Tail fin protection structure for underwater towed body

摘要

The subject innovation relates to a device for safely without stabilizer (Fin) of the ultrasonic flaw detector sea floor towed underwater by a vessel of water is lost even if hit or entangled on obstructions in the water recovered in the water phase. When more traction Specifically tail portion of the detected human body according to the present invention has been for a stabilizer held designed direction to the installation and keep the inserted state in the main assembly of the detected human body to be hits freely leaving the obstacle, by a towing vessel stabilizer are connected to the steel wire (cord) between the tail and the detected human body in order to prevent that lost when separated from the detected human body, and strings are housed in a suitable space in the main body being the water resistance during towing of the detected human body It is installed so that it may have that feature for reducing marine pollution and economic loss due to loss of the tail rotor.
