[0034] The following, in conjunction with the accompanying drawings, describes in detail the specific structure of a ship fuel discharge device 10 provided in an embodiment of the present application. To more clearly illustrate the structure of the discharge device, the following embodiment uses a double-walled pipe as an example for describing the ship fuel storage device. It should be understood that a double-walled pipe is a special pipe structure consisting of two inner and outer pipe layers. This double-walled pipe can store various types of ship fuel (e.g., methanol fuel, hydrogen fuel, etc.). In other embodiments, the ship fuel storage device can also use other existing structures besides double-walled pipes.
[0035] like Figure 1 As shown, an embodiment of the present application provides a ship fuel discharge device 10 , including a first valve 101 , a second valve 102 , and a tank 103 .
[0036] The first valve 101 includes a liquid inlet and a liquid outlet, wherein the liquid inlet of the first valve 101 is connected to the discharge port of the outer tube of the double-walled tube 20. In some embodiments, the first valve 101 can be any type of valve. As one implementation, the first valve 101 can be an automatic valve, including but not limited to an electric valve, a pneumatic valve, a solenoid valve, or a hydraulic valve. As another implementation, the first valve 101 can also be a manual valve, including but not limited to a manual gate valve, a manual ball valve, or a manual butterfly valve.
[0037] In some embodiments, the first valve 101 and the discharge port of the double-walled pipe 20 can be connected by a discharge pipe 104, so that the connection between the two can have better sealing. The discharge pipe 104 can be a hard pipe or a soft pipe, and this embodiment does not specifically limit it.
[0038] The second valve 102 includes a liquid inlet and a liquid outlet, wherein the liquid inlet of the second valve 102 is connected to the liquid outlet of the first valve 101 via a connector 105. Similar to the first valve 101, the second valve 102 may also be any type of valve. For example, the second valve 102 may be an automatic valve, including but not limited to an electric valve, a pneumatic valve, a solenoid valve, or a hydraulic valve. In another example, the second valve 102 may also be a manual valve, including but not limited to a manual gate valve, a manual ball valve, or a manual butterfly valve.
[0039] The housing 103 includes a liquid inlet and a liquid outlet, wherein the liquid inlet of the housing 103 is connected to the liquid outlet of the second valve 102. As an implementation method, the liquid inlet can be located on a tubular structure protruding from the top surface of the housing 103, and the tubular structure can be integrally formed with the housing 103. The tubular structure can have various shapes, such as cylindrical or prismatic. The tubular structure facilitates the connection between the second valve 102 and the housing 103. The liquid outlet of the housing 103 is used to discharge the collected leaked fuel. Therefore, the liquid outlet of the housing 103 can be set on the bottom surface of the housing 103; the liquid outlet of the housing 103 can also be set on the side of the housing 103 and close to the bottom surface of the housing 103.
[0040] In some embodiments, a third valve 106 may be connected to the liquid outlet of the box 103 to control the discharge of liquid in the box 103 through the third valve 106. The type of the third valve 106 can refer to the introduction of the first valve 101 and the second valve 102 above, and will not be repeated here.
[0041] It should be noted that, for the convenience of control, the first valve 101 , the second valve 102 and the third valve 106 can be valves of the same type.
[0042] In some embodiments, a lifting member 107 may be provided on the top surface of the container 103 for lifting the container 103 to transfer the container 103 to the exterior of the vessel for drainage. In this embodiment, the lifting member 107 may be a lifting eye plate. In other embodiments, the lifting member 107 may be a lifting lug, a lifting ring, a lifting hook, or other forms.
[0043] The connector 105 is used to connect the second valve 102 located on the side of the housing 103 and the first valve 101 located on the side of the double-walled pipe 20. To allow leaked fuel to flow smoothly into the housing 103 through the connector 105, the connector 105 in this embodiment is provided with through holes that are compatible with the first valve 101 and the second valve 102. For example, the connector 105 can be a glasses flange, or a blind flange.
[0044] In some embodiments, the ship fuel discharge device 10 may further include a discharge controller 108, which is connected to the first valve 101 and is used to control the opening and closing of the first valve 101. The discharge controller 108 is also connected to the second valve 102 and is used to control the opening and closing of the second valve 102. Each ship fuel discharge device 10 may correspond to a discharge controller. It should be understood that the connection between the discharge controller 108 and the first valve 101 and the second valve 102 can be wired, such as via a cable, or wireless or communication connection, such as via Wi-Fi or Bluetooth.
[0045] In some embodiments, the ship fuel discharge device 10 may further include a first liquid level detection sensor 109 and / or a second liquid level detection sensor 110 .
[0046] The first liquid level detection sensor 109 is located on the side of the tank 103 and must be close to the bottom of the tank 103, for example, at 5% of the tank capacity (i.e., within 5% of the bottom). Specifically, the first liquid level detection sensor 109 serves as a low liquid level detection device for detecting and obtaining first liquid level information. The first liquid level detection sensor 109 is also connected to the discharge controller 108 to transmit the first liquid level information to the discharge controller 108.
[0047] The second liquid level detection sensor 110 is located on the side of the tank 103 and must be close to the top surface of the tank 103, for example, at 90% of the tank capacity (i.e., within 10% of the top). This second liquid level detection sensor 110 serves as a high liquid level detection device for detecting and obtaining second liquid level information. The second liquid level detection sensor 110 is also connected to the discharge controller 108 to transmit the second liquid level information to the discharge controller 108.
[0048] In this embodiment, the first liquid level detection sensor 109 and the second liquid level detection sensor 110 are float switches. In other embodiments, the first liquid level detection sensor 109 and the second liquid level detection sensor 110 may also be other types of liquid level detection devices, such as capacitance, resistance, pressure, ultrasonic, etc.
[0049] In some embodiments, the side where the liquid level detection sensor (the first liquid level detection sensor 109 and the second liquid level detection sensor 110 ) is provided and the side where the liquid outlet is provided may be different sides of the box.
[0050] In some embodiments, the connection between the discharge controller 108 and the first liquid level detection sensor 109 and the second liquid level detection sensor 110 can be a wired connection (for example, via a cable connection) or a wireless or communication connection (for example, via Bluetooth or WIFI connection).
[0051] In some embodiments, the ship fuel discharge device 10 may further include a centralized controller 111 , which is connected to the discharge controller 108 via a wired or wireless manner.
[0052] In some embodiments, the ship fuel discharge device 10 may further include an alarm 112 , which is connected to the centralized controller 111 via a wired or wireless manner.
[0053] Next, the working principle of the ship fuel discharge device 10 is introduced.
[0054] In this ship fuel discharge device 10, the first valve 101, connector 105, and second valve 102 are all initially open, while the third valve 106 is initially closed. When a fuel leak occurs in the double-walled pipe 20, the leaked fuel automatically flows into the tank 103 via the discharge pipe 104, the first valve 101, the connector 105, and the second valve 102. When the liquid level in the tank 103 reaches a first height, triggering the first liquid level sensor 109 to operate, the first liquid level detected by the first liquid level sensor 109 is transmitted to the discharge controller 108. The discharge controller 108 then transmits the first liquid level signal to the centralized controller 111. The centralized controller 111 controls the alarm 112 to issue a first alarm, thereby generating a first alarm. This first alarm indicates that the ship fuel discharge device 10 is operating normally. When the liquid level in the box 103 reaches the second height and the second liquid level detection sensor 110 starts to work, the second liquid level signal detected by the second liquid level detection sensor 110 is transmitted to the discharge controller 108, and the discharge controller 108 then transmits the second liquid level signal to the centralized controller 111. The centralized controller 111 controls the alarm 112 to issue a second alarm message to perform a second alarm, wherein the second alarm is used to indicate a high liquid level alarm so that the staff can drain the box.
[0055] Among them, the drainage process can be carried out according to the following steps:
[0056] A. Close the first valve 101 and the second valve 102, and turn the connector 105 to the blind plate side. This step can be controlled automatically or manually.
[0057] B. Remove the connection between the second valve 102 and the liquid inlet of the box 103;
[0058] C. If the first liquid level detection sensor 109, the second liquid level detection sensor 110, and the discharge controller 108 are connected by cables, remove the cables; if they are connected wirelessly, proceed to the next step;
[0059] D. The tank 103 is hoisted outside the cabin by the hoisting device through the hoisting member 107 , and the third valve 106 is controlled to open at the target position to drain the liquid fuel in the tank 103 .
[0060] In some embodiments, the ship fuel discharge device 10 may also include a fuel leakage detection device 30, which is connected to the centralized controller 111 by wired or wireless means, and is used to control the alarm 112 to issue a third alarm when a fuel leakage is detected. The third alarm is used to indicate the occurrence of a fuel leakage phenomenon.
[0061] In some embodiments, the initial state of the first valve 101, the connecting piece 105, and the second valve 102 can also be a closed state. After the fuel leakage detection device 30 detects a fuel leakage, a control instruction is sent to the discharge controller 108 through the centralized controller 111, and the first valve 101, the connecting piece 105, and the second valve 102 are controlled to open through the discharge controller 108.
[0062] The ship fuel discharge device provided by the above embodiment can not only promptly discharge the leaked fuel from the double-walled pipe after a fuel leak occurs, but also collect the discharged fuel, thereby ensuring the safety of fuel use. It can also realize the linkage between leaked fuel detection and collection, thereby providing a reminder to the on-duty personnel.
[0063] Another embodiment of the present application provides a ship, which includes a hull, a fuel leakage detection device, and the discharge device provided in the above embodiment.
[0064] The fuel leakage detection device and the discharge device are both arranged on the hull, and the fuel leakage detection device and the discharge device are connected to each other and are used to activate the discharge device when a fuel leakage is detected to remind the duty personnel or collect the leaked fuel.

Those skilled in the art will understand that the present application is not limited to the specific embodiments herein, and that various obvious changes, readjustments, and substitutions can be made by those skilled in the art without departing from the scope of protection of the present application.
