Description

Technical Field

[0001] The present invention belongs to the technical field of wind power generation equipment, in particular to an offshore wind power generation equipment. Background Art

[0002] A wind turbine is an electrical device that converts wind energy into mechanical energy, which drives the rotor to rotate and ultimately outputs alternating current. A wind turbine is generally composed of components such as a wind rotor, a generator, a direction regulator, a tower, a speed limit safety mechanism and an energy storage device. The working principle of a wind turbine is relatively simple. The wind rotor rotates under the action of wind force, and it converts the kinetic energy of the wind into mechanical energy of the wind rotor shaft. The generator rotates and generates electricity driven by the wind rotor shaft. Currently, common wind turbines are land-based, and the installation foundation they use is a fixed foundation. Floating wind turbines change the fixed foundation to a floating foundation, allowing the wind turbine to float on the water, thereby adapting to more installation environments.

[0003] In the current existing technology, most offshore wind power generation equipment uses a floating foundation. Since the floating foundation floats in the sea, the weather conditions at sea are mostly severe, strong winds are very common, and strong winds will cause waves on the sea surface. The floating foundation of the offshore wind power generation equipment is prone to large vertical swings under the action of wind and waves, which in turn causes damage to the wind power generation equipment, which is not conducive to long-term use.

DETAILED DESCRIPTION

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0031] like Figures 1 to 3 As shown, an offshore wind power generation device according to an embodiment of the present invention includes a wind rotor 1, a generator 2 is installed at the end of the wind rotor 1, a support column 3 is fixedly connected to the bottom end of the generator 2, a main buoy 4 is fixedly connected to the bottom end of the support column 3, a plurality of auxiliary buoys 6 are provided on the outside of the main buoy 4, a plurality of connecting rods 5 are fixedly connected between the main buoy 4 and the auxiliary buoy 6, a mooring rope 7 is fixedly connected to the side of the auxiliary buoy 6 away from the main buoy 4, and a pile 8 is installed on the end of the mooring rope 7 away from the auxiliary buoy 6;

[0032] During operation, the conventional floating foundation for wind power generation is prone to significant shaking when encountering strong winds and waves, thereby affecting the stability of the wind turbine. However, with the embodiment of the present invention, before use, it is necessary to first embed the pile 8 on the seabed at the bottom of the installation location, and then assemble the other components in sequence. It should be noted that the assembly work can be completed on shore.

[0033] During actual use, the wind will drive the wind wheel 1 to rotate, and when the wind wheel 1 rotates, the mechanical energy will be transmitted to the generator 2, and the generator 2 will convert it into electrical energy, thereby realizing the foundation of wind power generation; since the main buoy 4 and the auxiliary buoy 6 are connected by multiple connecting rods 5, they form a whole with each other, which improves their overall stability. At the same time, under the action of buoyancy, the mooring rope 7 will also be stretched by the auxiliary buoy 6 to the maximum stress state, and the mooring rope 7 is fixed by the pile 8, and the pile 8 is embedded in the seabed. At this time, the mooring rope 7 can provide a larger pulling force for the auxiliary buoy 6 to limit its shaking amplitude. In this way, when encountering large winds and waves, the embodiment of the present invention can provide higher stability for the support column 3 to reduce the impact of wind and waves on it and improve the service life of the equipment.

[0034] like Figures 4 to 6 As shown, a cavity is opened inside the main buoy 4, an elastic rope 9 is fixed to the top surface of the inner wall of the main buoy 4, and a counterweight block 10 is fixed to the bottom end of the elastic rope 9;

[0035] During operation, when encountering wind and waves, the main buoy 4 will inevitably shake due to the wind and waves. For this reason, a counterweight block 10 is set inside the main buoy 4 and fixed by an elastic rope 9. When the main buoy 4 shakes, the counterweight block 10 will generate a force opposite to the shaking of the main buoy 4 due to inertia lag, thereby offsetting the shaking force of the main buoy 4, reducing the shaking amplitude of the main buoy 4, and then reducing the shaking amplitude of the entire equipment, further improving the stability of the equipment operation.

[0036] like Figures 4 to 7 As shown, a through hole is provided inside the main buoy 4 and on one side of the cavity, and a lifting block 12 is slidably connected to the through hole inside the main buoy 4. A discharge hole adapted to the through hole is provided inside the lifting block 12, and a driving assembly is provided above the lifting block 12 to drive the lifting block 12 to move up and down;

[0037] During operation, when encountering typhoon weather, since the airflow at high places is faster than that at low places, the wind wheel 1 and the generator 2 will be under greater pressure, which may easily lead to overload and damage of the equipment. When the embodiment of the present invention is in use, the driving assembly can be used to drive the lifting block 12 to descend, so that the discharge hole inside the lifting block 12 is aligned with the through hole. At this time, the external water will flow into the cavity inside the main float 4 through the through hole and the discharge hole, so that the buoyancy of the main float 4 is reduced. The reduced buoyancy of the main float 4 can drive the support column 3 to descend, and the descent of the support column 3 can drive the wind turbine 1 to descend. The wheel 1 and the generator 2 descend, so that the influence of wind on the wind wheel 1 and the generator 2 is reduced, and the stability of the equipment is improved; at the same time, since the equipment is lowered as a whole, the influence of wind and waves suffered by them is also reduced synchronously, which further protects the equipment, and when water enters the interior of the main buoy 4, the water flow will cover the counterweight block 10, thereby forming a damping effect on the counterweight block 10, further reducing the shaking amplitude of the main buoy 4; it should be noted that a filter is installed on the surface of the main buoy 4 and outside the through hole to prevent aquatic organisms from being affected and entering the interior of the equipment.

[0038] like Figures 4 to 7 As shown, the driving assembly includes a sliding plug 14 fixed to the top of the lifting block 12, and a return spring 15 is fixed to the top of the sliding plug 14. A vent hole 16 is opened inside the main float 4 and above the return spring 15. The outside of the vent hole 16 is connected to a gas injection assembly, which is used to fill the vent hole 16 with gas;

[0039] During operation, when encountering typhoon weather, the gas injection component operates to fill gas into the vent hole 16, so that the air pressure inside the vent hole 16 increases. Under the action of the air pressure, the sliding plug 14 will stretch the return spring 15 to make it deform and slide. The sliding plug 14 slides to push the lifting block 12 to operate, thereby achieving the effect of starting the lifting block 12.

[0040] like Figures 4 to 7 As shown, the gas injection assembly includes an elastic bladder 11, which is annularly mounted on the inner wall of the cavity of the main float 4. A plurality of gas nozzles 18 are connected to the side of the elastic bladder 11 away from the center of the main float 4. The main float 4 has a plurality of mounting holes 17 adapted to the gas nozzles 18, and the gas nozzles 18 are connected to the mounting holes 17 by threads.

[0041] During operation, when encountering typhoon weather, the swing amplitude of the main float 4 will increase significantly, so the swing amplitude of the counterweight block 10 will also increase at this time. By designing the elastic bag 11, the inner wall of the main float 4 can be protected when the swing amplitude of the counterweight block 10 increases, so as to avoid the counterweight block 10 directly colliding with the inner wall of the main float 4, thereby improving the service life of the equipment. When the swing amplitude of the counterweight block 10 is too large and collides with the elastic bag 11, the gas inside the elastic bag 11 will be squeezed. At this time, the gas inside the elastic bag 11 will be injected into the vent 16 through the air nozzle 18 under the action of pressure, thereby achieving the effect of automatically judging the weather conditions and inflating the vent 16 according to the swing amplitude of the main float 4; it should be noted that an electromagnetic valve is installed inside the mounting hole 17 to prevent the gas from flowing back into the elastic bag 11; and the design of the mounting hole 17 and the air nozzle 18 can facilitate the installation of the elastic bag 11 on the inner wall of the main float 4.

[0042] like Figures 4 to 7 As shown, an electromagnet 13 is fixedly connected inside the main float 4 and below the lifting block 12, and a magnetic material is fixedly connected to the bottom end of the lifting block 12;

[0043] When the lifting block 12 is in operation, it moves downward under the pressure of the air so that the through hole is opposite to the discharge hole. At this time, the lifting block 12 just contacts the electromagnet 13. By installing a sensing unit on the surface of the electromagnet 13, such as an infrared detection device or a pressure monitoring device, a signal can be sent to the control system of the equipment to indicate that the lifting block 12 has moved into place. The water intake per unit time is calculated according to the size of the through hole. In this way, the control system can control the water intake inside the main float 4 by controlling the closing time of the lifting block 12, and thus control the overall descent amplitude of the equipment. When controlling the lifting block 12 to close, the solenoid valve inside the installation hole 17 is first opened. At this time, the gas inside the vent 16 will flow back under the action of air pressure and the reset spring 15. To avoid incomplete reflux, the control circuit of the electromagnet 13 can be opened synchronously at this time, so that its operation produces the same magnetism as the lifting block 12, and the magnetic force exerts a repulsive force on the bottom end of the lifting block 12, pushing the lifting block 12 to reset, thereby achieving the effect of intelligent control of the descent amplitude.

[0044] like Figures 4 to 7 As shown, a water pump 19 is fixed to the bottom surface of the inner wall of the main buoy 4, a limit frame 20 is fixed to the top of the main buoy 4, and a plurality of high-pressure nozzles 21 are fixed to the bottom end of the limit frame 20. The water pump 19 is connected to the high-pressure nozzles 21 through internal pipes;

[0045] During operation, after water enters the interior of the main buoy 4, the equipment needs to float after the wind and waves subside. At this time, the water flow inside the main buoy 4 can be pumped out by the water pump 19, and the pumped water is sprayed out through the high-pressure nozzle 21. The position of the high-pressure nozzle 21 is adjusted so that it is directed towards the surface of the support column 3 and the main buoy 4, so that the sprayed water can clean the surface of the support column 3 and the main buoy 4, remove the aquatic organisms on the surface, thereby reducing the corrosion of the waterproof paint on the surface of the support column 3 and the main buoy 4 by the aquatic organisms, and improving the service life of the equipment.

[0046] It should be noted that when designing the pipeline between the water pump 19 and the high-pressure nozzle 21, the pipeline can be passed through the generator 2, so that the water flow can cool the generator 2 during the flow, thereby improving the efficiency of the equipment; further, in an environment without strong winds and high temperatures, the embodiment of the present invention can also start the electromagnet 13 to generate magnetism opposite to that of the lifting block 12, pulling the lifting block 12 downward, so that the water flows into the main float 4, and is extracted by the water pump 19 and then flows and sprayed out, and the generator 2 is cooled synchronously during the spraying process, thereby having a cooling effect.

[0047] like Figures 4 to 7 As shown, the outer side of the bottom end of the main float 4 is slidably connected to an annular scraper 22, the top of the annular scraper 22 is fixedly connected to a lifting ring 23 through a connecting rod, the top surface of the lifting ring 23 is fixedly connected to an inflatable bag 24, and a plurality of limit rods are connected to the inside of the lifting ring 23, and the top ends of the limit rods are fixedly connected to the limit frame 20; when working, in the process of the main float 4 floating up and down, under the action of the buoyancy of the inflatable bag 24, the lifting ring 23 will float up and down together, and the floating of the lifting ring 23 will drive the annular scraper 22 to move When the annular scraper 22 moves, it can scrape the surface of the main float 4, remove the aquatic organisms on its surface, and reduce the corrosion of the surface waterproof paint by the aquatic organisms. It should be noted that during routine maintenance, the staff can control the buoyancy of the inflatable bag 24 by filling and discharging gas into and out of the inflatable bag 24. When the gas inside the inflatable bag 24 is completely discharged, the lifting ring 23 can slide downward along the main float 4 under the action of gravity to achieve the scraping work, thereby achieving the effect of manually controlling the movement of the lifting ring 23.

[0048] like Figures 8 and 9 As shown, the auxiliary buoy 6 includes a mounting seat 601, a telescopic buoy 602 is fixedly connected to the bottom end of the mounting seat 601, a counterweight seat 603 is fixedly connected to the bottom end of the telescopic buoy 602, and a telescopic assembly is installed inside the mounting seat 601, and the telescopic assembly is used to drive the telescopic buoy 602 to extend and retract;

[0049] During operation, when the main float 4 is injected with water and floats down, the mounting seat 601 also needs to cooperate synchronously to reduce the buoyancy. At this time, the telescopic assembly can drive the telescopic float 602 to contract, reducing the volume of the telescopic float 602 and reducing the buoyancy, thereby achieving the effect of cooperating with the main float 4 to descend.

[0050] like Figures 8 and 9 As shown, the telescopic assembly includes an air tank 604, which is fixed to the inside of the mounting base 601. An air pump 605 is fixed to one side of the air tank 604 near the center of the mounting base 601. An air guide tube 606 is fixed to the bottom end of the air pump 605. The air guide tube 606 is in communication with the telescopic float 602. A plurality of multi-stage telescopic rods 607 are fixed to the inside of the telescopic float 602.

[0051] During operation, in specific use, the air pump 605 operates to suck the gas inside the telescopic float 602 through the air guide tube 606 and transports it to the inside of the gas storage tank 604, so that the pressure inside the telescopic float 602 is reduced, thereby compressing the multi-stage telescopic rod 607 and then shrinking it. When the telescopic float 602 needs to be expanded, the air pump 605 sucks the gas inside the gas storage tank 604 and transports it into the telescopic float 602.

[0052] It should be noted that the components in the embodiments of the present invention all need to be coated with anti-corrosion paint to reduce the erosion effect of seawater.

[0053] Working Principle: Traditional floating wind turbine foundations are prone to significant shaking when encountering strong winds and waves, which in turn affects the stability of the wind turbine. However, with the embodiment of the present invention, before use, it is necessary to first embed piles 8 on the seabed at the bottom of the installation location, and then assemble other components in sequence. It should be noted that the assembly work can be completed onshore.

[0054] During specific use, the wind will drive the wind rotor 1 to rotate. When the wind rotor 1 rotates, the mechanical energy will be transmitted to the generator 2, and the generator 2 will convert it into electrical energy, thereby realizing the foundation of wind power generation; because the main buoy 4 and the auxiliary buoy 6 are connected by multiple connecting rods 5, they form a whole with each other, which improves their overall stability. At the same time, under the action of buoyancy, the mooring rope 7 will also be stretched to the maximum stress state by the auxiliary buoy 6, and the mooring rope 7 is fixed by the pile 8, and the pile 8 is embedded in the seabed. At this time, the mooring rope 7 can provide a large pulling force for the auxiliary buoy 6 to limit its shaking amplitude. In this way, when encountering large winds and waves, the embodiment of the present invention can provide higher stability for the support column 3 to reduce the impact of wind and waves on it, thereby increasing the service life of the equipment;

[0055] When encountering wind and waves, the main buoy 4 will inevitably sway due to the wind and waves. For this reason, a counterweight block 10 is set inside the main buoy 4 and fixed by an elastic rope 9. When the main buoy 4 sways, the counterweight block 10 will generate a force opposite to the swaying of the main buoy 4 due to inertia hysteresis, thereby offsetting the swaying force of the main buoy 4, reducing the swaying amplitude of the main buoy 4, and further reducing the swaying amplitude of the entire equipment, further improving the stability of the equipment operation;

[0056] When encountering typhoon weather, since the airflow at high places is faster than that at low places, the wind wheel 1 and the generator 2 will be subjected to greater pressure, which may easily lead to overload and damage of the equipment. When the embodiment of the present invention is used, the driving assembly can drive the lifting block 12 to descend, so that the discharge hole inside the lifting block 12 is aligned with the through hole. At this time, the external water will flow into the cavity inside the main float 4 through the through hole and the discharge hole, so that the buoyancy of the main float 4 is reduced. The reduced buoyancy of the main float 4 can drive the support column 3 to descend, and the support column 3 descends to drive the wind wheel 1 and the generator 2 descends, so that the wind impact on the wind wheel 1 and the generator 2 is reduced, thereby improving the stability of the equipment. At the same time, as the equipment as a whole descends, the impact of wind and waves suffered by it is also reduced synchronously, further protecting the equipment. When water enters the interior of the main buoy 4, the water flow will cover the counterweight block 10, thereby forming a damping effect on the counterweight block 10, further reducing the swaying amplitude of the main buoy 4. It should be noted that a filter is installed on the surface of the main buoy 4 and outside the through hole to prevent aquatic organisms from being affected and entering the interior of the equipment.

[0057] When encountering typhoon weather, the gas injection assembly operates to fill gas into the vent hole 16, causing the air pressure inside the vent hole 16 to increase. Under the action of the air pressure, the sliding plug 14 stretches the return spring 15 to deform it and then slide. The sliding plug 14 slides to push the lifting block 12 to operate, thereby achieving the effect of starting the lifting block 12;

[0058] When encountering typhoon weather, the swing amplitude of the main buoy 4 will increase significantly, so the swing amplitude of the counterweight 10 will also increase. By designing the elastic bag 11, the inner wall of the main buoy 4 can be protected when the swing amplitude of the counterweight 10 increases, so as to avoid the counterweight 10 directly colliding with the inner wall of the main buoy 4, thereby improving the service life of the equipment. When the swing amplitude of the counterweight 10 is too large and collides with the elastic bag 11, the gas inside the elastic bag 11 will be squeezed. At this time, the gas inside the elastic bag 11 will be injected into the vent 16 through the air nozzle 18 under the action of pressure, thereby achieving the effect of automatically judging the weather conditions and inflating the vent 16 according to the swing amplitude of the main buoy 4; it should be noted that an electromagnetic valve is installed inside the mounting hole 17 to prevent the gas from flowing back into the elastic bag 11; and the design of the mounting hole 17 and the air nozzle 18 can facilitate the installation of the elastic bag 11 on the inner wall of the main buoy 4;

[0059] When the lifting block 12 is moved downward by the air pressure so that the through hole and the discharge hole are opposite to each other, the lifting block 12 just contacts the electromagnet 13. By installing a sensing unit on the surface of the electromagnet 13, such as an infrared detection device or a pressure monitoring device, a signal can be sent to the control system of the equipment at this time, indicating that the lifting block 12 has moved into place. The water intake per unit time is calculated according to the size of the through hole. In this way, the control system can control the water intake inside the main float 4 by controlling the closing time of the lifting block 12, thereby controlling the overall descent amplitude of the equipment. When controlling the lifting block 12 to close, the solenoid valve inside the installation hole 17 is first opened. At this time, the gas inside the vent 16 will flow back under the action of air pressure and the return spring 15. In order to avoid incomplete reflux, the control circuit of the electromagnet 13 can be opened synchronously at this time, so that its operation generates the same magnetic field as the lifting block 12, and a repulsive force is applied to the bottom end of the lifting block 12 through the magnetic force, pushing the lifting block 12 to reset, thereby achieving the effect of intelligent control of the descent amplitude.

[0060] After the main buoy 4 enters the water, the equipment needs to float after the wind and waves subside. At this time, the water flow inside the main buoy 4 can be pumped out by the water pump 19, and the pumped water is sprayed out through the high-pressure nozzle 21. The position of the high-pressure nozzle 21 is adjusted so that it is directed towards the surface of the support column 3 and the main buoy 4, so that the sprayed water can clean the surface of the support column 3 and the main buoy 4, remove the aquatic organisms on the surface, thereby reducing the corrosion of the waterproof paint on the surface of the support column 3 and the main buoy 4 by the aquatic organisms, and improving the service life of the equipment.

[0061] It should be noted that when designing the pipeline between the water pump 19 and the high-pressure nozzle 21, the pipeline can be passed through the generator 2, so that the water flow can cool the generator 2 during the flow process, thereby improving the efficiency of the equipment. Furthermore, in an environment without strong winds and high temperatures, the embodiment of the present invention can also start the electromagnet 13 to generate a magnetic force opposite to that of the lifting block 12, pulling the lifting block 12 downward, so that the water flows into the main buoy 4, and is extracted by the water pump 19 and then flows and sprays out, and the generator 2 is cooled synchronously during the spraying process, thereby achieving a cooling effect.

[0062] During the up and down floating of the main buoy 4, under the action of the buoyancy of the inflatable bag 24, the lifting ring 23 will float up and down together, and the floating of the lifting ring 23 will drive the annular scraper 22 to move. The movement of the annular scraper 22 can scrape the surface of the main buoy 4, remove the aquatic organisms on the surface, and reduce the corrosion of the surface waterproof paint by the aquatic organisms. It should be noted that during routine maintenance, the staff can control the buoyancy of the inflatable bag 24 by filling and discharging gas into and out of the inflatable bag 24. When the gas inside the inflatable bag 24 is completely discharged, the lifting ring 23 can slide downward along the main buoy 4 under the action of gravity to perform the scraping work, thereby achieving the effect of manually controlling the movement of the lifting ring 23.

[0063] When the main buoy 4 is injected with water and floats downward, the mounting seat 601 also needs to cooperate with the buoyancy to reduce. At this time, the telescopic assembly can drive the telescopic bladder 602 to contract, reducing the volume of the telescopic bladder 602 and reducing the buoyancy, thereby achieving the effect of cooperating with the main buoy 4 to descend.

[0064] During actual use, the air pump 605 operates to suck the gas inside the telescopic float 602 through the air guide tube 606 and transports it to the inside of the gas storage tank 604, so that the pressure inside the telescopic float 602 is reduced, thereby compressing the multi-stage telescopic rod 607 and then shrinking it. When the telescopic float 602 needs to be expanded, the air pump 605 sucks the gas inside the gas storage tank 604 and transports it into the telescopic float 602.
