Description

Technical Field

[0001] This utility model relates to the field of impregnation technology, and specifically to an impregnation device. Background Technology

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. During the production process, in order to improve its insulation, transformers usually need to undergo an impregnation process.

[0003] When currently impregnating transformers with varnish, a certain amount of liquid is first added to the impregnation tank. Then, personnel place the transformers one by one onto the screen tray. The screen tray is then lowered gradually by the lifting mechanism inside the impregnation tank, so that the screen tray and the transformer are completely immersed in the impregnation liquid. After a certain impregnation time, personnel control the lifting mechanism to move the screen tray upward, so that the screen tray is completely exposed above the surface of the impregnation liquid. Then, personnel remove the transformers one by one from the screen tray.

[0004] Although the above equipment can perform varnish impregnation on transformers, it is too cumbersome because personnel need to place each transformer on a screen for immersion and remove them one by one. This process also reduces the workload of personnel. Utility Model Content

[0005] In view of this, the present invention provides a coating impregnation device, which can lift and transfer the screen frame to the next process, thereby avoiding the need for personnel to remove and transfer the transformers in the screen frame one by one.

[0006] To solve the above-mentioned technical problems, this utility model provides a coating impregnation device, including a coating impregnation tank and a placement screen frame. Placement blocks are provided on both sides of the placement screen frame. A lifting assembly is provided inside the coating impregnation tank. The lifting assembly includes guide grooves and slide grooves slidably disposed on both sides inside the coating impregnation tank. A placement frame is slidably disposed between the guide grooves and slide grooves. A placement slot is provided on the placement frame, and the placement blocks are located within the placement slots. That is, personnel evenly place the transformer within the screen frame, and utilize the placement blocks on both sides of the screen frame to align with the placement slots of the placement frame in the lifting assembly to achieve rapid positioning. The lifting assembly drives the placement frame to move downwards along the guide groove and slide, immersing the screen frame in the impregnation tank liquid. The impregnation liquid permeates evenly through the holes in the screen frame, covering the transformer surface and completing the impregnation. After impregnation, the lifting assembly reverses its rotation, moving the screen frame upwards above the liquid surface. Excess paint on the transformer surface flows back into the impregnation tank through the screen holes, while gravity accelerates the draining process, preventing the paint film from flowing or accumulating. After draining, personnel grab the screen frame as a whole and transfer it to the next process, eliminating the need to remove the transformers one by one, significantly shortening the operation time.

[0007] The lifting assembly also includes a lead screw installed in the slide groove, which is threaded to one side of the placement frame; that is, the lead screw is used to drive the placement frame to move along the slide groove.

[0008] The lifting assembly also includes a sliding column disposed in the guide groove, which extends through one side of the placement frame; that is, the sliding column is used to provide stability for the placement frame during movement.

[0009] The lifting assembly also includes a motor located at the bottom of the impregnation tank, with the motor's output shaft connected to one end of the lead screw; that is, the motor provides rotation to the lead screw.

[0010] The placement frame is equipped with a locking component, which includes a through groove 1 and a through groove 2, both of which are set on both sides of the inner wall of the placement groove. A limit strip is slidably installed in the through groove 1. The limit strip passes through the interior of the placement block and enters the interior of the through groove 2. That is, the limit strip passes through the interior of the placement block along the direction of the through groove 1 and enters the through groove 2, thereby achieving the limitation of the placement block.

[0011] The locking assembly also includes a threaded rod disposed in the through groove, and the threaded rod is threaded with the inside of the limit bar; that is, the threaded rod can drive the limit bar to move.

[0012] The locking assembly also includes inner grooves on both sides of the placement frame. The inner grooves are located at the side ends of the through groove one. A worm gear is installed in the inner groove, and the side end of the worm gear is connected to one end of the threaded rod. A worm is vertically installed in each inner groove, and the worm meshes with the worm gear. A drive button is installed on both sides of the placement frame, and the drive button is connected to the end of the threaded rod. That is, the worm gear and worm have a self-locking function, which can effectively limit the rotation of the threaded rod.

[0013] The upper surface of the impregnation tank is fitted with a sealing door via a hinge; that is, the sealing door provides the impregnation tank with airtightness.

[0014] The outer surface of the impregnation tank is equipped with a support frame, and four support columns are provided at the bottom of the support frame; that is, the support columns provide stable support for the impregnation tank above the support frame.

[0015] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0016] 1. First, the rotation of the motor drives the lead screw to rotate, indirectly connecting the external thread of the lead screw with the thread at one end of the placement frame. This allows the placement frame to slide along the direction of the slide groove and guide groove, providing mobility for the placement screen frame and completely exposing the transformer, achieving a draining effect. After the transformer is drained, personnel lift the placement screen frame and transfer it to the next process, thus avoiding the need for personnel to remove and transfer each transformer from the placement screen frame one by one.

[0017] 2. First, personnel place the transformers one by one onto the screen frame. Then, by aligning the placement blocks on both sides of the screen frame with the placement slots on both sides of the frame, the screen frame is initially positioned. The drive button drives the worm gear, causing it to rotate. This indirectly causes the worm gear to mesh with the worm wheel, which in turn drives the threaded rod to rotate. The threaded rod then moves the limiting strip along the direction of through slot one, indirectly allowing the limiting strip to pass through the placement block and enter through slot two, thus fixing the screen frame and providing a limiting function. This prevents the buoyancy of the impregnation liquid in the impregnation tank from affecting the placement of the screen frame. Attached Figure Description

Figure 1-5 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0020] like Figure 1-5 As shown: This embodiment provides a coating impregnation device, including a coating impregnation tank 100 and a placement screen frame 104. Placement blocks 106 are provided on both sides of the placement screen frame, and the placement blocks 106 are fixedly installed on both sides of the placement frame by welding. A lifting assembly 200 is provided inside the coating impregnation tank 100. The lifting assembly 200 includes a guide groove 204 and a sliding groove 202 slidably disposed on both sides inside the coating impregnation tank 100. A placement frame 203 is slidably disposed between the guide groove 204 and the sliding groove 202. A placement groove 105 is provided on the placement frame 203, and the placement blocks 106 are located in the placement groove 105. First, a certain amount of coating liquid is added to the coating impregnation tank 100. Then, the transformers are placed one by one on the placement screen frame 104. The placement blocks 106 on both sides of the placement screen frame 104 are aligned with the sides of the placement frame 203. The placement slot 105 provides initial positioning for the placement screen frame 104. As the lifting component 200 operates, the placement frame 203 carries the placement screen frame 104 into the impregnation tank 100. Impregnation liquid flows in through the holes of the placement screen frame 104, allowing for uniform impregnation of the transformer. After impregnation, the lifting component 200 moves the placement frame 203 upward, causing the placement screen frame 104 to move upward, completely exposing the transformer and achieving a draining effect. Once the transformer is drained, personnel lift the placement screen frame 104 and transfer it to the next process, thus avoiding the need for personnel to remove and transfer each transformer from the placement screen frame 104 individually. Lifting component 200 Figure 2 and Figure 3 As shown, The lifting assembly 200 also includes a lead screw 201 disposed in the slide groove 202. The lead screw 201 is installed in the slide groove 202, so that the lead screw 201 can rotate in the slide groove 202. The lead screw 201 is threaded to one side of the placement frame 203, and the external thread of the lead screw 201 is threaded to the internal thread on one side of the placement frame 203, so that the placement frame 203 can be driven to slide along the direction of the slide groove 202. The lifting assembly 200 also includes a sliding column 205 disposed in the guide groove 204. The sliding column 205 is fixedly installed in the guide groove 204 by welding. The sliding column 205 passes through one side of the placement frame 203, thereby providing stability for the movement of the placement frame 203. The lifting assembly 200 also includes a motor 206 disposed on the bottom of the impregnation tank 100. The motor 206 is fixedly installed on the bottom of the impregnation tank 100 by bolts, and the output shaft of the motor 206 is connected to one end of the lead screw 201. First, the rotation of the motor 206 drives the lead screw 201 to rotate, indirectly connecting the external thread of the lead screw 201 to one end of the placement frame 203. This allows the placement frame 203 to slide along the direction of the slide groove 202 and the guide groove 204, while providing mobility for placing the screen frame 104.

[0021] Locking component 300 Figure 5 As shown, A locking component 300 is provided on the placement frame 203. The locking component 300 includes a first through groove 301 and a second through groove 304, both of which are provided on both sides of the inner wall of the placement groove 105. The length of the second through groove 304 is less than the length of the first through groove 301. A limit strip 302 is slidably provided in the first through groove 301. The limit strip 302 passes through the interior of the placement block 106 and enters the interior of the second through groove 304, thereby providing a limiting function for placing the screen frame 104, thus preventing the buoyancy of the impregnation liquid in the impregnation tank 100 from affecting the placement of the screen frame 104. The locking assembly 300 also includes a threaded rod 303 disposed in the through groove 301. The threaded rod 303 is mounted on the side wall of the through groove 301 by a bearing, so that the threaded rod 303 can rotate in the through groove 301. The threaded rod 303 is threaded with the limiting strip 302. During the rotation of the threaded rod 303, it can drive the limiting strip 302 to move along the direction of the through groove 301. Thus, the through groove 301, the through groove 304, and the limiting strip 302 adopt a rectangular structure, thereby preventing the threaded rod 303 from rotating while carrying the limiting strip 302. The locking assembly 300 also includes inner grooves 308 that are provided on both sides of the placement frame 203. The inner grooves 308 are located at the side ends of the through groove 301. A worm gear 307 is provided in the inner groove 308. The side end of the worm gear 307 is connected to one end of the threaded rod 303. A worm 306 is vertically provided in both inner grooves 308. The worm 306 is meshed with the worm gear 307. The worm 306 and the worm gear 307 have a self-locking function. A drive button 305 is provided on both sides of the placement frame 203. The drive button 305 is connected to the end of the threaded rod 303. Thus, the drive button 305 provides drive for the worm 306, causing the worm 306 to rotate, indirectly causing the worm 306 to mesh and rotate with the worm wheel 307, causing the worm wheel 307 to drive the threaded rod 303 to rotate, causing the threaded rod 303 to drive the limiting strip 302 to move along the direction of the first through groove 301, indirectly causing the limiting strip 302 to pass through the interior of the placement block 106 and enter the interior of the second through groove 304, thereby fixing the placement screen frame 104; Sealed door 101 Figure 1 As shown, A sealing door 101 is provided on the upper surface of the impregnation tank 100 by means of a hinge, and the sealing door 101 is used to provide a seal for the impregnation tank 100. The outer surface of the paint dipping tank 100 is provided with a support frame 102, and the bottom of the support frame 102 is provided with four support columns 103, which provide support for the paint dipping tank 100. Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0022] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
