Description

 The present invention relates to the field of emergency communications technology, in particular to means of wire communication used in emergency situations for communication with submarines.

 Currently, a device is known for releasing a communication cable with a submerged submarine (British Patent 1266528, class B 66 D 3/28, 1972).

 In emergency conditions, when the submarine lies on the ground, the personnel releases a cable with an emergency buoy from the central compartment in order to have emergency telephone communication with the rescue ship. The device consists of a cable and telephone sets, while one of the devices is in a strong submarine case, and the other is outside a strong submarine case, in the buoy itself.

 The disadvantage of such a device is that it does not provide reliable communication in an emergency due to the frequent failure of the mechanical elements of the cable release device. In practice, as a rule, emergency communication buoys come off the submarine hull. Communication with sunken submarines is carried out by divers who can penetrate into the durable submarine body through torpedo tubes.

 The closest in purpose, technical nature and positive effect to the claimed device is a light-diving telephone exchange TSLV, described in the book of I.V. Merenov and other athlete-light diver. M .: Military Publishing House of the Ministry of Defense of the USSR, 1961, p. 91. This station is designed to provide telephone communication light diver with the surface of the reservoir, ie with a supply vessel. The station consists of two parts: underwater (headset of a working light diver) and surface (headset of a safety light diver), interconnected by a three-wire cable. The headset of a diver working easily consists of a telephone, a microphone box and a plug box, interconnected by segments of a two-wire cable. The headset of an easy-to-diver insurer consists of a headset, a chest microphone and a connecting device.

 The disadvantage of the prototype is the inability to transmit and receive messages on it to the submarine in an emergency.

 The purpose of the invention is the provision of emergency communication diver with a submarine.

 This goal is achieved by the fact that in the diving telephone exchange, containing the headset of a safety diver, consisting of a telephone and a microphone, and a headset of a working diver, consisting of a telephone and a microphone, interconnected via a plug box, the first and second transforming units and two transceiver are additionally introduced amplifying blocks, the converting blocks being connected to the respective transceiving amplifying blocks by means of a fiber optic cable, the first converting the unit is removably mounted in the upper part of the submarine periscope, and the second conversion unit is installed in the lower part of the periscope in the submarine housing together with the second transceiver amplifying unit, and the first transceiver amplifying unit is inserted into the headset of a working diver, each converting unit consisting of a lightproof enclosure, inside of which a collecting lens and a concave mirror are arranged sequentially, in the focus of which a light-emitting and light-receiving element is installed.

The set of essential features of the proposed device provides improved communication reliability due to the fact that information on the submarine and from the submarine goes directly to the diver via an optoelectronic communication system, using the standard periscope of the submarine as an optical connector. The emergency communication device is shown in the drawing and contains:
1 - a headset of a working diver, which serves to enter into negotiations with a safety diver;
2 - a headset of a safety diver, used to negotiate with a light diver;
3 - plug box for connecting two headsets;
4 - a regular submarine periscope, consisting of a vertical telescope and an optical system located inside the tube and serving to provide input and output of optical radiation into the durable submarine hull to the periscope eyepieces mounted on its base;
5 - a converting device that provides coordination of linear and angular apertures of the optical cable and the entrance pupil of the periscope and is located both on the basis of the periscope of the submarine and in its upper part;
6 - fiber optic cable (FOC) is used to transmit optical signals through it from converting devices;
7 - transceiver amplifier blocks, consisting of a transceiver amplifier, telephone and laryngophones, used to transmit, receive and amplify transceiver signals. They are located on a submarine and directly under the diver’s wetsuit. The power of the transceiver units is carried out from a DC source with a voltage of 9 V (battery type "Krona").

 The conversion device 5 consists of a light-tight housing with latches 8, a light-emitting element 9 and a light-receiving element 10, a collecting lens 11 and a concave mirror 12. The light diver under the wetsuit has a transceiver amplifying unit 7, which includes optical laryngophones and telephones (fixed under the light diver's helmet); the transceiving amplifier unit is connected to the wok 6 with the converting device 5. The converting device 5 is fixed with latches in the upper part of the periscope of the submarine 4. The converting device 5 is also fixed in the lower part of the submarine and connected via the wok 6 to the transceiver unit 7 (not shown) .

 The device operates as follows.

 In an emergency, when the submarine crashes and lies on the ground, a diving vessel comes to this area. To establish communication with a distressed submarine, a diver is lowered. The diver descends onto the emergency submarine, takes the conversion device 5 and fixes it on the periscope of the submarine 4. Thus, the diver’s transceiver telephone path with the submarine is formed: an optical laryngophone (under the diver’s helmet), transmitting amplifier unit 7, wok 6, conversion device 5, the upper end of the periscope of the submarine 4, the conversion device 5 (on the submarine), the wok 6, the receiving-amplifying unit 7 and the telephone. The same path, only in the opposite direction, is also formed from the submarine to the diver. After that, two-way telephone communication of the light diver with the submarine is carried out in the process of rescue operations. In this case, when the diver speaks, the acoustic wave excites mechanical vibrations of the laryngophone membrane of the transmitting amplifier unit 7, which are converted into an electrical signal using an optoelectronic device as follows. The light beam from the transmitting amplifier unit 7 through the wok 6 enters the light emitting element 9, a concave mirror 12, collecting the lens 11, the optical system of the periscope of the submarine 4, on the conversion device 5 (which is located on the submarine) wok 6, the amplification unit 7, which is converted by the photodetector into an alternating electrical signal, the frequency of which is also equal to the frequency of the acoustic wave.

 Using such a device will allow the diver to transmit and receive the necessary information from the central post of the submarine and report to the rescue vessel.

 The reliability of communication with a submarine lying on the ground in an emergency increases several times in comparison with the prototype. The quality of the telephone channel is improved, since the use of optoelectronics eliminates echo signals, crosstalk, interference, etc.
