RU2810007C1 - Means for transmitting emergency alert and designating location of emergency submarine under ice - Google Patents

Abstract

FIELD: marine communications.

SUBSTANCE: means of warning about an accident. The means for transmitting an emergency alert and marking the location of an emergency submarine under the ice consists of a housing with a diameter of 190 mm to ensure the release of the means from the standard device of the submarine. The housing contains a hydrostat, an air cylinder, an elastic waterproof container, a battery and a transmitting device. The container has an etching safety valve for bleeding air from it, while on the upper plane of the container there is an antenna device for transmitting a signal through the ice cover.

EFFECT: improved transmission of an emergency alert through ice cover of any thickness is achieved.

Description

The invention relates to the field of marine communications, in particular to means of warning about an accident. During the operation of submarines, including under ice, emergency situations may arise, as a result of which the submarine may be unable to surface and transmit information about the accident.

There are known means that transmit information about an accident from under the ice by bringing the antenna to the surface through mechanical destruction of the ice cover [1], chemical and thermal destruction of the ice cover [2]. The above means transmit information when the ice cover is up to 3 meters thick. The disadvantage of these means is the impossibility of guaranteed transmission of a signal about a submarine accident under ice. When the ice cover is more than 3 meters thick (which occupies about 35% of the Arctic Ocean [3]), signal transmission is not ensured.

A known means [4] transmits a signal about an accident without destroying the ice cover. This device is located on the hull of the submarine, which allows it to float to the lower edge of the ice. The disadvantage of this means is the low probability of the emergency submarine surfacing under the lower edge of the ice cover due to the presence of negative buoyancy. We take this tool as a prototype.

The studies carried out, taking into account the known property of radio transparency of ice, show [5] that when the antenna of the transmitting device is tightly adjacent to the lower edge of the ice or when it is in the air under the ice, transmission of a radio signal through the ice cover is possible.

The objective of the present invention is to ensure that an emergency submarine, unable to surface, would be able to release the proposed means, which would float under the lower edge of the ice and transmit the specified information. The inventive means must allow the transmission of a signal about an accident of a submarine located both under ice and without ice cover.

The design of a means for transmitting a signal about an emergency and marking the location of an emergency submarine is shown in Fig. 1a, 1b. The device consists of a housing 1 (with a diameter of 190 mm to ensure the release of the product from the standard device pl), ascent block 2 (to ensure the initial ascent of the product after release), a hydrostat 3, an air cylinder 4, a transmitting device 5, an elastic waterproof container 6 with an antenna device 7, battery 8, fuse 9, release safety valve 10.

The product is prepared for operation and released from the standard release devices of the submarine at all possible depths. A feature of the proposed product is the possibility of its release while the aircraft is on the move.

Information about the condition of the submarine is entered into the proposed product immediately before use. After leaving the pl release device, the proposed means, due to the positive buoyancy provided by the ascent block 2, begins to rise to the ice surface. When a depth of 20-25 meters is reached, the hydrostat 3 is activated and the air supply from the cylinder 4 is unblocked, which begins to flow into the elastic waterproof container 6. Under the influence of the incoming air, the container 6 leaves the housing 1 and, when filled, deploys the antenna device 7, while opening the fuse 9, which activates the battery 8. The battery 8 supplies power to the transmitting device 5. An air-filled elastic waterproof container 6 with an antenna device 7 located on its upper plane floats to the surface of the ice and, due to elasticity and air pressure, fits tightly to the lower edge ice cover. In this case, excess air in the elastic waterproof container 6 is released through the release safety valve 10, located directly on the container 6. The transmitting device 5, using the deployed antenna device 7, transmits the stored information through operating communication satellites. The transfer is carried out in a receipt-free manner during the time provided by the operation of the battery.

The novelty of this tool is that it allows you to transmit a signal about an accident through ice cover of any thickness. The advantage over existing analogues is that information from a submarine is transmitted from all possible depths of its location, regardless of the thickness of the ice and the position of the submarine: underway or lying on the ground when it is impossible to surface.

The inventive product has a simple and universal design, small weight and size characteristics and can be used from standard devices pl.

The use of the invention will increase the likelihood of detecting an emergency submarine located both under ice and without ice cover, and significantly reduce the time of its search.
