KR200335091Y1 - Tail fin protection structure for underwater towed body - Google Patents

Abstract

The present invention relates to a device for safely recovering to the water phase without being lost even if the tail (Fin) of the ultrasonic bottom flaw detector to be pulled underwater by the water vessel of the water hitting or tangling underwater. More specifically, the tail portion of the towing body according to the present invention maintains the insertion state in the main body of the towing body is provided with a direction maintenance tail wings designed to be freely released when hit the obstacle, when towing by the towing vessel In order to prevent the tail wings from being lost when they are separated from the towing body, a steel wire is connected between the tail wing and the body of the towing body, and the strap is stored in a proper space inside the body to receive water resistance during towing of the towing body. It is designed to reduce marine pollution and economic losses caused by the loss of tail wings.

Description

Tail fin protection structure for underwater towed body}

The present invention relates to a device for preventing the loss of the direction of the tail wing installed in the underwater tow, more specifically in order to prevent the tail wings are lost when towing from the body of the tow when towing by the towing vessel It is connected between the tail wing and the main body of the towing body with a steel wire, and the string is stored in a proper space inside the main body so that it is installed so as not to receive water resistance during towing, which reduces marine pollution and economic loss caused by the loss of the tail wing. It's about things.

Conventionally, due to the lack of awareness of environmental pollution of the seabed, there are many fishing gears and wastes in the seabed near the land, and the tail wings of the towing body or towing body are caused by these underwater obstacles while operating the towing body. There is a problem that it is very likely to be repeatedly lost or lost, and if it is lost by replenishing the missing tail wing, there is a problem of economic loss due to marine pollution and loss of the tail wing by the missing tail wing.

The technical problem to be achieved by the present invention is to recognize the above problems, and even if the tail wing attached to the underwater traction body is lost from the main body is lost between the direction of the tail wing and the main body to prevent the environmental pollution of the seabed ( Strap), and to prevent the tail wing loss prevention device of the underwater towing can be stored in a suitable place of the body by folding the steel wire (string) into the body so as not to receive water resistance during towing.

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

2: towing ship 4: underwater obstacle

6 towing line 8 towing body

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 directional retaining tail blades inserted into the traction body with a steel wire of a sufficient length, and inserts the tail wings into the traction body, and connects the steel wires (strings). Is folded and stored in a suitable space inside the towing body to eliminate water resistance by the line during towing.

Referring to Figures 1, 2 and 3 in detail the constituent means according to the present invention, first, an underwater traction body 8 present in the seabed by using the traction ship 2 for the seabed survey as shown in FIG. ), When excessive force is frequently applied to the tail wing 10 for maintaining the direction of the traction body 8 by the underwater obstacles 4 such as rocks, fishing nets, etc. that exist in the water. . In this case, the tail wing 10 inserted into the main body 12 of the traction body 8 is separated from the main body 12, and the detached tail wing 10 is connected to the main body 12 by a string ( 14) the tail wings 10, once towed together with the main body 12, are suspended in the water without being lost and thus the tail wings 10 are also recovered when the tow body 8 is recovered on the surface or above the ground. By recovering together, the tail wings are prevented from being lost to the seabed. The constituent means for fixing the tail wing and the steel wire (string) by drilling a hole in a position that can easily escape the obstacles on the seabed while minimizing the resistance of the water when the tail wing is separated from the main body of the traction body ) In addition, when the steel wire fixed to the tail wing is fixed to the towing body, when the towing vessel is towed, it is connected between the towing ship and the underwater towing body so that the towing steel wire (string) is fixed at one point of the towing body. It is recommended to fix the steel wire in a place where steel wire can be easily stored without generating additional water resistance, and the means for fixing the body and the steel wire (string) by drilling a hole in one part of the body to connect the steel wire or the structure of the body Tie on and fix it. The steel wire may have a strength such that the steel wire or nylon does not easily break due to the force acting upon the obstacle or hitting the seabed obstacle.

The present invention implements a device for preventing the loss of the tail wing of the underwater towing due to underwater obstacles. The tail wing of the towing body and the main body of the towing body with a steel wire to prevent loss of the tail wing by preventing the loss of the tail wing to prevent environmental pollution of the seabed and the loss of the repeated tail wing. It is effective in reducing economic losses.
