The utility model discloses a submarine cable protection device which aims at solving the problem that a submarine cable outer protective layer is rubbed by a steel protective pipe head.
The guide frame comprises a longitudinal beam, a first cross beam, a second cross beam, a first connecting plate and a guide tile, wherein the first cross beam and the second cross beam are connected with the longitudinal beam.
The locking device comprises a holding component and a lifting lug bolt.
The roller set comprises a transverse roller and two longitudinal rollers which are respectively connected with the longitudinal beams.
The first connecting plate is connected with the longitudinal beam, the first cross beam and the second cross beam.
And the first connecting plate is provided with a threaded hole matched with the lifting lug bolt.
The guide tile is a section of arc-shaped steel plate, and the radius of the arc is the same as that of the steel protection pipe.
The guide tile is connected with the first cross beam through a second connecting plate and is in butt joint with the second cross beam.
The enclasping component comprises a locking plate, a third connecting plate and a fourth connecting plate.
The locking plate is a section of arc-shaped steel plate, and the radius of the arc is the same as that of the steel protection tube.
And the inner side of the locking plate is stuck with a rubber plate.
And the third connecting plate is provided with a bolt hole matched with the lifting lug bolt.
The lifting lug bolt penetrates through the bolt hole in the third connecting plate and is screwed into the threaded hole in the first connecting plate.
The beneficial effects of the utility model are as follows: the submarine cable protection device suitable for being installed on the underwater protective pipe head is light in structure and rapid in underwater installation, and the problem of friction between the protective pipe head and the submarine cable outer protective layer is effectively solved.

Detailed Description
Taking the example that the 220kV submarine cable 1 passes through a dyke, the diameter of the 220kV submarine cable 1 is 250mm, and the protective tube 2 is a phi 610 multiplied by 40mm steel tube.
Referring to fig. 1, 2 and 3, a submarine cable protection device comprises a guide frame 3, a locking device 4 and a roller set 5.
The guide frame 3 comprises four longitudinal beams 31, four first cross beams 32 and four second cross beams 33, a first connecting plate 34, guide shoes 35. The longitudinal beam 31 is a square steel pipe 100X 5mm; the first beam 32 is made of square steel tubes 50×50×4mm; the second beam 33 is a square steel pipe of 100×100×5mm. The guide shoe 35 is a section of arc plate made of a steel plate with the thickness of 350 multiplied by 5mm, and the radius of the arc is phi 305mm; is connected with the first beam 32 through a second connecting plate 36 and is butted with the second beam 33. The first connecting plate 34 is made of a steel plate with the thickness of 200 multiplied by 75 multiplied by 5mm, threaded holes matched with lifting lug bolts are formed in the steel plate, and the perforated holes are thickened to 15mm partially.
The roller set 5 comprises a transverse roller 51 and two longitudinal rollers 52 which are respectively connected with the longitudinal beams 31, and the diameters of the rollers are phi 90mm.
