Description

Technical Field

[0001] This utility model relates to the field of ship berthing technology, specifically to a drag anchor energy dissipation and buffer device for ship berthing. Background Technology

[0002] During ship berthing, traditional anchor dragging operations usually rely on the gripping force of the ship's own anchor chain to assist in deceleration. However, this direct dragging method causes the anchor chain to vibrate violently during dragging, which is transmitted to the ship's deck structure through the winch, affecting the stability of the ship's precision equipment (such as navigation systems and power units) and even causing structural fatigue damage. Therefore, there is an urgent need for an energy dissipation and buffer device for ship berthing. Utility Model Content

Detailed Implementation

[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. The preferred embodiments described are only examples. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] like Figures 1-5 As shown, the specific embodiment adopts the following technical solution: it includes a fixing seat 1, which is fixedly installed on the ship. A reinforcing seat 20 is fixedly sleeved on the fixing seat 1, and the reinforcing seat 20 is fixedly installed on the ship. The reinforcing seat 20 can provide reinforcement for the fixing of the fixing seat 1 on the ship.

[0027] It also includes:

[0028] The movable seat 2 is movably mounted on the upper part of the fixed seat 1. An anchor chain stopper 3 is fixedly mounted on the upper part of the movable seat 2. A connecting cylinder 4 is fixedly mounted on the bottom of the movable seat 2 and is movably mounted inside the fixed seat 1. The movable seat 2 is provided with a convenient limiting mechanism 5 connected to the fixed seat 1. A limiting ring 15 is fixedly sleeved on the connecting cylinder 4 and is movably mounted in an annular groove 16 opened on the inner annular wall of the fixed seat 1. The limiting ring 15 can limit the movement of the connecting cylinder 4, making the movement of the connecting cylinder 4 within the fixed seat 1 more stable. The movable seat 2 is provided with a rounded corner 17 and a collision buffer ring 18 is fixedly sleeved on the movable seat 2. The rounded corner 17 can reduce the wear generated when the anchor chain moves on the movable seat 2. The collision buffer ring 18 can provide collision buffer on the outside of the movable seat 2, reducing the damage caused by personnel or objects accidentally colliding with the movable seat 2.

[0029] The movable rod 6, of which there are several, is movably inserted into several movable grooves 7 with equal rounded corners on the inner ring wall of the fixed base 1. An oil storage groove 8 is provided on one side of the movable groove 7. A contact block 9 is fixedly provided at one end of the movable rod 6. Several positioning grooves 19 with equal rounded corners are provided on the outer ring wall of the connecting cylinder 4. The contact block 9 is engaged with the positioning grooves 19 and is set to abut against them. The positioning grooves 19 can position and restrict the movable position of the contact block 9 on the outside of the connecting cylinder 4, so as to avoid the phenomenon of the connecting cylinder 4 moving randomly during the energy dissipation and buffering process of the device.

[0030] Spring 10, there are several springs 10, which are movably sleeved on several movable rods 6 respectively. The two ends of the spring 10 are fixedly connected to the abutment block 9 and the inner wall of the fixed seat 1 respectively.

[0031] Piston blocks 11, there are several piston blocks 11, which are fixedly installed at the other end of several movable rods 6, and the piston blocks 11 are movably installed in the oil storage tank 8. An annular oil groove 12 is opened in the side wall of the fixed seat 1, and a liquid flow hole 13 communicating with the oil storage tank 8 is opened on the annular oil groove 12. Damping oil is provided in the annular oil groove 12, the oil storage tank 8 and the liquid flow hole 13.

[0032] The convenient limiting mechanism 5 includes:

[0033] Limiting blocks 5-1, there are several limiting blocks 5-1, which are inserted into the bottom of the movable seat 2 with equal rounded corners. The upper part of the fixed seat 1 is provided with a limiting groove 14 that cooperates with the limiting blocks 5-1. The upper end of the limiting blocks 5-1 is inserted with a threaded rod 5-2 through a threaded rotation. The threaded rod 5-2 is rotatably set in the movable seat 2 through a bearing.

[0034] Gears 5-3, of which there are several, are fixedly sleeved on several threaded rods 5-2 respectively. An internal gear ring 5-4 is rotatably installed in the side wall of the movable seat 2 through a bearing. The several gears 5-3 are all meshed with the internal gear ring 5-4. A control handle 5-5 is inserted into the upper part of the movable seat 2 through a bearing. The control handle 5-5 is fixedly connected to the upper end of the threaded rod 5-2 on the left. Through the cooperation of gears 5-3 and internal gear ring 5-4, the synchronous rotation of several threaded rods 5-2 can be realized, thereby realizing the synchronous control of the limiting state of several limiting blocks 5-1 in the limiting groove 14. After the ship is anchored and moored, the lower end of the limiting block 5-1 can be inserted into the limiting groove 14 to realize the limiting of the movable seat 2 on the fixed seat 1.

[0035] When using this utility model, the anchor is dropped so that the anchor chain passes through the fixed seat 1, the movable seat 2, and the connecting cylinder 4. Then, the anchor chain is fixed using the anchor chain stopper 3. Next, the control handle 5-5 is rotated, which drives the threaded rod 5-2 connected to it to rotate. The gear 5-3 and the internal gear ring 5-4 cooperate to make several threaded rods 5-2 rotate synchronously. Through the rotation of the threaded rods 5-2, the limiting block 5-1 can be moved upward from the limiting groove 14. Then, the vibration generated by the anchor chain during the anchor dragging process will be transmitted to the movable seat 2 and the connecting cylinder 4. The vibration is then transmitted to the spring 10 by the abutment block 9 and the movable rod 6, causing the spring 10 to reciprocate and achieve energy dissipation and buffering. During this process, the movable rod 6 will also drive the piston to move in the oil storage tank 8, so that the damping oil in the oil storage tank 8 and the annular oil tank 12 can flow repeatedly through the liquid flow hole 13. The friction between the hole wall and the oil and the internal friction between the oil molecules will both form a damping force on the vibration.

[0036] Compared with the prior art, the beneficial effects of this utility model are:

[0037] By cooperating with the movable seat 2, connecting cylinder 4, movable rod 6, abutting block 9, spring 10 and piston block 11, the violent vibration generated by the anchor chain during berthing and towing can be provided with energy dissipation buffer, reducing the impact of anchor chain vibration on the ship.

[0038] With the cooperation of the convenient limiting mechanism 5, the movable seat 2 can be conveniently controlled to be at the upper limit of the fixed seat 1, thereby realizing the switching between the energy dissipation buffer state and the normal state of the device.

[0039] The rounded corner 17 can reduce the wear of the anchor chain when it moves on the movable seat 2, and the anti-collision buffer ring 18 can provide collision buffer on the outside of the movable seat 2 to reduce the damage caused by personnel or objects accidentally colliding with the movable seat 2.

[0040] The limiting ring 15 can limit the movement of the connecting cylinder 4, making the movement of the connecting cylinder 4 within the fixed seat 1 more stable.

[0041] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
