Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a hoisting and fixing frame for UAVs used in mountain photovoltaic construction. Background Technology

[0002] A drone is an unmanned aircraft controlled by radio remote control equipment and its own program control device.

[0003] Drones have a wide range of applications, including military and civilian use. When installing photovoltaics on mountains, the harsh mountain environment makes it difficult to transport photovoltaic components with large machines. Therefore, drones are needed for transportation. The usual method is to attach lifting ropes to a hoisting frame and then lift and transport the photovoltaic components. However, due to the drone's flight inertia and the wind, the lifting ropes may swing, which poses a certain danger to the drone's flight. In severe cases, the drone may fall, causing economic losses.

[0004] Therefore, we provide a hoisting and fixing frame for drones used in mountain photovoltaic construction. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned technical problems by providing a hoisting and fixing frame for drones used in mountain photovoltaic construction, thereby reducing the amplitude of swaying.

[0006] In view of this, the present invention provides a hoisting and fixing frame for a mountain photovoltaic construction drone, including a fixing frame, a balance bar connected to opposite sides of the fixing frame, a rotating rod connected to the lower end of the balance bar, a buffer rod connected to the lower end of the rotating rod, and a sliding block connected to the inner wall of the buffer rod.

[0007] Preferably, both ends of the balance bar are fixedly connected to the opposite sides of the fixed frame, the upper and lower ends of the rotating rod are rotatably connected to the lower end of the balance bar and the upper end of the buffer rod, respectively, and the sliding block slides on the inner wall of the buffer rod via a sliding shaft.

[0008] Preferably, springs are fixedly connected to both sides of the sliding block, and the end of the spring away from the sliding block is fixedly connected to the inner wall of the buffer rod. A push rod is fixedly installed at the lower end of the sliding block and is symmetrically distributed.

[0009] Preferably, both ends of the buffer rod are slidably connected to the inner wall of the fixed frame via sliding shafts, and a limit plate is fixedly installed at the upper end of the buffer rod.

[0010] Preferably, telescopic devices are fixedly installed on both sides of the lower half of the rotating rod, and the end of the telescopic device away from the rotating rod is fixedly connected to the lower end of the balance rod. The rotating rod can be set as a column or a regular polygon, and the number of rotating rods is not limited.

[0011] Preferably, the lower end of the fixed frame is rotatably connected to a balance wing, and the specifications and form of the balance wing are not limited.

[0012] Preferably, one end of the push rod extends to the outside of the buffer rod, and one end of the balance wing is located within the movement range of the push rod.

[0013] Compared with the prior art, this utility model provides a hoisting and fixing frame for drones used in mountain photovoltaic construction, which has the following beneficial effects:

[0014] 1. This utility model, by setting a buffer rod, can support the photovoltaic workpiece being hoisted, and at the same time can swing relative to the balance rod, ensuring that the balance rod remains stable while the buffer rod swings. At the same time, the swing of the buffer rod can cancel out the swing of the photovoltaic workpiece, reducing its swing amplitude, thereby achieving the effect of reducing the swing amplitude.

[0015] 2. This utility model, by setting a balance bar, can strengthen the structure of the drone hoisting and fixing frame, and at the same time, can maintain stability by rotating the bar when the buffer bar swings. Thus, when the photovoltaic workpiece swings, the drone body can maintain a certain balance, thereby achieving the effect of reducing the swing amplitude and improving the ability to maintain flight stability and balance.

[0016] 3. This utility model, by setting a balancing wing, and the folding angle of the balancing wing is the same as the unfolding angle of the fixed frame support leg, can reduce the wind resistance of the folding wing during flight. At the same time, when the balancing wing is unfolded, according to its principle, it can keep the tilted drone body balanced, and can have a buffering effect on the sway, thereby further reducing the sway amplitude.

[0017] 4. By setting a rotating rod, this utility model can maintain rotation when the buffer rod slides, thus preventing the buffer rod from swinging and causing the balance rod or fixed frame to shake, thereby achieving the effect of reducing the swing amplitude.

[0018] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] Example: A hoisting and fixing frame for a mountain photovoltaic construction drone, such as... Figures 1-4 As shown, it includes a fixed frame 1, with balance bars 3 connected to opposite sides of the fixed frame 1, a rotating rod 9 connected to the lower end of the balance bar 3, a buffer rod 2 connected to the lower end of the rotating rod 9, and a sliding block 7 connected to the inner wall of the buffer rod 2.

[0027] The sliding block 7 has a fixed ring installed at its lower end. The photovoltaic construction workpiece is fixed to the fixed ring with a rope. When the drone takes off to transport the photovoltaic workpiece, if a swinging phenomenon occurs during the transport, the rope swings first, pulling the fixed ring. The sliding block 7 is then pulled by the rope. Through the swinging of the rope, the rope transmits the swinging force to the sliding block 7. At this time, the swinging force is insufficient to compress the springs on both sides of the sliding block 7. The swinging force, transmitted through the sliding block 7, can pull the buffer rod 2 in the direction of the photovoltaic workpiece's swing. While the buffer rod 2 is sliding, it pulls the rotating rod 9 to one side, and the telescopic device 10 performs a telescopic action. At the same time, since the balance rod 3 is fixed on the fixed frame 1, the balance rod 3 can maintain balance, and the rotating rod 9 rotates at its lower end. At this time, the buffer rod 2, which is sliding in the direction of the photovoltaic workpiece's swing, can cancel out the swinging force of the photovoltaic workpiece and the rope through instantaneous sliding. At the same time, when the photovoltaic workpiece is about to swing in the opposite direction, the buffer rod 2 can be restored under the pull of the telescopic device 10. Upon returning to its initial position, the buffer rod 2 can further counteract the force of its reverse swing during its return to the initial position. This alleviates minor swaying during the transport of photovoltaic workpieces by the drone, reducing the sway amplitude and ensuring the safety of the drone's operation. When the photovoltaic workpiece sways significantly, the buffer rod 2 stops sliding when it reaches the limit plate. Simultaneously, the sliding block 7 continues to be subjected to the swaying tension, which is greater than the extension force of the springs on both sides. The springs then extend and retract, causing the sliding block 7 to slide rapidly in the swaying direction. This sliding motion partially counteracts the sway amplitude of the photovoltaic workpiece, reducing its amplitude. Since the counteracted sway tension is less than the spring support force, the sliding block 7 returns to its initial position. The buffer rod 2 then repeats its sliding motion, further reducing the sway amplitude of the photovoltaic workpiece, thus achieving the desired effect of minimizing the sway.

[0028] like Figures 1-4 As shown, both ends of the balance bar 3 are fixedly connected to the opposite sides of the fixed frame 1. The upper and lower ends of the rotating rod 9 are rotatably connected to the lower end of the balance bar 3 and the upper end of the buffer rod 2, respectively. The sliding block 7 slides on the inner wall of the buffer rod 2 through the sliding shaft.

[0029] Springs 8 are fixedly connected to both sides of the sliding block 7. The end of the spring 8 away from the sliding block 7 is fixedly connected to the inner wall of the buffer rod 2. Push rods 6 are fixedly installed at the lower end of the sliding block 7 and are symmetrically distributed.

[0030] Both ends of the buffer rod 2 are slidably connected to the inner wall of the fixed frame 1 via sliding shafts, and a limit plate is fixedly installed on the upper end of the buffer rod 2.

[0031] The lower half of the rotating rod 9 is fixedly installed with expansion joints 10 on both sides. The end of the expansion joint 10 away from the rotating rod 9 is fixedly connected to the lower end of the balance bar 3. The rotating rod 9 can be set as a column or a regular polygon, and the number of rotating rods 9 is not limited.

[0032] The rotating rod 9 is designed as a column and a regular polygon, which can reduce wind resistance during the flight of the drone, and the rotating rod 9 can swing relative to the balance rod 3 and the buffer rod 2.

[0033] When the photovoltaic workpiece swings with the rope, the swing force is less than the extension force of the spring 8. At this time, the sliding block 7 pulls the buffer rod 2 to slide. The sliding of the buffer rod 2 pulls the rotating rod 9. At the same time, the telescopic device 10 performs an extension and retraction action. The buffer rod 2 and the balance rod 3 are misaligned. Since the photovoltaic workpiece needs to swing to one side, the downward pulling force is required to make the sliding block 7 pull the buffer rod 2 to slide to the swinging side. The stationary buffer rod 2 has a momentary sliding action to one side. At this moment, the momentary sliding action can buffer and cancel the swing force of the photovoltaic workpiece that is swinging. At this time, part of the swing force of the photovoltaic workpiece is canceled. By canceling it multiple times, the swing amplitude of the photovoltaic workpiece can be reduced. At the same time, when the swing amplitude is large, the buffer rod 2 slides to the maximum distance. At this time, the spring 8 is squeezed by the sliding block 7, and the other spring 8 is stretched. The sliding block 7 slides on the inner wall of the buffer rod 2. At the same time, the sliding block 7 drives the push rod 6 to move on the outside of the buffer rod 2.

[0034] like Figures 1-4 As shown, a balance wing 5 is rotatably connected to the lower end of the fixed frame 1. The specifications and style of the balance wing 5 are not limited.

[0035] One end of the push rod 6 extends to the outside of the buffer rod 2, and one end of the balance wing 5 is within the range of movement of the push rod 6.

[0036] The lifting principle of the stabilizer wing 5 is based on Bernoulli's principle, which states that an increase in the velocity of a fluid (in this case, air) leads to a decrease in pressure. Therefore, because the air velocity on the upper surface of the stabilizer wing 5 is faster and the pressure is relatively lower, while the air velocity on the lower surface is slower and the pressure is relatively higher, this pressure difference creates upward lift. This principle is existing technology, and the lift generated is related to the shape and material of the stabilizer wing 5, which are not limited here. The stowage angle of the stabilizer wing 5 is the same as the deployment angle of the fixed frame support legs. During flight, the stowed stabilizer wing 5 can reduce wind resistance. The shape of one end of the stabilizer wing 5 is not limited, as long as it can engage with one end of the push rod 6.

[0037] Driven by the sliding block 7, the push rod 6 moves in the swing direction. The greater the swing amplitude, the farther the sliding block 7 moves. Since the components and the swing force are concentrated on one side, the drone will tilt. The push rod 6 continues to move and engages with one end of the stabilizer wing 5. The push rod 6 pushes and unfolds the stabilizer wing 5. At this time, one side of the drone begins to rise, which can correct the tilted fuselage and buffer the swing, further reducing the swing amplitude.

[0038] Working principle: When the photovoltaic workpiece swings, the sliding block 7 pulls the buffer rod 2 to slide. When the buffer rod 2 slides to the maximum distance, the sliding block 7 starts to move, and at the same time the push rod 6 starts to move. At this time, the balance wing 5 unfolds.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
