Description
Technical Field
[0001] This invention relates to the field of high-voltage transmission line technology, specifically to a de-icing device for high-voltage transmission cables. Background Technology
[0002] High-voltage power transmission is a method of transmitting electricity by stepping up the voltage output from generators using transformers at power plants. To solve the problem of power shortages, many ultra-high-voltage transmission lines have been built through the West-to-East Power Transmission Project. The biggest threat to transmission lines is icing and snow accumulation. Icing and snow accumulation increase the weight of transmission lines and damage them, so personnel are needed to inspect transmission lines and carry out de-icing and snow removal.
[0003] There are currently three main methods of de-icing: one is manual de-icing, which involves sending power workers to knock down the accumulated ice with wooden sticks. This method is inefficient, has great limitations, and is very dangerous.
[0004] The second method is short-circuit de-icing, which involves short-circuiting the circuit momentarily to generate heat and remove ice. However, this method inevitably leads to power outages and consumes a lot of energy, but the effect is not ideal.
[0005] Thirdly, there is mechanical de-icing, which involves using unmanned de-icing machinery to be positioned on the high-voltage transmission cable for mechanical knocking and de-icing. However, this method is only suitable for single high-voltage transmission cables or parallel double cables. In high-voltage transmission projects, split conductors are common, meaning that each phase conductor consists of several smaller diameter sub-conductors, which are spaced a certain distance apart and arranged in a symmetrical polygonal pattern. Existing mechanical de-icing methods cannot effectively de-ic the split conductors. Summary of the Invention

[0020] Compared with the prior art, the beneficial effects of the present invention are:
[0021] 1. This invention achieves the binding of the split conductor group by moving the first binding chain assembly upward, reducing the closed loop formed between the first binding chain assembly, the second binding chain assembly, and the fixed seat. Then, the first binding chain assembly, the second binding chain assembly, and the fixed seat continuously tighten and loosen the split conductor group, thereby changing the degree of bending of the split conductor. Since ice cannot be bent, when the split conductor bends, it will break and fall downward, thus achieving the purpose of effectively de-icing the split conductor group.
[0022] 2. This invention also incorporates two auxiliary shafts, with the line connecting the center of the drive shaft and the two auxiliary shafts forming an equilateral triangle. This allows the drive arm to rotate when the drive shaft rotates, causing the movable plate to move and creating a spring-loaded walking mechanism. The movable plate, in conjunction with the connecting plate, movable groove, and movable rod, moves in a regular arc motion. This arc motion causes the walking plate to collide with the branch conductor, generating vibrations. These vibrations are mutual, allowing the walking plate to transmit the vibrations through the walking frame, motor bracket, mounting plate, and fixed seat to the first and second restraint chain assemblies. This, in turn, causes the walking plate, along with the first and second restraint chain assemblies, to simultaneously vibrate the branch conductor, dislodging ice from its surface and further achieving a de-icing effect.

[0037] De-icing component 3 is disposed on the surface of the split conductor group and is used to bind the split conductor 1, causing the split conductor 1 to bend, thereby achieving the purpose of de-icing.

[0039] The drive component 7 is located on top of the de-icing component 3 and is used to drive the de-icing component 3 to continuously bind and loosen the branch wire 1. The drive component 7 is also used to drive the walking component 8 to work.
[0040] The de-icing assembly 3 includes a first opening and closing flap 31 and a second opening and closing flap 34. The top of the first opening and closing flap 31 and the second opening and closing flap 34 are respectively rotatably connected to a fixed shaft 5. The surfaces of the two fixed shafts 5 are fixedly mounted with fixed seats 4. The top of the fixed seats 4 is fixedly mounted with a support column 9, and the top of the support column 9 is fixedly mounted with a mounting plate 6. One end of the top of the first opening and closing flap 31 and the second opening and closing flap 34 is rotatably provided with an electric push rod 10. Both ends of the electric push rod 10 are fixedly mounted with sleeves, and the inner walls of the two sleeves are rotatably connected with support shafts. The two support shafts are respectively fixedly mounted at the same end of the top of the first opening and closing flap 31 and the second opening and closing flap 34.
[0041] The inner wall of the first opening and closing flap 31 is movably provided with a first restraining chain assembly 32. The first restraining chain assembly 32 includes a first chain head 321, a first chain tail 323, and a first connecting chain 322 rotatably connected between the first chain head 321 and the first chain tail 323 and rotatably rotating relative to each other. The first chain head 321, the first connecting chain 322, and the first chain tail 323 are arranged one after another from top to bottom. The first connecting chain 322 is movably connected to the top of the fixed base 4. A locking hook 324 is fixedly installed at one end of the first chain tail 323 corresponding to the position of the second opening and closing flap 34. A worm gear groove 325 is opened on the surface of the first connecting chain 322. A first magnet block 33 is fixedly embedded in the middle of the top of the first opening and closing flap 31.

The second chain head 351, the second connecting chain 352, and the second chain tail 353 are arranged sequentially from top to bottom. The second chain head 351 is fixedly installed at one end of the fixed base 4.

The metal plate 37 and the first magnet block 33 are located at one end of the top of the first opening and closing flap 31 because the first connecting chain 322 is relatively close to the worm gear 704. Through the cooperation of the first magnet block 33 and the magnetic metal plate 37, there is a large traction force, which allows the first connecting chain 322 at the corresponding position of the first magnet block 33 to maintain a close relationship with the first opening and closing flap 31, and also allows the first connecting chain 322 to move along the inner wall of the first opening and closing flap 31. By setting the second magnet block 36 in cooperation with the magnetic metal plate 37, the second connecting chain 352 can be attached to the inner wall of the second opening and closing flap 34, so that there is a long distance between the bottom of the first binding chain assembly 32 and the second binding chain assembly 35, which facilitates the wrapping of the split wire group by the first binding chain assembly 32 and the second binding chain assembly 35.
[0043] The drive assembly 7 includes a dual-axis motor 701, which is fixedly mounted on the top of the mounting plate 6.

A second transmission belt 713 is drivenly connected to the surface of the second transmission wheel 712, and a transmission shaft 714 is drivenly connected to one end of the second transmission belt 713 away from the second transmission wheel 712. A motor bracket 715 is fixedly mounted on the surface of the positive and negative dual-axis motor 701, and the motor bracket 715 is fixedly mounted on the top of the mounting plate 6.
[0046] The walking assembly 8 includes a walking frame 801, which is fixedly installed at one end of the motor bracket 715. The walking frame 801 is fixedly connected to one end of the fixed shaft 5, and the transmission shaft 714 is rotatably connected to the middle of the walking frame 801 through a bearing. Two auxiliary shafts 802 are rotatably connected to the middle of the walking frame 801 through a bearing. The line connecting the center of the transmission shaft 714 and the two auxiliary shafts 802 forms an equilateral triangle. A drive arm 803 is fixedly installed at one end of the transmission shaft 714 and the auxiliary shafts 802 respectively. There are six drive arms 803, and three drive arms 803 form a group. The two groups of drive arms 803 are respectively set at the front and rear ends of the walking frame 801. A movable plate 804 is rotatably connected to one end of each group of three drive arms 803.
[0047] A connecting plate 805 is fixedly installed at the bottom of the movable plate 804. A movable groove 806 is opened in the middle of the connecting plate 805.

The bottom of the walking plate 808 has multiple protrusions and the bottom of the walking plate 808 is rough. The walking plate 808 is movably connected to the top of the branch wire 1. A first crossbar 809 is fixedly installed at the top of two horizontally adjacent movable rods 807. A telescopic rod 810 is fixedly installed at the top of the first crossbar 809. A second damping spring 811 is fixedly installed on the surface of the telescopic rod 810. A second crossbar 812 is fixedly installed at the top of the telescopic rod 810 and is fixedly installed at one end of the connecting plate 805.
[0048] Working principle: In use, the invention first uses a drone to move the drive assembly 7 and the walking assembly 8 above the split wire group. In the initial position, the electric push rod 10 is in the retracted state, at which time the first opening and closing flap 31 and the second opening and closing flap 34 are in the open state. The first magnet block 33 and the second magnet block 36 cooperate with the magnetic metal plate 37 to make the distance between the bottom of the first binding chain assembly 32 and the first binding chain assembly 32 sufficiently wide. Then, the drone moves the drive assembly 7 and the walking assembly 8 downward until the fixed base 4 and the walking plate 808 are placed on the split wire 1. After that, the electric push rod 10 is energized and stretched to drive the first opening and closing flap 31 and the second opening and closing flap 34 into the closed state, thereby making the first binding chain assembly... When the bottoms of the first and second binding chain assemblies 32 and 35 approach each other, the electromagnet 355 is energized and attracts to the surface of the magnetic metal plate 37 in the middle of the first connecting chain 322. The dual-axis motor 701 is energized, and in conjunction with the first transmission belt 702, it drives the first transmission wheel 703 to rotate. This, in turn, causes the first transmission wheel 703 to drive the worm gear 704 to rotate. The worm gear 704 engages with the worm wheel groove 325, causing the first binding chain assembly 32 to move when it rotates. When the worm gear 704 rotates and moves the first binding chain assembly 32 upwards, the first chain tail 323 moves the locking hook 324 upwards. Because the electromagnet 355 is tightly attached to the first connecting chain 322... The surface of the magnetic metal plate 37 in the middle of the chain 322 is connected to the locking hook 324. This allows the locking hook 324 to move into the inner wall of the locking groove 354 when the locking hook 324 moves upward, thereby forming a closed loop between the first binding chain assembly 32, the second binding chain assembly 35, and the fixed base 4. As the dual-axis motor 701 continues to rotate, it, in conjunction with the first transmission belt 702, the first transmission wheel 703, and the worm gear 704, continues to drive the first binding chain assembly 32 upward, thereby reducing the closed loop formed between the first binding chain assembly 32, the second binding chain assembly 35, and the fixed base 4. This achieves the purpose of binding the split wire group. After the split conductor assembly is secured, the reciprocating rotation of the dual-axis motor 701 causes the first securing chain assembly 32, the second securing chain assembly 35, and the fixing base 4 to continuously tighten and loosen the split conductor assembly, thereby changing the curvature of the split conductor 1. Since ice cannot be bent, when the split conductor 1 bends, it will break and fall downwards, thus achieving the de-icing effect. This mechanism can also adapt to split conductor assemblies of different sizes. When the first securing chain assembly 32, the second securing chain assembly 35, and the fixing base 4 loosen the split conductor assembly, the walking assembly 8 can drive the de-icing assembly 3 to move via the drive assembly 7. This means that even the presence of conical ice shards and spacers 2 at the bottom of the split conductor 1 will not affect the forward movement of the device.This effectively achieves the purpose of de-icing the split conductor assembly. When the dual-axis motor 701 rotates continuously in both directions, when it rotates in the forward direction (driving the first restraining chain assembly 32 to tighten the split conductor assembly), the motor drives the ratchet 708 via the drive shaft 707. This causes the ratchet 708 to move the pawl 709 upwards, and the pawl 709 to move the fixing rod 710 upwards within the sleeve 711, compressing the first damping spring 716. Consequently, the ratchet 708 cannot drive the second transmission wheel 712 to rotate via the pawl 709, the fixing rod 710, and the sleeve 711. Conversely, when the dual-axis motor 701 rotates in the reverse direction (driving the first restraining chain assembly 32 to tighten the split conductor assembly), the ratchet 708 cannot drive the second transmission wheel 712 to rotate. 2. When the split conductor group is relaxed, the drive shaft 707 drives the ratchet 708 to rotate in the opposite direction. The ratchet 708 is blocked by the pawl 709, which causes the ratchet 708, in conjunction with the pawl 709, the fixed rod 710, the sleeve 711, the second transmission wheel 712, and the second transmission belt 713, to drive the transmission shaft 714 to rotate. This, in turn, causes the transmission shaft 714 to drive the drive arm 803 to rotate. Through the two auxiliary shafts 802, and the line connecting the center of the transmission shaft 714 and the two auxiliary shafts 802 forming an equilateral triangle, when the transmission shaft 714 drives the drive arm 803 to rotate, the drive arm 803 will drive the movable plate 804 to move, forming a spring-driven walking mechanism. This allows the movable plate 804 to cooperate with the connecting plate 805 and the movable... The groove 806 and the movable rod 807 drive the traveling plate 808 to make regular arc movements. When the traveling plate 808 makes arc movements, it will collide with the branch wire 1 and generate vibrations. The vibrations are mutual, and the traveling plate 808 will transmit the vibrations to the first restraint chain assembly 32 and the second restraint chain assembly 35 through the traveling frame 801, the motor bracket 715, the mounting plate 6, and the fixing seat 4. This causes the traveling plate 808, together with the first restraint chain assembly 32 and the second restraint chain assembly 35, to simultaneously vibrate the branch wire 1, thereby shaking off the ice on the surface of the branch wire 1, thus further achieving the de-icing effect. Furthermore, when the traveling plate 808 makes arc movements, because the bottom of the traveling plate 808 has multiple protrusions... Furthermore, the rough bottom of the walking plate 808 causes significant friction between it and the branch conductor 1. This allows the walking plate 808 to move in an arc shape. The walking frame 801, in conjunction with the motor bracket 715, mounting plate 6, and fixed base 4, moves the de-icing assembly 3 across the surface of the branch conductor assembly, thus achieving automatic de-icing. By incorporating the first crossbar 809, telescopic rod 810, second damping spring 811, and second crossbar 812, when the branch conductor 1 is taut and difficult to bend, the walking plate 808 can still move in an arc shape. In this case, the walking plate 808 presses against the telescopic rod 810 and the second damping spring 811 via the movable rod 807 and movable groove 806, thereby changing the range of motion of the walking plate 808.This allows the walking plate 808 to continuously and normally perform arc-shaped movements, driving the de-icing assembly 3 forward.
