[0002] An unmanned surface vessel (UAV) is a typical intelligent platform designed to perform dangerous surface missions and tasks unsuitable for manned vessels. Prior to performing an operation, the UAV must be deployed to a designated area using a hoisting device. After completing its surface operations, the UAV must also be retrieved using a hoisting system.

[0003] In order to reduce the risks of deploying and recovering the unmanned boat body, a safe and reliable deployment and recovery method is needed.

The locking support frame is provided at one end of the unmanned boat body receiving body facing away from the opening. The locking member can rotate about the rotating shaft toward the interior of the receiving space to adjust to a locked position, or rotate toward the outside of the receiving space to adjust to an unlocked position.

[0004] In the existing technology 1, the degree of automation of the locking mechanism is improved, and the risk of deployment and recovery operations is reduced. However, during the deployment and recovery of the unmanned boat body, the unmanned boat body suspended and transferred on the lifting device installed on the mother ship will sway with the wind and waves. This swaying will affect the stability of the unmanned boat body during the deployment process; when the unmanned boat body rises to a certain height, the unmanned boat body will shake and hit the surrounding structures, which may also cause damage to the structure of the unmanned boat body. Utility Model Content

[0005] The purpose of the present utility model is to provide an unmanned boat deployment and recovery system, which, during actual use, can solve the problem in the prior art that the lifting device installed on the mother ship and the unmanned boat body suspended on the lifting device will sway with the wind and waves, and this swaying will affect the stability of the unmanned boat body during the deployment process.

[0008] The anti-sway mechanism includes a fixed part and a telescopic assembly, the fixed part is fixedly connected to the lifting device, the telescopic assembly is slidably installed in the fixed part, a first spring is installed in the fixed part, the telescopic assembly and the fixed part are connected via the first spring, a limiting groove is provided at one end of the telescopic assembly away from the first spring, and a limiting block that cooperates with the limiting groove is provided on the lifting assembly;

[0009] The lifting device is used to drive the lifting assembly to move up and down.

[0010] In some embodiments, the lifting assembly includes a placement frame and a connecting rope, and the limit block is fixedly connected to the placement frame; there are several connecting ropes, and the limit block and the lifting device are connected by the connecting ropes, and the lifting device is used to drive the placement frame up and down through the connecting ropes; the connecting ropes are passed through the fixed part and the telescopic assembly and slide with the fixed part and the telescopic assembly.

[0011] In some embodiments, the placement rack is symmetrically provided with recesses.

[0012] In some embodiments, a first protrusion is provided between the two clearance grooves, and a guiding arc surface is provided on the first protrusion.

[0013] In some embodiments, a baffle is fixedly connected to the placement rack.

[0033] The disclosure below provides many different embodiments or examples for implementing different structures of the embodiments of the present invention. In order to simplify the disclosure of the embodiments of the present invention, the components and settings of specific examples are described below. Of course, these are merely examples and are not intended to limit the embodiments of the present invention. In addition, the embodiments of the present invention may repeat reference numbers and / or reference letters in different examples. Such repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed.

[0034] The embodiments of the present invention are described in detail below with reference to the accompanying drawings:

[0035] See Figure 1-Figure 3 This embodiment discloses an unmanned boat deployment and recovery system, comprising a lifting device provided on a mother ship, an anti-sway mechanism 101, and a lifting assembly 102. The lifting assembly 102 is connected to the lifting device and is used to lift the unmanned boat body. The anti-sway mechanism 101 is installed on the lifting device, and the lifting assembly 102 is slidably installed in the anti-sway mechanism 101.

[0036] The anti-sway mechanism 101 includes a fixed portion 103 and a telescopic assembly 104. The fixed portion 103 is fixedly connected to the lifting device. The telescopic assembly 104 is slidably installed in the fixed portion 103. A first spring 105 is installed in the fixed portion 103. The telescopic assembly 104 and the fixed portion 103 are connected via the first spring 105. A limiting groove is provided at one end of the telescopic assembly 104 away from the first spring 105. A limiting block 107 that cooperates with the limiting groove is provided on the lifting assembly 102.

[0037] The lifting device is used to drive the lifting assembly 102 to move up and down.

[0038] In this embodiment, when the unmanned boat body needs to be recovered, the lifting assembly 102 is first driven downward to below the water surface by the lifting device; then the unmanned boat body is driven to move above the lifting assembly 102, and then the lifting assembly 102 is driven upward by the lifting device to drive the unmanned boat body located above the lifting assembly 102 to rise together, thereby realizing the rapid recovery of the unmanned boat body and further improving the recovery efficiency; in the process of the unmanned boat body moving upward with the lifting assembly 102, when the limit block 107 provided on the lifting assembly 102 moves into the limit groove provided on the telescopic assembly 104, the connection between the unmanned boat body and the lifting device is changed from the original flexible connection of the rope to a rigid connection achieved by counteracting the telescopic assembly 104, thereby effectively reducing the shaking of the unmanned boat body, and the unmanned boat body is more stable following the movement of the lifting device, thereby avoiding structural damage to the unmanned boat body during deployment and recovery. In addition, by connecting the telescopic component 104 to the fixed part 103 through the first spring 105, the telescopic component 104 can move relative to the fixed part 103 under the action of the first spring 105, thereby buffering the upward movement of the unmanned boat body and ensuring that the unmanned boat body is safely lifted and moves smoothly.

[0039] In some embodiments, the lifting assembly 102 includes a placement frame 108 and a connecting rope 109, and the limit block 107 is fixedly connected to the placement frame 108; there are several connecting ropes 109, and the limit block 107 and the lifting device are connected by the connecting rope 109, and the lifting device is used to drive the placement frame 108 to move up and down through the connecting rope 109; the connecting rope 109 is passed through the fixed part 103 and the telescopic assembly 104 and slides with the fixed part 103 and the telescopic assembly 104. When the unmanned boat body needs to be recovered, the connecting rope 109 and the placement frame 108 are first driven downward to below the water surface by the lifting device, and then the unmanned boat body is driven to move above the placement frame 108; at this time, the connecting rope 109, the placement frame 108 and the unmanned boat body located above the placement frame 108 are driven to rise together by the lifting device, thereby realizing the rapid deployment and recovery of the unmanned boat body and further improving the recovery efficiency; in this embodiment, the lifting device includes a hanger for installation on the mother ship and a winding mechanism for driving the connecting rope 109 to drive the placement frame 108 to rise or fall. The winding mechanism is a conventional driving device in the prior art, and its structure and function are not explained here one by one.

[0040] In some embodiments, the placement rack 108 is symmetrically provided with clearance grooves 110. After the unmanned boat body moves to above the placement rack 108, when the placement rack 108 moves upward under the drive of the lifting device, the air cushion installed at the bottom end of the unmanned boat body will enter the clearance groove 110 as the placement rack 108 moves. The cooperation between the clearance groove 110 and the air cushion installed on the unmanned boat body can further limit the position of the unmanned boat, making the unmanned boat more stable during the ascent.

[0041] In some embodiments, a first protrusion 112 is provided between the two clearance grooves 110, and a guide arc surface is provided on the first protrusion 112. The first protrusion 112 can guide the unmanned boat body on the placement rack 108 during the upward movement of the placement rack 108, so that the air cushion installed at the bottom of the unmanned boat body can move into the clearance groove 110 under the guidance of the guide arc surface.

[0042] In some embodiments, a retaining frame 111 is fixedly connected to the placement rack 108. When the lifting device drives the placement rack 108 to move downward below the water surface, the retaining frame 111 also moves below the water surface with the placement rack 108 to avoid blocking the movement of the unmanned boat body; when the placement rack 108 and the unmanned boat body located above the placement rack 108 move upward under the drive of the lifting device, the retaining frame 111 can further limit the unmanned boat body to prevent the unmanned boat body from sliding off the placement rack 108 as the placement rack 108 moves upward.

[0043] In some embodiments, the retaining frame 111 is provided with a drainage groove 114. The provision of the drainage groove 114 can accelerate the drainage efficiency when the placement rack 108 moves upward, and prevent the water remaining on the placement rack 108 from increasing the load of the connecting rope 109 and the lifting device.

[0044] In some embodiments, the telescopic assembly 104 includes a telescopic rod 115 and a second protrusion 116 arranged at the end of the telescopic rod 115 away from the placement rack 108. The telescopic rod 115 and the fixed part 103 are connected through the first spring 105. The connecting rope 109 is passed through the fixed part 103 and the telescopic rod 115 and slides with the fixed part 103 and the telescopic rod 115. The limit groove is arranged on the telescopic rod 115. After the limiting part moves into the limiting groove as the placement rack 108 moves, the original flexible connection of the rope between the unmanned boat body and the lifting device is changed to a rigid connection with the limiting groove, and then the connection is achieved by sliding the telescopic rod 115 installed in the fixed part 103, thereby effectively reducing the shaking of the unmanned boat body, and the unmanned boat body follows the movement of the lifting device more stably; in the process of the telescopic rod 115 moving upward under the drive of the placement rack 108, the first spring 105 connecting the fixed part 103 and the telescopic rod 115 is compressed to buffer the telescopic rod 115, thereby avoiding damage caused by collision between the telescopic rod 115 and the fixed part 103; the second protrusion 116 provided on the telescopic rod 115 can limit the telescopic rod 115 after contacting the fixed part 103, so that neither the telescopic rod 115 nor the placement rack 108 moves. By providing the second protrusion 116, the compression deformation of the first spring 105 can be avoided to be too large, thereby protecting the first spring 105. In this embodiment, the telescopic rod is a conventional telescopic sleeve mechanism in the prior art, and its structure and function will not be described one by one here.

[0045] In some embodiments, a guide plate 113 is fixedly connected to one end of the telescopic rod 115 near the placement frame 108. The guide plate 113 is tilted away from the center line of the telescopic rod 115. The guide plate 113 can guide the limit block 107 so that the limit block 107 can enter the limit groove.

[0046] In some embodiments, the end of the telescopic rod 115 away from the fixing portion 103 is rotatably connected to a locking ring 106, which is threadedly connected to the fixing portion 103. After the unmanned boat body is recovered, the retracted telescopic rod 115 can be fixed by rotating the locking ring 106 so that it is threadedly connected to the fixing portion 103. The locking ring 106 is rotatably mounted on the telescopic rod 115 via a bearing.

[0047] In some embodiments, a limiting platform is provided at one end of the fixing portion 103 close to the telescopic rod 115, and a limiting protrusion is provided at one end of the telescopic rod 115 away from the placement rack 108 for limiting the telescopic rod 115 after cooperating with the limiting platform. A second spring is fixedly connected to the end of the telescopic rod 115 away from the placement rack 108, and a second protrusion 116 is fixedly connected to the end of the telescopic rod 115 away from the placement rack 108. In this embodiment, the telescopic rod 115 moves upward under the drive of the placement rack 108, and the second spring fixedly connected to the telescopic rod 115 moves upward to contact the fixed part 103, so as to buffer the telescopic rod 115 and avoid damage after collision between the telescopic rod 115 and the fixed part 103; by providing the limit platform and the limit protrusion for cooperating with the limit platform, the telescopic rod 115 can be limited to prevent the telescopic rod 115 from falling off from the fixed part 103; the second protrusion 116 provided on the telescopic rod 115 can limit the telescopic rod 115 after contacting the fixed part 103, so that both the telescopic rod 115 and the placement rack 108 stop moving. By providing the second protrusion 116, the compression deformation of the second spring can be avoided from being too large, thereby protecting the second spring.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention.
