Description

Technical Field

[0001] The present invention relates to the technical field of offshore platforms, and specifically to a floating offshore platform with a balance self - adjustment function. Background Art

[0002] With the gradual saturation of the development of near - shore wind energy resources, humans have gradually focused their attention on waters with a water depth exceeding 50m. Therefore, the floating offshore wind power technology has become the main technical route for the development of deep - sea wind energy resources; a floating wind turbine usually consists of three main parts: a wind turbine, a floating foundation, and a mooring system. Among them, the mooring system is mainly used for the positioning of the wind turbine and the floating foundation. In addition to considering the displacement allowed by the dynamic cable and the extreme loads under typhoon conditions, the mooring system also needs to control the pitch angle of the wind turbine to ensure the power generation efficiency; the mooring system usually consists of mooring chains, connectors, anchors, chain stoppers, and tensioning devices. Usually, a set of systems is composed of three mooring anchor legs, and each group includes one to three mooring chains; the tension - leg floating platform has become an important development direction because its mooring radius and motion response are more suitable for the large - scale construction of floating wind power.

[0003] The prior art (CN116424505A, a floating wind power platform for wind - fishing combination and a mooring system) mentions using steel wire ropes or polyester cables to moor the platform, but this process requires divers to go underwater for connection, or pulling the components onto the deck for connection, with high operation difficulty and long installation cycle. Summary of the Invention

[0004] The purpose of the present invention is to provide a floating offshore platform with a balance self - adjustment function to solve the problems raised in the prior art.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

[0006] A floating offshore platform with a balance self - adjustment function is composed of a platform and several mooring devices. The platform is fixed to the seabed through the mooring devices. The mooring device consists of a pile foundation, a steel cable, and two fixing plates. The two fixing plates are respectively arranged on the platform and the pile foundation, and the pile foundation is fixed on the seabed.

[0007] Preferably, a steel cable is arranged between the fixing plate on the platform and the fixing plate on the pile foundation. A tongue plate is arranged on the fixing plate, and a locking pin is arranged between the tongue plate and the fixing plate. The tongue plate is rotatably connected to the fixing plate through the locking pin.

[0008] Before the fixing plate is lowered into the water with the pile foundation, rotate the locking pins on both sides clockwise to open the locking pins, then install and thread through to complete the connection between the tongue plate and the swivel thimble. Subsequently, move the tongue plate between the two locking pins, and fix the tongue plate on the fixing plate through the locking of the locking pins.

[0009] Preferably, a swivel socket is provided between the steel cable and the tongue plate. One end of the swivel socket is connected to the steel cable, and the other end of the swivel socket is rotatably connected to the tongue plate. The maximum allowable rotation angle of the swivel socket is ±15°.

[0010] By setting the allowable rotation angle of the swivel socket, when the platform has a balance offset, it will not generate a large tensile force on the steel cable, thus preventing the force on the swivel socket from increasing and causing a fracture.

[0011] Preferably, a protective frame is provided on the side of the pile foundation close to the platform. The protective frame is fixed on the seabed. An inclined plate is provided on the side of the protective frame close to the pile foundation, and the inclined plate inclines towards the side close to the pile foundation.

[0012] The protective frame and the pile foundation are installed together. When the steel cable is pre-laid on the seabed after being connected to the pile foundation, the steel cable is slowly released so that the steel cable falls on the surface of the protective frame, preventing the steel cable from being damaged by excessive bending when pre-laying on the seabed after the connection is completed.

[0013] Preferably, a guiding block is provided at the bottom of the platform. A gravity block is provided on the side of the guiding block away from the platform. The platform, the guiding block and the gravity block are combined into an inverted cone.

[0014] The platform, the guiding block and the gravity block are combined into an inverted cone, which causes the center of the platform to descend, and the area of the platform is larger than the area of the gravity block, increasing the buoyancy of the platform. On the basis of the increased buoyancy, the center of gravity descends, improving the balance of the platform. When the platform is jolted by the influence of sea waves, it can return to the balanced state faster.

[0015] Preferably, the top area of the guiding block is larger than the bottom area of the guiding block, and the side of the guiding block is in a spiral contraction shape.

[0016] Since the guiding block is below the sea surface, when the seawater flows under the influence of ocean currents, the seawater encounters the guiding block and is affected by the spiral contraction side of the guiding block, causing the seawater to flow from the top of the guiding block to the bottom of the guiding block. Then the seawater will flow to the turbine, so that the force generated by the impact of the seawater is transferred from hitting the side of the guiding block to hitting the turbine, realizing the transfer of the seawater impact force, reducing the impact of the seawater on the guiding block, and improving the overall balance of the platform.

[0017] Preferably, a rotating groove is provided between the guiding block and the gravity block. A turbine is provided in the rotating groove. The turbine is rotatably connected to the rotating groove. A magnet is provided inside the turbine, and an electromagnetic coil is provided at the center of the rotating groove.

[0018] The seawater affected by the side of the guiding block flows towards the side close to the rotating groove. When it flows to the rotating groove, it encounters the turbine, thereby pushing the turbine to rotate. The turbine drives the magnet arranged inside to rotate, and then the electromagnetic coil in the rotating groove generates an induced magnetic field, thus achieving the effect of generating electricity by the impact of seawater. Wind turbines can also be set on the surface of the platform, enabling two different power generation forms, namely wind power and ocean current power generation, to proceed simultaneously, thereby improving the utilization rate of resources. Since the depths of the sea where the turbine and the guiding block are located are different, the seawater at the same depth as the turbine can directly impact the turbine, thereby achieving the power generation effect. Or the seawater flowing in parallel and the seawater guided by the guiding block act together on the turbine, thereby increasing the rotation speed of the turbine and improving the power generation efficiency.

[0019] Preferably, a plurality of diversion grooves are arranged inside the platform. The plurality of diversion grooves are evenly arranged on each side of the platform. A rotating plate is arranged on the side of the diversion groove close to the side of the platform. A motor is arranged inside the platform. The driving shaft of the motor is connected to the rotating shaft of the rotating plate. The rotating plate is rotationally connected to the diversion groove. A gyroscope is also arranged inside the platform.

[0020] Preferably, the plurality of diversion grooves converge from the side of the platform towards the center of the platform. The height of the diversion groove on the side close to the center of the platform is greater than the height of the diversion groove on the side close to the side of the platform.

[0021] When encountering large waves and winds, the controller controls the motor to start. The driving shaft of the motor drives the rotating shaft of the rotating plate to rotate, so that the axis of the rotating plate is parallel to the axis of the diversion groove. At this time, the diversion groove is communicated with the external seawater. Then, during the process of seawater flowing through the side of the platform, part of the seawater flows into the diversion groove, thereby weakening the impact of the seawater on the side of the platform. And after the seawater enters the diversion groove, the weight of the seawater acts on the platform, causing the platform to sink a certain distance towards the side close to the seabed, and then reducing the height of the platform on the sea surface, so that the influence of the waves and winds on the platform is weakened.

[0022] When the balance of the platform is shifted, the controller controls the motor to rotate continuously according to the gyroscope arranged inside the platform, so that the driving shaft of the motor continuously controls the deflection of the rotating plate, and an included angle is formed between the axis of the rotating plate and the axis of the diversion groove.

[0023] When the side of the rotating plate far from the diversion groove approaches the gravity block, at this time, the impact force of the seawater acts on the side of the rotating plate close to the platform, and then the seawater will push the rotating plate to move towards the side close to the gravity block, that is, drive the platform to sink.

[0024] When the side of the rotating plate away from the diversion groove approaches the platform, the impact force of the seawater will act on the side of the rotating plate close to the gravity block at this time. Then, the seawater will push the rotating plate towards the side close to the platform, that is, drive the platform to float upward.

[0025] Through the continuous deflection of the rotating plate, the seawater acts on the two surfaces of the rotating plate, thereby using the impact force of the seawater to achieve the balance adjustment of the platform.

[0026] Preferably, a plurality of air holes are provided on the surface of the gravity block, an air pump is provided inside the gravity block, the air pump is connected to the top of the platform through a pipeline, and the air pump is communicated with the air holes.

[0027] The controller controls the air pump to start. The air pump extracts the external air. The external air is extracted into the gravity block through the pipeline and output to the air holes. The gas ejected from the air holes forms tiny bubbles in the seawater. The tiny bubbles will move towards the side close to the sea surface. Also, since the platform, the guiding block and the gravity block are combined into an inverted cone shape, the tiny bubbles can move along the sides of the gravity block, the guiding block and the platform, thereby reducing the frictional force between the seawater and the side of the platform, and then reducing the adhesion force of marine organisms adhering to the side of the platform, and extending the growth cycle of marine organisms on the side of the platform.

[0028] Compared with the prior art, the beneficial effects of the present invention are:

[0029] 1. The seawater flows through the guiding block and is affected by the spiral shrinking side of the guiding block, so that the seawater flows from the top of the guiding block to the bottom of the guiding block. Then, the seawater will flow towards the turbine, so that the acting force generated by the impact of the seawater is changed from hitting the side of the guiding block to hitting the turbine, realizing the transfer of the impact force of the seawater, reducing the impact of the seawater on the guiding block, and improving the overall balance of the platform.

[0030] 2. When the balance of the platform is offset, the controller controls the motor to rotate continuously according to the gyroscope set in the platform, so that the motor drive shaft continuously controls the deflection of the rotating plate, so that the axis of the rotating plate forms an angle with the axis of the diversion groove; when the side of the rotating plate away from the diversion groove approaches the gravity block, the impact force of the seawater will act on the side of the rotating plate close to the platform at this time. Then, the seawater will push the rotating plate towards the side close to the gravity block, that is, drive the platform to sink; when the side of the rotating plate away from the diversion groove approaches the platform, the impact force of the seawater will act on the side of the rotating plate close to the gravity block at this time. Then, the seawater will push the rotating plate towards the side close to the platform, that is, drive the platform to float upward.

[0031] Through the continuous deflection of the rotating plate, the seawater acts on the two surfaces of the rotating plate, thereby using the impact force of the seawater to achieve the balance adjustment of the platform.

[0032] 3. The tiny bubbles generated by the air pump can move along the sides of the gravity block, guiding block, and platform, thereby reducing the friction between the seawater and the sides of the platform, further reducing the adhesion force of marine organisms attaching to the sides of the platform, and extending the cycle of marine organisms growing on the sides of the platform.

[0053] The working principle of the present invention:

[0054] The guiding block 11 is located below the sea surface. When seawater flows under the influence of ocean currents, the seawater encounters the guiding block 11 and is affected by the spiral shrinking side of the guiding block 11, causing the seawater to flow from the top of the guiding block 11 to the bottom of the guiding block 11. Then the seawater will flow towards the turbine 14, so that the acting force generated by the impact of the seawater is changed from hitting the side of the guiding block 11 to hitting the turbine 14, realizing the transfer of the seawater impact force and reducing the impact of the seawater on the guiding block 11;

[0055] The seawater affected by the side of the guiding block 11 flows towards the side close to the rotating groove 13. When it flows to the rotating groove 13, it encounters the turbine 14, thereby pushing the turbine 14 to rotate. The turbine 14 drives the magnet arranged inside to rotate, and then the electromagnetic coil in the rotating groove 13 generates an induced magnetic field, thus realizing the effect of generating electricity by using the impact of seawater. A wind power generator set can also be arranged on the surface of the platform 1, enabling two different power generation forms, namely wind power and ocean current power generation, to be carried out simultaneously, thereby improving the utilization rate of resources. Since the sea depths where the turbine 14 and the guiding block 11 are located are different, the seawater at the same sea depth as the turbine 14 can directly impact the turbine 14, thereby realizing the power generation effect, or the seawater flowing in parallel and the seawater guided by the guiding block 11 act on the turbine 14 together, thereby increasing the rotation speed of the turbine 14;

[0056] When encountering large waves and strong winds, the controller controls the motor to start. The driving shaft of the motor drives the rotating shaft of the rotating plate 16 to rotate, so that the axis of the rotating plate 16 is parallel to the axis of the diversion groove 15. At this time, the diversion groove 15 is communicated with the outside seawater. Then, when the seawater flows past the side of the platform 1, part of the seawater flows towards the diversion groove 15 and enters the inside of the diversion groove 15, thereby weakening the impact of the seawater on the side of the platform 1. And after the seawater enters the diversion groove 15, the weight of the seawater acts on the platform 1, causing the platform 1 to sink a certain distance towards the side close to the seabed, and then reducing the height of the platform 1 above the sea surface, so that the influence of the platform 1 by the waves and strong winds is weakened;

[0057] When the balance of platform 1 is offset, the controller controls the motor to rotate continuously according to the gyroscope set inside platform 1, so that the motor drive shaft continuously controls the deflection of rotating plate 16, making the axis of rotating plate 16 form an angle with the axis of the shunt groove 15;

[0058] When the side of rotating plate 16 away from shunt groove 15 approaches gravity block 12, at this time the impact force of seawater will act on the side of rotating plate 16 close to platform 1, and then the seawater will push rotating plate 16 to move towards the side close to gravity block 12, that is, drive platform 1 to sink;

[0059] When the side of rotating plate 16 away from shunt groove 15 approaches platform 1, at this time the impact force of seawater will act on the side of rotating plate 16 close to gravity block 12, and then the seawater will push rotating plate 16 to move towards the side close to platform 1, that is, drive platform 1 to float;

[0060] Through the continuous deflection of rotating plate 16, the seawater acts on the two surfaces of rotating plate 16, thereby realizing the balance adjustment of platform 1 by using the impact force of seawater;

[0061] The controller controls the air pump to start. The air pump extracts the external air, and the external air is extracted through the pipeline into gravity block 12 and output to air holes 121. The gas ejected from air holes 121 forms tiny bubbles in the seawater. The tiny bubbles will move towards the side close to the sea surface. Also, since platform 1, guiding block 11 and gravity block 12 are combined into an inverted cone shape, the tiny bubbles can move along the sides of gravity block 12, guiding block 11 and platform 1, thereby reducing the frictional force between the seawater and the side of platform 1, and further reducing the adhesion force of marine organisms adhering to the side of platform 1.

[0062] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
