Description

Technical Field

[0001] This invention belongs to the field of mountain photovoltaic power generation technology, and specifically relates to a multi-point construction material supply system and method for mountain photovoltaic power generation. Background Technology

[0002] Mountain photovoltaic power generation projects are characterized by complex terrain and scattered construction sites, making material supply significantly more difficult than in flat terrain. Currently, existing material supply technologies mainly fall into two categories: one is the "vehicle transportation + manual secondary handling" model, where materials are transported by truck to the vicinity of the construction site and then transferred to the work area manually or with simple machinery; the other is the use of simple tools for handling in areas with rugged terrain that are inaccessible by vehicles.

[0003] The aforementioned existing technologies have the following critical problems that urgently need to be addressed: Firstly, the material supply efficiency is low, and manual handling and animal transport have small carrying capacity and slow speed, which cannot meet the progress requirements of large-scale construction. Secondly, it has poor energy consumption and adaptability. Some transportation methods rely excessively on external power, and it is difficult to flexibly adjust the material supply structure according to the elevation differences of mountainous terrain, thus limiting its applicability.

[0004] Therefore, developing a technical solution that can adapt to complex mountainous terrain and achieve efficient and safe material supply from multiple points has become an urgent need in the field of mountain photovoltaic power generation construction. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a multi-point construction material supply system and method for mountain photovoltaic power generation. The present invention sets up a centralized material supply point and multiple starting support frames on the working platform, so that each starting support frame corresponds to a decentralized construction point, forming a multi-path parallel material supply structure. This structure can flexibly schedule the material supply sequence according to the urgency of the needs of each construction point, without relying on the roads between construction points to transfer materials, effectively avoiding the limitation of the conveying capacity when supplying materials along a single path, and avoiding the problem of material transfer obstruction caused by poor road conditions.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: A multi-point construction material supply system for mountain photovoltaic power generation includes a centralized material supply point for supplying materials to multiple dispersed construction points; the height of the centralized material supply point is higher than the height of the dispersed construction points. A sliding cable is installed between the centralized material supply point and the decentralized construction point. A sliding seat is slidably installed on the sliding cable, and the sliding seat is connected to the pulling rope and the pulling rope traction device through a pull rope. A lifting device is installed on the sliding seat, which is used to connect the material basket.

[0007] Preferably, a feeding tower is provided at the centralized feeding point, and the feeding tower is equipped with a tower crane and a working platform; The tower crane device is used to lift materials onto the working platform; The aforementioned work platform is used to store materials that need to be transported.

[0008] Preferably, the working platform is provided with multiple starting support frames, each starting support frame corresponds to a distributed construction point, each distributed construction point is provided with an ending support frame, and a sliding cable connects the starting support frame and the ending support frame.

[0009] Preferably, a rope traction device is installed on the starting support frame, the rope traction device including a winch installed on the starting support frame, the winch being connected to the sliding seat via a rope; When the centralized material supply point is transporting materials to the decentralized construction points, the winch is used to share part of the weight of the material basket, so that the material basket slides down slowly; When an empty spreader needs to return, a winch is used to pull the spreader up.

[0010] Preferably, the lifting device includes a hand-operated hoist, which is connected to a load-bearing beam. The load-bearing beam is equipped with a movable basket connector, which is used to connect the material basket.

[0011] Preferably, the load-bearing beam is a T-beam, and the movable suspended platform connector is slidably installed on the load-bearing beam. The position of the movable suspended platform connector is adjusted by a position adjustment mechanism.

[0012] Preferably, the position adjustment mechanism includes a lead screw, which is mounted on the load-bearing beam via a bearing seat. The two ends of the lead screw are respectively provided with a positive thread and a negative thread, which are threadedly engaged with two movable suspended platform connectors. The lead screw is driven to rotate by a worm gear reducer, and the rotation of the lead screw drives the movable suspended platform connectors to move.

[0013] Preferably, the worm gear reducer is equipped with a rotating head driven by an electric wrench.

[0014] Preferably, the movable suspended basket connector is connected to the material suspended basket via a lifting rope or hook.

[0015] Preferably, the material basket is equipped with a vibration sensor and a vibrator.

[0016] Preferably, the material basket is a hanging tank, a hanging frame, or a hanging box, and the size and dimensions of the material basket are determined by the material being lifted.

[0017] Preferably, the arrangement of centralized material supply points includes at least one of the following: Arrangement Method 1: When the centralized material supply point is higher than the decentralized construction point, and the height difference between the centralized material supply point and the decentralized construction point is sufficient for the material basket to slide down under its own weight, no tower for raising the height is installed at the centralized material supply point. Arrangement Method 2: When the height difference between the centralized material supply point and the decentralized construction point is insufficient to allow the material basket to slide down under its own weight, an extended tower is installed at the centralized material supply point.

[0018] An operation method for a multi-point construction material supply system for mountain photovoltaic power generation includes the following: Material preparation and suspended platform selection: Based on the material requirements of the dispersed construction sites, determine the type, specifications, and quantity of the materials to be transported; select a suitable material suspended platform. Centralized material supply point hoisting: Operate the tower crane on the centralized material supply tower to hoist the prepared materials from the ground to the working platform of the supply tower; during the hoisting process, ensure that the lifting weight of the tower crane does not exceed the rated load, and keep the materials stable during the hoisting process to avoid collision with the supply tower structure; Cableway and lifting device connection and debugging: According to the target dispersed construction points, start the designated starting support frame on the work platform accordingly; check whether the cableway between the starting support frame and the ending support frame of the target construction point is taut and undamaged, and whether the sliding seat slides smoothly on the cableway; Install the lifting device on the sliding seat, specifically by: securely connecting the hand chain hoist to the load-bearing beam, and then installing the mobile suspended platform connector on the T-shaped load-bearing beam; The position of the movable suspended basket connector is adjusted by the position adjustment mechanism: the rotating head of the worm gear reducer is driven by an electric wrench, which drives the lead screw to rotate; since the two ends of the lead screw are respectively provided with positive and negative threads, and are threadedly engaged with the two movable suspended basket connectors, the rotation of the lead screw can drive the two movable suspended basket connectors to move closer or further away synchronously until the connection distance is adjusted to match the material suspended basket. Material basket connection and load check: Connect the material basket to the movable basket connector of the lifting device using a lifting rope or hook, ensuring that the connection point is firm and reliable with no risk of loosening; after the connection is completed, operate the hand chain hoist to fine-tune the height of the material basket so that the material basket is in a horizontal state; at the same time, check whether the rope connection between the winch and the sliding seat of the rope traction device is tight and whether the braking system of the winch is normal. Material transport to dispersed construction points: The rope traction device on the starting support frame is activated, and the winch begins to work; Since the centralized material supply point is higher than the dispersed construction points, the material basket tends to slide down under the influence of gravity. At this time, the winch uses the rope to share part of the weight of the material basket, controlling the material basket to slide down the cableway slowly and steadily towards the dispersed construction points; During the transport process, the data from the vibration sensor on the material basket is monitored in real time. If the vibration frequency of the material basket tends to the natural frequency, it is finely adjusted by the vibrator to ensure that the material basket runs stably along the cableway until it reaches the end support frame at the dispersed construction points; Empty basket return retrieval: After the workers at the dispersed construction sites unload the materials, they check whether the material basket is intact; then, they start the winch of the rope traction device. The winch pulls the sliding seat, empty lifting equipment, and material basket up the cable via the rope and returns to the starting support frame of the centralized material supply point; the connection between the material basket and the lifting equipment is disconnected, completing one material supply cycle.

[0019] Preferably, the multi-construction-point alternating supply process is as follows: when materials need to be supplied to multiple dispersed construction points, the materials are transported separately through multiple starting support frames on the work platform. The supply sequence is reasonably arranged according to the urgency of the material needs of each construction point to achieve efficient and coordinated multi-point material supply.

[0020] Preferably, if the material basket is transporting commercial cement, the vibrator is continuously turned on during the transportation process.

[0021] Preferably, in the material preparation and basket selection, if the material is in bulk, a basket is selected; the bulk material includes sand, gravel, and bolts. If the material is a component, a hanger should be selected; the component includes photovoltaic brackets and photovoltaic panels. If the material is a precision instrument or a small tool, an enclosed lifting basket should be selected to ensure that the size and dimensions of the material lifting basket match the material being lifted.

[0022] A method for supplying construction materials at multiple points in mountain photovoltaic power generation includes the following steps: Based on the mountainous terrain, the density of photovoltaic construction sites, and the total amount of component materials, at least one centralized material supply point should be planned. The layout of the centralized material supply point should include at least one of the following: Arrangement Method 1: When the centralized material supply point is higher than the decentralized construction point, and the height difference between the centralized material supply point and the decentralized construction point is sufficient for the material basket to slide down under its own weight, no tower for raising the height is installed at the centralized material supply point. Arrangement Method 2: When the height difference between the centralized material supply point and the decentralized construction point is insufficient for the material basket to slide down under its own weight, an extended tower is installed at the centralized material supply point; Materials are transported to a centralized material supply point, from which they are then supplied to various dispersed construction sites. The material supply and transportation methods include at least one of the following: zipline transportation, slide transportation, and cable car transportation.

[0023] The present invention can achieve the following beneficial effects: 1. To address the issues of numerous, dispersed, and poorly accessible road conditions at mountainous photovoltaic construction sites, this invention establishes a centralized material supply point and multiple starting support frames on the work platform. Each starting support frame corresponds to a dispersed construction site, forming a multi-path parallel material supply structure. This structure allows for flexible scheduling of the material supply sequence based on the urgency of each construction site's needs, eliminating the need to rely on inter-site road transport for material transfer. This effectively avoids the limitations of single-path material supply and prevents material transport obstruction due to poor road conditions. Furthermore, the use of tower cranes enables rapid material hoisting onto the work platform. Combined with the continuous operation characteristics of cableway transport, which is unrestricted by terrain and road conditions, this significantly shortens the material turnaround time from preparation to delivery to each dispersed construction site, meeting the high-efficiency material supply requirements of large-scale mountainous photovoltaic construction scenarios.

[0024] 2. The winch of the rope traction device is equipped with a braking system and an overload protection device, which can accurately control the descent speed of the material basket and avoid swaying caused by excessive speed. The vibration sensor and exciter on the material basket form a closed-loop control, which can suppress the resonance risk during transportation in real time and reduce the damage to materials caused by vibration. For different types of materials such as bulk materials, component materials, and precision instruments, separate lifting tanks, lifting frames, and lifting boxes are designed to achieve specialized protective transportation and reduce the loss rate of fragile materials such as photovoltaic modules and precision instruments.

[0025] 3. Fully utilize the elevation difference between the centralized material supply point and the decentralized construction points, using gravitational potential energy as the main power for material transportation. The winch only needs to bear part of the weight and the return traction function of the empty hoist, which significantly reduces energy consumption compared to the fully powered transportation method. The centralized material preparation and multi-path transportation design reduces the secondary transfer links of materials in the construction area, reducing the input costs of labor and equipment. The material supply tower can be flexibly selected for installation based on the actual elevation difference between the centralized material supply point and the decentralized construction points, avoiding unnecessary infrastructure cost investment.

[0026] 4. The position adjustment mechanism of the lifting equipment drives the movable basket connector to move synchronously through the forward and reverse rotation of the lead screw, enabling adaptation to baskets of different sizes and improving the system's compatibility for transporting diverse materials. A worm gear reducer, combined with an electric wrench, simplifies the adjustment of the lifting point spacing, reduces manpower consumption, and improves adjustment efficiency. The cableway and support frame adopt a modular design, facilitating flexible arrangement according to the complex terrain features such as undulations and gullies in the construction area, enhancing the system's adaptability to mountainous environments.

[0029] This invention provides a centralized material supply point for supplying materials to multiple dispersed construction sites. The centralized material supply point is higher than the dispersed construction sites, utilizing the terrain elevation difference to provide a gravitational potential energy foundation for material transportation and reducing power consumption. A sliding cable 1 is installed between the centralized material supply point and the dispersed construction sites. The sliding cable 1 is made of high-strength steel wire rope to ensure that the load-bearing capacity meets the material transportation requirements. A sliding seat 2 is slidably installed on the sliding cable 1. The sliding seat 2 is equipped with a wear-resistant pulley system to reduce friction loss with the sliding cable 1. The sliding seat 2 is connected to a rope traction device 4 via a rope 3 to achieve movement control of the sliding seat 2. A lifting device 5 is installed on the sliding seat 2 to connect to a material basket 6, forming a complete material suspension transportation structure.

[0030] Furthermore, a feeding tower 7 is provided at the centralized feeding point, and a tower crane device 8 and a working platform 9 are provided on the feeding tower 7; the working platform 9 is connected to the cage ladder 14.

[0031] The tower crane device 8 is used to lift materials onto the working platform 9; The work platform 9 is used to store materials that need to be transported.

[0032] The feeding tower 7 is constructed using a steel or reinforced concrete structure, and its height is determined based on the actual elevation difference between the centralized feeding point and the decentralized construction points. The feeding tower 7 is equipped with a tower crane device 8 and a working platform 9. The tower crane device 8 is a small tower crane that meets the load requirements of mountain construction, and its working radius covers the ground material stacking area of ​​the centralized feeding point to the working platform 9. The tower crane device 8 is used to hoist materials onto the working platform 9, realizing the lifting of materials from the ground to the conveying starting point. The working platform 9 is a planar structure welded from steel profiles, equipped with guardrails and material limiting devices, used to store the materials to be conveyed and prevent materials from slipping on the platform.

[0033] Furthermore, the work platform 9 is equipped with multiple starting support frames 10, each starting support frame 10 corresponds to a distributed construction point, and each distributed construction point is equipped with an ending support frame 11. A sliding cable 1 connects the starting support frame 10 and the ending support frame 11.

[0034] The work platform 9 is equipped with multiple starting support frames 10. The starting support frame 10 is a rigid support structure and is fixedly connected to the work platform 9 by bolts. Each starting support frame 10 corresponds to a distributed construction point to ensure the uniqueness of the transportation path. Each distributed construction point is equipped with an ending support frame 11. The ending support frame 11 adopts the same structural form as the starting support frame 10 and is fixed to the solid ground around the construction point. A sliding cable 1 is connected between the starting support frame 10 and the ending support frame 11. When connecting, the sliding cable 1 is pre-tightened by a tensioning device to ensure that the sliding cable 1 does not sag significantly during transportation.

[0035] Furthermore, a rope traction device 4 is installed on the starting support frame 10. The rope traction device 4 includes a winch installed on the starting support frame 10. The winch is connected to the sliding seat 2 via a rope 3. When the centralized material supply point transports materials to the decentralized construction points, the winch is used to share part of the weight of the material basket 6, so that the material basket 6 slides down slowly. When the empty spreader 5 needs to return, the winch is used to pull the spreader 5 up.

[0036] A rope traction device 4 is installed on the starting support frame 10. The rope traction device 4 includes a winch installed on the starting support frame 10. The winch is equipped with a braking system and an overload protection device to ensure safe operation. The winch is connected to the sliding seat 2 via a rope 3. The rope 3 is a high-strength rope that matches the sliding cable 1. When the centralized material supply point is transporting materials to the decentralized construction point, the winch controls the release speed of the rope 3 to share part of the weight of the material basket 6, so that the material basket 6 slides down slowly at a speed of 0.5-1m / s, avoiding the material from shaking or being damaged due to excessive speed. When the empty lifting device 5 needs to return, the winch starts the rope winding mode, pulling the lifting device 5 to rise at the same speed, realizing the recycling of the equipment.

[0037] Furthermore, the lifting device 5 includes a hand chain hoist 501, which is connected to a load-bearing beam 502. The load-bearing beam 502 is equipped with a movable basket connector 503, which is used to connect the material basket 6.

[0038] The rated load of the hand chain hoist 501 is determined based on the maximum material weight. Its top hook is connected to the load-bearing structure of the sliding seat 2. The hand chain hoist 501 is connected to the load-bearing beam 502, which is made of high-strength alloy material to ensure overall load-bearing strength. The load-bearing beam 502 is equipped with a movable basket connector 503, which is a connecting seat structure with pulleys, used to connect the material basket 6, and can be flexibly adjusted according to the lifting point position of the material basket 6.

[0039] Furthermore, the load-bearing beam 502 is a T-shaped beam, and the movable suspended platform connector 503 is slidably installed on the load-bearing beam 502. The position of the movable suspended platform connector 503 is adjusted by the position adjustment mechanism 504.

[0040] The T-beam's cross-sectional structure provides better bending resistance; the movable suspended basket connector 503 is slidably installed in the T-slot of the load-bearing beam 502 via pulleys, resulting in low sliding resistance; the movable suspended basket connector 503 is positioned by the position adjustment mechanism 504 to achieve adaptable connection for suspended baskets 6 of different sizes.

[0041] Furthermore, the position adjustment mechanism 504 includes a lead screw, which is mounted on the load-bearing beam 502 via a bearing seat. The two ends of the lead screw are respectively provided with positive threads and negative threads, which are threadedly engaged with the two movable suspended platform connectors 503. The lead screw is driven to rotate by a worm gear reducer, and the rotation of the lead screw drives the movable suspended platform connectors 503 to move.

[0042] The lead screw adopts a high-precision trapezoidal thread structure and is installed at both ends of the load-bearing beam 502 through bearing seats. The bearing seats use deep groove ball bearings to ensure smooth rotation of the lead screw. The two ends of the lead screw are respectively provided with positive threads and negative threads, which respectively engage with the threaded holes at the bottom of the two movable basket connectors 503. The lead screw is driven to rotate by a worm gear reducer. The worm gear reducer has a self-locking function to prevent the lead screw from rotating on its own after adjustment. When the lead screw rotates, it drives the two movable basket connectors 503 to move closer or further away synchronously. The adjustment accuracy can reach ±5mm to ensure precise alignment with the lifting points of the material basket 6.

[0043] Furthermore, the worm gear reducer is equipped with a rotating head driven by an electric wrench.

[0044] The rotating head features a square interface design, making it compatible with commonly used electric wrenches. By driving the rotating head with an electric wrench, the rotation of the lead screw can be quickly adjusted, saving more time and effort compared to manual adjustment and improving construction efficiency.

[0045] Furthermore, the movable suspended basket connector 503 is connected to the material suspended basket 6 via a lifting rope or hook.

[0046] When the material basket 6 has an open structure, it is directly connected by hooks; when the material needs to be protected from falling, it is connected by high-strength lifting ropes with buckles at both ends to ensure a secure connection.

[0047] Furthermore, the material basket 6 is equipped with a vibration sensor and a vibrator.

[0048] Vibration sensors are installed at the center of gravity of the material basket 6 to collect vibration data in real time during transportation and transmit the data to the control terminal. The vibrator is installed at the bottom of the basket. When the vibration sensor detects that the vibration frequency exceeds the safety threshold or approaches the natural frequency of the basket, the vibrator starts to generate reverse vibration to offset some of the vibration energy and prevent the material from being damaged by resonance.

[0049] Furthermore, the material basket 6 can be a hanging tank, a hanging frame, or a hanging box, and the size and dimensions of the material basket 6 are determined by the material being lifted.

[0050] The material basket 6 can be a hanging tank, a hanging frame, or a hanging box. The size and dimensions of the material basket 6 are determined by the material being lifted. The hanging tank adopts a cylindrical structure with an inlet at the top and an outlet at the bottom, and is suitable for bulk materials such as sand, gravel, and cement. The hanging frame has a frame structure with multiple limit rods, and is suitable for long and narrow components such as photovoltaic brackets and photovoltaic panels. The hanging box has a closed box structure with internal cushioning pads, and is suitable for precision instruments or small tools such as inverters and meters.

[0051] Furthermore, the layout of centralized material supply points should include at least one of the following: Arrangement Method 1: When the centralized material supply point is higher than the decentralized construction point, and the height difference between the centralized material supply point and the decentralized construction point is sufficient for the material basket 6 to slide down under its own weight, no tower for raising the height is installed at the centralized material supply point. Arrangement Method 2: When the height difference between the centralized material supply point and the decentralized construction point is insufficient to allow the material basket 6 to slide down under its own weight, an extended tower is installed at the centralized material supply point.

[0052] The centralized material supply point can be arranged in at least one of the following ways: Arrangement 1: When the centralized material supply point is higher than the decentralized construction points, and the height difference between the centralized material supply point and the decentralized construction points is sufficient for the material basket 6 to slide down under its own weight (usually the height difference is not less than 5m), the centralized material supply point does not install a tower for raising the height, and directly uses the natural terrain height difference to achieve material transportation, thereby reducing construction costs; Arrangement 2: When the height difference between the centralized material supply point and the decentralized construction points is insufficient for the material basket 6 to slide down under its own weight, the centralized material supply point is equipped with a tower for raising the height. The height of the tower is determined according to the required supplementary height difference to ensure that the material can slide down smoothly under the action of gravity.

[0053] An operation method for a multi-point construction material supply system for mountain photovoltaic power generation includes the following: Material preparation and suspended platform selection: Based on the material demand plan of the dispersed construction sites, clarify the types (such as photovoltaic modules, brackets, cement, etc.), specifications (such as module size, bracket model) and quantity of materials to be transported; select a suitable material suspended platform 6 to ensure that the load-bearing capacity, structural form and material characteristics of the suspended platform are matched. Material hoisting at centralized feeding point: Operate the tower crane device 8 on the centralized feeding tower 7. Before starting, check whether the hoisting, luffing, and slewing mechanisms of the tower crane are normal and whether the limit devices are sensitive. Hoist the prepared materials from the ground material stacking area to the working platform 9 of the feeding tower. During the hoisting process, ensure that the lifting weight of the tower crane device 8 does not exceed the rated load. Control the hoisting speed and slewing angle through the tower crane operating handle to keep the materials stable during the hoisting process and avoid collisions with the feeding tower structure, other materials, or equipment. After the materials are hoisted to the working platform 9, arrange them neatly according to the conveying sequence and fix them with limit blocks. Cableway and lifting device connection and debugging: According to the number of the target dispersed construction points, start the designated starting support frame 10 on the work platform 9 accordingly; check whether the cableway 1 between the starting support frame 10 and the ending support frame 11 of the target construction point is taut, whether there is any damage or broken wires on the surface, and whether the sliding seat 2 slides smoothly on the cableway 1 without any jamming; install the lifting device 5 on the sliding seat 2, specifically: firmly connect the top hook of the hand chain hoist 501 to the load-bearing hole of the sliding seat 2, and then install the mobile suspended basket connector 503 on the T-shaped load-bearing beam. Inside the T-slot of 502; adjust the position of the movable suspended basket connector 503 through the position adjustment mechanism 504: connect the electric wrench to the rotating head of the worm gear reducer, start the electric wrench to drive the rotating head, and drive the lead screw to rotate; since the two ends of the lead screw are respectively provided with positive and negative threads, and are threadedly engaged with the two movable suspended basket connectors 503, the rotation of the lead screw can drive the two movable suspended basket connectors 503 to move closer or further away synchronously until the connection spacing is adjusted to match the lifting point spacing of the material suspended basket 6. After the adjustment is completed, turn off the electric wrench; Material basket connection and load check: Connect the material basket 6 to the lifting points using the movable basket connector 503 of the lifting device 5 with a lifting rope or hook. After connection, check whether each connection point is firm and reliable, and whether there is any risk of loosening or disengagement. After connection, operate the chain of the hand hoist 501 to finely adjust the height of the material basket 6 so that the material basket 6 is in a horizontal state to prevent the material from tilting and spilling. At the same time, check whether the connection of the rope 3 between the winch of the rope traction device 4 and the sliding seat 2 is tight, whether the rope clamp is installed in place, and whether the braking system of the winch is normal. Test the braking effect manually. Material delivery to dispersed construction points: Start the control switch of the rope traction device 4 on the starting support frame 10, and the winch starts working; Since the height of the centralized material supply point is higher than that of the dispersed construction points, the material basket 6 tends to slide down under the action of gravity. At this time, the winch controls the release length of the rope 3 through the internal braking system to share part of the weight of the material basket 6, so that the material basket 6 slides down the slide cable 1 at a slow and steady speed to the dispersed construction points; During the delivery process, a special person is arranged to monitor the data of the vibration sensor on the material basket 6 in real time through the control terminal. When the vibration frequency of the material basket 6 is detected to be close to the natural frequency (determined by the previous test), the vibrator is immediately started to perform reverse vibration fine adjustment to ensure that the material basket 6 runs stably along the slide cable (1) until it safely reaches the end support frame 11 of the dispersed construction points. At this time, the winch starts braking to stop the material basket 6 from sliding down. Empty basket return retrieval: Workers at the dispersed construction sites use the hand-operated hoist 501 to slowly lower the material basket 6 to the ground. After unloading the materials, they check whether the structure of the material basket 6 is intact and whether the lifting points and welds are damaged. Then, they start the winch winding mode of the rope traction device 4. The winch pulls the sliding seat 2, the empty lifting device 5, and the material basket 6 along the sliding cable 1 through the rope 3, returning to the starting support frame 10 of the centralized material supply point. After reaching the starting point, the winch is turned off, and the connection between the material basket 6 and the lifting device 5 is disconnected, completing one material supply cycle. Furthermore, the multi-construction-point alternating supply process: When materials need to be supplied to multiple dispersed construction points, multiple starting support frames 10 on the work platform 9, corresponding to different construction points, are used to prepare for material transportation at each construction point; the urgency of material needs at each construction point is collected through the construction management system, and the supply sequence is reasonably arranged according to the principle of "priority to critical path construction points and priority to urgent needs". For example, construction points for critical nodes of photovoltaic array installation are given priority over construction points for auxiliary facilities; after the material transportation at one construction point is completed, the transportation process for the next construction point is immediately started, realizing efficient and coordinated material supply at multiple points and improving the overall material supply efficiency; Furthermore, if the material basket 6 is transporting commercial cement, since cement is prone to clumping due to vibration during transportation, which affects the quality of use, the vibrator is continuously turned on during the transportation process of the material basket 6. The high-frequency vibration generated by the vibrator prevents the cement from clumping and ensures that the cement remains in a good loose state after arriving at the construction point. Furthermore, in material preparation and basket selection, if the material is bulk material, such as sand, gravel, bolts, etc., with small particles or large quantities, a hanging tank is selected as the material basket 6. The volume of the hanging tank is determined according to the single conveying volume, and the tank opening is equipped with a sealing cap to prevent material spillage. If the material is component material, such as photovoltaic brackets, photovoltaic panels, etc., with larger dimensions and relatively regular structures, a hanging frame is selected as the material basket 6. The frame size of the hanging frame matches the component size, and the component is fixed by a limit rod to prevent shaking during transportation. If the material is precision instrument or small tool, such as inverter, electrical tool, etc., which has high requirements for the transportation environment, a closed hanging box is selected as the material basket 6. The inside of the hanging box is lined with foam or rubber cushioning pads to avoid damage to the instrument due to collision, ensuring that the size and dimensions of the material basket 6 match the material being lifted.

[0054] A method for supplying construction materials at multiple points in mountain photovoltaic power generation includes the following steps: Taking into account the topographical variations (such as slope and altitude difference) of the mountainous photovoltaic power generation construction area, the distribution density of photovoltaic construction sites (such as the number of construction sites per square kilometer), and the total demand for photovoltaic modules, brackets, and other materials, at least one centralized material supply point should be planned. The location of the centralized material supply point should take into account the convenience of material transportation (such as proximity to transportation roads), terrain stability, and coverage of the construction sites. The layout of the centralized material supply point should include at least one of the following: Arrangement Method 1: When the centralized material supply point is higher than the decentralized construction points, and the height difference between the centralized material supply point and the decentralized construction points is sufficient for the material basket to slide down under its own weight (after calculation, the component of gravity is greater than the friction force), the centralized material supply point does not need to install a tower for increasing its height, and directly utilizes the advantages of the natural terrain. Arrangement Method 2: When the height difference between the centralized material supply point and the decentralized construction point cannot meet the requirement that the material basket 6 can slide down by its own gravity, the centralized material supply point is equipped with an increased tower. The height of the tower is determined by mechanical calculation to ensure that the material can be conveyed down by gravity. Materials are transported from the production base or warehouse to the ground material storage area of ​​the centralized material supply point by transport vehicles. During the transportation process, protective measures are taken according to the characteristics of the materials (such as shockproof for component transportation and moistureproof for cement transportation). From the centralized material supply point, materials are supplied to various decentralized construction points through a pre-set conveying device to reduce the secondary transfer of materials in the construction area. The material transportation method includes at least one of the following: zipline transportation, slide transportation, and cable car transportation. Among them, zipline transportation is suitable for areas with complex terrain and large spans; slide transportation adopts a U-shaped trough structure and is suitable for scenarios with gentle slopes and bulk or small components; cable car transportation adopts a track-type cable car and is suitable for situations with large transportation volume and heavy materials. A single or combined transportation method can be selected according to the actual terrain of the construction area and the material requirements.
