[0018] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0019] Embodiment 1, as Figure 1 to Figure 2 as well as Figures 5 to 9 As shown, a method for connecting a galvanized copper stranded wire for grounding proposed by the present invention comprises: Step 1: Clean the connection between the grounding copper rod 6 and the galvanized copper stranded wire 601; Step 2: contact the grounding copper rod 6 and the galvanized copper stranded wire 601, and weld the grounding copper rod 6 and the galvanized copper stranded wire 601; Step 3: Connect the grounding copper rod 6 to the grounding grid; The above-mentioned galvanized copper stranded wire connection method for grounding also involves a galvanized copper stranded wire connection device for grounding: a galvanized copper stranded wire connection device for grounding includes a support frame 1 and a welding mold 2 installed on the support frame 1, and the welding mold includes two templates 201 slidably installed on the support frame 1, and a cover plate 202 is rotatably installed on one of the templates 201, and an ignition protection mechanism is installed on the cover plate 202, and the ignition protection mechanism transports the fire source to the inside of the two templates 201 in one direction and shields the flame inside the template 201. By transporting the fire source to the inside of the two templates 201 by the ignition protection mechanism, the flux can be ignited, and welding operations can be performed, and the flux can be prevented from spraying flames, thereby effectively preventing the problem of burns to the staff during the process of welding and igniting the flux.

[0020] Among them, the cover plate 202 is provided with an exhaust hole 203, and the welding mold 2 also includes a copper rod through hole 204 and a copper wire through hole 205 fixed on the template 201, and a flux placement groove 206. The grounding copper rod 6 is placed inside the copper rod through hole 204, and the galvanized copper stranded wire 601 is placed inside the copper wire through hole 205, and then the flux is placed inside the flux placement groove 206, and then the cover plate 202 is closed to ignite the flux. When the flux burns, it will release heat to the outside through the exhaust hole 203. After the flux is ignited, the molten metal liquid flows downward under the action of gravity and reaches the connection between the grounding copper rod 6 and the galvanized copper stranded wire 601, and finally solidifies to form a welding point 602, thereby realizing the connection between the galvanized copper stranded wire 601 and the grounding copper rod 6, and then realizing the grounding connection of the galvanized copper stranded wire 601.

[0021] Further, the ignition protection mechanism includes an ignition tube 5 fixedly mounted on the cover plate 202, the ignition tube 5 is connected to the flux placement groove 206, a first sealing plate 501 and a second sealing plate 502 are slidably mounted on the ignition tube 5, a second spring 503 is fixedly mounted on the first sealing plate 501, the other end of the second spring 503 is fixedly connected to the ignition tube 5, a lever assembly for limiting the sliding distance of the first sealing plate 501 is installed on the ignition tube 5, wherein the lever assembly includes a round rod 504 fixedly mounted on the ignition tube 5, the first sealing plate 501 is slidably connected to the round rod 504, and a limit plate 505 is fixedly mounted on the round rod 504. A pull rod 506 is fixedly mounted on the first sealing plate 501, and a transmission mechanism is installed on the ignition tube 5 to drive the second sealing plate 502 to move out of the ignition tube 5 when the first sealing plate 501 blocks the ignition tube 5. When igniting the flux, first place the fire source, such as a fireball, on the first sealing plate 501. At this time, the first sealing plate 501 and the second sealing plate 502 both block the ignition tube 5, and the fireball will be located on the first sealing plate 501. Then, the pull rod 506 is pulled to drive the first sealing plate 501 to move, so that the first sealing plate 501 is moved out from the inside of the ignition tube 5, and the fireball on the first sealing plate 501 can fall onto the second sealing plate 502. At this time, loosening the pull rod 506 will cause the first sealing plate 501 to block the ignition tube 5 again under the action of the second spring 503. At this time, the second sealing plate 502 will open and close under the action of the transmission mechanism, so that the fireball on the second sealing plate 502 falls onto the flux, and then ignites the flux, and can prevent the flame ejected when the flux is ignited from ejecting through the ignition tube 5, thereby effectively preventing burns to the staff when igniting the flux.

[0022] Furthermore, the transmission mechanism includes a base plate 507 fixedly mounted on the ignition tube 5, a rotating rod 508 is rotatably mounted on the base plate 507, a sliding rod 509 is slidably mounted on the rotating rod 508, the sliding rod 509 is rotatably connected to the first sealing plate 501, a third spring 510 is fixedly mounted on the second sealing plate 502, the other end of the third spring 510 is fixedly connected to the ignition tube 5, a groove 511 is provided on the second sealing plate 502, a stopper 512 is slidably mounted in the groove 511, a fourth spring 513 is fixedly mounted on the stopper 512, the other end of the fourth spring 513 is fixedly connected to the groove 511, an arc portion 514 is provided on one side of the stopper 512, and a vertical portion 515 is provided on the other side of the stopper 512. Under the action of the third spring 510, the second sealing plate 502 will block the ignition tube 5 when no external force is applied. When the pull rod 506 is pulled outward, the pull rod 506 will drive the rotating rod 508 to rotate through the sliding rod 509. At this time, the bottom of the rotating rod 508 is located on the left side of the stopper 512, and gradually moves to the right during the rotation process, and finally contacts the arc portion 514 and presses the stopper 512 into the groove 511. Then the rotating rod 508 will pass through the stopper 512 and move to the right side of the stopper 512, and the stopper 512 will be reset under the action of the fourth spring 513.

[0023] When the pull rod 506 is released and moves to the right, the bottom of the rotating rod 508 will be driven to rotate to the left. The rotating rod 508 moving to the left will push the block 512 to move to the left, thereby driving the second sealing plate 502 to move, so that the second sealing plate 502 moves to the outside of the ignition tube 5, and then the fireball comes into contact with the flux through the second sealing plate 502. When the rotating rod 508 rotates to the top of the block 512, the second sealing plate 502 will be reset under the action of the third spring 510. At this time, the bottom of the rotating rod 508 will move to the left side of the block 512 again, so as to facilitate the next ignition work.

[0024] Working principle: Place the grounding copper rod 6 inside the copper rod perforation 204, and place the galvanized copper stranded wire 601 inside the copper wire perforation 205, then place the flux inside the flux placement groove 206, and then close the cover 202 to ignite the flux. When the flux burns, it will release heat outward through the exhaust hole 203. After the flux is ignited, the molten metal liquid flows downward under the action of gravity and reaches the connection between the grounding copper rod 6 and the galvanized copper stranded wire 601, and finally solidifies to form a welding point 602, thereby realizing the connection between the galvanized copper stranded wire 601 and the grounding copper rod 6, and then realizing the grounding connection of the galvanized copper stranded wire 601.

[0025] When igniting the flux, first place the fire source, such as a fireball, on the first sealing plate 501. At this time, the first sealing plate 501 and the second sealing plate 502 both block the ignition tube 5, and the fireball will be located on the first sealing plate 501. Then, the pull rod 506 is pulled to drive the first sealing plate 501 to move, so that the first sealing plate 501 is moved out from the inside of the ignition tube 5, and the fireball on the first sealing plate 501 can fall onto the second sealing plate 502. At this time, loosening the pull rod 506 will cause the first sealing plate 501 to block the ignition tube 5 again under the action of the second spring 503. At this time, the second sealing plate 502 will open and close under the action of the transmission mechanism, so that the fireball on the second sealing plate 502 falls onto the flux, and then ignites the flux, and can prevent the flame ejected when the flux is ignited from ejecting through the ignition tube 5, thereby effectively preventing burns to the staff when igniting the flux.

[0026] Embodiment 2, as Figures 1 to 4 As shown, based on the first embodiment, in this embodiment, the support frame 1 is equipped with a distance adjustment mechanism for driving the two templates 201 to move closer or further away from each other. The distance adjustment mechanism includes a bidirectional screw 3 rotatably mounted on the support frame 1, a connecting block 301 is fixedly mounted on the template 201, a guide rod 302 is fixedly mounted on the support frame 1, two connecting blocks 301 are slidably connected to the guide rod 302 and are threadedly connected to both sides of the bidirectional screw 3, and a handle 303 is fixedly mounted at both ends of the bidirectional screw 3. The bidirectional screw 3 can be driven to rotate by rotating the handle 303, and the two connecting blocks 301 can be controlled to move closer or further away from each other by changing the rotation direction of the bidirectional screw 3, thereby controlling the distance between the two templates 201, so that the grounding copper rod 6 and the galvanized copper strand 601 after welding can be easily taken out.

[0027] Furthermore, a lifting component is installed in the welding mold 2, and when the two templates 201 are closed, the lifting component drives the grounding copper rod 6 to move toward the direction close to the galvanized copper stranded wire 601 and blocks the copper rod perforation 204. It is convenient to move the grounding copper rod 6 toward the direction close to the galvanized copper stranded wire 601, thereby reducing the distance between the grounding copper rod 6 and the galvanized copper stranded wire 601, increasing the area of ​​the grounding copper rod 6 wrapped by the welding point 602, thereby improving the stability after welding and preventing the leakage of the molten solder.

[0028] Among them, the lifting component includes a placement groove 4 arranged in the template 201, a blocking block 401 is slidably installed in the placement groove 4, a connecting rod 402 is fixedly installed on the blocking block 401, the connecting rod 402 passes through one side of the template 201 and extends to the outside of the template 201, a driving rod 403 is rotatably installed on the support frame 1, a first bevel gear 404 is fixedly installed on the bidirectional screw rod 3, a second bevel gear 405 is fixedly installed on the driving rod 403, the first bevel gear 404 and the second bevel gear 405 are meshed with each other, a lifting plate 406 is slidably installed on the support frame 1, the lifting plate 406 is threadedly connected to the driving rod 403, a connecting seat 407 is fixedly installed on the lifting plate 406, a support plate 408 is slidably installed in the connecting seat 407, a first spring 409 is fixedly installed on the support plate 408, the other end of the first spring 409 is fixedly connected to the connecting seat 407, and a transmission component for driving the connecting rod 402 to move is installed on the connecting seat 407. The grounding copper rod 6 is placed on the connection seat 407 , and the grounding copper rod 6 is supported by the support plate 408 .

[0029] When the two-way screw rod 3 is rotated to drive the two templates 201 to approach each other, the driving rod 403 will be driven to rotate through the transmission of the first bevel gear 404 and the second bevel gear 405, and the rotating driving rod 403 will drive the lifting plate 406 to rise, and the rising lifting plate 406 will synchronously drive the connecting seat 407 and the grounding copper rod 6 to rise. When the grounding copper rod 6 contacts the galvanized copper stranded wire 601, the lifting plate 406 that continues to rise will compress the first spring, thereby ensuring that the grounding copper rod 6 and the galvanized copper stranded wire 601 are in contact, so that the grounding copper rod 6 and the galvanized copper stranded wire 601 maintain a small gap, which can increase the contact surface between the solder joint and the grounding copper rod 6 and the galvanized copper stranded wire 601, thereby improving the stability of welding.

[0030] Furthermore, the transmission assembly includes a bracket 410 fixedly mounted on the connection seat 407, a driving block 411 fixedly mounted on the bracket 410, a slider 413 fixedly mounted on the connection rod 402, a triangular block 412 slidably mounted on the slider 413, the driving block 411 is slidably connected to the triangular block 412, and the upper and lower sides of the triangular block 412 are respectively provided with a first limiting protrusion 414 and a second limiting protrusion 415. When the grounding copper rod 6 contacts the galvanized copper stranded wire 601, the continuously rising connection seat 407 will drive the bracket 410 to rise, and the rising bracket 410 will drive the driving block 411 to rise, and under the action of the driving block 411, the two triangular blocks 412 can be driven to shrink, so that the two blocking blocks 401 can be brought close to each other to block the copper rod perforation 204.

[0031] It is worth noting that during the rising process of the driving block 411, the triangular block 412 will not be driven to shrink immediately. It will first drive the triangular block 412 to rise. When the second limiting protrusion contacts the slider 413, the driving block 411 that continues to rise will drive the two triangular blocks 412 to shrink, thereby ensuring that the two blocking blocks 401 are close to each other after the grounding copper rod 6 contacts the galvanized copper stranded wire 601, so that the blocking block 401 clamps the grounding copper rod 6, thereby ensuring that the grounding copper rod 6 will not encounter resistance when rising.

[0032] The working principle of this embodiment is that the bidirectional screw rod 3 can be driven to rotate by rotating the handle 303. By changing the rotation direction of the bidirectional screw rod 3, the two connecting blocks 301 can be controlled to move closer or farther away from each other, thereby controlling the distance between the two templates 201, so that the grounding copper rod 6 and the galvanized copper stranded wire 601 after welding can be easily removed. When the two-way screw rod 3 is rotated to drive the two templates 201 to approach each other, the driving rod 403 will be driven to rotate through the transmission of the first bevel gear 404 and the second bevel gear 405, and the rotating driving rod 403 will drive the lifting plate 406 to rise, and the rising lifting plate 406 will synchronously drive the connecting seat 407 and the grounding copper rod 6 to rise. When the grounding copper rod 6 contacts the galvanized copper stranded wire 601, the lifting plate 406 that continues to rise will compress the first spring, thereby ensuring that the grounding copper rod 6 and the galvanized copper stranded wire 601 are in contact, so that the grounding copper rod 6 and the galvanized copper stranded wire 601 maintain a small gap, which can increase the contact surface between the solder joint and the grounding copper rod 6 and the galvanized copper stranded wire 601, thereby improving the stability of welding. When the grounding copper rod 6 contacts the galvanized copper stranded wire 601, the connecting seat 407 that continues to rise will drive the bracket 410 to rise, and the rising bracket 410 will drive the driving block 411 to rise. Under the action of the driving block 411, the two triangular blocks 412 can be driven to shrink, so that the two blocking blocks 401 can be brought close to each other to block the copper rod perforation 204.

[0033] The above specific embodiments are only several optional embodiments of the present invention.
