Description

Technical Field

[0001] This invention belongs to the field of offshore wind power generation, and specifically relates to an orbital wing type offshore wind power generation device. Background Technology

[0002] In recent years, to address global warming, countries have unanimously chosen to replace fossil fuels with renewable energy sources such as wind and solar power for electricity generation. Offshore wind power, in particular, has gained popularity among renewable energy sources due to its advantages such as not occupying land space, large wind energy reserves, and stable wind speeds. However, high cost has always been a problem limiting the large-scale development and application of offshore wind power.

[0003] Currently, new energy power generation faces the challenge of cost reduction and efficiency improvement. Wind power generation has limited room for improvement in efficiency, so in order to reduce costs, wind turbines are developing towards larger sizes. The length of a single blade can exceed that of a football field, and some offshore turbines are even taller than 50-story buildings. The base of a standard turbine requires 40 truckloads of concrete. Larger turbines can collect more energy more stably, reducing the cost per kilowatt-hour. However, these massive turbines also significantly increase costs at every stage. From materials to manufacturing, transportation, logistics, construction, and maintenance, dealing with long blades and tall tower structures can severely exceed the budget. Therefore, this invention provides a novel orbital-bladed wind power generation device that is low-cost and easy to install. Summary of the Invention

Detailed Implementation

[0051] The specific technical solution of the present invention will be further described in detail below with reference to specific examples.

[0052] The present invention describes a novel orbital wing type offshore wind power generation device, which mainly consists of a main body outer frame, a magnetic induction power generation system, a braking system, and a blade retraction system.

[0053] The main external frame includes a ring track 1, a support column 2 and a wind speed and direction instrument 3. The ring track 1 includes an upper slide rail 4, a lower slide rail 5 and a magnetic cavity 6.

[0054] The magnetic induction power generation system includes a wind turbine assembly, a sliding system, and a connecting rod 7; wherein, the wind turbine assembly includes blades 8, a connecting column 9, a shorting column 10, a connecting ball 11, and an L-shaped plate 12;

[0055] The sliding system includes a slider 13, an induction coil 32, a spherical groove 14, and a limiting rod 15;

[0056] The braking system includes a hydraulic brake chamber, which includes an induction motor 16, a motor support platform 17, a hydraulic paddle 18, a hydraulic push rod 19, a hydraulic oil tank 20, a hydraulic oil pipeline 21, a hydraulic bladder 22, and a brake pad 23.

[0057] The blade retraction system includes a blade retraction system compartment, which includes an induction motor 24, a motor support platform 25, a motor shaft 26, a spring rope 27, a buckle 1 28, a buckle 29, a fixing column 30, a spring 31, and a slot 33.

[0058] The track-wing offshore wind power generation device designed in this invention is installed in shallow nearshore waters and is fixed by the surrounding support columns 2 of the ring track 1 embedded in the seabed. The device of this invention can be used as a single module power generation equipment for coastal residents, or it can be assembled into a group of "track-wing offshore wind power generation devices" to form power generation modules. Different application methods can be selected according to different application scenarios. The following will introduce the power generation principle of this invention under normal wind speeds and the emergency handling when encountering unconventional wind speeds.

[0059] Under normal wind speeds, the connection method of the power generation structure of the new track-wing offshore wind power generation device is as follows: the blade 8 in the wind turbine of the magnetic induction power generation system is riveted to the connecting column 9 through the L-shaped plate 12. The connecting column 9 is welded to the connecting ball 11 through the shorting column 10. The connecting ball 11 is adapted to the spherical groove 14 on one side of the slider 13 in the sliding system. The induction coil 32 is connected to the other side of the slider 13 through the connecting rod 7. The induction coil 32 is located in the magnetic cavity 6 inside the ring track. Two magnets with opposite magnetic poles are arranged on the upper and lower inner walls of the magnetic cavity 6.

[0060] Principle: Under the influence of the incoming wind direction, the blade 8 first adjusts its direction under the action of the connecting ball 11, and then drives the slider 13 to move along the upper and lower sliding rails on the circular track 1. At this time, the induction coil 32 located inside the magnetic cavity 6, which is connected to the slider 13 through the connecting rod 7, also moves along with it. The direction of the movement is perpendicular to the direction of the magnetic field, cutting the magnetic field lines and generating an induced current, thus realizing the conversion from mechanical energy to electrical energy.

[0061] Furthermore, the power generation device of the present invention can be used in shallow sea areas close to land.

[0062] Furthermore, the circular track 1 is elliptical and is a lightweight track.

[0063] Furthermore, the bottom of the support column 2 in the main external frame is embedded in the seabed, and its bayonet is connected to the annular track 1 by welding;

[0064] The upper slide rail 4 and lower slide rail 5 in the main body's external frame are located on the upper and lower surfaces of the annular track 1, respectively.

[0065] The magnetic cavity 6 in the outer frame is located inside the ring track 1. N poles are arranged on the upper surface of the magnetic cavity 6 and S poles are arranged on the lower surface, forming a magnetic field with the N poles pointing in the direction of the S poles.

[0066] Furthermore, the magnetic induction power generation system includes a wind turbine assembly, a sliding system, and a connecting rod 7. The wind turbine assembly includes blades 8, connecting columns 9, shorting columns 10, connecting balls 11, and an L-shaped plate 12. The blades 8 and connecting columns 9 in the wind turbine assembly are connected by the L-shaped plate 12. The connection method is that the L-shaped plate 12 is fixed with bolts at the positions where it connects to the blades 8 and connecting columns 9, instead of using the traditional welding method, which facilitates the subsequent maintenance of the wind turbine assembly.

[0067] Furthermore, the sliding system in the magnetic induction power generation system includes a slider 13, an induction coil 32, a spherical groove 14, and a limiting rod 15. The slider 13 is composed of upper and lower half sliders. The upper half slider is connected to the upper slide rail 4 through a bayonet, and the lower half slider is connected to the lower slide rail 5 through a bayonet. When the above steps are completed, the upper and lower half sliders are connected together by welding.

[0068] The limiting rod 15 is connected between the two sliders 13 by welding and moves together with the sliders 13. Its function is to prevent the two sliders 13 from colliding.

[0069] Furthermore, the induction coil 32 in the magnetic induction power generation system is located inside the magnetic cavity 6, but does not contact the inner wall of the magnetic cavity 6. During the sliding process of the wind turbine, the direction of motion of the induction coil 32 is perpendicular to the direction of the magnetic field, thereby generating an induced current.

[0070] Furthermore, the magnetic induction power generation system includes a wind blade device, a sliding system and a connecting rod 7, and the connection between them is as follows: the upper half slider and the lower half slider in the slider system each have a half spherical groove, and the spherical groove 14 formed when they are connected together has a larger space than the connecting ball 11 on the short connecting post 10 in the wind blade device.

[0071] When the upper and lower half sliders are connected, they are locked in place by the connecting ball 11. Welding is then used to connect the two. Next, the induction coil 32 is welded to the combined slider 13 via the connecting rod 7. This results in the sliding system moving along the upper and lower tracks when the fan blade device moves, causing the induction coil 32 inside the magnetic cavity 6 to move and cut the magnetic lines of force to generate an induced current.

[0072] Furthermore, the connecting ball 11 on the shorting post 10 in the wind turbine device is embedded in the spherical groove 14 of the slider 13, so that the wind turbine system is connected to the slider system. However, the space of the spherical groove 14 is slightly larger than the volume of the connecting ball 11, so that the wind turbine device has a certain range of rotation and can adjust its direction with the change of wind direction, thereby obtaining higher power generation efficiency.

[0073] In addition, under unconventional wind speeds, the emergency response device structure of the novel track-wing offshore wind power generation device is as follows: the device of this invention involves a braking device and a blade retraction system;

[0074] Furthermore, the braking system includes a hydraulic brake chamber located inside the slider 13 that contacts the slide rail; the hydraulic brake chamber includes an induction motor 16, a motor support platform 17, a hydraulic paddle 18, a hydraulic push rod 19, a hydraulic oil tank 20, a hydraulic oil pipe 21, a hydraulic bladder 22, and a brake pad 23.

[0075] The motor support platform 17 is fixed in the hydraulic brake chamber by welding. The induction motor 16 is fixed on the motor support platform 17 by welding. When the anemometer on the wind speed and direction instrument 3 reaches the rated value, the induction motor 16 in the brake system in the slider 13 passes the position of the anemometer and rotates, causing the hydraulic paddle 18 to push the hydraulic push rod 19 forward.

[0076] The anemometer 3 includes both an anemometer and a wind vane, and is located on the support columns 2 on both sides of the long axis of the elliptical ring track 1. The hydraulic paddle 18 is located on the rotating shaft of the induction motor 16 and moves with the rotating shaft. The hydraulic paddle 18 is not a regular circle, and the edge is not completely equal in length to the center of the hydraulic paddle 18. When the braking system is not working, the hydraulic push rod 19 is located at the shortest distance between the hydraulic paddle 18 and the center of the hydraulic paddle 18.

[0077] One end of the hydraulic push rod 19 is in contact with the hydraulic paddle 18, and the other end is connected to the piston inside the hydraulic oil tank 20.

[0078] The hydraulic oil tank 20 is in a sealed state. The piston moves forward under the action of the hydraulic push rod 19. The hydraulic oil in the hydraulic oil tank 20 is transported to the hydraulic bladder 22 through the hydraulic oil pipeline 21 under the action of the piston. The brake pad 23 is connected to the hydraulic bladder 22 and moves with the rise and fall of the hydraulic bladder 22.

[0079] Furthermore, the hydraulic oil tank 20, hydraulic oil pipeline 21 and hydraulic bladder 22 in the braking system form a completely sealed device. If air enters the system during operation, the presence of air bubbles in the pipeline will prevent the transmission of braking action, which may result in problems such as insensitive braking and longer braking distance.

[0080] In the braking system, each slider 13 is installed (two sets are required for each slider, located at the positions where the upper and lower sliders are connected to the slide rail, respectively).

[0081] Furthermore, the blade retraction system includes a blade retraction system compartment located within the connecting column 9 in the wind turbine assembly. The blade retraction system compartment includes an induction motor 24, a motor support platform 25, a motor shaft 26, a spring rope 27, a buckle 1 28, a buckle 29, a fixing column 30, a spring 31, and a slot 33.

[0082] The second motor support platform 25 is fixedly welded to the blade retraction system compartment. The second induction motor 24 is fixedly connected to the second motor support platform 25. One end of the spring rope 27 is connected to the fixed column 30, and the other end is wrapped around the motor shaft 26.

[0083] The fixing column 30 is located inside the blade 8 of the wind turbine device, one of which is located at the top of the wind turbine device and parallel to the upper surface of the annular track 1, and the other is located at the bottom of the wind turbine device and parallel to the lower surface of the annular track 1.

[0084] When the motor shaft 26 rotates and tightens the spring rope 27, the blade 8 will retract towards the center under the action of the spring rope 27;

[0085] The purpose is to reduce fatigue damage to blade 8 under high wind speeds and avoid the possibility of breakage. One blade retraction system is installed on each blade 8.

[0086] When the wind speed measured by the anemometer on the wind direction and speed meter 3 exceeds the set value, it will transmit a signal to the braking system and the blade retraction system. The induction motor 16 in the braking system drives the hydraulic pawl 18 to rotate, pushing the hydraulic push rod 19 forward. The hydraulic push rod 19 pushes the piston in the hydraulic oil tank 20 forward, causing the hydraulic oil to flow along the pipe to the hydraulic bladder 22. The hydraulic bladder 22 expands due to the entry of hydraulic oil, which also drives the brake pad 23 to move downward, thereby increasing the friction between the slider 13 and the annular track 1, causing the slider 13 to gradually stop sliding. At this time, the induction motor 16 stops rotating and remains stationary. When the wind speed recovers, operation resumes. Simply reverse the induction motor 16 so that the hydraulic oil in the hydraulic bladder 22 returns to the hydraulic oil tank 20 through the hydraulic oil pipe 21. At this time, the brake pad 23 returns to normal, and the structure resumes operation.

[0087] Furthermore, the first buckle 28, the second buckle 29, and the slot 33 in the blade retraction system are adapted and connected during use;

[0088] When the blade 8 is fully extended, the second clip 29 is adapted to the slot 33 to limit the displacement of the fan blade device; when the blade 8 is retracted, the second clip 29 is released, and the first clip 28 is adapted to the slot 33 to limit the displacement of the fan blade device.

[0089] After receiving the signal from the wind direction and speed meter 3, the second induction motor 24 in the blade retraction system starts to rotate, causing the spring rope 27 to gradually become taut from its original length. When the upper and lower parts of the blade 8 are pulled by the spring rope 27, they begin to retract inward. At this time, the second buckle 29 is inserted into its spring chamber under the pull of the spring rope 27, and the upper and lower parts of the blade 8 begin to retract. When the first buckle 28 is inserted into the slot 33, the retraction is completed, and the second induction motor 24 stops rotating.

[0090] When the wind speed returns to normal, the second induction motor 24 starts to reverse. Because the spring rope 27 is taut at this time, it will generate an elastic force to eject the retracted part of the blade 8. When the first buckle 28 disengages, the second buckle 29 engages in the slot 33, completing the extension.

[0091] Furthermore, the number of wind turbine blades is selected based on the main dimensions of different specifications of wind power generation equipment, and the location of the wind turbine blades above the sea surface is also determined by taking into account local environmental and hydrological conditions.

[0092] Therefore, the unique elliptical offshore wind power generation technology adopted in this invention has a simple structure, is easy to transport and install, has good overall stability, a wide range of applications, and its size and cost are significantly reduced compared with traditional horizontal axis wind turbines, making it highly practical.
