In order to implement communication between cross-sea and air-space media and create a transparent sea, the present application relates to a cross-sea and air-space media communication relay node (hereinafter referred to as a relay node), and referring to fig. 1 to 3, the relay node includes a first relay structure 100, a second relay structure 200, and a third relay structure 300.

When the relay node is not in operation, 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 a torpedo shape.

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.

When the relay node is deployed underwater and in operation, the 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, see fig. 2, 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, the dashed lines in fig. 2 showing cables.

The first underwater separation device and the second underwater separation device are respectively connected by the existing underwater separation device.

An existing underwater separation device may employ an underwater separation device (denoted as underwater separation device a) as disclosed in patent application No. 202011314066.X, entitled "underwater separation device".

The lower end of the first relay structure 100 is connected with the third separation body in the underwater separation device a, the upper end of the second relay structure 200 is connected with the fourth separation body in the underwater separation device a, the lower end of the second relay structure 200 is connected with the third separation body in the underwater separation device a, and the upper end of the third relay structure 300 is connected with the fourth separation body in the underwater separation device a.

Subsea separation device a may be incorporated by reference herein in its entirety.

The existing underwater separation device can also adopt an underwater separation device (recorded as an underwater separation device B) disclosed in patent application No. 202011310345.9 and named as an underwater separation device.

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

Subsea separation device B may be incorporated by reference herein in its entirety.

Of course, the separation mode of the two objects can also adopt other underwater separation modes, and the separation mode is not limited here as long as the separation of the two objects is realized.

The present application relates to water users, including surface users (e.g., ships, surface drones, buoys, etc.), airborne platforms (e.g., flying platforms (e.g., airplanes, drones, balloons, airships, etc.), airborne platforms (e.g., platforms applied through satellite nodes), or land platforms (e.g., land based base stations, land based control rooms, radio transceiver rooms, etc.).

Most of the above-mentioned water users are equipped with the underwater acoustic communicator, so that the communication can be directly performed within the underwater acoustic communication range of the water user with the underwater acoustic communicator (see the dotted line part in fig. 1), which is not described in detail in this application.

When the underwater acoustic communication range of the water surface user is exceeded, the water surface user, which is the water surface user, also uses the radio or laser signal for communication, and for the water surface user which uses the radio or laser signal for communication, the communication can be performed through conversion between the radio or laser signal and the underwater acoustic signal when the first relay structure 100 floats out to the surface where the top communication head is exposed out of the water within a preset time period.

The application mainly relates to the relay node which is adopted to realize communication between cross-sea and air media, in particular to bidirectional communication between radio signals or laser signals and underwater acoustic signals.

Referring to fig. 1, the first relay structure 100 includes, in addition to a housing, 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), and 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 controlled by the communication and data processing unit 120.

The first power supply unit is used to supply power to the electric components in the first relay structure 100, and may include a first battery and a first battery management unit for monitoring and managing the first battery.

The radio signal may be a satellite communication signal or a beidou signal, and the laser signal may be a laser communication device or a laser signal emitted by a satellite.

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.

Processed by the communication and data processing unit 120, and then sent to the underwater acoustic information to the first underwater acoustic communication module 130.

The first underwater acoustic communication module 130 sends out an underwater acoustic signal after receiving the underwater acoustic information, thereby realizing conversion from a radio signal or a laser signal to the underwater acoustic signal.

The first underwater acoustic communication module 130 is used for converting the underwater acoustic signal and the electric signal, and is designed by, for example, an underwater acoustic transducer and its peripheral circuit.

The underwater acoustic signal continues down to the second relay structure 200.

The second relay structure 200 includes, in addition to the housing, a deep sea reel 230, an integrated control unit 220, a second underwater acoustic communication module 210, an underwater cable deployment control device 240, and a second power supply unit (not shown).

The second underwater acoustic communication module 210 as described above is also used for converting between underwater acoustic signals and electric signals, and is designed by an underwater acoustic transducer and its peripheral circuits, for example.

The deep sea release and retraction trolley 230, the second underwater acoustic communication module 210 and the second power supply unit are respectively connected with the integrated control unit 220 and controlled by the integrated control unit 220.

The second power supply unit is used to supply power to the electric components in the second relay structure 200, and may include a second battery and a second battery management unit for monitoring and managing the second battery.

The deep sea reeling and unreeling reel 230 employs a deep sea reeling and unreeling reel disclosed in patent application No. 202111255728.5 entitled "deep sea reeling and unreeling reel", the specific structure of which is incorporated herein by reference in its entirety.

The cable of the deep sea winding and unwinding vehicle 230 is connected to the first relay structure 100, and its controller is a part of the integrated control unit 220.

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 downloaded from the first relay structure 100.

The underwater acoustic signal is processed by the second underwater acoustic communication module 210, and then outputs the underwater acoustic information to the integrated control unit 220.

The integrated control unit 220 processes the underwater acoustic information, and outputs a signal to the deep sea retraction and release trolley 230 or the underwater cable deployment and release control device 240, that is, the air-to-sea medium communication is realized at this time.

Normally, the first relay structure 100 is hidden under water by a predetermined floating depth, which can be controlled by a predetermined command of the integrated control unit 220.

In addition, the retraction time and the interval time of the cable control command of the deep sea retraction/deployment trolley 230 may be set by a preset program in the integrated control unit 220, so as to control the floating interval time and the floating time of the first relay structure 100.

In order to change the floating interval time and floating time of the first relay structure 100, it is necessary to change the floating interval time and floating time by an external command when the first relay structure 100 floats up to the top communication head exposed surface by the communication method as described above.

Of course, the preset levitation depth of the first relay structure 100 may also be set by an external command, but in general, after being preset in the integrated control unit 220, it will not be changed.

The deep sea winding and unwinding vehicle 230 receives a first cable control command for releasing the cable from the integrated control unit 220, and releases the radio or laser signal communication winding and unwinding device 110 of the first relay structure 100 to the water surface, thereby transmitting and receiving radio or laser signals within the floating time range.

After exceeding the floating time range, the deep-sea winding reel 230 receives a second rope control command for rope recovery from the integrated control unit 220, and is configured to pull the first relay structure 100 back to the preset floating depth below the water surface, so as to safely hide the first relay structure 100 and avoid being damaged or discovered due to exposure to the water surface.

The first rope control command and the second rope control command as described above both refer to commands preset in the integrated control unit 220 in the present application, or commands in which the preset commands are modified by external commands.

Further, a weapon, a jammer, a detector, or the like may be attached to the tip of the first relay structure 100, and when the first relay structure 100 is released to the water surface, an early warning, a striking, or an interference to an opponent may be performed, or the above functions may be provided at the same time.

Similarly, the integrated control unit 220 is connected to the underwater cable laying control device 240 (shown by a dashed and dotted line in fig. 1), and a preset depth control command for setting the depth of the second relay structure 200 to a preset levitation depth is also preset in the integrated control unit 220. The cables in the underwater cable laying control device 240 are connected to the third relay structure 300.

The underwater cable laying control device 240 receives a preset depth control command for controlling the preset floating depth of the second relay structure 200 from the integrated control unit 220, and the underwater cable laying control device 240 operates. .

The underwater cable laying control device 240 receives the issued preset depth control command corresponding to the fixed depth, and realizes the fixed depth of the second relay structure 200 (for example, the depth of tens of meters to hundreds of meters below the water).

Generally, the preset levitation depth of the second relay structure 200 is not changed after being set by the preset depth control command in the integrated control unit 220, and therefore, the second relay structure 200 after being set can be used as a base point for the first relay structure 100 to ascend (i.e., to ascend to the top communication head out of the water) and descend (i.e., to retract to the preset levitation depth under the water).

In some embodiments of the present application, the underwater cable deployment control device 240 employs an underwater cable deployment control device disclosed in patent application No. 202011363352.5 entitled "underwater cable deployment control device," the specific structure of which is incorporated herein by reference in its entirety.

At this time, the preset levitation depth of the second relay structure 200 is determined by the structure of the underwater control deployment control device 240 itself.

Referring to fig. 1 and the dotted line part in fig. 2, when the underwater acoustic communication range of the water surface user is within, the underwater acoustic communicator of the water surface user directly sends an underwater acoustic signal to the underwater user.

When the underwater acoustic communication range of the user on the water surface is exceeded, the user on the water surface also communicates by using a radio or laser signal, and when the first relay structure 100 floats upwards to the top end communication head to expose the water surface, the user on the water surface communicating by using the radio or laser signal can receive information such as position or data (such as information, instructions and the like) from the user on the water surface and directly download the information to the user under the water so as to be used immediately when the user under the water comes instantly.

The relevant data of the underwater user can be directly uploaded to the overwater user.

Referring to fig. 1 and the dashed portion of fig. 2, the surface user is also able to communicate with the second underwater acoustic communication module 210.

When the underwater acoustic communication range of the surface user is within the underwater acoustic communication range, the surface user may also transmit information (for example, information for modifying the floating interval time and the floating time of the first relay structure 100) to the integrated control unit 220 through the second underwater acoustic communication module 210, so as to control the deep sea winding and unwinding cart 230.

In addition, the integrated control unit 220 can also receive related instant information about the second battery, such as the remaining capacity, the instant current and voltage, etc., through the second battery management unit in the second power supply unit.

The related instant messages can be sent to the communication and data processing unit 120 through the second underwater acoustic communication module 210 and the first underwater acoustic communication module 130 by the integrated control unit 220, the control messages representing the instant messages are output after being processed by the communication and data processing unit 120, and the control messages are transmitted back to the water surface through the radio or laser signal communication transceiver 110 when the first relay structure 100 floats upwards to the position where the top communication head is exposed out of the water surface, so that the monitoring of the underwater second battery is realized.

Thus, the conversion of the underwater acoustic signal to a radio or laser signal, i.e., the sea-to-air medium communication, is realized.

Likewise, the communication and data processing unit 120 can also receive related instant information about the first battery, such as remaining capacity, instant current voltage, etc., through the first battery management unit in the first power supply unit.

After the related instant messages are processed by the communication and data processing unit 120, control messages representing the instant messages are output, and when the first relay structure 100 floats upwards to the position where the top communication head is exposed out of the water surface, the control messages are transmitted back to the water surface through the radio or laser signal communication transceiver 110, so that the monitoring of the underwater first battery is realized.

In this way, conversion of the underwater acoustic signal into a radio or laser signal is also achieved.

After receiving the issued command according to the requirement of the user on water, the information of the first battery and the second battery can be returned to the user on water through the radio or laser signal communication transceiver 110 when the first relay structure 100 floats to the position where the top communication head is exposed out of the water, that is, the return on demand is realized, so that the user on water can timely master the electric quantity condition in the processing device.

In general, the third relay configuration 300 consumes less power, and therefore, the power consumption of the third battery in the third power supply unit is not generally monitored.

However, the marine environment varies with the depth of the ocean water, and therefore, in order to achieve reliable transmission of underwater acoustic signals, with continued reference to fig. 1 and 2, the relay node is further provided with a third relay structure 300.

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

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

The third underwater acoustic communication module 3112 is used for converting underwater acoustic signals and electric signals, and is designed by, for example, an underwater acoustic transducer and peripheral circuits thereof.

The third power supply unit is used to supply power to the electric components in the third relay structure 300, and may include a third battery and a third battery management unit for monitoring and managing the third battery.

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.

When the underwater acoustic communication range of the water surface user is exceeded, the water surface user, which is the water surface user, also uses the radio or laser signal for communication, and for the water surface user who uses the radio or laser signal for communication, the water surface user floats to the position where the top end communication head is exposed by means of the first relay structure 100, and the communication is performed through the conversion of the radio or laser signal and the underwater acoustic signal.

Therefore, when the third underwater acoustic communication module 3112 is set, the third underwater acoustic communication module 3112 receives the underwater acoustic signal forwarded through the first underwater acoustic communication module 130 in the first relay structure 100.

When the first relay structure 100 floats to the top end communication head exposing the water surface, the radio or laser signal communication transceiver 110 can receive the position or data (such as information, instructions, etc.) information from the user on the water surface, and after being processed by the communication and data processing unit 120, the communication and data processing unit controls the first underwater acoustic communication module 130 to output the underwater acoustic signal corresponding to the position or data, and the underwater acoustic signal is received by the third underwater acoustic communication module 130 and output to the user under the water, so that the user under the water can use the underwater acoustic signal immediately when the user comes.

I.e. to enable air-to-sea medium communication.

The underwater user may also upload the related data of the underwater user to the radio or laser signal communication transceiver 110 sequentially through the third underwater acoustic communication module 3112, the first underwater acoustic communication module 130 and the communication and data processing unit 120, and then upload the data to the above-water user.

The underwater user may also send information (for example, information for modifying the floating interval time and floating time of the first relay structure 100) to the integrated control unit 220 of the second relay structure 200 sequentially through the third relay structure 300 and the first relay structure 100, thereby controlling the deep sea winding and unwinding cart 23.

I.e. communication between sea-to-air and then sea medium is achieved.

It should be noted that, when the underwater acoustic communication range of the water surface user is exceeded, the water surface user, which is the water surface user, also uses the radio or laser signal to perform communication, and all the water surface users, which use the radio or laser signal to perform communication, use the first relay structure 100 as a relay node to perform communication between the air and sea media.

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

The intercommunication between the first relay structure 100 and the third relay structure 300 is used for communication between the above-water user and the underwater user beyond the underwater acoustic communication range of the above-water user, which is a surface user, and for the above-water user (e.g., aerial platform, land platform, etc.) which communicates using radio or laser signals.

In the present application, since the first and third underwater acoustic communication modules 130 and 3112 communicate with each other and the first and second underwater acoustic communication modules 130 and 210 communicate with each other, the information storage unit a may be provided in the first relay structure 100 or the information access unit B may be provided in the second relay structure 200.

When the information access unit a is provided in the first relay configuration 100, the information access unit a is connected with the communication and data processing unit 120.

When the information access unit B is provided in the second relay configuration 200, the information access unit B is connected to the integrated control unit 220. In the present application, referring to fig. 2, information access section 3114 may be provided in third relay configuration 300, and information processing section 3113 may be connected to information storage section 3114.

The information access unit A/B/3114 is used for storing data (such as position, intelligence, instruction, etc.) from the user on water, and is used for calling the user in the water after the arrival, when the relay node is activated, and ensuring the underwater safety when the user extracts the information.

The underwater user can also store the related data of the underwater user in the information access unit A/B/3114, and the water surface user activates the relay node to call the needed information when the water surface user is in the underwater acoustic communication range.

When the underwater acoustic communication range of the water surface user is exceeded, the water surface user also communicates by using a radio or laser signal, and for the water surface user communicating by using the radio or laser signal, when the first relay structure 100 floats out to the top communication head to expose out of the water surface within a preset time period, the relay node is activated, and required information is retrieved and converted into the radio or laser signal to be sent back or uploaded.

The information access unit 3114 is provided in fig. 2 as an example.

When the underwater acoustic communication range of the water surface user is exceeded, the water surface user, which is the water surface user at this time, also performs communication by using a radio or laser signal, and for the water surface user performing communication by using the radio or laser signal, when the first relay structure 100 floats out to the top communication head exposed out of the water surface within a preset time period, the water surface user stores data in the information access unit 3114 through the first relay structure 100 and the third underwater acoustic communication module 3112.

When the user is late under water, the third relay structure 300 is activated, and the desired information is retrieved from the information access unit 3114.

When the underwater user extracts information and sends the information to the overwater user, if the overwater user is a water surface user and is in the underwater acoustic communication range, the underwater user is directly uploaded to the overwater user.

If the communication range exceeds the underwater acoustic communication range of the water surface user, which is the water surface user, also uses radio or laser signals for communication, and for the water user using radio or laser signals for communication, when the first relay structure 100 does not float to the position where the top end communication head is exposed, the information may be stored in the information access unit 3114, and after the first relay structure 100 floats to the position where the top end communication head is exposed, the marine information processing apparatus is activated to call the required information.

In this way, when the first relay structure 100 floats to the top end communication head, which is exposed to the water surface, and transmits information back to the user on the water, the underwater user is already away from the original location to ensure the safety of the underwater user, and then after the information is transmitted, the first relay structure 100 is also pulled back by the deep sea take-and-place reel 230 to be hidden to the preset floating depth under the water surface.

When the user arrives at the delayed underwater, the underwater user first needs to send an activation command to the information carrier 310 to activate the information carrier 310, and then can extract the information in the information access unit 3114.

When the communication and navigation of the aerial platform, the land platform, the aerial platform are limited, the first relay structure 100 replaces the function thereof by information conversion when the top communication head is floated out to the surface where the top communication head is exposed, and the communication mode is described as above, but not limited thereto.

When the third relay structure 300 is deployed underwater, the information carrier 310 is released from the anchor device 320 when it is sunk to a certain depth (which can be preset), and the anchor device 320 is sunk to the sea bottom, so as to anchor the relay node.

In order to achieve the above-described design between the information carrier 310 and the anchor device 320, reference is made to fig. 4 to 11.

In order to achieve that the information carrier 310 can be released from the anchor means 320, the information carrier 310 is designed as follows.

The information carrier 310 comprises, in addition to an information unit 311, a floating body 312, wherein the information unit 311 comprises a housing 3111.

As described 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 disposed in the housing 3111, wherein the third underwater acoustic communication module 3112 is exposed to water.

Referring to fig. 4 to 7, the housing 3111 is formed integrally with the third underwater acoustic communication module 3112, the information processing unit 3113, and the third power supply unit inside thereof, in a torpedo shape, and has a circular cross section.

The housing 3111 is fixed in the floating body 312, and the third underwater acoustic communication module 3112 disposed at the top end should protrude from the floating body 312 when the housing 3111 is fixed in the floating body 312.

The housing 3111 is secured within the float 312 in the following manner.

A through hole 313 is formed in the floating body 312 in the water depth direction, and the case 3111 is inserted into the through hole 313, and at this time, both the upper end and the lower end of the case 3111 extend out of the floating body 312.

A plurality of annular grooves (not shown) are formed in the inner side wall of the through hole 313 in the depth direction, the housing 3111 is fitted over the plurality of annular rings 314, and each annular ring 314 is disposed at a corresponding annular groove, so that the housing 3111 is restricted from moving up and down in the floating body 312, and the housing 3111 is prevented from falling out of the floating body 312, thereby fixing the housing 3111 in the floating body 312.

In order to satisfy the redundant design, two information units 311 and 311 'are arranged side by side in the floating body 312, the design of each information unit 311/311' being identical.

The cable of the underwater cable laying 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.

As described above, the information carrier 310 is disposed on the anchor device 320, and since the housing 3111 is fixed together with the internal devices (the third underwater acoustic communication module 3112, the information processing unit 3113, and the third power supply unit) and the floating body 312, the placement of the information carrier 310 on the anchor device 320, specifically, the placement of the floating body 312 in the anchor housing (not shown) of the anchor device 320 is achieved.

When the depth is not reached, the information carrier 310 is stabilized in the anchor housing because its own gravity is larger than its buoyancy, and when the information carrier 310 continues to sink until its buoyancy is larger than its own gravity, the information carrier 310 comes out of the anchor housing and floats.

Wherein the float 312 has a positive buoyancy in accordance with the first and

second relay structures

100 and 200, and the anchor device 320 has a negative buoyancy.

The anchor device 320 as described above can be referred to in prior patent application No. 202111254747.6, the anchor device (identified as anchor device a) entitled "an anchor device", the specific construction of which is incorporated herein by reference in its entirety.

The cable of the underwater cable laying 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 member of the anchor device 320 through the cable.

When the information carrier 310 sinks to a certain depth, the information carrier is separated from the anchor shell and floats when the buoyancy force borne by the information carrier is larger than the self gravity, and the suspension height of the information carrier is limited by the length of the cable.

The anchor device 320 can then perform the function of traction fixation as described in the prior art for anchor device a.

Alternatively, the anchor device 320 may be implemented in other configurations.

Alternatively, anchor rod 326 may be connected to anchor base 324 via a rotatable shaft 329 such that anchor rod 326 is rotatably connected between first fluke 325 and second fluke 325', i.e., rotatable shaft 329 has one end fixedly connected to a portion of anchor base 324 on the same side of first fluke 325 and second fluke 325' and the other end fixedly connected to a portion of anchor base 324 on the same side of first fluke 325 and second fluke 325'.

The anchor chain 327 is connected to the anchor rod 326 at one end and to the anchor housing at the other end, and the length of the anchor chain 327 can be designed as required.

A connector may be provided on the anchor housing for connecting an anchor chain 327.

In some embodiments of the present application, the anchor device 320 further includes a divider plate 3221 for dividing the cavity of the anchor housing into upper and lower first and second cavities (i.e., a lower cavity C2).

Referring to fig. 8, a 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.

Specifically, a connecting hole is formed on the lug 3225, and the other end of the anchor chain 327 is connected to the connecting hole by locking.

In some embodiments of the present application, referring to fig. 8-11, first fluke 325 and second fluke 325' lie flat on anchoring base plate 323, occupying less space, thereby reducing the space of the second cavity, contributing to a compact, compact design of the product.

Referring to fig. 5 and 10, first seal slide assembly 328 is sealingly mounted within first fluke 325, and free end 3284 extending beyond first fluke 325 extends into anchor housing first sidewall throughbore 3223, and specifically into second cavity first sidewall throughbore 3223.

Second seal-slide assembly 328 'is sealingly mounted within second fluke 325' and extends beyond free end 3284 'of second fluke 325' into second sidewall throughbore 3223 'of the anchor housing, and in particular into second sidewall throughbore 3223' of the second cavity.

First seal slide assembly 328 and second seal slide assembly 328' are each snap-fit to the anchor housing when anchor apparatus 320 is in the inoperative condition.

First and second seal slide assemblies 328, 328' are hydraulically disengaged from the anchor housing when anchor apparatus 320 is at a predetermined depth underwater.

In particular, the anchor housing is connected to a side wall of the anchor housing, in particular to a side wall of the second cavity, by means of a connecting assembly.

The connection assembly includes a first connector 3231, a second connector 3232, and an ear hook 3233.

The first connecting member 3231 is an L-shaped plate, and includes a first horizontal plate and a first vertical plate, the first horizontal plate is fixedly connected to the anchoring base plate 323, the first vertical plate is disposed between the free end 3284 of the first sealing sliding assembly 328, which extends beyond the first anchor 325, and the first sidewall through hole 3223 of the anchor housing, and the free end 3284 of the first sealing sliding assembly 328, which extends beyond the first anchor 325, extends into the first sidewall through hole 3223 of the anchor housing through the first through hole formed in the first vertical plate.

The second connecting member 3232 is an L-shaped plate, and includes a second horizontal plate and a second vertical plate, the second horizontal plate is fixedly connected to the anchoring base plate 323, the second vertical plate is disposed between the free end 3284 'of the second sliding seal assembly 328' extending beyond the second fluke 325 'and the second through hole 3223' of the second side wall of the anchor housing, and the free end 3284 'of the second sliding seal assembly 328' extending beyond the second fluke 325 'extends into the second through hole 3223' of the second side wall of the anchor housing through the second through hole formed in the second vertical plate.

Referring to fig. 8 to 10, in order to stably anchor the base plate 323, an ear hook 3233 is further provided, and the ear hook 3233, the first connector 3212, and the second connector 3232 form a triangular pattern.

The ear hook 3233 is attached at one end to the anchor base 323 and at a free end to a projection (not shown) on the inside wall of the anchor housing.

The manner in which the free end of the ear hook 3233 is hooked on the lug is such that the ear hook 3233 is easily separated from the lug when the first sealing slide 328 and the second sealing slide 328' are separated from the anchor housing under the influence of water pressure.

Specifically, the ear-hook 3233 can be disposed in a Z-shape, and includes a first horizontal portion, a vertical portion abutting against the first horizontal portion, and a second horizontal portion abutting against the vertical portion, wherein the extending directions of the first horizontal portion and the second horizontal portion are away from the vertical portion and extend back to back.

The first transverse portion is lapped over the bump and the second transverse portion is fixedly attached to the anchor floor 323.

The first seal slide assembly 328 and the second seal slide assembly 328' are identical in construction and, therefore, the construction of the first seal slide assembly 328 will be described as an example.

To assemble first seal slide subassembly 328 to first fluke 325, a retaining groove 3251 is formed corresponding to first fluke 325.

Referring to fig. 10, first seal slide assembly 328 includes a resilient member 3281 and a plunger 3282.

The elastic piece 3281 is positioned in the limiting groove 3251, and one end of the elastic piece abuts against the bottom wall of the limiting groove 3251; plunger 3282 is sealingly slidably disposed in retaining groove 3251 and extends beyond first fluke 325, i.e., a portion of plunger 3282 is disposed in retaining groove 3251, slides relative to retaining groove 3251 and seals retaining groove 3251 while sliding, and the other end of resilient member 3281 abuts against the end of plunger 3282 in retaining groove 3251.

In the present application, the resilient member 3281 is a spring, and in the non-operating state, it is used to provide a resilient force to the plunger 3282, so that it can clamp the anchor housing via the first connecting member 3231, and in the operating state, it can be compressed and deformed.

Alternatively, the elastic member 3281 is any deformable element that can provide an elastic restoring force, such as silicon rubber or the like.

Referring to fig. 10 and 11, the free end 3284 of the plunger 3282 extending beyond the first cat's claw 325 extends into the first through hole of the first vertical plate in the first connector 3231 and further into the first sidewall through hole 3223 of the anchor housing.

When the relay node is deployed underwater, as the depth increases, the hydraulic pressure acts on the free end 3284 of the plunger 3282 (see the direction indicated by the arrow on the right side in fig. 11) to move the plunger 3282 toward the elastic member 3281 and press the elastic member 3281 until the hydraulic pressure acts to move the plunger 3282 until the free end 3284 thereof is disengaged from the first sidewall through hole 3223 of the anchor housing.

Likewise, the same is true for second seal-slide assembly 328', and water pressure acts to move the plunger of second seal-slide assembly 328' to disengage its free end 3284 'from the anchor housing second sidewall throughbore 3223', as indicated by the left arrow in FIG. 11.

Since the other fulcrum of anchor floor 323 is connected to the anchor housing by ear hook 3233, anchor floor 323, along with anchor base 324, anchor bar 326, anchor chain 327, and pair of flukes 325/325 'are all submerged when plunger 3282 of first seal slide assembly 328 and the plunger of second seal slide assembly 328' are both disengaged from the anchor housing, see fig. 9.

During the continuous sinking process, the water pressure continues to act on the plunger 3282 of the first sealing sliding assembly 328, so that the plunger 3282 moves continuously toward the elastic member 3281 and presses the elastic member 3281 until the water pressure moves the plunger 3282 to disengage the free end 3284 thereof 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 slide assembly 328 'to continue its movement toward the elastomeric member and compress the elastomeric member until the hydraulic pressure acts to move the plunger to disengage its free end 3284' from the second through-bore of the second vertical plate in the second connector 3232.

At this time, the whole of anchor base 324, anchor bar 326, anchor chain 327, and pair of flukes 325/325 'is separated from anchor base plate 323, and the ground is grabbed and fixed by flukes 325/325'.

In order to seal the limiting groove 3251 and prevent water from entering the cavity where the elastic member 3281 is located, referring to fig. 11, at least one annular groove 3283 is formed on a portion of an outer side wall of the plunger 3282 extending into the limiting groove 3251, and a sealing ring (not shown) is installed in each annular groove 3283.

The sealing rings seal the gap between the plunger 3282 and the inner side wall of the limiting groove 3251, and meanwhile, the plunger 3282 can drive the sealing rings to slide in the limiting groove 3251, so that sliding sealing is realized.

Referring to fig. 4, 5 and 8, in some embodiments of the present application, the anchor housing includes a first housing 321 and a second housing 322 connected one above the other.

The first housing 321 forms a first accommodation space.

The second housing 322 has a partition plate 3221 therein, the partition plate 3221 divides the second housing into an upper cavity C1 and a lower cavity C2, the first accommodating space and the upper cavity C1 form the first cavity, and the lower cavity C2 is the second cavity.

An annular boss 3211 is formed on an inner sidewall of the first receiving space to hold the floating body 312; the connecting rails 3222 as described above may be disposed on the inner sidewalls of the upper chamber C1.

The first housing 321 and the second housing 322 are connected by a connecting portion, for example, a connecting flange.

That is, the lower end of the first casing 321 has a first interface portion 3212, the upper end of the second casing 322 has a second interface portion 3224, and the first interface portion 3212 and the second interface portion 3224 are fittingly connected.

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.

A set of first interface connecting holes 3213 is formed in the side wall of the first interface flange, a set of second interface connecting holes 3226 is formed in the side wall of the second interface flange, and the first interface connecting holes 3213 and the second interface connecting holes 3226 are correspondingly fixed by screws.

By designing the anchor housing as the first and

second housings

321, 322 as described above, it is possible to act as a counterweight to the anchor device 320 while making the anchor housing easier to assemble.
