In the present disclosure, ballast system 14 includes a ballast water device and a movable counterweight device.

In the process of realizing the above, the ballast water device acts on the semi-submersible type floating ship-bearing box 12, water can be taken out from the periphery of the semi-submersible type floating ship-bearing box to ballast water, the operation is convenient and fast, meanwhile, the configuration object can be movably pressed and loaded on the semi-submersible type floating ship-bearing box 12 through the movable counterweight device, so that the configuration object can sink quickly, and the ship navigation efficiency is facilitated.

In other embodiments, ballast system 14 may include ballast water means or movable counterweight means.

In the present disclosure, the traveling system 13 may include an engine and a propeller 24 provided on the semi-submersible floating ship-holding tank 12, and the semi-submersible floating ship-holding tank 12 automatically travels through the engine and the propeller 24. It should be noted that the propellers 24 may be provided on both sides of the semi-submersible floating bearing hull 12 in the traveling direction, so as to facilitate the reciprocating movement of the semi-submersible floating bearing hull 12.

In other embodiments, the traveling system 13 includes a towing trolley, which is provided on the side guide wall 15 and tows the semi-submersible type floating bearing ship box 12.

In the implementation process, the semi-submersible type floating bearing ship box 12 is pulled to run between the two side guide walls 15 through the traction trolley on the side guide walls 15, so that the safe running of the semi-submersible type floating bearing ship box 12 is facilitated; meanwhile, the maintenance cost of the traction trolley is low, and the control of the cost of navigation facilities is facilitated.

It should be noted that the navigation facility described above has at least the following effects:

(1) according to the invention, by dredging the deep navigation channel and adopting the semi-submersible type floating ship loader 11, the problem of navigation obstruction caused by insufficient navigation clearance in the existing cross-navigation bridge area is solved, the bottleneck of inland river navigation is opened, the level of navigation ships is favorably improved, and the advantage of water transportation is fully exerted;

(2) the invention constructs a powerful support of a comprehensive three-dimensional traffic system, adopts a downward-penetrating mode to pass through a height-limited bridge, and saves land resources; compared with an up-span type three-dimensional traffic facility such as a ship lift, the down-through type navigation system has higher navigation efficiency, better safety and more engineering implementation possibility;

(3) the invention can flexibly dispatch and operate according to the navigation ship condition, can operate the navigation brake when no ultrahigh ship exists, does not influence the quick navigation of general ships, and greatly improves the whole navigation efficiency of the height-limited bridge area. The semi-submersible floating ship-carrying box 12 can go to a maintenance position without influencing the normal navigation of a channel in a motor barge traction or self-navigation mode during the maintenance period, so that the non-navigation is realized during the maintenance period;

(4) according to the invention, the side guide wall 15 is arranged to provide lateral limit for the ship, so that the existing bridge is protected, and the safe bridge passing of the ship is ensured.

(5) Meanwhile, according to the arrangement condition of navigation holes in an existing bridge area, the side guide wall 15 can be flexibly adopted to be in a single-hole or multi-hole form, the single-line or multi-line semi-submersible floating ship loader 11 can be arranged, and the adaptability is good.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
