Description

Technical Field

[0001] This invention relates to the technical field of navigation equipment, and more specifically, to a boat deployment and recovery device and navigation equipment. Background Technology

[0002] Existing boat deployment and recovery systems consist of a basket and a lifting mechanism connected to the basket. The hook of the lifting device on the mother ship or shore is used to connect to the flexible lifting mechanism, which then lifts the basket. When deploying or recovering a boat, the basket will rise and fall with the waves as it is placed in the water. The lifting device cannot adjust its height in real time to adapt to the rise and fall of the basket, which causes the lifting mechanism between the lifting device and the basket to sag. At this time, the sag lifting mechanism is likely to snag on the boat's deck facilities, hindering the boat from entering or leaving the basket, thus causing deployment and recovery failure. Summary of the Invention

[0003] The purpose of this invention is to provide a boat deployment and retrieval device and navigation equipment to solve the technical problem in the prior art where the lifting components of the boat deployment and retrieval device become loose and droop when it is placed in the water, which hinders the entry and exit of the boat and leads to deployment and retrieval failure.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] In a first aspect, a boat deployment and recovery device is provided, comprising:

[0006] The vessel and boat containment body has a containment space for containing vessels and boats;

[0007] The lifting component includes a first lifting section and a second lifting section. One end of the first lifting section is connected to one side of the vessel housing body, and the other end of the first lifting section is used to connect to a lifting device. One end of the second lifting section is connected to the other side of the vessel housing body, and the other end of the second lifting section is connected to the lifting device.

[0008] An elastic element connects the first lifting section and the second lifting section. An opening communicating with the receiving space is formed between the elastic element, the first lifting section, the second lifting section and the vessel receiving body. The elastic element is used to tension the first lifting section and the second lifting section and drive the first lifting section and the second lifting section to move to widen the opening.

[0009] By adopting the above technical solution, the elastic element can drive the first and second lifting sections to move, thereby widening the opening of the connecting receiving space. This prevents the first and second lifting sections from slacking off due to the undulation of the vessel's receiving body, facilitating the vessel's entry and exit from the receiving space and ensuring the efficiency of vessel deployment and retrieval. Furthermore, the first and second lifting sections can maintain the shape of the opening under the elastic force of the elastic element; that is, the elastic element allows the first and second lifting sections to maintain the shape of the opening even after being disconnected from the lifting device, reducing the impact on the vessel's entry and exit. In one embodiment, the two ends of the elastic element are respectively connected to the first and second lifting sections. When the lifting device lifts the first and second lifting sections, the middle part of the elastic element bends in a direction away from the vessel's receiving body.

[0010] By adopting the above technical solution, the possibility of interference between the elastic component and the ship during bending deformation is reduced.

[0011] In one embodiment, the two ends of the elastic element are connected to the first lifting section and the second lifting section respectively. When the lifting device lowers the first lifting section and the second lifting section, the two ends of the elastic element unfold in a direction away from its midpoint.

[0012] By adopting the above technical solution, the possibility of interference between the elastic component and the boat is reduced.

[0013] In one embodiment, the elastic element includes a sheet or a spring. When the elastic element is a sheet, the two ends of the sheet are respectively connected to the first lifting section and the second lifting section, and the first lifting section and the second lifting section drive the sheet to undergo bending deformation during lifting. When the elastic element is a spring, the two ends of the spring are respectively connected to the first lifting section and the second lifting section, and the first lifting section and the second lifting section drive the spring to undergo compression deformation or bending deformation during lifting.

[0014] By adopting the above technical solution, when the elastic element is compressed and undergoes bending deformation, the opening can expand in the height direction of the ship's main body; when the elastic element is compressed and undergoes expansion and contraction deformation, the opening can expand in the width direction of the ship's main body.

[0015] In one embodiment, the first lifting section and the second lifting section are arranged symmetrically about the central axis of the vessel housing body.

[0016] By adopting the above technical solution, the first and second lifting sections can apply the same force to the vessel's main body during lifting, thereby improving the balance of the vessel's main body during lifting and reducing the possibility of capsizing.

[0017] In one embodiment, the vessel deployment and recovery device includes a plurality of lifting components, which are arranged sequentially at intervals along the length of the vessel receiving body.

[0018] By adopting the above technical solutions, the stability of the vessel's main body during lifting has been improved.

[0019] In one embodiment, the vessel receiving body includes a first vessel receiving body unit and a second vessel receiving body unit symmetrically arranged with respect to the first vessel receiving body unit. A receiving space is formed between the first vessel receiving body unit and the second vessel receiving body unit. The first vessel receiving body unit and the second vessel receiving body unit are rotatably connected by a rotating shaft. The first vessel receiving body unit and the second vessel receiving body unit can rotate towards each other or away from each other around the rotating shaft. The first lifting section is connected to the first vessel receiving body unit, and the second lifting section is connected to the second vessel receiving body unit.

[0020] By adopting the above technical solution, the first and second vessel receiving main units can adapt to clamping vessels of different sizes, while improving the stability when clamping vessels.

[0021] In one embodiment, the boat housing body further includes a bracket, the bracket including a first bracket unit, a second bracket unit, and a rotating shaft rotatably connecting the first bracket unit and the second bracket unit, the first bracket unit being connected to the first boat housing body unit, and the second bracket unit being connected to the second boat housing body unit.

[0022] By adopting the above technical solution, the stability of the second vessel containment main unit and the second vessel containment main unit has been improved.

[0023] In one embodiment, the first vessel housing main unit is provided with a first float, and the second vessel housing main unit is provided with a second float.

[0024] By adopting the above technical solution, the first and second vessel containment main units can be deployed when floating on the water, thus improving the efficiency of the vessel entering the containment space.

[0025] Secondly, a navigation device is provided, including a navigation device body and the aforementioned boat deployment and recovery device, wherein the navigation device body is provided with the lifting device, and the lifting device is used to lift the boat deployment and recovery device.

[0026] By adopting the above technical solution, in addition to the advantages of the boat deployment and recovery device of the above embodiments, the navigation equipment of this embodiment also has the advantage of a high success rate in deploying and recovering boats.

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0038] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating relative importance or the number of technical features. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified. The specific implementation of this invention will be described in more detail below with reference to specific embodiments:

[0039] like Figure 1 and Figure 2 As shown in the figure, an embodiment of the present invention provides a boat deployment and retrieval device for deploying and retrieving boats 2, such as manned or unmanned boats 2. Here, it can be understood that the boat deployment and retrieval device is used to deploy boats 2 into a target water area or retrieve boats 2 from a target water area. Specifically, the boat deployment and retrieval device forms a receiving space, allowing boats 2 to enter and exit the receiving space for deployment and retrieval. In this embodiment, the obstruction to boats 2 entering and exiting the receiving space is small, and the smoothness is high. The following is a detailed description of the specific implementation method:

[0040] The boat deployment and recovery device of this embodiment includes: a boat housing body 1, a lifting component 3, and an elastic component 4;

[0041] The vessel housing body 1 has a housing space for housing the vessel 2. It can be understood that the vessel housing body 1 is used to carry the vessel 2 and move the vessel 2 to the target position. Specifically, the vessel housing body 1 is a hollow structure with a housing space. The shape and size of the housing space match the shape and size of the vessel 2 so that the vessel 2 can be just accommodated in the housing space.

[0042] The lifting component 3 includes a first lifting section 31 and a second lifting section 32. One end of the first lifting section 31 is connected to one side of the vessel housing body 1, and the other end is connected to a lifting device. One end of the second lifting section 32 is connected to the other side of the vessel housing body 1, and the other end is connected to the lifting device. Here, it can be understood that the lifting component 3 is used to connect the vessel housing body 1 and the hook of the lifting device, enabling the lifting device to lift the vessel housing body 1, thereby lifting the vessel 2 within the housing space. Specifically, the lifting component 3 includes a first lifting section 31 and a second lifting section 32, which can be flexible components. The second lifting section 32 can be a flexible lifting cable with high tensile strength, capable of lifting large weights, and easy to store. Alternatively, the first lifting section 31 and the second lifting section 32 can be non-flexible components, such as metal components, or the lifting cable can be soaked in a hard solvent to harden it and give it a certain mechanical strength. The two ends of the first lifting section 31 are respectively connected to one side of the lifting device and the vessel housing 1, and the two ends of the second lifting section 32 are respectively connected to the other side of the lifting device and the vessel housing 1. In this way, the first lifting section 31 and the second lifting section 32 are respectively connected to the opposite sides of the vessel housing 1 to maintain the balance of the vessel housing 1 during lifting.

[0043] The elastic element 4 connects the first lifting section 31 and the second lifting section 32. The elastic element 4, the first lifting section 31, the second lifting section 32 and the vessel receiving body 1 enclose an opening 5 that connects the receiving space. The elastic element 4 is used to tension the first lifting section 31 and the second lifting section 32 and drive the first lifting section 31 and the second lifting section 32 to move to expand the opening 5. Here, it can be understood that the elastic element 4 has elasticity. Connecting the elastic element 4 to the first lifting section 31 and the second lifting section 32 allows the elastic force of the elastic element 4 to drive the first lifting section 31 and the second lifting section 32 to move, thereby maintaining the distance between the first lifting section 31 and the second lifting section 32 within a preset range. Specifically, an opening 5 is formed between the elastic element 4, the first lifting section 31, the second lifting section 32, and the boat receiving body 1. The opening 5 connects to the receiving space. Thus, when the boat 2 is deployed and retrieved, the boat 2 enters and exits the receiving space through the opening 5. To prevent the flexible first lifting section 31 and the second lifting section 32 from sagging during the lifting process and snagging the boat 2, thus preventing the boat 2 from being unable to move, the elastic element 4 is used to ensure the boat 2 can move freely. The vessel 2 can enter and exit through an opening 5. An elastic element 4 connects the first lifting section 31 and the second lifting section 32. The elastic element 4 can drive the first lifting section 31 and the second lifting section 32 to move in opposite directions, thereby increasing the distance between the supports of the first lifting section 31 and the second lifting section 32, that is, increasing the opening 5. In this way, the elastic element 4 provides support and, together with the lifting device, tensions the first lifting section 31 and the second lifting section 32, preventing the first lifting section 31 and the second lifting section 32 from slack and sagging and interfering with the vessel 2's entry and exit from the receiving space. At the same time, the first lifting section 31 and the second lifting section 32 move in opposite directions under the action of the elastic element 4, further increasing the opening 5 for the vessel 2 to enter and further reducing the possibility of the vessel 2 being blocked.

[0044] Please refer to the following: Figure 3 and Figure 4 The working principle of the boat deployment and recovery device provided in this embodiment is as follows:

[0045] Deploying the boat 2: The lifting device is connected to the lifting component 3 via a hook, specifically to the first lifting section 31 and the second lifting section 32. When the boat housing body 1 is suspended above the water surface, the weight of the boat housing body 1 applies a downward vertical force to the first lifting section 31 and the second lifting section 32. The hook, suspending the first lifting section 31 and the second lifting section 32, applies an upward vertical force to them. Thus, the first lifting section 31 and the second lifting section 32 are taut under the combined action of the hook and the boat housing body 1. Section 31 and the second lifting section 32 cause the elastic element 4 to deform and compress or deform and bend. When the boat housing body 1 is placed on the water surface, the boat housing body 1 and the boat 2 in the housing space are both subject to the buoyancy of the water surface. At the same time, the boat housing body 1 and the boat 2 will rise and fall with the waves on the water surface. This may cause the first lifting section 31 and the second lifting section 32 to sag, making it impossible for the boat 2 to sail out of the housing space. At this time, the elastic force of the elastic element 4 drives the sagped first lifting section 31 and the second lifting section 32 to move in opposite directions to widen the opening 5, which is conducive to the boat 2 sailing out of the housing space.

[0046] Recovery of boat 2: The lifting device places the boat housing body 1 on the water surface. At this time, the boat housing body 1 is affected by the waves on the water surface and rises and falls. The first lifting section 31 and the second lifting section 32 will sag. At this time, the elastic force of the elastic element 4 drives the sagped first lifting section 31 and the second lifting section 32 to move in opposite directions to widen the opening 5. At the same time, the hook of the lifting device applies a vertical upward force. In this way, under the action of the hook and the elastic element 4, the opening 5 remains open, which facilitates the boat 2 to enter the housing space.

[0047] By adopting the above technical solution, the elastic element 4 can drive the first lifting section 31 and the second lifting section 32 to move to expand the opening 5 of the connecting reception space. In this way, the first lifting section 31 and the second lifting section 32 are prevented from slacking and sagging due to the undulation of the boat reception body 1, which is conducive to the boat 2 entering and exiting the reception space and ensures the efficiency of the boat 2 deployment and recovery. In addition, the first lifting section 31 and the second lifting section 32 can maintain the shape of the opening 5 under the elastic force of the elastic element 4. That is, the elastic element 4 can make the first lifting section 31 and the second lifting section 32 maintain the shape of the opening 5 even after they are disconnected from the lifting device, reducing the impact on the boat 2 entering and exiting.

[0048] In one embodiment, the end of the first lifting section 31 facing away from the vessel housing body 1 is connected to the end of the second lifting section 32 facing away from the vessel housing body 1. The first lifting section 31 and the second lifting section 32 are used to connect to the same lifting device, so that when the lifting device lifts the first lifting section 31 and the second lifting section 32, the distance between the first lifting section 31 and the second lifting section 32 gradually increases from the lifting device toward the vessel housing body 1.

[0049] By adopting the above technical solution, the opening 5 gradually expands from the lifting device to the main body 1 of the vessel, which helps to increase the degree of expansion of the opening 5 and facilitates the entry and exit of the vessel 2 into the receiving space.

[0050] In one embodiment, the end of the first lifting section 31 facing away from the vessel receiving body 1 and the end of the second lifting section 32 facing away from the vessel receiving body 1 are arranged separately. The first lifting section 31 and the second lifting section 32 are respectively connected to two lifting devices, or the first lifting section 31 and the second lifting section 32 are respectively connected to two hooks of the lifting device, so that when the lifting device lifts the first lifting section 31 and the second lifting section 32, the shape of the opening 5 is square, rectangular or trapezoidal.

[0051] By adopting the above technical solution, the expansion degree of opening 5 is improved, further reducing the possibility of lifting component 3 blocking the entry and exit of boat 2.

[0052] In one embodiment, the two ends of the elastic member 4 are connected to the first lifting section 31 and the second lifting section 32 respectively. When the lifting device lifts the first lifting section 31 and the second lifting section 32, the middle part of the elastic member 4 bends in a direction away from the main body of the vessel housing 1.

[0053] Here, it can be understood that the elastic element 4 is used to enclose the opening 5 with the first lifting section 31, the second lifting section 32, and the boat housing body 1. In order to enlarge the size of the opening 5, when the lifting device lifts the first lifting section 31 and the second lifting section 32, the bending deformation direction of the elastic element 4 is set to be away from the direction of the boat housing body 1. That is, when the elastic element 4 is subjected to the force of the first lifting section 31 and the second lifting section 32 and undergoes bending deformation, the elastic element 4 bends in the direction away from the boat housing body 1, so that the elastic element 4 arches upward, enlarging the size of the opening 5, and avoiding interference with the boat 2 when the elastic element 4 undergoes bending deformation under pressure.

[0054] By adopting the above technical solution, the possibility of interference between the elastic element 4 and the boat 2 during bending deformation is reduced.

[0055] In one embodiment, the two ends of the elastic member 4 are connected to the first lifting section 31 and the second lifting section 32 respectively. When the lifting device lowers the first lifting section 31 and the second lifting section 32, the two ends of the elastic member 4 unfold in a direction away from its own midpoint.

[0056] Here, it can be understood that the elastic element 4 is used to enclose the opening 5 with the first lifting section 31, the second lifting section 32 and the main body of the boat housing 1. In order to enlarge the size of the opening 5, when the lifting device lowers the first lifting section 31 and the second lifting section 32, the elongation deformation direction of the elastic element 4 is set to the direction away from its own midpoint. That is, when the first lifting section 31 and the second lifting section 32 reduce the force applied to the elastic element 4 and cause the elastic element 4 to elongate, the elastic element 4 unfolds along the direction away from its own midpoint, thereby enlarging the size of the opening 5 and avoiding interference between the elastic element 4 and the boat 2.

[0057] By adopting the above technical solution, the possibility of interference between the elastic element 4 and the boat 2 is reduced.

[0058] In one embodiment, the elastic element 4 includes a sheet or a spring. When the elastic element 4 is a sheet, the two ends of the sheet are respectively connected to the first lifting section 31 and the second lifting section 32. The first lifting section 31 and the second lifting section 32 drive the sheet to bend during lifting. When the elastic element 4 is a spring, the two ends of the spring are respectively connected to the first lifting section 31 and the second lifting section 32. The first lifting section 31 and the second lifting section 32 drive the spring to compress or bend during lifting.

[0059] Here, it can be understood that when the elastic element 4 is a spring sheet, the spring sheet has a preset length. When the spring sheet is subjected to a force toward the center of the spring sheet at both ends, the spring sheet will bend and deform and has a tendency to return to its original shape, that is, the spring sheet has elasticity. In this embodiment, the first lifting section 31 and the second lifting section 32 apply a force toward the center of the spring sheet during lifting, which causes the spring sheet to bend and deform under pressure.

[0060] When the elastic element 4 is a spring, the spring can undergo bending deformation or extension deformation. In this embodiment, the first lifting section 31 and the second lifting section 32 apply a force toward the center of the spring during lifting, which can cause the spring to undergo bending deformation or extension deformation.

[0061] By adopting the above technical solution, when the elastic element 4 is compressed and undergoes bending deformation, the opening 5 can expand in the height direction of the boat receiving body 1; when the elastic element 4 is compressed and undergoes expansion and contraction deformation, the opening 5 can expand in the width direction of the boat receiving body 1.

[0062] In one embodiment, the first lifting section 31 and the second lifting section 32 are arranged symmetrically about the central axis of the vessel housing body 1.

[0063] Here, it can be understood that the first lifting section 31 and the second lifting section 32 are of equal length and are arranged symmetrically.

[0064] By adopting the above technical solution, the first lifting section 31 and the second lifting section 32 can apply the same force to the vessel housing body 1 during lifting, thereby improving the balance of the vessel housing body 1 during lifting and reducing the possibility of capsizing.

[0065] In one embodiment, the boat deployment and recovery device includes multiple lifting components 3, which are arranged sequentially at intervals along the length of the boat receiving body 1.

[0066] Here, it is understood that multiple lifting components 3 can be connected to the same lifting device.

[0067] By adopting the above technical solution, the stability of the vessel receiving body 1 during lifting is improved.

[0068] In one embodiment, the boat receiving body 1 includes a first boat receiving body unit 11 and a second boat receiving body unit 12 symmetrically arranged with respect to the first boat receiving body unit 11. A receiving space is formed between the first boat receiving body unit 11 and the second boat receiving body unit 12. The first boat receiving body unit 11 and the second boat receiving body unit 12 are rotatably connected by a rotating shaft 13. The first boat receiving body unit 11 and the second boat receiving body unit 12 can rotate towards each other or away from each other around the rotating shaft 13. A first lifting section 31 is connected to the first boat receiving body unit 11, and a second lifting section 32 is connected to the second boat receiving body unit 12.

[0069] Here, it can be understood that, in order to accommodate and fix boats 2 of different sizes, the boat accommodating body 1 is configured to include a first boat accommodating body unit 11 and a second boat accommodating body unit 12 symmetrically arranged with respect to the first boat accommodating body unit 11. An accommodating space is formed between the first boat accommodating body unit 11 and the second boat accommodating body unit 12. The first boat accommodating body unit 11 and the second boat accommodating body unit 12 are rotatably connected by a rotating shaft 13. The first boat accommodating body unit 11 and the second boat accommodating body unit 12 can rotate towards each other around the rotating shaft 13 to reduce the accommodating space, or the first boat accommodating body unit 11 and the second boat accommodating body unit 12 can rotate away from each other around the rotating shaft 13 to expand the accommodating space.

[0070] Specifically, the first lifting section 31 is connected to the first vessel housing unit 11, and the second lifting section 32 is connected to the second vessel housing unit 12. When the first lifting section 31 and the second lifting section 32 lower the first vessel housing unit 11 and the second vessel housing unit 12 into the water, the buoyancy of the water surface drives the first vessel housing unit 11 and the second vessel housing unit 12 to rotate in opposite directions around the rotation axis 13. At this time, the housing space is expanded, making it easier for the vessel 2 to enter the housing space. When the first lifting section 31 and the second lifting section 32 lower the first vessel housing unit 11 and the second vessel housing unit 12 into the water, the buoyancy of the water surface drives the first vessel housing unit 11 and the second vessel housing unit 12 to rotate in opposite directions around the rotation axis 13. At this time, the housing space is expanded, making it easier for the vessel 2 to enter the housing space. When the main body unit 12 is lifted, the first lifting section 31 and the second lifting section 32 apply tension to the first boat receiving main body unit 11 and the second boat receiving main body unit 12 respectively, driving the first boat receiving main body unit 11 and the second boat receiving main body unit 12 to rotate towards each other around the rotation axis 13 until the first boat receiving main body unit 11 and the second boat receiving main body unit 12 clamp the boat 2 located in the receiving space. In this way, the first boat receiving main body unit 11 and the second boat receiving main body unit 12 can adapt to clamping boats 2 of different sizes, and at the same time improve the stability when clamping the boat 2.

[0071] It needs to be further explained that the axis of the rotating shaft 13 is parallel to the length direction of the boat housing body 1, so that the first boat housing body unit 11 and the second boat housing body unit 12 can be folded or unfolded in the width direction of the boat housing body 1.

[0072] By adopting the above technical solution, the first boat receiving main unit 11 and the second boat receiving main unit 12 can adapt to clamping boats 2 of different sizes, and at the same time improve the stability when clamping boats 2.

[0073] In one embodiment, the boat housing body 1 further includes a bracket 6, which includes a first bracket unit 61, a second bracket unit 62, and a rotating shaft 13 rotatably connecting the first bracket unit 61 and the second bracket unit 62. The first bracket unit 61 is connected to the first boat housing body 11, and the second bracket unit 62 is connected to the second boat housing body 12.

[0074] Here, it can be understood that the bracket 6 is used to support and fix the first vessel housing main unit 11 and the second vessel housing main unit 12;

[0075] Specifically, the bracket 6 includes a first bracket unit 61, a second bracket unit 62, and a rotating shaft 13 rotatably connecting the first bracket unit 61 and the second bracket unit 62. The first bracket unit 61 is connected to the first boat receiving main body unit 11, and the second bracket unit 62 is connected to the second boat receiving main body unit 12. In this way, the first bracket unit 61 and the first boat receiving main body unit 11 can rotate synchronously around the rotating shaft 13. Similarly, the second bracket unit 62 and the second boat receiving main body unit 12 can rotate synchronously around the rotating shaft 13.

[0076] By adopting the above technical solution, the stability of the second vessel housing main unit 12 and the second vessel housing main unit 12 is improved.

[0077] In one embodiment, the bracket 6 further includes an angle limiting structure 63, on which the rotating shaft 13 is disposed. The angle limiting structure 63 is used to limit the rotation range of the first bracket unit 61 and the second bracket unit 62, so as to avoid excessive pressure on the boat 2 due to excessive rotation angle of the first bracket unit 61 and the second bracket unit 62, thereby causing damage to the boat 2.

[0078] In one embodiment, the first vessel housing main unit 11 is provided with a first float 71, and the second vessel housing main unit 12 is provided with a second float 72.

[0079] Here, it can be understood that the first float 71 is used to provide buoyancy to the first vessel housing unit 11, so that the first vessel housing unit 11 can float on the water surface. The first float 71 can be provided at the bottom or side of the first vessel housing unit 11. The first float 71 provided at the side can also act as a buffer. Similarly, the second float 72 is used to provide buoyancy to the second vessel housing unit 12, so that the second vessel housing unit 12 can float on the water surface. The second float 72 can be provided at the bottom or side of the second vessel housing unit 12. The second float 72 provided at the side can also act as a buffer.

[0080] Specifically, the buoyancy of the first float 71 and the second float 72 can drive the first boat housing main unit 11 and the second boat housing main unit 12 to rotate in opposite directions around the rotation axis 13, so that the first boat housing main unit 11 and the second boat housing main unit 12 can unfold outward when floating on the water surface, which facilitates the entry of the boat 2.

[0081] By adopting the above technical solution, the first vessel accommodating main unit 11 and the second vessel accommodating main unit 12 can be deployed when floating on the water surface, thereby improving the efficiency of the vessel 2 entering the accommodating space.

[0082] Secondly, a navigation device is provided, including a navigation device body and the aforementioned boat deployment and recovery device. The navigation device body is equipped with a lifting device, and the hook of the lifting device is used to lift the boat deployment and recovery device.

[0083] Here, it can be understood that the main body of the navigation equipment can be a manned or unmanned vessel. A lifting device is provided on the main body of the navigation equipment. The lifting device is used to connect with the lifting component 3. The lifting device is used to lift the vessel deployment and recovery device to realize the deployment and recovery of the vessel 2.

[0084] By adopting the above technical solution, in addition to the advantages of the boat deployment and recovery device of the above embodiment, the navigation equipment of this embodiment also has the advantage of a high success rate in deploying and recovering boats 2.

[0085] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
