Technical Field

[0001] The invention relates to a combined transformer, in particular to a combined transformer, and belongs to the technical field of transformers. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, the secondary coil, and the iron core. The main functions are: voltage conversion, current conversion, impedance conversion, isolation, and voltage stabilization. Currently, most transformer monitoring devices use temperature sensors for measurement and monitoring, and perform simple air temperature monitoring on the transformer installation area to achieve a monitoring purpose for the temperature generated by the transformer. However, the above existing method is not accurate, and it is impossible to perform real-time temperature monitoring of the entire transformer. It is impossible to accurately monitor the temperature changes of various parts of the transformer, and it is impossible to make corresponding processing in a timely manner;

The invention is provided with an extension frame on the surface of the transformer, and a slide groove and a protrusion are opened on the surface of the extension frame. The motor drives the rotating shaft to rotate, the first through hole drives the second gear to rotate, and the second gear rotates in the rolling groove, so that the plug-in board moves in the slide groove, the vertical board moves with the plug-in board, and the temperature monitor on the surface of the vertical board monitors the surface temperature of the transformer, and during the movement of the plug-in board, the push plate holds the force plate, so that the force plate descends";

[0004] The above patent has the following shortcomings: it realizes gear lubrication by delivering lubricating oil through extrusion, but the tank for storing lubricating oil lacks stirring function. If the lubricating oil is stationary for a long time, its activity will be reduced and the oil outlet will be easily blocked, resulting in poor oil delivery effect and failure to meet usage requirements.

[0005] Therefore, it is urgent to make improvements to solve the above-mentioned problems. Summary of the invention

[0006] The object of the present invention is to provide a combined transformer, which provides a stirring rod in an oil storage tank, and connects the driving of the stirring rod to a driven gear. During the rotation of the driven gear, the stirring rod is driven to rotate by the connecting shaft and the spline shaft. The rotation of the stirring rod stirs the lubricating oil in the oil storage tank. At the same time, during the movement of the vertical plate, the abutment shaft moves against the oblique abutment plate, which drives the connecting plate and the stirring rod to move. Then, through the deformation of the elastic structure, the stirring rod and the connecting plate have a reciprocating function. When the stirring rod reciprocates, the stirring of the lubricating oil can be further improved to improve the activity of the lubricating oil. When the connecting plate reciprocates up and down, it drives the piston to reciprocate up and down. The movement of the piston causes the cavity volume in the pump body to increase, forming a negative pressure, thereby attracting liquid to enter and discharge, so that the nozzle can quantitatively transport the lubricating oil for lubrication, effectively solving the problems raised in the above-mentioned background technology.

[0023] The present invention has at least the following beneficial effects:

[0024] 1. When the combined transformer is in use, the vertical plate is driven to move through the transmission cooperation of the driving motor, the transmission gear and the driven gear, and the temperature monitor on the surface of the vertical plate monitors the surface temperature of the combined transformer body.

[0025] 2. The combined transformer is provided with a stirring rod in the oil storage tank, and the driving of the stirring rod is connected to the driven gear. During the rotation of the driven gear, the stirring rod is driven to rotate through the connecting shaft and the spline shaft. The rotation of the stirring rod stirs the lubricating oil in the oil storage tank. At the same time, during the movement of the vertical plate, the abutment shaft moves against the oblique abutment plate, which drives the connecting plate and the stirring rod to move. Then, through the deformation of the elastic structure, the stirring rod and the connecting plate have a reciprocating function.

[0026] 3. When the stirring rod in the combined transformer reciprocates, it can further enhance the stirring of the lubricating oil to improve the activity of the lubricating oil. When the connecting plate reciprocates up and down, it will drive the piston to reciprocate up and down. The movement of the piston causes the cavity volume in the pump body to increase, forming a negative pressure, thereby attracting liquid to enter and discharge, so that the nozzle can quantitatively transport the lubricating oil for lubrication;

[0027] 4. When the stirring rod in the combined transformer reciprocates downward, the opposite poles of the extrusion magnetic head and the magnetic block repel each other, thereby pushing the knocking rod to move outward and squeezing the reciprocating spring. When the stirring rod reciprocates upward, the magnetic block breaks away from the repulsion of the extrusion magnetic head. Through the reciprocating motion of the reciprocating spring, the knocking head reciprocates to knock the oil storage tank, which helps to break the adhesion between materials, reduce the residue on the inner wall of the oil storage tank, and improve the stirring efficiency. When the knocking head reciprocates, it cooperates with the rotation of the stirring rod to knock on multiple positions inside the oil storage tank, thereby improving the cleaning effect.

[0028] 5. When the knocking rod in the combined transformer reciprocates, it contacts the elastic booster in the groove during the movement. The elastic booster will deform due to the pressure and store energy. When the knocking rod continues to move and leaves the elastic booster, the elastic booster will release the stored energy and generate an additional thrust or pull on the knocking rod, thereby increasing the reciprocating speed and knocking force of the knocking rod.

[0040] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0041] like Figure 1 - Figure 6 As shown, the combined transformer provided in this embodiment includes a combined transformer body 1, an extension frame 2 is provided on the surface of the combined transformer body 1, a vertical plate 3 for walking is provided on the extension frame 2, and a temperature monitor 4 is installed on the side of the vertical plate 3 close to the combined transformer body 1; two guide plates 5 distributed up and down are fixedly connected to the side of the vertical plate 3 close to the extension frame 2, and a walking mechanism is provided between the two guide plates 5, and an oil storage tank 11 and an oil delivery mechanism 14 are installed on the upper surface of the top guide plate 5; the walking mechanism includes a driving motor 6 fixedly installed on the lower surface of the top guide plate 5, a transmission gear 7 fixedly installed on the output shaft of the driving motor 6, and a driven gear 8 rotatably installed on the upper surface of the bottom guide plate 5 and meshing with the transmission gear 7. Among them, the surface of the extension frame 2 is provided with a rolling groove 9 meshing with the driven gear 8 and a sliding groove 10 slidingly matched with the two guide plates 5. The vertical plate 3 is driven to move by the transmission cooperation of the driving motor 6, the transmission gear 7 and the driven gear 8, and the temperature monitor 4 on the surface of the vertical plate 3 monitors the surface temperature of the combined transformer body 1. It should be noted that the cross section of the slide groove 10 is T-shaped, and the guide plate 5 can move in the slide groove 10 .

[0042] In addition, the temperature monitor 4 is a conventional device known to the public in the prior art, so its specific structure and working principle will not be described in detail in this article.

[0043] In this embodiment, if Figure 6 As shown, the oil delivery mechanism 14 includes a pump body 1401, two valve tubes 1402 fixedly connected to opposite sides of the pump body 1401, a piston 1403 slidably arranged inside the pump body 1401, and a valve stem 1404 fixedly installed on the upper surface of the piston 1403 and extending to the outside of the pump body 1401. The two valve tubes 1402 are fixedly connected to a connecting tube 1405 at one end away from each other, and one of the connecting tubes 1405 is fixedly connected to the oil storage tank 11, and a nozzle 1407 is detachably installed at the end of the other connecting tube 1405; a check valve plate 1406 is elastically hingedly installed inside the two valve tubes 1402, and a clamp is installed on the outer wall of the top guide plate 5 to fix the connecting tube 1405. Among them, the output end of the nozzle 1407 faces the transmission gear 7 and the driven gear 8, and the nozzle 1407 and the connecting tube 1405 are threadedly connected.

[0044] In this embodiment, the oil delivery mechanism 14 is used to deliver the lubricating oil in the oil storage tank 11, and the controllable up and down reciprocating effect of the piston 1403 is used to deliver the lubricating oil in a quantitative manner. When in use, the movement of the piston 1403 causes the cavity volume in the pump body 1401 to increase, forming a negative pressure, thereby attracting liquid to enter and discharge, so that the nozzle 1407 delivers the lubricating oil in a quantitative manner to perform lubrication work.

[0045] In addition, when the piston 1403 moves up and down, the pressure in the pump chamber in the pump body 1401 will change. When the piston 1403 moves upward, the outlet check valve plate 1406 is closed under the action of its own weight and pressure difference to prevent the liquid in the pump chamber from flowing back. At the same time, the inlet check valve plate 1406 opens under the action of pressure difference to allow the liquid to be sucked into the pump chamber. When the piston 1403 is squeezed inward, the pressure in the pump chamber increases, which causes the inlet check valve plate 1406 to close to prevent the liquid from flowing back. At the same time, the outlet check valve plate 1406 opens to allow the liquid in the pump chamber to be pressed into the connecting pipe 1405 of the outlet.

[0046] In order to improve the activity of the lubricating oil, in this embodiment, Figure 7 As shown, the upper surface of the driven gear 8 is installed with a stirring assembly 12 extending to the inside of the oil storage tank 11, and the stirring assembly 12 includes a telescopically connected stirring rod 1201 and a spline shaft 1202, a connecting shaft 13 is fixedly connected between the spline shaft 1202 and the driven gear 8, the spline shaft 1202 is rotatably connected to the inside of the oil storage tank 11, and the top of the stirring rod 1201 extends to the upper surface of the oil storage tank 11; wherein, the interior of the stirring rod 1201 is hollow, and the interior of the stirring rod 1201 is provided with a spline groove that slides with the spline shaft 1202. The length of the spline groove is adapted to the up and down reciprocating distance of the stirring rod 1201. When the stirring rod 1201 rotates, it can further improve the stirring of the lubricating oil to improve the activity of the lubricating oil.

[0047] Specifically, the oil storage tank 11 is provided with a telescopic hole and a rotating hole on the upper and lower sides respectively, and a rotating hole 51 corresponding to the rotating hole is provided inside the bottom guide plate 5, and the stirring rod 1201 passes through the telescopic hole. Bearings connected to the spline shaft 1202 are installed inside the rotating hole and the rotating hole 51, and the spline shaft 1202 is connected to the connecting shaft 13 through a coupling.

[0048] In order to further improve the activity of the lubricating oil, in this embodiment, Figure 6As shown, an abutment structure 16 is installed between the valve stem 1404 and the stirring rod 1201, and the abutment structure 16 includes a connecting plate 1601 installed between the valve stem 1404 and the stirring rod 1201, a connecting column 1602 fixedly installed on the upper surface of the connecting plate 1601, and an abutment shaft rod 1603 fixedly connected to the connecting column 1602 near the side of the combined transformer body 1, and an oblique abutment plate 17 abutting and cooperating with the abutment shaft rod 1603 is installed on the outer wall of the combined transformer body 1, and the stirring rod 1201 is rotatably connected to the connecting plate 1601. An elastic structure 15 is provided on the outer surface of the top of the stirring rod 1201, and the elastic structure 15 includes a connecting ring 1501 and a reset spring 1502, and the reset spring 1502 is fixedly installed between the upper surface of the oil storage tank 11 and the connecting ring 1501, and the connecting ring 1501 bearing is installed on the outer surface of the stirring rod 1201. By installing the abutment structure 16, not only can the stirring rod 1201 reciprocate up and down, but it can also drive the oil delivery mechanism 14, thereby improving the applicability and linkage of the device. Through the deformation of the elastic structure 15, the stirring rod 1201 and the connecting plate 1601 have a reciprocating function. When the stirring rod 1201 reciprocates, it can further improve the stirring of the lubricating oil to improve the activity of the lubricating oil. When the connecting plate 1601 reciprocates up and down, it will drive the piston 1403 to reciprocate up and down. The movement of the piston 1403 causes the cavity volume in the pump body 1401 to increase, forming a negative pressure, thereby attracting liquid to enter and discharge, so that the nozzle 1407 quantitatively delivers the lubricating oil for lubrication.

[0049] Specifically, the return spring 1502 surrounds the outside of the stirring rod 1201. When the abutting shaft rod 1603 moves, the end of the abutting shaft rod 1603 close to the combined transformer body 1 will contact the oblique abutting plate 17. Under the push of the oblique abutting plate 17, the connecting plate 1601 and the stirring rod 1201 will drop, and the deformation of the abutting structure 16 and the elastic structure 15 can be used to make the stirring rod 1201 reciprocate up and down. When the stirring rod 1201 reciprocates and rotates up and down, the stirring of the lubricating oil can be further improved to improve the activity of the lubricating oil.

[0050] It is understandable that when the stirring rod 1201 stirs up and down in the lubricating oil storage tank 11, it mainly brings the following benefits: Improve the uniformity of mixing: reciprocating stirring can effectively mix the various components in the lubricating oil to ensure that the components are evenly distributed in the lubricating oil, which is crucial to improving the performance and stability of the lubricating oil, because the evenly mixed lubricating oil can better play its lubricating, cooling and cleaning functions. Enhance shear force: reciprocating stirring has good shear force, which is particularly important for the mixing of suspensions and viscous liquids. In the lubricating oil, if there are solid particles or viscous components, reciprocating stirring can effectively disperse them into the base oil to avoid agglomeration and sedimentation. Promote the fluidity of the lubricating oil: by stirring, the movement of the lubricating oil molecules can be accelerated, thereby improving its fluidity. This is very beneficial for the transportation and use of the lubricating oil, and can ensure that the lubricating oil flows smoothly in the mechanical equipment and plays a good lubricating role. Improve the quality of the lubricating oil: reciprocating stirring can also promote the interaction of the various components in the lubricating oil, which is conducive to the chemical reaction (such as the dissolution and dispersion of additives), thereby further improving the quality of the lubricating oil. In addition, stirring can remove bubbles and impurities in the lubricating oil, improving its purity and transparency.

[0051] In order to reduce the residue, in this embodiment, Fig. 9 As shown, a knocking structure 18 is arranged between the stirring rod 1201 and the spline shaft 1202, and the knocking structure 18 includes a knocking rod 1801 which is reciprocatingly arranged inside the stirring rod 1201 and is arranged laterally, a knocking head 1802 which is rollingly installed on the end of the knocking rod 1801 away from the stirring rod 1201, a sealing ring 1803 arranged inside the stirring rod 1201, a reciprocating spring 1804 fixedly installed on the outer wall of the sealing ring 1803, an extrusion head 1805 fixedly installed on the top of the spline shaft 1202, and a magnetic block 1806 which is fixedly installed on the end of the knocking rod 1801 away from the knocking head 1802 and repels the extrusion head 1805.

[0052] Specifically, there are two sealing rings 1803, and the reciprocating spring 1804 is fixedly installed between the two sealing rings 1803, and the reciprocating spring 1804 surrounds the outer surface of the knocking rod 1801. One of the sealing rings 1803 is in sliding contact with the inside of the stirring rod 1201, and the other sealing ring 1803 is fixed to the inside of the stirring rod 1201. The spline groove is provided with an extension groove on one side of the knocking rod 1801 for the reciprocating motion of the knocking rod 1801, and when the knocking head 1802 knocks back and forth, it cooperates with the rotation of the stirring rod 1201 to knock on multiple positions inside the oil storage tank 11, thereby improving the cleaning effect. A booster 1807 is installed in the extension groove. When the knocking rod 1801 reciprocates, it contacts the booster 1807 in the groove during the movement. The booster 1807 will deform due to the pressure, and then store energy. When the knocking rod 1801 continues to move and leaves the booster 1807, the booster 1807 will release the stored energy, generating an additional thrust or pull on the knocking rod 1801, thereby increasing the reciprocating speed and knocking force of the knocking rod 1801. The outer surface of the knocking rod 1801 is threadedly installed with a preload ring 1808 for preloading the reciprocating spring 1804. The preload ring 1808 can adjust the preload force of the reciprocating spring 1804, thereby changing the reciprocating speed and frequency of the knocking rod 1801. At the same time, by adjusting the preload ring 1808, the knocking frequency of the knocking rod 1801 can be flexibly adjusted according to the characteristics of the material in the mixing tank 11 and the mixing requirements, so as to achieve the best mixing effect.

[0053] It can be understood that when the stirring rod 1201 reciprocates downward, the opposite poles of the extrusion head 1805 and the magnetic block 1806 repel each other, thereby pushing the knocking rod 1801 to move outward and squeeze the reciprocating spring 1804. When the stirring rod 1201 reciprocates upward, the magnetic block 1806 breaks away from the repulsion of the extrusion head 1805, and the reciprocating motion of the reciprocating spring 1804 causes the knocking head 1802 to reciprocate and knock on the oil storage tank 11, thereby helping to break the adhesion between materials, reduce the residue on the inner wall of the oil storage tank, and improve the stirring efficiency.

[0054] It should be noted that the knocking head 1802 and the knocking rod 1801 are detachable, and the knocking head 1802 can be disassembled and replaced with a scraper. When the stirring rod 1201 reciprocates downward, the knocking rod 1801 moves outward by squeezing the opposite poles of the magnetic head 1805 and the magnetic block 1806 to repel each other, so that the scraper is against the inner wall of the oil storage tank 11, and the rotation of the stirring rod 1201 is coordinated to scrape off the lubricating oil on the inner wall of the oil storage tank 11.

[0055] like Figure 1 - Fig. 9 As shown, the principle of the combined transformer provided in this embodiment is as follows:

[0056] When the present invention is used, the vertical plate 3 is driven to move by the transmission cooperation of the driving motor 6, the transmission gear 7 and the driven gear 8, and the temperature monitor 4 on the surface of the vertical plate 3 monitors the surface temperature of the combined transformer body 1, and during the rotation of the driven gear 8, the stirring rod 1201 is driven to rotate through the connecting shaft 13 and the spline shaft 1202, and the stirring rod 1201 rotates to stir the lubricating oil in the oil storage tank 11, and at the same time, during the movement of the vertical plate 3, the abutment shaft 1603 moves against the oblique abutment plate 17, which will drive the connecting plate 1601 and The stirring rod 1201 moves, and through the deformation of the elastic structure 15, the stirring rod 1201 and the connecting plate 1601 have a reciprocating function. When the stirring rod 1201 rotates back and forth, it can further improve the stirring of the lubricating oil to improve the activity of the lubricating oil. When the connecting plate 1601 reciprocates up and down, it will drive the piston 1403 to reciprocate up and down. The movement of the piston 1403 causes the cavity volume in the pump body 1401 to increase, forming a negative pressure, thereby attracting liquid to enter and discharge, so that the nozzle 1407 delivers the lubricating oil in a quantitative manner for lubrication.
