The existing equipment includes semi-submersible floating wind turbine foundation, tension leg wind turbine foundation, barge wind turbine foundation, etc.

[0003] The foundation of a semi-submersible floating wind turbine is usually composed of columns, buoys, cross braces and other components. The columns and buoys are connected by a specific connection method, so that the wind turbine can stably support the offshore wind turbine to operate on the sea surface, and then convert the energy of ocean waves into electrical energy or other usable forms of energy through built-in or attached wave energy conversion devices;

[0004] As for the existing wave energy floating semi-submersible offshore wind turbine foundation, firstly, in the wave energy conversion device, the vibrating float is the key to achieve conversion, and the silt such as seaweed attached to the surface of the oscillating float will significantly increase the resistance of the float to the movement in the water, resulting in a decrease in power generation efficiency; secondly, many marine organisms are sensitive to electric and magnetic fields.

[0017] The present invention provides a wave energy floating offshore wind turbine foundation, which has the following beneficial effects:

[0018] 1. After the present invention is started by rotating the motor, the sun gear, the planetary gear and the ring gear are meshed with each other to drive the connecting shaft to rotate, and the connecting shaft then rotates the mounting plate. The brush on the inner side of the mounting plate can gently scrape off the silt such as seaweed attached to the surface of the oscillating float, thereby keeping the surface of the oscillating float clean and maintaining its good hydrodynamic performance, ensuring that it can efficiently convert wave energy into mechanical energy, and then ensuring that the subsequent generator can continuously and stably convert mechanical energy into electrical energy, effectively solving the problem of reduced power generation efficiency due to the attachment of silt, improving the power generation efficiency and operating stability of the entire equipment, reducing the downtime and maintenance time caused by the silt problem, reducing maintenance costs and extending the service life of the equipment.

[0019] 2. The shielding net between the assembly rings of the present invention can effectively eliminate most of the electromagnetic interference generated in the power generation process, reduce the attraction to marine life, and thus avoid the abnormal aggregation of marine life due to the influence of the electric field. When the fixed ring slides to the middle section of the fixed shaft, the blocking cap no longer has a blocking effect on the baffle, and the fixed spring will release the stored elastic potential energy to push the baffle to pop out, thereby stably fixing the interception net on the fixed shaft. The interception net is made of high-strength, corrosion-resistant material with a suitable mesh size, which can effectively block fish and other marine life from swimming near the installation platform, reducing the risks of entanglement and collision between marine life and equipment, ensuring the safe and stable operation of the equipment, and at the same time it is also beneficial to maintain the natural balance and stability of the surrounding marine ecological environment, and reduce the adverse effects of the aggregation of marine life on the normal operation of the equipment and the marine ecology.

[0020] 3. In the present invention, the temperature sensor in the heating mechanism can monitor the temperature of the buoy in real time. When the temperature is too low, the heating wire starts to generate heat, and the heat is evenly transferred through the conduction plate to heat the buoy, effectively preventing the seawater from freezing on the surface of the buoy. When necessary, the spray pump is started to spray the antifreeze in the antifreeze tank evenly onto the surface of the buoy through the water inlet pipe and the water outlet pipe by the nozzle, forming an antifreeze protective film, lowering the freezing point on the surface of the buoy, preventing freezing or melting the ice layer that has been formed, thereby maintaining the original buoyancy balance of the buoy, ensuring that the fan foundation can operate normally in the cold marine environment and will not tilt, sink or other dangerous conditions due to ice problems, thereby improving the applicability and reliability of the equipment in low-temperature and high-ice risk sea areas.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings of the present invention specification to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Please refer to the attached Figure 1 -Attached Figure 3 and attached Fig.10 The embodiment of the present invention provides a wave energy floating offshore wind turbine foundation, including a plurality of buoys 1, the plurality of buoys 1 are connected by a mounting assembly 2, the mounting assembly 2 includes a plurality of longitudinally arranged connecting columns 203, a plurality of longitudinally arranged connecting columns 203 are equidistantly arranged between the plurality of buoys 1, a crossbeam 202 is arranged in the middle of the bottom connecting column 203, a mounting platform 201 is arranged near one end of the plurality of crossbeams 202, and the top of the mounting platform 201 is fixedly connected to the bottom of the power generating wind turbine 11;

[0034] The buoy 1 plays an important role in providing buoyancy and stabilizing the entire infrastructure in the marine environment. Multiple buoys 1 are firmly connected through specially designed mounting components 2 to ensure that the entire foundation can maintain structural integrity and stability under complex marine dynamics such as waves and currents. The main function of the connecting column 203 is to effectively transmit the force between the buoys 1. Whether it is to withstand the gravity distribution of the entire foundation in a static state, or to cope with various complex forces generated by the impact of waves in a dynamic environment, they can be reasonably dispersed and transmitted through the connecting column 203, thereby ensuring the collaborative working performance of the entire infrastructure;

[0035] As a lateral support structure, the main function of the crossbeam 202 is to enhance the lateral stability of the entire foundation structure. It can effectively prevent the buoy 1 from excessive lateral displacement or deformation when subjected to lateral forces such as lateral current impact or lateral forces of wind and waves, further enhancing the anti-interference ability of the entire foundation in a complex marine environment.

[0036] The mounting platform 201 not only provides a horizontal and stable mounting surface for the wind turbine 11, but also undertakes the key task of transmitting the buoyancy provided by the buoy 1 to the wind turbine 11, so that the wind turbine 11 can maintain a stable working posture in the offshore environment and effectively convert wind energy into electrical energy.

[0037] Please refer to the attached Figure 8 The interior of the buoy 1 is provided with a heating mechanism 9 and an antifreeze mechanism 10. The heating mechanism 9 includes a conduction plate 901 and a plurality of longitudinally arranged heating wires 902. The interior of the buoy 1 is provided with a conduction plate 901 and a plurality of longitudinally arranged heating wires 902 from the outside to the inside. The buoy 1 is provided with a temperature sensor 903. The conduction plate 901 is made of a material with good thermal conductivity. Its main function is to transfer the heat generated by the heating wire 902 to the entire inner surface of the buoy 1 evenly and efficiently, thereby achieving comprehensive heating and temperature rise of the buoy 1. The heating wire 902, as the core component for heat generation, can quickly generate heat and generate a large amount of heat energy when receiving a power-on command. The temperature sensor 903 can accurately sense the temperature changes inside and on the surface of the buoy 1 in real time;

[0038] The antifreeze mechanism 10 includes a nozzle 1005. The top of the buoy 1 is provided with a nozzle 1005. The bottom end of the nozzle 1005 is connected to the output end of the spray pump 1002 through the outlet pipe 1004. The input end of the spray pump 1002 is connected to the antifreeze tank 1001 through the inlet pipe 1003.

[0039] The spray pump 1002 can generate strong pressure to extract the antifreeze from the antifreeze tank 1001. The antifreeze tank 1001 serves as a storage container for the antifreeze and reserves sufficient antifreeze so that in a low temperature environment, when the buoy 1 needs to be protected from freezing, the required antifreeze can be provided to the entire antifreeze system in time. The antifreeze in the antifreeze tank 1001 is extracted and sprayed evenly onto the surface of the buoy 1 through the outlet pipe 1004 and the nozzle 1005, forming a layer of antifreeze protective film on the surface of the buoy 1, effectively lowering the freezing point of the surface of the buoy 1 and preventing seawater from freezing on the surface of the buoy 1, thereby ensuring the normal use function of the buoy 1 and the safety and reliability of the entire fan foundation.

[0040] Please refer to the attached Figure 1 -Attached Figure 3 and attached Fig. 9 -Attached Fig.10 The inner side of the plurality of buoys 1 is provided with an interception mechanism 8, the interception mechanism 8 comprises a plurality of fixing plates 801, the fixing plates 801 are respectively connected to the inner side of the buoys 1, the inner side of the fixing plates 801 is provided with a fixing shaft 802, the fixing shaft 802 is connected to a fixing ring 805 through a disassembly assembly, the bottom of the fixing ring 805 is connected to a net-binding bolt 810 through a connecting rod 809, an interception net 811 is provided between the plurality of net-binding bolts 810, and the fixing plates 801 serve as the basic supporting component of the entire interception mechanism 8;

[0041] The interception net 811 is made of a high-strength, corrosion-resistant material with a suitable mesh size, which can effectively block fish and other marine life from swimming near the mounting platform 201, preventing marine life from causing damage such as entanglement and collision to the power generation fan 11 and other auxiliary equipment on the mounting platform 201, and also preventing marine life from attaching and breeding on the surface of the equipment to affect the performance of the equipment such as heat dissipation and operating efficiency;

[0042] The disassembly assembly includes a sliding key 803, which is slidably connected to the middle of the fixed shaft 802, a blocking cap 804 is fixedly connected to the inner end of the fixed shaft 802, a plurality of connecting pins 807 are slidably connected to the fixed ring 805, a baffle 806 is fixedly connected to the inner end of the connecting pin 807, and a fixing spring 808 is arranged between the baffle 806 and the inside of the fixed ring 805;

[0043] The main function of the blocking cap 804 is to limit the inward sliding displacement of the fixing ring 805 during the installation process, ensuring that the fixing ring 805 can be accurately positioned at the appropriate position of the fixing shaft 802. When the baffle plate 806 hits the blocking cap 804, the baffle plate 806 will be stored in the fixing ring 805 under the blocking effect of the blocking cap 804. At this time, the connecting pin 807 will squeeze the fixing spring 808, so that the fixing spring 808 is gradually compressed and stores elastic potential energy. When the fixing ring 805 slides to the middle section of the fixing shaft 802, since the blocking cap 804 no longer has a blocking effect on the baffle plate 806, the fixing spring 808 will release the stored elastic potential energy and push the baffle plate 806 to pop out, thereby stably fixing the interception net 811 on the fixing shaft 802. When disassembly is required, the sliding key 803 can remove the fixing ring 805.

[0044] The shielding assembly 7 includes a plurality of assembly rings 701. The outer side of the mounting platform 201 in the mounting assembly 2 is connected with a plurality of assembly rings 701 by bolts. A shielding net 702 is arranged between the assembly rings 701. A transmission conductor 703 is arranged at the bottom end of the mounting platform 201 in the mounting assembly 2. The shielding net 702 is made of a material with good electromagnetic shielding performance, and its main function is to effectively eliminate most of the electromagnetic interference generated in the power generation process.

[0045] As a key channel for electric energy transmission, the transmission conductor 703 undertakes the important task of safely and efficiently transmitting the electric energy generated by the wind turbine 11 to the power supply station. It has good conductivity and insulation properties, can stably transmit electric energy in a complex marine environment, avoid electric energy loss and leakage during transmission, and ensure the reliability of electric energy supply for the entire offshore wind power system.

[0046] Please refer to the attached Figure 1 -Attached Figure 3 A fixing mechanism 3 is provided on the outward side of multiple buoys 1. The fixing mechanism 3 includes multiple mounting piles 301. The outer top ends of multiple buoys 1 are fixedly connected with mounting piles 301. Anchor chains 302 are provided on the mounting piles 301. The anchor chains 302 pass through mounting rings 303. The mounting rings 303 are fixedly connected to the buoys 1. The mounting piles 301 serve as connecting carriers of the anchor chains 302. The mounting rings 303 are intended to ensure that the anchor chains 302 can evenly disperse the tension to the buoys 1 during the force process, so as to avoid damage to the structure of the buoys 1 caused by local stress concentration. The anchor chains 302 can fix the wind turbine foundation on the sea surface.

[0047] Please refer to the attached Figure 1 -Attached Figure 5The wave energy utilization mechanism 4 includes a plurality of mounting frames 401, which are respectively arranged on the connecting columns 203, and a generator 405 is arranged in the mounting frames 401. A pulley 402 is fixedly connected to the input end of the generator 405, and a transmission belt 404 is arranged on the pulley 402. The top and bottom ends of the vibrating float 5 are respectively connected to the two ends of the transmission belt 404 through connecting ropes 403, and the transmission belt 404 passes through a plurality of steering blocks 406.

[0048] The mounting frame 401 is an important supporting structure for realizing efficient conversion of wave energy into electrical energy. The generator 405 is the core device for converting tidal energy into electrical energy. The pulley 402 is a key component for power transmission, which can effectively receive power from the transmission belt 404 and transmit it to the generator 405.

[0049] The vibrating float 5 is designed according to the principle of wave energy, and its shape and mass distribution are carefully optimized, so that it can produce efficient up and down floating motion under the periodic action of waves;

[0050] The setting of the steering block 406 effectively changes the transmission direction of the transmission belt 404, so that it can adapt to the movement direction of the vibrating float 5, ensuring the smooth transmission of power, and the two ends of the transmission belt 404 are fixedly connected to the connecting rope 403 respectively, thereby realizing the up and down floating movement of the vibrating float 5 to drive the transmission belt 404 to move through the connecting rope 403, and then drive the pulley 402 to rotate, and finally enable the generator 405 to convert wave energy into electrical energy.

[0051] Please refer to the attached Figure 6 -Attached Figure 7 The wave energy utilization mechanism 4 is provided with a vibrating float 5, and the vibrating float 5 is provided with a scraping mechanism 6, the scraping mechanism 6 includes a mounting plate 601, the vibrating float 5 is rotatably connected with the mounting plate 601, a plurality of brushes 603 are provided on the inner side of the mounting plate 601, the top end of the mounting plate 601 is fixed to the end point B of the connecting shaft 602, the top end of the vibrating float 5 is provided with a mounting cabin 604, and a rotating motor 609 is provided in the mounting cabin 604, and the output end of the rotating motor 609 is connected to the end point C of the connecting shaft 602 through a transmission component;

[0052] The brush 603 is made of a soft material with certain toughness and wear resistance, which can effectively contact the surface of the vibrating float 5, and gently scrape off the silt attached to the surface during the rotation process without causing damage to the surface of the vibrating float 5. The connecting shaft 602 is a key component for transmitting power, which transmits the power of the transmission component in the installation cabin 604 to the installation plate 601, so that it can achieve the rotation and scraping action. The installation cabin 604 provides a stable and sealed installation space for the driving components of the scraping mechanism 6, effectively protecting the internal equipment from the erosion of seawater and other adverse effects of the marine environment. The rotary motor 609 serves as the power source of the scraping mechanism 6;

[0053] The transmission assembly includes a sun gear 606, which is fixedly connected to the output end of the rotating motor 609, and is meshed with a planetary gear 607. The outer side of the planetary gear 607 is meshed with a gear ring 608, and the outer side of the gear ring 608 is fixedly connected to the inside of the installation cabin 604. The end point C of the connecting shaft 602 passes through the rotating cover 605 and is connected to the planetary gear 607. The rotating cover 605 is rotationally connected to the installation cabin 604.

[0054] The sun gear 606 serves as the starting component for power input, and effectively transmits the rotational power generated by the rotating motor 609. The sun gear 606 is precisely meshed with the planetary gear 607. Driven by the sun gear 606, the planetary gear 607 rotates around its own axis. At the same time, due to the meshing relationship between it and the ring gear 608, the planetary gear 607 also revolves along the trajectory of the ring gear 608. The rotating cover 605 can not only ensure the smooth rotation of the connecting shaft 602, but also effectively prevent impurities such as seawater from entering the installation cabin 604.

[0055] Working principle: The connecting columns 203 are connected between the multiple groups of buoys 1, and then the crossbeam 202 in the middle connects the mounting platform 201, so that the buoyancy of the buoy 1 can be transmitted to the wind turbine 11 on the mounting platform 201. The mounting platform 201 is provided with a wind power conversion device inside, which can convert wind energy into electrical energy by using the wind turbine 11, and then the electrical energy is transmitted from the transmission wire 703 to the power supply station. The mounting platform 201 is installed with a shielding net 702 through an assembly ring 701. The shielding net 702 can eliminate most of the electromagnetic generated during the power generation process. The fixing ring 805 is slid into the fixing shaft 802. During the sliding process, when the baffle 806 hits the blocking cap 804, the baffle 806 moves toward the fixing ring 805. 05, at this time, the connecting pin 807 squeezes the fixing spring 808, when the fixing ring 805 slides to the middle section of the fixing shaft 802, the fixing spring 808 releases the elastic potential energy, the baffle 806 pops out, and the interception net 811 is fixed to the fixing shaft 802, the fixing ring 805 is connected to the net binding bolt 810 through the connecting rod 809, and then the interception net 811 is tied to the net binding bolt 810, and the interception net 811 covers the bottom of the buoy 1 to prevent fish from swimming near the installation platform 201. When the wind turbine foundation reaches a suitable position, the anchor chain 302 on the installation pile 301 is passed through the installation ring 303 and thrown into the sea. The anchor chain 302 fixes the equipment, and the mounting frame 401 is installed on the beam 202, and the vibrating float. 5 floats up and down in the sea due to the effect of tides, and the connecting rope 403 connects the transmission belt 404 with the vibration float 5. Under the steering of the steering block 406, the up and down floating vibration float 5 makes the transmission belt 404 drive the pulley 402 to rotate back and forth. Under the rotation of the pulley 402, under the conversion effect of the generator 405, the tidal energy is converted into electrical energy, and then the electrical energy is transmitted to the transmission wire 703. When silt such as seaweed is attached to the vibration float 5, the rotating motor 609 in the installation cabin 604 is started, and the rotating motor 609 makes the sun gear 606 rotate. The rotating sun gear 606 is in a meshing relationship, which makes the planetary gear 607 rotate. The rotating line The star gear 607 meshes with the ring gear 608, and then the planetary gear 607 rotates around the track of the ring gear 608. The connecting shaft 602 transmits the movement of the planetary gear 607 to the mounting plate 601. The brush 603 on the mounting plate 601 scrapes off the attachments. When the temperature sensor 903 detects that the temperature is too low, the heating wire 902 is started. The heating wire 902 generates heat after being energized. The heat generated heats up the buoy 1 through the conduction plate 901. The started spray pump 1002 transmits the antifreeze in the antifreeze tank 1001 through the water inlet pipe 1003 and the water outlet pipe 1004. The antifreeze is sprayed from the nozzle 1005 and sprayed onto the buoy 1 to prevent the surface of the buoy 1 from freezing.
