(54) СУДОХОДНЫЙ ШЛЮЗ(54) SHIPPING CAP

Изобретение относитс к гидротехническим сооружени м и касаетс конструировани судоходных шлюзов.FIELD OF THE INVENTION The invention relates to hydraulic structures and relates to the design of shipping locks.

Известен судоходный шлюз, содержащий камеру с воротами верхней и нижней голов, оборудованных системами наполнени и опорожнени камеры и пуска воды в камеру 1.A shipping gateway is known, comprising a chamber with gates of the upper and lower heads, equipped with systems for filling and emptying the chamber and launching water into chamber 1.

Недостаток указанного шлюза заключаетс в длительности ввода судов в камеру со стороны нижнего бьефа.The disadvantage of this gateway lies in the duration of the vessels entering the chamber from the downstream.

Цель изобретени - ускорение ввода судов в камеру со стороны нижнего бьефа.The purpose of the invention is to accelerate the entry of vessels into the chamber from the downstream.

Поставленна цель достигаетс тем, что шлюз снабжен эжекторами, продольными и поперечными галере ми, соедин ющими верхний бьеф с нижним, при этом продольные галереи установлены вдоль камеры, а поперечные - в районе верхней головы и соедин ют камеру с продольными галере ми , при этом в местах соединени установлены эжекторы.The goal is achieved by the fact that the gateway is equipped with ejectors, longitudinal and transverse galleries connecting the upper pool with the lower one, while the longitudinal galleries are installed along the chamber, and the transverse - in the area of the upper head and connecting the chamber with the longitudinal galleries. Ejectors are installed at the junction points.

Кроме того, выпуски продольных галерей размещены от нижней головы шлюза на рассто нии не менее 2/3 длины судна.In addition, the issues of the longitudinal galleries are located from the lower head of the lock at a distance of at least 2/3 of the vessel's length.

Судоходный шлюз состоит из камеры 1, верхней головы 2 и нижней головы 3. Шлюз оборудуетс системой наполнени и опорожнени камеры, состо щей из водопроводных галерей 4, затворов 5 и 6, водозаборных отверстий 7 в верховом подходном канале, водовыпусков 8 в камере и водовыпусков 9 в ннзовом подходном канале.The shipping gateway consists of a chamber 1, an upper head 2 and a lower head 3. The gateway is equipped with a chamber filling and emptying system consisting of water galleries 4, closures 5 and 6, water inlets 7 in the upper approach channel, outlets 8 in the chamber and outlets 9 in the lower access channel.

К галере м 4 наполнени камеры примыкают продольные галереи 10, имеющие To the gallery m 4 of the filling chamber adjoin the longitudinal galleries 10, having

10 кажда затворы 11 с верхнего бьефа и затворы 12 с нижнего бьефа. Галере 10 соединена с камерой поперечной галереей 13. В месте примыкани галереи 13 к галерее 10 установлены эжекторы 14. Галереи 10 имеют10 each closures 11 from the upstream and closures 12 from the downstream. Gallery 10 is connected to the camera by the transverse gallery 13. At the junction of the gallery 13 to the gallery 10, ejectors 14 are installed. Galleries 10 have

5 водовыпуски 15 в низовом подходном канале , которые размещаютс на нижней голове 3 на рассто нии более чем 2/3 длины расчетного судна 16.5 water outlets 15 in the lower approach channel, which are located on the lower head 3 at a distance of more than 2/3 of the length of the estimated vessel 16.

Шлюзование судов в камере происходит в обычном пор дке. При наполнении щлюзаThe sluice of ships in the chamber takes place in the usual order. When filling the gate

Claims

20, valves 5 are opened, and water flows from the upper approach channel through opening 7 through galleries 4 and enters chamber 1 through outlets 8. When emptying the gateway, valves b and water are opened through outlets 8, galleries 4 and outlets 9 from chamber 1 lower channel approach. Ships entering and exiting the chamber at the level of the upper reach are made through head 2 in the usual order at a normalized speed, since the depth in the chamber is considerable and the appearance of the piston effect appears to be small. At the downstream level in the lock, vessels are brought in and out into and out of the chamber as follows. When the vessel enters the chamber, the gates 11 and 12 are opened in the galleries 10. The water flows from the upstream to the downstream approach channel. The flow of water passing through the ejector nozzle 14 lowers the pressure in this section of the gallery 10, which leads to suction of water from chamber 1 through galleries 13. Chamber I creates a flow from the lower head 3 to the upper head 2, which coincides with the direction of movement of the vessel 16 The flow rate of water in chamber 1 is controlled by the valves 11 and 12. The outflow of water through the outlet 15 behind the stern of the vessel 16 contributes to the flow towards the chamber 1. When the vessel leaves the chamber 1, the flow in the chamber is created by passing water from the upstream to the head 2 .For secured pass gate 11 is opened, the shutter 12 thus closed. Water from the upper pool fills the gallery 10 and through the transverse gallery 13 enters chamber 1. A chamber is created from head 2 to head 3, 7 / GT / // // y / / y / / y //// f / /// yj / / /) / / T / X / - / - - - - //// L // Xy //// ..Lo ------- Y - (. /r.7 / vv / /// VX / x7xX /// f / fc, i ///// r / ii / ///. 7 ,, y G1G | G | "G1 / G11TZHG THAT corresponds to the direction of movement of the vessel. Use of the proposed Vessel entry and exit systems are permitted in gateways with a leading power system. The technical and economic effect of the device is to reduce the time that ships enter and exit into the chamber. bobbed on locks with a pressure of 8 m and more. Formula 1: An overhead gateway containing a chamber with upper and lower head gates equipped with filling and emptying systems for the chamber and launching water into the chamber, characterized in that in order to accelerate the entry of ships into the chamber from the downstream, it is equipped with ejectors, longitudinal and transverse galleries connecting the upper reach with the lower, while the longitudinal galleries are installed along the chamber, and the transverse galleries are installed in the area of the upper head and connect the chamber with the longitudinal galaxies In addition, ejectors are installed at the junction points.

2. Shipping gateway according to claim 1, characterized in that the longitudinal galleries are disposed off from the lower head of the lock at a distance of at least 2/3 of the length of the vessel.
