[0001] The present application relates to the technical field of line inspection, in particular to a power line inspection device based on a UAV. BACKGROUND

[0002] In overhead power line maintenance, the line needs to be inspected first to ensure the safety of the maintenance personnel. The traditional inspection method is for the operator to climb the pole and use a telescopic contact type inspection pen to inspect the line at a safe distance. After determining that the line has no voltage, the grounding wire work is carried out. With the development of economy, the daily maintenance and rescue tasks of line inspection personnel increase, and the operation tasks become more frequent. However, the traditional pole climbing inspection process has high operation risk.

[0003] Currently, some use a UAV for inspection operation, but most of them vertically install a telescopic inspection pen on the UAV, which prevents the UAV from inspecting the bottom two wires of a four-split transmission line. Some horizontally install a telescopic inspection pen, but the operator needs to first lengthen the telescopic inspection pen and then take off the UAV. This not only is troublesome to operate, but also causes the UAV to be "head-heavy and foot-light". Moreover, the existing UAV cannot ensure that the inspection pen is in close contact with the transmission line when inspecting the transmission line, which affects the inspection effect. TECHNICAL PROBLEM

[0034] Embodiment 1

[0035] Referring to FIGS. 1-4, a first embodiment of the present application provides a power line electricity testing device based on an unmanned aerial vehicle, which comprises,

[0036] The telescopic mechanism 100 comprises a UAV 101, a head frame 102 arranged on the UAV 101, a telescopic part 103 arranged on the head frame 102, a limiting part 104 arranged on the head frame 102, and a power part 105 arranged on the head frame 102.

[0037] The electricity testing mechanism 200 comprises a first sliding part 201 arranged on the telescopic part 103, an electricity testing part 202 arranged on the first sliding part 201, and a supporting part 203 arranged on the telescopic part 103.

[0038] The linkage mechanism 300 comprises a balancing part 301 arranged on the UAV 101, a second sliding part 302 arranged on the telescopic part 103, and a reset part 303 arranged on the telescopic part 103.

[0039] In use, the UAV 101 is started to approach the power transmission line. Due to the limiting of the limiting part 104, the power part 105 is started to drive the telescopic part 103 to move. The telescopic part 103 drives the first sliding part 201 to make the electricity testing part 202 extend. The UAV 101 is controlled to make the power transmission line be clamped between the electricity testing part 202 and the supporting part 203. The power part 105 is continuously started to drive the telescopic part 103 to move. The head frame 102 extrudes the second sliding part 302 to shrink. The second sliding part 302 pulls the first sliding part 201 to make the electricity testing part 202 approach the supporting part 203, so as to clamp the power transmission line between the electricity testing part 202 and the supporting part 203. At the same time, the electricity testing operation is performed on the power transmission line. The power part 105 is reversely started to open the electricity testing part 202, so as to perform the electricity testing on another power transmission line.

[0040] Embodiment 2

[0041] Referring to FIG. 1, FIG. 2, FIG. 3 and FIG. 7, the second embodiment of the present application is different from the first embodiment in that the telescopic part 103 comprises a threaded sleeve 103a arranged on the head frame 102, a threaded tube 103b arranged on the threaded sleeve 103a, and a telescopic limiting groove 103c arranged on the threaded tube 103b.

[0042] Preferably, the threaded sleeve 103a is rotationally arranged on the head frame 102. The threaded tube 103b is threadedly connected with the threaded sleeve 103a. The telescopic limiting groove 103c is arranged on the outer surface of the threaded tube 103b.

[0043] Further, the tubular design of the threaded tube 103b not only reduces the overall weight of the device and increases the endurance of the UAV 101, but also provides space for the connection between the first sliding part 201 and the second sliding part 302, so as to ensure the normal operation of the device. The telescopic limiting groove 103c is designed as a blind groove, which increases the structural strength of the threaded tube 103b, thereby increasing the service life of the device.

[0044] Further, the threaded pipe 103b is horizontally arranged. If the threaded pipe 103b is vertically arranged, the threaded pipe 103b can only perform the electricity testing operation on single or double lines, and the applicability is smaller. In the face of four split, six split, eight split transmission lines, since the transmission lines are in a polygonal three-dimensional structure, the vertically arranged electricity tester can only perform the electricity testing operation on the top transmission line. When performing the electricity testing operation on the bottom transmission line, the top transmission line will block the electricity tester, which leads to the failure of the electricity testing operation on the bottom transmission line. Moreover, since the unmanned aerial vehicle 101 needs a certain safety distance, the unmanned aerial vehicle 101 is mostly configured with an extension rod. If the extension rod is vertically arranged on the unmanned aerial vehicle 101, since the wind force in the high altitude is large, the stress area of the extension rod is large, which leads to the poor stability of the unmanned aerial vehicle 101. When performing the electricity testing operation, not only the stable electricity testing operation is failed, but also the safety accidents such as the contact of the unmanned aerial vehicle with the conductor are caused.

[0045] Further, the threaded pipe 103b is arranged directly below the unmanned aerial vehicle 101. The direct below design ensures that the whole device is more balanced, and the take-off and approach to the transmission line can be more stable. If the threaded pipe 103b is arranged at the end of the unmanned aerial vehicle 101, the unmanned aerial vehicle 101 will have a situation of "heavy head and light feet", which makes the unmanned aerial vehicle 101 not only difficult to take off, but also swing left and right when reaching the high altitude due to the unstable wind force, and is prone to contact and fall.

[0046] The limiting part 104 includes a limiting sleeve 104a arranged on the threaded pipe 103b and connected with the head frame 102, and a limiting protrusion 104b arranged on the limiting sleeve 104a and matched with the telescopic limiting groove 103c.

[0047] Preferably, the limiting sleeve 104a is fixedly arranged on the head frame 102, the limiting sleeve 104a is in sliding connection with the threaded pipe 103b, and the limiting protrusion 104b is in sliding connection with the telescopic limiting groove 103c, so as to limit the threaded pipe 103b from rotating. Therefore, the rotation of the threaded sleeve 103a can drive the threaded pipe 103b to extend or retract, thereby ensuring the normal operation of the device.

[0048] The power part 105 includes a power motor 105a arranged on the head frame 102, an input gear 105b arranged on the power motor 105a, an output gear 105c arranged on the threaded sleeve 103a and engaged with the input gear 105b, and an air flow plate 105d arranged on the head frame 102.

[0049] Preferably, the power motor 105a is a servo motor, which is fixedly arranged on the head frame 102 and provides power for the extension and retraction of the threaded pipe 103b. The input gear 105b is engaged with the output gear 105c, so that the power motor 105a can drive the threaded sleeve 103a to rotate, thereby ensuring the normal operation of the device.

[0050] The remaining structure is the same as that in Example 1.

[0051] During use, the starting motor 105a drives the input gear 105b to rotate the output gear 105c, which in turn drives the threaded sleeve 103a to rotate. Since the limiting protrusion 104b is engaged in the telescopic limiting groove 103c, the threaded tube 103b is limited. Therefore, the threaded sleeve 103a drives the threaded tube 103b to move, causing the threaded tube 103b to extend, thereby increasing the voltage detection distance.

[0052] Example 3

[0053] Referring to Figures 1 to 6, this is the third embodiment of the present invention. This embodiment differs from the second embodiment in that: the first sliding part 201 includes a first slip ring 201a disposed on the threaded tube 103b, a first slider 201b disposed on the first slip ring 201a, a first sliding plate 201c disposed on the first slider 201b and adapted to the threaded tube 103b, and a first through groove 201d disposed on the threaded tube 103b and adapted to the first slider 201b.

[0054] Preferably, the first slip ring 201a is slidably disposed on the threaded tube 103b, and the first slider 201b is slidably connected to the first through groove 201d to ensure the stability of the voltage detector 202a and prevent the voltage detector 202a from deflecting. The first sliding plate 201c increases the sliding stability of the first slip ring 201a and is also used to connect the second sliding part 302. The first through groove 201d not only prevents the first slip ring 201a from rotating, but also ensures that the first slip ring 201a can move.

[0055] The voltage testing unit 202 includes a voltage testing hook 202a disposed on the first slip ring 201a, an voltage detector 202b disposed on the voltage testing hook 202a, and a voltage testing spring 202c disposed on the voltage detector 202b and connected to the voltage testing hook 202a.

[0056] Preferably, the voltage detection hook 202a is used to hold the power transmission line, so that the stability of the voltage detection can be guaranteed even when the drone 101 is blown by unstable wind. The voltage detector 202b is used to contact the power transmission line to perform the voltage detection operation. The voltage detector 202b is slidably mounted on the voltage detection hook 202a. When the voltage detection hook 202a clamps the power transmission line, the voltage detection spring 202c not only ensures that the voltage detector 202b is in close contact with the power transmission line, but also prevents the voltage detection hook 202a from driving the voltage detector 202b to be forcibly squeezed and damaged.

[0057] The support part 203 comprises a support frame 203a arranged on the threaded pipe 103b, a support base 203b arranged on the support frame 203a, a support groove 203c arranged on the support base 203b, and a support sliding groove 203d arranged on the electricity testing hook 202a and connected with the support base 203b.

[0058] Preferably, the support frame 203a is an L-shaped support frame fixedly arranged on the threaded pipe 103b, so that the movement of the threaded pipe 103b can drive the electricity testing hook 202a and the support base 203b to move, thereby ensuring the normal use of the device. The support base 203b is adapted to the electricity testing hook 202a and used for clamping the power transmission line. The support groove 203c is convenient for the power transmission line to be clamped. The support groove 203c is provided with a rubber pad, thereby reducing the damage to the power transmission line. The support base 203b is slidingly arranged in the support sliding groove 203d, thereby increasing the stability of the electricity testing hook 202a.

[0059] The balance part 301 comprises a balance frame 301a arranged on the unmanned aerial vehicle 101 and a balance sliding sleeve 301b arranged on the balance frame 301a and adapted to the threaded pipe 103b.

[0060] Preferably, the balance frame 301a is located at the tail of the unmanned aerial vehicle 101. The balance frame 301a and the head frame 102 are both arranged to extend, thereby increasing the telescopic length of the threaded pipe 103b and the safe distance of electricity testing.

[0061] Preferably, the balance sliding sleeve 301b is fixedly arranged on the balance frame 301a and slidingly connected with the threaded pipe 103b, thereby supporting the threaded pipe 103b, reducing the stress of the threaded sleeve 103a, and increasing the service life of the device.
