[0023] A method for using a grounding device for an oil-immersed transformer comprises the following steps:

[0024] S1. When the transformer body vibrates during use, the vibrating transformer will swing synchronously with the bottom hinged adjusting rod. Since the upper part of the adjusting rod forms a lever structure with the fulcrum ring on the supporting ring through the conical ring sleeve, the center position of the fulcrum ring is used as the fulcrum to make the lower part of the adjusting rod move in the opposite direction of the upper part of the adjusting rod. Then the ball head at the lower part of the adjusting rod presses against the side wall of the adjacent cone block, so that the cone block is pressed to slide downward inside the gas cylinder. The downward moving cone block presses the gas piston plate downward. At this time, the one-way valve on the side wall of the gas cylinder is closed, and the one-way valve at the bottom of the gas cylinder is opened to transport gas to the inside of the gas storage cylinder. When the adjusting rod is reset and swung, the reset spring brings the gas piston plate to rise and reset quickly, so that the one-way valve at the side wall of the gas cylinder is opened, and the one-way valve at the bottom of the gas cylinder is closed. With the reciprocating swing of the adjusting rod, the gas cylinder continues to slowly transport gas to the inside of the gas storage cylinder.

[0025] S2. As the gas enters the gas cylinder, the gas piston plate inside the gas cylinder slowly moves down inside the gas cylinder. At this time, the gas piston plate moves down with the T-shaped pressure rod at the bottom and presses against the inclined side wall of the adjustment plate. At this time, the inclined surface of the trapezoidal movable block on the surface of the T-shaped pressure rod is pressed to move into the movable groove. When the T-shaped pressure rod brings the trapezoidal movable block over the position of the adjustment plate, the downward moving gas piston plate brings the cone rod to press against the surface of the limit ring. At this time, the cone rod brings the cone ring up and is adsorbed on the double When the cone rod moves to the inner bottom surface of the cone groove, the gas storage piston plate no longer seals the gas inside the gas storage cylinder, and the restoring spring brings the gas storage piston plate up quickly, and then the T-shaped pressure rod moves up and presses against the end position of the adjustment plate through the trapezoidal movable block, so that the end of the trapezoidal adjustment plate close to the T-shaped pressure rod deflects downward, and when the cone rod moves up to the limit position, the top of the cone rod is pressed and stuck into the top position of the inner wall of the two-way cone groove, and the gas storage piston plate position is sealed again, and the gas storage inside the gas storage cylinder is opened again at this time;

[0026] S3, the adjustment plate deflected downward at the same time slides with the sliding groove on the surface of the U-shaped adjustment block through the sliding pin, so that the U-shaped adjustment block moves downward at the top position of the base, and the downwardly moved U-shaped adjustment block slides with the push rod through the inclined groove, so that the push rod moves with the U-shaped tooth plate toward the corresponding water storage cylinder, and during the meshing process of the U-shaped tooth plate and the circular gear at the top of the drain pipe, the secondary drain hole on the drain pipe is aligned with the main drain hole on the protective plug, so that the salt water inside the water storage cylinder is automatically discharged;

[0027] S4. At the same time, the U-shaped toothed plate with the trapezoidal top block is pressed against the bottom of the top rod at the bottom of the water storage cylinder, so that the top rod is pressed and the sealing cone pad rises, so that the sealing cone pad on the top of the top rod seals the conical groove on the top surface of the water storage cylinder, and the brine is quantitatively transported.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] In the present invention, through the coordinated use of components such as the transformer body, the power storage regulating mechanism and the drainage mechanism, the vibration generated during the use of the transformer body will drive the power storage regulating mechanism to operate, so that the power storage regulating mechanism will cooperate with the drainage mechanism in stages to automatically inject salt water into the soil at the bottom of the base, avoiding the user from regularly injecting salt water, thereby improving the convenience of use.

[0030] In the present invention, through the coordinated use of components such as the water storage tank force regulating mechanism and the drainage mechanism, when the force regulating mechanism cooperates with the drainage mechanism to perform drainage operations, the trapezoidal top block of the side wall of the U-shaped tooth plate presses against the bottom of the top rod, so that the top rod rises with the sealing cone gasket to seal the top surface of the water storage cylinder, thereby preventing the salt water inside the water storage tank from entering the water storage cylinder during the drainage process, achieving the effect of quantitative drainage, and avoiding waste caused by excessive drainage at a single time.

It should be noted that: when the trapezoidal top block 531 on the power storage adjustment mechanism 5 moves to the bottom of the top rod 703, the top rod 703 is pressed to carry the sealing cone pad 704 on the top to seal the conical groove 702 on the top surface of the water storage cylinder 701; the inner wall of the water storage cylinder 701 is provided with a sealing ring that matches the top rod 703, and when the top rod 703 moves up and down inside the water storage cylinder 701, the sealing effect inside the water storage cylinder 701 is ensured.

[0060] The bottom of the water storage cylinder 701 is fixedly connected with a sealed bearing 705, the inner ring of the sealed bearing 705 is fixedly connected with a drain pipe 706, and the upper part of the outer wall of the drain pipe 706 is fixedly sleeved with a circular gear 707 that matches the power storage adjustment mechanism 5. It should be noted that when the U-shaped toothed plate 530 on the power storage adjustment mechanism 5 moves, it will mesh with the corresponding circular gear 707, so that the circular gear 707 rotates with the drain pipe 706 inside the protective plug 708; and only one side of the inner wall of the U-shaped toothed plate 530 is provided with teeth that match the circular gear 707.

[0061] The outer ring of the drain pipe 706 is rotatably connected with a protective insert 708, which is fixedly connected to the surface of the base 1. The lower part of the protective insert 708 is symmetrically provided with a main drain hole 709, and the lower part of the drain pipe 706 is provided with a secondary drain hole 710 that matches the main drain hole 709. The main drain hole 709 and the secondary drain hole 710 are staggered. It should be noted that the U-shaped tooth plate meshing with the circular gear can only rotate the drain pipe 90 degrees to ensure that the main drain hole and the secondary drain hole coincide.

[0062] In this embodiment, Figures 1 to 11 As shown, a sealing ring is provided between the upper part of the inner wall of the protective plug 708 and the drain pipe 706, and the side wall of the protective plug 708 is electrically connected to the bottom of the transformer body 3. It should be noted that the protective plug 708 penetrates the base 1 and is inserted into the soil. The electrical connection between the protective plug 708 and the transformer body 3 is a prior art and will not be described in detail here. When the transformer body 3 leaks electricity inside or outside, the current can be introduced into the ground from the protective plug 708.

[0063] In this embodiment, Figures 1 to 11 As shown, a method for using a grounding device for an oil-immersed transformer comprises the following steps:

[0064] S1. When the transformer body 3 vibrates during use, the vibrating transformer will swing synchronously with the bottom hinged adjusting rod 4. Since the upper part of the adjusting rod 4 forms a lever structure with the fulcrum ring 504 on the support ring 502 through the conical ring sleeve 503, the lower part of the adjusting rod 4 moves in the opposite direction of the upper part of the adjusting rod 4 with the center position of the fulcrum ring 504 as the fulcrum. Then the ball head 509 at the lower part of the adjusting rod 4 presses against the side wall of the adjacent cone block 508, so that the cone block 508 is pressed inside the gas cylinder 506 and slides downward. 508 presses the gas delivery piston plate 507 downward, at which time the one-way valve 511 on the side wall of the gas delivery cylinder 506 is closed, while the one-way valve 511 at the bottom of the gas delivery cylinder 506 is opened to deliver gas to the inside of the gas storage cylinder 505. When the adjusting rod 4 is reset and swung, the reset spring 510 brings the gas delivery piston plate 507 up and back quickly, so that the one-way valve 511 on the side wall of the gas delivery cylinder 506 is opened, while the one-way valve 511 at the bottom of the gas delivery cylinder 506 is closed. As the adjusting rod 4 swings back and forth, the gas delivery cylinder 506 continues to slowly deliver gas to the inside of the gas storage cylinder 505.

[0065] S2. As the gas enters the gas storage cylinder 505, the gas storage piston plate 512 inside the gas storage cylinder 505 slowly moves downward inside the gas storage cylinder 505. At this time, the gas storage piston plate 512 moves downward with the bottom T-shaped pressure rod 518 and presses against the side wall of the inclined adjustment plate 523. At this time, the inclined surface of the trapezoidal movable block 520 on the surface of the T-shaped pressure rod 518 is pressed to move toward the inside of the movable groove 519. When the T-shaped pressure rod 518 and the trapezoidal movable block 520 pass the position of the adjustment plate 523, the downward moving gas storage piston plate 512 and the cone rod 514 press against the surface of the limit ring 516. At this time, the cone rod 514 and the cone ring 515 rise and The gas storage piston plate 512 is adsorbed on the inner bottom surface of the two-way cone groove 513, so that the gas storage piston plate 512 no longer seals the gas inside the gas storage cylinder 505, and the restoring spring 517 brings the gas storage piston plate 512 up quickly, and then the T-shaped pressure rod 518 moves up and presses against the end position of the adjustment plate 523 through the trapezoidal movable block 520, so that the end of the trapezoidal adjustment plate 523 close to the T-shaped pressure rod 518 deflects downward, and when the cone rod 514 moves up to the limit position, the top of the cone rod 514 is pressed and stuck into the top position of the inner wall of the two-way cone groove 513, and the gas storage piston plate 512 is sealed again. At this time, the inside of the gas storage cylinder 505 is opened to store gas again;

[0066] S3, the adjustment plate 523 deflected downward at the same time slides with the slide groove 526 on the surface of the U-shaped adjustment block 524 through the slide pin 525, so that the U-shaped adjustment block 524 moves downward at the top position of the base 1, and the downwardly moved U-shaped adjustment block 524 slides with the push rod 528 through the inclined groove 527, so that the push rod 528 moves with the U-shaped tooth plate 530 toward the corresponding water storage cylinder 701, and during the meshing process of the U-shaped tooth plate 530 and the circular gear 707 at the top of the drain pipe 706, the secondary drain hole 710 on the drain pipe 706 is aligned with the main drain hole 709 on the protective insert 708, so that the salt water inside the water storage cylinder 701 is automatically discharged;

[0067] S4. At the same time, the U-shaped tooth plate 530 with the trapezoidal top block 531 is pressed against the bottom of the top rod 703 at the bottom of the water storage cylinder 701, so that the top rod 703 is pressed and the sealing cone pad 704 rises, so that the sealing cone pad 704 on the top of the top rod 703 seals the conical groove 702 on the top surface of the water storage cylinder 701, and the salt water is quantitatively transported.
