[0002] The ocean has enormous resources and value waiting for people to continuously develop and utilize, but currently humans have only explored about 5% of the ocean. 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 have to face the difficulties of using artificial equipment to see and see far in the deep sea, hear clearly and hear far, and difficulty in achieving communication and interconnection.

[0003] In order to create a transparent ocean and provide technical support for the development and utilization of marine resources, the existing technology uses fixed buoys or temporary buoys and other similar communication relay methods to solve the communication problems between underwater and water users (including surface users (for example, ships, surface unmanned ships, buoys, etc.), aerial platforms (for example, flying platforms (for example, airplanes, drones, balloons, airboats, etc.), sky platforms (for example, platforms applied through satellite nodes), or land platforms (for example, land base stations, shore control rooms, radio transceiver rooms, etc.)).

In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0087] In order to achieve cross-sea and air medium communication and create a transparent ocean, this application relates to a cross-sea and air medium communication relay node (hereinafter referred to as relay node), see Figures 1 to 3 , including a first relay structure 100 , a second relay structure 200 and a third relay structure 300 .

[0088] When the relay node is not working, the first relay structure 100, the second relay structure 200 and the third relay structure 300 are sequentially connected up and down to form a whole, and the whole is in the shape of a torpedo.

[0089] Specifically, the lower end of the first relay structure 100 is connected to the upper end of the second relay structure 200 through a first underwater separation device, and the lower end of the second relay structure 200 is connected to the upper end of the third relay structure 300 through a second underwater separation device.

[0090] When the relay node is deployed underwater and is in working state, see Figure 2The lower end of the first relay structure 100 is separated from the upper end of the second relay structure 200 by a first underwater separation device, and the lower end of the second relay structure 200 is separated from the upper end of the third relay structure 300 by a second underwater separation device. Figure 2 The dashed line shows the cable.

[0091] The first underwater separation device and the second underwater separation device are respectively connected using existing underwater separation devices.

[0092] The existing underwater separation device can adopt the underwater separation device disclosed in patent application number 202011314066.X and named “Underwater Separation Device” (referred to as underwater separation device A).

[0093] The lower end of the first relay structure 100 is connected to the third separation body in the underwater separation device A, the upper end of the second relay structure 200 is connected to the fourth separation body in the underwater separation device A, the lower end of the second relay structure 200 is connected to the third separation body in the underwater separation device A, and the upper end of the third relay structure 300 is connected to the fourth separation body in the underwater separation device A.

[0094] The entire contents of the subsea separation device A may be incorporated herein by reference.

[0095] The existing underwater separation device can also adopt the underwater separation device disclosed in patent application number 202011310345.9 and named “Underwater Separation Device” (referred to as underwater separation device B).

[0096] The lower end of the first relay structure 100 is connected to the second separation body in the underwater separation device B, the upper end of the second relay structure 200 is connected to the first separation body in the underwater separation device B, the lower end of the second relay structure 200 is connected to the second separation body in the underwater separation device B, and the upper end of the third relay structure 300 is connected to the first separation body in the underwater separation device B.

[0097] The entire contents of the subsea separation device B are incorporated herein by reference.

[0098] Of course, the two objects may also be separated by other underwater separation methods, which are not limited here, as long as the separation of the two objects is achieved.

[0099] The present application relates to water users, including surface users (e.g., ships, surface unmanned vessels, buoys, etc.), aerial platforms (e.g., flying platforms (e.g., airplanes, drones, balloons, airboats, etc.)), sky platforms (e.g., platforms applied via satellite nodes), or land platforms (e.g., land base stations, shore control rooms, radio transceiver rooms, etc.).

[0100] Most of the above-mentioned surface users are equipped with underwater acoustic communication devices. Therefore, they can communicate directly within the underwater acoustic communication range of the surface users equipped with underwater acoustic communication devices (see Figure 1 This part will not be described in detail in this application.

[0101] When the water users are beyond the hydroacoustic communication range of the surface users, the water users who are surface users at this time also use radio or laser signals to communicate. For the water users who use radio or laser signals to communicate, they can communicate by converting radio or laser signals into hydroacoustic signals when the first relay structure 100 floats up to the surface of the water within a preset time period and the top communication head is exposed.

[0102] The present application mainly involves using the relay nodes as described above to achieve communication across sea and air media, specifically to achieve two-way communication between radio signals or laser signals and underwater acoustic signals.

[0103] See also Figure 1 In addition to the shell, the first relay structure 100 also includes a radio or laser signal communication transceiver 110, a communication and data processing unit 120, a first underwater acoustic communication module 130 and a first power supply unit (not shown). The radio or laser signal communication transceiver 110, the first underwater acoustic communication module 120 and the first power supply unit are respectively connected to the communication and data processing unit 120 and are controlled by the communication and data processing unit 120.

[0104] The first power supply unit is used to supply power to the electrical components in the first relay structure 100 . The first power supply unit may include a first battery and a first battery management unit. The first battery management unit is used to monitor and manage the first battery.

[0105] The radio signal as described above may be a satellite communication signal or a Beidou signal, etc., and the laser signal may be a laser communication device, or a laser signal emitted by a satellite, etc.

[0106] The radio or laser signal is received by the radio or laser signal communication transceiver 110 and sent to the communication and data processing unit 120 .

[0107] After being processed by the communication and data processing unit 120 , the underwater acoustic information is sent to the first underwater acoustic communication module 130 .

[0108] After receiving the hydroacoustic information, the first hydroacoustic communication module 130 sends out a hydroacoustic signal, thereby realizing the conversion of the radio signal or the laser signal into the hydroacoustic signal.

[0109] The first underwater acoustic communication module 130 as described above is used to realize the conversion between the underwater acoustic signal and the electrical signal, and is designed by, for example, an underwater acoustic transducer and its peripheral circuits.

[0110] The hydroacoustic signal continues to be transmitted downward to the second relay structure 200 .

[0111] The second relay structure 200 includes, in addition to the housing, a deep-sea network retracting and deploying vehicle 230, an integrated control unit 220, a second hydroacoustic communication module 210, an underwater cable laying control device 240, and a second power supply unit (not shown).

[0112] The second underwater acoustic communication module 210 as described above is also used to realize the conversion between the underwater acoustic signal and the electrical signal, for example, it is designed by an underwater acoustic transducer and its peripheral circuits.

[0113] The deep-sea network retracting and deploying vehicle 230 , the second hydroacoustic communication module 210 and the second power supply unit are respectively connected to the integrated control unit 220 and are controlled by the integrated control unit 220 .

[0114] The second power supply unit is used to supply power to the electrical components in the second relay structure 200 . The second power supply unit may include a second battery and a second battery management unit. The second battery management unit is used to monitor and manage the second battery.

[0115] The deep-sea retractable network vehicle 230 adopts the deep-sea retractable network vehicle disclosed in patent application number 202111255728.5 and named "Deep-sea retractable network vehicle", and its specific structure can be incorporated into this article in its entirety by reference.

[0116] The cable of the deep-sea retractable and retractable vehicle 230 is connected to the first relay structure 100 , and its controller is a part of the integrated control unit 220 .

[0117] The second underwater acoustic communication module 210 is disposed at the upper end of the second relay structure 200 , and receives the underwater acoustic signal transmitted downward from the first relay structure 100 .

[0118] The underwater acoustic signal is processed by the second underwater acoustic communication module 210 to output underwater acoustic information, and is output to the integrated control unit 220 .

[0119] The integrated control unit 220 processes the hydroacoustic information and outputs a signal to the deep-sea retractable network vehicle 230, or to the underwater cable laying control device 240, that is, air-to-sea medium communication is realized at this time.

[0120] Under normal circumstances, the first relay structure 100 is hidden at a preset suspension depth underwater, and the preset suspension depth can be controlled by a preset instruction of the integrated control unit 220 .

[0121] Furthermore, the retracting and releasing time and interval time of the cable control command of the deep-sea retracting and releasing vehicle 230 can also be set by a preset program in the integrated control unit 220, so as to control the surfacing interval time and surfacing time of the first relay structure 100.

[0122] If one wants to change the surfacing interval and surfacing time of the first relay structure 100, it is necessary to use the communication method as described above, and change it by external instructions when the first relay structure 100 floats to the top communication head out of the water.

[0123] Of course, the preset suspension depth of the first relay structure 100 may also be set by an external instruction, but generally, the preset suspension depth will not be changed after being preset in the integrated control unit 220 .

[0124] The deep-sea cable retracting and releasing vehicle 230 receives a first cable control instruction for releasing the cable from the integrated control unit 220, and is used to release the radio or laser signal communication retracting and releasing device 110 of the first relay structure 100 to the water surface, thereby being used to send and receive radio or laser signals within the surfacing time range.

[0125] After exceeding the surfacing time range, the deep-sea cable recovery vehicle 230 receives a second cable control instruction for recovering the cable from the integrated control unit 220, which is used to pull the first relay structure 100 back to a preset suspension depth below the water surface, thereby achieving safe hiding of the first relay structure 100 and preventing it from being exposed to the water surface and being damaged or discovered.

[0126] The first cable control instruction and the second cable control instruction as described above in the present application both refer to instructions preset in the integrated control unit 220, or instructions after the preset instructions are modified by external instructions.

[0127] In addition, weapons, jammers, detectors, etc. can be installed on the top of the first relay structure 100. When the first relay structure 100 is released to the water surface, it can warn, attack, or interfere with the opponent, or it can have the above functions at the same time.

[0128] Similarly, the integrated control unit 220 and the underwater cable laying control device 240 (see Figure 1 The second relay structure 200 is connected to the integrated control unit 220, and a preset depth control instruction for setting the second relay structure 200 at a preset suspension depth is also preset in the integrated control unit 220. The cable in the underwater cable laying control device 240 is connected to the third relay structure 300.

[0129] The underwater cable laying control device 240 receives a preset depth control instruction from the integrated control unit 220 for controlling the preset suspension depth of the second relay structure 200, and the underwater cable laying control device 240 is activated.

[0130] The underwater cable laying control device 240 receives the preset depth control instruction corresponding to the fixed depth, and realizes the fixed depth of the second relay structure 200 (for example, a depth of tens to hundreds of meters underwater).

[0131] Generally, the preset suspension depth of the second relay structure 200 will not be changed after being set by the preset depth control instruction in the integrated control unit 220. Therefore, after the second relay structure 200 is set at a certain depth, it can serve as the basic point for the first relay structure 100 to rise (i.e., float up to the top communication head exposed above the water surface) and lower (i.e., be pulled back to the preset suspension depth below the water surface).

[0132] In some embodiments of the present application, the underwater cable laying control device 240 adopts the underwater cable laying control device disclosed in patent application number 202011363352.5 and named “Underwater Cable Laying Control Device”, and its specific structure can be incorporated into this document in its entirety by reference.

[0133] At this time, the preset suspension depth of the second relay structure 200 is determined by the structure of the underwater control and deployment control device 240 itself.

[0134] See also Figure 1 and Figure 2 In the middle dotted line part, when the surface user is within the underwater acoustic communication range, the surface user's underwater acoustic communication device directly sends the underwater acoustic signal to the underwater user.

[0135] When the underwater user exceeds the underwater acoustic communication range, the surface user also communicates by radio or laser signals. When the surface user communicates by radio or laser signals and floats to the top of the first relay structure 100 and the communication head emerges from the water, the information such as the position or data (such as intelligence, instructions, etc.) from the surface user can be received and directly transmitted to the underwater user for immediate use when the underwater user arrives.

[0136] The relevant data of underwater users can be directly uploaded to surface users.

[0137] See also Figure 1 and Figure 2 In the middle dotted line portion, the surface user can also communicate with the second underwater acoustic communication module 210 .

[0138] When within the underwater acoustic communication range of the surface user, the surface user can also send information (for example, information used to modify the surfacing interval and surfacing time of the first relay structure 100) to the integrated control unit 220 through the second underwater acoustic communication module 210 to achieve control of the deep-sea retractable network vehicle 230.

[0139] In addition, the integrated control unit 220 can also receive relevant real-time information about the second battery, such as the remaining power, real-time current and voltage, etc., through the second battery management unit in the second power supply unit.

[0140] The relevant real-time information can be sent to the communication and data processing unit 120 through the integrated control unit 220 via the second underwater acoustic communication module 210 and the first underwater acoustic communication module 130. After being processed by the communication and data processing unit 120, control information representing the real-time information is output, and when the first relay structure 100 floats to the top communication head and emerges from the water surface, it is transmitted back to the water surface through the radio or laser signal communication transceiver 110 to realize the monitoring of the second underwater battery.

[0141] In this way, the conversion of hydroacoustic signals into radio or laser signals is achieved, that is, sea-to-air medium communication is achieved.

[0142] Likewise, the communication and data processing unit 120 can also receive relevant real-time information about the first battery, such as the remaining power, real-time current and voltage, etc., through the first battery management unit in the first power supply unit.

[0143] After processing these relevant real-time information through the communication and data processing unit 120, control information representing these real-time information can be output, and when the first relay structure 100 floats to the top communication head and emerges from the water surface, it is transmitted back to the water surface through the radio or laser signal communication transceiver 110 to realize the monitoring of the first underwater battery.

[0144] In this way, the conversion of hydroacoustic signals into radio or laser signals is also achieved.

[0145] As described above, the various information of the first battery and the second battery can be transmitted back to the water user through the radio or laser signal communication transceiver 110 after receiving the issued instructions according to the needs of the water user, when the first relay structure 100 floats to the top communication head out of the water, that is, on-demand transmission is achieved, so that the water user can timely understand the power status of the processing device.

[0146] Generally, the third relay structure 300 consumes little power, and therefore, the power consumption of the third battery in the third power supply unit is generally not monitored.

[0147] However, as the ocean depth and ocean environment vary, in order to achieve reliable transmission of underwater acoustic signals, continue to refer to Figure 1 and Figure 2 , the relay node is also provided with a third relay structure 300.

[0148] The third relay structure 300 includes an information carrier 310 and an anchor device 320. The information carrier 310 is arranged on the anchor device 320, and the cable in the underwater cable laying control device 240 connects the information carrier 310 and the anchor device 320 (see Figure 3 ), specifically, the cable is connected to the upper end of the information carrier 310, and the lower end of the information carrier 310 is connected to the anchor device 320 through the cable.

[0149] The information carrier 310 includes an information unit 311 , which includes a third underwater acoustic communication module 3112 and a third power supply unit (not shown).

[0150] The third underwater acoustic communication module 3112 as described above is used to realize the conversion between underwater acoustic signals and electrical signals, and is designed, for example, by an underwater acoustic transducer and its peripheral circuits.

[0151] The third power supply unit is used to supply power to the power-consuming components in the third relay structure 300 . The third power supply unit may include a third battery and a third battery management unit. The third battery management unit is used to monitor and manage the third battery.

[0152] The third underwater acoustic communication module 3112 is disposed at the upper end of the information carrier 310 , and receives information sent by the user on water through the first underwater acoustic communication module 130 in the first relay structure 100 .

[0153] When the underwater users are beyond the underwater acoustic communication range, the underwater users who are surface users at this time also use radio or laser signals to communicate. For the underwater users who use radio or laser signals to communicate, they will float to the top of the water with the help of the first relay structure 100 and when the top communication head is exposed above the water surface, they will communicate through the conversion of radio or laser signals and underwater acoustic signals.

[0154] Therefore, when the third underwater acoustic communication module 3112 is provided, the third underwater acoustic communication module 3112 receives the underwater acoustic signal forwarded by the first underwater acoustic communication module 130 in the first relay structure 100 .

[0155] When the first relay structure 100 floats up to the top communication head out of the water, the radio or laser signal communication transceiver 110 can receive information such as the location or data (such as intelligence, instructions, etc.) from the user on the water. After being processed by the communication and data processing unit 120, the first underwater acoustic communication module 130 is controlled to output the corresponding underwater acoustic signal. The underwater acoustic signal is received by the third underwater acoustic communication module 130 and output to the underwater user for immediate use when the underwater user arrives.

[0156] That is, air-to-sea medium communication is achieved.

[0157] The underwater user can also upload the relevant data of the underwater user to the radio or laser signal communication transceiver 110 through the third underwater acoustic communication module 3112, the first underwater acoustic communication module 130 and the communication and data processing unit 120 in sequence, and then upload it to the surface user.

[0158] The underwater user can also send information (for example, information used to modify the surfacing interval and surfacing time of the first relay structure 100) to the integrated control unit 220 of the second relay structure 200 through the third relay structure 300 and the first relay structure 100 in sequence to achieve control of the deep-sea retractable network vehicle 23.

[0159] That is, to achieve communication between the sea, air and sea media.

[0160] It should be noted that when the underwater acoustic communication range is beyond the surface users, the water users who are surface users at this time also use radio or laser signals to communicate. For the water users who use radio or laser signals to communicate, the first relay structure 100 is used as a transit node to communicate between the sea and air media.

[0161] That is, the mutual communication between the first relay structure 100 and the second relay structure 200 is used to modify the surfacing interval and surfacing time of the first relay structure 100, the information monitoring of the first battery / the second battery, etc., as described above.

[0162] The mutual communication between the first relay structure 100 and the third relay structure 300 is used for communication between surface users and underwater users when the communication range is beyond the hydroacoustic communication range of surface users and surface users (such as aerial platforms, sky platforms, land platforms, etc.) that communicate using radio or laser signals.

[0163] In the present application, since the first underwater acoustic communication module 130 and the third underwater acoustic communication module 3112 communicate with each other, and the first underwater acoustic communication module 130 and the second underwater acoustic communication module 210 communicate with each other, an information storage unit A can be set in the first relay structure 100 or an information access unit B can be set in the second relay structure 200.

[0164] When the information access unit A is disposed in the first relay structure 100 , the information access unit A is connected to the communication and data processing unit 120 .

[0165] When the information access unit B is arranged in the second relay structure 200, the information access unit B is connected to the integrated control unit 220. In this application, see Figure 2 An information access unit 3114 may also be provided in the third relay structure 300 , and the information storage unit 3114 is connected to the information processing unit 3113 .

[0166] The information access unit A / B / 3114 is used to store data from surface users (e.g., location, intelligence, instructions, etc.) for use by delayed underwater users when activating the relay node, ensuring underwater safety when underwater users extract information.

[0167] The underwater user can also store relevant data of the underwater user in the information access unit A / B / 3114. When within the underwater acoustic communication range of the surface user, the surface user activates the relay node to retrieve the required information.

[0168] When the underwater acoustic communication range of the surface users is exceeded, the surface users at this time also communicate using radio or laser signals. For the surface users using radio or laser signals for communication, when the first relay structure 100 floats up to the surface of the water within a preset time period and the top communication head is exposed, the relay node can be activated to retrieve the required information and convert it into a radio or laser signal to send back or upload.

[0169] by Figure 2 The information access unit 3114 is set as an example for explanation.

[0170] When the underwater user exceeds the underwater acoustic communication range of the surface user, the surface user also uses radio or laser signals to communicate. For the surface user using radio or laser signals to communicate, when the first relay structure 100 floats up to the surface of the water within a preset time period until the top communication head emerges from the water, the surface user can store the data in the information access unit 3114 through the first relay structure 100 and the third underwater acoustic communication module 3112.

[0171] When the underwater user arrives later, the third relay structure 300 is activated to retrieve the required information from the information access unit 3114.

[0172] When the underwater user extracts information and sends it to the surface user, if the surface user is a surface user and is within its underwater acoustic communication range, the underwater user directly uploads it to the surface user.

[0173] If the water acoustic communication range of the surface user is exceeded, the surface user at this time also uses radio or laser signals to communicate. For the surface user using radio or laser signals to communicate, when the first relay structure 100 has not floated to the top communication head above the water surface, the information can be stored in the information access unit 3114. After the first relay structure 100 floats to the top communication head above the water surface, the marine information processing device is activated to retrieve the required information.

[0174] In this way, when the first relay structure 100 floats up to the top communication head exposed above the water surface to transmit information back to the user on the water, the underwater user has already left the original location to ensure his safety. After sending the information, the first relay structure 100 is also pulled back by the deep-sea network vehicle 230 and hidden to the preset suspension depth under the water surface.

[0175] When the delayed underwater user arrives, the underwater user first needs to send an activation instruction to the information carrier 310 to activate the information carrier 310, and then the information in the information access unit 3114 can be extracted.

[0176] When, for example, the communication and navigation of an aerial platform, a land platform or an aerial platform are restricted, the first relay structure 100 replaces its function through information conversion when it floats to the top communication head above the water surface. The communication method is the same as that described above and is not limited here.

[0177] When the third relay structure 300 is deployed underwater, when it sinks to a certain depth (this depth can be preset), the information carrier 310 is separated from the anchor device 320, and the anchor device 320 is sunk to the seabed to achieve the anchoring of the relay node.

[0178] In order to realize the above-mentioned design between the information carrier 310 and the anchor device 320, see Figures 4 to 11 Give a description.

[0179] In order to enable the information carrier 310 to be removed from the anchor device 320 , the information carrier 310 is designed as follows.

[0180] The information carrier 310 includes not only an information unit 311 but also a floating body 312 , wherein the information unit 311 includes a housing 3111 .

[0181] As mentioned above, the third underwater acoustic communication module 3112, the information processing unit 3113, the information access unit 3114 and the third power supply unit are all placed in the housing 3111, wherein the third underwater acoustic communication module 3112 needs to be exposed to contact with water.

[0182] See also Figures 4 to 7 The shell 3111 and the third underwater acoustic communication module 3112, the information processing unit 3113 and the third power supply unit therein form a whole, which is torpedo-shaped and has a circular cross-section.

[0183] The shell 3111 is fixed in the floating body 312 . When the shell 3111 is fixed in the floating body 312 , the third underwater acoustic communication module 3112 arranged at the top should extend out from the floating body 312 .

[0184] The housing 3111 is fixedly mounted inside the float 312 in the following manner.

[0185] A through hole 313 is opened in the floating body 312 along the water depth direction, and the shell 3111 is inserted into the through hole 313 . At this time, the upper end and the lower section of the shell 3111 both extend out of the floating body 312 .

[0186] A plurality of annular grooves (not shown) are provided on the inner wall of the through hole 313 along the water depth direction. The shell 3111 is sleeved on a plurality of annular rings 314, and each annular ring 314 is placed at a corresponding annular groove, as follows, so as to limit the shell 3111 from moving up and down in the float 312, and prevent the shell 3111 from escaping from the float 312, thereby achieving the fixation of the shell 3111 in the float 312.

[0187] In order to satisfy the redundancy design, two information units 311 and 311 ′ are arranged in parallel in the floating body 312 , and the design of each information unit 311 / 311 ′ is the same.

[0188] The cable in the underwater cable deployment control device 240 is connected to the upper end of the housing 3111, and the lower end of the housing 3111 is connected to the anchor device 320 through the cable.

[0189] As described above, the information carrier 310 is arranged on the anchor device 320. Since the shell 3111 together with the internal components (the third underwater acoustic communication module 3112, the information processing unit 3113 and the third power supply unit) and the float 312 are fixed together, the information carrier 310 is placed on the anchor device 320, and specifically the float 312 is placed in the anchor shell (not marked) of the anchor device 320.

[0190] Before reaching a certain depth, the information carrier 310 is stable in the anchor shell because its own weight is greater than its buoyancy. When the buoyancy of the information carrier 310 is greater than its own weight, the information carrier 310 escapes from the anchor shell and floats.

[0191] The floating body 312 has positive buoyancy consistent with the first relay structure 100 and the second relay structure 200 , and the anchor device 320 has negative buoyancy.

[0192] The anchor device 320 as described above can refer to the anchor device disclosed in the existing patent application No. 202111254747.6, entitled “An anchor device” (referred to as anchor device A), and its specific structure can be incorporated herein by reference in its entirety.

[0193] The anchor device 320 described herein may be an anchor device A, and the anchor housing is the housing of the anchor device A.

[0194] An annular boss may be provided on the inner wall of the anchor shell to support the information carrier 310 , and a connector (such as a lug with a through hole, a connecting rod, a connecting bump, etc.) for connecting the cable may be provided inside the anchor shell.

[0195] The cable in the underwater cable deployment control device 240 is connected to the upper end of the housing 3111, and the lower end of the housing 3111 is connected to the connecting piece of the anchor device 320 through the cable.

[0196] When sinking to a certain depth, the buoyancy of the information carrier 310 is greater than its own weight, and the information carrier 310 escapes from the anchor housing and floats, and its floating height is controlled by the length of the cable.

[0197] Afterwards, the anchor device 320 can achieve the function of gripping and fixing the ground as described in the anchor device A in the prior art.

[0198] Alternatively, the anchor device 320 may also be implemented using other structures.

[0199] See also Figures 8 to 11 The anchor device 320 has an anchor housing, an anchor bottom plate 323, an anchor base 324, a pair of flukes, an anchor rod 326, an anchor chain 327 and a pair of sealing sliding assemblies.

[0200] The pair of flukes includes a first fluke 325 and a second fluke 325', and the pair of sealing sliding assemblies includes a first sealing sliding assembly 328 and a second sealing sliding assembly 328'. The first sealing sliding assembly 328 corresponds to the first fluke 325, and the second sealing sliding assembly 328' corresponds to the second fluke 325'.

[0201] The anchor shell is a cylindrical structure and encloses a cavity, which is connected from top to bottom, that is, the upper end has a top opening and the lower end has a bottom opening.

[0202] The upper end of the information carrier 310 is exposed from the top opening.

[0203] The anchoring bottom plate 323 is used to block the bottom opening, and the anchoring bottom plate 323 may have a water flow passage portion (not shown) for water to flow through.

[0204] The anchor base 324 is located in the cavity and is placed on the anchor base plate 323 .

[0205] A pair of flukes are fixed on the anchor base 324 . In some embodiments of the present application, the first fluke 325 and the second fluke 325 ′ are symmetrically arranged on the anchor base 324 .

[0206] The arrangement of the flukes 325 / 325 ′ enhances the ground-gripping capability of the anchor device 320 .

[0207] The anchor rod 326 is rotatably connected between the first anchor claw 325 and the second anchor claw 325', so that the first anchor claw 325 and the second anchor claw 325' are inserted into the seabed at a suitable angle.

[0208] In some embodiments of the present application, the anchor rod 326 can be connected to the first anchor claw 325 and the second anchor claw 325' respectively through the rotating shaft 329, that is, the first end of the rotating shaft 329 is fixedly connected to the first anchor claw 325, the second end of the rotating shaft 329 is fixedly connected to the second anchor claw 325', and the bottom end of the anchor rod 326 is rotatably connected to the rotating shaft 329.

[0209] See also Figures 8 to 11 The anchor base 324 includes a first anchor plate 3241 and a second anchor plate 3242 arranged in parallel, a first anchor claw 325 is clamped between one end A of the first anchor plate 3241 and an end A' of the second anchor plate 3242 corresponding to the one end A, and a second anchor claw 325' is clamped between the other end B of the first anchor plate 3241 and the other end B' of the second anchor plate 3242 corresponding to the other end B.

[0210] At the same time, the middle part a' of the first anchor plate 3241 between one end A and the other end B and the middle part b' of the second anchor plate 3242 between one end A' and the other end B' constitute a limiting part of the anchor rod 326 in the rotation direction, which is used to limit the rotation angle of the anchor rod 326.

[0211] Alternatively, anchor rod 326 can be connected to anchor base 324 via rotating shaft 329, so that anchor rod 326 is rotatably connected between first anchor claw 325 and second anchor claw 325', that is, one end of rotating shaft 329 is fixedly connected to a portion of anchor base 324 located on the same side of first anchor claw 325 and second anchor claw 325', and the other end is fixedly connected to a portion of anchor base 324 located on the other side of first anchor claw 325 and second anchor claw 325'.

[0212] One end of the anchor chain 327 is connected to the anchor rod 326, and the other end is connected to the anchor housing. The length of the anchor chain 327 can be designed as needed.

[0213] The anchor housing may be provided with a connecting piece for connecting the anchor chain 327 .

[0214] In some embodiments of the present application, the anchor device 320 further includes a partition plate 3221 for dividing the cavity of the anchor housing into a first cavity and a second cavity (ie, a lower cavity C2) formed in an upper and lower manner.

[0215] See also Figure 5 The float 312 is located in the first cavity and can be used to support the information carrier 310 by providing an annular boss 3211 on the inner wall of the first cavity.

[0216] See also Figure 8 A connector is provided in the first cavity below the float 312 and used to connect the cable. The connector may be a connecting cross bar 3222 located on the inner side wall of the first cavity, or a connecting block located on the inner side wall of the first cavity.

[0217] The anchor base 324, the anchor rod 326, the anchor chain 327, the first anchor claw 325 and the second anchor claw 325' are all located in the second cavity, and the bottom opening of the anchor housing is the bottom opening of the second cavity.

[0218] See also Figure 8A lug 3225 is provided on the bottom surface of the partition plate 3221 facing the second cavity, and the other end of the anchor chain 327 is connected to the lug 3225 .

[0219] Specifically, a connection hole is provided on the lug 3225, and the other end of the anchor chain 327 is fixedly connected to the connection hole by a lock.

[0220] In some embodiments of the present application, see Figures 8 to 11 The first anchor claw 325 and the second anchor claw 325' are placed flat on the anchoring bottom plate 323, occupying a small space, thereby reducing the space of the second cavity, which is conducive to the miniaturization and compact design of the product.

[0221] See also Figure 5 and Fig.10 The first sealing sliding assembly 328 is sealingly assembled in the first anchor claw 325, and the free end 3284 extending beyond the first anchor claw 325 extends into the first side wall through hole 3223 of the anchor shell, specifically into the first side wall through hole 3223 of the second cavity.

[0222] The second sealing sliding assembly 328' is sealingly assembled in the second fluke 325', and the free end 3284' extending beyond the second fluke 325' extends into the second side wall through hole 3223' of the anchor housing, specifically into the second side wall through hole 3223' of the second cavity.

[0223] When the anchor device 320 is in a non-working state, the first sealing sliding assembly 328 and the second sealing sliding assembly 328 ′ are respectively clamped and fixed to the anchor housing.

[0224] When the anchor device 320 is located at a preset depth underwater, the first sealing sliding assembly 328 and the second sealing sliding assembly 328 ′ are separated from the anchor housing under the action of water pressure.

[0225] Specifically, the anchor housing is connected to the side wall of the anchor housing, specifically to the side wall of the second cavity, through a connecting assembly.

[0226] The connection assembly includes a first connection member 3231 , a second connection member 3232 and an ear hook 3233 .

[0227] The first connecting member 3231 is an L-shaped plate, including a first horizontal plate and a first vertical plate. The first horizontal plate is fixedly connected to the anchor base plate 323. The first vertical plate is arranged between the free end 3284 of the first sealing sliding assembly 328 extending beyond the first anchor claw 325 and the first side wall through hole 3223 of the anchor shell, and the free end 3284 of the first sealing sliding assembly 328 extending beyond the claw of the first anchor 325 extends into the first side wall through hole 3223 of the anchor shell through the first through hole opened in the first vertical plate.

[0228] The second connecting member 3232 is an L-shaped plate, including a second horizontal plate and a second vertical plate. The second horizontal plate is fixedly connected to the anchor base plate 323. The second vertical plate is arranged between the free end 3284' of the second sealing sliding assembly 328' extending beyond the second anchor claw 325' and the second side wall through hole 3223' of the anchor shell, and the free end 3284' of the second sealing sliding assembly 328' extending beyond the second anchor claw 325' extends into the second side wall through hole 3223' of the anchor shell through the second through hole opened in the second vertical plate.

[0229] See also Figures 8 to 10 In order to stabilize the anchoring base plate 323, an ear hook 3233 is also provided, and the ear hook 3233, the first connecting member 3212 and the second connecting member 3232 form a triangle pattern.

[0230] One end of the ear hook 3233 is fixedly connected to the anchor base plate 323, and the free end is hung on a protrusion (not shown) on the inner side wall of the anchor housing.

[0231] The free end of the ear hook 3233 is hung on the protrusion in such a manner that the ear hook 3233 and the protrusion can be easily separated when the first sealing sliding assembly 328 and the second sealing sliding assembly 328' are separated from the anchor housing under the action of water pressure.

[0232] Specifically, the ear hook 3233 can be arranged in a Z shape, including a first transverse portion, a vertical portion connected to the first transverse portion, and a second transverse portion connected to the vertical portion, wherein the extension directions of the first transverse portion and the second transverse portion both extend away from the vertical portion.

[0233] The first transverse portion is mounted on the protrusion, and the second transverse portion is fixed to the anchoring base plate 323 .

[0234] The first sealing sliding assembly 328 and the second sealing sliding assembly 328 ′ have the same structure, so the structure of the first sealing sliding assembly 328 is taken as an example for description.

[0235] In order to assemble the first sealing sliding assembly 328 onto the first anchor claw 325 , a limiting groove 3251 is provided corresponding to the first anchor claw 325 .

[0236] See also Fig.10 The first sealing sliding assembly 328 includes an elastic member 3281 and a plunger 3282 .

[0237] The elastic member 3281 is located in the limiting groove 3251, and one end thereof abuts against the bottom wall of the limiting groove 3251; the plunger 3282 is sealingly and slidably disposed in the limiting groove 3251, and extends beyond the first anchor claw 325, that is, a portion of the plunger 3282 is placed in the limiting groove 3251, slides relative to the limiting groove 3251, and seals the limiting groove 3251 while sliding, and the other end of the elastic member 3281 abuts against one end of the plunger 3282 located in the limiting groove 3251.

[0238] In the present application, the elastic member 3281 is a spring, which is used to provide elastic force to the plunger 3282 in a non-working state, so that it clamps the anchor housing through the first connecting member 3231, and can be compressed and deformed in a working state.

[0239] Alternatively, the elastic member 3281 is any deformable element that can provide elastic restoring force, such as silicone.

[0240] See also Fig.10 and Fig.11 The free end 3284 of the plunger 3282 extending beyond the first cat claw 325 extends into the first through hole of the first vertical plate in the first connecting member 3231 and further extends into the first side wall through hole 3223 of the anchor housing.

[0241] When the relay node is deployed underwater, the water pressure increases with the depth, and the water pressure acts on the free end 3284 of the plunger 3282 (see Fig.11 The plunger 3282 moves toward the elastic member 3281 and squeezes the elastic member 3281 until the plunger 3282 is moved by water pressure to the point where its free end 3284 is disengaged from the first side wall through hole 3223 of the anchor housing.

[0242] The same is true for the second sealing sliding assembly 328', see Fig.11 In the direction indicated by the left arrow, the water pressure moves the plunger of the second sealing sliding assembly 328' until its free end 3284' is disengaged from the second side wall through hole 3223' of the anchor housing.

[0243] Since the other fulcrum of the anchoring base plate 323 is connected to the anchor housing through the ear hook 3233, when the plunger 3282 of the first sealing sliding assembly 328 and the plunger of the second sealing sliding assembly 328' are separated from the anchor housing, the anchoring base plate 323 together with the anchor base 324, the anchor rod 326, the anchor chain 327 and the pair of anchor claws 325 / 325' all sink, see Fig. 9 .

[0244] During the continued sinking process, the water pressure continues to act on the plunger 3282 of the first sealing sliding assembly 328, causing the plunger 3282 to continue to move toward the elastic member 3281 and squeeze the elastic member 3281 until the water pressure causes the plunger 3282 to move to the point where its free end 3284 is disengaged from the first through hole of the first vertical plate in the first connecting member 3231; and also acts on the plunger of the second sealing sliding assembly 328', causing the plunger to continue to move toward the elastic member and squeeze the elastic member until the water pressure causes the plunger to move to the point where its free end 3284' is disengaged from the second through hole of the second vertical plate in the second connecting member 3232.

[0245] At this time, the whole consisting of the anchor base 324, the anchor rod 326, the anchor chain 327 and the pair of anchor claws 325 / 325' is separated from the anchor base plate 323, so that the anchor claws 325 / 325' are fixed to the ground by gripping.

[0246] In order to seal the limiting groove 3251 and prevent water from entering the cavity where the elastic member 3281 is located, see Fig.11 At least one annular groove 3283 is formed on the outer side wall of the portion of the plunger 3282 that extends into the limiting groove 3251 , and a sealing ring (not shown) is installed in each annular groove 3283 .

[0247] The sealing ring seals the gap between the plunger 3282 and the inner wall of the limiting groove 3251, and at the same time, the plunger 3282 can drive each sealing ring to slide in the limiting groove 3251 to achieve sliding sealing.

[0248] See also Figure 4 , Figure 5 and Figure 8 In some embodiments of the present application, the anchor shell includes a first shell 321 and a second shell 322 connected up and down.

[0249] The first housing 321 forms a first accommodation space.

[0250] The second shell 322 has a partition plate 3221 therein, which divides the second shell into an upper cavity C1 and a lower cavity C2. The first accommodating space and the upper cavity C1 form the first cavity as described above, and the lower cavity C2 is the second cavity as described above.

[0251] An annular boss 3211 is formed on the inner side wall of the first accommodating space for supporting the floating body 312 ; the connecting cross bar 3222 as described above may be disposed on the inner side wall of the upper cavity C1 .

[0252] The first shell 321 and the second shell 322 are connected via an interface portion, for example, the interface portion is a connecting flange.

[0253] That is, the lower end of the first shell 321 has a first interface portion 3212 , and the upper end of the second shell 322 has a second interface portion 3224 , and the first interface portion 3212 and the second interface portion 3224 are adapted to be connected.

[0254] In some embodiments of the present application, the first interface portion 3212 is a first interface flange, and the second interface portion 3224 is a second interface flange.

[0255] A group of first interface connection holes 3213 is opened on the side wall of the first interface flange, and a group of second interface connection holes 3226 is opened on the side wall of the second interface flange. The first interface connection holes 3213 and the second interface connection holes 3226 are fixed by corresponding connection using screws.

[0256] By designing the anchor housing to be the first housing 321 and the second housing 322 as described above, the anchor device 320 can be counterweighted and the anchor housing can be easier to assemble.

[0257] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for a person skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to replace some of the technical features therein by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions claimed to be protected by the present invention.
