The charging and discharging plate 1 is fixedly connected to both ends of a mounting structure 4 by welding. The mounting frame 2 is located on the outer side of the mounting structure 4, and connecting structures 3 are fixedly connected to both ends of the mounting frame 2. The connecting structures 3 include a sealing shell 31, with a sealing ring 32 fixedly connected to the lower end of the sealing shell 31 and mounting screws 33 spirally connected to the upper end of the sealing shell 31. A buffer device 34 is fixedly connected to the upper end of the mounting structure 4 by welding. The mounting structure 4 includes a mounting base 41, with a mounting hole 42 at the upper end. The mounting screws 33 include hexagonal heads 331. The lower end of the corner head 331 is fixedly connected to a first screw 332. A limit groove 333 is opened on the inner side of the first screw 332. A second screw 334 is provided on the inner side of the first screw 332. A sliding groove 335 is opened on the outer side of the second screw 334. A spring 336 is fixedly connected to the inner side of the sliding groove 335. A limit block 337 is fixedly connected to the other end of the spring 336. The limit block 337 and the sliding groove 335 are slidably connected. The bottom of the second screw 334 is spirally connected to the mounting hole 42. The buffer device 34 includes a centering sleeve 341. A disc spring 342 is installed on the inner side of the centering sleeve 341. A buffer pad 343 is installed on the outer side of the disc spring 342.
[0031] As a further implementation of the above technical solution: by setting the center points of the first screw 332 and the second screw 334 to be on the same vertical line, the first screw 332 has a U-shaped vertical cross section, the first screw 332 and the second screw 334 are nested together, and the first screw 332 and the second screw 334 are in close contact, so that the mounting screw 33 can adapt to mounting holes 42 of different depths during the installation process, which facilitates the accurate installation and adjustment of the charging and discharging plate 1 in the complex marine installation environment;
[0032] As a further implementation of the above technical solution: two mounting screws 33 and mounting holes 42 are provided, which are symmetrically arranged and correspond to each other. The inner side of the mounting hole 42 is threaded, and the lower end of the mounting screw 33 is spirally connected to the inner side of the mounting hole 42. This special structure can ensure the firmness of the connection after installation and prevent the screw from loosening during ship vibration, thereby ensuring a tight connection between the connection structure 3 and the mounting structure 4.
[0033] As a further implementation of the above technical solution: two buffer devices 34 are provided. The upper end of the buffer device 34 is in close contact with the inner side of the sealing shell 31. The buffer devices 34 are symmetrically arranged on the upper end of the mounting base 41. The center point between the buffer device 34 and the mounting hole 42 is located on the same vertical line. The centering sleeve 341 ensures the stability of the buffer device 34 during the vibration process, so that the buffering effect can be uniformly and effectively exerted, and ensure that the charging and discharging plate 1 can operate stably in the ship vibration environment.
[0034] As a further implementation of the above technical solution: four connection structures 3 and four installation structures 4 are provided. The connection structures 3 and four installation structures 4 are arranged symmetrically from top to bottom, correspond to each other, and are parallel to each other. The spiral connection between the sealing shell 31 and the mounting screw 33, and the fastening connection between the sealing shell 31 and the installation structure 4 through the mounting screw 33, ensure the stability of the overall structure and prevent loosening during ship vibration.
[0035] As a further implementation of the above technical solution: a plurality of disc springs 342 and buffer pads 343 are provided, with the buffer pads 343 positioned between the disc springs 342. The disc springs 342 are mirror images of the buffer pads 343 with their diameters as the axis. The disc springs 342 and buffer pads 343 are staggered, and the center points of the disc springs 342 and buffer pads 343 are located on the same vertical line. This structure enables the buffer device 34 to effectively absorb and disperse vibration energy in all directions, providing good protection for the charging and discharging plate 1 and improving the buffering effect of the buffer device 34.
[0036] As a further implementation of the above technical solution: two limiting grooves 333 are provided, one side of the limiting block 337 is set as arc, the vertical section of the limiting groove 333 is set as U-shaped, the limiting grooves 333 are symmetrically arranged inside the first screw 332, and the limiting grooves 333 are parallel to each other. The limiting grooves 333 can adapt to the mounting holes 42 of different depths, which facilitates the installation of the charging and discharging board 1.
[0037] Workflow: First, align the connecting structures 3 at both ends of the mounting frame 2 with the mounting structures 4 at both ends of the charging / discharging board 1. Position the hexagonal head 331 of the mounting screw 33 upwards, preparing to install it onto the sealing shell 31 of the connecting structure 3. Secure the mounting screw 33 to the sealing shell 31 by spirally connecting the first screw 332 of the mounting screw 33 to the upper end of the sealing shell 31. Then, align the second screw 334 at the lower end of the mounting screw 33 with the mounting hole 42 on the mounting structure 4. During the insertion of the second screw 334 into the mounting hole 42, the spring 336 is in a stretched state. The limiting block 337 is located inside the slide groove 335. Rotating the first screw 332 will cause the limiting block 337 to engage inside the limiting groove 333, driving the second screw 334 to rotate and install. After the second screw 334 is spirally inserted into the mounting hole 42, rotate the first screw 332 in the opposite direction. During rotation, one arc-shaped side of the limiting block 337 will... During rotation, the spring 336 is compressed, thus disengaging from the inner side of the limiting groove 333. Continued rotation causes the bottom of the hexagonal head 331 to fit tightly against the upper end of the sealing shell 31, achieving a stable connection between the mounting screw 33 and the mounting hole 42. This secures the connecting structure 3 and the mounting structure 4 together. The sealing ring 32 is fixedly connected to the lower end of the sealing shell 31 for sealing during installation. When the ship vibrates during navigation, the charging / discharging plate 1 is affected by the vibration. The vibration is transmitted to the mounting structure 4 and then acts on the buffer device 34. The disc spring 342 and the buffer pad 343 begin to function. The vibration causes the disc spring 342 to undergo elastic deformation, while the buffer pad 343 absorbs and disperses the vibration energy between the disc springs 342, reducing the impact of vibration on the charging / discharging plate 1 and the mounting structure 4. Simultaneously, the centering sleeve 341 ensures the stability of the buffer device 34 during vibration, ensuring the stable operation of the charging / discharging plate 1 and protecting it from vibration damage.
[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
