Description

Technical Field

[0001] The utility model belongs to the technical field of video detection devices, and particularly relates to an unmanned aerial vehicle power line inspection and monitoring device. Background Art

[0002] When drones are inspecting power lines, they usually use a monitoring device equipped with a camera to take pictures of the equipment on the power lines.

[0003] The installation conditions of power lines are very diverse. UAV inspection can work normally under extreme conditions such as cross-mountain areas, swamps, and high altitudes. Compared with traditional manual inspection methods, it can greatly reduce operation and maintenance costs, save inspection time, and improve inspection efficiency. Operation and maintenance personnel analyze the line equipment pictures collected by drones to determine whether the equipment has faults and defects. Since power line inspections have high requirements for image accuracy, when using drones for inspections, industrial cameras with high image quality, high resolution, and high color reproduction are usually equipped as camera equipment for monitoring devices. However, when drones encounter severe weather conditions (such as sand, dust, light rain, and fog) during inspections, existing camera equipment is prone to being unable to obtain clear and accurate image information due to dirty, foggy, and water droplets on the camera lens, making it difficult for operation and maintenance personnel to make accurate judgments on the operating status of the equipment based on the defective images taken.

[0004] In the prior art, the dust and water droplets on the camera are usually blown away by blowing air toward the camera, which has a certain cleaning effect, but for mixtures such as water and mud, it will cause the dirt area to expand and harden, making it more difficult to handle. In the patent document with application number CN2023105301998, a drone monitoring device based on intelligent control is disclosed, including a camera assembly, a blowing assembly that exhausts air toward the lens of the camera, and an outer covering decontamination assembly; the outer covering decontamination assembly includes a support frame fixed to the outer shell, two belt storage rollers, a cleaning belt, and a belt body lifting assembly; the cleaning belt is alternately provided with a permeable hole and a sheet body positioning hole, and each sheet body positioning hole is fixed with a rubber elastic disc with a self-adhesive layer on one side; the cleaning belt covers the lens to remove the stains attached to the lens, and the belt body lifting assembly lifts the cleaning belt in a timely manner by telescoping to keep it away from the lens, and the blowing assembly eliminates water vapor or fog in the lens by blowing out hot air. The above invention can have a good cleaning effect on stains such as dust, water droplets, and a mixture of dust and water. However, since it uses a cleaning tape with a self-adhesive sticker to remove stains, the self-adhesive sticker particles will remain on the lens after long-term use, affecting the clarity of the lens. In addition, the cleaning effect is relatively limited for some semi-dry or hardened water and dust mixtures with strong residual stains.

[0005] In view of this, the utility model proposes an unmanned aerial vehicle power line inspection and monitoring device, which can realize the self-cleaning of dirt on the lens of the mounted monitoring device when the unmanned aerial vehicle is conducting power line inspection, especially has a better cleaning effect on some semi-dry or hardened stubborn dirt, so as to solve the above-mentioned technical problems.

The first infrared radiating tube 103 and the second infrared radiating tube 104 are composed of an infrared emitting tube and an infrared receiving tube. Specifically, the infrared emitting tube and the infrared receiving tube of the first infrared radiating tube 103 are symmetrically arranged at the top of the shell 1, and are used to limit the highest position when the brush handle 19 moves upward. The infrared emitting tube and the infrared receiving tube of the second infrared radiating tube 104 are symmetrically arranged at the bottom of the shell 1, and are used to limit the lowest position when the brush handle 19 moves downward. The first infrared radiating tube 103, the second infrared radiating tube 104, The wireless communication module 105 is respectively connected to the main controller 100, the control ends of the micro water pump 14, the air pump 11, the motor 102, the first electric telescopic rod 23 and the second electric telescopic rod 16 are respectively connected to the output end of the motor drive circuit 101, the input end of the motor drive circuit 101 is connected to the controller 100, and the control end of the heating device 10 is connected to the controller 100. In this embodiment, the heating device 10 is composed of a heating wire and a temperature control circuit. The temperature control circuit is controlled by the controller 100 to adjust the temperature of the heating wire so that the heating device outputs hot air at 50°C. The main controller 100 can use a chip with model STM32F407ZGT6, and the wireless communication module 105 can use a communication module with model FS800E 4G.

[0039] When in use, the electrician mounts the utility model on the drone to inspect and shoot the power line, establishes communication with the wireless communication module 105 through the remote control device, and observes the shooting picture of the camera 3 of the utility model on the display screen of the remote control device. When stains are found on the lens of the camera 3, the electrician sends a cleaning command to the wireless communication module 105 by operating the remote control device. After receiving the command, the wireless communication module 105 sends the command to the main controller 100, and the main controller 100 drives each cleaning component to clean the lens of the camera 3 in sequence. The specific steps are as follows: ① The main controller 100 drives the motor drive circuit 101 to control the second electric telescopic rod 16 to retract upward, driving the second ring 18 to move upward in the inner cavity of the first ring 3, so that the bottom end of the second ring 18 leaves the lens of the camera 3. ② The main controller 100 drives the motor drive circuit 101 to control the micro water pump 14 to extract the cleaning liquid in the liquid storage tank 13, and then transports it to the spray plate 7 along the first conduit 12 and sprays it toward the brush head at the bottom of the brush handle 19 along the spray hole 8. ③ The main controller 100 drives the motor driving circuit 101 to control the motor 102 to rotate forward and reverse, driving the belt of the conveyor belt 9 to rotate up and down, thereby driving the brush handle 19 to move back and forth above the camera 3. When the brush handle 19 is observed to reach the lens of the camera 3, the power personnel remotely control the second electric telescopic rod 16 to extend downward through the remote control device, driving the second ring 18 to move downward, so that the second ring 18 applies a downward force to the brush handle 19, so that the brush head of the brush handle 19 is fully in contact with the lens of the camera 3, increasing the friction between the brush head and the lens of the camera 3, and improving the cleaning effect on stubborn stains. Part of the stains and moisture on the surface of the lens of the camera 3 flows into the first groove 20 along the curved surface of the lens, and flows into the second groove 21 along the first groove 20, and is discharged from the sewage outlet 24 under the action of gravity. While the belt of the conveyor belt 9 drives the brush handle 19 to move up and down, the main controller 100 recognizes that the brush handle 19 reaches the highest position and the lowest position set by the user through the infrared rays of the first infrared emitting tube 103 and the second infrared emitting tube 104, thereby controlling the forward and reverse rotation or stopping of the conveyor belt 9. The user can set the number of repetitions of the above steps according to the dirtiness of the lens of the camera 3, thereby completing the cleaning of the lens of the camera 3.

[0040] A heating command is sent through the remote control device, and after being received by the wireless communication module 104, it is sent to the main controller 100. The main controller 100 drives the heating device 10 to heat the air in the heating device to 50°C. The main controller 100 drives the motor driving circuit 101, and the motor driving circuit 101 drives the air pump 11 to extract the hot air in the heating device 10, and transports it to the inner cavity of the first ring 4 through the second conduit 15. The hot air is ejected from the upper end of the first ring 4 toward the mirror surface of the camera 3, thereby defogging the lens of the camera 3 and ensuring that the camera 3 can normally capture the image of the power line equipment.

[0041] When a large number of water drops fall in front of the lens of the camera 3, the brush head of the brush handle 19 can be used to wipe the lens of the camera 3 first, and then the heating device 10 is started to dry the lens of the camera 3, which saves battery power loss and improves the endurance of the monitoring device.

[0042] The main controller 100 drives the motor driving circuit 101 to control the motor 102 to rotate forward, driving the belt of the conveyor belt 9 to rotate downward. When the conveyor belt 9 drives the brush handle 19 to move downward to the top of the washboard 22, the main controller 100 detects that the infrared radiation of the infrared radiating tube 104 is blocked by the brush handle 19. The main controller 100 controls the motor driving circuit 101 to stop the motor 102, so that the brush handle 19 stops above the washboard 22, and the brush head of the brush handle 19 abuts against the washboard 22. The main controller 100 drives the motor driving circuit 101 to control the first electric telescopic rod 23 to perform timed telescopic movement, thereby driving the washboard 22 to clean the brush head of the brush handle 19. After cleaning, the main controller 100 sends a control signal to the motor driving circuit 101 again, and the motor driving circuit 101 drives the motor 102 to reverse, driving the brush handle 19 to return to the top of the spray plate 7, so that the brush head of the brush handle 19 remains clean and can be used multiple times.

These descriptions are not intended to limit the utility model to the precise form disclosed, and it is clear that many changes and variations can be made based on the above teachings.
