Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of high-altitude wind energy, in particular to a high-altitude wind energy doing work system. BACKGROUND

[0002] High-altitude wind energy generally refers to the wind energy in the middle and high altitudes above 300 meters from the ground. With the increase of altitude, the average wind speed also increases. The umbrella-ladder combined high-altitude wind energy power generation system is one of the current technical solutions for generating electricity by using high-altitude wind energy. In the system, the driving member located above and / or below the doing work umbrella can walk on the main cable to assist the opening and closing of the doing work umbrella. Since the upper driving member and / or the lower driving member have a large weight, and need to walk repeatedly and quickly on the main cable and accurately reach and stay at the predetermined position, the climbing nail belt type or friction type walking mode is generally used.

[0003] For example, CN200910190150.2 discloses a high-power umbrella-type wind power generation system, which includes a main cable guided by a helium balloon, at least one doing work umbrella is arranged on the main cable, and the doing work umbrella includes two upper and lower drives that can walk freely on the main cable. The upper drive can drive the umbrella top to walk up and down on the main cable. The umbrella circumference of the doing work umbrella is connected to the lower drive through several umbrella ropes, the lower drive is associated with a sleeve fixed on the main cable, and can be connected and separated with the sleeve under control. When the umbrella is opened, the lower drive is connected with the sleeve, the high-altitude wind force acting on the umbrella surface is transmitted to the lower drive through the umbrella ropes, and then transmitted to the main cable through the sleeve, and the ground system is pulled by the main cable to do work or generate electricity. When the aerial system reaches the upper limit of the altitude, the system is controlled to close the umbrella, at this time the lower drive is separated from the sleeve, and quickly walks up for a distance, at this time the doing work umbrella will be folded by the wind, and the upper drive walks down and pushes the lower drive to connect with the sleeve again, and the aerial module is pulled down to the lower limit of the altitude by the ground system. Then, the upper drive walks up to the predetermined position on the main cable, and the system is opened again.

[0004] The above walking mode not only needs to consume a lot of energy, but also poses a great challenge to the endurance of the drive. At the same time, the climbing nail type or friction type walking needs to generate a large holding force on the main cable, which will cause a large wear on the main cable, affecting the reliability of the system for long-term work. UTILITY MODEL CONTENT

[0005] The purpose of the present disclosure is to reduce the holding friction between the driving member and the main cable in the high-altitude wind energy doing work system to reduce the wear on the main cable during walking, and to reduce the energy consumption of the driving member.

[0006] To achieve the above purpose, the present disclosure adopts the following technical solutions:

[0007] The application provides a high-altitude wind energy working system, which comprises a main cable, a working umbrella, a mooring device and a driving assembly; one end of the main cable is connected to the mooring device, and the other end is connected to ground equipment;

[0008] The main cable passes through an umbrella top opening of the working umbrella, the umbrella top opening is connected to a first walking mechanism through a plurality of first umbrella ropes, and the umbrella periphery of the working umbrella is connected to a second walking mechanism arranged below the working umbrella through a plurality of second umbrella ropes.

[0009] The driving assembly comprises a first driving, a second driving and a third driving fixed on the main cable; the first driving and the second driving are arranged above and below the working umbrella respectively and are connected to the first walking mechanism, and jointly control the first walking mechanism to slide up and down along the main cable.

[0010] The third driving is connected to the second walking mechanism and is used for controlling the second walking mechanism to slide up and down along the main cable.

[0011] Preferably, the first driving and the second driving are connected to the first walking mechanism through a first control rope and a second control rope respectively, the first driving controls the winding and unwinding of the first control rope, and the second driving controls the winding and unwinding of the second control rope.

[0012] Preferably, the third driving is connected to the second walking mechanism through a third control rope, and the third driving controls the winding and unwinding of the third control rope.

[0013] More preferably, the first walking mechanism and the second walking mechanism are respectively provided with rotating mechanisms capable of rotating in a circumferential direction, and the first umbrella ropes and the second umbrella ropes are connected to the rotating mechanisms.

[0014] The first control rope and the second control rope are connected to non-rotating parts of the first walking mechanism, and the third control rope is connected to a non-rotating part of the second walking mechanism.

[0015] Preferably, the first walking mechanism and the second walking mechanism are respectively provided with pulleys for walking on the main cable.

[0016] Preferably, the main cable is provided with a locking mechanism for locking the second walking mechanism.

[0017] More preferably, the second driving is provided below with a limiting and buffering mechanism for blocking the second walking mechanism.

[0018] Preferably, the inner side of the working umbrella is provided with a plurality of folding ropes in the warp direction, one end of the folding ropes is connected to the edge of the umbrella top opening, and the other end is connected to a folding rope control mechanism; the folding rope control mechanism is arranged on the main cable for controlling the folding and unfolding of the folding ropes.

[0019] More preferably, the folding rope control mechanism is connected to the first walking mechanism.

[0020] Preferably, the inner side of the working umbrella is provided with a plurality of limiting rings in the warp direction, and the folding ropes are arranged in the limiting rings.

[0021] The technical solution claimed in the present disclosure has the following beneficial effects:

[0022] 1) By fixing the driving assembly and only driving the walking mechanism to slide up and down on the partial section of the main cable, the holding force and friction force on the main cable can be greatly reduced, the wear of the main cable is reduced, and the reliability and service life of the main cable are improved.

[0023] 2) Due to the action of gravity, the second driving and the third driving only need to consume very little energy to realize the downward movement of the first walking mechanism and the second walking mechanism; the upward movement of the second walking mechanism is the result of wind force, and almost no energy is consumed by the third driving; when the first walking mechanism moves upward, the wind force will push the umbrella top to drive the first walking mechanism to move upward as the umbrella gradually opens. At the same time, the driving part and its auxiliary mechanisms such as the battery pack and other unnecessary walking parts are fixedly installed on the main cable and do not need to participate in the sliding movement. Therefore, compared with the climbing nail type or friction type walking design, the technical solution provided by the present disclosure is more energy-saving.

[0024] 3) As the first walking mechanism moves upward, a certain windward space will be formed inside the working umbrella canopy, so that the opening of the working umbrella will become very easy.

[0025] 4) The folding of the umbrella canopy when closing the umbrella is realized by the folding ropes and the folding control mechanism, which reduces the movement distance of the first walking mechanism and the second walking mechanism, and simultaneously reduces the installation distance of the first driving and the second driving, improves the reliability of control, and is beneficial to the storage of the working umbrella when it is recovered to the ground, avoiding excessive friction of the working umbrella with the ground in the free state. In addition, since the umbrella canopy will form a certain wind-catching effect when it is folded, as long as the folding rope control mechanism releases the folding ropes, the umbrella canopy can be blown open to the wind in the re-opening stage, further reducing the energy consumption required for the first driving to lift the first walking mechanism.

DETAILED DESCRIPTION

[0040] In order to make the purposes, technical solutions and beneficial effects of the embodiments in the present disclosure clearer, the technical solutions in the embodiments of the present disclosure will be described clearly and completely below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative effort belong to the protection scope of the present disclosure.

[0041] Embodiment 1

[0042] The present embodiment provides a high-altitude wind energy working system for driving fixed on-off working umbrellas. The system comprises a main cable pulled by a tethering device at a certain angle, the other end of the main cable being connected to ground working and / or power generation equipment. At least one working umbrella is installed on the main cable, the main cable passing through an orifice at the top of the working umbrella, and the working umbrella having an outer shape similar to that of a drag-type parachute.

[0043] Each working umbrella is configured with three drives, namely a first drive, a second drive and a third drive. The first drive is fixedly installed on the main cable at a proper position above the orifice at the top of the umbrella, the third drive is fixedly installed on the main cable at a proper position below the working umbrella, and the second drive is fixedly installed on the main cable at a proper position between the first drive and the third drive and offset towards the top of the umbrella.

[0044] A first walking mechanism is arranged between the first drive and the second drive, and the first walking mechanism is freely slidable up and down on the main cable through an internal pulley. The periphery of the first walking mechanism comprises a flange plate that can rotate circumferentially as a rotating mechanism, and the other ends of a plurality of first umbrella ropes evenly arranged around the orifice at the top of the umbrella are evenly attached to the flange plate. When the first walking mechanism is controlled to slide on the main cable, the top of the umbrella can be moved together.

[0045] The sliding position of the first walking mechanism is controlled by the first drive and the second drive. Exemplarily, the sliding position of the first walking mechanism is determined by a first control rope and a second control rope controlled by the first drive and the second drive, the first control rope being connected to the first drive and the first walking mechanism, and the second control rope being connected to the second drive and the first walking mechanism, the first drive and the second drive respectively controlling the winding and unwinding of the first control rope and the second control rope. When the first drive releases the first control rope and the second drive winds up the second control rope, the first walking mechanism will drive the top of the umbrella to descend; when the first drive winds up the first control rope and the second drive releases the second control rope, the first walking mechanism will drive the top of the umbrella to ascend.

[0046] A locking mechanism is fixedly installed on the main cable at an appropriate position above the third drive, and this locking mechanism can be locked or separated from the second traveling mechanism. After the second traveling mechanism is separated from the locking mechanism, it can slide freely up and down on the main cable via built-in pulleys. The second traveling mechanism includes a circumferentially rotatable flange as a rotating mechanism, and the other ends of several second parasol lines evenly distributed around the circumference of the umbrella are evenly attached to this flange. The second traveling mechanism is also connected to the third drive via a third control rope.

[0047] During the opening phase of the working parachute, the second traveling mechanism is tightly connected to the locking mechanism, transferring the tension from the second parachute rope to the locking mechanism, and then to the main cable, to drive the ground equipment to perform work or generate electricity. During the closing phase of the working parachute, the second traveling mechanism is controlled to separate from the locking mechanism, and at the same time, the third drive releases the third control rope. At this time, the second traveling mechanism will slide up the main cable a distance under the drive of the residual tension of the second parachute rope. During the reset phase, the third drive pulls the second traveling mechanism back and tightly connects it to the locking mechanism again by retrieving the third control rope.

[0048] The operation process of the high-altitude wind energy system in this embodiment can be referred to... Figures 1 to 7 :

[0049] 1) Figure 2 This demonstrates the operational system in its initial launch state or before reaching the cutoff wind speed. At this time, the tethering device 115 suspends the main cable 101 at a certain angle in the air, with at least one operational umbrella 110 and a drive system mounted on the main cable 101. The second traveling mechanism 105 and the locking mechanism 104 are locked together. The first drive 114 and the second drive 107 simultaneously control the first control rope 113 and the second control rope 108 to pull the first traveling mechanism 112 to a preset position on the main cable 101.

[0050] 2) When the tethering device raises each aerial device to the preset lower altitude limit and the wind speed reaches the cut-in wind speed, the working umbrella 110 will deploy under the wind, presenting... Figure 1 The image shows the open umbrella capturing the wind. The working umbrella 110 faces the wind and receives the force, and the huge pulling force generated by the wind energy is transmitted to the second walking mechanism 105 through several second umbrella lines 109. Then, it is transmitted to the main cable 101 through the locking mechanism 104 fixed on the main cable 101. The main cable 101 then pulls the equipment on the ground that has been switched to working and / or power generation mode to perform work or generate electricity.

[0051] 3) When the aerial work system runs to the upper limit of the altitude, the work parachute 110 will be controlled to close. The specific process is: the third drive 102 (for example, through a small winch or similar device) loosens the third control rope 103, the locking mechanism 104 loosens the buckle, at this time, the second walking mechanism 105 is driven by the second parachute rope 109 to pull the third control rope 103 along the main cable 101 upward quickly. At the same time, under the action of the wind in the air, the canopy of the work parachute 110 will be quickly folded upward and lose the ability to catch the wind. The limiting buffer mechanism 106 below the second drive 107 is used to block the second walking mechanism from colliding with the second drive 107 due to inertia. The closing instant effect is as shown in Figure 3 .

[0052] 4) Then the second drive 107 (for example, through a small winch or similar device) starts to pull the second control rope 108, and the first drive 114 (for example, through a small winch or similar device) cooperates to release the first control rope 113. The first walking mechanism 112 is pulled by the second control rope 108 to pull the work parachute 110 in the folded state along the main cable 101 downward until the top of the work parachute 110 reaches the vicinity of the second drive 107. At the same time, as the work parachute 110 loses the ability to catch the wind due to folding, the second walking mechanism 105 loses the pulling force of the second parachute rope 109 and goes downward under the action of gravity and the traction of the third control rope 103 through the third drive 102, and is locked with the locking mechanism 104 again to realize resetting. During the resetting process of the second walking mechanism 105, as the work parachute 110 continuously maintains the folded state to lose the ability to catch the wind, the ground system switches to the recovery mode, and only a small amount of energy is needed to pull the entire aerial work system back to the lower limit of the altitude through the main cable 101 to start the next ascending preparation. The specific process effect diagram is as shown in Figure 4 .

[0053] 5) When the aerial work system returns to the preset lower limit of the altitude again, the ground system stops recovering the main cable 101 and switches to the work and / or power generation mode. The first drive 114 pulls the first control rope 113 to pull the first walking mechanism 112 along the main cable 101 upward, and the second drive 107 cooperates to release the second control rope 108. As the top of the work parachute 110 is pulled along the main cable 101 upward by the first walking mechanism 112, the inside of the work parachute 110 gradually becomes a grass hat-shaped windward space and opens under the wind. At this time, the first drive 114 only needs to consume a small amount of energy to pull the first walking mechanism 112 to the preset position on the main cable 101 with the help of the wind force at the top of the canopy. The work parachute 110 also successfully completes the opening action and captures the strong aerial wind force again to transfer to the main cable 101 to drive the ground equipment to start the next work and / or power generation cycle.

[0054] In this embodiment, the first walking mechanism 112 and the second walking mechanism 105 are both provided with a circumferential rotating flange mechanism, and the first umbrella rope 111 and the second umbrella rope 109 are respectively attached to the flange mechanism. When the working umbrella 110 is unevenly stressed and rotates along the main cable 101 in the air, the circumferential rotating mechanism will help to avoid the entanglement of the umbrella ropes. Meanwhile, the first control rope 113 and the second control rope 108 are arranged in the internal non-rotating part of the first walking mechanism 112, and similarly, the third control rope 103 is arranged in the internal non-rotating part of the second walking mechanism 105. Therefore, the rotation of the working umbrella 110 will not interfere with the normal operation of the first control rope 113, the second control rope 108 and the third control rope 103. In addition, the second umbrella rope 109 can also be sequentially connected with an anti-entanglement belt to further eliminate the risk of entanglement of the second umbrella rope 109 with each air module.

[0055] Obviously, in order to improve the output power of the system, this embodiment can adopt an umbrella ladder structure, that is, a plurality of groups of working umbrellas 110 and their driving related equipment are installed on the main cable 101 at appropriate intervals, so that the working and / or power generation power can be doubled (umbrella ladder structure as shown in Figure 6 In addition, since the switch of each working umbrella 110 can be independently controlled, the switch state of each umbrella group can also be flexibly controlled according to the air wind conditions and the ground working and / or power generation demand, so as to realize the on-demand output and smooth output of power (part of the open umbrella state as shown in Figure 7

[0056] In addition, in order to realize the long endurance operation of the air working system, and the real-time confirmation of the air environment and the driving state, the system should also contain necessary energy supplement units (such as small wind turbines or solar photovoltaic panels to realize the energy supplement of various electric modules in the air), sensors for monitoring height, position, wind speed, wind direction, temperature and humidity, and necessary communication modules, etc., which will not be described here.

[0057] Embodiment 2

[0058] This embodiment provides a high-altitude wind energy working system for driving a fixed open and closed working umbrella. The system includes a main cable pulled at a certain angle by a mooring device, and the other end of the main cable is connected to ground working and / or power generation equipment. At least one working umbrella is installed on the main cable, the main cable passes through the aperture at the top of the working umbrella, and the working umbrella has a similar configuration to a resistance type parachute.

[0059] ​Each working umbrella is configured with three drives, namely a first drive, a second drive and a third drive. The first drive is fixedly installed on the main cable at a proper position above the umbrella top aperture, the third drive is fixedly installed on the main cable at a proper position below the umbrella, and the second drive is fixedly installed on the main cable at a proper position between the first drive and the third drive and offset towards the umbrella top.

[0060] A first traveling mechanism is arranged between the first drive and the second drive, and the first traveling mechanism is freely slidable up and down on the main cable through an internal pulley. The periphery of the first traveling mechanism comprises a flange plate that can rotate circumferentially as a rotating mechanism, and the other ends of a plurality of first umbrella ropes evenly arranged around the umbrella top aperture of the working umbrella are evenly attached to the flange plate. When the first traveling mechanism is controlled to slide on the main cable, the umbrella top can be moved together.

[0061] The sliding position of the first traveling mechanism is controlled by the first drive and the second drive. Exemplarily, the sliding position of the first traveling mechanism is determined by a first control rope and a second control rope controlled by the first drive and the second drive, the first control rope is connected to the first drive and the first traveling mechanism, the second control rope is connected to the second drive and the first traveling mechanism, and the first drive and the second drive control the extension and retraction of the first control rope and the second control rope respectively. When the first drive releases the first control rope and the second drive retracts the second control rope, the first traveling mechanism will drive the umbrella top to move downward; when the first drive retracts the first control rope and the second drive releases the second control rope, the first traveling mechanism will drive the umbrella top to move upward.

[0062] A locking mechanism is fixedly arranged on the main cable at a proper position above the third drive, and the locking mechanism can be locked or separated from the second traveling mechanism. The second traveling mechanism can freely slide up and down on the main cable through an internal pulley after being separated from the locking mechanism. The periphery of the second traveling mechanism comprises a flange plate that can rotate circumferentially as a rotating mechanism, and the other ends of a plurality of second umbrella ropes evenly arranged around the umbrella of the working umbrella are evenly attached to the flange plate. The second traveling mechanism is connected to the third drive through a third control rope.

[0063] During the opening stage of the working umbrella, the second traveling mechanism is tightly connected with the locking mechanism, the tension transmitted by the second umbrella ropes is transmitted to the locking mechanism, and then to the main cable, so as to pull the ground equipment to work or generate electricity; during the closing stage of the working umbrella, the second traveling mechanism is controlled to be separated from the locking mechanism, and at the same time the third drive releases the third control rope, at this time the second traveling mechanism will slide a distance along the main cable under the action of the residual tension of the second umbrella ropes; during the resetting stage, the third drive pulls the second traveling mechanism back to the locking mechanism by retracting the third control rope and tightly connecting the second traveling mechanism with the locking mechanism again.

[0064] The operation process of the high-altitude wind energy working system in the embodiment can refer to Figures 1 to 7 :

[0065] 1) Figure 2 This demonstrates the operational system in its initial launch state or before reaching the cutoff wind speed. At this time, the tethering device 115 suspends the main cable 101 at a certain angle in the air, with at least one operational umbrella 110 and a drive system mounted on the main cable 101. The second traveling mechanism 105 and the locking mechanism 104 are locked together. The first drive 114 and the second drive 107 simultaneously control the first control rope 113 and the second control rope 108 to pull the first traveling mechanism 112 to a preset position on the main cable 101.

[0066] 2) When the tethering device raises each aerial device to the preset lower altitude limit and the wind speed reaches the cut-in wind speed, the working umbrella 110 will deploy under the wind, presenting... Figure 1 The image shows the open umbrella capturing the wind. The working umbrella 110 faces the wind and receives the force, and the huge pulling force generated by the wind energy is transmitted to the second walking mechanism 105 through several second umbrella lines 109. Then, it is transmitted to the main cable 101 through the locking mechanism 104 fixed on the main cable 101. The main cable 101 then pulls the equipment on the ground that has been switched to working and / or power generation mode to perform work or generate electricity.

[0067] 3) When the aerial working system reaches its maximum altitude, the working parachute 110 will close under controlled conditions. The specific process is as follows: the third drive 102 (e.g., via a small winch or similar device) releases the third control rope 103, and the locking mechanism 104 releases its latch. At this time, the second traveling mechanism 105, driven by the tension of the second parachute rope 109, will pull the third control rope 103 rapidly upwards along the main cable 101. Simultaneously, under the influence of wind, the canopy of the working parachute 110 will rapidly fold upwards and lose its wind-catching ability. The limiting buffer mechanism 106 below the second drive 107 is used to prevent the second traveling mechanism from impacting the second drive 107 due to inertia. The effect of closing the parachute is as follows: Figure 3 As shown.

[0068] 4) Then the second drive 107 (e.g. by a small winch or similar device) starts to pull the second control rope 108, while the first drive 114 (e.g. by a small winch or similar device) cooperates to release the first control rope 113. The first walking mechanism 112, under the traction of the second control rope 108, pulls the working umbrella 110 in the folded state along the main cable 101 through the first umbrella rope 111, until the umbrella top of the working umbrella 110 reaches the vicinity of the second drive 107. At the same time, as the working umbrella 110 loses its wind catching ability due to folding, the second walking mechanism 105 loses the pulling force of the second umbrella rope 109, and under the action of gravity and the traction of the third control rope 103 by the third drive 102, it descends and locks with the locking mechanism 104 again, achieving reset. During the reset process of the second walking mechanism 105, as the working umbrella 110 continues to lose its wind catching ability due to the folded state, the ground system switches to the recovery mode, and only a small amount of energy is needed to pull the entire airborne working system back to the lower limit of the altitude through the main cable 101, to start the next preparation for ascending. The specific process effect diagram is shown in Figure 4

[0069] 5) When the airborne working system returns to the preset lower limit of the altitude again, the ground system stops recovering the main cable 101, and switches to the working and / or power generation mode. The first drive 114 pulls the first control rope 113, and drags the first walking mechanism 112 along the main cable 101 upwards, while the second drive 107 cooperates to release the second control rope 108. As the umbrella top of the working umbrella 110 is pulled upwards along the main cable 101 by the first walking mechanism 112, the inside of the working umbrella 110 gradually becomes a grass hat-shaped windward space, and opens under the wind. At this time, the first drive 114 only needs to consume a small amount of energy to pull the first walking mechanism 112 to the preset position on the main cable 101, with the help of the wind force of the umbrella top. The working umbrella 110 also successfully completes the opening action, and captures the powerful airborne wind force again, which is transmitted to the main cable 101 to drive the ground equipment to start the next working and / or power generation cycle.

[0070] ​In this embodiment, the first walking mechanism 112 and the second walking mechanism 105 are both provided with a circumferential rotating flange mechanism, and the first umbrella rope 111 and the second umbrella rope 109 are respectively tied to the flange mechanism. When the working umbrella 110 is unevenly stressed and rotates along the main cable 101 in the air, the circumferential rotating mechanism will help to avoid the entanglement of the umbrella ropes. Meanwhile, the first control rope 113 and the second control rope 108 are arranged in the internal non-rotating part of the first walking mechanism 112, and similarly, the third control rope 103 is arranged in the internal non-rotating part of the second walking mechanism 105. Therefore, the rotation of the working umbrella 110 will not interfere with the normal operation of the first control rope 113, the second control rope 108 and the third control rope 103. In addition, the second umbrella rope 109 can also be sequentially connected with an anti-entanglement belt to further eliminate the risk of entanglement of the second umbrella rope 109 with each air module.

[0071] Obviously, in order to improve the output power of the system, this embodiment can adopt an umbrella ladder structure, that is, a plurality of groups of working umbrellas 110 and their driving related equipment are installed on the main cable 101 at appropriate intervals, so that the working and / or power generation power can be doubled (umbrella ladder structure as shown in Figure 6 Obviously, in order to improve the output power of the system, this embodiment can adopt an umbrella ladder structure, that is, a plurality of groups of working umbrellas 110 and their driving related equipment are installed on the main cable 101 at appropriate intervals, so that the working and / or power generation power can be doubled (umbrella ladder structure as shown in Figure 7 Obviously, in order to improve the output power of the system, this embodiment can adopt an umbrella ladder structure, that is, a plurality of groups of working umbrellas 110 and their driving related equipment are installed on the main cable 101 at appropriate intervals, so that the working and / or power generation power can be doubled (umbrella ladder structure as shown in

[0072] In a more preferred scheme, in order to reduce the running distance of the first control rope 113 and the second control rope 108 as much as possible, facilitate the storage of the working umbrella 110 when it is recovered to the ground, and avoid excessive friction with the ground in the free state, a folding rope control mechanism 116 can also be bound on the first walking mechanism 112, and a plurality of folding ropes 117 (at least 4) are evenly installed along the warp direction inside the umbrella surface to realize the folding control of the umbrella surface when the umbrella is closed.

[0073] Figure 8 The installation position of the folding rope control mechanism 116 is shown in the schematic diagram. The folding rope control mechanism is preferably bound with the first walking mechanism 112, and can realize synchronous sliding on the main cable 101 with the first walking mechanism 112.

[0074] Figure 9 The setting of the folding rope 117 is shown in the schematic diagram, wherein Figure 9 (a) is the effect before folding, Figure 9(b) is the effect after folding (8 folding ropes). One end of the folding rope 117 is fixed to the opening edge of the umbrella top of the working umbrella 110, and then sequentially passes through several limiting rings along the inner side meridian of the working umbrella 110, and finally is connected to the folding rope control mechanism 116. The folding rope control mechanism 116 (which can be a small winch or the like) can simultaneously tighten or release all folding ropes 117. From Figure 9 (b) As can be seen, after the folding treatment of the umbrella surface, the windward area (or projected area) of the umbrella cloth is greatly reduced, which is very beneficial for storage.

[0075] In the present embodiment, by using the folding rope control mechanism 116, the movement distance of the first walking mechanism 112 can also be reduced, and the reliability of control can be improved. As shown in Figure 10 As shown in the figure, at the uppermost altitude, immediately after the working umbrella 110 is folded by the wind, the folding rope control mechanism 116 is started to fold the umbrella surface, at this time the second umbrella rope 109 almost recovers a distance of about one radius of the working umbrella 110 in advance, so that the second walking mechanism 105 can be synchronized to descend a distance of about one radius of the working umbrella 110. Therefore, the distance that the first walking mechanism 112 originally needs to descend is also reduced synchronously, that is, the repositioning connection of the second walking mechanism 105 and the locking mechanism 104 can be realized. Moreover, the lengths of the second control rope 108 and the first control rope 113 are synchronously reduced, and the installation distances of the first drive 114 and the second drive 107 are also synchronously shortened. This is extremely beneficial to improve the reliability of system operation. In addition, since the umbrella surface will form a certain wind-catching effect when it is folded, during the re-opening of the umbrella, as long as the folding rope control mechanism 116 releases the folding rope 117, the umbrella surface can be blown open to the wind, further reducing the energy consumption required for the first drive 114 to pull up the first walking mechanism 112.

[0076] In addition, in order to realize long endurance operation of the aerial working system, and real-time confirmation of the aerial environment and the driving state, etc., the system should also include necessary energy supplement units (such as small wind turbines or solar photovoltaic panels to realize the energy supplement of various electrical modules in the air), sensors for monitoring height, position, wind speed, wind direction, temperature and humidity, etc., and necessary communication modules, etc., which will not be described here.

[0077] The above-described embodiments and application examples are only exemplary descriptions of the present disclosure, and do not limit the scope of the present disclosure. Without departing from the design spirit of the present disclosure, various modifications and improvements of the technical solutions of the present disclosure made by those skilled in the art should fall within the protection scope of the present disclosure.
