The cylinder body is a convex cylinder body with two ends being internally contracted and the middle being outwards protruded. The utility model ensures the stable and reliable transportation of the floating pipe and prolongs the service life of the whole floating pipe.

Description

Water floating pipe

Technical Field

The utility model relates to the technical field of pipeline manufacturing, in particular to an improvement on a water floating pipe structure.

Background

In marine oil transportation and mud discharge operations, a floating pipe is often used, namely, a pipeline floats on the water surface for transportation operation. In the prior art, a technical form of adopting a hose and an external buoy is available. However, under the working condition of large flow operation, a conveying pipeline with a larger caliber is needed, and the difficulty of installing the buoy outside the conveying pipeline is higher. Therefore, a pipeline which can float on the sea surface and meet the requirement of large-flow conveying is urgently needed to be designed.

SUMMERY OF THE UTILITY MODEL

The utility model aims at the problems and provides the water floating pipe which has buoyancy and can keep stable under the conditions of tide and local surge.

The technical scheme of the utility model is as follows:

the water floating pipe comprises a pipe body, two ends of the pipe body are respectively and fixedly provided with a connecting flange,

the outer portion of the pipe body is provided with a pair of ring plates, and a cylinder body is fixedly connected between the pair of ring plates, so that a gap is formed between the inner wall of the cylinder body and the outer wall of the pipe body.

And a plurality of fixed rib plates are arranged on the outer sides of the ring plates.

At least one pair of fin plates are detachably arranged on the fixed rib plates which are symmetrical at the lower part of the tube body.

The fin plate and the central line of the tube body in the vertical direction form an included angle of 45-90 degrees.

The cylinder body is a convex cylinder body with two ends being internally contracted and the middle being outwards protruded.

According to the water floating pipe, the buoyancy of the floating pipe is increased by arranging the annular plate-cylinder-pipe body outside the pipe body to form the cavity layer enclosed by the pipe body, so that the floating pipe can bear large-flow conveying. On the other hand, the fin plate is arranged at the lower part of the pipe body to form a fin bionic structure, so that when tide/surge transversely impacts the floating pipe, the fin plate downwards slaps the water body to form reverse impedance, torsion of the pipe body caused by impact is reduced, and torque borne by the connecting flange is reduced, so that stable and reliable conveying of the floating pipe is ensured, and the service life of the whole floating pipe is prolonged.

fig. 2 is a sectional view a-a in fig. 1.

FIG. 1 shows a tubular body; 2 is a cylinder, 21 is a gap; 3 is a ring plate, 31 is a fixed rib plate; 4 is a connecting flange; 5 is a fin.

Detailed Description

The utility model is further described below with reference to FIGS. 1-2.

The water floating pipe comprises pipe bodies 1, wherein connecting flanges 4 are fixedly arranged at two ends of each pipe body 1 respectively, and a plurality of pipe bodies 1 are connected in series through the connecting flanges 4 to form a conveying pipeline;

a pair of ring plates 3 are arranged outside the pipe body 1, and the cylinder body 2 is fixedly connected between the ring plates 3, so that a gap 21 is formed between the inner wall of the cylinder body 2 and the outer wall of the pipe body 1, and the gap 21 is used for increasing the buoyancy of the pipe body 1.

A plurality of fixing rib plates 31 are arranged on the outer side of the ring plate 3 and used for reinforcing the ring plate 3.

The fixed ribbed slab 31 of the lower part symmetry of body 1 is gone up to dismantle and is provided with at least a pair of fin 5, and fin 5 is connected in the side of fixed ribbed slab 31, and fin 5 of symmetry forms the bionic molding of fin for when floating the pipe and having met horizontal rivers, can reduce the rotation moment of torsion of body, the reliability of the connecting piece of protection flange 4. The fin plate 5 is additionally arranged on the pipe body 1 in the water area section with complicated ocean currents and complicated ocean surface undercurrents by using the fixed rib plate 31 as a carrier for additionally arranging the fin plate 5, so that the pipe body 1 can be prevented from rotating under the action of transverse water flow, and the torque borne by the flange part when the multi-section pipe body 1 is connected is reduced.

The fin plates 5 form an included angle of 45-90 degrees with the central line of the tube body 1 in the vertical direction.

The cylinder body 2 is a convex-belly cylinder body with two ends being internally contracted and the middle being outwards protruded, so that even if the floating pipe is damaged by natural or artificial pounding, the gap 21 is shrunken and attached to the pipe body 1, the convex-belly section of the cylinder body 2 can still enable the floating pipe to keep basic buoyancy level, and the pipeline is prevented from sinking.
