Description

Technical Field

[0001] This utility model relates to the field of lifeboat technology, and in particular to a lifeboat fuel tank. Background Technology

[0002] A lifeboat is a small, specialized lifeboat installed on a ship for rescuing crew members in the event of a shipwreck. It is propelled by oars, sails, or motors. Lifeboats are typically equipped with air tanks to ensure sufficient buoyancy even after flooding, guaranteeing the safety of the lifeboat and its crew. Lifeboats on ocean-going vessels also carry a certain amount of fresh water, food, and supplies. The fuel tanks of lifeboats must be large enough to operate continuously for 24 hours.

[0003] Most existing fuel tanks are single-box structures with simple structures and limited functions, serving only to store fuel. It is inevitable that lifeboats will shake during use. When the fuel tank is not full, the shaking will cause the fuel inside to slosh around. Since the fuel tank is not full, the fuel pump may not be able to draw fuel, affecting the use of the lifeboat. Utility Model Content

[0004] Therefore, it is necessary to provide a lifeboat fuel tank to address the problem that shaking can cause the oil in the tank to slosh around and prevent the oil pump from drawing oil.

[0005] A lifeboat fuel tank includes: a fuel tank body, wherein an inhibition mechanism is provided inside the fuel tank body to reduce the sloshing of fuel and maintain stable fuel supply; the inhibition mechanism includes vertical plates evenly distributed inside the fuel tank body, and through holes are provided on the vertical plates.

[0006] In one embodiment, the bottom of the tank body is provided with a bevel, and the bottom of each vertical plate is in contact with the top of the bevel; In one embodiment, the suppression mechanism further includes a partition and a horizontal plate arranged perpendicular to the vertical plate, and the horizontal plate has an oil return groove. In one embodiment, the horizontal plate is parallel to the inclined side, the oil return groove is disposed on the surface of the horizontal plate and is attached to the position of the vertical plate, and the oil return groove penetrates the surface of the horizontal plate; In one embodiment, a protective shell is provided outside the fuel tank body, and a buffer cavity is provided between the fuel tank body and the protective shell, and the buffer cavity is filled with epoxy resin. In one embodiment, both the inner wall of the tank body and the surface of the suppression mechanism are provided with an anti-corrosion coating; In one embodiment, the outer surface of the protective shell is provided with an arc-shaped edge; In one embodiment, the protective shell is configured as a polyethylene shell. Beneficial effects

[0007] A vertical plate is installed to divide the space inside the fuel tank into multiple small spaces. When the fuel inside the tank sloshes, the vertical plate blocks the sloshing of the fuel, reducing the sloshing and causing the fuel to move within specific small spaces. This reduces the distance the fuel is displaced. The bottom of the fuel tank is equipped with a sloping edge, which, under the action of gravity, causes the fuel to move to the lowest point, allowing the fuel to quickly return to the bottom of the fuel tank and preventing power interruption caused by the fuel pump not being able to draw enough fuel.

[0008] A protective shell is installed to protect the fuel tank body and improve its impact resistance. A buffer chamber is also included, and a double-wall design is used to prevent fuel leakage and improve the safety of the fuel tank. Attached Figure Description

[0017] The following is combined Figures 1-4 This invention describes the fuel tank for a lifeboat.

[0018] In one embodiment, a lifeboat fuel tank includes: a fuel tank body 100, and a suppression mechanism 200 is provided inside the fuel tank body 100 to reduce the sloshing of the fuel and maintain stable fuel supply. The suppression mechanism 200 includes vertical plates 211 evenly distributed inside the fuel tank body 100, and through holes 212 are provided on the vertical plates 211.

[0019] like Figure 2 and Figure 3As shown, the suppression mechanism 200 also includes a partition 214 and a horizontal plate 210 arranged perpendicularly to the vertical plate 211, and the horizontal plate 210 is provided with an oil return groove 213.

[0020] In this embodiment, the oil extraction pipe is located at the lowest point on the right side of the bottom of the oil tank body 100, and a filter is installed on the oil extraction pipe. Oil is drawn from the oil tank body 100 by an oil pump to supply fuel to the lifeboat engine. During normal lifeboat operation, bumps and jolts occur. The vertical plate 211 divides the space inside the oil tank body 100 into several small spaces, each connected by a through-hole 212. During bumps and jolts, oil in each small space can only enter other spaces through the through-hole 212, thus reducing oil flow. The partition plate 214 and the horizontal plate 210 further divide the space, reducing large-scale swaying caused by inertia and preventing concentrated impact on a single point.

[0021] It should be noted that the fuel tank body 100 is equipped with existing fuel tank structures such as a filler neck, fuel tank cap, fuel outlet, and fuel return port, which will not be described in detail here. The fuel tank body 100 is installed at the rear or midsection of the lifeboat, close to the engine and propeller, to shorten the fuel line and improve fuel supply efficiency. The protective shell 300 is equipped with mounting blocks with mounting holes. The protective shell 300 is installed in the required position by fixing bolts and mounting blocks, thereby completing the installation of the fuel tank body 100. The exterior of the protective shell 300 is covered with fire-resistant material to isolate the protective shell 300 and prevent fuel leakage or fire caused by heat.

[0022] like Figure 1 and Figure 4 As shown, the bottom of the fuel tank body 100 is provided with a beveled edge 110, and the bottom of each vertical plate 211 is attached to the top of the beveled edge 110.

[0023] In this embodiment, the inclined side 110 is designed to facilitate the flow of oil to the lowest point inside the oil tank body 100 under the action of gravity, which is convenient for the oil pump to draw it out.

[0024] like Figure 3 and Figure 4 As shown, the horizontal plate 210 is parallel to the inclined side 110, and the oil return groove 213 is set on the surface of the horizontal plate 210 and is attached to the position of the vertical plate 211. The oil return groove 213 penetrates the surface of the horizontal plate 210.

[0025] In this embodiment, the oil return groove 213 and the through hole 212 are provided to allow the oil to flow within the oil tank body 100. The oil in each small space can flow into the lowest point of the oil tank body 100 through the oil return groove 213 and the through hole 212.

[0026] A protective shell 300 is provided outside the fuel tank body 100, and a buffer cavity 310 is provided between the fuel tank body 100 and the protective shell 300, the buffer cavity 310 being filled with epoxy resin. The inner wall of the fuel tank body 100 and the surface of the suppression mechanism 200 are both provided with an anti-corrosion coating. The outer surface of the protective shell 300 has a curved edge. The protective shell 300 is made of polyethylene.

[0027] In this embodiment, the fuel tank body 100 is protected by a protective shell 300, which improves the protective capacity of the fuel tank body 100. The buffer cavity 310 is filled with epoxy resin, which is resistant to chemical corrosion, has high structural strength, and improves the impact resistance of the fuel tank body 100. The polyethylene shell is corrosion-resistant, easy to mold, and lightweight, reducing the weight of the fuel tank and increasing the load-bearing capacity of the lifeboat.

[0028] Working principle: The protective shell 300 is installed inside the lifeboat. The fuel tank body 100 is protected by the protective shell 300 and the packing inside the buffer chamber 310. When the lifeboat is sailing, the fuel in the fuel tank body 100 will slosh. The horizontal plate 210, the partition plate 214, and the vertical plate 211 divide the fuel tank body 100 into several spaces. These spaces are connected by through holes 212, return oil grooves 213, and gaps between the partition plate 214 and the inclined side 110. This restricts the flow of fuel from one space to another, thereby reducing fuel sloshing.

[0029] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0030] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
