Description

Technical Field

[0001] The utility model relates to the technical field of cable deicing, in particular to a multi-mode deicing mechanism for a power transmission line. Background Art

[0002] Cable is a general term for optical cables, electrical cables and other items. Cables have many uses, mainly used for control installation, connecting equipment, transmitting electricity and other multiple functions. They are common and indispensable in daily life. In order to ensure the normal operation of power cables and ensure the safety and stability of power supply in the power system, cables need to be maintained regularly. When maintaining cables in winter, cables need to be de-iced. The current cable maintenance industry does not have a multi-functional robot dedicated to cable de-icing. Manual de-icing or machines with only one function have low operating efficiency and are not suitable for a variety of working conditions. Operators are at risk of being hit by falling ice when de-icing. Therefore, a cable de-icing machine that can replace manual labor and is suitable for a variety of cable icing conditions is urgently needed;

[0003] The existing technology is manual deicing, which is carried out manually with deicing tools, which is inefficient and has high operating risks. The existing deicing machines have only one function and cannot handle the mixed existence of hard ice layer and soft rime at the same time, and require a clamping device and cable to clamp and advance, which will damage the insulation of the cable. Utility Model Content

[0004] The purpose of the utility model is to provide a multi-mode deicing mechanism for a power transmission line to solve the existing problems raised in the above-mentioned background technology.

[0006] Preferably, a vibrating hammer is provided at the bottom of the three groups of impact rods, which can improve the vibration effect on the cable and fully remove the crushed ice.

[0007] Preferably, push rods are provided on both sides of the two groups of impact rods on the right and on one side of the group of impact rods on the left, and the heights of the five groups of push rods increase from right to left. The push rod is connected to a group of push rods, so that when the group of impact rods on the right is pushed, the remaining two groups of impact rods can be driven to move up together.

[0008] Preferably, a groove matching with the special-shaped cam is formed on one side of one inner end of the mounting frame, so as to provide a movable space for the special-shaped cam.

[0009] Preferably, the mounting frame is in an I-shape for ease of installation.

No clamping device is required, and it can be better integrated with the drone. Regardless of whether the deicer is faulty, the drone can be used to raise and lower the cables at any time. It only has a single power source, a more reliable mechanical structure, lower energy consumption, longer working time and lighter overall weight. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-4 , the utility model provides an embodiment: a multi-mode deicing mechanism for a power transmission line, comprising a mounting frame 1, the mounting frame 1 is in an I-shaped shape for easy installation, a mounting bin 7 is provided on one side of the inner side of the mounting frame 1, a rotating shaft A5 and a rotating shaft B13 are sleeved on both sides of the inner side of the mounting frame 1, a reduction motor 2 is provided on one side of one end of the mounting frame 1, a driving bevel gear 3 is provided at the output end of the reduction motor 2, a driven bevel gear 4 meshing with the driving bevel gear 3 is provided at one end of the outer side of the rotating shaft A5, a pulley A11 is provided at one end of the outer side of the rotating shaft B13, a pulley B15 is provided at one end of the outer side of the rotating shaft A5, a transmission belt 10 is provided on the outer transmission sleeves of the pulleys A11 and B15, two sets of deicing cone gears 12 are symmetrically provided in the middle of the outer side of the rotating shaft B13, a walking wheel 6 is provided in the middle of the outer side of the rotating shaft A5, and the walking wheel 6 is a rubber wheel;

[0019] Two groups of impact rods 9 are sleeved on one side of the top of the inner side of the installation bin 7, and a limit block is provided on the top of one side of the three groups of impact rods 9, and the limit block is located at the bottom of the spring 8. When the impact rod 9 is pushed up, the spring 8 can be pushed and squeezed by the limit block. Push rods are provided on both sides of the two groups of impact rods 9 on the right and one side of the group of impact rods 9 on the left, and the heights of the five groups of push rods increase from right to left. The lever 16 is connected to one group of push rods, so that when the right group of impact rods 9 is pushed, the remaining two groups of impact rods 9 can be driven to move up together. Vibrating hammers are provided at the bottom of the three groups of impact rods 9, which can enhance the impact and de-icing effect on the cable and fully remove the crushed ice. The top of the outer side of the three groups of impact rods 9 is sleeved with a spring 8, and a lever 16 is provided on one side of one group of impact rods 9. One end of the walking wheel 6 is provided with a special-shaped cam 14 that matches the lever 16, and one side of one end of the inner side of the mounting frame 1 is provided with a groove that matches the special-shaped cam 14. When the special-shaped cam 14 rotates, it can rotate along the groove.

[0020] Working principle: When the device is used, it is installed on a drone, and the drone is used to move the device to the cable, so that the cable is stuck in the inner side of the walking wheel 6 and the two sets of deicing cone gears 12. When deicing the cable, the reduction motor 2 can be started, and then the reduction motor 2 can drive the rotating shaft A5 to rotate under the transmission of the active bevel gear 3 and the driven bevel gear 4. At this time, the rotating shaft A5 can drive the walking wheel 6 to operate, so that the device can move along the cable. At the same time, the rotating shaft A5 can also drive the pulley B15. The pulley B15 drives the rotating shaft B13 to rotate through the transmission belt 10 and the pulley A11. At this time, the rotating shaft B13 drives the two sets of deicing cone gears 12 to rotate, and the gravity of the entire machine and the tooth blades of the deicing cone gears 12 are used to crush the rime and ice on the cable;

[0021] When the traveling wheel 6 rotates, the special-shaped cam 14 can be driven to rotate, and the special-shaped cam 14 can intermittently push the lever 16, so that the three groups of impact rods 9 can squeeze the spring 8 to move upward under the contact of the push rods with increasing heights. When the effect of the special-shaped cam 14 ends, the three groups of impact rods 9 will be released in turn to impact the cable, and the ice on the cable will be shaken off by the vibration force.
