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 of the present invention are suitable for the centralized water conveyance system of the ship lock, and the short gallery centralized water conveyance system with the grid energy dissipation chamber is such as Figure 4 As shown in the figure, the centralized water delivery system around the short corridor with grille energy dissipation chamber is composed of the water inlet of the corridor on both sides, the short corridor of water delivery on both sides, the water outlet of the corridor on both sides, and the grille energy dissipation chamber. 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 sill); the bottom elevation of the upper approach channel is 36.00m, and the bottom elevation of the lock chamb...

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 ship lock water delivery system hydraulics, and relates to an inverted K-type energy dissipator of a ship lock centralized water delivery system and an arrangement method thereof. Background technique [0002] The short gallery water delivery type with grid energy dissipation chamber is widely used in the centralized water delivery system of ship locks. During the watering process of the ship lock, the layout of energy dissipators in the grid energy dissipation chamber is often unreasonable, and it is easy to generate strong turbulent water flow and uneven flow field in the lock chamber. This kind of uneven distribution is nothing more than two cases: one is uneven horizontal distribution, and the other is uneven vertical distribution. Uneven lateral distribution will generate vertical axis vortices, causing the two sides of the berthing ship to be subjected to large lateral forces due to different press...
