DE386929C - Lock gate or weir with a retractable locking body - Google Patents

Description

The invention relates to a lock gate that can be moved up and down under guidance can also be used as a weir, and that for the purpose of exposing the passage accordingly is sunk deep below the water level.

The novelty of the invention is that the movable closure body under the Influence of a continuously effective buoyancy generated by the upper water level from below is pressed firmly against an undercut stop that makes the tight connection of the body conveyed to the masonry. To make it easier to open the gate, or in order to do it automatically, is on or in the correspondingly designed gate body creates a water load either from the upper water or from the rising lower water, which brings the body into the state of the limit float position, so that it can be loaded with more or less load as required, be it with the help of a small additional force, be it by blowing in and letting out can be caused to rise or fall by compressed air. Since in the state of the limit float there is a slight pressure the body is enough to make it sink, so this state can also be used to open the gate automatically when a ship hits a sloping surface to open. Another advantage of the invention is that the closure body

can be exchanged in the event of damage without significant operational disruptions can.

In the drawing, the invention is illustrated in three embodiments, namely they show the Fig. ι to 4 as an upper gate and Figs. 5 and 6 as a lower gate of a lock. In In both cases the gates are opened after the water levels have been reflected. In contrast 7 to 9 show the invention in its use as an upper gate of a lock, even with one-sided Water overpressure can be opened. The latter form is also suitable for use as a movable weir.

In detail, Fig. 1 shows a vertical section through the head in the Schieiisenaclise. Fig. 2 shows the corresponding top view of one of the two abutments de »Tores. Fig. 3 6 is a view of the front side of the \ "erschlußkörpers and Fig. 4 shows a corresponding dare right section on the line AB. Fig. 5 shows as well as Fig. Ι a vertical section in the direction of the lock axis, and Fig., As well as Fig. In the same way, Fig. 7 shows a vertical section in the lock axis, Fig. 8 shows a plan view and Fig. 9 shows a horizontal section through the closure body along the line EF in Fig. 7.

λίit (7 the movable iron, o reinforced concrete. like. produced gate or W ^T ehrkörper Denoted b by rollers on guide rails c to the Tornischen is guided d and with the protruding on the underwater side paragraph e against an undercut projection / the lock head or Wehrgerinnes is pressed. This arrival \ impact ef is also reflected on the end walls, as shown in Fig. 3 and 4 and Fig. 9 is to be seen in a line continuously having a ί obtuse angle against the moving direction of the weir body forms in order to exclude wedge constraints that could make it difficult to open the passage.

To za make the passage free, the closure body wirl α in the standing with the upper water in permanently open communication pit g sunk, wherein it sits up on individual small pillar Ii, so as not to be influenced by deposited sediments in the altitude.

The buoyancy of the goal body is achieved by installing air chambers; increased so far that it is in the floating limit when the water is reflected. In the embodiment according to FIGS. 1 to 4, only the thin-walled plate k should protrude from the water in this state. When the body is completely immersed, it is.

only to overcome a residual buoyancy force which corresponds to the weight of the water displaced by the plate k. This small force, which at the same time gives the body the ^! If the movement gives the necessary acceleration, it should be exerted in the known manner by the back gear in and: the lifting linkage I. In the lowered state, the closure body; In a well-known way, by locking the pawl on the lay-by! hold, in order to slowly rise again to the final position after its solution.

If the water level drops on the underwater side, it also flows in the room ;; The amount of water resting vertically above the surface of the door also drops. Since the buoyancy generated by the upper water on the base 1 of the closure body remains the same, it now outweighs the weight and i presses the gate body firmly against the stop ef from below. The gate can only be opened again when the water level in the lock is as high as the upper water level.

! While in this embodiment, the require ¹ derliche additional force exerted by the linkage / ι which presses the gate from the boundary floating position down in the second embodiment (Fig. 5 I and 6) compressed air is used, · by the 'line u is inserted into the hollow space ν, which is open at the bottom, in order to lift the gate out of its recessed position. A small amount of compressed air is sufficient to lift the gate, which is in the floating limit position, to the state shown in Fig. 5. "If the lock chamber is now filled, a slight overpressure under the gate body is sufficient to lift it to the actual locking position, because the upper part of the locking body is again designed, as in the case of Fig. 1, so that the underwater load resting on it drains when the body rises above the underwater. If the water level in the chamber continues to rise, the closure body is pressed against the stop / from below, as in Fig. 1. The compressive force that creates the seal corresponds in turn to the lack of water load in the room // ·. This lower gate is opened after the water level has been reflected out by releasing part of the compressed air present in space r.

The embodiment shown in Fig. 7 to 9 differs from that shown in Fig. Ι to 6 essentially in that the load on the gate body is not taken care of from the underwater, but from the upper water. For this purpose, the gate body contains, in addition to the floating chamber i , a cavity o, which is made in a known manner

ζ. B. can be opened or closed by segment gates p and q both j to the upstream as well as to the downstream side.

To lower the gate, open p | and q closed. The upper water penetrates into the room ο and displaces the air in it, which escapes through the line r. Because the weight of the goal body is now

ίο is greater than the buoyancy force, so he sinks into his pit. To prepare the gate for ascent, the contactor /) is closed and the lock s of a pipe or hose line ΐ leading to the underwater level below the lock is opened. Provided that the underwater level is lower than the space ο of the gate body in the sunken position, the water flows off through the line t , whereby air is fed in again at the same time through the line. The gate body can be relieved so far in this way that it is buoyant and is only held in the lower position by the linkage I until the gate can be closed again. After the lock is released, the gate automatically rises to the locked position. If the lock itself is emptied, the rest of the water in space 0 is allowed to flow off to the lock and the buoyancy required for a tight seal is now achieved.

When using this gate on the lower head, an automatic drainage of the water in room 0 to a lower basin will generally not be possible. In this case a connection of the embodiments according to Figs. 5 and 7 is used.

Because this new type of sluice gate or weir is buoyant, it can be replaced quickly and easily in the event of damage. For this purpose, one of the guides c is removed so far with the help of the screw pot w serving as an abutment that the gate can be released from its guide and can swim out of the gate pit.

In order to absorb accidental impacts ship elastic and harmless and in addition, in order automatically to open by accidental impact the gate, both sides of the closure body roof-shaped inclined surfaces can advertising hinged on erschlußkörper \ ~ s

the. The thrust of a ship against them! Inclined surfaces exert a downward partial force at χ , which causes the gate in the floating limit position to sink. Here the foot y of the inclined surface slides into the dashed position (Fig. 1).

Instead of making the point y displaceable, it can also be used in a known manner as the fulcrum of a segment-shaped anchorage, which makes the guide b dispensable.
