The rotating plate assembly is arranged inside the main pipe 1, the timing assembly is connected to the outer side wall of the main pipe 1, and the rotating plate assembly is connected to the timing assembly; the biting mechanism includes a spiral assembly and a biting assembly. The spiral assembly is arranged on the lower end side wall of the main pipe 1, the biting assembly is arranged on the lower end side wall of the main pipe 1, and the spiral assembly is located above the biting assembly.

[0025] Insert the second transition pipe 3 into the port of the oil storage container, and turn the spiral assembly to drive the biting assembly to bite the port of the oil storage container so that the main pipe 1 is connected to the oil storage container without shaking. Connect the first transition pipe 2 at the upper end of the main pipe 1 to the oil unloading pipe and use the fastening mechanism to tightly connect the first transition pipe 2 and the oil unloading pipe; during the oil unloading process, the oil impels the rotating plate assembly through the main pipe 1. The rotation of the rotating plate assembly causes the timing assembly to start recording the oil injection time. Then, by reading the oil injection time on the timing assembly, and then dividing the capacity of the container by the time when the container is full, the oil unloading rate of the oil unloading vessel can be obtained. This method uses a machine to replace manual time recording. One person can record the full time of multiple containers at the same time, with high efficiency and accurate oil injection time.

[0026] Specifically, the fastening mechanism includes two first shaft connecting seats 19, which are connected to the upper end of the side wall of the main pipe 1. A connecting rod 20 is movably connected between the two first shaft connecting seats 19. The upper end of the connecting rod 20 is movably connected to one end of a first semi-circular fastening ring 21 and a second semi-circular fastening ring 22. An opening 23 is formed at one end of the first semi-circular fastening ring 21 away from the connecting rod 20.

A plurality of through holes 26 are equidistantly formed at one end of the second semi-circular fastening ring 22 away from the connecting rod 20.

[0027] Insert the first transition pipe 2 into the oil discharge pipe, then butt the first semi-circular fastening ring 21 and the second semi-circular fastening ring 22, insert the second semi-circular fastening ring 22 into the opening 23 of the first semi-circular fastening ring 21, and then use the bolt 25 to pass through the threaded insertion hole 24 and the through hole 26, so that the inner walls of the first semi-circular fastening ring 21 and the second semi-circular fastening ring 22 are pressed against the oil discharge pipe sleeved on the first transition pipe 2.

[0028] Specifically, the spiral assembly includes a spiral rotating ring 28, and an internal thread 27 is formed at the lower end of the side wall of the main pipe 1. The spiral rotating ring 28 is connected to the internal thread 27. The biting assembly includes two second shaft connecting seats 29, which are connected to the lower end of the side wall of the main pipe 1. A biting member 30 is movably connected between the two second shaft connecting seats 29. There are four groups of biting assemblies, which are respectively equidistantly arranged on the lower side wall of the main pipe 1.

[0029] Insert the second transition pipe 3 into the port of the oil storage container, turn the spiral rotating ring 28, and the spiral rotating ring 28 moves downward to squeeze the upper end of the biting member 30, so that the lower end of the biting member 30 bites the port of the oil storage container, making the connection between the main pipe 1 and the oil storage container not shake.

[0030] Specifically, the turning plate assembly includes a rotating plate 4. A rotating shaft 5 is connected to each side of the rotating plate 4. The two rotating shafts 5 are respectively movably connected to the inner wall of the main pipe 1. The outer end of one rotating shaft 5 passes through the main pipe 1 and is connected to a timing component. The timing component includes two moving plates 6. The two moving plates 6 are connected to the side wall of the rotating shaft 5. An iron block 8 is connected to the back surface of each of the two moving plates 6. A contact block 7 is connected to the back surface of each of the two moving plates 6. A fixing block 9 is connected to the side wall of the main pipe 1 on both sides of the rotating shaft 5. An electromagnet 11 is connected to the opposite surface of each of the two fixing blocks 9. A contact sensor 10 is connected to the upper end surface of the fixing block 9 on the right side of the rotating shaft 5. A contact sensor 10 is connected to the lower end surface of the fixing block 9 on the left side of the rotating shaft 5. The timing component is located inside the protection box 15. A single-chip microcomputer 16 and a timer 17 are respectively connected to the outer side wall of the protection box 15. The two contact sensors 10 are electrically connected to the single-chip microcomputer 16. The single-chip microcomputer 16 is electrically connected to the timer 17. A fixing ring 18 is connected to the side wall of the main pipe 1. The fixing ring 18 is located outside the rotating shaft 5. Two first baffles 12 are connected to the inner side of the fixing ring 18. Two second baffles 14 are connected to the side wall of the rotating shaft 5 located inside the fixing ring 18. A spring 13 is connected to the side of the second baffle 14 close to the first baffle 12.

[0031] When injecting oil into the oil storage container, the oil will rush towards the right side of the rotating plate 4 under the action of the diversion plate 31 through the main pipe 1, causing the rotating plate 4 to reverse to the right, and further causing the rotating shaft 5 to rotate clockwise. The rotating shaft 5 drives the two moving plates 6 to rotate, so that the two moving plates 6 contact the fixing blocks 9 on both sides. While the rotating shaft 5 rotates, the electromagnet 11 is energized to generate magnetic force. When the moving plate 6 contacts the fixing block 9, the magnetic force generated by the electromagnet 11 will attract the iron block 8 on the moving plate 6, so that the moving plate 6 and the fixing block 9 are always in contact. At the same time, because the contact sensor 10 contacts the contact block 7, the contact sensor 10 sends a signal to the single-chip microcomputer 16, and the single-chip microcomputer 16 sends the signal to the timer 17. The timer 17 starts to work and count time. After the oil injection is completed, the electromagnet 11 is powered off and loses magnetic force. The rotating plate 4 flips back to the previous flat state due to gravity. At this time, because the contact block 7 leaves the contact sensor 10, the single-chip microcomputer 16 sends a signal to the timer 17, and the timer 17 stops counting time. Read the time on the timer 17, and then divide the capacity of the container by the time when the container is full to obtain the oil unloading rate of the oil unloading ship.

[0032] Working principle: Insert the first transition pipe 2 into the oil discharge pipe, then butt the first semi-circular fastening ring 21 and the second semi-circular fastening ring 22, insert the second semi-circular fastening ring 22 into the opening 23 of the first semi-circular fastening ring 21, and then use bolts 25 to pass through the threaded insertion holes 24 and through holes 26, so that the inner walls of the first semi-circular fastening ring 21 and the second semi-circular fastening ring 22 tightly press the oil discharge pipe sleeved on the first transition pipe 2. Insert the second transition pipe 3 into the port of the storage container, turn the spiral rotating ring 28, and the spiral rotating ring 28 moves downward to squeeze the upper end of the engaging member 30, so that the lower end of the engaging member 30 engages with the port of the storage container to make the main pipe 1 connected to the storage container without shaking. When injecting oil into the storage container, the oil will rush to the right side of the rotating plate 4 under the action of the diversion plate 31 through the main pipe 1, causing the rotating plate 4 to reverse to the right, and further causing the rotating shaft 5 to rotate clockwise. The rotating shaft 5 drives the two moving plates 6 to rotate, so that the two moving plates 6 contact the fixed blocks 9 on both sides. While the rotating shaft 5 rotates, the electromagnet 11 is energized to generate a magnetic force. When the moving plate 6 contacts the fixed block 9, the magnetic force generated by the electromagnet 11 will attract the iron block 8 on the moving plate 6, so that the moving plate 6 and the fixed block 9 always contact each other. At the same time, because the contact sensor 10 contacts the contact block 7, the contact sensor 10 sends a signal to the single-chip microcomputer 16, and the single-chip microcomputer 16 sends the signal to the timer 17. The timer 17 starts to work and time. After the oil injection is completed, the electromagnet 11 is powered off and loses its magnetic force, and the rotating plate 4 flips back to its previous flat state due to gravity. At this time, because the contact block 7 leaves the contact sensor 10, the single-chip microcomputer 16 sends a signal to the timer 17, and the timer 17 stops timing. Read the time on the timer 17, and then divide the capacity of the container by the time when the container is full to obtain the oil discharge rate of the oil barge.
