Description

Technical Field

[0001] The present invention relates to the technical field of deployment and recovery of mobile platforms, and more specifically, to a deployment and recovery system for a mobile platform and a deployment method for a mobile platform. Background Art

[0002] The way in which existing mobile platforms such as underwater detection equipment perform tasks is as follows: a mother ship carries the underwater detection equipment to the distant sea to perform tasks. When the mother ship arrives at the target sea area, the underwater detection equipment is deployed to the target location. After the underwater detection equipment completes the detection task, the mother ship recovers the underwater detection equipment to the mother ship.

[0003] However, there are two traditional methods of deployment and recovery. One is to guide the underwater detection equipment into a deployment and recovery cage, and then move the deployment and recovery cage between the water surface and the mother ship to complete the deployment and recovery of the underwater detection equipment. Since the volume of the deployment and recovery cage needs to adapt to the volume of the underwater detection equipment, the deployment and recovery cage occupies too much space on the mother ship; the second is to dock with the underwater detection equipment through lifting equipment. This method has the problem of high connection difficulty. When recovering the underwater detection equipment in poor water conditions, it is difficult for the lifting equipment to align and connect with the underwater detection equipment, resulting in a long recovery time. Summary of the invention

[0044] like Figures 1 to 3 As shown, a mobile platform deployment and recovery system provided by an embodiment of the present invention includes: a mother ship 1 and a mobile platform 2 placed on the mother ship 1. In this embodiment, the mobile platform 2 includes but is not limited to underwater detection equipment or unmanned boats. The mother ship 1 is provided with a hoisting device 11, a capture device 12 and a decoupling device 13. The capture device 12 and the decoupling device 13 are arranged on the hoisting device 11; the mobile platform 2 is provided with a hook device 21 and a traction device 24. The hook device 21 is used to dock with the hoisting device 11, the decoupling device 13 is used to release the connection between the hoisting device 11 and the hook device 21, and the traction device 24 is used to shoot a traction rope 244 toward the water surface;

[0045] like Figure 4 and Figure 5 As shown, when the mobile platform 2 is deployed from the mother ship 1 to the water surface, the hook device 21 docks with the lifting device 11, the lifting device 11 transfers the mobile platform 2 from the mother ship 1 to the water surface, and the unhooking device 13 releases the connection between the lifting device 11 and the hook device 21, releasing the mobile platform 2;

[0047] The beneficial effects of the mobile platform deployment and recovery system provided in this embodiment are:

[0048] Firstly, by arranging a hoisting device 11 on the mother ship 1 and connecting it to the mobile platform 2 by hoisting, there is no need to arrange a bulky deployment and recovery cage, thus saving space on the mother ship 1 and improving the load capacity of the mother ship 1; secondly, by arranging a decoupling device 13, the steps of deploying the mobile platform 2 are simplified and the difficulty of the deployment operation is reduced; finally, by arranging a capture device 12 on the hoisting device 11 to cooperate with the traction rope 244 of the traction device 24 arranged on the mobile platform 2, the traction rope 244 guides the hook device 21 of the mobile platform 2 to dock with the capture device 12, thereby reducing the difficulty of recovering the mobile platform 2 and shortening the recovery time.

[0049] Please refer again Figure 1 In one embodiment, the hoisting device 11 includes a hoisting arm 111, a driving member 112, a lifting member 113 and a hook body 114; the hoisting arm 111 is rotatably connected to the mother ship 1, and the hoisting arm 111 can be flipped between the inside and the outside of the mother ship 1, and is used to transfer the mobile platform 2 connected to the hoisting arm 111 between the inside and the outside of the mother ship 1; the driving member 112 drives the hoisting arm 111 to flip, and the driving member 112 includes but is not limited to a hydraulic cylinder; the lifting member 113 is arranged at the movable end of the hoisting arm 111, and the lifting member 113 is retractable, and the lifting member 113 includes but is not limited to a hydraulic winch; the hook body 114 is arranged on the lifting member 113, and is used to connect with the hook device 21 on the mobile platform 2.
