Description

Technical Field

[0001] This invention relates to the field of unmanned aerial vehicle (UAV) inspection technology for power distribution lines, and in particular to a power distribution line detection device with an alarm function. Background Technology

[0002] Traditional power distribution line inspection methods primarily rely on manual climbing of poles for visual inspection and simple tool-assisted checks. This approach has several drawbacks: firstly, it is extremely inefficient, especially when dealing with long-distance, large-scale power distribution networks, requiring significant manpower, resources, and time; secondly, it carries high safety risks, with inspectors facing dangers such as falls and electric shock while working at heights. Furthermore, while some companies have attempted to use ordinary drones for inspection, practical applications have revealed that the accumulation of dirt on the line surfaces results in poor image quality from the acquisition equipment, affecting the accurate assessment of the line's condition. Moreover, the lack of effective cleaning methods prevents the timely removal of contaminants, leading to unsatisfactory subsequent inspection results.

[0003] A search revealed Chinese patent application CN202222786051.4, which discloses an intelligent inspection drone with obstacle avoidance capabilities.

[0031] The beneficial effects of this invention are as follows:

[0032] 1. This invention, by setting up an image acquisition mechanism, can acquire image information in real time, so as to detect abnormal situations and trigger alarms through image analysis; by setting up a cleaning mechanism, it can supply air to the annular air chamber and the annular seat based on the operation of the air pump, and then output the airflow through the air blowing pipe through various connecting pipes, thereby cleaning the power distribution lines and their corresponding facilities with air, achieving the purpose of maintenance, and at the same time, it can facilitate the acquisition of clearer images.

[0033] 2. By setting up a toggle component, the present invention can periodically toggle the air tube based on the toggle component. With the cooperation of the first spherical body moving within the first ball seat, the angle of the air tube is changed. When the toggle component disengages from the air tube, the structure can be reset based on the rebound force of the first annular elastic connection, thereby improving the range of air cleaning and enhancing practicality.

[0034] 3. This invention, by setting up a ring seat rotatably mounted inside the ring-shaped air chamber, and a slide and other structures, can, as needed, drive the ring base to descend based on the operation of the lifting control component, and then use the lever to press the air pipe downward, thereby causing the positioning post to be locked into the positioning groove, limiting the deflection of the air pipe; at the same time, based on the operation of the rotation drive motor, the ring rotating frame is driven to rotate, and the air pipe is synchronously moved by the lever. Since the air pipe is limited, the ring mounting platform can rotate with the rotation of the ring rotating frame; since the slide is installed in the guide frame, the ring seat can rotate synchronously. At this time, when the air pipe is spraying air for cleaning, the expanded air spray range and the cooperation of each air pipe can achieve more efficient air spray cleaning.

[0035] 4. By setting up structures such as an annular limiting frame and positioning blocks, this invention enables the positioning block to be locked in the slot of the annular positioning frame by the force of the second spring when no external force is applied, thus maintaining the stability of the annular seat and preventing the annular seat from moving when the paddle moves the air pipe. When the lifting and adjusting motor controls the annular base to descend, the slide slides downwards while pressing the annular limiting frame downwards, thereby causing the positioning block to disengage from the slot, unlocking the annular seat, allowing the structure to rotate, meeting the operational requirements, and improving reliability.

[0036] 5. This invention, by setting up a spraying mechanism, can spray paint through a spraying pipe based on the operation of a paint delivery pump, and spray paint onto the structure to achieve maintenance operations; for example, uniformly applying bird-repellent paint to the surface of a tower crossarm; by setting up structures such as a second spherical body, a second annular elastic connecting part, and a lever, the spraying area can be expanded by using the synchronous rotation of the annular limit frame when the annular seat rotates and periodically moving the spraying pipe through the lever; the entire scheme is based on the same set of mechanisms: annular mounting platform, annular seat, annular limit frame, etc., to achieve different operating modes.

Detailed Implementation

[0046] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0047] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0048] Example 1:

[0049] A power distribution line detection device with alarm function, such as Figure 1-8 As shown, the drone includes a main body 1, an image acquisition mechanism and a cleaning mechanism are installed at the bottom of the main body 1, and an image analysis module, an alarm module and a remote transmission module are installed inside the main body 1.

[0050] The image acquisition mechanism acquires image information in real time, the image analysis module processes and analyzes the acquired image information, the alarm module determines whether to generate alarm information based on the analysis results, and the remote transmission module is used to transmit image information and alarm information. The implementation methods of each module, such as communication methods, image processing methods, etc., can refer to existing technologies and will not be elaborated here.

[0051] The cleaning facility includes:

[0052] An annular air chamber 11 is mounted on the bottom of the UAV body 1 via a bracket. An annular seat 39 is installed inside the annular air chamber 11, and the annular air chamber 11 is connected to the inside of the annular seat 39. An air pump is installed inside the UAV body 1, and the output end of the air pump is connected to the inside of the annular air chamber 11 via an air delivery pipe 21.

[0053] An annular mounting platform 48 is installed inside the annular seat 39. The annular mounting platform 48 is provided with a first ball seat 47 distributed in a circle. A first spherical body 9 is movably installed inside the first ball seat 47. An air blowing pipe 17 is provided through the center of the first spherical body 9. The air blowing pipe 17 is slidably installed at the center of the first spherical body 9. The top end of the air blowing pipe 17 is connected to the inside of the annular seat 39 through a connecting pipe 26.

[0054] Mounting plate 36 is fixed to the outside of air pipe 17, and mounting plate 36 and first ball seat 47 are connected by first annular elastic connection part 22.

[0055] A toggle assembly for periodically toggling the air tube 17;

[0056] This solution is applicable to outdoor power distribution line inspection. By setting up an image acquisition mechanism, it can acquire image information in real time, so as to detect abnormalities and trigger alarms through image analysis. By setting up a cleaning mechanism, it can supply air into the annular air chamber 11 and the annular seat 39 based on the operation of an air pump, and then output the airflow through the blowing pipe 17 through various connecting pipes 26, thereby cleaning the power distribution line and its corresponding facilities with air to achieve the purpose of maintenance, while also facilitating the acquisition of clearer images.

[0057] By setting a toggle component, the air tube 17 can be periodically toggled based on the toggle component. With the cooperation of the first spherical body 9 moving within the first ball seat 47, the angle of the air tube 17 can be changed. When the toggle component disengages from the air tube 17, the structure can be reset based on the rebound force of the first annular elastic connection 22, thereby increasing the range of air cleaning and improving practicality.

[0058] To facilitate the manipulation of the air tube 17; such as Figure 3 , Figure 4 As shown, the toggle assembly includes:

[0059] An annular base 20 is positioned below the main body 1 of the drone.

[0060] The annular rotating frame 15 is rotatably mounted on the annular base 20. Multiple levers 19 are mounted on the top of the annular rotating frame 15, and the air blowing pipe 17 is located on the movement path of the levers 19.

[0061] A rotation drive unit is installed at the bottom of the UAV body 1 and is used to drive the ring rotating frame 15 to rotate.

[0062] To facilitate the rotation of the annular rotating frame 15; such as Figure 4 As shown, the rotation drive unit includes a rotation drive motor 25, which is mounted on an annular base 20 via a bracket. The output end of the rotation drive motor 25 is connected to a rotation drive gear 14. The annular rotating frame 15 is provided with uniformly circumferentially distributed convex teeth 27, which mesh with the rotation drive gear 14.

[0063] By setting up a toggle assembly, the rotation drive motor 25 can work to drive the rotation drive gear 14 to rotate, which in turn drives the annular rotating frame 15 to rotate on the annular base 20, thereby using the toggle 19 to toggle the air pipe 17.

[0064] To achieve different cleaning modes; such as Figure 4 , Figure 6 As shown, the bottom of the UAV body 1 is provided with a lifting control component for controlling the lifting and lowering of the annular base 20. The annular base 39 is rotatably and sealably installed inside the annular air chamber 11. A slide 41 is installed on the outer side of the annular mounting platform 48. A guide frame 40 is installed on the side of the annular base 39 near the annular mounting platform 48. The slide 41 is slidably connected to the inner wall of the guide frame 40. The guide frame 40 and the slide 41 are connected by a first spring 42. Positioning posts 37 are provided on both sides of the bottom of the mounting plate 36. A positioning groove 38 adapted to the positioning posts 37 is opened on the annular mounting platform 48.

[0065] By setting up a ring seat 39 rotatably mounted inside the annular air chamber 11, and a slide 41 and other structures, the ring base 20 can be lowered as needed based on the operation of the lifting control component. Then, the paddle 19 is used to press the air pipe 17 downward, so that the positioning post 37 is locked into the positioning groove 38, limiting the deflection of the air pipe 17. At the same time, based on the operation of the rotation drive motor 25, the annular rotating frame 15 is driven to rotate, and the paddle 19 is used to paddle the air pipe 17 synchronously. Since the air pipe 17 is limited, the annular mounting platform 48 can rotate with the rotation of the annular rotating frame 15. Since the slide 41 is installed in the guide frame 40, the ring seat 39 can rotate synchronously. At this time, when the air pipe 17 is cleaning with air, the expanded air spray range and the cooperation of each air pipe 17 can achieve more efficient air spray cleaning.

[0066] To facilitate control of structural lifting; such as Figure 4 As shown, the lifting control component includes:

[0067] A lifting adjustment motor 10 is installed at the bottom of the drone body 1.

[0068] Guide rod 16, guide rod 16 is fixed to the bottom of the UAV body 1;

[0069] The lifting adjustment screw 35 has one end connected to the output end of the lifting adjustment motor 10. Two mounting plates 18 are installed on the top of the annular base 20. One mounting plate 18 is threaded to the outer wall of the lifting adjustment screw 35, and the other mounting plate 18 is slidably connected to the outer wall of the guide rod 16.

[0070] In order to maintain the stability of the ring seat 39 when it is not rotating; such as Figure 6 , Figure 7 , Figure 8 As shown, a guide post 45 is fixed to the bottom of the annular seat 39, and an annular limiting frame 13 is slidably connected to the outer wall of the guide post 45. The annular limiting frame 13 and the annular seat 39 are connected by a second spring 46. The annular limiting frame 13 is located directly below the slide 41. An annular positioning frame 43 is installed at the bottom of the annular air chamber 11, and a positioning block 44 is installed on the top of one side of the annular limiting frame 13. A slot adapted to the positioning block 44 is opened on the annular positioning frame 43. When no external force is applied, the positioning block 44 is locked in the slot of the annular positioning frame 43 based on the force of the second spring 46.

[0071] By setting up structures such as the annular limiting frame 13 and the positioning block 44, when no external force is applied, the positioning block 44 is locked in the slot of the annular positioning frame 43 based on the force of the second spring 46, keeping the annular seat 39 stable and preventing the annular seat 39 from moving when the lever 19 moves the air pipe 17; when the lifting adjustment motor 10 controls the annular base 20 to descend, the slide 41 slides down and can press the annular limiting frame 13 to move downward, thereby causing the positioning block 44 to disengage from the slot, unlocking the annular seat 39, allowing the structure to rotate, meeting the operational requirements, and improving reliability.

[0072] To facilitate maintenance work after spraying the coating; such as Figure 4 , Figure 5 As shown, a painting mechanism is installed at the bottom of the drone body 1. A paint tank and a paint delivery pump are installed inside the drone body 1. The output end of the paint tank is connected to the input end of the paint delivery pump. The painting mechanism includes:

[0073] Lifting guide rail 23 is installed at the bottom of the drone body 1, and lifting seat 34 is slidably connected to the lifting guide rail 23.

[0074] A lifting control motor 24 is installed at the bottom of the UAV body 1. The output end of the lifting control motor 24 is connected to a lifting control screw 29, which is threaded to the inner wall of the lifting seat 34.

[0075] Spraying pipe 28 is installed on one side of lifting base 34, and the top end of spraying pipe 28 is connected to the output end of paint delivery pump through paint delivery pipe 30.

[0076] By setting up a spraying mechanism, the paint can be sprayed out through the spraying pipe 28 based on the operation of the paint delivery pump, and the paint can be sprayed onto the structure to achieve maintenance operations; for example, uniformly applying bird-repellent paint to the surface of the crossarm of the tower.

[0077] To increase the coating area; such as Figure 3 , Figure 5 As shown, a lever 12 is installed at the bottom of the annular limiting frame 13, and a second ball seat 32 is installed on one side of the lifting seat 34. A second spherical body 31 is movably installed inside the second ball seat 32. The spraying pipe 28 passes through and is fixed at the center of the second spherical body 31. The outer side of the spraying pipe 28 is connected to the second ball seat 32 through a second annular elastic connecting part 33. The spraying pipe 28 is located on the movement path of the lever 12, and the end of the lever 12 has an arc-shaped structure to avoid the structure from jamming.

[0078] By setting up structures such as the second spherical body 31, the second annular elastic connecting part 33, and the lever 12, when the annular seat 39 rotates, the synchronous rotation of the annular limiting frame 13 is used to periodically move the spraying pipe 28 through the lever 12, thereby expanding the spraying area.

[0079] The entire solution is based on the same set of mechanisms: ring mounting platform 48, ring seat 39, ring limit frame 13, etc., to achieve different operating modes.

[0080] To facilitate image acquisition; such as Figure 2 As shown, the image acquisition mechanism includes a stand 8, which is installed at the bottom of the drone body 1. A camera support 7 is rotatably mounted on the stand 8 via a shaft. A camera 3 is installed inside the camera support 7. A camera adjustment motor 4 is installed on one side of the stand 8. The output end of the camera adjustment motor 4 is connected to the shaft of the camera support 7 via a transmission connection.

[0081] To enhance security; such as Figure 1 As shown, the bottom of the drone body 1 is provided with landing gear 2, and a ring-shaped protective net 6 is detachably installed on the arm of the drone body 1. The ring-shaped protective net 6 is located on the outside of the rotor 5 of the drone body 1.
