Description

Technical Field

[0001] This invention relates to the field of marine renewable energy utilization technology, specifically to a deep-sea wind and wave combined power generation device. Background Technology

[0002] Ocean energy has broad development prospects, with wind and wave energy being two important resources with significant potential for large-scale development. In recent years, with the gradual development of nearshore wind energy resources, the field has reached a certain level of saturation. The coastal areas available for offshore wind, wave, and ocean current energy development are gradually decreasing. Compared to nearshore areas, deep-sea wind energy resources are more abundant and stable. Therefore, the development of deep-sea wind energy resources based on floating wind turbine technology has become a major trend in global marine renewable energy development. Furthermore, areas rich in wind energy resources usually also possess considerable wave energy resources. Although wave energy power generation technology is still in the research and demonstration stage, the technology of integrating wind and wave energy development based on mature offshore wind turbine technology has attracted widespread attention from scholars both domestically and internationally.

[0003] Currently, offshore wind power foundations mainly fall into two categories: fixed and floating. Fixed foundations include monopile, multipile, gravity, high-pile cap, and jacket foundations. Floating foundations include single-column, tension leg, semi-submersible, and barge foundations. As offshore wind power technology matures, wind farms are gradually expanding from nearshore to deep-sea areas. With increasing water depth, foundation types are also transitioning from fixed to floating. Among floating foundations, semi-submersible floating platforms are gradually becoming the mainstream foundation type for future offshore floating wind farms due to their good stability, wide applicable water depth range, and convenient construction and transportation.

[0004] Currently, the utilization efficiency of marine areas is still relatively low, and there is an urgent need to improve the utilization efficiency of marine energy so that the technology can be more widely promoted and applied. To this end, we propose a deep-sea wind and wave combined power generation device. Summary of the Invention

[0005] The purpose of this invention is to provide a deep-sea wind and wave combined power generation device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a deep-sea wind and wave combined power generation device, comprising a central buoy, a wind turbine shaft coaxially mounted on the top of the central buoy, a plurality of telescopic support rods fixedly connected to the top of the wind turbine shaft, and a wind turbine blade mechanism mounted on the free end of the telescopic support rods. The wind turbine blade mechanism can change shape to adapt to different wind speeds and directions. Under the action of wind, the wind turbine blade mechanism rotates, driving the rotor of the first generator to rotate and generate electrical energy.

[0007] Multiple peripheral combined floating platform mechanisms are installed circumferentially at equal intervals on the side wall of the central pontoon. When the waves rise and fall, the air chamber inside the peripheral combined floating platform mechanism generates airflow, which drives the rotor of the second generator to rotate and generate electricity.

[0008] A bracket is fixedly installed at the bottom of the central pontoon, and a deceleration mechanism is rotatably connected to the bracket. The deceleration mechanism is fixedly connected to the wind turbine shaft. When the wind force is too strong, the deceleration mechanism is deployed to increase its contact area with the seawater, which can increase the resistance of the seawater to the deceleration mechanism, thereby reducing the rotational speed of the wind turbine shaft.

[0009] Furthermore, the first generator is installed inside the central pontoon, and the wind turbine shaft is detachably and fixedly installed with the rotor of the first generator.

[0010] Furthermore, the telescopic support rod is configured as an electric telescopic rod, and there are four telescopic support rods. Every two telescopic support rods are used in pairs. In the same pair, one telescopic support rod is installed at the end of the wind turbine shaft, and the other is installed in the middle of the wind turbine shaft.

[0011] Furthermore, the wind turbine blade mechanism is configured as two sets, which are mirror-symmetrically installed on both sides of the wind turbine shaft. The wind turbine blade mechanism includes multiple blade units, and two adjacent blade units are rotatably connected by a revolute joint. A half gear is fixedly installed on one side of the blade unit, and a driven wheel is rotatably connected to the other side of the blade unit. A first motor is fixedly connected inside the blade unit, and a driving wheel is fixedly installed at the output end of the first motor. The driving wheel and the driven wheel mesh with each other. The rotation of the driving wheel in the first blade unit drives the driven wheel to rotate, which can drive the half gear on the second blade unit to deflect, thereby causing the second blade unit to deflect around the first blade unit.

[0012] Furthermore, the number of peripheral combined floating platform mechanisms is three. Each peripheral combined floating platform mechanism includes a floating chamber. A cylinder is fixedly installed on the top of the floating chamber. A piston is slidably connected inside the cylinder. A sleeve is fixedly installed on the top of the piston. A swing arm is fixedly installed on one side of the sleeve. The swing arm is rotatably connected to the top of the cylinder through a rotating joint. A float is fixedly connected to the free end of the swing arm. The float floats on the sea surface. When the waves rise and fall, the float moves up and down, and the swing arm drives the piston to move inside the cylinder, thereby pressurizing the inside of the cylinder.

[0013] Furthermore, an air chamber is fixedly installed at one end of the floating tank, and the air chamber and the floating tank are interconnected. A rotating wheel is rotatably connected to the top of the air chamber, and the rotating wheel is aligned with the exhaust port of the air chamber. The second generator is installed on both sides of the air chamber, and the rotating wheel is mutually driven with the rotor of the second generator through a transmission component. When the airflow blows the rotating wheel to rotate, it will drive the rotor of the second generator to rotate through the transmission component, thereby realizing power generation.

[0014] Furthermore, the transmission assembly includes a first bevel gear fixed at both ends of the rotor and a second bevel gear fixed on the rotor of the second generator, wherein the first bevel gear and the second bevel gear mesh with each other.

[0015] Furthermore, both the floating chamber and the air chamber are hollow cavities, and the end of the floating chamber away from the air chamber is provided with an opening. A pressure relief port is provided between the cylinder and the air chamber, and a protective door is installed on the top of the pressure relief port. The protective door is used to open or close the pressure relief port.

[0016] Furthermore, the deceleration mechanism includes a deceleration cylinder rotatably connected to the bracket via a bearing, and both sides of the deceleration cylinder are provided with strip-shaped openings;

[0017] A second motor is fixedly installed on the top of the reduction cylinder. A drive wheel is fixedly installed through the output end of the second motor through the reduction cylinder. A reduction plate is meshed with both sides of the drive wheel. The reduction plate is slidably connected inside the reduction cylinder and is adapted to the strip opening.

[0018] The top of the reduction gear cylinder is fixed to a storage cylinder via a connecting rod. The second motor is located inside the storage cylinder, and the top of the storage cylinder is fixedly connected to the wind turbine shaft.

[0019] Furthermore, a rack that meshes with the drive wheel is fixedly installed on the side wall of the speed reduction plate. When the drive wheel rotates, the rack can simultaneously drive the speed reduction plates on both sides to move outward or inward.

[0020] This invention has at least the following beneficial effects:

[0021] 1. This invention combines wind power generation with wave power generation, which can supplement wind power generation when wind speed is low and wind power is insufficient, and vice versa. This smooths the output of power generation, improves the overall stability and reliability of the power generation system, and reduces problems such as power outages or equipment idleness caused by fluctuations in a single energy source. Furthermore, by combining wind power generation and wave power generation, multiple energy sources can be developed and utilized simultaneously in a limited marine space, making full use of marine space resources, improving the utilization efficiency of marine space, and providing an efficient way for marine energy utilization.

[0022] 2. This invention modularizes the wind turbine blade mechanism into independent blade units. Under different wind conditions, the first motor drives the drive wheel and driven wheel to rotate, thereby adjusting the relative position between multiple blade units. This allows the shape of the entire wind turbine blade mechanism to be adjusted according to different wind speeds and directions, maximizing the capture of wind energy and converting it into mechanical energy, thereby improving power generation efficiency.

[0023] 3. This invention, through the coordinated arrangement of structures such as cylinders, pistons, swing arms, and floats, can convert the energy generated by the up-and-down movement of ocean waves into electrical energy, thereby improving the utilization efficiency of wave energy.

[0024] 4. The present invention installs an underwater deceleration mechanism at the lower part of the central buoy and connects it to the upper wind-powered shaft. In extreme wind conditions, the deceleration plate can extend to increase the resistance of seawater to the deceleration mechanism, thereby reducing the rotational speed of the wind-powered shaft and protecting the equipment to operate safely under harsh conditions such as strong winds.

[0025] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0034] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0035] Example 1:

[0036] Please see Figures 1-6 The present invention provides a technical solution: a deep-sea wind and wave combined power generation device, including a central float 1, a wind turbine shaft 2 coaxially mounted on the top of the central float 1, a plurality of telescopic support rods 3 fixedly connected to the top of the wind turbine shaft 2, and a wind turbine blade mechanism 4 mounted on the free end of the telescopic support rods 3. The wind turbine blade mechanism 4 can change shape to adapt to different wind speeds and directions. The wind turbine blade mechanism 4 rotates under the action of wind, driving the rotor of the first generator to rotate and generate electrical energy.

[0037] Multiple peripheral combined floating platform mechanisms 5 are installed circumferentially at equal intervals on the side wall of the central float 1. When the waves rise and fall, the air chamber inside the peripheral combined floating platform mechanism 5 generates airflow to drive the rotor of the second generator to rotate and generate electrical energy.

[0038] A support 6 is fixedly installed at the bottom of the central pontoon 1, and a deceleration mechanism 7 is rotatably connected to the support 6. The deceleration mechanism 7 is fixedly connected to the wind turbine shaft 2. When the wind force is too strong, the deceleration mechanism 7 is deployed to increase its contact area with the seawater, which can increase the resistance of the seawater to the deceleration mechanism 7, thereby reducing the rotation speed of the wind turbine shaft 2.

[0039] Regarding the technical solution of this embodiment, the first generator is installed inside the central float 1, and the wind turbine shaft 2 is detachably fixed to the rotor (rotating body) of the first generator. The first generator is configured as a small wind turbine, specifically a permanent magnet AC generator.

[0040] In this embodiment, the telescopic support rod 3 is an electrically operated telescopic rod, and there are four telescopic support rods 3 in total. Each pair of telescopic support rods 3 is used in combination. One of the two telescopic support rods 3 in the same group is installed at the end of the wind turbine shaft 2, and the other is installed in the middle of the wind turbine shaft 2. The telescopic support rods 3 can provide effective support for the wind turbine blade mechanism 4, making the wind turbine blade mechanism 4 more stable during rotation, reducing the vibration and sway of the wind turbine blade mechanism 4, and also adjusting the distance between the wind turbine blade mechanism 4 and the wind turbine shaft 2. At low wind speeds, the distance between the wind turbine blade mechanism 4 and the wind turbine shaft 2 can be appropriately increased to expand the sweeping area of ​​the blades, so that more wind energy can be captured and converted into mechanical energy, thereby improving power generation efficiency. Conversely, at high wind speeds, the distance can be reduced to avoid damage to the wind turbine blade mechanism 4 due to excessive wind force, while also maintaining good power generation performance.

[0041] Regarding the technical solution of this embodiment, the wind turbine blade mechanism 4 is configured as two sets, and the two sets of wind turbine blade mechanisms 4 are installed in a mirror symmetrical manner on both sides of the wind turbine shaft 2. The wind turbine blade mechanism 4 includes multiple blade units 41. Two adjacent blade units 41 are rotatably connected through a revolute joint. A half gear 42 is fixedly installed on one side of the blade unit 41, and a driven wheel 43 is rotatably connected to the other side of the blade unit 41. A first motor 44 is fixedly connected inside the blade unit 41, and a driving wheel 45 is fixedly installed at the output end of the first motor 44. The driving wheel 45 and the driven wheel 43 mesh with each other. The rotation of the driving wheel 45 in the first blade unit 41 drives the driven wheel 43 to rotate, which can drive the half gear 42 on the second blade unit 41 to deflect, thereby causing the second blade unit 41 to deflect around the first blade unit 41.

[0042] It should be noted that the overall cross-section of the single wind turbine blade mechanism 4 is elliptical, and the multiple blade units 41 are set as elongated strips. The blade unit 41 has a cavity inside. One of the blade units 41 is fixedly connected to the telescopic support rod 3 to achieve stable support. When it is necessary to adjust the shape of the wind turbine blade mechanism 4, the first motor 44 is started to drive the drive wheel 45 to rotate, and through the driven wheel 43, it drives the half gear 42 to rotate, so that the second blade unit 41 deflects around the first blade unit 41, thereby adjusting the deflection angle between the two adjacent blade units 41. Similarly, by controlling the rotation of the first motor 44 inside the multiple blade units 41, the relative position between the multiple blade units 41 can be adjusted, thereby adjusting the shape of the entire wind turbine blade mechanism 4 according to different wind speeds and directions.

[0043] It should be further explained when necessary that the half gear 42 is installed on the outer wall of the blade unit 41, and the driving wheel 45 is located inside the blade unit 41, so it will not cause motion interference.

[0044] Specifically, the distribution and flow characteristics of wind energy vary under different wind speeds and directions. By adjusting the deflection angle between the blade units 41, the shape and windward area of ​​the wind turbine blade mechanism 4 can be changed, enabling the wind turbine blade mechanism 4 to accurately face the wind under various complex wind conditions, capture wind energy to the maximum extent and convert it into mechanical energy, thereby improving power generation efficiency. Furthermore, when encountering extreme wind speeds or severe weather such as typhoons, the wind turbine blade mechanism 4 can be adjusted to a more compact shape, reducing the wind-receiving area and reducing the force of wind on the wind turbine blade mechanism 4, thereby effectively protecting the equipment from damage and improving its wind resistance and survivability in harsh environments.

[0045] Regarding the technical solution of this embodiment, the number of peripheral combined floating platform mechanisms 5 is three. The peripheral combined floating platform mechanism 5 includes a floating tank 51. A cylinder 52 is fixedly installed on the top of the floating tank 51. The cylinder 52 is fixedly installed on the side wall of the central floating cylinder 1 through a connecting rod. A piston 53 is slidably connected inside the cylinder 52. A sleeve 54 is fixedly installed on the top of the piston 53. A swing arm 55 is fixedly installed on one side of the sleeve 54. The swing arm 55 is rotatably connected to the top of the cylinder 52 through a rotating joint. A float 56 is fixedly connected to the free end of the swing arm 55. The float 56 floats on the sea surface. When the waves rise and fall, the float 56 will move up and down. The swing arm 55 will drive the piston 53 to move inside the cylinder 52, thereby pressurizing the inside of the cylinder 52.

[0046] In this embodiment, an air chamber 57 is fixedly installed at one end of the floating tank 51. The air chamber 57 and the floating tank 51 are interconnected. A rotating wheel 58 is rotatably connected to the top of the air chamber 57. The rotating wheel 58 is aligned with the exhaust port 59 of the air chamber 57. The second generator is installed on both sides of the air chamber 57. The rotating wheel 58 is driven by the rotor of the second generator through the transmission assembly 8. A pressure relief port 510 is provided between the cylinder 52 and the air chamber 57. A protective door 511 is installed on the top of the pressure relief port 510. The protective door 511 is used to open or close the pressure relief port 510. When the internal pressure of the cylinder 52 reaches the threshold, the protective door 511 is opened. The high-pressure airflow inside the cylinder 52 will be quickly discharged outward through the air chamber 57. When the high-pressure airflow blows the rotating wheel 58 to rotate, it will drive the rotor of the second generator to rotate through the transmission assembly 8, thereby realizing power generation.

[0047] It should be noted that the protective door 511 can be opened or closed by a door opener. A door opener is an electromechanical drive device composed of a motor, a speed change mechanism, and a clutch device. It is mainly used for the electric opening and closing control of various types of doors and belongs to the category of electromechanical products. The inner wall of the protective door 511 is equipped with a pressure sensor. When the set pressure threshold is reached, the door opener is activated to drive the protective door 511 to open. In this embodiment, the opening and closing method of the protective door 511 is not limited to the door opener. It can also be achieved by an electric switch lock. When the electric switch lock is unlocked, the protective door 511 will open under pressure. When the air pressure in the cylinder 52 decreases to be consistent with the external atmospheric pressure, the protective door 511 will automatically fall and close under gravity. At this time, closing the electric switch lock can lock the protective door 511.

[0048] Regarding the technical solution of this embodiment, the transmission component 8 includes a first bevel gear 81 fixed at both ends of the rotating wheel 58 and a second bevel gear 82 fixed on the rotor of the second generator. The first bevel gear 81 and the second bevel gear 82 mesh with each other, and multiple guide vanes are evenly installed on the outer side of the rotating wheel 58. When the airflow blows the guide vanes, it will drive the rotating wheel 58 to rotate, thereby causing the first bevel gear 81 to rotate. The rotation of the second bevel gear 82 will drive the second generator to generate electricity. It should be noted that the design of the guide vanes can increase the contact area between the rotating wheel 58 and the airflow, so that the airflow can more effectively drive the rotating wheel 58 to rotate, thereby converting the kinetic energy of the airflow into mechanical energy for power generation, further improving the utilization rate of airflow energy. The bevel gear transmission has high meshing accuracy and stability, which can ensure smooth and reliable power transmission between the rotating wheel 58 and the generator, reduce vibration and impact during the transmission process, and improve the operational stability of the equipment.

[0049] In this embodiment, both the float 51 and the air chamber 57 are hollow cavities, and the end of the float 51 away from the air chamber 57 has an opening. When the waves rise and fall, and the float 51 moves upward with the waves or changes shape, causing its internal volume to decrease, the gas inside the float 51 is compressed, and the air pressure increases. Conversely, when the float 51 moves downward with the waves or changes shape, causing its internal volume to increase, the gas inside the float 51 is expanded, and the air pressure decreases. When the air pressure inside the float 51 changes, the gas will flow from the high-pressure area to the low-pressure area to balance the air pressure in the system. This gas flow forms an airflow. The airflow blown into the air chamber 57 can drive the rotor 58 to rotate, and then drive the second generator to generate electricity through the transmission component 8.

[0050] It should be noted that the specific type of the second generator is not limited. As long as it is a device that can drive the rotor (rotating body) to rotate and convert mechanical energy into electrical energy, it can be used. The first generator and the second generator are existing devices and will not be described in detail here.

[0051] Regarding the technical solution of this embodiment, the deceleration mechanism 7 includes a deceleration cylinder 71 rotatably connected to the bracket 6 via a bearing. Both sides of the deceleration cylinder 71 are provided with strip-shaped openings 72. This design makes the structure of the deceleration mechanism 7 more compact, reduces space occupation, and facilitates integration and assembly with other components.

[0052] A second motor 73 is fixedly installed on the top of the reduction cylinder 71. The output end of the second motor 73 passes through the reduction cylinder 71 and is fixedly installed with a drive wheel 74. Both sides of the drive wheel 74 are meshed with a reduction plate 75. The reduction plate 75 is slidably connected inside the reduction cylinder 71 and is adapted to the strip opening 72.

[0053] The top of the reduction cylinder 71 is fixed with a storage cylinder 76 via a connecting rod. The second motor 73 is located inside the storage cylinder 76. The top of the storage cylinder 76 is fixedly connected to the wind turbine shaft 2.

[0054] Regarding the technical solution of this embodiment, a rack 77 that meshes with the drive wheel 74 is fixedly installed on the side wall of the speed reduction plate 75. When the drive wheel 74 rotates, the rack 77 can simultaneously drive the speed reduction plates 75 on both sides to move outward or inward. When the speed reduction plates 75 on both sides extend outward at the same time, the force-bearing area of ​​the entire speed reduction mechanism 7 with the seawater can be controlled, thereby increasing the resistance of the seawater to the speed reduction mechanism 7, thereby reducing the rotational speed of the wind turbine shaft 2, protecting the equipment to operate safely under harsh conditions such as strong winds. Moreover, this synchronous control method can ensure that the force on both sides of the speed reduction cylinder 71 is uniform, avoiding problems such as twisting, deformation or jamming of the speed reduction cylinder 71 caused by asynchronous movement of the speed reduction plates 75 on both sides, effectively improving the stability and reliability of the speed reduction mechanism 7. At the same time, the rack 77 transmission can be infinitely adjusted according to actual needs, that is, the moving distance of the speed reduction plate 75 can be continuously adjusted according to the rotation angle of the drive wheel 74, providing a wider adjustment range for the wind turbine control system and better meeting the operating requirements under various complex working conditions.

[0055] It should be noted that the device is also equipped with a battery for storing electrical energy, but this embodiment does not impose specific limitations on it.

[0056] Example 2:

[0057] Compared with Example 1, the fundamental difference of Example 2 is that the transmission component 8 includes a first end face gear fixedly connected to both ends of the rotating wheel 58 and a second end face gear fixed on the rotor of the second generator. The first end face gear and the second end face gear mesh with each other and can transmit power to each other. When the airflow blows the guide vane, it will drive the rotating wheel 58 to rotate, thereby causing the first end face gear to rotate. The rotation of the second end face gear can drive the second generator to generate electricity.

[0058] The operating principle and process of this invention: When power generation is required, the wind turbine blade mechanism 4 is rotated by the sea breeze, which in turn drives the wind turbine shaft 2 to rotate, thereby driving the first generator rotor to rotate and generate electricity. During wind power generation, the telescopic support rod 3 provides effective support for the wind turbine blade mechanism 4, making the wind turbine blade mechanism 4 more stable during rotation, reducing vibration and swaying of the wind turbine blade mechanism 4, and also adjusting the distance between the wind turbine blade mechanism 4 and the wind turbine shaft 2. At low wind speeds, the distance between the wind turbine blade mechanism 4 and the wind turbine shaft 2 can be appropriately increased to expand the sweeping area of ​​the blades, allowing more wind energy to be captured and converted into mechanical energy, thereby improving power generation efficiency. Conversely, During high wind speeds, the distance is reduced to prevent damage to the wind turbine blade mechanism 4 due to excessive wind force, while maintaining good power generation performance. At the same time, by starting the first motor 44, the driving wheel 45 is driven to rotate, and the driven wheel 43 drives the half gear 42 to rotate, so that the second blade unit 41 deflects around the first blade unit 41, thereby adjusting the deflection angle between two adjacent blade units 41. Similarly, by controlling the rotation of the first motor 44 inside multiple blade units 41, the relative position between multiple blade units 41 can be adjusted, thereby adjusting the shape of the entire wind turbine blade mechanism 4 according to different wind speeds and directions, maximizing the capture of wind energy and converting it into mechanical energy, thereby improving power generation efficiency.

[0059] When encountering severe weather, the second motor 73 is started to drive the drive wheel 74 to rotate. When the drive wheel 74 rotates, the rack 77 can simultaneously drive the speed reduction plates 75 on both sides to move outward or inward. When the speed reduction plates 75 on both sides extend outward at the same time, the force-bearing area between the entire speed reduction mechanism 7 and the seawater can be increased, thereby increasing the resistance of the seawater to the speed reduction mechanism 7, thereby reducing the speed of the wind turbine shaft 2 and protecting the equipment to operate safely under severe conditions such as strong winds.

[0060] When it is necessary to generate electricity using ocean waves, the up-and-down movement of the waves will cause the float 56 to move up and down, and through the swing arm 55, it will drive the piston 53 to move inside the cylinder 52, thereby pressurizing the inside of the cylinder 52. When the internal pressure of the cylinder 52 reaches the threshold, the protective door 511 will be opened, and the high-pressure airflow inside the cylinder 52 will be quickly discharged outward through the air chamber 57. When the high-pressure airflow blows the rotor 58 to rotate, it will drive the rotor of the second generator to rotate through the transmission component 8, thereby generating electricity. When the waves rise and fall, the float 51 moves upward with the waves or changes shape, causing the internal volume to decrease, the gas inside the float 51 is compressed and the air pressure increases. When the float 51 moves downward with the waves or changes shape, causing the internal volume to increase, the gas inside the float 51 is expanded and the air pressure decreases. At this time, the air pressure change inside the float 51 will also form an airflow. The airflow blows into the air chamber 57, which can drive the rotor 58 to rotate, and then drive the second generator to generate electricity through the transmission component 8.

The float (56) floats on the sea surface. When the waves rise and fall, the float (56) will move up and down. The swing arm (55) will drive the piston (53) to move inside the cylinder (52) to achieve pressurization inside the cylinder (52). An air chamber (57) is fixedly installed at one end of the floating tank (51). The air chamber (57) and the floating tank (51) are interconnected. A rotating wheel (58) is rotatably connected to the top of the air chamber (57). The rotating wheel (58) is aligned with the exhaust port (59) of the air chamber (57). The second generator is installed on both sides of the air chamber (57). The rotating wheel (58) is driven by the rotor of the second generator through the transmission assembly (8). When the airflow blows the rotating wheel (58) to rotate, it will drive the rotor of the second generator to rotate through the transmission assembly (8), thereby generating electricity. The floating chamber (51) and the air chamber (57) are both hollow cavities. The floating chamber (51) has an opening at the end away from the air chamber (57). A pressure relief port (510) is provided between the cylinder (52) and the air chamber (57). A protective door (511) is installed on the top of the pressure relief port (510). The protective door (511) is used to open or close the pressure relief port (510). The deceleration mechanism (7) includes a deceleration cylinder (71) rotatably connected to the bracket (6) via a bearing, and both sides of the deceleration cylinder (71) are provided with strip-shaped openings (72); A second motor (73) is fixedly installed on the top of the reduction cylinder (71).
