Embodiment Construction

[0035] In order to make the above objects, features and advantages of the embodiments of the present invention more clearly and easily understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, but not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

[0036] In the prior art, a wrapping layer is provided between the water blocking layer and the protective layer to make the water blocking layer more round. However, the wrapping layer and the protective layer cannot be tightly connected, and the wrapping layer and the protective layer are easily separated from each other due to the...

Abstract

The invention provides a marine towing cable, which comprises a force bearing unit, a plurality of wire core units, a first protective layer, a fiber layer and a second protective layer which are sequentially arranged from inside to outside, and the plurality of wire core units are distributed at intervals in the circumferential direction of the force bearing unit; and a first waterproof layer is filled between the first protective layer and the force bearing unit, and the first waterproof layer is fixedly connected with the first protective layer. The marine towing cable provided by the invention is relatively good in waterproof performance.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a marine streamer. Background technique [0002] Marine streamers are often used to explore the seabed to collect information such as seismic sources and energy distribution on the seabed. [0003] The marine streamer includes a cladding layer, a protective layer and a bearing layer which are usually provided with a plurality of core units and surrounding the plurality of electric core units. The gap in the wrapping layer is also filled with a water blocking layer to avoid water seepage of the core unit. The wrapping layer is surrounded by the water blocking layer, which can make the water blocking layer more round. In the protective layer, the marine streamer has better tear resistance. The bearing layer is a steel wire armor layer, which is used to withstand the tensile torsion of the marine streamer. [0004] However, the wrapping layer is easily separated from the protecti...
