DETAILED DESCRIPTION OF THE EMBODIMENTS

(21) For further illustrating the invention, experiments detailing a floating and mobile carrying platform device are described below.

(22) FIGS. 1, 2 and 3 illustrate a floating and mobile carrying platform device in a first embodiment. The platform device comprises a column-type buoyancy pier 2, a semi-submersible tower 4, a load-bearing deck trunk 1, a slideway 3, rest piers 1a, a stabilizer fin 2b, a connection member 5 and a console 4d. The load-bearing deck trunk 1 is of a box structure, in which cross rib plates 1c are used as a framework supporting a top plate 1e, a bottom plate 1f and side plates 1g. Thus, the load-bearing deck trunk is a main carrier of a to-be-carried structure 6 under different working conditions. The top plate 1e of the deck trunk is provided with rest piers 1a, the slideway 3, and water holes 1b. The bottom plate 1f is also provided with the water holes 1b. The slideway 3 can be utilized as a temporary bearing member during specific working, and then the rest piers 1a jack up to bear the weight, which is conducive to improving the carrying stability. The truss type connection member 5 adopts a round pipe structure and connects the load-bearing deck trunk 1 and the semi-submersible tower 4, it is made of light-weight material. The connection member ensures the continuity and the structural strength of the entire structure; the column-type buoyance piers 2 and the semi-submersible tower 4 are in periphery symmetrical distribution centered on the load-bearing deck trunk 1 and are used for providing a buoyancy for the entire platform so that the platform device can complete various operations. The section forms of the column-type buoyance piers 2 are beneficial to reducing towing resistance, the inflation valve 4g are disposed outside the semi-submersible tower 4 and used for connecting an external aerating source, and the entire tower can ensure the buoyancy and the primary stability of the platform device.

(23) FIGS. 4, 5 and 6 illustrate specific forms of the column-type buoyance piers 2 which are of a wing shape or a spindle type. FIG. 4 shows a wing-shaped section, FIG. 5 shows a spindle-type section on which the drain valves 2a, the air valves 2c and the stabilizer fin 2b are provided. The air valves 2c are disposed on the upper parts of the column-type buoyance piers 2 and used for pumping in compressed air so that the ballast water in the piers is discharged and the platform device upwardly floats. The drain valves 2a and the air valves 2c are controlled by the console 4d; the stabilizer fin 2b is of a wing shape, and a lift force generated in the towing process ensures the towing stability of the platform device.

(24) FIGS. 7, 8 and 9 illustrate an internal structure of the load-bearing deck trunk 1. A plurality of drainage holes 1b is disposed on the upper and lower surfaces of the load-bearing deck trunk 1 ensuring the internal water flow is smooth. Meanwhile, the cross rib plates 1c are provided with the lightening holes 1h and the vent holes 1i, so the entire structure is light and safe. Furthermore, the compressed air pipelines 4f are disposed in the lightening holes 1h and used for charging compressed air from the semi-submersible tower 4 to the column-type buoyancy piers 2.

The console 4d controls the drain valves 2a and the air valves 2c to close, then the platform is towed right below the carrying structure 6 or the carrying structure 6 is towed right above the platform through a cable 7 connecting to the tugboat. The console 4d controls the drain valves 2a and the air valves 2c to open, and compressed air prestored in the air tanks 4e is pumped into the air valves 2c via the compressed air pipelines 4f.
