Marine tow line array double-wing automatic fixing depth device

Abstract

Entrust the ocean haulage line, the double wing settles automatically and equips deeply, its bearing and pressing to have inside hull body has already sealed completely the set of the function a tube,driving organization gearing in the set the tube, battery set, communication and control mold piece arranges respectively the department is after the set take care of before, the compass mold piece arranges after communication and control mold piece of department, the depth spreads the upper part that the feeling machine arranges in the battery set, the communication coil arranges in the depth and spread the upper part of the feeling machine; The upper part which bears to press a hull body contain two conjunction terraces, linking terrace to have to lock tight organization up; Drive organization from the electric motor, decelerate a machine, allied stalk machine, silk, put a pole to constitute, the upper part which puts a pole stretches out in bear to press the outside of the hull body and wing plank to install stalk solid connect. This equips of drive the organization simple tightly packed, operation credibility, wing plank action intelligent, respond quickly, have another heavy sealcompletely structure, work to can't take place breakdown, either because of water with long hours in the underwater, exploitation's locking tight organization can quickly and expediently with drag along a cable conjunction or from drag along a cable up unload, easy to drag along the cloth of cable to put.

Description

technical field [0001] The invention belongs to an automatic depth-determining device for a towed cable line array on the sea in seismic exploration, and the automatic depth-determining device belongs to an external device. It mainly uses the principle of lift generated by the wing plate relative to the water flow to adjust the depth of the towline, and the shape adopts a streamlined design, so less fluid noise is generated in the seismic frequency band during operation. Background technique [0002] The offshore towline used for seismic exploration requires good straightness during operation. Because it is relatively long, when the towing speed is low, the middle part will appear arched or suspended, so it is necessary to add a depth-fixing device in the water. Automatically adjust the depth of the towline to ensure the straightness of the towline. The main disadvantages of the existing depth-fixing device are: poor reliability of the driving mechanism, insensitive action ...
