Description

Technical Field

[0001] The present invention relates to the field of photovoltaic transportation technology, and in particular to a photovoltaic material lifting device suitable for unmanned aerial vehicle (UAV) transportation in mountainous areas. Background Art

[0002] Photovoltaic power generation, as a clean energy alternative to traditional energy, has become an important means to promote energy reform and respond to climate change under the background of national advocacy and encouragement of construction.

[0003] The sunny side of the mountain is rich in solar energy and is one of the main sites for photovoltaic power generation construction. However, the mountain is steep and cars cannot go up it. Oxen and horses are inefficient and difficult to control. Manual transportation has great safety risks. The slightest carelessness may cause hidden cracks and damage to photovoltaic modules. The "last mile" transportation from the road at the foot of the mountain to the photovoltaic module installation site has become a major safety hazard and quality control difficulty in project construction.

[0004] Drones have the advantages of large payload, flexible use, small terrain restrictions, and automatic obstacle avoidance, and are widely used in the "last mile" transportation of photovoltaic materials. When drones transport photovoltaic materials, especially photovoltaic panels, the panels need to be hung under the drone. Currently, drones mostly use cross-arranged cables to fix the panels, and the cables need to be manually bound and unbound. First, the time for binding and unbinding the cables is long, which greatly reduces the efficiency of photovoltaic material transportation. Secondly, the drone needs to hover in the air during the binding and unbinding process, which invisibly consumes the drone's power, greatly reducing the number of drone operations, increasing the frequency of drone battery replacement, and further reducing the efficiency of photovoltaic material transportation. In addition, this binding method is extremely challenging for the binding technique, and the photovoltaic panels can easily slide with the cables, causing the photovoltaic panels to tilt or even fall, which can easily cause damage to the photovoltaic panels. Summary of the Invention

[0005] The technical solution of the present invention is to provide a photovoltaic material lifting device suitable for drone transportation in mountainous areas. This device realizes automatic clamping and release of photovoltaic panels through the linkage of a lever, a slider, a synchronizer and a clamping rod, which significantly improves transportation efficiency, reduces energy consumption and ensures construction progress. Combined with the advantages of drones, it can efficiently solve the problem of photovoltaic transportation in mountainous areas and provide strong support for energy reform and the "dual carbon" goals.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a photovoltaic material lifting device suitable for UAV transportation in mountainous areas, comprising a frame, with support frames installed at both ends of the frame;

[0007] Sliders are elastically slidably arranged at both ends of the frame through elastic members;

[0008] Clamping rods: A group of clamping rods is set at both ends of the frame, and each group of clamping rods has at least two, and are rotatably set on both sides of the frame; each clamping rod has an inclined slot;

[0009] The synchronizer is fixed on both sides of the slider, and a synchronizer shaft is fixed on the end thereof. The synchronizer shaft is slidably arranged in the inclined slot and drives the clamping rod to rotate through the inclined slot;

[0010] The shifting rod is rotatably arranged at both ends of the frame. When lifting, the shifting rod drives the slider and the synchronizer to move relative to the frame. The synchronizer drives the two clamping rods in the same group to rotate synchronously in opposite directions through the inclined slot.

[0011] The locking part is arranged between the slider and the frame. During the loading process, when the slider moves to the lowest point relative to the frame, the locking part limits the slider from resetting. During the unloading process, after the photovoltaic panel falls to the ground, the locking part releases the limit on the slider, allowing the slider to slide relative to the frame, thereby allowing the two clamping rods in the same group to unfold.

[0012] As a further solution of the present invention, the locking member includes:

[0013] A spring plate is located between the slider and the frame, with the fixed end of the spring plate fixed to the slider and the free end of the spring plate fixed with a guide shaft;

[0014] The guide member is located between the spring plate and the frame and is fixed to the frame; a groove is formed on the side wall of the guide member;

[0015] The guide block is fixed in the guide member and slides with the guide shaft; both sides of the guide block are inclined, and a locking groove is provided at the bottom of the guide block;

[0016] The protrusion is fixed in the groove and located below the locking groove.

[0017] As a further solution of the present invention, each side wall of the clamping rod is provided with a group of side clamps for clamping the side edges of the photovoltaic panel, and a synchronization structure is provided between each group of side clamps and the lever on the same side; when the lever rotates, the synchronization structure controls the side clamps to clamp or release the photovoltaic panel.

[0018] As a further solution of the present invention, each group of side clamps are arranged in a linear array along the length direction of the clamping rod, and a connecting rod is fixed between the side clamps in each group. The synchronization structure includes:

[0019] The guide rods are arranged in a linear array, fixed to the side walls of the clamping rods, and slidably arranged with the side clamps;

[0020] a return spring, disposed between the guide rod and the side clamp;

[0021] The traction rope has two ends respectively arranged between the connecting rod and the shifting rod.

[0022] As a further solution of the present invention, a transverse groove is provided on the top of the slider; and the shifting rod comprises:

[0023] The driving part is rotatably mounted on the frame through a bracket; the top of the driving part is connected to the traction rope;

[0024] The driven part is rotatably mounted on the driving part and is connected to the driving part via a torsion spring;

[0025] The driving shaft is fixed to the free end of the driven part and is slidably arranged with the transverse groove.

[0026] As a further solution of the present invention, the frame includes a pair of sliding sleeves, which are slidably matched with the sliders, and a sliding rod is provided between the paired sliding sleeves for common sliding. Limiting plates are provided at both ends of the sliding rod. A screw is fixed on each of the sliding sleeves, and the two screws are threadedly connected to a screw sleeve.

[0027] As a further solution of the present invention, reinforcing ribs are provided between each group of the clamping rods, and the clamping rods include an inclined section and a vertical section. The inclined groove is opened on the inclined section, and a lifting part fixed to the reinforcing rib is provided at the bottom of the vertical section.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] This device automatically clamps and releases photovoltaic panels through the coordination of a lever, slider, synchronizer, and clamping rod. When lowering to load the panels, the lever rotates, causing the slider to descend and drive the two clamping rods in the same group to form a frame, automatically loading the panels. When unloading the panels, the drone takes off, rotating the lever, releasing the clamping rods from the frame and automatically releasing the panels. This entire process eliminates the need for frequent manual cable manipulation, significantly shortening transportation time and reducing drone power consumption during hovering. This significantly improves the efficiency of transporting photovoltaic materials and effectively ensures project construction progress. Drones, with their advantages of high payload capacity, flexible operation, limited terrain restrictions, and automatic obstacle avoidance, combined with the device's automatic clamping and release capabilities, can easily navigate challenging terrain, such as steep terrain impassable by cars and the inefficient and difficult-to-control conditions of cattle and horses. This provides an efficient, safe, and convenient transportation solution for photovoltaic power generation projects in mountainous areas, significantly promoting energy reform and the achievement of the "dual carbon" strategic goals.

[0045] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0046] See also Figures 1-12 The present invention provides a technical solution: a photovoltaic material lifting device suitable for UAV mountain transportation, comprising a frame 1, on which a support frame 15 is provided:

[0047] The slider 2 is elastically slidably arranged at both ends of the frame 1 through the elastic member 22; the elastic member 22 plays the role of storing and releasing elastic force during the movement of the slider 2; in this embodiment, the elastic member 22 is a spring;

[0048] Clamping rods 3: A set of clamping rods 3 is provided at both ends of the frame 1. Each set of clamping rods 3 has at least two clamping rods 3, which are rotatably provided on both sides of the frame 1. Each clamping rod 3 is provided with an inclined slot 35, so that the clamping rod 3 can rotate according to the movement of the slider 2, thereby achieving clamping and releasing actions.

[0049] The synchronizer 4 is fixed on both sides of the slider 2, and a synchronizer shaft 41 is fixed on the end. The synchronizer shaft 41 is slidably set in the inclined groove 35. When the slider 2 moves, the synchronizer 4 will move accordingly and slide in the inclined groove 35 through the synchronizer shaft 41, driving the two clamping rods 3 in the same group to rotate synchronously in opposite directions;

[0050] The lever 5 is rotatably arranged at both ends of the frame 1. When lifting, the lever 5 drives the slider 2 and the synchronizer 4 to move relative to the frame 1, thereby realizing the rotation and clamping action of the clamping rod 3;

[0051] The locking member 6 is provided between the slider 2 and the frame 1. During the loading process, when the slider 2 moves to the lowest point relative to the frame 1, the locking member 6 restricts the slider 2 from resetting. During the unloading process, after the photovoltaic panel falls to the ground, the locking member 6 releases the limit on the slider 2, allowing the slider 2 to slide relative to the frame 1, thereby allowing the two clamping rods 3 in the same group to unfold.

[0052] Lifting preparation stage

[0053] The lever 5 is installed on the drone via a rope, and the drone lifts the lifting device via the lever 5. When the device is suspended in the air, the lever 5 rotates around the hinge point with the frame 1 under the action of the gravity of the lifting device, causing the slider 2 to drive the synchronizer 4 to move upward relative to the frame 1. At the same time, the elastic member 22 accumulates force until the distance between the top of the slider 2 and the frame 1 reaches the maximum. At this time, the bottom spacing of the two clamping rods 3 in the same group rotates to the maximum, forming an "eight" shape, preparing for the subsequent loading of photovoltaic panels.

[0054] Photovoltaic panel loading stage

[0055] When the drone flies to the lifting point of the photovoltaic panel, the drone is controlled to descend vertically from just above the photovoltaic panel; as the drone descends, the support frame 15 gradually contacts the photovoltaic panel, and the frame body 1 stops descending due to the support of the support frame 15. As the drone continues to fall, the force pulling the lever 5 gradually decreases, and the elastic force accumulated in the elastic member 22 is gradually released, causing the slider 2 to move downward relative to the frame body 1, and the slider 2 drives the synchronous member 4 to descend. The synchronous member 4 drives the two clamping rods 3 in the same group to approach each other through the inclined groove 35 that slides with the synchronous shaft 41, and finally the bottom of the clamping rod 3 rotates to the bottom of the photovoltaic panel, and the clamping rods 3 in the same group form a U-shaped frame; then, the drone rises vertically. At this time, the locking member 6 limits the slider 2, so that the slider 2 and the frame body 1 are relatively fixed, and the bottom of the frame gradually contacts the photovoltaic panel and lifts the photovoltaic panel, thereby ensuring that the two clamping rods 3 in the same group maintain the frame state, ensuring that the photovoltaic panel will not fall during transportation;

[0056] The weight of the photovoltaic panel is applied to the frame 1 through the frame, so that the lever 5 is pulled upward by the drone and pulled downward by the frame 1 at the same time. Figure 3 The lever 5 is V-shaped and tilted. The drone pulls the top of the lever 5, and the frame 1 pulls down the hinge point of the lever 5, so that the rotational torque of the lever 5 increases after the photovoltaic panel is lifted, and the two clamping rods 3 in the same group maintain the frame shape. The heavier the photovoltaic panel, the greater the rotational torque of the lever 5, which increases the resistance of the clamping rods 3 to move away from each other, effectively avoiding the problem of increased shaking amplitude due to the increase in the weight of the photovoltaic panel, resulting in increased gaps between the clamping rods 3 in the same group and slipping;

[0057] It should be noted that the photovoltaic panel has a metal frame, and when the clamping rod 3 maintains the frame shape, it only contacts the metal frame of the photovoltaic panel and will not cause damage to the electronic components of the photovoltaic panel;

[0058] Unloading stage

[0059] When the drone transports the photovoltaic panel to the unloading point, the drone descends vertically, and the photovoltaic panel contacts the unloading platform. The drone continues to descend, so that the support frame 15 contacts the top of the photovoltaic panel again, and the locking member 6 releases the limit on the slider 2; then the drone takes off from the unloading point, and the lever 5 rotates under the traction of the drone, so that the slider 2 and the synchronizer 4 rise relative to the frame 1, and the elastic member 22 accumulates force. At the same time, the synchronizer 4 drives the two clamping rods 3 in the same group away from each other through the synchronization shaft 41 and the inclined groove 35, so that the gap between the bottoms of the two clamping rods 3 in the same group is greater than the thickness of the photovoltaic panel, and the two clamping rods 3 in the same group are separated from the photovoltaic panel as the drone rises vertically, realizing automatic unloading of the photovoltaic panel;

[0060] This device automatically clamps and releases photovoltaic panels through the coordination of a lever 5, a slider 2, a synchronizer 4, and a clamping rod 3. During loading, the lever 5 rotates, lowering the slider 2 and driving the two clamping rods 3 in the same group to form a frame, automatically loading the photovoltaic panels. During unloading, the drone takes off, rotating the lever 5, releasing the clamping rods 3 from the frame, and automatically releasing the panels. This entire process eliminates the need for frequent manual manipulation of cables, significantly shortening transportation time and reducing drone power consumption during hovering. This significantly improves the efficiency of transporting photovoltaic materials and effectively ensures project construction progress. Drones, with their advantages of high payload capacity, flexible operation, limited terrain restrictions, and automatic obstacle avoidance, combined with the device's automatic clamping and release functions, can easily navigate challenging terrain, such as steep terrain impassable by cars and the inefficient and difficult-to-control conditions of cattle and horses. This provides an efficient, safe, and convenient transportation solution for photovoltaic power generation projects in mountainous areas, significantly promoting energy reform and the achievement of the "dual carbon" strategic goals.

[0061] The force to maintain the frame shape of the clamping rod 3 is proportional to the weight of the photovoltaic panel. The heavier the photovoltaic panel, the greater the resistance of the clamping rods 3 moving away from each other, and the stronger the force to maintain the frame shape of the clamping rod 3. This effectively avoids the problem of the photovoltaic panel slipping from the gap of the clamping rod 3 due to the increase in the weight of the photovoltaic panel and the increase in the shaking amplitude, reducing the risk of damage to the photovoltaic panel during transportation, and ensuring the quality of photovoltaic materials and the economic benefits of the project.

[0062] As a further solution of the present invention, the locking member 6 includes:

[0063] The spring plate 61 is located between the slider 2 and the frame 1, and the fixed end of the spring plate 61 is fixed to the slider 2; the free end of the spring plate 61 is fixed with a guide shaft 62;

[0064] The guide member 63 is located between the spring plate 61 and the frame 1 and is fixed to the frame 1; a groove 64 is formed on the side wall of the guide member 63;

[0065] The guide block 65 is fixed in the guide member 63 and is in sliding engagement with the guide shaft 62. Both sides of the guide block 65 are inclined, and a locking groove 66 is provided at the bottom of the guide block 65.

[0066] The protrusion 67 is fixed in the groove 64 and is located below the locking groove 66;

[0067] Specifically, when the drone descends vertically from the lifting point, see Figure 12 , the bottoms of the two clamping rods 3 in the same group are in a distanced state, and the guide shaft 62 is at the top of the groove 64;

[0068] When the support frame 15 contacts the top of the photovoltaic panel, the frame body 1 stops descending, and the lever 5 rotates to cause the slider 2 to descend relative to the frame body 1. During this process, the spring plate 61 descends synchronously with the slider 2 and drives the guide shaft 62 to slide downward along the side wall of the guide block 65. At the same time, the bottom of the spring plate 61 is elastically deformed by the horizontal displacement of the guide shaft 62 and accumulates potential energy.

[0069] When the two clamping rods 3 in the same group form a frame shape, the guide shaft 62 moves to the bottom of the groove 64. At this time, the elastic force of the spring plate 61 drives the guide shaft 62 to separate from the guide block 65 and contact the protrusion 67. When the drone moves upward, the slider 2 rises under the action of the lever 5, and the guide shaft 62 rises slightly and enters the locking groove 66. Since the guide shaft 62 is restricted by the locking groove 66, the guide shaft 62 cannot continue to rise, and the slider 2 cannot rise, thereby achieving mechanical locking of the slider 2.

[0070] When the drone descends vertically from the unloading point, see Figure 11 After the photovoltaic panel contacts the unloading platform, the slider 2 drops slightly, causing the guide shaft 62 to move from the locking groove 66, and the spring plate 61 releases its elastic force and returns to a free state; when the drone takes off, the slider 2 rises, and the guide shaft 62 contacts the guide block 65 again and rises along the guide block 65. At the same time, the spring plate 61 undergoes elastic deformation again and accumulates potential energy; when the guide shaft 62 separates from the guide block 65, the guide shaft 62 returns to its original position when the elastic force of the spring plate 61 is released, thereby automatically releasing the lock on the slider 2;

[0071] As a further embodiment of the present invention, each side wall of the clamping rod 3 is provided with a side clamp 8 for clamping the side edge of the photovoltaic panel, and a synchronization structure 9 is provided between each set of the side clamps 8 and the lever 5 on the same side; when the lever 5 rotates, the synchronization structure 9 controls the side clamps 8 to clamp or release the photovoltaic panel;

[0072] As a further solution of the present invention, each group of side clamps 8 is arranged in a linear array along the length direction of the clamping rod 3, and a connecting rod is fixed between the side clamps 8 in each group. The synchronization structure 9 includes:

[0073] The guide rods 91 are arranged in a linear array, fixed to the side wall of the clamping rod 3, and slidably arranged with the side clamps 8;

[0074] A return spring 92 is provided between the guide rod 91 and the side clamp 8;

[0075] The traction rope 93 has two ends respectively arranged between the connecting rod and the shifting rod 5;

[0076] Specifically, participate Figure 5 and Figure 6 When the UAV takes off, the lever 5 rotates and pulls the side clamp 8 through the traction rope 93, so that the side clamp 8 approaches the side of the photovoltaic panel and compresses the reset spring 92; after the side clamp 8 clamps the photovoltaic panel, the side clamp 8 and the frame jointly restrict the photovoltaic panel, so that the photovoltaic panel can move upward relative to the frame, thereby improving the stability of the photovoltaic panel during hoisting; when the lever 5 rotates in the opposite direction, the reset spring 92 releases the elastic force, so that the side clamp 8 moves away from the photovoltaic panel, increasing the distance between the side clamps 8, making it easier for the side clamp 8 to move with the clamping rod 3, and avoiding friction between the side clamp 8 and the photovoltaic panel;

[0077] As a further solution of the present invention, a transverse groove 21 is provided on the top of the slider 2; the lever 5 includes:

[0078] The driving part 51 is rotatably mounted on the frame 1 through a bracket; the top of the driving part 51 is connected to the traction rope 93;

[0079] The driven portion 52 is rotatably mounted on the driving portion 51 and is connected to the driving portion 51 via a torsion spring;

[0080] The driving shaft 53 is fixed to the free end of the driven portion 52 and is slidably arranged with the transverse groove 21;

[0081] For details, see Figure 6 and Figure 7 When the driving part 51 is pulled by the drone, the driving part 51 rotates, and drives the driven part 52 to rotate synchronously through the torsion spring. The driven part 52 drives the slider 2 to rise relative to the frame 1 through the driving shaft 53 in the transverse groove 21, so that the two clamping rods 3 in the same group are close to each other and form a frame shape. At the same time, the driving part 51 also pulls the side clamp 8 through the traction rope 93 to achieve multi-directional limitation of the photovoltaic panel.

[0082] When the clamping rod 3 is in the frame shape, the driving part 51 can continue to rotate relative to the driven part 52 by compressing the torsion spring, and the traction rope 93 continues to apply a pulling force to the side clamp 8, thereby controlling the side clamp 8 to continue to approach the photovoltaic panel and increase the clamping force of the side clamp 8, thereby improving the end limit capability of the photovoltaic panel. Conversely, the side clamp 8 can first move away from the photovoltaic panel and then move with the clamping rod 3;

[0083] In summary, when the side clamp 8 rotates to the end of the photovoltaic panel, it maintains a certain distance from it and then approaches the photovoltaic panel. Conversely, the side clamp 8 can first move away from the photovoltaic panel and then move with the clamping rod 3, thereby increasing the displacement distance of the side clamp 8. On the one hand, when the side clamp 8 has not moved to the end of the photovoltaic panel, it can maintain a sufficient distance to prevent the side clamp 8 from being unable to clamp the end of the photovoltaic panel. On the other hand, after the side clamp 8 clamps the photovoltaic panel, the clamping force of the side clamp 8 on the photovoltaic panel can be increased, and this clamping force is proportional to the gravity of the photovoltaic panel. The greater the gravity of the photovoltaic panel, the greater the rotational torque of the driving part 51 relative to the driven part 52, and the greater the pulling force of the traction rope 93 on the side clamp 8.

[0084] As a further solution of the present invention, the frame 1 includes a pair of sliding sleeves 11; the sliding sleeves 11 are slidably matched with the sliders 2, and a sliding rod 12 is provided between the paired sliding sleeves 11 for common sliding, and a limiting plate is provided at both ends of the sliding rod 12. A screw 13 is fixed on each of the sliding sleeves 11, and the two screws 13 are commonly threadedly connected with a screw sleeve 14; rotating the screw sleeve 14 drives the sliding sleeve 11 to move in the opposite direction, thereby adjusting the width of the frame 1 to adapt to the lifting requirements of photovoltaic panels of different sizes.

[0085] Specifically, the screw sleeve 14 is rotated to move the screw rods 13 connected at both ends of the screw sleeve 14 closer to or farther away from each other, thereby driving the sliding sleeve 11, the clamping rod 3 and the side clamps 8 thereon to move synchronously, thereby realizing the lifting of photovoltaic panels of different sizes.

[0086] As a further solution of the present invention, reinforcing ribs 34 are provided between each group of the clamping rods 3, and the clamping rods 3 include an inclined section 31 and a vertical section 32. The inclined groove 35 is opened on the inclined section 31, and the bottom of the vertical section 32 is provided with a lifting part 33 fixed to the reinforcing rib 34; specifically, the lifting part 33 can support the bottom of the photovoltaic panel, and the reinforcing rib 34 can strengthen the connection between each group of clamping rods 3, so that each group of clamping rods 3 can move synchronously.
