Abstract
Description
Technical Field
[0001] This utility model relates to the field of marine engineering technology, and in particular to a semi-submersible "wind-fishing" integrated platform structure. Background Technology
[0002] In traditional marine development, offshore wind power facilities and aquaculture facilities are often independent, each occupying its own marine space resources. The construction of offshore wind turbines typically disrupts fishing activities in surrounding waters, creating a conflict between fisheries resource development and offshore wind power development. Furthermore, traditional offshore facilities exhibit poor stability in complex sea conditions, making it difficult to guarantee the normal operation of equipment and the safety of personnel. For example, ordinary offshore aquaculture platforms may experience severe shaking or even capsizing in strong winds and waves, affecting aquaculture operations; similarly, the foundation stability of wind turbines is challenged in harsh sea conditions. Simultaneously, existing offshore facilities have low resource utilization efficiency and lack coordination in energy supply and equipment operation regulation. Therefore, there is an urgent need for a new type of marine engineering structure that can effectively integrate offshore wind power and fisheries resources, adapt to complex sea conditions, and improve resource utilization efficiency. Utility Model Content
[0003] To address the shortcomings of existing technologies, this utility model provides a semi-submersible "wind-fishery" integrated platform structure, solving problems such as the independence of existing offshore wind power and fishery facilities, poor adaptability to sea conditions, and low resource utilization efficiency. It achieves synergistic development of offshore wind power generation and aquaculture, improves the platform's stability and operational safety in complex sea conditions, and enhances the comprehensive utilization efficiency of marine resources. To achieve the above objectives, this utility model adopts the following technical solution:
[0004] A semi-submersible "wind-fishing" integrated platform structure includes an upper wind turbine generator set and a lower fishing ground platform. The fishing ground platform consists of six side column buoys and one central buoy. The central buoy is slidably connected to the foundation of the wind turbine generator set and is used to adjust the semi-submersible height according to the liquid level. Each side column buoy is distributed around the central buoy to provide stable buoyancy support. The fishing ground platform is equipped with a ballast water regulation system to automatically adjust the ballast water volume according to changes in sea conditions. The fishing ground platform is also equipped with fishing nets, and two working corridors are provided at the junction of the upper part of the fishing ground platform and the wind turbine generator set.
[0005] Furthermore, a sliding mechanism consisting of a slide rail and a slider is provided between the central pontoon and the wind turbine foundation. The slider is fixedly connected to the wind turbine foundation, the slide rail is located on the top of the central pontoon, and the sliding mechanism is equipped with a locking device for fixing the relative position of the wind turbine and the central pontoon.
[0006] Furthermore, the ballast water regulation system includes a level sensor, a controller, and an electric valve. The level sensor is used to monitor the water level in each float, and the controller controls the opening of the electric valve based on the data from the level sensor to regulate the amount of ballast water in each float.
[0007] Furthermore, the working corridor is located on the upper edge of the fishing platform and is symmetrically distributed. The working corridor is equipped with a non-slip surface and safety railings. One end of the working corridor is connected to the operation and maintenance channel of the wind turbine generator set, and the other end extends to the area above the fishing net of the fishing platform.
[0008] Furthermore, the fishery platform adopts a semi-submersible structure, with the lower half of the central buoy and the side column buoy submerged in water and the upper half exposed above the water surface. The draft of the semi-submersible structure can be adjusted by the ballast water adjustment system, and the sliding connection between the central buoy and the wind turbine foundation, combined with the ballast water adjustment, enables precise control of the platform's semi-submersible height.
[0009] Furthermore, both the side column buoys and the central buoy are hollow cylindrical structures with multiple independent ballast water tanks inside. These multiple independent ballast water tanks are connected to the ballast water regulation system via pipelines.
[0010] Furthermore, the ballast water regulation system also includes a wind speed sensor and a tilt sensor. The wind speed sensor is used to monitor the ambient wind speed, and the tilt sensor is used to monitor the platform's roll and pitch angles. The controller adjusts the ballast water volume based on the data from the wind speed sensor and the tilt sensor.
[0011] Furthermore, the fishing net is set in the area enclosed between the side post buoys and the central buoy, and a floating device is provided on the top of the fishing net.
[0012] Furthermore, the fishing platform is equipped with a fishing net lifting mechanism, which includes a winch and a pulley system for adjusting the depth of the fishing net.
[0013] Furthermore, the power generated by the wind turbine is transmitted via cable to the power distribution system of the fish farm platform, which supplies power to the ballast water regulation system, the fishing net lifting mechanism, and the lighting equipment.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] 1. By combining wind turbine generators with fishing platforms, the integration of offshore wind power and aquaculture is achieved, making full use of marine space resources, reducing the repeated impact of facility construction on the marine ecological environment, and improving the comprehensive utilization efficiency of marine resources.
[0016] 2. The semi-submersible structure and ballast water regulation system enable the platform to automatically adjust its draft and attitude according to different sea conditions. Real-time monitoring of environmental data via level sensors, wind speed sensors, and tilt sensors, along with precise control of electric valves to regulate the ballast water volume in each buoy, effectively improves the platform's stability under severe sea conditions such as high winds and waves, reduces the platform's roll and pitch amplitudes, ensures the safe operation of the platform and equipment, and provides a safer working environment for personnel.
[0017] 3. The work corridor facilitates safe and convenient passage for workers between the wind turbine generators and the fish farm platform. One end connects to the wind turbine generator maintenance access, while the other end extends above the fishing net area, enabling maintenance of the wind turbine generators and daily management and fishing operations of the fish farm. Anti-slip surfaces and safety railings further ensure the safety of workers walking and operating on the corridor.
[0018] 4. The electricity generated by the wind turbine is transmitted to the power distribution system of the fish farm platform through cables, which powers the ballast water regulation system, fishing net lifting mechanism and lighting equipment on the platform. This achieves energy self-sufficiency for the platform, reduces dependence on external energy supply, lowers operating costs, and also improves the independence and reliability of platform operation. Attached Figure Description
[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.
[0023] like Figure 1 As shown in the figure, this utility model embodiment proposes a semi-submersible "wind-fishing" integrated platform structure. A conventional large offshore wind turbine generator 1 is installed on the upper part, and the lower fishing platform consists of six side column buoys 2 and one central buoy 3. The side column buoys 2 are evenly distributed around the central buoy 3, forming a stable support structure through connecting rods 6. Both the side column buoys 2 and the central buoy 3 are hollow cylindrical structures, internally divided into multiple independent ballast water tanks. These ballast water tanks are connected to a ballast water regulation system via pipelines.
[0024] The ballast water regulation system includes a level sensor, a controller, and an electric valve. The level sensor is used to monitor the water level in each float, and the controller controls the opening of the electric valve based on the data from the level sensor to regulate the amount of ballast water in each float.
[0025] Under normal sea conditions, level sensors monitor the water level in each buoy in real time and transmit the data to the controller. The controller, based on a preset program and the current water level, controls the opening of the electric valves to adjust the inflow or outflow of water from each ballast tank, maintaining the platform in a stable semi-submerged state. At this time, the central buoy 3 is connected to the wind turbine generator 1 foundation via a sliding mechanism consisting of a slide rail and a slider. The slider is fixed to the bottom of the wind turbine generator 1 foundation, and the slide rail is installed on the top plane of the central buoy 3. When it is necessary to adjust the platform's semi-submerged height according to the power generation requirements of the wind turbine generator 1 or changes in sea conditions, the locking device is released from the sliding mechanism. By adjusting the ballast water volume, the central buoy 3 slides vertically relative to the wind turbine generator 1 foundation. Once a suitable height is reached, the locking device is used to fix the relative position of the two, achieving precise adjustment of the platform's semi-submerged height.
[0026] The wind speed sensor in the ballast water regulation system is installed high on the platform to monitor the ambient wind speed in real time and transmit the wind speed data to the controller. Tilt sensors are distributed at key locations on the platform to monitor the platform's roll and pitch angles. When encountering strong winds and waves, the wind speed sensor detects increased wind speed, and the tilt sensor detects that the platform's roll or pitch angle exceeds the normal range. After receiving this data, the controller calculates the required ballast water volume and the regulation strategy for each ballast tank based on a preset control algorithm. Then, the controller issues commands to control the opening of the electric valves, injecting or dewatering water into the corresponding ballast tanks. For example, when the platform tilts to one side, the controller controls the injection of water into the ballast tank of the opposite side column buoy 2, increasing the weight on that side, thereby balancing the platform, reducing the tilt angle, and improving the platform's stability in harsh sea conditions.
[0027] The work corridor 5 is located symmetrically on the upper edge of the fish farm platform. Its surface is paved with anti-slip material, and sturdy safety railings are installed on both sides. The railing height meets safety standards, effectively preventing accidental falls by workers. When performing maintenance work on wind turbine generator 1, workers can enter the generator through the connection between one end of the work corridor 5 and the maintenance passage of wind turbine generator 1 for inspection and repair. During aquaculture management and fishing operations, workers can walk along the work corridor 5 to the area above fishing net 4, using the lifting mechanism of fishing net 4 to adjust the depth of fishing net 4, feed the fish, and harvest aquatic products. The design of the work corridor 5 greatly improves the convenience and safety of operations, reducing the risks for workers moving between different areas.
[0028] Fishing net 4 is set up in the area enclosed between the side buoy 2 and the central buoy 3, and a floating device is installed on top to allow the fishing net 4 to float at a suitable position on the water surface. When it is necessary to adjust the depth of the fishing net 4, the operators activate the lifting mechanism of the fishing net 4 on the fish farm platform. The winch of the lifting mechanism of the fishing net 4 is connected to the fishing net 4 through a steel wire rope and a pulley system. When the winch rotates, the fishing net 4 is raised or lowered by the winding and unwinding of the steel wire rope, so as to achieve precise adjustment of the depth of the fishing net 4 to adapt to the living habits of different fish species and the needs of aquaculture and fishing.
[0029] The electrical energy generated by wind turbine generator 1 is transmitted via cable to the power distribution system of the fishing platform. The power distribution system allocates and manages the electrical energy, providing a stable power supply to the electric valves in the ballast water regulation system, the winch of the fishing net 4 lifting mechanism, and the lighting equipment on the platform. For example, during nighttime fishing operations, the lighting equipment uses the power supplied by the power distribution system to illuminate the area around fishing net 4, facilitating operations for personnel; the ballast water regulation system and the fishing net 4 lifting mechanism, driven by electricity, can respond quickly and accurately to control commands, ensuring the normal operation of the platform and fishing operations.
[0030] The locking device is used to fix the relative position of the wind turbine generator 1 and the central pontoon 3, ensuring the structural stability of the platform under normal operation and harsh sea conditions. The locking device can take various forms, such as a mechanical locking pin type. This device includes a locking hole mounted on the slider and a retractable locking pin mounted on the side of the slide rail. When locking is required, a hydraulic or electric drive mechanism pushes the locking pin out and inserts it into the locking hole on the slider, fixing the slider to the slide rail, thereby achieving relative fixation between the wind turbine generator 1 and the central pontoon 3. When adjusting the platform's semi-submersible height, the drive mechanism retracts the locking pin, releasing the lock and allowing the slider to slide freely on the slide rail.
[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
