[0002] In the current shipbuilding industry, with the widespread use of new green fuels such as methanol or liquid ammonia, more and more operating ships choose these low-flashpoint fuels as their power source.

A detection tube 3 is arranged on one side of the transport main pipe 2, and the detection tube 3 is a "U"-shaped structure, and the two ends of the detection tube 3 are respectively fixedly connected to the side walls of the transport main pipe 2 and are relatively connected. A detection component 4 is arranged on the detection tube 3, and the detection component 4 can detect the situation inside the detection tube 3. A plurality of control valves are arranged on the detection tube 3 and the transport main pipe 2, and the control valves are connected to the detection component 4 in a relative signal manner. A temperature adjustment component 5 is also arranged on the supporting base plate 1, and the temperature adjustment component 5 is relatively connected to the inside of the transport main pipe 2, and the temperature inside the transport main pipe 2 is adjusted by the temperature adjustment component 5.

[0028] The transport main pipe 2 includes an inner transport pipe 21 located inside, and an outer transport pipe 22 is sleeved on the outer side of the inner transport pipe 21. The inner transport pipe 21 and the outer transport pipe 22 are coaxially arranged, and a distance is left between the outer wall of the inner transport pipe 21 and the inner wall of the outer transport pipe 22 to form a transport annular cavity 23.

[0029] The detection tube 3 includes an inner detection tube 31 located inside, and an outer detection tube 32 is sleeved on the outer side of the detection inner tube 31. The detection inner tube 31 and the detection outer tube 32 are coaxially arranged, and a distance is left between the outer wall of the detection inner tube 31 and the inner wall of the detection inner tube 31 to form a detection ring cavity 33.

[0030] The detection tube 3 is connected to the inlet end of the transport main tube 2, and the other end of the detection tube 3 is connected to the tail end of the transport main tube 2, and the detection inner tube 31 is fixedly connected and relatively connected to the transport inner tube 21, the detection outer tube 32 is fixedly connected and relatively connected to the transport outer tube 22, and the detection annular cavity 33 is relatively connected to the transport annular cavity 23.

[0031] The transport main pipe 2 is provided with a first control valve 6 between the two ends of the detection pipe 3, and the first control valve 6 is used to control the on-off of the inside of the transport inner pipe 21. When the first control valve 6 is closed, the medium at the inlet end of the transport main pipe 2 enters the inside of the detection inner pipe 31, and is detected by the detection component 4 located on the detection inner pipe 31.

After receiving the data information of the data processing module 43, the driving module 44 can open or close the second control valve 7 and the third control valve 8 according to the information requirements.

[0035] Reference Figure 2 , Figure 3 The liquid inlet end of the transport main pipe 2 is provided with a sealing assembly 9, which includes a first sealing semi-ring 91 and a second sealing semi-ring 92 located inside the transport ring cavity 23. The first sealing semi-ring 91 and the second sealing semi-ring 92 are both semi-circular ring structures, and the first sealing semi-ring 91 and the second sealing semi-ring 92 can form a complete ring structure after being relatively abutted. The abutting surfaces of the first sealing semi-ring 91 and the second sealing semi-ring 92 are vertically arranged. The first sealing semi-ring 91 includes a semi-circular hard structure located inside and a soft structure wrapped around the outside of the hard structure. The second sealing semi-ring 92 includes a semi-circular hard structure located inside and a soft structure wrapped around the outside of the hard structure. In some embodiments, the soft structure can be made of rubber sealing material.

[0036] The inner wall of the first sealing half ring 91 abuts against the outer wall of the transport inner tube 21, and the outer wall of the first sealing half ring 91 abuts against the inner wall of the transport outer tube 22. The inner wall of the second sealing half ring 92 abuts against the outer wall of the transport inner tube 21, and the outer wall of the second sealing half ring 92 abuts against the inner wall of the transport outer tube 22.

[0037] A driving assembly 93 is arranged above the first sealing half ring 91 and the second sealing half ring 92. The driving assembly 93 can drive the first sealing half ring 91 and the second sealing half ring 92 to rotate. The first sealing half ring 91 and the second sealing half ring 92 rotate in opposite directions, so that the first sealing half ring 91 and the second sealing half ring 92 are deformed under the action of the transport inner tube 21 and the transport outer tube 22, and then a gap is formed inside the transport ring cavity 23, so that the liquid inlet end is connected.

[0041] When the ship fuel is in the process of transportation, the first control valve 6 is first closed to allow the fuel to pass through the detection inner tube 31 on the other side. At the same time, the pressure of the fuel inside the detection inner tube 31 is monitored by the pressure sensor 41, and the data is transmitted to the data processing module 43 for detection. At the same time, whether there is fuel in the detection annular cavity 33 between the detection inner tube 31 and the detection outer tube 32 is monitored by the fuel sensor 42, and the data is transmitted to the data processing module 43 for detection.

[0042] When it is detected that the pressure inside the detection inner tube 31 changes greatly and there is leaked fuel in the detection ring cavity 33 between the detection inner tube 31 and the detection outer tube 32, the second control valve 7 and the third control valve 8 are controlled to be closed through the driving module 44, and the rotating motor 932 is controlled to drive the driving gear 933 to rotate, thereby driving the first sealing half ring 91 and the second sealing half ring 92 to close, so that the fuel delivery can be stopped and the detection ring cavity 33 between the detection inner tube 31 and the detection outer tube 32 can be sealed to avoid excessive fuel leakage.

[0043] Reference Figure 2 , Figure 4 The temperature adjustment component 5 includes a temperature detector 51, which is fixedly connected to the side wall of the transport main pipe 2, and the detection end of the temperature detector 51 is located inside the transport inner pipe 21.
