Description

Video unit for underwater surveillance

The technical solution relates to the components of periscope devices and can be used in structures designed to monitor the underwater situation in the water area of an underwater vehicle or surface ship.

A device according to the Federal Republic of Germany patent No. 3908575 is known for observing the underwater situation of a ship’s ship’s hull, which is a passive optical system using an observation window made of flat glass. The disadvantage of this device is the limited viewing area.

To expand the scope of the review allows the device according to the patent of Germany No. 4023322. It contains a video block output from the underwater vehicle and freely floating in the water column, recording the underwater situation around the vessel.

Information from the video block is transmitted through the light guide to the visual observation post of the underwater vehicle. The disadvantage of this device is the ability to detect floating in the water column of a video unit by a surface ship or enemy aircraft.

The closest in technical essence to the claimed one is a video unit mounted on the underwater part of the ship’s hull for observing the underwater situation, according to the utility model certificate of the Russian Federation No. 9073. It contains a porthole made of glass of a spherical shape, a hollow body with a flange, a television camera with a zoom lens, located inside the housing, which is hermetically connected to the porthole. The video information of the television camera by electric cables through a sealed current lead is transmitted inside the ship's hull to the visual observation post. The disadvantage of this device is its limited angle of view.

The objective of the proposed solution is to increase the angle of view of the device.

a porthole, a robust housing with a flange, a television camera with a zoom lens, located inside the housing, which is hermetically connected to the porthole, characterized in that the television camera is installed in an electromechanical scanning device in azimuth and elevation.

Presented in the figure, the drawing explains the essence of the device.

The proposed device (Fig. 1) contains a robust housing 1 in the form of a hollow cylinder with a flange. From the side opposite the flange, the housing 1 is hermetically connected with a spherical porthole 2, which is made of glass that can withstand high pressure and bullet effects, transmitting light rays of both visible and infrared range. The housing 1 and the porthole 2 are connected to each other using an adapter ring 3, the material of which has an expansion coefficient equal to the coefficient of expansion of the glass of which the porthole is made 2. Inside the housing 1 there is a television camera 4 with a zoom lens 5. The television camera 4 is installed in an electromechanical scanning device 6 in azimuth and elevation. The equipment located inside the housing 1, through a sealed current lead by electric cables, is connected to the equipment located in the visual observation post (not shown in the figure).

The inventive video block by the flange of a sturdy hull 1 feps on the underwater part of the ship.

The device operates as follows.

The video signal of the television camera 4 is transmitted via cable to a television monitor located in the ship’s visual observation post, where it can be watched simultaneously by all those present, and can also be recorded on a video recorder or PC. The angle of the field of view increases significantly when you rotate the television camera 4 using an electromechanical device 6 on command from the visual observation post. Electromechanical device 6 provides a turn in azimuth within ± 45 ° and in elevation ± 30 °.

The tests of the prototype video block showed its effective operation.

Claims (2)

1. A video unit for observing the underwater situation, comprising a porthole made of spherical glass, a robust housing with a flange, a television camera with a zoom lens located inside the housing, which is hermetically connected to the porthole, characterized in that the television camera is installed in an electromechanical scanning device in azimuth and corner of the place. 2. The video block for observing the underwater situation according to claim 1, characterized in that the porthole is connected to a strong body through a transition ring, the material of which has an expansion coefficient equal to the coefficient of expansion of the glass of which the porthole is made.
