[0039] Embodiment 1

[0040] In order to solve the problem that the fixing device in the prior art is difficult to install the limiting rod along the limiting hole, thereby easily causing the floating platform to be affected by the inclination of the limiting rod, and unable to rise and fall when the water level rises and falls or inclined during the rising and falling process, thereby affecting the use or stability of the floating platform. Figures 1-4 As shown in the figure, a floating platform fixing device is provided, which comprises a bottom plate 1 with a limiting hole 4 arranged on a floating platform, an installation hole 2 arranged on the bottom plate 1 and a bolt 3 matched with the installation hole 2, two groups of installation blocks 5 are arranged opposite along the center of the limiting hole 4, a U-shaped groove 6 is arranged on each installation block 5, and a limiting and fixing structure 8 for centrally limiting and installing the limiting rod 7, horizontally limiting and moving and longitudinally sliding is arranged on the U-shaped groove 6.

[0041] In practice, the bottom plate 1 is fixed on the floating platform by bolts (which can also be bolts and nuts) at a position where the limiting rod 7 needs to be matched (a through hole is provided on the floating platform at this position for the limiting rod to pass through), and according to the diameter requirement of the limiting rod 7, a suitable limiting and fixing structure is selected and placed in the U-shaped groove 6 for centering adjustment, and after adjustment, it is fixed on the mounting block 5. After fixing, when the floating platform is in a stable state (the floating platform is in a horizontal state, that is, it is not affected by wind and water), the limiting rod 7 is hoisted and inserted into the fixed layer in the water under the centering and limiting action of the limiting and fixing structure 8. After installation of the limiting rod, the limiting and fixing structure cooperates with the limiting rod to limit the horizontal shaking of the floating platform, and when the water level rises and falls, the floating platform can rise and fall along the limiting rod. The embodiment avoids the difficulty of centering and limiting installation of the limiting rod along the limiting hole, and avoids the problem that the floating platform cannot rise and fall when the water level rises and falls or tilts during the rising and falling process, which affects the use or stability of the floating platform. The limiting and fixing structure cooperates with each mounting block to be centrally installed on the limiting hole, which not only makes each stress point bear force uniformly, but also effectively avoids the problem that a single point position cooperates with the limiting rod to bear excessive force, easily slides and moves, and cannot limit the floating platform.

If the threaded rod is matched with the U-shaped groove, it can be arranged on any opposite side, otherwise, it needs to be arranged on both opposite sides.

[0049] ​In practice, when the threaded rod is matched with the U-shaped groove, the reset spring is compressed by applying force to the sleeve rod 17, and the oppositely arranged elastic reset structure 21 is placed between the oppositely arranged mounting blocks, then the pressure is released, the reset spring resets to push the sleeve rod 17 to cooperate with the mounting block 6, after the sleeve rod cooperates with the mounting block in the elastic reset structure, the reset spring is stressed and through the reset action of the reset spring, the two elastic reset structures on each mounting block apply the same or substantially the same force to the hollow ring to make the hollow ring quickly center relative to the limiting hole, so as to further improve the efficiency of the center installation of the limiting rod.
