Description

The utility model relates to sea buoys, in particular to emergency release buoys.

In the design of ships and vessels, special attention is paid to the development of emergency rescue devices to assist the emergency ship and rescue its personal staff. These devices include communication equipment for sending signals from an emergency ship and communication with assistance ships: an emergency signal buoy with a telephone, emergency buoys and an alarm system.

The emergency signal buoy is a hollow float of positive buoyancy, equipped with a signal lamp, a telephone and a radio station. Known beacon type T-616 SRT, which is thrown to the surface through a device for firing simulated cartridges. A folding whip antenna is mounted in the upper part of the buoy, which straightens after the buoy emerges under the action of a spring, and the transmitter mounted in the buoy starts transmitting coded distress signals on a 1.43 m wave for 14 hours [V. Solovyov and others. Communication at sea. L., Shipbuilding, 1978].

Known antenna device for rescue buoy. RF patent for PM No. 46610, 2005, Cl. H01Q 1/34, B63B 51/02. Contains a telescopic antenna and a radio transmitter mounted on an emergency buoy.

Emergency rescue buoy is also known. RF patent for ПМ №92403, 2010. The buoy contains a shell-case in which various sensors are installed, cl. B63C 9/18.

It is known emergency device for submarines, containing associated with the designated submarine through the site of recoil and mounting the buoy, in the upper part of which there is a receiving antenna, and in the body - signaling devices, including radio transmitters equipped with parachutes and pyrotechnic mixtures, a receiving-decoding unit and a control unit actuators for triggering alarm devices. “Naval equipment”, No. 3 1971, p. 33.

The disadvantages of both analog and prototype are the long search time for the submarine and the likelihood of its detection.

The purpose of the utility model is to reduce the search time for a sunken submarine and increase the likelihood of its detection.

This goal is achieved by the fact that the emergency device for the submarine, containing associated with the designated submarine through the return and fastening unit of the buoy, in the upper part of which there is a receiving antenna, and in the body - signaling devices, including radio transmitters equipped with parachutes and pyrotechnic mixtures, receiving a decoding unit and a control unit for actuators for triggering the signaling devices, while the receiving-decoding unit consists of a frequency selector connected to the receiving antenna by its input and an automatic a signaling device selection mutator, the input of which is connected to the output of the control unit for actuating actuators of the signaling device, while the automatic signaling device selection switch is made in the form of a finder according to a pulse counting circuit of a certain duration, and the receiving antenna is isolated from water and hermetically connected to the output of the frequency selector.

The emergency device shown in FIG. 1, in FIG. 2 is a block diagram of the connection of elements; FIG. 3 - signaling device.

The device consists of a buoy 1 connected through a node 2 recoil and mount (cable) with a sunken submarine. Signaling devices 3 are placed in the case of buoy 1. A receiving antenna 4 is installed in the upper part, which is insulated from water and hermetically connected to the input of the frequency selector 5 located in the case of buoy 1 and connected by its output to the automatic switch 6 of signaling device 3. Selector 5 and switch 6 constitute a receiving-decoding unit.

The output of the switch 6 is connected to the input of the actuator control unit 7 of the signaling device 3. The selector 5 and the switch 6 are connected to a power source 8.

Each signaling device 3 includes an actuator 9 for launching, a capsule 10 with a pyrotechnic mixture, folded with a parachute 11, a radio transmitter 12 with an autonomous power source 13 and an antenna 14.

The operation of the device is as follows.

At the time of the accident, automatically or manually, the hull of buoy 1 of the device is separated from the submarine in the underwater position. Buoy 1 under the influence of positive buoyancy floats to the surface and is held above the submarine using node 2 (cable). Buoy 1 floats to the surface of the water or be submerged if the length of the cable is less than the depth in the area where the sunken submarine is located or when the cable is flooded.

Search ships, after arriving in the area where the sunken submarine is supposed to be located, emit a long-wave radio signal-command to shoot signaling devices 3. The signal-command, having reached antenna 4, enters the frequency selector 5, which analyzes the received signal in frequency and sends an automatic switch 6 to the switching unit 7 Block 7, depending on the frequency of the signal command sends a signal to the actuator 9 of one of the signaling devices 3. The necessary signaling device 3 under the influence of the actuator 9 pouring in. The pyrotechnic smoke-generating mixture from the capsule 10 is ignited, the parachute 11 opens, the radio transmitter 12 receiving power after actuating the actuator 9, starts to emit signals for direction finding. The supporting effect of the parachute 11 allows the transmitter 12 to stay above the water for a certain time, which provides sufficient exposure for direction finding. The presence of a combined and pyrotechnic designation provides reliable detection of sunken submarines.

Thus, the separation of signaling devices is carried out only by the encoded command signal transmitted by the search forces. In addition, the presence of a frequency selector 5 and an automatic switch 6 ensures the separation of the signaling device that has the optimum frequency of the transmitted alarm signal for the conditions of a given region. When searching for a sunken submarine using the proposed device, the search time is significantly reduced and is practically determined only by the time required for the direction finder to the area of the alleged location of the sunken submarine.
