Abstract
The invention relates to a water surface cable which has an electric energy transmission function, can float on the water surface, has good flexibility and can be subjected to take-up and pay-off repeatedly, in particular to a flexible positive buoyancy cable floating on the water surface. The flexible positive buoyancy cable is suitable for supplying power to operation vessels on the water surface, floating operation platforms, water surface detection equipment and others. The cable can be subjected to take-up conveniently, can be used repeatedly and can also serve as a warning mark and an insulating strip in water. The cable comprises an enhancement type foamed plastic floating body, a water retarding buffering layer, multiple strands of multiple stranded flexible cable water retarding conductors, a light type cable insulating layer, a tensile enhancement layer and an outer protection layer. The enhancement type foamed plastic floating body is arranged in the center of the cable, the water retarding buffering layer is arranged outside the enhancement type foamed plastic floating body, the strands of multiple stranded flexible cable water retarding conductors are arranged outside the water retarding buffering layer, the light type cable insulating layer is arranged outside the strands of multiple stranded flexible cable water retarding conductors, the tensile enhancement layer is arranged outside the light type cable insulating layer, and the outer protection layer is arranged outside the tensile enhancement layer.
Description
Technical field
The flexible positive buoyancy floating on water of the present invention cable relates to is a kind ofly to have delivery of electrical energy function, can swim on the water surface and have good flexibility, repeatedly the water surface cable of folding and unfolding.Applicable to power supplies such as operation ship, floating job platform, water surface detecting devicess on the water surface; The type cable reclaims convenient, can repeatedly use, and also can be used as warning mark and isolation strip in water.
Background technology
In recent years, continuous enhancing along with China's ocean development dynamics, be used to the fixedly on-fixed cable of marine exploration equipment, maritime floating platform, the power supply of water surface floating ship more and more to be applied, this invention product is exactly the floating on water service cable that is applied to above place and equipment.
Summary of the invention
