Description

FIELD OF THE INVENTION The invention relates to hydraulic engineering, in particular to shipping locks.

The aim of the invention is to increase the capacity of the gateway.

FIG. 1 shows a chamber, a sluice with a water level at the headwater, a cross section; in fig. 2 - the same, with the water level downstream.

The navigation gate includes a chamber 1j, each wall of which is combined with the wall of the hermetic seal of the reservoir 2 2 is fixed on the bottom of chamber 1 and is made of “3 elastic corrugated ball yarn. In the process of filling or emptying the tanks 2, the rigid boards 3 can be moved relative to the axis of symmetry of the gateway chamber 1, for example, deviating from their original position with the help of a pivoting device 4 fixed to the bottom of the gateway chamber or moving across the gateway chamber parallel to its axis of symmetry. In the mates of the lower ends of the shields 3 with the bottom of the chamber there are elastic waterproof devices 5. The supply of compressed working medium to the tanks 2 is carried out through the air ducts 6.

The shipping gateway works as follows.

When the water level in the chamber 1 of the tank is equal to the level of the lower reach, the tanks 2 are in the folded state on the bottom of the chamber, while the position of the rigid shields 3 corresponds to

water level in the downstream. Vessels enter the chamber, are moored in the usual way. After closing the lower gate of the gateway, the volume of the tanks 2 is increased pneumatically, hydraulically or mechanically, as a result of which the rigid shield-walls 3 are rotated and the geometry of the gateway chamber changes and the water level in the chamber simultaneously rises to the desired level, for example, upstream. When moving the rigid wall panels 8, the locked vessels move along with the rigid

shields-walls, and the required depth under the ships' bottom is provided with horizontal recesses in rigid shields-walls 3.

Vessels coming out of the chamber are produced,

in normal order. The decrease in the water level in chamber 1 is performed in the reverse order, i.e. tank volume

2 shrink, with stiff shields

3 Under the pressure of water in the chamber, the compressed working medium is displaced from the tanks 2, as a result of which they are folded and turn the shields at the right angle.

The possibility of rotation of the rigid wall panels 3 relative to the bottom of chamber 1 with a change in geometry ensures the operation of the navigation interface using water, which is located only in the chamber at the minimum navigable level.
