When the wiring on the copper busbar needs to be replaced, inspected or adjusted, the operator often needs to spend a lot of time and energy to remove these insulation devices. The frequent disassembly and installation of insulation devices not only increases maintenance costs, but also reduces work efficiency. This inconvenience is particularly prominent in the case of emergency repairs or quick replacement of wiring.
[0004] To this end, we propose an insulation device for busbars. Utility Model Content

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings. Example 1
[0028] Reference Figure 1-4 , which is the first embodiment of the utility model, provides an insulation device for a busbar, which includes a plurality of insulation components 1 and two blocking blocks. The plurality of insulation components 1 are connected end to end in a row, and the two connected insulation components 1 are detachably connected. The two blocking blocks are respectively installed at the outward ends of the insulation components 1 on both sides. The insulation device is assembled by connecting a row of a plurality of insulation components 1 end to end. According to actual use requirements, a corresponding number of insulation components 1 can be selected and assembled together for use, which is adaptable to different use environments and is more flexible to use.
[0029] The insulation assembly 1 includes a U-shaped frame 11. Fixing holes 14 are welded to the bottom of each of the four corners of the U-shaped frame 11. Bolts pass through the fixing holes 14 to fix the insulation assembly 1. The top of the U-shaped frame 11 is provided with a mounting cavity 12. Switch structures 2 are rotatably mounted on both sides of the mounting cavity 12. At the same time, the two switch structures 2 are arranged in an opposing state.
[0030] The switch structure 2 includes a rotating column 21 rotatably installed inside the installation cavity 12. The outer wall of the rotating column 21 is covered with a rotating plate 22. A horizontal box 25 is fixed to the top of the installation cavity 12, and a wire cavity 26 is opened in the middle of the horizontal box 25 away from the rotating plate 22.
[0031] Through the installation cavity 12 and the rotating plate 22 and the horizontal box 25 rotatably installed on both sides of the installation cavity 12, the rotating plate 22 drives the horizontal box 25 to rotate in an openable state. When wiring is required, the horizontal box 25 is moved out from the inside of the installation cavity 12, and the copper bus can be touched through the installation cavity 12 to perform wiring operations. There is no need to assemble and disassemble the entire device, which is convenient to use and effectively improves work efficiency. In addition, the independent structure is set up, and the corresponding insulating component 1 can be operated for which wiring is required. The other insulating components 1 are still in an insulating protection state to improve insulation.
[0032] The four corner ends of one side of the U-shaped frame 11 are each provided with a connecting hole 13, and a magnet block is installed inside the connecting hole 13. The four corner ends of the other side of the U-shaped frame 11 are each welded with an iron column 15, and the iron column 15 and the opposite surfaces of the magnet block are magnetically attracted. The process of splicing the two insulating components 1 together is as follows: the iron column 15 on one insulating component 1 enters the interior of the connecting hole 13 on the other insulating component 1. At this time, the iron column 15 will contact the magnet block inside the connecting hole 13. The magnetic attraction between the four iron columns 15 and the four magnet blocks will detachably connect the two insulating components 1 together. The magnetic connection and fixation facilitate the assembly and disassembly of the two insulating components 1, which is very fast and easy to use.
[0033] Magnetic blocks are embedded on both sides of the opposite surfaces of the two horizontal boxes 25, and the opposite surfaces of the magnetic blocks on both sides are in a magnetic adsorption state. When the two horizontal boxes 25 are in a close state, the magnetic blocks installed on both sides will be in a magnetic adsorption state, thereby fixing the two horizontal boxes 25, preventing the two horizontal boxes 25 from accidentally rotating due to vibration, and ensuring the shielding effect of the horizontal boxes 25 on the copper busbar.
[0034] A toggle block 24 is fixed to the top of the horizontal box 25 and on a side away from the line cavity 26. The arrangement of the toggle block 24 is more conducive to toggling the horizontal box 25 to rotate outward.
[0035] During use, the insulation device is assembled by connecting a row of multiple insulation components 1 end to end, and two blocking blocks are respectively installed at the outward ends of the insulation components 1 on both sides. Then, the assembled insulation device is covered with the busbar and the insulation device is fixed;
[0036] When wiring is required, the rotating plate 22 is moved outward by the toggle block 24, and the two rotating plates 22 rotate toward both sides. When the two rotating plates 22 are placed flat toward both sides, the installation cavity 12 is in an open state, that is, the wiring port of the copper busbar is exposed, and the wiring operation can be directly contacted with the copper busbar through the installation cavity 12. After the wiring is completed, the rotating plate 22 is rotated in the opposite direction, and the two horizontal boxes 25 are brought together to confine the wires in the inner cavity of the wire cavity 26, completing the wiring. Example 2
[0037] Reference Figure 1-4 , which is the second embodiment of the present utility model, is different from the first embodiment in that:
[0038] A transmission plate 272 is slidably installed inside the horizontal box 25, and a linkage bar 273 is fixed on the side of the transmission plate 272 close to the line cavity 26, and one end of the linkage bar 273 is located inside the line cavity 26. A connecting port 28 is provided on the inner wall surface of the line cavity 26 for the linkage bar 273 to pass through, and a clamping block 27 is fixed on the end of the linkage bar 273 located inside the line cavity 26.
[0039] A sliding hole is provided at one end of the transmission plate 272, and the transmission plate 272 is slidably connected to a guide rod 271 through the sliding hole. The guide rod 271 is fixed to the inside of the horizontal box 25. A threaded hole is provided at the other end of the transmission plate 272, and a screw rod 274 is threadedly installed on the transmission plate 272 through the threaded hole. One end of the screw rod 274 is rotatably installed on the inner wall surface of the horizontal box 25 through a bearing, and the other end of the screw rod 274 is located outside the horizontal box 25. A knob is provided at the other end of the horizontal box 25 to clamp the wire between the clamping blocks 27 on both sides for fixing, which helps to prevent the wire from falling off the copper bus when being dragged, thereby improving the stability of the power.
[0040] The bottom end of the rotating plate 22 is provided with a semicircular edge 23 .
[0041] During use, when the wire is located inside the wire cavity 26, the screw rod 274 is driven to rotate. Under the threaded transmission action of the screw rod 274 and the transmission plate 272, the clamping block 27 is driven to move toward the wire cavity 26 through the linkage bar 273, so that the wire can be clamped between the clamping blocks 27 on both sides for fixation.
[0042] The remaining structures are the same as those of Example 1.
[0043] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
