can freely extend the left and right width that can be accommodated by the leakage prevention device X by adhering two auxiliary bodies 2 to the left and right sides of the leakage prevention device main body 1. At this time, by adhering each auxiliary body 2 to each side wall w, the sealing performance can be improved.

[0036] Furthermore, as shown in FIG. 3(b), the user can arbitrarily extend the height that can be accommodated by the leakage prevention device X by adhering an auxiliary body 2 to the upper side of the leakage prevention device main body 1 (second component 12). The auxiliary body 2 shown in FIG. 3(b) is a structure having substantially the same shape and size as the leakage prevention device main body 1.

[0037] <<Effects>> By using the above-mentioned method, the leakage prevention device main body 1 is interposed in the drainage channel D, blocking the flow path from the deck to the outlet E, thereby preventing leakage of fuel oil, lubricating oil, etc. through the drainage channel D.

[0038] Here, due to the flexibility and adhesiveness of the contact surface A, sealing performance with respect to the installation surface P can be easily ensured, and since the surface of the second component 12 does not have adhesiveness, the second component 12 can function as a gripping portion, making it easy to handle, such as transport.

[0039] Furthermore, since the entire leak prevention device body 1 is made of a soft material with elasticity, it can flexibly change its shape to suit the surrounding environment of the installation location, ensuring sealing performance, thereby improving versatility.

[0040] Furthermore, since both the first component 11 and the second component 12 are configured to be substantially transparent, the presence or absence of leakage and the installation position can be visually confirmed, improving workability.

[0041] Furthermore, since the leakage prevention device main body 1 has a generally rectangular parallelepiped shape as a whole, it can be suitably used to prevent leakage into the drainage channel D.

[0042] Furthermore, since each side surface of the first component 11 has adhesiveness, the first component 11 can be adhered to each side wall w, and the sealing performance in preventing leakage into the drainage channel D is improved.

[0043] <Embodiment 2> The leakage prevention device X according to the second embodiment will be described below with reference to FIGS. In this embodiment, the same components as those in the first embodiment are denoted by the same reference numerals and the description thereof will be simplified.

[0044] <<Configuration>> As shown in FIG. 4, the leakage prevention device X includes a leakage prevention device main body 1 formed entirely from a soft material having elasticity. FIG. 4(b) is a cross-sectional view taken along the line PP' in FIG. 4(a).

[0045] As in embodiment 1, the leakage prevention device main body 1 comprises a first component 11 that forms a contact surface A that contacts an installation surface P (see Figure 5) near the liquid outlet E (see Figure 5), and a second component 12 that is integrally laminated on the first component 11.

[0046] The first component 11 and the second component 12 are each configured as an approximately cylindrical body having approximately the same outer diameter and inner diameter, and by stacking them integrally and coaxially, the leakage prevention device main body 1 has an approximately cylindrical shape as a whole. Moreover, the first structure 11 and the second structure 12 are both configured to be substantially transparent, as in the first embodiment, and the materials that are preferably used are also the same as in the first embodiment.

[0047] As in embodiment 1, the side surface (bottom surface) of the first component 11 opposite the joining surface with the second component 12 is configured as a contact surface A, and the contact surface A has flexibility that allows it to deform to follow the surface shape of the installation surface P. Furthermore, the contact surface A and the outer surface constituting the first structure 11 have adhesiveness, similar to the first embodiment.

[0048] The second component 12 is a cylindrical body with a bottom, and the top surface of the leakage prevention device main body 1 is closed by this. Similarly to the first embodiment, the bottom surface and outer surface of the second structure 12 do not have adhesiveness.

[0049] <<Usage>> The leakage prevention device X having the above-described configuration is used, for example, in a manner as shown in FIG. Figure 5 shows a drain outlet (scupper) S that constitutes an outlet E installed on the deck of a ship, and shows an embodiment in which a leakage prevention device X is used to prevent leakage of fuel oil, lubricating oil, etc. from the drain outlet S.

[0050] In more detail, the user places the leak prevention device main body 1 over the drain outlet S so that the drain outlet S fits inside it, as shown in Figure 5, and installs the leak prevention device main body 1 on the deck (installation surface P), thereby achieving the state shown in Figures 5(a) to (b).

[0051] At this time, as in embodiment 1, the contact surface A, which is the bottom surface of the leakage prevention device main body 1 (first component 11), deforms and adheres to the surface shape of the installation surface P due to its own weight, thereby sealing the gap between the leakage prevention device main body 1 and the installation surface P.

[0052] <<Effects>> By using the above method, the area around the drain outlet S (side and upper sides) is sealed, blocking the flow path from the deck to the outlet E, preventing leakage of fuel oil, lubricating oil, etc. through the drain outlet S.

[0053] Here, this embodiment has the same effects as the first embodiment in terms of ease of ensuring sealing performance, ease of handling such as transportation, and improved workability.

[0054] Furthermore, since the leakage prevention device main body 1 has a generally cylindrical shape as a whole, it can be suitably used to prevent leakage from the drain outlet S.

[0055] Furthermore, since the second component 12 is a cylindrical body with a bottom, it is possible to prevent dust from entering the drain outlet S from above.

[0056] <Example of change> The shapes and dimensions of the components shown in the above-described embodiments are merely examples and can be modified in various ways based on design requirements, etc.

[0057] For example, in each embodiment, the adhesiveness of the surface of the second component 12 may be configured to be lower than that of the contact surface A, and may have adhesiveness that is sufficient to function as a gripping portion without sticking strongly to the user's hand.

[0058] Furthermore, in each embodiment, it is not necessary for each side surface of the first structure 11 to be adhesive, and only the contact surface A may be adhesive.

[0059] Furthermore, in each embodiment, the second structure 12 does not necessarily have to be substantially transparent, and it is sufficient if only the first structure 11 is substantially transparent.

[0060] Furthermore, in each embodiment, the thickness of the first structure 11 and the second structure 12 does not need to be the same, and can be changed as appropriate as long as the adhesive and gripping functionality is not lost.

[0061] Furthermore, in embodiment 1, the number of auxiliary bodies 2 is not limited to two as shown in Figure 2(a) and can be any number, and their shape can be any shape, such as a cylinder, triangular prism, or cone, as long as they are block-shaped, as shown in the variations in Figure 2(b).

[0062] Furthermore, in the first embodiment, the auxiliary body 2 may be configured so that only one or two sides are adhesive, or may be a laminated body that forms a grip portion, like the leakage prevention device main body 1.

[0063] Furthermore, in embodiment 1, the manner in which the auxiliary body 2 is connected to the leakage prevention device main body 1 is not limited to that shown in Figures 2(a) and (b), and another auxiliary body 2 may be adhered to the auxiliary body 2, and the auxiliary body 2 can be expanded in both the left-right and up-down directions.

[0064] Furthermore, in embodiment 2, the second component 12 does not need to be cylindrical with a bottom, and may be a simple cylindrical body, which allows multiple leakage prevention device bodies 1 to be stacked upward.

[0065] Furthermore, in the second embodiment, the overall shape of the leakage prevention device main body 1 may be a square or triangular cylinder, etc., as long as it is cylindrical.

[0066] Furthermore, in the second embodiment, similarly to the first embodiment, an auxiliary body 2 configured separately from the leakage prevention device main body 1 may be provided.

[0067] Additionally, in each of the above embodiments, the leakage prevention device X is applied to a drainage channel or drain outlet installed on the deck of a ship, but the present invention is not limited to this. For example, it can be similarly applied to drainage channels installed on the rooftops and balconies of buildings, or to drainage outlets on land at factory floors, temporary work sites, parking lots, and car washes.

[0068] The word "abbreviated" in the application documents is a concept that means that the shape that follows has been chamfered or rounded, and also includes elements that make up the shape that have been deformed or changed in length within the scope that does not impede the purpose of the shape.
