Description

Motorized tanker lifeboats are known, equipped with a closure, a water protection system with seawater piping and an air system, which do not provide sufficient security during the passage of the fire zone and high temperatures.

0; a feature of the proposed boat is that the system is water sewn up with polished sprays, created by a fan-shaped thin stream, directed by the node to an angle to the protected surface, which eliminates the reflection (detachment) from it of the jet. Due to the increased effectiveness of water protection, it is ensured that the flap passes through the zone of fire and high temperatures.

To reduce the weight of the boat, its protection system is made with onboard pipelines embedded in the iKopnyc boats as solid longitudinal links that increase the overall strength of the boat.

For reliable isolation of the sides of the boat, they are double-walled, forming at the same time airborne insulation of the sides and air buoyancy boxes. The closing of the boat for the case protection of its upper horizontal surfaces is made in the form of hinged metal covers, between which there is a pipeline with dispensers of the water protection system.

FIG. 1 schematically shows a boat in cross section; in fig. 2 - scheme

water protection of the boat.

The boat is made of light alloy. The double walls of the sides, forming the air boxes 1, provide insulation of the internal space of the boat.

Engine 2 operates on a propeller and, through a PTO, drives pump 3 of the water protection system.

The water protection system includes onboard pipelines 4, built into the hull of the boat as longitudinal root connections, providing, together with other hull structures, its overall strength, and the upper trench pipeline 5. The pipes 4 and 5 are provided with sprays 6. In FIG. 2 shows the location of the spray jet. At an angle of 25-30 ° to the board. However, the specific value of the angle is open: the nozzles are determined based on the above condition.

The closing of the boat is made in the form of hinged covers 7, between which the pipeline 5 of the upper river is located. To provide passengers who are in a locked boat with air, as well as to operate with compressed air. From the cylinders, the air through perforated pipes (not shown in the drawing) enters the boat.

If it is necessary to pass through a fire zone on a boat, for example, through Plum, which engulfed the surface of the water around the tanker in an accident and a spoon, the boat with the crew is lowered onto the water with the air caps on it and the air system turned on. At the same time, the engine is turned on and the water protection system is activated.

Subject invention

1. A motor tanker rescue sluice, equipped with a closure, is water protected with seawater pipelines and an air system, characterized in that, in order to safely pass through the fire zone and high temperatures by increasing water protection, the water protection system made with silky sprays, created by them fan-shaped

a thin jet directed at such an angle to the protectable surface, which ori excludes reflection (detachment) of the jet from the surface.

5 2. A boat of claim 1, characterized in that in order to reduce its weight, the water protection system is made with onboard pipelines embedded in the hull as hull structures that are part of the longitudinal links that ensure the overall strength of the boat .

3. Boat on ip. 1 and 2, characterized in that, in order to ensure reliable insulation of its sides, it is made with double-walled boards, which form at the same time air insulation and air chiki-buoyancy.

4. Boat on PP. 1, 2 and 3, characterized in that, in order to securely secure its upper horizontal surfaces, the closure

The lifeboat is made in the form of hinged metal covers, between which there is a pipeline with sprayers of the water protection system.
