Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of electric leakage detection, and particularly relates to a power transmission line electric leakage detection device. BACKGROUND

[0002] The power transmission line is used to realize the connection of the power transmission line to the power transmission line through the circuit breaker and other control devices after the voltage of the power generated by the generator is boosted by the transformer. The power transmission line is divided into overhead power transmission line and cable line. Since the overhead line has simple line structure, short construction period, low construction cost, large transmission capacity and convenient maintenance and repair, the overhead power transmission line is widely used at present except for special cases (such as narrow ground and crowded line or special requirements). The overhead power transmission line is connected with the wind power plant or the transformer substation to form a power system or a power grid to transmit power. However, some power transmission lines are erected in remote high-altitude areas and are often affected by strong wind, freezing and other severe weather, which easily causes the surface damage of the power transmission line and leads to the occurrence of the electric leakage phenomenon. Therefore, it is necessary to regularly check whether the power transmission line has the electric leakage phenomenon to ensure the normal work of the power transmission line.

[0003] In the prior art, the power transmission line is detected by the electric leakage detection device to determine whether the power transmission line has the electric leakage phenomenon. Although the existing electric leakage detection device can detect the position of the electric leakage of the power transmission line, the position of the electric leakage of the power transmission line cannot be marked, and the position of the electric leakage cannot be quickly found during the subsequent repair of the electric leakage power transmission line, thereby reducing the work efficiency of the repair.

[0015] The beneficial effects of the present application are:

[0016] 1) After the detection mechanism detects that the power transmission line has a leakage phenomenon, the marking mechanism marks the power transmission line, so that the position of the leakage can be quickly found during subsequent maintenance, thereby improving the work efficiency of the maintenance.

[0017] 2) When the power transmission line contacts the first driving roller and the second driving roller, the U-shaped frame is moved upward, the two rollers are located on both sides of the power transmission line, and the U-shaped rod is fixed to the base through the locking bolt, the bidirectional threaded rod extending to the outside of the U-shaped rod is rotated, the sliding block moves along the bidirectional threaded rod and the guide rod, so that the two rollers contact the power transmission line, and under the action of the walking mechanism and the auxiliary mechanism, the power transmission line can be contacted in the up-down and left-right directions, thereby ensuring the stability of the whole device during movement.

[0018] 3) A rotating disk is installed at one end of the bidirectional threaded rod extending into the U-shaped rod. The bidirectional threaded rod is rotated by rotating the rotating disk, which facilitates the rotation of the bidirectional threaded rod.

[0019] 4) The movement of the two sliders brings the two first arc-shaped frames closer together. When the two rollers contact the power transmission line, the two first arc-shaped frames do not make contact. The bidirectional threaded rod continues to rotate, causing the two sliders to continue moving. Since the rollers cannot continue to move due to contact with the power transmission line, the moving rod moves along the cavity into the slider as the sliders move. At this time, the first spring is in a compressed state until the two first arc-shaped frames contact the bidirectional threaded rod and stop rotating. At this time, the two first arc-shaped frames, the arc plate, and the arc gear ring contact to form a closed loop. The third motor drives the fifth gear to rotate. The fifth gear meshes with the arc gear ring, causing the arc plate to rotate inside the two first arc-shaped frames. The cleaning cone located on the arc plate rotates accordingly to clean the debris attached to the power transmission line, facilitating the movement of the device and the detection of leakage current, thus improving work efficiency.

[0020] 5) Multiple second sleeves are evenly arranged in the circumferential direction on the inner side of the arc plate. The cleaning cone is threaded inside the second sleeve. The height of the cleaning cone can be adjusted by rotating the cleaning cone, thereby meeting the needs of transmission lines of different diameters and expanding the application range of the device.

[0021] 6) One end of the arc plate is equipped with a protrusion, and the other end is provided with a groove that matches the protrusion. The cooperation between the protrusion and the groove makes the movement of the two arc plates more closely connected, which helps to improve the working efficiency of the cleaning mechanism.

[0022] 7) The extension rod moves the U-shaped frame downwards, positioning the suspended printing plate directly above the power transmission line. The fourth motor then drives the second shaft to rotate, causing the sixth gear on the second shaft to rotate as well. The seventh gear on the second shaft meshes with the sixth gear, further rotating the second shaft. The rotating cam then presses against the annular plate, which, through the upright rod, moves the printing plate downwards. The suspended printing plate then contacts the power transmission line to mark it. The other printing plates then contact the inkpad to apply ink. The third shaft rotates through the cooperation of the lever and the dial, causing the turntable on the third shaft to rotate as well. This allows the other ink-applied printing plates to mark the power transmission line, thus continuously marking the location of any leakage in the power transmission line. This enables quick location of the leakage during subsequent maintenance, thereby improving maintenance efficiency. Attached Figure Description

A fifth gear 404 is installed at the end of the output shaft of the third motor 403. The fifth gear 404 is meshingly connected with the arc-shaped gear ring 406. The third motor 403 is electrically connected with the battery 8 and the controller 7. The movement of the two sliding blocks 305 causes the two first arc-shaped frames 402 to approach each other. When the two rollers 307 contact the power transmission line, the two first arc-shaped frames 402 do not contact each other. The continuous rotation of the bidirectional threaded rod 303 causes the two sliding blocks 305 to continue to move. Since the rollers 307 cannot continue to move due to the contact with the power transmission line, the moving rod 306 moves along the cavity 310 towards the inside of the sliding block 305 when the sliding block 305 moves. At this time, the first spring 309 is in a compressed state. Until the two first arc-shaped frames 402 contact each other, the bidirectional threaded rod 303 stops rotating. At this time, the two first arc-shaped frames 402, the arc-shaped plate 405, and the arc-shaped gear ring 406 are in contact and form a closed loop. The operation of the third motor 403 drives the fifth gear 404 to rotate. The meshing of the fifth gear 404 and the arc-shaped gear ring 406 drives the arc-shaped plate 405 to rotate inside the two first arc-shaped frames 402. The cleaning cones 408 on the arc-shaped plate 405 rotate to clean the garbage attached to the power transmission line. This facilitates the movement of the device and the detection of electric leakage, thereby improving the work efficiency.

The cleaning cones 408 are threadedly installed in the interiors of the second sleeves 407. The height of the cleaning cones 408 can be adjusted by rotating the cleaning cones 408, thereby meeting the use of power transmission lines of different diameters and expanding the use range of the device.
