Abstract

The invention discloses an underwater oil-filled towing cable drag adjustment device, which belongs to the technical field of underwater drag detection. The device includes tension gauge, electric slip ring, control cabin, buoyancy regulator, propeller and damping umbrella; Installed inside the damping umbrella; the oil-filled towline is connected to the interior of the control cabin through the tension gauge and electric slip ring; the propeller and the damping umbrella respectively generate thrust and resistance to act on the oil-filled towline and pull the oil-filled towline to unfold; adjust the buoyancy The regulator changes the pitch of the control cabin. When the head is bowed, the oil-filled towline is pulled up, and when the head is raised, the oil-filled towline is dragged to sink, so that it has the ability to adjust the depth of the underwater oil-filled towline. The invention has the function of automatically adjusting the depth of the towline, adopts the hybrid power of the sea current resistance and the propeller, the traction towline can be normally deployed and heaved, and has the ability to provide towing force for the towline for a long time and in a wide water depth.

Description

technical field [0001] The invention relates to an underwater oil-filled towing cable towing adjustment device, which belongs to the technical field of underwater towing detection. Background technique [0002] Ocean exploration is a key technology for ocean development. As an important technical means in the field of marine detection, the underwater line array detection technology has been continuously developed and developed in recent years. In the underwater line array detection system, the line array is usually installed in the oil-filled streamer. The oil-filled towline is expensive, and its length is often hundreds of kilometers. When the towline is retracted and deployed underwater, it needs to have a pulling force along the length of the cable; otherwise, the towline will bend, causing the line array to fail, or even Stranding damage occurred in the towline. At the same time, the density of seawater changes with depth, so to meet the needs of working in different ...
