Description

:one

The invention relates to river sluices and to pre1 for the passage of water transport under small-sized bridges.

Known river gateways, including a camera located under the bridge with a gate.

The purpose of the invention is to reduce the level of the DRIVER in the lock room gateway to ensure the passage under the bridge of the ship, as well as to increase the effect and fill the chamber through the gate.

For this purpose, the measure is that it is bled by a discharge pipeline, which is led downstream to a level below the discharge level in the chamber. In addition, the gate is equipped with a baffle visor.

The drawing shows a lock gate, longitudinal section.

The gateway includes a chamber 1, under the bridge 2. The chamber consists of a device 3, tank walls 4, equipped with mooring floats 5 and end walls 6. End walls 6 she-bzheny Prohod and gates 7, associated with lifting mechanisms , for example, with an electric motor, and contain fenders 5. The chamber / is equipped with a discharge pipeline 9, which is led along the river flow to the water level in the river, below the discharge level in the chamber.

The gateway works as follows.

Gate 7 and the fender visors 8 associated with them are located in the extreme lower floor, the upper ends of which are below the river water level at a depth sufficient to pass any waterways. The upper ends of the side walls 4 are above the river water level and indicate the gateway position, can be equipped with signal lights M}, and the berths 5, the slides are connected to the side walls 6 and 6 are in position on the surface of the water level.

The water transport from the river bed freely enters the gateway and moors to the main float 5. At the control station, a button is pressed, from which the lifting mechanisms of the passage gate are activated 7.

The latter, together with the chippers 8, rise above the level of the river's water and the lifting mechanisms are turned off, for example, by Kantsev's switches. Reception: the gateway measure is isolated from the river bed. The volume of water in the lock chamber flows out through pipeline 9 and a minimum water level is set in the chamber, followed by a mooring float 5 and water transport at the same time. The outflow of a certain volume of water from the receiving chamber of the lock into the river and the rate of its discharge are due to

the difference of water columns at the ends of the pipeline 9, as well as the diameter of the pipeline. Further, the waterway “Opportunity” departs from the primary, floating 5, its passage passes the bridge and moors to another mooring shop 5 behind the bridge.

At the station installed on this mooring float 5, a button is pressed, which activates the lifting mechanisms operating in the reverse direction, i.e., lowering gates 7. Through descending through their upper edges, the chamber is filled gateway with water, the flow of which is withdrawn and directed from the battle | visors 8. Passage (gate 7 s from (stowed visors 8 are completely lowered into the lower section, the lower position and the lifting mechanisms are turned off).

The water transport is freed from the mooring float 5 and continues its movement.

Claims (2)

1. Gateway, B1 switching camera located under the bridge with a gate on the heads of the gateway, characterized in that, in order to lower the water level in the lock chamber to ensure passage under the bridge of the vessel, the chamber is equipped with a discharge pipe leading downstream to the water level the river below the rim level in the chamber-re. 2. The gateway according to claim 1, characterized by the fact that, in order to trap the efficiency of filling the chamber through the gate, the latter are provided with fender visors. / W / ldH W J: w- $ y W O W 0
