[0002] The application of artificial intelligence technology is particularly important in the inspection of power transmission lines in the power industry. With the rapid development of my country's economy, the demand for energy is increasing. Ultra-high voltage and large-capacity transmission lines have been greatly expanded. Transmission line corridors need to pass through various complex geographical environments, even areas where geological disasters are frequent. How to solve the daily inspection of transmission lines and improve detection accuracy and efficiency has become a major problem.

[0003] To this end, a self-cruising drone for transmission line detection is derived by combining drone technology with the adaptive ground wire inspection technology of a single-line laser radar. Through the laser radar equipment, combined with binocular vision recognition technology, and the deployment of deep convolutional neural network algorithms, it is possible to realize transmission line inspection based on adaptive ground wire inspection, spacer inspection, tree-line conflict inspection, conductor foreign object detection, and sag / phase line distance measurement.

[0004] However, during the implementation process, the self-cruising UAV has weak adaptability and cannot cope with unexpected events. When there is strong signal interference or in rainy and snowy environments, the circuit or mechanical parts of the self-cruising UAV may malfunction. Once the self-cruising UAV fails, it will accidentally fall, causing the self-cruising UAV to free fall, resulting in economic and property losses, threatening personal safety and other accidents.

[0038] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. The utility model is further described in combination with the drawings and embodiments:

[0039] Embodiment 1:

[0040] Refer to the attached Figure 1 -Attached Figure 5 As shown, a self-cruising drone for power transmission line detection includes a frame 1, a drone body 2 arranged on the frame 1, a single-line laser radar structure 3 and a visual recognition structure 4 arranged on the drone body 2, wherein the single-line laser radar structure 3 and the visual recognition structure 4 are prior arts, and this application does not elaborate on them, and the real-time detection, tracking and photo shooting of the power transmission line are achieved by this means; in addition, it also includes a buffer structure 5, which is arranged on the top of the drone body 2;

[0041] In the specific implementation process of this embodiment, when the unmanned aerial vehicle 2 is in a normal flight state, the buffer structure 5 does not work. At this time, the line laser radar structure and the visual recognition structure 4 realize the real-time detection and tracking of the transmission line and the photo shooting operation. Figure 2 When the flight state of the unmanned aerial vehicle 2 is abnormal, that is, the detection component 53 detects that the falling acceleration of the unmanned aerial vehicle 2 reaches the set value, the automatic door 52 opens. Figure 1 As shown, the parachute 56 pops out and opens. The opened parachute 56 provides a buffer for the drone body 2, causing the drone body 2 to fall slowly, thereby reducing the occurrence of accidents.

[0042] For details, please refer to the attached Figure 3 As shown, the buffer structure 5 includes an outer shell 51, an automatic door 52, a detection component 53, a mounting tube 54, an elastic component 55 and a parachute 56; the outer shell 51 is open at the top and is installed with the automatic door 52, wherein the automatic door 52 is a flip door or a sliding door commonly used in the prior art, and this application does not limit this; a detection component 53 is arranged in the outer shell 51, the detection component 53 is electrically connected to the automatic door 52 and a mounting tube 54 is arranged on one side, the mounting tube 54 is open at the top and is connected with a parachute 56 via the elastic component 55, so that the detection component 53 detects that the falling acceleration of the unmanned aerial vehicle body 2 reaches a set value, the automatic door 52 is opened, and the parachute 56 pops out.

[0043] In the above solution, the structure of the detection component 53 is specifically as follows:

[0044] Refer to the attached Figure 3 As shown, the detection component 53 includes a controller 531 and an acceleration sensor 532; the controller 531 and the acceleration sensor 532 are both arranged inside the outer shell 51, and the controller 531 is electrically connected to the acceleration sensor 532 and the automatic door 52; in the implementation process of the scheme, when the acceleration sensor 532 detects that the acceleration of the drone during the falling process reaches the set value, that is, the flight condition of the drone is abnormal at this time, and there is a risk of falling, the signal is immediately fed back to the controller 531, and the controller 531 controls the automatic door 52 to open;

[0045] Among them, considering the threat to personnel safety during the falling process, the detection component 53 also includes a buzzer 533; the buzzer 533 is electrically connected to the controller 531, and when the automatic door 52 is opened, the buzzer 533 will sound an alarm; during the implementation of the solution, the buzzer 533 will sound an alarm, thereby giving a warning to the personnel below, making them alert and reducing the occurrence of accidents.

[0046] In the above solution, the structure of the elastic component 55 is specifically as follows:

[0047] Refer to the attached Figure 4 As shown, the elastic component 55 includes a telescopic cylinder 551, a lifting plate 552, a spring 553 and a mounting plate 554; the telescopic cylinder 551 is vertically arranged in the mounting tube 54 and is electrically connected to the controller 531, the telescopic end of the telescopic cylinder 551 is connected to the lifting plate 552, the lifting plate 552 is slidably arranged in the mounting tube 54, and the lifting plate 552 is connected to the mounting plate 554 through the spring 553, the mounting plate 554 is slidably arranged in the mounting tube 54 and its surface is connected to the rope end of the parachute 56;

[0048] During the implementation of the scheme, the telescopic end of the telescopic cylinder 551 is in an extended state in the initial state. During this process, the spring 553 is in a compressed state due to the limit of the automatic door 52. When the automatic door 52 is opened, the spring 553 returns to its original length and the parachute 56 is ejected. Subsequently, the telescopic end of the telescopic cylinder 551 is shortened. Figure 5 As shown, in this state, a space is formed between the mounting plate 554 and the upper part of the mounting tube 54 for storing the used parachute 56. After the used parachute 56 is refolded and placed in the space, the automatic door 52 is closed, and then the telescopic end of the telescopic cylinder 551 is extended, and the spring 553 is in a compressed state due to the limit of the automatic door 52 until the opening mechanism of the automatic door 52 is triggered again.

[0049] Among them, considering the ventilation and heat dissipation of the buffer structure 5, for this purpose, refer to the attached Figure 3 As shown, a plurality of flow holes 511 are opened on the side wall of the outer shell 51, and the plurality of flow holes 511 are arranged in a shutter structure to reduce the entry of rainwater.

Therefore, considering the disassembly and assembly operations of the buoyancy rod 6, the buoyancy rod 6 is installed at the bottom of the frame 1 through a strap.

[0052] Embodiment 3:

[0053] The difference from Example 1 is that, considering the risk of insufficient voltage of the battery of the drone body 2 when used in a low temperature environment, Figure 7 As shown, a self-cruising drone for power transmission line detection also includes a constant temperature structure 7, which is arranged on one side of the battery of the drone body 2 to heat or keep the battery of the drone body 2 warm; specifically, the constant temperature structure 7 includes a temperature sensor 71 and a heating plate 72; the temperature sensor 71 is electrically connected to the heating plate 72, so that when the temperature sensor 71 detects that the battery of the drone body 2 is lower than the set value, the heating plate 72 converts electrical energy into thermal energy to start heating and raise the temperature to 20-30°C.
