Description

Technical Field

[0001] This utility model relates to the field of marine technology, and in particular to a fluid intrusion protection device. Background Technology

[0002] In the marine industry, fuel tanks are usually used with vent caps; the automatic closing function of the vent cap is accomplished by the float or buoy inside it; when the external environment is harsh, such as seawater or rainwater entering the vent cap and not being able to drain in time, the float or buoy will be lifted; once the float or buoy is lifted, water flow cannot enter the vent pipe, thus effectively preventing the possibility of water entering the fuel tank.

[0003] However, if the buoy gets stuck or the seals age, or if the ship is involved in an accident or severe weather, the waterproofing effect will decrease, and water will rush in from the vent cap, which will cause water to enter the oil tank. Summary of the Invention

[0004] The purpose of this utility model is to solve the technical problems in the prior art where the buoyancy cap of the ship's oil tank gets stuck or the sealing ring ages, or the waterproof effect decreases when the ship is involved in an accident or severe weather. This application adds a water-proof device below the ventancy cap, which can drain the water that flows into the ventancy cap when the waterproof effect of the ventancy cap decreases, thus preventing water from entering the oil tank and ensuring the safety of the ship's navigation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a fluid intrusion protection device, comprising: a vent cap, wherein a first vent pipe is provided at the bottom of the vent cap; a water-proof device is provided below the first vent pipe, wherein the vent pipe extends into the water-proof device; the water-proof device is used to drain the water inside the vent cap when water enters the vent cap.

[0006] Furthermore, the water-proof device includes a water storage tank, with a first vent pipe extending into the water storage tank; a drain pipe is provided at the bottom of the water storage tank, and the drain pipe is connected to the inside of the water storage tank; the water in the vent cap can be drained into the water storage tank and then discharged through the drain pipe.

[0007] Furthermore, an oil baffle is installed around the perimeter of the deck area below the drain pipe to intercept the water discharged from the drain pipe. A floor drain is installed at the bottom of the deck area below the drain pipe to drain the water intercepted by the oil baffle.

[0008] Furthermore, the interior of the water tank is connected to the oil tank via a second vent pipe, which allows for ventilation of the oil tank.

[0009] Furthermore, the bottom of the first vent pipe is lower than the connection port between the second vent pipe and the water tank to prevent water in the first vent pipe from flowing into the oil tank through the connection port.

[0010] Furthermore, the drain pipe is a horizontal S-shape, and the outlet of the drain pipe is lower than the top of the oil-blocking flat iron, which facilitates the oil-blocking flat iron to intercept moisture.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. This utility model provides a fluid intrusion protection device. Traditionally, a single vent pipe connects the vent pipe on the oil tank directly to the vent cap. When the vent cap's float gets stuck, the sealing ring ages, or when the ship is involved in an accident or severe weather, the waterproofing effect decreases, allowing water to seep in through the vent cap and into the oil tank. This application adds a water-proof device between the vent cap and the oil tank. When the waterproofing effect of the vent cap decreases, water enters the water storage tank through the vent cap but not into the oil tank. The water in the water storage tank is then drained to the floor drain through the drain pipe. The oil tank is connected to the water storage tank through a first vent pipe, and the top of the water storage tank is connected to the vent cap through the first vent pipe. This also achieves the same ventilation effect in the oil tank, thus preventing water ingress when the waterproofing effect of the vent cap decreases, ensuring the ship's navigation safety, and the ventilation effect of the oil tank remains unaffected.

[0013] 2. The fluid intrusion protection device provided by this utility model is such that when water is discharged from the first vent pipe into the water tank, it passes over the connection port between the second vent pipe and the water tank, thus preventing water from entering the oil tank through the connection port.

[0019] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. In addition, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other. Example

[0021] Please see Figures 1 to 2 This utility model provides a fluid intrusion protection device, comprising: a vent cap 1, with a first vent pipe 2 at the bottom of the vent cap 1; a water ingress prevention device below the first vent pipe 2, the vent pipe extending into the water ingress prevention device; the water ingress prevention device is used to drain water from the vent cap 1 when water enters the vent cap 1; the water ingress prevention device includes a water storage tank 3, with the first vent pipe 2 extending into the water storage tank 3; a drain pipe 4 at the bottom of the water storage tank 3, the drain pipe 4 communicating with the interior of the water storage tank 3; an oil baffle flat iron 8 arranged around the area below the drain pipe 4; a floor drain 7 arranged at the bottom of the area below the drain pipe 4 for draining water intercepted by the oil baffle flat iron 8; the interior of the water storage tank 3 is connected to an oil tank 6 via a second vent pipe 5, allowing ventilation of the oil tank 6 through the second vent pipe 5.

[0022] The side of the water tank 3 can be connected to the side wall of the compartment via a connecting rod to fix the water tank. In the traditional single venting system, the venting pipe on the oil tank 6 is directly connected to the vent cap 1. When the float of the vent cap 1 is stuck or the sealing ring ages, or when the ship is involved in an accident or severe weather, the waterproofing effect will decrease, and water will rush in from the vent cap 1 and enter the oil tank 6. However, this application adds a water-proof device between the vent cap 1 and the oil tank 6. When the waterproofing effect of the vent cap 1 decreases, water will enter the water tank 3 through the vent cap 1 and will not enter the oil tank 6. The water in the water tank 3 will then be discharged to the floor drain 7 through the drain pipe 4. The oil tank 6 is connected to the water tank 3 through the first venting pipe 2, and the top of the water tank 3 is connected to the vent cap 1 through the first venting pipe 2. In this way, the venting effect in the oil tank 6 can also be achieved, which can prevent water from entering when the waterproofing effect of the vent cap 1 decreases, thereby ensuring the safe navigation of the ship. The venting effect of the oil tank 6 is not affected at all. Example

[0023] Unlike the above embodiments, in this embodiment, the bottom of the first vent pipe 2 is lower than the connection port between the second vent pipe 5 and the water storage tank 3; the discharge pipe 4 is a horizontal S-shape, so that the discharge pipe 4 is made in the form of a water trap, which can retain water in the water trap, so that gas will not overflow through the discharge pipe when the vent pipe is venting, thus ensuring that the venting effect is not affected; the outlet of the discharge pipe 4 is lower than the top of the oil catch flat iron 7.

[0024] The bottom of the first vent pipe 2 is lower than the connection port between the second vent pipe 5 and the water storage tank 3, so that when water is discharged from the first vent pipe 2 into the water storage tank 3, it passes over the connection port between the second vent pipe 5 and the water storage tank 3, preventing water from entering the oil tank 6 through the connection port; the oil baffle flat iron 8 encloses a drainage space in the side area of ​​the oil tank 6, and water flows into this space and is discharged from the floor drain 7. The outlet of the drain pipe 4 is lower than the top of the oil baffle flat iron 8, which can reduce the possibility of water splashing out and make the oil baffle flat iron 8 better intercept.

[0025] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
