Description

Technical Field

[0001] This application belongs to the field of photovoltaic system construction, and specifically relates to a mountain photovoltaic module cableway transportation system. Background Technology

[0002] In the construction of photovoltaic power stations in mountainous areas, the transportation of materials such as photovoltaic modules has long faced the challenge of complex terrain. Existing transportation methods mainly include building temporary construction roads and using vehicles or manpower for transportation; using drones for aerial hoisting; setting up fixed guide rails or cableways along the mountainside; and relying entirely on construction workers to carry and transport the materials.

[0003] Among them, mountain road construction is costly, time-consuming, and causes significant damage to the ecological environment, and many areas have explicitly banned the construction of roads through mountains; drones are expensive to lift equipment and are easily affected by weather factors such as wind, resulting in limited transportation capacity; traditional guide rails or cableways require the pre-construction of special towers and foundations, resulting in low utilization and low transportation efficiency; manual carrying poses significant safety hazards on steep slopes and has extremely low personnel utilization efficiency.

[0004] The aforementioned existing transportation methods all share a common technical problem: the lack of an economical, efficient, and safe material transfer solution that can be quickly constructed in complex mountainous terrain using readily available common materials (such as trees, rocks, existing photovoltaic supports, and ordinary steel wire ropes) and can adaptively adjust transportation power according to load changes. Specifically, existing technologies either rely on heavy machinery or a large amount of civil engineering (such as road construction and tower foundation pouring), or on expensive and environmentally sensitive specialized equipment (such as drones), or rely entirely on manpower, making it impossible to achieve a transportation mode of "using local materials, rapid assembly, and adaptive speed adjustment".

[0005] Therefore, there is an urgent need for a cableway transportation system and its construction method that can simplify the construction process, reduce material requirements, and have load-adaptive capabilities, so as to adapt to the dispersed and variable construction scenarios of mountain photovoltaic power stations.

[0013] Furthermore, when the force sensor detects that the load weight is less than or equal to the first threshold, the main control unit controls the shift drive assembly to switch to an acceleration gear with a speed ratio of the first speed ratio; When the force sensor detects that the load weight is greater than the first threshold and less than or equal to the second threshold, the main control unit controls the shift drive assembly to maintain the direct drive gear with the speed ratio of the second speed ratio.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] This application relates to the field of photovoltaic power plant construction technology, and in particular to a mountain photovoltaic module cableway transportation system and its transportation method.

[0025] In the construction of mountain photovoltaic power stations, the main methods of transporting materials such as photovoltaic modules include the following: (1) Construct temporary construction roads and use vehicles or manpower for transportation; (2) Using drones for aerial hoisting; (3) Install fixed guide rails or cableways along the hillside; (4) Relying on construction workers to carry and transport.

[0026] Among them, mountain road construction is costly, time-consuming and causes great damage to the ecological environment. Many areas have explicitly banned the construction of roads through mountains. Drones are expensive to lift equipment and are easily affected by weather factors such as wind, resulting in limited transportation capacity. Traditional guide rails or cableways require the pre-construction of special towers and foundations, resulting in low utilization and low transportation efficiency. Manual carrying poses significant safety hazards on steep slopes and has extremely low personnel utilization efficiency.

[0027] In summary, all the existing transportation methods mentioned above share a common technical problem: the lack of an economical, efficient, and safe material transfer solution that can be quickly constructed using readily available common materials in complex mountainous terrain, and that can adaptively adjust transportation power according to load changes.

[0028] To address the aforementioned issues, this application provides a mountain photovoltaic module cableway transportation system, which includes a first support component 1, a second support component 2, a flexible traction component, a shift-type drive component 3, and a guide and anti-detachment component 5.

[0029] Please see Figure 1The first support component 1 includes a first tower 11 installed on the edge of the road and a self-weight locking base 12 set at the bottom of the first tower 11. After the self-weight locking base 12 is placed on the ground, it generates a self-locking torque by using its own weight, so that the first tower 11 becomes tighter and tighter when subjected to force, and can remain stable without additional ground anchors or concrete foundations.

[0030] With the above structure, construction workers do not need to carry heavy tools or carry out complex civil construction. They only need to move the first tower 11 to the predetermined position and place it on a flat ground to complete the rapid deployment of the first support point, which greatly reduces the threshold for system construction and construction cycle.

[0031] Further, see Figure 3 The self-weight locking base 12 includes a support frame 121 and a movable sleeve 122 disposed on the surface of the support frame 121. The first tower 11 can move linearly inside the movable sleeve 122, thereby realizing rapid adjustment of the tower height. The bottom of the self-weight locking base 12 is also provided with a height adjustment mechanism 4. The bottom of the self-weight locking base 12 can be connected to a plate-like structure to set multiple height adjustment mechanisms to ensure force balance. The height adjustment mechanism 4 can adjust the height of the self-weight locking base 12 within a preset range to adapt to the elevation difference of different terrains. The height adjustment mechanism can be a mechanical adjustment mechanism, such as consisting of a slide rod, a slide sleeve, and a fixing bolt that can fix the position of the slide rod in the slide sleeve. It can also be composed of a hydraulic rod or a cylinder driven by electricity. Those skilled in the art can use conventional lifting devices to achieve height adjustment, which will not be elaborated here.

[0032] The second support component 2 is installed on the surface of the existing photovoltaic panel support 6. Specifically, the second support component 2 includes a second tower 21. The upper part of the second tower 21 is provided with an installation part 22 for detachable connection with the existing photovoltaic panel support 6. The installation part 22 can be connected by detachable methods such as clamps, buckles, or bolts, so that the second tower 21 can be directly fixed using the existing photovoltaic structure support at the photovoltaic power station site without the need to build an additional independent support structure. The lower part of the second tower 21 is provided with a pile foundation 7 for fixing to the ground. The advantage of this design is that it makes full use of the existing structural components at the construction site, reduces the amount of material transportation and foundation construction, and further reflects the technical concept of using local materials and rapid assembly.

[0033] The flexible traction component is disposed between the first support component 1 and the second support component 2, and can form a transportation channel between the first support component 1 and the second support component 2.

[0034] The flexible traction component can be made of common flexible wire materials such as steel wire rope and steel strand that are readily available at the construction site. The two ends of the flexible traction component are detachably connected to the upper ends of the first support component 1 and the second support component 2, respectively, to form a suspended transportation channel for carrying photovoltaic modules and other materials along the hillside.

[0035] The shift drive assembly 3 is connected to the flexible traction member and is used to drive the flexible traction member to reciprocate between the first support assembly 1 and the second support assembly 2 at at least two different speeds.

[0036] Specifically, the shift drive assembly 3 includes a power source, a transmission, and a drive wheel. The output end of the power source is connected to the input end of the transmission, and the output end of the transmission is connected to the drive wheel. The drive wheel engages with or rubs against a flexible traction member. In a preferred embodiment of this application, the power source is a motorcycle engine, which has the advantages of low cost, light weight, adaptability to harsh mountain environments, and ease of acquisition and maintenance.

[0037] The transmission has at least two gear ratio switching mechanisms, one of which is a speed-increasing gear and the other is a direct-drive gear. Preferably, the speed ratio of the speed-increasing gear can be 1:3, and the speed ratio of the direct-drive gear can be 1:1. It should be noted that the 1:3 speed-increasing gear means that for every 1 revolution of the input shaft, the output shaft rotates 3 times, and the output speed is 3 times the input speed, which is suitable for fast transportation under light loads; the 1:1 direct-drive gear means that the input shaft and output shaft rotate at the same speed, with no speed-increasing effect, but the output torque is the maximum, which is suitable for stable transportation under heavy loads.

[0038] Furthermore, the shift drive assembly 3 also includes a control assembly, which includes a main control unit and a force sensor.

[0039] A force sensor is installed at the output end of the transmission or on the axle of the drive wheel to detect the output torque of the transmission or the tension of the flexible traction component. The main control unit controls the transmission to shift gears through the shift actuator based on the signal detected by the force sensor. In one embodiment, when the force sensor detects that the load weight is less than or equal to a first threshold, the main control unit controls the shift drive assembly 3 to engage a speed-increasing gear with a first speed ratio; when the force sensor detects that the load weight is greater than the first threshold and less than or equal to a second threshold, the main control unit controls the shift drive assembly 3 to maintain a direct drive gear with a second speed ratio.

[0040] Through the above-mentioned adaptive shift control design, the system can automatically adjust the transport speed according to the load change without manual intervention in shifting, which not only ensures the transport efficiency under light load conditions, but also ensures sufficient power under heavy load conditions, significantly improving the overall transport efficiency.

[0041] See also Figure 2The guide anti-detachment component 5 is disposed on the first support component 1 and / or the second support component 2 and is in contact with the flexible traction member. It can constrain the movement trajectory of the flexible traction member between the first support component 1 and the second support component 2 and prevent it from detaching from the guide anti-detachment component 5.

[0042] Specifically, the guide anti-detachment component 5 includes a limiting clamp 51 that can be installed on the first support component 1 and the second support component 2, and a pulley 52 disposed in the limiting clamp 51.

[0043] The pulley 52 has at least two guide grooves on its surface, and the flexible traction component is accommodated in the guide grooves. The cross-section of the guide groove can be V-shaped, U-shaped, or arc-shaped. When the flexible traction component is subjected to lateral force or vibration during transportation, the sidewall of the guide groove can guide the flexible traction component back to the center of the groove bottom, forming a self-centering effect. At least two guide grooves simultaneously constrain the same flexible traction component, forming a multiple locking mechanism. Even if the flexible traction component is dislodged from one guide groove under violent shaking, it will still be constrained by the other guide groove, reducing the risk of complete derailment. This guide anti-derailment component 5 effectively prevents the flexible traction component from dislodging from the pulley 52 due to shaking, swaying, or vibration during transportation, avoiding transportation interruption or safety accidents caused by derailment of the traction cable. Combined with the height-adjustable design of the first support component 1 and the detachable connection between the second support component 2 and the existing photovoltaic structure support, the system can still maintain a stable transportation channel in complex mountainous terrain, significantly improving the operational safety of construction personnel when transporting photovoltaic modules on steep mountain slopes.

[0044] In summary, the mountain photovoltaic module cableway transportation system provided in this application features a first support component 1 consisting of a first tower 11 equipped with a self-weight locking base 12, and a second support component 2 that can be installed on the surface of an existing photovoltaic panel support 6. The flexible traction component, the shifting drive component 3, and the guide anti-detachment component 5 are all detachably connected. This structural design allows construction workers to quickly complete the system setup without complex civil engineering or the construction of dedicated roads, utilizing only existing structures commonly found on-site (i.e., the photovoltaic panel support 6) and simple tools. Furthermore, the entire system can be disassembled, transferred, and reused, effectively solving the problems of high construction costs, long construction periods, severe ecological damage, and reliance on heavy machinery or specialized equipment in existing technologies. This significantly reduces the construction threshold and overall cost of material transportation systems.

[0045] Please see Figure 4 The following describes the typical working process of this system, namely the mountain photovoltaic module cableway transportation method of this application.

[0046] S1. System Setup.

[0047] This step aims to install the first support assembly 1 at the edge of the road. The first support assembly 1 includes a first tower 11, and the bottom of the first tower 11 is provided with a self-weight locking base 12.

[0048] S1-1. Construction workers can select a flat ground at the edge of the road and move the first tower 11 together with its self-weight locking base 12 to this location. Place the self-weight locking base 12 on the ground. Since the self-weight locking base 12 relies on its own weight to lock, there is no need to fix it with ground anchors or pour concrete. It is only necessary to ensure that the ground is relatively flat to complete the setting of the first support point.

[0049] S1-2. Insert the first tower 11 into the movable sleeve 122 of the self-weight locking base 12, so that the height of the first tower 11 can be adjusted in a straight line within the movable sleeve 122, and the height of the self-weight locking base 12 can be adjusted within a preset range by the height adjustment mechanism 4 provided at the bottom of the self-weight locking base 12.

[0050] S1-3. Install the second support component 2 onto the surface of the existing photovoltaic panel support 6. The second support component 2 includes a second tower 21, the upper part of which is provided with an installation part 22 for detachable connection with the existing photovoltaic panel support 6, and the lower part of which is provided with a pile foundation 7.

[0051] S1-4. Construction workers locate existing photovoltaic structure supports in the valley area and detachably connect the upper mounting part 22 of the second tower 21 to the photovoltaic structure support, such as by using clamps or bolts to tighten it. The pile foundation 7 of the lower part of the second tower 21 is simply fixed to the ground, such as by inserting the tip of the pile foundation 7 into the soil or placing it in a rock pit. During this process, construction workers do not need to carry special tools or perform complex measurements and positioning. The entire support point can be set up in a short time.

[0052] S1-5. A flexible traction component is placed between the first support component 1 and the second support component 2 to form a transportation channel. Construction workers can use readily available materials on site, such as steel wire rope and steel strand, as the flexible traction component. One end of the flexible traction component is detachably fixed to the upper end of the first support component 1, and the other end is detachably fixed to the upper end of the second support component 2, forming a suspended transportation channel connecting the road edge and the valley area. The length of the flexible traction component can be adjusted according to the actual distance between the two locations, and any excess can be rolled up and stored or cut off.

[0053] S1-6. Connect the shift-type drive assembly 3 to the flexible traction component. Construction personnel move the shift-type drive assembly 3 (including the power source, transmission, and drive wheel) to the vicinity of the first support assembly 1 or the second support assembly 2. Using brackets or mounting bases, fix the drive assembly to a stable surface or an auxiliary support connected to the tower. Engage or frictionally contact the drive wheel with the flexible traction component to ensure reliable movement of the flexible traction component. Place the guide anti-detachment component 5 on the first support assembly 1 and / or the second support assembly 2, ensuring contact between the flexible traction component and the guide anti-detachment component 5.

[0054] S1-7. The construction personnel fix the guide anti-detachment component 5 (including the limiting clamp 51 and the pulley 52 provided in the limiting clamp 51) to the top or side of the first support component 1 and / or the second support component 2, and then pass the flexible traction member through the guide groove on the pulley 52 so that the flexible traction member is always constrained by the guide groove during the movement.

[0055] Once S1 is completed, the entire cableway transportation system is finished and ready for material transport operations. The core advantage of this construction method is: First, all construction steps can be completed without the use of heavy machinery or complex civil engineering. Construction workers only need simple tools (such as wrenches) to complete all operations. Secondly, both the support point materials (existing structures or rods) and the flexible traction materials (flexible wires) can be obtained locally from the construction site, reducing material procurement and transportation costs. Third, the shift drive assembly 3 and the guide anti-detachment assembly 5 are modular components that can be installed, making installation simple and ensuring the reliability of the core functions of the system. Fourth, the entire construction process does not require highly specialized skills from construction workers; ordinary photovoltaic power station construction workers can quickly master and complete the construction.

[0056] S2, Start transportation.

[0057] The shift drive assembly 3 is activated, driving the flexible traction member to reciprocate between the first support assembly 1 and the second support assembly 2 at at least two different speeds.

[0058] Specifically, the power source is started, and power is transmitted to the drive wheels via the transmission. The drive wheels drive the flexible traction component to move in a cyclical motion. Construction workers attach the photovoltaic modules to the flexible traction component, which then transports the photovoltaic modules from the location of the first support component 1 to the location of the second support component 2.

[0059] S3, Adaptive shift control.

[0060] The load is detected by the control component located in the shift drive assembly 3, and the speed gear of the shift drive assembly 3 is automatically switched according to the detected load.

[0061] Specifically, the control components include a main control unit and a force sensor. The force sensor is located at the output end of the transmission or on the axle of the drive wheel, and is used to detect the output torque of the transmission or the tension of the flexible traction component. The force sensor sends the detected signal to the main control unit, which determines the current load weight based on the received signal and controls the transmission to shift gears through the shift actuator.

[0062] When the load weight is determined to be less than or equal to 300 kg, the main control unit controls the transmission to switch to a speed-increasing gear with a speed ratio of 1:3, increasing the speed of the drive wheels and allowing the flexible traction component to move at a faster speed, achieving rapid transport for light loads. When the load weight is determined to be greater than 300 kg but less than or equal to 500 kg, the main control unit controls the transmission to remain in a direct drive gear with a speed ratio of 1:1, causing the drive wheels to rotate synchronously with the power source output, maximizing the output torque, and allowing the flexible traction component to move at a slower but more stable speed, achieving reliable transport for heavy loads. Throughout the transport process, the guide anti-detachment component 5 constantly constrains the movement trajectory of the flexible traction component, preventing it from detaching from the pulley 52 due to vibration or swaying, ensuring the safe operation of the transport.

[0063] Once a batch of photovoltaic modules has been transported or the construction task is completed, the construction personnel can disassemble and retrieve each module one by one in the reverse order of assembly. Because the first support module 1, the second support module 2, the flexible traction component, the shift-type drive module 3, and the guide and anti-detachment module 5 are all connected in a detachable manner, the entire system can be completely disassembled into multiple independent parts, facilitating transportation, storage, or transfer to the next construction site for reuse. The advantage of this design is that the system possesses excellent mobility and reusability, further reducing the overall cost of long-term use.

[0064] In other embodiments, the flexible traction component is not limited to steel strand, but can also be flexible wire with sufficient tensile strength, such as nylon rope or braided tape. The height adjustment method of the first support component 1 and the second support component 2 can adopt a sleeve telescopic structure or a gear rack structure. The power source of the shift drive component 3 is not limited to a motorcycle engine, but can also be a small gasoline engine, electric motor, or diesel engine, as long as it has the ability to output rotational power. The speed ratio switching mechanism in the transmission can adopt a known transmission structure in the art, such as a sliding gear type, a synchronizer type, or a planetary gear type. The force sensor can adopt a strain gauge torque sensor, a piezoelectric force sensor, or a magnetoelastic torque sensor, or other conventional force detection elements in the art. The main control unit can adopt a microcontroller, a programmable logic controller, or an embedded microprocessor, or other conventional control devices in the art. The shifting actuator can adopt an electromagnet, a stepper motor, or a hydraulic cylinder, or other conventional actuators in the art, to drive the shift fork or synchronizer in the transmission to complete the gear shift. The cross-sectional shape of the guide groove is not limited to V-shape, but can also adopt a U-shape, trapezoidal shape, or arc shape, or other cross-sectional shapes that can constrain the flexible traction component.

[0065] Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
