[0045] In order to achieve a quick connection between the receiving ship and the bunkering ship, the present embodiment provides a quick cable fixing device and method, which can quickly connect the receiving ship and the bunkering ship, can save costs and meet the needs of emergency release of mooring cables.

[0046] Figure 1 A schematic diagram of a first state of a fast cable fixing device provided by an embodiment of the present invention; Figure 2 A schematic diagram of a second state of a fast cable fixing device provided by an embodiment of the present invention; Figure 3 A schematic diagram of a first state of a fast cable fixing device provided by an embodiment of the present invention having two connecting members; Figure 4 A schematic diagram of a second state of the fast cable fixing device provided by an embodiment of the present invention having two connecting members; Figure 5 A schematic structural diagram of an automatic limit structure provided in an embodiment of the present invention.

[0047] like Figures 1 to 5 As shown, the quick cable fixing device includes a first connecting body 1, a connecting member 2, a cable fixing hook 3, a pin limit assembly 4 and a self-closing structure 5, wherein the connecting member 2 is used to connect the first connecting body 1 to the receiving vessel 100; the first end of the cable fixing hook 3 is pivotally connected to the first connecting body 1, and the second end of the cable fixing hook 3 can be inserted into the slot 11 of the first connecting body 1 and locked or released by the pin 6; the pin limit assembly 4 includes an automatic limit structure and an emergency handle 43, the automatic limit structure is used to automatically fix or automatically release the pin 6, and the emergency handle 43 is fixedly connected to the pin 6 for manually releasing or manually fixing the pin 6; the self-closing structure 5 is respectively connected to the first connecting body 1 and the cable fixing hook 3, and the self-closing structure 5 is used to drive the cable fixing hook 3 to have a tendency to always move toward the direction of the pin limit assembly 4.

[0048] The quick cable fixing device provided in the present embodiment can realize automatic fixing of the pin shaft 6 or automatic release of the pin shaft 6, manual fixing or manual release of the pin shaft 6 through the pin shaft limiting assembly 4, so that the pin shaft 6 can release or position the cable fixing hook 3. Such a setting can ensure that when the cable fixing hook 3 cannot be actively released or actively fixed by the automatic limiting structure, manual fixing or manual release can be achieved through the emergency handle 43 connected to the pin shaft 6. The structure of the quick cable fixing device provided in the present embodiment is relatively simple, which can save costs and meet the needs of emergency release of the mooring cable 15.

[0049] For example, the first connecting body 1 is made of lightweight and high-strength material, which is convenient for human portability and transportation.

[0050] In some embodiments, Figure 5 As shown, the automatic limit structure includes an elastic member 41 and an electromagnetic suction member 42. The elastic member 41 is sleeved on the pin 6. The electromagnetic suction member 42 can automatically absorb or release the pin 6. For example, the electromagnetic suction member 42 includes an electromagnet. After the coil of the electromagnet is energized, the iron core of the electromagnet absorbs the pin 6 so that the pin 6 can always maintain the posture of locking the cable fixing hook 3. After the coil of the electromagnet is de-energized, the magnetic force of the iron core of the electromagnet disappears. Under the action of the elastic member 41, the pin 6 can be separated from the slot 11 of the first connecting body 1.

[0051] In some embodiments, in combination Figures 1 to 4 , the number of the cable fixing hook 3 can be one, and the cable fixing hook 3 is an arc structure, and its arc center angle is less than 100°. In other embodiments, in order to avoid the cable fixing hook 3 being broken and requiring the overall replacement of the quick cable fixing device, the number of the cable fixing hook 3 is two, and correspondingly, the first connecting body 1 is provided with two slots 11, and the two slots 11 are arranged one-to-one with the two cable fixing hooks 3. Of the two cable fixing hooks 3, one is a spare part and the other is a common part. Of course, the two cable fixing hooks 3 can also be used alternately. For example, the cable fixing hook 3 is an arc-shaped round tube made of high-strength steel.

[0052] In order to clearly know the pulling force of the bunkering vessel 200 on the cable hook 3, a force monitoring component 7 is also provided at the second end of the cable hook 3 inserted into the slot 11, and the force monitoring component 7 is used to monitor the pulling force of the bunkering vessel 200 on the cable hook 3. For example, the force monitoring component 7 can be a pressure sensor, and specifically, the force monitoring component 7 can be a strain gauge, and the force monitoring component 7 converts the force on the cable hook 3 into current information, and displays it through a display connected to the force monitoring component 7, so that the operator can intuitively obtain the pulling force on the cable hook 3.

[0053] In some embodiments, the self-closing structure 5 includes a tensioning elastic member, one end of which is connected to the first connecting body 1, and the other end is connected to the cable fixing hook 3 so as to pull the cable fixing hook 3 to rotate relative to the first connecting body 1. The tensioning elastic member can make the cable fixing hook 3 always have a tendency to pull the cable fixing hook 3 to rotate in the direction of the slot 11, thereby ensuring that the cable fixing hook 3 can be pulled back to the slot 11 position by the tensioning elastic member after the cable is sleeved to wait for the pin 6 to be locked and fixed.

[0054] For example, the tensioning elastic member is a spring or an elastic rubber band, so that the tensioning elastic member can always have a tendency to pull the cable fixing hook 3 to rotate in the direction of the slot 11.

[0055] like Figure 3 , Figure 4 and Figure 8 As shown, there are two connectors 2, one of the ferrules of the two connectors 2 is connected to the first connecting body 1, and the other ferrules of the two connectors 2 are respectively connected to the two bollard heads with bollards 13 of the receiving ship 100. Reducing the number of connectors 2 can reduce the force on each connector 2 and improve the safety factor.

[0056] In some embodiments, Figure 7 and Figure 8 As shown, the connector 2 is a high-strength lightweight cable, and both ends of the connector 2 are provided with ferrules, one of the ferrules of the connector 2 is connected to the first connecting body 1, and the other ferrule of the connector 2 is connected to the mooring pile 13 of the receiving ship 100. In this way, the ferrules at both ends of the connector 2 can connect the receiving ship 100 with the fast cable fixing device, and since the ferrules are easy to quickly disassemble and assemble, the purpose of quickly connecting the receiving ship 100 and the fast cable fixing device can be achieved.

[0057] In some embodiments, in combination Figure 1 and Figure 6 As shown, the fast cable fixing device also includes a signal receiver 8, a wireless controller 9 and an audible and visual alarm 10. The wireless controller 9 is communicatively connected with the signal receiver 8, the automatic limit structure and the audible and visual alarm 10. The wireless controller 9 has a display screen 91 and buttons 92. The number of buttons 92 can be set according to actual needs. The audible and visual alarm 10 is integrated with the wireless controller 9, so that the tension detected by the force monitoring component 7 can be more intuitively fed back to the operator, so that the operator can quickly make an operation. In some embodiments, the signal receiver 8 is arranged on the first connecting body 1, and the signal receiver 8 is electrically connected to the force monitoring component 7 through an electric wire. The signal receiver 8 is used to communicate with the wireless controller 9 to realize signal transmission.

[0058] like Fig. 9 As shown, the ferrule of the connector 2 is sleeved on the mooring bollard 13 of the receiving vessel 100. Figure 6 As shown, one end of the mooring cable 15 is fixedly connected to the fairlead hole 14 of the filling vessel 200, specifically connected by a tether, and the other end of the mooring cable 15 passes through the fairlead hole 14 of the receiving vessel 100 and is connected by a fast cable fixing device. In order to prevent the receiving vessel 100 and the filling vessel 200 from collision and damage, a fender 16 is also provided between the receiving vessel 100 and the filling vessel 200 during the filling process.

[0059] This embodiment also provides a cable fixing method, which is applied to the fast cable fixing device provided in this embodiment, such as Fig.10 As shown, the following steps are included:

[0061] S2, making the pin shaft limiting assembly 4 release the pin shaft 6 to separate the cable fixing hook 3 from the first connecting body 1;

[0062] S3, putting the mooring cable 15 of the bunkering vessel 200 into the cable hook 3;

[0063] S4, the cable fixing hook 3 is rotated to enter the slot 11 of the first connecting body 1, and the pin limit assembly 4 locks the pin 6 to insert the cable fixing hook 3;

[0064] S5. After the filling operation is completed, reverse the operation to complete the mooring operation.

[0065] The method also includes: obtaining the tension detected by the force monitoring component 7 in real time and wirelessly transmitting it to the wireless controller 9 through the signal receiver 8, the wireless controller 9 compares the current tension with the preset tension, and if the current tension is greater than the preset tension, the sound and light alarm component 10 emits an alarm sound and emits a light warning.

[0066] The cable fixing method provided in the present embodiment is applied to the quick cable fixing device provided in the present embodiment, and the pin shaft 6 is automatically fixed or automatically released through the pin shaft limiting assembly 4, and the pin shaft 6 is manually fixed or manually released, so that the pin shaft 6 can release or position the cable fixing hook 3. Such a setting can ensure that when the cable fixing hook 3 cannot be actively released or actively fixed by the automatic limiting structure, manual fixing or manual release can be achieved through the emergency handle 43 connected to the pin shaft 6. The structure of the quick cable fixing device provided in the present embodiment is relatively simple, which can save costs and meet the needs of emergency release of the mooring cable 15.

[0067] The cable fixing device provided in this embodiment enables the dual-fuel ship to meet the requirement of rapid detachment of the mooring cable 15 in an emergency situation during ship-to-ship mooring; the cable fixing device can also be used for ship dock mooring, and the cost of the device is greatly reduced.
