Description

Technical Field

[0001] This invention relates to the field of power system technology, and more specifically, to a voltage testing drone for power distribution lines. Background Technology

[0002] Power line drones are intelligent devices specifically designed for power line inspection. They consist of a power system, flight control system, mission equipment, and communication modules. Through autonomous flight and multi-sensor collaboration, they achieve efficient and safe monitoring of line conditions and identification of potential hazards. The drones are equipped with voltage detectors, which detect whether an object is charged by the physical phenomenon of like charges repelling each other. When a charged object comes into contact with the metal ball at the top of the voltage detector, the charge is transferred to the foils through the metal rod, causing the two metal foils to repel each other due to the same charge. The angle of opening is positively correlated with the amount of charge.

[0003] Currently, existing voltage testing drones have the following drawbacks in use:

[0004] Firstly, the voltage testing drone is usually launched manually and flies to the power distribution line waiting to be tested, so that the end of the voltage detector installed on the drone makes contact with the power distribution line to achieve the purpose of voltage testing. However, if the operator is not skilled enough or the weather is windy, the drone will shake and become unstable, so the end of the voltage detector cannot be accurately aligned with the power distribution line, thus failing to achieve the purpose of voltage testing and reducing the efficiency of voltage testing.

[0005] Secondly, in some areas with severe weather (such as frigid regions), due to the low temperature, the surface of power distribution lines may be covered with ice or frost. When staff use voltage testing drones to test the power distribution lines, the ice or frost layer can prevent the tip of the voltage tester from making contact with the surface of the power distribution lines to achieve the purpose of voltage testing, resulting in poor voltage testing results. Even if the power distribution lines are de-iced and de-frosted manually beforehand, the de-icing and de-frosting process is cumbersome, further reducing the efficiency of voltage testing.

[0006] Thirdly, sometimes the power distribution line is not high, but the surrounding trees are tall, causing the power distribution line to come into contact with the branches and leaves of the tall trees. This not only makes it difficult for manual operation of the drone to perform voltage testing on the power distribution line, but may also cause electric shock damage to the drone due to the presence of branches. In view of this, we propose a voltage testing drone for power distribution lines. Summary of the Invention

[0007] The purpose of this invention is to provide a voltage testing drone for power distribution lines. It uses axial force to drive the adjustment mechanism to rotate, switching it to a clamping mode to insulate and clamp the power distribution line, making the structure more stable when the drone body is suspended below the power distribution line. The axial force also drives the adjustment mechanism to rotate, switching it to a frost removal mode to gradually melt the frost on the surface of the power distribution line, achieving de-icing and defrosting. Furthermore, the axial force drives the adjustment mechanism to rotate, switching it to a shearing mode to cut horizontal branches near the power distribution line. In conjunction with the operation of the first drive mechanism, it moves the two output ends horizontally to cut vertical branches.

[0008] To achieve the above objectives, a power distribution line voltage testing drone is provided, comprising a drone body, a mounting frame fixedly mounted on the top outer ring of the drone body, a voltage testing device for testing power distribution lines being mounted at the top center of the mounting frame, a first drive mechanism for providing horizontal lateral driving force being mounted on the top outer ring of the mounting frame, a second drive mechanism for providing vertical longitudinal driving force being symmetrically mounted on the two output ends of the first drive mechanism, two third drive mechanisms for providing horizontal longitudinal driving force being symmetrically mounted on the output ends of the two second drive mechanisms, and an adjustment mechanism being provided on the output ends of the four third drive mechanisms. The adjustment mechanism is equipped with an axial rotation force, which is used to adjust and switch the clamping, de-icing, and shearing modes of the adjustment mechanism, respectively clamping, de-icing and defrosting the power distribution line, and shearing horizontal branches. The adjustment mechanism cooperates with the first drive mechanism to shear horizontal branches.

[0009] As a further improvement to this technical solution, each of the four adjustment mechanisms includes a rotating block, and each of the four rotating blocks has a first arc-shaped groove on the side near the voltage testing device. Each of the four first arc-shaped grooves is fixedly provided with an arc-shaped insulating pad. When two adjacent arc-shaped insulating pads are arranged opposite each other, the adjustment mechanism forms a clamping shape.

[0010] As a further improvement to this technical solution, each of the four rotating blocks has a second arc-shaped groove on the side away from the voltage testing device. The second arc-shaped groove has two sets of first mounting grooves, and heating elements are fixedly installed in both sets of first mounting grooves.

[0011] As a further improvement to this technical solution, a second mounting slot is provided between every two sets of the first mounting slots, and each of the four sets of the second mounting slots is rotatably equipped with an insulating roller. When two adjacent sets of the insulating rollers are arranged opposite each other, the adjustment mechanism forms a defrosting and de-icing mode.

[0012] As a further improvement to this technical solution, shear blocks are symmetrically fixed at both ends of the four rotating blocks. When two adjacent shear blocks are arranged opposite each other, the adjustment mechanism forms a shearing shape.

[0013] As a further improvement to this technical solution, each of the four adjustment mechanisms also includes a device box. The four device boxes are slidably mounted on the two second drive mechanisms. A motor is fixedly installed on the inner wall of each of the four device boxes. A connecting block is fixedly installed through the output end of each of the four motors through the four device boxes. The top of each of the four connecting blocks is fixedly connected to the bottom of the four rotating blocks.

[0014] As a further improvement to this technical solution, each of the four third drive mechanisms includes a fixing block. The four fixing blocks are respectively fixedly mounted on the two second drive mechanisms. Each of the four fixing blocks has a first electric telescopic rod fixedly mounted on the side of the device box. The output ends of the four first electric telescopic rods are fixedly mounted on the device box.

[0015] As a further improvement to this technical solution, each of the two second drive mechanisms includes a set of second electric telescopic rods, and a lifting plate is fixedly installed at the output end of each of the two sets of second electric telescopic rods. The bottom ends of the four equipment boxes are respectively slidably engaged with the top center of the two lifting plates, and the bottom ends of the two adjacent fixed blocks are respectively fixedly connected to the top ends of the two lifting plates.

[0016] As a further improvement to this technical solution, the first driving mechanism includes an electric slide rail, the bottom of which is fixedly mounted on the mounting frame, and mounting plates are fixedly mounted on both output ends of the electric slide rail. The bottom ends of the two sets of second electric telescopic rods are respectively fixedly connected to the tops of the two mounting plates.

[0017] As a further improvement to this technical solution, the first driving mechanism also includes a guide rail, the bottom of which is fixedly disposed on the top outer ring of the mounting bracket, and two movable blocks are slidably disposed on the surface of the guide rail, the tops of which are respectively fixedly engaged with the bottoms of the two mounting plates.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. In this power distribution line voltage testing drone, the axial force within the adjustment mechanism drives the adjustment mechanism to rotate, causing it to switch to a clamping mode. In this clamping mode, the adjustment mechanism rises with the drone body to the periphery of the power distribution line. Then, in conjunction with the vertical driving force of the second drive mechanism and the horizontal driving force of the third drive mechanism, the adjustment mechanism operates to perform insulation clamping of the power distribution line. This makes the structure more stable when the drone body is suspended below the power distribution line, significantly reducing the swaying amplitude caused by unskilled manual operation or windy weather. It also facilitates accurate contact between the end of the voltage testing device and the surface of the power distribution line to complete the voltage testing operation, thus improving voltage testing efficiency.

[0020] 2. In this power distribution line voltage testing drone, the axial force drives the adjustment mechanism to rotate, switching it to the frost removal state. In this state, the adjustment mechanism, along with the drone body, ascends to the periphery of the power distribution line. Then, in conjunction with the vertical driving force of the second drive mechanism and the horizontal driving force of the third drive mechanism, the adjustment mechanism operates to insulate and clamp the power distribution line, generating heat. This heat, combined with the horizontal movement of the drone body, causes the adjustment mechanism to slide along the surface of the power distribution line, gradually melting the frost and achieving the purpose of de-icing and defrosting. Then, it switches back to the clamping state, repeating the clamping operation of the adjustment mechanism and the voltage testing operation of the voltage testing device. This further improves the voltage testing efficiency of the drone.

[0021] 3. In this power distribution line voltage testing drone, the axial force drives the adjustment mechanism to rotate, switching it to a shearing state. As the drone takes off, the vertical driving force of the second drive mechanism and the horizontal driving force of the third drive mechanism drive the adjacent adjustment mechanisms closer together, cutting off horizontal branches near the power distribution line. Alternatively, the adjustment mechanisms can be put into a clamping or de-icing / defrosting state. The operation of the first drive mechanism drives the two output ends to move horizontally, causing the four adjustment mechanisms to move closer together and cut off horizontal branches. This facilitates voltage testing operations for staff, avoids electric shock damage to the drone, and improves voltage testing safety. Attached Figure Description

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] When testing power distribution lines, the drone may shake and become unstable due to insufficient operator skills or windy weather. Ice or frost may prevent the detector tip from making contact with the power distribution line surface for testing. Furthermore, power distribution lines near branches and leaves of tall trees make it difficult to operate the drone manually for testing.

[0037] Therefore, this invention provides a voltage testing drone for power distribution lines. Please refer to [link / reference]. Figures 1-11 It includes a drone body 1, which comprises a flight system, a camera system, and a communication module. The flight system drives the drone body 1 to fly, and the camera system captures images of the power distribution line conditions, transmitting these images to the operator's control terminal via the communication module. A mounting frame 2 is fixedly mounted on the top outer ring of the drone body 1. A voltage testing device 3 for testing the power distribution line is located at the center of the top of the mounting frame 2. The voltage testing device 3 includes a pole and a voltage detector. The pole moves the voltage detector vertically upwards towards the power distribution line, bringing its end into contact with the line to complete the voltage testing operation. The voltage detector detects whether an object is charged by the physical phenomenon of like charges repelling each other. When a charged object contacts the metal ball at the top of the voltage detector, the charge is transferred through the metal rod to the foil, causing the two foils to repel each other due to the same charge. The angle of the repulsion is positively correlated with the amount of charge. Figure 9 As shown, the top outer ring of the mounting bracket 2 is provided with a first drive mechanism 4 for providing horizontal driving force. Two second drive mechanisms 5 are symmetrically arranged at the two output ends of the first drive mechanism 4 for providing vertical driving force. Two third drive mechanisms 6 are symmetrically arranged at the output ends of each of the two second drive mechanisms 5 for providing horizontal driving force. Each of the four third drive mechanisms 6 has an adjustment mechanism 7 at its output end. The adjustment mechanism 7 has an axial rotational force, which is used to adjust and switch the clamping, de-icing, and shearing modes of the adjustment mechanism 7, respectively clamping, de-icing / defrosting the power distribution line, and shearing horizontal branches. The adjustment mechanism 7 also works in conjunction with the first drive mechanism 4 to shear horizontal branches. Specifically:

[0038] The present invention is as follows Figure 1-3 As shown, considering that when testing power distribution lines, if the operator's operating skills are not proficient or the weather is windy, the drone body 1 may shake continuously and become unstable, causing the end of the voltage testing device 3 to be unable to accurately align with the power distribution line, thus failing to achieve the purpose of voltage testing and reducing the efficiency of voltage testing, therefore, if Figure 1-2As shown, the axial force inside the adjustment mechanism 7 drives the adjustment mechanism 7 to rotate, causing the adjustment mechanism 7 to switch to the clamping mode. In the clamping mode, the adjustment mechanism 7 rises with the drone body 1 to the side of the power distribution line. Then, in conjunction with the vertical driving force of the second drive mechanism 5 and the horizontal driving force of the third drive mechanism 6, the adjustment mechanism 7 is driven to operate to perform insulation clamping on the power distribution line. This makes the structure more stable when the drone body 1 is suspended below the power distribution line, significantly reducing the swaying amplitude of the drone body 1 caused by the lack of skilled operation or the influence of windy weather. It is also more conducive to the accurate contact between the end of the voltage testing device 3 and the surface of the power distribution line to complete the voltage testing operation, which helps to improve the voltage testing efficiency.

[0039] Furthermore, in some areas with severe weather, such as frigid regions, the surface of power distribution lines may be covered with ice or frost due to the low temperature. When workers use the drone body 1 and voltage testing device 3 to test the power distribution lines, the ice or frost layer prevents the end of the voltage testing device 3 from making contact with the surface of the power distribution lines to achieve the purpose of voltage testing, resulting in poor testing effectiveness. Even if the power distribution lines are de-iced or defrosted manually beforehand, the de-icing and defrosting process is cumbersome, further reducing the efficiency of voltage testing. Therefore, if... Figure 2 As shown, the axial force drives the adjustment mechanism 7 to rotate, switching the adjustment mechanism 7 to the frost removal state. In the frost removal state, the adjustment mechanism 7 rises with the drone body 1 to the periphery of the power distribution line. Then, with the vertical driving force of the second drive mechanism 5 and the horizontal driving force of the third drive mechanism 6, the adjustment mechanism 7 is driven to operate to insulate and clamp the power distribution line, and generates heat. With the horizontal movement of the drone body 1, the adjustment mechanism 7 slides along the surface of the power distribution line, so that the frost on the surface of the power distribution line gradually melts, achieving the purpose of de-icing and defrosting. Then, it switches back to the clamping state of the adjustment mechanism 7, and repeats the clamping operation of the adjustment mechanism 7 and the voltage testing operation of the voltage testing device 3, which helps to further improve the voltage testing efficiency of the drone.

[0040] Furthermore, sometimes the power distribution lines are not very high, while the surrounding trees are quite tall, causing the power distribution lines to come into contact with the branches and leaves of the taller trees. This not only makes it difficult for the drone to be manually operated to perform voltage testing on the nearby power distribution lines, but also may cause the drone to be damaged by electric shock due to the presence of branches. Therefore, if... Figure 2As shown, the axial force drives the adjustment mechanism 7 to rotate, switching it to a shearing state. As the drone body 1 takes off, the vertical driving force of the second drive mechanism 5 and the horizontal driving force of the third drive mechanism 6 drive the adjacent adjustment mechanism 7 to move closer, cutting off horizontal branches near the power distribution line. Alternatively, the adjustment mechanism 7 can be put into a clamping or de-icing / defrosting state. In conjunction with the operation of the first drive mechanism 4, the two output ends move horizontally, causing the four adjustment mechanisms 7 to move closer to each other, cutting off horizontal branches. This facilitates electrical testing by staff, prevents electric shock damage to the drone body 1, and improves electrical testing safety.

[0041] Based on the above, the specific structure will be disclosed in detail:

[0042] To achieve the goal of clamping the power distribution line under the drive of the second drive mechanism 5 and the third drive mechanism 6 when the adjustment mechanism 7 is in the clamping state, thereby stabilizing the suspended UAV body 1 and facilitating the orderly conduct of the voltage testing process, it is necessary to disclose the specific structure of the adjustment mechanism 7. Therefore, as... Figure 3 and Figure 11 As shown, each of the four adjustment mechanisms 7 includes a rotating block 71. Each of the four rotating blocks 71 has a first arc-shaped groove on the side closest to the voltage testing device 3. An arc-shaped insulating pad 72 is fixedly installed in each of the four first arc-shaped grooves. The arc-shaped insulating pad 72 is made of insulating material to prevent current from the power distribution line from damaging the UAV body 1. When two adjacent arc-shaped insulating pads 72 are positioned opposite each other, the adjustment mechanism 7 forms a clamping configuration. The third drive mechanism 6 drives the adjustment mechanism 7 to move horizontally and longitudinally, causing adjacent rotating blocks 71 to move closer or further apart. When two rotating blocks 71 move closer together, they can clamp the power distribution line waiting to be tested. Figure 6 As shown, the UAV body 1 is stably suspended in a floating state, which facilitates the orderly conduct of the electrical testing process.

[0043] To enable the regulating mechanism 7 to move to the periphery of the power distribution line under the drive of the second drive mechanism 5 and the third drive mechanism 6 when it is in the de-icing / defrosting mode, and to perform de-icing / defrosting operations on the power distribution line, it is necessary to further disclose the specific structure of the regulating mechanism 7. Therefore, as... Figure 3As shown, a second arc-shaped groove is provided on the side of each of the four rotating blocks 71 away from the voltage testing device 3. The second arc-shaped groove has two sets of first mounting grooves, and heating elements 73 are fixedly installed in both sets of first mounting grooves. The heating elements 73 include structures such as conductors and wires. Utilizing the resistance heating effect, when current passes through the conductor via the wires, electrical energy is converted into heat energy, thereby achieving heating. The heating elements 73 generate heat themselves to heat the rotating blocks 71 and the periphery of the power distribution line close to the heating elements 73. This temperature is lower than the temperature that the surface of the power distribution line can withstand, so it will not affect the normal operation of the power distribution line, thus melting frost and preventing frost from blocking the end of the voltage testing device 3 from contacting the surface of the power distribution line, thereby improving the voltage testing efficiency.

[0044] To achieve the following: when the adjustment mechanism 7 is in the de-icing / defrosting mode, the rotating block 71 and the heating element 73 move along the power distribution line as the UAV body 1 moves horizontally, it is necessary to further disclose the specific structure of the adjustment mechanism 7. Therefore, as... Figure 3 and Figure 11 As shown, a second mounting slot is provided between every two sets of first mounting slots. Each of the four sets of second mounting slots is equipped with an insulating roller 74, made of insulating material to prevent current from the power distribution line from damaging the UAV body 1. When adjacent sets of insulating rollers 74 are positioned opposite each other, the adjustment mechanism 7 forms a de-icing / defrosting mode. Driven by the second drive mechanism 5 and the third drive mechanism 6, the adjacent rotating blocks 71 in the de-icing / defrosting mode move relative to each other, causing the insulating rollers 74 to contact the surface of the power distribution line. Figure 7 As shown, the horizontal movement of the UAV body 1 causes the rotating block 71 to move horizontally, as... Figure 10 As shown, the insulating roller 74 rolls on the surface of the power distribution line, reducing the friction between the rotating block 71 and the power distribution line, preventing the power distribution line from blocking the movement of the rotating block 71 and the heating element 73, and improving the efficiency of frost removal in the defrosting mode.

[0045] To achieve the effect that when the adjusting mechanism 7 is in the shearing state, under the drive of the second driving mechanism 5 and the third driving mechanism 6, the two adjacent rotating blocks 71 move closer to each other to prune the horizontal branches and prevent them from interfering with the voltage testing process, it is necessary to further disclose the specific structure of the adjusting mechanism 7. Therefore, as... Figure 4 and Figure 11 As shown, shearing blocks 75 are symmetrically fixed at both ends of the four rotating blocks 71. When two adjacent shearing blocks 75 are arranged opposite each other, the adjusting mechanism 7 forms a shearing shape. This is achieved by aligning two adjacent shearing blocks 75. Figure 8As shown, driven by the second drive mechanism 5 and the third drive mechanism 6, two adjacent shearing blocks 75 move closer to each other and cut off the branches between the two shearing blocks 75, that is, the branches in a horizontal and transverse state, to prevent the branches in a horizontal and transverse state from affecting the normal operation of the voltage detection process.

[0046] To enable the adjustment mechanism 7 to switch between clamping, de-icing / defrosting, and shearing modes, it is necessary to explain the source of the axial force within the adjustment mechanism 7. This requires further disclosure of the specific structure of the adjustment mechanism 7, such as... Figure 4 As shown, each of the four adjustment mechanisms 7 also includes an equipment box 76. The four equipment boxes 76 are slidably mounted on the two second drive mechanisms 5. A motor 77 is fixedly installed on the inner wall of each of the four equipment boxes 76. The output ends of the four motors 77 are respectively fixedly mounted with connecting blocks 78 through the four equipment boxes 76. The tops of the four connecting blocks 78 are respectively fixedly connected to the bottoms of the four rotating blocks 71. The axial rotational force generated by the operation of the motors 77 causes the motors 77 to rotate forward or backward, driving the connecting blocks 78 and rotating blocks 71 to rotate. This causes the two adjacent arc-shaped insulating pads 72, the two sets of insulating rollers 74 and the two shearing blocks 75 to be arranged opposite each other, thereby switching the clamping, de-icing, defrosting and shearing modes of the adjustment mechanism 7, improving the efficiency and safety of voltage detection.

[0047] To enable the third drive mechanism 6 to provide horizontal and longitudinal driving force to move adjacent rotating blocks 71 closer or further apart, the specific structure of the third drive mechanism 6 needs to be disclosed. Therefore, as... Figure 3 As shown, each of the four third drive mechanisms 6 includes a fixed block 61. The four fixed blocks 61 are respectively fixedly mounted on the two second drive mechanisms 5. Each of the four fixed blocks 61 has a first electric telescopic rod 62 fixedly mounted on the side of the equipment box 76. The output ends of the four first electric telescopic rods 62 are fixedly mounted on the equipment box 76. By extending the first electric telescopic rod 62 itself, it drives the connected equipment box 76 to move along the horizontal longitudinal direction, so that the two adjacent equipment boxes 76 move closer to each other. This, in turn, drives the two adjacent rotating blocks 71 in the clamping, de-icing, and shearing modes to move closer to each other, respectively clamping, de-icing, and shearing the power distribution line and cutting the horizontal branches.

[0048] In order for the second drive mechanism 5 to provide vertical driving force to move the first electric telescopic rod 62 and rotating block 71 along the vertical direction, so as to cooperate with the first electric telescopic rod 62 and rotating block 71 to perform operations such as clamping, de-icing, defrosting, and cutting horizontal branches on the power distribution lines, the specific structure of the second drive mechanism 5 is required. Therefore, such as Figure 3As shown, each of the two second drive mechanisms 5 includes a set of second electric telescopic rods 51. A lifting plate 52 is fixedly installed at the output end of each of the two sets of second electric telescopic rods 51. The bottom ends of the four equipment boxes 76 are respectively slidably engaged with the top center of the two lifting plates 52. The bottom ends of the two adjacent fixed blocks 61 are respectively fixedly connected to the top ends of the two lifting plates 52. By extending or shortening the second electric telescopic rods 51, the first electric telescopic rod 62 and the rotating block 71 are driven to move in the vertical direction to cooperate with the first electric telescopic rod 62 and the rotating block 71 to perform operations such as clamping, de-icing, defrosting, and cutting horizontal branches on the power distribution lines, thereby improving the power testing efficiency of the UAV.

[0049] To enable the first drive mechanism 4 to move in coordination with the shearing block 75 to cut off branches in the horizontal longitudinal direction, the specific structure of the first drive mechanism 4 needs to be disclosed. Therefore, as... Figure 3 As shown, the first drive mechanism 4 includes an electric slide rail 41. The slide rail 41 includes a motor, a bidirectional lead screw, and two sliders. The rotation of the motor drives the bidirectional lead screw to rotate, which in turn drives the two sliders to move closer or further apart. The bottom of the electric slide rail 41 is fixedly mounted on the mounting bracket 2. Mounting plates 42 are fixedly mounted on both output ends of the electric slide rail 41. The bottom ends of two sets of second electric telescopic rods 51 are fixedly connected to the tops of the two mounting plates 42 respectively. The rotation of the electric slide rail 41 drives the two mounting plates 42 to move closer or further apart. Figure 5 As shown, the two pairs of rotating blocks 71 move closer and further apart. When the two pairs of rotating blocks 71 move closer to each other, the branches in the horizontal longitudinal direction can be pruned, thus improving the efficiency of voltage detection.

[0050] To enhance structural stability when the electric slide rail 41 rotates and drives the mounting plates 42 to move away from or towards each other, it is necessary to further disclose the specific structure of the first drive mechanism 4. Therefore, as... Figure 3 As shown, the first drive mechanism 4 also includes a guide rail 43. The bottom of the guide rail 43 is fixedly mounted on the top outer ring of the mounting bracket 2. Two moving blocks 44 are slidably mounted on the surface of the guide rail 43. The tops of the two moving blocks 44 are fixedly engaged with the bottoms of the two mounting plates 42 respectively. The two mounting plates 42 are driven to move closer or further apart in the horizontal direction by the electric slide rail 41, which drives the moving blocks 44 to slide on the guide rail 43, making the structural stability of the mounting plates 42 stronger when moving.

[0051] In summary, the overall working principle of this invention is as follows:

[0052] When the power testing drone is needed to test the power distribution line, the staff controls the drone body 1 to move under the power distribution line. When it is necessary to clamp the power distribution line to reduce the shaking amplitude of the drone body 1 and other structures, the rotating block 71 is in the clamping state. The second electric telescopic rod 51 is activated to extend it, which drives the lifting plate 52, the first electric telescopic rod 62, the equipment box 76 and the rotating block 71 to move downward or upward, so that the four arc-shaped insulating pads 72 are close to the power distribution line. Then, the first electric telescopic rod 62 is extended to drive the rotating block 71 and the arc-shaped insulating pads 72 to move and clamp them. After clamping, the power testing device 3 is brought close to the power distribution line to make contact with it for power testing.

[0053] When it is necessary to remove frost from the surface of the power distribution line, the motor 77 is started to rotate at a set angle, which drives the connecting block 78 and the rotating block 71 to rotate at a set angle, so that the two adjacent sets of insulating rollers 74 are set opposite each other. Then, the drone body 1 is used to move the rotating block 71 and other structures to the periphery of the power distribution line. Then, the first electric telescopic rod 62 is extended to drive the rotating block 71 and the insulating rollers 74 to approach the power distribution line, so that the insulating rollers 74 contact the power distribution line. The heating element 73 is activated to generate heat. Then, the drone body 1 is controlled to fly horizontally, driving the insulating rollers 74 to roll and move along the surface of the power distribution line to perform de-icing and de-frosting operations on the surface of the power distribution line. After the de-icing and de-frosting operations are completed, the above clamping process is repeated to continue the voltage testing operation.

[0054] When it is necessary to prune horizontal branches near the power distribution line, the drone body 1 moves the rotating block 71 and other structures to the periphery of the horizontal branches of the power distribution line, causing the connecting block 78 and the rotating block 71 to rotate at a set angle, so that the adjacent shearing blocks 75 are positioned opposite each other. Then, the first electric telescopic rod 62 extends to move the rotating block 71 and the shearing block 75 to prune the branches. When it is necessary to prune horizontal branches near the power distribution line, the drone body 1 moves the rotating block 71 and other structures to the periphery of the horizontal branches of the power distribution line, so that the rotating block 71 is in a clamping or de-icing / defrosting state. The electric slide rail 41 is activated to move the two pairs of shearing blocks 75 closer to each other to prune the branches.
