[0001] The utility model relates to the technical field of ground down conductor welding, in particular to a ground down conductor quick welding device. Background Art

[0002] The grounding system of transmission and distribution line towers is exposed to the outdoor environment for a long time. Due to factors such as rust, lightning melting or external force damage, the grounding down conductor is prone to breakage in the contact area between the base of the tower and the soil, resulting in a significant increase in grounding resistance. Such faults interrupt the lightning current discharge channel. When the line is struck by lightning, the high-amplitude lightning current cannot be effectively conducted into the earth, causing insulator flashover and line tripping accidents. Tripping incidents caused by such faults are particularly frequent in mountainous areas and areas with frequent lightning strikes, resulting in power supply interruptions and power losses.

[0003] Traditional repair methods rely on on-site welding operations, and heavy welding equipment needs to be manually transported to the pole tower location in complex terrain. The operation process is time-consuming and labor-intensive. On steep slopes and muddy roads, equipment transportation is difficult and the safety risks are high, resulting in time-consuming and labor-intensive welding work of the grounding down conductor, and there are also great safety hazards.

[0032] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below with reference to specific implementation methods and the accompanying drawings.

[0033] The terms used in this utility model are those commonly used in the art in view of the functions of the utility model, but these terms may vary according to the intentions of ordinary technicians in the art, precedents, or new technologies in the art. In addition, specific terms may be selected by the applicant, and in this case, their detailed meanings will be described in the detailed description of the utility model. Therefore, the terms used in the specification should not be understood as simple names, but are based on the meaning of the terms and the overall description of the utility model.

[0034] Reference Figures 1 to 5 The present embodiment provides a ground down conductor rapid welding device, including a charge tank 1. The charge tank 1 is made of ceramic material and can effectively resist the influence of high temperature, ensuring that the welding powder 7 is always located inside the charge tank 1 during combustion; a cylindrical groove 11 is provided in the center of the charge tank 1, circular hole grooves 12 are provided on both sides of the cylindrical groove 11, and a U-shaped groove 13 is provided between the cylindrical groove 11 and the circular hole groove 12.

[0035] Furthermore, the cylindrical groove 11 is filled with welding powder 7; the circular hole groove 12 is interspersed with a wire 8; the welding powder 7 is composed of magnesium powder, thermite and other inevitable impurities; the magnesium powder has a low ignition point and can be directly ignited by a portable fire source such as a lighter or a match; and the magnesium powder can release a high temperature of up to 2500 degrees after burning, and the high temperature of 2500 degrees can ignite the thermite, causing the thermite to react. After the thermite reacts, it melts inside the cylindrical groove 11, and the melted thermite contacts the wire 8; after the temperature drops, the thermite reactant is converted into solid metal aluminum and connected to the wire; and aluminum has good conductivity and low resistance when current passes through, further ensuring the stability of the current passing through the welding position.

[0036] Specifically, in the present invention, the amount of welding powder 7 required for each welding is controlled at about 200 grams. The welding powder 7 is poured into the cylindrical groove 11 and does not overflow, which can meet the amount of welding powder required for a single grounding down conductor welding. Thermite welding powder is an existing mature product, and specific reference can be made to thermite welding powder already sold on the market.

[0037] Furthermore, a partition 2 is provided inside the U-shaped groove 13 to isolate the cylindrical groove 11 from the inner space of the circular hole groove 12 ; when the solder powder 7 is ignited, it releases heat, and the partition 2 melts when heated, causing the solder powder 7 to come into direct contact with the wire 8 .

[0038] It should be noted that the cross-section of the U-shaped groove 13 is an arc-shaped structure, and the partition 2 has a certain bending and deformation ability; by bending the partition 2 and inserting it into the U-shaped groove 13, the partition 2 releases elastic potential energy, so that the side wall of the partition 2 contacts the inner wall of the U-shaped groove 13, thereby fixing the partition 2 inside the U-shaped groove 13.

[0039] Specifically, the space between the cylindrical groove 11 and the circular hole groove 12 is separated by the partition 2; when the solder powder 7 burns and releases heat, the partition 2 will melt before the thermite reacts, so that part of the solid thermite enters the circular hole groove 12 and directly contacts the wire 8. When the magnesium powder releases enough heat, it will promote the reaction of the thermite. Since part of the thermite is already located in the circular hole groove 12, it effectively reduces the blistering generated during the flow of liquid aluminum from the cylindrical groove 11 to the circular hole groove 12.

[0040] It should be noted that the welding powder includes thermite and magnesium powder, which are mixed in a certain proportion; the welding powder is located inside the cylindrical groove 11, and a fuse can be placed inside the cylindrical groove 11, and the fuse can be ignited to ignite the magnesium powder, thereby achieving melting of the welding powder.

[0041] Specifically, the conductor 8 is part of the grounding down conductor. When the grounding down conductor is disconnected from the middle position, it will be divided into two conductors 8. During the welding process of the grounding down conductor, it is only necessary to weld and fix the two conductors 8 to ensure that the grounding down conductor is grounded normally.

[0042] During use, the staff inserts the two wires 8 into the circular hole grooves 12 on both sides of the charge tank 1 respectively, and then pre-fixes the wires 8 in the circular hole grooves 12 with the bolts 3; then places the lead wire in the cylindrical groove 11, and then fills the cylindrical groove 11 with welding powder 7, with the end of the lead wire extending to the outside of the opening position of the cylindrical groove 11, so that the staff can ignite the lead wire; then the staff ignites the lead wire, and the lead wire ignites the magnesium powder mixed with the thermite in the cylindrical groove 11; the magnesium powder burns and releases high temperature to melt the partition 2. After the partition 2 melts, the thermite enters the circular hole groove 12, and the magnesium powder releases high temperature to ignite the thermite in the circular hole groove 12, so that the cylindrical groove 11 and the circular hole groove 12 are all heat-reactive thermite; when the aluminum solidifies, the two sets of wires 8 are connected.

[0043] Reference Figures 1 to 4 As an optional embodiment, the cylindrical groove 11 and the circular hole groove 12 are connected through a U-shaped groove 13; the partition 2 is inserted into the inner side of the U-shaped groove 13.

[0044] It should be noted that the partition 2 is made of tin or tin alloy, which has a low melting point. The partition 2 can be melted after the magnesium powder is ignited, so that the partition 2 melts before the thermite reacts to ensure that part of the thermite can enter the circular hole groove 12 before reacting.

[0045] Specifically, the partition 2 is inserted into the U-shaped groove 13 by plugging. The partition 2 is deformed under pressure and the outer wall contacts the inner wall of the U-shaped groove 13. The partition 2 is fixed in the U-shaped groove 13 by the reverse elastic force of the partition 2.

[0046] Furthermore, the end surface of the partition 2 close to the top cover 4 is flush with the top of the medicine tank 1; the top of the partition 2 is flush with the top of the medicine tank 1, thereby ensuring that the partition 2 can completely separate the space between the cylindrical groove 11 and the circular hole groove 12.

[0047] Furthermore, threaded holes 14 are provided on both sides of the medicine-charging tank 1, and the threaded holes 14 pass through the side walls of the medicine-charging tank 1 and extend to the inside of the circular hole groove 12; a bolt 3 is provided inside the threaded hole 14, and the bolt 3 is threadedly engaged with the threaded hole 14; while the bolt 3 rotates, it moves along the axial direction of the threaded hole 14, and the inner wall of the circular hole groove 12 contacts the outer wall of the wire 8, thereby fixing the wire 8 inside the circular hole groove 12.

[0048] It should be noted that in order to accommodate stable connections of wires 8 of different thicknesses, a threaded hole 14 is provided on the side wall of the medicine tank 1, and a bolt 3 is provided inside the threaded hole 14, and the bolt 3 is threadedly matched with the threaded hole 14. By manually rotating the bolt 3, the staff can make the end of the bolt 3 contact the outer wall of the wire 8 and press the wire 8 into the circular hole groove 12, thereby pre-fixing the wire 8.

[0049] Reference Figures 1 to 6 In one embodiment provided by the present invention, a top cover 4 is hingedly connected to the top of the medicine tank 1; a notch 41 is opened on the side wall of the top cover 4.

[0050] It should be noted that the top cover 4 and the medicine tank 1 are hingedly connected by a hinge, and a notch 41 is provided on the side wall of the top cover 4. The lead located inside the cylindrical groove 11 can be extended through the notch 41, making it easier for the staff to ignite the welding powder 7 inside the cylindrical groove 11.

[0051] Specifically, when the welding powder 7 is ignited, the top cover 4 needs to be flipped over to seal the top opening of the cylindrical groove 11; during the combustion process, the flame will flow, and the flowing flame will turn back downward after contacting the top cover 4, thereby further ensuring that the temperature inside the cylindrical groove 11 meets the requirements for the full reaction of the thermite.

[0052] Furthermore, a bottom cover 5 is provided at the bottom of the medicine tank 1 ; the bottom cover 5 is a truncated cone-shaped structure, and the bottom cover 5 blocks the bottom opening of the medicine tank 1 .

[0053] It should be noted that the bottom cover 5 is arranged in the vertical direction, and the bottom cover 5 is installed at the bottom of the cylindrical groove 11 to seal the bottom of the cylindrical groove 11; and the end with a smaller diameter of the bottom cover 5 is close to the top of the medicine tank 1, and the end with a larger diameter is away from the top of the medicine tank 1.

[0054] Specifically, the bottom cover 5 is designed in a conical shape so that the liquid aluminum below the cylindrical groove 11 can enter the circular hole groove 12 along the side wall of the bottom cover 5 to reduce the accumulation of thermite at the bottom of the cylindrical groove 11.

[0055] Furthermore, a tensioning member 6 is provided inside the circular hole groove 12 ; a deformation groove 61 is provided on the side wall of the tensioning member 6 ; and the inner wall of the tensioning member 6 can contact the outer wall of the wire 8 .

[0056] It should be noted that the tensioning member 6 is installed at the bottom of the medicine tank 1, and the tensioning member 6 has a certain deformation ability; when the wire 8 is inserted into the circular hole groove 12, the outer wall of the wire 8 will contact the inner wall of the tensioning member 6, and the tensioning member 6 will be squeezed by the wire 8 and opened, and the wire 8 will be fixedly clamped inside the tensioning member 6.

[0057] Specifically, the tensioning member 6 can further reduce the gap between the wire 8 and the circular hole groove 12 at the bottom of the medicine tank 1, further restricting the solder powder 7 from falling from the gap between the wire 8 and the circular hole groove 12, thereby avoiding the waste of solder powder 7 to a certain extent.

[0058] Finally, it should be pointed out that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways without departing from the scope of the present invention.

[0059] It is important to note that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
