Description

The invention relates to shipbuilding, in particular to devices. For protecting the underwater part of the hull from fouling, as well as for protecting the entire hull of an underwater object.

A device is known for protecting the underwater part of the ship’s hull from fouling, containing a source of a gaseous protective substance, mainly a mixture of air and ozone, communicated through pipelines, distribution and pressure regulating valves with holes made in the plating sections of the underwater part of the ship’s hull [g}.

A disadvantage of the known device is its low efficiency of protecting the underwater part of the hull from fouling.

The purpose of the invention is to increase the efficiency of protection of the underwater part of the hull from fouling.

The goal is achieved in that in a device for protecting the underwater part of the ship’s hull from fouling, containing a source of a gaseous protective substance, mainly a mixture of air and ozone, communicated through pipelines, distribution and * shut-off and control valves with holes made in the plating sections of the underwater part of the hull the vessel, on the latter there are installed power elements on which additional sheathing is made of macroporous material subjected to hydrophobic treatment, forming with power elements cops and the said upholstery of the hull of the vessel hermetically separated from one another intershell compartments.

In FIG. 1 schematically shows the proposed device for protecting the underwater part of the hull from fouling; in FIG. 2 - cross-section compartment, cross section.

The device comprises a source 1 of a gaseous protective substance located inside the ship’s hull, mainly a mixture of air with ozone, a compressor 2 for supplying a protective substance to the pipeline 3, on which. installed distribution and shut-off and control valves 4.

- '. Holes 7 are made in sections of the casing 5 of the underwater part of the ship’s hull 6 and power elements 8 are installed on which additional casing 9 of the macroporous material subjected to hydrophobic treatment is mounted. Sheaths 5 and 9 and power elements 8 form hermetically-delimited inter-compartment compartments 10. The hydrophobic 20 treatment of the macroporous material prevents water from entering the compartments 10 through the pores of the material.

The device operates as follows.

ι. Compressor 2 delivers under pressure • a protective gaseous substance from source 1 through pipeline 3 with valves 4 to the casing compartment 10 40 of the ship’s hull b. The substance, passing under pressure through the pores of the macroporous cladding material 9 over the entire area of the compartment 10, comes out with some excess pressure normal to the surface of the cladding 9, exerts strong mechanical stress on the fouling and creates a dense uniform protective layer over the entire treated surface of the cladding 9. The invention makes it possible to reduce material and labor costs for cleaning ship hull from fouling.
