Technical Field

The invention relates to the field of high-altitude wind energy, in particular to a winding umbrella-shaped wind energy opening and closing method, a winding umbrella-shaped wind energy conversion device and a power generation system.

Background

The high-altitude wind energy is a renewable clean energy source with wide distribution and rich reserves. Studies have indicated that: the wind energy at high altitude is proportional to the cube of the wind speed, and in general, the wind speed is increased by 1 time and the wind energy is increased by 8 times, so that the wind energy at high altitude can be tens of times or even hundreds of times higher than the wind energy at ground level. In the ideal high-altitude position, the theoretical power generation time of high-altitude wind power can reach 95% of annual time, the annual power generation time is more than 8200 hours, and the annual power generation time of the low-power 10 megawatt high-altitude wind power generation system is more than 5000 hours. Therefore, the high-altitude wind power generation has the advantages of high average energy density, wide regional distribution, high stability, low unit cost and the like.

One common type of high altitude wind power generation system includes an umbrella-type wind energy conversion device (or a high altitude kite), a main cable, a hoist, and a generator. The umbrella-shaped wind energy conversion device is opened in the air and kept stable, the main cable is lifted and pulled under the action of high-altitude wind power, and when the main cable is pulled up, the winch on the ground is driven to rotate, so that the generator is driven to generate electricity, and the process that wind energy is converted into mechanical energy and the mechanical energy is converted into electric energy is realized. The umbrella-shaped wind energy conversion device is required to be closed after rising to the ending height, then the main cable is wound by the winding machine, the umbrella-shaped wind energy conversion device is pulled to descend to the starting height, and then the wind energy conversion device is opened in the air again, and the next round of power generation process is carried out, so that the wind energy conversion device reciprocates. Reference is made in particular to the Chinese patent CN 102220938B-umbrella type wind power plant and wind power system.

The umbrella-shaped wind energy conversion device needs to be repeatedly opened and closed, and a simple, efficient and reliable opening and closing mode is particularly important. Chinese patent CN 106523273B-a double-driving umbrella type wind energy conversion device and its opening and closing method, the device comprises: a cable; a stop fixed to the cable; an umbrella body with the top center sleeved on the cable; the first driver is connected with the center of the top of the umbrella body; a second driver located between the stop and the first driver; the second driver is connected with the umbrella body through an umbrella rope, and the umbrella rope is connected with the edge of the umbrella body; the second driver and/or the stop are provided with a locking mechanism which can lock the second driver and the stop. The scheme mainly adopts two drivers to move back and forth on the mooring rope to realize the opening and closing of the umbrella-shaped wind energy conversion device, the opening and closing process of the umbrella body can be realized by only a few actions, and the wind force effect is utilized in the opening and closing process, so that the electric energy consumption of the drivers is greatly reduced. Similarly, there is chinese patent CN 106523274B-a single-drive umbrella-type wind energy conversion device and its opening and closing method. Since the drive of the above solution needs to be moved back and forth on the cable and kept stationary, there is a high demand for reliability of the drive construction and high demands for strength and wear resistance of the cable.

in the ascending stage, the high-altitude wind energy drives the acting umbrella to ascend, the first cable and the second cable are used for paying off, the first cable pulls the first winding drum to rotate, and the second cable pulls the second winding drum to rotate; the acting umbrella is stopped after being lifted to a certain height;

in the umbrella closing stage, the acting umbrella continues to ascend to a first height, the first cable keeps releasing the ropes, the second cable stops releasing the ropes, the umbrella cover edge of the acting umbrella continues to ascend and turns upwards, and the acting umbrella is closed;

in the descending stage, the motor drives the first winding drum and the second winding drum to rotate simultaneously, the first cable and the second cable are wound, the first winding drum winds the first cable, the second winding drum winds the second cable, and the first cable and the second cable pull the acting umbrella to descend; the acting umbrella is stopped after being lowered to a certain height;

In the stage of opening the umbrella, the acting umbrella continuously descends to a second height, the first cable keeps the rope to be retracted, the second cable stops the rope to be retracted, the edge of the umbrella cover of the acting umbrella continuously descends and turns down, and the acting umbrella is opened;

the first cable can be released after the locking state is released.

The winch umbrella-type wind energy opening and closing method is suitable for the high-altitude wind energy power generation system in the ground power generation mode, and the first winding drum, the second winding drum and the motor are all fixed on the main cable. The acting umbrella is pulled by the first cable and the second cable to control the opening and closing of the umbrella. After the acting umbrella is unfolded in the air and kept stable, the main cable can be pulled to ascend, so that the ground generator set is driven to generate electricity. The opening and closing method of the scheme specifically comprises the following stages:

in the ascending stage, wind power drives the acting umbrella to ascend, the first cable is unlocked to release the rope, and the acting umbrella pulls the first cable and the second cable to ascend; the first cable pulls the first drum to rotate and the second cable pulls the second drum to rotate. After the acting umbrella rises to a certain height, the first cable is locked to release the rope, the acting umbrella is tensioned by the first cable, and the acting umbrella stops rising. At this time, the acting umbrella can be opened in the air and kept stable, and a signal for opening the umbrella can be sent outwards.

And in the umbrella closing stage, after receiving an umbrella closing signal, unlocking the first cable to release the rope, and continuously lifting the wind driven acting umbrella to a first height. The second winding drum stops rotating, the second mooring rope stops releasing the ropes and tightens the top of the umbrella cover of the acting umbrella; the edge of the umbrella cover of the wind driven acting umbrella continues to ascend and turn upwards, the first cable keeps releasing the rope, and the first winding drum keeps rotating until the acting umbrella is closed. After the acting umbrella is closed, the first mooring rope is locked to be released.

In the descending stage, the motor is started and drives the first winding drum and the second winding drum to rotate simultaneously, the first winding drum winds the first cable, and the second winding drum winds the second cable; the first cable and the second cable pull the closed acting umbrella to descend. After the acting umbrella descends to a certain height, the motor is closed, the first cable and the second cable stop winding ropes, and the acting umbrella stops descending. At this time, the acting umbrella can close the umbrella in the air, and can send out a signal for closing the umbrella.

And in the umbrella opening stage, after receiving an umbrella opening signal, the motor is started again, and the first cable and the second cable simultaneously pull the closed acting umbrella to continuously descend to the second height. The second winding drum stops rotating, the second cable stops winding up, and the wind power drives the top of the umbrella cover of the acting umbrella to move upwards; meanwhile, the motor keeps driving the first winding drum to rotate, the first cable keeps taking up the rope and pulls the edge of the umbrella cover of the acting umbrella to continuously descend and fold down, and the acting umbrella is opened.

Therefore, the locking mechanism can be designed into a one-way locking mode, namely, the locking mechanism locks the rope in a locking state, allows the rope to be retracted, and allows the rope to be released and retracted in an unlocking state.

As shown in fig. 1 to 6, in the present technical solution, in a windlass umbrella type wind energy opening and closing method, one end of a first cable 21 is winded on a first drum 120, and the other end is tied on the edge of the umbrella cover of a working umbrella 10; one end of the second cable 22 is wound on the second drum 130, and the other end is tied on the top of the umbrella surface of the acting umbrella 10; comprising the following stages:

In the ascending stage, the high-altitude wind energy drives the acting umbrella 10 to ascend, the first cable 21 and the second cable 22 are used for paying out, the first cable 21 pulls the first drum 120 to rotate, and the second cable 22 pulls the second drum 130 to rotate; the working umbrella 10 is stopped after being lifted to a certain height;

in the umbrella closing stage, the acting umbrella 10 continues to ascend to the first height H1, the first cable 21 keeps releasing the ropes, the second cable 22 stops releasing the ropes, the edge of the umbrella cover of the acting umbrella 10 continues to ascend and turns upwards, and the acting umbrella 10 is closed;

in the descending stage, the motor drives the first drum 120 and the second drum 130 to rotate simultaneously, the first cable 21 and the second cable 22 are wound up, the first drum 120 winds up the first cable 21, the second drum 130 winds up the second cable 22, and the first cable 21 and the second cable 22 pull the acting umbrella 10 to descend; the working umbrella 10 is stopped after being lowered to a certain height;

in the stage of opening the umbrella, the acting umbrella 10 continues to descend to the second height H2, the first cable 21 keeps the rope folding, the second cable 22 stops the rope folding, the edge of the umbrella cover of the acting umbrella 10 continues to descend and turns downwards, and the acting umbrella 10 is opened;

the first cable 21 needs to be unlocked to release the rope.

The winch umbrella type wind energy opening and closing method is suitable for the above-mentioned high altitude wind energy generating system in the ground generating mode, and the first winding drum 120, the second winding drum 130 and the motor are all fixed on the main cable 20. The work umbrella 10 is opened and closed by traction control of a first cable 21 and a second cable 22. After the umbrella 10 is opened in the air and kept stable, the main cable 20 can be pulled to rise, so that the ground generator set is driven to generate electricity. The opening and closing method of the scheme specifically comprises the following stages:

In the ascending stage, wind power drives the acting umbrella 10 to ascend, the first cable 21 is unlocked to release the rope, and the acting umbrella 10 pulls the first cable 21 and the second cable 22 to ascend; the first cable 21 pulls the first drum 120 to rotate and the second cable 22 pulls the second drum 130 to rotate. After the acting umbrella 10 rises to a certain height, the first cable 21 is locked to be released, the acting umbrella 10 is tensioned by the first cable 21, and the acting umbrella 10 stops rising. At this time, the working umbrella 10 is opened in the air and kept stable, and can send out a signal for opening the umbrella.

In the umbrella closing stage, after receiving an umbrella closing signal, the first cable 21 is unlocked, the rope is released, and the wind power driven acting umbrella 10 continues to ascend to the first height H1. The second drum 130 stops rotating, the second cable 22 stops paying out and tightens the top of the canopy of the work umbrella 10; the edge of the umbrella cover of the wind driven acting umbrella 10 continues to rise and fold upwards, the first cable 21 keeps the rope unreeling, and the first drum 120 keeps rotating until the acting umbrella 10 is closed. After the acting umbrella 10 is closed, the first cable 21 is locked to be released.

In the descending stage, the motor is started to drive the first drum 120 and the second drum 130 to rotate simultaneously, the first drum 120 winds the first cable 21, and the second drum 130 winds the second cable 22; the first cable 21 and the second cable 22 simultaneously pull the closed acting umbrella 10 to descend. After the working umbrella 10 descends to a certain height, the motor is turned off, the first cable 21 and the second cable 22 stop winding up the ropes, and the working umbrella 10 stops descending. At this time, the working umbrella 10 can close the umbrella in the air, and can send out a signal for closing the umbrella.

In the umbrella opening stage, after receiving an umbrella opening signal, the motor is started again, and the first cable 21 and the second cable 22 simultaneously pull the closed acting umbrella 10 to continuously descend to the second height H2. The second drum 130 stops rotating, the second cable 22 stops winding up, and the wind force drives the top of the umbrella cover of the acting umbrella 10 to move upwards; at the same time, the motor keeps driving the first drum 120 to rotate, the first cable 21 keeps taking up the ropes and pulls the edge of the umbrella cover of the acting umbrella 10 to continuously descend and fold down, and the acting umbrella 10 is opened completely. After the umbrella 10 is opened, the motor is turned off, the first drum 120 stops rotating, and the first cable 21 stops winding.

According to the scheme, the acting umbrella 10 is opened and closed under the action of wind force by utilizing the combination of the traditional winding drum and the traditional motor through differentiated rope collecting time and rope releasing time between a first cable 21 positioned at the edge of the umbrella cover and a second cable 22 positioned at the top of the umbrella cover; the working umbrella 10 can keep the state of opening and closing the umbrella by timely locking the rope releasing of the first rope 21; and further solves the opening and closing problems of the umbrella-shaped wind energy conversion device, and achieves the effects of simplicity, high efficiency and reliability.

Preferably, the device further comprises a locking mechanism 50, and in the locked state, the first cable 21 can only be retracted; in the unlocked state, the first cable 21 is capable of winding and unwinding. The first cable 21 can be released after the locking mechanism 50 is used for realizing the scheme. As can be seen from the four stages described above, the first cable 21 only needs to be locked and released, and no locking and retraction of the rope is required. Thus, locking mechanism 50 may be configured as a one-way lock, i.e., locking the payout, allowing payout, and unlocking the payout. Compared with the bidirectional locking mode, when the first cable 21 is retracted, the locking mechanism 50 does not need to consume electric energy to unlock, so that the self-loss of the power generation system is reduced, and the power generation efficiency is improved.

Further, the locking mechanism 50 is located between the working umbrella 10 and the first drum 120, and the first cable 21 is connected in series with the locking mechanism 50 and then wound on the first drum 120. In the scheme, wind power drives the acting umbrella 10 to ascend, and the first cable 21 transmits tension to pull the main cable 20 to ascend to generate power. For a large sized umbrella 10, in order to reliably lock the first cable 21 and transmit a large pulling force, the locking mechanism 50 needs to be separately provided between the umbrella 10 and the first drum 120. After the first cable 21 is connected to the edge of the canopy of the work umbrella 10, it is first passed through the locking mechanism 50 and then wound up on the first drum 120.

Preferably, the umbrella cover edge of the working umbrella 10 is tied to the first cable 21; one of which is connected to the main rope 20 through a roller 30, and the working umbrella 10 is lifted and lowered along the main rope 20. In the scheme, the edge of the umbrella cover is fixedly connected with a first cable 21, one part of the first cable is movably connected with a main cable 20, so that the movement of the acting umbrella 10 along the main cable 20 can be limited, and a good air posture can be kept; on the other hand, when the working umbrella 10 is opened or closed, the working umbrella can rotate around the main cable rope 20 under the action of wind force, and the opening and the closing are easier, more efficient and more reliable. By using the roller 30 for movable connection, the abrasion between the edge of the umbrella surface of the acting umbrella 10 and the main cable 20 can be reduced.

In some embodiments, the locking mechanism is located on the rotational axis of the first spool. In the locked state, the first winding drum can only rotate unidirectionally, and the first winding drum can only wind the first cable. When in an unlocking state, the first winding drum can rotate bidirectionally, and the first winding drum can wind and unwind a first cable. In particular, the locking mechanism may be a ratchet mechanism.

In some embodiments, one end of the first cable is connected to a canopy edge of the work umbrella by a plurality of strings. The center of the top of the umbrella cover of the acting umbrella is connected to the main cable through a roller or a sleeve, and the acting umbrella ascends and descends along the main cable.

In this embodiment, the first reel 120 and the second reel 130 may idle on the winding shaft 140, respectively.

In this embodiment, the lock cylinder assembly 230 can swing freely around its root, and the top of the lock cylinder assembly 230 extends into the rope ladder passage 220. Latch bolt assembly 240 may provide one-way restriction of the swing of cylinder assembly 230. The rope ladder enters the rope ladder channel 220, two steps on the rope ladder are clamped by the top of the lock cylinder assembly 230, the rope ladder is continuously dragged from one direction, the rope ladder steps sequentially toggle the lock cylinder assembly 230 to swing, and the rope ladder passes through the rope ladder channel 220. In the locked state, the latch bolt assembly 240 restricts the lock cylinder assembly 230 from swinging only in one direction, so that the rope ladder can only be pulled through the rope ladder channel 220 in one direction; in the unlocked state, the lock cylinder assembly 230 resumes the bi-directional swing, and the rope ladder can be bi-directionally towed through the rope ladder passage 220. The lock column assembly 230 and the rope ladder step are matched in shape, and the lock tongue assembly 240 is used for limiting the swing of the lock column assembly 230 in one direction, so that the rope ladder can be locked in one direction, and a stable and reliable locking effect is achieved.

Specifically, the lock cylinder assembly 230 includes a lock cylinder 231 and a lock support 232; a locking support 232 is installed at one side of the rope ladder passage 220; the root of the locking column 231 is hinged on the locking support 232, the top of the locking column 231 stretches into between the steps of the rope ladder, and the locking column 231 can swing freely on the locking support 232.

Specifically, the latch bolt assembly 240 includes a locking tongue 241 and a guide groove 242; the guide groove 242 is positioned at one side of the rope ladder passage 220, and the locking tongue 241 is installed in the guide groove 242 and can move telescopically; the locking tongue 241 can unidirectionally block the locking post 231 from swinging when extending out of the guide groove 242, and is far away from the locking post 231 when retracting into the guide groove 242. The locking tongue 241 corresponds to a stopper located within the range of the swing of the locking post 231, and blocks the locking post 231 from swinging in a certain direction, thereby achieving the above-described one-way restriction. The locking tongue 241 may be located at the root, top, or hinge axis of the locking post 231. The guide groove 242 serves to support and guide the locking tongue 241 for telescopic movement.

In some embodiments, the latch bolt assembly may also be an electronically controlled one-way clutch mounted at the root of the lock cylinder assembly, and the drive assembly may be a corresponding control circuit.

The lock cylinder assembly 230 and the lock tongue assembly 240 are distributed along two sides of the rope ladder passage 220, which is beneficial to balancing the weight of the two sides of the rope ladder passage and avoiding the weight deviation of one side of the device. The vertical arrangement of the axes of the locking post 231 and the guide groove 242 is advantageous in maximizing the locking force of the rope ladder.

In some embodiments, the cylinder assembly and the bolt assembly may also be arranged on the same side, so long as the locking tongue is capable of achieving a one-way blocking of the locking cylinder. Furthermore, the locking tongue should be prevented from interfering with the rope ladder passing inside the rope ladder passage when retracting the guide groove (unlocked state).

Specifically, the driving assembly 250 includes a power member 251 and a link member 252; the link member 252 is provided with a first inclined surface, and the first inclined surface is abutted against the bottom of the locking tongue 241; the power member 251 pushes the link member 252 to move, and the first inclined surface pushes the locking tongue 241 to extend or retract the guide groove 242. The scheme utilizes inclined plane transmission to amplify the thrust output by the power piece 251 and convert the thrust direction into the expansion direction of the locking tongue 241, thereby reducing the specification of the power piece 251 and reducing the layout limitation of the driving assembly 250 on the locking body 210.

Further, a roller 243 is provided at the bottom of the locking tongue 241. The first inclined surface pushes the locking tongue 241 to extend or retract into the guide groove 242 by the roller 243.

Further, the opening side of the C-shaped rail 221 is provided with an inner curled edge 223, and the inner curled edge 223 has a partial blocking effect on two sides of the rope ladder, so as to prevent the rope ladder from being laterally deviated when passing through and separating from the rope ladder channel 220.

Optionally, a guide block 224 is arranged at the opening side of the C-shaped rail 221, and the guide block 224 extends into the space between the steps of the rope ladder; the guide block 224 can be toggled by its steps as the rope ladder passes over the C-track 221. The guide block 224 is deeper than the depth of the inner curled edge 223, and can play a better role in blocking, so as to prevent the rope ladder from being laterally deviated or separated from the rope ladder channel 220; meanwhile, the design that the guide block 224 can swing allows the rope ladder steps to be poked, so that the rope ladder can freely pass through the C-shaped track 221.

Optionally, the guide block 224 is provided with a counting sensor, and the counting sensor is used for obtaining the swinging times of the guide block 224 when the rope ladder passes through. When the rope ladder passes, each rope ladder step toggles the guide block 224 to swing once, and meanwhile, the interval of the rope ladder steps is a fixed length, so that the length of the rope ladder passing through the rope ladder channel=the interval of the steps×the swinging times.

In this embodiment, the locking post 231 of the locking post assembly 230 is cylindrical, and the top edge thereof is provided with rounded corners, so that the rope ladder steps can be smoothly moved.

After receiving the unlocking signal, the power piece 251 pushes the connecting rod to move, and two first inclined planes at one end of the connecting rod simultaneously push the locking tongue 241 to retract into the guide groove 242 through the roller 243. After the locking tongue 241 leaves the rope ladder passage 220 and is away from the locking post 231, the locking post 231 can swing bidirectionally, and the rope ladder can pass through the rope ladder passage 220 bidirectionally.
