Caisson type lock head centralized water delivery system
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.
本发明公开了一种沉箱式闸首集中输水系统，包括分离式结构的闸首，闸首由左右两个沉箱组成，沉箱内均设有输水廊道和消能室，输水廊道与消能室固定连接，消能室沿其长度方向固定设有从下到上呈阶梯状水平等间隔排列的多组消力梁，每组消力梁上均固定连接有竖直设置的消力墩，多组消力墩沿消能室宽度方向从前到后呈阶梯状竖直等间隔排列设置，消能室的出水口端部设有消能通道，消能通道的端部固定设有消能盖板。本发明在沉箱内的消能室包含了呈阶梯状的消力梁和消力墩，能与出水口处的消能盖板相结合有效的调整横向和竖向流速分布均匀；消能室的消能盖板大大减少了闸室内水流的紊动，增加了闸室内水面的稳定性。
