Description

Closure body for water containers, in particular for locks The invention relates to a closure body for water containers, in particular for locks, which can be lowered into a niche in the sole, and consists of the special 'design of this Closure body.

According to the invention, a hollow one is too segment-like after the underwater curved bluff body in the stowage position below the center by tilting bearings against two jam approaches of the lock walls supported. Above, in the middle and below the bluff body is provided with bearing rollers on each side through which it is lowered when it is lowered on each of the two lock walls by two offset from one another, after obren curved runways is guided in such a way that it is after initial Tipping lifts from its tipping bearings, with the middle rollers on the upper edge, place the lower rollers on the lower edge of the taxiway facing the upper water, while the damming body with the .upper rollers in every position on the underwater side Runway is guided.

The drawing shows a lock gate according to the invention as an exemplary embodiment.

In front of the closure body a there is a trough-shaped surface on the upper water side Niche arranged in the bottom of the lock, in such a way that the segment surface of the damming body finds its constant continuation in the trough-shaped sole surface. This trough is so large that it completely accommodates the lowered closure body.

When the closure body is tilted, a short flow slot is created under it free, that of approximately concurrent, curved surfaces (closure body and Sole niche) is limited. Because these boundary walls are above water in the bottom surface of the niche, on the underwater side in the curved wall surface dies Damming body leak, the outflowing water is guiding and ascending direction given and a relatively calm, vibration-free filling or emptying reached the lock.

In the exemplary embodiment, the driving force is provided by a winch k made by articulated chain transmission and the toggle-like guide rod i fed your gearbox of the bluff body, the one with the gear rims Rollers b on the taxiways equipped with a rack or a headstock e is running.

In the rest position, the bluff body is secured by special bolts (not shown). In order to limit the driving force, the forces can be balanced in this way be that their mean force goes approximately through the tilt bearing g and the buoyancy is equal to the dead weight of the bluff body. If when emptying the lock the If the mean force moves downwards, the compensation is possible by means of knee levers on both sides and easily accessible with a counterweight.

If such a gate is to be used as an upper gate, it will be useful so deep that in the stowed position at the lowest underwater there is at least 0.5 until i, o m is immersed.

The seal of the gate in the stowed position can be made laterally in a known manner can be achieved by means of spring plates and wooden strips below.

All drive parts, with the exception of the rollers, can be coated.

A particular advantage is that when using the new gates resulting simple training of the lock heads.
