Abstract
Description
Technical Field
[0001] This invention relates to the field of cable protection technology, specifically to a cable conduit support mechanism for marine engineering. Background Technology
[0002] In marine engineering, especially in the fields of offshore wind power, offshore oil and gas platforms and cross-sea bridges, cable conduits are key components that protect submarine cables or optical cables from seawater corrosion, mechanical damage, interference from fishing activities and wave erosion. These conduits usually need to be fixed to platform jackets, pile foundations or other underwater structures by various support mechanisms. However, existing clamping mechanisms lack flexible, retractable structures at the clamping points, posing a risk of long-term relaxation and stress concentration. Most existing cable conduit clamping mechanisms are rigid contacts, which, during long-term operation, are prone to weakening due to corrosion from the marine environment, material aging, and the micro-movements and vibrations of the conduit itself caused by waves and currents. Furthermore, when there is an angular deviation between the actual route of the conduit and the preset installation surface of the support structure, construction personnel can only adapt by bending or cutting the conduit, which limits the design flexibility and on-site adjustability of the conduit's support angle. Summary of the Invention

The inner sides of the two rubber rings continuously approach each other and continuously embed into the first semi-circular shell and the second semi-circular shell, so that the protective tube forms a flexible bonding interface when it is clamped by the clamping component, thereby effectively preventing fatigue damage, wear and fall-off of the protective tube.

The metal ring in the fixing component can be sleeved on the outer circumference of the structural rod. The circumferential locking is achieved by tightening the upper and lower rings and the thread of the through nut. The connecting block and the ring can be finely adjusted according to the installation position so that the whole mechanism can fit securely on different installation surfaces. The inner rod performs telescopic and rotational movements in the outer cylinder to adapt to the protective tubes of different diameters or installation angles.

Detailed Implementation
[0015] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the invention and to fully convey the scope of the invention to those skilled in the art.
[0016] This invention provides a support mechanism for cable conduits in marine engineering. It includes a tightening assembly. Rotating the handle causes a ratchet to drive a first bevel gear, which in turn meshes with and drives second bevel gears on both sides to rotate in opposite directions. Because the second bevel gears have internal threads, the external screws connected to them achieve synchronous axial tightening under the gear rotation, thereby pulling the herringbone rods towards the center. This causes the two sets of pull rods to drive rubber rings to radially compress and cover the outer surface of the conduit. The inner sides of the two rubber rings continuously approach and embed into the first and second semi-circular shells, forming a flexible, fitted interface when the conduit is clamped by the clamping assembly. This effectively prevents fatigue damage, wear, and detachment of the conduit. The exposed mounting includes a fixing component and a telescopic rotation component. The fixing component securely connects the structural rod to the base. The metal ring in the fixing component can be fitted onto the outer circumference of the structural rod, and circumferential locking is achieved by tightening the upper and lower rings and the threaded through-nut. The connecting block and the ring can be finely adjusted in angle according to the installation position, so that the entire mechanism can fit securely on different installation surfaces. The inner rod telescopically and rotates within the outer cylinder to adapt to protective tubes of different diameters or installation angles. When adjusted to the appropriate position, the outer cylinder is locked by the hoop and the first connecting piece, thereby fixing the telescopic length and rotation angle of the inner rod and ensuring that the clamping assembly is in the required clamping position, thus increasing the flexibility and on-site adjustability of the clamping mechanism.
[0017] like Figure 1As shown, the cable conduit support mechanism for marine engineering provided by the present invention includes: a structural rod 1; a telescopic rotating assembly 3 and a fixing assembly 2, wherein the telescopic rotating assembly 3 is fixed to the top curved surface of the structural rod 1 by the fixing assembly 2, and the telescopic rotating assembly 3 is used to adjust the installation position and installation angle of the cable conduit; a clamp assembly 4, disposed on the top of the telescopic rotating assembly 3, for clamping the cable conduit; and a tightening assembly 5, for tightening the clamp assembly 4 so that the clamp assembly 4 clamps the cable conduit.

[0019] It should be noted that the inner rod 38 extends, retracts, and rotates within the outer cylinder 34 to accommodate cable conduits of different diameters or installation angles. Once adjusted to the appropriate position, the outer cylinder 34 is locked in place by the clamp 36 and the first connecting piece 37, thereby fixing the extension length and rotation angle of the inner rod 38 and ensuring that the clamping assembly 4 is in the required clamping position.

[0020] In the above embodiments, preferably, as follows: Figure 2 and Figure 3 As shown, the fixing component 2 includes: a metal ring 21, a loop ring 22, a through nut 23, a connecting block 24, and a circular ring 25; the metal ring 21 is sleeved on the outside of the structural rod 1 and is tightly fitted to the structural rod 1; the first ends of the two loop rings 22 are respectively hinged to the two ends of the metal ring 21; the first end of the connecting block 24 is hinged to the second end of the loop ring 22, and its second end is hinged to the circular ring 25; the circular ring 25 passes through the first circular hole 33 on each trapezoidal block 32 in sequence; wherein, the loop ring 22 is a two-half loop ring structure including an upper ring and a lower ring, and the upper ring and the lower ring are connected by the through nut 23.
[0021] It should be noted that the fixing component 2 can securely connect the structural rod 1 to the base. The metal ring 21 in the fixing component 2 can be sleeved on the outer circumference of the structural rod 1, and circumferential locking is achieved by tightening the threads of the upper and lower rings 22 and the through nut 23. The connecting block 24 and the ring 25 can be finely adjusted according to the installation position so that the entire mechanism can be stably fitted on different installation surfaces. After fitting, the base 31 is then welded to the structural rod 1.

[0023] In the above embodiments, preferably, the second connecting member 44 is a connecting bolt or pin assembly. Figure 5 The bolts are not connected, but of course, they can be... Figure 5 The connecting bolts in the middle are replaced with pin assemblies.
[0024] In the above embodiments, preferably, as follows: Figure 6 As shown, the pin assembly includes: a top shell 44-1, a tension spring 44-2, a bottom shaft 44-3, and a pin 44-4; the top shell 44-1 is inserted into the mating surface of the first semi-circular shell 41 and the mating surface of the second semi-circular shell 42; the tension spring 44-2 is disposed inside the top shell 44-1, one end of which is connected to the inner top of the top shell 44-1, and the other end of which is connected to the bottom shaft 44-3; the pin 44-4 is inserted into the bottom shaft 44-3 to abut against the insertion hole of the mating surface.
[0025] In the above embodiments, preferably, as follows: Figure 5As shown in Figures 7 to 9, the tightening assembly 5 includes: a rubber ring 51, a pull rod 52, a housing 53, a ratchet 55, a handle 57, a first bevel gear 58, a second bevel gear 59, an external screw 510, and a herringbone rod 511; two rubber rings 51 are symmetrically arranged at both ends of the first semi-circular shell 41 and the second semi-circular shell 42 forming an integral whole; a second circular hole 54 is provided in the center of the housing 53; the ratchet 55 is disposed in the second circular hole 54, and the handle 57 is fixedly connected to the ratchet 55; the bottom of the ratchet 55 is fixedly connected to the first bevel gear 58; two second bevel gears 59 are respectively disposed on both sides of the first bevel gear 58, and the two second bevel gears 59 respectively mesh with the first bevel gear 58; an external screw 510 is threaded into each of the two second bevel gears 59; one end of each of the two external screws 510 is connected to the first end of the herringbone rod 511; the two second ends of each herringbone rod 511 are fixedly connected to the first ends of the two pull rods 52; the second ends of the two pull rods are respectively connected to the corresponding rubber rings 51.
[0026] In the above embodiment, preferably, the tightening component 5 further includes a lever 56; one end of the lever 56 is hinged to the top of the housing 53, and the other end engages with the edge of the ratchet 55; a torsion spring is installed at the hinge point between the lever 56 and the top of the housing 53 to prevent the ratchet 55 from reversing.
[0027] It should be noted that the working process of the tightening assembly is as follows: The cable conduit is placed into the clamp assembly. The rubber ring 51 has a slit design to facilitate the fitting of the cable conduit. The handle 57 is rotated, and the ratchet 55 drives the first bevel gear 58 to rotate. The first bevel gear 58 then simultaneously meshes and drives the second bevel gears 59 on the left and right sides to rotate in opposite directions. Since the second bevel gear 59 has an internal thread, the external screw 510 connected to it achieves synchronous axial tightening movement under the rotation of the gear, thereby pulling the herringbone rod 511 closer to the center. This causes the two sets of pull rods 52 to drive the rubber ring 51 to compress radially and cover the outer surface of the conduit. The inner sides of the two rubber rings 51 continuously approach each other and continuously embed into the first semi-circular shell 41 and the second semi-circular shell 42. When the rubber ring 51 is tightened by the pull rod 52, it generates a circumferential preload, forming a flexible contact interface. This not only effectively disperses stress concentration on the surface of the protective tube, but also absorbs impact energy through the micro-elastic deformation of the rubber under the action of ocean currents and wave vibrations, thereby preventing rigid collisions and fatigue wear of the protective tube. At the same time, the torsion spring structure between the ratchet 55 and the lever 56 can prevent the ratchet 55 from reversing, ensuring that the locked state is maintained for a long time. When maintenance or disassembly is required, simply turn the handle 57 in reverse to release the ratchet 55 from locking, the outer screw 510 gradually retracts, the herringbone rod 511 loosens the pull rod 52, the rubber ring 51 returns to its original shape, and the clamp assembly 4 can elastically open, thus facilitating the replacement or position adjustment of the protective tube.
[0028] Furthermore, the working process of this invention is as follows: When using this equipment, firstly, the structural rod 1 is securely connected to the base of the telescopic rotating component through the fixing component 2. The metal ring 21 in the fixing component 2 can be sleeved on the outer circumference of the structural rod 1, and circumferential locking is achieved by tightening the threads of the upper and lower rings 22 and the through nut 23. The connecting block 24 and the ring 25 can be finely adjusted according to the installation position so that the entire mechanism can be securely fitted on different installation surfaces. After fitting, the base 31 is then welded to the structural rod 1. Next, the inner rod 38 extends and rotates within the outer cylinder 34 to accommodate cable conduits of different diameters or installation angles. Once adjusted to the appropriate position, the outer cylinder 34 is locked by the clamp 36 and the first connector 37, thereby fixing the extension length and rotation angle of the inner rod 38 and ensuring that the clamping assembly 4 is in the required clamping position. The connection between the inner rod 38 and the outer cylinder 34 can also be further reinforced by welding. The protective tube is placed into the clamp assembly 4. The rubber ring 51 has a slit design to facilitate the fitting of the protective tube. The first semi-circular shell 41 and the second semi-circular shell 42 are initially clamped by the elastic locking structure formed by the tension spring 44-2 in the pin assembly. The pin 44-4 ensures that the two semi-circular shells will not loosen due to vibration when locked, which facilitates the insertion of the protective tube. When the screw on the other side is locked, the first semi-circular shell 41 and the second semi-circular shell 42 can be combined into a whole. Then, rotating the handle 57 causes the ratchet 55 to drive the first bevel gear 58 to rotate. The first bevel gear 58 then simultaneously engages and drives the second bevel gears 59 on both sides to rotate in opposite directions. Since the second bevel gear 59 has an internal thread, the external screw 510 connected to it achieves synchronous axial tightening under the rotation of the gear, thereby pulling the herringbone rod 511 closer to the center. This causes the two sets of pull rods 52 to drive the rubber rings 51 to compress radially and cover the outer surface of the protective tube. The inner sides of the two rubber rings 51 continuously approach each other and continuously embed themselves into the first semi-circular shell 41 and the second semi-circular shell 42. When maintenance or disassembly is required, simply turn the handle 57 in reverse to release the ratchet 55 lock, the first external screw 510 gradually retracts, the herringbone rod 511 loosens the pull rod 52, the rubber ring 51 returns to its original shape, and the clamp assembly 4 can then elastically open, thus facilitating the replacement or position adjustment of the protective tube.
[0029] In addition, it should be noted that the inner diameter of the rubber ring 51 in the present invention is slightly smaller than the outer diameter of the cable conduit under normal conditions. The rubber ring is elastic, and the two rubber rings are fitted on the outer surface of the cable conduit and continuously come closer to each other, thereby forming a ring-shaped pre-tightening force.
[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
