Description

Technical Field

[0001] The present invention relates to the technical field of offshore new energy and fishery equipment. Specifically, it relates to a fixed wind-fishery integration platform with automatically convective cages. Background Art

[0002] With the decline of fishery resources, the marine fishery has shifted from the fishing industry to the aquaculture industry. The aquaculture area has also expanded from land to the sea and from inshore bays to deep water and the far sea. One of the main influencing factors is:

[0003] Currently, offshore wind turbine power generation equipment is mainly distributed in inshore waters, resulting in a certain degree of contradiction between the offshore wind energy development industry and aquaculture and fishery for a long time.

[0004] Moreover, the current fishery cages on the market have obvious disadvantages: due to the poor anti-wave ability of a single fishery cage device, once attacked by a typhoon, it will cause heavy losses; and because medium and large cages are often densely arranged in inshore waters, with small ocean currents and crowded spaces, fishery waste is easily accumulated, resulting in the deterioration of the water quality and bottom sediment of the breeding sea area, leading to problems such as slow growth and epidemic diseases of farmed fish. In order to keep the water environment in large cages suitable for aquaculture, it is often necessary to add some devices for creating currents and waves. Once such active environmental maintenance devices are added, a series of additional devices such as pumps and power supplies need to be added. First, the use cost is greatly increased, and second, it is difficult to meet the actual needs of the aquaculture industry's expansion to the far sea. Obviously, these auxiliary and power devices are difficult to work continuously and effectively in the far sea.

[0005] In summary, the existing aquaculture cage equipment has design defects, resulting in the technical problem of being difficult to meet the actual aquaculture needs. Summary of the Invention

[0006] The technical problem to be solved by the present invention is that the existing aquaculture cage equipment has design defects, resulting in the technical problem of being difficult to meet the actual aquaculture needs.

[0007] To solve the above problems, the present invention provides a fixed wind-fishery integration platform with automatically convective cages, including:

[0008] A support platform device, including a cylindrical platform frame, a vertically penetrating support column is connected in the central axis area of the platform frame, and the base of the support column is used to connect the platform positioning mechanism; a wind turbine generator set device, including a wind turbine generator set and an electrical assembly component, the bottom end of the wind turbine generator set is connected to the top end of the support column; a breeding cage group, including a plurality of breeding cages installed in the platform frame, and the breeding cages are evenly distributed in a circular shape around the support column;

[0009] On opposite sides of the outer edge of the aquaculture cage group, there are side floating boxes located within the platform frame. The side floating boxes shield the sides of the aquaculture cages. On the outer side of the platform frame, between the side floating boxes on both sides, there is a side window structure that communicates with the space where the aquaculture cage group is located, allowing ocean currents to pass through the aquaculture cages to form circulating water. On both sides of the side window structure, there is a deflector assembly protruding outside the platform frame, which is used to guide the ocean current to flow through the side window structures on both sides and pass through the internal aquaculture cage group. The deflector assembly is powered by a wind turbine generator to drive expansion and contraction to adapt to different ocean current conditions for ocean current guidance.

[0010] The present invention provides a novel design of a wind-fishing integrated platform, which combines wind power generation and marine aquaculture functions on an offshore operation platform. Inside the support platform device, a plurality of aquaculture cages distributed in a circular pattern are evenly supported by a platform frame. The wind turbine generator is connected to a support column at the center of the support platform device, and each aquaculture cage is evenly distributed on the outer periphery of the wind turbine generator to ensure the overall balance of the platform. To solve the problem of water circulation renewal in the aquaculture cages and make full use of surges and ocean currents, two relatively positioned side window structures are arranged inside the cylindrical platform frame, enabling ocean currents to pass straight through the internal aquaculture cages to achieve water body circulation renewal in the cages. To ensure that the platform frame maintains a stable angle under the action of ocean currents and allows ocean currents to continuously flow through the internal cages, a deflector assembly is arranged on both sides of the side window structure to guide the continuous passage of ocean currents. And by protruding the deflector assembly from the surface of the cylindrical frame, the torque of the platform device is greatly increased, enabling the platform device to remain stable in continuous ocean currents instead of rotating continuously. The deflector assembly can adaptively adjust the length of the platform frame extending out according to the ocean current velocity, enabling the platform to adapt to various ocean current velocities and ensuring continuous water flow supply to the internal aquaculture cages. The deflector assembly is powered by a wind turbine generator to drive expansion and contraction actions, solving the energy power consumption problem of the aquaculture cages, eliminating the need to rely on onshore power transmission for control and drive inside the cages, greatly enhancing the adaptability of the aquaculture cages to the water area, and effectively solving the technical problem that the existing aquaculture cage equipment has design defects and is difficult to meet the actual aquaculture requirements.

[0011] As a preferred solution, the deflector assembly includes deflector wing plates and a telescopic control mechanism for driving the deflector wing plates to extend the length of the platform frame. The deflector wing plates on both sides of the side window structure are parallel to each other, and the deflector wing plates at the outer edges of the two side window structures together enclose a linear flow path.

[0012] This design optimizes the structural design of the deflector assembly, which mainly includes two parts: the deflector wing plates and the telescopic control mechanism. When the deflector wing plates extend, two groups of deflector wing plates located on both sides of the two side window structures jointly enclose a linear water flow passage, and this water flow passage passes through the internal aquaculture cages. Further, to optimize the water circulation effect, four square aquaculture cages can be arranged in a square array, and there is a cross-shaped interval space between the four aquaculture cages. The water flow passage enclosed by the deflector wing plates exactly coincides with this interval space, ensuring the water circulation effect on both side cages simultaneously.

[0013] As a preferred solution, a slot structure for slidably accommodating the deflector wing plates is provided inside the platform frame. The telescopic control mechanism includes a telescopic drive motor and a rack and link. The rack and link is connected to the deflector wing plate, and the output shaft of the telescopic drive motor meshes with the rack and link through a transmission gear. By driving the output rotation of the telescopic drive motor, the rack and link is driven to linearly feed, thereby driving the deflector wing plate to extend or retract from the slot structure.

[0014] This design optimizes the structural design of the telescopic control mechanism. The rotation output by the drive motor is used as the driving power. A slot structure parallel to the side of the aquaculture cage is provided inside the platform frame. The deflector wing plate is a flat plate structure and can be telescopically accommodated in the slot structure. By driving the output rotation of the drive motor, the rotation is transmitted to the rack and link through a gear, thereby converting the rotational motion into a linear motion, and then driving the link to pull the deflector wing plate to perform linear feeding. There can be various different cooperation methods between the rack and link and the deflector wing plate. The two can be fixedly connected or rotatably connected such as hinged. The driving method of this deflector wing plate has a simple structure and stable control actions.

[0015] As a preferred solution, auxiliary flow stabilizer plates are provided on one side of each of the two side floating boxes of the platform frame. The outer surface of the auxiliary flow stabilizer plate is arc-shaped, one end is hinged to the platform frame, and the auxiliary flow stabilizer plate is also connected to a hydraulic drive mechanism for driving the auxiliary flow stabilizer plate to rotate and open and close. The auxiliary flow stabilizer plate forms a part of the outer contour of the cylindrical platform frame in the closed state.

[0016] Based on the structure of the above-mentioned deflector wing plates, this design further provides auxiliary flow stabilizer plates. The outer surface of the auxiliary flow stabilizer plate is arc-shaped, and one end is hinged. In the closed state, it forms a part of the outer edge contour of the cylindrical platform frame, ensuring that the cylindrical outer edge contour of the platform frame is not damaged in the closed state of the auxiliary flow stabilizer plate and making its hydrodynamic performance meet the requirements. By driving the opening and closing actions of the auxiliary flow stabilizer plate through the hydraulic drive mechanism, its main functions are as follows:

[0017] Due to the complex offshore sea conditions and turbulent ocean currents, the platform posture that has been debugged for the current ocean current conditions will be disturbed, generating a deflection torque, causing the support platform device to pitch forward. For this reason, an auxiliary flow stabilizer is designed at the side pontoon position. When a small disturbance occurs, the hydraulic drive mechanism pushes the auxiliary flow stabilizer to open at a small angle. Since the auxiliary flow stabilizer also has a certain airfoil, it will generate a rotational torque under the action of the ocean current, thereby ensuring continuous convection inside the support platform device.

[0018] As a preferred solution, the auxiliary flow stabilizer and the adjacent side pontoon are located symmetrically about the central axis of the platform frame; the auxiliary flow stabilizers located on the outer sides of the side pontoons at both ends of the platform frame are centrally symmetrical to generate a rotational torque in an open state to stably support the posture of the platform device in the ocean current.

[0019] The design optimizes the position distribution design between the auxiliary stabilizers and the side buoys, which are symmetrically distributed on both sides of the central axis of the platform device with the side buoys. By optimizing the opening and closing angles and positions of the auxiliary stabilizers located at the opposite ends of the platform, the auxiliary stabilizers at both ends are distributed symmetrically around the center. This structure helps the platform to generate continuous rotational torque under the action of ocean currents to offset turbulence and keep the platform's posture stable. This structure can achieve automatic internal convection when the ocean current deviates at a small angle.

[0020] As a preferred solution, a spoiler is provided between the side pontoon and the adjacent auxiliary stabilizer plate. The outer side surface of the spoiler is in the shape of an arc surface, one end of which is hinged to the platform frame and is also connected to the hydraulic drive mechanism for driving the opening and closing of the spoiler. In a closed state, the spoiler blocks the sea flow path perpendicular to the flow channel between the side window structures and constitutes a part of the outer contour of the cylindrical platform frame. In an open state, the spoiler allows the sea flow path perpendicular to the flow channel direction between the side window structures to pass through, thereby enhancing the water circulation of the aquaculture cage.

[0021] The design further adapts the fluid mechanics of the platform device as a whole to set up a spoiler. Since the aquaculture cages in the platform device also have a current passage in the direction perpendicular to the flow channel between the side window structures, the spoiler will conduct the current passage when it is open, and will close the current passage when it is closed. Such a structure can change the direction of the current passage in the platform device. When the spoiler is closed, the current cannot flow between the side pontoon and the auxiliary stabilizer. At this time, the auxiliary stabilizer located on one side of the side pontoon is opened at a small angle to guide the lateral current to flow to the guide wing, thereby improving the overall flow field characteristics of the platform.

[0022] As a preferred solution, a plurality of flow sensors are evenly distributed along the circumference of the outer edge of the platform frame, which are used to detect the ocean current conditions around the support platform device, so as to correspondingly control the opening and closing actions of the guiding wing plates, auxiliary flow stabilizing plates and flow blocking plates according to the ocean current conditions, and optimize the water flow circulation in the internal aquaculture cage.

[0023] This design optimizes the adaptability of the platform device to ocean current conditions. A plurality of flow sensors are evenly distributed on the outer edge of the platform frame. Preferably, 8 or more sensors are used to monitor the ocean current conditions in all directions in real time, and the opening and closing actions of the guiding wing plates, auxiliary flow stabilizing plates and flow blocking plates are adaptively controlled according to the direction and flow of the real-time ocean current, so as to adjust the attitude angle and water flow path of the platform device, and improve the water body circulation in the aquaculture cage inside the platform device.

[0024] As a preferred solution, hydraulic lifting columns are arranged at the side edge positions of each aquaculture cage on the platform frame. The aquaculture cage is hydraulically supported and cooperated with the hydraulic lifting column through a hydraulic cylinder sleeve. A hydraulic pump is arranged at the top of each aquaculture cage, and the hydraulic pump is drivingly connected to the hydraulic cylinder sleeve of the aquaculture cage, and is used to control the lifting and adjustment of the aquaculture cage along the hydraulic lifting column through hydraulic drive to adapt to different water level conditions.

[0025] This design optimizes the connection design of each aquaculture cage in the platform frame. The platform frame includes a plurality of vertically arranged hydraulic lifting columns. The aquaculture cage is hydraulically connected with the hydraulic lifting column through a hydraulic cylinder sleeve, and the hydraulic driving force is output through a hydraulic pump, so as to adaptively control the height of each aquaculture cage in the platform frame. One is to be able to adapt to different platform self-weights and draft conditions, and the other is to facilitate fishery operations through the design of conveniently adjusting the height of the aquaculture cage.

[0026] As a preferred solution, the electrical assembly component includes a power conversion and energy storage module, which is electrically connected to the hydraulic pump and is used to supply the power energy for the hydraulic pump. The power conversion and energy storage module is electrically connected to the telescopic drive motor and the hydraulic drive mechanism and is used to supply power to the telescopic drive motor and the hydraulic drive mechanism.

[0027] This design optimizes the electrical design of the platform. The electrical energy generated by the fan assembly is stored through the power conversion and energy storage module and supplied to the working requirements of the hydraulic pump, telescopic drive motor and hydraulic drive mechanism when needed. Through such a design, the working power supply of the platform device is completely self-sufficient; preferably, a central control module is set up to collect the flow data transmitted by the flow sensors and adaptively control the work of the telescopic drive motor and the hydraulic drive mechanism according to the flow data analysis.

[0038] Reference Figures 1-5 The following embodiments are described as follows. Figure 1 FIG. is a schematic diagram of the overall structure of a fixed wind-fishing integration platform with automatically convective net cages provided by the present invention; Figure 2 Is Figure 1 A schematic diagram of the support platform device of the fixed wind-fishing integration platform in ; Figure 3 Is Figure 2 A schematic top view structure diagram of the support platform device in ; Figure 4 Is Figure 2 A schematic diagram of the structure near the flow blocking plate on one side of the support platform device in ; Figure 5 Is Figure 2 A schematic diagram of the structure of the aquaculture net cage in the support platform device in.

[0039] The fixed wind-fishing integration platform with automatically convective net cages provided in this embodiment includes: a support platform device, including a cylindrical platform frame 2, a vertically penetrating support column 1 is connected in the central axis area of the platform frame 2, and the base of the support column 1 is used to connect the platform positioning mechanism; a wind turbine unit device, including a wind turbine unit 14 and an electrical assembly component, the bottom end of the wind turbine unit 14 is connected to the top end of the support column 1; an aquaculture net cage group, including a plurality of aquaculture net cages 3 installed in the platform frame 2, and the aquaculture net cages 3 are evenly distributed in a circular shape around the support column 1.

[0040] On opposite sides of the outer edge of the aquaculture net cage group, there are side floating boxes 15. The side floating boxes 15 are located inside the platform frame 2. The side floating boxes 15 block the sides of the aquaculture net cages 3. On the outer side of the platform frame 2, between the two side floating boxes 15 on both sides, there is a side window structure 4 communicating with the space where the aquaculture net cage group is located, which is used for the sea current to pass through the aquaculture net cages 3 to form circulating water. On both sides of the side window structure 4, there are deflector components protruding outside the platform frame 2, which are used to guide the sea current to flow through the side window structures 4 on both sides and pass through the internal aquaculture net cage group. The deflector components are powered by the wind turbine unit 14 to drive expansion and contraction to adapt to different sea current conditions for sea current guidance.

[0041] This embodiment provides a design for a new type of wind-fishing integration platform, which combines the functions of wind power generation and mariculture on an offshore operation platform. Inside the support platform device, a plurality of aquaculture cages 3 distributed in a circular pattern are evenly supported by the platform frame 2. The wind turbine 14 is connected to the support column 1 at the center of the support platform device, and each aquaculture cage 3 is evenly distributed on the outer periphery of the wind turbine 14 to ensure the overall balance of the platform. To solve the problem of water circulation renewal in the aquaculture cage 3 and make full use of the surging ocean currents, two side window structures 4 opposite to each other are arranged inside the cylindrical platform frame 2, allowing the ocean current to pass straight through the internal aquaculture cage 3 to realize the water body circulation renewal in the cage. To ensure that the platform frame 2 maintains a stable angle under the action of the ocean current and allows the ocean current to continuously flow through the internal cage, a deflector assembly is arranged on both sides of the side window structure 4 to guide the continuous passage of the ocean current. And by protruding the deflector assembly from the surface of the cylindrical frame, the torque of the platform device is greatly increased, enabling the platform device to remain stable in the continuous ocean current instead of rotating continuously. The deflector assembly can adaptively adjust the length of the platform frame 2 extended out according to the ocean current velocity, enabling the platform to adapt to various ocean current velocities and ensuring the continuous supply of water flow to the internal aquaculture cage 3. The deflector assembly is driven by the wind turbine 14 to perform telescopic actions, solving the energy consumption problem of the aquaculture cage 3, so that the cage does not need to rely on the power supply from the shore for control and drive, greatly improving the adaptability of the aquaculture cage 3 to the water area and effectively solving the technical problem that the existing aquaculture cage equipment has design defects and is difficult to meet the actual aquaculture requirements.

[0042] In the technical solution provided by this embodiment, the deflector assembly includes deflector vanes 5 and a telescopic control mechanism 6 for driving the deflector vanes 5 to extend the length of the platform frame 2. The deflector vanes 5 located on both sides of the side window structure 4 are parallel to each other, and the deflector vanes 5 at the outer edges of the two side window structures 4 together enclose a linear flow path.

[0043] This design optimizes the structural design of the deflector assembly, mainly including two parts: deflector vanes 5 and a telescopic control mechanism 6. When the deflector vanes 5 extend, the two groups of deflector vanes 5 located on both sides of the two side window structures 4 together enclose a linear water flow path, and this water flow path passes through the internal aquaculture cage 3. Further, to optimize the water circulation effect, four square aquaculture cages 3 can be arranged in a square array, and there is a cross-shaped interval space between the four aquaculture cages 3. The water flow path enclosed by the deflector vanes 5 exactly coincides with this interval space, ensuring the water circulation effect on both sides of the cages at the same time.

[0044] In the technical solution provided in this embodiment, a slot structure for slidably accommodating the diversion wing plate 5 is arranged inside the platform frame 2. The telescopic control mechanism 6 includes a telescopic drive motor and a rack connecting rod. The rack connecting rod is connected to the diversion wing plate 5. The output shaft of the telescopic drive motor is engaged with the rack connecting rod through a transmission gear. The rotation action output by the telescopic drive motor drives the rack connecting rod to perform linear feeding, so as to drive the diversion wing plate 5 to extend or retract from the slot structure.

[0045] This design optimizes the structural design of the telescopic control mechanism 6. The rotation output by the drive motor is used as the driving power. A slot structure parallel to the side of the aquaculture cage 3 is arranged inside the platform frame 2. The diversion wing plate 5 is a flat plate structure and can be telescopically accommodated in the slot structure. By outputting rotation by the drive motor and transmitting the rotation to the rack connecting rod through a gear, the rotational motion is converted into a linear motion, thereby driving the connecting rod to pull the diversion wing plate 5 to perform linear feeding. There can be various different matching methods between the rack connecting rod and the diversion wing plate 5. The two can be fixedly connected or rotatably connected such as hinged. The driving mode of the diversion wing plate 5 has a simple structure and stable control actions.

[0046] In the technical solution provided in this embodiment, auxiliary flow stabilizing plates 8 are arranged on one side of the two side floating boxes 15 of the platform frame 2. The outer surface of the auxiliary flow stabilizing plate 8 is in an arc shape. One end is hinged to the platform frame 2. The auxiliary flow stabilizing plate 8 is also connected with a hydraulic drive mechanism 7 for driving the auxiliary flow stabilizing plate 8 to rotate and open and close. The auxiliary flow stabilizing plate 8 forms a part of the outer contour of the cylindrical platform frame 2 in the closed state.

[0047] This design further arranges the auxiliary flow stabilizing plate 8 on the basis of the structure of the above-mentioned diversion wing plate 5. The outer surface of the auxiliary flow stabilizing plate 8 is in an arc shape, and one end is hinged. In the closed state, it forms a part of the outer edge contour of the cylindrical platform frame 2, ensuring that the cylindrical outer edge contour of the platform frame 2 is not damaged in the closed state of the auxiliary flow stabilizing plate 8 and making its hydrodynamic performance meet the requirements. The opening and closing actions of the auxiliary flow stabilizing plate 8 are driven by the hydraulic drive mechanism 7. Its main functions are:

[0048] Since the offshore sea conditions are relatively complex and the ocean currents are disordered, it will disturb the attitude of the platform that has been adjusted for the current ocean current situation, generate a deflection moment, and cause the support platform device to perform yaw motion. Therefore, the auxiliary flow stabilizing plate 8 is designed at the position of the side floating box 15. When a small disturbance occurs, the hydraulic drive mechanism 7 pushes the auxiliary flow stabilizing plate 8 to open at a small angle. Since the auxiliary flow stabilizing plate also has a certain airfoil shape, a turning moment will be generated under the action of the ocean current, so as to ensure the continuous convection inside the support platform device.

[0049] In the technical solution provided in this embodiment, the positions of the auxiliary flow stabilizers 8 and the adjacent side pontoons 15 are symmetrical about the central axis of the platform frame 2; the auxiliary flow stabilizers 8 located on the outer sides of the side pontoons 15 at both ends of the platform frame 2 are centrally symmetrical to generate a rotational torque in the open state to stably support the posture of the platform device in the ocean current.

[0050] This design optimizes the position distribution design between the auxiliary stabilizer 8 and the side buoyancy box 15, which is symmetrically distributed on both sides of the central axis of the platform device with the side buoyancy box. By optimizing the opening and closing angles and positions of the auxiliary stabilizer 8 located at the opposite ends of the platform, the auxiliary stabilizer 8 at both ends are distributed symmetrically around the center. Such a structure helps the platform to generate a continuous rotational torque under the action of ocean currents to offset turbulence and keep the platform's posture stable. Through this structure, automatic internal convection can be achieved when the ocean current deviates at a small angle.

[0051] In the technical solution provided in this embodiment, a spoiler 9 is arranged between the side pontoon 15 and the auxiliary flow stabilizer 8 adjacent thereto. The outer side surface of the spoiler 9 is in the shape of an arc surface, one end of which is hinged to the platform frame 2, and is also connected to a hydraulic drive mechanism 7 for driving the opening and closing of the spoiler 9. In the closed state, the spoiler 9 closes the sea flow path perpendicular to the flow channel between the side window structures 4 and constitutes a part of the outer contour of the cylindrical platform frame 2. In the open state, the spoiler 9 allows the sea flow path perpendicular to the flow channel direction between the side window structures 4 to pass through, thereby enhancing the water circulation of the aquaculture cage 3.

[0052] The design further adapts the fluid mechanics of the platform device as a whole to set the spoiler 9. Since the aquaculture cages 3 in the platform device also have a current passage in the direction perpendicular to the flow channel between the side window structures 4, the spoiler 9 will conduct the current passage when it is open, and will close the current passage when it is closed. Such a structure can change the direction of the current passage in the platform device. When the spoiler 9 is closed, the current cannot flow between the side pontoon 15 and the auxiliary stabilizer 8. At this time, the auxiliary stabilizer 8 located on one side of the side pontoon 15 is opened at a small angle to guide the lateral current to flow to the guide wing 5, thereby improving the overall flow field characteristics of the platform.

[0053] In the technical solution provided in this embodiment, a plurality of flow sensors 10 are evenly distributed along the circumference of the outer edge of the platform frame 2, which are used to detect the ocean current conditions around the supporting platform device, so as to control the opening and closing actions of the guide wing plate 5, the auxiliary flow stabilizing plate 8 and the spoiler 9 according to the ocean current conditions, thereby optimizing the water circulation conditions of the internal aquaculture cage 3.

[0054] This design optimizes the adaptability of the platform device to ocean current conditions. A plurality of flow sensors 10 are evenly distributed on the outer edge of the platform frame 2, preferably using 8 or more sensors, so as to monitor the ocean current conditions in all directions in real time, and adaptively control the opening and closing actions of the diversion wing plates 5, auxiliary flow stabilizing plates 8 and flow blocking plates 9 according to the direction and flow of the real-time sea current, so as to adjust the attitude angle of the platform device and the water flow passage, and improve the water body circulation of the aquaculture cages 3 in the platform device.

[0055] In the technical solution provided in this embodiment, hydraulic lifting columns 11 are provided at the side edge positions of each aquaculture cage 3 of the platform frame 2. The aquaculture cages 3 are hydraulically supported and cooperated with the hydraulic lifting columns 11 through hydraulic cylinder sleeves 13. Hydraulic pump machines 12 are provided at the tops of the aquaculture cages 3. The hydraulic pump machines 12 are drivingly connected to the hydraulic cylinder sleeves 13 of the aquaculture cages 3, and are used to control the lifting and adjustment of the aquaculture cages 3 along the hydraulic lifting columns 11 through hydraulic drive to adapt to different water level conditions.

[0056] This design optimizes the connection design of each aquaculture cage 3 in the platform frame 2. The platform frame 2 includes a plurality of vertically arranged hydraulic lifting columns 11. The aquaculture cages 3 are hydraulically connected and cooperated with the hydraulic lifting columns 11 through hydraulic cylinder sleeves 13, and output hydraulic driving force through the hydraulic pump machines 12, so as to adaptively control the height of each aquaculture cage 3 in the platform frame 2. One is to be able to adapt to different platform self-weights and its own draft conditions, and the other is to facilitate fishery operations through the design of conveniently adjusting the height of the aquaculture cages 3.

[0057] In the technical solution provided in this embodiment, the electrical assembly component includes a power conversion and energy storage module. The power conversion and energy storage module is electrically connected to the hydraulic pump machine 12 and is used to supply the power energy of the hydraulic pump machine 12. The power conversion and energy storage module is electrically connected to the telescopic drive motor and the hydraulic drive mechanism 7 and is used to supply power to the telescopic drive motor and the hydraulic drive mechanism 7.

[0058] This design optimizes the electrical design of the platform. The electrical energy generated by the fan assembly is stored through the power conversion and energy storage module and supplied to the working requirements of the hydraulic pump machine 12, the telescopic drive motor, and the hydraulic drive mechanism 7 when needed. Through such a design, the working power supply of the platform device is completely self-sufficient; preferably, a central control module is provided, which is used to collect the flow data transmitted by the flow sensors 10 and adaptively control the work of the telescopic drive motor and the hydraulic drive mechanism 7 according to the flow data analysis.
