The two hook portions 232 and the third conductive sheets 233 are respectively connected to the positive and negative poles of the battery; the monitor 24 is connected to the bottom of the fuselage 21.

[0020] The hanging mobile rack 3 includes a connecting seat 31 and a charging hanging seat 32. The connecting seat 31 has two connecting holes 311. The integrated wire 4 passes through the connecting hole 311. The connecting hole 311 has a first conductive sheet 31121. The first conductive sheets 31121 of the two connecting holes 311 are respectively in contact with the neutral line 43 and the live line 44. Specifically, the connecting hole 311 includes a core 3111 and an ear 3112.

[0021] Pressure sensing components are provided at the upper and lower ends of the inner wall of the connecting hole 311 near the opening, and the pressure sensing components include a pressure wheel 313 and a pressure sensor. The lower end of the pressure wheel 313 extends into the connecting hole 311, and the pressure sensor is used to detect the pressure of the pressure wheel 313.

Specifically, a signal receiving system is provided in the connecting seat 31. The eight pressure sensors in the two connecting holes 311 generate signals to the drone body 2 in real time during the movement of the connecting seat 31, so that the drone body 2 adjusts the flipping direction and output power of the multiple flip-type flight blades 22 according to the signals, thereby ensuring that the connecting hole 311 will not have stress concentration to compress the integrated wire 4, reduce the loss of the integrated wire 4, and increase the service life of the integrated wire 4.

Two limit blocks 312 are formed on the side walls of the connecting mount 31. The limit blocks 312 are located on both sides of the connecting plates 321. There is a gap between the limit blocks 312 and the connecting plates 321. The connecting plates 321 are provided to allow the charging mount 32 to have a certain swing space under the action of wind, reduce the shaking of the connecting mount 31 and improve the stability of movement. The function of providing the limit blocks 312 is to prevent the charging mount 32 from swinging too far and enable the drone body 2 to push the hanging mobile frame 3 to move.

[0024] Working principle: When the drone body 2 is inspecting and reaches the position of one of the elevated towers 1, the hook 23 on the drone body 2 is hung on the charging notch 322 of the charging mount 32 in the hanging mobile frame 3. At this time, the third conductive sheet 233 of the hook 232 is in contact with the second conductive sheet 3221, so that the battery of the drone body 2 remains fully charged. The drone body 2 drives the second rotating ring 223 and the fan blade 224 to turn 90 degrees through the first rotating ring 222, or the second rotating ring 223 turns 90 degrees, so that the fan blade 224 is perpendicular to the horizontal plane, and the fan blade 224 starts to operate. Driven by the fan blade 224, the drone The drone body 2 and the hanging mobile frame 3 move along the integrated wire 4 toward the next elevated tower 1, and can stop at any time during the movement. The drone body 2 separates from the hanging mobile frame 3 for inspection, and then returns to the hanging mobile frame 3 to continue moving. When arriving at another elevated tower 1, the drone body 2 separates from the hanging mobile frame 3 and flies to the next group of elevated towers 1 to repeat the above actions until the inspection is completed. Through the above settings, a single drone body 2 can inspect the entire forest, and there is no need to manually go to a fixed position to release the drone body 2 due to insufficient power. It is more intelligent and saves time and effort, and greatly reduces manual labor.

[0025] A security inspection method suitable for a protected area, using an unmanned aerial vehicle security inspection device for inspection; S1. Multiple groups of elevated towers 1 are arranged in sequence, and the two elevated towers 1 in each group have a height difference. The hook 23 of the drone body 2 is hooked on the charging mount 32 on the integrated wire 4 between the elevated towers 1; the specific steps of S1 are as follows: the drone body 2 flies to one side of the hanging mobile frame 3, and by controlling the drone body 2, the two hooks 23 of the drone body 2 are respectively hung in the charging notch 322 of the charging mount 32 of the hanging mobile frame 3, so that the second conductive sheet 3221 and the third conductive sheet 233 are in contact.

[0026] S2. The drone body 2 is flipped 90 degrees through the second rotating ring 223, so that the fan blades 224 are perpendicular to the horizontal plane, and the fan blades 224 start to operate. Driven by the fan blades 224, the drone and the hanging movable frame 3 move upward or downward along the integrated wire 4; the specific steps of S2 are as follows: after the hook 23 of the unmanned body is hung on the charging mount 32, the first rotating ring 222 on the drone body 2 is flipped 90 degrees, so that the fan faces the cable 41, the fan starts to operate, and the drone body 2 pushes the hanging movable frame 3 to move.

[0027] S3. During the movement, when the value deviation between the pressure sensors of the four pressure wheels 313 in the connecting hole 311 is above 10N, it means that the connecting seat 31 is offset to squeeze the integrated wire 4, and the remaining two second rotating rings 223 arranged opposite to each other are rotated and dynamically adjusted to keep the value deviation between the pressure sensors of the four pressure wheels 313 in the connecting hole 311 within 10N until the UAV inspection is completed. The specific steps of S3 are as follows: During the movement of the connecting seat 31, the eight pressure sensors in the two connecting holes 311 send real-time signals to the UAV body 2, so that the UAV body 2 adjusts the flip direction and output power of the flip-type flight blade 22 according to the signals. That is, when the value deviation of each pressure sensor is above 10N, the UAV body 2 adjusts the flip direction and output power of the flip-type flight blade 22 according to the signals. The flip flight blades 22 are not adjusted. When the value deviation of each pressure sensor is outside 10N, the two second rotating rings 223 arranged opposite to each other are rotated and dynamically adjusted until the value deviation of the pressure sensor is within 10N. During the movement, the drone body 2 can be detached from the hanging mobile frame 3 for inspection at any time, and reset through the second rotating ring 223. The drone, with the cooperation of the first rotating ring 222 and the second rotating ring 223, detaches from the hanging mobile frame 3 for inspection. After the inspection, it returns to the position where the hanging mobile frame 3 stops to hook 23, and then continues to push the hanging mobile frame 3 to move until it reaches the next elevated tower 1, and then the drone body 2 detaches from the hanging mobile frame 3 and flies to the next group of elevated towers 1 until the inspection is completed.

[0028] Example 2 like Figure 1-Figure 6 and Figure 8 As shown, the difference between this embodiment and the first embodiment is that the guide wheel 31111 is not provided in the connection hole 311, and the number of hanging mobile racks 3 on the same integrated wire 4 is multiple, and the connection seat 31 is provided with an electromagnetic suction plate facing the two elevated towers 1, and the electromagnetic suction plate is in a closed state when the second conductive sheet 3221 is connected to the third conductive sheet 233, and is implemented by the circuit principle of the existing common push-type switch. Since the guide wheel 31111 and related structures are provided in the connection hole 311, when the drone body 2 flies away from the connection seat 31 during the movement, the friction force of the pressure wheel 313 cannot support the connection seat 31 not to move on the integrated wire 4, and it will move to the lower elevated tower 1 under the action of weight, and be adsorbed with other connection seats 31 through the electromagnetic suction plate. When the drone body 2 has finished patrolling, it will drive to the connection seat 31 of the nearest elevated tower 1 to hook 23 for charging, and then continue the patrol task.

[0029] This embodiment provides a security inspection method suitable for a protected area, using a drone security inspection device in Embodiment 2 for inspection; S1. Multiple groups of elevated towers 1 are arranged in sequence, and the two elevated towers 1 in each group have a height difference. The hook 23 of the drone body 2 is hooked on the charging mount 32 on the integrated wire 4 between the elevated towers 1; the specific steps of S1 are as follows: the drone body 2 flies to one side of the hanging mobile frame 3, and by controlling the drone body 2, the two hooks 23 of the drone body 2 are respectively hung in the charging notch 322 of the charging mount 32 of the hanging mobile frame 3, so that the second conductive sheet 3221 and the third conductive sheet 233 are in contact.

[0030] S2. The drone body 2 is flipped 90 degrees through the second rotating ring 223, so that the fan blades 224 are perpendicular to the horizontal plane, and the fan blades 224 start to operate. Driven by the fan blades 224, the drone and the hanging movable frame 3 move upward or downward along the integrated wire 4; the specific steps of S2 are as follows: after the hook 23 of the unmanned body is hung on the charging mount 32, the first rotating ring 222 on the drone body 2 is flipped 90 degrees, so that the fan faces the cable 41, the fan starts to operate, and the drone body 2 pushes the hanging movable frame 3 to move.

[0031] S3. During the movement, when the numerical deviation between the pressure sensors of the four pressure wheels 313 in the connecting hole 311 is above 10N, it means that the connecting seat 31 is offset to squeeze the integrated wire 4, and the remaining two second rotating rings 223 arranged opposite to each other are rotated and dynamically adjusted to keep the numerical deviation between the pressure sensors of the four pressure wheels 313 in the connecting hole 311 within 10N until the UAV inspection is completed. The specific steps of S3 are as follows: During the movement of the connecting seat 31, the eight pressure sensors in the two connecting holes 311 send real-time signals to the UAV body 2, so that the UAV body 2 adjusts the flipping direction and output power of the flipping flight blade 22 according to the signal, that is, when the numerical deviation of each pressure sensor is within 10N, the flipping flight blade 22 is not adjusted; when the numerical deviation of each pressure sensor is within 10 N, the two second rotating rings 223 arranged opposite to each other are rotated and dynamically adjusted until the value deviation of the pressure sensor is within 10N; during the movement, the drone body 2 can be detached from the hanging mobile frame 3 for inspection at any time, and reset through the second rotating ring 223. The drone, with the cooperation of the first rotating ring 222 and the second rotating ring 223, detaches from the hanging mobile frame 3 for inspection. After the connecting seat 31 halfway is detached from the drone body 2, it slides back to the elevated tower 1 at a lower place under the action of gravity, and other connecting seats 31 close to it are adsorbed and fixed by electromagnetic suction plates until the drone hooks 23 to the connecting seat 31 again, making its electromagnetic suction plate invalid and then moves. After the detached drone body 2 completes the inspection, it drives to the connecting seat 31 of the nearest elevated tower 1 to hook 23 for charging, and then continues the inspection mission.
