[0041] As Figures 1 to 16 shown, the preferred embodiment of the submersible vehicle launching ship of the present application includes a ship body 1, a first support structure 21, a travelling crane 3, a second support structure 23 and a second guide rail 24:

[0042] Each side of the ship body 1 is provided with a first support structure 21, and each first support structure 21 is provided with a first guide rail 22 arranged along the length direction of the ship body 1; the first support structure 21 is a torsion box structure to ensure that it has sufficient strength and rigidity;

[0043] The travelling crane 3 includes a travelling beam 31 and a lifting mechanism 32 arranged on the travelling beam 31, the lifting mechanism 32 is used to lift or lower the container pallet 4 on the ship body 1 for accommodating the submersible vehicle 7, and the two ends of the travelling beam 31 are arranged on each first guide rail 22; there are various ways for the travelling beam 31 to travel on the first guide rail 22, such as arranging the first guide rail 22 as a rack, arranging a driving gear on the travelling beam 31 to engage with the rack, and the length direction of the travelling beam 31 is parallel to the width direction of the ship body 1; the lifting mechanism 32 includes a mounting seat connected to the travelling beam 31, a driving device 44 arranged on the mounting seat for driving the mounting seat to move along the length direction of the travelling beam 31 at one end of the travelling beam 31, and a pulley 322 mechanism and a winding device 322 arranged on the mounting seat for lifting or lowering the container pallet 4;

[0044] Each first support structure 21 is hingedly connected with a second support structure 23 at one end in the length direction of the hull 1, and each second support structure 23 is arranged in superposition with the corresponding first support structure 21; the second support structure 23 is a torsion-resistant box structure, and the profile of the second support structure 23 in the width direction of the ship is a triangular structure; rotating the second support structure 23 can make the second support structure 23 and the first support structure 21 fold along the length direction of the hull 1;

[0045] Each second support structure 23 is provided with a second guide rail 24; rotating each second support structure 23 can make each second support structure 23 protrude to the outside of the hull 1, and make each second guide rail 24 respectively butt joint with the corresponding first guide rail 22, so that the walking beam 31 can walk from each second guide rail 24 to each first guide rail 22. When it is needed to deploy the submersible 7 into the water, first rotate each second support structure 23 to make each second support structure 23 protrude to the outside of the hull 1, and make each second guide rail 24 respectively butt joint with the corresponding first guide rail 22; thereafter, the container pallet 4 is lifted by the lifting mechanism 32, the walking beam 31 walks from each second guide rail 24 to each first guide rail 22, and then the container pallet 4 is lowered by the lifting mechanism 32 to deploy the container pallet 4 into the water, realizing the deployment of the submersible 7; the operation of the crane 3 is simple and convenient, and the deployment efficiency of the submersible 7 is improved; moreover, after the deployment of the submersible 7 is completed, each second support structure is rotated to be in superposition with the corresponding first support structure, which can avoid the center of gravity of the hull 1 from deviating due to the protrusion of the second support structure to the outside of the hull 1, and ensure the stability of the hull 1 during navigation.

[0046] In the embodiment, each second support structure 23 is arranged in superposition with the corresponding first support structure 21 at one end away from the center line of the hull 1. Specifically, the first support structure 21 and the second support structure 23 are hingedly connected in a hinge structure, and the hinge shaft 55 is located at the intersection of one end of the first support structure 21 away from the center of the hull 1 and the stern end; in this way, when the second support structure 23 is rotated, the second support structure 23 will not be placed in the area between the two first support structures 21, and the area of the deck of the hull 1 between the two first support structures 21 can be fully utilized; the first support structure 21 and the crane 3 only occupy the side and the top space of the ship, maximizing the cargo-carrying and operation deck area, and realizing the full utilization of the space of the hull 1.

[0047] To avoid the influence of the deployment or recovery of the submersible 7 on the driver's view of the ship body 1, in the embodiment, each second support structure 23 is arranged at the stern of the ship body 1, and each first support structure 21 is connected with a driving mechanism 5 for driving the corresponding second support structure 23 to rotate, at an end away from the center line of the ship body 1.
