Description

Technical Field

[0001] This disclosure relates to the field of high-altitude wind power generation, specifically to a system and method for lifting and recovering high-altitude wind power generation equipment. Background Technology

[0002] To maximize resource utilization, umbrella ladder-type high-altitude wind power generation systems are typically designed with multiple launch piles paired with generator units within the same powerhouse. This means that in practical applications, aerial modules need to be launched simultaneously from multiple launch piles. Currently, most umbrella ladder-type high-altitude wind power systems use manual traction to transfer the aerial modules between the inflatable platform and the launch piles.

[0003] Manual traction is time-consuming, labor-intensive, inefficient, and poses certain safety hazards. To balance power generation and safe distance, levitation piles are typically distributed widely. Traditional levitation and retrieval methods often require the construction of manual access routes, wasting land resources and increasing labor costs. Furthermore, current levitation and retrieval systems and methods are limited by geographical conditions and are unsuitable for areas with complex terrain, such as islands. Summary of the Invention

The first winch is, for example, a large winch with a 20-ton specification.

[0053] The working unit is connected to the working rope 101, which is connected to the ground power generation unit 100 (ground power plant) via a second winch. The working unit is lifted into the air at the lifting pile 102, where a small third winch 103 and a second traction rope 104 connected to it are located. In a preferred embodiment, to drive the generator in the power plant to achieve continuous periodic power generation, the ground power generation unit 100 is connected to at least two of the working units. The shared platform 105 is provided with a platform 110 corresponding to each working unit, which is used for the lifting and retrieval of the working unit. The shared platform 105 is typically built close to the power plant to facilitate the transportation and disposal of equipment and modules.

[0054] In the preferred embodiment, the upper part of the lifting pile 102 is equipped with a universal rotating mechanism, which can rotate 360 ​​degrees according to the wind direction, and can also automatically adapt the pitch angle according to the lifting angle of the lifting module. After the power cable comes out from the ground power generation unit, it is guided into the interior of the lifting pile, and then passes through the universal rotating mechanism at the top of the lifting pile to connect to the airborne power unit.

[0055] Wherein, when the second traction rope 104 and the first traction rope 108 are connected, the third winch 103 pulls the first traction rope 108 by pulling the second traction rope 104; when the first traction rope 108 is connected to the working unit, the first winch 107 pulls the working unit by pulling the first traction rope 108; the anchoring device 106 is used to anchor the working unit, the working unit including a working module composed of a plurality of working umbrellas 300 connected in sequence.

Its cavity contains a wound auxiliary rope 401, and also houses a wireless transceiver unit for communication, a bottom cavity door switch unit, and a power supply module. One end of the auxiliary rope 401 passes through the bottom opening and is then wound into the equipment cable 301. When the switch unit receives an opening command from the ground, the cavity door at the bottom of the assist device 400 will fully open, and the internal wound cable will suspend to the ground under gravity to assist in the retrieval of the work unit equipment.

[0060] In a preferred embodiment, the working unit is further provided with a GPS positioning module for monitoring orientation, a sensor module for monitoring altitude, a wireless transceiver module for receiving and processing ground control information, and a power generation module for supplying power to the positioning device, the sensor, and the wireless transceiver.

[0064] 3) After completing the above actions, release the triangular pulley plate 200 at the bottom of the module containing the helium balloon 600, which is anchored to the anchoring device 106, so that it is pulled by the helium balloon 600 and guides the lower balancing parachute into the air. During the ascent, control the rope release speed of the first winch 107 so that the module containing the helium balloon 600 and the module containing the balancing parachute 500 are raised in sequence and under control.

[0065] 4) When the module in step 3) cannot be lifted further because the bottom triangular pulley plate 200 of the module where the balance umbrella 500 is located is anchored, the end of the first traction rope 108 of the first winch 107 that is fixed on the anchoring device 106 is released, and the first winch 107 is controlled to retract the first traction rope 108.

[0066] 5) Repeat the above steps to sequentially and controllably launch each module, including several power umbrellas 300, into the air.

[0067] 6) As attached Figure 5 As shown, the end of the working rope 101 of the ground power generation unit 100, which is stuck on the platform 110, is attached to one of the pulleys of the bottom triangular pulley plate 200 of the working unit, which is anchored on the anchoring device 106. At the same time, the end of the first traction rope 108 of the first winch 107 and the end of the second traction rope 104 of the third winch 103, which is stuck on the platform 110 and corresponds to the lifting pile, are attached together to the other pulley of the bottom triangular pulley plate 200.

[0068] 7) After the above preparation work, unlock the anchoring device of the bottommost triangular pulley plate 200 that is anchored, and at the same time control the first winch 107 and the second winch corresponding to the ground power generation unit to guide the above work unit to be gradually transferred to the lifting pile 102 under control.

[0069] 8) Disassemble the first traction rope 108 of the first winch 107 and the second traction rope 104 of the third winch 103 together from the bottom triangular pulley plate 200, and control the first winch 107 to pull the first traction rope 108 and the second traction rope 104 back to the common platform 105 for later use.

[0070] 9) The unit performs work by rising into the air to generate electricity under the control of the power plant.

[0071] Using the same method, the aerial systems corresponding to the other launching piles were launched sequentially, as shown in the attached diagram. Figure 1 As shown.

[0072] The recovery of the work unit in the high-altitude wind power generation equipment lift-off and recovery system of this embodiment includes the following steps:

[0073] 1) As attached Figure 6As shown, first close the working umbrella of the aerial working unit, and then pull the aerial working unit back through the second winch of the ground power generation unit until the triangular pulley plate 200 of the lowest working umbrella reaches the lifting pile 102.

[0074] 2) Control the second traction rope 104 of the third winch 103 at the elevated pile 102 to drag the first traction rope 108 of the first winch 107 of the shared platform 105 to the elevated pile 102; as attached Figure 7 As shown, the first traction rope 108 of the first winch 107 and the second traction rope 104 of the third winch 103 are assembled together onto the triangular pulley plate 200 of the above steps.

[0075] 3) The second winch of the ground power generation unit 100 and the first winch 107 of the shared platform 105 jointly pull the aerial work module to the platform 110 corresponding to the recovery platform. Then, the bottom triangular pulley plate 200 is anchored on the anchoring device 106. Then, the first traction rope 108 of the first winch 107 mounted on the triangular pulley plate 200 is released for later use.

[0076] 4) As attached Figure 8 As shown, the assist device 400 of the power umbrella adjacent to the lowest power umbrella of the aerial power module releases the auxiliary rope 401 to the ground, and then connects the end of the first traction rope 108 of the first winch 107 to the auxiliary rope 401 released by the assist device 400.

[0077] 5) Control the first winch 107 to continue dragging the aerial work module down until the triangular pulley plate 200 at the bottom of the assist device 400 reaches the common platform, and then anchor the triangular pulley plate 200 on the anchoring device 106. At this point, the bottom module of the aerial work unit has completely landed on the common platform, and can be stored or replaced as needed;

[0078] 6) Repeat the above steps to recover and dispose of all modules of the entire aerial work unit in segments.
