Description

Technical Field

[0001] The invention relates to the technical field of agricultural unmanned aerial vehicles, in particular to a low-flying, suspended, anti-collision agricultural unmanned aerial vehicle. Background Art

[0002] A drone is an unmanned aircraft that can be controlled by electronic devices. It can greatly improve work efficiency in agriculture, and drones can complete tasks that cannot be completed by humans. However, existing drones still have certain usage defects during use. Due to the large survey range and too many uncontrollable factors in ground control, drones do not have anti-collision functions. Once a collision occurs, the drone may even be directly damaged in severe cases, causing economic losses to users.

[0003] An agricultural survey anti-collision UAV with announcement number CN209634722U can effectively protect the UAV during landing or flight to prevent damage caused by collision. At the same time, it solves the problem that current survey UAVs have too many uncontrollable factors in ground control due to their large survey range, and the UAVs do not have anti-collision functions. Once a collision occurs, serious cases may even directly damage the body. Through the setting of the friction pad, when the UAV lands, the friction pad first contacts the ground. The wear resistance coefficient of the friction pad is very high, avoiding anti-slip treatment. The friction pad can protect the anti-collision plate and improve the anti-collision performance of the UAV.

[0004] In the above-mentioned public patent technology, the above-mentioned problems are solved by a drone, but the following defects still exist: the anti-collision structure is arranged at the lower end of the rotor support plate and the rotating fan blades. The drone is protected by arranging an anti-collision structure at the lower end of the landing gear, resulting in the upper end of the drone being directly exposed. During the take-off of the drone, the rotating fan blades directly drive the overall body to rise and fall. During the movement, it is difficult to judge the dangerous situation that occurs, which can easily cause a collision at the upper end of the drone and damage to the rotating fan blades of the drone, resulting in poor anti-collision effect of the drone.

[0005] In response to the above problems, it is urgently necessary to carry out innovative designs based on the original UAV structure. Summary of the invention

[0006] The purpose of the present invention is to provide a low-flying, suspended, anti-collision agricultural drone to solve the problem proposed in the above-mentioned background technology that the upper end of the drone is directly exposed, and the rotating fan blades directly drive the overall body to rise and fall during the take-off of the drone. It is difficult to judge the dangerous situation that occurs during the movement, which can easily cause the upper end of the drone to collide, and the rotating fan blades of the drone to be damaged, resulting in poor anti-collision effect of the drone.

[0011] Preferably, the buffer structure comprises an adjusting rod, and the lower end of the supporting rod is rotatably mounted on the adjusting rod, and the lower end of the adjusting rod is fixedly mounted with a contact rod.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0026] In a specific embodiment, Figure 1-Figure 2 As shown, the basic use process of the drone is disclosed; a body 1 and a propeller mechanism 2 arranged on the outside of the body 1; a charging frame 3 is arranged inside the body 1, and a mounting plate 4 is fixedly installed at the lower end of the body 1, and a hook 5 is fixedly installed at the lower end of the mounting plate 4, a fixing rod 6 is fixedly installed at the lower end of the body 1, and a supporting rod 7 is fixedly installed at the lower end of the fixing rod 6.

[0027] When using the low-flying, suspended, anti-collision agricultural drone, the object to be transported is wrapped and hung on the lower end of the hook 5. After completing the above operations, the drone can be controlled to take off through electronic equipment. During the take-off of the drone, the object will be moved by the hook 5, and the drone can be moved to the required position through manual operation. In addition, during the operation of the drone, the anti-collision ring 16 and the anti-collision arc rod 17 on the outside will wrap the drone, which can reduce the damage caused by the drone in the event of an accidental collision. The anti-collision ring 16 and the anti-collision arc rod 17 are hollow structures inside, which can reduce the load-bearing burden of the drone and ensure the normal operation of the drone.

[0028] In one specific embodiment, Figure 1-Figure 5 As shown, the working process of the anti-collision structure of the unmanned aerial vehicle is disclosed; an anti-collision structure for protecting the body 1 is arranged on the outer side of the upper end of the body 1; the anti-collision structure comprises a fixed block 8 and a support plate 9, the fixed block 8 is fixedly mounted on the outer side of the body 1, and the support plate 9 is slidably mounted inside the fixed block 8, and an air outlet 11 is provided at one end of the fixed block 8 away from the body 1, and an air outlet groove 12 is provided at one end of the fixed block 8 away from the body 1, and the air outlet groove 12 is located at the upper end of the air outlet 11; a support spring 10 is fixedly mounted on one end of the support plate 9 close to the fixed block 8, and the support spring 10 is located inside the fixed block 8, and a fixed cylinder 13 is fixedly mounted on one end of the support plate 9 away from the body 1; a positioning rod 15 is slidably mounted on one end of the fixed cylinder 13 away from the support plate 9, and a reset spring 14 is fixedly mounted on one end of the positioning rod 15 close to the fixed cylinder 13, an anti-collision ring 16 is fixedly mounted on one end of the positioning rod 15 away from the support plate 9, and an anti-collision arc rod 17 is fixedly mounted on the upper end of the anti-collision ring 16.

[0029] When using the low-flying, suspended, anti-collision agricultural drone, the anti-collision ring 16 and the anti-collision arc rod 17 need to be wrapped around the outside of the drone. When a collision occurs during the upward movement of the drone, the anti-collision arc rod 17 will contact the object and prevent the body 1 from being collided. During this process, the support plate 9 will slide downward inside the fixed block 8, and the downward movement of the support plate 9 will squeeze the support spring 10 and cause the support spring 10 to contract. During the downward movement of the support plate 9, the gas inside the fixed block 8 will be discharged outward through the air outlet groove 12 and the air outlet hole 11, thereby slowing down the downward movement speed of the support plate 9 and achieving the effect of slowing down the impact of vibration on the body 1; and during the continued downward movement of the support plate 9, the lower end surface of the support plate 9 will move to the lower end of the air outlet groove 12. At this time, the gas inside the fixed block 8 will be discharged through the air outlet hole 11. The air is discharged through the air hole 11, thereby slowing down the exhaust speed of the gas inside the fixed block 8, achieving the effect of slowing down the downward movement of the support plate 9 again, and then reducing the impact of the vibration on the body 1 again, thereby improving the anti-collision effect of the UAV; and when the UAV is collided in horizontal movement, the anti-collision ring 16 and the positioning rod 15 near the anti-collision arc rod 17 that are collided will move, and the positioning rod 15 will move toward the inside of the fixed tube 13 during the movement of the positioning rod 15 and squeeze the reset spring 14, and the reset spring 14 will shrink and slow down the movement of the positioning rod 15 after being squeezed, thereby achieving the effect of horizontal collision shock absorption; and the anti-collision ring 16 and the anti-collision arc rod 17 are made of hollow aluminum alloy, which will deform and protect the body 1 when subjected to a large impact, thereby improving the overall anti-collision effect of the UAV.

[0030] Based on the above embodiments, Figure 1-Figure 2 and Figure 6-Figure 7 As shown, the working process of the buffer structure of the drone is disclosed; a buffer structure for protecting the body 1 is provided at the lower end of the body 1; the buffer structure includes an adjusting rod 18, and the adjusting rod 18 is rotatably mounted with the lower end of the support rod 7, and the lower end of the adjusting rod 18 is fixedly mounted with a contact rod 19; the upper end of the contact rod 19 is rotatably mounted with a rotating rod 20, and the upper end of the rotating rod 20 is rotatably mounted with a sliding member 21, and the sliding member 21 is slidably connected to the fixed rod 6; a docking rod 22 is rotatably mounted on the outer side of the adjusting rod 18, and a moving cylinder 23 is slidably mounted on the outer sides of the two groups of docking rods 22, and a strong spring 24 is provided inside the moving cylinder 23, and both ends of the strong spring 24 are fixedly connected to the two groups of docking rods 22.

[0031] When using the low-flying suspension anti-collision agricultural drone, the drone may land quickly, and the existing agricultural drones are generally large in size and prone to damage. During this process, the contact rod 19 will first contact the ground during the descent of the body 1. At this time, the contact rod 19 will deflect after contacting the ground and drive the adjustment rod 18 to move synchronously. At this time, the distance between the two groups of contact rods 19 will increase, and the two groups of similar docking rods 22 will also move away and move, and the docking rod 22 will move inside the moving cylinder 23 and stretch the strong spring 24. The strong spring 24 will reversely prevent the two groups of docking rods 22 from moving away, thereby reducing the impact force between the drone and the ground, and the adjustment rod 18 will drive the rotating rod 20 to rotate during the rotation of the rotating rod 20. The rotation of the rotating rod 20 will push the sliding member 21 to move upward. The upward movement of the sliding member 21 will make it contact with the mounting plate 4, thereby preventing the rotating rod 20 from continuing to rotate, thereby achieving the effect of controlling the contact rod 19 to continue to rotate, thereby protecting the drone and increasing the overall practicality.
