Description

Technical Field

[0001] This utility model belongs to the technical field of auxiliary equipment for cable processing, and specifically relates to a rapid cooling device for wire and cable production. Background Technology

[0002] In high-rise office buildings or places with high waterproofing requirements, water immersion sensing ropes are installed. Water immersion sensing ropes are contact detection elements and are an important component of water immersion sensors. Water immersion sensing ropes generally use two cables as detection electrode lines. The outer surface of the two detection electrode lines is covered with conductive grease on the metal wires, and the two conductive greases are insulated by air. The conductive grease has a certain degree of water absorption.

[0003] The outer surface of a normal power transmission cable is an insulating layer, which is waterproof. During processing, the waterproof cable insulation layer is coated with a film and then cooled by water immersion. However, when producing water immersion sensing ropes, a conductive metal wire coating machine (wire coating machine) is used. The conductive metal wire is coated with conductive grease to form the water immersion sensing rope. After each conductive metal wire is coated with conductive grease, it needs to be individually air-cooled. If the production volume of water immersion sensing ropes needs to be increased, not only is it necessary to add cable conductive grease coating equipment, but each of these machines also needs an additional air-cooling device. The different cooling environments of different cooling equipment not only affect the stability of quality but also the sensitivity of water immersion sensing. Existing equipment cannot meet the requirements of mass production and the need for cooling in the same environment. Summary of the Invention
