Description

The invention relates to ship repair and can be used during repair of underwater ship hulls and watercraft afloat.

A device for sealing holes in the hull of the craft, including composite tubular elements connected to the unit cold installation, and connecting hoses 1.

A disadvantage of the known device is that the tubular refrigeration system along the entire contour of the frost-free space requires a large consumption of pipes and refrigerant, as well as a large investment of time for mounting and freezing the frost-free space, especially in summertime. When dismantling the tubular refrigeration system, it is necessary to specifically melt the ice into which the cooler elements of the tubular system are frozen.

The purpose of the invention is to increase the efficiency of production of repair work in the underwater part of ship hulls and floating craft by reducing the labor intensity and time of frost-free work.

This goal is achieved by the fact that the device for sealing a hole in the body of the floating device, including its composite tubular elements connected to the refrigeration unit and connecting hoses, is made in the form of a three-wall barrier with a plug-in rigid frame and an inflatable chamber in the upper part of the walls fences and associated with the hull of the vessel with flexible tubular cooler elements with electromagnetic suction cups.

FIG. 1 shows the volumetric layout of the device in the area of the seal of the hole in the moving part of the hull; in fig. 2 - device diagram, section; in fig. 3 - structure of the cooler element; general view; in fig. 4 - a section of the cooling element with a flexible joint and an electromagnet; in fig. 5 - plug-in collapsible frame.

The device 1 is installed in the underwater part of the ship's hull 2, on the deck of which the unit 3 of the refrigeration unit is located, connected by connecting hoses 4 to flexible tubular cooler elements 5 equipped with electromagnetic suckers 6 and includes a three-wall fence 7 with an inflatable chamber 8 and with a plug-in collapsible frame 9.

The use of the device is as follows.

To the damaged part of the ship's hull, for example, to the underwater hole in the boring area of the vessel 2, from the unit 3 of the refrigeration unit using connecting hoses 4, the contour of the tubular cooler elements 5 with electromagnetic suction cups 6 is applied so that the hole is in the middle contour. Thereafter, electromagnetic suckers 6 are included which are attracted

to the steel shell of the enclosure and hold in place the cooler elements 5, to which the three-wall fence 7 is tightly attached with the inflatable chamber 8. Next, air or water is supplied into the cavity of the inflatable chamber 8 of the enclosure 7 so that it takes the shape of the intended frost-free space and inserted lightweight collapsible rigid frame 9 is fed into it. Then coolant is pumped and pumped into the tubular system of the elements of the coolers 5

unit 3 until the edges of the walls of the thermal fencing 7 are tightly and tightly frozen onto the side of the pontoon along with the cooler elements 5. The remaining water and the ice formed from the tank

The created frost-free space is removed overboard and proceeds with repair work to seal the hole.

During the entire period, the iodine works on sealing the holes in the freezer system are in operation. In winter, the installation of the proposed device is carried out in the lane, cut at the side of the vessel.

When the device is dismantled for rotary use, the freezer system is turned off, after the ice is thawed out by the action of heat from the surrounding water, the connecting hoses 4 are removed, the frame 9 is removed from the three wall panel 7, which then rises to the deck. In winter, the dismantling of the proposed device is carried out as follows.

From the freezing system and the tubular cooler elements 5, the refrigerant is removed, and instead, heated water, air or steam is passed through the system. At the same time, the inflatable chamber 8 of the fence 7 is heated in the same way. After

the complete thawing device is removed from the lane to the deck. Nylon rubberized fabrics can serve as a material for making a three-wall fence 7 with an inflatable chamber 8.

The proposed device makes it possible to increase the efficiency of repair work in the underwater part of ship hulls and floating craft by reducing the labor intensity and time of freezing works.
