RU2261819C2 - Rescue ship's lift - Google Patents

Abstract

FIELD: raising sunken vessels, mainly sunken submarines.

SUBSTANCE: proposed rescue ship's lift is made in form of submarine provided with grips and passageways for crew. Smoothly located along sides of this submarine are frames with brackets to which bearing levers and hydraulic cylinders are connected. Grips have beams and tubular sides made from horizontal pipes located vertically in these beams; they are also provided with brackets for connecting the said levers and hydraulic cylinders for vertical motion of these grips and closing of their bent lower ends under sunken vessel, thus forming bilge for this vessel. Horizontal pipes are communicated by means of end tubular strips; they are also communicated with compressed air reservoirs through compressors for transfer of air from reservoir and vice versa for forcing water out of said pipes and admitting water to them. Each passageway is made in form of pipe running through pressurized aperture in submarine hull bottom and provided with elements for hermetic connection with escape hatch of vessel to be hoisted.

EFFECT: reduction of ship-raising time; enhanced safety.

Description

Name: Lifeboat lifesaver

Applicability: Navy, marine, lake and river fleets, marine archeology and emergencies, cleaning of marine areas, the rise of nuclear submarines.

Known underwater vehicle SU 1394622 from 03/07/01 for lifting ships with approach along the axis and capture by hydraulic turns in the ground of the bearing arms of the claw under the sunken ship. The task is intractable.

It is known that a US rescue ship 1814689 dated 07/14/31 rescues a team using a vertically movable power buoy / bell / with upper and lower docking hatches to the vessels for entering and leaving the rescued in the pressure chamber of the rescue vessel, while the vessels are located one above the other, superimposed by chain and cable guides of the buoy, by divers, to regulate the distance of the buoy's travel along the sensor and ensure landing on the hatch.

According to the patent, the team is saved, but the vessel remains at the bottom.

Known underwater rescue USA 1814642 from 07/14/31, identical to the aforementioned USA 1814689 from 07/14/1931 in the process of rescuing the crew using a bell, and differs in the use of anchor mechanisms with chains passed through the hull with the anchor hitch to the sunken ship to maintain distance rescued vertical stroke of the bell along the guide ropes, with a controlled process by the sensor floating immersed in water in the capacity of the lifeguard case.

Such a technical solution saves the crew and has the ability to provide technical assistance to the sunken ship for repair, but the ship cannot be lifted without giving the latter sufficient buoyancy and lift to a large tonnage sunken ship with landing on silted bottom soil.

A deep-water rescue ship SU 1796544 dated 09/10/1990 is known for lifting a sunken ship by loading onto deck slips by pulling cargo winches and crawling a rescue ship under the sunken ship by an additional process of soil erosion by thrusters with a directed stream.

Such a solution cannot be used for lifting a large vessel in sea and river conditions, because as the soil erosion under the vessel, the latter sinks to the bottom with simultaneous siltation of the lifeguard.

A submarine is known for lifting sunken objects SU 1807958 dated 03/05/1990, a catamaran type vessel from two side pipes of a detachable buoyancy connecting pipe with replaceable pipes interconnected by an arch beam, on top of which a spherical control cabin is connected, and a hydraulic hydraulic gripper is suspended from the bottom of the beam made as a scrap for loading scrap metal into wagons by overhead cranes, and buoyancy of side pipes when lifting the vessel is created by a hydroreagent filler, with the filing of their depressurization capacity th pyrotechnic devices, machines.

Such a technical solution does not save the crew of the sunken ship and cannot be used to lift large vessels in the bearing capacity of lifting gripping devices, while there is a drawback in the use of a chemical reagent with possible consequences, as well as insufficient design reliability for operation in marine conditions.

Known technical solutions do not provide guaranteed conditions for rescue operations in the presence of a large landing side roll at the sunken ship. In addition, US patent technology cannot do without the participation of divers to couple vessels for rescue operations. This limits the possibilities of work in the deep conditions of the seas and oceans. Subsequent SU patents are structurally complex and technologically challenging to use and justify the return on investment.

According to the invention, the crew and vessel rescue technology includes landing a boat elevator over a sunken vessel with open beam tubular sides of the grips, forming a passage between the bent lower ends, covering the vessel from above or coaxially approaching from the bow or stern, grabbing the vessel in the hold with a raking vibrating passage in the ground, bent the lower ends of the grips, their closure at the center line is completed by closing the hold under the vessel, then the adapters with electromagnetic sealing heads on the cylinder are lowered by hydraulic cylinders ke and the team is saved, and then the ship is lifted by supplying air to the side pipes of the grips. The technology provides the lifting of vessels up to twenty or more thousand tons.

According to the invention, the lifesaver-rescuer, mainly submarines, is made in the form of a submarine containing grips, adapters for the team with the upper hatch and the lower elements of the hermetic connection with the hatch of the sunken ship and the submarine, along the sides of the latter are made, with a departure from the bow and stern, evenly placed side frames with add-ons and compressed air tanks located inside them, as well as vertically mounted side brackets to which supporting bearing arms are connected and idro cylinders, while the grips are made with girder and tubular sides of horizontal ship-lifting pipes located vertically in these beams, and also have brackets by means of which they are connected to the said levers and hydraulic cylinders with the possibility of vertical movement of these grippers and closing their bent lower ends under a sunken vessel with the formation of a hold for the latter, moreover, these horizontal pipes are interconnected by end pipe bridges, and also communicated with the mentioned reservoir compressed air through compressors that can pump air from the tank and back to displace and let water into these pipes through nipples with grids located on the lower pipes, while the grippers have hydraulic cylinders at their sides with heads to support the vessel being lifted in the hold, and the adapter for the team is made in the form of a pipe passed through a hole sealed by the upper gland in a ball installed in the opening of the bottom of the hull of the submarine, sealed by the upper and lower flanged with seals, while the pipe is suspended on the hydraulic cylinders of its movement and equipped with a ladder located inside it, a head with electromagnets located at the lower end, as well as an upper receiving platform with a folding guard and a rope ladder.

The bent lower ends of the grips are made between the latter with hardened arched formations with niches in which vibromechanisms are installed for the passage of bottom soil.

Niches of vibromechanisms are made with hatches for their tight closing.

The grips are also made with openings for the passage of bottom soil located between these hatches and lower horizontal pipes.

Such a technical solution of the invention of the rescue hoist, the use of a submarine with additional equipment of the latter, greatly simplifies and speeds up the preparation of design work, as well as the manufacture and commissioning of the fleets for practical use in marine and oceanic conditions.
