Description

Technical Field

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

[0002] Transmission and transformation lines are important facilities for transmitting and distributing electric energy in power systems. They connect power plants with load centers, such as cities and industrial areas, to ensure that electricity can be efficiently and safely transmitted from the production end to the user end. According to their functions, transmission and transformation lines can be divided into two categories: transmission lines and distribution lines. Regardless of the type of wire, they all need to transmit electric energy over long distances outdoors. Therefore, in the winter snow season, the outer wall of the wire will be wrapped in a layer of ice. In order to reduce the load-bearing burden of the wire, workers are required to de-ice it.

[0003] In the prior art, there are many ways to de-ice electric wires. The most common method is to knock on the outer wall of the wire to break and shake off the ice on the outer wall of the wire. The method can be manual knocking or de-icing by a de-icing device. However, when the ice on the outer wall of the wire is thick, a simple knocking action is difficult to complete the de-icing work, and the violent knocking force will also cause the wire to bear a large impact force. On the one hand, it is difficult to ensure the de-icing efficiency, and on the other hand, there is a risk of damaging the wire. Summary of the invention

[0016] Compared with the prior art, the present invention provides a deicing device for power transmission and transformation lines, which has the following beneficial effects:

[0017] 1. The deicing device for power transmission and transformation lines starts a driving motor to drive the roller to move along the wire, and the cutting machines on both sides drive the cutting disc to cut the ice, and the cutting force of the cutting disc mainly acts on both sides of the ice, so that the damage to the wire can be effectively reduced. After cutting, the ice will automatically fall down, and the moving roller will press down and vibrate the ice, so that the ice will fall down more easily, and the deicing work of the wire can be completed efficiently.

[0018] 2. The deicing device for power transmission and transformation lines drives the horizontal axis and the two first reciprocating screws to rotate through the opening and closing motor, and the two cutting discs will open and close, thereby preventing the cutting discs from being stuck by ice cubes, so as to improve the efficiency of the cutting discs in cutting ice cubes. The cutting discs close to each other will drive the conical boss to press the gaps produced by cutting, so that the ice cubes will break from the gaps, which can further improve the deicing efficiency.

[0019] 3. The deicing device for power transmission and transformation lines drives the second reciprocating screw to rotate continuously through the reciprocating motor, and the long axis drives the knocking rod to swing back and forth. The knocking rod knocks on both sides of the wire in turn, so that the cut ice can fall off the wire faster, significantly improving the deicing efficiency of the wire.

[0020] 4. When the deicing device for power transmission and transformation lines squeezes the retractable airbag through the slide, the vertical pipe will blow air to the deiced wires through the airflow nozzle to blow off the remaining broken ice on the wires and improve the deicing effect, while the arc tube will spray antifreeze to the deiced wires through the liquid nozzle so that the outer wall of the wire is wetted by the antifreeze, which can make the deiced wires less likely to freeze again.

[0021] 5. The deicing device for power transmission and transformation lines can collect ice cubes dropped during the deicing process through a collection box, which can increase the counterweight of the collection box, making the entire device more stable when moving and reducing the impact of natural wind.

[0022] 6. The deicing device for power transmission and transformation lines can crush the ice in the collection box by driving the crushing roller to rotate through the crushing motor. The crushed powder will be discharged from the collection box from the discharge port, so the weight of the entire device can be effectively controlled. Moreover, when the crushed debris falls downward, it is not easy to cause harm to the environment and people under the wires, and the deicing process will be safer. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0034] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0035] Embodiment 1:

[0036] Reference Figure 1-Figure 9 A deicing device for power transmission and transformation lines comprises a frame 1, and also comprises: an outer cover 5 which plays a protective role and is fixedly connected to the lower end of the frame 1, wherein two symmetrical cutters 6 are installed in the outer cover 5, a gap is provided between the two cutters 6, the width of the gap is greater than the diameter of the wire, an opening and closing part is provided in the outer cover 5 for driving the two cutters 6 to approach and move away indirectly, a moving part for driving the translation is provided on the frame 1, and the moving part is used to move the frame 1 along the wire, the moving part comprises a roller 2 which is rotatably connected to the lower end of the frame 1, the roller 2 is made of wear-resistant rubber, an annular groove 3 is provided on the outer wall of the roller 2, and an anti-slip pattern is provided on the inner wall of the annular groove 3, and a driving motor 4 for driving the roller 2 to rotate is fixedly installed on the frame 1; a collecting box 14 with a discharge port 35 at the bottom is fixedly connected to the lower end of the frame 1 through an L-shaped plate 13, the collecting box 14 is used to collect ice cubes produced by cutting the cutter 6, and a crushing component for crushing ice cubes is provided in the discharge port 35.

[0037] Specifically, when in use, the annular groove 3 of the roller 2 is buckled on the outer wall of the wire so that the entire device is suspended on the wire through the roller 2. At this time, the two cutters 6 will be located exactly on both sides of the wire, and then the entire device is started. The driving motor 4 will drive the roller 2 to move along the wire, and the cutters 6 on both sides will cut the ice. As the frame 1 continues to move, the cutters 6 on both sides will cut openings on both sides of the ice on the wire. During cutting, the cutting force of the cutter 6 mainly acts on both sides of the ice, so that the damage to the wire can be effectively reduced. After cutting, the ice will automatically fall down, and the moving roller 2 will press down and vibrate the ice, so that the ice can fall more easily, and the de-icing of the wire can be efficiently completed.

[0038] In practice, in order to enable the entire device to complete the deicing work in either direction, the cutter 6 can be installed on both sides of the frame 1, that is, two groups of symmetrically arranged deicing components can be set on the frame 1, and batteries need to be installed to power the entire device.

[0039] The above-mentioned crushing components include two rotating rods 37 rotatably installed in the discharge port 35, and the outer walls of the two rotating rods 37 are fixedly installed with crushing rollers 36. The outer walls of the crushing rollers 36 are in the shape of gears, and the gear teeth of the two crushing rollers 36 are meshed with each other. The two rotating rods 37 are connected by two mutually meshing transmission gears 38, and the outer wall of the collection box 14 is fixedly installed with a crushing motor 39 that drives one of the rotating rods 37 to rotate.

[0040] During the de-icing process, the fallen ice cubes will be retained in the collection box 14, which can increase the counterweight of the collection box 14, making the entire device more stable when moving and reducing the impact of natural wind. When there are more ice cubes in the collection box 14, the crushing motor 39 is started, and the crushing motor 39 will drive one of the rotating rods 37 to rotate. The current rotating rod 37 will drive the other rotating rod 37 to rotate synchronously under the action of two mutually meshing transmission gears 38, and the two rotating rotating rods 37 will drive the two crushing rollers 36 to rotate synchronously, so that the ice cubes in the collection box 14 can be crushed, and the crushed powder will be discharged from the collection box 14 from the discharge port 35, so that the counterweight of the entire device can be effectively controlled, and the crushed debris will not easily cause damage to the environment and people under the wires when falling downwards, and the de-icing process will be safer.

[0041] A lifting device 40 is fixedly installed on the side of the collection box 14 away from the L-shaped plate 13. The lifting device 40 can be an electric telescopic rod. The telescopic end of the lifting device 40 is fixedly connected with an active magnet 41. A driven magnet 42 attracted to the active magnet 41 is fixedly connected to the frame 1. The active magnet 41 and the driven magnet 42 are both made of permanent magnets.

[0042] Specifically, since the frame 1 fixes the collection box 14 through the L-shaped plate 13, it is mainly for the convenience of clamping the wires into the annular groove 3. Therefore, when in use, the center of the entire device will tilt to one side. At this time, the active magnet 41 is driven to move upward by the lifting device 40 until the active magnet 41 absorbs the driven magnet 42. Then, both sides of the collection box 14 can be connected to the collection box 14, which can make the entire device less likely to tilt to one side and more stable during the de-icing process.

[0043] Embodiment 2:

[0044] Reference Figure 5-Figure 7 , which is basically the same as the first embodiment, and further discloses a specific implementation scheme of the opening and closing part.

[0045] The above-mentioned opening and closing part includes a transverse axis 9 rotatably connected to the outer cover 5, and both ends of the transverse axis 9 are fixedly connected to a first reciprocating screw 10, wherein the outer walls of the two first reciprocating screws 10 are threadedly connected to a slider 12 slidably connected to the inner wall of the outer cover 5, and the two cutting machines 6 are respectively fixedly installed on the two sliders 12, and the outer wall of the outer cover 5 is fixedly installed with an opening and closing motor 11 for driving the transverse axis 9 to rotate. When the first reciprocating screw 10 continues to rotate, the slider 12 can slide back and forth along the outer wall of the first reciprocating screw 10, and the output end of the cutting machine 6 is fixedly installed with a cutting disk 7 with a thin sheet shape. The material of the cutting disk 7 can be selected from a fiber-reinforced composite material, plastic or soft metal cutting blade with a hardness less than that of an electric wire, and the axial end of the cutting disk 7 is fixedly connected with a conical boss 8.

[0046] Specifically, during de-icing, the opening and closing motor 11 will drive the horizontal axis 9 and the two first reciprocating screws 10 to rotate, and the two sliders 12 will slide back and forth along the outer walls of the two first reciprocating screws 10, respectively, thereby driving the two cutters 6 and the cutting disk 7 to open and close, that is, indirectly approaching and moving away, thereby preventing the cutting disk 7 from being stuck by the ice, so as to improve the efficiency of the cutting disk 7 in cutting the ice, and the cutting disks 7 approaching each other will drive the conical boss 8 to press the gap produced by the cutting, so that the ice will break from the gap, which can further improve the de-icing efficiency. Even if the cutting disk 7 does not completely cut through the ice to protect the wires, the ice will automatically break through.

[0047] Embodiment three:

[0048] Reference Figure 4-Figure 5 as well as Figure 8-Figure 9 , which is basically the same as the second embodiment, and further, a specific implementation plan for improving deicing efficiency is specifically added.

[0049] The inner top of the above-mentioned collection box 14 is fixedly connected with a device box 15, and a long shaft 16 is rotatably connected to the device box 15. When in use, the long shaft 16 will be basically parallel to the wire, and a spring 17 is fixedly installed at the end of the long shaft 16. The free end of the spring 17 is fixedly connected to a knocking rod 18 for knocking the outer wall of the wire. A reciprocating part for driving the long shaft 16 to reciprocate is provided in the device box 15, and the reciprocating part includes a second reciprocating screw 20 rotatably connected in the device box 15, and the outer wall of the second reciprocating screw 20 is threadedly connected to a slide 22 slidably connected to the inner wall of the device box 15, and a rack 23 is fixedly installed on the slide 22. When the long shaft 16 is fixedly installed, there is a driven gear 24 meshing with the rack 23, and a reciprocating motor 21 for driving the second reciprocating screw 20 to rotate is fixedly installed on the outer wall of the device box 15

[0050] Specifically, during de-icing, the reciprocating motor 21 is started, and the reciprocating motor 21 will drive the second reciprocating screw 20 to rotate continuously, and the second reciprocating screw 20 will drive the slide 22 to slide back and forth, and the slide 22 will drive the rack 23 to slide back and forth, and the rack 23 will drive the driven gear 24 to rotate back and forth, and the driven gear 24 will drive the long shaft 16 to rotate back and forth, and the long shaft 16 will drive the knocking rod 18 to swing back and forth through the spring 17, and the reciprocatingly swinging knocking rod 18 will knock on both sides of the wire in turn, so that the cut ice cubes can fall off the wire faster, and the de-icing efficiency of the wire is significantly improved. During the knocking period, the spring 17 can prevent the knocking rod 18 from having too much impact force on the wire, so as to protect the wire. Since the ice cubes have been cut into gaps by the cutting disk 7, the knocking rod 18 with a small force can also knock off the ice cubes.

[0051] Similarly, in order to enable the entire device to complete the de-icing work in either direction, knocking rods 18 can be installed at both ends of the long axis 16 to cooperate with the two sets of cutting machines 6 to complete the de-icing work. In order to improve the de-icing efficiency of the knocking rod 18, a protruding ring 19 can also be fixed on the outer wall of the knocking rod 18 to increase the friction between the knocking rod 18 and the ice.

[0052] Embodiment 4:

[0053] Reference Figure 4-Figure 5 as well as Figure 7 -and Fig. 9 , which is basically the same as the third embodiment, and further, a specific implementation plan for antifreezing the electric wires is specifically added.

[0054] The bottom of the frame 1 is fixedly connected with a vertical pipe 26 and an arc tube 29 in sequence. The lower ends of the vertical pipe 26 and the arc tube 29 are respectively fixedly installed with an air flow nozzle 27 and a liquid nozzle 30. The air flow nozzle 27 is used to blow air to the surface of the wire, and the liquid nozzle 30 is used to spray antifreeze or antifreeze agent to the surface of the wire. The air flow nozzle 27 is located between the liquid nozzle 30 and the cutting machine 6. The inner bottom of the device box 15 is provided with a storage chamber 25, which is used to store antifreeze or antifreeze, and is provided with a liquid filling port that can be sealed and opened. The liquid filling port Not shown in the figure, the arc tube 29 is fixedly connected with a drain pipe 31 extending to the bottom of the storage chamber 25, and the vertical pipe 26 is fixedly connected with an air pipe 28 extending to the top of the storage chamber 25. The device box 15 is provided with a booster for pressurizing the storage chamber 25, and the booster includes a telescopic air bag 32 fixedly installed between the slide 22 and the inner wall of the device box 15, and the telescopic air bag 32 is fixedly connected with an air intake pipe 33 and an exhaust pipe 34, and the air intake pipe 33 and the exhaust pipe 34 are fixedly installed with a one-way valve, and the end of the exhaust pipe 34 extends to the storage chamber 25.

[0055] Specifically, when the slide 22 slides back and forth, the slide 22 will indirectly squeeze and stretch the telescopic airbag 32. When the telescopic airbag 32 is stretched, it will absorb external air through the intake pipe 33. When the telescopic airbag 32 is squeezed, air will be transported to the storage chamber 25 through the exhaust pipe 34. The air pressure in the storage chamber 25 will increase, so the excess gas will be transported to the vertical pipe 26 through the air supply pipe 28. The vertical pipe 26 will blow air to the deiced wires through the air flow nozzle 27 to blow off the remaining broken ice on the wires, thereby improving the deicing effect. When the air flow nozzle 27 is directed toward the knocking rod 18 at the same time, the knocking rod 18 can be cleaned, and the air pressure of another part of the storage chamber 25 will transport the antifreeze inside it to the arc tube 29 through the drain pipe 31. The arc tube 29 will spray the antifreeze to the deiced wires through the liquid nozzle 30, so that the outer wall of the wire is wetted by the antifreeze, which can make the deiced wires less likely to freeze again.

[0056] Similarly, in order to enable the entire device to complete the deicing work in any direction, the air flow nozzles 27 can also be provided in two groups symmetrically on the left and right, and the liquid nozzles 30 only need to be provided in one group in the middle of the frame 1.

[0057] The deicing device for power transmission and transformation lines is used by buckling the annular groove 3 of the roller 2 on the outer wall of the wire so that the whole device is suspended on the wire through the roller 2. At this time, the two cutting discs 7 will be just located on both sides of the wire. Then the whole device is started, the driving motor 4 will drive the roller 2 to move along the wire, and the cutters 6 on both sides will drive the cutting discs 7 to cut the ice. As the frame 1 keeps moving, the cutting discs 7 on both sides will cut openings on both sides of the ice on the wire. During cutting, the cutting force of the cutting discs 7 mainly acts on both sides of the ice, so that the damage to the wire can be effectively reduced. After cutting, the ice will automatically fall down, and the moving roller 2 will press down and vibrate the ice, so that the ice can fall down more easily, and the deicing work of the wire can be completed efficiently.

[0058] During de-icing, the opening and closing motor 11 will drive the horizontal axis 9 and the two first reciprocating screws 10 to rotate, and the two sliders 12 will slide back and forth along the outer walls of the two first reciprocating screws 10 respectively, thereby driving the two cutters 6 and the cutting disk 7 to open and close, that is, indirectly approaching and moving away, thereby preventing the cutting disk 7 from being stuck by the ice, so as to improve the efficiency of the cutting disk 7 in cutting the ice, and the cutting disks 7 approaching each other will drive the conical boss 8 to press the gap produced by the cutting, so that the ice will break from the gap, which can further improve the de-icing efficiency. Even if the cutting disk 7 does not completely cut through the ice to protect the wires, the ice will automatically break through.

[0059] During de-icing, the reciprocating motor 21 is started, and the reciprocating motor 21 will drive the second reciprocating screw 20 to rotate continuously, and the second reciprocating screw 20 will drive the slide 22 to slide back and forth, and the slide 22 will drive the rack 23 to slide back and forth, and the rack 23 will drive the driven gear 24 to rotate back and forth, and the driven gear 24 will drive the long shaft 16 to rotate back and forth, and the long shaft 16 will drive the knocking rod 18 to swing back and forth through the spring 17, and the reciprocatingly swinging knocking rod 18 will knock on both sides of the wire in turn, so that the cut ice cubes can fall off the wire faster, and the de-icing efficiency of the wire is significantly improved. During the knocking period, the spring 17 can prevent the knocking rod 18 from having too much impact force on the wire, so as to protect the wire. Since the ice cubes have been cut into gaps by the cutting disk 7, the knocking rod 18 with a small force can also knock off the ice cubes.

[0060] When the slide 22 slides back and forth, the slide 22 will indirectly squeeze and stretch the telescopic airbag 32. When the telescopic airbag 32 is stretched, it will absorb external air through the intake pipe 33. When the telescopic airbag 32 is squeezed, air will be transported to the storage chamber 25 through the exhaust pipe 34. The air pressure in the storage chamber 25 will increase, so the excess gas will be transported to the vertical pipe 26 through the air supply pipe 28. The vertical pipe 26 will blow air to the deiced wires through the air flow nozzle 27 to blow off the remaining broken ice on the wires, thereby improving the deicing effect. The air pressure of another part of the storage chamber 25 will cause the antifreeze inside the storage chamber 25 to be transported to the arc tube 29 through the drain pipe 31. The arc tube 29 will spray the antifreeze to the deiced wires through the liquid nozzle 30, so that the outer wall of the wire is wetted by the antifreeze, which can make the deiced wires less likely to freeze again.

[0061] During the de-icing process, the fallen ice cubes will be retained in the collection box 14, which can increase the counterweight of the collection box 14, making the entire device more stable when moving and reducing the impact of natural wind. When there are more ice cubes in the collection box 14, the crushing motor 39 is started, and the crushing motor 39 will drive one of the rotating rods 37 to rotate. The current rotating rod 37 will drive the other rotating rod 37 to rotate synchronously under the action of two mutually meshing transmission gears 38, and the two rotating rotating rods 37 will drive the two crushing rollers 36 to rotate synchronously, so that the ice cubes in the collection box 14 can be crushed, and the crushed powder will be discharged from the collection box 14 from the discharge port 35, so that the counterweight of the entire device can be effectively controlled, and the crushed debris will not easily cause damage to the environment and people under the wires when falling downwards, and the de-icing process will be safer.

[0062] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
