[0025] Furthermore, a plurality of buoyancy materials 2 are evenly arranged along the length direction of the connecting plate 13 .

[0026] It can be seen from the above description that the arrangement of multiple buoyancy materials 2 can facilitate the adjustment of the quantity according to design requirements later.

[0027] Furthermore, it also includes a first fixing plate 3 , one end of which is locked with the mounting plate 12 , and the other end is locked with the side of the bottom plate 11 ; the surface of the first fixing plate 3 is against the buoyancy material 2 .

[0028] It can be seen from the above description that the buoyancy material 2 is fixed by connecting the mounting plate 12 and the bottom plate 11 up and down through the first fixing plate 3 .

[0029] Furthermore, a first screw hole is provided at a portion of the first fixing plate 3 that abuts against the buoyancy material 2 , and a second screw hole that matches the first screw hole is provided at the buoyancy material 2 .

[0030] It can be seen from the above description that the filled buoyancy material 2 is further fixed by the cooperation between the first screw hole provided on the first fixing plate 3 and the second screw hole on the buoyancy material 2 .

[0031] Furthermore, a reinforcing plate 14 perpendicular to the connecting plate 13 is connected between the bottom plate 11 and the mounting plate 12 .
