The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0025] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides an underwater umbilical cable terminal device. The underwater umbilical cable terminal device includes a terminal body 10, which has a chamber 11 and an access port connected to the chamber 11, and the terminal body 10 is provided with a hydraulic docking component 101, an electric socket 102 and an optical socket 103; a transmission part, including a hydraulic distribution pipeline 104, an optical fiber line 105 and a power line 109, and the hydraulic distribution pipeline 104, the optical fiber line 105 and the power line 109 enter the chamber 11 through the access port; wherein the hydraulic distribution pipeline 104 is connected to the hydraulic docking component 101, the power line 109 is connected to the electric socket 102, the optical fiber line 105 is connected to the optical socket 103, the hydraulic docking component 101 is configured to be able to quickly connect and release with the liquid flying line, the electric socket 102 is configured to be able to quickly connect and release with the electric flying line, and the optical socket 103 is configured to be able to quickly connect and release with the optical flying line.

[0026] In the above technical solution, the terminal body 10 can divert the light, electricity and liquid transported in the umbilical cable underwater through the optical fiber line 105, the power line 109 and the hydraulic distribution pipeline 104 in the chamber 11, and then quickly connect with the underwater oil and gas production equipment through the optical socket 103, the electric socket 102 and the hydraulic docking component 101 respectively. In this way, by setting up a quick connection structure (optical socket 103, optical fiber line 105, power line 109), the installation time can be shortened, and the above operations can be completed using an underwater robot, thereby realizing the rapid docking of the umbilical cable with the underwater oil and gas production equipment, and solving the problem that the underwater umbilical cable terminal device and the underwater oil and gas production equipment are difficult to quickly and safely connect in the prior art.

[0027] Furthermore, on the one hand, in the terminal body 10, any two of the hydraulic distribution pipelines 104, the optical fiber lines 105 and the power lines 109 are arranged at intervals, so that the arrangements of the hydraulic distribution pipelines 104, the optical fiber lines 105 and the power lines 109 in the terminal body 10 do not interfere with each other, that is, there will be no overlap between any two of the hydraulic distribution pipelines 104, the optical fiber lines 105 and the power lines 109, and the transmission of media such as light, electricity, and liquid can be distinguished to achieve rapid docking of the umbilical cable with underwater oil and gas production equipment, so as to avoid the problem of inconvenience in connecting with underwater oil and gas production equipment due to the excessive and scattered number of optical fiber lines 105, power lines 109 and hydraulic distribution pipelines 104 of the umbilical cable, and also solve the problem of complex overall connection structure and arrangement of underwater oil and gas production equipment in the prior art. In this way, the connection operation process is relatively simple, and installation and maintenance save time.

[0028] Specifically, in an embodiment of the present invention, the terminal body 10 is made of metal material, and the overall load capacity of the terminal body 10 is higher than that of the optical fiber line 105, the hydraulic distribution pipeline 104, and the power line 109. In this way, the optical fiber line 105, the hydraulic distribution pipeline 104, and the power line 109 are installed inside the terminal body 10, and the terminal body 10 can play a good protective role for the optical fiber line 105, the hydraulic distribution pipeline 104, and the power line 109, thereby improving safety.

[0029] Specifically, in an embodiment of the present invention, the hydraulic docking component 101 can adopt a hydraulic quick-connect connector, which can be quickly connected to and released from the liquid flying line; the electric socket 102 can adopt an underwater pluggable electric connector socket, which can be quickly connected to and released from the electric flying line, and the optical socket 103 can adopt an underwater pluggable optical connector socket, which can be quickly connected to and released from the optical flying line. The specific structures of the hydraulic quick-connect connector, the socket of the underwater pluggable electric connector and the socket of the underwater pluggable optical connector can adopt the existing technology, as long as the function of rapid disassembly and assembly can be achieved, and no further details will be given here.

[0030] Specifically, in the embodiment of the present invention, there are six electrical sockets 102 and six optical sockets 103 , and the electrical sockets 102 or the optical sockets 103 are fixed to the terminal body 10 by means of bolt locking.

[0031] It should be noted that in the embodiment of the present invention, the routing arrangement of the optical fiber line 105 inside the terminal body 10 can be changed according to the allocation requirements of different optical units, and the routing arrangement of the power line 109 inside the terminal body 10 can be changed according to the allocation requirements of different electrical units.

[0032] It should be noted that in the embodiment of the present invention, the number and type of electrical sockets 102 can be selected to facilitate access to multiple cables. Similarly, the number and type of optical sockets 103 can be selected to facilitate access to multiple optical cables, thereby achieving control of more functions.

[0033] like Figure 2 As shown, the terminal body 10 includes a cover plate, a sealing plate 114, two side ear plates 110 and a back plate, wherein the two side ear plates are spaced apart and located between the cover plate and the sealing plate 114, and the back plate is located between the two side ear plates 110 and between the cover plate and the sealing plate 114, wherein the electrical socket 102 is located on one of the two side ear plates 110, and the optical socket 103 is located on the other of the two side ear plates 110, and the relative positions of the multiple electrical sockets 102 on the corresponding side ear plates 110 can be arranged as needed, and the relative positions of the multiple optical sockets 103 on the corresponding side ear plates 110 can be arranged as needed.

[0034] It should be noted that, in the embodiment of the present invention, the hydraulic fly line is used to connect the underwater distribution system and the underwater oil and gas production equipment, and plays the role of transmitting hydraulic power.

[0035] It should be noted that, in the embodiments of the present invention, the optical fly line is a fiber optic communication cable used in underwater production systems. The optical fly line utilizes fiber optic technology to transmit status information and sensor data of underwater equipment in real time, thereby meeting the data transmission requirements of underwater equipment.

[0036] It should be noted that in the embodiments of the present invention, the electric flying wire is a cable used for underwater or seabed operations, used to connect an offshore platform with underwater equipment to transmit power and electrical signals, wherein the signals include control signals, sensor signals, and data communications.

[0037] like Figure 2 As shown, in the embodiment of the present invention, the underwater umbilical cable terminal device further includes a protective cap 106 detachably connected to the hydraulic docking component 101 , and the protective cap 106 is covered on the hydraulic docking component 101 .

[0038] In the above technical solution, when the underwater oil and gas production equipment is not started, the protective cap 106 can play a protective role to prevent marine organisms from attaching to the hydraulic docking component 101; when the underwater oil and gas production equipment needs to be started, the protective cap 106 can be removed and the hydraulic flying line can be quickly installed on the hydraulic docking component 101 to start the underwater oil and gas production operation.

[0039] It should be noted that, in the embodiment of the present invention, the position and number of the protective caps 106 can be changed as required. Similarly, the electrical socket 102 and the optical socket 103 can also be provided with protective caps 106 .

[0040] like Figure 2 and Figure 3 As shown, in an embodiment of the present invention, a sealing plate 114 is provided at the access port, a wiring channel 111 and a pipe channel 112 located around the wiring channel 111 are provided on the sealing plate 114, the hydraulic distribution pipeline 104 enters the chamber 11 through the pipe channel 112, and the optical fiber line 105 and the power line 109 enter the chamber 11 through the wiring channel 111.

[0041] In the above technical solution, the optical fiber line 105 and the power line 109 enter the terminal body 10 through the wiring channel 111 of the sealing plate 114, and are respectively connected to the optical socket 103 and the electrical socket 102. The hydraulic distribution pipeline 104 enters the terminal body 10 through the pipeline channel 112. In this way, the directions of the optical unit, electrical unit, and liquid unit of the umbilical cable can be distributed to achieve the purpose of distinguishing the transmission medium, so that it can be quickly connected with the underwater oil and gas production equipment, avoiding the problem of complicated construction.

[0042] It should be noted that, in the embodiment of the present invention, the sealing plate 114 is welded to the terminal body 10 .

[0043] Specifically, in the embodiment of the present invention, the number of pipeline channels 112 is set to 7.

[0044] It should be noted that, in the embodiment of the present invention, the wiring channel 111 is configured as a central hole, wherein the outer diameter of the cable formed by the optical fiber line 105 and the power line 109 is A, and the inner diameter of the central hole is greater than 1.2A.

[0045] Preferably, in the embodiment of the present invention, the inner diameter of the central hole is greater than or equal to 1.2 A and less than or equal to 3 A. Thus, the diameter of the central hole can be enlarged or reduced within the above value range to pass optical fiber lines 105 and power lines 109 of different sizes.

[0046] like Figure 2 As shown, in the embodiment of the present invention, the hydraulic distribution pipeline 104 is a steel pipe, and the steel pipe is bent multiple times in the chamber 11, and each bending angle of the steel pipe is less than 90°.

[0047] Through the above-mentioned arrangement, on the one hand, the bending arrangement of the steel pipe can change the flow direction of the liquid, so that the liquid in the hydraulic distribution pipeline 104 flows into the underwater oil and gas production equipment through the hydraulic docking component 101; on the other hand, the bending angle of the steel pipe in the chamber 11 does not exceed 90°, thus preventing the steel pipe from failing due to excessive wall thickness thinning due to excessive curvature.

[0048] Furthermore, by enabling the hydraulic distribution line 104 to be bent multiple times, the routing arrangement of the hydraulic distribution line 104 inside the terminal body 10 can be changed according to the distribution requirements of different liquid media, that is, the hydraulic distribution line 104 can be bent twice, three times or four times according to the distribution requirements of different liquid media.

[0049] In one embodiment, the hydraulic distribution pipeline 104 may also include a plurality of straight pipes made of steel and at least one right-angle joint made of steel, wherein the right-angle joint is used to connect two adjacent straight pipes among the plurality of straight pipes to realize a curved setting of the hydraulic distribution pipeline 104 .

[0050] It should be noted that, in the embodiments of the present invention, the number of steel pipes can be increased or decreased according to demand.

[0051] It should be noted that, in the embodiment of the present invention, the steel pipe can be bent multiple times in the terminal body 10, so that the steel pipe has multiple bending angles in the terminal body 10, wherein the multiple bending angles of the steel pipe in the terminal body 10 do not exceed 90°.

[0052] like Figure 2 As shown, in an embodiment of the present invention, the power line 109 is bent in the chamber 11, and the bending radius of the power line 109 is larger than its own minimum bending radius; and / or, the optical fiber line 105 is bent in the chamber 11, and the bending radius of the optical fiber line 105 is larger than its own minimum bending radius.

[0053] Through the above arrangement, damage and failure of the power line 109 and the optical fiber line 105 can be avoided.

[0054] It should be noted that, in the embodiments of the present invention, the minimum bending radius refers to the minimum bending radius of the material without being damaged or significantly reducing its service life during operation, and is the minimum value of the bending radius that can be achieved without damaging the material.

[0055] It should be noted that, in an embodiment of the present invention, if the power line 109 has multiple bends, the bending radius of the power line 109 being greater than its own minimum bending radius means that multiple bending radii are greater than its own minimum bending radius; similarly, the bending radius of the optical fiber line 105 being greater than its own minimum bending radius means that multiple bending radii are greater than its own minimum bending radius.

[0056] like Figure 2 As shown, in the embodiment of the present invention, the underwater umbilical cable terminal device further includes an anti-corrosion component 107 located in the chamber 11, and the anti-corrosion component 107 is made of sacrificial anode material.

[0058] Specifically, in the embodiment of the present invention, the anti-corrosion component 107 is an anode block.

[0059] It should be noted that in the embodiments of the present invention, the sacrificial anode material is a metal material used for cathodic protection, which protects pipelines or other metal structures from corrosion by electrochemical methods. This material has a sufficiently negative potential and can be used as an anode in an electrochemical cell, and is gradually consumed as the current flows out, thereby protecting the metal structure connected thereto (i.e., the cathode) from corrosion. For example, the sacrificial anode material can be a magnesium material.

[0069] Specifically, in the embodiment of the present invention, glue may be poured into the internal through hole of the fixing member 30 to fix the hydraulic distribution pipeline 104 .

For the convenience of description, the two protective caps 106 are respectively referred to as the first protective cap and the second protective cap.

[0071] Through the above-mentioned arrangement, when the underwater oil and gas production equipment is not started, the two protective caps 106 can play a protective role to prevent marine organisms from attaching to the two hydraulic docking components 101. When the underwater oil and gas production equipment needs to be started, the first protective cap can be removed and the hydraulic flying line can be quickly installed on the hydraulic docking component 101, and the second protective cap can protect the corresponding hydraulic docking component 101 to start the underwater oil and gas production operation; when it is necessary to switch, produce, maintain and overhaul the hydraulic circuit of the underwater oil and gas production equipment, the first protective cap can be kept on the corresponding hydraulic docking component 101, the second protective cap can be taken out, and the liquid flying line can be connected to coordinate the transportation logic of the hydraulic pipeline.
