Description

Technical Field

[0001] This utility model relates to the field of power transmission line protection, and in particular to a power transmission line antifreeze device. Background Technology

[0002] Transmission line antifreeze devices are mainly used to prevent power lines and related equipment from icing and freezing in severe weather conditions such as low temperatures, rain, snow, and freezing. By actively removing ice or preventing icing, they ensure the normal operation of equipment, reduce faults such as line breaks, tower collapses, and short circuits caused by freezing, and reduce manual maintenance costs and power outage losses. They are widely used in high-voltage transmission lines (especially those crossing mountains and regions), distribution lines, and various power equipment that are susceptible to low-temperature freezing. Existing transmission line antifreeze devices mainly include a drive mechanism, actuators, and auxiliary positioning components. The drive mechanism often uses a small motor or hydraulic device. Actuators commonly include ice scrapers that conform to the curvature of the conductor, rotatable nylon brushes, or elastic scrapers, which peel off ice through reciprocating or circular motion. Auxiliary positioning components include guide wheels and clamping mechanisms, which are used to fix the device to the conductor and limit its movement trajectory.

[0003] Existing antifreeze devices for power transmission lines rely on mechanical movement to peel off ice. The mechanical parts (such as ice scrapers and rotating brushes) are in direct contact with the surface of the conductors and equipment. Long-term friction can easily cause line wear, insulation damage, and even lead to safety hazards such as broken conductor strands.

[0004] Therefore, a power transmission line antifreeze device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a power transmission line antifreeze device, which aims to improve the problem of line wear and insulation layer damage caused by long-term friction of mechanical parts.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a power transmission line antifreeze device, comprising a base plate, a placement box fixedly connected to the bottom of the base plate, a second drive device fixedly connected inside the placement box, a rotating shaft fixedly connected to the output end of the second drive device, a belt sleeved on the outside of the rotating shaft, a drive column sleeved on one end of the belt, a connecting column fixedly connected to one side of the drive column, a gear fixedly connected to the outside of the connecting column, a drive roller fixedly connected to one end of the connecting column, two fixed plates fixedly connected to the top of the base plate, a roller rotatably connected between the two fixed plates, a top plate fixedly connected to the top of the fixed plates, a fixed rod fixedly connected to the bottom of the top plate, a gear rotatably connected to the bottom of the fixed rod, a fan fixedly connected to one side of the gear 2, and four support pillars fixedly connected to the bottom of the top plate.

[0007] As a further description of the above technical solution: a drive device is fixedly connected inside the placement box, an abutment rod is fixedly connected to the output end of the drive device, two connecting rods are fixedly connected to the bottom of the top plate, a roller is rotatably connected between the two connecting rods, and a hammer is rotatably connected to the bottom of the connecting rod.

[0008] As a further description of the above technical solution: the two pillars on one side are externally connected by a sliding cylinder, the sliding cylinder is externally fixedly connected to a mounting shell, the mounting shell is internally rotatably connected to a limit plate, and the mounting shell is internally rotatably connected to a rotating buckle.

[0009] As a further description of the above technical solution: the first gear meshes with the second gear.

[0010] As a further description of the above technical solution: the drive roller is rotatably connected between the two fixed plates.

[0011] As a further description of the above technical solution: the bottom of the support column is fixedly connected to the top of the base plate.

[0012] As a further description of the above technical solution: the abutting rod abuts against the hammer.

[0013] As a further description of the above technical solution: the rotating buckle passes through the limiting plate, and the insertion rod of the limiting plate is slidably connected inside the support column.

[0014] This utility model has the following beneficial effects: 1. In this utility model, the output end of the drive device drives the abutment rod to rotate, so that the abutment rod continuously hits the hammer. The hammer, through its lateral rotation, forms a knocking vibration on the surface of the line below the roller, thereby knocking off the formed ice and avoiding the accumulation of ice that could cause safety hazards.

[0015] 2. In this utility model, the gear one on the connecting column meshes with the gear two at the bottom of the fixing rod. When the gear two rotates, it drives the fan to rotate, generating airflow that blows onto the surface of the line, thus blowing away the water droplets and residual snow adhering to the line and preventing secondary icing.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figures 1-3This utility model provides an embodiment of a power transmission line antifreeze device, comprising a base plate 1, a placement box 2 fixedly connected to the bottom of the base plate 1, a drive device 4 fixedly connected inside the placement box 2, the drive device 4 being the core power source, a rotating shaft 5 fixedly connected to the output end of the drive device 4, the output end of the drive device 4 driving the rotating shaft 5 to rotate, a belt 6 sleeved on the outside of the rotating shaft 5, transmitting power to a drive column 7 through the belt 6, a drive column 7 sleeved on one end of the belt 6, a connecting column 8 fixedly connected to one side of the drive column 7, the drive column 7 causing the connecting column 8 to rotate synchronously, a gear 11 fixedly connected to the outside of the connecting column 8, and a drive wheel 9 fixedly connected to one end of the connecting column 8, the connecting column 8 causing the drive wheel 9 to rotate synchronously. The driving wheel 9 rotates, and two fixed plates 25 are fixedly connected to the top of the base plate 1. A roller 10 is rotatably connected between the two fixed plates 25. The fixed plates 25 fix the position of the roller 10 and the driving wheel 9. A top plate 15 is fixedly connected to the top of the fixed plate 25. A fixed rod 14 is fixedly connected to the bottom of the top plate 15. A gear 12 is rotatably connected to the bottom of the fixed rod 14. Gear 11 meshes with gear 12 at the bottom of the fixed rod 14. A fan 13 is fixedly connected to one side of gear 12. When gear 12 rotates, it drives the fan 13 to rotate. Four pillars 20 are fixedly connected to the bottom of the top plate 15. The top plate 15 is connected to the base plate 1 through the fixed plates 25. The four pillars 20 further enhance the overall structural stability.

[0020] Reference Figures 1-3 Inside the placement box 2, a drive device 3 is fixedly connected. The output end of the drive device 3 is fixedly connected to a stop rod 19, which drives the stop rod 19 to rotate. Two connecting rods 16 are fixedly connected to the bottom of the top plate 15. The connecting rods 16 support roller 17 and hammer 18. Roller 17 is rotatably connected between the two connecting rods 16. Roller 17 can rotate along the line. Hammer 18 is rotatably connected to the bottom of the connecting rods 16. The hammer 18 rotates laterally and forms a knocking vibration on the surface of the line below roller 17, knocking off the ice that has formed and preventing it from accumulating.

[0021] Reference Figures 1-3 The two pillars 20 on one side are externally connected to a sliding cylinder 21, which drives the mounting shell 22 to adjust its height. The sliding cylinder 21 is externally fixedly connected to the mounting shell 22. The mounting shell 22 is internally rotatably connected to a limiting plate 23. When the limiting plate 23 rotates, its insert rod can be inserted into the preset hole of the pillar 20 to fix the top plate 15 and the bottom plate 1 so that the device can operate stably. The mounting shell 22 is internally rotatably connected to a rotating buckle 24, which can fix the limiting plate 23.

[0022] Reference Figures 1-3Gear 11 meshes with gear 2 12 to achieve power transmission. When the connecting column 8 rotates, gear 11 synchronously drives gear 2 12 to rotate, so that the fan 13 can obtain power. The purging function can be realized without an additional drive source, simplifying the structure and saving energy.

[0023] Reference Figure 3 The drive wheel 9 is rotatably connected between two fixed plates 25. The fixed plates 25 provide stable support for the drive wheel 9, ensuring that its axis is fixed when it rotates. It works with the roller 10 to form a stable clamping and moving structure, ensuring that the device moves smoothly along the line.

[0024] Reference Figures 1-3 The bottom of the support column 20 is fixedly connected to the top of the base plate 1 to stabilize the device.

[0025] Reference Figures 1-3 The abutting rod 19 abuts against the hammer 18, so that the power of the drive device 3 is directly transmitted to the hammer 18 through the abutting rod 19, ensuring that the hammer 18 can effectively receive force and drive the roller 17 to swing, so as to realize the knocking and de-icing action.

[0026] Reference Figures 4-6 The rotating buckle 24 passes through the limiting plate 23. The insertion rod of the limiting plate 23 is slidably connected inside the support column 20. When the insertion rod of the limiting plate 23 is inserted into the support column 20, rotating the rotating buckle 24 can fix the limiting plate 23, thereby fixing the sliding cylinder 21.

[0027] Working principle: After the drive device 2 4 is started, the rotating shaft 5 at its output end drives the drive column 7 to rotate via the belt 6, which in turn causes the connecting column 8 and the drive roller at its end to rotate. The drive roller engages with the roller 10 between the drive roller and the fixed plate 25, generating the power to move along the transmission line, driving the entire device to travel on the conductor and expanding the working range. At the same time, the gear 11 on the connecting column 8 meshes with the gear 12 at the bottom of the fixed rod 14. When the gear 12 rotates, it drives the fan 13 to rotate, generating airflow that blows towards the surface of the line, which can disperse attached moisture and residual snow, thus improving subsequent work.

[0028] After the drive device 3 is started, the abutment rod 19 at its output end reciprocates and continuously strikes the hammer 18. The hammer 18 forms a knocking vibration on the surface of the line below the roller 17 by rotating laterally, knocking off the ice that has formed and preventing its accumulation. In addition, the sliding cylinder outside the support 20 can drive the mounting shell 22 and the internal limiting plate 23 and rotating buckle 24 to adjust their positions. The limiting plate 23 is fixed by the rotating buckle 24. The insertion rod of the limiting plate 23 is inserted into the support 20 to ensure that the device fits stably with the line and prevents it from shifting during operation. The insertion rod of the limiting plate 23 is pulled out and the sliding cylinder is moved upward to remove the device from the line.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
