Description

TECHNICAL FIELD [0001] The present invention relates to an apparatus and a method for manufacturing a protective cover for a linear array towing sensor,

The present invention relates to an apparatus and a method for manufacturing a protective cover for protecting a sonar system line array towing sensor, more specifically, a protective cover can be manufactured quickly and easily, and an inner guide assembly is mounted on a dice assembly The present invention relates to an apparatus and a method for manufacturing a protective cover for a sonar system line array sensor capable of accurately positioning an inner core at a predetermined position of a protective cover.

Generally, a radar, a laser, or an infrared ray is used to detect a target using electromagnetic waves on the land or the air, but a sound signal and a sounding (SONAR) using a sound signal is used to detect a target in the water.

The sonar is a device that can detect a threatened underwater object and enable sailing ships and submarines to sail safely. It is also called a sound detection device or a sound detector.

The sonar is divided into passive sonar and active sonar according to the detection method.

A passenger sonar is a device that detects a submarine by receiving noise from an engine or a propeller at a distance when the submarine sails. It is a line array sonar for towing from a submarine or a ship, a hull attached to the submarine, And a line array sensor for a watershed monitoring sound system.

The active sonar is a device that detects the enemy submarine using the signal that the sound wave generated in the water trap sonar is reflected from the target and returns. It is installed in the front part of the trap, There is adjustable variable depth sonar.

The operating principle of the sonar uses piezoelectric phenomena. When the intensity of the current flowing through the crystal or the ceramic that exhibits piezoelectric phenomenon is changed at a constant frequency, they generate sound waves of the same frequency while vibrating. On the other hand, receiving sound waves from the outside generates electric energy, so by analyzing the electric signals, the components of the sound waves can be detected.

Generally, the sonar has a structure in which a plurality of acoustic sensors are arranged in a specific form, and a wavelength of an acoustic signal generated by each acoustic sensor forming the array structure and an electric signal for driving each acoustic sensor And detects an acoustic signal in a specific direction.

FIG. 1 is a side view showing a protective cover for a conventional sonar system line array towing sensor, and FIG. 2 is a sectional view taken along line A-A of FIG.

1 and 2, a protective cover 10 for a conventional sonar system line array towing sensor is configured to surround a sonar system line array towing sensor 1, and the protective cover 10 has an inner core 20 are arranged at equal intervals.

Insulating oil (2) is filled in the inside of the protective cover (10) to keep it in a cylindrical shape. The protective cover 10 is formed of a polymeric plastic material, for example, a polyurethane material.

However, the conventional apparatus for manufacturing a protective cover for a sonar system line array towing sensor is complicated in its entirety and can not be manufactured quickly and easily, so there is a limit in improving the productivity. There is a problem that the insulation and durability of the protective cover deteriorate.
