Abstract

FIELD: weapon and ammunition.

SUBSTANCE: method of protecting the objectives of the optoelectronic sight module, which includes the placement and rotation of the optoelectronic sight unit on the horizontal axis of the rotary support device. The lens is protected by rotating the optoelectronic sight block in the direction that provides the least chance of foreign objects entering the entrance pupils of the objectives. On the surface of the optoelectronic unit, there are armoured plates covering the whole surface of it, except for the entrance pupils of the lenses. Armour plates have a thickening, located when the optoelectronic unit is rotated from the side of the most probable direction of foreign objects entering the entrance pupils of the lenses.

EFFECT: increasing the protection of the optoelectronic unit from damage by bullets, debris and other objects.

Description

The invention relates to military equipment and can be used on tanks, infantry fighting vehicles, armored personnel carriers to protect the lens or protective glass of the sight from bullets, fragments and other foreign objects.

Known optoelectronic systems (FLIR Systems, Sagem Defense Security, etc.) [1, 2], designed to search, track and determine targets.

A disadvantage of the known optoelectronic systems is that they do not provide a system for protecting the sight lenses.

A known method of protecting the lens using the wings of the sight of a combat vehicle [3]. To close the shutter of the first lens, it is necessary to move the handle all the way down and turn to the right. To close the shutter of the second lens, the handle should be turned in the lower position to the left until the pipe with the sector on the latch. To open the flaps, it is enough to pull the latch towards you until the pipe with the sector is released, while under the action of the springs the flaps will open.

The disadvantage of this method is the difficulty in implementing, if necessary, ensure the rotation of the lenses around a vertical axis without limiting the angle of rotation.

A known method of protecting an optical device using sashes [4].

The device operates as follows: using the drive mechanism, rotational motion is transmitted through the shafts to the movable rear flaps, which through the hinges transmit rotational-translational motion to the movable front flaps. The trajectory of the movement of the leaves is set by leashes by turning the levers, which, in turn, freely rotate on the axis. Thus, the protection device of the optical device is transferred from traveling to the combat position. The transfer from combat to stowed position is carried out by changing the direction of rotation of the shafts. To increase the viewing angle and reduce the size of the protection device in the combat position, the front flaps should be slightly longer than the rear flaps, which provides them with a greater retraction back behind the protection case.

The disadvantage of this method is the difficulty in implementing, if necessary, ensure the rotation of the optical device around a vertical axis without limiting the angle of rotation.

Closest to the proposed method is a universal Paseo panoramic sight from the company Sagem Defense Securite [1], located on a rotary support device that contains a laser target designator, television and thermal imaging cameras, a laser rangefinder with the possibility of continuous round-scan 360 ° scanning.

The disadvantage of this method is the lack of a protection system for the lenses of the sight.

The technical task of the proposed method is to create protection for the lenses of the optoelectronic unit from damage by bullets, fragments and other objects while ensuring the rotation of the optoelectronic unit around a vertical axis without limiting the angle of rotation.

The problem is solved due to the fact that in the proposed method of protecting lenses of the optoelectronic unit of the sight, including the placement and rotation of the optoelectronic unit on the horizontal axis of the support-rotary device, the protection of the lenses is carried out by turning the optoelectronic unit in the direction that provides the least probability foreign objects entering the entrance pupils of the lenses. In order to enhance protection on the surface of the optoelectronic unit, armored plates are placed covering its entire surface, except for the entrance pupils of the lenses. In addition, armored pads may have a thickening located when the optoelectronic unit is rotated from the side of the most probable direction of foreign objects entering the entrance pupils of the lenses.

The invention is illustrated by drawings:

In FIG. 1 shows an optoelectronic unit on a slewing ring in an unprotected position.

In FIG. 2 shows an optoelectronic unit on a slewing ring in a protected position, where:

1 - optoelectronic unit,

2 - entrance pupils of the lenses,

3 - slewing ring device

4 - armored pads,

5 - thickenings on armored slips.

The proposed method is as follows:

The optoelectronic unit 1 (Fig. 1) with the entrance pupils of the lenses 2 is mounted on the horizontal axis of the slewing device 3, which can rotate around the vertical axis without limiting the angle of rotation. Protection of the entrance pupils of the lenses 2 is carried out by turning (Fig. 2) of the optoelectronic unit 1 in the direction that provides the least chance of foreign objects getting into the entrance pupils of the lenses. With reference to FIG. 1 and 2 of the design of the slewing device 3, this position is the rotation of the optoelectronic unit 1 by the entrance pupils of the lenses 2 down to the horizontal base of the slewing device 3.

In order to enhance protection on the surface of the optoelectronic unit 1, armored plates 4 are placed, covering its entire surface, except for the entrance pupils of the lenses 2.

In addition, in order to enhance protection, the armored plates 4 have a thickening located when the optoelectronic unit 1 is rotated from the side of the most probable direction of foreign objects entering the entrance pupils of the lenses 2.

Thus, the task of creating protection for the optoelectronic unit lenses from damage by bullets, fragments and other objects under conditions of ensuring the rotation of the optoelectronic unit around a vertical axis without limiting the rotation angle has been solved.
