AI Technical Summary

Technical Problem

The existing high-head ship lock's inertial water conveyance system is prone to problems such as near-end flow deviation, uneven temporal flow, and excessive local flow velocity, making it difficult to guarantee the uniformity and stability of the outlet branch channel.

Method used

A curved, fully continuous, decentralized water conveyance system is adopted. By setting up a main corridor, branch corridors, deflector channels, distribution holes, and energy dissipation covers underground in the gate chamber, a closed water conveyance space is formed. The system utilizes lateral water flow interconnection and self-balancing mechanisms to improve the uniformity of water flow distribution and the consistency of flow velocity.

Benefits of technology

It effectively reduces near-end flow deviation and alternating flow deviation, improves water conveyance efficiency and ship berthing safety, and meets the stringent operational requirements of high-head, high-flow ship locks.

Abstract

This application provides a curved, fully continuous, decentralized water conveyance system suitable for high-head ship locks, belonging to the field of ship lock technology. The system includes a water conveyance space underground within the lock chamber, comprising a main corridor and several branch corridors. The main corridor is located on one side of the water conveyance space. Several branch corridors are located within the water conveyance space. Branch corridors near the edge have diversion outlets. A flow deflection channel is formed between the branch corridors, and several distribution holes are located between adjacent branch corridors. These distribution holes enhance the lateral flow interconnection capacity, improve the uniformity of flow distribution in each branch corridor, and reduce near-end flow deviation and alternating flow deviation phenomena. The top of the water conveyance space has several outlet holes communicating with the lock chamber. An energy-dissipating cover plate is connected to each outlet hole at the bottom of the lock chamber, forming a flow channel between the energy-dissipating cover plate, the outlet hole, and the bottom of the lock chamber. Through lateral flow interconnection, the water pressure and velocity in each corridor can be automatically balanced, making the flow rate along the passage more consistent and effectively reducing flow deviation and alternating flow deviation phenomena.
