(54) TILT CAMERA SHIP LIFT

I

The invention relates to the field of hydraulic structures, in particular to inclined tubeless ship lifters.

A sloping tubeless elevator, including a tray with an inclined section and a ridge, a diaphragm mounted for movement along an inclined section of the tray, as well as a semi-sluice conjugated with an inclined section of the tray and the approaching channel of the upstream (1.

A disadvantage of the known inclined tubeless lift is the large energy and material costs in operation.

The purpose of the invention is to reduce energy and material costs in the operation of an inclined tubeless lift.

This is achieved by the fact that the proposed ship elevator contains a branched pipeline with valves, connecting between an inclined section of the tray and the approach channel of the upstream with a semi-lock, and the bottom of the semi-closed gate is lower than the crest of the inclined section of the tray, while the branched pipeline in its zone of exit to the inclined the section of the tray is provided with a roof matching with the bottom of the inclined section of the tray.

FIG. 1 shows a longitudinal section through an inclined tubeless ship elevator at the approach of a mobile diaphragm with a wedge of water to the headwater (an extensive pipeline is not shown); in fig. 2 longitudinal section through a tubeless elevator after leveling the water levels in the headwater and the horizontal section (the branched pipeline is not shown);

10 in FIG. 3 is a longitudinal section along an inclined tubeless ship elevator with significant navigational fluctuations of the water level in the upstream; in fig. 4 and 5 - successive positions of the mobile diaphragm when leveling the water levels

5 in the wedge and the upper reach.

The inclined tubeless ship elevator comprises a tray containing an inclined section 1, with a crest a, a mobile diaphragm 2, a half-lock 3 in the upper reach and a gate 4 of a half-lock. The semi-lock 3 is interfaced with an inclined section of tray 1 and with the approach channel 5 of the headwater. The bottom b of the half-lock is located lower than. the crest and the sloping portion of the tray 1. The inclined section of the tray is connected to the approach channel 5 of the upper pool with a branched pipe 6, which is blocked by valves 7 and 8. The branched pipe 6 in the zone of its exit to the inclined section 1 of the tray is provided with a cover 9 that is flush with the bottom in the inclined section 1 of the tray. ., The inclined tubeless lift is as follows. The mobile diaphragm 2 moves along the inclined section 1 of the tray a wedge of water from the downstream to the side of the half-access gate 3 (Fig. 1). After the mobile diaphragm 2 approaches the crest and the bottom of the inclined section 1 of the tray, the vessel locks above the bottom 6 of the half-access door 3, and the mobile diaphragm 2 moves towards the downstream until the levels equalize: water in the approaching channel 5 of the upstream and wedge (see Fig. 2), after which the gate 4 of the half-gate 3 opens and the vessel enters the headwater. Posting the vessel from the upper to the lower reaches occurs in reverse order. In the case of significant navigational fluctuations in the water level in the upstream (see Figs. 3, 4 and 5), when the water volume in the wedge is not enough to move the vessel from the upstream to the downstream by moving the mobile diaphragm 2 from the position shown in FIG. . 2, bring to the position shown in FIG. 1, i.e. raising the ship above the ridge of the sloping section, the ship elevator works as follows (see Figs. 3, 4 and 5). When the gate 4 is open, half-gateway 3 will take the vessel from approach channel 5 to half-gateway 3, after which gate 4 of gateway 3 will close. The mobile diaphragm 2 with a wedge of water from the position shown in FIG. 3, moves to the position shown in FIG. 4, when the water level in the half-compartment 3 reaches the ridge of the inclined part i of the tray, then the mobile diaphragm 2 moves to the initial position (see Fig. 5 and 3). The shutter 7 and the lid 9 of the pipeline 6 are opened and the water from the approaching channel 5 of the upstream through the pipeline 6 enters the wedge and rises therein to the calculated level. Then the shutter 7 and the flap 9 are closed, the movable diaphragm 2 is set in motion and led to the ridge and the inclined section 1 of the tray. (This is the position of the movable diaphragm 2 in Fig. 5

4 is shown in dashed lines). The water level above the bottom b of the half-hatch takes a position in which the vessel can pass over the crest of the inclined section 1 of the tray when the mobile diaphragm 2 moves towards the downstream. The mobile diaphragm 2, moving toward the downstream, transfers the vessel to the downstream, and the water level above the bottom of the half-gate 5. is lowered to the crest and the inclined section 1 of the tray. Posting the vessel from the downstream to the upper takes place in reverse order. After the mobile diaphragm 2 is lifted to the uppermost position (in Fig. 5, this position is shown by lines), the vessel is placed above the bottom of the half-gate 3. Then the stop 2 moves in the direction of the downstream until the water level over the bottom of the half-gate 3 does not descend to the ridge of the tray, while the shutter 7 and the lid 9 of the pipeline 6 are closed. The shutter 8 opens, water is drained into the upstream and leveling off in the upstream and above the bottom 6 of the half-gate 3 (see Fig. 3). Then the gates 4 of the half-gate are opened, and the vessel enters the headwater. Claims of the invention Inclined tubeless ship elevator, including a tray with an inclined section and a crest, a diaphragm mounted for movement along an inclined section of the tray, as well as a semi-shutter coupled to an inclined section of the tray and with an upstream reach channel, characterized in that energy and material costs in operation, it contains a branched pipeline with a shutter and an inclined section of the tray interconnecting it and the approach channel of the upper pool with a semi-lock, and the bottom of the bottom for it is lower than the crest. an inclined section of the tray, wherein the branched pipeline in the zone of its exit to the inclined section of the tray is provided with a lid matching with the bottom of the inclined section of the tray.
