[0002] In order to ensure the reliable operation of distribution network lines, line operation and maintenance personnel need to regularly inspect the distribution network lines and repair and eliminate line defects or faults detected during the inspection. For current maintenance operations, generally, the line needs to be powered off and then maintenance personnel can carry out the maintenance operations. To ensure the safety of maintenance personnel during line maintenance operations, it is necessary to detect the live condition of the lines at both ends of the fault point and hang grounding wires before the line maintenance operations.

[0003] Currently, during the live-line detection operation of distribution network lines, maintenance personnel need to climb to high-voltage towers and carry out manual live-line detection operations.

Detailed Description of the Invention

[0025] The present invention provides a live-line detection device and a live-line detection and grounding robot thereof. To make the purpose, technical solutions and effects of the present invention clearer and more definite, the following further describes the present invention in detail with reference to the accompanying drawings and by way of examples. It should be understood that the specific examples described herein are only used to explain the present invention and are not used to limit the present invention.

[0026] In the description of the present invention, it should be understood that the orientation or positional relationships indicated by terms such as "middle part", "inner side", "outer side", etc. are the orientation or positional relationships of the present invention based on the drawings, and are only for the convenience of describing the present invention and simplifying the description. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features.

[0027] Please refer to Figures 1 to 5, the present invention provides a voltage detection device, comprising a driving mechanism 1, a first swing arm 2, a second swing arm 3 and a first voltage detection mechanism 4. The first swing arm 2 is rotatably connected to the driving mechanism 1, the second swing arm 3 is rotatably connected to the first swing arm 2, and the first voltage detection mechanism 4 is arranged at the connection position of the first swing arm 2 and the second swing arm 3. A first voltage detection and alarm mechanism 5 is arranged on the first swing arm 2, and a second voltage detection and alarm mechanism 6 is arranged on the second swing arm 3.

[0028] In practical applications, this device is a part of the voltage detection and grounding robot. When in use, it needs to be installed on the voltage detection and grounding robot for cooperative use. The voltage detection and grounding robot further comprises a main control mechanism and a hoisting mechanism. The driving mechanism 1, the first voltage detection mechanism 4, the first voltage detection and alarm mechanism 5 and the second voltage detection and alarm mechanism 6 are respectively electrically connected to the main control mechanism. Maintenance personnel control the operation of this device by remotely controlling the main control mechanism. This device climbs and hangs on the distribution network line through the hoisting mechanism. The initial states of the first swing arm 2 and the second swing arm 3 are set to the folded state, and the first voltage detection mechanism 4 faces the distribution network line directly above the voltage detection and grounding robot. When the first voltage detection mechanism 4 touches the upper distribution network line, the first voltage detection mechanism 4 is connected to the distribution network line for voltage detection operation, and sends the voltage detection result to the maintenance personnel through the main control mechanism. The first swing arm 2 and the second swing arm 3 adjust the rotation angles according to the arrangement modes of the remaining two distribution network lines, so that the first voltage detection and alarm mechanism 5 and the second voltage detection and alarm mechanism 6 can respectively touch and detect the remaining two distribution network lines, thereby meeting the voltage detection operations of distribution network lines under different three-phase arrangement conditions, avoiding the operation risks of manual voltage detection, and having high operation efficiency.

[0029] In one embodiment, when the three distribution network lines are arranged vertically, after the first voltage detection mechanism 4 finishes detecting the voltage of the lowermost distribution network line, the first swing arm 2 and the second swing arm 3 turn upwards in sequence, so that the first voltage detection and alarm mechanism 5 and the second voltage detection and alarm mechanism 6 touch and detect the upper two distribution network lines in sequence, thereby meeting the voltage detection requirements of the vertically arranged distribution network lines.

[0030] In another embodiment, when the three distribution network lines are arranged horizontally, after the first voltage detection mechanism 4 finishes detecting the voltage of the leftmost or rightmost distribution network line, the first swing arm 2 and the second swing arm 3 turn left or right in sequence, so that the first voltage detection and alarm mechanism 5 and the second voltage detection and alarm mechanism 6 touch and detect the two side distribution network lines from left to right or from right to left, thereby meeting the voltage detection requirements of the horizontally arranged distribution network lines.

[0031] In another embodiment, when the three distribution network lines are arranged in a triangle, after the first live-line checking mechanism 4 has completed the live-line checking of the leftmost or rightmost distribution network line, the first swing arm 2 and the second swing arm 3 are flipped left or right in sequence, so that the first live-line checking and alarming mechanism 5 and the second live-line checking and alarming mechanism 6 touch and check the two distribution network lines on the side from left to right or from right to left. And because there is a certain height difference between the two distribution network lines on the side, the rotation angle between the first swing arm 2 and the second swing arm 3 can be adjusted to meet the height difference between the two distribution network lines, so as to meet the live-line checking requirements of the distribution network lines arranged in a triangle.

[0032] Further, as Figures 1 to 2 shown, a plurality of in-place detection mechanisms 7 are arranged on the first swing arm 2; by detecting the distance between the distribution network line and the first swing arm 2 and the second swing arm 3 through the in-place detection mechanism 7, the maintenance personnel can control the swing amplitude of the first swing arm 2 and the second swing arm 3 according to the distance data, so as to prevent the problem that the first swing arm 2 and the second swing arm 3 touch the distribution network line excessively, and improve the safety of using this device.

[0033] In this embodiment, the in-place detection mechanism 7 is an adjustable rotating rod type limit switch.

[0034] Further, as Figure 1 、 Figure 2 、 Figure 3 and Figure 5 shown, the first swing arm 2 and the second swing arm 3 are connected by a transmission mechanism 8, the driving mechanism 1 is in transmission connection with the transmission mechanism 8, and the first live-line checking mechanism 4 is fixedly connected to the transmission mechanism 8; by controlling the driving mechanism 1, the first swing arm 2 and the second swing arm 3 are rotated respectively, so as to adjust the swing amplitude of the first swing arm 2 and the second swing arm 3.

[0035] Further, as Figure 1 、 Figure 2 、 Figure 3 and Figure 5 shown, the first live-line checking mechanism 4 includes a live-line checking swing frame 41, the live-line checking swing frame 41 is arranged on one side of the transmission mechanism 8 through a mounting plate 42, the live-line checking swing frame 41 and the mounting plate 42 are rotatably connected, and a torsion spring 43 for resetting the live-line checking swing frame 41 is arranged between the live-line checking swing frame 41 and the mounting plate 42; when the live-line checking swing frame 41 touches the distribution network line, one side of the live-line checking swing frame 41 will be flipped downward under the influence of pressure, so as to avoid hard collision between the live-line checking swing frame 41 and the distribution network line and damage to the distribution network line. After the live-line checking swing frame 41 moves away from the distribution network line, the torsion spring 43 is used to reset the live-line checking swing frame 41 to restore it to the initial state.

[0036] Further, as Figure 5 shown, a sliding guide portion 44 protruding outward is provided in the middle of the top of the live-line checking swing frame 41; when the middle part of the live-line checking swing frame 41 touches the distribution network line, the distribution network line can be moved to either the left or the right side through the sliding guide portion 44, ensuring that the live-line checking swing frame 41 flips downward to one side under pressure, avoiding hard collision with the distribution network line and damage to the distribution network line.

[0037] In this embodiment, the sliding guide portion 44 is semicircular, and it is convenient to guide the distribution network line to fall to either the left or the right side through the semicircular sliding guide portion 44.

[0038] Further, as Figure 1 、 Figure 2 and Figure 4 shown, the first live-line checking and alarming mechanism 5 and the second live-line checking and alarming mechanism 6 have the same structure; the first live-line checking and alarming mechanism 5 includes a live-line checking alarm 51 and a touch frame 52, the live-line checking alarm 51 and the touch frame 52 are respectively detachably connected to the first swing arm 2, one end of the live-line checking alarm 51 is provided with a live-line checking portion, and the live-line checking portion is in contact with the touch frame 52; the contact area between the live-line checking alarm 51 and the distribution network line is increased through the touch frame 52, ensuring that the live-line checking alarm 51 can be connected to the distribution network line, so as to complete the touch live-line checking of the distribution network line; in addition, the installation positions of the live-line checking alarm 51 and the touch frame 52 on the first swing arm 2 and the second swing arm 3 can be adjusted, improving the flexibility of the use of this device.

[0039] In this embodiment, the live-line checking alarm 51 and the touch frame 52 are respectively detachably connected to the first swing arm 2 or the second swing arm 3 through snap clips 53.

[0040] Further, as Figures 1 to 3As shown in the figure, the driving mechanism 1 includes a frame 11, a first rotating motor 12 and a swinging seat 13. The first rotating motor 12 is arranged inside the frame 11. The swinging seat 13 is arranged on one side of the frame 11 and is fixedly connected to the output shaft of the first rotating motor 12. The swinging seat 13 is in transmission connection with the transmission mechanism 8. The swinging seat 13 is used to control the swinging of the second swing arm 3 and drive the first swing arm 2 to rotate. By driving the swinging seat 13 to rotate through the first rotating motor 12, the swinging seat 13 drives the first swing arm 2 to swing, thereby adjusting the swing amplitude of the first swing arm 2. And while the second swing arm 3 follows the swinging of the first swing arm 2, it can also drive the transmission mechanism 8 to rotate through the swinging seat 13, so that the first swing arm 2 can swing relative to the second swing arm 3, realizing the rotation of multiple joints, thereby improving the flexibility of use of the first swing arm 2 and the second swing arm 3 and meeting the live-line checking requirements of distribution network lines with different layout methods.

[0041] Further, as Figures 1 to 3 shown, the first swing arm 2 includes a transmission rod 21 and an insulating sleeve rod. The transmission mechanism 8 includes a worm 81 and a turbine 82. A second rotating motor 14 is arranged inside the swinging seat 13. The output shaft of the second rotating motor 14 is connected to the transmission rod 21. The insulating sleeve rod is sleeved on the transmission rod 21. One end of the transmission rod 21 is fixedly connected to the worm 81. One end of the second swing arm 3 is fixedly connected to the turbine 82. The worm 81 meshes with the turbine 82. During use, the second rotating motor 14 controls the relative rotation of the transmission rod 21 inside the insulating sleeve rod, and the transmission rod 21 drives the second swing arm 3 to swing through the worm 81 and the turbine 82, so that the second swing arm 3 rotates relative to the first swing arm 2. And the insulating sleeve rod plays a role of double protection. If there is high-voltage electricity in the distribution network line, the high-voltage electricity is isolated through the insulating sleeve rod to avoid damage to the second rotating motor 14. If the second rotating motor 14 leaks electricity, the leakage is isolated through the insulating sleeve rod to avoid affecting the live-line checking result of the live-line checking alarm 51.

[0042] In this embodiment, the transmission rod 21 is an insulating transmission rod 21, and the effect of electrical isolation between the distribution network line and the driving mechanism 1 is enhanced through the insulating transmission rod 21.

[0043] Further, as Figure 3 shown, the transmission mechanism 8 further includes a housing 83. The worm 81 and the turbine 82 are respectively arranged inside the housing 83. The housing 83 plays a role in protecting the worm 81 and the turbine 82.

[0044] In summary, during use, when the first power verification mechanism 4 touches the overhead power distribution line, the first power verification mechanism 4 is connected to the power distribution line for power verification operations. The first swing arm 2 and the second swing arm 3 adjust their rotation angles according to the layout of the remaining two power distribution lines, enabling the first power verification and alarm mechanism 5 and the second power verification and alarm mechanism 6 to respectively touch and verify the remaining two power distribution lines. This can thus meet the power verification requirements for power distribution lines in different three-phase arrangement conditions, avoid the operational risks of manual power verification, and achieve high operational efficiency.

[0045] The present invention also correspondingly provides a power verification and grounding robot, which includes the power verification device as described above.

[0046] It can be understood that for those of ordinary skill in the art, equivalent substitutions or modifications can be made based on the technical solutions and inventive concepts of the present invention, and all such changes or substitutions should fall within the protection scope of the appended claims of the present invention.
