With their powerful load capacity and flexible flight performance, these UAVs are playing an increasingly important role in logistics, emergency rescue, geographic surveying and mapping, film and television shooting and other fields.

[0003] However, although rotary-wing UAVs have demonstrated extraordinary capabilities and potential in many fields, their load capacity has become a key factor restricting their further development when faced with heavy-load tasks. Traditional rotary-wing UAVs have obvious limitations in improving load capacity and are unable to meet the needs of complex tasks such as high loads and long distances.

[0004] Therefore, in view of the above situation, there is an urgent need to develop a high-load rotor UAV equipped with a helium lift device to overcome the shortcomings in current practical applications. Summary of the invention

[0005] The purpose of the embodiments of the present invention is to provide a high-load rotor UAV equipped with a helium lift device, aiming to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above object, the present invention provides the following technical solutions: A high-load rotor UAV equipped with a helium lift device comprises a rotor UAV, a chassis, a support column, an upper base plate, a rope and a helium balloon, wherein the upper end of the rotor UAV is fixedly connected to the chassis, the upper end of the chassis is fixedly connected to the upper base plate via a plurality of evenly distributed support columns, a plurality of symmetrically distributed adjustment blocks are rotatably connected to the upper base plate, the lower end of the adjustment block is cooperated with an angle adjustment component, the angle adjustment component is used to adjust the angle between the adjustment block and the upper base plate, the adjustment block is fixedly connected to a cavity block, the inner wall of the cavity block is cooperated with a clamping component, and the clamping component is fixedly connected to the helium balloon via a rope.

[0008] According to a further technical solution, a connecting rod is fixedly connected between the two sliding rods, an electric telescopic rod is fixedly connected to the lower end surface of the upper base plate, and a driving end of the electric telescopic rod is fixedly connected to the connecting rod.

[0009] A further technical solution is that the clamping assembly includes a clamping block, a rotating plate, a placement groove, a rotating rod, a threaded rod, a ring, a base and a clamping plate; a symmetrically distributed clamping plate is fixedly connected between the upper ends of the inner walls of the cavity blocks; a threaded rod is slidably sleeved on the upper end of the clamping block, and a ring is slidably connected on the threaded rod, and a symmetrically distributed placement groove is opened on the clamping block, and the lower ends of the inner walls of the placement grooves are rotatably connected to the rotating plates, the upper ends of the rotating plates are fixedly connected to the base, and a rotating rod is rotatably connected between the base and the ring, a rope is bound to the outer wall of the threaded rod, and one end of the rope is located between the ring and the upper end of the clamping block.

DETAILED DESCRIPTION

[0016] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0017] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0018] like Figure 1-5 As shown, an embodiment of the present invention provides a high-load rotor UAV 1 equipped with a helium lift device, including a rotor UAV 1, a base frame 2, a support column 3, an upper base plate 4, a rope 9 and a helium balloon 10, wherein the upper end of the rotor UAV 1 is fixedly connected to the base frame 2, the upper end of the base frame 2 is fixedly connected to the upper base plate 4 through a plurality of evenly distributed support columns 3, a plurality of symmetrically distributed adjustment blocks 5 are rotatably connected to the upper base plate 4, the lower end of the adjustment block 5 is cooperated with an angle adjustment component 7, the angle adjustment component 7 is used to adjust the angle between the adjustment block 5 and the upper base plate 4, the adjustment block 5 is fixedly connected to a cavity block 6, the inner wall of the cavity block 6 is cooperated with a clamping component 8, and the clamping component 8 is fixedly connected to the helium balloon 10 through a rope 9.

[0019] Specifically, the helium balloon 10 is used to significantly improve the load capacity of the rotor UAV 1, enabling it to perform complex tasks such as high loads and long distances; the angle between the fixed rod and the upper base plate 4 can be adjusted through the angle adjustment component 7, so as to maintain a dynamic balance with the helium balloon 10. This adjustment helps to reduce vibration and turbulence during flight and improve flight stability; the helium balloon 10 can be quickly installed and disassembled through the snap-on component 8, which simplifies the installation and disassembly process of the helium balloon 10, thereby improving operational convenience and maintenance efficiency.

[0020] It is understandable that when subjected to external interference (such as wind), the helium balloon 10 drives the adjustment block 5 and the cavity block 6 to move around the upper base plate 4 through the rope 9 and the clamping assembly 8, and then drives the rotor UAV 1 to move through the base frame 1 and the support column 3, which may cause the rotor UAV 1 to tilt. By setting an angle adjustment assembly 7 between the adjustment block 5 and the upper base plate 4 to adjust the angle between the adjustment block 5 and the upper base plate 4, the flight stability state of the rotor UAV 1 can be effectively controlled.

[0021] like Figure 2-4 As shown, the angle adjustment assembly 7 includes a slide groove 71, a slide rod 72, a tooth groove 73, a ring tooth 74 and a ring groove 75; a slide groove 71 is provided on the support columns 3 on both sides of the upper base plate 4, and the inner wall of the slide groove 71 of the support column 3 on the same side is slidably connected with a slide rod 72, and the slide rod 72 is provided with a tooth groove 73; a ring groove 75 is provided on one side of the lower end of the adjustment block 5, and the inner wall of the ring groove 75 is fixedly connected with a ring tooth 74, and the ring tooth 74 is meshed with the tooth groove 73.

[0022] Furthermore, a connecting rod 76 is fixedly connected between the two sliding rods 72 , and an electric telescopic rod 77 is fixedly connected to the lower end surface of the upper base plate 4 , and a driving end of the electric telescopic rod 77 is fixedly connected to the connecting rod 76 .

[0023] Specifically, when the drone needs to adjust its angle with the horizontal plane, the electric telescopic rod 77 is controlled to extend and retract, and then the driving end of the electric telescopic rod 77 drives the sliding rods 72 on both sides to slide along the inner wall of the slide groove 71 through the connecting rod 76, and then the sliding rod 72 drives the ring gear 74 to rotate through the tooth groove 73, and then the ring gear 74 drives the adjustment block 5 to rotate, thereby adjusting the angle between the upper base plate 4 and the adjustment block 5, and then adjusting the angle between the upper base plate 4 and the horizontal plane.

[0024] like Figure 1 , Figure 3 and Figure 5As shown, the clamping assembly 8 includes a clamping block 81, a rotating plate 82, a placement groove 83, a rotating rod 84, a threaded rod 85, a ring 86, a base 89 and a clamping plate 810; a symmetrically distributed clamping plate 810 is fixedly connected between the upper ends of the inner walls of the cavity block 6; a threaded rod 85 is slidably sleeved on the upper end of the clamping block 81, and a ring 86 is slidably connected on the threaded rod 85. The clamping block 81 is provided with symmetrically distributed placement grooves 83, and the lower ends of the inner walls of the placement grooves 83 are rotatably connected to the rotating plates 82, the upper ends of the rotating plates 82 are fixedly connected to the base 89, and the rotating rod 84 is rotatably connected between the base 89 and the ring 86, the outer wall of the threaded rod 85 is bound with a rope 9, and one end of the rope 9 is located between the ring 86 and the upper end of the clamping block 81.

[0025] It can be seen that the rope 9 can also be fixed to the outer wall of the threaded rod 85 by a fixing device.

[0026] Furthermore, a threaded cap 88 is threadedly connected to the outer wall of the threaded rod 85 , and the threaded cap 88 is located at the upper end of the collar 86 . A first spring 87 is fixedly disposed between the rotating plate 82 and the inner wall of the placement groove 83 .

[0027] Furthermore, a receiving plate 12 is slidably connected to the inner wall of the cavity block 6 , and a second spring 11 is fixedly arranged between the receiving plate 12 and the top of the adjustment block 5 .

[0028] Specifically, release the threaded nut 88, and then snap the clamping block 81 into the cavity block 6. During the descending process of the clamping block 81, the clamping plate 810 pushes the rotating plate 82 to compress the first spring 87 until the rotating plate 82 is separated from the clamping plate 810. Then, the rotating plate 82 is rotated open under the elastic action of the first spring 87 and is clamped between the clamping plate 810 and the inner wall of the cavity block 6, and then the threaded nut 88 is tightened. When the clamping assembly 8 needs to be removed, first release the threaded nut 88, then press the clamping block 81 downward until the rotating plate 82 is separated from the clamping plate 810, and then pull the ring 86 upward. The ring 86 drives the rotating plate 82 to approach the inner wall of the placement groove 83 through the rotating rod 84, and then pull the clamping block 81 upward.

[0029] The working principle of the present invention is as follows: release the threaded cap 88, then snap the clamping block 81 into the cavity block 6, during the descending process of the clamping block 81, the clamping plate 810 pushes the rotating plate 82 to compress the first spring 87 until the rotating plate 82 is separated from the clamping plate 810, and then the rotating plate 82 is rotated open under the elastic action of the first spring 87 to be clamped between the clamping plate 810 and the inner wall of the cavity block 6, and then the threaded cap 88 is tightened; when it is necessary to remove the clamping assembly 8, first release the threaded cap 88, then press the clamping block 81 downward until the rotating plate 82 is separated from the clamping plate 810, and then pull the collar 86 upward, and the collar 86 drives the rotating plate 82 to approach the placement groove 83 through the rotating rod 84. The wall is then pulled out of the clamping block 81 upwards; when the drone needs to adjust the angle with the horizontal plane, the electric telescopic rod 77 is controlled to extend and retract, and then the driving end of the electric telescopic rod 77 drives the sliding rods 72 on both sides to slide along the inner wall of the slide groove 71 through the connecting rod 76, and then the sliding rod 72 drives the ring gear 74 to rotate through the tooth groove 73, and then the ring gear 74 drives the adjusting block 5 to rotate, thereby adjusting the angle between the upper base plate 4 and the adjusting block 5, and then adjusting the angle between the upper base plate 4 and the horizontal plane; in addition, during the flight, the second spring 11 pushes the receiving plate 12 to squeeze the clamping block 81 upwards, so that the rotating plate 82 is firmly fixed between the clamping plate 810 and the inner wall of the cavity block 6.
