The window of the underwater vessel

 

(57) Abstract:

Usage: in shipbuilding, particularly in submarine vessels. Essence: the window is made of two parts - protective rings-screen and security screen. The protective screen is made in the form of a transparent disc of plastic material, which is fixed by means of waterproof combined seal metal ring and force the screen is made in the form of laminated glass block of hardened plates silicate glass, interconnected via a transparent adhesive polymer material, and is secured in the clip window. The cavity between the protective and security screens filled with fluid. 1 Il.

The invention relates to the field of shipbuilding and can be applied on different underwater vessels (apparatuses).

Known window containing power disk of transparent material secured in the holder by means of the sealing and clamping ring, and the cover disc of transparent material and attached to the yoke by screws additional ring between the disks formed by a cavity filled with fluid.

The disadvantage of this design are insufficient nudegirlfriends survivability of the porthole.

This objective is achieved in that the cover disc is made of plastic material and secured in the hole with additional rings through a watertight seal that is located on the side surface of the protective disk and along the perimeter of its end surfaces, an additional ring is made of two parts connected by screws, and power comes in the form of laminated glass block of sheets of silicate glass, connected by a transparent adhesive polymeric material, and each of the seals of the power drive and a protective disk is made a combination of a rubber o ring and a layer of rubber-like sealing material, and the space between the disks is sealed by means of additional rubber rings.

The drawing shows the cross section of the porthole.

The window consists of two independent structural elements of the protective screen and security screen, they can be installed and understand independently from each other. In clip 1 sealed power unit 2 on the basis of silicate-strengthened glass with sealing rubber-like material 3 and SS="ptx2">

Rings 4 and 5 are located in the slots of the cage 1 and the ring 6. The clamping ring is fixed with screws and locking unbendable washers 7. The circuit block 2 and the shell 1 is located a sealing rubber-like material 3 after vulcanization forms with o-rings 4 and 5 dense composite profile.

On top of the cage installed additional ring-screen, in which the upper 8 and lower 9 using a combination of seals 10 and 11 are sealed safety glass 12 of the organic material. The upper 8 and lower 9 frame drawn between the screws 13. Kontrolka performed using unbendable washers 14. For reliability seal set rubber ring 15. Additional ring-the screen is located at a distance from the power unit, forming a cavity filled with the immersion liquid 16. Sealing the cavity is made of a sealing rubber ring 17. Mount rings-screen performed by the screws 18. This solution seals the cavity allows you to remove and replace the protective screen under water. Filling and draining of immersion liquid in the porthole is made through holes in the upper frame 8.

In the process, the window on the depth of the water pressure environment is howling unit 2. When the bending strength of glass block 12 due to its pliability sags, repeating the path of deflection of the power unit 2. Due to the plasticity of the material glass 12 dangerous voltage from depression it does not occur, the glass remains intact and operation of the illuminator continues. The same thing happens due to technological imperfections of the fabrication, for example, due to underfilling of the liquid in the chamber (cavity), or arising from leaking it.

In the case of cracking all bearing layers of the power block (plates silicate glass) under water as a result of an emergency power unit integrity is not lost, because it is a composite material in which the bearing layer silicate glass plate is attached to the filler - adhesive Proleukin.

Cracked glass remains attached to the adhesive layers, giving rigidity of the power unit, and an adhesive layer start to work on stretching, while maintaining its integrity. (56) USSR Author's certificate N 685548, class B 63 B 19/00, 1977.

The WINDOW of the UNDERWATER VESSEL containing power disk of transparent material secured in the holder by means of the sealing and clamping ring, as well as the discs formed cavity, filled with liquid, characterized in that the said protective disk is made of plastic material and secured in the hole with additional rings through a watertight seal that is located on the side surface of the protective disk and along the perimeter of its end surfaces, an additional ring is made of two parts connected by screws, and power comes in the form of laminated glass block of sheets of silicate glass, connected by a transparent adhesive polymeric material and each of the above-mentioned sealing force of the disk and the protective disk is made a combination of a rubber o ring and a layer of rubber-like sealing material, and the space between the disks is sealed by means of additional rubber rings.

FIELD: electronic industry; building industry; transport; methods of production of protective electrically conducting and optically transparent coatings.

SUBSTANCE: the invention is pertaining to the method of production of the protective electrically conducting and optically transparent coatings, which may be used in electronic industry, transport, and also for realization of the energy-saving technology and in the building industry. The invention presents the method of production of the indicated coatings made on the base of indium oxide on the substrate out of the glass providing for the vacuum magnetron sputtering of the target based on indium and the coating deposition in the aerosphere of the mixture of the inert gas and oxygen on the preheated substrate. At that, first deposit an indium oxide layer of no more than 5-15 nanometers thick on the substrate, subject it to the thermal treatment at the temperature of 200-250°C during 20-30 minutes, then iterate the cycles of deposition of the indium oxide layers and their thermal treatment till obtaining the given depth of the coating. The invention offers the versions of the products made in the form of the protective optically transparent screens for the monitors with the factor of extinction of the spurious electromagnetic radiation of no less than 40 dB, in the form of the glass for the cars, the ships, the pilot cock-pits of the airplanes and in the form of the window glass. The technical result of the invention is an advantage of production of the optically transparent coatings with the electroconductivity of less than 3 Ohm/cm2 at the high strength and stability of its properties.

EFFECT: the invention ensures production of the optically transparent coatings with the low electroconductivity at the high strength and stability of its properties.
