Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a UAV mounting device for inspecting power lines in forests. Background Technology

[0002] In today's power systems, transmission lines, as the key carriers of power transmission, play a decisive role in the reliability of the entire power grid due to their safe and stable operation. However, mountainous areas are characterized by rugged terrain and inconvenient transportation, making traditional manual inspection methods extremely inefficient. Inspection personnel not only need to spend a lot of time and energy trekking through difficult mountain paths, but also face significant safety risks when manually inspecting towering power poles and complex wiring equipment at close range. Furthermore, due to the dense vegetation in mountainous environments, some lines may be obscured, making it difficult for manual inspections to comprehensively and promptly identify potential problems.

[0003] With the development of technology, drone technology is gradually being applied to the field of power line inspection. Drones can quickly reach designated locations in mountainous areas, without being limited by terrain, greatly improving inspection efficiency. However, in practical applications, some existing drone mounting devices, when the drone stops for equipment replacement or refueling, cause the drone's center of gravity to shift due to the limitations of mountainous terrain and the different centers of gravity of the mounting equipment. This can lead to the drone tipping over, affecting the continuity and safety of operations. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a drone mounting device for inspecting power lines in mountainous areas. It aims to solve the problem that when the drone is stopped for equipment replacement or refueling, the drone's center of gravity shifts due to terrain limitations and the different centers of gravity of the mounted equipment, causing the drone to easily tip over and affecting the continuity and safety of the operation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drone mounting device for detecting power line equipment in forest areas, comprising a sliding plate, an electric track on the lower side of the sliding plate, the output end of the electric track for fixing the mounting device, a drive assembly on the upper side of the sliding plate, arc-shaped hanging rods at both ends of the drive assembly, a sliding rod fixedly connected between the two arc-shaped hanging rods, the sliding rod passing through the sliding plate and slidably connected to the sliding plate, support legs rotatably connected to both ends of the arc-shaped hanging rods, a rotating mechanism on the arc-shaped hanging rods, the output end of the rotating mechanism fixedly located at the upper end of the support leg, a pressure sensing device on the end of the support leg away from the rotating mechanism, and the tops of the two arc-shaped hanging rods for fixed connection to the drone.

[0006] Furthermore, the rotating mechanism includes a rotating component and a motor. The motor is mounted on the arc-shaped hanging rod, and the output end of the motor is fixedly connected to the rotating component. The support leg is fixedly connected to one side of the rotating component.

[0007] Furthermore, the rotating assembly includes gear one and gear two. The output end of motor one is fixedly disposed on one side of gear one. The tooth end of gear one is meshed with gear two. Both sides of gear two are rotatably connected to the inner sidewall of the arc-shaped hanging rod. The side of gear two away from gear one is fixedly connected to the support leg.

[0008] Furthermore, both ends of the arc-shaped hanging rod are provided with grooves, the first gear is located inside the groove, and the two sides of the second gear are rotatably connected to the side wall between the two sides of the groove.

[0009] Furthermore, the drive assembly includes a lead screw and a second motor. The two ends of the lead screw are rotatably connected to the side wall between two arc-shaped hanging rods, and the output end of the lead screw is fixedly connected to the upper side of the slide plate. The second motor is disposed on the outer wall of one of the arc-shaped hanging rods, and the output end of the second motor is connected to one end of the lead screw.

[0010] Furthermore, the lower end of the support leg is provided with a support foot, and the pressure sensing device is located between the support leg and the support foot.

[0011] Furthermore, a connecting rod is fixedly connected to the upper end of the support leg, and the upper end of the connecting rod is fixedly connected to the side of gear two away from gear one.

[0012] Furthermore, a hanging plate is fixedly connected to the output end of the electric track, and a connecting plate is provided on the lower side of the hanging plate. The lower side of the connecting plate is used to fix the mounting equipment, and the hanging plate and the connecting plate are connected by fastening bolts.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, the center of gravity of the drone is lowered by driving the rotating mechanism, rotating the support legs and the arc-shaped hanging rod, and combining the control of the drone and the detection of the pressure sensing device. By driving the drive component and the electric track, sliding the sliding rod and the sliding plate, and supporting the mounted equipment by the electric track, the problem of the drone's center of gravity shifting due to terrain limitations and the different center of gravity of the mounted equipment when the drone is stopped for equipment replacement or energy replenishment is solved. This causes the drone to easily tip over, affecting the continuity and safety of the operation.

[0015] 2. In this utility model, the arc-shaped hanging rod provides support for the motor, and the output end of the motor drives the gear one to rotate, which in turn drives the gear two to rotate. Through the connection between the gear two and the support leg, and the rotational connection between the gear two and the arc-shaped hanging rod, the rotation mechanism drives the support leg, thereby realizing the relative rotation between the support leg and the arc-shaped hanging rod.

[0016] 3. In this utility model, the arc-shaped hanging rod provides support for the second motor. The rotation of the lead screw is achieved by driving the output end of the second motor and rotating the lead screw and the arc-shaped hanging rod. The sliding connection between the sliding rod and the sliding plate is achieved by driving the output end of the electric track, thereby realizing the adjustment of the center of gravity of the UAV after the mounting equipment is installed.

Detailed Implementation

[0024] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of a drone mounting device for detecting power line equipment in mountainous areas, including a sliding plate 9. An electric track 14 is provided on the lower side of the sliding plate 9. The output end of the electric track 14 is used to fix a mounting device 8. A drive assembly 5 is provided on the upper side of the sliding plate 9. Arc-shaped hanging rods 3 are provided at both ends of the drive assembly 5. A sliding rod 4 is fixedly connected between the two arc-shaped hanging rods 3, passing through the sliding plate 9 and slidably connected to it. Support legs 1 are rotatably connected to both ends of the arc-shaped hanging rods 3. A rotating mechanism 2 is provided on the arc-shaped hanging rods 3. The output end of the rotating mechanism 2 is fixedly located at the upper end of the support leg 1. A pressure sensing device 13 is provided at the end of the support leg 1 away from the rotating mechanism 2. The tops of the two arc-shaped hanging rods 3 are used to fix them to the drone.

[0026] In this embodiment, Figure 1 The directions are front, back, left, and right. The electric track 14 is an electric track with a locking function, such as electromagnetic locking or mechanical braking. The output end of the electric track moves along the length of the electric track 14. The mounting device 8 is a detection device carried by the UAV. It can be any device that can be mounted by the UAV and applied to the detection of wire equipment. No specific limitation is made here.

[0027] Specifically, the aforementioned mounting device is connected to the drone via the arc-shaped hanging rod 3. When the drone needs to change equipment or recharge, it lands. At this time, the end of the support leg 1 furthest from the rotating mechanism 2 is lower than the lower end of the arc-shaped hanging rod 3. Depending on the terrain slope, the support legs 1 at different positions contact the ground at different times. The pressure sensor 13 detects the pressure on the lower end of the support leg 1 in real time. The support leg 1 that contacts the ground first, under the reaction force of the ground, causes the pressure sensor 13 to detect the pressure between the support leg 1 and the ground in real time and transmit the data to the drone. The drone controls the rotating mechanism 2 on the support leg 1 that contacts the ground to drive it. Through the rotating connection between the support leg 1 and the arc-shaped hanging rod 3, the lower end of the support leg 1 that contacts the ground rotates upward, keeping the pressure within a certain range. The remaining support legs 1 contact the ground in sequence. Through the adjustment of the rotating mechanism 2, the pressure between each support leg 1 and the ground is maintained within a certain range until the drone lands. At this time, the support legs 1 support the drone. By spreading the four support legs 1, the center of gravity of the drone is lowered, thereby improving the stability of the drone.

[0028] Next, there are two sliding bars 4, located at both ends of the sliding plate 9. The replacement mounting device 8 is connected to the output end of the electric track 14, and the drone is started, causing it to rise and leave the ground. If the mounting device 8 causes the drone's center of gravity to shift, the drone control drive component 5 can be used to drive the sliding plate 9 to move horizontally between the two arc-shaped hanging bars 3. The two sliding bars 4 can improve the stability of the sliding plate 9 when it slides. In addition, the electric track 14 drives the mounting device 8 to move horizontally between the two sliding bars 4, thereby adjusting the position of the mounting point of the mounting device 8. This achieves the adjustment of the drone's center of gravity, solving the problem that when the drone is stopped for equipment replacement or recharging, the drone's center of gravity shifts due to terrain limitations and the different center of gravity of the mounting device 8, which can easily cause the drone to tip over, affecting the continuity and safety of the operation.

[0029] Reference Figure 1 The rotating mechanism 2 includes a rotating component 20 and a motor 21. The motor 21 is mounted on the arc-shaped hanging rod 3. The output end of the motor 21 is fixedly connected to the rotating component 20. The support leg 1 is fixedly connected to one side of the rotating component 20.

[0030] Specifically, motor 21 is a servo motor or stepper motor with brake. The arc-shaped hanging rod 3 provides support for motor 21 and rotating component 20. Motor 21 drives rotating component 20 to rotate, and rotating component 20 drives support leg 1 to rotate, realizing the relative rotation between support leg 1 and arc-shaped hanging rod 3, thereby realizing the function of rotating mechanism 2 driving support leg 1.

[0031] Reference Figure 1 The rotating assembly 20 includes a first gear 200 and a second gear 211. The output end of the first motor 21 is fixedly disposed on one side of the first gear 200. The tooth end of the first gear 200 meshes with the second gear 211. Both sides of the second gear 211 are rotatably connected to the inner side wall of the arc-shaped hanging rod 3. The side of the second gear 211 away from the first gear 200 is fixed to the support leg 1.

[0032] Specifically, the arc-shaped hanging rod 3 provides support for gear 211. The output of motor 21 drives gear 200 to rotate, which in turn drives gear 211 to rotate. Gear 211 then drives the support leg 1 to rotate, thus enabling the support leg 1 to rotate relative to the arc-shaped hanging rod 3. Gear 200 and gear 211 form a reduction gear set, improving the driving torque and stability of the support leg 1.

[0033] Reference Figure 1 Both ends of the arc-shaped hanging rod 3 are provided with grooves 7. Gear 1 200 is located inside the groove 7, and gear 211 is rotatably connected to the side wall between the two sides of the groove 7.

[0034] Specifically, the arc-shaped hanging rod 3 provides support for the groove 7. The design of the groove 7 provides space for the rotation of gear 1 200 and gear 2 211, and increases the stability of the rotation of the support leg 1, thereby helping to improve the relative rotation stability of the support leg 1 and the arc-shaped hanging rod 3.

[0035] Reference Figure 1 The drive assembly 5 includes a lead screw 50 and a second motor 51. The two ends of the lead screw 50 are rotatably connected to the side wall between two arc-shaped hanging rods 3. The output end of the lead screw 50 is fixedly connected to the upper side of the slide plate 9. The second motor 51 is installed on the outer wall of one of the arc-shaped hanging rods 3, and the output end of the second motor 51 is connected to one end of the lead screw 50.

[0036] Specifically, motor 51 is a servo motor or stepper motor with braking function. The output end of the lead screw 50 is a nut structure fixed to the top of the slide plate 9 and adapted to the lead screw 50. The two ends of the lead screw 50 are rotatably connected to the arc-shaped hanging rods 3. The output end of motor 51 is fixedly connected to one end of the lead screw 50 to drive the lead screw 50 to rotate, so that the output end of the lead screw 50 moves horizontally between the two arc-shaped hanging rods 3, thereby driving the slide plate 9 to move horizontally between the two arc-shaped hanging rods 3, which helps to adjust the center of gravity of the UAV.

[0037] Reference Figure 1 and Figure 3 The lower end of the support leg 1 is provided with a support foot 6, and the pressure sensor 13 is located on the side wall between the support leg 1 and the support foot 6.

[0038] Specifically, the outer wall of the support leg 6 is made of rubber, and the pressure sensing device 13 is a pressure sensor. When in contact with the ground, the pressure sensing device 13 can detect the pressure between the support leg 6 and the support leg 1, thereby realizing the function of real-time detection of the pressure between the support leg 1 and the ground by the pressure sensing device 13.

[0039] Reference Figure 1 and Figure 5 A connecting rod 15 is fixedly connected to the upper end of the support leg 1. The upper end of the connecting rod 15 is fixedly connected to the side of the gear 211 away from the gear 1 200.

[0040] Specifically, gear 211 has a socket on the side away from gear 1 200. The connecting rod 15 is inserted into the socket and fixedly connected to gear 211, making installation convenient.

[0041] Reference Figure 1 and Figure 4 The output end of the electric track 14 is fixedly connected to a hanging plate 11. A connecting plate 12 is provided on the lower side of the hanging plate 11. The lower side of the connecting plate 12 is used to fix the mounting equipment 8. The hanging plate 11 and the connecting plate 12 are connected by fastening bolts 10.

[0042] Specifically, the output end of the electric track 14 provides support for the mounting plate 11. When replacing or installing the mounting equipment 8, the mounting plate 11 and the connecting plate 12 can be quickly installed and removed by fastening bolts 10, thus realizing the convenience of installing or replacing the mounting equipment 8.

[0043] Working principle: When the drone needs to change equipment or recharge, it lands. Depending on the terrain slope, the support legs 6 at different positions will contact the ground at different times. The pressure sensor 13 detects the pressure between the support legs 1 and the support legs 6 in real time. The support leg 1 that contacts the ground first is driven by the output of motor 21 to rotate gear 200. Gear 200 drives gear 211 to rotate, which in turn drives the support leg 1 to rotate relative to the arc-shaped hanging rod 3. This keeps the pressure detected by the pressure sensor 13 within a certain range. The remaining support legs 1 contact the ground in sequence, and the pressure between each support leg 1 and the ground is maintained within a certain range until the drone lands. At this time, the support legs 1 support the drone. By spreading the four support legs 1, the center of gravity of the drone is lowered, thereby improving the stability of the drone.

[0044] Then, the replacement mounting device 8 is installed on the output end of the electric track 14. The drone is started and raised off the ground. Through the drone control, the output end of motor 2 51 drives the lead screw 50 to rotate. The output end of the lead screw 50 drives the slide plate 9 to move horizontally between the two arc-shaped hanging rods 3. Through the drive of the electric track 14, the mounting device 8 moves horizontally between the two sliding rods 4, thereby completing the adjustment of the mounting point position of the mounting device 8. This solves the problem that when the drone stops to replace equipment or replenish energy, the drone's center of gravity shifts due to terrain limitations and the different center of gravity of the mounting device 8, which can easily cause the drone to tip over, affecting the continuity and safety of the operation.

[0045] The aforementioned motor 21, motor 51, pressure sensor 13, and electric track 14 can be wirelessly connected to the drone, via Bluetooth technology. Alternatively, wire contacts can be installed on the arc-shaped hanging rod 3 to achieve a wired connection with the drone. The specific connection control method can use any feasible method from the prior art, as it is not the focus of this application and therefore will not be specifically explained or limited.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
