Description

Technical Field

[0001] The technical field of this application is material transportation systems and new energy engineering construction, specifically involving a cableway-type autonomous transportation system and method for materials in a complex mountain photovoltaic power station. Background Technology

[0002] With the large-scale promotion and application of photovoltaic power generation in mountainous areas, the demand for the construction of photovoltaic power stations in complex mountainous environments is increasing. These areas typically feature steep terrain, inconvenient transportation, and variable climates, making traditional transportation methods unsuitable for construction requirements. Current technologies often employ specialized mountain vehicles for material transportation. This method relies on constructing temporary construction roads and using mechanical vehicles to transfer materials along winding mountain paths. Support structures are mostly ground tracks or simple supports, and power sources depend on external power supply or fuel-powered equipment. Transportation routes are limited by road layout, covering only a portion of the work area, and have limited adaptability to slope gradients. Furthermore, brittle materials such as photovoltaic panels are easily damaged during transportation due to bumps and jolting.

[0003] The aforementioned transportation methods have significant drawbacks: First, road construction requires large-scale excavation of mountains, damaging vegetation and soil structure, which does not meet ecological and environmental protection requirements; second, vehicle passage is difficult in complex terrain, resulting in low transportation efficiency and high safety risks; third, conventional transportation cannot achieve full-area coverage, still requiring a large amount of manual secondary handling, significantly increasing labor costs and construction time; in addition, the unstable power supply in remote mountainous areas restricts the operation of automated transportation systems. Therefore, there is an urgent need for a highly efficient material transportation solution that is not limited by terrain, is environmentally friendly, can operate fully automatically, and can cover the entire photovoltaic array area. Summary of the Invention

[0004] The purpose of this invention is to provide a cableway-based autonomous transportation system and method for materials in complex mountainous photovoltaic power stations, which can solve the technical problems of difficult transportation of photovoltaic materials, serious ecological damage, high dependence on manual labor, and insufficient energy supply in complex mountainous environments.

[0005] To achieve the above objectives, the present invention provides the following technical solutions: In a first aspect, the present invention provides a cableway-type autonomous transportation system for materials in a complex mountain photovoltaic power station, comprising a support structure, a self-powered system, and a cableway system. The supporting structure includes columns and crossbars, with the crossbars fixed to the columns; the self-powered system is used to provide independent power to the cableway system in the absence of external power supply in the field; the cableway system includes a first load-bearing cable, a second load-bearing cable, a first traction cable, a second traction cable, a drive control device, and a transport device; The drive control device is connected to the output end of the self-powered system via a wire, and the drive control device is connected to the transport device via a signal line; the two ends of the first load-bearing cable are fixed to the mountainside and the foot of the mountain by anchoring devices; the second load-bearing cable is a horizontal load-bearing cable, and the two ends of the second load-bearing cable are fixed to the first load-bearing cable; the second load-bearing cable is used to bear the entire weight of the transport device and the photovoltaic panels being transported and to provide a moving track for the transport device. One end of the first traction cable is connected to the drive control device, and the other end is fixed to the rear traction ring of the transport device. One end of the second traction cable is fixed to the side traction ring of the transport device.

[0006] Furthermore, the supporting structure also includes a foundation, on which the columns are fixed; the structural shape of the columns can be either Y-shaped columns or lattice columns, and the overall form of the supporting structure at the foot of the mountain and the mountainside is a portal structure.

[0007] Furthermore, the self-powered system includes a photovoltaic panel, a controller, a battery, an inverter, and a frequency converter; the photovoltaic panel is electrically connected to the input terminal of the controller, the output terminal of the controller is electrically connected to the battery, and the battery is electrically connected to the drive control device in sequence through the inverter and the frequency converter.

[0008] Furthermore, the cableway system also includes a first pulley and a second pulley. The first pulley is mounted on the first support cable, and the second pulley is mounted on the second support cable. The second pulley is rotatably connected to the hook at the top of the transport device, and the second support cable can move longitudinally with the pulley on the first support cable.

[0009] Furthermore, the transport device is a replaceable structure, including a rectangular loading frame and a bulk material cylinder; the rectangular loading frame is composed of rigid rods, and the upper part of the rectangular loading frame is provided with rigid or flexible inclined supports connected to the hook.

[0010] Furthermore, the cableway system is either reciprocating or circulating; the second traction cable is driven by human power or electricity.

[0011] Furthermore, the power source of the drive control device is any one of a self-powered system, a fuel generator, or manual drive; when manual drive is used, the pulley is equipped with a locking device to fix the position of the pulley, and the transport device can use its own weight to return to the foot of the mountain.

[0012] Furthermore, the rectangular loading frame can be a load-bearing structure of the type of tieable plate or a slender shape; the bulk material cylinder can be a hanging basket or a hanging frame load-bearing structure.

[0013] Secondly, the present invention also provides a method for autonomous cableway transportation of materials for complex mountain photovoltaic power stations, which employs an autonomous transportation system and includes the following steps: The two ends of the first load-bearing cable are fixed to the mountainside and the foot of the mountain by anchoring devices, and the two ends of the second load-bearing cable are fixed to the first load-bearing cable, so that the second load-bearing cable forms a horizontal load-bearing track. Connect the drive control device to the output terminal of the self-powered system via a wire, and at the same time establish a signal connection between the drive control device and the carrier device via a signal line. Connect one end of the first traction cable to the drive control device and fix the other end to the rear traction ring of the carrier device; fix one end of the second carrier cable to the side traction ring of the carrier device. The self-powered system supplies independent power to the drive control device in the field where there is no external power supply, thus completing the power preparation before transportation. The photovoltaic panels required for the photovoltaic power station are placed inside the transport device. The drive control device sends a control signal to drive the first traction cable to move the transport device along the second bearing cable. The second bearing cable bears the entire weight of the transport device and the transported photovoltaic panels, realizing the directional transport of photovoltaic panels between the foot of the mountain and the mountainside. After the photovoltaic panels arrive at the target location, they are unloaded. The first traction cable is controlled by the drive control device, which drives the transport device back to the initial position along the second load-bearing cable, completing a single photovoltaic panel transport process.

[0014] Furthermore, the cableway system also includes a first pulley and a second pulley. When assembling the cableway system, the first pulley is fitted onto the first load-bearing cable, and the second pulley is fitted onto the second load-bearing cable and rotatably connected to the hook at the top of the transport device. During transportation, when it is necessary to adjust the longitudinal position of the second load-bearing cable, the first pulley is moved along the first load-bearing cable, which simultaneously drives the second load-bearing cable and the transport device to complete the longitudinal position adjustment, adapting to the needs of different mountain transport points.

[0015] Compared with the prior art, the present invention has the following beneficial technical effects: This invention provides a cableway-type autonomous transportation system for materials in complex mountainous photovoltaic power stations. The system comprises a double-layer cableway structure consisting of a first and a second supporting cable. The second supporting cable moves longitudinally with the first supporting cable and serves as the horizontal transport track for the transport device, thus achieving full-area coverage transportation in complex mountainous terrain. This solves the problem of traditional transportation being limited by terrain and unable to directly reach construction sites. A self-powered system supplies energy to the drive and control device, eliminating dependence on the external power grid and adapting to remote, power-free environments. The first traction cable actively pulls the transport device along the second supporting cable, achieving automated and continuous transportation, significantly improving transportation efficiency and reducing manual labor intensity and construction costs. The entire system has a simple structure, is easy to install, and is reusable, exhibiting good environmental and economic benefits. Attached Figure Description

[0030] To address the transportation challenges faced in constructing photovoltaic power stations in complex mountainous environments, existing technologies generally rely on building temporary roads or using specialized vehicles and drones for material transport. However, in mountainous areas with steep slopes, significant elevation differences, dense vegetation, and variable climates, conventional transportation methods have obvious limitations: on the one hand, road construction is not only costly but also causes irreversible damage to the surface ecosystem; on the other hand, specialized mountain vehicles are limited by their climbing ability and accessibility, making it difficult to cover all construction sites, while drones are greatly affected by load capacity, range, and weather conditions, failing to meet the needs of large-scale, continuous transportation. Furthermore, materials such as photovoltaic panels, brackets, and micropile foundations are large, fragile, and diverse, making traditional manual handling inefficient and posing high safety risks, severely hindering construction progress. Therefore, this invention provides the following technical solution: See Figures 1 to 2 This invention provides a fully automated cableway-type transportation system for materials in complex mountain photovoltaic power stations, including a support structure, a self-powered system, and a cableway system. The support structure includes a column 32 and a crossbar 31, with the crossbar 31 fixed to the column 32; the self-powered system is used to provide independent power to the cableway system in the field where there is no external power supply; the cableway system includes a first load-bearing cable 1, a second load-bearing cable 2, a first traction cable 11, a second traction cable 21, a drive control device 14, and a transport device 6; The drive control device 14 is connected to the output terminal of the self-powered system via a wire, and the drive control device 14 is connected to the transport device 6 via a signal line; the two ends of the first bearing cable 1 are fixed to the mountainside and the foot of the mountain by anchoring devices; the second bearing cable 2 is a horizontal bearing cable, and the two ends of the second bearing cable 2 are fixed to the first bearing cable 1; the second bearing cable 2 is used to bear the entire weight of the transport device 6 and the transported materials and to provide a moving track for the transport device 6. One end of the first traction cable 11 is connected to the drive control device 14, and the other end is fixed to the rear traction ring of the carrier device 6. One end of the second traction cable 21 is fixed to the side traction ring of the carrier device 6.

[0031] The supporting structure includes columns 32 and crossbars 31, which are fixedly connected by welding, bolts, or other reliable methods to ensure the overall stability of the structure. Columns 32 are vertically installed and anchored to the mountain foundation to bear the vertical loads and lateral tensions from the overhead cableway system. Crossbars 31 are horizontally installed at the top or middle of the columns, providing a turning fulcrum or tension support for the first load-bearing cable 1. The supporting structure can adopt different foundation types, such as concrete independent foundations, pile foundations, or rock anchor foundations, depending on the actual terrain and load requirements, to adapt to soft soil, rock, or stony terrain.

[0032] In a more specific embodiment of the present invention, column 32 can be a steel Y-shaped column or a lattice column, which has high bending and torsional resistance, while reducing its own weight and facilitating transportation and installation in mountainous areas.

[0033] The first load-bearing cable 1 is laid longitudinally along the mountainside, with both ends fixed to stable geological points on the mountainside and at the foot of the mountain respectively by high-strength anchoring devices, forming the main load-bearing path across the elevation difference. The first load-bearing cable 1 is usually made of high-strength steel wire rope, which has good tensile strength and corrosion resistance and can withstand dynamic loads for a long time.

[0034] The second load-bearing cable 2 is a horizontally arranged auxiliary transport track. In this embodiment, an integrated transportation platform consisting of a support structure, a self-powered system, and a cableway system is constructed to achieve safe and efficient transportation of various photovoltaic materials in complex mountainous environments with no external power supply and inconvenient transportation. The system utilizes an aerial cableway to overcome terrain obstacles, avoiding ground excavation, and combines replaceable transport devices with distributed power control to form a flexible and controllable aerial assembly line. The two ends are not directly fixed to the ground but are connected to sliding nodes such as pulleys and hooks on the first support cable 1, allowing it to move longitudinally with the first support cable 1, thereby expanding the lateral service range. The second support cable 2 directly bears the entire weight of the transport device 6 and the photovoltaic panels 7 it carries, and serves as a guide track for the transport device 6 to move horizontally, resulting in a clear structural stress distribution and stable operation.

[0035] The transport device 6 is used to load different types of materials. The transport device 6 is equipped with a rear traction ring and a side traction ring, which are used to connect the first traction cable 11 and the second traction cable 21, respectively. The first traction cable 11 is driven by the drive control device 14, which pulls the transport device 6 forward or backward along the second carrying cable 2 to complete the main transport task. The second traction cable 21 is connected to the side traction ring and can be used for lateral fine-tuning of position or manual operation to improve delivery accuracy and operational flexibility.

[0036] Through the above technical solution, this application achieves directional transportation of photovoltaic materials without the need for construction roads in complex mountainous conditions. Due to the adoption of a double-layer cableway structure—the first load-bearing cable 1 providing longitudinal crossing and the second load-bearing cable 2 serving as the horizontal transport track—the system can establish a stable aerial transport channel in steep slopes, ravines, and other terrains, effectively overcoming the dependence of traditional transportation methods on terrain accessibility. Independent power supply through a self-powered system solves the problem of power shortages in remote areas, enhancing the system's deployment flexibility and sustainable operation capabilities. The second load-bearing cable 2 directly bears the entire load and serves as the moving track, making the transport device 6 operate more smoothly and reducing the impact of vibration on vulnerable materials such as photovoltaic panels 7. The first traction cable 11 is actively pulled by the drive control device 14, achieving automated round-trip transportation and improving transportation efficiency and controllability; while the second traction cable 21, connected to the side traction ring, provides an interface for local position adjustments, enhancing the system's adaptability to complex working conditions.

[0037] In a more specific embodiment of the present invention, by adding a foundation to the existing support structure and optimizing the column 32 and the overall structural form, the structural stability and load-bearing capacity of the system in complex mountainous environments are improved. The foundation, as the connecting component between the support structure and the ground, plays a crucial role in effectively transferring the superstructure load to the soil and rock mass. It can be in the form of reinforced concrete cast-in-place or precast pile foundations, with the embedment depth determined according to the geological survey results to ensure sufficient resistance to uplift, slippage, and settlement control, especially suitable for soft foundations with thick weathered layers and low bearing capacity. The column 32 is vertically installed on the foundation and serves as the main vertical load-bearing component, supporting the horizontal bar 31 and the concentrated load of the load-bearing cable system. To enhance its lateral stiffness and anti-overturning performance, the structural shape of the column 32 can be a Y-shaped column or a lattice column. Y-shaped columns, supported by three legs, create a wide-angle bracing, increasing the base load-bearing area and improving overall stability. They are particularly suitable for areas with high wind pressure or active seismic activity. Lattice columns, on the other hand, are constructed from multiple angle steels or steel pipes connected by bracing strips or plates. They are lightweight, rigid, and have strong torsional resistance, making them suitable for mountainous terrain with large slenderness ratios and difficult transportation. Both structural forms can be flexibly selected based on the actual terrain slope, load size, and construction conditions, effectively improving the structural safety of the columns under dynamic traction loads.

[0038] The horizontal bar 31 is fixed horizontally to the top or middle of the column 32, forming a lateral connecting component of the portal structure, and together with the column 32, forming a closed frame system. The support structure at the foot and middle of the mountain is designed as a portal structure, that is, a rigidly connected portal frame consisting of two columns 32 and one or more horizontal bars 31. This structure has good spatial integrity and load distribution capacity, and can effectively resist asymmetrical tension from the cableway system, wind vibration impact, and inertial forces generated when the transport device starts and stops. The portal structure also facilitates the anchoring and steering arrangement of the load-bearing cable 1, and provides a stable suspension point for the pulley assembly. In addition, this structural form is easy to install, and can be quickly assembled by bolting or welding, adapting to construction environments in the field without large hoisting equipment.

[0039] In a more specific embodiment of the present invention, the self-powered system includes a photovoltaic panel, a controller, a battery, an inverter, and a frequency converter; the photovoltaic panel is electrically connected to the input terminal of the controller, the output terminal of the controller is electrically connected to the battery, and the battery is electrically connected to the drive control device 14 in sequence through the inverter and the frequency converter.

[0040] In a more specific embodiment of the present invention, the cableway system further includes a first pulley 12 and a second pulley 22. The first pulley 12 is mounted on the first support cable 1, and the second pulley 22 is mounted on the second support cable 2. The second pulley 22 is rotatably connected to the hook at the top of the transport device 6, and the second support cable 2 can move longitudinally with the pulley 12 on the first support cable 1.

[0041] This technical solution, through the structural design of a first pulley 12 and a second pulley 22, achieves dynamic adjustment of the spatial position of the second load-bearing cable 2. Specifically, the first pulley 12 slides along the first load-bearing cable 1, causing the second load-bearing cable 2, which is fixedly connected to it, to achieve longitudinal displacement. The second pulley 22 serves as a transitional connection between the second load-bearing cable 2 and the transport device 6, allowing the transport device to swing freely in the horizontal direction and adapt to local posture changes, thereby improving the stability and safety of the transportation process.

[0042] The first pulley 12 is an annular roller structure that can roll or move freely along the axial direction of the first supporting cable 1. Its inner ring has a groove that matches the first supporting cable 1 to ensure that the cable does not detach during operation. This pulley is made of high-strength alloy steel or engineering plastic, and its outer surface can be covered with a wear-resistant rubber layer to reduce cable wear. Multiple first pulleys 12 can be installed according to the actual span and load distribution, evenly distributed on the first supporting cable 1 to form a multi-point support structure. When it is necessary to adjust the height of the second supporting cable 2, the first pulley 12 can be moved up and down along the first supporting cable 1 by manual pulling, winch traction, or an electric drive device, thereby changing the vertical position of its suspension point. Since both ends of the second supporting cable 2 are directly fixed to the first pulley 12, its entire structure rises and falls synchronously, achieving flexible adjustment of its longitudinal position.

[0043] In this embodiment, since the first pulley 12 can move longitudinally on the first supporting cable 1, it drives the second supporting cable 2 to change its overall suspension height. Therefore, it can adapt to the installation positions of photovoltaic panels 7 at different altitude levels, solving the problem that traditional fixed cableways cannot cover multiple construction surfaces. At the same time, the rotational connection between the second pulley 22 and the hook effectively releases torsional constraints, avoiding additional stress caused by posture limitations of the transport device during operation, and improving suspension stability and smooth operation. The overall structure is simple and reliable, and it can realize the material transport function of full-area, multi-level, and precise delivery without the need for additional complex supports or power modules, significantly enhancing the applicability and flexibility of the system in complex mountainous environments.

[0044] See Figures 1 to 4 In a more specific embodiment of the present invention, the transport device 6 is a replaceable structure, including a rectangular loading frame 61 and a bulk material cylinder 62. The rectangular loading frame 61 is composed of rigid rods, and a rigid or flexible inclined support connected to a hook is provided on the upper part of the rectangular loading frame 61. The rectangular loading frame 61 is composed of rigid rods, forming a stable rectangular spatial skeleton structure. A rigid or flexible inclined support connected to a hook is provided on the upper part of the rectangular loading frame 61. One end of the inclined support is connected to the top corner point or side reinforcement node of the frame, and the other end extends upward and forms a rotating or hinged connection with the hook at the top of the transport device. When a rigid inclined support is used, it is usually a steel pipe or steel section component, connected to the hook through ear plates and pins, which can effectively transmit tensile and compressive loads and reduce lateral sway. When a flexible inclined support is used, high-strength synthetic fiber ropes or steel wire ropes can be selected, which have a certain elastic deformation capacity, can absorb some vibration energy, and improve the stability of transportation. This dual-mode support design allows for selection based on the material's center of gravity distribution and the degree of bumpiness along the transport route: rigid supports are preferred for long-distance main cableway transport with significant elevation differences to enhance stability; while flexible supports can be used for short-distance fine-tuning or sections with severe terrain undulations to mitigate impact.

[0045] The bulk material hopper 62, as another type of replaceable carrying unit, can be used to transport loose or small-volume materials such as cement, sand, bolt bundles, and cable junction boxes. The bulk material hopper 62 can be replaced with a basket or frame structure to accommodate the transportation needs of irregularly shaped small equipment or tool kits. All replaceable parts are equipped with standardized interfaces, allowing for reliable assembly and disassembly with the main body of the transport device via quick-connect pins, clips, or threaded connections.

[0046] In a more specific embodiment of the present invention, the cableway system is either reciprocating or circulating; the second traction cable 21 is driven by human power or electricity.

[0047] In a more specific embodiment of the present invention, the power source of the drive control device 14 is any one of a self-powered system, a fuel generator, or manual drive; when manual drive is used, a locking device is provided on the pulley 12 to fix the position of the pulley 12, and the carrying device 6 can use its own weight to return downward to the foot of the mountain. In this embodiment, a locking device is provided on the pulley 12. This device can be a mechanical ratchet locking structure, a pin positioning mechanism, or an electromagnetic braking assembly. Its function is to lock the longitudinal position of the pulley 12 on the first carrying cable 1 during loading and unloading of materials or during pause in operation, to prevent the carrying device from moving accidentally due to cable slippage, thereby avoiding the risk of falling objects or collisions from heights.

[0048] In a more specific embodiment of the present invention, the rectangular loading frame 61 can be a load-bearing structure of the form of a tieable plate or an elongated shape; the bulk material cylinder 62 can be a hanging basket or a hanging frame load-bearing structure. This application achieves efficient adaptability and transportation of materials of different shapes.

[0049] In another embodiment of the present invention, the present invention also provides a method for autonomous cableway transportation of materials for complex mountain photovoltaic power stations, employing the aforementioned autonomous transportation system: Includes the following steps: The two ends of the first load-bearing cable 1 are fixed to the mountainside and the foot of the mountain by anchoring devices, and the two ends of the second load-bearing cable 2 are fixed to the first load-bearing cable 1, so that the second load-bearing cable 2 forms a horizontal load-bearing track. The drive control device 14 is connected to the output terminal of the self-powered system via a wire, and at the same time, a signal connection is established between the drive control device 14 and the carrier device 6 via a signal line. One end of the first traction cable 11 is connected to the drive control device 14, and the other end is fixed to the rear traction ring of the carrier device 6. One end of the second carrier cable 2 is fixed to the side traction ring of the carrier device 6. The self-powered system supplies independent power to the drive control device 14 in the field where there is no external power supply, thus completing the power preparation before transportation. The photovoltaic panels 7 required for the photovoltaic power station are placed in the transport device 6. The drive control device 14 sends a control signal to drive the first traction cable 11 to move the transport device 6 along the second bearing cable 2. The second bearing cable 2 bears the weight of the transport device 6 and the transported photovoltaic panels 7, realizing the directional transport of the photovoltaic panels 7 between the foot of the mountain and the mountainside. After the photovoltaic panel 7 arrives at the target location, it is unloaded. The first traction cable 11 is controlled by the drive control device 14, which drives the carrying device 6 to return to the initial position along the second carrying cable 2, thus completing a single photovoltaic panel 7 transportation process.

[0050] In a more specific embodiment of the present invention, the cableway system further includes a first pulley 12 and a second pulley 22. When assembling the cableway system, the first pulley 12 is fitted onto the first support cable 1, and the second pulley 22 is fitted onto the second support cable 2 and rotatably connected to the hook at the top of the transport device 6. During transportation, when it is necessary to adjust the longitudinal position of the second support cable 2, the first pulley 12 is driven to move along the first support cable 1, and the second support cable 2 and the transport device 6 are simultaneously driven to complete the longitudinal position adjustment to adapt to the needs of different mountain transport points.
