Description

The invention relates to hydraulic structures and is intended to pass vessels.

The purpose of the invention is to increase the capacity of the gateway by reducing the time to fill the ship's chamber.

The drawing shows the proposed gateway.

The gateway contains the top 1 and bottom 2 heads and the ship chamber 3.

The upper head 1 is provided with a main lifting and lowering gate 4 and a quenching chamber 5. This chamber consists of a damping screen 6 and two vertical girder rails 7. One of the gratings is installed directly under the screen 6 and serves as a resistor providing a level difference. The other grid is located at the end of the quench chamber, serves to distribute the flow rates vertically and is also an additional resistance that creates a level difference. Concentrated water supply from the top 1 head to the bottom. 2 is carried out through the water openings of the beam grates 7.

The distribution water supply is carried out through water outlets connected to the ship's chamber and the quench chamber through water galleries 8. located in the bottom or walls of the ship's chamber 3. Water outlets 9 water galleries are located in the central part of the ship's chamber.

A blanking chamber 5 is bounded at the top by a horizontal plate 10, which, like the beam distribution grids, is fixed between the walls of the ship's chamber and rests on two vertical bulls.

The gateway works as follows.

The main lifting and lowering gate 4 is closed and hold the head of the upstream. In order to fill the ship chamber 3, the gate 4 of the upper head 1 rises upwards, opening an opening for the entry of water into the quench chamber 5, followed by the entry into the ship chamber through the outlets 9 located between the beams of the distribution grids 7 and the outlets 9 of the water galleries 8 located in the bottom or walls of the ship's chamber 3.

For the ship entering the lock, the gate 4 of the upper head 1 is lowered into a niche between

fall wall and damping screen 6 after filling the ship's chamber. For emptying the chamber 3, the gate 4 is returned to its original position, after which water is discharged into the lower pool through the culvert holes of the lower head 2. The gate of the lower head 2 is opened, and the vessel leaves the chamber 3. After closing the gate of the lower head 2, the cycle is repeated.

Claims (1)

The lifting gate is located between the damping screen 6 and the wall 10. Formula of the invention The shipping gateway containing the chamber, the lower head and the upper head with five lifting and lowering the gate and the wall and, in order to increase the capacity of the gateway by reducing the time to fill the chamber, the upper head of the gateway is equipped with a blanking chamber, including damping screen, beam distribution grids and a horizontal plate and connected to the ship's chamber by water outlets located between the beams of the distribution grid and in the bottom of the ship's chamber, while the lifting and lowering gates are located between the wall of the fall and the damping screen.
