A double-layer staggered-hole energy-dissipating ship compartment for ship locks

Abstract

The invention relates to a double-layer staggered-hole energy-dissipating ship compartment for a ship lock, which belongs to the technical field of navigable ship lock hydraulic structures and water delivery system design. The bollards on the body of the ship and the buoys arranged on both sides of the body of the ship, and the upper and lower doors respectively arranged at both ends of the body of the ship; the body of the ship includes an inner side wall and an outer side The inner wall and the outer wall are respectively provided with a number of inner layer energy dissipation holes and a number of outer layer energy dissipation holes, and the inner layer energy dissipation holes and the outer layer energy dissipation holes are arranged in a dislocation manner. In the present invention, the ship compartment is designed as a double-layer side wall structure, and energy-dissipating holes arranged in dislocations are designed on the double-layer side wall, so that the ship compartment has a remarkable energy-dissipating effect, and the applied 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 currently more than 3,000 ship locks in the world, 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 Uski-Kaminoalski ship lock with a single-stage maximum water head of only 42m has been built so far, and the Qianjiang River under construction in my country has a single-stage maximum water head of 40.25m. Daito Gorge Ship Lock. The main reason is that the hydraulic structure of the current ship lock water delivery system cannot meet...

Problems solved by technology

However, when the water head is higher than 60m, the application of the ship lock is seriously hindered. The Uski-Kaminoalski ship lock with a single-stage maximum water head of only 42m has been built so far, and the Qianjiang River under construction in my country has a single-stage maximum water head of 40.25m. Daitokyo Ship Lock

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 amount of maintenance work, etc.
