Description

Technical Field

[0001] This invention relates to the field of deep-sea underwater monitoring and communication equipment technology, specifically to a multi-functional communication device that integrates sea and air communication. Background Technology

[0002] The ocean has enormous resources and value waiting to be developed and utilized by people. However, humans have only explored about 5% of the ocean so far. The main reason is that in addition to facing and overcoming many natural problems such as high pressure, unstable water temperature, darkness, lack of oxygen and highly corrosive seawater, we also face difficulties such as not being able to see or hear clearly or far in the deep sea using man-made equipment, as well as the difficulty in achieving communication and interconnection.

[0003] To create a transparent ocean and provide technical support for the development and utilization of marine resources, existing technologies use communication relay methods such as fixed buoys or temporarily deployed buoys to solve communication between underwater and surface users (including surface users (e.g., ships, unmanned surface vessels, buoys, etc.), aerial platforms (e.g., flying platforms (e.g., airplanes, drones, balloons, airships, etc.), sky platforms (e.g., platforms using satellite nodes), or land platforms (e.g., land-based base stations, shore control rooms, radio transceivers, etc.)). However, most underwater acoustic devices currently only support a single mode of communication, which is limited and cannot meet the diverse needs of users. Summary of the Invention

[0004] This invention addresses the aforementioned technical problems of existing underwater communication equipment by proposing a multi-functional communication device that integrates sea and air communication. It supports both underwater acoustic and BeiDou communication methods and can independently employ either BeiDou buoys or acoustic beacons depending on the application scenario.

[0005] To achieve the above-mentioned objectives, the present invention employs the following technical solution: This invention provides a multi-functional communication device that integrates sea and air communication, comprising: Beidou communication module; The underwater acoustic communication module includes: A transducer is used to transmit and receive underwater acoustic signals and to convert between acoustic and electrical signals. The control module includes: The signal input processing module communicates with the transducer to convert and process the input signal to the transducer. The signal output processing module communicates with the transducer to convert and process the output signal of the transducer. The acoustic control unit communicates with the signal input processing module and the signal output processing module, and communicates bidirectionally with the Beidou communication module; The integrated control and processing unit can be used to encode, modulate, decode, and store data, and communicates bidirectionally with the acoustic control unit; The host computer communicates with the integrated control and processing unit and with the acoustic control unit bidirectionally. A cable release device is located below the underwater acoustic communication module and communicates with the acoustic control unit. An anchor device, connected to the cable release device; When the transducer receives the first underwater acoustic trigger signal, the acoustic control unit can transmit the original signal processed by the transducer through the signal input processing module to the host computer or to the integrated control processing unit for processing and storage, or process and transmit it to the host computer. Upon receiving a communication command from a host computer or integrated control processing unit, the acoustic control unit can transmit the signal to the signal output processing module and output the processed signal through the transducer. When the BeiDou communication module receives a BeiDou signal, the acoustic control unit can transmit the received BeiDou signal to the integrated control processing unit and the host computer. The integrated control processing unit processes the signal and sends a communication command to the acoustic control unit through the integrated control processing unit or the host computer. The acoustic control unit then transmits the signal to the signal output processing module, which processes the signal and transmits it through a transducer to emit an underwater acoustic signal or transmits the signal to the BeiDou communication module. The BeiDou communication module then calculates the signal and emits the BeiDou signal. When the transducer receives the second acoustic signal, the acoustic control unit can transmit the signal from the signal input processing module to the integrated control processing unit and the host computer. The integrated control processing unit processes the signal and sends communication commands to the acoustic control unit through the integrated control processing unit or the host computer. The acoustic control unit then transmits the signal to the Beidou communication module to transmit the Beidou signal, or the acoustic control unit transmits the signal to the signal output processing module. After processing, the signal is transmitted as an underwater acoustic signal through the transducer. When the transducer receives the release cable signal, it transmits the signal to the signal input processing module. The acoustic control unit can then transmit the signal from the signal input processing unit to the integrated control processing unit and the host computer. The integrated control processing unit processes the signal and sends instructions to the acoustic control unit, which in turn sends instructions to control the cable release device.

[0006] A method for deploying a multi-functional cross-sea and air communication device based on the above technical solution includes the following steps: Deploy the required multi-functional communication equipment that spans sea and air; The anchoring device is placed at the stern of the vessel being deployed, and the vessel is kept traveling in a straight line at a low speed. Wind a rope to the required depth on the cable release device; The Beidou communication module is used to deploy the recovery ring, which is then placed in the sea. The connecting cable between the Beidou communication module and the underwater acoustic communication module is lowered, and a first buoyancy material module is installed on the cable before deploying the underwater acoustic communication module. Connect the cable and anchor device at the end of the cable release device; When the deployed vessel is controlled to sail at a low speed to the preset station, the anchor device is thrown into the sea; As the anchor device descends, it pulls the Beidou communication module and the underwater acoustic communication module, which are floating on the sea surface, underwater in sequence. After the first phase, the anchor device was deployed and landed, and the Beidou communication module floated to the surface of the sea, completing the deployment.

When in use, Beidou buoys or acoustic beacons can be used separately depending on the application scenario. The beacon as a whole can be used as a buoy, or the Beidou communication unit can be removed and used as a submersible. When used alone as a submersible, it can only be used for underwater acoustic communication. The application scenarios are flexible and can be determined according to user needs.

[0013] This invention proposes an embodiment of a multi-functional communication device that integrates sea and air communication, which mainly includes: The system consists of three main parts: the Beidou communication module, the underwater acoustic communication module, and the anchor device. It also includes auxiliary modules, which mainly include auxiliary buoyancy material modules, cables, etc.

[0014] The underwater acoustic communication module is mainly used for the data acquisition, recording, and data analysis and calculation software and hardware of the underwater acoustic communication unit. It is a key component of the device and needs to be programmed to implement the various functions required by the device.

[0015] The underwater acoustic communication module includes: A transducer is used to transmit and receive underwater acoustic signals and to convert between acoustic and electrical signals. The underwater acoustic communication module also includes an equipment compartment, which houses the battery module, as well as a charging / discharging module and a control module for managing and controlling the charging and discharging of the battery module.

[0016] The transducer device is located on the top of the equipment compartment.

[0017] The equipment compartment is a stainless steel cylinder with a working depth of 150 meters and an operational depth of 60 meters. It has openings at both ends and is sealed with O-rings.

[0018] The transducer unit is located at the top of the equipment compartment, and a protective cover surrounds the transducer unit and is connected to the upper end cover.

[0019] Inside the equipment compartment are the control modules, and the lower end cover is a watertight connector.

[0020] The control module, located inside the equipment compartment, includes: The signal input processing module communicates with the transducer to convert and process the input signal to the transducer. The signal output processing module communicates with the transducer to convert and process the signals output to the transducer. In some embodiments of this application, the signal input processing module includes: Amplifiers, analog filters, A / D converter modules, and digital filters; the A / D converter module is integrated on the A / D converter chip. The signal output processing module includes a D / A digital-to-analog converter module and a transducer drive circuit module. The transducer drive circuit module is a drive circuit with amplification function and can directly adopt existing circuit structures.

[0021] The D / A digital-to-analog converter module is integrated on the D / A digital-to-analog converter chip.

[0022] The acoustic control unit communicates with the signal input processing module and the signal output processing module. It communicates bidirectionally with the Beidou communication module. The acoustic control unit can transmit signals to the signal output processing module, receive signals from the signal input processing module, and receive or transmit signals to the Beidou communication module.

[0023] The acoustic control unit is a programmable logic array, that is, integrated on an FPGA chip.

[0024] The integrated control and processing unit can be used to encode, modulate, and decode data, as well as store data in file form, and communicate bidirectionally with the acoustic control unit; the integrated control and processing unit is integrated on a digital signal processing chip (DSP).

[0025] The host computer communicates with the integrated control and processing unit and with the acoustic control unit bidirectionally. A cable release device is located below the underwater acoustic communication module and communicates with the acoustic control unit. An anchor device, connected to the cable release device; Single underwater acoustic signal reception: When the transducer receives the first underwater acoustic trigger signal, the acoustic control unit can transmit the original signal processed by the transducer through the signal input processing module to the host computer or to the integrated control processing unit for processing and storage, or process and transmit it to the host computer. The first underwater acoustic signal is a single underwater acoustic signal. After the transducer receives the first underwater acoustic signal, it converts the acoustic signal into an electrical signal for acquisition and transmission to the signal amplifier for amplification. Then, it passes through the signal filter for the first filtering and is transmitted to the A / D analog-to-digital converter chip to convert the analog signal into a digital signal. After conversion, it enters the digital signal filter for the second filtering and enters the programmable logic array (FPGA) for aggregation.

[0026] The FPGA can transmit the raw, unprocessed signal directly to the host computer via a 422 cable or network interface, or it can transmit the signal to a digital signal processing chip (DSP) for encoding, modulation, and decoding via a parallel serial port. The processed signal can be stored in the DSP in MATLAB format or uploaded to the host computer via a 422 cable or network interface to complete the signal reception.

[0027] Single underwater acoustic signal transmission: Upon receiving a communication command from a host computer or integrated control processing unit, the acoustic control unit can transmit the signal to the signal output processing module and output the processed signal through the transducer. The host computer or a control program pre-written on the digital signal processing chip (DSP) sends communication commands to the programmable logic array (FPGA). The FPGA transmits the signal to the D / A digital-to-analog converter chip, and after passing through the transducer drive circuit, the converted analog signal is amplified and transmitted to the transducer to emit underwater acoustic signals.

[0028] Transceiver combination of BeiDou communication and underwater acoustic communication: 1. Receive BeiDou signals and transmit underwater acoustic signals. When the BeiDou communication module receives a BeiDou signal, the acoustic control unit can transmit the received BeiDou signal to the integrated control processing unit and the host computer. The integrated control processing unit processes the signal and sends communication commands to the acoustic control unit through the integrated control processing unit or the host computer. The acoustic control unit then transmits the signal to the signal output processing module, which processes the signal and transmits the underwater acoustic signal through the transducer. After receiving the BeiDou wireless signal, the BeiDou communication antenna transmits it to the BeiDou communication module via a 422 cable and then to the programmable logic array (FPGA) for aggregation. The FPGA then transmits the signal to the DSP and the host computer. The DSP encodes, modulates, decodes, and stores the signal. Afterward, the DSP or the host computer sends a communication command to the FPGA. The FPGA then transmits the signal to the D / A digital-to-analog converter chip, and after passing through the transducer drive circuit, the converted analog signal is amplified and transmitted to the transducer to emit underwater acoustic signals.

[0029] 2. Receive BeiDou signals and transmit BeiDou signals. When the BeiDou communication module receives a BeiDou signal, the acoustic control unit can transmit the received BeiDou signal to the integrated control processing unit and the host computer. The integrated control processing unit processes the signal and sends a communication command to the acoustic control unit through the integrated control processing unit or the host computer. The acoustic control unit then transmits the signal to the BeiDou communication module, which calculates the signal and then transmits the BeiDou signal. After receiving the BeiDou wireless signal, the BeiDou communication antenna transmits it to the BeiDou communication module via a 422 cable and then to the programmable logic array (FPGA) for aggregation. The FPGA then transmits the signal to the DSP and the host computer. The DSP encodes, modulates, decodes, and stores the signal. Afterward, the DSP or the host computer sends a communication command to the FPGA, which then transmits the signal to the BeiDou communication module. The BeiDou communication module decodes the signal and then transmits the BeiDou signal.

[0030] 3. Receive underwater acoustic signals and transmit BeiDou signals. When the transducer receives the second acoustic signal, the acoustic control unit can transmit the signal from the signal input processing module to the integrated control processing unit and the host computer. The integrated control processing unit processes the signal and sends communication commands to the acoustic control unit through the integrated control processing unit or the host computer. The acoustic control unit then transmits the signal to the BeiDou communication module to transmit the BeiDou signal. After receiving the acoustic signal, the transducer converts it into an electrical signal for acquisition and transmission to a signal amplifier for amplification. The signal then undergoes its first filtering step via a signal filter, followed by transmission to an A / D (analog-to-digital) converter chip to convert the analog signal into a digital signal. This digital signal then undergoes a second filtering step via a digital signal filter before being processed by a programmable logic array (FPGA). The FPGA then transmits the signal to a DSP (Digital Signal Processor) and a host computer. The DSP encodes, modulates, decodes, and stores the signal. Finally, the DSP or host computer sends communication commands to the FPGA, which then transmits the signal to the BeiDou communication module. The BeiDou communication module decodes the signal and transmits it as a BeiDou signal.

[0031] 4. Receive underwater acoustic signals and transmit underwater acoustic signals. When the transducer receives the second acoustic signal, the acoustic control unit can transmit the signal transmitted from the signal input processing module to the integrated control processing unit and the host computer. The integrated control processing unit processes the signal and sends communication commands to the acoustic control unit through the integrated control processing unit or the host computer. The acoustic control unit transmits the signal to the signal output processing module, and the processed signal is emitted as an underwater acoustic signal through the transducer. After receiving the acoustic signal, the transducer converts it into an electrical signal for acquisition and transmission to a signal amplifier for amplification. The signal then undergoes a first filtering step via a signal filter, followed by transmission to an A / D converter chip to convert the analog signal into a digital signal. This digital signal then undergoes a second filtering step via a digital signal filter before being processed by a programmable logic array (FPGA). The FPGA then transmits the signal to a DSP and a host computer. The DSP encodes, modulates, decodes, and stores the signal. Subsequently, the DSP or host computer sends communication commands to the FPGA, which transmits the signal to a D / A converter chip. The transducer driver circuit amplifies the converted analog signal and transmits it to the transducer for underwater acoustic signal transmission.

[0032] When the transducer receives the release cable signal, it transmits the signal to the signal input processing module. The acoustic control unit can transmit the signal from the signal input processing unit to the integrated control processing unit and the host computer. The integrated control processing unit processes the signal and sends instructions to the acoustic control unit. The acoustic control unit then sends instructions to control the operation of the cable release device.

[0033] After receiving the release command acoustic signal from the survey vessel, the transducer converts the acoustic signal into an electrical signal, which is then amplified by a signal amplifier. The signal is then filtered for the first time by a signal filter, and subsequently transmitted to an A / D converter chip to convert the analog signal into a digital signal. After conversion, the signal undergoes a second filtering by a digital signal filter before being processed by a programmable logic array (FPGA). The FPGA then transmits the signal to a DSP and a host computer. The DSP encodes, modulates, and decodes the signal. Finally, the DSP sends a release command to the FPGA, which drives the electromagnet control module to release the cable, allowing the equipment to be retrieved. After signal transmission is complete, the cable release device can also send a confirmation signal back to the FPGA so that the host computer can confirm that the cable has been released.

[0034] In this embodiment, the multi-functional communication device that integrates sea and air communication can realize the mutual conversion and transmission of underwater acoustic signals and Beidou communication signals. It supports both underwater acoustic and Beidou communication methods, and can perform Beidou (high-speed data transmission) and underwater acoustic communication (low speed). It also has the ability to generate underwater acoustic codes based on Beidou short message information modulation. When in use, Beidou buoys or acoustic beacons can be used separately depending on the application scenario. The beacon as a whole can be used as a buoy, or the Beidou communication module can be removed and used as a submersible beacon. When used alone as a submersible beacon, only underwater acoustic communication can be carried out. The application scenarios are flexible and can be determined according to user needs.

[0035] The equipment compartment also houses a battery module, which uses 18650 rechargeable lithium batteries with a single-cell voltage of 3.2 ~ 3.7 V and a single-cell capacity of 2.2 ~ 2.6 AH. A charge / discharge management module is also located inside the equipment compartment to provide a stable power output for the entire device.

The connecting seat 150 is arranged in the wrapping space, and the shape of the wrapping space and the connecting seat 150 are adapted.

[0058] The annular wrapping part 112 is an annular wrapping tube, and the connecting seat 150 is cylindrical and arranged inside the annular wrapping tube.

[0059] To reduce the weight of the entire Beidou communication device and ensure that it can float on the sea surface, the outer shell 110 is made of plastic, and the connector 150 and antenna support 160 are both made of carbon fiber.

[0063] The limit guide ribs can also enhance the strength of the entire connector 150.

[0064] In some embodiments of this application, a first locking assembly is further included, comprising a plurality of first locking components arranged circumferentially along the connecting seat 150. The first locking components include: The first locking bolt, the first locking member passes through the annular wrapping part 112 and the connecting seat 150 from top to bottom; The first locking nut is locked and fixed at the end of the first locking bolt that extends from the connecting seat 150.

[0068] In some embodiments of this application, the annular frame 170 includes: a first annular portion 171, which is sleeved on the outside of the annular wrapping portion 112; The second annular portion 172 is arranged around the outside of the first annular portion 171, and its inner diameter is larger than the inner diameter of the first annular portion 171. And a connecting reinforcement 173 connecting the first annular portion 171 and the second annular portion 172, wherein a hollow hook portion 174 is formed between the annular reinforcement, the first annular portion 171 and the second annular portion 172.

[0069] The first annular portion 171 is a first annular ring, the interior of which is hollow; The second annular part 172 is a second annular ring, and its interior is also hollow to reduce the weight of the entire Beidou communication device.

[0070] The connecting reinforcement 173 is a connecting reinforcement rod used to connect the first annular ring and the second annular ring.

[0071] By connecting the ring frame 170 to the outside of the outer shell 110 and the connecting seat 150, the entire Beidou communication device can be subjected to relatively uniform force when it is hit by waves, because it is ring-shaped, thus ensuring that the entire Beidou communication device is in a relatively stable state. Furthermore, the hollow hook 174 formed above it facilitates the salvage or recovery of the entire Beidou communication device.

[0072] In some embodiments of this application, the antenna support 160 is an antenna support rod with a receiving cavity formed inside it, arranged along its height. The BeiDou communication component is inserted into the top of the receiving cavity, with its head protruding from the receiving cavity. To reduce the weight of the entire BeiDou communication device, the antenna support rod is also made of carbon fiber, making it lightweight.

[0073] In some embodiments of this application, the glass float 120 includes an upper glass float 120 and a lower glass float 120. The upper glass float 120 and the lower glass float 120 are joined together and sealed by a sealing ring to ensure the airtightness of the entire spherical space formed therein, and to prevent water from entering the internal electronic control component 141.

[0074] In some embodiments of this application, the heat dissipation component 140 includes a heat dissipation aluminum plate shell 142 adapted to the shape of the lower glass float 120, a filling cavity is formed in the heat dissipation aluminum plate shell 142, and the fluid foam copper 143 is filled in the filling cavity.

[0075] In this embodiment, the underwater deployment system, through the Beidou communication module floating on the sea surface, can realize two different operating conditions: buoy and submersible.

[0076] In use, the Beidou communication unit and the underwater acoustic communication module can be connected via a cable. Specifically, the cable is connected to the watertight connector at the bottom of the Beidou communication module's casing, and then connected to the equipment compartment via an 80-100 meter anti-twist cable, enabling signal and data transmission between the Beidou communication module and the equipment compartment's control module. The cable end uses a high-strength braided mesh to connect to the unit, minimizing bending and stress at the cable end. When a buoy is needed, the Beidou communication module in the underwater deployment system can be removed, which can meet the deployment needs of the entire deployment system hidden on the seabed. When a buoy is needed, the entire buoy can be made to float on the sea by using the Beidou communication module that floats on the sea surface.

[0077] Because the underwater deployment system in this embodiment can achieve different methods of buoy and submersible deployment, the equipment can form a variety of different networking forms.

[0078] The equipment network can be completed by different combinations of buoys and moorings. Depending on the work requirements, three methods can be adopted: networking multiple buoys, networking multiple moorings, and networking a mixture of multiple buoys and moorings.

[0079] Considering the 10 km underwater communication distance and the transmission distance of the Beidou communication module, the straight-line distance between each node is approximately 10 km.

[0080] Wireless data transmission takes place between the buoy and the survey vessel; therefore, when all underwater buoys are used in a network, wireless data transmission capability is not available.

[0081] After determining the farthest acoustic communication distance using hydrophones and linear motion, the survey vessel completed the deployment of the last target.

[0082] The cable release device is connected below the underwater acoustic communication module and includes: The substrate 310 has a placement space 311 formed inside it; In some embodiments of this application, the substrate includes: A first base plate 314, a second base plate 315, and a connecting plate for connecting the first base plate and the second base plate 315 are interconnected to form a U-shaped base structure.

[0083] The first base plate 314 and the second base plate 315 are arranged opposite to each other, and the placement space 311 is formed between the first base plate 314, the second base plate 315 and the connecting plate.

[0084] The connecting plate is provided with threaded mounting holes, and bolts are installed in the threaded mounting holes to connect and fix the base body and the underwater equipment used for underwater operations together.

[0085] A rolling component 320 is located within the placement space 311 and is rotatably mounted on the base. A cable 700 is wound around the rolling component 320, and the cable 700 has a free end that is connected to the anchor device 600. In some embodiments of this application, the rolling component 320 is a roller. The cable 700 is wound around the surface of the roller, and the end of the cable 700 not wound around the surface of the roller, i.e., its free end, is used to connect the anchor device 600.

[0086] During assembly, the roller is mounted on the base via a mounting shaft. Both ends of the roller are rotatably connected to the mounting shaft via bearings. One end of the mounting shaft has an external thread. The mounting shaft passes through the first base plate 314 and the second base plate 315 in sequence and is then locked and fixed together with the base by tightening a nut.

[0087] An elastic limiting structure is arranged on the base 310 to limit the rotation of the rolling component 320; In some embodiments of this application, the elastic limiting structure 400 includes: A limiting insert 410 is inserted into the rolling member 320 through the base 310, and the limiting insert includes an abutment portion 411 located outside the base. The second elastic element 420 is sleeved on the limiting insert 410, with one end abutting against the abutting part 411 and the other end abutting against the outer wall of the substrate.

[0088] The limiting insert 410 is a limiting insert pin, and the abutting part 411 is an annular abutting protrusion formed at one end of the limiting insert.

[0089] The second elastic element 420 is a second spring, which is sleeved on the limiting insert pin, with one end abutting against the annular abutting protrusion and the other end abutting against the base.

[0090] In some embodiments, a groove is provided on the outer wall of the substrate 310, and a clearance hole is provided at the groove. Specifically, a clearance hole for clearance is provided on the first substrate plate 314, and the second elastic element is located in the groove.

[0091] In some embodiments of this application, a spoke is provided on one side of the roller, and a limit hole is provided on the spoke. The clearance hole and the limit hole are coaxially arranged.

[0092] During assembly, the limiting pin passes through the second elastic element 420 and the clearance hole in sequence and is then inserted into the limiting hole to lock the roller and prevent it from rotating.

[0093] When the restriction on the elastic limiting structure 400 is eliminated, it will eject the limiting insert 410 outward under the action of the reverse elastic force of the second elastic element 420, so that it separates from the roller. At this time, the restriction on the roller is eliminated, and the roller can rotate freely.

[0094] The limiting component 510 is inclinedly arranged on the base 310 and can slide relative to the base, and is used to press on the elastic limiting structure 400 to limit the elastic limiting structure. In some embodiments of this application, a pressing portion 511 is formed on one end of the limiting member 510, which presses against the elastic limiting structure 400. The pressing portion 511 presses against the outer side of the limiting insert pin to limit it; the other end is provided with a locking portion 512 for inserting and cooperating with the locking member 530.

[0095] In some embodiments, the locking part 512 is a locking hole.

[0096] In order to achieve the pressing and positioning of the limiting component on the elastic limiting structure 400, the limiting component 510 can be set to have a thinner thickness at one end, so that the pressing part 511 is formed by avoiding gaps.

[0097] In some embodiments of this application, a positioning protrusion is formed on the outer wall of the substrate, and an inclined sliding track 313 is formed on the positioning protrusion. The limiting member 510 is slidably disposed within the sliding track 313.

[0098] In some embodiments of this application, the positioning protrusion is a positioning block 312 fixedly disposed on the outer side wall of the base 310. Two positioning blocks 312 are provided and arranged obliquely and symmetrically. A receiving space for accommodating the limiting member 510 is formed between the inner side wall of the two positioning blocks 312 and the outer side wall of the base 310. A sliding track 313 is formed on the inner side wall of the two positioning blocks 312. The limiting member 510 is disposed in the receiving space and can slide along the sliding track 313.

[0099] By slidably mounting the limiting component 510 on the base 310 and arranging it at an angle, it can be ensured that after the limiting component 510 is released, it can slide relative to the base 310 and automatically fall off under its own gravity, thereby releasing the limitation on the elastic limiting structure 400.

[0100] In some other embodiments of this application, the positioning protrusion may also be formed directly on the base 310, with a slide rail formed inside it so that it can slide relative to the base 310 and fall off automatically.

[0101] In some other embodiments of this application, a sliding groove is provided on the outer wall of the substrate 310. The sliding groove is arranged at an inclination. The limiting member 510 is slidably disposed in the sliding groove. Stops extending into the sliding groove are provided on both sides of the sliding groove to prevent the limiting member 510 from disengaging from the sliding groove.

[0102] Alternatively, a recessed sliding groove can be provided on the outer side wall of the base 310. For example, the sliding groove is provided on the first base plate 314, and the sliding groove extends from the middle position to one of the side positions of the first base plate 314. The limiting member 510 is slidably disposed in the sliding groove. The sliding groove is arranged obliquely from top to bottom. The pressing part 511 at the end of the limiting member 510 presses on the elastic limiting structure 400. The pressing part 511 can be formed by bending upward relative to the body of the limiting member 510.

[0103] When the limiting element is limited, it presses against the elastic limiting structure 400 through the pressing part 511, thus limiting the elastic limiting structure 400. When the limiting element is released, it tilts and slides down relative to the base 310 under its own gravity, thereby releasing the limitation on the elastic limiting structure 400.

[0104] A power attraction device 520 is arranged on the base 310; In some embodiments of this application, the power-assisted engagement device 520 includes a protective shell 521 and an electric engagement component 522 built into the protective shell 521, wherein the electric engagement component 522 is an electromagnet.

[0105] Locking component 530 is used to lock the limiting component 510, and it can be separated from the limiting component 510 under the action of the power suction device 520; In some embodiments of this application, the locking component 530 includes a locking body 531, with an engaging portion 532 formed at one end of the locking body 531 for engaging with a power component, and a blocking component 533 detachably connected to the locking body 531 provided at the other end of the locking body 531, with an insertion portion 551 formed on the blocking component 533 for insertion into the limiting component 510.

[0106] The locking body 531 is a locking pin, and the engaging part 532 is a protruding disc formed at the end of the locking body 531. It is made of iron and is used to engage with the power engaging device 520.

[0107] The blocking component 533 is a blocking plate, which is connected and fixed between the blocking component 533 and the locking body component 531 by bolts, so as to realize the detachability between the blocking component 533 and the locking body component 531.

[0108] A first through portion for passing through the insert portion 551 and a second through portion for passing through the locking body member 531 are respectively provided on the first base plate 314 and the second base plate 315; The first through part is the first through hole, and the second through part is the second through hole.

[0109] The blocking component 533 is configured to be detachable from the locking body component 531, which facilitates the installation and removal of the locking component 530.

[0110] During assembly, the blocking component 533 is removed, and then the locking body 531 passes through the second through portion. The suction portion 532 located at one end of the locking body 531 is arranged on the outside of the placement space 311 and does not pass through the second through portion. Then the blocking component 533 is assembled, and the insertion portion 551 of the blocking component 533 passes through the first through portion to prevent the locking component 530 from coming out of the mounting base.

[0111] The insertion part 551 is an insertion positioning post arranged on the end face of the blocking member 533. Two insertion positioning posts can be provided. During positioning, one of the two insertion positioning posts is inserted into the locking hole on the limiting member 510 to limit the limiting member 510.

[0112] The first elastic element 540 is located in the placement space 311 and is arranged between the locking member 530 and the base 310. It can apply an elastic force to the locking member 530 when the power suction device 520 is separated from the locking member 530, so that it extends into the limiting member and limits it. In some embodiments of this application, the first elastic element 540 is a spring, which is sleeved on the locking body 531, with one end abutting against the blocking member 533 and the other end abutting against the inner wall of the second base plate 315.

[0113] When the power engaging device 520 is not engaged and fixed together with the engaging part 532, the first elastic element 540 is compressed between the second base plate 315 and the blocking part 533. The first elastic element 540 will apply an elastic force to the blocking part 533, causing it to drive the insert part 551 located above it to extend out to the limiting part for limiting.

[0114] When the power-engaging device 520 is energized, it engages with the engaging part 532. At this time, the insert part 551 in the locking part 530 disengages from the locking hole, and the limiting part 510 is eliminated. When the power-engaging device 520 is de-energized, it separates from the engaging part 532. Under the action of the second elastic element, the locking part 530 is inserted into the locking hole of the limiting part 510 to limit the limiting part 510.

[0115] When the power device is powered on, the power attraction device 520 attracts the locking component 530, the locking component 530 separates from the limiting component, the limiting component slides along the base to release the limiting of the elastic limiting structure 400, the elastic limiting structure 400 pops out relative to the rolling component 320 to release the limiting of the rolling component 320 when the limiting of the elastic limiting structure 400 is released, and the rolling component 320 rotates relative to the base 310 to lay the cable wrapped on it when the limiting of the elastic limiting structure 400 is released; When the power engaging device 520 is de-energized, the power engaging device 520 separates from the locking component 530. The first elastic element 540 applies a force to the locking component 530, causing it to extend into the limiting component and limit its movement. The limiting component 510 presses against the elastic limiting structure 400 and limits its movement. The elastic limiting structure 400 is inserted into the rolling component 320 and limits the rotation of the rolling component 320.

[0116] In this embodiment, the cable release device is in its initial state, the power engagement device 520 is not powered, and the locking component 530 is inserted into the locking hole of the limiting component by the elastic force of the first elastic element 540 through the first through part on the first base plate 314. The limiting component 510 presses and fixes the elastic limiting structure 400 through the pressing part 511. The limiting insert 410 of the elastic limiting structure 400 compresses the second elastic element 420 and passes through the first base plate 314 before being inserted into the limiting hole of the drum spoke to prevent the drum from rotating.

[0117] When the cable 300 release device receives the retrieval and release command, it energizes the electric suction component 522 in the control power suction device 520. At this time, the electric suction component 522 and the suction part 532 of the locking component 530 are attracted and adhered. Under the suction force of the electric suction component 522, the end of the locking component 530 disengages from the locking hole of the limiting component 510, the limiting component 510 is released, and the limiting component 510 is no longer restricted and slides downward along the base 310 under the action of gravity. The positioning component 510 slips down, and the limiting insertion part 410 is no longer limited. At this time, the second elastic element 420 arranged between the limiting insertion part 410 and the first base plate 314 pops the limiting insertion part 410 outward. The limiting insertion part 410 is separated from the limiting hole of the drum spoke plate, and the drum rotates freely. At this time, the cable wrapped on the drum is gradually unwound, and the underwater acoustic communication module connected to the cable release device floats up under the action of buoyancy. After the underwater acoustic communication module floats up, it can be retrieved.

[0118] In this embodiment, the cable release device structure connects and fixes the anchor device 600 and the cable. This ensures that even when the cable release device is activated, the cable 700 automatically opens, allowing the underwater acoustic communication module to rise. Furthermore, after the underwater acoustic communication module rises, it remains connected and fixed to the anchor device via the cable 300. Even if the underwater acoustic communication module floats to the surface due to buoyancy, the anchor device remains fixed at the bottom, preventing the underwater device from drifting aimlessly. This allows for easy location and retrieval of the underwater acoustic communication module, facilitating quick and easy recovery. Once the module is located, the cable 700 can be cut.

[0119] The cable release device in this embodiment does not require a release hook to be installed at the bottom of the equipment compartment, does not require a motor drive, and does not require additional debugging. It is easy to install, has simple control logic, and avoids situations such as inability to release the hook or jamming caused by motor and internal shaft mismatch.

[0120] This invention is installed at the bottom outside the equipment compartment and fixed to the buoyancy material protective cover by screws. The internal principle of the structure is that the locking component is driven by an electromagnet to move horizontally by 530 degrees. It is reliable and does not require additional space inside the equipment compartment, thereby increasing the overall design of the beacon's internal battery and circuit board.

[0121] In some embodiments of this application, the power suction device 520 includes a protective shell 521 and an electric suction member 522 built into the protective shell 521. A hollow cavity is formed in the protective shell 521, and the hollow cavity is filled with oil.

[0122] The protective shell 521 is made of nylon material, which is non-conductive. The hollow cavity inside is filled with oil to enhance the underwater pressure resistance of the nylon. The electric suction component 522 is installed inside the protective shell 521. An assembly gap is left between the protective shell 521 and the base. The protective shell 521 is fixedly connected to the base by bolts.

[0123] As one embodiment of the anchor device in this application: The anchor device is an anchor block, which is a concrete anchor. It is connected to the cable by a cable swivel and a cable release device. When the cable release device is activated, the anchor device is lowered to the seabed.

[0124] This embodiment also proposes a deployment method for the cross-sea-air integrated multi-functional communication equipment based on the above technical solution, including the following steps: Deploy the required multi-functional communication equipment that spans sea and air; The anchoring device is placed at the stern of the vessel being deployed, and the vessel is kept traveling in a straight line at a low speed. Wind a rope to the required depth on the cable release device; The Beidou communication module is used to deploy the recovery ring, which is then placed in the sea. The connecting cable between the Beidou communication module and the underwater acoustic communication module is lowered, and a first buoyancy material module is installed on the cable before deploying the underwater acoustic communication module. Connect the cable and anchor device at the end of the cable release device; When the deployed vessel is controlled to sail at a low speed to the preset station, the anchor device is thrown into the sea; As the anchor device descends, it pulls the Beidou communication module and the underwater acoustic communication module, which are floating on the sea surface, underwater in sequence. After the first time period, the anchor device was deployed and landed. The first time period was a few minutes later. The equipment cabin was about 60 meters underwater, and the Beidou communication module floated to the surface of the sea, completing the deployment.

[0125] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
