Description

Technical Field

[0001] The invention belongs to the technical field of marine engineering, and in particular relates to a cable protective tube with adjustable direction. Background Art

[0002] In the design process of the cable protection tube, the direction of the cable protection tube on the seabed needs to be determined according to the cable route and the orientation of the landing platform so that the submarine cable can enter the cable protection tube smoothly. However, in the actual design process, it is often encountered that the cable protection tube is reserved for future oil field development. At this time, the route of the cable protection tube cannot be determined in advance because the future oil field development plan is unclear.

[0003] The traditional design is to only reserve the support base of the cable protection tube on the main structure, and install the cable protection tube at sea after the future cable landing plan is determined. The traditional design requires a lot of offshore operations, the use of floating cranes, and a large number of divers for underwater connections. In addition, it is necessary to complete the precise docking of the cable protection tube with the reserved base in a harsh marine environment, which sometimes even affects the platform production operation and causes temporary suspension of production. Obviously, the traditional design is difficult to construct at sea, has a high risk factor, and requires high construction costs.

[0004] Therefore, it is urgent to design a direction-adjustable cable protective tube to solve the above-mentioned problem of the cable protective tube reserved for future development. Summary of the invention

[0005] In order to solve the technical problems mentioned in the background technology, the traditional design scheme requires a large amount of offshore operation workload, requires the use of floating cranes, and a large number of divers to make underwater connections. In addition, it is necessary to complete the precise docking operation of the cable guard tube and the reserved base in a harsh marine environment. Sometimes it even affects the platform production operation and causes temporary suspension of production. A direction-adjustable cable guard tube is provided to solve the problem of reserved cable guard tubes for future development.

[0006] To achieve the above-mentioned purpose, the specific technical solution of the direction-adjustable cable protection tube of the present invention is as follows: A cable conduit with adjustable direction comprises a cable conduit fixing part and a cable conduit rotatable structural assembly, wherein the cable conduit rotatable structural assembly is arranged at one end of the cable conduit fixing part, the cable conduit fixing part is connected to a conduit frame leg through a cable conduit support, the cable conduit rotatable structural assembly maintains concentricity with the cable conduit fixing part, and the cable conduit rotatable structural assembly is fixed to the conduit frame leg.

[0007] Furthermore, the cable protection tube rotatable structure assembly comprises a cable protection tube rotatable part, and the cable protection tube rotatable part maintains concentricity with the cable protection tube fixed part.

[0008] Furthermore, the cable protection tube rotatable structure assembly also includes a cable protection tube rotation axis, which is welded to the rotatable part of the cable protection tube, and the cable protection tube rotation axis coincides with an extension line of the center line of the fixed part of the cable protection tube.

[0009] Furthermore, the cable protection tube rotating shaft is fixed to the rotating shaft base U-shaped clip fixing mechanism through a first U-shaped clip.

[0010] Furthermore, one side where the rotatable part of the cable protective tube is connected to the fixed part of the cable protective tube is fixedly connected to the horizontal support U-shaped clip fixing base through a second U-shaped clip, and the horizontal support U-shaped clip fixing base is connected to the catheter frame leg through the horizontal support beam of the rotating body.

[0011] Furthermore, the horizontal support U-shaped clip fixing base is welded to the horizontal support beam of the rotating body, and a reinforcing rib plate is connected between the horizontal support beam of the rotating body and the horizontal support U-shaped clip fixing base.

[0012] Furthermore, one end of the vertical rib plate connected above the horizontal support beam of the rotating body is welded to the horizontal support U-shaped clip fixing base, and the other end is welded to the cable protection pipe fixing part.

[0013] Furthermore, the rotating shaft base U-shaped clamp fixing mechanism is welded on the rotating shaft base.

[0014] Furthermore, the rotating shaft base is welded to the supporting channel steel, one end of the supporting channel steel away from the rotating shaft base is welded to the conductor frame leg, and an oblique supporting channel steel is welded between the supporting channel steel and the conductor frame leg.

[0015] Furthermore, the rotatable portion of the cable protection tube is connected to the main structure of the conductor frame through an anchor chain to limit the angle of the rotatable portion of the cable protection tube.

[0016] The direction-adjustable cable protection tube of the present invention has the following advantages: The U-shaped clip is used to connect the lateral support of the protective tube to the protective tube. When the direction needs to be adjusted, the U-shaped clip fastener only needs to be loosened, and then the cable protective tube is rotated around the rotation axis. After the adjustment, the U-shaped clip fastener is re-tightened, and the anchor chain is used to limit it to prevent it from rotating under the action of the current. This application does not require the use of resources for offshore installation in future applications, and can be pre-installed in advance during the land construction stage of the conductor frame. Since it has the function of adjusting the direction, the direction can be freely adjusted according to the route of the future cable, so that the construction is simple, fast, safe and efficient in future use.

[0023] The U-shaped clip is used to connect the lateral support of the protective tube to the protective tube.

After the adjustment is completed, the U-shaped clip fastener is re-tightened, and the anchor chain 17 is used to limit it to prevent it from rotating under the action of the current. This application does not require the use of resources for offshore installation in future applications, and can be pre-installed in advance during the land construction stage of the conductor frame. Since it has the function of adjusting the direction, the direction can be freely adjusted according to the route of the future cable, so that the construction is simple, fast, safe and efficient in future use.

[0024] Further, if Figure 1 and Figure 4 As shown, the cable protection tube rotatable structure assembly 3 includes a cable protection tube rotatable part 5, which maintains concentricity with the cable protection tube fixed part 2; the cable protection tube rotatable structure assembly 3 also includes a cable protection tube rotating shaft 6, which is welded to the cable protection tube rotatable part 5, and the cable protection tube rotating shaft 6 coincides with the extension line of the center line of the cable protection tube fixed part 2; the cable protection tube rotating shaft 6 is fixed to the rotating shaft base U-shaped clip fixing mechanism 10 by a first U-shaped clip 7.

[0025] In this embodiment, the cable guard fixed part 2 is welded to the conductor frame leg 1 by the cable guard support 4, the cable guard rotatable part 5 in the cable guard rotatable structure assembly 3 maintains concentricity with the cable guard fixed part 2, and is fixed to the conductor frame leg 1 through the rotating body horizontal support beam 9 and the oblique support channel steel 16.

[0026] The cable protection tube rotatable structure assembly 3 is mainly composed of a cable protection tube rotating shaft 6, a first U-shaped clip 7, a second U-shaped clip 8, a cable protection tube rotatable part 5, a rotating body horizontal support and a rotating shaft base 14, and a supporting channel steel 15.

[0027] Further, if Figure 2 and Figure 5 As shown, one side of the cable protective tube rotatable part 5 connected to the cable protective tube fixed part 2 is fixedly connected to the horizontal support U-shaped clip fixing base 13 through the second U-shaped clip 8, and the horizontal support U-shaped clip fixing base 13 is connected to the catheter frame leg 1 through the rotating body horizontal support beam 9; the horizontal support U-shaped clip fixing base 13 is welded to the rotating body horizontal support beam 9, and a reinforcing rib plate 12 is connected between the rotating body horizontal support beam 9 and the horizontal support U-shaped clip fixing base 13; one end of the vertical rib plate 11 connected above the rotating body horizontal support beam 9 is welded to the horizontal support U-shaped clip fixing base 13, and the other end is welded to the cable protective tube fixed part 2.

[0028] In this embodiment, the first U-shaped clip 7 fixes the rotatable part 5 of the cable protective tube on the horizontal support U-shaped clip fixed base 13, and the fixed base is welded to the horizontal support beam 9 of the rotating body.

A part of the vertical rib plate 11 above the beam is welded to the horizontal support U-shaped clip fixed base 13, and a part is welded to the fixed part 2 of the cable protective tube to play a dual role of reinforcement and limiting.

[0029] The cable conduit has applicability and does not have a fixed orientation. It can be simply adjusted to adapt to different routing orientations of future submarine cables landing on offshore oil platforms. It can be fully installed on the conductor rack during the land prefabrication installation stage, and does not require large-scale offshore lifting group peer installation work. Preferably, the cable conduit can arbitrarily adjust the orientation of the seabed section of the conduit.

When the direction needs to be adjusted, it is only necessary to loosen the U-shaped clip fasteners, and then rotate the cable protection tube around the rotating shaft. After the adjustment is completed, the U-shaped clip fasteners are re-tightened.

[0033] The direction-adjustable cable conduit is connected to the conduit through a U-shaped clip via a lateral support of the conduit. When the direction needs to be adjusted, the U-shaped clip fastener only needs to be loosened, and then the cable conduit is rotated around the rotation axis. After the adjustment is completed, the U-shaped clip fastener is re-tightened, and the anchor chain 17 is used to limit it to prevent it from rotating under the action of the current. This application does not require the use of resources for offshore installation in future applications, and can be pre-installed in advance during the land construction stage of the conductor frame. Since it has the function of adjusting the direction, the direction can be freely adjusted according to the future cable route, so that the construction is simple, fast, safe and efficient in future use.
