Description

Technical Field

[0001] This utility model relates to a deployment and recovery device, specifically a device for deploying and recovering underwater towed vehicles, belonging to the field of underwater towed vehicle deployment and recovery technology. Background Technology

[0002] Generally speaking, with the rapid development of marine scientific research, seabed resource exploration, marine engineering, and marine defense, the application of underwater towed vehicles is becoming increasingly widespread. Underwater towed vehicles (such as underwater tethered robots, underwater acoustic beacons, and underwater towed detectors) are connected to shipboard systems via tow cables and rely on shipboard power supplies for power and control. Compared to autonomous underwater vehicles (AUVs), they offer longer operating times and higher controllability. This advantage of continuous power supply and real-time control enables underwater towed vehicles to stably perform complex underwater detection, data acquisition, and operational tasks for extended periods, making them the preferred equipment in many marine application scenarios.

[0003] Existing underwater towed hull deployment and recovery devices are generally complex in structure, lack versatility, have high operating and maintenance costs, and are prone to failure. Furthermore, these devices occupy significant deck space, especially on small and medium-sized vessels where deck area is limited, further restricting their practical application on such vessels. In addition, the operation of existing devices is complex, requiring substantial manpower at each stage, increasing safety risks and time costs. More importantly, the devices involve numerous cables, and current devices lack corresponding structures to limit or manage these cables. This leads to cable tangling and knots, excessive stretching or breakage, potentially preventing the underwater hull from being recovered properly, or even causing the equipment to sink or drift, posing potential safety risks, especially in complex underwater environments. This not only affects the normal operation of the hull but may also damage the equipment or interrupt the mission. Furthermore, without cable restraint sleeves, the cables may not be stably managed, especially at greater depths or in complex sea conditions. This can make the deployment and recovery of the spacecraft difficult, increase operational complexity, and in short, often cause great inconvenience.

[0004] Given the increasingly widespread use of underwater towed vehicles and the demand for miniaturized, lightweight, flexible deployment and recovery, as well as safe application scenarios on small and medium-sized vessels.

[0005] Therefore, the key to solving the above-mentioned technical problems lies in developing a simple and easy-to-operate device for the deployment and recovery of underwater towed vehicles. Utility Model Content

By adopting a modular design that facilitates disassembly and assembly, the entire device can be hoisted to the deck mounting surface for installation and fixation as a whole, or it can be disassembled into several parts and transported by on-site installation personnel to the relevant positions on the ship's deck for assembly and fixation. This improves installation efficiency, safety, and flexibility, while reducing transportation and labor costs, and at the same time enhancing the maintainability and adaptability of the device.

[0044] The working principle is: Before use, the operator first connects one end of the power distribution cabinet (4) to the external power supply, and then tests the device to ensure that the connection is normal before it is ready for use.

[0045] When deploying an underwater towed vehicle: the operator first places the underwater towed vehicle (7) in the horizontal section (31) of the chute below the fixed frame (1);

[0046] Then, connect one end of the towing cable (25) of the cable winch mechanism (2) to the top of the underwater towed vehicle (7), and then connect the other end of the towing cable (25) to the output cable of the power amplifier box (6).

The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0082] In summary, a more specific embodiment of this utility model is as follows:

[0083] Example 1

[0084] like Figures 1 to 10 The device shown is for the deployment and recovery of underwater towed hulls, including a power distribution cabinet 4, an electrical control cabinet 5, and a power amplifier box 6, and also includes:

[0085] Fixed frame 1, the bottom of fixed frame 1 is connected to the ship deck 8;

[0086] Cable winch mechanism 2, which is detachably installed on one side of the top of the fixed frame 1, is used for the towing of the underwater towing vehicle 7.

[0089] Furthermore, such as Figure 6 and Figure 7 As shown, the fixed frame 1 includes:

[0090] The base frame 11 includes a bottom connecting frame, bottom connecting rods 111 symmetrically connected in the middle of the bottom connecting frame, and uprights 112 vertically connected at the four corners above the bottom connecting frame.

[0091] The top frame 12 includes a top connecting frame and top connecting rods 121 symmetrically connected in the middle of the top connecting frame, and connecting posts 122 vertically connected at the four corners below the top connecting frame. A geared motor mounting rod 123 is also connected between the top connecting rod 121 on one side and the top connecting frame.

[0092] The upper part of each column 112 is connected to the corresponding connecting column 122 and then connected together by locking member 13.

[0093] Specifically, the bottom connecting frame is generally square in shape, and the four connecting rods of the bottom connecting frame are all horizontally provided with base connecting holes at both ends; the bottom connecting rod 111 is horizontally provided with several sliding groove connecting holes that are adapted to and connected to the sliding groove 3; the column 112 is generally a square column structure with open ends and hollow interior, and the upper part of the column 112 is coaxially provided with column connecting holes.

[0095] The connecting column 122 is snapped into the inside of the column 112, and a reinforcing plate is also connected to the connection between the column 112 and the bottom frame.

[0096] Specifically, such as Figure 7 As shown, the bottom connecting frame is also connected to the four corners of the interior foot connector 14, and the interior foot connector 14 is provided with through holes.

[0099] Furthermore, such as Figure 8 and Figure 9 As shown, the cable winch mechanism 2 includes:

[0100] The geared motor 21 is mounted on the geared motor mounting hole of the geared motor mounting rod 123 by fasteners at its lower part.

[0101] The winch bearing housing 22 is installed at the cable winch bearing housing mounting hole on the top connecting rod 121 by fasteners.

[0102] Cable winch 23 is rotatably connected between two winch bearing seats 22 via a connecting shaft 24;

[0103] The towing cable 25 is wrapped around the cable winch 23. One end of the towing cable 25 is connected to the underwater towing vehicle 7, and the other end is connected to the power amplifier box 6.

[0104] One end of the connecting shaft 24 is connected to the output end of the geared motor 21.

[0105] In this utility model, the output cable of the power amplifier box 6 is connected to one end of the towed cable 25 to amplify the power supply and control signals of the towed cable 25 to the underwater towed vehicle 7; one end of the towed cable 25 is fixedly connected to the cable winch 23 to prevent the towed cable 25 from detaching from the cable winch 23.

[0106] Specifically, such as Figure 8 and Figure 9 As shown, the geared motor 21 is an electromagnetic brake geared motor;

[0107] The cable winch 23 also has multiple sets of winch openings 231 circumferentially and coaxially formed on its two discs.

[0108] In this utility model, the geared motor 21 drives the cable winch 23 to rotate through the connecting shaft 24 after the internal reducer reduces speed and increases torque, thereby realizing the cable winding and unwinding action of the cable 25. The cable winch 23 has a winch opening 231 on its disc surface, which reduces the weight of the winch on the one hand, and serves as a safety pin hole when the geared motor 21 is de-energized on the other hand.

[0109] Furthermore, such as Figure 10 As shown, the slide 3 includes:

[0110] The horizontal section 31 of the slide is located above the bottom connecting rod 111;

[0111] The lower slide section 32 is fixedly connected to one end of the horizontal section 31 of the slide.

[0112] Slide connecting ears 33 are symmetrically connected to the lower sides of the horizontal section 31 of the slide;

[0113] Among them, the two opposite sliding groove connecting ears 33 are respectively connected to the corresponding sliding groove connecting holes of the bottom connecting rod 111 through connecting components.

[0114] More specifically, such as Figure 10 As shown, the cross-section of the horizontal section 31 of the chute is U-shaped;

[0115] The slide section 32 has an overall "C" shape, and the cross-section of the slide section 32 has a "U" shape.

[0116] Among them, the outer edges of the upper part of both ends of the horizontal section 31 and the downward section 32 of the slide are connected with rounded edges 34; the downward section 32 and the horizontal section 31 of the slide are integrally molded from fiberglass material.

[0118] Furthermore, such as Figure 1 and Figure 2 As shown, the power distribution cabinet 4 is electrically connected to the power control cabinet 5, the power amplifier box 6, and the geared motor 21, respectively, to provide power.

[0119] The electrical control cabinet 5 is connected to the power amplifier box 6 and the geared motor 21 via signals, and is used to control the operation of the power amplifier box 6 and the geared motor 21.

[0120] In this utility model, the power distribution cabinet 4, the power control cabinet 5, and the power amplifier box 6 are all existing technologies used to achieve their corresponding functions, and are existing structural products that can be purchased on the market.

[0121] The distribution cabinet 4 connects to the power input terminals of the control cabinet 5, the power amplifier box 6, and the geared motor 21 via its output power cable, providing power to these components and enabling power distribution and control signal transmission. The control cabinet 5 connects to the control terminals of the power amplifier box 6 and the geared motor 21 via its output control cable, controlling their operation. The output cable of the power amplifier box 6 connects to the towing cable 25, amplifying the power supply and control signals from the towing cable 25 to the underwater towed vehicle 7. Because the signal and power supply capacity transmitted by the cable will be lost during long-distance underwater towing, the power amplifier box 6 is needed for matching amplification. The distribution cabinet 4 ensures power supply, the control cabinet 5 manages power distribution and regulation through control signals, and the power amplifier box 6 amplifies the control signals to ensure they can drive high-power loads. These components work together to ensure the efficient, stable, and safe operation of the power system, thereby completing various tasks.

[0122] The electrical control cabinet 5 integrates control equipment. The electrical control cabinet 5 can generate control signals and send them to the power amplifier box 6. The power amplifier box 6 amplifies the corresponding control signals and sends them to the underwater towed vehicle 7 through the towing cable 25. After receiving the relevant instructions, the underwater towed vehicle 7 can perform the corresponding tasks.

[0123] Before using the above-mentioned design structure for underwater towed hull deployment and recovery equipment, it needs to be installed as a backup.

[0124] The specific installation steps are as follows: First, the operator welds the pad 9 under the fixed frame 1 to the designated position on the ship deck 8, and then connects and fixes the fixed frame 1 to the ship deck 8 by passing bolts through the inner foot connector 14 and the outer foot connector 15.

[0125] Then, the cable winch mechanism 2 is installed in the corresponding position on the top frame 12 using fastener bolt assemblies;

[0126] Next, the horizontal section 31 of the chute 3 is placed above the bottom connecting rod 111, and the chute connecting hole of the bottom connecting rod 111 is aligned with the corresponding chute connecting lug 33 and then fixed together by bolt assembly, so that the chute outlet of the lower section 32 of the chute extends to the outer side of the ship deck 8.

[0127] Next, the underwater towed vehicle 7 is placed in the horizontal section 31 of the chute inside the structural frame. Then, the connecting part at the top of the underwater towed vehicle 7 is connected to one end of the towing cable 25 of the cable winch mechanism 2.

[0128] Subsequently, the power distribution cabinet 4 is installed on one end of the top of the fixed frame 1 on the other side, the power control cabinet 5 is installed on the top of the fixed frame 1 at one end of the power distribution cabinet 4, and the power amplifier box 6 is installed on one side inside the fixed frame 1.

[0129] Finally, connect the power distribution cabinet 4 to the power control cabinet 5, the power amplifier box 6, and the power input terminal of the geared motor 21 via the output power supply cable; connect the power control cabinet 5 to the power amplifier box 6 and the control terminal of the geared motor 21 via its output control cable, and the assembly of this device is completed. After assembly, it can be used.

[0130] The specific steps for using it are:

[0131] Before use, the operator should first connect one end of the power distribution cabinet 4 to the external power supply, and then test the device to ensure that the connection is normal before keeping it in standby.

[0132] When deploying an underwater towed vehicle: the operator first places the underwater towed vehicle 7 in the horizontal section 31 of the chute below the fixed frame 1;

[0133] Then, connect the top of the underwater towed vehicle 7 to one end of the towing cable 25 of the cable winch mechanism 2, and then connect the other end of the towing cable 25 to the output cable of the power amplifier box 6.

[0134] Next, the operator uses the control cabinet 5 to control the reduction motor 21 to manually push the underwater towed vehicle 7 to the slide section 32 of the chute.

[0135] Finally, the operator controls the geared motor 21 through the electrical control cabinet 5 to drive the cable winch 23 to rotate and lay the towed cable 25 until the underwater towed vehicle 7 enters the water. After laying the cable to the correct position, the deployment function is completed.

[0136] When towing an underwater towed vehicle:

[0137] When the geared motor 21 is stopped, that is, after the cable winch 23 stops laying cables, the power distribution cabinet 4 supplies power to the control cabinet 5 and the power amplifier box 6. Then, the control cabinet 5 and the power amplifier box 6 supply power to the underwater towed vehicle 7 and control it through the towing cable 25, so as to operate the underwater towed vehicle 7 to perform relevant underwater tasks. At this time, the power amplifier box 6 is mainly used to amplify the control signals transmitted by the control cabinet 5 and send the amplified signals to the corresponding systems of the underwater towed vehicle 7.

[0138] When recovering the underwater towed vehicle: The operator controls the geared motor 21 through the electrical control cabinet 5 to drive the cable winch 23 to retrieve the towed cable 25. When a certain length is retrieved, the underwater towed vehicle 7 is aligned with the sliding section 32 of the chute outside the chute 3.
