Description

Technical Field

[0001] This utility model relates to the field of cable technology, and in particular to a high-strength lightweight cable. Background Technology

[0002] A cable is an electrical product used to transmit and distribute electrical energy. It consists of at least two conductors (usually copper or aluminum) along with insulation, a sheath, and other auxiliary materials. Cables enable the efficient and safe transmission of electrical energy from a power source to where it is needed.

[0003] Currently, cables used in aquatic environments typically employ a traditional circular structure, which has a small contact area with water and insufficient buoyancy, making them prone to breakage due to excessive weight during long-distance laying. At the same time, the metal reinforcement layer used to improve strength significantly increases the weight of the cable, which not only reduces buoyancy stability but also makes installation and maintenance more difficult, and makes it prone to fatigue damage under dynamic loads such as wave impact.

[0004] Therefore, we propose a high-strength, lightweight cable. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-strength, lightweight cable.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a high-strength lightweight cable, comprising a cable body, wherein a foamed sleeve is fixedly sleeved on the outer surface of the cable body;

[0007] Several float mechanisms are fixedly sleeved on the outer surface of the foam sleeve. The foam sleeve and the cable body form a curved section with a margin between adjacent float mechanisms. Each float mechanism is composed of two float components spliced ​​together. Four locking parts are installed on two adjacent float components.

[0008] A tension spring assembly is provided between two adjacent float mechanisms. Both ends of the tension spring assembly are threadedly connected to threaded sleeves, and the threaded sleeves are fixedly embedded on one side of the adjacent float assembly.

[0009] Furthermore, the foam sleeve is made of microporous foamed polypropylene, which can provide buoyancy.

[0010] Furthermore, each of the aforementioned float assemblies includes a semi-cylinder, and a threaded sleeve is fixedly embedded on one side of the outer wall of an adjacent semi-cylinder. The semi-cylinder is provided with a plurality of anti-slip teeth on the outer wall of the foam sleeve, and the anti-slip teeth abut against the outer wall of the foam sleeve. Mounting plates are fixedly connected to both sides of the outer wall of the semi-cylinder. The anti-slip teeth increase the friction of the semi-cylinder and prevent slippage.

[0011] Furthermore, each of the aforementioned locking components includes a first connecting bolt, which extends through two adjacent mounting plates. A nut is threaded onto the outer surface of the first connecting bolt, and the first connecting bolt and the nut cooperate to lock and fix the two adjacent mounting plates.

[0012] Furthermore, a reinforcing sleeve is fixedly fitted onto the outer surface of several of the threaded sleeves, and the reinforcing sleeve is integrally designed with the adjacent semi-cylinder, thereby increasing the connection strength between the threaded sleeve and the semi-cylinder.

[0013] Furthermore, each of the aforementioned tension spring assemblies includes a tension spring body, with connecting blocks fixedly connected to both ends of the tension spring body. Two connecting blocks are rotatably connected to a second connecting bolt at one end of the semi-cylinder, and the second connecting bolt is threadedly connected to an adjacent threaded sleeve. The cooperation between the second connecting bolt and the threaded sleeve facilitates the assembly and disassembly of the tension spring body.

[0014] The beneficial effects of this utility model are:

[0015] In use, this utility model, through the setting of foam sleeve and modular float mechanism, enables the cable to have excellent buoyancy and tensile strength. The foam sleeve provides basic buoyancy, the float assembly enhances the overall buoyancy and distributes the load, the tension spring assembly between adjacent floats buffers wave impact, the anti-slip teeth ensure that the float assembly and the foam sleeve fit tightly, the locking part and the reinforcing sleeve improve the connection strength, the bending section design makes the cable flexible to adapt to dynamic waters, the overall structure is lightweight and durable, and it is suitable for harsh environments such as offshore wind power.

[0023] like Figures 1-3 As shown, a high-strength lightweight cable is disclosed, comprising a cable body 1, with a foam sleeve 2 fixedly sleeved on the outer surface of the cable body 1. The foam sleeve 2 is made of microporous foamed polypropylene, which is assembled on the outer surface of the cable body 1 by a foaming extrusion process, and has excellent weather resistance, UV resistance and hydrolysis resistance.

[0024] Several float mechanisms are fixedly sleeved on the outer surface of the foam sleeve 2. The foam sleeve 2 and the cable body 1 form a curved section with a margin between adjacent float mechanisms. Each float mechanism is spliced ​​from two float components 3. Each float component 3 includes a semi-cylinder 31, and a threaded sleeve 6 is fixedly embedded on the outer wall of one side of the adjacent semi-cylinder 31. The semi-cylinder 31 is provided with several anti-slip teeth 33 on the outer wall of one side of the foam sleeve 2, and the anti-slip teeth 33 abut against the outer wall of the foam sleeve 2. Mounting plates 32 are fixedly connected to the outer walls on both sides of the semi-cylinder 31. Two mounting holes are symmetrically opened on the mounting plates 32.

[0025] Two adjacent float assemblies 3 are equipped with four locking components. Each locking component includes a first connecting bolt 51, which passes through two adjacent mounting plates 32. The outer surface of the first connecting bolt 51 is threaded with a nut 52, and a washer is attached to the nut 52 to increase the anti-loosening performance after fixing. The surfaces of the first connecting bolt 51 and the nut 52 are treated with anti-corrosion to ensure their service life.

[0026] A tension spring assembly 4 is provided between two adjacent float mechanisms. Both ends of several tension spring assemblies 4 are threadedly connected to threaded sleeves 6, and the threaded sleeves 6 are fixedly embedded on one side of the adjacent float assembly 3. The outer surface of several threaded sleeves 6 is fixedly fitted with reinforcing sleeves 34, and the reinforcing sleeves 34 are integrally designed with the adjacent semi-cylinder 31. Several tension spring assemblies 4 include a tension spring body 41. Both ends of the tension spring body 41 are fixedly connected to connecting blocks 42. Two connecting blocks 42 are located at one end of the semi-cylinder 31 and are rotatably connected to second connecting bolts 43. The second connecting bolts 43 are threadedly connected to the adjacent threaded sleeves 6. The tension spring body 41, connecting blocks 42, second connecting bolts 43, and threaded sleeves 6 are preferably made of stainless steel, which has excellent corrosion resistance.

[0027] Buoyancy support and wave adaptation:

[0028] The cable body 1 is covered with a foamed sleeve 2 (microporous foamed polypropylene) to provide basic buoyancy. The float assembly 3 is composed of two semi-cylinders 31 spliced ​​together and wrapped around the foamed sleeve 2 to further increase buoyancy.

[0029] A bending allowance is provided between adjacent pontoon structures to allow the cable to bend flexibly with the waves, avoiding breakage due to rigid pulling.

[0030] Modular connection and tensile reinforcement:

[0031] Each semi-cylinder 31 is fixed to the adjacent semi-cylinder 31 by a mounting plate 32 and locking components (first connecting bolt 51, nut 52) ​​to form a stable structure.

[0032] The two ends of the tension spring body 41 are screwed into the threaded sleeve 6 by the second connecting bolt 43 to connect the adjacent float mechanism, which buffers and disperses stress when subjected to tension.

[0033] The integrated design of the reinforcing sleeve 34 and the threaded sleeve 6 enhances the strength of the connection point and prevents cracking.

[0034] Combining anti-slip and cushioning:

[0035] The inner wall of the semi-cylinder 31 is provided with anti-slip teeth 33, which interlock with the foam sleeve 2 to prevent slippage, while allowing slight deformation to buffer the impact.

[0036] Balancing lightweight design with high strength:

[0037] The foam sleeve 2 reduces weight, while the float assembly 3, threaded sleeve 6, and tension spring assembly 4 work together to provide mechanical strength, making the cable lightweight and durable as a whole.
