Description

Technical Field

[0001] The invention relates to the field of deep-sea acoustic detection, and in particular to a deep-sea bottom-seated self-deployable vertical array acoustic buoy. Background Art

[0002] With the research and testing of deep-sea reliable acoustic path detection technology by the hydroacoustic industry, it has been verified that deep-sea sonar nodes can be placed at extremely deep depths in the high seas to achieve the feasibility of upward detection of submarines in a large range of sea areas in the vertical direction. In order to address the problem of weak long-range detection capabilities of enemy quiet submarines in deep-sea environments, it is necessary to conduct research on deep-sea reliable acoustic path detection technology and build deep-sea reliable acoustic path and environment detection nodes. By developing a deep-sea reliable acoustic path detection buoy based on the fusion of deep-sea large-aperture vertical arrays and stereo arrays, the complementary advantages of acoustic information of heterogeneous arrays of large-aperture vertical arrays and stereo arrays can be deeply explored to achieve joint detection of weak targets in the deep sea.

[0003] In order to achieve the above goals, the detection buoy must integrate large-scale acoustic vertical linear arrays and three-dimensional arrays of acoustic sensors, power supply cabins, signal processing electronic cabins for data storage and processing, underwater acoustic communication modules, etc. These modules are integrated through mooring structures and deployed by the mother ship in specific sea areas. They require rapid deployment and expansion of the detection array. After the detection mission is completed, the buoy floats to the sea surface and is salvaged and recovered by the mother ship.

[0004] Traditional acoustic buoys equipped with large-scale vertical arrays are affected by the length of the linear array on the one hand, and the length of the anchor structure below on the other hand. The vertical array on the deck, the buoy body and the anchor system below are deployed in sections into the sea, and cannot be deployed quickly. The vertical array buoy anchored on the seabed has a certain distance from the seabed, and the buoy body, vertical array and three-dimensional array are affected by the ocean current at the depth, and there is a certain degree of rotation, heave and tilt, and the posture cannot maintain vertical stability.

[0005] The deeper the acoustic buoy is deployed for detection using reliable deep-sea sound paths, the lower the ocean environment noise will be, and the larger the "bell"-shaped detection area facing the sea surface will be. This requires that the detection buoy be deployed as close to the bottom layer of the deep sea or even to the seabed as possible. At the same time, the closer to the seabed, the slower the ocean current speed, which helps the buoy to maintain a vertical and stable posture.

[0006] The present invention realizes the integrated integration and rapid deployment of the vertical array, the three-dimensional array, the buoy body and its anchoring structure. The three-dimensional array body is carried on the top of the buoy body. After the detection buoy is buffered and sits on the bottom, the vertical array is autonomously deployed to a vertical posture through the corresponding first-level release mechanism. The advantages of the deep-sea reliable acoustic path and the low noise of the near-seabed environment are utilized to realize active high-gain and no-blind-spot autonomous detection of deep-sea near-surface targets. After the detection mission is completed, the anchoring base is abandoned and the buoy floats to the sea surface, and the mother ship recovers it in sections. Summary of the invention

[0007] The purpose of the present invention is to overcome the shortcomings of the prior art and to provide a deep-sea bottom-seated self-deployed vertical array acoustic buoy, which solves the problems of integrated integration of acoustic buoys based on vertical linear arrays and stereo arrays of hydrophones, autonomous bottom deployment, convenient deployment and recovery, and high-reliability mooring.

[0008] The object of the present invention is achieved through the following technical solution: This deep-sea bottom-seated self-deployable vertical array acoustic buoy comprises:

[0009] An array storage platform is arranged on the top of the acoustic buoy, and the array storage platform includes a vertical array and a vertical array winch for winding the vertical array. One end of the vertical array is connected and fixed to the array storage platform, and the other end of the vertical array is connected to a hanging platform arranged below the array storage platform. Both sides of the vertical array winch are equipped with a first-level parallel releaser for autonomously deploying the vertical array to a vertical posture.

[0010] The equipment platform is fixed below the hanging platform, used to provide buoyancy for the acoustic buoy and carry detection equipment. Secondary parallel releasers are arranged on both sides of the equipment platform, and release chains are suspended below the secondary parallel releasers.

[0011] The three-dimensional array is installed between the equipment platform and the hanging platform;

[0012] A power platform, disposed below the equipment platform, for carrying the battery of the acoustic buoy to realize power supply; and

[0013] A landing anchor is arranged below the power platform. The landing anchor is provided with a distance adjustment mechanism for being sleeved on a release chain. The release chain is tightened by shortening the distance of the distance adjustment mechanism so that the landing anchor is pressed against the equipment platform.

[0014] The first-level parallel releaser is connected to the hanging platform by means of a release rope suspended below. When the release rope is tightened, the equipment platform and the storage array platform are connected in one piece, and the acoustic buoy is in a deployed state. When the first-level parallel releaser is released, the release rope is disengaged from the hanging platform, so that the storage array platform and the hanging platform are connected only through the vertical array, and the acoustic buoy is in a working state. When the second-level parallel releaser is released, the release chain is disengaged from the landing anchor, so that the power platform is separated from the landing anchor, and the abandonment is achieved, and the acoustic buoy is in a recovery state.

[0015] As a further technical solution, the power platform is provided with a rectangular power platform frame, the four corners of the frame of the power platform frame are four vertical pipes, a battery compartment base is arranged inside the power platform frame for supporting the battery compartment clamp, the battery compartment is clamped by the battery compartment clamp, and the battery of the acoustic buoy is carried in the battery compartment.

[0016] As a further technical solution, a release baffle is provided in the middle of the power platform frame to separate the release chain from the battery compartment, and the release baffle is made of a thin plate with multiple holes.

[0017] As a further technical solution, the landing anchor also includes an anchor base, a base locating pin and a shock-absorbing spring. The anchor base is used to act as a landing base and a counterweight for the submersible buoy, and also serves as a ballast. The base locating pins are arranged on the anchor bases at the four corners of the landing anchor to cooperate with the four vertical pipes of the power platform to achieve installation positioning. A shock-absorbing spring is arranged around the outer periphery of the base locating pins.

[0018] As a further technical solution, the pitch adjustment mechanism includes a pitch adjustment screw and a pitch adjustment release ring whose distance relative to the pitch adjustment screw is adjustable. The pitch adjustment release ring is sleeved on the release chain, and the pitch adjustment screw and the pitch adjustment release ring are threadedly connected to achieve pitch adjustment.

[0019] As a further technical solution, the equipment platform includes an equipment platform frame, and four vertical pipes are correspondingly arranged at the four corners of the equipment platform frame. An equipment float is arranged inside the equipment platform frame, and a cavity is provided inside the equipment float for installing or carrying an underwater acoustic communication device, a beacon device, a three-dimensional array electronic cabin, a signal processing cabin, a formation monitoring electronic cabin, a formation monitoring transducer and a secondary parallel releaser, etc.

[0020] As a further technical solution, an equipment float pressure plate is installed on the top of the equipment platform frame to press the equipment float. A storage array platform limit pin is provided on the equipment float pressure plate. A storage array platform limit tube is provided on the support leg of the vertical array winch to be vertically fitted on the storage array platform limit pin. The roller of the vertical array winch is filled with a storage array float, an acoustic sensor is provided in the vertical array, and an attitude sensor and a depth sensor are provided at the head and tail of the vertical array respectively.

[0021] As a further technical solution, a release hook and a release chain are connected in sequence below the secondary parallel releaser, and the release chain passes through the adjustable release ring in sequence and is connected to the release hook under the releaser on the other side.

[0022] As a further technical solution, two guide rings are provided on the lifting platform, and a release hook and a release rope are connected in sequence below the first-level parallel releaser. The release rope passes through the two guide rings in sequence and is connected to the release hook on the other side.

[0023] As a further technical solution, support rods are provided on the four corners of the hoisting platform. The support rods pass through the four vertical pipes on the equipment platform and the power platform. A hoisting block is installed on the upper end of each support rod and an anchor limit pipe is installed on the lower end, so that the power platform, equipment platform and hoisting platform are connected in series to form the main body of the submerged buoy. Elastic gaskets are installed between the power platform and the equipment platform, between the power platform and the landing anchor, and between the equipment platform and the hoisting platform.

[0024] The beneficial effects of the present invention are:

[0025] 1. The submerged buoy system has three forms: in the deployment state, it is an integrated structure, which realizes rapid deployment on the deck and cushioned landing by the landing anchor; after landing on the bottom, the first-level parallel releaser is released, the storage array platform floats up, the vertical array is deployed to a vertical posture, and converted to a working state, which is fast and efficient; in the recovery state, the second-level parallel releaser releases and abandons the landing anchor, and the submerged buoy floats to the sea surface in sections and is recovered in sections by the mother ship, which has the characteristics of safe cushioned deployment on the bottom and high reliability recovery;

[0026] 2. The power platform is equipped with the battery of the acoustic buoy as a power supply. At the same time, it can lower the center of gravity of the buoy as much as possible, which helps the buoy to maintain a vertical posture;

[0028] 4. A damping spring is sleeved around the base positioning pin, which can reduce vibration when the buoy lands, and can also play a thrust role when the secondary parallel releaser releases the landing anchor during recovery, so as to prevent the buoy from sinking into the seabed mud and being unable to float up for recovery;

[0029] 5. The cavity formed inside the equipment float is convenient for the installation and storage of various equipment. At the same time, metal threaded holes are embedded in the float to facilitate the installation and disassembly of various equipment;

[0030] 6. Both the first and second stage releasers adopt a symmetrical parallel design. As long as one releaser of any release mechanism is released, the release can be guaranteed to be successful, thus improving reliability. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0041] The present invention will be described in detail below with reference to the accompanying drawings:

[0042] Example: As shown in the attached Figures 1 to 9 As shown, this deep-sea bottom-seated self-deployed vertical array acoustic buoy includes a landing anchor 1, a power platform 2, an equipment platform 3, an array storage platform 4, a hoisting platform 5, a three-dimensional array 6, an anchor base 1-1, a limit pin 1-2, a buffer spring 1-3, a pitch adjustment screw 1-4, a pitch adjustment release ring 1-5, a power platform frame 2-1, a battery compartment base 2-2, a battery compartment clamp 2-3, a battery compartment 2-4, a release baffle 2-5, an equipment platform frame 3-1, an equipment float 3-2, an underwater acoustic communication device 3-3, a beacon 3-4, a three-dimensional array electronic Cabin 3-5, signal processing cabin 3-6, formation monitoring electronic cabin 3-7, formation monitoring transducer 3-8, secondary parallel releaser 3-9, equipment float pressure plate 3-10, storage array platform limit pin 3-11, vertical array 4-1, vertical array winch 4-2, storage array float 4-3, primary parallel releaser 4-4, storage array platform limit tube 4-5, release chain 5-1, release hook 5-2, release rope 5-3, release rope guide ring 5-4, support rod 5-5, elastic gasket 5-6, lifting block 5-7 and anchor limit tube 5-8.

[0043] Reference Figure 1, 2 , the storage array platform 4 is set on the top of the acoustic buoy, such as Figure 7 As shown, the storage array platform 4 includes a vertical array 4-1 and a vertical array winch 4-2. The vertical array 4-1 is coiled on the vertical array winch 4-2. One end of the vertical array 4-1 is connected and fixed to the storage array platform 4, and the other end of the vertical array 4-1 is connected to the hoisting platform 5 set below the storage array platform 4. Both sides of the vertical array winch 4-2 are equipped with a primary parallel releaser 4-4, which can autonomously unfold the vertical array 4-1 to a vertical posture. Figure 8 The first-level parallel releaser 4-4 is connected to the hanging platform 5 by means of the release rope 5-3 suspended below. When the release rope 5-3 is tightened, the equipment platform 3 and the storage array platform 4 are connected as a whole, and the acoustic buoy is in a deployed state; when the first-level parallel releaser 4-4 is released, the release rope 5-3 is disengaged from the hanging platform 5, so that the storage array platform 4 and the hanging platform 5 are connected only through the vertical array 4-1, and the acoustic buoy is in a working state.

[0044] The equipment platform 3 is fixed below the hanging platform 5, and can provide buoyancy for the acoustic buoy and carry detection equipment. Secondary parallel releasers 3-9 are arranged on both sides of the equipment platform 3, and a release chain 5-1 is suspended below the secondary parallel releasers 3-9. Figure 6 As shown, the equipment platform 3 includes an equipment platform frame 3-1, and four vertical pipes are also arranged at the four corners of the equipment platform frame 3-1. An equipment float 3-2 is arranged in the equipment platform frame 3-1. The equipment float 3-2 has a cavity inside, which can be installed or carried with an underwater acoustic communication machine 3-3, a beacon machine 3-4, a three-dimensional array electronic cabin 3-5, a signal processing cabin 3-6, a formation monitoring electronic cabin 3-7, a formation monitoring transducer 3-8 and a secondary parallel releaser 3-9. The metal threaded holes are embedded in the equipment float 3-2 to facilitate the installation and removal of various equipment. In addition, an equipment float pressure plate 3-10 is installed on the top of the equipment platform frame 3-1, which can press the equipment float 3-2. The equipment float pressure plate 3-10 is provided with a storage array platform limit pin 3-11. The storage array platform limit pipe 4-5 is provided on the support leg of the vertical array winch 4-2. The storage array platform limit pipe 4-5 can be vertically fitted on the storage array platform limit pin 3-11. Preferably, the storage array float 4-3 is filled inside the roller of the vertical array winch 4-2, the vertical array 4-1 is equipped with an acoustic sensor, and the head and tail of the vertical array 4-1 are each equipped with a posture sensor and a depth sensor. Fig. 9 As shown, the release hook 5-2 and the release chain 5-1 are connected in sequence below the secondary parallel releaser 3-9, and the release chain 5-1 passes through the adjustable release ring 1-5 in sequence and is connected to the release hook 5-2 under the releaser on the other side. Fig. 9As shown, when the secondary parallel releaser 3-9 is released, the release chain 5-1 is disconnected from the landing anchor 1, so that the power platform 2 is separated from the landing anchor 1, and the acoustic buoy is in a recovery state. A three-dimensional array 6 is also installed between the equipment platform 3 and the suspension platform 5.

[0045] like Figure 5 As shown, the power platform 2 is arranged below the equipment platform 3, and can carry the battery of the acoustic buoy to realize power supply. The power platform 2 is provided with a rectangular power platform frame 2-1, and the four corners of the frame of the power platform frame 2-1 are four vertical pipes. A battery compartment base 2-2 is arranged in the power platform frame 2-1, which can support the battery compartment clamp 2-3. The battery compartment 2-4 is clamped by the battery compartment clamp 2-3. The battery of the acoustic buoy is carried in the battery compartment 2-4 as a power supply. At the same time, the center of gravity of the buoy can be reduced as much as possible, which helps the buoy to maintain a vertical posture. A release baffle 2-5 is provided in the middle of the power platform frame 2-1 to separate the release chain 5-1 from the battery compartment 2-4. The release baffle 2-5 is a thin plate with multiple holes. The main function is to prevent the release chain 5-1 from swinging and damaging the relevant equipment on the battery compartment platform when the secondary parallel releaser 3-9 is unhooked.

[0046] Reference Figure 3 , 4 The landing anchor 1 is arranged below the power platform 2. The landing anchor 1 is provided with a distance adjustment mechanism, which can be put on the release chain 5-1. The release chain 5-1 is tightened by shortening the spacing of the distance adjustment mechanism, so that the landing anchor 1 is pressed relative to the equipment platform 3. Preferably, the distance adjustment mechanism includes a distance adjustment screw 1-4 and a distance adjustment release ring 1-5 with an adjustable distance relative to the distance adjustment screw 1-4. The distance adjustment release ring 1-5 is put on the release chain 5-1. The distance adjustment screw 1-4 and the distance adjustment release ring 1-5 are threadedly connected to achieve distance adjustment. Furthermore, the landing anchor 1 also includes an anchor base 1-1, a base locating pin 1-2 and a shock-absorbing spring 1-3. The anchor base 1-1 can serve as a landing base and a submersible buoy counterweight, and also play a role of ballast. It is made of metal materials such as stainless steel. The base locating pins 1-2 are arranged on the anchor base 1-1 at the four corners of the landing anchor 1, and can cooperate with the four vertical pipes of the power platform 2 to achieve installation and positioning. The outer periphery of the base locating pins 1-2 is sleeved with a shock-absorbing spring 1-3. The shock-absorbing spring 1-3 can reduce vibration when the buoy lands, and on the other hand, it can play a boosting role when the secondary parallel releaser 3-9 releases the landing anchor 1 during the recovery process, so as to prevent the buoy from sinking into the seabed mud and being unable to float for recovery.

[0047] like Figure 1 , 2As shown in Figures 8 and 9, two guide rings 5-4 are provided on the hanging platform 5, and the release hook 5-2 and the release rope 5-3 are connected in sequence below the first-level parallel releaser 4-4. The release rope 5-3 passes through the two guide rings 5-4 in sequence and is connected to the release hook 5-2 on the other side. When the release rope 5-3 is tightened, the equipment platform 3 and the storage array platform 4 are fastened together, realizing the integrated design of each functional platform. Since the releasers are all designed in symmetrical parallel, any first-level release mechanism can ensure the release success as long as one releaser is released, thereby improving the release reliability. Preferably, support rods 5-5 are provided on the four corners of the hanging platform 5, and the support rods 5-5 correspond to the four vertical pipes passing through the equipment platform 3 and the power platform 2. A hanging block 5-7 is installed on the upper end of each support rod 5-5, and an anchor limiting tube 5-8 is installed on the lower end, so that the power platform 2, the equipment platform 3 and the hanging platform 5 are connected in series to form a submerged buoy body, and elastic gaskets 5-6 are installed between the power platform 2 and the equipment platform 3, between the power platform 2 and the landing anchor 1, and between the equipment platform 3 and the hanging platform 5.

[0048] The lifting platform 5, the equipment platform 3 and the power supply platform 2 constitute the main body of the buoy. The main body of the buoy and the storage array platform 4, the main body of the buoy and the landing anchor 1 are first constrained and installed by limit tubes and limit pins, and then the three are tightly formed into a whole by tightening the release rope or release chain.

[0049] Working process of the present invention:

[0050] The deep-sea bottom-seated self-deployable vertical array acoustic buoy of the present invention is directly unhooked and placed into the water through the stern hanger or slide. When the ranging data returned by the acoustic releaser remains basically unchanged, or the depth data of the vertical array lower end depth sensor returned by the hydroacoustic communication device remains basically unchanged and close to the seabed depth in the nautical chart, it indicates that the buoy has landed on the seabed. The releaser deck unit commands the first-level parallel releaser 4-4 on the storage array platform 4 to release, the release rope 5-3 is unhooked, and the storage array platform 4 is separated from the equipment platform 3 under the action of its own buoyancy, such as Figure 2 As shown, the vertical array 4-1 on the vertical array winch 4-2 is pulled out at the same time. When the pitch angle of the vertical array attitude data sent back by the acoustic communication device is nearly 90° or the difference between the two depth sensors at the head and tail of the vertical array is the vertical array length, it indicates that the vertical array 4-1 has been completely released from the storage array platform 4 and deployed to a vertical state. During recovery, the releaser deck unit commands the secondary parallel releaser 3-9 on the equipment platform 3 to unhook, and the buoy immediately abandons the landing anchor 1. At this time, the buoy's buoyancy in the water is greater than its own weight, and the storage array platform 4 and the buoy body (hanging platform 5, equipment platform 3, power platform 2) float to the sea surface and are salvaged and recovered by the mother ship.

[0051] It is understandable that, for those skilled in the art, any equivalent replacement or change to the technical solution and inventive concept of the present invention should fall within the protection scope of the claims attached to the present invention.
