Description

Technical Field

[0001] The invention relates to the technical field of marine platforms, in particular to a floating marine platform with a balancing and self-regulating function. Background Art

[0002] As offshore wind energy resources are gradually saturated, humans are gradually focusing their attention on sea areas with a water depth of more than 50m. Floating offshore wind power technology has therefore become the main technical route for the development of deep-sea wind energy resources. Floating wind turbines are usually composed of three major parts: wind turbines, floating foundations and mooring systems. The mooring system is mainly used for positioning wind turbines and floating foundations. In addition to considering the allowable displacement of dynamic cables and extreme loads under typhoon conditions, the mooring system also needs to control the pitch angle of the wind turbine to ensure power generation efficiency. The mooring system is usually composed of mooring chains, connectors, anchors, stop chains and tensioning devices. It is usually composed of three groups of mooring anchor legs, each of which 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 large-scale construction of floating wind power.

[0003] The prior art (CN116424505A, a floating wind power platform and mooring system combining wind and fishing) mentions the use of steel wire ropes or polyester cables to moor the platform, but this process requires divers to go into the water for connection, or pull the components onto the deck for connection, which is difficult to operate and has a long installation period. Summary of the invention

[0004] The object of the present invention is to provide a floating marine platform with a balancing and self-regulating function to solve the problems raised in the prior art.

[0005] To achieve the above object, the present invention provides the following technical solutions: A floating marine platform with a balancing and self-adjusting function consists of a platform and a plurality of mooring devices. The platform is fixed to the seabed through the mooring devices. The mooring devices consist 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. The pile foundation is fixed on the seabed.

[0006] Preferably, a steel cable is provided between the fixed plate on the platform and the fixed plate on the pile foundation, a tongue plate is provided on the fixed plate, a locking pin is provided between the tongue plate and the fixed plate, and the tongue plate is rotatably connected to the fixed plate via the locking pin.

[0007] Before the fixed plate is launched into the water with the pile foundation, the locking pins on both sides are rotated clockwise to open the locking pins, and then the tongue plate is installed and put on to complete the connection between the tongue plate and the rotating cable joint. Subsequently, the tongue plate is moved between the two locking pins and fixed to the fixed plate by locking the locking pins.

[0008] Preferably, a rotating knot is provided between the steel cable and the tongue plate, one end of the rotating knot is connected to the steel cable, and the other end of the rotating knot is rotatably connected to the tongue plate, and the maximum allowable rotation angle of the rotating knot is ±15°.

[0009] By setting the allowable rotation angle of the rotating cable joint, when the platform is balanced and offset, it will not generate a large pulling force on the steel cable, thereby increasing the force on the rotating cable joint and causing it to break.

[0010] Preferably, a protection frame is provided on the side of the pile foundation close to the platform, the protection frame is fixed on the seabed, and an inclined plate is provided on the side of the protection frame close to the pile foundation, the inclined plate is inclined toward the side close to the pile foundation.

[0011] The protection frame is installed together with the pile foundation. When the steel cable is connected to the pile foundation and pre-laid on the seabed, the steel cable is slowly released so that it falls on the surface of the protection frame to prevent the steel cable from being damaged by bending when it is pre-laid on the seabed after the connection is completed.

[0012] Preferably, a guide block is provided at the bottom of the platform, a gravity block is provided on a side of the guide block away from the platform, and the platform, the guide block and the gravity block are combined into an inverted cone.

[0013] The platform, guide block and gravity block are combined into an inverted cone, so that the center of the platform drops, and the area of ​​the platform is larger than the area of ​​the gravity block, so that the buoyancy of the platform increases. On the basis of the increased buoyancy, the center of gravity drops, which improves the balance of the platform. When the platform is affected by waves and bumps, it returns to a balanced state more quickly.

[0014] Preferably, the top area of ​​the guide block is larger than the bottom area of ​​the guide block, and the side of the guide block is in a spiral contraction shape.

[0015] Since the guide block is located below the sea surface, when the seawater is affected by the ocean current and flows, it encounters the guide block and is affected by the spirally contracted side of the guide block, causing the seawater to flow from the top of the guide block to the bottom of the guide block, and then the seawater will flow to the turbine, so that the force generated by the impact of the seawater is transformed from hitting the side of the guide block to hitting the turbine, thereby realizing the transfer of the impact force of the seawater, reducing the impact of the seawater on the guide block, and improving the overall balance of the platform.

[0016] Preferably, a rotating groove is provided between the guide 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.

[0017] The seawater affected by the side of the guide block flows to the side close to the rotating groove. When it flows to the rotating groove, it encounters the turbine, thereby driving the turbine to rotate, so that the turbine drives the magnets installed inside to rotate, and then the electromagnetic coil in the rotating groove generates an induced magnetic field, thereby achieving the effect of generating electricity by the impact of seawater. Wind turbines can also be installed on the surface of the platform, so that two different forms of power generation, wind power and ocean current, can be carried out simultaneously, thereby improving the utilization rate of resources. Since the turbine and the guide block are located at different sea depths, the seawater at the same sea depth as the turbine can directly impact the turbine, thereby achieving the power generation effect, or the parallel flowing seawater and the seawater guided by the guide block act together on the turbine, thereby increasing the rotation speed of the turbine, thereby improving the power generation efficiency.

[0018] Preferably, a plurality of diverter grooves are provided inside the platform, and the plurality of diverter grooves are evenly arranged on each side of the platform. A rotating plate is provided on one side of the diverter groove close to the side of the platform. A motor is provided inside the platform, and the driving shaft of the motor is connected to the rotating shaft of the rotating plate. The rotating plate is rotatably connected to the diverter groove. A gyroscope is also provided inside the platform.

[0019] Preferably, a plurality of the diverter grooves are gathered from the side of the platform toward the center of the platform, and the height of the diverter groove close to the center of the platform is greater than the height of the diverter groove close to the side of the platform.

[0020] When encountering a large wind and wave, the controller controls the motor to start, and 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 diverter slot. At this time, the diverter slot is connected with the external seawater, and then when the seawater flows through the side of the platform, part of the seawater flows to the diverter slot and enters the inside of the diverter slot, thereby reducing the impact of the seawater on the side of the platform. After the seawater enters the diverter slot, the weight of the seawater will act on the platform, causing the platform to sink a certain distance to the side close to the seabed, thereby reducing the height of the platform above the sea surface, so that the platform is less affected by wind and waves; 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 diverter slot; When the side of the rotating plate away from the diversion trough approaches the gravity block, the impact force of the seawater will act on the side of the rotating plate close to the platform, and then the seawater will push the rotating plate to move to the side close to the gravity block, that is, drive the platform to sink; When the rotating plate is away from the diversion trough and approaches the platform, the impact force of the seawater will act on the side of the rotating plate close to the gravity block, and then the seawater will push the rotating plate to move to the side close to the platform, that is, drive the platform to float; Through the continuous deflection of the rotating plate, the seawater acts on the two surfaces of the rotating plate, so that the balance adjustment of the platform is achieved by utilizing the impact force of the seawater.

[0021] Preferably, a plurality of air holes are arranged on the surface of the gravity block, an air pump is arranged inside the gravity block, the air pump is connected to the top of the platform through a pipeline, and the air pump is connected to the air holes.

[0022] The controller controls the air pump to start, and the air pump draws outside air. The outside air is drawn into the gravity block through the pipe and output to the pores. The gas ejected by the pores forms tiny bubbles in the seawater. The tiny bubbles will move to the side close to the sea surface. Since the platform, guide block and gravity block are combined into an inverted cone, the tiny bubbles can move along the sides of the gravity block, guide block and platform, thereby reducing the friction between the seawater and the side of the platform, thereby reducing the adhesion of marine organisms to the side of the platform, and extending the growth period of marine organisms on the side of the platform.

[0023] Compared with the prior art, the present invention has the following beneficial effects: 1. When seawater flows through the guide block, it is affected by the spirally contracted side of the guide block, causing the seawater to flow from the top of the guide block to the bottom of the guide block, and then the seawater will flow to the turbine, so that the force generated by the impact of the seawater is transformed from hitting the side of the guide block to hitting the turbine, realizing the transfer of the impact force of the seawater, reducing the impact of the seawater on the guide block, and improving the overall balance of the platform.

[0024] 2. When the balance of the platform is offset, the controller controls the motor to rotate continuously according to the gyroscope installed 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 diverter slot; when the rotating plate is away from the diverter slot and close to the gravity block, the impact force of the sea water will act on the side of the rotating plate close to the platform, and then the sea water will push the rotating plate to move to the side close to the gravity block, that is, drive the platform to sink; when the rotating plate is away from the diverter slot and close to the platform, the impact force of the sea water will act on the side of the rotating plate close to the gravity block, and then the sea water will push the rotating plate to move to the side close to the platform, that is, drive the platform to float; Through the continuous deflection of the rotating plate, the seawater acts on the two surfaces of the rotating plate, so that the balance adjustment of the platform is achieved by utilizing the impact force of the seawater.

[0025] 3. The tiny bubbles generated by the air pump can move along the gravity block, guide block and the side of the platform, thereby reducing the friction between the seawater and the side of the platform, thereby reducing the adhesion of marine organisms to the side of the platform and extending the growth period of marine organisms on the side of the platform.

[0038] Working principle of the present invention: The guide block 11 is located below the sea surface, so that when the seawater is affected by the ocean current and flows, the seawater encounters the guide block 11 and is affected by the spirally contracted side of the guide block 11, so that the seawater flows from the top of the guide block 11 to the bottom of the guide block 11, and then the seawater flows to the turbine 14, so that the force generated by the impact of the seawater is converted from hitting the side of the guide block 11 to hitting the turbine 14, thereby realizing the transfer of the impact force of the seawater and reducing the impact of the seawater on the guide block 11; The seawater affected by the side of the guide block 11 flows toward the side close to the rotating groove 13. When it flows to the rotating groove 13, it encounters the turbine 14, thereby driving the turbine 14 to rotate, so that the turbine 14 drives the magnets arranged inside to rotate, and then the electromagnetic coil in the rotating groove 13 generates an induced magnetic field, thereby realizing the effect of generating electricity by the impact of seawater. A wind turbine set can also be arranged on the surface of the platform 1, so that two different forms of power generation, wind power and ocean current, can be carried out simultaneously, thereby improving the utilization rate of resources. Since the turbine 14 and the guide block 11 are located at different sea depths, the seawater at the same sea depth as the turbine 14 can directly impact the turbine 14, thereby achieving the power generation effect, or the seawater flowing in parallel and the seawater guided by the guide block 11 act together on the turbine 14, thereby increasing the rotation speed of the turbine 14; When encountering a large wind and wave, the controller controls the motor to start, and 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 diverter slot 15. At this time, the diverter slot 15 is connected with the external seawater, and then when the seawater flows through the side of the platform 1, part of the seawater flows to the diverter slot 15 and enters the inside of the diverter slot 15, thereby reducing the impact of the seawater on the side of the platform 1. After the seawater enters the diverter slot 15, the weight of the seawater will act on the platform 1, causing the platform 1 to sink a certain distance to the side close to the seabed, thereby reducing the height of the platform 1 above the sea surface, so that the platform 1 is less affected by wind and waves; When the balance of the platform 1 is offset, the controller controls the motor to rotate continuously according to the gyroscope provided in the platform 1, so that the motor drive shaft continuously controls the deflection of the rotating plate 16, so that the axis of the rotating plate 16 forms an angle with the axis of the diverter slot 15; When the side of the rotating plate 16 away from the diversion trough 15 approaches the gravity block 12, the impact force of the seawater will act on the side of the rotating plate 16 close to the platform 1, and then the seawater will push the rotating plate 16 to move to the side close to the gravity block 12, that is, drive the platform 1 to sink; When the side of the rotating plate 16 away from the diversion trough 15 approaches the platform 1, the impact force of the seawater will act on the side of the rotating plate 16 close to the gravity block 12, and then the seawater will push the rotating plate 16 to move to the side close to the platform 1, that is, drive the platform 1 to float; By continuously deflecting the rotating plate 16, the seawater acts on the two surfaces of the rotating plate 16, so that the balance adjustment of the platform 1 is achieved by utilizing the impact force of the seawater; The controller controls the air pump to start, and the air pump draws air from the outside. The outside air is drawn into the gravity block 12 through the pipeline and output to the air hole 121. The gas ejected by the air hole 121 forms tiny bubbles in the seawater. The tiny bubbles will move to the side close to the sea surface. Since the platform 1, the guide block 11 and the gravity block 12 are combined into an inverted cone, the tiny bubbles can move along the sides of the gravity block 12, the guide block 11 and the platform 1, thereby reducing the friction between the seawater and the side of the platform 1, and thereby reducing the adhesion of marine organisms to the side of the platform 1.
