Description

A high altitude wind energy operation platform and its use method Technical Field

[0001] The invention relates to a high-altitude wind energy operation platform and a use method thereof, belonging to the technical field of high-altitude wind energy utilization. Background Art

[0002] High-altitude wind energy is a new energy source that has been largely unexploited by humans. It is a renewable clean energy source with abundant reserves and widespread distribution. Wind energy P is proportional to the cube of wind speed (P = 0.5ρv 3 (ρ - air density, v - wind speed) A doubling of wind speed increases wind energy by a factor of eight (the standard air density is 1.225 kg / m, while the air density at 6,000 meters is approximately 0.644 kg / m, a decrease of only about 1). Therefore, high-altitude wind energy can be several, dozens, even hundreds, of times higher than that on the ground. High-altitude winds are constant and stable year-round. Within a few kilometers of the ground, the higher the altitude, the stronger and more stable the wind. Therefore, harvesting high-altitude wind energy for power generation can produce highly stable wind power at a low cost. This is one of the notable characteristics of high-altitude wind power and one of its most significant advantages over conventional wind power. However, utilizing high-altitude wind energy is a challenge. Chinese patents CN201610200583.1, titled "A High-Altitude Wind Energy Generation System and a High-Altitude Wind Energy Generation Capsule," and CN201711299009.7, titled "A Control Method for a Medium- and High-Altitude Wind Energy Generation System," all utilize kite-like umbrella-shaped power conversion devices to generate electricity from high-altitude wind energy. However, these power conversion devices are bulky at high altitudes and require ground-based traction control. Due to the high force generated by high-altitude wind energy, it is difficult to stably control these devices on the ground. Chinese invention patents CN201310279788.X, titled "Kite Flying Along Track-Type Power Generation Method," and CN201410067063.9, titled "Kite Flying Along a Rolling-Escalator Track-Type Power Generation Method," propose methods that utilize a linear track on the ground with a cable attached to it to control the high-altitude kite. However, due to the constantly changing direction of high-altitude wind, the linear track on the ground struggles to adapt to these changes in direction. In addition, the existing technologies all place a single electric energy conversion device at high altitude to generate electricity, without forming an operating platform that can stay in the air for a long time, which is very inconvenient and also limits the use of high altitude.

[0003] Summary of the Invention

[0004] The purpose of the present invention is to provide a high-altitude wind energy work platform and a method of use. It can be combined into a giant high-altitude platform as needed to carry out various work and operations, and it reduces many unnecessary connections and intermediate links. The most important thing is that it can be controlled by the 360-degree release ropes on the ground circular track in very high wind speeds, so that the platform can stay in the air very stably for a long time.

[0005] The technical solution of the present invention is:

[0006] A high-altitude wind energy operation platform includes a kite platform, a circular track, ropes and sliders. The circular track is set on the ground, the kite platform is set in the air, and multiple sliders are set on the circular track. The kite platform is connected to the sliders through multiple ropes. The sliders slide on the circular track and will not fall off the circular track.

[0007] The kite platform is composed of a plurality of wind tubes arranged and combined in parallel. The wind tubes are in the shape of long cylinders with open ends made of flexible material. Adjacent wind tubes are connected by connectors to form the kite platform. The central axis of the wind tube is parallel to the ground or has an inclination angle. The greater the windward angle, the greater the inclination angle between the central axis of the wind tube and the ground. The higher the high-altitude wind speed, the closer the central axis of the wind tube is to being parallel to the ground.

[0008] The air duct is in a cone shape, with a larger diameter at the air inlet and a smaller diameter at the air outlet.

[0009] The cross-sectional shape of the air duct is arbitrary, including: a circular air duct, a rectangular air duct, and the like.

[0010] The slider and ropes work together to form a combined device for towing the kite-flying platform. The slider is a track vehicle that travels 360 degrees on a circular track. A winch is installed on the slider. The ropes for flying the kite platform are wound around the winch, which adjusts the rope length at any time to retract and extend the kite. Sensors and control software can be used to automatically control the ropes' extension and retraction, allowing the kite platform to be stably controlled at all times. The invention uses a program to control the extension and retraction of the kite platform as required, which is a well-known and commonly used technical means in the art.

[0011] A method for using a high-altitude wind energy operation platform, wherein wind tubes are connected to each other by connectors, including horizontal and vertical connections; a plurality of wind tubes are combined into an array-type giant kite platform; the giant kite platform can carry various instruments and equipment to perform operations and work stably at high altitudes for a long time, including:

[0012] a. Install water vapor interception nets and equipment in each air duct to intercept water vapor in the air for a long time, so that the water vapor condenses into water and flows to the ground for a long time to form lakes or rivers on the ground;

[0013] b. Install propeller or turbofan wind power generation equipment in each wind tube to generate electricity stably and long-term;

[0014] c. Carrying and hanging high-altitude radar to monitor a wide range of airspace in a long-term and stable manner;

[0015] d. Equipped with and suspended with various monitoring equipment and video equipment, it can provide long-term and stable monitoring of a large area of ​​surrounding space;

[0016] e. Ropes are suspended from the giant kite platform all the way to the ground, and various meteorological equipment can be hung at various heights to stably monitor and collect meteorological data at different altitudes around the clock.

[0017] f. Install solar panels on the top and sides of the kite platform to generate electricity using solar energy.

[0018] A method for launching a high-altitude wind energy work platform. The sizes of the kite platforms are assembled as needed, either on the ground or in the air. The kite platforms are towed, launched, and adjusted by ropes on a circular track on the ground. No matter how strong the wind is or how the wind direction changes, the sliders slide in accordance with the movement on the circular track, allowing the kite platform to stay in the air stably for a long time against the wind, thus becoming a long-term stable high-altitude work platform.

[0019] The kite platform can be flown to an altitude of 500 meters, 1 kilometer, 3 kilometers, 5 kilometers, or even 10,000 meters. The ropes pulling the kite platform can be adjusted at any time based on the data sent back by various sensors, so that the kite platform can stay in the air stably for a long time.

[0020] Specific usage and operation methods: Build a foundation and a circular track on the ground. There is a tractor composed of sliders on the circular track. The tractor can move on the circular track through the sensing system and the walking system. There is a winch on the tractor for retracting and releasing the rope. The flying of the high-altitude kite platform is controlled by the sensing system and the power system.

[0021] According to the needs, the wind tubes are combined and connected to form a rectangular or square kite platform, and the flying ropes are connected. The characteristic of the connection is that there are several ropes in four directions for connection.

[0022] According to different wind speeds, the kite platform is released by adjusting the angle of attack of each rope. The larger the angle of attack, the greater its lift. When the kite platform is released to a predetermined height, the angle facing the wind is adjusted to make it stay stable at high altitude, and then switch to automatic control mode to automatically control and fine-tune each traction rope anytime and anywhere to ensure the kite platform flies stably at high altitude.

[0023] The beneficial effects of the present invention are as follows: 1. The high-altitude wind tube combination integrated array giant kite platform can be combined as needed to form a giant high-altitude platform, capable of carrying out a variety of work and operations while reducing many unnecessary connections and intermediate links. Most importantly, it can remain stable at high altitude for long periods of time in very high wind speeds. 2. The ground-based circular track can be made infinitely large as needed. The high-altitude giant kite platform is automatically controlled around the clock by multiple rope tractors on the circular track. The platform can be repositioned 360 degrees on the circular track according to wind direction, allowing the platform to remain stable at high altitude for long periods of time.

[0034] The kite platform 1 is composed of a plurality of wind tubes arranged and combined in parallel. The wind tubes are in the shape of long cylinders with open ends made of flexible material. Adjacent wind tubes are connected by connectors to form the kite platform 1. The central axis of the wind tube is parallel to the ground or has an inclination angle. The greater the windward angle, the greater the inclination angle between the central axis of the wind tube and the ground. The higher the high-altitude wind speed, the closer the central axis of the wind tube is to being parallel to the ground.

[0035] The air duct is in a cone shape, with a larger diameter at the air inlet and a smaller diameter at the air outlet.

[0036] The cross-sectional shape of the air cylinder is arbitrary.

[0039] The slider 4, in conjunction with the rope 3, forms the combined device for towing the kite-flying platform 1. The slider 4 is a track vehicle that travels 360 degrees on a circular track. A hoist 7 is mounted above the slider 4. The rope 3 of the kite-flying platform 1 is wound around the hoist 7, which adjusts the length of the rope 3 at any time, allowing it to be retracted or extended. Sensors and control software automatically control the rope's retraction and extension, providing stable, all-weather control of the kite platform 1 at high altitude. The invention utilizes a program to control the retraction and extension as required, a well-known and commonly used technique in the art.

[0040] A method for using a high-altitude wind energy operation platform, wherein wind tubes are connected to each other by connectors, including horizontal and vertical connections; a plurality of wind tubes are combined into an array-type giant kite platform 1; the giant kite platform 1 can carry various instruments and equipment to perform long-term and stable operations at high altitudes, including:

[0041] a. Install water vapor interception nets and equipment in each air duct to intercept water vapor in the air for a long time, so that the water vapor condenses into water and flows to the ground for a long time to form lakes or rivers on the ground;

[0042] b. Install propeller or turbofan wind power generation equipment in each wind tube to generate electricity stably in a long term;

[0043] c. Carrying and hanging high-altitude radar to monitor a wide range of airspace in a long-term and stable manner;

[0044] d. Equipped with and suspended with various monitoring equipment and video equipment, it can provide long-term and stable monitoring of a large area of ​​surrounding space;

[0045] e. Ropes are suspended from the giant kite platform all the way to the ground, and various meteorological equipment can be hung at various heights to stably monitor and collect meteorological data at different altitudes around the clock.

[0046] f. Install solar panels on the top and sides of the kite platform to generate electricity using solar energy.

[0047] In an embodiment, the kite platform 1 of the present invention is flown at an altitude of 6,000 meters, the diameter of the circular track 2 is 10 kilometers, the number of the sliders and ropes is 80, and the inclination angle of the ropes is 45°.

[0048] A method for launching a high-altitude wind energy work platform. The kite platforms are assembled in different sizes according to needs, either on the ground or in the air. The kite platform 1 is towed, launched, and adjusted by a rope 3 on a circular track 2 on the ground. No matter how strong the wind is or how the wind direction changes, a slider 4 slides along the circular track to keep the kite platform 1 stable in the air against the wind for a long time, thus becoming a long-term stable high-altitude work platform.

[0049] The kite platform can be flown to an altitude of 500 meters, 1 kilometer, 3 kilometers, 5 kilometers, or even 10,000 meters. The ropes pulling the kite platform can be adjusted at any time based on the data sent back by various sensors, so that the kite platform can stay in the air stably for a long time.

[0050] Specific usage and operation methods: Build a foundation and a circular track on the ground. There is a tractor composed of sliders on the circular track. The tractor can move on the circular track through the sensing system and the walking system. There is a winch on the tractor for retracting and releasing the rope. The flying of the high-altitude kite platform is controlled by the sensing system and the power system.

[0051] According to the need, the wind tubes are combined and connected to form a rectangular or square kite platform 1, and the flying rope 3 is connected. The characteristic of the connection is that there are several ropes in four directions for connection.

[0052] According to different wind speeds, the kite platform is released by adjusting the angle of attack of each rope. The larger the angle of attack, the greater its lift. When the kite platform is released to a predetermined height, the angle facing the wind is adjusted to make it stay stable at high altitude, and then switch to automatic control mode to automatically control and fine-tune each traction rope anytime and anywhere to ensure the kite platform flies stably at high altitude.

[0053] Specific release process;

[0054] Choose a windy day (wind level 3 or 4 or above will do). If you release the kite directly, the lift required to fly it to a high altitude is very large; release the kite platform and related equipment together.

[0055] If the equipment to be placed on the kite platform is relatively heavy, you can first place a row of empty wind tubes or a combination of two rows of empty wind tubes horizontally, and place them tens or hundreds of meters high. Then use the same rope to connect the wind tubes carrying the equipment, and use the upper row or two rows of empty wind tubes to lift these wind tubes carrying equipment into the sky.

[0056] All wind tubes are connected to ropes for release. Each rope can be controlled at any time and place to adjust the wind tube's angle of attack to ensure overall smooth release. When carrying equipment to high altitudes, the equipment that needs to be suspended can be tightly combined with the wind tubes in the air through high-altitude connecting components.
