Detailed Description

The present invention is further described with reference to the following drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.

Referring to fig. 1, a schematic view of an embodiment of the wear-resistant protective sleeve for a flexible pipe cable according to the present invention is shown. The utility model discloses a protective sheath includes protective sheath body 10 and hoop staple bolt 20, and protective sheath body 10 coils on the umbilical, and hoop staple bolt 20 holds protective sheath body 10 tightly outside the umbilical. For guaranteeing that protective sheath body 10 can adapt to not unidimensional umbilical, protective sheath body 10 is the barrel of being formed by the body spiral winding of area, protective sheath body 10 winding is on the umbilical, consequently, protective sheath body 10 can be elongated or radially enlarge or reduce along the axial for it can be hugged closely in the cable or the hose outside of inside parcel, realizes reliable contact laminating, simultaneously because protective sheath body 10 itself is the form of coiling promptly, so protective sheath body 10 winding can not take place loose situation behind the umbilical outside. Preferably, in this embodiment, the inner diameter of the cylinder is smaller than the width of the belt body, so as to ensure the winding effect of the protective sheath body 10 on the umbilical cable and reduce the probability of loosing the protective sheath body 10. In order to further ensure the tightness of the protection sleeve body 10 and the pipe cable, the hoop 20 is clamped outside the protection sleeve body 10. On one hand, the protective sleeve body 10 and the pipe cable wrapped inside are tightly fixed into a whole, so that the dislocation cannot occur, and on the other hand, the protective sleeve is prevented from being loose. For the installation hoop staple bolt 20, a plurality of annular 11 are provided with outward to protective sheath body 10, hoop staple bolt 20 card is established in annular 11. Therefore, even the pipe cable produces tensile hoop staple bolt 20 of crooked can not the displacement yet, the fixed effect to protective sheath body 10 is influenced, and simultaneously, hoop staple bolt 20 can not bulge to protective sheath body 10 outsidely, prevents that wearing and tearing from causing premature failure.

Referring to fig. 2, in order to meet the requirement of the abrasion-resistant protection length or area of the submarine cable or hose, the protective sheath body 10 is provided in plurality. Up to the length of the total package to be protected. In order to ensure that the pipe cable between adjacent protective sleeves can be protected, the adjacent protective sleeve bodies 10 are clamped with each other, specifically, one end of each protective sleeve body 10 is provided with a circle of inner grooves 12, and the other end of each protective sleeve body 10 is provided with a circle of outer convex rings 13 corresponding to the inner grooves 12. The inner groove 12 is clamped with the outer convex ring 13 to realize axial connection and fixation. The inner groove 12 at the end of the first protective sleeve body 10 is clamped to the outer convex ring 13 at the end of the second adjacent protective sleeve body 10, so that continuous extension of a single protective sleeve is realized, and supplement adjustment can be performed at any time according to actual needs. The protective sleeve has no disconnection in the circumferential direction, has no local hard collision, can better provide wear-resistant protection, and is stable and reliable in long-term use.

In order to realize the rapid molding of the protective sheath body 10, the protective sheath body 10 is molded by casting polyurethane. The polyurethane material is soft, does not influence the bending of tube cable, and all wearing and tearing that cause with the seabed contact of tube cable when the seabed removes all are born by protective sheath body 10, and polyurethane's wearability is good, can guarantee the safety of long-term use.

Further, the hoop 20 is made of corrosion-resistant steel belts. Can ensure long-term use in complex environment. In order to ensure that the hoop 20 hoops the protective casing body 10, the ends of the hoop 20 are locked by bolts. Meanwhile, in order to ensure that the hoop 20 is tightly connected with the protective sleeve body 10, an anti-slip layer is arranged on the inner surface of the hoop 20.

The utility model discloses at the during operation, spiral protective sheath body 10 has been made according to the design of the external diameter scope of tube and cable, and the length of specific quantity installation as required is considered certain surplus to go on, and hoop staple bolt 20 is made according to the requirement and is accomplished and be equipped with relevant erection equipment, and all are shipped to the installation scene. The position that needs the wear-resisting protective sheath of installation is with protective sheath body 10 spiral expansion back winding cover in the outside of tube and cable, with the inner groovy 12 end of protective sheath body 10 outwards to install in protective sheath body 10 outside annular 11 and hold tightly fixedly hoop 20, accomplish the installation of a single section fixedly. Then another protective sheath body 10 is spirally unfolded and then wound and sleeved outside the pipe cable, the end of the inner groove 12 of the protective sheath body is clamped with the end of the outer convex ring 13 of the fixed protective sheath body 10 to form the fastening type for fixing, so that the axial connection is realized, and then the annular hoop 20 is installed, so that the protective sheath body 10 at the section is hooped outside the pipe cable. Similar operations in the same way are performed to fix the subsequent protective sleeve body 10 until the overall length meets the required protection length requirement, and the installation is completed. And then laying the pipe cable and putting the pipe cable on the seabed. If local damage of one appears after a period of time, can be through dragging for local umbilical cord, then several sets of wear-resisting protective sheath with the damage remove, install new protective sheath body 10 again, make its spiral expand after the winding cover in the outside of umbilical cord, realize local change.

The above-mentioned embodiments are merely preferred embodiments for fully illustrating the present invention, and the scope of the present invention is not limited thereto. Equivalent substitutes or changes made by the technical personnel in the technical field on the basis of the utility model are all within the protection scope of the utility model. The protection scope of the present invention is subject to the claims.
