Description

The invention relates to shipbuilding, to water rescue equipment [B63C7/00, B63C9/00, B63B35/00, B63B43/00, B63B45/00].

The prior art known Self-rescue or rescue device of the ship in distress and method [CN105035280 A, publ. 11.11.2015], which discloses the device and method of self-rescue or ship rescue in distress. The self-rescue or rescue device of a ship in distress comprises a movable supporting and wrapping layer of the ship's hull, a guide cable, a first receiving and unloading device and a second receiving and unloading device, the first receiving and unloading device being a lifting and unloading device and the second receiving and unloading device fixed on two sides of the ship's hull deck. Sets of fixing ropes are located at two ends of the movable supporting and wrapping layer of the ship's hull, respectively. The movable supporting and wrapping layer of the ship's hull is attached to the first receiving and unloading device through one fixing cable and is received at the first receiving and unloading device. The ship's self-rescue or distress rescue device is of simple structure, flexible and convenient to operate, and is capable of performing self-rescue and ship rescue quickly and efficiently. Specifically, the impact resistance of a ship hull can be improved, real-time plugging can be performed, or real-time batch plugging can be performed, and therefore seawater intrusion or crude oil leakage is prevented. If necessary, powerful balanced buoyancy support can be quickly provided, and a ship in distress or distress can effectively self-rescue or salvage. The disadvantages of this technical solution are technically complex implementation on a small ship, the need for high energy costs to run the device, which is impossible on a small ship.

Also known from the prior art Water pleasure boat, easy to launch [CN211391614 U, publ. 09/01/2020], which reveals a water pleasure boat that is convenient for launching. The hull of the ship, on the upper end of the internal cavity of the hull there is a partition. Stand columns are installed at the lower end of the partition in a spaced mode. Through holes are made in the front and rear parts of the ship's hull, respectively, hydraulic columns are installed in the four corners of the lower end of the partition, and a concave box is installed at the lower end of the internal cavity of the hull. The power structure is located in the ship hull on the right side of the upper end of the ship hull, the pipeline is installed on the left side of the power structure, and the air cushion is installed on the outside of the air outlet. The utility model discloses an easy-to-launch water pleasure boat. Extending through the hydraulic column, opening the door panel, the airbag conveniently extends from the body; the air can be compressed by the operation of the air pump, the air is released into the internal cavity of the air cushion through the pipeline, the air cushion expands, leaves the ship's hull, increases the buoyancy of the ship's hull, prevents sinking, and is not prone to submerge in water in an accident, the difficulty of rescue is reduced, the situation where a good rescue opportunity is missed is eliminated and the risk to life safety is greatly reduced. The disadvantages of this technical solution are the large size of the main element that maintains buoyancy, namely, the air cushion, as well as the low stability of the flat-bottomed vessel, which adversely affects buoyancy. These shortcomings greatly limit the capabilities of the vessel.

The closest in technical essence is the Rescue device on ships [EP0111224 A2, publ. 06/20/1984], which discusses a life-saving device to reduce the risk of sinking ships or similar floating bodies. A reduction in the risk of ship flooding, as well as a significant increase in the likelihood of survival of people on ships, can be achieved by using a device for inflating containers with displacement spaces that can be filled with air or other gaseous media and, thus, they can be increased in volume if there is a loss of buoyancy on the ship, or the like. vessels are designed in such a way that they can compensate for the loss of buoyancy in the vessel.

The main technical problems of the prototype is that the gaseous media with which it is proposed to fill the tanks require a sealed below-deck space, which is absent in many types of small vessels, such as boats and boats. Additionally, the use of gaseous media to shift spaces, while the ship's crew and cargo are in the hold, can lead to failure of the inflation containers, which will lead to an instant loss of the ship's buoyancy and its flooding.

The objective of the invention is to eliminate the disadvantages of the prototype.

The technical result of the invention is the creation of a device that makes it possible to exclude the sinking of small boats, the death of people and the flooding of a floating facility without significantly limiting the free volumes of the vessel.

The claimed technical result is achieved due to the fact that the device for ensuring the buoyancy of small boats, characterized by the presence inside the hull of a small boat of containers for inflation with gaseous media, providing lift in case of emergency flooding, characterized in that it contains emergency life-saving appliances mounted symmetrically along the keel on both sides vessel, wherein each of the emergency life-saving appliances is made in the form of an elastic inflatable shell containing a gas medium supply valve into the shell, connected to a gas cylinder containing a gaseous medium under pressure, or a squib, with the possibility of providing lifting force when the shell is filled, a gas discharge valve environment, for folding the shell, the shell is fixed to at least one of the elements of the ship's hull.

In particular, emergency rescue equipment is controlled from the control unit.

In particular, the shape of each of the elastic inflatable shells corresponds to the shape of the interior of the ship's hull in which it is mounted.

In particular, from the control unit, when starting emergency rescue equipment, emergency light, sound and radio devices are simultaneously launched.

The buoyancy device for small boats is designed to save people on the ship in an emergency and is implemented by emergency rescue equipment 10 placed along the keel 4 inside the hull 1 of the small boat, under its deck 2 or on the bottom 3 inside the ship.

The emergency rescue equipment contains an elastic inflatable shell 5, which is connected through a valve for supplying a gaseous medium to the shell 6 with a gas cylinder 7 containing a gaseous medium under pressure, with the possibility of providing lifting force when the shell is filled. On the elastic inflatable shell 8, a valve for discharging the gaseous medium from an elastic inflatable shell 8 and fastening elements 9 to the ship's hull are mounted.

The shape of each of the elastic inflatable shells 5 correspond to the shape of the inner part of the vessel hull 1 in which it is mounted.

The buoyancy device for small boats is used as follows.

To ensure buoyancy in the event of emergencies associated with flooding of the internal volumes of the vessel, emergency rescue equipment 10 is installed on a small vessel inside the hull 1, under deck 2, on the bottom 3 or keel 4, at the command from the control unit (not shown in Fig.) the elastic inflatable shell 5 of the emergency rescue vehicle 10 is inflated with a gaseous medium that provides the creation of a lifting force. Also, on command from the control unit, emergency light, sound and radio devices are launched (not shown in Fig.). The supply of the gaseous medium to the elastic inflatable shell 5 is ensured by actuation of the valve for supplying the gaseous medium to the shell 6 from the gas cylinder 7 attached to it, in which the gaseous medium is under pressure. The gas cylinder can be replaced with a squib to fill the shell. When eliminating an emergency or to adjust the achieved buoyancy, the gaseous medium from the elastic inflatable shell 5 is discharged through the gaseous discharge valve from the elastic inflatable shell 8. With the help of fastening elements 9, emergency life-saving appliances are attached to the hull of the vessel 1. The fastening elements can be made in the form of carabiners , lanyards, rings, flexible elements, etc., providing installation / dismantling of emergency life-saving appliances 10.

The technical result - the creation of a device that makes it possible to exclude the sinking of small-sized floating craft, is achieved by providing a lifting force that is formed when an elastic inflatable shell 5 is filled with a gas medium, with the possibility of providing a lifting force when filling the shell coming from a gas cylinder 7 attached to it, in which the gaseous medium is kept under pressure when the valve for supplying the gaseous medium into the shell 6 is actuated, while the fastening of the emergency life-saving appliance 9 to the body ensures its vertical movement.

The proposed utility model allows:

• limit the flow of water into the hull of a small boat;

• to create an additional lifting force, excluding the ship's flooding;

• ensure that the distressed ship is kept afloat until help arrives;

• carry out the rescue of the crew and valuable cargo, if any, on board.
