With the accumulation of construction experience with the successive construction of a plurality of ship lifts, the industry experts compiled the national standard "ship lift design code" GB51177-2016 in 2016. In the 'norm', corresponding regulations and requirements are made on the design of metal mechanisms and mechanical equipment, such as the type selection of ship reception chamber working gates (horizontal plane gates, sunken plane gates or sunken arc gates), safety devices (except the horizontal plane gates, mechanical locking devices are arranged at the fully-closed positions of other gate types) and the standard of opening and closing force of opening and closing machines (the opening and closing force is calculated according to the water heads of +/-100 mm to +/-200 mm in the front and at the back of the gates).
The first problem is that: at present, a ship elevator with a horizontal plane gate is adopted in a domestic ship reception chamber, a mechanical locking device is not involved in the opening and closing process of a horizontal door, and the closing stable state of the horizontal door of the ship chamber is kept only by the opening and closing force of an opening and closing machine of the horizontal door.
The second problem is that: according to the design standard of the ship reception chamber falling door hoist, when the downstream of the ship lift is in butt joint, when the water depth in the chamber is higher than the water depth of the downstream, a water drainage flow is started, the ship chamber falling door bears reverse water pressure, and the falling door keeps a closed stable state; when the water depth in the chamber is lower than the water depth of the downstream and exceeds the standard of the opening and closing force (or the pressure is reduced due to the damage of the seal), the hoist will give way, so that the chamber door is partially opened, the water depth of the chamber cannot be normally adjusted, and the condition that the water level of the downstream needs to be relatively stable when the ship receiving chamber is in butt joint with the downstream is determined.
The third problem is that: the method belongs to a daily regulation hub, small amplitude change of unit load causes overlarge downstream water level amplitude and variability, the condition of normal operation of a ship lift (the standard of error water loading depth and the like) cannot be met, a navigation plan needs to adapt to power generation arrangement, the daily operation time is greatly shortened, the requirements of ship lockage and social expectations cannot be met, the satisfaction of people is reduced, and continuous benign development of water transportation economy is not facilitated.
