The end of the air inlet duct 33 is connected to the upper end of the impregnation frame 12, and the end of the air outlet duct 34 is connected to the top of the paint touch-up tank 21. The quantitative mechanism 4 includes a first guide rod 41, which is fixedly inserted at the inner upper end of the impregnation frame 12, and the bottom end of the first guide rod 41 is fixedly sleeved with a first ring 42, and the two first guide rods 41 are slidably sleeved with a first floating plate 43, and the first floating plate 43 is slidably clamped in the inner cavity of the impregnation frame 12, and the top of the first floating plate 43 is fixedly installed with a symmetrically arranged return spring 44, and the return spring 44 is movably sleeved on the first guide rod 41, and the end of the return spring 44 is fixedly connected with a second ring 45,The second collar 45 is fixedly sleeved on the first guide rod 41, an L-shaped connecting rod 46 is fixedly inserted in the middle of one side of the first floating plate 43, and a sealing slide plate 47 is fixedly sleeved at the end of the L-shaped connecting rod 46, the sealing slide plate 47 is slidably fitted with the inner wall of the impregnation frame 12, and the sealing slide plate 47 is used in conjunction with the paint repair conduit 22.
[0029] By adopting the above technical solution, when in use, the multi-stage electric push rod 14 is started and the blocking pipe cover 24 is removed, and then the multi-stage electric push rod 14 will drive the sealing top cover 15 to move upward, thereby driving the impregnation material frame 16 to move upward, until the impregnation material frame 16 moves to the highest point, the multi-stage electric push rod 14 is closed and a proper amount of insulating paint is introduced into the impregnation box body 11 and the paint touch-up tank body 21, and then the blocking pipe cover 24 is reset and a transformer to be impregnated with a proper amount of insulating paint is inserted into the impregnation material frame 16, and then the multi-stage electric push rod 14 is started again, so that the sealing top cover 15 can be driven to move downward, and then the impregnation material frame 16 can be driven to move downward, and further The step can drive the corresponding transformer to be impregnated with insulating paint to move downward until the sealing gasket 17 contacts the impregnation box 11 and is squeezed and deformed, and the multi-stage electric push rod 14 is closed. At this time, the transformer to be impregnated with insulating paint will be immersed in the insulating paint in the impregnation box 11, and the lead-out wire of the transformer to be impregnated with insulating paint will be outside the insulating paint. Then the vacuum pump body 32 is started, so that the air at the upper end of the inner cavity of the impregnation box 11 and the impregnation frame 12 can be sucked into the outlet duct 34 through the inlet duct 33 and introduced into the upper end of the inner cavity of the paint repair tank 21 by the outlet duct 34, so that the space at the upper end of the paint repair tank 21 can be pressurized. The air pressure balance pipe 25 can balance the air pressure inside it, and when the inner cavities of the impregnation box 11 and the impregnation frame 12 are evacuated into a vacuum state, the vacuum pump body 32 is closed and the impregnation operation of the transformer to be impregnated with insulating paint is continued, and after the corresponding transformer insulating paint impregnation operation is completed, the multi-stage electric push rod 14 is started, so that the impregnation material frame 16 and the transformer impregnated with insulating paint can be driven to move upward. At this time, the insulating paint liquid level in the impregnation box 11 will drop, and then the reset spring 44 will push the first floating plate 43 to move downward, so that the sealing slide plate 47 can be driven to move downward through the L-shaped connecting rod 46, and when the sealing slide plate 47 is misaligned with the paint repair conduit 22 The paint touch-up duct 22 will no longer be blocked. At this time, the insulating paint stored in the paint touch-up tank 21 will be easily introduced into the paint touch-up duct 22 under pressure and then introduced into the impregnation box 11 and the impregnation frame 12 by the paint touch-up duct 22. As the insulating paint liquid level in the impregnation box 11 and the impregnation frame 12 rises, the first floating plate 43 will be pushed up again, thereby driving the L-shaped connecting rod 46 and the sealing slide 47 to move up again and squeeze the return spring 44 again, until the sealing slide 47 blocks the paint touch-up duct 22 again, the insulating paint replenishing operation will be stopped, and then the above steps will be repeated to carry out the subsequent impregnation operation of the transformer to be impregnated with insulating paint.
[0030] The expansion mechanism 5 includes an L-shaped rotating rod 51 and a first rotating rod 52, both of which are rotatably inserted into the impregnation frame 12, and a first wheel disc 53 is fixedly sleeved on the L-shaped rotating rod 51, and a material receiving frame 54 is fixedly connected to the end of the L-shaped rotating rod 51, and the material receiving frame 54 is used in conjunction with the overflow conduit 112, and a sealing rotating plate 55 is fixedly sleeved on one end of the first rotating rod 52, and the sealing rotating plate 55 is slidably fitted with the inner wall of the impregnation frame 12, and the sealing rotating plate 55 is used in conjunction with the paint touch-up conduit 22, and a second wheel disc 56 is fixedly sleeved on the first rotating rod 52, and a transmission belt 57 is transmission sleeved between the second wheel disc 56 and the outer side of the first wheel disc 53, and a transmission belt 57 is fixedly sleeved on the end of the first rotating rod 52 A driving hand wheel 58 is provided, and an array of anti-skid grooves 59 are provided on the outer wall of the driving hand wheel 58.

[0031] By adopting the above technical solution, when in use, when the first floating plate 43 is damaged and cannot push the sealing slide plate 47 to move up and reset, the insulating paint in the paint touch-up tank 21 will be continuously introduced into the impregnation box 11 and the impregnation frame 12 through the paint touch-up conduit 22, and the introduced excess insulating paint will be discharged from the overflow conduit 112. At this time, the discharged excess insulating paint will fall into the material receiving frame 54 and gradually push the material receiving frame 54 to rotate, thereby driving the L-shaped rotating rod 51 to rotate, and then driving the first wheel 53 to rotate, and further through the transmission skin The belt 57 drives the second wheel 56 to rotate, thereby driving the first rotating rod 52 to rotate, and then driving the sealing rotating plate 55 to rotate, and further sealing the paint touch-up duct 22. During this period, the excess insulating paint that falls into the material receiving frame 54 will fall into the recovery box 61 for storage. During subsequent use, the staff can start the recovery pump 62, so that the collected insulating paint can be introduced into the feed duct 64 through the side connecting pipe 63, and the feed duct 64 can introduce the collected insulating paint into the paint touch-up tank 21 for recycling.
[0032] The warning mechanism 7 includes a second guide rod 71 and a second rotating rod 72. The second guide rod 71 is fixedly inserted on one side of the inner cavity of the recovery box body 61, and the second floating plates 73 are slidably sleeved on the two second guide rods 71. The setting of the second guide rod 71 plays a limiting and guiding role in the movement and adjustment of the second floating plate 73.

The top of the mounting rod 75 is fixedly connected to a driving rack 76, and the second rotating rod 72 is rotatably inserted at the upper end of one side of the recovery box body 61.

Both sides of the driven gear 77 A reset torsion spring 78 is fixedly installed, and the reset torsion spring 78 is movably mounted on the second rotating rod 72. The end of the reset torsion spring 78 is fixedly connected to a movable ring 79, and the movable ring 79 is slidably mounted on the second rotating rod 72. The opposite sides of the movable ring 79 are fixedly installed with first side rods 710 distributed in an array, and a symmetrically distributed fixed ring 711 is fixedly installed on the inner wall of one side of the recovery box 61 close to the movable ring 79. The second rotating rod 72 movably passes through the fixed ring 711, and the opposite sides of the fixed ring 711 are fixedly installed with second side rods 712 distributed in an array. The first side rod 710 and the second side rod 712 are staggered, and the first side rod 710 can movably contact with the second side rod 712.
[0033] By adopting the above technical solution, when in use, if the collected insulating paint is not recycled in time, the gradual accumulation of insulating paint in the recovery box 61 will push the second floating plate 73 to move upward, so that the driving rack 76 can be driven to move upward by installing the plug rod 75, and then the driven gear 77 can be driven to rotate, and further the reset torsion spring 78, the movable ring 79 and the first side rod 710 can be driven to rotate. When the first side rod 710 contacts the corresponding second side rod 712, the corresponding first side rod 710 and the movable ring 79 will be restricted from rotating, so that the corresponding reset torsion spring 78 can be twisted, and as the reset torsion spring 78 is twisted, the first side rod 710 will slide along the end of the corresponding second side rod 712, so that It is enough to drive the two movable rings 79 and the first side rod 710 to move towards each other, and when the opposite ends of the first side rod 710 and the corresponding second side rod 712 are in the same plane, the reset torsion spring 78 will drive the corresponding movable ring 79 and the first side rod 710 to rotate again and move back to back when the first side rod 710 and the corresponding second side rod 712 are misaligned, and then the above steps will be repeated, so that the first side rod 710 can intermittently hit the second side rod 712 and intermittently emit a collision warning sound, thereby reminding the staff that the insulating paint in the recovery box 61 will overflow, and then reminding the staff to recycle and reuse the collected insulating paint in time, further avoiding the waste of collected insulating paint.
[0034] Working principle: When in use, the multi-stage electric push rod 14 is started and the blocking pipe cover 24 is removed, and then the multi-stage electric push rod 14 will drive the sealing top cover 15 to move upward, thereby driving the impregnation material frame 16 to move upward, until the impregnation material frame 16 moves to the highest point, the multi-stage electric push rod 14 is closed and a proper amount of insulating paint is introduced into the impregnation box 11 and the paint repair tank 21, and then the blocking pipe cover 24 is reset and a transformer to be impregnated with an appropriate amount of insulating paint is inserted into the impregnation material frame 16, and then the multi-stage electric push rod 14 is started again, so that the sealing top cover 15 can be driven to move downward, and then the impregnation material frame 16 can be driven to move downward, and further the transformer to be impregnated with insulating paint can be driven downward, until the sealing gasket 17 contacts the impregnation box 11 and is squeezed and deformed, and the multi-stage electric push rod 14 is closed. At this time, the transformer to be impregnated with insulating paint will be immersed in the insulating paint in the impregnation box 11, and the lead-out wire of the transformer to be impregnated with insulating paint will be outside the insulating paint;
[0035] Then, the vacuum pump body 32 is started, so that the air at the upper end of the inner cavity of the impregnation box body 11 and the impregnation frame body 12 can be sucked into the air outlet duct 34 through the air inlet duct 33 and introduced into the upper end of the inner cavity of the paint touch-up tank body 21 by the air outlet duct 34, so that the space at the upper end of the paint touch-up tank body 21 can be pressurized. During this period, the air pressure balance pipe 25 can balance the air pressure inside it. When the inner cavity of the impregnation box body 11 and the impregnation frame body 12 is evacuated into a vacuum state, the vacuum pump body 32 is closed and the impregnation operation of the transformer to be impregnated with insulating paint is continued. After the corresponding transformer insulating paint impregnation operation is completed, the multi-stage electric push rod 14 is started, so that the impregnation material frame 16 and the transformer impregnated with insulating paint can be driven to move upward. At this time, the insulating paint liquid level in the impregnation box body 11 will drop, and then the reset spring 44 will push The first floating plate 43 moves downward, thereby being able to drive the sealing plate 47 to move downward through the L-shaped connecting rod 46, and when the sealing plate 47 is misaligned with the paint touch-up duct 22, the paint touch-up duct 22 will no longer be blocked, and at this time, the insulating paint stored in the paint touch-up tank 21 will be conveniently introduced into the paint touch-up duct 22 under pressure and introduced into the impregnation box 11 and the impregnation frame 12 by the paint touch-up duct 22, and as the insulating paint liquid level in the impregnation box 11 and the impregnation frame 12 rises, the first floating plate 43 will be pushed upward again, thereby being able to drive the L-shaped connecting rod 46 and the sealing plate 47 to move upward again and squeeze the return spring 44 again, until the sealing plate 47 blocks the paint touch-up duct 22 again, the insulating paint replenishing operation will be stopped, and then the above steps will be repeated to carry out the subsequent impregnation operation of the transformer to be impregnated with insulating paint;
[0036] During this period, when the first floating plate 43 is damaged and cannot push the sealing slide plate 47 to move up and reset, the insulating paint in the paint repair tank 21 will be continuously introduced into the impregnation box 11 and the impregnation frame 12 through the paint repair conduit 22, and the introduced excess insulating paint will be discharged from the overflow conduit 112. At this time, the discharged excess insulating paint will fall into the material receiving frame 54 and gradually push the material receiving frame 54 to rotate, thereby driving the L-shaped rotating rod 51 to rotate, and then driving the first wheel 53 to rotate, and further driving the transmission belt 57 to drive The second wheel disc 56 rotates, thereby driving the first rotating rod 52 to rotate, and then driving the sealing rotating plate 55 to rotate, and further blocking the paint repair conduit 22. During this period, the excess insulating paint falling into the material receiving frame 54 will fall into the recovery box 61 for storage. During subsequent use, the staff can start the recovery pump 62, so that the collected insulating paint can be introduced into the material delivery conduit 64 through the side connecting pipe 63, and the collected insulating paint can be introduced into the paint repair tank 21 by the material delivery conduit 64 for recycling;
[0037] If the collected insulating paint is not recycled in time, the gradual accumulation of insulating paint in the recovery box 61 will push the second floating plate 73 to move upward, so that the driving rack 76 can be driven upward by the installation plug rod 75, and then the driven gear 77 can be driven to rotate, and further the reset torsion spring 78, the movable ring 79 and the first side rod 710 can be driven to rotate. When the first side rod 710 contacts the corresponding second side rod 712, the corresponding first side rod 710 and the movable ring 79 will be restricted from rotating, so that the corresponding reset torsion spring 78 can be twisted, and as the reset torsion spring 78 is twisted, the first side rod 710 will slide along the end of the corresponding second side rod 712, so that the two movable The ring 79 and the first side rod 710 move towards each other, and when the first side rod 710 and the corresponding second side rod 712 are in the same plane, the reset torsion spring 78 will drive the corresponding movable ring 79 and the first side rod 710 to rotate again and move back to back when the first side rod 710 and the corresponding second side rod 712 are misaligned, and then the above steps will be repeated, so that the first side rod 710 can intermittently hit the second side rod 712 and intermittently emit a collision warning sound, thereby reminding the staff that the insulating paint in the recovery box 61 will overflow, and then reminding the staff to recycle and reuse the collected insulating paint in time, further avoiding the waste of collected insulating paint.
