Abstract

Disclosed is a device for safely and safely recovering a tailbed fin of an ultrasonic bottom flaw flaw drawn by an aquatic vessel to a seabed without being lost when it collides with or entangles an underwater obstacle. The tail portion of the towing body maintains the insertion state in the main body of the towing body is provided with a direction maintenance tail wings so as to be freely released when hit the obstacle. The tail blades are designed to connect between the tail blades and the towing body as a root to prevent leakage when the tail wings are separated from the body of the towing body, and the straps are housed in a space inside the body so that they are not subjected to water resistance during towing.

Description

Tail fin holding string for underwater towed body}

The present invention relates to a device for preventing the loss of a tail wing for maintaining the direction installed in the underwater tow, more specifically, when the tail wing of the tow pulled in the water by the ship on the surface is caught by obstacles in the water due to excessive towing The present invention relates to a device for preventing the tail wing from being lost by the detachment of the tail wing.

Our country does not have much information about the ocean, especially about the sea floor. Along with the growing trend of domestic and international awareness of the importance of the environment, not only environmental pollution on land, but also environmental pollution of the ocean is very serious. In addition, from the viewpoint of marine defense, it can be said that the seabed topography information is very important, and object search work due to various sea accidents is frequently required.

In this case, the high speed operation of the ultrasonic flaw detector can be economically provided without the need for divers. However, there is a lot of fishing gear and wastes on the seabed near our country, and there is a high possibility of losing the towing or tail wings of the towing vehicle due to these underwater obstacles during the operation of the towing vehicle. In foreign countries, when operating such an underwater towing body, several tail wings are prepared and lost.

The present invention is devised to solve the above problems, the object of the present invention is to connect the string between the tail wing and the main body so that the tail wing attached to the underwater towing body is not lost even if it is separated from the body, Fold the strap into the body to avoid resistance.

Figure 2B is a view illustrating a tail wing loss prevention device of the underwater traction according to the present invention.

10: tail wing 12: towing body

14: string 16: string storage space

In order to achieve the above object, the present invention connects between the tail blade inserted in the towing body and the towing body with a string having a sufficient length, and when the tail wing is inserted into the towing body, the connecting strap is folded and stored in the space inside the towing body. Let's do it.

Hereinafter, the present invention will be described with reference to the accompanying drawings.

1 is a conventional underwater traction situation for the present invention.

Figure 2A is a side view of a conventional underwater retractor for the present invention.

Figure 2B is a detailed assembly view of the present invention.

Referring to Figure 1 and Figures 2A, 2B to explain the loss prevention device of the tail of the underwater towing according to the present invention, as shown in Figure 1 using the towing vessel (2) for the seabed to investigate the underwater towing ( In the case of towing 8), a case in which excessive force is applied to the tail wing 10 of the towing body 8 by underwater obstacles 4, such as rocks, fishing nets, etc., which are present in the water, occurs frequently. In the above-described case, the tail wing 10 inserted into the main body 12 of the towing body 8 is separated from the main body 12, but the string 14 connecting the tail wing 10 and the main body 12 to each other. The tail wing 10 once removed from the main body 12 is also suspended in the water without being lost, and when the towing body 8 is recovered in the water, the tail wings 10 are also recovered together to prevent loss. .

As can be seen from the above description, the present invention describes an apparatus for preventing the loss of the tail blade tail of the underwater body due to the underwater obstacle. If the fishing net is tangled with the tail wing of the towing vehicle or the wing is hit by an underwater reef, structure, etc. By connecting to the effect of preventing the loss of the tail wing.

Claims (1)

A string connecting the underwater towing body towed by the marine vessel and the tail wing inserted therein; The apparatus for preventing the loss of the tail of the underwater towing body consisting of a space inside the towing body that is to be folded and stored.
