Description

Pipeline protection sleeve

The invention relates to a protection technology, in particular to a pipeline protection cover for pipeline protection.

Wired communication is transmitted in a point-to-point manner, usually using a pipeline configuration connection. In the case of optical cables, optical cables refer to a certain number of optical fiber wires that form a cable core in a certain way. Because the optical fiber wires themselves are relatively fragile and easy to break, if they are in direct contact with the outside world, they are prone to scars or even broken. The outer layer of the optical fiber is coated with a protective sheath.

The setting of the protective cover can prevent water vapor intrusion and other external environmental damage, such as fire, weathering or gnawing by squirrels or birds and wild animals. At present, most of the protective sleeves are made of natural rubber, but the smell of natural rubber is easy to attract squirrels, which leads to a serious situation of optical cables being bitten by squirrels.

At present, although some operators have changed the protective cover of the optical cable to a design such as a steel mesh cable or a glass fiber coated cable, which can prevent wild animals from biting, but it has caused a substantial increase in the cost of cable deployment, which is not in line with benefits.

In view of this, the present invention proposes a pipeline protective cover to effectively overcome the above-mentioned problems.

Another object of the present invention is to provide a protective cover for pipelines, the metal layer of which can improve the protection against lightning strike line surge (Line surge), and quickly transmit the surge to the grounding point to release to the ground.

To achieve the above-mentioned purpose, the present invention provides a pipeline protective sleeve, which can be wound and cemented to wrap around a pipeline to protect the pipeline. The pipeline protective cover includes a protective layer wrapped around the outer layer of the pipeline, and the protective layer is further coated with a metal layer.

In this embodiment, the protective layer is an artificial rubber layer.

In this embodiment, the artificial rubber layer is a butyl rubber layer or a semi-cured industrial rubber layer.

In this embodiment, the protective layer is a reactive powder concrete (Reactive Powder Concrete, RPC) layer.

In this embodiment, the protection layer is a composite protection layer composed of any at least one of butyl rubber and cementitious material, and at least one of corundum sand and steel fiber.

In this embodiment, the corundum is silicon carbide (SiC); the cementing material is semi-cured artificial rubber or reactive powder concrete (Reactive Powder Concrete, RPC).

In this embodiment, the metal layer is an aluminum layer.

In this embodiment, the pipeline protective cover further includes a fiber layer wrapped between the metal layer and the protective layer.

In this embodiment, the fiber layer is a non-woven fabric layer or a metal fiber layer.

In this embodiment, the metal fiber layer is a copper fiber layer or a steel fiber layer, or a composite fiber layer composed of copper fiber materials and steel fiber materials.

In this embodiment, the pipeline protection sleeve further includes an isolation film covering the metal layer.

In this embodiment, the isolation film is a plastic isolation film.

In this embodiment, the plastic isolation film is a chlorinated polyvinyl chloride (CPVC) isolation film or a polyethylene (PE) isolation film.

The optical cable includes a plurality of optical fiber lines 20 , a cable core 22 and a sleeve 24 . The optical fiber line 20 is used to provide optical fiber network information. The sleeve 24 is used to cover the plurality of optical fiber wires 20 , and the center of the plurality of optical fiber wires 20 is provided with a cable core 22 .

As shown in the figure, the pipeline protective cover 1 includes a protective layer 10 and a metal layer 12 . The protective layer 10 covers the outer layer of the pipeline 2 , and the metal layer 12 covers the outer layer of the protective layer 10 .

Protective layer 10 can be active powder concrete (Reactive Powder Concrete, RPC) layer or artificial rubber layer, because artificial rubber belongs to wild animals, such as squirrels, birds and other disgusting tastes, so the setting of protective layer 10 is preferably artificial rubber layer. Embodiment, can prevent wild animals from biting. Wherein the artificial rubber can be butyl rubber or a semi-cured industrial rubber layer, and the best embodiment is a butyl rubber layer. Because butyl rubber has permanent non-curing properties, the setting of the protective layer 10 can maintain permanent flexibility, so that the pipeline 2 It has a high degree of displacement tolerance, excellent waterproof sealing and chemical corrosion resistance, can effectively resist ultraviolet rays (sunshine), and has heat and weather resistance. It can provide good protection whether it is a typhoon or a fire. In addition, butyl rubber has a strong adhesive force on the surface of various materials, and has the advantages of sealing, shock absorption, and protection on the surface of the adherend, so butyl rubber is very suitable as a coating on the pipeline 2 The outer layer can improve the service life of the pipeline 2 for more than 20 to 30 years.
