[0021] Figure 1 Schematic diagram of the implementation environment architecture of the underwater transmission device provided in the embodiment of the present application. Figure 1 As shown, the implementation environment architecture may include an offshore platform 101 and an underwater electrical equipment 102 .

[0022] Exemplarily, the offshore platform 101 may be a large steel structure built at sea, which may be specifically classified into a fixed platform fixed on the seabed, a floating platform floating on the sea surface, or a semi-submersible platform.

[0023] Exemplarily, the underwater electrical equipment 102 may be various electrical equipment used in an underwater environment, which may be specifically divided into lighting equipment, electrical equipment, and power equipment, etc.

[0024] Exemplarily, the offshore platform 101 can provide power supply to the underwater electrical equipment 102 , and perform data interaction and transmission with the underwater electrical equipment 102 .

[0025] In a specific implementation, the offshore platform 101 can supply electricity to the underwater electrical equipment 102, so that the underwater electrical equipment 102 can collect underwater environmental data through sensors; the underwater electrical equipment 102 can transmit the data to the offshore platform 101 after collecting the underwater environmental data, so that the offshore platform 101 can preliminarily process and store the data; after acquiring the underwater environmental data, the offshore platform 101 can send control instructions corresponding to the analysis results to the underwater electrical equipment 102 based on the analysis results of the underwater environmental data, thereby changing the working state of the underwater electrical equipment 102.

[0026] Specifically, the offshore platform 101 can be stabilized by underwater fixed equipment, and the underwater transmission lines can be used to realize the power supply of the offshore platform 101 to the underwater electrical equipment 102 and the data transmission between the offshore platform 101 and the underwater electrical equipment 102.

[0027] At present, with the continuous development of communication technology, underwater power supply and communication devices play a key role in deep-sea energy exploration, seabed scientific research and other fields. In the existing technology, an underwater power supply and communication device can be formed by combining a shore-based power supply control system with an optoelectronic composite cable, an optoelectronic separator and an underwater power supply control system.

[0028] Specifically, the shore-based power supply control system can be used to convert AC power into DC power through a power converter, and continuously provide power supply and data transmission to underwater electrical equipment through optoelectronic composite cables to ensure the power supply stability and communication stability of the power supply control system. Among them, the optoelectronic separator can be used to separate the electrical signal and optical signal in the optoelectronic composite cable.

[0029] However, the above-mentioned shore-based power supply control system is usually fixed on the shore, which means that the electrical signal and optical signal separated by the photoelectric separator need to be transmitted from the shore to underwater. This type of long-distance signal transmission easily leads to power attenuation, decreased stability and increased costs of the shore-based power supply control system, making it difficult to achieve effective power supply and data transmission in deep sea or far from the shore. Based on this, a dynamic offshore platform can be used to combine a sea surface stabilization device, an optoelectronic composite cable, and a data acquisition and transmission circuit to form an underwater power supply and communication device.

[0030] Specifically, a dynamic offshore platform can be used to supply power to underwater electrical equipment through optoelectronic composite cables, and the data acquired by the underwater electrical equipment can be transmitted to the dynamic offshore platform through optoelectronic composite cables, so that the underwater power supply and communication devices can realize real-time data transmission while providing power supply. Among them, the sea surface stabilization device can be used to ensure the stability of the entire power supply system. The dynamic offshore platform can be, for example, the deck of a survey ship.

[0031] However, the stability and practicality of the sea surface stabilization device are easily affected by the extreme marine environment, which makes the above-mentioned dynamic offshore platforms unable to provide long-term stable power supply and communication services.

[0032] In order to solve the above problems, the above-mentioned sea surface stabilization device can be replaced by an anchor structure to achieve the stability of the dynamic offshore platform, but the cost of the existing anchor structure is positively correlated with the seabed depth. Specifically, the greater the seabed depth, the higher the cost of the anchor structure, and the high cost leads to certain limitations in the application of multi-anchor structures in deep-sea environments; in addition, when a single anchor structure is used in a deep-sea environment, the dynamic offshore platform will rotate or revolve around the anchor point due to the influence of the marine environment such as waves, which makes the underwater transmission line connecting the dynamic offshore platform and the underwater electrical equipment susceptible to torque or entanglement with the anchor chain, which in turn causes wear and tear of the underwater transmission line.

[0033] Therefore, the poor stability of the power supply and communication devices for underwater electrical equipment in the prior art has become a problem that needs to be solved.

[0034] Based on this, an embodiment of the present application provides an underwater transmission device, which can use fixed equipment to stabilize a mobile platform while avoiding wear and breakage of the transmission line through a stable link arranged corresponding to the first transmission line and a second transmission line which is specifically a stable composite line, thereby ensuring the power stability and communication stability of the underwater transmission device.

[0035] Figure 2 is a schematic diagram of the structure of an underwater transmission device provided in an embodiment of the present application, such as Figure 2 As shown, the underwater transmission device 20 can be composed of a mobile platform 201, an underwater transmission line 202, a fixed device 203 and an underwater power-consuming device 204, wherein the mobile platform 201 can be used to generate electric energy, the underwater power-consuming device 204 can be used to generate communication data, and the underwater transmission line 202 can be used to transmit electric energy and communication data.

[0036] Specifically, the underwater transmission line 202 may include a first transmission line 2021 and a second transmission line 2022, wherein one end of the first transmission line 2021 is connected to the mobile platform 201, the other end of the first transmission line 2021 is connected to one end of the second transmission line 2022 through a slip ring component 205, and the other end of the second transmission line 2022 is respectively connected to the underwater electrical equipment 204 and the fixed equipment 203 through a line switching device 206; at least one stable link 207 is also arranged between the slip ring component 205 and the mobile platform 201, and the stable link 207 is arranged corresponding to the first transmission line 2021, and is used to rotate around the slip ring component 205 when the mobile platform 201 moves; the second transmission line 2022 is a stable composite line of the transmission line and the stable link.

[0037] In a possible implementation, the mobile platform 201 may provide electric energy to the underwater power-consuming device 204 via the underwater transmission line 202 , and perform data transmission and interaction with the underwater power-consuming device 204 via the underwater transmission line 202 .

[0038] Exemplarily, the mobile platform 201 can be used to generate electrical energy, the underwater power-consuming equipment 204 can be used to generate communication data, and the underwater transmission line 202 can be used to transmit electrical energy and communication data.

[0039] Exemplarily, the mobile platform 201 may be an offshore platform disposed on the sea surface, wherein the mobile platform 201 may be a large steel structure built at sea, which may be specifically divided into a fixed platform fixed on the seabed, a floating platform floating on the sea surface, or a semi-submersible platform, etc.

[0040] Exemplarily, the underwater electrical equipment 204 may be various electrical equipment used in an underwater environment (eg, the seabed), and may be specifically divided into lighting equipment, electrical equipment, and power equipment, etc.

[0041] Specifically, Figure 3 2 is a flow chart of realizing data transmission between the mobile platform 201 and the underwater electrical equipment 204 provided in the embodiment of the present application, such as Figure 3 As shown, the data transmission process includes the following steps: In step 301 , the mobile platform 201 may supply electric power to the underwater power-consuming equipment 204 via the underwater transmission line 202 .

[0042] Step 302 , when the underwater power-consuming device 204 receives power from the mobile platform 201 , it can obtain underwater environmental data through sensors and transmit the obtained underwater environmental data to the mobile platform 201 .

[0043] In step 303, the mobile platform 201 may preliminarily process and store the underwater environment data, and obtain analysis results of the underwater environment data.

[0044] Specifically, after acquiring the underwater environmental data, the mobile platform 201 may send a control instruction corresponding to the analysis result to the underwater electrical equipment 204 based on the analysis result of the underwater environmental data, thereby changing the working state of the underwater electrical equipment 204 .

[0045] In a possible implementation, the underwater transmission line 202 may include a first transmission line 2021 and a second transmission line 2022 .

[0046] Exemplarily, the first transmission line 2021 and the second transmission line 2022 may be connected via a slip ring component 205 .

[0047] Specifically, one end of the first transmission line 2021 is connected to the mobile platform 201, and the other end of the first transmission line 2021 is connected to one end of the second transmission line 2022 through the slip ring component 205. The first transmission line 2021 can be connected to the power supply and communication interface of the mobile platform 201.

[0048] In a possible implementation, the material of the fixing device 203 may be steel, for example, a gravity anchor. Specifically, the gravity anchor may include a lifting ring, a tether ring, and an anchor body, wherein the lifting ring and the tether ring are formed by bending steel bars, and the anchor body is formed by integrally casting steel bars and concrete.

[0049] For example, when the fixed device 203 is a gravity anchor, the line between the fixed device 203 and the mobile platform 201 needs to have good stability while being able to transmit power and data, so as to ensure the stability of power transmission and data transmission while being able to stabilize the mobile platform 201 using the fixed device 203. Based on this, the underwater transmission line 202 can have at least one of stable transmission capability and stability.

[0050] Exemplarily, the first transmission line 2021 may be an optoelectronic composite cable that can simultaneously transmit optical signals and electrical signals. In order to prevent the first transmission line 2021 from being subjected to torque or entangled with the anchor chain and causing wear and breakage, at least one stabilizing link 207 may be provided at a corresponding position of the first transmission line 2021 (i.e., a corresponding position of the optoelectronic composite cable) to ensure the stability of the first transmission line 2021, wherein the stabilizing link 207 may be, for example, an anchor chain.

[0051] For example, two stable links 207 may be evenly arranged at corresponding positions of the first transmission line 2021 .

[0052] Specifically, the above-mentioned optoelectronic composite cable can be a composite cable that integrates two media, optical fiber and power conductor, into one, so as to realize data transmission while providing power supply.

[0053] Exemplarily, corresponding to the first transmission line 2021 , one end of the stable link 207 may be connected to the mobile platform 201 , and the other end may be connected to the slip ring component 205 .

[0054] Exemplarily, the end of the stable link 207 connected to the mobile platform 201 may be a fixed end, and the end connected to the slip ring component 205 may be a movable end.

[0055] Specifically, when the mobile platform 201 rotates or revolves around the fixed device 203, the rotation of the stabilizing link 207 at one end connected to the slip ring component 205 can offset the torsional force on the underwater transmission line 202 caused by the rotation of the mobile platform 201.

[0056] Exemplarily, line interfaces may be respectively provided on both sides of the slip ring component 205 . Specifically, one end may be used to connect to the first transmission line 2021 , and the other end may be used to connect to the second transmission line 2022 , so as to achieve conduction of the transmission lines through the slip ring component 205 .

[0057] Exemplarily, the second transmission line 2022 may be a composite line with stable transmission capability and stability, for example, an optoelectronic composite anchor cable made by integrating an optoelectronic composite cable and an anchor chain.

[0058] Specifically, the optoelectronic composite cable can be woven into the polyester cable anchor chain to form an optoelectronic composite anchor cable integrated with the cable.

[0059] In the embodiment of the present application, by connecting the end of the first transmission line 2021 away from the mobile platform 201 to the slip ring component 205 and setting at least one stable link 207 at the corresponding position of the first transmission line 2021, the slip ring component 205 can drive the movement of the stable link 207 when the mobile platform 201 moves (for example, rotates or revolves around the fixed device 203), so as to avoid the torsional force on the first transmission line 2021 when the mobile platform 201 moves, thereby avoiding the first transmission line 2021 from being damaged by force; secondly, by setting the second transmission line 2022 as an optoelectronic composite anchor cable made by integrating an optoelectronic composite cable and an anchor chain, the second transmission line 2022 can provide power supply and transmit data while realizing the function of an anchor chain, thereby avoiding the situation in which the anchor chain and the underwater transmission line in the anchoring structure are entangled with each other under the action of water flow, resulting in wear and breakage of the transmission line.

[0060] It should be noted that in order to reduce the manufacturing cost of the underwater transmission device 20, the setting length of the first transmission line 2021 can be shortened on the basis of utilizing the stable link 207 to avoid the first transmission line 2021 being subjected to stress, thereby shortening the length of the stable link 207 corresponding to the first transmission line 2021.

[0061] The underwater transmission device 20 provided in the embodiment of the present application can, on the one hand, utilize a fixing device 203 to connect to a mobile platform 201 so as to stabilize the mobile platform 201; on the other hand, divide an underwater transmission line 202 for transmitting electric energy and communication data into a first transmission line 2021 and a second transmission line 2022 connected by a slip ring component 205, so as to set a stable link 207 at a corresponding position of the first transmission line 2021 and set the second transmission line 2022 as a stable composite line, thereby reducing the torsional effect of the underwater transmission line 202 and avoiding entanglement between the underwater transmission line 202 and the stable link 207, thereby ensuring the power stability and communication stability of the underwater transmission device 20.

[0062] In another embodiment of the present application, other distributions of the underwater transmission line 202 in the underwater transmission device 20 are also provided. Exemplarily, the underwater transmission line 202 may also include a third transmission line 2023, which is arranged between the line switching device 206 and the underwater power-consuming device 204, and the third transmission line 2023 is a telescopic line provided with at least one floating block and at least one weight block.

[0063] In the embodiment of the present application, by setting the third transmission line 2023 connected to the underwater electrical equipment 204 as a telescopic line, when the mobile platform 201 moves irregularly around the fixed equipment 203, the third transmission line 2023 can be flexibly extended and contracted to avoid damage and breakage of the third transmission line 2023 under the action of tension.

[0064] In a possible implementation, the third transmission line 2023 may be provided between the line switching device 206 and the underwater power-consuming device 204 , so as to utilize the line switching device 206 to realize the connection among the mobile platform 201 , the fixed device 203 and the underwater power-consuming device 204 .

[0065] Exemplarily, the first end of the line switching device 206 can be used to connect to the second transmission line 2022 , the second end can be used to connect to the third transmission line 2023 , and the third end can be used to connect to the fixed device 203 .

[0066] Specifically, a stable link may be provided between the line switching device 206 and the fixing device 203. For example, when the fixing device 203 is a gravity anchor, the line switching device 206 may bear an anchoring force of tens to hundreds of tons, and the stable link connected to the third end of the line switching device 206 may be a ground chain, which may be a steel marine chain.

[0067] In the embodiment of the present application, based on the stable link set between the line switching device 206 and the fixing device 203, the anchoring force can be increased while limiting the lifting and lowering movement of the mobile platform 201.

[0068] Exemplarily, the third transmission line 2023 may be a telescopic line formed by alternately connecting floating blocks and heavy blocks.

[0069] For example, the third transmission line 2023 is provided with three floating blocks 401 and three weight blocks 402 , and the three floating blocks 401 and the three weight blocks 402 are alternately arranged.

[0070] Exemplarily, based on the floating blocks and the heavy blocks alternately arranged on the third transmission line 2023, the third transmission line 2023 may be in an “S” shape.

[0071] Specifically, when the mobile platform 201 moves, the degree of convergence of the third transmission line 2023 can be changed by changing the "S"-shaped internal curvature in the third transmission line 2023, thereby lengthening or shortening the vertical distance between the underwater electrical equipment 204 and the mobile platform 201 to avoid damage and breakage of the third transmission line 2023 under the action of direct pulling.

[0072] For example, Figure 2For example, when the mobile platform 201 moves to the right along the horizontal direction, the third transmission line 2023 can be stretched in the horizontal direction as the mobile platform 201 moves (i.e., the curvature inside the "S" shape in the third transmission line 2023 increases); when the mobile platform 201 moves to the left along the horizontal direction, the third transmission line 2023 can be contracted in the horizontal direction as the mobile platform 201 moves (i.e., the curvature inside the "S" shape in the third transmission line 2023 decreases).

[0073] It should be noted that the reason why floating blocks and weight blocks are alternately arranged on the third transmission line 2023 to form an "S" shape is because the combination of weight blocks and floating blocks can effectively avoid the mutual entanglement problem of the third transmission line 2023 under the influence of water flow, waves, etc., thereby ensuring the stability of the underwater transmission line to ensure the stability of power transmission and data transmission.

[0074] In another embodiment of the present application, another structural distribution of the underwater transmission device 20 is provided.

[0075] Exemplarily, the underwater transmission device 20 may include a mobile platform 201 disposed on the sea surface, wherein a power supply and communication interface is disposed at one end of the mobile platform 201 close to the seabed.

[0076] Specifically, the power supply and communication interface of the mobile platform 201 can be used to connect one end of the first transmission line 2021, and the other end of the first transmission line 2021 can be connected to the slip ring component 205. For example, the first transmission line 2021 can be an optoelectronic composite cable that can simultaneously transmit optical signals and electrical signals.

[0077] Correspondingly, at least one stable link 207 may be provided at a corresponding position of the first transmission line 2021 (ie, between the mobile platform 201 and the slip ring component 205 ) to ensure the stability of the first transmission line 2021 .

[0078] For example, the stable links 207 may be respectively arranged on both sides of the first transmission line 2021. The stable links 207 may be anchor chains, for example.

[0079] It should be noted that, since the mobile platform 201 is easily affected by the marine environment and generates irregular movements at sea (for example, rotation on its own or around a connection point), in order to avoid the torque generated by the irregular movement of the mobile platform 201, it is necessary to set at least one stable link 207 at the corresponding position of the first transmission line 2021 to prevent the first transmission line 2021 from being subjected to torque or entangled with the anchor chain, resulting in wear and breakage.

[0080] Exemplarily, the slip ring component 205 may have an interface connected to the end of the stable link 207 away from the mobile platform 201 , and line interfaces may be respectively provided on both sides of the slip ring component 205 .

[0081] Specifically, the end of the slip ring component 205 close to the mobile platform 201 can be used to connect the first transmission line 2021, and the end away from the mobile platform 201 can be used to connect the second transmission line 2022, so as to achieve conduction between the first transmission line 2021 and the second transmission line 2022 through the slip ring component 205.

[0082] Exemplarily, the second transmission line 2022 may be a composite line with stable transmission capability and stability, for example, an optoelectronic composite anchor cable made by integrating an optoelectronic composite cable and an anchor chain.

[0083] Specifically, the optoelectronic composite cable can be woven into the polyester cable anchor chain to form an optoelectronic composite anchor cable integrated with the cable.

[0084] In the embodiment of the present application, by configuring the second transmission line 2022 as an optoelectronic composite anchor cable that is made by integrating an optoelectronic composite cable and an anchor chain, the second transmission line 2022 can not only realize the function of an anchor chain but also have the ability to provide power supply and transmit data, thereby avoiding the situation in which the anchor chain and the underwater transmission line in the anchor structure are entangled with each other under the action of water flow, causing the transmission line to be worn and broken.

[0085] Exemplarily, one end of the second transmission line 2022 away from the mobile platform 201 may be connected to the line switching device 206. Specifically, the line switching device 206 may have three ports.

[0086] For example, the first end of the line switching device 206 can be used to connect to the end of the second transmission line 2022 away from the mobile platform 201 , the second end can be used to connect to the third transmission line 2023 , and the third end can be used to connect to the fixed device 203 .

[0087] Exemplarily, the material of the fixing device 203 may be steel, for example, a gravity anchor.

[0088] Specifically, the gravity anchor may include a lifting ring, a tether ring and an anchor body, wherein the lifting ring and the tether ring are formed by bending steel bars, and the anchor body is formed by integrally casting steel bars and concrete.

[0089] Exemplarily, a stable link 501 may be provided between the line switching device 206 and the fixing device 203. Based on this, when the fixing device 203 is a gravity anchor, the line switching device 206 can bear an anchoring force of tens to hundreds of tons, and the stable link 501 connected to the third end of the line switching device 206 may be a ground chain, which may be a steel offshore chain.

[0090] In the embodiment of the present application, based on the stable link set between the line switching device 206 and the fixing device 203, the anchoring force can be increased while limiting the lifting and lowering movement of the mobile platform 201.

[0091] Exemplarily, the third transmission line 2023 may be a telescopic line formed by alternately connecting floating blocks and heavy blocks, wherein the telescopic line may also be called a dynamic cable.

[0092] For example, the third transmission line 2023 may be provided with three floating blocks 401 and three heavy blocks 402, and the three floating blocks 401 and the three heavy blocks 402 are alternately arranged. Based on this, the third transmission line 2023 may be presented as follows Figure 2 "S" type shown.

[0093] Specifically, when the mobile platform 201 moves, the degree of convergence of the third transmission line 2023 can be changed by changing the "S"-shaped internal curvature in the third transmission line 2023, thereby lengthening or shortening the vertical distance between the underwater electrical equipment 204 and the mobile platform 201 to avoid damage and breakage of the third transmission line 2023 under the action of direct pulling.

[0094] For example, when the mobile platform 201 moves to the right along the horizontal direction, the third transmission line 2023 can be stretched in the horizontal direction as the mobile platform 201 moves (i.e., the curvature inside the "S" shape in the third transmission line 2023 increases); when the mobile platform 201 moves to the left along the horizontal direction, the third transmission line 2023 can be contracted in the horizontal direction as the mobile platform 201 moves (i.e., the curvature inside the "S" shape in the third transmission line 2023 decreases).

[0095] It should be noted that the reason why floating blocks and weight blocks are alternately arranged on the third transmission line 2023 to form an "S" shape is because the combination of weight blocks and floating blocks can effectively avoid the mutual entanglement problem of the third transmission line 2023 under the influence of water flow, waves, etc., thereby ensuring the stability of the underwater transmission line to ensure the stability of power transmission and data transmission.

[0096] Exemplarily, an underwater power-consuming device 204 may be provided at the other end of the third transmission line 2023 away from the line switching device 206 .

[0097] Specifically, the mobile platform 201 can supply power to the underwater power-consuming device 204 through the underwater transmission line 202. When the underwater power-consuming device 204 receives the power supply from the mobile platform 201, it can obtain underwater environmental data through sensors and transmit the obtained underwater environmental data to the mobile platform 201. After obtaining the underwater environmental data, the mobile platform 201 can preliminarily process and store the underwater environmental data, and obtain the analysis results of the underwater environmental data, so as to send control instructions corresponding to the analysis results to the underwater power-consuming device 204 based on the analysis results of the underwater environmental data, thereby changing the working state of the underwater power-consuming device 204.

[0098] The underwater transmission device 20 provided in the embodiment of the present application can, on the one hand, utilize a fixing device 203 to connect to a mobile platform 201 so as to stabilize the mobile platform 201; on the other hand, divide an underwater transmission line 202 for transmitting electric energy and communication data into a first transmission line 2021 and a second transmission line 2022 connected by a slip ring component 205, so as to set a stable link 207 at a corresponding position of the first transmission line 2021 and set the second transmission line 2022 as a stable composite line, thereby reducing the torsional effect of the underwater transmission line 202 and avoiding entanglement between the underwater transmission line 202 and the stable link 207, thereby ensuring the power stability and communication stability of the underwater transmission device 20.
