However, the marine power box has a large load. When replacing the battery on the ship, the container base on the existing ship often has a rigid collision with the marine power box, causing the box body to vibrate, which will have an adverse impact on the equipment inside the box. In the long run, it may cause the fasteners of the equipment and battery pack to loosen and damage the inside of the box body. Due to the influence of water navigation, the anti-corrosion layer of the container base on the ship is often damaged after contact and collision with the container corner fittings during use, and it is easily rusted. Moreover, it is time-consuming and laborious to replace the existing fixed base after rusting. Summary of the Utility Model

[0021] Please refer to Figure 1 , in the embodiment of the present utility model, a buffer base for a marine container is disclosed, which includes a fixed seat 1, a movable seat 2 and a buffer mechanism 3. The fixed seat 1 can be fixed on the surface of the ship deck 5 by means of threaded connection or welding, etc. The movable seat 2 is vertically nested in the fixed seat 1. The buffer mechanism 3 is vertically arranged, with the top abutting against the movable seat 2 and the bottom fixed to the fixed seat 1 or the ship deck 5. The movable seat 2 is provided with a twist lock assembly 4 to fix the marine container.

[0022] For the structure of the movable seat 2, please refer to Figure 2 , the movable seat 2 includes a support flat plate 21, a support wall 22 and four guide columns 23. The support flat plate 21 is horizontally arranged, and the support wall 22 and the guide columns 23 are both vertically arranged. A long strip-shaped twist lock hole 24 is formed in the middle of the support flat plate 21. The support wall 22 is annular, and four reinforcing plates 25 are integrally formed on the outer periphery of the support wall 22. The top sides of the support wall 22 and the reinforcing plates 25 are welded to the bottom side of the support flat plate 21 and are integrally located in the middle of the bottom side of the support flat plate 21. The inner space of the support wall 22 communicates with the twist lock hole 24.

[0023] The horizontal cross-section of the support flat plate 21 is rectangular. The four guide columns 23 are respectively welded to the four top corners of the bottom side of the support flat plate 21. The fixed seat 1 is provided with guide grooves 11 corresponding to the guide columns 23. For the structure of the fixed seat 1, please refer to Figure 3 , the cooperation between the guide columns 23 and the guide grooves 11 realizes the vertical nesting between the movable seat 2 and the fixed seat 1, so that the movable seat 2 can only move vertically relative to the fixed seat 1.

[0024] To prevent the movable seat 2 from detaching from the fixed seat 1, the moving distance of the guide columns 23 needs to be less than the length of the guide columns 23 themselves, and the designs of the guide columns 23 in the guide grooves 11 are all located outside the support wall 22, which will not affect the arrangement of the buffer mechanism 3 and the twist lock assembly 4.

[0025] Please refer to Figure 4 and Figure 5 , and at the same time in combination with Figure 1, the twist lock assembly 4 includes a twist lock 41, a lever 42 and a lock base 43. The twist lock 41 includes a lock head 411, a lock rod 412 and a lock handle 413. The lock head 411 and the lock handle 413 are respectively located at both ends of the lock rod 412, and the lever 42 is perpendicularly welded to the lock rod 412. The lock base 43 is sleeved on the lock rod 412 and the lever 42. The lock base 43 is of a symmetric structure and can be fixed with bolts or pins after being sleeved on the lock rod 412. The lock base 43 is located at one end close to the lock head 411 and is provided with a horizontal lever slot 44. When manually operating the lever 42, the lever 42 can move within the lever slot 44, and the movement of the lever 42 drives the twist lock 41 to rotate. The lock handle 413 passes through the twist lock hole 24, the lock rod 412 penetrates through the support flat plate 21, and the lock handle 413 is hidden inside the support wall 22, and the support wall 22 provides a space for the rotation of the lock handle 413; the lock head 411 and the lock base 43 are located on the top side of the support flat plate 21 and directly act on the corner fittings of the container. To position the twist lock assembly 4, a positioning block 26 is also provided on the top side of the support flat plate 21. When installing the twist lock assembly 4, first pass the twist lock 41 through the twist lock hole 24, and then fit the groove 45 of the lock base 43 with the positioning block 26.

[0026] Combined with Figure 1 and Figure 6 , the buffer mechanism 3 can be a hydraulic cylinder or rubber. In this embodiment, a hydraulic cylinder is taken as an example. The hydraulic cylinder is fixed to the ship deck 5, and its head and most parts are hidden below the deck 5. The cylinder rod 31 of the hydraulic cylinder passes through the fixed seat 1, and a buffer block 32 is fixed at the end of the cylinder rod 31; the buffer block 32 is made of nylon material, and the buffer block 32 directly contacts the bottom sides of the support wall 22 and the reinforcing plate 25. The support wall 22 and the reinforcing plate 25 cooperate with the buffer block 32 to make the force on the cylinder uniform, while the buffer block 32 is designed to reduce the wear caused by the buffer mechanism 3 to the movable seat 2. Based on the above structure, a perforation 12 for the passage of the cylinder rod 31 also needs to be opened in the middle of the fixed seat 1, and at the same time, a space for the movement of the support wall 22 and the buffer block 32 is provided.

[0027] A set of the present utility model is equipped on the bottom side corner fittings of the marine container. Before placing the marine container, first place the twist lock assembly 4 on the movable seat 2. After the container is placed, it is subjected to a buffer stroke by the buffer mechanism 3, and then the movable seat 2 contacts the fixed seat 1, transferring the load to the hull structure, keeping the container body stable, and eliminating the influence of vibration on the equipment and fasteners inside the container. Finally, operate the lever 42 to relatively fix the corner fitting to the movable seat 2.

[0028] In summary, the present utility model adopts the design of the movable seat 2 and the buffer mechanism 3, so that when the marine container contacts the movable seat 2, the container body remains stable, eliminating the influence of vibration during placement on the equipment and fasteners inside the container; at the same time, it is convenient to replace after the movable seat 2 is corroded, facilitating the maintenance of the entire buffer base.

[0029] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
