Description

Technical Field

[0001] The invention relates to the technical field of gravity silt removal at the bottom of a ship lock, and in particular to a river channel ship lock anti-siltation device and a use method thereof. Background Art

[0002] A ship lock is a box-shaped hydraulic structure that is used to ensure smooth passage of ships and concentrate the water level difference on the waterway. In natural rivers, due to the regulation of flow and channelization of navigation, and in canals due to the limitations of terrain conditions and water surface slope, a stepped longitudinal section must be formed to form a concentrated water surface drop. Therefore, special navigation buildings must be used to allow ships to pass through the drop directly. The most commonly used modern navigation building is the ship lock. It is a box-shaped structure consisting of upstream and downstream pilot channels and upstream and downstream lockheads and lock chambers. The ship lock chamber is a box-shaped chamber for mooring ships (or fleets). The water level in the lock chamber is adjusted by filling or draining water in the chamber, so that the ship can be vertically raised and lowered between the upstream and downstream water levels, thereby passing through the concentrated waterway water level difference. When the ship travels from downstream to upstream, the water level in the chamber drops to the same level as the downstream water level, then the gate at the downstream lock is opened, the ship enters the lock chamber, the gate is closed, water is poured in, and when the water level rises to the same level as the upstream water level, the gate at the upstream lock is opened, and the ship can leave the lock and sail upstream through the upstream pilot channel. When the ship travels from upstream to downstream, the lock operation procedure is the opposite.

[0003] During the use of existing ship locks, the opening and closing of the communicating vessels controls the water level of the upstream and downstream lock chambers. The communicating vessels all adopt a long arc-shaped structure. The water in the upstream lock chamber enters the downstream lock chamber through the arc of the communicating vessels. When the water passes through the arc, it is easy to form a vortex at the bottom of the bend, causing part of the silt in the water to be unable to wash out of the arc, causing the silt to accumulate in the communicating vessels, affecting the opening and closing of the gate, causing the gate to be loosely closed, and affecting the navigation speed. At the same time, the bottom of the lock chamber that has been used for a long time will also cause silt to accumulate. The service life of the gate and the communicating vessels is reduced, and the maintenance cost is increased. Therefore, a river channel ship lock anti-clogging device and a method of use thereof are designed to solve the problem of silt accumulation at the bottom of the communicating vessels and lock chambers of the existing channel lock bodies. Summary of the invention

[0004] In view of the problems existing in the prior art, an object of the present invention is to provide a river channel ship lock anti-silting device and a method of using the same.

The gate chamber spoiler mechanisms are provided with spoiler cylinders and inclined bases. The inclined bases are fixedly installed at the bottom of the gate chamber, and spoiler cylinders are fixedly installed on the inclined bases.

The diameter of the horizontal pipeline is smaller than the diameter of the arc pipeline. The horizontal pipeline is connected to the arc pipeline through a reducing pipeline, and the arc pipeline is connected to the vertical pipeline.

[0009] Specifically, a connecting wall is arranged at the bottom of the gate seat, and the connecting wall divides the channel of the communicating vessel into a plurality of water holes, and the number and positions of the water holes are consistent with the number and positions of the disturbing mechanism of the communicating vessel.

[0010] Specifically, a gate plate is provided under the connecting wall, and a plurality of sealing plates are provided on the gate plate. The number and position of the sealing plates are adapted to the water through hole. A gate plate lifting device is installed at the bottom of the gate plate.

[0013] Specifically, the spoiler tube is provided with a plurality of drainage holes.

[0014] A method for using a river channel ship lock anti-silting device comprises the following steps:

The gate plate lifting device 9 adopts a plurality of hydraulic cylinders installed in the sealing cavity, and the top of the cylinder rod of the hydraulic cylinder is connected to the gate plate 7.

[0037] A plurality of lock chamber flow disturbance mechanisms 1 are installed at the bottom of the lock chamber 12 at the channel outlet of the communicating vessel 4.

[0038] The water inlet 1.5 side of the spoiler 1.1 is located on the channel drain outlet side of the communicating vessel 4.

When the water hole 6 is closed, the vertical pipe 2.1, the arc pipe 2.2 and the horizontal pipe 2.3 form a water storage pipe.

[0044] 3. Add a spoiler tube 1.1 to the lock chamber, cast an inclined base 1.4, fix the spoiler tube 1.1 on the inclined base 1.4 by bolts, and fix the water collecting cover 1.2 outside the spoiler tube 1.1 on the wall of the lock chamber 12 by bolts.

[0045] 4. After the water in the channel of the communicating vessel 4 enters the downstream lock chamber, part of the water enters the spoiler tube 1.1 through the water collecting cover 1.2. The spoiler tube 1.1 forms a scouring and disturbing flow on the water body at the bottom of the lock chamber 12 due to the pressure reduction and the function of the drainage hole 1.3.
