Double-layer staggered-hole energy dissipation ship chamber for ship lock

Abstract

The invention relates to a double-layer staggered-hole energy dissipation ship chamber for a ship lock, which belongs to the technical field of navigation ship lock hydraulic structure and water delivery system design. The ship chamber is arranged in the lock chamber. The double-layer staggered-hole energy dissipation ship chamber for a ship lock comprises a ship chamber body with an open top, a bollard arranged on the ship chamber body, buoys arranged on two sides of the ship chamber body, and an upper end horizontal door and a lower end horizontal door which are respectively arranged at twoends of the ship chamber body; the ship chamber body comprises an inner layer side wall and an outer layer side wall, the inner layer side wall and the outer layer side wall are provided with a plurality of inner layer energy dissipation holes and a plurality of outer layer energy dissipation holes respectively, and the inner layer energy dissipation holes and the outer layer energy dissipation holes are arranged in a staggered mode. The ship chamber is designed to be of a double-layer side wall structure, and the energy dissipation holes are formed in the double-layer side wall in the staggered mode, so that the ship chamber has a remarkable energy dissipation effect, and the application water head of the ship lock is improved.

Description

technical field [0001] The invention belongs to the technical field of navigable ship lock hydraulic structures and water conveyance system design, and relates to a double-layer staggered-hole energy-dissipating ship compartment for ship locks. Background technique [0002] According to incomplete statistics, there are more than 3,000 ship locks in the world at present, accounting for about 97% of the total number of navigable buildings; among the nearly 900 navigable buildings in my country, ship locks account for about 90% of the total. However, when the water head is higher than 60m, the application of the ship lock is seriously hindered. The Usky-Kaminoarsky ship lock (constructed by the former Soviet Union) with a single-stage maximum water head of only 42m has been built so far. The maximum single-stage water head in my country is 40.25 m Qianjiang Datangxia ship lock under construction. The main reason is that the hydraulic structure of the current ship lock water del...

AI Technical Summary

Problems solved by technology

The main reason is that the hydraulic structure of the current ship lock water delivery system cannot meet the energy dissipation requirements under the condition of super high water head.

The navigable structure that often replaces the ship lock is the ship lift, but compared with the ship lock, the ship lift has its disadvantages, such as the small passing capacity, the docking efficiency of the ship receiving box is greatly affected by the operation of the power station, its own structure and electromechanical equipment are complex, and the operation Huge maintenance workload, etc.
