Description

TECHNICAL FIELD

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

[0002] In the umbrella or sail type high-altitude wind energy system, the wind force received by the umbrella or sail as the windward surface needs to be transmitted to the lower driving member through several vice ropes attached around the umbrella or sail, and then transmitted to the main cable through the lower driving docking base fixed on the main cable connected with the lower driving member. When the windward surface rises to the preset upper limit altitude, the lower driving member needs to be immediately separated from the fixed base and quickly ascend under the driving of the vice rope tension, so that the windward surface is folded upward along the wind direction, thereby losing the wind catching ability. At this time, the ground equipment only needs to consume less energy to pull the aerial system back to the preset lower limit altitude. When the lower driving member is connected with the docking base again, the windward surface is opened again, entering the next working cycle.

[0003] In the existing scheme, the connection and separation of the lower driving member and the docking base often use a lock tongue mechanism. By controlling the extension and retraction of several lock tongues on the lower driving member, the connection and separation of the lower driving member and the docking base in the buckle position are realized. In the separation process, the thin tongue tip needs to bear the same huge tension transmitted by the vice rope as the relatively thick structure at the rear end, so that the lock tongue and the base are buckled tightly. This poses a huge challenge to the mechanical strength of the tongue tip part, and the tongue tip position is at risk of collapse before separation. CONTENT OF THE UTILITY MODEL

DETAILED DESCRIPTION

[0039] 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 with reference to 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 work fall within the protection scope of the present disclosure.

[0040] Embodiment

[0041] The embodiment provides a driving docking mechanism of a high-altitude wind energy working system.

[0042] The driving in the embodiment comprises a base and a lower driving part, and the base is fixed on a main cable of the high-altitude wind energy working system. The lower driving part is connected to a peripheral edge of a windward surface of the high-altitude wind energy working system through a plurality of auxiliary ropes, and can walk up and down along the main cable under an instruction.

[0043] The base and the lower driving part are respectively provided with a first docking part and a second docking part, the first docking part and the second docking part are respectively provided with a hook-shaped first docking groove and a hook-shaped second docking groove, and the first docking groove and the second docking groove are oppositely arranged. The docking mechanism is provided with a control module for controlling locking or unlocking of the first docking groove and the second docking groove, so as to control locking or unlocking between the lower driving part and the base.

[0044] The embodiment adopts the hook-shaped upper and lower docking parts to realize locking and unlocking between the lower driving part and the base, so that local stress of the stress part of the docking part in the separation process can be avoided, and the safety performance and unlocking efficiency of the component can be effectively improved.

[0045] In a preferred scheme, the lower driving part and the base are respectively provided with a first shaft and a second shaft, the first docking part and the second docking part are respectively rotated about the first shaft and the second shaft under stress to realize mutual buckling or mutual moving away of the first docking part and the second docking part.

[0046] In a more preferred scheme, the lower driving part is provided with a first limiting part for limiting rotation of the first connecting part, the base is provided with a second limiting part for limiting rotation of the second connecting part, and the first limiting part and the second limiting part are respectively connected to the control module.

[0047] In the example, the lower driving member and the base are respectively provided with a first cam and a second cam, the first cam and the second cam are respectively connected with a first clamping bolt and a second clamping bolt, and the first abutting member and the second abutting member are respectively provided with a first limiting slot and a second limiting slot. Rotation of the first cam and the second cam respectively drives the first clamping bolt and the second clamping bolt to fall into or move away from the first limiting slot and the second limiting slot, so as to realize locking or unlocking between the lower driving member and the base. The lower driving member and the base are respectively provided with a first motor and a second motor for driving the first cam and the second cam to rotate, and a first solar module and a second solar module for supplying power to the first motor and the second motor.

[0048] In a more preferred scheme, the lower driving member is provided with a plurality of first abutting members, the base is provided with a plurality of second abutting members corresponding to the first abutting members, and the first cam and the second cam are respectively connected with a corresponding number of first clamping bolts and second clamping bolts.

[0049] The embodiment adopts a cam to control automatic unlocking between the first abutting member and the second abutting member, and one cam can drive synchronous separation and synchronous locking of multiple groups of abutting members, thereby increasing the firmness of the connection between the lower driving member and the base and the convenience of unlocking. In addition, the driving abutting mechanism only needs to consume a small amount of energy to drive the cam mechanism to rotate when the first abutting member and the second abutting member are locked and unlocked, and almost no energy is consumed at other times. Therefore, long-term endurance of the driving abutting mechanism can be realized by the self-provided solar energy supplement device combined with the energy storage battery.

[0050] In a preferred scheme, the abutting mechanism includes a first guide module for guiding the locking process of the lower driving member and the base. In an example structure, the first guide module includes a guide rod connected with the lower driving member and a guide sleeve connected with the base. When the lower driving member approaches the base, the guide rod enters the guide sleeve to make the lower driving member and the base coaxial.

[0051] In a more preferred scheme, the abutting member further includes a second guide module for guiding the locking process of the lower driving member and the base. In an example structure, the second guide module includes a first guide cylinder surrounding the guide rod and a second guide cylinder surrounding the guide sleeve, the first abutting member is arranged in the first guide cylinder, and the second abutting member is arranged in the second guide cylinder. When the lower driving member approaches the base, the first guide cylinder slides downward along the outer surface of the second guide cylinder.

[0052] The outer sides of the first guide cylinder and the second guide cylinder are respectively provided with first alignment members and second alignment members with concave-convex structures, the convex parts / concave parts of the first alignment members correspond to the concave parts / convex parts of the second alignment members, and the number of the concave parts and the convex parts of the first alignment members and the second alignment members respectively corresponds to the number of the first alignment members and the second alignment members. The concave parts and the convex parts on the first alignment members and the second alignment members can automatically correct the relative rotation deviation of the lower driving member and the base in the circumferential direction, and realize accurate alignment in the circumferential direction.

[0053] The locking and unlocking processes of the driving docking mechanism in the embodiment are as follows:

[0054] 1) When the lower driving member approaches the base, the guide rod enters the guide sleeve inside the base first, so as to ensure that the lower driving member and the base are coaxial. Then the first guide cylinder and the second guide cylinder are buckled with each other, and the first guide cylinder is sleeved on the second guide cylinder. Even if there is a rotation deviation of the lower driving member and the base in the circumferential direction, it can be automatically corrected by the first alignment members and the second alignment members with the concave-convex structure, and accurate alignment in the circumferential direction is realized;

[0055] 2) When the lower driving member and the base further approach, the first alignment members inside the lower driving member and the second alignment members inside the base will contact and push and rotate each other, realizing the buckling effect of the Jan type coupler. At this time, the first cam motor and the second cam motor respectively control the rotation alignment of the first cam and the second cam, so as to ensure that the first clamping bolt and the second clamping bolt are accurately buckled into the limiting grooves in the corresponding positions of the first alignment members and the second alignment members respectively, realizing the locking of the first alignment members and the second alignment members;

[0056] 3) The whole aerial working system is pulled together to the high altitude direction under the traction of the windward surface and the mooring device, and drives the ground equipment to work and generates electricity, until reaching the preset upper limit of the altitude;

[0057] 4) When the aerial system reaches the preset upper limit of the altitude, the first clamping bolt and the second clamping bolt are lifted by the respective cams, and the first clamping bolt and the second clamping bolt respectively leave the limiting grooves of the first alignment members and the second alignment members, so that the first alignment members and the second alignment members are in the unlocked state, and the lower driving member and the base are separated.

[0058] In the embodiment, the design of the first guide module, the second guide module and the alignment members with the concave-convex structure enables accurate alignment of the docking process of the lower driving member and the base, and automatically corrects the angle deviation caused by the rotation of the driving on the main cable, ensuring efficient and reliable connection of the lower driving member and the base.

[0059] Application example

[0060] The following takes the umbrella-shaped high-altitude wind energy system as an example to further clarify the driving docking mechanism of the high-altitude wind energy system in the present disclosure.

[0061] Figure 1 a shows the basic composition of one of the working units of the high-altitude wind energy system. The working unit includes a main cable 100 pulled by a high-altitude tethering device, the other end of the main cable 100 is connected to a ground working or power generation device, and other aerial devices are installed on the main cable 100. The working unit also includes a windward surface 300, an upper driving member 200, a lower driving combination 500, and a plurality of first auxiliary umbrella ropes 400, etc.

[0062] Among them, one end of the first auxiliary umbrella rope 400 is evenly attached to the outer edge of the windward surface, and the other end is attached to the lower driving combination 500. The top center of the windward surface 300 usually has a hole of appropriate size, called "orifice". The main function of the orifice is that when the windward surface 300 is opened, the internal air can flow out of the orifice smoothly, thereby reducing the violent swinging of the windward surface in the air.

[0063] The upper driving member 200 is installed on the main cable 100 at the central position of the orifice and can walk up and down along the main cable 100 when receiving instructions from the ground control system. The orifice is attached to the upper driving member 200 by a plurality of second auxiliary umbrella ropes. When the upper driving member 200 walks up and down, it can adjust the shape of the windward surface 300. The lower driving combination 500 includes a lower driving member 510 that can walk up and down on the main cable 100 and a base 520 that is fastened to the main cable 100.

[0064] Figure 1 a shows the state of the windward surface 300 when it is unfolded and working. At this time, the lower driving member 510 is closely connected with the base 520. The huge pulling force transmitted from the first auxiliary umbrella rope 400 is transmitted to the base 520 through the lower driving member 510, and then transmitted to the main cable 100 by the base 520. The entire aerial working system is pulled together with the main cable 100 to move in the high-altitude direction under the traction of the windward surface 300 and the tethering device, and drives the ground equipment to work and generate power, until reaching the preset upper limit altitude.

[0065] Figure 1b shows the closing state of the windward surface 300. When the aerial system reaches the upper limit of the preset altitude, the instruction to close the windward surface 300 is received, and the lower driving part 510 is immediately separated from the base 520 according to the instruction, and driven upward to a certain height by the pulling force of the first auxiliary umbrella rope 400. At this time, the windward surface 300 is quickly folded upward under the action of high-altitude wind force, and loses the ability to catch wind. At this time, the ground equipment only needs to consume a little energy to pull the aerial system back to the lower limit of the preset altitude. Then, under the cooperation of the downward movement of the upper driving part 200, the lower driving part 510 will also move downward and be connected with the base 520 again, and then the upper driving part 200 moves upward to the preset position, and the windward surface 300 will be unfolded again under the action of high-altitude wind force.

[0066] Since the braking capacity of the lower driving part 510 on the main cable 100 is limited, it cannot directly transmit the huge pulling force generated by the first auxiliary umbrella rope 400 to the main cable 100, and must be safely transmitted to the main cable 100 through the base 520 fastened on the main cable 100. Therefore, the reliable connection and separation of the lower driving part 510 and the base 520 are crucial for the smooth work and recovery of the high-altitude wind energy work system. In the traditional design, a lock tongue mechanism is generally used to realize the locking and separation of the lower driving part 510 and the base 520, but the lock tongue mechanism is always subjected to the huge force transmitted from the first auxiliary umbrella rope 400 before complete separation, so that the lock tongue is tightly buckled with the base, which not only may cause difficulty in opening the lock tongue, but also may cause wear or collapse of the lock tongue tip during the separation process.

[0067] Figure 2 The driving docking mechanism in the application example is shown. In the application example, the lower driving part 510 mainly includes a first solar power generation and energy storage module 511, a first outer guide 512, an inner guide rod 514, and a rotating part 515 for tying the first auxiliary umbrella rope 400, etc. The base 520 is fixed on the preset position of the main cable 100, and mainly includes a second solar power generation and energy storage module 521, a second outer guide 522, and a second docking module 523, etc. There is also a set of first docking module 513 corresponding to the second docking module 523 in the lower driving part 510. Figure 2 a shows the state when the lower driving part 510 is separated from the base 520, Figure 2 b shows the state when the lower driving part 510 is connected with the base 520.

[0068] Figure 3 shows a schematic diagram of the structure of the driving docking mechanism in the present application, to more clearly illustrate the working principle of the driving docking mechanism. As shown, the main connecting components are the hook-shaped first docking piece 5132 and the hook-shaped second docking piece 5232, which adopt the structure and working principle of a Janus coupler, and rotate around the first rotating shaft 5131 and the second rotating shaft 5231 respectively, which are arranged inside the lower driving member 510 and the base 520 respectively.

[0069] The lower driving member 510 and the base 520 are also respectively provided with the first clamping bolt 5134 and the second clamping bolt 5234, which are respectively used to lock the first docking piece 5132 and the second docking piece 5232. Specifically, when the first docking piece 5132 and the second docking piece 5232 approach each other and automatically engage, the first clamping bolt 5134 and the second clamping bolt 5234 automatically engage into the grooves in the corresponding positions of the first docking piece 5132 and the second docking piece 5232 to limit their rotation, lock the set of connecting hooks, and prevent unhooking.

[0070] In the preferred scheme, the first clamping bolt 5134 and the second clamping bolt 5234 are respectively controlled by the first cam 5136 and the second cam 5236. The first cam 5136 and the second cam 5236 cooperate with the first spring 5133 on the head of the first clamping bolt 5134 and the second spring 5233 on the head of the second clamping bolt 5234 respectively, to control the stroke of the first clamping bolt 5134 and the second clamping bolt 5234, thereby achieving the locking and unlocking of the first docking piece 5132 and the second docking piece 5232. The other ends of the first spring 5133 and the second spring 5233 are respectively abutted against the inner walls of the first outer guide 512 and the second outer guide 522, to apply a spring force to the clamping bolts. When the first docking piece 5132 and the second docking piece 5232 are docked, the clamping bolts are clamped on the two docking pieces by the spring force.

[0071] The rotation of the first cam 5136 and the second cam 5236 is respectively controlled by the first cam motor 5135 and the second cam motor 5235, to synchronously achieve the synchronous lifting of the first clamping bolt 5134 and the second clamping bolt 5234, thereby achieving the unlocking of the first docking piece and the second docking piece, and the synchronous falling of the first clamping bolt 5134 and the second clamping bolt 5234, thereby achieving the locking of the first docking piece and the second docking piece. The first solar power generation and energy storage module 511 and the second solar power generation and energy storage module 521 respectively supply power to the first cam motor 5135 and the second cam motor 5235.

[0072] When the first and second latches 5134 and 5234 are lifted by the respective cams, the first and second latches 5134 and 5234 respectively leave the limiting grooves of the first and second abutments 5132 and 5232, so that the first and second abutments 5132 and 5232 are in an unlocked state. At this time, the lower driving member 510 is rapidly separated from the base 520 under the driving of the first sub-umbrella rope 400. Figure 3b The unlocked and separated state of the first and second abutments 5132 and 5232 is shown. At the same time, the first and second springs 5133 and 5233 are compressed and store a certain elastic potential energy, which is respectively applied to the first and second latches 5134 and 5234.

[0073] In the present application example, first and second guide modules are further provided to assist the abutment of the lower driving member and the base. The first guide module is composed of an inner guide rod 514 provided in the lower driving member and a guide sleeve provided in the base, and the second guide module is composed of a cylindrical first outer guide member 512 provided in the lower driving member and a cylindrical second outer guide member 522 provided in the base. Specifically, when the lower driving member 510 approaches the base 520, the inner guide rod 514 will first enter the guide sleeve inside the base 520, so as to ensure that the lower driving member 510 and the base 520 are in a coaxial state. Then the first outer guide member 512 and the second outer guide member 522 are mutually buckled, wherein the inner cylinder of the first outer guide member 512 has a slightly larger inner diameter than the outer diameter of the inner cylinder of the second outer guide member 522, and when the two are in a coaxial state, the inner cylinder of the first outer guide member 512 will be sleeved on the inner cylinder of the second outer guide member 522.

[0074] In a preferred scheme, the outer sides of the first and second outer guide members 512 and 522 are respectively provided with first and second alignment members, which have concave-convex configurations, and the convex / concave part of the first alignment member corresponds to the concave / convex part of the second alignment member. Exemplarily, the first and second alignment members are in the form of V-shaped alignment grooves, so that even if the lower driving member 510 and the base 520 have a circumferential rotation deviation, it will be automatically corrected by the V-shaped alignment grooves, achieving precise alignment in the circumferential direction.

[0075] When the lower driving member 510 is coaxial with the base 520, the lower driving member continues to move downward and further approaches the base 520, at this time, the first docking member 5132 inside the lower driving member 510 and the rear part of the second docking member 5232 inside the base 520 will contact and push each other and rotate, realizing the buckling effect of the Jan coupler. At this time, the first cam motor 5135 and the second cam motor 5235 control the rotation of the first cam 5136 and the second cam 5236, respectively, and under the action of the elastic potential energy stored in the first spring 5133 and the second spring 5233, the first clamping bolt 5134 and the second clamping bolt 5234 are precisely buckled into the corresponding position of the first docking member 5132 and the second docking member 5232., realizing the locking of the first docking member 5132 and the second docking member 5232. The first spring 5133 and the second spring 5233 can also prevent the first clamping bolt 5134 and the second clamping bolt 5234 from being uncontrolled from the corresponding clamping position.

[0076] The first docking module 513 and the second docking module 523 are respectively installed inside the first outer guide 512 and the second outer guide 522, and the specific installation method is not limited, and FIG. 4 only shows an exemplary installation method of some main components. Figure 4a As shown in FIG. 4, the first rotating shaft 5131 is installed inside the housing of the first outer guide 512, and the first docking member 5132 can rotate freely around it during the connection and separation process. Figure 4b As shown in FIG. 4, the second rotating shaft 5231 is installed inside the housing of the second outer guide 522, and the second docking member 5232 can rotate freely around it during the connection and separation process.

[0077] In the preferred scheme, according to the design needs, the first docking module 513 and the second docking module 523 can be provided with multiple groups of docking members. For example, it is generally designed to be 3 groups or 4 groups of first docking members and second docking members, and the first cam 5136 and the second cam 5236 are also designed to be able to drive the corresponding number of clamping bolts, that is, 3 convex 3 concave or 4 convex 4 concave, to ensure that each group of clamping bolts realizes the synchronous locking and unlocking of each docking member. At the same time, the V-shaped alignment sliding groove on the outside of the first outer guide 512 and the second outer guide 522 should also be designed in the same number to ensure the accurate alignment of each group of docking mechanisms. FIG. 5 shows a structural schematic diagram of a docking mechanism with 4 groups of docking members, wherein Figure 5a is a state diagram when the first and second docking members are locked, Figure 5b is a state diagram when the first and second docking members are separated.

[0078] It is emphasized that each first docking member in the first docking module 513 has the same structural design and is arranged along the first cam in a uniform manner, and each second docking member in the second docking module 523 also has the same shape design and is arranged along the second cam in a uniform manner, so the docking relationship of the first docking member and the second docking member does not need to be one-to-one correspondence. For example, the first docking module 513 has three first docking members ABC, and the second docking module 523 has three second docking members XYZ, and the docking relationship of each group of docking members can be A-X, B-Y, and C-Z, or can be staggered as A-Z, B-X, and C-Y, or can be A-Y, B-Z, and C-X. The matching relationship of the first docking member and the second docking member is determined by the relative rotation angle when the lower driving member 510 and the base 520 approach, and is combined and matched after the V-shaped alignment slot on the outside of the first outer guide 512 and the second outer guide 522 is automatically aligned.

[0079] The main energy consumption in the application example comes from the rotation driving of the first cam 5136 and the second cam 5236 by the first cam motor 5135 and the second cam motor 5235. Since the application example adopts a one-to-many mode, that is, one cam synchronously drives all the locking pins, the driving docking mechanism in the application example only needs two cam motors in total, one of which is arranged in the lower driving member 510 and the other of which is arranged in the base 520. At the same time, in the actual operation process, the opening and closing frequency of the lower driving member 510 and the base 520 is low, so the requirement for electric energy is not high, and the power supply and the requirement for endurance can be completely realized by the first solar power generation and energy storage module 511 and the second solar power generation and energy storage module 521 respectively.

[0080] Similar to the existing air working system, the air working system in the application example also has a height sensor, a GPS, a wind speed sensor, a wind direction sensor, etc. in communication connection with the ground control system, and the setting and control of these devices can refer to any existing high-altitude wind energy working system. In addition, the upper driving and the lower driving can also use any existing walking device, which will not be described here.

[0081] The driving docking mechanism in the application example adopts the basic principle of Jan-type coupler, which can avoid local stress of the stress part of the docking mechanism during separation, effectively improve the safety performance of the components and the unlocking efficiency of the lower driving member and the base. The automatic unlocking device with cam mechanism not only enables the synchronous separation and synchronous locking of multiple groups of docking members, but also increases the firmness of the connection between the lower driving member and the base and the convenience of unlocking.

[0082] The design of the first guide module, the second guide module and the V-shaped alignment sliding groove enables accurate alignment of the lower driving member and the base during the docking process, and can automatically correct the angle deviation caused by the rotation of the driving on the main cable, ensuring efficient and reliable connection of the lower driving member and the base. In addition, the driving docking mechanism only needs to consume a small amount of energy to drive the cam mechanism to rotate when the first docking member and the second docking member are locked and unlocked, and almost no energy is consumed at other times, so the long-term endurance of the driving docking mechanism can be realized through the self-provided solar energy supplementing device combined with the energy storage battery.

[0083] 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 to the technical solutions of the present disclosure made by those skilled in the art shall fall within the scope of protection of the present disclosure.
