Embodiment Construction

[0021] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0022] The energy dissipator and its arrangement method described in the present invention are suitable for the centralized water delivery system of ship locks, and the centralized water delivery system of short corridors with grid energy dissipation chambers such as Figure 4 As shown, the centralized water delivery system around short corridors with grid energy dissipation chambers is composed of water inlets on both sides of the corridors, short water delivery corridors on both sides, water outlets on both sides of the corridors, and grid energy dissipation chambers. In this embodiment, the effective size of the lock chamber of the ship lock is 140m×14m×2.5m (length×width×minimum water depth on the threshold); the bottom elevation of the approach channel is 36.00m, and the bottom elevation of the lock chamber is 32.50m; the highest naviga...

Abstract

The invention discloses an inverted K-shaped energy dissipater of a concentrated water conveyance system of a ship lock and a layout method thereof, belonging to the technical field of the hydraulics of the water conveyance system of the ship lock. The whole energy dissipater is arranged in a grille energy dissipating chamber of a ship-lock short-corridor water conveyance system with the grille energy dissipating chamber and is composed of baffle sills, baffle beams and baffle dampers. The two longitudinal baffle sills are symmetrically arranged in front of a left corridor water outlet and a right corridor water outlet of the water conveyance system, a plurality of longitudinal baffle beams are symmetrically arranged in the energy dissipating chamber according to stepped separated holes, and a plurality of longitudinal baffle dampers are arranged under each top-surface grille hole of the energy dissipating chamber; the baffle sills, the baffle beams and the baffle dampers form the inverted K-shaped energy dissipater on the cross section of a lock chamber. The energy dissipater can significantly increase the uniformity coefficient of velocity distribution of the section of the lock chamber and reduce the turbulent fluctuation of water of the lock chamber so as to effectively improve the mooring condition of lock-chamber ships.

Description

technical field [0001] The invention belongs to the technical field of hydraulics of a ship lock water delivery system, and relates to an inverted K-shaped energy dissipator of a ship lock centralized water delivery system and an arrangement method thereof. Background technique [0002] The short corridor water delivery type with grid energy dissipation chamber is widely used in the centralized water delivery system of ship locks. For example, the ship locks of Lianjiang, Gaosha, Danzhu, Mangdao, and Xinglong in my country have adopted this type of water delivery. During the water filling process of the ship lock, often due to the unreasonable arrangement of energy dissipators in the grid energy dissipation chamber, relatively strong turbulent water flow and uneven flow field are easily generated in the lock chamber. This uneven distribution is nothing more than two situations: one is uneven horizontal distribution, and the other is uneven vertical distribution. If the hori...
