Description

"one

This invention relates to shipbuilding, in particular to the construction of dry docks.

The purpose of the invention is to more effectively use the working area of the dock.

FIG. shows a dock without removable partitions, a plan view; figure 2 - the same, with one longitudinal partition; on fig.Z - shutter with the absence of a longitudinal removable septum in the head of the dock, the section; in FIG. 4, the same, in the presence of a longitudinal removable partition in the head of the dock; on phi: g, 5- node 1 in figure 1; 6, vertical section.

The dry dock consists of chambers 1 and 2, of a longitudinal detachable partition 3, compartments of the dock 4-7J of the main shutter sections of folding type with struts 8 and 9 and transverse intermediate closures 10 and II. In the dock there are vessels 12 and 13 prepared for descent , and vessel 14, being constructed or reconstructed.

Sections of the main gate 8 and 9 include a metal structure I5 with stops 16 for removable struts 7 with ballast compartments 18 and 19 and hinges 20 located in them.

Seal sections of the shutter 8 and 9 are made in the form of a bar 21 along the contour of the bearing section and inflatable seal 22 installed vertically between the sections of the shutter.

In the bottom of the dock there is a niche 23 for removable struts 17 and a niche 24 for the gate sections 8 and 9 in the lowered position.

In the absence of a longitudinal removable partition 3 and a building vessel occupying the entire width of the dry dock (Figures 1 and 3), the sections of the main shutter 8 and 9 are installed with struts 17.

The inflatable seal 22 between sec-: ci mi is blown with compressed air.

Chamber 1 with the launching vessel 13 is separated from the rest of the dock by intermediate valves 10 and 11 in order to allow the vessel 14 to exit without stopping work in chamber 2.

To remove the vessel 14, it is necessary to fill the chamber 1 with water, discharge compressed air from the inflatable seal 22W, lower the gate sections 8 and 9 together with the struts 17 into HHiiiy 24, remove the vessel 14 from the dry dock.

291

The vessel, if it is necessary to mount the longitudinal removable partition 3 along the entire length of the dock, is carried out as follows.

The sections of the shutter 8 and 9 together with the struts 17 are sutured into the vertical position of the recess 24 from the contact of the stop 16 with the strut 17s and the inflatable seal 22 is blown with compressed air between the sections, the chamber 1 is deflected, the longitudinal removable partition 3 is set. If necessary, compartments 5 and 4 are separated from compartments B and 7 by transverse intermediate closures 10 and 11, compartments 5 and 4 are filled with water.

Sections 8 and 9 together with Kocam-i 17, the ballast compartments of which 1: 8 and 19 are filled with water, are lowered into the bottom 24, the ballast compartments 18 are blown; And 19 removable struts 17 and they grow around the hinge 20, lift in a vertical position. The compressed air from the ballast compartments J8 is discharged to the atmosphere, the ballast compartments 18 are filled with water, and the removable struts 17 due to the off-center load applied during the purge of compartments 19 are inclined in the cTopohy dock. Then the compressed air from the ballast compartments 19 is discharged into the atmosphere, the retractable struts 17 are lowered into the rig 23, the vessel is introduced into the compartment 4 and 5, and the sections of the shutter 8 and 9 are raised to the vertical position, leaning with one side on the longitudinal partition 3, the compartment 4 and 5 is drained.

The withdrawal of the vessel 12 is carried out by filling the compartment 4 with water, lowering the section of the shutter 8 into the niche 24 with the subsequent withdrawal of the vessel from the compartment.

It is necessary to enter into the dock the vessel, the dimensions of which require the removal of the longitudinal partition, this operation is one of the following: the compartments 4 and 5 are filled with water, the ballast compartments 18 and 19 of the removable struts 17 are blown and they rise to a vertical position, compressed the air is discharged from compartments 19 to the atmosphere, the ballast compartments 19 are filled with water, and the struts slope away from the dock; after the compressed air has been discharged from the ballast compartments 18 and filled with water, the removable SUBSETS 17 are lowered onto the gate sections 8 and 9, the removable longitudinal partition 3 is removed.

If chamber I is not separated from chamber 2 by transverse intermediate closures, the longitudinal partition can be removed even when the dock is full,

those. There is no additional operation for drying the camera 1.

The width of the dry dock chamber can be installed several longitudinal partitions.

Claims (1)

A DRY DOCK containing a chamber with longitudinal removable partitions and a hinged shutter with struts pivotally connected to the bottom of the dock and made with the possibility of their raising and lowering, characterized in that, in order to more efficiently use the working area of the dock, its bottom is made niches for placement of corresponding struts in the reclined position, oriented from the hinge of each strut into the dock.
