A double-layer water delivery system for ship locks with vertically penetrating water outlets at the bottom of the lock

Abstract

A double-layer water delivery system for a ship lock with longitudinally penetrating water outlet at the bottom of the lock, comprising a ship lock chamber, a first diversion port, a middle branch corridor, a second diversion port, main water delivery corridors located on both sides of the ship lock chamber, respectively The water filling valve and the water discharge valve are located upstream and downstream of the main water delivery corridor. The main water delivery corridor is connected to the inlet of the first diversion port through a T-shaped pipe, and the outlet of the first diversion port is connected to the first diversion port through the middle branch corridor. The two diversion ports are connected, the second diversion port is connected to the third diversion port on the upper floor through the vertical shaft, the third diversion port is connected to the water outlet branch corridor, the water outlet branch corridor is connected to the water outlet hole, and the upper part of the water outlet hole is provided with an energy dissipation cover , the elevation of the first diversion port, the middle branch corridor and the second diversion port are consistent with the elevation of the discharge valve, and the third diversion port, water outlet corridor, water outlet hole and energy dissipation cover are located at the bottom of the sluice chamber. The invention can improve the pressure characteristics of the diversion port to avoid cavitation and cavitation erosion, can also disperse the outflow to the greatest extent, and improve the safety and efficiency of water delivery of the ship lock.

Description

technical field [0001] The invention relates to the technical field of water conservancy engineering, in particular to a double-layer water conveyance system for ship locks with vertically penetrating water outlets at the bottom of the locks. Background technique [0002] In order to overcome the water level difference caused by the construction of reservoir dams on navigable rivers, navigable structures, most commonly ship locks, need to be built. The operating principle of the ship lock is: through the water delivery system buried on both sides or bottom of the lock chamber, the lock chamber is filled and discharged with water, so that the water level of the lock chamber is equal to the water level of the upstream and downstream, and the ships docked in the lock chamber rise with the filling and discharging water. Or down, so as to overcome the water level difference formed by damming, and realize the upward and downward movement of the ship. [0003] The water conveyance...

AI Technical Summary

Problems solved by technology

[0007] In order to solve the problem of the worse cavitation characteristics of the water flow at the diversion port and the berthing conditions of the ship in the lock chamber caused by the greater water delivery energy of the ship lock, the present invention provides a double-layer water delivery system for the ship lock with longitudinally penetrating water outlet at the bottom of the lock. On the one hand It can greatly improve the pressure characteristics of the diversion port to effectively avoid cavitation and cavitation erosion. On the other hand, it can disperse the outflow to the greatest extent, improving the safety and efficiency of water delivery in the ship lock.
