Technical Field

[0001] This application relates to the technical field of umbilical cable terminals, and in particular to an integrated vibration-damping terminal for multiple pipelines of umbilical cables on offshore platforms. Background Technology

[0002] An umbilical cable is a multi-functional deep-sea composite cable that integrates power transmission, signal control, and communication transmission. It is mainly used to connect surface facilities and underwater equipment, and it docks with the underwater equipment through the umbilical cable terminal.

[0003] A search revealed Chinese Patent Publication No. CN114744583B, which discloses an umbilical cable terminal. The key technical features are: integrating the hydraulic lines, electrical cables, and optical cables of the umbilical cable into a set of docking panels; achieving docking and locking with underwater production equipment in a single operation via a hydraulic locking device, resulting in high docking efficiency; and equipping it with optical flywires to solve the problem of long-distance, high-signal-volume control transmission; simultaneously, it is equipped with multiple pairs of optical and electrical flywires for docking with underwater equipment, making it more flexible and convenient, and ensuring more timely signal feedback and transmission, reducing the risk of damage to underwater equipment or even oilfield shutdowns due to untimely signal feedback.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: Since the umbilical cable terminal needs to connect the umbilical cable and underwater equipment underwater, it often needs to withstand continuous vibration loads caused by ocean currents, ship movement, and mechanical operations, resulting in metal fatigue and wear of the sealing structure, which reduces the service life of the umbilical cable terminal.

[0020] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0021] This application discloses an integrated vibration damping terminal for multiple pipelines of umbilical cables on offshore platforms. For example... Figure 1 , Figure 2 as well as Figure 3 As shown, the device includes a terminal integrated housing 1 and an integrated connector 2. An umbilical cable body 3 is slidably connected to the inner wall of the terminal integrated housing 1. A first arc-shaped clamping plate 10 is fitted on the surface of the umbilical cable body 3, and a second arc-shaped clamping plate 11 is fitted on the surface of the umbilical cable body 3. A pad 12 is fixedly connected to the side of the first arc-shaped clamping plate 10 and the second arc-shaped clamping plate 11 that are close to each other. The pad 12 is made of fluororubber. The side of the pad 12 that is close to the umbilical cable body 3 is in close contact with the umbilical cable body 3. During the process of using the first arc-shaped clamping plate 10 and the second arc-shaped clamping plate 11 to clamp the umbilical cable body 3, the pad 12 can minimize the damage to the umbilical cable body 3 caused by shaking.

[0022] Please see Figure 3 and Figure 4 A connecting plate 13 is fixedly connected to the surface of the first arc-shaped clamping plate 10, and a mounting plate 14 is fixedly connected to the side of the connecting plate 13. Two fixing plates 4 are fixedly connected to the side of the terminal integrated housing 1 near the first arc-shaped clamping plate 10. Movable plates 9 are fixedly connected to the sides of both the first arc-shaped clamping plate 10 and the second arc-shaped clamping plate 11 near the fixing plates 4. The mounting plate 14 and the first arc-shaped clamping plate 10 can be connected through the connecting plate 13, and the first arc-shaped clamping plate 10 can be connected to the terminal integrated housing 1 through the fixing plates 4. The inner wall of the mounting plate 14 is fixedly connected with a stranded wire 15, and both ends of the stranded wire 15 are fixedly connected with anti-vibration hammers 16. The two fixed plates 4 are provided with sliding grooves on the side near the moving plate 9. The surfaces of the sliding grooves on the two fixed plates 4 are slidably connected with sliding strips 5. The vertical cross section of the sliding strips 5 is trapezoidal. The anti-vibration hammers 16 can play a shock-absorbing role. The sliding strips 5 and the moving plate 9 enable the first arc-shaped clamping plate 10 and the second arc-shaped clamping plate 11 to be connected to the fixed plate 4 while ensuring that the two can move relative to the fixed plate 4.

[0023] Please see Figure 4The movable plate 9 is slidably connected to the fixed plate 4 on the side away from the terminal integrated housing 1. The end of the slide bar 5 near the umbilical cable body 3 is fixedly connected to the drive plate 7. The side of the drive plate 7 near the fixed plate 4 is rotatably connected to the adjusting screw 8. The adjusting screw 8 is threaded into the inner wall of the fixed plate 4. When it is necessary to adjust the position of the movable plate 9, the adjusting screw 8 can be rotated to drive the drive plate 7 to move closer to or away from the fixed plate 4, thereby controlling the position adjustment of the drive plate 7.

[0024] Please see Figure 4 The side of the slider 5 away from the terminal integrated housing 1 is fixedly connected to the moving plate 9. The end of the slider 5 away from the umbilical cable body 3 is fixedly connected to the limiting plate 6. The vertical cross section of the limiting plate 6 is rectangular. The slider 5 and the moving plate 9 are fixedly connected so that the movement of the slider 5 can drive the moving plate 9 to move synchronously. At the same time, it can ensure the stable installation of the moving plate 9. The limiting plate 6 can ensure the stability of the installation of the slider 5 as much as possible.

[0025] The implementation principle of the multi-pipeline integrated vibration damping terminal for umbilical cables on an offshore platform according to this application embodiment is as follows: After the umbilical cable body 3 is connected to the underwater equipment through the terminal integrated housing 1 and the integrated connector 2, the adjusting screw 8 is rotated to make it rotate on the inner wall of the fixed plate 4 and the surface of the driving plate 7. Under the restriction of the sliding strip 5, the driving plate 7 drives the sliding strip 5 to slide on the surface of the sliding groove on the fixed plate 4, thereby moving the limiting plate 6 closer to the fixed plate 4. The movement of the driving plate 7 controls the moving plate 9 to move closer to the umbilical cable body 3, thereby the first arc-shaped clamping plate The first arc-shaped clamp 10 and the second arc-shaped clamp 11 clamp the umbilical cable body 3. At this time, the anti-vibration hammer 16 is connected to the umbilical cable body 3 through the stranded wire 15, the mounting plate 14 and the connecting plate 13. When the umbilical cable body 3 vibrates, its vibration is transmitted to the anti-vibration hammer 16, causing the anti-vibration hammer 16 to shake, thereby consuming the vibration energy and achieving the vibration reduction effect of the umbilical cable body 3. When the umbilical cable body 3 shakes, the pad plate 12 can minimize the damage to the umbilical cable body 3 caused by the first arc-shaped clamp 10 and the second arc-shaped clamp 11. The first arc-shaped clamp 10, the second arc-shaped clamp 11 and the mounting plate 14 can easily connect the anti-vibration hammer 16 to the umbilical cable body 3, so that the anti-vibration hammer 16 can absorb the vibration of the umbilical cable body 3, minimizing the damage to the umbilical cable body 3 caused by the impact of ocean currents, ship movement and mechanical operations, and improving the service life of the umbilical cable body 3.

[0026] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
