Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicle (UAV) inspection, in particular to an inspection UAV suitable for mountain power lines. Background Art

[0002] Traditional power line inspection methods mainly rely on manual walking or helicopter operations. However, in complex terrains such as mountains, these methods have problems such as low efficiency, high cost, and high safety risks. In recent years, with the development of UAV technology, using UAVs for power line inspection has gradually become an effective alternative.

[0003] For example, a UAV landing gear suitable for flying in mountains with the authorization publication number CN105857585B includes a landing plate, a storage box, a support device, and an opening and closing device. The landing plate has a square structure, and card seats are symmetrically arranged on both left and right sides of the landing plate, and the cross-section of the card seat is in a "Ω" shape. The storage box is fixed on the bottom surface of the landing plate and consists of an outer frame and an inner frame. The outer frame and the inner frame enclose a connected "回" - shaped storage groove. The support device is arranged end to end in the connected "回" - shaped storage groove formed by the outer frame and the inner frame, and the opening and closing device is symmetrically arranged at the lower end of the storage box. This patent compensates for the height difference caused by uneven ground by using the support device, provides convenience for the take - off and landing of UAVs in mountainous areas or on uneven ground, has strong applicability and good shock absorption effect, and avoids the phenomenon that the UAV is damaged or broken due to emergency landing in mountainous areas or on uneven ground. However, due to the fixed height of this device, it can only support the UAV for take - off and landing on the ground. When the UAV takes off and lands in the mountains, it is easily blocked by forest trees and causes collision damage.

[0004] Therefore, an inspection UAV suitable for mountain power lines has been developed, which can enable the UAV to take off and land above the forest and avoid being interfered by trees. Content of the Utility Model

[0005] In order to overcome the shortcoming of the existing UAV landing gear that can only support the UAV for take - off and landing on the ground, and when the UAV takes off and lands in the mountains, it is easily blocked by forest trees and causes collision damage, the utility model provides an inspection UAV suitable for mountain power lines, which can enable the UAV to take off and land above the forest and avoid being interfered by trees.

[0006] A drone for inspecting power lines in mountainous areas includes a base, a multi-stage cylinder, a shell, a fixed handle, a drone, a landing gear, a charging component, and an inspection component.

Fixed handles are connected to the upper side of the shell, and the fixed handles are interlocked. The drone is located in the middle of the base. Landing gears are connected to the lower left and right sides of the drone. The landing gears are equipped with a charging component for charging the drone. The drone is equipped with an inspection component for omnidirectional inspection of power lines.

[0007] Optionally, it also includes protective frames, with multiple protective frames attached to the upper part of the drone.

[0008] Optionally, the charging assembly includes charging contacts, a charging plate, a first spring, and a second spring. Charging contacts are connected to the lower sides of both the front and rear of the landing gear. The charging contacts are connected to the drone via wires. A charging plate is slidably connected to the upper side of the middle of the base. A second spring is connected between the middle of the charging plate and the base. Multiple first springs are connected between the charging plate and the base. The drone is placed on the charging plate via the landing gear.

[0009] Optionally, the inspection component includes a fixed frame, a first connecting frame, a mounting frame, fixing bolts, a protective shell, a second connecting frame, a third connecting frame, a first motor, a gear, a gear ring, a second motor, and a camera. The fixed frame connects the landing gears, and the first connecting frame is connected to the lower side of the fixed frame. The mounting frame is detachably connected to the first connecting frame via two fixing bolts on the left and right sides. The protective shell is snapped onto the first connecting frame.

The base 1 is connected to the telescopic end of the multi-stage cylinder 101. The housing 2 is rotatably connected to both sides of the base 1. The fixed handles 3 are connected to the upper side of the housing 2 and are interlocked with each other. The drone 4 is located in the middle of the base 1. The landing gear 5 is connected to the lower sides of both sides of the drone 4. Four protective frames 10 are connected to the upper part of the drone 4. The charging component is located on the landing gear 5, and the inspection component is located on the drone 4.

[0022] like Figure 3As shown, the charging assembly includes charging contacts 6, a charging plate 7, a first spring 8, and a second spring 9. The lower sides of both the front and rear parts of the landing gear 5 are connected to the charging contacts 6, and the charging contacts 6 are all connected to the drone 4 via wires. The charging plate 7 is slidably connected to the upper side of the middle part of the base 1. The middle part of the charging plate 7 is connected to the base 1 via a second spring 9. Four first springs 8 are connected between the charging plate 7 and the base 1. The drone 4 is placed on the charging plate 7 via the landing gear 5.

[0023] like Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, the inspection assembly includes a fixed frame 11, a first connecting frame 12, a mounting frame 121, fixing bolts 13, a protective shell 14, a second connecting frame 15, a third connecting frame 151, a first motor 16, a gear 161, a gear ring 162, a second motor 17, and a camera 18. The fixed frame 11 connects the landing gears 5. The first connecting frame 12 is connected to the lower side of the fixed frame 11. The mounting frame 121 is detachably connected to the first connecting frame 12 via two left and right fixing bolts 13. The protective shell 14 is snapped onto the first connecting frame 12. The protective shell 14 is made of transparent material for easy inspection. The second connecting frame 151 is connected to the lower side of the middle of the fixed frame 11. Two connecting frames 15 are connected, and a third connecting frame 151 is rotatably connected to the second connecting frame 15. A first motor 16 is connected inside the second connecting frame 15. A gear 161 is connected to the output shaft of the first motor 16. A gear ring 162 is connected to the upper part of the third connecting frame 151. The gear 161 meshes with the gear ring 162.

Then the second motor 17 is started, driving the camera 18 to rotate, so that the camera 18 can rotate at multiple angles to inspect the power line.

[0026] When the drone 4 lands on the base 1, the charging contact 6 on the landing gear 5 contacts the charging plate 7 to charge the drone 4. The charging plate 7 is buffered by the force of the first spring 8 and the second spring 9. When the camera 18 needs to be inspected, the fixing bolt 13 and the mounting bracket 121 can be removed, and the protective shell 14 can be removed from the first connecting bracket 12.
