Embodiment 1

[0025] see Figure 1 to Figure 3 , the present invention provides a cable protection device, comprising a triangular protective sheath 1, said protective sheath 1 comprising a first protective leaf 2, a second protective leaf 3 and a third protective leaf 4, said first protective leaf 2 is connected to the left side of the second protection leaf 3 through a door hinge 5, the third protection leaf 4 is connected to the right side of the second protection leaf 3 through a door hinge 5, and the first protection leaf 2 and The outer side of the third protection page 4 is provided with a first lock assembly 6 that can cooperate with each other, and the first protection page 2 and the third protection page 4 are snapped together by the first lock assembly 6, and the protection sleeve The upper end and the lower end of the shell 1 are provided with a second lock assembly 7 that can cooperate with each other, and the adjacent protective cover shells 1 are snapped together by the secon...

Embodiment 2

[0030] see Figure 4 and Figure 5 The difference between this embodiment and Embodiment 1 is that the first locking assembly 6 includes a first card seat 611 and a first card member 612, and the first card seat 611 is installed on the first protection sheet 2 , the first clip 612 is installed on the third protection sheet 4, and the first clip 612 is clamped with the first clip 611 and then fixedly connected by bolts to strengthen the first protection sheet 2 and the second protection sheet. While protecting the stability of the connection of the page 4, it is convenient for subsequent disassembly and replacement.

[0031] The second locking assembly 7 includes a second card seat 711 and a second card member 712, and the second card seat 711 is located at the lower end of the first protection leaf 2, the second protection leaf 3 and the third protection leaf 4 , the second clip 712 is located on the upper ends of the first protection sheet 2, the second protection sheet 3 a...

Embodiment 3

[0033] see Figure 6 The difference between this embodiment and Embodiments 1 and 2 is that the arc splint 9 and the cable support 8 are detachably clamped, and this device is equipped with arc splints 9 with different arc radii, which can be adjusted according to the seabed. The diameter of the cable is selected and replaced to improve the adaptability and the fixing effect on the submarine cable.

[0034] The middle part of the first protection sheet 2, the second protection sheet 3 and the third protection sheet 4 is hollowed out, except for the frame of the protection sheet and the cable support 8, the rest of the parts are hollowed out, and the protective cover 1 is protected by waves. When impacting, the waves can pass through the protective casing 1 , which greatly weakens the impact of the waves on the protective casing 1 and improves the stability of the protective casing 1 .

[0035] The middle part of described first protection leaf 2, the second protection leaf 3 ...

Abstract

The present invention relates to a cable protection device, which comprises a triangular protective sheath. The protective sheath comprises a first protective leaf, a second protective leaf and a third protective leaf. The first protective leaf is connected to the left side of the second protective leaf through a door hinge. side, the third protection page is connected to the right side of the second protection page through a door hinge, the outside of the first protection page and the third protection page are provided with a first lock assembly that can cooperate with each other, the first protection page and the third protection page The pages are snapped together by the first lock assembly, and the upper and lower ends of the protective cover are provided with a second lock assembly that can cooperate with each other. The adjacent protective sleeves are snapped by the second lock assembly. The first protective page, the second The center of the second protection page and the third protection page are respectively equipped with a cable support, and the cable support is connected with a concave arc-shaped splint. This device has a simple structure and light weight. Strong replaceability, simple installation, convenient and flexible assembly.

Description

technical field [0001] The invention relates to the field of cable protection, in particular to a cable protection device. Background technique [0002] Submarine power cables play an increasingly important role in offshore power energy transmission, and have been widely used in island power supply, independent grid connection, offshore wind farm power output, offshore oil platform power supply, and power transmission across rivers and straits. The damage factors of submarine power cables mainly include the external force damage to the cable by ship anchors and fishing gear, the corrosion of the cable armor by the marine environment, the fatigue damage to the lead sheath of the cable caused by vortex vibration, the tensile damage to the cable caused by construction and salvage, and the damage caused by sea waves. Abrasion of cables impairs operation, insulation aging and joint failure, etc. Once the submarine cable is damaged, it is necessary to use various means to find th...
