Description

Technical Field

[0001] The present invention relates to the technical field of electric power construction and maintenance, and in particular to an electric testing device and an electric testing method using an electric test pen suspended from a drone. Background Art

[0002] During the construction of transmission line stringing and subsequent operation and maintenance, the electrician's pen is an indispensable tool for testing electricity. Workers need to carry the electrician's pen to the high-voltage tower to test points before work. When crossing some important power lines, the crossed lines need to be shut down. However, there is still induced electricity on the lines after the power outage, and induced electricity will also be generated on the laid conductors. Therefore, it is necessary to test the lines that have been shut down with the electrician's pen and then ground them to eliminate the induced electricity.

[0003] In addition, when the line is under inspection and maintenance, it is necessary to shut down the operating line for maintenance. However, there is still a lot of static electricity on the line after the power outage. The maintenance personnel need to ground the maintenance line, release the static electricity, and then test the electricity to confirm that there is no power outage and the static electricity has been released before they can safely inspect and maintain.

[0004] At present, the most commonly used electrician test pens for testing electricity in power line construction and maintenance work are about 6-8 meters. One end of the electrician test pen is an insulating rod with sections and the other end is an alarm. When testing electricity, the high-altitude operator holds the electrician test pen and sends it to the vicinity of the wire for testing.

[0005] There are several problems with manual electrical testing:

[0006] (1) High labor intensity: Carrying an electrician's pen is cumbersome and labor-intensive for workers working at heights; testing is difficult, and the electrician's pen needs to be stretched section by section for electrical testing;

[0007] (2) High safety risks: When the electrical tester performs electrical testing at high altitudes with a handheld electrical test pen, there is a certain risk of contact points;

[0008] (3) Low efficiency of electrical testing: Workers working at heights need to be above the tower, which results in low efficiency of electrical testing. Summary of the invention

[0009] The purpose of the present invention is to provide an electric testing device and an electric testing method for a drone suspended electric testing pen.

[0010] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0011] A test pen test device for an unmanned aerial vehicle comprises an unmanned aerial vehicle, wherein a remote control unhooking device is connected to the lower part of the unmanned aerial vehicle, a hanging ring is connected to the lower part of the unhooking device, and the hanging ring can be separated from the remote control unhooking device under instructions; a vertical rigid insulating rod is connected to the hanging ring downward, and the lower end of the vertical rigid insulating rod is connected to a horizontal rigid insulating rod, and the horizontal rigid insulating rod and the vertical rigid insulating rod are arranged in an inverted T shape;

[0012] Both ends of the horizontal rigid insulating rod are respectively connected downward with insulating ropes, and the electric test pen is horizontally connected to the lower ends of the two insulating ropes.

[0013] The upper end of the vertical rigid insulating rod is connected to the hanging ring through a mechanical unhooking device.

When the driving mechanism drives the worm wheel to rotate forward and reversely, the worm wheel drives the worm to rotate so that the worm moves axially, and the worm drives the suspension pin shaft to move through the connecting plate, thereby realizing the switching of the suspension pin shaft relative to the H-shaped main board between the closed state and the exit state.

[0015] The H-shaped main board consists of two wing plates and a horizontal plate fixedly connecting the two wing plates. The H-shaped main board forms an upper opening and a lower opening on the upper and lower sides of the horizontal plate, respectively. An upper pin shaft hole and a lower pin shaft hole are respectively provided on the wing plates at the upper opening and the lower opening. The upper pin shaft hole is used to connect with the drone, and the suspension pin shaft slides through the lower pin shaft hole; a worm guide hole is provided above the lower pin shaft hole of the lower opening, and the worm slides through the worm guide hole.

[0016] The worm guide hole is provided with a sink for installing a positioning copper sleeve.

[0017] The other end of the worm is provided with a limiting boss.

[0018] The driving mechanism includes a right-angle motor fixedly mounted on an H-shaped mainboard, and a power supply for supplying power to the right-angle motor. The right-angle motor is connected to a controller, and the controller is remotely controlled by a remote controller; the remote controller remotely sends a signal to the controller, and the controller issues a command to control the operation of the right-angle motor after receiving the signal.

[0019] The right-angle motor is fixedly mounted on the side of the H-shaped mainboard, and the controller and the power supply are respectively fixedly mounted on the two wing panels of the H-shaped mainboard.

[0020] The present invention also discloses a method for testing electricity by using an electric test pen while hanging on a drone. Using the electric test pen while hanging on a drone, the method comprises the following steps:

[0021] (1) Connect the vertical rigid insulating rod to the remote control release device at the lower end of the drone through a hanging ring on the ground, and install an electric test pen at the lower end of the insulating rope;

[0022] (2) Start the drone, manually lift the vertical rigid insulating rod, the horizontal rigid insulating rod and the voltage test pen to assist the drone in taking off, until the voltage test pen is safely off the ground;

[0023] (3) After the drone is controlled to fly diagonally above the wire, the drone uses the electrician's test pen to gradually move closer to the wire to perform the drone electrician's test;

[0024] (4) After the UAV electrical test is completed, the UAV is controlled to fly down with the test pen. After the ground personnel assist in catching the test pen, the UAV continues to fall. After the ground personnel assist in catching the horizontal rigid insulating rod, the remote control unhooker is operated to drop the entire set of test pens, insulating ropes, vertical rigid insulating rods and horizontal rigid insulating rods together to complete the UAV electrical test operation.

[0025] Beneficial effects of the present invention:

[0026] 1. The present invention provides an electric testing device and an electric testing method with a drone suspended electric test pen. A ground-based remote-controlled drone carries the electric test pen and hovers near a wire. The remote-controlled drone tests the electric test pen to measure whether the wire is energized. After the electric test, the remote-controlled drone returns with the electric test pen, avoiding personnel from climbing a tower.

[0037] The specific implementation modes of the present invention are described in detail below with reference to the accompanying drawings.

[0038] like Figures 1 to 9 As shown, this embodiment discloses a UAV hanging electric test pen electric test device, including a UAV 1, a remote control unhooking device 2 is connected below the UAV 1, the remote control unhooking device 2 is connected downwardly with a hanging ring 3, and the remote control unhooking device 2 can separate the hanging ring 3 from the remote control unhooking device 2 under instructions; the hanging ring 3 is connected downwardly with a vertical rigid insulating rod 5, the lower end of the vertical rigid insulating rod 5 is connected to a horizontal rigid insulating rod 6, and the horizontal rigid insulating rod 6 and the vertical rigid insulating rod 5 are arranged in an inverted T shape. The two ends of the horizontal rigid insulating rod 6 are respectively connected downwardly with insulating ropes 7, and the electric test pen 8 is horizontally connected to the lower ends of the two insulating ropes 7.

[0039] In this embodiment, the upper end of the vertical rigid insulating rod 5 is connected to the hanging ring 3 through a mechanical decoupling device 4, which is a prior art to prevent the vertical rigid insulating rod 5 from being separated from the drone 1 when the remote control decoupling device 2 is not working.

[0040] In this embodiment, the remote control unhooker includes an H-shaped main board 17, which is composed of two wing plates and a horizontal plate horizontally fixedly connecting the two wing plates. The H-shaped main board forms an upper opening and a lower opening on the upper and lower sides of the horizontal plate, respectively. An upper pin shaft hole 171 and a lower pin shaft hole 172 are respectively provided on the wing plates at the upper opening and the lower opening. The upper pin shaft hole 172 is used to connect with the drone 1, and the lower pin shaft hole slides through the suspension pin shaft 16, and the hanging ring 3 is hung on the suspension pin shaft 16 from the lower opening.

[0041] A worm 14 is provided on the H-shaped main board 17 in parallel with the suspension pin, and the worm 14 is slidably matched with the H-shaped main board 17, and one end of the worm 14 is connected to the suspension pin 16 through a connecting plate 15. Specifically, the two ends of the connecting plate 15 are fixed to the corresponding worm 14 and the suspension pin 16 by bolts.

[0042] The H-shaped main board 17 is provided with a worm guide hole 173 above the lower pin hole of the lower opening, and the worm 14 slides through the worm guide hole 173. A limiting boss is provided at the other end of the worm to prevent the worm 14 from exiting the H-shaped main board 17.

[0043] The worm guide hole 173 is provided with a sink for installing a positioning copper sleeve to ensure that the worm can slide smoothly therein.

[0044] A worm wheel 13 is provided in cooperation with the worm 14, and the worm wheel 13 is connected to a driving mechanism. When the driving mechanism drives the worm wheel 13 to rotate forward and reversely, the worm wheel 3 drives the worm 14 to rotate and causes the worm 14 to move axially. The worm 14 drives the suspension pin 16 to move through the connecting plate 15, thereby realizing the switching of the suspension pin 16 between the closed state and the exit state relative to the H-shaped main board, which can meet the needs of rapid installation and disassembly of the suspension pin.

[0045] In this embodiment, the driving mechanism includes a right-angle motor 18 fixedly mounted on an H-shaped mainboard, and a power supply 12 (preferably a lithium battery) for powering the right-angle motor 18. The right-angle motor 18 is connected to a controller 11, and the controller 11 is remotely controlled by a remote controller; the remote controller remotely sends a signal to the controller 11, and the controller 11 sends a command to control the operation of the right-angle motor 18 after receiving the signal.

[0046] During specific installation, the right-angle motor 18 is fixedly mounted on the side of the H-shaped mainboard 17, and the controller 11 and the power supply 12 are respectively fixedly mounted on the two wing panels of the H-shaped mainboard 17 to ensure the overall volume and integration of the device.

[0047] When the hanging ring 3 is separated from the remote control unhooking device 2, the remote control only needs to send a signal to the controller. After receiving the signal, the controller issues an instruction to control the right-angle motor 18 to reverse. The right-angle motor 18 reverses and drives the worm wheel 13 to rotate in the opposite direction, thereby driving the worm 14 to withdraw in the opposite direction. The worm 14 and the suspension pin 16 are connected by a connecting plate, thereby driving the suspension pin 16 to withdraw, and the hanging ring 3 is separated from the remote control unhooking device 2.

[0048] This embodiment also discloses a method for testing electricity using a test pen while hanging on a drone, and using the test pen to test electricity using the device, the method comprises the following steps:

After the ground personnel assist in catching the test pen 8, the UAV continues to fall. After the ground personnel assist in catching the horizontal rigid insulating rod 6, the remote control unhooker 2 is remotely controlled to operate and drop the entire set of test pen 8, insulating rope 7, vertical rigid insulating rod 5 and horizontal rigid insulating rod 6 together, thus completing the UAV electrical test operation.

A ground-based remote-controlled drone carries the electric test pen and hovers near a wire. The remote-controlled drone tests the electric test pen to measure whether the wire is energized. After the electric test, the remote-controlled drone returns with the electric test pen, avoiding personnel from climbing a tower. Then, line construction or overhaul and maintenance are carried out, thereby improving the safety efficiency of electric testing and construction safety.
