Description

Technical Field

[0001] This utility model relates to the technical field of underwater equipment recovery devices, specifically to a float-rope silo type underwater acoustic recovery device. Background Technology

[0002] When carrying out engineering projects such as underwater geological exploration and hydro-meteorological exploration, it is often necessary to deploy various underwater equipment, devices and systems, and periodically retrieve these underwater equipment, devices and systems onto ships to collect data.

[0003] There are two existing technical solutions for the recovery of underwater equipment: Option 1: Various underwater equipment, devices, and systems are connected to buoys via cables, floating on the water's surface. When recovering underwater equipment, the buoys on the surface are located first, then the cables are pulled to retrieve the equipment onto the vessel. This technical solution makes the buoys and cables connecting the underwater equipment easily snagged by the vessel, potentially leading to the loss of the underwater equipment, devices, and systems.

[0004] Option 2: Employing acoustic recovery devices fixed to various underwater equipment, devices, and systems, or deployed on the seabed. The disadvantage of this approach is that varying underwater geological conditions, including slopes and channels, can easily cause the acoustic recovery device to tilt or overturn, thus affecting its success rate. Utility Model Content

[0005] The purpose of this invention is to provide a float-rope underwater acoustic recovery device to solve the technical problems in the prior art where underwater equipment is easily damaged or lost and the acoustic recovery device has a relatively low success rate.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: A float-type underwater acoustic recovery device includes an acoustic release unit remotely controlled by a surface deck unit. The release unit contains a transducer and a circuit board, and its bottom has a threaded rotating shaft. The rope hopper is a thin-walled cylindrical structure, comprising a bottom disc and a cylindrical section. A limiting groove is located at the upper end of the cylindrical section. A release block is fixedly mounted on the bottom disc, and has threaded holes. Circular holes are located on both sides of the release block's mounting flange. The upper cover is a disc with a central opening at the rope hopper's opening. The upper cover has a lifting nut and a limiting block, and a release unit clamp is also mounted on it via limiting bolts. The cable is located within the rope hopper cavity and wound around the acoustic release unit. Both ends of the cable are attached to the circular holes on both sides of the release block's mounting flange and the lifting nut on the upper cover. The top of the acoustic release device is equipped with a float by a hanging ring. The cylinder of the acoustic release device passes through the central opening of the upper cover plate. The rotating shaft can be threadedly connected to and separated from the threaded hole of the release block. The limiting groove provided at the upper end of the rope chamber cylinder and the limiting block installed on the upper cover plate cooperate with each other to achieve mutual limiting between the rope chamber and the upper cover plate.

[0007] Furthermore, the release clamp includes two halves of the clamp that are divided into two along the axis of the central hole. The opening size of the release clamp is equal to the cylinder size of the acoustic release device. The two halves of the release clamp can move towards each other to clamp together with the acoustic release device, and the two halves of the release clamp can move in opposite directions to separate from the acoustic release device.

[0008] Furthermore, there are several buoys, and the net buoyancy provided by the several buoys is greater than the underwater weight of the equipment body.

[0009] Furthermore, the bottom disc and cylinder of the rope compartment are respectively provided with several through holes for reducing water flow impact and drainage.

[0010] Furthermore, the upper cover plate is provided with a handle.

[0011] The beneficial effects achieved by this utility model are as follows: This acoustic release device features underwater standby release, positioning, ranging, attitude feedback, underwater levitation, and automatic surfacing upon release. It is remotely controlled from the surface deck unit and can be configured with various underwater equipment, devices, and systems, solving the challenges of underwater release and accurate positioning for retrieval. Furthermore, this device remains suspended underwater, without contact with the seabed, making it suitable for various seabed environments and compatible with a wide range of underwater equipment, devices, and systems, demonstrating broad versatility. The entire device floats in the water, eliminating the need for a surface buoy, increasing its safety and concealment, and effectively preventing damage from human intervention or ship damage.

[0018] The following is in conjunction with the appendix Figure 1-2 This application provides a detailed description of a float-and-rope underwater acoustic recovery device, comprising an acoustic release unit 1, an internal expeller and a circuit board. It features underwater standby release, positioning, ranging, attitude feedback, underwater levitation, and automatic resurfacing upon release. The acoustic release unit 1 is remotely controlled by a surface deck unit. A float 7 is attached to a top ring of the acoustic release unit 1. The bottom rotating shaft 12 of the acoustic release unit 1 has an external thread, allowing it to be threadedly connected and disconnected from the threaded hole of the release block 3. Upon receiving a release command from the surface deck unit, the bottom rotating shaft 12 of the acoustic release unit 1 rotates and separates from the release block 3 at the bottom of the rope cascade 2, thus achieving the release action.

[0019] The rope chamber 2 is a thin-walled cylindrical structure, comprising a bottom disc and a cylindrical body. It can be machined as a single unit or assembled separately. The bottom disc is fitted with a release block 3 as an integral unit. The open end of the cylindrical body has a machined limiting groove that engages with the limiting block 8 mounted on the upper cover plate 5 for positioning. Both the bottom disc and the cylindrical body have openings to reduce water flow impact and facilitate drainage. The rope 4 is coiled inside the rope chamber 2.

[0020] The release block 3 is designed with a mounting flange, which is used to install and fix it to the rope chamber 2 as an integral structure. Each side of the mounting flange of the release block 3 has a round hole machined into it, used to connect the cable 4 inside the rope chamber 2 and various underwater instruments, equipment, devices, and systems. The release block 3 is also designed with a threaded hole, which is used for threaded rotational connection and separation with the external thread of the rotating shaft 12 of the acoustic release device 1.

[0021] The two ends of the cable 4 are respectively attached to the release block 3 and the upper cover plate 5. The main body of the cable 4 is coiled around the acoustic release device 1 in the cavity formed by the cable chamber 2 and the upper cover plate 5. After the acoustic release device 1 completes the release action, the float 7 drives the upper cover plate 5 to float to the surface of the water and is then retrieved. The cable chamber 2, the release block 3, underwater equipment, devices and systems can then be retrieved and brought back onto the ship via the cable 4 attached to the upper cover plate 5.

[0022] The upper cover plate 5 has a disc structure with a central opening that allows the acoustic release device 1 to pass through. Multiple limiting blocks 8 are mounted and fixed on the upper cover plate 5. The upper cover plate 5 can sit at the opening end of the rope compartment 2, and the limiting blocks 8 mounted on the upper cover plate 5 are embedded in the limiting grooves at the opening end of the rope compartment 2. A lifting eye nut 9 is mounted and fixed on the upper cover plate 5, which is used to connect with the cable 4 inside the rope compartment 2. The upper cover plate 5 is fixed and limited by several limiting bolts 10, allowing the two halves of the release device clamp 6 to move only towards or away from each other on the upper cover plate 5. A handle 11 is mounted and fixed on the upper cover plate 5 for easy transport.

[0023] The release clamp 6 is a symmetrical structure with a central opening, divided into two halves along the axis of the central opening. The opening size is the same as the outer cylinder size of the acoustic release device 1. The release clamp 6 is integrated with the upper cover plate 5, and the two halves can only move towards or away from each other on the upper cover plate 5. When the two halves move towards each other, they can clamp tightly with the acoustic release device 1; when the two halves move in opposite directions, they can separate from the acoustic release device 1.

[0024] The buoy 7 serves as the power source for the recovery device's ascent. It remains suspended underwater and is connected to the top ring of the acoustic release device 1. After the acoustic release device completes its release action, the acoustic release device 1 separates from the release block 3, and the buoy 7 drives the acoustic release device 1, the release clamp 6, and the upper cover plate 5 to the surface. In use, several buoys 7 are deployed. The net buoyancy provided by these multiple buoys 7 exceeds the underwater weight of the device itself, thus keeping the device suspended underwater.

[0025] The limiting block 8 is installed and fixed on the upper cover plate 5 as an integral structure. The upper cover plate 5 is located at the opening end of the rope compartment 2, and the limiting block 8 is embedded in the limiting groove at the opening end of the rope compartment 2, restricting the relative movement between the upper cover plate 5 and the rope compartment 2. Furthermore, since the rope compartment 2 and the release block 3 are fixed as one unit, the release clamp 6 holds the acoustic release device 1 tightly, and the clamp is limited by the upper cover plate 5. The center hole of the upper cover plate 5 limits the radial movement of the acoustic release device 1. Therefore, the acoustic release device 1, the upper cover plate 5, the rope compartment 2, and the release block 3 are fixedly connected and have no relative displacement.

[0026] In practical use of this utility model The release mechanism of this invention is connected to the underwater equipment using cables, anchor chains, etc., and the recovery device and the underwater equipment are then lowered into the water together. The acoustic release unit contains a phasor and circuit board, providing functions such as underwater standby release, positioning, ranging, attitude feedback, underwater levitation, and automatic surfacing after release. The surface deck unit is used to send commands from the ship's deck to remotely control the underwater acoustic release unit to perform the release action, provide feedback on ranging, positioning, and attitude information. The surface deck unit can also operate and display the distance to the underwater acoustic release unit, as well as the release unit's positioning and attitude.

[0027] After receiving the release command from the surface deck unit, the acoustic release device performs the release action (the rotating shaft of the acoustic release device rotates). Since the acoustic release device, the top cover plate, the rope compartment, and the release block are fixedly connected and have no relative displacement, the rotating shaft of the acoustic release device rotates and separates from the release block. The float drives the acoustic release device, the release device clamp, and the top cover plate to float to the surface. The float, acoustic release device, release device clamp, and top cover plate can then be manually retrieved onto the ship. The rope compartment, release block, underwater equipment, devices, and systems can then be recovered onto the ship via the cable attached to the top cover plate.

[0028] The above description is only an optional embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
