Description

Technical Field

[0001] This utility model relates to the field of marine fuel system technology, specifically to a marine fuel tank with automatic drainage function. Background Technology

[0002] Fuel tanks are key oil storage devices in marine power systems. Their main function is to store purified fuel oil and provide readily available fuel oil for marine main engines, generators, boilers, and other equipment.

[0003] During storage and transportation, fuel oil is susceptible to moisture contamination due to various reasons, such as rainwater seepage caused by poor sealing of fuel tanks, water ingress due to fuel oil separator malfunctions, or condensation generated during fuel oil storage. Excessive water content in fuel oil can lead to malfunctions such as flameout in the ship's main and auxiliary engines, boilers, and other equipment, seriously affecting navigational safety and normal operations. Currently, ship fuel oil systems lack effective water content monitoring and automatic drainage functions, typically relying on manual periodic checks and drainage. This method is not only inefficient but also makes it difficult to ensure timely detection and handling of excessive water content issues, posing significant safety hazards. Utility Model Content

[0004] The purpose of this invention is to provide a ship fuel tank with an automatic drainage function to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A ship fuel tank with automatic drainage function includes a support leg, an automatic drainage mechanism is provided on the top of the support leg, and a waste liquid collection mechanism is provided on the outer wall of the support leg.

[0007] The automatic drainage mechanism includes a closed base plate, which is fixedly installed on the top of the support leg. An oil storage tank is fixedly installed on the top of the closed base plate. A through groove is opened on the top of the closed base plate. A monitoring box located below the through groove is fixedly connected to the bottom of the closed base plate. A moisture content sensor is fixedly installed on the side wall of the monitoring box. The measuring end of the moisture content sensor extends into the inner cavity of the monitoring box. A controller is fixedly installed on the side wall of the monitoring box. A residual discharge valve is fixedly connected to the bottom of the monitoring box.

[0008] Preferably, the top of the oil storage tank is fixedly connected to an exhaust port, the top of the oil storage tank is fixedly connected to an oil return port located to the right of the exhaust port, and the top of the oil storage tank is fixedly connected to an oil filling port located to the left of the exhaust port.

[0009] Preferably, a level gauge is fixedly connected to the front of the oil storage tank, and an oil outlet is fixedly connected to the front of the oil storage tank.

[0010] Preferably, the waste liquid collection mechanism includes an inner support frame, which is fixedly installed on the outer wall inside the support leg, and a sliding groove seat is fixedly installed on the side of the inner support frame away from the support leg.

[0011] Preferably, a movable base plate is detachably connected to the inner wall of the slide bar seat, and a locking bolt is threadedly connected to the top of the movable base plate, with the threaded end of the locking bolt movably abutting against the top of the slide bar seat.

[0012] Preferably, a collection chamber is fixedly installed on the top of the movable base plate, a valve is fixedly connected to the front of the collection chamber, and a receiving cylinder is fixedly connected to the top of the collection chamber.

[0023] The present invention will be further described in detail below with reference to embodiments:

[0024] like Figures 1-6 As shown, this utility model provides a ship fuel tank with automatic drainage function, including a support leg 1, an automatic drainage mechanism 2 is provided on the top of the support leg 1, and a waste liquid collection mechanism 3 is provided on the outer wall of the support leg 1.

[0025] The automatic drainage mechanism 2 includes a closed base plate 21, which is fixedly installed on the top of the support leg 1. An oil storage tank 22 is fixedly installed on the top of the closed base plate 21. A through groove 28 is formed on the top of the closed base plate 21. A monitoring box 29 located below the through groove 28 is fixedly connected to the bottom of the closed base plate 21. A moisture content sensor 291 is fixedly installed on the side wall of the monitoring box 29, with its measuring end extending into the inner cavity of the monitoring box 29. A controller 292 is fixedly installed on the side wall of the monitoring box 29, and a residual discharge valve 293 is fixedly connected to the bottom of the monitoring box 29. The moisture content sensor 291 employs... High-precision capacitive or radio frequency sensors can accurately detect minute changes in the water content of fuel and convert the water content data into an electrical signal output. The position design of the water content sensor 291 ensures that the area with the highest water content can be monitored. The drain valve 293 uses an electric or pneumatic valve, which has good sealing performance and fast response capability, ensuring the accuracy and timeliness of the draining operation. The water content data monitored by the water content sensor 291 is fed back to the controller 292, where a fuel water content threshold is preset. For example, when the water content reaches 5% (which can be adjusted according to actual conditions), it is considered... If the water content is too high, the residual water release valve 293 opens. When the water content drops to a normal range, such as below 3%, the controller 292 sends a closing signal, and the residual water release valve 293 closes, achieving automatic drainage. This avoids the inefficiency of manual periodic checks and manual drainage, ensuring that the water content of the fuel in the ship's fuel system remains within a safe range, preventing equipment shutdown due to excessive water content, and ensuring the safe and stable operation of the ship. It is worth noting that the water content sensor 291, controller 292, and residual water release valve 293 in this solution are commercially available devices that can be purchased by those skilled in the art, and their use is not discussed in this document. The structural improvements are made so that those skilled in the art are familiar with and proficient in their working principles based on their professional knowledge. Therefore, this paper will not elaborate on these aspects. Furthermore, this solution aims to protect the physical structure, but does not protect the circuit and software control. The proposed processing circuit is merely a supplementary explanation of the feasibility and authenticity of this utility model. This utility model does not seek protection for the algorithm and circuit technology. It is worth emphasizing that although this solution does not elaborate on the electronic control program, those skilled in the art can be familiar with and apply it based on their professional knowledge.

[0026] Furthermore, such as Figure 3As shown, an exhaust port 23 is fixedly connected to the top of the oil storage tank 22, an oil return port 24 located to the right of the exhaust port 23 is fixedly connected to the top of the oil storage tank 22, an oil filling port 25 located to the left of the exhaust port 23 is fixedly connected to the top of the oil storage tank 22, a level gauge 26 is fixedly connected to the front of the oil storage tank 22, and an oil outlet 27 is fixedly connected to the front of the oil storage tank 22. The cavity formed by the oil storage tank 22 and the closed bottom plate 21 can store marine fuel oil, and fuel oil can be taken out from the oil outlet 27 and added from the oil filling port 25. The design of the level gauge 26 makes it convenient for users to observe the fuel oil level in the cavity of the oil storage tank 22.

[0027] Furthermore, such as Figure 5 , Figure 6 As shown, the waste liquid collection mechanism 3 includes an inner support frame 31, which is fixedly installed on the outer wall inside the support leg 1. A chute seat 32 is fixedly installed on the side of the inner support frame 31 away from the support leg 1. A movable base plate 33 is detachably connected to the inner wall of the chute seat 32. A locking bolt 34 is threadedly connected to the top of the movable base plate 33. The threaded end of the locking bolt 34 movably abuts against the top of the chute seat 32. A collection chamber 35 is fixedly installed on the top of the movable base plate 33. A valve is fixedly connected to the front of the collection chamber 35. The top of the collection chamber 35 is fixedly connected to the door 36 and the receiving tube 37. The collection chamber 35 is designed to store waste liquid. By opening the valve 36, the waste liquid inside the collection chamber 35 can be discharged. When installing the collection chamber 35, the movable base plate 33 is inserted into the slide bar seat 32, and then the locking bolt 34 is tightened. When disassembling and cleaning the collection chamber 35, the locking bolt 34 is loosened, and then the movable base plate 33 is pulled out from the slide bar seat 32, thus completing the disassembly of the collection chamber 35.

[0028] Furthermore, such as Figure 5 , Figure 6 As shown, an inner support rod 371 is fixedly installed on the inner wall of the receiving cylinder 37, and a conical cover 372 located below the inner support rod 371 is fixedly installed on the inner wall of the receiving cylinder 37. An elastic rope 373 is fixedly connected to the bottom of the inner support rod 371, and a rubber plate 374 is fixedly connected to the bottom of the elastic rope 373. The top of the rubber plate 374 is in movable contact with the bottom of the conical cover 372. Waste liquid discharged from the discharge valve 293 enters the inner cavity of the collection chamber 35 through the receiving cylinder 37. After the waste liquid enters the interior of the receiving cylinder 37, it presses down on the rubber plate 374 by its own gravity. The rubber plate 374 stretches the elastic rope 373, causing a gap to be created between the top of the rubber plate 374 and the bottom of the conical cover 372, which facilitates the entry of waste liquid. After the waste liquid enters, the elastic rope 373 will drive the rubber plate 374 to reset, sealing the inner cavity of the receiving cylinder 37. Compared with traditional open containers, this reduces the amount of waste liquid evaporation.

[0029] The working principle of this ship's fuel tank with automatic drainage function will be explained in detail below.

[0030] like Figures 1-6 As shown, during use, the cavity formed by the oil storage tank 22 and the closed bottom plate 21 can store marine fuel. Fuel can be added from the refueling port 25 and taken from the oil outlet 27. The water content sensor 291 monitors the water content of the fuel inside the monitoring box 29. When the water content exceeds the threshold, the controller 292 will automatically control the drain valve 293 to open. When the water content is below the threshold, the controller 292 will control the drain valve 293 to close, realizing the automatic drainage function and ensuring the effectiveness of marine fuel use.

[0031] It should be noted that, in the description of this disclosure, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joint" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.

[0032] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
