Detailed Description
In order to clearly understand the technical features, objects, and effects of the present invention, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
As shown in fig. 1, the composite material protective cover for an underwater umbilical of the present invention includes at least one protection unit 1 for covering the underwater umbilical to protect the underwater umbilical.
The protection unit 1 includes a protection cover main body 10, a first connection cover 20 connected to one end of the protection cover main body 10, and a second connection cover 30 connected to the opposite end of the protection cover main body 10. The protective cover body 10 is used for covering the underwater pipe cable and extending along the axial direction of the underwater pipe cable, and the length can be set according to the requirement. The cross section of the protective cover body 10 corresponding to the underwater umbilical can be fitted on the outer surface of the underwater umbilical in an arc shape. The first and second coupling caps 20 and 30 are each arched, such as a hemisphere, and have a corresponding inner diameter larger than that of the protective cap body 10. The first connecting cover 20 and the second connecting cover 30 are arranged in a matching manner, and the inner diameter of the first connecting cover 20 is larger than that of the second connecting cover 30, so that the first connecting cover 20 can be movably matched on the second connecting cover 30 of another protecting unit 1 to movably connect the two protecting units 1, and the two connected protecting units 1 can rotate relatively.
Wherein, the surface of the protective cover main body 10 is provided with at least one lifting lug 11 for connecting a lifting appliance, lifting the whole protective unit 1, and facilitating the lifting on land and on the sea. Preferably, the four opposite corners of the protection cover main body 10 are respectively provided with lifting lugs 11, so that the whole protection unit 1 can be stably lifted. Of course, the lifting lugs 11 are not limited to four or four diagonal positions, and can be increased or decreased according to the offshore lifting environment (influenced by wind, wave, ship motion and the like), the required lifting force and the like. The hanging lug 11 may be a hole formed through the protective cover body 10, a hanging ring structure formed on the protective cover body 10, or the like.
The first and second connection caps 20 and 30 are connected to both ends of the protection cap body 10, respectively, to be integrated therewith. The mating surfaces of the first and second connection caps 20 and 30 are smooth to allow relative movement after mating.
The utility model discloses in, protection unit 1 adopts combined material to make, and combined material plasticity and machinability are strong, and the shapable is various required structures. The composite material may be, but is not limited to, a carbon fiber composite material or a glass fiber reinforced composite material. Compared with steel materials, the protection unit 1 made of the composite material has the advantages of light weight, high strength, tight protection, smooth surface, corrosion resistance, impact resistance and the like, and is convenient to hoist and transport. Preferably, the protection unit 1 is made of a composite material by a vacuum introduction process, and has a smooth surface and good quality.
Further, the protection unit 1 further includes sinking prevention plates 40 connected to axially opposite sides of the protection cover main body 10. The anti-sinking plate 40 increases the contact area between the protection unit 1 and the seabed, and prevents the protection unit 1 from sinking after being placed on the seabed. The anti-sinking plate 40 is also made of a composite material, and can be integrally formed with the protection cover main body 10, the first connection cover 20 and the second connection cover 30 to form the protection unit 1 of an integrated structure.
Both ends of the anti-sink plate 40 at each side of the protective cover main body 10 are extended and connected with the sides of the first and second connection covers 20 and 30, respectively, so that the anti-sink plates 40 are provided at opposite sides of the whole protective unit 1.
The anti-sink plates 40 of each of the opposite sides of the protection unit 1 may be distributed along the length of the protection unit 1 as a whole or may be distributed locally.
In addition, because the protection unit 1 hoists over the sea surface and is influenced by wave attack force, the phenomenon that a lifting rope is loosened is easily generated, and the counterweight 50 needs to be arranged on the protection unit, so that the temporary positioning effect is realized. In this regard, the composite material protective cover further comprises a counterweight 50, which ensures that the protective unit 1 is not displaced by the sea currents in a short time. As shown in fig. 1, in the present embodiment, the balance weight 50 is provided on the anti-settling plate 40. The weight 50 may be one or more, and is distributed on one side or opposite sides of the protective cover body 10. The counterweight 50 can be fixed on the anti-sinking plate 40 through bolts, and is convenient to disassemble and assemble.
After the protection unit 1 is covered on the underwater pipe cable and is arranged on the seabed, in order to enhance the stability of the protection unit 1 on the seabed, weights such as cement pressing blocks or falling rocks can be arranged on the anti-sinking plate 40 to prevent the protection unit 1 from shifting after being influenced by ocean currents.
In general, the underwater cable needs a long protection part, and two or more protection units 1 need to be covered thereon. Thus, as shown in fig. 2, the composite material protective cover of the submarine umbilical preferably comprises at least two protection units 1. Wherein, the first connecting cover 20 of one protecting unit 1 is matched on the second connecting cover 30 of the other protecting unit 1 to movably connect the two protecting units 1.
The first connection cover 20 and the second connection cover 30 can be respectively provided for a hemispherical shell, and the cooperation of the two connection covers enables the two protection units 1 to effectively cooperate with each other and play a role of mutual locking. The cooperation of the first and second coupling caps 20 and 30 functions as a ball joint.
On the underwater pipe cable, when the underwater pipe cable is influenced by temperature or external force to move, two adjacent protection units 1 can move or rotate relatively along with the underwater pipe cable, so that the protection failure of the underwater pipe cable is avoided.
The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all the equivalent structures or equivalent processes that are used in the specification and the attached drawings or directly or indirectly applied to other related technical fields are included in the patent protection scope of the present invention.
