Description

Technical Field

[0002] Currently, due to their advantages such as long-term operation and high controllability, towed underwater vehicles are widely used in marine exploration, seabed exploration, and marine defense. Their deployment and recovery devices play a crucial role in actual operations, directly affecting the vehicle's entry into the water, recovery efficiency, and safety. Existing towed underwater vehicle deployment and recovery devices are generally complex in structure and heavy in weight, posing significant difficulties in transportation, installation, and maintenance. The heavy load and space constraints severely impact their operational flexibility and efficiency. Furthermore, existing deployment and recovery devices require substantial deck space, limiting the placement of other equipment and personnel work, and restricting their application on small and medium-sized vessels with limited onboard space, resulting in poor versatility and adaptability. On the other hand, existing towed underwater vehicle deployment and recovery devices using ship-mounted cranes and rotating methods are prone to collisions with the hull and related equipment during deployment and recovery, especially in harsh sea conditions. This can lead to damage to the vehicle, the hull, and related equipment. The significant collision risk not only increases operating and maintenance costs but may also cause underwater mission interruptions, affecting operational progress. This addresses the current application needs of flexibly deploying underwater towed vehicles on small and medium-sized vessels with limited onboard space.

[0003] Therefore, the key to solving the above-mentioned technical problems lies in developing a stable, reliable, and lightweight cantilevered underwater towed vehicle deployment and recovery device. Utility Model Content

Then, the power distribution control cabinet 8 is welded together with each power distribution control cabinet connector 18 and the power distribution control cabinet mounting frame 112. Finally, the power distribution control cabinet 8 is connected to the geared motor 21 and the drag cable 25 of the cable winch mechanism 2. The assembly of the power distribution control cabinet 8 is then completed and it can be used after assembly.

[0185] The specific steps for using it are:

[0186] Before use, move the assembled device onto the ship's deck 9, then move the device to its installation position on the ship's deck 9, ensuring that the cantilever end above the mounting frame 1 is located outside the ship's deck 9. Next, securely connect the deck surface connector 16 on the mounting frame 1 to the hoisting pad 17 using locking devices. Then, place the pad 17 into the bottom connecting main frame 111 below the mounting bracket assembly 3. Next, open the bracket 33 on one side of the mounting bracket assembly 3, place the underwater towed vehicle 7 on top of the pad 17, and then close and lock the bracket 33.

[0187] When using:

[0188] When deploying the underwater towed vehicle 7: The operator opens one side of the bracket 33 of the support frame assembly 3. Then, the operator moves the underwater towed vehicle 7 to the limit stop block 57 at the front end of the top frame 14 by rotating the hand crank 63 of the adjustment assembly 6 and cooperating with the reduction motor 21 of the cable winch mechanism 2. At this time, the underwater towed vehicle 7 moves to the outside of the ship's side. Then, the cable winch mechanism 2 is controlled by the power distribution control cabinet 8 to continue to lay the cable. After the underwater towed vehicle 7 enters the water, the cable is laid to the correct position to complete the deployment of the underwater towed vehicle 7.

[0189] 2. When towing the underwater towed vehicle 7: After the operator controls the cable winch mechanism 2 to stop releasing the cable through the power distribution control cabinet 8, the operator then controls the power distribution control cabinet 8 to supply power to the underwater towed vehicle 7 through the towing cable 25 and to control it, so that the underwater towed vehicle 7 can perform relevant underwater tasks.

[0190] 3. When recovering the underwater towed vehicle 7: The operator controls the cable winch mechanism 2 to retrieve the cable through the power distribution control cabinet 8. When the cable is retrieved to a certain length, the underwater towed vehicle 7 is hoisted to the front end of the top frame 14. Then, by turning the hand crank 63 of the adjustment component 6 and cooperating with the reduction motor 21 of the cable winch mechanism 2, the underwater towed vehicle 7 can be moved from the outside of the ship to the position of the support frame component 3. After the underwater towed vehicle 7 is in place, the support frame 33 is closed and locked, thus completing the recovery of the underwater towed vehicle 7.

[0191] During the above-mentioned use, the operator turns the hand crank 63, which drives the transmission belt 65 to rotate after the transmission gear set 62 reduces speed and increases torque. This drives the transmission pulley 64, which is meshed with the transmission belt 65, to rotate. The transmission pulley 64 then drives the rotating shaft 52, which is fixedly connected to it, to rotate. The rotating shaft 52 then drives the two drive pulleys 53, which are fixedly connected to it, to move the synchronous belt 56. The two synchronous belts 56 then synchronously drive the guide assembly 4, which is locked to them, to move. This causes the underwater towed vehicle 7, which is suspended on the cable guide pulley 42, to move away from or move away from the work position of the support frame assembly 3.

[0192] Meanwhile, during the entire implementation process described above, the pad 17 is provided so that it can be better flush with the bottom frame 11, which facilitates the placement of the underwater towed vehicle 7 and further supports the underwater towed vehicle 7 and protects its integrity.

[0193] Example 2

[0194] This embodiment 2 is an improved design based on embodiment 1. In this utility model, a pad 17 for supporting the underwater towed vehicle 7 is detachably installed at one end of the mounting frame 1.

[0195] Specifically, the pad 17 can be detachably installed inside one end of the bottom frame 11.

[0196] More specifically, an anti-slip pad is provided on the outer surface of the pad 17 to provide protection and cushioning.

[0197] In this utility model, the pad 17 is a rubber pad made of buffer and protective material, and several rubber protective protrusions with an integral structure are provided on the rubber pad. The rubber protective protrusions are granular or annular protrusions.

[0198] In the utility model, the pad 17 serves as a buffer to protect the bottom of the underwater towing vehicle 7.

[0199] In this embodiment 2, the pad 17 provided by the present invention can be better flush with the bottom frame 11, which facilitates the placement of the underwater towed vehicle 7, so as to further support the underwater towed vehicle 7 and protect its integrity. Other uses are the same as in embodiment 1, and will not be repeated here.

[0200] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model 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.
