Description

Technical Field

[0001] This invention belongs to the technical field of flying wind energy, and particularly relates to a space-omnidirectional adjustable power parachute and flying wind energy generator equipment. Background Technology

[0002] Wind energy, as a renewable and clean energy source, has seen development in recent years. Current tower wind power technology can only utilize wind resources at a height of 0-200 meters above the ground, with an annual equivalent full-load hours of only about 2200 hours for wind farms. Due to its impact on grid system stability, power quality, and dispatch management, many wind farms experience "curtailment," further limiting wind energy utilization. Currently, coal-fired power units still bear the base load, with an annual equivalent load time of 4000-5000 hours after peak shaving considerations. Existing wind power technology is not yet capable of handling the heavy burden of base load.

[0003] Both domestic and international research and development in the field of high-altitude wind energy has been carried out, but an effective technical solution has not yet been formed, especially a land-based wind energy technology that can continuously utilize high-altitude wind energy to do work (such as power generation) under any wind direction.

[0008] In a specific implementation, the outer side of the first active pulley is provided with a toothed structure, which matches the ratchet on the connector; after the first active pulley reaches a preset position, the ratchet moves toward the toothed structure and engages with the toothed structure.

[0009] In a specific embodiment, the limiting mechanism further includes a driving component, which includes a motor and a driving shaft connected to the driving end of the motor; the driving shaft is connected to the connecting component and is used to adjust the position of the connecting component so that the first active pulley is connected to the connecting component.

[0010] In some embodiments, the power umbrella is equipped with an encoder for monitoring the rotation angle and displacement of the power umbrella body.

[0011] In some embodiments, the power umbrella body is provided with a plurality of jet outlets, each of which is located on the umbrella top side away from the power umbrella body, so as to improve the aerodynamic stability of the power umbrella body.

[0012] In a specific implementation, the umbrella body has a hemispherical structure or a square groove structure.

Detailed Implementation

[0019] The present invention will be further described in detail below through preferred embodiments, but the scope of protection of the present invention is not limited thereto.

[0020] An embodiment of the present invention discloses a spatially adjustable power umbrella 1.

[0021] Figure 1 A schematic diagram of the overall structure of a power umbrella that can be adjusted in all directions throughout space. (See diagram below.) Figure 1 As shown, the power parachute 1 includes: a power parachute body 101 and a flight control device 102; the power parachute body 1 is connected to the flight control device 102 via a first traction rope 103 and a second traction rope 104; wherein, the flight control device 102 can also be referred to as a flight control device, which is used to adjust the orientation of the power parachute body 101 when the power parachute is in flight so that it can adapt to different wind directions; Figure 2 This is a partial structural diagram of the flight control device; Figure 3 This is a schematic diagram of the internal structure of a power umbrella that can be adjusted in all directions. Figure 2 and 3As shown, the flight control device 102 includes an inner structure 1021, an outer structure 1022, an active pulley assembly 1023, and a driven pulley assembly 1024. The inner structure 1021 includes a first inner ring 10211 and a second inner ring 10212 arranged side by side and connected to each other by bearings. The outer structure 1022 is located on the outer periphery of the inner structure 1021, and the outer structure 1022 is connected to the inner structure 1021 by bearings. The active pulley assembly 1023 and the driven pulley assembly 1024 are located at the outer structure 1022. The active pulley assembly 1023 includes a first active pulley 10211. 31 and a second active pulley 10232, with a first traction rope 103 wound around the first active pulley 10231 and the second active pulley 10232; the driven pulley group 1024 includes a first driven pulley 10241 and a second driven pulley 10242, with a second traction rope 104 wound around the first driven pulley 10241 and the second driven pulley 10242; the first active pulley 10241 is connected to the first driven pulley 10241 via a first connecting shaft 1025, and the second active pulley 10242 is connected to the second driven pulley 10242 via a second connecting shaft 1026. Through the above structural design, the omnidirectional adjustable power umbrella 1 of the present invention can obtain traction under almost any wind direction, thereby continuously converting wind energy in the air into mechanical work and transmitting it to the ground; furthermore, the traction rope in the power umbrella 1 can greatly counteract torque at multiple locations, thereby greatly reducing the load on the traction motor and achieving low power consumption and lightweight design.

[0022] In one embodiment, the active pulley assembly 1023 and the driven pulley assembly 1024 are located on the outer structure 1022. The first active pulley 10231 and the first driven pulley 10241 are located at the upper end of the outer structure 1022, and the second active pulley 10232 and the second driven pulley 10242 are located at the lower end of the outer structure 1022. Furthermore, the first active pulley 10231 and the second active pulley 10232 are arranged on the same side, and the first driven pulley 10241 and the second driven pulley 10242 are arranged on the other side of the same side. The first connecting shaft 1025 and the second connecting shaft 1026 are located in the space between the outer structure 1022 and the inner structure 1021. The two ends of the first connecting shaft 1025 are respectively connected to the first driving pulley 10241 and the first driven pulley 10241, and the two ends of the second connecting shaft 1026 are respectively connected to the second driving pulley 10242 and the second driven pulley 10242.

[0023] like Figure 3As shown, the flight control device 102 includes a first bearing 1027, an inner ring connecting bearing 1028, and a second bearing 1029. The first bearing 1027 and the second bearing 1029 are respectively located on the upper and lower end faces of the inner layer structure 1021, and are both connected to the outer layer structure 1022. The first inner ring 10211 is connected to the second inner ring 10212 through the inner ring connecting bearing 1028. The first bearing 1027 and the second bearing 1029 allow the outer layer structure 1022 to rotate freely relative to the first inner ring 10211 located at the upper part of the inner layer structure 1021 and the second inner ring 10212 located at the lower part of the inner layer structure 1021. Furthermore, by connecting the first inner ring 10211 and the second inner ring 10212 of the inner layer structure 1021 with the inner ring connecting bearing 1028, the first inner ring 10211 and the second inner ring 10212 rotate relative to each other, reducing motion resistance. Figure 4 This is a schematic diagram of the active pulley system; for example... Figure 4 As shown, a limiting mechanism 10221 is also fixedly provided on the outer structure 1022. The limiting mechanism 10221 is located on one side of the first active pulley 10231. The limiting mechanism 10221 includes a connecting member 10222. After the first active pulley 10231 reaches a preset position, the connecting member 10222 connects to the first active pulley 10231 to fix the position of the first active pulley 10231. According to the detected wind direction, the position of the first active pulley 10231 is adjusted, thereby moving the active pulley group 1023 and the driven pulley group 1024 to a position that allows the umbrella body 101 to adapt to the wind direction. After the first active pulley reaches this position, the limiting mechanism 10221 restricts the movement of the two pulley groups by limiting the first active pulley 10231, so that the umbrella body 101 remains at an angle that adapts to the wind direction.

[0024] Figure 5 This is a schematic diagram of the braking structure at the first active pulley in the active pulley system.

[0025] like Figure 4 and 5 As shown, the outer side of the first active pulley 10231 is provided with a toothed structure, which matches the ratchet 10223 on the connecting member 10222; after the first active pulley 10231 reaches the preset position, the ratchet 10223 moves toward the toothed structure and engages with it; according to Figure 5 In the direction indicated by the middle arrow, the connector 10222 is pushed forward and brought close to the toothed structure of the first active pulley 10231, so that the ratchet 10223 on the connector 10222 engages with the toothed structure, thereby braking the first active pulley 10231.

[0026] Figure 6 This is a schematic diagram of the drive component.

[0027] like Figure 6 As shown, the limiting mechanism 10221 also includes a driving member 10224, which includes a motor 10225 and a drive shaft 10226 connected to the drive end of the motor 10225; the drive shaft 10226 is connected to the connecting member 10222 and is used to adjust the position of the connecting member 10222 so that the first active pulley 10231 is connected to the connecting member 10222. Figure 4 and Figure 5 In the illustrated structure, the drive member 10224 is configured to drive the connecting member 10222 to move. The drive shaft 10226 is threaded and passes through a threaded hole in the connecting member 10222. The drive shaft is rotated by the motor 10225, thereby causing the connecting member 10222 to move towards the first active pulley 10231. In another embodiment, the drive member may also be configured to drive the first active pulley to move.

[0028] like Figure 3 and 4 As shown, the power umbrella 1 is equipped with an encoder 10227, which is used to monitor the rotation angle and displacement of the power umbrella body 101. By setting the encoder 10227 on the pulley, functions such as precise position feedback, speed and acceleration control, motion synchronization and coordination, safety monitoring and fault diagnosis can be realized, thereby adjusting the power umbrella body to an angle that adapts to the wind direction.

[0029] like Figure 1 As shown, the power umbrella body 101 is provided with a number of jet ports 1011, and each jet port 1011 is located on the side away from the top of the umbrella body 101 to improve the aerodynamic stability of the power umbrella body 101; that is, each jet port 1011 is located on the side close to the edge of the power umbrella body 101; this structural design can increase the overall rotational inertia of the power umbrella body 101, and greatly improve the aerodynamic stability of the power umbrella body 101.

[0030] In embodiments of the present invention, the umbrella body 101 can have different shapes, such as a hemispherical structure or a square groove structure.

[0031] like Figure 1 As shown, the umbrella body 101 has a square groove structure; the square groove structure can be composed of a square bottom surface and four inclined surfaces, and the square groove structure is a hollow structure with a large opening and a small bottom surface. Preferably, the square groove structure has eight jet ports 1011, each jet port 1011 symmetrically opened on the inclined surface of the square groove structure along the axis of the square groove structure. More preferably, two jet ports 1011 are provided at the connection end of one inclined surface with other inclined surfaces; adjacent jet ports 1011 are symmetrically arranged along the connecting line between the two inclined surfaces.

[0032] Figure 7A schematic diagram of the overall structure of a power umbrella that can be adjusted in all directions throughout space; such as Figure 7 As shown, the power umbrella body 101 has a hemispherical structure, and the interior of the hemispherical structure is hollow. Preferably, the hemispherical structure is provided with six jet ports 1011, and each jet port 1011 is symmetrically opened along the axis of the hemispherical structure on the top side of the umbrella away from the power umbrella body.

[0033] One embodiment of the present invention discloses a flying wind turbine generator set. Figure 8 A structural schematic diagram of a flying wind turbine generator set; Figure 9 A schematic diagram of the structure of the device that performs work for flight.

[0034] like Figure 8 As shown, the flying wind turbine equipment includes a levitation device 2 and a transmission cable 3. The levitation device 2 is used to lift the flying wind turbine equipment to a predetermined height. The transmission cable 3 is arranged around an upper pulley 4 near the levitation device 2 and a lower pulley 5 near the fixed foundation structure. The flying wind turbine equipment also includes a flying power device 6 fixedly connected to the transmission cable 3 on both sides. The flying power device 6 is configured to fly up and down alternately to drive the transmission cable 3 to reciprocate. The flying power device 6 includes a power umbrella 1 as described above.

[0035] In this embodiment, as Figure 9 As shown, the omnidirectional adjustable power parachute 1 is installed in the flying wind turbine equipment. Driven by wind energy, the power parachute 1 causes the transmission cable 3 connected to the flying power device 6 to move alternately and reciprocally, thereby driving the ground power device 8 to generate electricity. The inner structure 1021 of the flight control device 102 contains a tether cable 7. The flying power device 6 includes the omnidirectional adjustable power parachute 1, with transmission cables 3 fixedly connected to both sides. This allows the flying power device 6 to move relative to the tether cable 7, and its operation is unaffected by changing wind directions, preventing the transmission cable 3 connected to the outer structure 1022 from becoming entangled with the tether cable 7. Simultaneously, it ensures that the power parachute body 101 can rotate freely relative to the inner structure 1021 with the outer structure 1022 under any wind direction conditions.

[0036] In this embodiment, as Figure 9 As shown, the inner structure 1021 of the power umbrella 1 consists of two relatively independent upper and lower parts, ensuring that the transmission cable 3 of the flying wind turbine equipment does not have to overcome the motion resistance caused by the local twisting of the tether cable 7 when it is generating electricity.
