Description

The present invention relates to well-known ship-walkers, in which, in order to avoid complicated mechanisms when raising and lowering vessels from one bay to another, closed trays are used, equipped with tanks and float chambers.

In FIG. 1 shows a vertical longitudinal section of the proposed ship harbor; FIG. 2 is a transverse vertical section of the movable part of the ship-harbor; and FIG. 3 is the same fixed part.

The proposed shipwreck sinks and moves in the upstream of the river in such a way that its weight in case of rest is equal to the weight of the water it displaces. Vessel Co enters tray ABCD (Figures 2 and 1) through gate D of the shipwalker while it is in the upper position. Thereafter, the DI gate closes and the tray ABCD is hermetically closed; then the ship-collector, together with the vessel enclosed in it, is lowered down until the horizons of the chamber and the lower pool are not matched; opening the gates of the chamber Da and the dam D - they release the vessel to the downstream. The lifting of the vessel is similar.

The movable part of the ship restraint (Fig. 2) consists of three parts: 1) a tray ABCD with a constant water level in it, 2) a tank K filled with water through holes not shown in the drawing or emptyed by pumping water at the top position of the tray with a siphon F, approved at the dam PQ, 3) of the chambers b, b, filled either with water (in the upper position of the ship restraint), or with air (in the lower position). Along the outer contour of chamber K around the entire movable part there is a projection e, e, the purpose of which is to lean on the walls 5 of the receiving chamber of the fixed part of the ship-collecting platform. The purpose of this camera is to isolate the ABCD tray in the lower position from the water pressure when opening the doors D and Dg. The other fixed part of the device is the receiving chamber e, e (Fig. 1 and 3),

located on the flybet and formed by the three walls S; the fourth wall is the dam itself. The dimensions of this chamber correspond to the dimensions of the box / C, and when flooded, the latter enters chamber e, e and rests its bottom on the bottom of its fd, and its projections ee on the walls 5.

The mobility mechanism of the ship hob is as follows.

In the case of a dead position of the mobile part of the ship restraint, the tank K is filled with water (weight of the tray ABCD const), chamber b, -air. The mobile part of the shipwright is afloat, however, the horizon of the upper reach is higher than the horizon of water in the tray by a certain amount h (Fig. 2). The ship elevator rises above the headwater horizon by the size of the AO (Fig. 2). If cells (f), b are filled with water (by opening air vent valves not shown in the drawing), the ship restraint will sink and its downward movements will continue until its movable part enters the fixed part (like a piston in a cylinder), the speed of travel will be gradually reduced (by means of a pipe which communicates the bottom of the fixed part of the ship-landing vessel with the headwater, not shown in the drawing, it would be possible to regulate the speed of water flowing out through this pipe, and therefore the speed of lowering of the moving part ) until the rectangular projections e, e, with flexible insulation, attached knim, are not supported on the edges of the receiving chamber, e, e.

When the ship restraint stops in the lower position, open the holes in gates D and D, and when the levels are equal, open the gate and release the ship into the lower reach. If the ship lifter needs to be lifted up, then airborne b, b is injected into the chambers, and the ship will be lifted by the ship restraint.

In order to avoid the device pumping station for air supply

into the chambers b, b, it is proposed to let in air from hermetically sealed chambers (galleries) d, d (fig. 3) arranged in the fixed part of the ship receiver (ship receiver) and projected onto the horizontal plane under the cameras b, b (fig. 2) of the ship receiver. These d, d galleries have q, q holes in the upper walls for air release. The air will come out in the form of bubbles and fill the chambers b, b, displace water from them, and galleries d and d will be filled with the upstream water flowing into them. Galleries are located above the downstream; therefore, when the holes q, q are closed and the d and d galleries are connected with the downstream air through the /, / holes (Fig. 3) having the downstream reach, water will flow out by gravity and the galleries will be filled with air.

As a consequence, the shipwright will begin to rise and reach the dead position; then the siphon F is actuated, the harbor lifter becomes lighter, rises to the height of the "upper position"; the horizons of the chamber and the upper pool are matched, and the vessel can be let in or out through gate D. To fill the reservoir K with water (if they wish to lower the bottom of the tank To the hole, not shown in the drawing) and the harbor will approach the dead position. Having also opened the air outlets of the chambers b, b, they receive the forward movement of the ship restraint downwards. You can make guides for the right move.

The subject of the patent.
