Description

Technical Field

[0001] The present application relates to the technical field of line loss detection, and in particular to a line loss detection mechanism for electric power engineering. Background Art

[0002] Line loss refers to the loss of electric energy on the transmission line, which can also be called line loss load. The main causes of line loss include line insulation aging, metering failures, and electricity theft by users. Line loss is usually used to assess the economic efficiency of power system operation, and can indirectly reflect the technical conditions and management level of power supply. Power supply companies need to regularly detect line losses on transmission lines.

[0025] Embodiment 2

[0026] Reference Figure 2 and Figure 4 The height adjustment component includes a servo motor 10 fixedly connected to the surface of the base 1, and the output end of the servo motor 10 is fixedly connected to a worm 11 through a coupling. The outside of the worm 11 is meshed with a worm wheel 12, and the inside of the worm wheel 12 is fixedly connected to a second screw rod 13, and the outside of the second screw rod 13 is threadedly connected to one of the connecting ears 22. Start the servo motor 10, and the servo motor 10 drives the worm 11 to rotate. The rotation of the worm 11 will drive the worm wheel 12 to rotate. The rotation of the worm wheel 12 will drive the second screw rod 13 inside it to rotate, so that the second screw rod 13 will rotate, and the rotation of the second screw rod 13 will drive one of the connecting ears 22 to rise and fall, thereby realizing the lifting and lowering of the detection platform 2.

[0027] Reference Figure 2 and Figure 5 The clamping assembly includes a clamping platform 14 fixedly connected to the top of the detection platform 2 and located at both ends of the transverse groove 3. A rectangular cavity 15 is provided inside the clamping platform 14, and a lower arc groove 16 is provided on the bottom inner wall of the rectangular cavity 15. A screw 17 is threadedly connected to the top wall of the clamping platform 14. The bottom end of the screw 17 extends to the inside of the rectangular cavity 15 and is rotatably connected to a clamping block 18. An upper arc groove 19 is provided at the bottom of the clamping block 18. The two ends of the cable are passed through the upper arc groove 19 and the lower arc groove 16 of the two clamping blocks 18. By rotating the screw 17, the rotation of the screw 17 will drive the clamping block 18 to move toward the cable surface, and the upper arc groove 19 and the lower arc groove 16 are closely fitted with the cable surface, thereby achieving clamping and fixing of the cable surface.

[0029] The implementation principle of a line loss detection mechanism for an electric power project in an embodiment of the present application is as follows: start the servo motor 10, and the servo motor 10 drives the worm 11 to rotate.

The rotation of the second screw 13 drives one of the connecting ears 22 to rise and fall, thereby realizing the lifting and lowering of the detection platform 2. While the detection platform 2 moves outside the first screw 5, it will also slide outside the limit rod 21. The limit rod 21 can limit the movement of the detection platform 2 outside the first screw 5 to avoid rotational deviation of the detection platform 2 when it moves outside the first screw 5.

The two side walls of the clamping block 18 fit tightly with the inner wall of the rectangular cavity 15, thereby preventing the clamping block 18 from rotating when the screw 17 rotates. When the two ends of the cable are fixed by the clamping assembly, by starting the forward and reverse motor 4, the forward and reverse motor 4 will drive the first screw rod 5 to rotate. The rotation of the first screw rod 5 will drive the slider 6 and the detection seat 7 to slide outside the first screw rod 5. The bottom of the slider 6 fits tightly with the bottom inner wall of the transverse groove 3, thereby preventing the slider 6 from rotating and deviating when the first screw rod 5 moves outside. The detection seat 7 moves, and the detection cavity 8 and the three detection cameras 9 inside it will also move. The three detection cameras 9 can perform all-round line loss detection on the cable surface while moving. The detection process does not need to touch the cable, which ensures the safety of cable detection. The detection camera 9 displays the cable line loss situation on the data display screen 20, so that the cable line loss situation can be intuitively understood.
