Description

Technical Field

[0002] With the large-scale development of the wind power industry, the remaining exploitable resources of onshore wind farms are decreasing. Offshore wind farms have become a new growth point for the development of the wind power industry. Considering the actual conditions such as offshore fisheries, offshore floating wind turbines will definitely become the future development direction.

[0003] At present, offshore floating wind turbines are still in the initial exploratory stage, and there are still many shortcomings in offshore platforms. For example, in an environment with strong winds and high waves at sea, when the wind speed and wind direction of the offshore platform change, the stress state of the offshore platform will change accordingly, which will inevitably destroy the overall balance of the offshore platform and produce rotation and translation; especially when a typhoon strikes, it will cause the wind power platform to shake violently, which can easily cause the wind power tower and wind turbine blades to shake irregularly and violently, causing the wind turbine blades to come into contact with the tower or sea water and cause damage.

[0066] A stable offshore platform includes a buoy 100, a multi-degree-of-freedom platform 200, a stabilizing and regulating device 300, a fixing device 400, a power device 800, and an offshore monitoring platform 900:

[0067] The buoyancy tank 100 has a hollow cavity;

[0068] The multi-degree-of-freedom platform 200 is placed inside the pontoon 100 and flexibly connected to the pontoon 100;

[0069] A stabilizing and regulating device 300 is rotatably connected to the outer side of the side wall of the buoyancy box 100;

[0070] The rotation stabilization adjustment device 1000 is fixedly connected to the multi-degree-of-freedom platform 200;

[0071] The fixing device 400 is fixedly connected to the bottom of the buoyancy box 100 and the seabed respectively;

[0072] A power device 800 is transmission-connected to the buoyancy box 100;

[0073] The offshore monitoring platform 900 is spaced apart from the pontoon 100 and is signal-connected to the pontoon 100, the multi-degree-of-freedom platform 200, the stabilization adjustment device 300, the rotation stabilization adjustment device 1000, the fixing device 400, and the power device 800, respectively.

[0074] The embodiment of the present application receives the information of the wind speed and direction of the waves through the offshore monitoring platform 900, and adjusts the posture of the pontoon 100 according to the information, so that the tilting force on the pontoon 100 is opposite to the flow direction of the waves and seawater, thereby maintaining a certain balance under the action of the waves and currents; then the damping size of the stability adjustment device 300 is adjusted according to the waves to control the stability of the pontoon 100, and the stability of the platform panel 206 is driven by the multi-degree-of-freedom platform 200. The stability of the platform panel 206 is maintained by the rotation characteristics of the rotation stability regulator, and the adjustment flexible connection of the degree-of-freedom device 201 is reduced to reduce the shaking amplitude of the platform panel 206, thereby maintaining the overall stability of the offshore platform.

[0075] In this embodiment, the pontoon 100 and the multi-degree-of-freedom platform 200 are flexibly connected through the elastic base 202, which can reduce the external vibration transmitted to the platform panel 206 through the legs of the multi-degree-of-freedom platform 200, and the elastic base 202 is connected to the legs of the six-degree-of-freedom device 201. When the six-degree-of-freedom device 201 is adjusted, the force transmitted to the platform panel 206 can be slowed down to maintain a relative balance of the platform panel 206. The elastic base 202 is semi-spherical and is supported by the pressure difference between the inside of the pontoon 100 and the seawater. The elastic base 202 is in the form of a floating body, and uses buoyancy to support the legs and shock absorption of the six-degree-of-freedom device 201.

[0076] It also includes a control system, which receives the wind speed and direction information of the waves from the offshore monitoring platform 900, analyzes the information, and transmits control instructions to the buoy 100, the stabilization adjustment device 300, and the multi-degree-of-freedom platform 200.

[0077] Furthermore, the power device 800 is installed on the upper box 101 or the floating tube 103 of the offshore stable platform, which can better resist the impact of offshore waves and currents on the offshore stable platform.

[0078] In some embodiments of the present application, the buoyancy box 100 includes an upper box body 101, a buoyancy box support rod 102, a floating tube 103 and a fixing device connection seat 107;

[0079] The upper box body 101 accommodates the multi-degree-of-freedom platform 200 and is provided with a damping and shock-absorbing layer. The damping and shock-absorbing layer is a shock-absorbing and vibration-isolating material such as butyl rubber. The floating box support rod 102 is respectively connected to the upper box body 101 and the stabilization adjustment device 300, the floating tube 103 is connected to the bottom of the upper box body 101, and the fixing device connecting seat 107 is respectively connected to the floating tube 103 and the fixing device 400.

[0080] In some embodiments of the present application, the float box 100 also includes a plurality of partitions 104, each of the partitions 104 has a through hole, each of the float tubes 103 has a water inlet 106 and a water outlet 105, respectively, the water inlet 106 and the water outlet 105 are provided with switches, the inner side of the side wall of each float tube 103 is connected to the plurality of partitions 104, the plurality of through holes are staggered with each other and connect the water inlet 106 and the water outlet 105.

[0081] In this embodiment, the partition 104 is vertically or horizontally connected to the wall of the floating tube 103. Furthermore, a mesh smooth damping and shock absorbing material can be installed between the inner wall of the floating tube 103 and the partitions 104 and the partitions 104 to further absorb the impact of the vibration of the waves and currents.

[0082] The offshore stabilization platform transmits the sea wave and sea wind information monitored by the offshore monitoring platform 900 to the offshore stabilization platform, and according to the attitude information of the gyroscope in the pontoon 100, the independent floating pipe water inlet 106 in the windward and wave-facing floating pipes 103 is opened to flow in seawater, and the floating pipe water outlet 105 on the leeward side is opened to discharge water, and the hydraulic winch 401 is controlled to rotate to drive the cable 402 to contract or stretch, until the attitude of the gyroscope is roughly stable, and then all the independent water tank inlets and outlets of the pontoon are closed, and the hydraulic winch 401 is locked. Then the stability adjustment device 300 fixed on the pontoon support rod 102 is adjusted to control the pontoon 100 to be basically stable.

[0083] In some embodiments of the present application, the multi-degree-of-freedom platform 200 includes a six-degree-of-freedom device 201, an elastic base 202, a platform support rod 203, a support rod base 204, a platform panel 206, and a platform flexible connection plate 207;

[0084] The bottom of the upper box 101 is connected to the six-degree-of-freedom device 201 through the elastic base 202, and is connected to the platform support rod 203 through the support rod base 204.

The inner wall of the upper box 101 is wrapped with damping and shock-absorbing materials, which can absorb part of the vibration from waves, currents and other vibrations. The multi-degree-of-freedom platform 200 is accommodated inside. The bottom of the multi-degree-of-freedom platform 200 is located on the elastic base 202 at the bottom of the pontoon. The elastic base 202 can absorb and isolate the vibration of the upper box 101 and part of the vibration from the six-degree-of-freedom device 201, thereby improving the movement flexibility of the six-degree-of-freedom device 201.

Finally, the platform panel 206 is driven to move along the sphere of the platform support rod 203 through the telescopic adjustment of the six-degree-of-freedom device 201 of the multi-degree-of-freedom platform 200, and the platform flexible connecting plate is made of flexible material and is fixedly sealed to the platform panel 206 and the side wall of the upper box body, which can not only ensure that water does not enter the upper box body 101, but also ensure that the platform panel 206 is not affected when adjusted.

[0086] The multi-degree-of-freedom platform 200 is equipped with a gyroscope to monitor the attitude of the multi-degree-of-freedom platform 200. The control system receives the wind speed and direction information of the monitoring platform and integrates the information of the existing platform panel 206 monitored by the gyroscope, and the control system analyzes and sends out control instructions to adjust the water storage in the floating tube 103 and the hydraulic winch 401 to rotate and retract the cable 402, so that the tilting force on the buoyancy box 100 is opposite to the flow direction of the waves and seawater.

The platform panel 206 is surrounded by a six-degree-of-freedom device 201. The support rod cover plate 205 is arranged on the outer side of the platform support rod 203.

[0088] In some embodiments of the present application, the elastic base 202 is fixedly and flexibly connected to the upper box 101 through a flexible member, the flexible member is arch-shaped, the bottom end of the arch is connected to the upper box 101, and the top end is connected to the six-degree-of-freedom device 201;

[0089] Alternatively, the elastic base 202 is movably and flexibly connected to the upper box body 101 via a floating piston.

[0090] In this embodiment, when the bottom of the upper box 101 is fixedly flexibly connected to the elastic base 202, the arch-shaped flexible part is fixed to the bottom of the upper box 101, the lower part of the arch is connected to the seawater, and the top is connected to the platform support foot of the six-degree-of-freedom device 201. Under the action of seawater, it will bulge toward the inside of the upper box 101.

[0091] When the bottom of the upper box 101 is flexibly connected to the elastic base 202 , the floating piston acts as a floating body and floats up under the action of seawater to support the base of the multi-degree-of-freedom platform 200 .

The stabilizing and adjusting device 300 adjusts itself to adapt to the waves and the swaying of the stabilizing platform according to the direction of the waves and the water flow. The method of adapting to the waves and the water flow is to freely move the device in space to drive the damping device to change. The device that freely moves in space is a combination of a multi-degree-of-freedom platform 200, a plurality of degrees-of-freedom swing arms, and a rotating and telescopic device. The damping device is a guide plate device, a telescopic device, a deformation device, etc., which can disturb the waves and the water flow and play a stabilizing role.
