Description

Technical Field

[0001] This invention relates to a deployment device, specifically a lightweight underwater vehicle deployment device, belonging to the field of underwater vehicle surface deployment technology. Background Technology

[0002] Generally, the demand for surface deployment of various underwater vehicles (AUVs, underwater drones, and underwater submersibles) is increasing in fields such as underwater exploration, scientific research, resource exploration, and military applications. Deployment scenarios are becoming increasingly complex, ranging from ports and nearshore waters to deep-sea areas. Faced with this high demand and increasingly complex environments, deployment devices require greater flexibility and adaptability. However, existing dedicated deployment devices are typically complex in structure, occupying significant deck space, limiting their application on small vessels, and increasing operating costs and difficulty. Furthermore, most dedicated deployment devices lack versatility, failing to adapt to the deployment needs of different types and sizes of underwater vehicles, thus impacting operational efficiency and flexibility. In addition, existing deployment methods using shipboard cranes and tooling generally have inherent safety hazards and limitations. During use, the slings are prone to slippage and loosening, which not only affects the deployment accuracy of the underwater vehicle but can also lead to the safety risk of equipment falling. On the other hand, this method largely relies on the pre-tensioning and lifting of the crane's wire rope, which is often unsuitable for vessels equipped only with cordless cranes such as telescopic straight / folding booms. Furthermore, after pre-tensioning, the crane's wire rope becomes difficult to maintain a stable and controllable tension during use due to the coupling between the boom's lifting and movement and the wire rope's length. This can easily lead to over-tensioning or under-tensioning, not only compromising deployment stability but also potentially damaging the underwater vehicle and deployment device, increasing equipment maintenance and replacement costs.

[0003] Currently, Chinese utility model patent CN219668433 discloses a simple underwater vehicle deployment device, which mainly includes: a support frame, a release device mounting base, a four-legged sling with a self-locking hook, a flat sling mounting base, a remote-controlled cordless release device, and a flat sling. This device provides poor stability and restraint for the underwater vehicle, and the deployment operation is inconvenient; in short, it is often very inconvenient.

[0004] Therefore, the key to solving the above-mentioned technical problems lies in developing a simple, stable, and reliable lightweight underwater vehicle deployment device. Summary of the Invention

[0005] In view of the many defects and shortcomings of the above-mentioned background technology, the present invention has made improvements and innovations, aiming to provide a simple, stable and reliable lightweight underwater vehicle deployment device. It solves the problems of existing underwater vehicle dedicated deployment devices, such as complex structure, poor versatility, large space occupation on the deck, easy slippage and loosening of the sling when using a ship crane with tooling, and difficulty in stable and controllable pre-tightening and deployment. It can make the pre-tightening constraint of the underwater vehicle stable and controllable during the deployment process. By controlling the remote-controlled cordless release device in the middle, the underwater vehicle deployment function can be completed conveniently and quickly.

[0006] Another objective of this invention is to achieve a simple structure, convenient operation, small footprint, and good versatility, which can meet the needs of complex surface deployment tasks and ensure the safe, efficient, and flexible deployment of underwater vehicles.

The adjusting sleeves (322) are connected to the adjusting component mounting holes by bolt assemblies.

[0026] Each of the support rods (31) is also connected to a traction rope (8), which is located at the lower part of the support rod (31).

[0027] Preferably, the mounting bracket (4) includes:

[0028] The bracket rods (41) are arranged opposite to each other;

[0029] The bracket short rod (42) is symmetrically connected to the two ends between the two bracket long rods (41);

[0030] Bracket connecting seat (43), and the bracket connecting seats (43) are respectively connected above both ends of the bracket short rod (42).

[0031] Preferably, the overall shape of the bracket long rod (41) is a "U" - shaped structure with both ends being low and the middle being high, and upward bending portions are provided at both ends of the bracket long rod (41);

[0032] The overall shape of the bracket short rod (42) is an arc - shaped structure, and the bracket short rod (42) is connected above the inner upper part of the bending portions at the ends of the two bracket long rods (41);

[0033] The bracket connecting seat (43) is obliquely connected above both ends of the bracket short rod (42), and a bracket connecting seat sleeve adapted to be connected with the adapter (5) is provided above the bracket connecting seat (43).

[0034] Preferably, the adapter (5) is an adapter rod or a wire rope buffer;

[0035] The adapter rod includes an adapter rod body in the shape of a circular cylinder and fixing rings connected to both ends of the adapter rod body, and through - holes are formed through both ends of the adapter rod body;

[0036] The wire rope buffer includes buffer connecting plates arranged opposite to each other, two groups of wire rings symmetrically connected between the two buffer connecting plates, and buffer connector heads connected to the outer ends of the buffer connecting plates.

[0037] Preferably, the lifting assembly (2) includes:

[0038] A hand - operated hoist (21), and the upper end of the hand - operated hoist (21) is connected to the shackle (13) below the lifting assembly (1);

[0039] A remote - controlled cordless unhooking device (22), and the non - working end of the remote - controlled cordless unhooking device (22) is connected to the hook of the hand - operated hoist (21);

[0040] A sling (23), and both ends of the sling (23) are connected to the release claws of the remote - controlled cordless unhooking device (22);

[0041] Among them, the remote - controlled cordless unhooking device (22) is connected to the control device through radio - wave signals for control.

[0042] Preferably, a locking portion for limiting the underwater vehicle (7) is further connected to the middle of the sling (23). Among them, one end of the sling (23) is further connected to an anti - falling chain (6), and the other end of the anti - falling chain (6) is connected to the hand - operated hoist (21).

[0043] The working principle is as follows: When working, the operator first wraps the sling (23) around the center of gravity of the underwater vehicle (7) to be deployed, and then puts the two ends of the sling (23) into the release claw below the remote control cordless release device (22), and remotely closes the release claw of the remote control cordless release device (22) through the control device.

[0044] Then, the operator connects the hook of the ship crane (9) to the shackle (13) on top of the device. Then, the operator directs the ship crane (9) to lift the device and the underwater vehicle (7) to be deployed slightly off the deck. Then, the operator uses a lever hoist (21) to lift the underwater vehicle (7) to be deployed until the underwater vehicle (7) is fully pre-tightly attached to the support frame (4) below.

[0045] Next, the operators used a ship crane (9) and a towing rope (8) to move the launch device, along with the pre-tightened and secured underwater vehicle (7), to the desired water surface area for launch.

[0046] Finally, upon reaching the water surface deployment area, the operator controls the release claw of the remote-controlled cordless release device (22) to open through the control equipment. At this time, the two ends of the sling (23) are released, and the underwater vehicle (7) detaches from the sling (23) under the action of gravity and falls downward, completing the water surface deployment function.

[0047] During the above-mentioned use, the sling (23) is also equipped with a fall arrest chain (6). The fall arrest chain (6) is used to prevent the sling (23) from falling into the water with the underwater vehicle (7) after it is deployed. When the underwater vehicle (7) is connected to the release claw of the remote-controlled cordless release device (22) by winding the sling (23), the pre-tightening and stabilization between the support frame (4) and the underwater vehicle (7) can be achieved by adjusting the lever hoist (21). The deployment device together with the pre-tightened and stabilized underwater vehicle (7) can be moved to the water surface deployment area by the ship crane (9). During the hoisting and movement, the traction rope (8) is used to traction and correct the deployment of the underwater vehicle (7). Since the ship crane (9), the deployment device and the underwater vehicle (7) are all rigidly supported and constrained, the collision and shaking of the device and product due to the flexible constraint caused by the swaying of the ship can be effectively avoided.

[0048] The beneficial effects of this invention compared to the prior art are:

[0049] 1. The present invention is simple to operate, stable and reliable, and solves the problems of existing underwater vehicle special delivery devices, such as complex structure, poor versatility, large space occupation on deck surface, easy slippage and loosening of slings, and difficulty in stable and controllable pre-tightening and delivery when using ship crane (9) with tooling delivery method;

[0050] 2. The invention is ingeniously designed. The top is connected to the hoisting equipment, and the bottom is supported by the support frame and slings to firmly constrain the underwater vehicle. The product is pre-tightened by the hand hoist connected in the middle. While eliminating the dependence on the steel wire rope of the ship crane (9), it also ensures that the pre-tightening constraint of the underwater vehicle is stable and controllable during the deployment process. By controlling the remote control cordless release device in the middle, the deployment function of the underwater vehicle can be completed conveniently and quickly.

[0051] 3. The present invention has a simple structure, is easy to operate, occupies little space and has good versatility, and can meet the needs of complex water surface deployment tasks, ensuring the safe, efficient and flexible deployment of underwater vehicles;

[0052] 4. The support component (3) of the present invention is also provided with a traction rope (8). During the hoisting and moving process, the traction rope (8) can be used to traction and correct the deployment of the underwater vehicle (7), which can effectively avoid the collision and shaking of the device and product due to the swaying of the ship due to the flexible constraint.

[0053] 5. The present invention is reasonably designed. A fall protection chain (6) is also installed on the sling (23). The fall protection chain (6) can prevent the sling (23) from falling into the water with the underwater vehicle (7) after the underwater vehicle (7) is deployed.

[0054] 6. The mounting bracket (4) of the present invention can fit perfectly with the underwater vehicle, ensuring the stability of the underwater vehicle during the hoisting process;

[0055] 7. Because the present invention is equipped with a connector (5), it can achieve the purpose of convenient connection and improved buffering. The connection and operation are relatively convenient and reliable, providing a reliable guarantee for the reliable deployment of the underwater vehicle by the entire device.

The adjusting sleeves 322 are sleeved on the support rod 31. Adjusting sleeve connecting holes are opened through both ends of the adjusting sleeves 322. The adjusting sleeves 322 are connected to the adjusting component mounting holes by bolt assemblies.

[0104] Each of the support rods 31 is also connected to a traction rope 8, which is located at the lower part of the support rod 31.

[0105] Furthermore, such as Figure 6 and Figure 13 As shown, the mounting bracket 4 includes:

[0106] The bracket rods 41 are arranged opposite to each other;

[0107] The short bracket rod 42 is symmetrically connected to both ends between two long bracket rods 41;

[0108] The bracket connecting seat 43 is respectively connected above both ends of the short bracket rod 42.

[0110] Specifically, as Figure 13 shown, the long bracket rod 41 is integrally in a "U" - shaped structure with both ends low and the middle high, and upward bending parts are provided at both ends of the long bracket rod 41;

[0114] As Figure 14 shown, the adapter rod includes an adapter rod body in a circular columnar shape and fixing rings connected to both ends of the adapter rod body, and through - holes are provided through both ends of the adapter rod body;

[0115] As Figure 15 and Figure 16 shown, the wire rope buffer includes buffer connecting plates arranged opposite to each other, two groups of wire rings symmetrically connected between the two buffer connecting plates, and buffer connector heads connected to the outer ends of the buffer connecting plates.

[0116] Furthermore, as Figure 9 shown, the lifting component 2 includes:

When the underwater vehicle 7 falls into the water after the sling 23 is released from the remote-controlled cordless release device 22, the anti-fall chain 6 will pull the locking part on the sling 23, and the sling 23 will automatically open under the gravity of the underwater vehicle 7.

[0124] In summary, a more specific embodiment of the present invention is as follows:

[0125] Before using the aforementioned lightweight underwater vehicle launcher, a pre-fabricated underwater vehicle launcher needs to be installed as a backup.

[0126] During installation, the shackle 13 connected to the upper end of the lifting shaft 12 is used to connect with the hook of the marine crane 9; the connecting ring on the lifting shaft 12 is connected to the lifting shaft mounting hole at the opening in the middle of the lifting connector 11 through a bolt assembly; the connecting lugs 111 below the lifting connector 11 are connected to the support frame 4 through four support rods 31 and four adapters 5, wherein the adapters or wire rope buffers are interchangeable and can be used and connected. The four support rods 31 provide rigid support, and the adapters 5 are used to adjust the overall pre-tightening stiffness of the deployment device and to provide a buffering effect during the movement of the underwater vehicle. The adapters can be adjusted according to the actual situation on site. Based on actual usage requirements and working conditions, a wire rope buffer or adapter rod is selected. The telescopic rod 321 and the adjusting sleeve 322 are installed between two adjacent support rods 31 on the left and right sides to adjust the lateral support stiffness of the support rods 31. The lower end of the hoisting shaft 12 is connected to the hook on the top of the lever hoist 21 through the shackle 13. The bottom hook of the lever hoist 21 is connected to the top connection hole of the remote-controlled cordless release device 22 through the shackle. After the flat sling 23 is wrapped around the center of gravity of the underwater vehicle once, its two ends are put into the release claws below the remote-controlled cordless release device 22 to complete the connection of the underwater vehicle 7. After the installation is completed, the work can be carried out.

[0127] During operation, the operator first wraps the sling 23 around the center of gravity of the underwater vehicle 7 to be deployed, then puts both ends of the sling 23 into the release claws below the remote-controlled cordless release device 22, and remotely closes the release claws of the remote-controlled cordless release device 22 through the control equipment.

[0128] Then, the operator connects the hook of the ship crane 9 to the shackle 13 on the top of the device. Then, the operator directs the ship crane 9 to lift the device and the underwater vehicle 7 to be deployed slightly off the deck. Then, the operator uses the lever hoist 21 to lift the underwater vehicle 7 to be deployed until the underwater vehicle 7 is fully pre-tightly attached to the support frame 4 below.

[0129] Next, the operators used a ship crane 9 and a towing rope 8 to move the deployment device, along with the pre-secured underwater vehicle 7, to the desired water surface area for deployment.

[0130] Finally, upon reaching the water surface deployment area, the operator controls the release claw of the remote-controlled cordless release device 22 to open through the control equipment. At this time, both ends of the sling 23 are released, and the underwater vehicle 7 detaches from the sling 23 under the action of gravity and falls downward, completing the water surface deployment function.

[0131] During the above-mentioned use, the sling 23 is also equipped with a fall arrest chain 6, which is used to prevent the sling 23 from falling into the water along with the underwater vehicle 7 after the underwater vehicle 7 is deployed. After the underwater vehicle 7 is connected to the release claw of the remote-controlled cordless release device 22 by winding the sling 23, the pre-tightening and stabilization between the support frame 4 and the underwater vehicle 7 can be achieved by adjusting the lever hoist 21. The deployment device together with the pre-tightened and stabilized underwater vehicle 7 can be moved to the water surface deployment area by the marine crane 9. During the lifting and movement, the traction rope 8 is used to traction and correct the deployment of the underwater vehicle 7. Since the marine crane 9, the deployment device and the underwater vehicle 7 are all rigidly supported and constrained, the collision and shaking of the device and product caused by the swaying of the ship can be effectively avoided.

[0132] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
