Description

IMPERIAL

PATEN ^ MT.

The present invention relates to the installation of a shipping lock with folding doors in the upper and lower head and a method for filling and emptying the lock chamber.

According to this invention, the latter should not be carried out by means of lateral circulations with inflow and outflow gates but the water required to fill the lock chamber

ίο is from the head of the lock, through a folding gate arranged in the full width of the chamber between the lock front wall and a prefabricated end wall to the sole. In the lower part there is also the full width of the chamber engaging flap gate together with a throttle valve. By opening the upper gate and closing the lower gate along with the throttle valve, the water rises through rust or

sieve-like openings in a top floor of the lock chamber up to the filling level; as well takes place when the upper gate is closed and the lower gate is opened together with the throttle valve the emptying of the lock chamber to the underwater.

Due to the evenly distributed water supply over the entire surface of the lock chamber the water rises calmly and without undulating movements and undercurrents, so that the ships can rise and fall without being moored. Due to the fast, The inward and outward transfer of the water level is uniform and calm the barges have been shortened considerably and considerable time savings have been achieved.

In the accompanying drawing shows

Fig. Ι a lock in longitudinal section,

Fig. 2 the same in plan,

3 shows a three-stage lock in longitudinal section.

It denotes α the closing gate of the lock in the head; s, S ₁ is an extended front wall of the lock, e the channel-like space between them, which continues along the bottom of the chamber into the underwater; f, f _x are the bottoms enclosing it, of which f _x is perforated like a rust or sieve; b is the throttle valve for the drainage of water from the lock chamber to the underwater; c is the flap gate of the sluice in the lower head; d is a solid closing wall of the lock chamber above the hinged gate in the lower head.

As can be seen, the sluice water with closed gate c and with closed, coupled with it, at the level of the sole f arranged throttle valve b in the lower head through the closing valve α in the head, which is set in a corresponding inclined position and by the double end wall s , S ₁ formed gap e passed to the sole; whereupon it rises through the perforated floor f _x in the lock chamber and fills it, whereupon

the ship to be locked through after the folding gate β has been put down into the chamber can.

When the chamber is emptied, the throttle flap δ and flap gate c are opened, whereupon the water in the chamber drains into the underwater.

This process is repeated several times in the lock staircase shown in FIG. 3.

Claims (2)

Patent Claims: i. Shipping lock with hinged doors in the upper and lower head, characterized in that for the flow of water in front of the upper end wall (s) of the lock chamber a second full wall (S ₁₎ and the massive sole (f) a second rust or sieve-like bottom (JP ₁ ) is built in. 2. A method for filling and emptying ao the lock chamber according to claim i, characterized in that the Schleusenwa, sser when filling the chamber on the head by inclination of the closing gate («) and by the space formed by the double end wall (s, S ₁ ) (e) is directed to the sole and there rises through the perforated floor (/ \) in the chamber, but when emptying the chamber through a throttle valve (δ) arranged in the lower head at the level of the solid sole (f ) and through the lowered flap gate (c) drains into the underwater.
