Description

Technical Field

[0001] The present invention relates to the technical field of power transmission line deicing, and in particular to a power transmission line deicing device for electric power. Background Art

[0002] As a key component of power transmission, transmission lines are prone to icing under adverse weather conditions (such as low temperature, rain and snow). Icing not only increases the mechanical load on cables, but can also lead to serious consequences such as line breakage and tower collapse, seriously affecting the safe and stable operation of the power system.

[0003] At present, deicing technologies for transmission lines mainly include physical methods (such as heating and vibration), chemical methods (using deicing agents), and deicing robots. However, these methods have their own limitations:

[0004] Physical methods usually require frequent manual intervention and a long operation cycle, resulting in high costs for the entire de-icing process and low de-icing efficiency;

[0005] Chemical methods face similar problems and may have some impact on the environment;

[0006] Although deicing robots can improve the overall deicing efficiency to a certain extent, existing deicing robots can usually only de-ice the transmission line itself, but cannot effectively remove the ice on the insulators at the ends of the transmission line. Insulator icing is particularly critical because it can significantly reduce the insulation performance of the insulator, thereby causing electrical faults such as flashover and short circuit, which in turn leads to power transmission interruption.

[0007] Therefore, although the existing deicing robots can improve deicing efficiency in some aspects, due to their limited ability to handle icing on insulators, manual intervention is still required, which limits the effectiveness of their comprehensive application. Summary of the invention

[0037] like Fig.11 As shown, it also includes a protective shell 37 and a corrugated protective sleeve 38. The left parts of the front and rear sides of the shell 1 are connected to the protective shell 37. The two driving motors II32 are respectively located in the protective shells 37 on the front and rear sides of the shell 1, and the driving rod 3201 rotates and penetrates the left sides of the protective shells 37 on the front and rear sides of the shell 1.

[0038] First, the shell 1 and the top plate 2 are placed on the upper and lower sides of the transmission line body 001 respectively, and then the shell 1 and the top plate 2 are moved in the direction close to the transmission line body 001, so that the moving wheels 18 on the shell 1 and the top plate 2 can clamp the transmission line body 001, and the transmission line body 001 can be located between the arc plates 4 on the upper and lower sides, and then the top plate 2 is fixed to the shell 1 by bolts, so that the shell 1 and the top plate 2 can be fixed to the transmission line body 001; then the driving motor I 13 drives the rotating rod 12 to rotate, and the rotating rod 12 can drive the short rod 20 to rotate through the bevel gear 23, and the short rod 20 can drive the rotating rod 20 on the upper middle side through the spur gear 21. The shaft 17 rotates, and the upper middle shaft 17 can drive the lower middle shaft 17 to rotate through the transmission gear 22. At this time, the two middle shafts 17 can drive the moving wheels 18 thereon to rotate, thereby driving the entire device to move along the transmission line body 001. The moving wheels 18 on the remaining shafts 17 can also roll on the transmission line body 001 to assist the stable movement of the entire device; at the same time, the rotation of the rotating rod 12 can drive the driving gear 14 to rotate, and the driving gear 14 can drive the arc plate 4 to rotate through the driven half gear ring 15, and the arc plate 4 can drive the arc cutter 5 to rotate, so that the arc cutter 5 can automatically de-ice the surface of the transmission line body 001;When the entire device moves to the end of the transmission line body 001 (i.e., the housing 1 is located on the side of the insulator body 002), the drive motor I13 can be controlled to stop working, and then the servo motor 26 drives the screw 27 to rotate, and the screw 27 can drive the sliding plate 25 to move to the left along the guide rod 24, and the sliding plate 25 can drive the sliding block 28, the nitrogen spring 29 and the wedge plate 35 to move to the left together, and the sliding block 28 can push the sliding frame 7 to move to the left along the fixed guide rail 6, and the sliding frame 7 can drive the shovel plate 8 to move to the left to the top of the insulator body 002, until the sliding block 28 moves to the left to contact the right side of the fixed shell 30. When the sliding block 28 and the sliding frame 7 are touched, the sliding block 28 and the sliding frame 7 stop moving to the left, and the sliding frame 7 is just separated from the fixed guide rail 6. At this time, the sliding guide rail 33 can continue to support and stabilize the sliding frame 7, and then the sliding plate 25 will drive the wedge plate 35 to continue to move to the left, and the nitrogen spring 29 is compressed. When the wedge plate 35 contacts the lifting rod 34, it will squeeze the lifting rod 34 to move downward, and the lifting rod 34 can drive the contact block 36 to move downward. The contact block 36 will squeeze the sliding guide rail 33 to move downward, and the reset spring 3103 is compressed. The sliding guide rail 33 can drive the sliding frame 7 and the shovel plate 8 to move downward until the sliding guide rail 33 is completely moved to the through hole. 3101, at this time, the right end of the sliding frame 7 will be separated from the sliding block 28, and the shovel plate 8 will be close to the surface of the insulator body 002, and then the power supply module 10 can be used to power the heating wire 9, the heating wire 9 can generate heat, and can transfer the heat to the ice on the surface of the insulator body 002 through the shovel plate 8, and at the same time, the rotating disk 31 can be driven by the driving motor II 32 and the driving rod 3201 to rotate back and forth, and the rotating disk 31 can drive the sliding guide rail 33, the sliding frame 7 and the shovel plate 8 to rotate back and forth, so that the ice on the surface of the insulator body 002 can be scraped off to achieve the deicing effect, and the sliding frame 7 and the shovel plate 8 can rotate back and forth. The rotation angle of the movement should be less than 360 degrees, so as to prevent the sliding frame 7 from colliding with the connection between the power transmission line body 001 and the insulator body 002 and being damaged. Due to the heating effect of the heating wire 9, the deicing effect of the insulator body 002 as a whole can be guaranteed. Since the contact block 36 and the sliding guide rail 33 are in contact, the contact block 36 will not affect the free rotation of the sliding guide rail 33, and when the sliding guide rail 33 rotates to separate from the contact block 36, the inner wall of the fixed shell 30 can take over the limiting work of the contact block 36 (pressing the sliding guide rail 33) to keep the sliding guide rail 33 in the position in the through hole 3101;After de-icing is completed, the power supply module 10 and the drive motor II 32 are turned off, and then the servo motor 26 drives the screw rod 27 to reverse, and the screw rod 27 can drive the sliding plate 25 to move rightward along the guide rod 24 to reset, and the sliding plate 25 can drive the wedge plate 35 to move rightward, the sliding block 28 does not move, and the nitrogen spring 29 gradually returns to its original state, so that the wedge plate 35 is separated from the lifting rod 34, and the reset spring 3103 will return to its original state, driving the sliding guide rail 33 to move upward and separate from the through hole 3101, and the sliding guide rail 33 can squeeze the contact block 36 and the lifting rod 34 to move upward and reset, and the sliding guide rail 33 can drive the sliding frame 7 and the shovel plate 8 to move upward. The right end of the sliding frame 7 is reconnected with the sliding block 28, and then the sliding plate 25 can drive the sliding block 28 to move rightward and reset through the nitrogen spring 29.
