In order to realize communication between the cross-sea and air mediums, a transparent ocean is created, and the present application relates to a cross-sea and air medium communication relay node (hereinafter referred to as relay node) which includes a first relay structure 100, a second relay structure 200 and a third relay structure 300, see fig. 1 to 3.

When the relay node does not operate, 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 torpedo-shaped.

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 separating 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 separating device.

When the relay node is deployed under water and in an operating state, referring to fig. 2, the lower end of the first relay structure 100 is separated from the upper end of the second relay structure 200 by the first underwater separating device, and the lower end of the second relay structure 200 is separated from the upper end of the third relay structure 300 by the second underwater separating device, and a cable is shown by a dotted line in fig. 2.

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

The existing underwater separation device can adopt an underwater separation device (named as an underwater separation device A) disclosed in the patent application No. 20201314066. X and named as an underwater separation device.

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

The underwater separation device a is incorporated herein by reference in its entirety.

The existing underwater separation device may also employ an underwater separation device (denoted as an underwater separation device B) disclosed in patent application No. 202011310345.9 under the name of "underwater separation device".

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

The underwater separation device B is incorporated herein by reference in its entirety.

Of course, other underwater separation methods can be used for separating the two objects, and the separation method is not limited herein, so long as the separation of the two objects is realized.

The present application relates to water users, including surface users (e.g., vessels, surface unmanned vessels, buoys, etc.), aerial platforms (e.g., flying platforms (e.g., aircraft, drones, balloons, airships, etc.), aerial platforms (e.g., platforms applied through satellite nodes), or land-based platforms (e.g., liu Shangji land base stations, onshore control rooms, radio transceivers, etc.).

Many of the above-mentioned water users are equipped with the underwater acoustic communication device, and thus, communication can be directly performed within the underwater acoustic communication range of the water users having the underwater acoustic communication device (see the broken line portion of fig. 1), which is not described in detail in the present application.

When the underwater communication range of the water surface user is exceeded, the water surface user is also communicated by adopting a radio or laser signal, and the water surface user communicated by adopting the radio or laser signal can communicate by converting the radio or laser signal and the underwater sound signal when the first relay structure 100 floats to the top communication head to expose the water surface in a preset time period.

The application mainly relates to a relay node for realizing communication among cross-sea air media, in particular to bidirectional communication between radio signals or laser signals and underwater sound 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 sound communication module 130, and a first power supply unit (not shown), and the radio or laser signal communication transceiver 110, the first underwater sound 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 configured to supply power to the power consuming parts in the first relay structure 100, and may include a first battery and a first battery management unit configured to monitor and manage the first battery.

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

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.

The processed underwater sound information is sent to the first underwater sound communication module 130 through the communication and data processing unit 120.

After receiving the underwater acoustic information, the first underwater acoustic communication module 130 emits an underwater acoustic signal, thereby implementing conversion from a radio signal or a laser signal to the underwater acoustic signal.

The first underwater acoustic communication module 130 as described above is used to implement conversion between an underwater acoustic signal and an electric signal, and is designed, for example, by an underwater acoustic transducer and its peripheral circuits and the like.

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

The second relay structure 200 includes, in addition to a housing, a deep sea winding and unwinding vehicle 230, an integrated control unit 220, a second underwater sound communication module 210, an underwater rope laying control device 240, and a second power supply unit (not shown).

The second underwater acoustic communication module 210 as described above is also used to implement conversion between an underwater acoustic signal and an electric signal, for example, designed by an underwater acoustic transducer and its peripheral circuits and the like.

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

The second power supply unit is used to supply power to the power consuming 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 winding and unwinding vehicle 230 adopts a deep sea winding and unwinding vehicle disclosed in patent application number 202111255728.5 and named as a deep sea winding and unwinding vehicle, and the specific structure of the deep sea winding and unwinding vehicle 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 part of the integrated control unit 220.

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

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

The integrated control unit 220 processes the underwater sound information, outputs a signal to the deep sea winding and unwinding vehicle 230, or outputs to the underwater rope laying control device 240, that is, at this time, realizes air-to-sea medium communication.

Normally, the first relay structure 100 is hidden under water at a predetermined levitation depth, which may be controlled by a predetermined instruction of the integrated control unit 220.

The winding and unwinding time and the interval time of the cable control command of the deep sea winding and unwinding vehicle 230 can also be set by a preset program in the integrated control unit 220, so as to control the interval time and the time of the first relay structure 100 to be floated.

In order to change the floating interval time and the floating time of the first relay structure 100, it is necessary to change the floating interval time and the floating time by an external command when the first relay structure 100 floats up to the top communication head to be exposed to the water 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, the preset levitation depth will not be changed after being preset in the integrated control unit 220.

The first cable control command for releasing the cable is received from the integrated control unit 220 at the deep sea reel-up 230, and is used for releasing the radio or laser signal communication reel-up 110 of the first relay structure 100 to the water surface, thereby being used for receiving and transmitting radio or laser signals in the floating time range.

After the floating time range is exceeded, the deep sea winding and unwinding vehicle 230 receives a second cable control instruction from the integrated control unit 220 for recovering the cable, and the second cable control instruction is used for pulling the first relay structure 100 back to the preset suspension depth under the water surface, so that the first relay structure 100 is safely hidden and prevented from being damaged or found due to exposure to the water surface.

The first cable control command and the second cable control command as described above are both commands preset in the integrated control unit 220 or commands after the preset commands are modified by external commands in the present application.

In addition, a weapon, a jammer, a detector, or the like may be mounted on the top end of the first relay structure 100, and when the first relay structure 100 is released to the water surface, an opponent may be warned, hit, or disturbed, or the above functions may be provided at the same time.

Similarly, the integrated control unit 220 is connected to the underwater rope laying control device 240 (see the dashed line frame in fig. 1), and a preset depth control instruction for setting the second relay structure 200 to a preset levitation depth is also preset in the integrated control unit 220. The cable in the underwater cable deployment control device 240 is connected to the third relay structure 300.

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

The underwater rope laying control device 240 receives the issued 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 several tens meters to several hundreds meters residing under 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 thus, the second relay structure 200 can be used as a base point for the first relay structure 100 to descend (i.e., to float up to the top communication head to be exposed to the water surface) after being set to a depth (i.e., to pull back to the preset levitation depth below the water surface).

In some embodiments of the present application, the underwater cable deployment control device 240 employs the underwater cable deployment control device disclosed in patent application number 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 the dashed line part in fig. 1 and 2, when the underwater acoustic communication range of the water surface user is within, the underwater acoustic communication machine of the water surface user directly transmits an underwater acoustic signal to the underwater user.

When the underwater user exceeds the underwater sound communication range of the water user, the underwater user who is the water user also adopts radio or laser signals to communicate at the moment, and the underwater user who adopts radio or laser signals to communicate floats to the top end communication head of the first relay structure 100 to expose the water surface, information such as position or data (such as information and instructions) of the underwater user can be received and directly downloaded to the underwater user, so that the underwater user can use the underwater user immediately when the underwater user arrives immediately.

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

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

When the underwater acoustic communication range of the water surface user is within, the water surface user may also issue 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 vehicle 230.

In addition, the integrated control unit 220 is also capable of receiving relevant instant information about the second battery, such as a remaining power, an instant current voltage, etc., through the second battery management unit in the second power supply unit.

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

In this way, the conversion of the underwater acoustic signal into a radio or laser signal is achieved, i.e. the sea-to-air medium communication is achieved.

Likewise, the communication and data processing unit 120 can also receive relevant instant information about the first battery, such as the remaining power, the 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 information representing the instant messages is output, and when the first relay structure 100 floats up to the top communication head to expose out of the water surface, the control information is returned to the water surface by the radio or laser signal communication transceiver 110, so that the monitoring of the underwater first battery is realized.

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

The above-mentioned various information of the first battery and the second battery can be returned to the above-mentioned user through the radio or laser signal communication transceiver 110 when the first relay structure 100 floats to the top communication head to expose the water surface after receiving the issued instruction according to the requirement of the above-mentioned user, that is, the above-mentioned user can realize the on-demand return, so that the above-mentioned user can timely master the electric quantity condition in the processing device.

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

However, as the ocean depths vary, the ocean environments vary, and thus, in order to achieve reliable transmission of underwater acoustic signals, and 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 comprises an information carrier 310 and an anchor device 320, the information carrier 310 being arranged on the anchor device 320, and a cable in the underwater rope deployment control device 240 connecting the information carrier 310 and the anchor device 320 (see fig. 3), in particular the cable connecting the upper end of the information carrier 310, the lower end of the information carrier 310 being connected to the anchor device 320 by 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 as described above is for realizing conversion between an underwater acoustic signal and an electric signal, and is designed by an underwater acoustic transducer, a peripheral circuit thereof, and the like, for example.

The third power supply unit is configured to supply power to the power consuming parts in the third relay structure 300, and may include a third battery and a third battery management unit configured to monitor and manage the third battery.

The third underwater acoustic communication module 3112 is provided at an upper end of the information carrier 310, and receives information issued by the user on water through the first underwater acoustic communication module 130 in the first relay structure 100.

When the underwater communication range of the water surface user is exceeded, the water surface user is also communicated by adopting a radio or laser signal, and the water surface user communicated by adopting the radio or laser signal can communicate by converting the radio or laser signal and the underwater sound signal when the first relay structure 100 floats to the top communication head to expose the water surface.

Accordingly, when the third underwater acoustic communication module 3112 is provided, the third underwater acoustic communication module 3112 receives the underwater acoustic signal transferred through the first underwater acoustic communication module 130 in the first relay structure 100.

When the first relay structure 100 floats to the top communication head and is exposed to the water surface, the radio or laser signal communication transceiver 110 may receive information such as position or data (e.g. information, instructions, etc.) from the user on the water, and control the first underwater acoustic communication module 130 to output an underwater acoustic signal corresponding to the information after being processed by the communication and data processing unit 120, where the underwater acoustic signal is received by the third underwater acoustic communication module 130 and is output to the user under water, and the user under water is used immediately when coming immediately.

I.e. to enable communication of air-to-sea media.

The underwater user may upload the related data of the underwater user to the radio or laser signal communication transceiver 110 and then upload the data to the above-water user 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.

The underwater user may also sequentially send 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 of the second relay structure 200 through the third relay structure 300 and the first relay structure 100, so as to control the deep sea winding and unwinding vehicle 23.

Namely, the communication between the sea to the air and the sea medium is realized.

When the underwater acoustic communication range of the water surface user is exceeded, the water surface user is also communicated by using a radio or laser signal, and all the water surface users communicating by using the radio or laser signal communicate with each other by using the first relay structure 100 as a relay node.

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

The first relay structure 100 and the third relay structure 300 communicate with each other for communication between the above-water user and the underwater user when the above-water user's underwater acoustic communication range is exceeded and the above-water user (e.g., an aerial platform, an overhead platform, a land platform, etc.) communicating by radio or laser signals is used.

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

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

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

The information access unit a/B/3114 is used for storing data (e.g., location, intelligence, instructions, etc.) from the user on water, for delaying the incoming underwater user from invoking when the relay node is activated, and ensuring underwater security when the underwater user extracts information.

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

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

The information access unit 3114 is provided in fig. 2 for illustration.

When the underwater user exceeds the underwater acoustic communication range of the water surface user, the above-water user also uses radio or laser signals to communicate, and the above-water user can store data in the information access unit 3114 through the first relay structure 100 and the third underwater acoustic communication module 3112 when the first relay structure 100 is floated to the top communication head to expose the water surface within a preset period of time.

When the underwater user arrives with a delay, the third relay structure 300 is activated, and the required information is retrieved from the information access unit 3114.

When the underwater user extracts information and sends the information to the water user, if the water user is a water user and is in the underwater sound communication range, the underwater user directly uploads the information to the water user.

If the communication range of the underwater user exceeds the underwater sound communication range of the water surface user, the above-water user who is the water surface user also uses radio or laser signals to communicate at this time, when the first relay structure 100 does not float to the top communication head to expose the water surface, information can be stored in the information access unit 3114, and after the first relay structure 100 floats to the top communication head to expose the water surface, the marine information processing apparatus is activated to call the required information.

Thus, when the first relay structure 100 floats to the point that the top communication head is exposed to the water and returns information to the user on the water, the underwater user is also away from the original place, so as to ensure the safety of the underwater user, and after the information is sent, the first relay structure 100 is also pulled back to be hidden to the preset suspension depth below the water by the deep sea winding and unwinding vehicle 230.

Upon arrival of the lagging underwater user, the underwater user first needs to send an activation instruction to the information carrier 310 to activate the information carrier 310, after which the information in the information access unit 3114 can be extracted.

When, for example, the aerial platform, the land platform, the aerial platform communication, and the navigation are limited, the first relay structure 100 replaces its function by information conversion when it is floating to the top communication head and is exposed to the water, and the communication manner is as described above, which is not limited herein.

When the third relay structure 300 is deployed underwater, the information carrier 310 is released from the anchor device 320 when submerged to a depth (this depth can be preset), and the anchor device 320 is submerged to the sea floor to achieve relay node anchoring.

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 enable the information carrier 310 to be removed from the anchor device 320, the information carrier 310 is designed as follows.

The housing 3111 is fixed to the floating body 312, and the third underwater sound communication module 3112 provided at the top end should protrude from the floating body 312 when the housing 3111 is fixed to 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 a housing 3111 is inserted into the through hole 313, and at this time, both the upper end and the lower section of the housing 3111 extend out of the floating body 312.

To meet the redundancy design, two information units 311 and 311 'are juxtaposed within floating body 312, each information unit 311/311' being identical in design.

The cable in the underwater rope 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 by the cable.

As described above, the information carrier 310 is provided on the anchor device 320, and since the housing 3111 is fixedly provided together with the internal means (the third underwater sound communication module 3112, the information processing unit 3113 and the third power supply unit) and the floating body 312, it is achieved that the information carrier 310 is placed on the anchor device 320, in particular, the floating body 312 is placed in an anchor housing (not shown) of the anchor device 320.

When a certain depth is not reached, the information carrier 310 is stabilized in the anchor housing due to its own weight being greater than its buoyancy, and continues to sink until the information carrier 310 is subjected to a buoyancy greater than its own weight, from which the information carrier 310 is extracted and suspended.

Wherein the float 312 has a positive buoyancy in line with the first relay structure 100 and the second relay structure 200 and the anchor device 320 has a negative buoyancy.

The anchor device 320 as described above may be referred to as an anchor device (denoted as anchor device a) as disclosed in prior patent application number 202111254747.6, entitled "an anchor device", the specific structure of which is incorporated herein by reference in its entirety.

Referring to fig. 8, a lug 3225 is provided on a 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 connection hole is formed in the lug 3225, and the other end of the anchor chain 327 is connected to the connection 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 anchor bottom plate 323, taking up little space, thereby reducing the space of the second cavity, contributing to a miniaturized, compact design of the product.

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

The second connector 3232 is an L-shaped plate comprising a second horizontal plate and a second vertical plate, the second horizontal plate is fixedly connected to the anchor bottom plate 323, the second vertical plate is disposed between the free end 3284 'of the second seal slider assembly 328' extending beyond the second fluke 325 'and the second sidewall throughbore 3223' of the anchor housing, and the free end 3284 'of the second seal slider assembly 328' extending beyond the second fluke 325 'extends into the second sidewall throughbore 3223' of the anchor housing through a second throughbore formed in the second vertical plate.

Referring to fig. 8 to 10, in order to stabilize the anchor bottom 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 triangle pattern.

An ear hook 3233 is fixedly secured to the anchor bottom plate 323 and a free end is suspended from a projection (not shown) on the inside wall of the anchor housing.

The free ends of the ear hanger 3233 are hooked on the lugs in a manner that facilitates separation of the ear hanger 3233 from the lugs when the first and second seal slider assemblies 328, 328' are separated from the anchor housing by hydraulic pressure.

Specifically, the ear hook 3233 can be provided to be Z-shaped, including a first lateral portion, a vertical portion interfacing with the first lateral portion, and a second lateral portion interfacing with the vertical portion, wherein the extension directions of the first lateral portion and the second lateral portion are both away from the vertical portion to extend away from the back.

The first lateral portion is erected on the bump and the second lateral portion is fixedly attached to the anchor bottom plate 323.

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

To assemble first seal slide assembly 328 to first fluke 325, a limit groove 3251 is provided corresponding to first fluke 325.

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

The elastic member 3281 is disposed in the limit groove 3251, one end of the elastic member abuts against the bottom wall of the limit groove 3251, the plunger 3282 is disposed in the limit groove 3251 in a sealing sliding manner, and extends beyond the first fluke 325, i.e., a portion of the plunger 3282 is disposed in the limit groove 3251, slides relative to the limit groove 3251, seals the limit groove 3251 while sliding, and the other end of the elastic member 3281 abuts against one end of the plunger 3282 disposed in the limit groove 3251.

In the present application, the elastic member 3281 is a spring for providing an elastic force to the plunger 3282 to clamp the anchor housing through the first connection member 3231 in a non-operating state, and is capable of being compressively deformed in an operating state.

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

Referring to fig. 10 and 11, the free end 3284 of the plunger 3282, which extends beyond the first cat-foot 325, extends into the first throughbore of the first vertical plate in the first connector 3231 and further into the first sidewall throughbore 3223 of the anchor housing.

When the relay node is deployed under water, as the depth increases, the hydraulic pressure acts to the free end 3284 of the plunger 3282 (see the direction indicated by the right arrow in fig. 11) so that the plunger 3282 moves toward the elastic member 3281 side and presses 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 side wall through hole 3223 of the anchor housing.

Likewise, for the second seal slide assembly 328', the hydraulic action moves the plunger of the second seal slide assembly 328' such that its free end 3284 'disengages from the second sidewall throughbore 3223' of the anchor housing, see the direction indicated by the left arrow in FIG. 11.

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

During continued sinking, water pressure continues to act on the plunger 3282 of the first seal slide assembly 328, causing the plunger 3282 to continue moving toward the side of the resilient member 3281 and compressing the resilient member 3281 until the water pressure acts to move the plunger 3282 until its free end 3284 disengages from the first through-hole of the first vertical plate in the first connector 3231, and also acts on the plunger of the second seal slide assembly 328', causing the plunger to continue moving toward the side of the resilient member and compressing the resilient member until the water pressure acts to move the plunger until its free end 3284' disengages from the second through-hole of the second vertical plate in the second connector 3232.

At this point, the entirety of anchor foot 324, shank 326, chain 327 and pair of flukes 325/325 'is separated from anchor bottom plate 323, allowing for a ground engaging securement by flukes 325/325'.

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

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 up and down.

The first housing 321 forms a first accommodating space.

The second housing 322 has a partition plate 3221 therein, the partition plate 3221 dividing the second housing into an upper cavity C1 and a lower cavity C2, the first accommodating space and the upper cavity C1 forming the first cavity as described above, the lower cavity C2 being the second cavity as described above.

An annular boss 3211 is formed on an inner sidewall of the first receiving space for supporting the floating body 312, and a connecting rail 3222 as described above may be provided on an inner sidewall of the upper chamber C1.

The first casing 321 and the second casing 322 are connected by an interface portion, which is, for example, a connection flange.

That is, the first housing 321 has a first interface portion 3212 at a lower end thereof, and the second housing 322 has a second interface portion 3224 at an upper end thereof, and the first interface portion 3212 and the second interface portion 3224 are connected in an adapted manner.

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 connection holes 3213 are formed in the side wall of the first interface flange, a set of second interface connection holes 3226 are formed in the side wall of the second interface flange, and the first interface connection holes 3213 and the second interface connection holes 3226 are correspondingly connected and fixed through screws.

By designing the anchor housing as a first housing 321 and a second housing 322 as described above, it is possible to counterweight the anchor device 320 while making the anchor housing easier to assemble.
