Chinese patent with application number 2011101515270 discloses an umbrella-type wind power device and a wind power system, which comprises: a working rope arranged at an angle to the ground; the control box, the sliding barrel, the acting umbrella and the balancing device are sequentially connected to the acting rope from bottom to top, and the stability of the aerial balancing system cannot be influenced by the opening and closing of the acting umbrella, so that the aerial part of the wind energy power system provided by the invention has good stability and control performance.

However, the balance system in the invention can only provide acting force along the axial direction of the acting rope, and the pitching angle of the acting rope depends on the external wind environment. When the wind power is small, the acting rope is approximately 90 degrees and vertical to the ground; when the wind power is larger, the posture of the mooring rope is more inclined, and the pitching angle is smaller. However, the pitch angle of the acting rope is very critical, and the pitch angle directly determines the attack angle of the acting module, so that the windward area and the power output of the module are influenced. In order to obtain stable output, the pitching angle of the acting rope needs to be controllably adjusted according to the real-time wind speed.

Although the system realizes the adjustment of the working pitch angle under different high-altitude wind forces, the adjustment mode is single, and the system cannot well adapt to the use requirements of different regions and different wind conditions. When the umbrella-type wind power device is directly used as an umbrella ladder for doing work, an adjusting device needs to be arranged on each umbrella for doing work, the complexity of the system structure is increased, and the failure probability is increased due to the use of a plurality of adjusting devices.

Detailed Description

The claimed technical solution of the present invention is further described in detail with reference to the accompanying drawings and the specific embodiments.

Example 1

As shown in fig. 1 to 5, the high altitude wind balance system provided by the present embodiment includes a spherical lift guide 100 connected to a main rope 601, the lift guide 100 is partially connected along its equator direction to a deployed balance adjusting member 200 having a windward side, a portion of the balance adjusting member 200 not connected to the lift guide 100 is connected to an adjusting drive 400 provided on the main rope 601 through an adjusting rope 300, and the adjusting drive 400 can adjust the length of the adjusting rope 300; the balance adjusting piece 200 is detachably connected with the lift force guiding piece 100 and the adjusting driving piece 400, and the main rope 601 is connected to the working rope 600. The lift force guide piece 100 can be a helium balloon, the work applying rope 600 is connected with a high-altitude work applying unit 700, and the other end of the work applying rope 600 is connected to the ground module 800 to drive the ground module such as a generator to apply work.

Wherein the lift guide 100 is connected to the main rope 601 in its equatorial direction by several secondary ropes 102; specifically, the lift guide 100 is provided with a skirt 101 having concave-convex intervals along the equator direction thereof, the convex portion of the skirt 101 is connected to the main rope 601 through a plurality of the secondary ropes 102, and the convex portions of some of the skirts 101 (for example, the convex portions of half of the skirts 101) are also connected to the balance adjuster 200. Compared with the mode that the secondary rope 102 and the balance adjusting piece 200 are directly connected to the helium balloon in a single point, the design of the skirt is more beneficial to enabling the tensile force of the secondary rope to uniformly act on the stress layer of the helium balloon and preventing local tearing. If the direct connection mode is adopted, reinforcing ribs are required to be added near the contact point of the stress layer so as to disperse the tensile force.

In this embodiment, the balance adjusting member 200 is formed in a triangular spherical surface shape, and the angle of the triangular spherical surface, which is not connected to the skirt 101, is connected to the adjusting driving member 400 through the adjusting rope 300.

Wherein, the windward side of the balance adjusting piece 200 is provided with a plurality of air holes 201 for maintaining the balance of the balance adjusting piece 200 and simultaneously improving the lifting force thereof.

Specifically, the adjusting driving member 400 includes a wind condition sensing module connected to an MCU (micro controller Unit) disposed therein for collecting wind speed, wind direction, and the like, a GPS, and a wireless transceiver module, and the adjusting driving member 400 is further provided with a power supply module (e.g., a small wind power generator) for supplying power thereto, and the wireless transceiver module is connected to the ground module 800. The adjusting driving member 400 directly adjusts the length of the adjusting rope 300 according to wind conditions and/or position information; alternatively, the adjusting driving member 400 transmits the wind condition and/or the position information to the ground module 800, and then adjusts the length of the adjusting rope 300 according to the adjusting instruction of the ground module 800. The adjusting driving member 400 is provided with a winding machine, and the length of the adjusting rope 300 is controlled by controlling the winding machine.

Specifically, the main rope 601 located at the lower portion of the adjustment driving member 400 is connected to the circumferential rotation connection mechanism 500; the circumferential rotating connection mechanism 500 comprises an upper connection piece 501 and a lower connection piece 505 which are connected, wherein the upper connection piece 501 can rotate relative to the lower connection piece 505; the main rope 601 is connected with the upper connecting piece 501, and the lower connecting piece 505 is connected with the acting rope 600.

More specifically, as shown in fig. 4, the circumferential rotation connection mechanism 500 includes a housing, in which an upper connection member 501 is provided to be rotatable therein, and a lower connection member 505 is provided at a lower portion of the housing. Two deep groove ball bearings 502 and 503 are arranged between the upper connecting piece 501 and the shell at intervals up and down, a plane bearing 504 is arranged below the deep groove ball bearing at the lower part, when the upper connecting piece 501 and the main rope 601 are disturbed by the helium balloon or/and the balance adjusting piece 200 to rotate, the lower connecting piece 505 does not rotate together, and therefore the main acting rope can be guaranteed not to be disturbed by the helium balloon balance system to be twisted and rotated at any time, and the like, as shown in fig. 8.

The triangular spherical balance adjusting piece provided by the embodiment is suitable for a single rope system without limitation on the use direction of an empty space. As shown in fig. 1, when the helium balloon is lifted off and pulls the main rope 601 and the working rope 600 and the working unit 700 mounted thereon to reach a predetermined altitude step by step, the adjusting driving member 400 drives the winch to synchronously adjust the length of the adjusting rope 300 according to the real-time monitored wind condition, the real-time pitch angle and the preset working pitch angle.

Fig. 2 is a schematic diagram showing the force analysis of the rope and the pitch angle of the working rope, where F1 is the resultant of the wind force and buoyancy applied to the helium balloon by the helium balloon and the pulling force applied to the helium balloon by the balance adjuster 200 through the skirt, F2 is the pulling force applied to the adjusting rope 300, and F3 is the influence of the working rope and its additional modules. In fact, in the time period when the work doing unit 700 is expanded to do work, the work doing ropes below the work doing unit 700 are pulled by the great pulling force generated by the work doing unit 700, and the work doing ropes on the upper part of the work doing unit are relatively small in F3, so the pitch angle of the main work doing ropes is mainly controlled and guided by F1 and F2.

Generally, high-altitude wind mainly flows nearly horizontally. In order to obtain high-altitude wind energy as much as possible, the pitch angle of the working rope is generally set to be 30 to 60 degrees and less than 30 degrees, potential risks are possibly caused to ground facilities and the like, and if the pitch angle is more than 60 degrees, the maximum power output is difficult to obtain. The specific balancing process of the high-altitude wind power balancing system provided by the embodiment is as follows:

1) When the high-altitude wind speed is too large: the lift guide 100 and the balance adjuster 200 will bring the work line 600 down the pitch angle. At this time, the adjusting driving member 400 controls the winding machine to extend the length L of the adjusting rope 300. Under the action of wind, the balance adjustment member 200 will rise, thereby reducing its frontal area. Accordingly, the lateral force applied to the lift guide 100 and the balance adjusting member 200 as a whole is reduced (i.e., the sum of the horizontal components of F1 and F2), but the lift force is increased (i.e., the upward lift force applied to the balance adjusting driving member), so that the pitch angle of the working rope 600 is restored to the preset range.

2) When the high wind speed is too small, the lift force guide piece 100 and the balance adjustment piece 200 will drive the acting rope 600 to increase the pitch angle. At this time, the adjusting drive 400 controls the winding machine to shorten the length L of the adjusting rope 300, and the balance adjusting member 200 is pulled down, so that the windward area of the balance adjusting member 200 is increased. Accordingly, the lateral force applied to the lift force guide 100 and the balance adjustment member 200 as a whole (i.e., the sum of the horizontal component forces of F1 and F2) is increased, so that the pitch angle of the working rope 600 is restored to the preset range.

In addition, the system can also send out a proper pitch angle instruction by the control system of the ground module 800 according to the air control requirement and the wind condition of the work area, and the pitch angle can be flexibly adjusted by the adjusting driving piece 400. Fig. 5 is a schematic view showing that the working rope 600 obtains a smaller pitch angle by adjusting the length L of the adjusting rope 300 or replacing the balance adjusting member 200 properly under the same wind conditions.

Example 2

As shown in fig. 6 to 7, the high altitude wind balance system provided by the present embodiment includes a spherical lift guide 100 connected to a main rope 601, the lift guide 100 is partially connected along its equator direction to a balance adjuster 200 deployed with a windward side, the portion of the balance adjuster 200 not connected to the lift guide 100 is connected to an adjustment driving member 400 provided on the main rope 601 through an adjustment rope 300, and the adjustment driving member 400 can adjust the length of the adjustment rope 300; the balance adjusting piece 200 is detachably connected with the lift force guiding piece 100 and the adjusting driving piece 400, and the main rope 601 is connected to the working rope 600. The lift force guide piece 100 can be a helium balloon, the acting rope 600 is connected with a high-altitude acting unit 700, and the other end of the acting rope 600 is connected to the ground module 800 to drive the ground module such as a generator to act.

Wherein the lift guide 100 is connected to the main rope 601 in its equatorial direction by several secondary ropes 102; specifically, the lift force guide 100 is provided with a skirt 101 with concave-convex intervals along the equator direction thereof, the convex part of the skirt 101 is connected to the main rope 601 through a plurality of the secondary ropes 102, and the convex parts of part of the skirt 101 (for example, the convex parts of half of the skirt 101) are also connected to the balance adjuster 200. Compared with the mode that the secondary rope 102 and the balance adjusting piece 200 are directly connected to the helium balloon in a single point, the design of the skirt is more beneficial to enabling the tensile force of the secondary rope to uniformly act on the stress layer of the helium balloon and preventing local tearing. If the direct connection mode is adopted, reinforcing ribs are required to be added near the contact point of the stress layer so as to disperse the tensile force.

In this embodiment, the balance adjusting member 200 is at least a square spherical shape, wherein the corners not connected to the skirt 101 are respectively connected to the adjusting driving member 400 through the adjusting ropes 300, and the adjusting driving member 400 can adjust the length of each adjusting rope 300 simultaneously or respectively. When the direction of the acting rope needs to be changed, the adjusting driving piece respectively adjusts the length of each adjusting rope connected between the adjusting driving piece and the balance adjusting piece, so that each adjusting rope has different lengths, at the moment, the windward side of the balance adjusting piece 200 is not symmetrical relative to the wind direction any more, a lateral component force acts on the balance adjusting piece 200, the component force can form a deflection force on the lift force guide piece through the balance adjusting piece, and the lift force guide piece is driven by the deflection force to deflect, so that the acting rope is driven to deflect. Relative to the ground anchor point, the force can drive the whole aerial system to deflect and reach balance at a certain angle. In this embodiment, when the length difference of the adjusting ropes 300 is gradually increased, the deflection angle is larger, but does not exceed an upper limit value. The "deflection" described in this embodiment refers to the change of the projection angle of the power cord on the ground — actually, the spatial orientation is also changed, as shown in fig. 9.

The windward side of the balance adjusting member 200 is further provided with a plurality of air holes 201 for maintaining the balance of the balance adjusting member 200 and simultaneously improving the lift force thereof.

Specifically, the adjusting driving member 400 includes a wind condition sensing module connected to the MCU disposed therein for collecting wind speed, wind direction, etc., a GPS, and a wireless transceiver module, and the adjusting driving member 400 is further provided with a power supply module (e.g., a small wind power generator) for supplying power thereto, and the wireless transceiver module is connected to the ground module 800. The adjusting driving member 400 directly adjusts the length of the adjusting rope 300 according to wind conditions and/or position information; alternatively, the adjusting driving member 400 transmits the wind condition and/or the position information to the ground module 800, and then adjusts the length of the adjusting rope 300 according to the adjusting instruction of the ground module 800. The adjusting driving member 400 is provided with a winding machine corresponding to each adjusting rope 300, and the length of the adjusting rope 300 is controlled by the winding machine.

Specifically, the main rope 601 located at the lower portion of the adjustment driving member 400 is connected to the circumferential rotation connection mechanism 500; the circumferential rotating connection mechanism 500 comprises an upper connection piece 501 and a lower connection piece 505 which are connected, wherein the upper connection piece 501 can rotate relative to the lower connection piece 505; the main rope 601 is connected with the upper connecting piece 501, and the lower connecting piece 505 is connected with the acting rope 600.

More specifically, as shown in fig. 4, the circumferential rotation connecting mechanism 500 includes a housing, in which an upper connecting member 501 is provided to be rotatable therein, and a lower connecting member 505 is provided at a lower portion of the housing. Two deep groove ball bearings 502 and 503 are arranged between the upper connecting piece 501 and the shell at intervals up and down, a plane bearing 504 is arranged below the deep groove ball bearing at the lower part, when the upper connecting piece 501 and the main rope 601 are disturbed by the helium balloon or/and the balance adjusting piece 200 to rotate, the lower connecting piece 505 cannot rotate together, and therefore the main acting rope cannot be disturbed by the helium balloon balance system to generate risks of twisting and rotating and the like at any time.

The multi-angle spherical balance adjusting piece provided by the embodiment is not only suitable for the application occasions of the embodiment 1, but also suitable for complex occasions such as limited airspace use directions, changeable wind directions and/or multiple groups of acting ropes.

Taking a simpler four-corner spherical balance adjustment member as an example, as shown in fig. 6, after the lift force guide 100 is lifted off, the main rope 601 and the acting rope 600 and the acting unit 700 mounted thereon are pulled to reach a predetermined altitude step by step. Meanwhile, the adjusting driving member 400 drives two winches to synchronously adjust the lengths of the two adjusting ropes 300 or independently drives one of the two winches to adjust the length of one of the adjusting ropes according to the real-time monitored wind power condition, the real-time pitch angle and the preset work-doing pitch angle.

Specifically, the specific balancing process of the high altitude wind power balancing system in this embodiment is as follows:

1) When the high altitude wind speed is too high, the lift force guide piece 100 and the balance adjustment piece 200 will drive the acting rope 600 to reduce the pitch angle. At this time, the adjusting driving member 400 controls the winch to synchronously extend the lengths L1 and L2 of the two adjusting ropes 300. Under the action of wind, the balance adjuster 200 is raised, so that the windward area of the balance adjuster 200 is reduced. Accordingly, the lateral force applied to the lift guide 100 and the balance adjuster 200 as a whole is reduced, but the lift force is increased, so that the pitch angle of the working rope 600 is restored to a predetermined range.

2) When the high wind speed is too small, the lift force guide piece 100 and the balance adjustment piece 200 will drive the acting rope 600 to increase the pitch angle. At this time, the adjusting drive 400 controls the winch to synchronously shorten the lengths L1 and L2 of the two adjusting ropes 300. At this time, the balance adjuster 200 is pulled down, so that the windward area of the balance adjuster 200 is increased. Accordingly, the lateral force applied to the entire lift guide 100 and the balance adjuster 200 is increased, so that the pitch angle of the work rope 600 is restored to a predetermined range.

3) When the direction of the working rope needs to be adjusted, the adjusting driving part 400 drives the two winches to adjust the lengths L1 and L2 of the two adjusting ropes 300 respectively. When the lengths of the L1 and the L2 are unequal, the windward side is subjected to a deflection force, and the force is applied to the lift force guide piece 100 through the skirt 101, so that the lift force guide piece deflects in the air, and all the components such as the auxiliary rope 102, the main rope 601, the circumferential rotating connecting mechanism 500, the acting rope 600 at the lower end of the circumferential rotating connecting mechanism, the acting unit 700 attached to the acting rope 600 and the like are driven to integrally deflect around the ground module 800 at a certain angle, and the adjustment of the acting direction (airspace) of the whole aerial system is realized.

Taking fig. 7 as an example, when the length L1 of one of the adjusting ropes 300 is greater than the length L2 of the other adjusting rope 300, the balance adjusting member 200 will receive a deflecting force (from the top to the bottom) in the counterclockwise direction around the ground module 800, and at this time, the balance adjusting member 200 and the lift force guide 100 will drive the main rope 601, the circumferential rotation mechanism 500 and the working rope 600 at the lower end thereof, and all the parts such as the working unit 700 attached to the working rope 600 to deflect counterclockwise (from the top to the bottom) around the ground module 800 together, and reach balance at a certain angle. Conversely, when the length L1 of one of the adjusting ropes 300 is smaller than the length L2 of the other adjusting rope 300, the balance adjusting member 200 will receive a deflection force (from the top to the bottom) in the clockwise direction around the ground module 800, and at this time, the balance adjusting member 200 and the lift force guiding member 100 will drive the main rope 601, the circumferential rotating mechanism 500, the working rope 600 at the lower end thereof, and all the components such as the working unit 700 attached to the working rope 600 to deflect clockwise (from the top to the bottom) around the ground module 800 together, and reach balance at a certain angle.

In addition, as in embodiment 1, the system may also send out a proper pitch angle command by the control system of the ground module 800 according to the air control requirement and the wind condition in the work area, and the pitch angle and the direction are flexibly adjusted by the adjusting driving member 400.

The above-mentioned embodiments are merely illustrative and not restrictive, and various modifications and improvements made by the technical solutions of the present invention by those skilled in the art should fall within the scope of the present invention as defined in the appended claims without departing from the spirit of the present invention.
