Description

Technical Field

[0001] This utility model relates to the field of cable technology, and in particular to an acid and alkali resistant cable. Background Technology

[0002] A cable is an electrical device used to transmit electrical energy or signals. The structure of a cable typically includes a conductor layer, an insulation layer, and a sheath layer. The sheath layer not only protects the conductor and insulation layer inside the cable from mechanical, chemical, and environmental damage, but also provides electrical insulation and fire resistance.

[0003] In industries such as chemical engineering, metallurgy, food processing, and wastewater treatment, acid- and alkali-resistant cables are required to resist acid and alkali corrosion and ensure the stability of power and signal transmission. During the laying and use of acid- and alkali-resistant cables, mechanical damage to the sheath layer often occurs. Currently, the repair methods for cable sheath layers generally include repair with insulating tape, heat shrink tubing, and waterproof adhesive. Although these repair methods can repair the cable sheath layer, they are usually difficult to restore the original acid and alkali resistance of the cable. Therefore, the entire cable needs to be replaced, but replacing the entire cable is time-consuming, labor-intensive, and has a long maintenance cycle.

[0004] Therefore, this application provides an acid and alkali resistant cable to solve the problems mentioned in the background art. Utility Model Content

[0031] The present invention will be further explained below with reference to specific embodiments.

[0032] like Figures 1-6As shown, this embodiment provides an acid and alkali resistant cable, including conductors 1, with multiple conductors, at least two, depending on the actual application requirements. Each conductor 1 has an insulation layer 2 wrapped around its outer surface. The insulation layer 2 is made of polytetrafluoroethylene (PTFE), which improves the insulation and chemical corrosion resistance of the conductor 1. A filling layer 3 is provided between the multiple conductors 1 outside the insulation layer 2. The filling layer 3 is made of polypropylene fiber rope, filling the gaps inside the cable, making the cable structure more compact, preventing the internal structure from loosening when the cable is bent or stretched, and improving the cable's mechanical properties, electrical insulation performance, and corrosion resistance. The filling layer 3 is wrapped with a total wrapping layer 4, which is made of cable non-woven fabric. The total wrapping layer 4 is wrapped with an inner lining layer 5, an armor layer 6, and a sheath layer 7 in sequence. The liner 5 is formed by extruding polyvinyl chloride (PVC), and the armor layer 6 is made of steel wire armor, which has high strength and hardness, reducing the impact of mechanical force on the cable. The sheath layer 7 is made of polytetrafluoroethylene (PTFE), which has excellent chemical corrosion resistance and can resist the erosion of chemicals such as strong acids, strong alkalis, and organic solvents. The outer periphery of the sheath layer 7 is fitted with a removable sleeve 8, which is made of insulating silicone rubber. Insulating silicone rubber has good acid and alkali resistance, high mechanical strength, good flexibility and elasticity, providing effective protection for the sheath layer 7 and armor layer 6 inside the sleeve 8, effectively preventing damage to the sheath layer 7, improving the overall performance of the cable, and the sleeve 8 is set in multiple sections. When any section is mechanically damaged, it can be directly replaced, saving time and effort and shortening the cable maintenance cycle.

[0033] like Figure 2 , Figure 5 and Figure 6 As shown, in this embodiment, the sleeve 8 includes a tube body 81. A first snap-fit ​​block 82 and a second snap-fit ​​block 83 are respectively provided at both ends of the longitudinal opening of the tube body 81. The tube body 81, the first snap-fit ​​block 82 and the second snap-fit ​​block 83 are integrally formed. A snap-fit ​​element 821 and a snap-fit ​​groove 831 are respectively provided on the opposite surfaces of the first snap-fit ​​block 82 and the second snap-fit ​​block 83. The snap-fit ​​element 821 is adapted to the snap-fit ​​groove 831. The snap-fit ​​element 821 includes a square strip 822. One end of the square strip 822 is connected to the tube body 81, and the other end of the square strip 822 is provided with a semi-cylinder 823. The snap-fit ​​groove 831 includes a square opening groove 832 provided on the end face of the second snap-fit ​​block 83. The square opening groove 832 extends into the second snap-fit ​​block 83 and communicates with the semi-circular groove 833. The semi-circular groove 833 is adapted to fit the semi-cylinder 823, and the square opening groove 832 is adapted to fit the square strip 822.

[0034] like Figure 3 , Figure 4As shown, in this embodiment, a circular convex circle 84 is provided on one end face of the tube body 81, and a circular groove 85 is provided on the other end face of the tube body 81. The convex circle 84 is adapted to the groove 85. A column 86 is provided on one end face of the first snap-fit ​​block 82 and the second snap-fit ​​block 83. The column 86 and the convex circle 84 are located on the same side. A column groove 87 is provided on the other end face of the first snap-fit ​​block 82 and the second snap-fit ​​block 83. The column groove 87 is adapted to the column 86. The column groove 87 and the groove 85 are located on the same side.

[0035] This utility model also provides a working principle for an acid and alkali resistant cable: the sleeve 8 is made of insulating silicone rubber. Due to its good flexibility and elasticity, the first snap-fit ​​block 82 and the second snap-fit ​​block 83 in the sleeve 8 can be opened during use, and the tube body 81 can be fitted onto the outer periphery of the cable sheath layer 7; then, the semi-cylinder 823 in the snap-fit ​​member 821 is nested into the semi-circular groove 833 in the snap-fit ​​groove 831, and then the square strip 822 is fitted into the square open groove 832, with the opposing surfaces of the first snap-fit ​​block 82 and the second snap-fit ​​block 83 completely abutting; thus completing the wrapping of the outer periphery of the sheath layer 7 by the sleeve 8. To facilitate inspection and maintenance, the sleeve 8 is provided in multiple sections, making... During installation, the convex circles 84 on the opposite sides of the two sleeve sections 8 are nested in the grooves 85, and the column 86 is nested in the column grooves 87. The opposite side ends of the two sleeve sections 8 abut against each other, completing the installation between the sleeve sections 8. When the sleeve section 8 is damaged in order to protect the cable sheath layer 7, the convex circle 84 is disengaged from the groove 85, the column 86 is disengaged from the column groove 87, and the snap fastener 821 is disengaged from the snap fastener groove 831 to replace the damaged section. The sleeve section 8 can effectively resist external damage to the cable sheath layer 7, ensuring the normal operation of the cable. When the sleeve section 8 is damaged, the corresponding damaged section can be quickly removed. The operation is simple, time-saving, labor-saving, and shortens the cable maintenance cycle.
