The invention relates to hydraulic structures, in particular to shipping locks.

The feed distribution system of the shipping lock is known to contain and feed galleries connected to the upper and lower pools and intermediate galleries have distribution holes, the intermediate galleries being equal in length and arranged symmetrically along the length of chamber 1.

The disadvantage of this system is the unfavorable conditions for the separation of vessels by ensuring a uniform flow of water throughout the chamber.

The aim of the invention is to improve the conditions for the separation of vessels by ensuring a uniform flow of water throughout the entire area.

The goal is achieved by the fact that the distribution system of the supply lock of the navigation lock is contained, and the supply galleries connected to the upper and lower pools and intermediate galleries have, they distribution holes, while the intermediate galleries are equal in length and are located symmetrically along the length of the chamber, intermediate The galleries are located along the axis of the gateway, one after the other, and each of them is connected to one of the food galleries in its middle section.

FIG. 1 shows a double-stranded shipping gateway with the proposed feeding system (one strand is shown in plan-section along the galleries); in fig. 2 - the same, longitudinal section along the axis of the chamber; in fig. 3 is a section A-A in FIG. one; in fig. 4 is a section BB in FIG. one.

The distribution gateway of the shipping gateway includes a water intake 1 with valves 2, located in the upper heads 3 galleries 4 of the feed, connected to the upper and lower pools and to intermediate longitudinal galleries 5 located along the entire length of chamber 6, in their middle parts with openings 7 only with one

from the power supply galleries 4, and with camera 6 through distribution holes 8 of the same shape and cross-section over the entire area of the bottom. Distribution holes 8 are located in equal sections 9, which allow to obtain equal head and flow rates. The power galleries 4 are connected to the downstream through inlets 10 in the lower heads 11 with the closures 12.

Distribution system feed gateway works as follows.

When filling the chamber 6, the closures 12 from the downstream are closed, and the closures 2 from the upstream are open and water enters the feeding galleries 4, then through the openings 7 enters the intermediate longitudinal galleries 5 and through the distribution openings 8 enters the chamber 6 through all sections 9 with equal heads and costs. When the chamber is emptied, the closures 2 are closed, and the closures 12 are opened and the water from the chamber 6 goes through the distribution holes 8 to the longitudinal intermediate galleries 5, then goes to the power galleries 4 and through the outlets 10 in the lower heads 11 is dumped to the lower reach.

 The proposed shipping feed distribution system provides a constant hydraulic and hydrodynamic conditions over the entire area of the chambers and ideal conditions for the rest of the chambers,. vessels, at which it is possible to significantly increase the filling and emptying costs, the rate of change of the water level in the chambers and significantly reduce the filling and emptying time.

FIG. 1-4 shows the minimum section of galleries 4 and 5 for each thread. In relation to the conditions of any other specific gateway, there may be a different number of them, but necessarily in a paired combination, i.e., each galleria of food can be connected to only one

0 intermediate gallery of the proposed type.
