Description

Technical Field

[0001] The present invention relates to the technical field of aerial wind power generation, and more particularly to a flying wing floating integrated layout tethered aerostat type high-altitude wind power generation system. Background Art

[0002] Wind energy is a renewable, clean natural resource. The wind energy stored in the sky is more than 100 times the total energy demand of human society. The wind direction is stable in the altitude range of 1km to 15km, and the higher the altitude, the greater the wind energy density (for every 1m increase in altitude, the wind energy density increases by 0.25 to 0.37W / m 2 ), the better the stability, especially in the high-altitude jet stream area of ​​8km to 12km, the wind speed reaches 30m / s to 50m / s throughout the year (for every doubling of wind speed, the wind energy density increases by 7 times), and the duration, stability and quality of wind power generation are better. High-altitude wind energy is a clean energy with good development prospects.

[0003] At present, there are three main technical approaches to the development and utilization of high-altitude wind energy: tethered kite-type technology system (including paragliders and parachute-ladder combinations), tethered aircraft-type technology system (including airborne power generation and ground power generation) and tethered aerostat-type technology system (including power generation load pods and power generation load and capsule integration). Among them, the tethered kite-type technology system and the tethered aircraft-type technology system basically operate below 1km altitude (wind energy density 500W / m 2 Below 3km altitude actually belongs to the low-altitude category), with inherent disadvantages of technical routes such as difficulty in safe and reliable release and recovery, complex control (easy to fall out of control), short continuous hovering time, weak carrying capacity (flight altitude is very limited, single-machine power generation capacity is only hundreds of kW), etc., which can only use unstable low-altitude wind energy resources and the annual available power generation time is short (about 2200h). However, the air density at high altitude is moderate and the buoyancy efficiency is high (net buoyancy of 0.34kg to 0.77kg per cubic meter of volume), which is particularly suitable for the tethered airship technology system to use static buoyancy to safely and stably launch and recover and maintain (it can be easily achieved by dragging the tethering cable by the ground winch), long-term stable hovering and simple control (basically no active flight control is required), and huge potential for carrying capacity. The natural advantages of the technical route fully develop and utilize the abundant wind energy resources at high altitude (especially the jet stream area at an altitude of 10,000 meters, where uninterrupted and stable power generation can last up to the whole year).

[0004] The flying wing floating integrated layout tethered airship high-altitude wind power generation system utilizes the combination of dynamic lift and static buoyancy to produce a larger load-bearing capacity while reducing its own volume, achieving high-altitude low-cost and high-power wind power generation, and transmitting electricity to the ground through tethered cables.

[0005] However, there are relatively few tethered airship wind power generation technologies with integrated flying wing floating layout, and all of them have technical problems. For example, the core of the invention patent of application No. 200710304161.X, with the name of "Invention of High-altitude Wind Power Generation Equipment Suspended by Balloon", explains that the tethered airship lifts the wind power generation equipment into the air to generate electricity. The front part of the airship has a large horizontal wing auxiliary group to provide dynamic lift and the tail is designed with a smaller tail. The lift generated by the horizontal wing causes a large unstable pitching moment, and the small tail area cannot provide sufficient stable restoring moment, and the overall aerodynamic posture stability cannot be achieved. Another example is the invention patent of application No. 201880024606.5, with the name of "Invention of High-altitude Wind Power Station Tethered to the Ground", which explains the structural form of the flying wing, with the surrounding Using a thin layer of airbags to provide buoyancy (filled with helium, the buoyancy volume is small, and the static buoyancy is very limited) is essentially a tethered aircraft technology, which has the inherent disadvantages of tethered aircraft. The core of the invention patent with application number 201610326323.9 and the patent name is a high-altitude hot wing boat wind power generation system. The semi-rigid hot wing boat with wings is supported by a rigid skeleton and wrapped with flexible airbag materials on the outside (filled with air inside). In the early stage, the ground power is supplied to heat the air through multiple combustion furnaces to provide static buoyancy, and drive the wind wheel blades to rotate in the opposite direction to provide power for liftoff. The system is complex to control and has too much weight. Once the power supply system fails, buoyancy cannot be generated and the system is prone to falling and damage. It is suitable for low altitudes of 500m to 800m.

[0006] In addition, the existing technology of the flying wing floating integrated layout tethered airship high-altitude wind power generation system has the following three common problems to be solved in actual engineering applications, in addition to the existing system aerodynamic stability, load-bearing capacity and flight altitude insufficiency:

[0007] 1) Adaptability to complex high-altitude environments has not been considered

[0008] Complex high-altitude environmental factors include day and night temperature changes (caused by direct sunlight, cloud scattering, etc. during the day, and ground infrared radiation at night; requiring the system airbag to expand safely due to heat during the day and overpressure, and to contract due to cold at night to maintain buoyancy and not drop in height), long-term strong winds and short-term gusts or shear winds (requiring system structural safety and high wind resistance), rain / snow / icing / lightning (requiring the system to be free of water, snow accumulation, anti-icing, and anti-lightning), short-term cold clouds / cold currents (requiring the system to maintain buoyancy and not drop in height), seasonal bird migration safety ecological environment (requiring the system to have the ability to detect birds and automatically drive them away), and civil aviation route safety transportation environment (requiring the system to have the ability to automatically respond to air traffic control services). These are issues that must be considered and solved for the tethered airship high-altitude wind power generation system as a friendly new energy power station infrastructure (20-year design life) in the future, and are the basic requirements for the engineering and practical application of the technical system;

[0009] 2) Long-term stable power generation in the air has not yet been solved

[0010] The abundant wind energy resources at high altitudes have provided objective environmental conditions for stable wind power generation. The problem of long-term airborne residence of tethered airships (carrier platforms, wind turbine generator technology is relatively mature) has become a key technical shortcoming, involving three aspects: First, the existing technologies all use high-pressure airbags (filled with helium) to provide the required static buoyancy and maintain aerodynamic shape stiffness. In actual applications, due to the alternating temperature between day and night at high altitudes, the helium inside the airbag is cooled at night and requires low pressure to maintain its shape (maintaining buoyancy, but with low stiffness), and is heated during the day to generate high pressure (several thousand Pa), which puts heavy pressure on lightweight airbags. The material strength requirements are high, the difficulty is high, and the cost is high; secondly, it is limited by the leakage loss of helium in the airbag (the leakage mass speed is proportional to the square root of the product of the atmospheric pressure at the altitude and the pressure difference between the inside and outside of the airbag). Due to the high atmospheric pressure at high altitude (tens of kilopascals) coupled with the high pressure of the airbag, helium leaks quickly (large amounts of helium demand online replenishment is not feasible), resulting in a sojourn time of only a few months (a big gap from the 20-year sojourn life); finally, the long-term sojourn has a weak control of the adaptive environment (passive control, no complex manipulation required), and is unmanned;

[0011] 3) There is still a gap between low cost and autonomous control

[0012] Lightweight, high-strength airbag materials and helium are the main cost sources of tethered airship high-altitude wind power generation systems, accounting for about 70%. At present, if the existing technology is adapted to the complex high-altitude environment, its high-pressure airbag has high requirements for light weight (low surface density), high strength, air tightness, rubbing resistance, aging resistance and other properties, which is technically difficult and costly (generally up to 700 yuan / linear meter); while the price of helium in my country is expensive, in short supply, and the price remains high.

[0013] Therefore, providing a flying wing floating integrated layout tethered airship type high-altitude wind power generation system is a problem that technical personnel in this field urgently need to solve. Summary of the invention

[0014] In view of this, the present invention provides a flying wing buoyancy integrated layout tethered airship type high-altitude wind power generation system to solve the problems of insufficient system aerodynamic stability, load-bearing capacity and flight altitude in the prior art, as well as the problems of adaptability to complex high-altitude environments, long-term stable power generation, low cost and autonomous control in actual engineering applications to solve the technical deficiencies.

[0023] Furthermore, the surfaces of the lightweight and high-strength composite material component in contact with the outer skin and the buoyancy airbag are coated with a low absorption ratio coating or a total reflection coating or are covered with an aluminum film.

[0024] Furthermore, the supporting structure includes multiple connecting support trusses and multiple supporting hoisting trusses, and multiple wind turbines are connected through the multiple connecting support trusses; the connection points of two adjacent connecting support trusses are connected to the bottom of the corresponding cross-sectional wing-shaped truss structure through the supporting hoisting truss; and multiple cameras and vibration measuring devices are installed on the supporting hoisting truss structure.

[0030] It can be seen that the present invention provides a flying wing floating integrated layout tethered aerostat type high-altitude wind power generation system. Compared with the prior art, the present invention has the following beneficial effects:

[0031] 1) The outer skin, wing-shaped thin-walled load-bearing truss structure and multiple buoyancy airbags constructed in this scheme form a rigid-flexible hybrid stable load-bearing structure system, which utilizes the combination of dynamic lift and static buoyancy to produce a large load-bearing capacity while reducing its own volume. The technical route has high scalability, and the power generation capacity of a single machine can reach several megawatts to tens of megawatts, which can efficiently develop and utilize high-altitude wind energy (especially the jet stream area at an altitude of 10,000 meters).

[0032] 2) It can safely resist long-term strong winds and short-term gusts or shear winds without losing stability. A stable physical gap channel (filled with air) is established between the internal buoyancy airbag and the external skin through a thin-walled load-bearing truss structure of a flying wing configuration, which can keep the internal buoyancy airbag working in a zero-pressure state (ensuring that the buoyancy gas basically does not leak), and can breathe and deform freely (expand and contract) with the alternating day and night temperature of the external environment, and adapt to the alternating day and night temperature of the external environment; the wing outer surface sweeping phenomenon formed by ram air (receiving external strong winds after the dual-redundancy active valve is opened) + micro-permeable outer skin material can effectively drain water, prevent snow accumulation, and prevent icing. It cooperates with heating film, dual-redundancy active valve, blower, heat pump and other heating internal gas circulation, efficiently melts ice, snow, dry and maintains buoyancy. In addition, the function of the first equipment cabin can effectively support air traffic control and provide warnings, does not interfere with the safety of civil aviation routes, timely detects approaching bird flocks and drives them away, and protects the air ecological environment. It has a good ability to adapt to complex high-altitude environments.

[0033] 3) Ram air + micro-permeable outer skin material form an air hysteresis pressure difference, which naturally maintains a certain internal and external pressure of the outer skin, ensures the smoothness of the outer skin flying wing configuration (low resistance), and forms a continuous sweeping phenomenon on its surface, which can improve the lift-to-drag ratio of the flying wing configuration (flow control technology). The aerodynamic shape of the tail wing and the flying wing configuration constitutes an aerodynamic layout with low resistance, high lift-to-drag ratio, self-stabilization of pitch and roll attitude, and autonomous heading to face the wind, which can achieve unmanned operation during long-term hovering, simple operation, and stable resident power generation.

[0034] 4) The rigid-flexible hybrid stable load-bearing structure system maintains the flying wing configuration, allowing the buoyancy airbag to work in a zero-pressure state. The outer skin is only used for rectification and to provide buoyancy volume (with very low pressure requirements). The performance requirements for flexible film multilayer composite materials (such as tensile strength, tear strength, deformation elongation, air tightness, etc.) are greatly reduced, making it easy to achieve low-cost production and alternative selection.

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.

[0048] Embodiment 1:

The airbag 12 works in a zero-pressure state and can expand and contract freely with the alternating temperature of the external environment during the day and night, that is, the buoyancy airbag 12 provides static buoyancy, which is redundant in function and highly safe. The zero-pressure working mode can make the leakage of the buoyant gas minimal, maintain long-term buoyancy, and reduce the performance requirements of the airbag material's air tightness, strength, processing technology, etc., which is easy to achieve low-cost production and is not limited to the selection and configuration of the airbag material; multiple wind turbines 15 are installed at the bottom of the flying wing configuration thin-walled truss load-bearing structure 11 through a supporting structure 16.

The lightweight and high-strength composite components are carbon fiber tubes or aluminum alloy tubes or high-pressure flexible air columns or a combination thereof. In this embodiment, carbon fiber tubes are selected to reduce cost and weight.

[0054] Specifically, the surfaces of the lightweight and high-strength composite components in contact with the outer skin 141 and the buoyancy airbag 12 are coated with a low absorption ratio coating or a full reflection coating or covered with an aluminum film, which can prevent the components from heating up and destroying the strength of the flexible composite materials in contact with them.
