Description

Lowering device for underwater probe {Depressing Device for Towfish}

The present invention relates to an apparatus for lowering underwater tow (Towfish), and more particularly, to a body equipped with a device for acquiring underwater information, the body in the underwater tow (Towfish) towed in the water by a ship It is installed on both sides of the Toowe is an apparatus for lowering the underwater probe (Towfish), characterized in that it comprises a depressor (Depressor) for preventing the lifting in the water by the traction force of the ship.

Recently, attention to marine resources and problems of marine pollution have been highlighted, and equipment for obtaining marine information more accurately has been developed.

Among the equipment, the spotlight is currently being used as a side scan sonar system using a towfish, which is mainly used for marine environment survey, needle and underwater object search, artificial reef survey, and fish detection. .

The system is equipped with observation equipment and allows the underwater probe (Towfish) and the underwater probe (Towfish) to obtain the underwater information to be towed by the ship and serves as a communication line between the vessel and the underwater probe (Towfish) It comprises a traction cable and a signal processing and control unit for processing the information sent through the traction cable and controls the underwater probe (Towfish) and an output unit for outputting the information of the signal processing and control unit.

As described above, the underwater expedition body (Towfish) is towed by the ship serves to obtain the underwater information, which is possible by the ultrasonic apparatus built on both sides.

In the ultrasonic apparatus, a ceramic vibrating element is mainly used. The ceramic vibrates when the electrical signal is applied, the same as the frequency of changing the negative and positive of the electrical signal. There is a characteristic that an electrical signal is generated.

Therefore, according to the ceramic vibrating element using the characteristics of the ceramic, it is possible to generate ultrasonic waves in the water and simultaneously receive them.

On the other hand, the underwater probe (Towfish) is equipped with horizontal and vertical tail wings at the rear to prevent the vibration, such as rolling and pitching caused by the shaking of the left and right and up and down.

And the underwater probe (Towfish) is a structure in which the point to which the towing rope is connected exactly located in the buoyancy center of the underwater probe (Towfish) prevents the tilting of the underwater probe (Towfish) when towing .

In addition, the tow rope connecting the underwater probe with the ship to be towed by the ship is arranged a communication line for transmitting electrical signals on the inside and a polyurethane jacket with a relatively high tensile strength on the outside. It is comprised by forming so that a communication line may be enclosed.

Therefore, the tow rope is to be able to perform the role of the communication line and the traction line at the same time.

In addition, the signal processing and control unit and the output unit processes the information obtained from the underwater explorer (Towfish), and functions to control the underwater explorer (Towfish) to function it is sufficient that a conventional computer and monitor system.

As described above, the side scan sonar system using a towfish transmits ultrasonic waves from the towfish to the water while the ship tow the tow cable to the towing cable. Or it is a system for receiving and outputting underwater information.

Thus, the most important and difficult point in the operation of the system is the determination and maintenance of the Towfish altitude (where the altitude of the Towfish is the height from the bottom perpendicular to the water).

The altitude for obtaining the optimal ultrasound image of the underwater fish is about 10% of the search range of the underwater fish, and the ultrasonic signal obtained through the underwater fish is the optimal image. In order to express, it is preferable that the altitude of the underwater fish is at least half the depth of the water.

In fact, in the process of operating the underwater shooting system using the underwater fish (Towfish) is a phenomenon that the underwater fish (Towfish) rises on the water surface, it is difficult for the underwater fish (Towfish) to maintain the above-mentioned altitude, This is due to the lifting force of the tow rope connected to the ship and the ship, the higher the speed of the ship is the deeper the flotation of the ship (Towfish).

 Conventionally, in order to prevent such a phenomenon, a method of increasing the weight of the towing rope and underwater fish (Towfish) or slowing the speed of the vessel towing the underwater fish (Towfish) has been used.

However, the conventional method as described above has a problem in that efficiency is lowered in terms of operation of the system. Furthermore, in order to arbitrarily change the altitude of the towfish, only the method of adjusting the speed of the towing vessel is utilized, so that the altitude of the towfish is not precisely controlled. Towfish had difficulty obtaining clear and accurate information underwater.

Therefore, the development of a device for solving the above problems is required.

The present invention has been made to solve the above problems, the object of the present invention is to prevent the underwater flotation of the underwater fish (Towfish), the optimum underwater fish (Towfish) for the acquisition of accurate underwater information It is to provide a device that effectively controls to maintain the altitude.

An object of the present invention is installed on both sides of the body of the underwater fish (Towfish) underwater characterized in that it includes a depressor (Teefish) to prevent the underwater fish (Towfish) is raised in the water by the traction force of the ship This is achieved by the lowering device of Towfish.

In addition, another object of the present invention is a measurement unit for measuring the altitude of the underwater probe (Towfish) and a central processing unit for calculating and processing the altitude measured from the measurement unit and receiving a signal from the central processing unit (Towfish) It is achieved by the lowering device of the underwater fish (Towfish) characterized in that it further comprises a drive unit for driving the depressor (Depressor) so that the altitude of the) can be changed.

The present invention is installed on the side of the body of the underwater fish (Towfish) Depressor and the measurement unit for measuring the altitude of the underwater probe (Towfish) to prevent the lifting of the underwater (Towfish) It is composed of a central processing unit for calculating and processing the altitude measured from the measurement unit and a drive unit for driving the depressor so that the altitude of the underwater probe can be changed by receiving a signal from the central processing unit Underwater flotation of the tow is prevented, and there is a feature to effectively control the tow to maintain the optimal altitude for obtaining accurate underwater information.
