Abstract

FIELD: shipbuilding.

SUBSTANCE: invention relates to shipbuilding, namely, to underwater facilities rescue equipment. Rescue submarine object rescue vessel comprises a strong housing which is made in the form of a truncated cone or a cylinder, covered with ends by bottoms in the form of spherical segments with input hatches. Inside the housing there are places for rescued and independent means of life support. In its upper part there is a fairing, and in the lower part – a device for attaching the camera to the underwater object. Body of the rescue pop-up chamber is composed of two parts: the upper part is light and the bottom part of the body is heavy. Inflatable buoyancy unit is installed in niche of flap upper part closed by movable flaps.

EFFECT: improved navigational properties of the surfacing rescue chamber.

Description

The invention relates to the field of shipbuilding, in particular to the rescue equipment of underwater objects.

A known rescue pop-up submarine (PL) camera, including a truncated cone hull with upper and lower access hatches, a device for securing it to the submarine hull, life support equipment, pushers and technological eyes for lifting and installing on the submarine hull in factory conditions [1] .

The disadvantages of this rescue pop-up camera are low seaworthiness: low buoyancy, low freeboard height, significant angular and axial vibrations of the camera on sea waves. The small buoyancy margin of the rescue pop-up camera can lead to the camera not getting to the surface in an emergency with a slight overload. The low freeboard height makes it impossible for submariners to exit the SWR during sea waves of more than 1 point because of the danger of flooding the camera through the open top hatch. Significant angular and axial vibrations of the camera during sea waves lead to a decrease in the time that a person can stay in the rescue pop-up camera.

A known rescue pop-up camera of a submarine [2], adopted as a prototype, the top hatch of which is equipped with an inflatable fence with air supply and filling valves, controlled both outside and inside the hull. An inflatable fence provides the evacuation of people from the rescue chamber and its towing in conditions of sea excitement.

In this chamber, due to the presence of an inflatable fence, the likelihood of flooding of the chamber when opening the top hatch on a wave is significantly reduced. Other above-mentioned disadvantages of existing SWR in this technical solution are not eliminated.

The disadvantage of this option rescue pop-up camera is also the lack of protection of the inflatable fence from damage.

The objective of the invention is to improve the seaworthiness of the SWR: an increase in the margin of buoyancy, stability and height of the freeboard of the SWR, a decrease in the angular and axial vibrations of the chamber on sea waves.

The tasks are solved in that the known rescue pop-up camera of an underwater object containing a durable body made in the form of a truncated cone or cylinder, closed at the ends with bottoms in the form of spherical segments with access hatches, inside the body there are places for the rescued and autonomous life support equipment, in its upper a fairing is fixed to the part, and a camera to the underwater object is attached to the bottom, the rescue pop-up camera body is made up of two parts: the upper part is light and the bottoms The second part of the hull is heavy, an inflatable buoyancy unit closed by movable wings is installed in the niche of the upper fairing.

New distinctive features of the inventive rescue pop-up camera are the composite structure of its body, the buoyancy unit with movable protective flaps located in the upper part of the camera.

The use of the upper light part in the housing design will increase the buoyancy margin of the chamber. Heavy - the lower part of the chamber will increase its stability. The inflatable buoyancy unit will increase the freeboard height, camera stability and significantly reduce the angular and axial movements of the camera on sea waves. Closing the inflatable buoyancy unit with movable wings will protect it from damage.

In FIG. 1 shows a rescue pop-up camera with a composite body, a buoyancy unit in the folded position with closed movable wings.

In FIG. 2 shows a rescue pop-up camera with a composite body, an inflated buoyancy unit and open movable wings.

The rescue pop-up camera (Fig. 1, Fig. 2) consists of the upper (light) part of the housing 1, reinforced by ring frames (stiffeners) 2, fairing 3, hatch 4, lower (heavy) part of the housing 5 with hatch 6, inflatable unit buoyancy 7, closed by movable wings 8.

The technical and economic advantage of the proposed design of the rescue pop-up camera compared to the known rescue pop-up camera according to the patent No. 2479463, adopted as a prototype, is to increase the likelihood of rescuing people during an accident of an underwater object with laying on the ground by improving the seaworthiness of the rescue pop-up camera, increasing buoyancy , freeboard height, stability and reduction of angular and longitudinal vibrations on sea waves.

A mathematical model of the stress-strain state of the rescue pop-up camera of the proposed design is developed. Estimated calculations of its weight and size characteristics are made.
