Description

Screw penetration type recyclable marine anchor anchoring system and application method thereof

Technical Field

The invention relates to the technical field of ocean and ship engineering, in particular to a spiral penetrating type recyclable marine anchor anchoring system and a using method thereof.

Background

The number of times of anchoring of the vessel in the anchor ground of the offshore area, including the phenomenon of emergency anchoring and temporary berthing of the vessel in the non-anchor ground, is also increasing, and the occurrence frequency of the vessel anchoring is increased comprehensively. In recent years, marine vessel anchoring in offshore areas has become an important factor affecting the safe operation of subsea pipelines. The anchor phenomenon of the ship can cause irreparable damage to the submarine pipeline, and the frequent surge of the anchor phenomenon can cause huge economic and social benefit loss.

Existing marine anchors can be generally classified into a rod-type anchor and a rodless anchor, the rod-type anchor also being called a naval anchor; the rodless anchors are also called mountain anchors, and can be further subdivided into common rodless anchors and large-grasping anchors. The common rodless anchors commonly used at the present stage are Hall anchors and Stokes anchors; whereas the typical high grip anchors are mainly AC-14 type high grip anchors and bolter anchors.

However, vessels are usually subjected to both the landing and towing processes, whether they are anchored using existing, or rodless, anchors. The anchor dropping operation means that a ship starts an anchor machine, so that the ship anchor drops to the seabed mud surface under the action of gravity; the towing anchor operation refers to the process that the ship anchor continuously moves on the seabed under the towing action of the towing ship, and the fluke is continuously meshed with the bottom soil, so that the anchor pulling force is increased, and the ship is braked or the rotation of the bow is controlled. It can be found that the anchor dropping and the anchor pulling operation of the ship can cause anchor damage, especially the anchor pulling process, the influence range is wide, the operation length is long, and the possibility of causing anchor damage to the submarine pipeline is higher.

In order to avoid the anchor damage phenomenon, the influence range and depth in the process of anchoring the ship anchor can be reduced, or the distance of the anchor is reduced as much as possible, and even the anchor operation is cancelled. The latter of which can solve the problem of the anchor damage of the ship anchor from a more fundamental level, and should cut into the problem from this point of view.

Chinese patent CN113928477a discloses a gravity penetration type deep water anchor and construction method, which is characterized in that the anchor body penetrates into the soil body of the seabed by gravity, after the penetration is completed, the supporting plate and the geomembrane are opened, and grouting is performed between the supporting plate, the geomembrane and the anchor body through grouting pipes to form grouting consolidation blocks, thereby realizing the whole anchoring effect. Chinese patent CN113734357B discloses a spin-penetration type suction anchor foundation and a penetration method for anchoring a floating type marine structure, which are characterized in that a suction pump is utilized to pump a closed water body in the anchor body, a pressure difference is formed in the anchor body, and the anchor body is matched with the self rotation of the anchor body to form downward penetration force until a top cover of the anchor body is completely contacted with a soil body, so that the anchor body is installed, and an anchoring effect is formed by the contact of the anchor body and the soil body of a seabed.

The vertical penetrating anchors commonly used at present are mostly permanent anchoring systems, and the anchoring force is generated by completing installation through gravity, grouting or suction and rotation. The anchoring force structure is formed by gravity and grouting, the anchor body is basically restrained below the seabed soil body, and the possibility of recovery does not exist. The anchor body is difficult to recover by simply relying on reverse rotation due to the existence of the suction force and the rotation, and the recovery is completed in a mode of injecting high-pressure water or gas, so that the recovery difficulty is high, the recovery time is long, and the flexibility of the ship is insufficient; the installation difficulty of the suction installation is relatively high, the preparation work is complex, the emergency anchoring of the ship is not facilitated, and a certain danger is brought to the ship; meanwhile, high requirements are also put forward on the structural strength of the anchor body by long-time and multi-frequency water pumping operation, so that the manufacturing cost of the anchor body is too high, and commercial application is difficult to realize.

The steel strand 16 is arranged inside the steel round tube 12, the upper end of the steel strand is connected with the telescopic extension rod driving motor 21, and the lower end of the steel strand is connected with the penetration rod 6. When the telescopic extension rod driving motor 21 works, the telescopic extension rod can be lengthened or shortened through the internal steel strands 16, so that the screw penetration type recyclable marine anchor system is anchored or recycled, and the marine anchor system is convenient to store.

The radius of the steel tube 12 gradually decreases from bottom to top. The radius of the bottommost steel tube 12 is maximized to ensure that it has sufficient resistance to overturning moment and shear forces. The radius of the steel round tube 12 at the very top is minimal, but it should be ensured that at least two steel strands 16 and one steel-wire-containing hose 11 can pass (see example 2 for a specific construction). As shown in fig. 5, the outer wall of the proximal end portion of each steel round tube 12 is provided with a separation preventing and limiting protrusion 15, so that the separation preventing and limiting protrusions 15 of two adjacent steel round tubes 12 are mutually clamped and connected, and the steel round tubes 12 are prevented from separating from each other in the telescoping process of the telescoping extension assembly 3, so that a use accident occurs. As shown in fig. 4, an anti-torsion limit groove 13 is formed on the inner wall of each steel round tube 12; an anti-torsion limiting protrusion 14 is arranged on the outer wall of the corresponding position; the anti-torsion limiting protrusion 14 extends into the anti-torsion limiting groove 13, so that two adjacent steel round tubes 12 are axially fixed, and torque load can be transmitted to the spiral penetrating component 1 below through the telescopic extension rod when the telescopic extension rod rotates.

The buoy assembly 5, as shown in fig. 8, includes a buoy 22, a buoy link 23, a mast 24, and a lighting device 25. The middle part of the floating body 22 is provided with a hole, the radius of the hole is larger than that of the top steel round pipe 12 and smaller than that of the winch 17, so that the steel round pipe 12 can pass through but not higher than the winch 17, and the floating body is lost. The buoy link 23 is rigidly connected to the buoy 22; the mast 24 is rigidly connected above the buoy link 23; the lighting device 25 is rigidly connected to the top of the mast 24. The float 22, float link 23, mast 24 and lighting 25 are all painted a more vivid color.

Example 2

This embodiment is based on embodiment 1, and its preferred or additional structure is described.

Before the anchoring system is installed, seawater is injected into the penetrating rod 6 through the steel wire-containing hose 11 by a water pump, so that the weight of the anchoring system is increased; when the anchoring system is dismantled, the seawater in the penetrating rod 6 is pumped out by the water pump through the steel wire-containing hose 11, so that a cavity is formed in the penetrating rod 6, thereby generating buoyancy and facilitating the dismantling of the anchoring system.

The screw penetration type recoverable marine anchor anchoring system further comprises an anchor chain link assembly 2; the anchor chain link assembly 2 comprises a link sleeve 9, two link sleeve limiting pieces 8 and a marine anchor chain; the linking sleeve limiting piece 8 and the linking sleeve 9 are both round, and the radius of the linking sleeve limiting piece 8 is slightly larger than that of the linking sleeve 9. The two connecting sleeve limiting parts 8 are rigidly sleeved and connected to the penetration rod 6; the link sleeve 9 is placed between the two link sleeve stoppers 8, and the link sleeve 9 is sleeved on the penetration rod 6 without contact. The linking sleeve 9 is provided with a connecting element, such as a shackle, which can be linked to a marine anchor chain. The linking sleeve 9 is directly linked to the marine anchor chain via a connection, which is directly linked to the anchor chain winch of the vessel. After the spiral penetration assembly 1 completely penetrates into the soil body, the ship load transmitted by the ship anchor chain can be further transmitted to the penetration rod 6, and then the penetration rod 6 and the spiral blades 7 are transmitted to the seabed soil body, so that sufficient anchoring force can be provided for the ship when the spiral penetration assembly 1 completely penetrates into the soil body, and the ship can be kept relatively stable under the action of the wind and wave load under the berthing condition.

As shown in fig. 6 and 7, a linking groove 19 is formed on the outer wall of the top steel round tube 12, one end of a detachable linking rod 20 is fixed on the hull, and the other end is clamped in the linking groove 19, so that the whole anchoring system is fixed. When the anchoring system is penetrated or accommodated in the hull, the detachable linking rod 20 should clamp the linking groove 19 to fix the whole anchoring system, and the transmission member 18 should be fully linked with the winch 17; when the anchoring system is in an anchoring working state, the disengageable linking rod 20 is disengaged from the linking groove 19, the transmission member 18 is disengaged from the winch 17, and the vessel is linked with the anchoring system only by the marine anchor chain.

Example 3

After the system is stable, the driving motor is started, and forward torque is transmitted to the spiral penetration assembly 1 through the transmission piece 18, the winch 17 and the telescopic extension rod; the helical blades 7 penetrate downwards under the action of the forward torque until the helical penetration assembly 1 completely penetrates into the seabed soil body, so that enough anchoring force is provided for the ship, and the anchoring operation is completed. If the anchoring force provided by the single anchoring system is insufficient, two anchoring systems can be matched with the ship, so that the displacement of the ship under the action of wind and wave load is better limited, and the berthing safety of the ship is ensured.

When the ship needs to be anchored and sailed, the ship finds out the corresponding position through the buoy assembly 5;

the detachable connecting rod 20 is clamped with the connecting groove 19, so that the ship and the anchoring system form stable interaction, and then the steel wire-containing hose 11 is connected with a water pump on the ship; the transmission member 18 is tied to the winch 17, and then the water pump is started to pump seawater penetrating into the rod 6.
