Description

Technical Field

[0001] This utility model relates to the field of power cable technology, and in particular to a power cable with a protective structure. Background Technology

[0002] In modern society, electricity supply is of paramount importance. Power cables, as key carriers for transmitting and distributing electrical energy, are widely used in urban underground power grids, power plant lead-out lines, internal power supply in industrial and mining enterprises, and underwater transmission lines across rivers and seas. With the continuous growth in electricity demand, power cables need to operate stably; however, their complex and diverse operating environments place stringent demands on their protective performance.

[0003] Existing power cables are susceptible to damage from rodents and ants during installation and use, and their surfaces are prone to accumulating debris and dust, which accelerates cable aging over time.

[0004] Therefore, a power cable with a protective structure is proposed. Utility Model Content

[0005] In view of this, the present invention aims to provide a power cable with a protective structure to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial alternative.

[0006] The technical solution of this utility model embodiment is implemented as follows: A power cable with a protective structure includes a main body, a protective cleaning mechanism disposed on the outer wall of the main body, and an installation mechanism disposed at the bottom of the main body. The main body includes: a polyvinyl chloride sheath, a hardened textured layer disposed on the outer wall of the polyvinyl chloride sheath, microcapsules disposed inside the polyvinyl chloride sheath, and natural insect repellent material disposed inside the microcapsules; the protective cleaning mechanism includes a protective sleeve disposed on the outer wall of the polyvinyl chloride sheath, a silicone head disposed on the outer wall of the protective sleeve, a cleaning brush disposed inside the protective sleeve, a cleaning groove disposed inside the protective sleeve, mating rings disposed on both sides of the protective sleeve, and a scraping ring disposed on one side of the mating ring.

"Below," "below," and "under" the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0027] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0028] Example 1:

[0029] like Figure 1-5As shown, a power cable with a protective structure includes a main body 100, a protective cleaning mechanism 200 sleeved on the outer wall of the main body 100, and an installation mechanism 300 snapped onto the bottom of the main body 100. The main body 100 includes: a polyvinyl chloride sheath 101, a hardened textured layer 102 adhered to the outer wall of the polyvinyl chloride sheath 101, microcapsules 103 encased inside the polyvinyl chloride sheath 101, and natural insect repellent material 104 filled inside the microcapsules 103. The protective cleaning mechanism 200 includes a protective sleeve 201 sleeved on the outer wall of the polyvinyl chloride sheath 101, a silicone head 202 adhered to the outer wall of the protective sleeve 201, a cleaning brush 204 adhered inside the protective sleeve 201, a cleaning groove 205 opened inside the protective sleeve 201, mating rings 203 installed on both sides of the protective sleeve 201, and a scraping ring 206 installed on one side of the mating rings 203.

[0030] In this embodiment, the PVC sheath 101 of the main structure not only has a hardened textured layer 102 on its outer wall, but also tightly wraps a metal armor bag 105 inside. The metal armor bag 105 is made of galvanized steel strip or steel wire, which can greatly enhance the tensile and impact resistance of the cable and effectively resist the damage of external mechanical forces to the internal structure of the cable. A polyethylene isolation sleeve 106 is nested inside the metal armor bag 105. The polyethylene material has excellent chemical corrosion resistance and insulation, which can prevent electrochemical corrosion between the metal armor bag and the internal structure, and further block the intrusion of external moisture and impurities. A lead sheath isolation layer 107 is attached to the inner wall of the polyethylene isolation sleeve 106. The lead sheath has excellent sealing and impermeability, which can completely block the entry of harmful substances such as moisture and oil into the core area of ​​the cable, providing reliable moisture-proof and corrosion-proof protection for the internal conductive structure. The inner wall of the lead sheath isolation layer 107 is filled with insulating shielding filler. Layer 108, the filling layer, is made of a mixture of glass fiber and insulating resin. It not only fills the internal gaps and makes the cable structure more compact, but also shields against external electromagnetic interference, ensuring the stability of power transmission. Multiple insulators 109 are evenly distributed inside the insulating shielding filling layer 108. The insulators 109 are made of cross-linked polyethylene, which has high insulation strength and high temperature resistance, and can effectively isolate the conductor from the external structure to prevent leakage accidents. The insulators 109 are wrapped with an inner shielding layer 110, which is made of semi-conductive material. This makes the electric field distribution on the conductor surface more uniform and avoids the insulation breakdown caused by excessive local electric field strength. A conductor 111 is set in the center of the inner shielding layer 110. The conductor 111 is made of high-purity copper or aluminum core, which has excellent conductivity and can transmit electrical energy efficiently. At the same time, the surface of the conductor is polished to reduce resistance loss during current transmission.

[0031] In this embodiment, the installation mechanism 300 includes an installation plate 301 that is snapped onto the bottom of the polyvinyl chloride sheath 101, and a limiting groove 302 formed inside the installation plate 301. A silicone rod 303 is glued to the top of the installation plate 301, and installation angle irons 304 are installed on both sides of the bottom of the installation plate 301. Fixing rods 305 are installed at both ends of the installation angle irons 304, and an installation piece 306 is installed at one end of the fixing rod 305. After multiple cables are placed inside the different limiting grooves 302 on the top of the installation plate 301 of the installation mechanism 300, they are limited by the silicone rods 303. After being hoisted by the fixing rods 305 at both ends of the installation angle irons 304 at the bottom of the installation plate 301, the installation piece 306 at one end of the fixing rod 305 is installed and fixed to the required hoisting position, which facilitates and speeds up the hoisting work.

[0032] In this embodiment: When laying and using the cable, the PVC sheath 101, combined with the hardened textured outer wall layer 102, can improve the overall wear resistance and compression resistance of the cable, and increase the difficulty of rodent and ant gnawing. The natural insect repellent material 104 contained in the internal microcapsules 103 can effectively prevent rodent and ant gnawing. The protective sleeve 201 is fitted onto the outer wall of the cable to form a protective layer. By moving and rotating the protective sleeve 201, the cleaning brush 204 and cleaning groove 205 inside the protective sleeve 201 can easily clean the outer wall of the cable. The docking rings 203 on both sides facilitate the docking of multiple cable segments. The scraping ring 206 can scrape away debris from the outer wall of the cable during docking or movement, ensuring the safety of the cable.

[0033] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
