(54) DEVICE FOR LIFTING A FLAILED FLOATING

This invention relates to emergency spans and equipment.

Devices are known for lifting sunken craft, consisting of two interacting complexes — a mixing one, designed to prepare a transportable mixture consisting of floating bodies with water, and an injection complex delivering the prepared slurry to the object to be lifted.

The purpose of the invention is to simplify the device.

This is achieved by the fact that at the far end of the supply line, for example, a jet pump (ejector) is mounted directly on the hull of the object being lifted and connected to the hydraulic system of the rescue vessel.

FIG. 1 shows schematically the line for supplying floating bodies from the surface to the body of the object being lifted; FIG. 2, a device for lifting sunken vessels, side view; on - section of the ejector; in fig. 4 shows a section along A-A in FIG. 2,

MEDIA

A device for lifting sunken vessels is placed on the rescue vessel 1 and consists of a mixing complex 2 and an injection complex interacting with it. The latter, which is a supply line, contains supply hoses 3, an ejector 4 and a high-pressure water supply unit, in the form of a pump 5 connected to an ejector by a pressure hose 6, the supply line is lowered from the side of the rescue vessel with the help of an arrow 7 and is supported by a cable 8.

The discharge side of the supply line

with the object to be lifted 9, the Mixing Complex serves to prepare a transportable mixture of floating bodies 10 with water supplied to the mixer by a feed pump 11 through the nozzle 12 and

has a tank 13, the level of water in which is maintained (regardless of its flow rate) constant, due to drain 14 or any known automatic valve, regulator inlet and KOY level 15 to two communicating compartments, one of which is mixing. In the bearings 16 and 17 of the latter, mounted on the wall of the tank and neperopopc, a mixing drum 18 is horizontally placed, immersed in water and partially protruding above its surface, on which is a layer of floating bodies delivered from the storage location by an air ejector (not shown) as far as consumption. The mixing drum consists of spiral surfaces i9i of end walls 20 and axles 21, 22. On axis 21 a pulley 23 is attached, connected by a belt 24 to a gearbox 25 driven by an electric motor 26. Axle 22 is hollow and communicates the mixing drum with a suction part of an injection unit The complex, air pump (ejector) after the bottom has a housing 27 and a nozzle 28. At the same time, the ejector is always placed under water, or at the far end of the supply hose (Fig 1) and installed directly on the raised object in the place where it is necessary under Avoid floating bodies. If the ejector is located in the middle part of the main pipe (this variant is not shown in the drawings), then its pressure head is connected to the pressure hose lifted by the object. After the introduction of the pressure part of the device for lifting sunken vessels into the object being lifted and filling the tank 13 and the entire supply line with water supplied by the feed pump 11, the floating bodies 10 are fed into the mixing compartment, placed on the surface of the water in a uniform layer completely covering the part of the mixing drum protruding above the water 18. The latter is driven into rotation from the electric motor 26 through the gearbox 25 and, when moving, passes through a layer of floating bodies, captures them with spiral surfaces 19 and Comes to its center line while mixing with water. The air trapped between the floating bodies and trapped with them by the drum from the surface is displaced by water through the holes present in the spirals. The floating bodies delivered to the center of the drum, which form a transportable mixture with water, enter through the hollow axis 22 into the suction part of the injection complex, having a certain amount of pressure from the mixing drum. The water-jet pump of the injection complex, driven by high-pressure working water supplied through the pressure hose 6 of the ship’s high-pressure installation 5, creates a reduced pressure area, draws the prepared mixture, and, passing it through itself, pumps it into the object to be lifted. The invention of the Device for lifting sunken floating equipment, consisting of two interacting complexes - a mixing one, designed to prepare a transportable mixture consisting of floating bodies with water, and a pressurized container delivering the prepared slurry to the object being lifted, characterized in that simplifying the device at the far end of the supply line, for example, a jet pump (ejector) is mounted directly on the body of the object being lifted; this is connected to the rescue hydraulic system on. 1211 U 1 23 fPuB.3 Vazm 22
