The bearing structure comprises a mounting base 11 and a folding platform 12 arranged on the mounting base 11. The mounting base 11 is used to be mounted on a ship platform. The folding platform 12 has two states of folding and unfolding. The folding platform 12 is unfolded to form a guide plane. The guide plane is arranged to be inclined downward along a first horizontal direction. The traction structure comprises a hoisting rope 21. The hoisting rope 21 is arranged to extend along the first horizontal direction. The hoisting rope 21 has two states of stretching and winding. The hoisting rope 21 has a mounting end used to be mounted on the ship platform and a connecting end used to be connected to the underwater equipment A.

[0038] In the ocean deployment and recovery system provided by the present application, the bearing structure and the traction structure are used. When the underwater equipment A, i.e. a submarine marker, is deployed or recovered, the folding platform 12 is first unfolded to form the guide plane on the folding platform 12. The guide plane is arranged to be inclined downward to extend to the underwater. The underwater equipment A is placed on the guide plane. At the same time, the connecting end of the hoisting rope 21 is connected to the underwater equipment A. The deployment or recovery of the underwater equipment A is controlled by the stretching or winding of the hoisting rope 21. It is ensured that the underwater equipment A is not damaged by uncontrolled shaking during sliding. In the embodiment, the underwater equipment A is not lifted by the bearing structure and the traction structure. The constrained movement of the underwater equipment A along the inclined surface is realized by the cooperation of the guide plane and the hoisting rope 21. The shaking of the underwater equipment A during movement is avoided. The stable deployment and recovery of the underwater equipment A are completed.

[0039] It should be noted that the guide plane is arranged downwardly inclined along the first horizontal direction, and the clamping angle between the guide plane and the horizontal plane is not greater than 50°.

[0040] Further, referring to Figure 3 In the embodiment, the mounting base 11 comprises a bracket 111 and a support bracket 112; the bracket 111 is used to be mounted on the hull platform; one end of the support bracket 112 is used to be mounted on the hull platform and is arranged adjacent to the bracket 111 along the first horizontal direction, and the other end is used to extend to the outside of the hull platform; wherein, the upper end surface of the bracket 111 and one end of the support bracket 112 are used to jointly bear the underwater equipment A, and the folding platform 12 is arranged at the other end of the support bracket 112. Before starting to lay or after completing the recovery, in order to facilitate the placement of the underwater equipment A, in the embodiment, the folding platform 12 is arranged at the other end of the support bracket 112 by bearing the underwater equipment A through the bracket 111 and the support bracket 112, when the underwater equipment A such as a submarine marker needs to be laid or recovered, the folding platform 12 is unfolded, the underwater equipment A is pushed from the bracket 111 and one end of the support bracket 112 to the other end of the support bracket and to the guide plane, or is slid from the guide plane to the bracket and one end of the support bracket on the water surface for recovery, after completion, the folding platform 12 is folded, so that the submarine marker is placed on the bracket 111 and the support bracket 112.

[0041] Further, the upper end surfaces of the bracket 111 and the support bracket 112 jointly form a bearing surface, and a limiting groove is recessed on the bearing surface.

In this embodiment, the folding platform is sequentially connected in the first horizontal direction through the plurality of folding plates 121, which avoids occupying space in other directions. At the same time, the relative rotation between the two folding plates 121 is controlled by the first driving device 122, which can individually adjust the rotation angle of each folding plate 121. The angle between the guide plane and the sea surface or the radian of the guide plane itself can be adjusted according to the actual marine conditions, so as to facilitate the laying and recovery of the underwater equipment A.
