Three-stage energy dissipation ship chamber nested in ship lock chamber and ship lockage method

Abstract

The invention relates to a three-stage energy dissipation ship chamber nested in a ship lock chamber and a ship lockage method, which belong 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 three-stage energy dissipation ship chamber nested in the ship lock chamber 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 two ends of the ship chamber body; a plurality of energy dissipation holes used for dissipating and killing water flow energy entering the lock chamber in the water conveying process are formed in the two side walls of the ship chamber body; transverse limiting tires used for consuming transverse dynamic water loads acting on the ship chamber body and transverse impact force ofa ship are arranged on the two sides of the ship chamber body; and longitudinal limiting tires used for consuming longitudinal dynamic water loads acting on the ship chamber body and longitudinal impact force of a ship are arranged on the two sides of the ship chamber body. By designing the three-stage energy dissipation mechanism, the ship chamber has a remarkable energy dissipation effect, the berthing condition of a ship is improved, and the structure of a ship lock water conveying system is simplified.

Description

technical field [0001] The invention belongs to the technical field of design of navigable ship lock hydraulic structures and water delivery systems, and relates to a three-stage energy-dissipating ship box nested in a ship lock chamber and a method for ships passing through the lock. Background technique [0002] With the rapid development of inland shipping, my country has built a number of high-head and large-scale ship lock projects, such as the Three Gorges of the Yangtze River. The five-stage ship lock design has a total head of 113m and a scale of 280m×34m×5m (length×width×minimum water depth on the sill, The same below), Minjiang Jianwei ship lock design head 19m, scale 220m×34m×4.5m, etc. [0003] However, with the increase of the water head and plane scale of the ship lock, the energy entering the lock chamber per unit time during the water transfer process increases exponentially, limited by the initial water depth of the ship lock and the water transfer time, the ...

Problems solved by technology

[0005] There are bound to be some disadvantages in adopting a complex water delivery system, such as: (1) the project cost and construction difficulty are constantly rising; (2) the resistance coefficient of the water delivery system is greatly increased, and at the same time, the opening and closing time of the valve is required to be extended, resulting in water delivery time If it is too long, it will seriously affect the passing capacity of the lock
