Description

(54) ПЛАВУЧИЙ СУДОПОДЪЕМНИК(54) SWIMMING SHIPS

Изобретение относитс к гидротехническим сооружени м.The invention relates to hydraulic structures.

Известны судоподъемники, содержащие пути с перемещающейс по ним судовозной камерой и передвижные щиты со Бст)эое-чцыми в них воротами 1.11.Ship-lifters are known, containing paths with a ship-carrying chamber moving along them and mobile shields with a Bst gateway in them 1.11.

Недостатком указаггаого судоподъем- ника вл етс сложность конструкции и мала пропускна способность.The disadvantage of this ship lift is the design complexity and low throughput.

Наиболее близким решением из известных вл етс плавучий судоподъемник , содержащий камеру с шарнирами дл ее закреплени , балластные отсеки, затворы и входной оголовок с пазами 2The closest known solution is a floating ship lift, containing a chamber with hinges for fixing it, ballast compartments, gates and inlet head with grooves 2

Недостаток указанного судоподъемника заключаетс в том, что на гидроузлах где имеютс колебани уровн верхнего и нижнего бьефов, высота бортов камеры и ее верхнего затвора должны быть рассчитаны на воспри иие этих колеба ний бьефов.The disadvantage of this ship elevator is that at waterworks where there are fluctuations in the level of the upper and lower pools, the height of the sides of the chamber and its upper gate should be designed for the perception of these fluctuations of pools.

Кроме того, при sst)M увеличиваетс угол поворота камеры относительно ша| ниоа , что усложн ет конструкпию уплотIn addition, when sst) M increases the angle of rotation of the camera relative to the shaft | Nioa, which complicates the design

нени камеры с входным огоЛовком, &. также создает неудобства в работе иэза нарушени балластировки камеры, чт приводит к уменьшению пропускной способности судоподъемшжа.There is no camera with an input fence, &. It also causes inconvenience in the operation of the camera and its ballasting, which results in a decrease in the carrying capacity of the ship.

Дл увеличени пропускной способности судоподъемника и уменьшени веса механического оборудовани камера предлагаемого судоподъемника шарнирно соединена с затвором, установле1шым в пазах входного оголовка.In order to increase the throughput of the ship elevator and reduce the weight of the mechanical equipment, the camera of the proposed ship elevator is pivotally connected to the gate, which is installed in the slots of the inlet tip.

Claims

646О02 The floating ship-lift includes a chamber 1 fixed by means of a horizontal one, about a shayiry 2 to a flat lowering shutter 3, installed in the slots of the inlet tip 4. The seal 5 of the chamber 1 with a flat shutter 3 and the seal 6 of a flat shutter with an inlet tip 4 are implemented in the same way . From the Bep: itoBofl side, chamber 1 is equipped with a working valve, for example, valve shutter 7, from the lower side, the chamber has a blind threshold 8. The height of the nqpora 8 is equal to the minimum depth of water in chamber 1,. On the sides of the chamber 1 is located :. ballast compartments 9, communicating with the upper and lower pools, and the internal water volume of the chamber, the float compartments 10 are located in the Dyoi Dye chamber 1 and the lower sides of the vygrbd Sakh. Cuttings 11 in the sides of the chamber are intended to reduce the time of filling and support: “Water from the lower pool. To keep the chamber 1 from the longitudinal bite when wading in the downstream and to accurately exit the pac4e№bte working positions from the lower side of the Grades, install lifting mechanisms 12, for example, hydraulic lifts. For maneuvering a flat gate 3 at the inlet of the inlet -head 4, there are two integrated hydraulic lifts 13. The floating ship-lift works as follows. To transfer the vessel from the downstream to the upper chamber 1 is set in such a position that the threshold 8 is buried in the water to a depth sufficient for the vessel to pass over it. The shutter 7 of the camera 1 is closed. The shutter 3 is installed in such a position that the upper edge of its passage. . The structure is: at a depth sufficient to allow the vessel to pass over it when it enters the headwater. ; In this half of the chamber 1 of the ball, the compartments 9 are filled with water and bypass the negative buoyancy force which is perceived by the hydraulic lifts. Thus, the chamber is balanced. The vessel enters chamber 1 and is moored. Then, O1K $ S shatsya klspsety connecting the ballast compartments with the lower reach, and at the same time the pump installation of hydraulic lifts is turned on and they begin to work on the rise of the chamber. The chamber begins to float, while the excess water from the chamber through the threshold and through the side notches 11 goes into the lower reach. The chamber is raised until the water level in the chamber is equal to the water level in the upper bay. The threshold of chamber 8, which came out of the water, 1 Holds the estimated volume of water inside the chamber. The worker opens. lock 7, the vessel is removed from the bollard and out into the upper reach. When a ship is transferred from the upstream to the downstream, all operations are performed in reverse order. When the water level in the upstream is changed, for example, when it is raised, the shutter 3 with the aid of hydraulic lifts 13 also rises to a height equal to the rise in the water level in the upstream. At low-pressure hydropower plants, usually, an increase in the water level in the upstream leads to an increase in the water level and in the downstream. In order to connect the elevator to the movable gate, it becomes possible to install it relative to the reach in the most favorable position without additional ballasting. The positive effect of the applications of the present invention is also that it does not require to increase the height of the sides and the chamber and its shutter by an amount equal to the difference between the maximum and the most navigable horizons in the upper reach. This type of ship elevator can be applied in the projects of low-terminal hydroelectric complexes currently under development on transfer routes of the ceBejpifbix rivers to the Volga and ApartfeftKofo river basins. Claims of the invention A floating ship lift, comprising a chamber with hinges for fixing it, ballast compartments, closures and an entry tip with grooves, characterized in that, in order to increase the carrying capacity of the ship lifter and

reducing the weight of the mechanical equipment, the camera lifter is pivotally connected to the bolt, which is installed in the slots of the inlet head.
