Description

Technical Field

[0001] The invention relates to the technical field of power busbar insulation processing, in particular to power busbar insulation processing equipment. Background Art

[0002] The power bus is a conductive device used for power distribution and is widely used in substations, industrial equipment and building power supply systems. It is usually made of copper or aluminum bars and can efficiently transmit large currents. Since the power bus needs to carry higher voltages and currents during operation, it must be insulated to prevent short circuits and leakages and to improve the safety and reliability of the system. At present, the insulation method of the power bus is usually wrapped with heat shrink tubing. This method involves putting a heat shrink tubing on the surface of the busbar and heating it with the help of a hot air gun or a heating furnace to shrink the heat, thereby tightly wrapping the conductor surface to form a stable insulation layer. This can not only effectively prevent electric shock accidents, but also enhance the corrosion resistance and environmental adaptability of the busbar; when performing insulation treatment, the surface of the power busbar conductor must be thoroughly cleaned to remove oil stains, oxide layers and other attached impurities to improve the adhesion of the insulating material and ensure the long-term stability of the insulating layer.

[0003] The traditional cleaning method usually uses a friction plate to rub the outer wall of the busbar conductor to mechanically remove surface attachments. However, in the design of high-current aluminum busbars, in order to optimize the heat dissipation performance, grooves (called heat dissipation grooves or guide grooves) are usually opened on the surface of the aluminum core. The main function of these groove structures is to increase the surface area of ​​the conductor to optimize the heat dissipation performance, and adjust the current distribution to reduce the skin effect. The existing friction plate cleaning method can only effectively remove the attachments on the outer wall of the busbar, but cannot penetrate into the heat dissipation groove. Although there are some solutions that use grinding belts to treat the surface of the power busbar, the grinding belt is only attached and pressed against the outside of the conductor. Its cleaning range is mainly concentrated on the flat part of the busbar, and it is also impossible to penetrate into the groove for effective cleaning, resulting in the dirt, oxide layer and impurities on the wall of the heat dissipation groove cannot be completely cleaned, affecting the adhesion of the insulation layer. Since the heat shrink tube is mainly fixed by close fitting, the uncleaned attachments will reduce the fixing reliability of the heat shrink tube, resulting in poor fixation of the insulating sleeve on the surface of the busbar conductor, and easy sliding and dislocation, thereby affecting the insulation performance and safety. Summary of the invention

The surface cleaning parts 41 and the directional cleaning parts 42 are combined and operated synchronously with each other. The surface cleaning part 41 includes an installation box 411 fixedly connected to the inner wall of the annular carrier 3 and close to the center side opening of the annular carrier 3. The installation box 411 is symmetrically slidable. There are two sliding blocks 412 in dynamic connection, and a limit spring is commonly fixedly connected between the sliding block 412 and the mounting box 411, one end of the sliding block 412 away from the mounting box 411 is fixedly connected to a spring telescopic rod 413, one end of the two spring telescopic rods 413 away from the sliding block 412 is commonly fixedly connected to a polishing plate 414, the left end face of the polishing plate 414 is fixedly connected to a guide plate, the guide plate comprises a transverse section and an inclined section fixedly connected to the left part of the transverse section, and a driving member 44 for driving the polishing plate 414 to reciprocate is arranged on the left part of the annular carrier 3.

[0033] See also Figure 4 and Figure 6 The driving member 44 includes a swivel ring 441 rotatably connected to the left part of the annular carrier frame 3. The outer wall of the swivel ring 441 and the outer wall of the annular carrier frame 3 are hinged with an electric telescopic rod 442 through an ear block.

[0034] First, the power bus conductor is passed through the annular carrier frame 3 and placed on the U-shaped carrier seat 6 by manual or external lifting claws. The two ends of the power bus conductor are respectively placed at the notch positions on the upper part of the U-shaped carrier seat 6. At the same time, the right end of the power bus conductor touches the limit baffle. The electric slider 22 is initially located at the left position of the guide groove 21. When the power bus passes through the annular carrier frame 3 from left to right, its right end touches the inclined section of the guide plate, and then presses the guide plate to move. The guide plate then drives the polishing plate 414 to move, ensuring that the polishing plate 414 can be located at the outer wall of the power bus conductor, and then the polishing plate 414 is pressed against the outer wall of the power bus under the push of the spring telescopic rod 413.

[0035] Then, the electric telescopic rod 442 is controlled to repeatedly extend and shorten, and the electric slider 22 is controlled to move slowly to the right. When the electric telescopic rod 442 is extended, the swivel ring 441 is pushed to rotate, and when it is contracted, the swivel ring 441 is pulled to rotate in the other direction. During the reciprocating rotation of the swivel ring 441, the bar frame 445 is driven to move back and forth. The bar frame 445 then drives the lever to move back and forth through the lever column 444, and the lever plate 443 then drives the polishing plate 414 to move back and forth. The polishing plate 414 then drives the sliding block 412 to move back and forth in the installation box 411 through the spring telescopic rod 413; the electric slider 22 then indirectly drives the polishing plate 414 as a whole to move slowly to the right through the annular carrier frame 3, so that it can move along the outer wall of the power bus conductor, rub and clean the outer surface of the power bus conductor, and remove attached impurities.

[0036] When the second rotating ring 441 rotates in the clockwise direction, the four polishing plates 414 move horizontally in the clockwise direction at the same time. Conversely, when the second rotating ring 441 rotates in the counterclockwise direction, the four polishing plates 414 move horizontally in the counterclockwise direction at the same time.

[0037] See also Figure 2 , Figure 3 and Figure 7 In this embodiment, the directional cleaning part 42 includes a slip ring 421 fixedly connected to the inner wall of the annular carrier 3 through a fixing rod, a sliding rod 422 slidably connected to the slip ring 421, an arc seat 423 fixedly connected to the sliding rod 422 at one end close to the center of the annular carrier 3, two arc expansion plates 424 symmetrically hinged on the arc seat 423, and a grinding belt group arranged on the surface cleaning part 41, the arc seat 423 is symmetrically embedded and fixedly connected with a rotating column, the arc expansion plate 424 is rotatably connected to the rotating column, and a torsion spring is fixedly connected between the arc expansion plate 424 and the rotating column, and the arc seat 423 and the arc expansion plate 424 arc The shape cooperates and then triggers the grinding belt group to expand and fit completely along the wall path of the power bus heat dissipation slot to facilitate cleaning without dead angles. A push member 43 for pressing the slide bar 422 to move toward the center of the annular carrier frame 3 is provided between the right part of the circular inner wall of the annular carrier frame 3 and the slide bar 422. A plurality of grooves corresponding to the slide bar 422 are equidistantly provided on the circular inner wall of the annular carrier frame 3. A return spring 427 is fixedly connected between the groove and the end of the slide bar 422. Two limit rods 7 for limiting the arc-shaped expansion support plate 424 are symmetrically fixedly connected to the outer wall of the slide bar 422. The ends of the two arc-shaped expansion support parts that are away from each other are both rotatably connected with rollers.

[0038] See also Figure 5 , Figure 6 and Figure 7The grinding belt group includes a reel 425 and a polishing belt 426. A through groove for installing the reel 425 is provided on the polishing plate 414. A rotating shaft is connected between the left and right groove walls of the through groove for common rotation. The reel 425 is fixedly connected to the outside of the rotating shaft. A torsion spring is fixedly connected between the reel 425 and the through groove. A polishing belt 426 is wound around the outside of the reel 425. One end of the polishing belt 426 away from the reel 425 is fixedly connected to one side end surface of the polishing plate 414 close to the center of the annular carrier frame 3. A rectangular through groove 5 is provided on the polishing plate 414 for the arc-shaped expansion plate 424 to extend into. The arc-shaped expansion plate 424 extends into the rectangular through groove 5 and touches the polishing belt 426.

[0039] See also Figure 2 and Figure 3 The top moving member 43 includes a swivel ring 431 fixedly and rotatably connected to the inner wall of the annular carrier frame 3 and a matching column 432 fixedly connected to the right end face of the sliding rod 422. A plurality of arc-shaped protrusions 433 corresponding to and used for matching with the matching column 432 are fixedly connected to the inner wall of the circumference of the swivel ring 431 at equal intervals. The arc-shaped protrusion 433 is provided with an arc-shaped groove on one side close to the center of the swivel ring 431.

[0040] After the power bus conductor passes through the center of the annular support frame 3 and is placed on the U-shaped support seat 6, the swivel ring 431 is manually turned to rotate, and the swivel ring 431 then drives the arc-shaped protrusion 433 to move. During the movement of the arc-shaped protrusion 433, its arc surface contacts the matching column 432, and then pushes the matching column 432 toward the center of the annular support frame 3. (After the arc-shaped protrusion 433 pushes the matching column 432 to move to the longest stroke, the arc-shaped protrusion 433 will drive the arc-shaped groove to contact the matching column 432. The outside of the column 432 ensures the stability between the arc-shaped protrusion 433 and the matching column 432 after rotation), the matching column 432 then drives the slide bar 422 to move synchronously, and the slide bar 422 drives the arc-shaped seat 423 to move toward the center of the annular support frame 3. At the same time, the slide bar 422 pulls the reset spring 427 to gradually stretch, and the arc-shaped seat 423 then drives the arc-shaped expansion plate 424 to move toward the center of the annular support frame 3, and the arc-shaped expansion plate 424 touches the polishing belt 426 again.

[0041] Then the polishing belt 426 is pushed into the power bus conductor heat dissipation groove (hereinafter referred to as the conductor heat dissipation groove), and then the arc expansion plate 424 pushes the polishing belt 426 to touch the wall of the conductor heat dissipation groove, and then rotates along the arc surface of the conductor heat dissipation groove, and the corresponding two arc expansion plates 424 rotate in opposite directions around the hinge with the arc seat 423 until the arc expansion plate 424 touches the corner of the conductor heat dissipation groove, at this time, the arc expansion plate 424 abuts against the limit rod 7, and the arc seat 423 touches The polishing belt 426 touches the middle part of the arc-shaped wall of the conductor heat dissipation groove. The arc formed by the two arc-shaped expansion plates 424 and the arc-shaped seat 423 after being fully rotated and expanded is the same as the arc of the arc-shaped wall of the conductor heat dissipation groove, so that the polishing belt 426 completely fits along the groove wall path of the conductor heat dissipation groove; (in the process of the polishing belt 426 being pushed and extended into the conductor heat dissipation groove by the arc-shaped expansion plate 424, the polishing belt 426 will be pulled and then pull the reel 425 to rotate, so that the reel 425 will release the polishing belt 426 synchronously).

[0042] The polishing plate 414 reciprocates laterally and drives the polishing belt 426 to reciprocate, so that the polishing belt 426 moves in the conductor heat dissipation groove, thereby cleaning the inner wall of the conductor heat dissipation groove where it is polished. The polishing plate 414 moves laterally with the annular carrier 3 and drives the polishing belt 426 to move synchronously. The polishing belt 426 then moves laterally from left to right to clean the conductor heat dissipation groove in turn. The cleaned impurities are in the conductor heat dissipation groove. Since the processing table 1 is in an inclined state with the left side higher and the right side lower, the cleaned impurities will automatically roll out to the right under the action of the slope.

[0043] After the surface wall of the power bus conductor is gradually cleaned without dead corners, the swivel ring 431 is rotated in the opposite direction, and the swivel ring 431 then drives the arc-shaped protrusion 433 to rotate and separate from the matching column 432, and then the reset spring 427 is reset and contracted to pull the slide bar 422 to move away from the center of the annular support frame 3, and the slide bar 422 then drives the arc-shaped expansion plate 424 to move synchronously through the arc seat 423, so that the arc-shaped expansion plate 424 is gradually moved out of the conductor heat dissipation groove, and the arc-shaped expansion plate 424 gradually reduces the pushing of the polishing belt 426, and the reel 425 gradually winds and retracts the polishing belt 426. When the arc seat 423 drives the arc-shaped expansion plate 424 to move into the rectangular through groove 5, the arc-shaped expansion plate 424 is reversed and reset under the action of the torsion spring until the arc-shaped expansion plate 424 rotates to the initial position state toward the center of the annular support frame 3.

[0044] Finally, the heat shrink tube is put on the outside of the power bus conductor, and then the heat shrink tube is heated in turn through thermal risk to shrink it, and then wrapped around the outside of the power bus conductor, and then the power bus is lifted and moved to the left to be pulled out and removed, and then the electric slider 22 is controlled to move to the left and reset to the left part of the guide groove 21, that is, the initial position.

[0045] During operation, first, the power bus conductor is passed through the annular carrier frame 3 and placed on the U-shaped carrier seat 6. At this time, the polishing plate 414 in the surface cleaning part 41 touches the outer wall of the power bus conductor. Then, the directional cleaning part 42 in the multi-faceted cleaning mechanism 4 is manually driven to operate, so that the polishing belt 426 in the directional cleaning part 42 enters the heat dissipation groove on the power bus conductor. Then, the electric slider 22 is controlled to gradually move to the right along the guide groove 21. The electric slider 22 then drives the annular carrier frame 3 to move synchronously. The annular carrier frame 3 then drives the multi-faceted cleaning mechanism 4 to move from left to right to clean the surface of the power bus conductor. After cleaning, the heat shrink tube is put on the outside of the power bus conductor, and then heated by a hot air gun to shrink the heat shrink tube and cover the outside of the power bus conductor.
