Buoy type submarine periscope and communication device

Abstract

The invention discloses a buoy type submarine periscope and communication device. The technical scheme adopted by the invention is as follows: the buoy type submarine periscope and communication device mainly comprises an invisible housing, a rotary platform, a high-definition camera, an ordinary camera, an electronic gyroscope, a magnetic compass, a stepping motor and a receiving antenna, wherein invisible housing is formed by two hemispherical casings which arranged separately up and down, in a sealing and butting manner; the rotary platform is arranged above the butting position of the two hemispherical casings, and is driven and controlled by the stepping motor arranged below the rotary platform; the direction of the probe of the high-definition camera passes through the center of the magnetic compass along the upper part of the magnetic compass and directly faces to the direction, to which an arrow on one side of the magnetic compass is pointing; the direction of the probe of the ordinary camera is opposite to the magnetic compass on the rotary platform; direction scales are marked in the peripheral direction of the magnetic compass. The buoy type submarine periscope and communication device provided by the invention has the advantages that the possibility that a submarine is detected by enemy is lowered, the concealment and battlefield viability of the submarine are improved, and the buoy type submarine periscope and communication device is mainly applied to submarine periscope and communication.

Description

technical field [0001] The invention relates to the technical field of submarine periscope and communication, in particular to a buoy type submarine periscope and communication device. Background technique [0002] Submarines have unique advantages in naval battles. They can dive to a certain depth, use natural barriers—sea water cover to hide themselves, and then launch a sudden attack, causing the enemy to be caught off guard. But submarines also have their own disadvantages. When scouting the sea surface, they need to float up to the periscope depth and use the periscope to observe the sea surface. This depth is called "dangerous mode" in submarine operations. When the submarine floats up and exposes the periscope, it is easy to expose One's own position was detected by enemy radar or anti-submarine aircraft, and thus suffered a fatal blow.

But submarines also have their own disadvantages. When scouting the sea surface, they need to float up to the periscope depth and use the periscope to observe the sea surface. This depth is called "dangerous mode" in submarine operations. When the submarine floats up and exposes the periscope, it is easy to expose Your own position is detected by enemy radar or anti-submarine aircraft, so you suffer a fatal blow

At the same time, the current underwater communication of submarines has always troubled the development of submarines in various countries. Due to the "skin effect", high-frequency signals are rapidly attenuated when they enter the sea surface and cannot penetrate seawater. Therefore, submarines need to float to the sea surface to get in touch with the ground. Although low-frequency and very low-frequency communications have strong penetration, submarines need very long antennas to receive signals, and the construction of ground stations is huge and costly. Low-frequency communications have a narrow frequency band, small capacity, and low transmission rates.
