Design and Research of Ship Carrier for Three Gorges New Ship Locks

Abstract

In view of the long time of passing the ship locks, this paper designs a new type of semi-submersible carrier. This carrier adopts electric propulsion drive, which can carry 4-6 ships at a time through the ship lock, shortening the crossing time; For the electric energy supplement problem caused by the semi-submersible ship adopting the electric propulsion system, this paper has designed a set of ship charging system in the gate. This system realizes the rapid charging during the lifting process of the internal carrier at the gate through the ship-end power receiving device, the shore power supply device and the tension self-sensing cable retracting device. For the lack of security measures and the means of monitoring the bottom of the dirt, this research has designed a new type of ship bottom visual monitoring system, which is realized by setting up a professional imaging device on the semi-submersible ship to collect clear image of the ship bottom, and assists the gate security personnel to realize the rapid and accurate monitoring of the explosives at the bottom of the ship, the damage of the bottom of the ship and the fouling of the ship. For the problem that the current ship support platform is not adaptive to all types of ships is not strong, this work designs an adaptive ship support platform that will be adaptive hydraulic support and semi-submersible The combination of carrier ships enables adaptive support for different ship types, ensuring stability during the process of passing the ship, and reducing the stress concentration at the bottom of the ship.
