Transmission Line Guide Assembly for Curved Duct Installation

The patent replaces manual mechanical handling with an automated advancement device that uses pressurized fluid (water or air) to propel transmission lines through underground ducts. The device includes a propulsion mechanism with nozzles that喷射 pressurized fluid onto the transmission line, and a control system that automatically adjusts pressure and flow rate to advance the line without manual intervention, thereby improving efficiency while maintaining reliability through controlled, damage-free advancement.

The patent utilizes pneumatic and hydraulic principles by employing pressurized fluid (either air or water) to advance the transmission line through the duct. The advancement device incorporates fluid delivery systems with adjustable pressure regulators and flow control mechanisms that enable smooth, controlled propulsion of the transmission line, eliminating the need for manual pulling or pushing while reducing friction and contact stress on the line.

The patent employs dynamic guidance mechanisms within the advancement device that can adapt to changing duct directions in real-time. The device includes adjustable guide arms and flexible positioning systems that respond to the duct's geometry, allowing the transmission line to navigate bends and direction changes without requiring additional access points. The system dynamically adjusts its configuration to follow the duct path, reducing the need for frequent infrastructure interventions.

The advancement device acts as an intermediary between the transmission line and the complex duct system. It incorporates guidance wheels, support rollers, and positioning mechanisms that mediate the interaction between the line and duct walls, enabling the line to follow direction changes smoothly. This intermediary system eliminates the need to create multiple access points, as the device itself adapts to and accommodates the duct's geometric complexity.
