Description

Technical Field

[0001] This invention relates to the field of ship mooring technology, and specifically discloses a ship windproof anchor chain locking connection structure and method. Background Technology

[0002] When large ships dock at a pier, they are usually moored using storm lines. As the size of the ship increases, the number of storm lines and storm bollards required to maintain mooring stability also increases. Storm lines are usually connected to bollards by knotting around them. This operation is complex and cumbersome. If the knotting is not completed in time, the storm line will swing violently under the external force of the ship, threatening the safety of the crew. Therefore, the labor cost and safety risks of this work usually increase significantly with the size of the ship. When large ships need to dock at ports with insufficient storm bollards, the safety of the ship's mooring cannot be guaranteed because the number of storm lines that can be effectively installed is limited. Even if a stronger windproof anchor chain is used as an alternative, the low flexibility of the windproof anchor chain makes it difficult to complete the knotting and securing in actual operation. At the same time, under extreme weather conditions such as strong winds, the windproof anchor chain is prone to breakage due to its low toughness and ductility, making it difficult to effectively replace the function of traditional storm lines. Summary of the Invention

[0003] To overcome the drawbacks of large ships requiring excessive storm lines during mooring, resulting in high labor costs and safety risks, and the difficulty in directly replacing them with windproof anchor chains, this invention provides a windproof anchor chain locking connection structure and method for ships.

[0004] The technical solution of the present invention is as follows: a ship windproof anchor chain locking connection structure, comprising a lock body, a fixing bolt fixedly connected to the inside of the lock body, a fixing anchor chain sleeved on the fixing bolt, symmetrically distributed fixing slide rails fixedly connected to the inside of the lock body, a fixing connecting block fixedly connected to the inside of the lock body near the fixing bolt, a sliding bolt arranged between the symmetrically distributed fixing slide rails, the sliding bolt sliding along the symmetrically distributed fixing slide rails, a windproof anchor chain connected to the ship sleeved on the sliding bolt, a buffer elastic element fixedly connected between the sliding bolt and the fixing connecting block, and a quick-connect mechanism arranged on the side of the lock body away from the fixing bolt and the sliding bolt, the quick-connect mechanism being used to quickly lock the end of the fixing anchor chain away from the fixing bolt.

[0005] As a further preferred embodiment, the side of the fixed slide rail away from the fixing bolt is provided with a reinforcing part.

[0006] As a further preferred embodiment, the fixed connecting block is slidably connected to a sliding member, and an auxiliary elastic member is installed between the two, with the sliding member located on the movement path of the sliding bolt.

[0007] As a further preferred embodiment, the quick-connect mechanism includes a blocking strip fixed to the lock body. A rotating bolt is rotatably connected to the side of the lock body away from the fixing bolt and the sliding bolt. The rotating bolt penetrates the lock body and has a slot on the outside of the lock body. A locking pin is provided on the inside of the lock body of the rotating bolt. The locking pin is used to lock the end of the anchor chain away from the fixing bolt. The blocking strip is used to restrict the rotation of the locking pin. A fixing component is provided in the lock body for auxiliary fixing of the locking pin.

[0008] As a further preferred embodiment, a seal with the same cross-sectional shape as the slot is slidably connected within the slot, and a first elastic element is installed between the seal and the slot.

[0009] As a further preferred embodiment, the fixing component includes an auxiliary locking member, which is slidably connected to the side of the blocking strip facing the rotating bolt. A second elastic member is installed between the auxiliary locking member and the blocking strip, and the auxiliary locking member is used to limit the locking pin.

[0010] As a further preferred embodiment, the lock body is provided with two symmetrically distributed placement through holes with their central axes coinciding. The symmetrically distributed placement through holes are both located on the side of the blocking strip away from the auxiliary locking member, and between the fixing bolt and the rotating bolt. The lock body is provided with a drive rod that passes through the two placement through holes. One end of the drive rod is provided with a drive protrusion, the cross-section of which has the same shape as the cross-section of the slot. The other end of the drive rod is rotatably and slidably connected to a drive handle.

[0011] As a further preferred embodiment, a locking member is slidably connected to the middle of the drive handle, and a wedge block is fixedly connected to the locking member inside the drive handle. A third elastic member is installed between the wedge block and the drive handle, and the wedge block is used to restrict the movement of the drive rod.

[0012] As a further preferred embodiment, a sliding plate is slidably connected to the side of the lock body near the blocking bar, and a fourth elastic element is installed between the two. A limiting block is slidably connected to the side of the lock body near the blocking bar. The sliding plate is slidably connected to the limiting block through an inclined groove. The driving rod and the driving handle are both used to push the sliding plate to move. The limiting block is used to limit the auxiliary locking component.

[0013] A method for using a ship's windproof anchor chain lock connection structure, based on the above-mentioned ship's windproof anchor chain lock connection structure, the specific method of use includes the following steps: Step 1: Bring the lock body and windproof anchor chain from the ship to the storm bollard, and unlock the drive handle and drive rod by dragging the locking device, and remove the drive handle and drive rod from the placement through hole; Step 2: Wrap the anchor chain bolt around the storm cable bollard and slip the end of the chain away from the anchor bolt onto the locking post; Step 3: Insert the drive protrusion into the slot, and use the drive handle to rotate the drive protrusion, rotating bolt and locking pin until the locking pin contacts the blocking strip after passing the auxiliary locking part; Step 4: Pull the drive protrusion out of the slot, and reinsert the drive handle and drive rod into the placement through hole, so that the drive rod passes through the end of the fixed anchor chain. The drive handle and drive rod push the sliding plate to move, the sliding plate pushes the limit block to move, and the limit block limits the auxiliary locking component. Step 5: When the ship is subjected to strong winds, the cushioning elastic elements and auxiliary elastic elements provide cushioning for the sliding bolts and windproof anchor chains in stages; Step 6: When mooring ends, release the limit on the drive handle and drive rod by dragging the locking device, and remove the drive handle and drive rod from the placement through hole, so that the sliding plate and limit block release the limit on the auxiliary locking device. Step 7: Drive the drive lug, rotating bolt and locking pin to rotate by driving the drive handle, so that the fixed anchor chain rotates back to the lock body, and remove the end of the fixed anchor chain from the locking pin; Step 8: Reinsert the drive handle and drive rod into the placement through hole, and reattach the lock body and windproof anchor chain to the vessel.

[0014] The beneficial effects of this invention compared to the prior art are as follows: This invention replaces storm lines with lock bodies and windproof anchor chains, and uses buffer elastic elements to buffer the sliding bolts and the windproof anchor chains on them, thereby indirectly increasing the toughness and ductility of the anchor chains. This allows large ships to safely moor and berth even when there are insufficient storm line bollards available, thus specifically solving the difficulties and pain points of safe berthing for large ships and improving the safety of berthing for large ships.

[0015] This invention relies on segmented increase of the resistance to the movement of the sliding bolt by buffer elastic elements and auxiliary elastic elements, thereby providing the buffer force required for the windproof anchor chain under different wind forces and reducing the risk of the windproof anchor chain breaking due to prolonged exposure to rigid tension.

[0016] This invention increases the pulling force of the locking pin on the fixed anchor chain by using a drive rod, a drive protrusion, and a drive handle. At the same time, the drive rod provides additional fixation to the locking pin and limits the pulling direction of the fixed anchor chain, thereby increasing the fixing force between the fixed anchor chain, the locking pin, and the lock body, and thus increasing the overall stress stability of the device.

Detailed Implementation

[0019] The technical solution will be further explained below with reference to specific embodiments. It should be noted that, unless otherwise specified, the terms "up," "down," "left," and "right" used in this document to indicate direction refer only to the structure described in the appendix. Figure 1 In terms of their position within the text, the serial numbers assigned to components, such as "first," "second," etc., are merely for distinguishing the objects being described and have no sequential or technical meaning.

[0020] Example 1 discloses a ship windproof anchor chain locking connection structure to solve the problem that large ships require too many storm lines when mooring, resulting in high labor costs and safety risks, and that it is difficult to directly replace them with windproof anchor chains.

[0021] A ship windproof anchor chain locking connection structure, referring to Figures 1-5 The lock body 1 consists of two triangular plates with arc-shaped angles and at least two reinforcing bolts 102. A fixing bolt 101 is fixedly connected to the inside of the lock body 1. A fixing anchor chain is fitted onto the fixing bolt 101. The fixing anchor chain is used to wrap around or fit onto existing storm bollards. Two symmetrically distributed fixing slide rails 2 are fixedly connected to the inside of the lock body 1. A fixing connecting block 3 is fixedly connected to the inside of the lock body 1 near the fixing bolt 101. A sliding bolt 4 is provided between the two fixing slide rails 2. The sliding bolt 4 is fitted with a windproof anchor chain that is connected to the ship. The other end of the windproof anchor chain is connected to the ship by an existing method (wound onto a storm bollard on the ship or installed on the ship by a reel). A buffer elastic element 41, which is a strong tension spring, is fixedly connected between the sliding bolt 4 and the fixing connecting block 3. A quick-connect mechanism is provided on the side of the lock body 1 away from the fixing bolt 101 and the sliding bolt 4. The quick-connect mechanism is used to quickly lock the end of the fixing anchor chain away from the fixing bolt 101.

[0022] In the above scheme, the reinforcing bolt 102 and the fixing bolt 101 can be bolts or cylindrical parts welded to the lock body 1. The buffer elastic element 41 buffers the sliding bolt 4 and the windproof anchor chain on it, thereby increasing the toughness and ductility of the anchor chain. This allows the windproof anchor chain to more effectively replace the traditional storm line, enabling large ships to safely moor and berth even when the number of available storm line bollards is insufficient. This solution specifically addresses the difficulties and pain points of safe berthing for large ships and improves the safety of berthing for large ships.

[0023] As a further preferred option, refer to Figure 4 and Figure 5 A reinforcing part 21 is provided on the side of the fixed slide rail 2 away from the fixing bolt 101. The thickness of the reinforcing part 21 is not less than the diameter of the fixing bolt 101, and the reinforcing part 21 covers at least 180° of the end of the fixed slide rail 2. The fixed connecting block 3 is slidably connected to the sliding member 5, and an auxiliary elastic member 51 is installed between the two. The auxiliary elastic member 51 is a strong tension spring. The sliding member 5 is located on the moving path of the sliding bolt 4. When the sliding bolt 4 moves to the left and contacts the sliding member 5, it drives the sliding member 5 to move to the left together. The left side of the sliding member 5 is provided with spaced first reinforcing ribs 52. The first reinforcing ribs 52 are used to reduce the material used in the sliding member 5 while increasing the strength of the sliding member 5.

[0024] In the above scheme, the fixed slide rail 2 uses the elastic force of its reinforcing part 21, the buffer elastic element 41 and the auxiliary elastic element 51 to hinder the movement of the sliding bolt 4. The buffer elastic element 41 and the auxiliary elastic element 51 are used to increase the resistance to the movement of the sliding bolt 4 in segments. The reinforcing part 21 reduces the probability that the fixed slide rail 2 will be crushed by the sliding bolt 4 due to excessive tension.

[0025] As a further preferred option, refer to Figures 5-7 The quick-connect mechanism includes a blocking strip 6, which is fixed inside the lock body 1. The blocking strip 6 gradually tilts to the right from back to front. A rotating bolt 7 is rotatably connected to the rear side of the lock body 1. The rotating bolt 7 penetrates the lock body 1 and has a slot 71 on the outside of the lock body 1. The slot 71 can be set in any shape that facilitates the insertion of tools by the operator for rotation. In this embodiment, the slot 71 is snowflake-shaped. The operator can use a wrench or crank with a plug of the same shape to rotate the rotating bolt 7. A sealing element 73 with the same cross-sectional shape is slidably connected inside the slot 71. A first elastic element 74 is installed between the sealing element 73 and the slot 71. One elastic element 74 is a spring, and the sealing element 73 is used to seal the slot 71 when the operator does not insert the wrench or crank, thereby reducing the probability of foreign objects entering the slot 71 or dust accumulating inside the slot 71. The rotating bolt 7 is L-shaped, and a locking pin 72 is provided on the inner side of the lock body 1. The blocking strip 6 is used to restrict the rotation of the locking pin 72. The locking pin 72 can rotate with the rotating bolt 7 to the outside of the lock body 1, making it convenient for the operator to put the fixing anchor chain on the locking pin 72. The lock body 1 is provided with a fixing component for auxiliary fixing of the locking pin 72. In the initial non-working state, the locking pin 72 is located on the outside of the lock body 1 (refer to...). Figure 6 (As shown).

[0026] In the above scheme, the rotating bolt 7, the fixing bolt 101, and the sliding member 5 that is dragged to the reinforcing part 21 are respectively located at the three vertices of the triangle near the lock body 1, so that the lock body 1 is subjected to relatively uniform force under extreme stress, thereby increasing the firmness of the lock body 1. The workers can quickly position the fixed anchor chain by rotating the rotating bolt 7 and the locking pin 72, thereby reducing the safety risks that the workers need to bear by reducing the workers' working time.

[0027] As a further preferred option, refer to Figures 5-7 The fixing component includes an auxiliary locking member 8, which is slidably connected to the left side of the blocking strip 6. A second elastic member 81, which is a spring, is installed between the auxiliary locking member 8 and the blocking strip 6. Two symmetrically distributed pressing inclined surfaces are provided on the front side of the auxiliary locking member 8, and the distance between the two pressing inclined surfaces gradually decreases from back to front. A second reinforcing rib 82 is provided on its rear side to increase the strength of the auxiliary locking member 8. The auxiliary locking member 8 is used to limit the locking post 72.

[0028] As a further preferred option, refer to Figures 1-3 , Figures 5-7 , Figure 9 and Figure 10The lock body 1 has two symmetrically distributed through holes 103 on its right side, with their central axes coinciding. These two through holes 103 are located on the upper and lower triangular plates of the lock body 1, respectively. Both through holes 103 are located to the right of the blocking strip 6 and between the fixing bolt 101 and the rotating bolt 7. The lock body 1 has a drive rod 9 that passes through the two through holes 103. The drive rod 9 and the through holes 103 are considered detachably connected. When the drive rod 9 is inserted into the through hole 103, it passes through the end of the fixing anchor chain wrapped around the locking pin 72. One end of the drive rod 9 has a drive protrusion 91, the cross-section of which is the same shape as the cross-section of the slot 71, both being snowflake-shaped. The other end of the drive rod 9 is rotatably and slidably connected to a drive handle 92. The operator inserts the drive protrusion 91 into the cross-section of the slot 71 and rotates the rotating bolt 7 by using the drive handle 92. The drive rod 9 is initially inserted into the through hole 103 in a non-working state (see reference). Figure 2 As shown), at this time, the drive lever 9 is located in the middle of the drive handle 92.

[0029] In the above scheme, the locking post 72 is assisted in being fixed by the auxiliary locking component 8 and the blocking strip 6, reducing the risk of the locking post 72 rotating and slipping off in the reverse direction during installation. The drive rod 9 fixes the end of the fixed anchor chain by restricting the direction of the fixed anchor chain wrapped around the locking post 72. On the one hand, it prevents the fixed anchor chain from driving the rotating bolt 7 and the locking post 72 to rotate away from the blocking strip 6. On the other hand, it ensures that when the fixed anchor chain is subjected to tension, the direction of the tension is the direction that drives the rotating bolt 7 and the locking post 72 to rotate closer to the blocking strip 6, so that the fixed anchor chain, rotating bolt 7 and locking post 72 form a self-locking relationship, thereby providing a more reliable fixation for the end of the fixed anchor chain.

[0030] As a further preferred option, refer to Figure 7 , Figure 9 and Figure 10 A locking element 93 is slidably connected to the middle of the drive handle 92. A square groove for the locking element 93 to pass through is provided on the lock body 1 near the through hole 103. This square groove communicates with the through hole 103. A wedge-shaped block 94 is fixedly connected to the locking element 93 within the drive handle 92. Figure 9 and Figure 10 For example, the side of the wedge block 94 facing the drive rod 9 is an inclined surface, while the side of the wedge block 94 away from the drive rod 9 is a vertical surface. A third elastic element 95, which is a spring, is installed between the wedge block 94 and the drive handle 92. The wedge block 94 initially limits the drive rod 9 in its non-operational state (see reference). Figure 7 (State of drive lever 9).

[0031] In the above solution, the driving rod 9, which moves to the middle of the driving handle 92, is locked by the locking member 93 and the wedge block 94, thus limiting the driving rod 9 to the middle of the driving handle 92 and stably restricting the driving rod 9 within the placement through hole 103.

[0032] As a further preferred option, refer to Figure 7 and Figure 8 A sliding plate 10 is slidably connected to the side of the lock body 1 near the blocking bar 6. An inclined surface is provided on the front side of the sliding plate 10. The drive rod 9 and the drive handle 92 are both used to press the inclined surface on the sliding plate 10. When the sliding plate 10 is pressed by the drive rod 9 and the drive handle 92, it retracts into the lock body 1. A fourth elastic element 111 is installed between the two. The fourth elastic element 111 is a spring. In the initial non-working state (i.e., the drive rod 9 is inserted into the placement through hole 103), the fourth elastic element 111 is in the stored state. A dustproof plate is provided at the sliding connection of the lock body 1 near the sliding plate 10 to reduce the probability of dust entering the rear side of the sliding plate 10. A limit block 11 is slidably connected to the side of the lock body 1 near the blocking bar 6. An inclined groove that gradually slopes downward from front to back is provided on the sliding plate 10. The sliding plate 10 is slidably connected to the limit block 11 through the inclined groove. The limit block 11 is used to limit the auxiliary locking part 8.

[0033] In the above scheme, by inserting the drive rod 9 into the placement through hole 103, the sliding plate 10 pushes the limiting block 11 to move, and the limiting block 11 is inserted between the auxiliary locking member 8 and the blocking strip 6, so that the auxiliary locking member 8 cannot move relative to the blocking strip 6, thereby increasing the limiting force of the auxiliary locking member 8 on the locking post 72, and thus increasing the stability of the device.

[0034] The working principle of the above scheme is as follows: When preparing to dock a large vessel at the pier, the staff first used a small boat to move the device and the end of the windproof anchor chain connected to the device to the storm bollard at the pier. Then the staff prepared to fix the anchor chain to the storm bollard.

[0035] First, the worker pulls down the locking part 93 on the drive handle 92. The locking part 93 moves the wedge block 94 downward to release the restriction on the drive rod 9. The third elastic element 95 compresses and stores force. The worker manually moves the drive handle 92 and moves its end to the position aligned with the drive rod 9. Then, the worker rotates the drive handle 92 so that the axis of the drive handle 92 and the axis of the drive rod 9 rotate to the same straight line, and releases the locking part 93. The locking part 93 and the wedge block 94 are reset under the elastic force of the third elastic element 95. The worker pulls the drive rod 9 and the drive handle 92 out of the placement through hole 103. The sliding plate 10 moves forward under the action of the fourth elastic element 111. The limiting block 11 retracts into the lock body 1 under the action of the inclined groove on the sliding plate 10. The worker drags the fixed anchor chain and wraps the fixed anchor chain around the storm cable bollard (no need to wrap it multiple times).

[0036] After the workers wrap the anchor chain around the storm cable bollard, they place the end of the anchor chain (if there is a long excess, select a locking ring that can just tighten the anchor chain and fit onto the locking post 72) onto the locking post 72. Then, the workers align the drive protrusion 91 on the drive rod 9 with the slot 71 and press the drive protrusion 91 into the slot 71. The drive protrusion 91 compresses the seal 73, causing the first elastic element 74 on the seal 73 to compress and store force until the seal 73 moves to the bottom of the slot 71. The workers then rotate the drive handle 92 to a position perpendicular to the drive rod 9, and then use the drive handle 92... 2. When the drive rod 9 and the rotating bolt 7 are rotated, the locking pin 72 passes the pressing inclined surface on the auxiliary locking part 8 during rotation. By pressing the pressing inclined surface on the left side of the auxiliary locking part 8, the second elastic element 81 is compressed and passes through the auxiliary locking part 8. Then, the pressing inclined surface on the right side of the auxiliary locking part 8 is pressed tightly against the locking pin 72 under the action of the second elastic element 81 until the rotating bolt 7 drives the locking pin 72 and the fixed anchor chain end to rotate to the position of contact with the blocking strip 6. Because the drive handle 92 and the drive rod 9 form a force-saving lever in the above process, the chain can be wrapped more tightly on the storm cable bollard.

[0037] After the locking pin 72 and the blocking strip 6 come into contact, the worker pulls the drive protrusion 91 out of the slot 71. At this time, the locking pin 72 is limited by the auxiliary locking member 8 and cannot move. The sealing member 73 moves back to the uppermost side of the slot 71 under the action of the first elastic member 74. After the worker swings the drive rod 9 and the drive handle 92 to a coaxial state, they are reinserted into the placement through hole 103, ensuring that the drive rod 9 is inserted into the locking ring of the fixed anchor chain end, so that the drive rod 9 exerts force on the fixed anchor chain end. To restrict movement, the drive handle 92, during insertion into the placement through hole 103, presses against the inclined surface of the sliding plate 10 and pushes the sliding plate 10 to move backward. The fourth elastic element 111 compresses and stores force, and the sliding plate 10 pushes the limiting block 11 upward through its inclined groove, causing the limiting block 11 to be stuck between the blocking strip 6 and the auxiliary locking member 8. At this time, the auxiliary locking member 8 cannot move backward, forcing the locking pin 72 to be unable to rotate, thereby firmly fixing the fixed anchor chain end and the locking pin 72 to the lock body 1.

[0038] After the operator fully inserts the drive rod 9 and drive handle 92 into the placement through hole 103, the operator swings the drive handle 92 to a horizontal position, and then moves the drive rod 9 to the middle of the drive handle 92. During the movement, the drive rod 9 contacts the inclined surface of the wedge block 94 and pushes the wedge block 94 and locking member 93 downward. The third elastic member 95 compresses and stores force until the drive rod 9 passes the wedge block 94. Under the elastic force of the third elastic member 95, the wedge block 94 pops outward and limits the drive rod 9. The operator does not need to move the drive rod 9 and drive handle 92 to other positions, nor does the operator need to carry an additional rotating tool to turn the rotating bolt 7.

[0039] After the workers install this device on all storm bollards, when the ship is moored and encounters strong winds that cause it to move away from the dock, the ship will first move the sliding bolt 4 by pulling the windproof anchor chain. The buffer elastic element 41 will stretch and store force, simulating the toughness and extensibility of the cable, reducing the possibility of the windproof anchor chain being directly broken by rigid tension. If the sliding bolt 4 continues to move to the left, when the sliding bolt 4 and the sliding element 5 come into contact, the sliding element 5 will move to the left together, and the auxiliary elastic element 51 will stretch and store force to further buffer the windproof anchor chain. If the wind force can still pull the sliding bolt 4 to move to the left, when the sliding bolt 4 moves to the end of the fixed slide rail 2 and comes into contact with the reinforcement part 21, it will become rigidly connected, and the sliding bolt 4 will not move to the left any further. Subsequently, when the wind force subsides, the buffer elastic element 41 and the auxiliary elastic element 51 will jointly pull the sliding bolt 4 to move and reset.

[0040] When the ship is about to leave the dock, the staff unlocks the drive handle 92 and drive rod 9 by pulling the locking piece 93 again, and removes the drive handle 92 and drive rod 9 from the placement through hole 103. The limiting block 11 and sliding plate 10 release the limiting of the auxiliary locking piece 8 under the action of the fourth elastic member 111. The staff inserts the drive protrusion 91 into the slot 71, and drives the rotating bolt 7 and locking pin 72 through the drive handle 92 to pass through the auxiliary locking piece 8 and continue to rotate until the locking pin 72 rotates to the outside of the lock body 1. The staff reinserts the drive handle 92 and drive rod 9 into the placement through hole 103, then removes the end of the fixed anchor chain from the locking pin 72, and removes the fixed anchor chain from the storm bollard. Finally, the staff takes the device and the windproof anchor chain back to the ship by small boat.

[0041] Example 2, based on Example 1, proposes a method for using a ship's windproof anchor chain lock connection structure. The specific method for using this ship's windproof anchor chain lock connection structure, based on the above examples, includes the following steps: Step 1: Take the lock body 1 and the windproof anchor chain from the ship to the storm bollard, and unlock the drive handle 92 and drive rod 9 by dragging the locking part 93, and take the drive handle 92 and drive rod 9 out of the placement through hole 103; Step 2: Wrap the anchor chain bolt around the storm cable bollard and slip the end of the chain away from the anchor bolt 101 onto the locking post 72; Step 3: Insert the drive protrusion 91 into the slot 71, and drive the drive protrusion 91, the rotating bolt 7 and the locking pin 72 to rotate through the drive handle 92 until the locking pin 72 contacts the blocking strip 6 after passing the auxiliary locking piece 8. Step 4: Pull the drive protrusion 91 out of the slot 71, and reinsert the drive handle 92 and drive rod 9 into the placement through hole 103, so that the drive rod 9 passes through the fixed anchor chain end. The drive handle 92 and drive rod 9 push the sliding plate 10 to move, the sliding plate 10 pushes the limiting block 11 to move, and the limiting block 11 limits the auxiliary locking part 8. Step 5: When the ship is subjected to strong winds, the buffer elastic element 41 and the auxiliary elastic element 51 provide buffering for the sliding bolt 4 and the windproof anchor chain in stages.
