Ship lock dynamic water valve closing process debugging method capable of shortening water filling time

Abstract

The invention provides a ship lock flowing water valve closing process debugging method capable of shortening water filling time. The method comprises the following steps that 1, the water level in alock chamber is flush with the downstream water level, a downstream miter gate is closed, and a drain valve is closed; 2, a water filling valve is opened to fill water until the water filling valve isin a fully open state; 3, when the residual water head value reaches H, a water filling valve is started to be closed, when the water filling valve is closed to the opening degree n, the valve closing action is stopped, water filling is continued till the water level of the lock chamber is flush with the upstream water level of the ship lock, the miter gate is opened to the end of opening, and the waiting flush time delta(t) value and the inertia ultrahigh value delta(h) are calculated; 4, according to the delta(t) value and the delta(h) value, the remaining water head value delta(H) or the valve closing opening value delta(n) of the water filling valve is adjusted; 5, repeating the step 1 and the step 3 for debugging by adopting the adjusted delta(H) and n values, and synchronously calculating delta(t) and an inertia ultrahigh value delta(h). The process for closing the valve by moving the water in advance of the valve can ensure the running of the miter gate and the berthing safetyof a lock chamber ship, and can shorten the water filling time.

Description

technical field [0001] The invention relates to the technical field of ship lock hydraulics, in particular to a ship lock dynamic water closing valve process debugging method for shortening the water filling time of a ship lock in a decentralized water delivery system. Background technique [0002] During the water filling process of the ship lock, the general operation mode of the water delivery valve is as follows: (1) The initial opening of the valve is 0 (fully closed state) and it is opened to the opening of 1 (fully open state), and the valve is kept in the fully open state; (2) After the water level on both sides of the miter door is equal, the miter door is continuously opened from the fully closed state to the fully open state, and the valve remains in the fully open state; 1 (full open state) close to opening 0 (full closed state). [0003] The high-head ship locks all adopt a decentralized water delivery system. Due to the complexity of the water delivery system ...

Problems solved by technology

[0003] High-head ship locks all adopt a decentralized water delivery system. Due to the complexity of the water delivery system and the large inertia of the water flow, the water level in the lock chamber at the end of the water delivery has a phenomenon of high inertia

Because most high-head ship locks use miter gates, excessive inertia will push the miter gates open, damage the opening and closing mechanism components of the miter gates, adversely affect the mechanical and electrical equipment of the miter gates, and also endanger the berth at the lock.
