Description

Technical Field

[0001] This invention belongs to the field of deep-sea mooring technology, and particularly relates to a marine anchoring device and its deployment method. Background Technology

[0002] Current anchoring methods require specialized installation vessels equipped with anchoring equipment to drop anchors and release anchor chains to complete the installation of mooring anchors. This traditional method carries a high risk of human intervention, with potential for inaccurate dropping, leading to swaying and anchor dragging. Furthermore, the dropping speed must be manually controlled, resulting in close proximity between the anchor and the installation vessel during the process, increasing the risk of collisions and other safety accidents. In short, mooring anchor installation is difficult.

[0003] Furthermore, existing technologies mostly optimize the mooring process by designing specific deployment devices on the installation vessel. However, for the installation of large deep-sea anchor piles, it is difficult to find an installation vessel with a suitable tonnage to carry such anchor piles, which significantly increases the difficulty of installing deep-sea anchor piles.

The rotating shaft is fixedly connected to the movable ring of the inner ring of the bearing.

[0012] Furthermore, it also includes a ballast water assembly installed on the platform and working in conjunction with the support column to adjust the platform's draft. The support column has a water storage chamber inside. The ballast water assembly includes a water tank fixedly installed on the platform and a bidirectional water pump installed on the platform. The water pipes at both ends of the bidirectional water pump are respectively connected to the water storage chamber and the water tank of the support column.

[0038] The technical solution of the present invention will be further described below with reference to the accompanying drawings.

[0039] Example 1

[0040] This invention discloses a marine anchoring device, such as... Figure 1 As shown, the platform includes a mounting component 1, a support column 2, a float 3, a lifting device 4, a control component, a ballast water component 6, an anchor storage component 7, and a chain storage compartment 8. Multiple mounting components 1 are assembled to form a closed-loop platform, with the central space used for anchor deployment. The support column 2 is fixedly installed at the bottom of the platform, and the float 3 is fixedly installed at the bottom of the support column 2, allowing the platform to float on the water surface. The float 3 is disc-shaped. The lifting device 4 is installed on the platform and used to lift and deploy anchors. The control component is installed on the platform and used to control the anchor chain. The ballast water component 6 is installed on the platform and works with the support column 2 to adjust the platform's draft. The anchor storage component 7 is installed on the platform and used to store anchors to be deployed. The lifting device 4 works with the anchor storage component 7 to lift, replace, and deploy different types of anchors. The chain storage compartment 8 is installed on the platform and is used to store and assist in the deployment and retrieval of anchor chains. Before anchoring, the anchor is stored in the anchor storage assembly 7 and the anchor chain is stored in the chain storage compartment 8. Before anchoring, the anchor to be deployed is taken out of the anchor storage assembly 7 and lifted by the lifting equipment 4. After the anchor chain is taken out of the chain storage compartment 8, one end of the anchor chain is connected to the anchor to be deployed in the platform ring, and the other end of the anchor chain is passed through the control assembly and connected to the mooring mechanism outside the platform. During the anchoring process, the control assembly is used for the anchor chain.

[0041] Preferably, the platform is equipped with a domestic water tank 9 for storing domestic water, which is convenient for staff to use during offshore operations.

[0042] like Figure 1 and Figure 2As shown, the mounting component 1 includes a load-bearing body 11, a connecting frame 12, a working platform 13, a guardrail 14, and a connecting plate 15. The connecting frame 12 is fixedly installed on the outer periphery of the load-bearing body 11, and the working platform 13 is fixedly connected to the top of the load-bearing body 11. The working platform 13 serves as the working surface for the workers. The guardrail 14 is fixedly installed on the top of the working platform 13 and provides corresponding protective measures for the workers during anchoring. The connecting plate 15 is fixedly connected to the top of the connecting frame 12. When mounting the platform, the connecting plates 15 of the two mounting components 1 are connected by bolts. During actual anchoring, the quantity and size of the mounting components 1 can be selected according to the specifications of the anchor to be deployed, the operating sea environment, and other requirements. That is, the platform of the required size can be spliced ​​and assembled according to the needs, without relying on a specific tonnage of the installation vessel. The overall practicality and applicability are strong. It effectively solves the problem of poor adaptability of deep-sea large anchor pile installation and expands the adaptability range for different types of anchor bodies such as irregular anchors and dynamic anchors. Preferably, the load-bearing body 11 is configured as a cylindrical structure, and the load-bearing bodies 11 of two adjacent sets of mounting components 1 are connected by flanges. The cylindrical structure can reduce the weight of the mounting components 1. Preferably, multiple reinforcing rods 17 arranged in a triangular pattern are fixedly connected to the connecting frame 12, which helps to improve the structural stability of the connecting frame 12.

[0043] like Figure 1 , Figures 3 to 7 As shown, the control assembly includes a sleeve 5, a conveyor, a chain stopper, and a release member. The sleeve 5 is fixedly installed on the outer periphery of one of the mounting components 1, and the sleeve 5 is provided with a channel 10 for the anchor chain to extend from inside the platform ring to outside the platform ring. The inlet 101 of the channel 10 is located inside the platform ring, and the outlet 102 of the channel 10 is located outside the platform ring. The conveyor is installed on the sleeve 5 and conveys the anchor chain along the channel 10. The chain stopper is provided on the sleeve 5 and is used to limit the anchor chain when the conveying of the anchor chain stops. The release member is provided on the sleeve 5 and cooperates with the chain stopper to release the anchor chain from the sleeve 5.

[0044] like Figures 3 to 6As shown, the conveying component includes a first motor 51, a power shaft 52, a rotating disk 53, a first transmission shaft 54, a first transmission belt 55, and grippers 56. The first motor 51 is fixedly installed on the top of the sleeve 5. The power shaft 52 is fixedly connected to the output shaft of the first motor 51. Two rotating disks 53 are provided, and the two rotating disks 53 are symmetrically arranged and rotatably installed in the channel 10. The first transmission shaft 54 ​​is fixedly connected between the two rotating disks 53. The first transmission belt 55 is installed on the outer periphery of one of the rotating disks 53 and the power shaft 52. Multiple grippers 56 are provided, and the multiple grippers 56 are distributed in a ring array and fixedly installed on the opposite sides of the two rotating disks 53. The anchor chain links are arranged in a cross pattern. When the anchor chain passes through the channel 10, the claws 56 on the two rotating disks 5 engage with the vertically distributed links on both sides of the anchor chain. After the first motor 51 is started, it drives the power shaft 52 to rotate. The power shaft 52 drives the rotating disks 53 to rotate synchronously through the first transmission shaft 54. When the two rotating disks 53 rotate, the claws 56 on the two rotating disks 5 hold the anchor chain and move it, thus realizing the anchor chain transport. Preferably, there are two sets of conveying components, located at the inlet 101 and outlet 102 of the channel 10, respectively. The cooperation of the two sets of conveying components not only improves the anchor chain transport efficiency but also effectively prevents the anchor chain from accumulating in the channel 10. The conveying components enable uniform speed transport of the anchor chain, which not only improves the stability of the anchor body during descent but also increases the efficiency of anchor deployment.

[0045] like Figure 4 As shown, the chain stopper includes a hydraulic telescopic rod 58 and a first braking block 59. A receiving cavity 57 is provided on the inner wall of the channel 10. The hydraulic telescopic rod 58 is fixedly installed in the receiving cavity 57. The first braking block 59 is fixedly connected to the output end of the hydraulic telescopic rod 58 and is used to engage the anchor chain to stop its transport. When transporting the anchor chain, the hydraulic telescopic rod 58 is controlled to retract the first braking block 59 into the receiving cavity 57 to prevent it from affecting the transport of the anchor chain. When it is necessary to stop transporting the anchor chain, the hydraulic telescopic rod 58 is controlled to extend the first braking block 59 into the channel 10 and engage the anchor chain.

[0046] like Figure 3 and Figure 4As shown, the release mechanism includes a first release plate 510, a first drive member, a second release plate 511, and a second drive member. The first release plate 510 is rotatably mounted on the bottom of the sleeve 5. The first drive member is mounted on the sleeve 5 and is used to drive the first release plate 510 to rotate. Two second release plates 511 are provided, rotatably mounted on the side of the sleeve 5. The two second release plates 511 are symmetrically mounted on both sides of the sleeve 5, that is, one second release plate 511 is located inside the platform ring, and the other second release plate 511 is located outside the platform ring. The second drive member is mounted on the sleeve 5 and is used to drive the second release plate 511 to rotate. A second braking block 512 that cooperates with the chain stopper is installed on the first release plate 510. The second braking block 512 and the first braking block 59 are symmetrically arranged. The hydraulic telescopic rod 58 extends the first braking block 59 into the channel 10 and locks the anchor chain between the first braking block 59 and the second braking block 512.

[0047] like Figures 3 to 5 , Figure 7 As shown, the first driving component includes a second motor 513, a first reversing gear 514, a connecting seat 515, a second drive shaft 516, a second reversing gear 517, a first connecting block 518, a rotating shaft 519, a second connecting block 520, a third reversing gear 521, and a fourth reversing gear 522. The second motor 513 is fixedly mounted on the top of the sleeve 5. The first reversing gear 514 is fixedly connected to the output shaft of the second motor 513. The connecting seat 515 is fixedly mounted on the side of the sleeve 5, and multiple connecting seats 515 are provided. The second drive shaft 516 is rotatably connected to the connecting seat 515 through a bearing. The second reversing gear 517 is fixedly mounted on the top of the second drive shaft 516, and the first reversing gear 518 is fixedly mounted on the top of the second drive shaft 519. The rotating shaft 519 is a rotating shaft 510, the second connecting block 520, the third reversing gear 521, and the fourth reversing gear 522. The second reversing gear 517 is meshed with the first reversing gear 514; multiple first connecting blocks 518 are provided, and the multiple first connecting blocks 518 are evenly distributed and fixedly installed at the bottom of the sleeve 5. The rotating shaft 519 passes through the multiple first connecting blocks 518 and is rotatably connected to them. The second connecting block 520 is fixedly connected between the rotating shaft 519 and the first release plate 510, and the first connecting block 518 and the second connecting block 520 do not affect the normal rotation of the rotating shaft 519. The third reversing gear 521 is fixedly installed at the bottom of the second transmission shaft 516, and the fourth reversing gear 522 is fixedly installed on the rotating shaft 519, and the third reversing gear 521 and the fourth reversing gear 522 are meshed with each other. The second motor 513 drives the second transmission shaft 516 through the first reversing gear 514 and the second reversing gear 517. The second transmission shaft 516 drives the third reversing gear 521 to rotate synchronously. The third reversing gear 521 drives the rotating shaft 519 to rotate through the fourth reversing gear 522, thereby causing the rotating shaft 519 to rotate and open the first release plate 510.

[0048] like Figure 3 and Figure 8 As shown, the second driving component includes a bracket 523, a third motor 524, a worm gear 525, a worm 526, a rotating shaft 527, and a bearing 528. The bracket 523 is fixedly installed on the top of the sleeve 5, the third motor 524 is fixedly installed on the bracket 523, the worm gear 525 is fixedly connected to the output shaft of the third motor 524, the worm 526 is meshed with the worm gear 525, the rotating shaft 527 is fixedly connected to one side of the second release plate 511, and the top of the rotating shaft 527 is fixedly connected to the worm 526. The retaining ring of the outer ring of the bearing 528 is fixedly installed on the sleeve 5. The second release plate 511 has a through hole that matches the bearing 528, and the rotating shaft 527 is fixedly connected to the rotating ring of the inner ring of the bearing 528. The third motor 524 drives the worm gear 525 to rotate. The worm gear 525 meshes with the worm 526, causing the worm gear 525 to drive the worm 526 to rotate. The rotating shaft 527 rotates synchronously with the worm 526, causing the rotating shaft 527 to drive the second release plate 511 to rotate and open.

[0049] like Figure 1 and Figure 9 As shown, the ballast water assembly 6 includes a water storage tank 61, a bidirectional water pump 62, and water pipes 63. The water storage tank 61 and the bidirectional water pump 62 are fixedly installed on the platform. A water storage chamber is provided inside the support column 2. The water pipes 63 at both ends of the bidirectional water pump 62 are connected to the water storage chamber of the support column 2 and the water storage tank 61, respectively. Preferably, two sets of ballast water assemblies 6 are provided, and the two sets of ballast water assemblies 6 are symmetrically arranged on the platform to keep the platform in a balanced state. Each water storage tank 61 is connected to two support columns 2 through the bidirectional water pump 62 and water pipes 63. In actual use, a diverter is installed on the water storage tank 61 so that one bidirectional water pump 62 can control the water level in the water storage chambers of the two support columns 2. When it is necessary to reduce the platform's draft, water is pumped from the support column 2 to the water storage tank 61 via the bidirectional water pump 62. When it is necessary to increase the platform's draft, water is pumped from the water storage tank 61 to the support column 2 via the bidirectional water pump 62. The draft adjustment in a single operation is positively correlated with the amount of water pumped. The ballast water assembly 6 allows the entire device to resist wind and wave loads by adjusting the draft, effectively reducing the impact of wave disturbances on the platform. Furthermore, the ballast water assembly 6 can precisely control the platform's draft and buoyancy, enabling the platform to achieve the optimal mooring state that combines wave resistance and operational convenience in the wind and wave environment of the target sea area.

[0050] like Figure 10 and Figure 11As shown, the anchor storage assembly 7 includes a dynamic anchor box 71 and a non-dynamic anchor box 72. The dynamic anchor box 71 is used to store and fix the dynamic anchor, and the non-dynamic anchor box 72 is used to store the non-dynamic anchor. A hydraulic cylinder 73 is fixedly connected inside the power anchor box 71. The output end of the hydraulic cylinder 73 is fixedly connected to a first support frame 74 for supporting the power anchor. The power anchor box 71 is equipped with rails 714 symmetrically arranged on both sides of the first support frame 74. A sliding sleeve 75 is slidably connected to the rails 714, and a knob is threadedly connected to the sliding sleeve 75 to fix it at a designated position on the rails 714. A limit box 76 is fixedly connected to the sliding sleeve 75. A push plate 77 is slidably installed inside the limit box 76. A limit claw 78 is slidably connected to the limit box 76, with one end extending to the side of the limit box 76 facing the hydraulic cylinder 73. A spring 79 is fixedly connected between the limit claw 78 and the push plate 77. A threaded rod 710 for driving the push plate 77 to move is threadedly connected to the other side of the limit box 76. The spring 79 allows the limit claw 78 to fit against the outside of the anchor body and can be used for anchors of different shapes and models. Preferably, rubber pads are installed on both the first support frame 74 and the limiting claw 78, which helps to protect the anchor. Preferably, a third clamping block for supporting the head of the dynamic anchor is fixedly connected to the dynamic anchor box 71, and a fourth clamping block 715 that cooperates to fix the head of the dynamic anchor is engaged with the third clamping block.

[0051] When fixing the anchor, the power anchor is placed on the third clamping block. The first support frame 74 is controlled by the hydraulic cylinder 73 to support and lock onto the anchor body, achieving initial fixing. The fourth clamping block 715 is then clamped onto the third clamping block. The sliding sleeve 75 and the limiting box 76 are then moved along the track 714 to a suitable position on the side of the anchor body. The sliding sleeve 75 is then fixed in the current position. The threaded rod 710 is then rotated to move the push plate 77 toward the anchor. The push plate 77, through the spring 79, drives the limiting claws 78 toward the anchor, so that the limiting claws 78 on both sides lock onto the anchor, thus performing secondary fixing of the anchor. When the anchor is no longer needed, the fixing of the sliding sleeve 75 is released. The sliding sleeve 75 and the limiting box 76 are moved along the track 714 to separate the limiting claws 78 from the anchor body. Finally, the threaded rod 710 is rotated in the opposite direction to return the push plate 77 to its initial position for easy use next time. The fourth clamping block 715 is then removed for easy access to the power anchor.

[0052] like Figure 10As shown, a first clamping block for supporting the irregular anchor is fixedly connected inside the irregular anchor box 72. A second clamping block 711, which cooperates to fix the irregular anchor, is engaged with the first clamping block. A fixing buckle 712 is fixedly connected to the irregular anchor box 72, and a fixing rope 713 is provided on the fixing buckle 712 to cooperate in fixing the irregular anchor. Preferably, a fixing ring 718 is fixedly connected to the inner wall of the irregular anchor box 72, and a locking buckle 717 is fixedly connected to the bottom wall inside the irregular anchor box 72. A locking pin 716 for fixing the irregular anchor is provided on the locking buckle 717, and a fixing rope 713 is connected between the locking pin 716 and the fixing ring 718, which can further limit and fix the irregular anchor. When fixing the irregular anchor, place the irregular anchor on the first clamping block, and then snap the second clamping block 711 onto the first clamping block to initially fix the irregular anchor; then tie the fixing rope 713 to the two symmetrically arranged fixing buckles 712 to fix the irregular anchor again; then insert the locking pin 716 into the locking buckle 717, and finally tie the fixing rope 713 between the locking pin 716 and the fixing ring 718; when the irregular anchor is needed, release the fixing of the irregular anchor.

[0053] like Figure 1 and Figure 12 As shown, the chain storage compartment 8 is fixedly installed on the platform. The top of the chain storage compartment 8 is open, and a main shaft 81 is rotatably installed inside the chain storage compartment 8 and coaxially arranged therewith. A fourth motor 82 is fixedly connected to the side of the chain storage compartment 8. The output shaft of the fourth motor 82 is fixedly connected to a secondary shaft 83. A second transmission belt 84 is installed on the outer periphery of the secondary shaft 83 and the main shaft 81. A chain fastener 85 for the anchor chain to pass through is fixedly installed on one side of the main shaft 81. A chain outlet 86 for the anchor chain to be led out is opened on one side of the bottom of the chain storage compartment 8. The chain storage compartment 8 is used to store and assist in the deployment and retrieval of anchor chains. For example, before anchoring, one end of the anchor chain required for anchoring is passed through the chain buckle 85 and fixed to the main shaft 81. Then, the fourth motor 82 is started, causing the main shaft 81 to rotate and wind up the anchor chain, which is then wrapped around the outer circumference of the main shaft 81, thereby storing the anchor chain required for anchoring in the chain storage compartment 8. When preparing to anchor on the sea surface, the free end of the anchor chain is placed at the chain outlet 86, and then the fourth motor 82 is started in reverse. The fourth motor 82 drives the main shaft 81 to rotate, causing the anchor chain to be discharged from the chain outlet 86.

[0054] This invention, through the integrated transmission design of the lifting equipment 4, the chain storage compartment 8, and the control components, enables the automatic completion of anchor hoisting, anchor chain retrieval, and release operations. This eliminates the need for prolonged coordination among multiple personnel, effectively simplifying the operation process, significantly shortening the duration of a single mooring operation, and substantially improving the efficiency of deep-sea anchoring operations while reducing labor and time costs. Furthermore, the underwater deployment of the disc-shaped float 3 and the multi-directional force-bearing structure design of the water tank 61 and supporting columns 2 allow the entire device to adapt to the deep waters and complex geological environments of the South China Sea and other similar waterways. This effectively disperses structural stress caused by wave loads and prevents component fatigue deformation.

[0055] Example 2

[0056] This invention discloses a method for deploying an anchoring device at sea, such as... Figure 13 As shown, it includes the following steps:

[0057] S1: A closed-loop platform is formed by splicing several mounting components 1, and the anchor to be deployed is fixed on the platform.

[0058] When assembling into a closed-loop platform, two adjacent mounting components 1 are connected by connecting plate 15; and the supporting column 2, floating body 3, lifting equipment 4, control component, ballast water component 6, storage anchor component 7 and storage chain compartment 8 are installed on the platform.

[0059] Preferably, the anchor to be deployed is fixed in the power anchor box 71 or the irregular anchor box 72. When fixing the power anchor, the power anchor is placed on the third clamping block, and the first support frame 74 is controlled by the hydraulic cylinder 73 to support and lock the first support frame 74 onto the anchor body, thus achieving initial fixation. The fourth clamping block 715 is then locked onto the third clamping block. Then, the sliding sleeve 75 and the limiting box 76 are moved along the track 714 to a suitable position on the side of the anchor body. The sliding sleeve 75 is then fixed in the current position. Then, the threaded rod 710 is rotated to move the push plate 77 toward the anchor. The push plate 77 drives the limiting claws 78 toward the anchor through the spring 79, so that the limiting claws 78 on both sides lock the anchor, thus performing secondary fixation of the anchor. When fixing the irregular anchor, place the irregular anchor on the first clamping block, and then snap the second clamping block 711 onto the first clamping block to initially fix the irregular anchor; then tie the fixing rope 713 to the two symmetrically arranged fixing buckles 712 to fix the irregular anchor again; then insert the locking pin 716 into the locking buckle 717, and finally tie the fixing rope 713 between the locking pin 716 and the fixing ring 718.

[0060] S2: Transport the platform to the target sea area and adjust the platform to the preset draft depth using the bidirectional water pump 62. When it is necessary to lower the platform's draft, the bidirectional water pump 62 pumps water from the support column 2 into the water storage tank 61. When it is necessary to increase the platform's draft, the bidirectional water pump 62 pumps water from the water storage tank 61 into the support column 2. The draft depth adjusted in a single operation is positively correlated with the amount of water pumped.

[0061] S3: Connect one end of the anchor chain to the anchor, and introduce the other end of the anchor chain from the side of the channel 10 located inside the platform ring. Start the first motor 51, causing the two rotating disks 53 to rotate and transport the anchor chain, so that the anchor chain is led out from the side of the channel 10 located outside the platform ring. The first motor 51 continues to run until the length of the anchor chain passing through the channel 10 reaches the preset length, then turn off the first motor 51 to stop transporting the anchor chain. That is, after starting the first motor 51, the anchor chain enters the channel 10 from the inlet 101, passes through the channel 10, and is discharged from the outlet 102.

[0062] Preferably, the anchor chain is stored in the chain storage compartment 8 beforehand. When step S3 is performed, the anchor chain is exported from the chain storage compartment 8. When exporting the anchor chain, the free end of the anchor chain is placed at the chain outlet 86. Then, the fourth motor 82 is started in reverse. The fourth motor 82 drives the main shaft 81 to rotate, so that the anchor chain is discharged from the chain outlet 86.

[0063] When releasing the limiting fixation of the dynamic anchor, first release the fixation of the sliding sleeve 75, move the sliding sleeve 75 and the limiting box 76 along the track 714 to separate the limiting claw 78 from the anchor body, and finally rotate the threaded rod 710 in the opposite direction to return the push plate 77 to the initial position for easy use next time. Then remove the fourth clamping block 715 to facilitate the use of the dynamic anchor. When releasing the limiting fixation of the irregular anchor, untie all the fixing ropes 713, remove the locking pin 716 from the locking buckle 717, and then remove the first clamping block to facilitate the use of the irregular anchor.

[0064] S4: Simultaneously adjust the hydraulic telescopic rod 58 to make it move downward with the first braking block 59. The first braking block 59 and the second braking block 512 cooperate to engage the anchor chain, limit and fix the anchor chain, and connect one end of the anchor chain that passes through the channel 10 to the mooring mechanism.

[0065] S5: Operate the lifting equipment 4 to lift the anchor to the preset anchoring position, and adjust the hydraulic telescopic rod 58 to make it move upward with the first braking block 59 to release the jamming of the anchor chain.

[0066] S6: Reverse start of the first motor 51, causing the two rotating disks 53 to transmit the anchor chain from the mooring mechanism to the lifting equipment 4, while adjusting the lifting equipment 4 to control the anchor to sink to the preset position in the sea. After the anchor sinks to the preset position in the sea, the first motor 51 is shut off.

[0067] S7: Control the second drive component to rotate and open the second release plates 510 on both sides, control the first drive component to rotate and open the first release plate 510, and the anchor chain will disengage from the sleeve 5; control the lifting equipment 4 to release the anchor and complete the deployment.

[0068] When the second driving component is controlled to rotate and open the second release plates 510 on both sides, the third motor 524 drives the worm gear 525 to rotate. The worm gear 525 meshes with the worm 526, causing the worm gear 525 to drive the worm 526 to rotate. The rotating shaft 527 rotates synchronously with the worm 526, causing the rotating shaft 527 to drive the second release plate 511 to rotate and open. When the first driving component is controlled to rotate and open the first release plate 510, the second motor 513 drives the second transmission shaft 516 through the first reversing gear 514 and the second reversing gear 517. The second transmission shaft 516 drives the third reversing gear 521 to rotate synchronously. The third reversing gear 521 drives the rotating shaft 519 to rotate through the fourth reversing gear 522, thereby causing the rotating shaft 519 to rotate and open the first release plate 510.

[0069] During the anchor descent process, the directional stability of the anchor body is one of the main factors affecting the mooring effect, and the optimal penetration effect of the anchor body directly determines its bearing capacity.

[0070] S8: Adjust the bidirectional water pump 62 again to bring the platform back to the preset draft depth after anchoring.

[0071] In practical applications, if repeated anchoring is required, multiple anchor chains can be stored in the chain storage compartment 8 beforehand, and two anchors can be stored in the anchor storage assembly 7. After the first anchoring, repeat the above steps S1-S8 to complete the second anchoring.
