Wherein, exemplarily, the mooring device 23 comprises a plurality of sets of fixed mooring hooks arranged at intervals in the horizontal and height direction on the inner wall of the ship-receiving box 17. Alternatively, in the case of a large water level change, the mooring means 23 may comprise a plurality of sets of floating mooring columns arranged at horizontally spaced intervals on the inner wall of the ship receiving box 17. The multiple groups of fixed ship-tying hooks or floating ship-tying columns are respectively connected with the ship, so that the connection stability of the ship and the ship-holding box body 17 is facilitated, meanwhile, the ship is kept static relative to the ship-holding box body 17, and the semi-submersible floating ship-holding box 12 is facilitated to stably carry the ship through the cross-navigation bridge 10 b.
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) the utility model solves the problem of navigation obstruction caused by insufficient navigation clearance in the existing cross-navigation bridge area by dredging the deep navigation channel and adopting the semi-submersible type floating ship loader 11, and breaks through the bottleneck of inland river navigation, thereby being beneficial to improving the navigation ship grade and fully exerting the advantage of water transportation;
(2) the utility model constructs a powerful support of a comprehensive three-dimensional traffic system, adopts a downward-wearing 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 utility model discloses can carry out nimble dispatch operation according to the navigation boats and ships condition, can open the floodgate operation when no super high boats and ships, do not influence the quick navigation of general boats and ships, improve the whole navigation efficiency in limit for height bridge district greatly. 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) the utility model discloses a set up the side and lead wall 15 and provide boats and ships side direction spacing, protect existing bridge, ensured boats and ships safety gap bridge.
(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.
