Description

Technical Field

[0001] The present invention relates to the technical field of quick connection devices for ground wires, in particular to a quick connection device for installing a 750 kV ground wire using an unmanned aerial vehicle. Background Art

[0002] Grounding wires are a core safety measure during high-voltage equipment maintenance. They quickly discharge residual electrical charge from equipment and lines during power outages to prevent electric shock. They connect the equipment's metal casing to the ground, creating a zero-potential reference and preventing insulation damage from causing electrical damage. In the event of a sudden leakage or short circuit, the grounding wire acts as a low-impedance path to quickly conduct the fault current, reducing the abnormal potential and minimizing the scope of the accident. By creating an artificial short circuit, the grounding wire maintains zero line potential, providing a strong safety barrier through charge discharge, potential clamping, and fault current limiting.

[0003] In the power system, 750 kV high-voltage electrical equipment is a key transmission link, and its safe and stable operation is crucial to the reliability of the entire power grid. However, facing such a high voltage level, traditional grounding wire installation methods face many challenges: 1. Operational complexity: When installing the grounding wire on the mother pipe, multiple windings are usually required to ensure the connection is secure. This process is not only time-consuming and labor-intensive, but also requires operators to have high skills and experience. 2. Operational difficulty: Due to the high voltage level of 750 kV, its electrical equipment is usually large and complex. In this case, the installation and removal of the grounding wire are correspondingly more difficult, requiring operators to operate in complex environments such as high altitudes. 3. High safety risks: When performing grounding operations in a high-voltage environment, operators face safety risks such as electric shock, falling from height, and accidentally touching equipment, which may even cause serious safety accidents.

[0004] Therefore, with the continuous development of power systems and the continuous improvement of voltage levels, traditional grounding wire installation methods can no longer meet the needs of modern power systems. It is urgent to develop and promote new technologies and equipment for grounding wire installation that are safer, more efficient and more convenient to ensure the safe and stable operation of power systems.

[0022] The present invention is not limited to the following embodiments, and specific implementation methods can be determined based on the technical solutions of the present invention and actual conditions.

[0023] In the present invention, for the convenience of description, the relative position relationship of each component is described based on the Figure 1 For example, the positional relationships of front, back, up, down, left, and right are determined according to the layout directions of the drawings in the specification.

[0024] The present invention will be further described below in conjunction with the embodiments and accompanying drawings: Example 1: As shown in the attached Figure 1-6 As shown, the quick connection device for installing a 750 kV grounding wire using a drone includes a cylindrical tube mother 1, a clamp 2 is provided on the cylindrical tube mother 1, a docking part 3 is installed on the clamp 2, the docking part 3 is plugged with the plug-in part 4 through a docking clamping mechanism 6, a terminal 5 is provided at the bottom of the plug-in part 4, a connecting mechanism 7 for connecting a drone is provided on the plug-in part 4, and a quick disassembly mechanism 12 for quickly disassembling from the plug-in part 4 is provided on the docking part 3.

[0025] During use, the clamp 2 is fixed to the cylindrical tube mother 1 in advance, and the grounding wire is connected to the terminal 5. The connecting mechanism 7 is then installed on the drone, and the plug-in part 4 is fixed to the connecting mechanism 7. During connection, the drone is operated to drive the plug-in part 4 to rise, and the plug-in part 4 is inserted into the docking part 3. Under the action of the docking clamping mechanism 6, the plug-in part 4 can be clamped into the docking part 3, and the quick connection of the terminal 5 can be completed. By docking the docking part 3 and the plug-in part 4 operated by the drone, the risks of falling from a height and injuring people with induced electric shock during manual installation can be effectively avoided, thereby avoiding safety accidents. The drone can quickly release the clamping of the docking clamping mechanism 6 by pulling the quick disassembly mechanism 12, facilitating the disassembly of the plug-in part 4, and then facilitating the disassembly of the terminal 5 and the grounding wire. It can effectively reduce the safety risks of workers working at height and at high voltage, and the plug-in structure and quick disassembly structure 12 are faster, saving time and effort.

[0026] The above-mentioned quick-connect device for installing a 750 kV grounding wire using a drone can be further optimized and / or improved according to actual needs: Example 2: As shown in the attached Figure 2-4 As shown, the docking locking mechanism 6 includes movable grooves 61 respectively arranged on the left and right sides of the plug-in part 4, and a clamping block 62 is provided on the outside of each movable groove 61. A telescopic spring 63 is installed between the clamping block 62 and the bottom of the movable groove 61. The clamping block 62 can be pushed into the movable groove 61. An installation groove that can accommodate the upper part of the plug-in part 4 is provided in the docking part 3, and a clamping groove 64 is provided on the docking part 3 corresponding to the position of the clamping block 62.

[0027] The plug-in process is to operate the drone to drive the plug-in part 4 to rise and insert the plug-in part 4 into the docking part 3. At this time, the clamping block 62 is squeezed by the inner wall of the installation groove and enters the movable groove 61, and the telescopic spring 63 is also compressed. When the hole positions of the clamping block 62 and the clamping groove 64 coincide, the clamping block 62 is driven to engage into the clamping groove 64 under the action of the telescopic spring 63, thereby completing the operation of inserting the plug-in part 4 into the docking part 3, thereby connecting the terminal 5 and the grounding wire to the cylindrical tube mother 1, and completing the grounding operation.

[0028] Example 3: As shown in the attached Figure 2-4 As shown, the block 62 is triangular in shape, with the inclined surface located outside the movable groove 61. A micro-guide telescopic rod 65 located within a telescopic spring 63 is installed between the block 62 and the bottom of the movable groove 61. The micro-guide telescopic rod 65 can guide the movement of the block 62, so that the block 62 can only move back and forth within the movable groove 61.

[0029] Example 4: As shown in the attached Figure 2As shown, the connecting mechanism 7 includes a lower fixed plate 75 and an L-shaped inserting bracket 72. Two support blocks 74 are spaced apart on the left and right sides of the lower fixed plate 75. A double-headed screw 73 is installed between the two support blocks 74. The two parts of the double-headed screw 73 are screwed to the opposite L-shaped inserting brackets 72 respectively. Slots 71 are provided on the front and rear sides of the plug-in portion 4. The other ends of the two L-shaped inserting brackets 72 are respectively located in the slots 71 at corresponding positions. The rotation of the double-headed screw 73 will drive the two L-shaped inserting brackets 72 to move closer to each other and engage the ends in the slots 71, thereby fixing the connecting mechanism 7 to the plug-in portion 4, so that the plug-in portion 4 can be plugged into the docking portion 3 through the movement of the connecting mechanism 7. The reverse rotation of the double-headed screw 73 will drive the two L-shaped inserting brackets 72 to move away from each other, thereby disengaging the connecting mechanism 7 from the plug-in portion 4.

[0030] Example 5: As shown in the attached Figure 2 As shown, one end of the double-ended screw 73 is connected to a drive motor 76, and a battery 77 is provided on the lower fixing plate 75. A fixing bolt 78 for connecting to the drone is installed on the lower fixing plate 75. The fixing bolt 78 fixes the lower fixing plate 75 to the drone, and the rotation of the drive motor 76 drives the double-ended screw 73 to rotate.

[0031] Example 6: As shown in the attached Figure 2 As shown, a guide rod 710 is fixedly installed between the two support blocks 74, and one end of each of the two L-shaped inserting frames 72 is installed with a guide sleeve 79 sleeved on the guide rod 710. The guide sleeve 79 slides on the guide rod 710 and can guide the movement of the L-shaped inserting frame 72.

[0032] Example 7: As shown in the attached Figure 5-6As shown in the figure, there are two sets of symmetrically arranged quick disassembly mechanisms 12 on the docking part 3. The quick disassembly mechanism 12 includes a socket row 121 with its inner end inserted into the card slot 64, a vertical rod 122, and a rotating rod 123. A vertical rod 122 is fixedly installed on the socket row 121. There is a through waist-shaped slot 1210 on the vertical rod 122. An active round pin 1211 is slidably clamped in the waist-shaped slot 1210. One end of the rotating rod 123 is rotatably installed on the active round pin 1211. A T-shaped movable block 124 is slidably arranged on the docking part 3. The other ends of the rotating rods 123 of the two sets of quick disassembly mechanisms 12 are both rotatably installed on the T-shaped movable block 124. A hook 125 is fixedly installed on the lower side of the T-shaped movable block 124. The hook 125 is in a U-shaped with an opening facing backward. An extension block 126 located inside the hook 125 is fixedly installed on the docking part 3. A support spring 127 is fixedly installed between the extension block 126 and the upper part of the hook 125. The reverse drive motor 76 drives a set of L-shaped plug brackets 72 to move away from each other and fit against the corresponding support blocks 74 respectively. The L-shaped plug brackets 72 are moved by the drone and are hooked between the lower part of the hook 125 and the extension block 126. The drone moves the hook 125 downward. The downward movement of the hook 125 compresses the support spring 127 and带动 the T-shaped movable block 124 to move downward. The T-shaped movable block 124 pulls the lower part of the rotating rod 123 to rotate and move downward. The upper part of the rotating rod 123 moves upward and inward in the waist-shaped slot 1210, pushing the vertical rod 122 to move inward, so that the socket row 121 moves into the card slot 64, pushing the locking block 62 into the movable slot 61. At this time, under the action of the gravity of the plugging part 4, the terminal block 5 and the grounding wire, the plugging part 4 will be带动 to fall off from the docking part 3, and the removal of the plugging part 4, the terminal block 5 and the grounding wire can be completed.

[0033] Example 8: As shown in the appendix Figure 6 As shown in the figure, a slide bar 129 is fixedly installed on the extension block 126, and a slide sleeve 128 is fixedly installed on the hook 125. The slide sleeve 128 is slidably sleeved on the slide bar 129. The sliding of the slide sleeve 128 on the slide bar 129 can guide the movement of the T-shaped movable block 124, making the T-shaped movable block 124 only movable up and down.

[0034] Example 9: As shown in the appendix Figure 5 As shown in the figure, a limit block 1212 is provided on the socket row 121. The limit block 1212 limits the position of the socket row 121 inserted into the card slot 64, making the farthest distance that the socket row 121 moves inward at the inner end of the card slot 64, avoiding the socket row 121 penetrating too deep inward and抵住 the plugging part 4 so that it cannot fall off, ensuring smooth disassembly.

[0035] Example 10: As shown in the appendix Figure 4-5As shown, a first magnetic strip 8 is fixedly mounted on both sides of the plug-in portion 4, a second magnetic strip 9 is fixedly mounted within the docking portion 3, and the first and second magnetic strips 8 and 9 are in close contact with each other. A spring piece 10 is fixedly mounted at the bottom of the mounting groove within the docking portion 3, and a contact portion 11 is fixedly mounted on the top of the plug-in portion 4, and the spring piece 10 and contact portion 11 are in close contact with each other. The contact portion 11 and the spring piece 10 enable an electrically conductive connection between the docking portion 3 and the plug-in portion 4. The mutual attraction between the second magnetic strip 9 and the first magnetic strip 8 enhances the stability of the docking between the docking portion 3 and the plug-in portion 4.

[0036] The above technical features respectively constitute the embodiments of the present invention, which have strong adaptability and implementation effect. Non-essential technical features can be added or removed according to actual needs to meet the requirements of different situations.
