As shown in fig. 1 to 7, the foldable high-altitude acting system in this embodiment includes a acting rope 501 connected to a ground system, and the acting rope 501 is provided with a balancing module and a acting module in sequence from top to bottom; the acting module is fixedly connected to the acting rope 501 and has a windward side; the acting module automatically unfolds the windward side when reaching the acting lower limit height and automatically folds the windward side when reaching the acting upper limit height. The entire system is connected to a ground system via a work line 501 to power ground modules (e.g., generators or other mechanical devices).

In this embodiment, the lower limit working height mainly considers cut-in wind speed and altitude, and autonomous control of the working height interval can be realized through the anemometer and the altimeter, and meanwhile, the wireless module can be adopted to realize manual intervention adjustment of the ground station according to actual needs. Similar to the determination of the lower limit height of work, an anemometer and an altimeter can be adopted, and the pull-up length of the work rope 501 is determined by combining a wireless module.

Specifically, the work module has a sail-shaped configuration, a sail surface 301 of the sail-shaped configuration forms the windward side, the sail surface 301 is connected to a sail surface control module 101 for controlling the sail surface 301 to unfold or fold, the sail surface control module 101 is arranged in the center of the upper sail surface and fixedly connected to the work rope 501, and the work rope 501 penetrates through the center of the sail surface control module 101. The sail surface material can be made of low-density high-strength corrosion-resistant flexible fabrics such as ultra-high molecular polyethylene and the like so as to meet the requirements for work application and reliability.

Specifically, the sail surface 301 is provided with a first retractable member, and the sail surface control module 101 is connected with the first retractable member, and controls the folding or unfolding of the sail surface 301 by controlling the folding or unfolding of the first retractable member. The first retractable piece can be set as a sail surface storage rope connected with the sail surface 301, the sail surface storage rope comprises a first sail surface storage rope 201 and a second sail surface storage rope 202 which are perpendicular to each other on the sail surface, a plurality of ear ropes 302 which are matched with the first sail surface storage rope 201 and the second sail surface storage rope 202 to achieve telescopic storage of the sail surface are further arranged on the sail surface 301, and the first sail surface storage rope 201 and the second sail surface storage rope 202 penetrate through the ear ropes 302 respectively.

The sail surface control module 101 is provided with a low-power winch which is connected with the sail surface storage rope, and the folding or unfolding of the sail surface 301 is controlled by controlling the winding, lifting and length of the sail surface storage rope. Depending on the application, a low density, high strength rigid telescoping system may be used instead of the storage rope.

More specifically, the sail surface control module 101 also includes a spinner; the rotator is connected to the first retractable member for controlling the angle of the sail surface 301 to fold or unfold. The rotator can be arranged as a rotatable sleeve 102, the sail surface storage rope passes through the rotatable sleeve 102, the rotatable sleeve 102 is arranged to enable the edge of the sail surface 301 to controllably rotate around the winch shaft, the sail surface storage rope is prevented from being rolled in when the sail surface 301 is folded and contracted, the direction of the sail surface can be controlled when the sail surface is folded and stored, and the sail surface can be favorably unfolded facing the wind.

In particular, the rotatable sleeve 102 in this embodiment has three roles. One of them effect is to be convenient for accomodate the rope and retrieve, can compare figure 1 and figure 5. In the case of maximum windward side as shown in fig. 1, the rotatable sleeve is almost perpendicular to the power cord 501. In the situation shown in fig. 5, after the sail rope is released, the wind energy from high altitude blows the sail surface to raise, and at this time, the rotatable sleeve 102 will also rotate upwards to a suitable angle, so as to facilitate the retraction of the sail surface storage rope 201.

Another function of the sleeve is that when the sail surface is ready to be deployed, the sleeve is upward, so that the sail surface forms a small wind inlet, and the sail surface blows out gradually in the right direction. The third function of the sleeve is that under the condition that the high altitude wind energy density exceeds the rated requirement, the sail face windward area is smaller than that of the case shown in the attached figure 1 by properly reducing the release length of the sail rope 601 and properly adjusting the angle (downward rotation) of the rotating sleeve, so that the purpose of adjusting the output power is achieved.

In particular, said sail surface 301 is connected to a second control module 701 by means of a second retractable element; the second control module 701 is located below the sail surface 301 and is fixedly connected to the power cord 501, and the folding or unfolding of the sail surface 301 is controlled by controlling the unfolding or folding of the second retractable member. Wherein a second retractable element may be provided as a sail string 601 connected to the sail surface 301. The second control module 701 is also provided with a low-power winch connected to the sail rope to control the folding or unfolding of the sail 301 by controlling the raising, rolling and length of the sail rope.

Specifically, the system includes a power module that provides power to the sail surface control module 101 and the second control module 701. The power consumed by the system is from a wind power generation device arranged near the acting module, and the system power can be transmitted through a power supply line wrapped at the core part of the acting rope 501 or arranged outside the acting rope. The wind power generating system further comprises a controller, a sensor module for acquiring height and wind speed and a wireless transmission module, wherein the controller is connected to the sail surface control module 101 and the second control module 701 through the wireless transmission module.

The sensor module transmits the acquired information such as height and wind speed to the controller, and the controller controls the unfolding/folding degree and angle of the sail surface 301 by controlling windlasses (and rotating sleeves) in the sail surface control module 101 and the second control module 701.

Specifically, the balancing module includes a helium balloon 401. For a system of a working module, the working module should be located at a safe distance below the balance module, that is, when the sail surface 301 of the working module reaches the highest working point to be turned over, the working module does not touch the balance module and related components (such as the wind power generation device, etc., which is not specifically described herein due to its simple structure).

The working process of the foldable high-altitude power sail system provided by the embodiment is as follows (taking the foldable high-altitude power sail system comprising one working module as an example):

1) As shown in FIG. 3, the system balances the system body counterweight through the 401 helium balloon balancing module and maintains the approximate pull-up direction of the working line. When the acting rope 501 is in a descending state, the sail surface control module 101 controls the winch to tighten the first sail surface storage rope 201 and the second sail surface storage rope 202, so that the sail surface 301 is in a folded state, and the sail surface 301 does not have an obvious windward surface, so that the sail surface 301 can be conveniently recovered to the lower acting limit height along with the acting rope 501.

2) As shown in fig. 4, when the system reaches the initial position of work (i.e. the lower height of work), the sail surface control module 101 controls the winch to release the first sail surface storage rope 201 and the second sail surface storage rope 202, so that the sail surface 301 can be freely extended. Meanwhile, the second control module 701 pulls the sail rope 601 through the windlass, and meanwhile, the sail surface 301 is provided with a certain windward side by matching with the rotatable sleeve 102 in the sail surface control module 101. At this time, the high-altitude wind can rapidly blow the sail surface 301, and drive the first sail surface storage rope 201 and the second sail surface storage rope 202 to extend, and gradually generate a pulling force on the sail rope 601. When second control module 701 controls the length of sail rope 601 to extend to a desired position (e.g., a work radius), sail rope 601 is immediately clamped (via a winch brake system or another clamping device) and sail rope 601 is no longer extended.

3) As shown in fig. 1, when the sail surface 301 is expanded to a proper size, the sail surface control module 101 also immediately clamps the first sail surface storage rope 201 and the second sail surface storage rope 202, and simultaneously clamps (by a winch brake system or another clamping device) the angle of the rotatable sleeve 102 to a proper position. At this time, high-altitude wind generates huge pulling force on the sail rope 601 through the sail surface 301, and transmits the huge pulling force to the acting rope 501, and then the acting rope 501 drives the ground system to work.

4) As shown in fig. 5, when the working rope runs to the upper limit (i.e. the working upper limit height), the second control module 701 releases the sailing rope 601 quickly, and at the same time, the sail surface control module 101 also releases the angular latch of the rotatable sleeve 102, so that the sail surface 301 is turned over under the driving of the high-altitude wind force, so that the windward side is reduced quickly.

5) The sail surface control module 101 then rapidly retracts the first 201 and second 202 sail surface stowing lines, causing the sail surface 301 to collapse rapidly, further minimizing the frontal area of the sail surface 301. At the same time, second control module 701 also cooperates to retract sail line 601 to its proper length. After the relevant action, the sail surface 301 is restored to the initial state of fig. 3.

6) When the sail surface 301 is in a folded state, the ground system can quickly retract the working rope 501 through the winch with a small force, so that the sail descends to the lower limit height of working, and then the system starts to work for a new round.

Example 2

The foldable high-altitude power sail system provided by the embodiment is formed by arranging a plurality of power modules in a stepped mode (as shown in fig. 6). The position of the topmost sail surface 301 is similar to that of embodiment 1, and the sail groups are sequentially arranged at a safe distance. The rest of the structure and the working principle are consistent with the embodiment 1.

The above-mentioned embodiments are only exemplary descriptions, not limiting the scope of the present invention, and various modifications and improvements made by those skilled in the art without departing from the design spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
