Description

Technical Field

[0001] This utility model relates to the technical field of high-voltage power transmission, specifically to an overhead line de-icing device that does not require power outage. Background Technology

[0002] Freezing rain or icy weather, along with widespread rain and snow, has damaged power transmission lines in many areas, causing multiple main transmission lines to break down and trip. Ensuring the stable operation of the power system has become the primary concern for outdoor power transmission lines under extreme weather conditions.

[0003] When laying overhead lines, a support frame needs to be installed first. The support frame is then erected, and the conductors are installed on the support frame through insulators. High-altitude power transmission is achieved through the support frame. In winter, due to the low temperature, the conductors on the overhead lines are prone to icing. Icing on the overhead distribution lines in operation can cause the overhead lines to exceed the designed load, resulting in accidents such as insufficient sag to the ground, damage to hardware or insulators, broken lines, and pole collapse. Summary of the Invention

[0004] The purpose of this invention is to provide an overhead line de-icing device that does not require power outages, in order to solve the aforementioned defects caused by the prior art.

[0005] An overhead power line uninterrupted de-icing device includes a support frame body and an outer casing assembly. Wire brackets are symmetrically arranged on the outer side of the support frame body. The outer casing assembly is also arranged on the outer side of the outer casing assembly, and an adjustment mechanism is provided on the outer side of the outer casing assembly. The adjustment mechanism adjusts the position of the device according to usage requirements, and further adjusts the height of the outer casing assembly according to the de-icing needs and the position of the wire brackets. De-icing mechanisms are arranged on both the left and right sides of the outer casing assembly. These de-icing mechanisms strike the surface of the overhead power lines on both sides. By controlling the striking distance, the force of ice removal is controlled.

[0006] Preferably, the adjusting mechanism includes an outer sleeve assembly, a guide groove, a fastening hole, and a rubber guide rod. The outer side of the outer sleeve assembly is connected to the guide groove, and both the outer sleeve assembly and the outer side of the support frame body are provided with fastening holes. The outer side of the outer sleeve assembly is rectangularly connected to the rubber guide rod, and the bottom end of the rubber guide rod is connected to the interior of the support frame body.

[0007] Preferably, the support frame body is connected to the outer side of the outer casing assembly through a guide groove on the outer side.

[0008] Preferably, the de-icing mechanism includes a side control box, a motor, a de-icing shovel, a positioning arm one, a positioning arm two, and an eccentric wheel. The motor is connected to the outside of the side control box, and the output end of the motor is connected to the eccentric wheel. Positioning arms one are connected to both the upper and lower sides of the eccentric wheel. One end of positioning arm two is connected through the outside of positioning arm one, and the other end of positioning arm two is connected to the top of the de-icing shovel.

[0009] Preferably, the side control box is connected to the outside of the support frame body via an outer sleeve assembly connected to one side.

[0010] Preferably, the side control box is connected to the outer side of the positioning arm two through a through guide slot.

[0011] Preferably, a parallel reactor is provided on one side of the interior of the side control box.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. By connecting a reactor or isolation transformer in parallel on a 35kV line and using the principle of carrier communication, DC current or high-frequency AC current is added to the 35kV line. By utilizing the resistance and reactance of the line itself, the transmission line can operate in a steady state for several hours, thereby heating the steel-cored aluminum stranded wire, causing the frost and ice on the line surface to melt and fall off, achieving the purpose of de-icing without power interruption.

[0014] 2. During use, by pulling the second positioning arm, the unfolded position of the second positioning arm can be adjusted, which facilitates the auxiliary de-icing of the wires on the upper and lower sides. The motor drives the eccentric wheel to rotate, which in turn drives the first positioning arm on the upper and lower sides to move up and down frequently, which facilitates the vibration and removal of ice attached to the surface of the wires.

[0023] like Figures 1 to 5 As shown, an overhead power line uninterrupted de-icing device includes a support frame body 1 and an outer casing assembly 3. Wire brackets 2 are symmetrically arranged on the outer side of the support frame body 1, and the outer casing assembly 3 is also arranged on the outer side of the outer casing assembly 3. An adjusting mechanism 5 is provided on the outer side of the outer casing assembly 3. The adjusting mechanism 5 adjusts the position of the device according to usage requirements, and further adjusts the height of the outer casing assembly 3 according to the de-icing requirements and the position of the wire brackets 2. De-icing mechanisms 7 are provided on both the left and right sides of the outer casing assembly 3. The de-icing mechanisms 7 strike the surface of the overhead power lines on both sides, and the force of ice removal is controlled by controlling the striking distance.

[0024] In this embodiment, the adjusting mechanism 5 includes an outer sleeve assembly 3, a guide groove 4, a fastening hole 6, and a rubber guide rod 12. The outer side of the outer sleeve assembly 3 is connected to the guide groove 4. The outer sleeve assembly 3 and the support frame body 1 are both provided with fastening holes 6 on their outer sides. The outer side of the outer sleeve assembly 3 is rectangularly connected to the rubber guide rod 12. The bottom end of the rubber guide rod 12 is connected to the interior of the support frame body 1.

[0025] In this embodiment, the support frame body 1 is connected to the outer side of the outer jacket assembly 3 through a guide groove 4 on the outer side. The guide groove 4 positions and guides the outer side of the outer jacket assembly 3 to prevent the outer jacket assembly 3 from shifting.

[0026] In this embodiment, the de-icing mechanism 7 includes a side control box 8, a motor 9, a de-icing shovel body 10, a first positioning arm 13, a second positioning arm 14, and an eccentric wheel 15. The motor 9 is connected to the outside of the side control box 8, and the output end of the motor 9 is connected to the eccentric wheel 15. The first positioning arm 13 is connected to both the upper and lower sides of the eccentric wheel 15. One end of the second positioning arm 14 is connected through the outside of the first positioning arm 13, and the other end of the second positioning arm 14 is connected to the top of the de-icing shovel body 10. The eccentric wheel 15 is driven by the motor 9.

[0027] In this embodiment, the side control box 8 is connected to the outside of the support frame body 1 through the outer jacket assembly 3 connected on one side, and the wires are de-iced by applying pressure through the symmetrically arranged side control boxes 8.

[0028] In this embodiment, the side control box 8 is connected to the outside of the positioning arm 2 14 through the through guide groove 11. The guide groove 11 is used to position and guide the outside of the outer casing assembly 3, and the outer casing assembly 3 is positioned according to the spacing of the wire bracket 2.

[0029] In practical applications, this type of overhead line uninterrupted de-icing device includes the following tasks:

[0030] Step 1: The operator first installs the wire bracket 2 on the outside of the support frame body 1, and locks the wire bracket 2 to the support frame body 1 with bolts. Then, the operator pulls the outer sleeve assembly 3 so that the outer sleeve assembly 3 slides on the outside of the support frame body 1 to adjust the height of the side control boxes 8 on both sides. At the same time, the rubber guide rod 12 is used to guide the inside of the outer sleeve assembly 3 to prevent the guide groove 4 from nesting the outer sleeve assembly 3 during the lifting and lowering process. The operator then locks the fastening hole 6 and the outer sleeve assembly 3 with bolts.

[0031] Step 2: Under extreme weather conditions such as blizzards and freezing rain, a reactor 16 is connected in parallel on the 35kV line. Using the principle of carrier communication, a DC current or high-frequency AC current is added to the 35kV line. By utilizing the resistance and reactance of the line itself, the transmission line can operate in a steady state for several hours, thereby heating the steel-cored aluminum stranded wire, causing the frost and ice on the line surface to melt and fall off, achieving the purpose of de-icing without power interruption.

[0032] Step 3: At the same time, the motor 9 can be turned on, and the eccentric wheel 15 can be rotated by the motor 9. The eccentric wheel 15 can be used to push the bottom end of the positioning arm 13. The positioning arm 13 can be used to drive the positioning arm 2 14 to move vertically upward. The positioning arm 13 and the positioning arm 2 14 can be used to repeatedly push the surface of the wire, and the wire on the outside of the de-icing shovel body 10 can be used to push, which can accelerate the speed at which the ice falls off the surface of the wire after it has melted.

[0033] Therefore, the above-disclosed embodiments are merely illustrative in all respects and are not the only ones. All modifications within the scope of this utility model or its equivalents are included in this utility model.
