Description

Technical Field

[0001] This invention relates to the field of hoisting equipment technology, and more specifically, to an auxiliary hoisting device and hoisting method for mountain photovoltaic installation. Background Technology

[0002] As the global energy structure accelerates its transition to clean and low-carbon energy, solar photovoltaic power generation, as a core component of renewable energy, continues to expand in scale. Mountainous and hilly areas, with their vast unused land and suitable sunlight conditions, are gradually becoming key areas for photovoltaic power plant development. Although the construction of mountain photovoltaic power plants can effectively revitalize idle land resources, the transportation and installation of photovoltaic panels face numerous technical bottlenecks due to terrain limitations, becoming key factors restricting construction efficiency and safety.

[0003] Currently, during the installation of photovoltaic systems in mountainous areas, the steep slopes and deep ravines make it difficult to move medium and large-sized hoisting equipment, hindering its relocation and access to the core work area. The transportation and hoisting of photovoltaic panels still rely on a combination of traditional equipment and manual labor. In the "last mile" of transportation for photovoltaic installation in mountainous areas, manual handling is not only inefficient and labor-intensive, but also poses significant safety hazards.

[0004] To solve the "last mile" transportation problem, drones, with their excellent obstacle-crossing ability, flexible maneuverability and good adaptability to complex terrain, have gradually become an important tool for transporting photovoltaic materials in mountainous areas.

[0005] However, the current mainstream method for transporting photovoltaic panels by drones largely relies on the cross-tying and securing of cables, followed by manual binding and unbinding. This method has revealed significant shortcomings in practical applications: First, the manual binding and unbinding of cables is time-consuming, severely limiting transportation efficiency; second, the drone needs to hover in the air during binding and unbinding, consuming its battery power and significantly reducing the number of times it can be used, increasing the frequency of battery replacements, and further reducing the efficiency of photovoltaic material transportation; third, this method requires highly skilled operators in binding, and insecure binding can easily cause the photovoltaic panels to slip, tilt, or even fall during transportation, posing a risk of damage and on-site safety hazards.

[0006] Therefore, we propose an auxiliary hoisting device and hoisting method for mountain photovoltaic installations to solve the above-mentioned technical problems. Summary of the Invention

[0007] In order to solve the technical problems existing in the prior art, the present invention proposes an auxiliary hoisting device and hoisting method for mountain photovoltaic installation.

[0008] This invention is achieved through the following technical solution:

[0009] An auxiliary hoisting device for mountain photovoltaic installation includes:

[0010] The spare plate box has an opening on its top surface. The spare plate box is equipped with a reciprocating lifting mechanism and a drive assembly for driving the reciprocating lifting mechanism. The reciprocating lifting mechanism is arranged with multiple sets of bearing units along the vertical direction. The spare plate box has an operation window on one side of the bearing unit.

The bottom of the connecting frame and the plate supports are provided with quick-release rods around the perimeter, and the top surface of the plate supports is provided with quick-release seats that match the quick-release rods around the perimeter.

[0012] In a further technical solution, the quick-release lever includes a support rod, a pin, an upper truncated cone, and a lower truncated cone. The support rod, pin, and lower truncated cone are arranged coaxially along the same axis from top to bottom. The diameter of the pin is smaller than that of the support rod. The lower truncated cone and the upper truncated cone are the same size and face each other. The upper truncated cone is movably sleeved on the pin. The upper truncated cone and the lower truncated cone are strong magnets with opposite magnetic poles. The quick-release base includes a sleeve. Two insertion holes are symmetrically opened through the outer periphery of the sleeve. A locking pin is slidably installed in the insertion holes. The two ends of the locking pin extend to the outer and inner sides of the sleeve, respectively, and are respectively provided with a limiting block and a locking block. The locking block has an inclined surface on the side facing the inside of the sleeve and cooperates with the upper truncated cone and the lower truncated cone. A return spring is sleeved on the locking pin. The two ends of the return spring abut against the locking block and the inner wall of the insertion hole, respectively.

[0013] In a further technical solution, the top surface of the plate holder is provided with a plate groove, and after the quick-release rod is inserted into the quick-release seat, the limiting block at one end of the locking pin extends above the plate groove.

[0014] In a further technical solution, the reciprocating lifting mechanism includes two symmetrically arranged spare plate conveyor belts in the spare plate box. Each spare plate conveyor belt includes multiple vertically spaced rotating rollers and a chain belt wound around the rotating rollers. The carrying unit is connected to the chain belt. The driving component is in transmission cooperation with both spare plate conveyor belts and drives the spare plate conveyor belts to move upward synchronously.

[0015] In a further technical solution, the bearing unit includes two support plates, which are respectively disposed on the chain belts on both sides and perpendicularly connected to the chain belts. The two ends of the plate holder are respectively placed on the support plates on the same plane on the two spare plate conveyor belts.

[0016] In a further technical solution, the drive assembly includes a drive motor, a drive wheel, a first driven wheel, a second driven wheel, a drive gear, and a reversing shaft. The drive wheel and the drive gear are coaxially fixedly sleeved on the output shaft of the drive motor. The first driven wheel and the second driven wheel are respectively fixedly sleeved on the rotating shafts of the rotating rollers on both sides. The drive wheel is drivenly connected to the first driven wheel through a first transmission belt. The reversing shaft is rotatably mounted on a spare plate box. A reversing gear and a reversing wheel are coaxially fixedly sleeved on the reversing shaft. The reversing gear meshes with the drive gear. The reversing wheel is drivenly connected to the second driven wheel through a second transmission belt.

[0017] In a further technical solution, the spare plate box is provided with a disassembly plate at the bottom of the operation window.

[0018] In a further technical solution, the bottom of the sleeve is provided with an outer expansion cylinder.

[0019] In a further technical solution, the bottom of the spare plate box is provided with a tracked moving base, and a plate trolley is suspended and connected to the rear of the spare plate box.

[0020] An auxiliary hoisting method for mountain photovoltaic installation, based on an auxiliary hoisting device for mountain photovoltaic installation as described above, includes the following steps:

[0021] S1. Connect the mounting frame to the drone;

[0022] S2. Install photovoltaic panels into the empty panel mounting brackets and place them onto the load-bearing units in the spare panel box through the operation window;

[0023] S3. The drone hovers above the spare plate box, starts the drive motor to drive the spare plate conveyor belt to transport the plate support upwards, and docks with the plate support through the connecting frame. Whether to dock with the plate support depends on the lifting capacity of the drone.

[0024] S4. After docking is completed, the drone flies to the destination, descends the altitude, and the quick-release seat and quick-release rod detach, quickly placing the plate bracket at the destination. At the same time, the spare plate box moves towards the destination via the tracked moving base.

[0025] S5. Connect to an available pallet rack at the destination and transport it back to the spare pallet box.

[0026] S6, jump to S2, until the day's work is finished.

[0027] The technical solution of the present invention has at least the following beneficial effects:

[0028] 1. The spare panel box of this invention has the capacity to store multiple sets of carrying units in batches. One spare panel box can be used in conjunction with multiple drones to work together, creating a new transportation mode that combines cyclic loading and quick loading and unloading. This not only reduces the labor intensity of operators and avoids the safety hazards caused by improper manual bundling operations, but also effectively shortens the time for drones to hover and wait and for a single operation, reduces the frequency of battery replacement, realizes continuous and efficient transportation of photovoltaic panels, and improves operational efficiency.

[0029] 2. The mounting brackets of this invention can be stacked and connected to each other, adapting to drones with different carrying capacities. Single or multiple sets of mounting brackets can be flexibly selected for stacking and hoisting, effectively increasing the single transport capacity of the drone and avoiding waste of transport capacity.

[0030] 3. During the drone hoisting operation, the present invention can simultaneously advance the movement of the spare pallet box, which can gradually shorten the distance of the drone's round-trip flight, thereby reducing the drone's energy consumption and battery replacement frequency, further improving the operation efficiency, and is particularly suitable for the construction needs of complex terrains such as mountains and hills.

[0031] 4. The quick-release structure of the present invention, while completing the docking, locks the pin to extend outward by a distance so that the limiting block at its end extends to the upper area of ​​the mounting slot, thereby abutting the photovoltaic panel in the mounting slot, improving the stability of the photovoltaic panel, and preventing the photovoltaic panel from vibrating due to force majeure or even falling off the mounting bracket.

Detailed Implementation

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Example:

[0043] See Figures 1-7 This invention provides an auxiliary hoisting device for mountain photovoltaic installation, comprising:

[0044] The spare plate box 1 has an opening on its top surface. The spare plate box 1 is equipped with a reciprocating lifting mechanism and a drive component that drives the reciprocating lifting mechanism. The reciprocating lifting mechanism is arranged with multiple sets of bearing units along the vertical direction. The spare plate box 1 has an operation window 2 on one side of the bearing unit.

[0045] The lifting device includes a connecting frame 3 and multiple plate support brackets 4. The connecting frame 3 is used to connect the drone, and the plate support brackets 4 are placed on the bearing unit. The bottom of the connecting frame 3 and the plate support brackets 4 are provided with quick-release rods 6 around the perimeter, and the top surface of the plate support brackets 4 is provided with quick-release seats 5 that match the quick-release rods 6 around the perimeter.

[0046] The specific working principle of this auxiliary hoisting device is as follows:

[0047] First, the operator securely connects the connecting frame 3 in the lifting device to the bottom of the drone, forming an aerial lifting unit. Then, the photovoltaic panels to be transported are smoothly placed into the mounting bracket 4. Next, through the operating window 2 on the side of the spare panel box 1, the mounting brackets 4 with pre-installed photovoltaic panels are placed one by one onto the carrying units inside the spare panel box 1. Since the spare panel box 1 has multiple sets of carrying units arranged vertically, it can simultaneously store multiple mounting brackets 4 with pre-installed photovoltaic panels, forming a batch-ready-to-ship shelf, enhancing the potential for continuous operation. Then, the drive assembly is activated, which drives the reciprocating lifting mechanism to transport the carrying units upwards until the mounting brackets 4 on them are delivered to the top opening of the spare panel box 1. At this point, the drone hovers at the top opening of the spare panel box 1, and precisely aligns itself with the quick-release rods 6 pre-installed around the bottom of the connecting frame 3 and the matching quick-release seats 5 around the top of the mounting brackets 4. Leveraging the quick-release structure, the connecting frame 3 and the mounting plate support are locked together. This process requires no manual assistance and only a brief hovering of the drone is needed to complete the connection, achieving a rapid and reliable connection of the mounting plate support 4 and effectively shortening the docking time. If the drone's carrying capacity allows, stacking docking can also be performed. That is, based on a set of docked mounting plate supports 4, the quick-release rod 6 at the bottom of the mounting plate support 4 can be used to dock with the quick-release seat 5 on the top surface of the next mounting plate support 4, thereby achieving the stacking and hoisting of multiple sets of mounting plate supports 4, effectively increasing the drone's single transport capacity and improving operational efficiency. After docking, the drone, carrying the mounting plate support 4, flies to the destination of the mountain photovoltaic installation operation with its flexible obstacle-crossing ability. Upon arrival, the drone slowly descends its flight altitude, allowing the lowest mounting plate support 4 to make stable contact with the ground, and quickly unlocks and separates from the quick-release seat 5 and quick-release rod 6, achieving rapid unloading of the mounting plate support 4. After unloading, the drone can fly back to the upper plate position of the spare plate box 1 to prepare for the next round of hoisting, achieving continuous and rapid operation. The entire operation requires no prolonged drone hovering, significantly reducing power consumption. Due to the device's cyclical operation design, once the mounting bracket 4 is unloaded, the empty mounting bracket 4 at the destination can be quickly docked and retrieved to the mounting position for subsequent repeated loading of photovoltaic panels, forming a closed-loop operation process. Compared to traditional manual bundling and disassembly methods, this invention, through improvements to the lifting equipment and the pre-processing unit of the spare panel box 1, reduces reliance on manual bundling, constructing a new transportation mode combining cyclic loading and rapid loading / unloading. By dividing the lifting equipment into two quickly dockable and detachable connecting frames 3 and mounting brackets 4, and pre-preparing multiple mounting brackets 4 to be hoisted before hoisting and docking, multiple drones can be quickly docked. This not only reduces the labor intensity of operators and avoids safety hazards caused by improper manual bundling operations, but also shortens the drone hovering and waiting time and the time per operation, reduces battery replacement frequency, and increases the number of transports per operation.In addition, with the help of standardized connecting frames 3 and plate mounting brackets 4, drones with different carrying capacities can be flexibly connected to different numbers of plate mounting brackets 4, which effectively improves the transportation efficiency of the "last mile" of photovoltaic installation in mountainous areas and perfectly adapts to the construction needs of complex terrains such as mountains and hills.

[0048] In one specific implementation, see Figure 4 , Figure 5 and Figure 6 The quick-release lever 6 includes a support rod 61, a pin 62, an upper frustum 63, and a lower frustum 64. The support rod 61, pin 62, and lower frustum 64 are arranged coaxially along the same axis from top to bottom. The diameter of the pin 62 is smaller than that of the support rod 61. The lower frustum 64 and the upper frustum 63 are the same size and are arranged facing each other. The upper frustum 63 is movably fitted onto the pin 62. The upper frustum 63 and the lower frustum 64 are strong magnets with opposite magnetic poles. The quick-release base 5 includes a sleeve 51, the outer periphery of which is symmetrical. Two insertion holes 52 are provided through the sleeve. A locking pin 53 is slidably installed in the insertion hole 52. The two ends of the locking pin 53 extend to the outer and inner sides of the sleeve 51, respectively, and are respectively provided with a limiting block 54 and a locking block 55. The locking block 55 has an inclined surface on the side facing the inside of the sleeve 51 and cooperates with the upper truncated cone 63 and the lower truncated cone 64. A return spring 56 is sleeved on the locking pin 53. The two ends of the return spring 56 abut against the locking block 55 and the inner wall of the insertion hole 52, respectively.

[0049] When the connecting frame 3 and the plate support 4 are docked, the drone drives the connecting frame 3 to slowly descend, thus hovering at the top opening of the spare plate box 1. At the same time, the drive component is activated, the reciprocating lifting mechanism operates, and the plate support 4 is transported upward, so that the quick-release rod 6 is inserted into the quick-release seat 5. As the plate support 4 continues to rise, the conical surface of the lower truncated cone 64 contacts the inclined surface of the locking block 55 and generates a squeezing force, pushing the locking pins 53 on both sides to slide outward along the insertion hole 52 until the locking block 55 passes through the lower truncated cone 64. Under the elastic force of the return spring 56, the locking block 55 is inserted into the gap between the upper truncated cone 63 and the lower truncated cone 64, abutting against the surface of the pin 62, and the docking is completed. Specifically, the upper truncated cone 63 and the lower truncated cone 64 are strong magnets with opposite magnetic poles. Under normal conditions, the weight of the upper truncated cone 63 is less than the magnetic force on the upper truncated cone 63, so there is a gap between them, which allows the locking block 55 to be inserted during docking. After insertion, the drone ascends. Under the influence of gravity, the top surface of the lower truncated cone 64 abuts against the bottom surface of the locking block 55, preventing the plate support 4 from falling downwards. This achieves a secure lock between the connecting frame 3 and the plate support 4, providing reliable protection for subsequent hoisting. When the drone carrying the plate support 4 reaches its destination, it slowly lowers its altitude, allowing the lowest plate support 4 to be placed stably on the ground. As the descent continues, the quick-release lever 6 moves downwards and further inserts into the quick-release seat 5. The upper truncated cone 63 contacts the inclined surface of the locking block 55 and generates a squeezing force, pushing the locking pins 53 on both sides to slide outwards along the insertion hole 52 until the locking block 55 passes through the upper truncated cone 63. Under the elastic force of the return spring 56, the locking block 55 resets and locks onto the conical surface of the upper truncated cone 63. At this point, the drone ascends, and the locking block 55 presses the upper truncated cone 63 downwards until it comes into contact with it. After the two are in contact, they form a continuous end. The locking block 55 continues to move along the conical surface of the upper truncated cone 63, further compressing the locking block 55, and passes through the continuous end face of the two to reach the bottom of the lower truncated cone, thus completing the unlocking. No manual assistance is required for assembly and disassembly throughout the process, improving operational portability.

[0050] In one specific implementation, see Figure 4 and Figure 5 The top surface of the plate support 4 is provided with a plate groove 17. After the quick release rod 6 is inserted into the quick release seat 5, the limiting block 54 at one end of the locking pin 53 extends to the top of the plate groove 17.

[0051] By creating a mounting groove 17 on the top surface of the mounting bracket 4 that matches the contour of the photovoltaic panel, the photovoltaic panel can be stably placed in the mounting bracket 4. In the quick-release structure, after the connecting frame 3 and the mounting bracket 4 are connected, the quick-release rod 6 is inserted into the quick-release seat 5, and the locking block 55 is inserted into the gap between the upper frustum 63 and the lower frustum 64. At this time, the locking block 55 abuts against the surface of the pin 62, and the locking pin 53 extends outward so that the limiting block 54 at its end extends to the upper area of ​​the mounting groove 17, thereby abutting the photovoltaic panel in the mounting groove 17, improving the stability of the photovoltaic panel, and preventing the photovoltaic panel from being dislodged from the mounting bracket due to force majeure vibration. In addition, the surface of the limiting block 54 can be covered with rubber material to prevent scratches and damage to the surface of the photovoltaic panel, ensuring the appearance and functional integrity of the photovoltaic panel.

[0052] In one specific implementation, see Figure 2 The reciprocating lifting mechanism includes two symmetrically arranged spare plate conveyor belts 7 in the spare plate box 1. Each spare plate conveyor belt 7 includes multiple vertically spaced rotating rollers 71 and a chain belt 72 wound around the rotating rollers 71. The carrying unit is connected to the chain belt 72. The drive component is in transmission cooperation with both spare plate conveyor belts 7 and drives the spare plate conveyor belts 7 to move upward synchronously.

[0053] The spare plate conveyor belt 7 uses a combination of rotating rollers 71 and chain belt 72 for transmission, which has strong load-bearing capacity and high transmission efficiency. Through the carrying unit, the chain belt 72 can stably support multiple sets of plate support brackets 4. Under the action of the drive component, the plate support brackets 4 can be smoothly transported to the opening on the top surface of the spare plate box 1 for docking by the UAV. After the conveying is completed, the carrying unit continues to move in a cycle with the chain belt 72, moving downwards along the other side of the spare plate conveyor belt 7 and returning to the loading position at the bottom of the spare plate box 1, realizing reciprocating cycle.

[0054] In one specific implementation, see Figure 2 The bearing unit includes two support plates 8, which are respectively set on the two side chain belts 72 and are perpendicularly connected to the chain belts 72. The two ends of the plate holder 4 are respectively placed on the support plates 8 on the same plane of the two spare plate conveyor belts 7.

[0055] The load-bearing unit uses two support plates 8, which are vertically fixed to the chain belts 72 on both sides and are on the same plane, synchronously supporting the plate bracket 4. The structure is simple and highly practical.

[0056] In one specific implementation, see Figure 2 and Figure 3The drive assembly includes a drive motor 9, a drive wheel 10, a first driven wheel 11, a second driven wheel 12, a drive gear 13, and a reversing shaft 14. The drive wheel 10 and the drive gear 13 are coaxially fixedly mounted on the output shaft of the drive motor 9. The first driven wheel 11 and the second driven wheel 12 are respectively fixedly mounted on the rotating shafts of the two rotating rollers 71. The drive wheel 10 is connected to the first driven wheel 11 via a first transmission belt 22. The reversing shaft 14 is rotatably mounted on the spare plate box 1. A reversing gear 15 and a reversing wheel 16 are coaxially fixedly mounted on the reversing shaft 14. The reversing gear 15 meshes with the drive gear 13. The reversing wheel 16 is connected to the second driven wheel 12 via a second transmission belt 23.

[0057] The drive assembly is controlled by a single drive motor 9, which drives two spare plate conveyor belts 7 to run synchronously. Specifically, when the drive motor 9 starts, the drive wheel 10 on its output shaft drives the first driven wheel 11 to rotate through the first transmission belt 22, thereby driving the rotating roller 71 on one side to rotate, thus realizing the operation of the spare plate conveyor belt 7; while the drive gear 13 on its output shaft drives the reversing gear 15 on the reversing shaft 14 to rotate, and the reversing shaft 14 rotates synchronously. The reversing wheel 16 on it drives the second driven wheel 12 to rotate through the second transmission belt 23. With the help of the reversing action of gear meshing, the rotation direction of the reversing shaft 14 is opposite to that of the output shaft of the drive motor 9, so that the rotation direction of the second driven wheel 12 is exactly opposite to that of the first driven wheel 11, thereby making the rotating rollers 71 on both sides rotate towards each other, and finally realizing that the transport direction of the two spare plate conveyor belts 7 is consistent, ensuring that the support plates 8 on both side chain belts 72 always remain on the same plane, and synchronously and smoothly conveying the plate support 4 upward.

[0058] In one specific implementation, see Figure 1 and Figure 7 The preparation box 1 is equipped with a disassembly plate 18 at the bottom of the operation window 2.

[0059] By setting the unloading plate 18, the photovoltaic panel mounting bracket 4 recovered by the drone can be unloaded here, and at the same time, it is convenient to place the photovoltaic panel smoothly into the mounting bracket 4.

[0060] In one specific implementation, see Figure 4 , Figure 5 and Figure 6 The bottom of the sleeve 51 is provided with an outer expansion sleeve 19.

[0061] The outer expansion cylinder 19 provides a guide for the insertion of the quick-release lever 6, expands the insertion alignment range of the quick-release lever 6, and ensures simple, convenient and smooth docking and positioning.

[0062] In one specific implementation, see Figure 1 The bottom of the spare plate box 1 is provided with a tracked moving base 20, and the spare plate box 1 is connected to a plate trolley 21 by a rear suspension.

[0063] The tracked mobile base 20 has excellent adaptability to mountainous terrain. When paired with the sheet metal cart 21 to transport photovoltaic panels, the spare sheet box 1 can move toward the work destination, thereby gradually reducing the round-trip distance of the drone and improving work efficiency.

[0064] The present invention also provides an auxiliary hoisting method for mountain photovoltaic installation, based on the auxiliary hoisting device for mountain photovoltaic installation as described above, comprising the following steps:

[0065] S1. Connect the mounting frame 3 to the drone;

[0066] S2. Install the photovoltaic panel into the empty panel mounting bracket 4 and place it into the bearing unit in the spare panel box 1 through the operation window 2.

[0067] S3. The drone hovers above the spare plate box 1, starts the drive motor 9 to drive the spare plate conveyor belt 7 to transport the plate support 4 upward, and docks with the plate support 4 through the connecting frame 3. The drone may dock with the plate support 4 depending on its lifting capacity.

[0068] S4. After docking is completed, the drone flies to the destination and descends in altitude. The quick release lever 6 and quick release seat 5 detach, and the plate holder 4 is quickly placed at the destination. At the same time, the spare plate box 1 moves toward the destination via the tracked moving base 20.

[0069] S5. Connect to the idle board support 4 at the destination and transport it back to the spare board box 1.

[0070] S6, jump to S2, until the day's work is completed.

[0071] This method achieves continuous and efficient transportation of photovoltaic panels through a closed-loop workflow of "pre-batch loading - rapid drone docking - hoisting - rapid unloading - recovery of idle panel support brackets 4," effectively shortening the drone's hovering and waiting time and improving operational efficiency. Simultaneously, the spare panel box 1 has the capacity to store multiple load-bearing units in batches, continuously providing panel docking for multiple drones, forming a collaborative operation mode of "one spare panel box 1 + multiple drones." Furthermore, the panel support brackets 4 can be stacked and docked, adapting to drones with different carrying capacities, allowing for flexible selection of single or multiple stacked panel support brackets 4 for hoisting, avoiding wasted transport capacity. In addition, in step S4, after docking is completed, the drone hoisting operation and the movement of the spare panel box 1 proceed synchronously, gradually shortening the drone's round-trip flight distance, reducing drone energy consumption and battery replacement frequency, and improving operational efficiency. This method effectively overcomes the "last mile" transportation bottleneck in mountainous photovoltaic installations, offering operational deployment flexibility and transportation efficiency far exceeding traditional methods, and is particularly suitable for construction needs in complex terrains such as mountains and hills.

[0072] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention.
