Caisson type lock head centralized water delivery system

Abstract

The invention discloses a caisson type lock head centralized water delivery system. The system comprises a brake head body of a separated structure. The lock head is composed of a left caisson and a right caisson. A water delivery gallery and an energy dissipation chamber are arranged in each caisson, the water delivery gallery is fixedly connected with the energy dissipation chamber, and the energy dissipation chamber is fixedly provided with multiple groups of force dissipation beams which are horizontally arranged at equal intervals in a stepped mode from bottom to top in the length direction of the energy dissipation chamber. Each group of force dissipation beams is fixedly connected with force dissipation piers which are vertically arranged, the multiple groups of force dissipation piers are vertically arranged at equal intervals in a stepped manner from front to back along the width direction of the energy dissipation chambers, an energy dissipation channel is arranged at the endpart of a water outlet of each energy dissipation chamber, and an energy dissipation cover plate is fixedly arranged at the end part of the energy dissipation channel. The energy dissipation chambersin the caissons comprise the stepped force dissipation beams and the stepped force dissipation piers, and the stepped force dissipation beams and the stepped force dissipation piers can be combined with the energy dissipation cover plates at the water outlets to effectively adjust transverse and vertical flow velocity distribution to be uniform; the energy dissipation cover plates of the energy dissipation chambers greatly reduces turbulence of water flow in a sluice chamber, and stability of the water surface in the sluice chamber is improved.

Description

technical field [0001] The invention relates to the technical field of ship lock water delivery systems, in particular to a caisson type lock head centralized water delivery system. Background technique [0002] my country's existing nearly 1,000 ship locks basically use centralized water delivery systems. There are two main reasons: 1) The development of my country's inland water transportation industry is slow, and the scale of the ship lock is relatively small, so the time requirement for the filling and discharging time of the ship lock is not high; 2) From the perspective of project cost, the structure of the lock chamber of the centralized water delivery system is simple and the cost Saving; but in the traditional centralized water delivery system, when the ship locks are filled with water, often due to excessive water velocity or strong turbulence, a horizontally uneven flow field is generated, resulting in unequal pressure on both sides of the docked ship; or A vertic...
