Technical Field
[0001] This utility model relates to the field of overhead power line de-icing technology, specifically an optimized automatic wiring device for ground wire de-icing. Background Technology
[0002] Automatic ground wire de-icing connection devices are one of the key technologies for power systems to cope with winter rain, snow, and ice disasters. In high-voltage transmission lines, in addition to the phase wires (live wires) that transmit electrical energy, there are one or two overhead ground wires at the top. Their main functions are lightning protection and communication. However, in severe cold rain and snow, the ground wires can also become covered with ice, just like the phase wires. Excessive ice accumulation can collapse towers and break lines, causing major accidents. Currently, wire de-icing technology is quite mature, usually employing the "short-circuit current method," which involves passing a large current through the line and using its resistance to heat up and melt the ice. However, ground wires are usually directly grounded and cannot be directly connected to current. Automatic ground wire de-icing connection devices were developed to solve this problem. It is an automated device installed on the grounding wire support of the tower. Its core function is to automatically disconnect both ends of the grounding wire from the grounding state and connect it to the de-icing power supply when de-icing is required, forming a current loop; after de-icing is completed, it automatically restores the grounding wire to its normal grounding state. Essentially, it is a switching switch. Currently, the common method is to use a drive device to drive the conductor to swing, so that it connects to the power source or grounding structure to achieve switching. For example, Chinese invention patent CN107508237B discloses an automatic grounding wire de-icing connection device with an upper-closing type, which includes an upper-closing power source, a transmission mechanism, an opening and closing conductor, a falling protective cover, and an electrical control system. The transmission mechanism is installed on a platform on the side of the tower. One end of the opening and closing conductor is connected to the output flange of the transmission mechanism, and the other end is equipped with an adjustable contact. However, the current automatic grounding wire de-icing connection device has the following defects: Currently, the automatic grounding de-icing wiring device uses a drive unit to switch the conductor. After switching, the conductor needs to be kept in a fixed position. This requires the motor in the drive unit to be kept powered on to fix the conductor's position, which consumes a lot of electrical energy. In low-temperature environments, this electrical energy is quite precious. There is also a risk of the motor losing power at low temperatures, which could cause the conductor to fall off and leave the power source.
[0003] Therefore, we propose an optimized automatic ground wire de-icing connection device to solve the above problems. Utility Model Content

[0016] Please see Figure 1-6 This is the second embodiment of the present invention. Based on the previous embodiment, a horizontally formed horizontal columnar groove 413 is opened on the side wall of the horizontal groove 47. A horizontally formed through groove 414 is opened at the end of the horizontal columnar groove 413. The through groove 414 connects to the interior of the second housing 41.

[0018] The second housing 41 is internally fixed with a second torque motor 421 and a second reducer 422.

The other end of the first pull rod 424 is rotatably connected to the end of a crossbar 415, and the other end of the second pull rod 425 is rotatably connected to the top of a vertical rod 419. The second torque motor 421 drives the turntable 423 to rotate, which in turn generates a pulling force on the crossbar 415 and the vertical rod 419 through the first pull rod 424 and the second pull rod 425, causing the first arc block 48 and the second arc block 411 to retract. This unlocks the arc slider 45, and the drive structure 3 can then drive the conductor structure 2 to perform a switching action.
[0019] A drive shaft column 33 is horizontally rotatably connected at the pivot 32. The drive shaft column 33 is fixedly sleeved on the end of the power rotating plate 21. A power shaft 34 is horizontally rotatably connected inside the first housing 31 at the position corresponding to the drive shaft column 33.

The shaft end of the first torque motor 35 is fixedly connected to the input shaft of the first reducer 36. The output shaft of the first reducer 36 is fixedly connected to the active synchronous pulley 37. A driven synchronous pulley 38 is fixedly sleeved on the power shaft 34. A synchronous belt 39 is sleeved on the active synchronous pulley 37 and the driven synchronous pulley 38. The first torque motor 35 is used to drive the conductor structure 2 to swing to achieve the switching action.
[0020] The power plate 21 is fixed to a conductive arm 22 at one end away from the drive structure 3. An outer tube 23 is fixed to the side wall of the end of the conductive arm 22.

A wiring 27 is fixed to the end of the power plate 21.
[0021] In this invention, the power take-up device 1 is installed on the power tower via an insulator jumper string 11, and the drive structure 3 is also installed on the power tower. Under normal conditions, the end of the ground wire is electrically connected to the connection 27, and the conductor structure 2 should be vertically connected to the power connection facility at the bottom of the power tower. When ice melting is required, the second torque motor 421 in the auxiliary locking structure 4 drives the turntable 423 to rotate. This generates tension on the crossbar 415 and the vertical bar 419 through the first pull rod 424 and the second pull rod 425, causing the first arc block 48 and the second arc block 411 to retract. This unlocks the arc slider 45, and the drive structure 3 can then drive the conductor structure 2 to rotate, causing it to swing and connect with the power take-up device 1. After completion, the power is cut off at the second torque motor 421, and the first arc block 48 and the second arc block 411 are driven to rotate under the action of the first spring 416 and the second spring 420. The surface block 48 and the second arc surface block 411 spring back to their original positions, so that the first locking pin 49 inserts into the locking port 46 in the arc slider 45 to lock the position of the conductor structure 2. At this time, the drive structure 3 can be de-energized to achieve switching. Power is supplied from the power source 1, causing the ground wire to heat up and melt the ice. The auxiliary locking structure 4 additionally provided in this utility model is used to help fix the conductor structure 2. When the conductor structure 2 is connected to the power source 1 for ice melting, the first locking pin 49 of the first arc surface block 48 is inserted into the locking port 46 in the arc slider 45 to achieve fixation. In this way, the drive structure 3 only needs to drive the conductor structure 2 to perform the switching action. After completion, the auxiliary locking structure 4 helps to lock the position of the conductor structure 2. The drive structure 3 does not need to continue to be energized, saving energy and avoiding the risk of the conductor structure 2 falling off due to power failure.
