Description

Towed array sonar with cooling apparatus

The present invention relates to a towed sonar with a cooling device. More specifically, when the submarine is equipped with a tow-type sonar cooling device, the sensor is cooled by sea water or fresh water to automatically supply coolant when the ambient temperature of the winch rises above a certain temperature during the anchorage of the submarine. It relates to a tow-type sonar which can be cooled by cooling.

Sea areas with high sea temperatures, such as the Hormuz Strait or the Mediterranean Sea, and shallow seas, such as the Gulf of Peru and the South China Sea, where the submarines have short detection ranges are urgently needed to increase the detection range.

Magnetic Anomaly Detection (MAD) has been used as a complement to acoustic sensors for non-acoustic sensors in the coastal waters.However, there is a high probability of false positives due to the large amount of local magnetic changes and high ambient noise. Has operational limitations.

On the other hand, when the acoustic coating is applied to the submarine hull, it is possible to significantly reduce the reflected wave for the sonar with medium or high frequency transmission, but it has been found that the acoustic coating is ineffective for the low frequency sonar. In order to reduce the reflectance of low frequency sound waves, the thickness of the coating or the acoustic tile should be increased, but the weight of the submarine is greatly increased, and thus practical coating is impossible.

Therefore, to enhance the submarine detection capability offshore, the use of low frequency receiving towed sonar has emerged as the only alternative.

Most recently built submarines are equipped with towing sonars for long-range and low-frequency target detection, and will be installed in future submarines.

In particular, the tow or winch is wound around a cable and sonar sensor, and is configured to be deployed and collected underwater during operation. However, when the water submerged in a hot summer submarine, the temperature of the exposed casing of the sonar rises, which may cause deformation or failure of the sensor tube having a sensitive structure.

In order to prevent this, a method of separating and storing the whole winch has been proposed, but it is difficult and uneconomical to remove and reinstall.

Some overseas navies that have installed and operated winches in casing require equipment to remove and reinstall tons of winches, as the entire winch is separated and stored. Separate equipment is required. It is also difficult and uneconomical to remove and reinstall.

In addition, the summer temperatures of the Korean peninsula are continuously rising and entering a subtropical climate. Therefore, when the submarine equipment is mounted, heat deformation should be considered. The submarine currently in operation is equipped with a towed sonar, but the technology for the cooling system is not applied.

The present invention is to solve the above problems, the present invention is to cool the surrounding area of the sensor by using sea water or fresh water in the state of equipped with a cooling device of a tow or a submarine in the submarine's ambient temperature of the winch at the time of anchoring the submarine If the above rises, the purpose is to automatically cool the supply of cooling water.

According to the present invention as a technical idea for achieving the object of the present invention, in the towing type sonar having a horizontal winch (1a) or a vertical winch (1b) on the upper portion of the submarine, the winch (1a) 1b of the Tow-type sonar characterized in that the sprinkler 10 is installed on the upper side or the side, and lowers the ambient temperature of the winch (1a) (1b) by directly spraying the fresh water or seawater using the sprinkler (10). To present.

Further, according to the present invention, in a tow-type sonar having a horizontal winch 1a or a vertical winch 1b on the upper part of a submarine, seawater or fresh water is used around the winch 1a, 1b provided on the upper part of the submarine. It is provided with a controller 50 for direct injection, one side of the controller 50 and the temperature sensor 51 is connected, another side and the pump 52 is connected, the other side of the sprinkler 10 ) And a valve 53 to determine a cooling water passage to be supplied to the cooling plate 20, and detects the ambient temperature through the temperature sensor 51 connected to the controller 50, and when the temperature rises above the reference value. By operating the pump 52 to supply the cooling water to the sprinkler 10 or the cooling plate 20 provides a tow-type sonar, characterized in that the cooling by direct injection or indirect cooling.

As described above, the cooling device of the tow-type sonar according to the invention is a cooling device using sea water and fresh water around the ship, and can be applied without changing the existing winch, and reduces the high temperature around the winch to prevent the deformation of the sonar sensor to prevent the replacement cycle. It can be extended and very economical.

In addition, the present invention can reduce the cost because the use of the surrounding sea water or fresh water, and can be quickly operated without the need for reinstallation work compared to the detachable tow-type son when emergency departure is required.

Hereinafter, with reference to the accompanying drawings, the configuration and operation of the embodiment of the present invention will be described in detail.
