Problems solved by technology

Due to the water head difference between the upstream and downstream of the ship lock, the ship cannot pass through continuously, and it will take a certain amount of time to go through the process of ship entering and leaving, gate opening and closing, and lock chamber filling and discharging.
In most cases, the transport capacity of a channel often depends on the passing capacity of the ship lock, and the passing capacity of the ship lock depends to a large extent on the time for the ship to pass the lock. However, the water consumption of ships passing through the traditional ship lock is large, and the water transport of the ship lock The water transfer efficiency of the system is low, resulting in a long time for ships to pass through the lock, which greatly affects the passing capacity of the ship lock

Abstract

The invention relates to an air bag type water filling-emptying auxiliary system for a ship lock, belonging to the field of design of navigation ship lock hydraulic structures. The air bag type water filling-emptying auxiliary system for the ship lock comprises an air bag device arranged on the base plate of a lock chamber, wherein the air bag device comprises an air bag main body, an air bag top plate, an air bag base plate, inflating ducts, inflating pumps and inflating-discharging valves, the air bag main body is arranged between the air bag top plate and the air bag base plate and fixed on the base plate of the lock chamber by the air bag base plate; the air bag base plate is provided with built-in inflating ducts and k air outlets, wherein each two air outlets are connected by one built-in inflating duct; and one end of each inflating duct is connected with one inflating pump by one inflating-discharging valve, and the other end of each inflating duct is connected with one built-in inflating duct to achieve inflating and discharging of the air bag device by the inflating-discharging valve. According to the air bag type water filling-emptying auxiliary system for the ship lock, the water lockage of ships can be effectively reduced, the filling-emptying time of the lock chamber can be shortened, and the lockage efficiency and the waterway transport capacity can be improved; and the air bag type ship lock water filling-emptying auxiliary system can be widely applied to the ship locks in various sizes.

Description

technical field [0001] The invention relates to an auxiliary water filling and discharging system for an airbag type ship lock, which belongs to the field of hydraulic structure design for navigable ship locks. Background technique [0002] Ship locks are the most common navigable structures in inland waterways. They have the functions of increasing the size of the waterway, improving water flow conditions, and communicating water systems. Due to the head difference between the upstream and downstream of the ship lock, the ship cannot pass continuously, and it will take a certain amount of time to go through the process of ship entering and exiting, opening and closing of the gate, and filling and discharging the lock chamber. In most cases, the transport capacity of a channel often depends on the passing capacity of the ship lock, and the passing capacity of the ship lock depends to a large extent on the time for the ship to pass the lock. However, the water consumption of ...
