It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0036] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it may be directly located on the other element or indirectly located on the other element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or indirectly connected to the other element.

Therefore, it should not be understood as a limitation on the present invention.

[0038] In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating relative importance or indicating the number of technical features. In the description of the present utility model, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined. The following is a more detailed description of the specific implementation of the present utility model in conjunction with specific embodiments:

[0039] like Figures 1 to 3 As shown, a capture member 100 provided by an embodiment of the utility model is used to capture water equipment; here, it can be understood that the capture member 100 is used to fix the water equipment with a mother ship such as a navigation equipment body, that is, the mother ship captures the water equipment to achieve the recovery of the water equipment. In addition, the capture member 100 can release the fixed connection with the water equipment, so that the mother ship releases the water equipment to achieve the deployment of the water equipment; of course, the capture member 100 of this embodiment is used to be installed on the water equipment, and can also be installed on other water equipment with a similar structure to the water equipment. At the same time, the capture member 100 of this embodiment can also be used to enable shore equipment such as a deployment and recovery platform to capture the water equipment; the capture member 100 of this embodiment can reduce the damage to the water equipment during the deployment and recovery operation of the water equipment; the following is an explanation through specific implementation methods:

[0040] The capture member 100 of this embodiment includes:

[0041] A capturing body 1, a fixing member 2 and a limiting member 3; the capturing body 1 is used to be arranged on the water equipment, and the capturing body 1 is provided with an insertion end 11 for inserting the capturing net assembly 200; the fixing member 2 is arranged on the insertion end 11, and the fixing member 2 is used to be fixedly connected with the capturing net assembly 200; the limiting member 3 is sleeved on the capturing body 1, and the limiting member 3 is used to abut against the capturing net assembly 200 to prevent the water equipment from colliding with the capturing net assembly 200.

[0042] Here, it can be understood that the capture body 1 is used to be arranged on the water equipment; here, the water equipment is used to drive the capture body 1 to move toward the capture net assembly 200, and the capture body 1 drives the fixing part 2 to move until the insertion end 11 of the capture body 1 is inserted into the capture net assembly 200. In this embodiment, the fixing part 2 can be a hook claw. At this time, the fixing part 2 at the insertion end 11 can hook the capture net assembly 200, thereby realizing the fixed connection between the fixing part 2 and the capture net assembly 200; at the same time, the capture body 1 drives the limiting part 3 to move toward the capture net assembly 200. Since the limiting part 3 is sleeved on the capture body 1, when the insertion end 11 of the capture body 1 is inserted into the capture net assembly 200, the limiting part 3 will abut against the capture net assembly 200, avoiding the capture body 1 from being inserted into the capture net assembly 200 too deep, thereby preventing the water equipment from directly hitting the capture net assembly 200, reducing the possibility of damage to the water equipment.

[0043] The working principle of the capture element 100 of this embodiment is as follows:

[0044] The water equipment has the ability to travel automatically, such as an unmanned boat, etc. This embodiment uses an unmanned boat to illustrate the principle:

[0045] The capturing member 100 is arranged on the unmanned boat, and optionally the capturing member 100 is arranged on the head of the unmanned boat. In addition, the capturing net assembly 200 is arranged on the mother ship or the deployment and recovery platform. The unmanned boat drives the capturing member 100 to move toward the capturing net assembly 200 until it is inserted into the capturing net assembly 200. At this time, the fixing member 2 will hook the capturing net assembly 200 to achieve a fixed connection between the capturing member 100 and the capturing net assembly 200, thereby realizing the recovery operation of the unmanned boat; at the same time, the limiting member 3 will abut against the capturing net assembly 200, preventing the capturing member 100 from continuing to be inserted into the capturing net assembly 200, thereby causing the unmanned boat to collide with the capturing net assembly 200.

[0046] By adopting the above technical solution, a limiter 3 is provided on the capture body 1, and the limiter 3 can limit the water equipment when the water equipment rushes forward toward the capture net assembly 200, so as to prevent the water equipment from rushing forward too violently and colliding with the capture net assembly 200, thereby causing damage to the water equipment and the capture net assembly 200. In this way, the risk of damage to the water equipment is reduced and the safety is improved.

[0047] In one embodiment, the limiting member 3 is coaxially arranged with the capturing body 1 , and the radial dimension of the limiting member 3 is greater than the radial dimension of the mesh 71 of the capturing net assembly 200 .

[0048] Here, it can be understood that the capture body 1 has an axial direction, and the capture body 1 is optionally in the shape of a rod. When the capture body 1 is inserted into the capture net assembly 200, the capture body 1 is inserted into the capture net assembly 200 roughly along its own axial direction; specifically, the capture net assembly 200 is provided with a mesh 71, and the capture body 1 is used to drive the fixing member 2 to be inserted into the mesh 71; the limit member 3 is coaxially arranged with the capture body 1, and when the capture body 1 is inserted into the mesh 71 along its own axial direction, since the radial dimension of the limit member 3 is larger than the radial dimension of the mesh 71, the limit member 3 cannot enter the mesh 71, so that the limit member 3 can abut against the capture net assembly 200, thereby realizing the limiting effect of the limit member 3.

[0049] By adopting the above technical solution, the limiting member 3 can play a limiting role when the capturing body 1 is inserted into the mesh 71 of the capturing net assembly 200 along its own axial direction.

[0050] In one embodiment, the capture member 100 further includes a push rod 4 , which can move along the capture body 1 . When the push rod 4 moves along the capture body 1 , it can drive the fixing member 2 to contract or expand on the capture body 1 .

[0051] Here, it can be understood that the push rod 4 is used to drive the fixing member 2 to retract or expand on the capture body 1; specifically, the push rod 4 includes but is not limited to an automatic push rod 4, the push rod 4 can move along the capture body 1, the push rod 4 is transmission-connected to the fixing member 2, and when the push rod 4 moves along the capture body 1, it can drive the fixing member 2 to retract or expand.

[0052] The working principle of the capture element 100 provided in this embodiment is as follows:

[0053] Recovering the unmanned boat: the push rod 4 drives the fixing member 2 to retract on the capture body 1, so that the capture body 1 can drive the fixing member 2 to insert into the mesh 71 of the capture net assembly 200; after the capture body 1 drives the fixing member 2 to insert into the mesh 71, the push rod 4 drives the fixing member 2 to open on the capture body 1, so that the fixing member 2 hooks the capture net assembly 200 and realizes a fixed connection with the capture net assembly 200, that is, the recovery of the unmanned boat is realized;

[0054] Deploying the unmanned boat: the push rod 4 drives the fixing member 2 to retract on the capturing body 1, and the unmanned boat moves in a direction away from the capturing net assembly 200, so that the capturing member 100 withdraws from the capturing net assembly 200, thereby realizing the deployment of the unmanned boat.

[0055] By adopting the above technical solution, the fixing member 2 can be retracted or expanded under the drive of the push rod 4 to adapt to the deployment or recovery state of the unmanned boat, thereby improving the success rate of the deployment and recovery operation of the unmanned boat.

[0056] In one embodiment, the insertion end 11 is provided with a rotating pin 5, the fixing member 2 is provided on the rotating pin 5 and can rotate around the rotating pin 5 to open or contract relative to the capture body 1, and the fixing member 2 is also provided with a push portion 21, and the push rod 4 can push the push portion 21 to drive the fixing member 2 to contract.

[0057] Here, it can be understood that when the push rod 4 moves on the capture body 1, the push rod 4 can push the pushing portion 21 in a pushing manner, thereby driving the fixing member 2 to rotate around the rotating pin 5, and finally causing the fixing member 2 to shrink relative to the capture body 1.

[0058] By adopting the above technical solution, it is achieved that when the push rod 4 moves on the capture body 1, the fixing member 2 is driven to retract on the capture body 1.

[0059] In one embodiment, an elastic member is provided between the fixing member 2 and the rotating pin 5 , and the elastic member is used to drive the fixing member 2 to open on the capturing body 1 .

[0060] Here, it can be understood that the elastic member provides elastic force for the fixing member 2 to open on the capture body 1; specifically, the elastic member includes but is not limited to a torsion spring, the elastic member connects the fixing member 2 and the rotating pin 5, and the elastic member is used to drive the fixing member 2 to rotate around the rotating pin 5 to achieve opening on the capture body 1.

[0061] The working principle of the capture element 100 of this embodiment is as follows:

[0062] When the unmanned boat drives the capturing member 100 to be inserted into the capturing net assembly 200, the mesh 71 squeezes the fixing member 2 and applies a force greater than the elastic force of the elastic member on the fixing member 2, thereby causing the fixing member 2 to contract. When the fixing member 2 completely enters the mesh 71, the mesh 71 no longer limits the fixing member 2, and the fixing member 2 opens under the elastic force of the elastic member. At this time, the fixing member 2 cannot be detached from the mesh 71, thereby achieving a fixed connection between the capturing member 100 and the capturing net assembly 200.

[0063] By adopting the above technical solution, the elastic member is used to drive the fixing member 2 to open automatically, thereby reducing the possibility of the capture member 100 being separated after being inserted into the capture net assembly 200, and improving the stability of the connection between the two.

[0064] In a second aspect, a water equipment capture and release device is provided, comprising a capture net assembly 200 and a capture member 100 as described above, wherein the capture member 100 is used to be installed on the water equipment, and the capture member 100 is used to be inserted into the capture net assembly 200 to achieve a fixed connection between the water equipment and the capture net assembly 200.

[0065] Here, it can be understood that the capture net assembly 200 can be set on a mother ship or a deployment and recovery platform, so that the water equipment can be recovered to the mother ship or the deployment and recovery platform through the water equipment capture and release device, or deployed from the mother ship or the deployment and recovery platform.

[0066] Specifically, the water equipment can be recovered by moving it toward the mother ship or the deployment and recovery platform, thereby improving the recovery efficiency; similarly, the water equipment can be deployed by moving it in a direction away from the mother ship or the deployment and recovery platform, thereby improving the deployment efficiency.

[0067] By adopting the above technical solution, on the basis of having the advantages of the capture net assembly 200 of the above embodiment, the aquatic equipment capture and release device of this embodiment also has the advantage of improving the efficiency of deploying and recovering aquatic equipment.

[0068] In one embodiment, the capture net assembly 200 includes a frame 6 and a capture net 7 arranged on the frame 6, the frame 6 is provided with a capture opening 61, the capture net 7 is arranged on the capture opening 61, the capture net 7 is provided with a plurality of meshes 71, the size of the meshes 71 matches the size of the capture body 1, so that the capture body 1 can be inserted into the meshes 71 and the fixing member 2 can hook the meshes 71.

[0069] Here, it can be understood that the frame 6 is used to be fixed on the mother ship or the deployment and recovery platform, and the capture net 7 is arranged on the frame 6. The capture net 7 is provided with a plurality of meshes 71, and the capture body 1 can be inserted into any mesh 71, which improves the success rate of the connection between the capture body 1 and the capture net 7.

[0070] Specifically, the size of the mesh 71 matches the size of the capture body 1, that is, the radial size of the mesh 71 is slightly larger than the radial size of the capture body 1 and slightly smaller than the radial size of the stopper 3, so that the capture body 1 can just be inserted into the mesh 71, and the stopper 3 can be blocked outside the mesh 71. For example, the main dimension of the capture net 7 is 1m×1m, and it is made of nylon rope with a diameter of 16mm, and the size of the mesh 71 is 150mm×150mm.

[0071] By adopting the above technical solution, the success rate of connecting the capture body 1 with the capture net 7 is improved.

[0072] In one embodiment, the frame 6 is provided with a plurality of tensioning holes 62 located in the capture opening 61, and an elastic tensioning rope 72 is provided between two adjacent tensioning holes 62. Both ends of the elastic tensioning rope 72 respectively pass through the tensioning holes 62 and are connected to the edge of the capture net 7. The elastic tensioning rope 72 has elastic force and can drive the edge of the capture net 7 to move toward the tensioning hole 62, so that the capture net 7 is tensioned.

[0073] Here, it can be understood that the two ends of the elastic tensioning rope 72 are respectively connected to different parts of the edge of the capture net 7, and are used to move different parts of the edge of the capture net 7 toward the tensioning hole 62, so that the entire capture net 7 is tensioned, thereby expanding the area of ​​the capture net 7, facilitating the capture member 100 to align with the capture net 7, and improving the success rate of docking between the unmanned boat and the capture net assembly 200.

[0074] By adopting the above technical solution, the success rate of docking between the unmanned boat and the capture net assembly 200 is improved.

[0075] In one embodiment, a safety rope 73 is further provided between two adjacent tensioning holes 62 , and two ends of the safety rope 73 respectively pass through the tensioning holes 62 and are connected to the edges of the capture net 7 .

[0076] Here, it can be understood that the safety rope 73 is used to protect the capture net 7 from being pulled off or pulled off; specifically, the safety rope 73 is a rope with relatively small elastic force. When the elastic tensioning rope 72 is broken, the safety rope 73 can also ensure that the capture net 7 has a certain degree of tension, thereby preventing the capture net 7 from falling directly from the frame 6 after the elastic tensioning rope 72 is broken.

[0077] By adopting the above technical solution, the reliability of the capture and release device of the water equipment is improved.

[0078] In a third aspect, a navigation device is provided, including a navigation device body, water equipment and a water equipment capture and release device as described above, wherein a capture net assembly 200 is provided on the navigation device body, and a capture member 100 is provided on the water equipment.

[0079] Here, it can be understood that water equipment includes but is not limited to unmanned boats.

[0080] By adopting the above technical solution, on the basis of having the advantages of the water equipment capture and release device of the above embodiment, the navigation equipment of this embodiment also has the advantage of high efficiency in deploying and recovering water equipment.

[0081] 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 in the protection scope of the present invention.
