Technical Field

The invention relates to the technical field of ship lock equipment and facilities, in particular to a sludging system and a sludging method for a top lock head curtain wall bottom plate of a large ship lock.

Background

When a large ship lock operates, silt contained in river water and foreign matters falling from a ship passing through the lock are flushed to dead corners of a head curtain wall bottom plate of an upper lock under the action of water filling flow of a lock chamber and are accumulated on the curtain wall bottom plate, a large number of foreign matter accumulation layers are formed after a long time, influence is brought to ship passing through the lock, and the silt flushing system is researched and provided for solving the problem that the foreign matters are accumulated on the curtain wall bottom plate.

Disclosure of Invention

The invention aims to solve the problems in the prior art, provides a brand-new system and a method for slushing the upper lock head curtain wall bottom plate of the large ship lock to solve the accumulation of foreign matters on the upper lock head curtain wall bottom plate of the large ship lock, and can effectively reduce the influence of silt contained in river water and the accumulation of foreign matters falling off from a passing ship on the passing ship.

In order to achieve the technical features, the invention is realized as follows: the sludging system for the upper lock head curtain wall bottom plate of the large ship lock comprises a water inlet, wherein the water inlet is arranged in an upper lock head door storehouse, the bottom of the water inlet is connected with a pipeline, the pipeline is arranged between the upper lock head door storehouse and the curtain wall bottom plate, the tail end of the bottom of the pipeline is connected with a sludging pipe, and a plurality of nozzles are arranged on the sludging pipe; an electronic control system is also included.

The water inlet is provided with a trash rack.

The pipelines are arranged in parallel, and each pipeline is communicated with the upper gate storeroom and the heavy wall bottom plate respectively.

The pipeline passes through the left and right traffic galleries of the upper gate head and is a seamless steel pipe.

The erosion and deposition pipe is arranged above the bottom plate of the curtain wall and horizontally arranged along the edge of the bottom of the upper gate head curtain wall, and the erosion and deposition pipe is a seamless steel pipe.

Each pipeline is provided with a working gate valve and a maintenance gate valve respectively; the working gate valve and the maintenance gate valve are arranged in sections where traffic galleries on the left side and the right side of an upper gate head pass through the pipeline are located, the working gate valve is located on the downstream side of the maintenance gate valve, and the working gate valve and the maintenance gate valve are electric gate valves and are respectively connected with an electric control system.

The number of the nozzles is multiple, and the axis of each nozzle forms an included angle of 10-15 degrees with the horizontal plane.

The electric control system is arranged at the upper gate primary site substation and can remotely control the opening and closing of the working gate valve and the overhaul gate valve; and a lock chamber energy dissipation cover plate is arranged on the curtain wall bottom plate.

The silt flushing method of the silt flushing system of the top lock head curtain wall bottom plate of the large ship lock comprises the following steps:

when the ship lock is in an ascending state, the upper lock head door storehouse where the water inlet of the silt flushing system is located is in an upstream water level, the curtain wall bottom plate where the pipeline outlet is located is in a downstream water level, and the upstream water level and the downstream water level have a difference; after the working gate valve is opened, the pipeline is communicated with the upper gate head storeroom and the curtain wall bottom plate, the hydraulic potential energy of river water in the upper gate head storeroom is converted into kinetic energy in the pipeline, high-speed water flow is ejected from the nozzle, and foreign matters at the position of the curtain wall bottom plate are flushed to the position close to the energy dissipation cover plate of the gate chamber; when the ship lock is in a descending state, the lock chamber drains water, foreign matters near the energy dissipation cover plate of the lock chamber are sucked away, enter the water delivery gallery and flush the water delivery gallery below the ship lock, and the foreign matters are prevented from being accumulated on the bottom plate of the curtain wall.

The operation method of the sluicing system of the top lock head curtain wall bottom plate of the large ship lock comprises the following steps:

step 1: when the gate chamber is at the upstream water level, remotely controlling to open the working gate valve at the site substation;

step 2: closing the upstream miter gate, draining the lock and flushing the silt of the silt flushing system;

and step 3: when the ship lock is filled with water, the pipeline of the silt flushing system is in an open state, so that foreign matters are prevented from being accumulated on the bottom plate of the heavy wall;

and 4, step 4: draining the ship lock, sucking foreign matters near the lock chamber energy dissipation cover plate away, entering a water delivery gallery, and flushing the foreign matters to a navigation channel below the ship lock;

and 5: when the work of the silt flushing system needs to be stopped, the lock chamber is filled with water to the upstream water level, and the working gate valve is closed;

step 6: when the working gate valve breaks down, the maintenance gate valve is closed to perform maintenance on the working gate valve.

The invention has the following beneficial effects:

1. according to the invention, the foreign matters at the bottom plate of the curtain wall are impacted by the hydraulic potential energy formed by the fall between the upstream and the downstream during the operation of the ship lock, so that the foreign matters are prevented from being accumulated at the bottom plate of the curtain wall, and the foreign matters impacted by the sluicing system to the vicinity of the energy dissipation cover plate of the lock chamber are absorbed by the normal operation flow of the ship lock when the ship lock drains water, enter the water delivery gallery and flush the water delivery gallery to the navigation channel below the ship lock, so that the influence of silt contained in river water, the leaning handle dropped by the ship passing through the lock, and the like, accumulated at the bottom plate of.

2. The working gate valve and the overhaul gate valve of the erosion and deposition system can be remotely opened at the on-site substation, so that the labor intensity of the operation of the erosion and deposition system is reduced, and the convenience of the operation is improved.

3. Each pipeline of the sluicing system is provided with a working gate valve and a maintenance gate valve, and when the working gate valve breaks down, the maintenance gate valve can be closed to isolate river water from an upper door warehouse, so that the normal operation of a ship lock is prevented from being influenced.
