[0030] Please refer to Figures 1-4 As shown, this embodiment is an anti-dizziness type pipe busbar clamp, including:

[0031] The pipe busbar clamp part, the pipe busbar clamp part includes an upper bracket 11; a wire clamp 12 is provided at the end of the upper end of the upper bracket 11;

[0032] The upper bracket 11 fixedly installs the wire clamp 12, and the wire clamp 12 is used to clamp and fix the pipe busbar;

[0033] The pipe busbar clamp part further includes a lower bracket 13, side finger-shaped wire clamp aluminum tubes 14, and a middle finger-shaped wire clamp aluminum tube 15; side finger-shaped wire clamp aluminum tubes 14 are provided on both sides of the lower end of the lower bracket 13, and a middle finger-shaped wire clamp aluminum tube 15 is provided at the middle and rear of the lower end of the lower bracket 13;

[0034] The lower bracket 13 structurally fixes the side finger-shaped wire clamp aluminum tubes and the middle finger-shaped wire clamp aluminum tubes, and the side finger-shaped wire clamp aluminum tubes and the middle finger-shaped wire clamp aluminum tubes are used to access and press-connect and limit the shunt conductors;

[0035] The upper part of the inner side of the lower bracket 13 fits the lower part of the front of the upper bracket 11, and the upper part of the front of the lower bracket 13 is circumferentially and equidistantly penetrated through the upper bracket 11 and is provided with a lower locking bolt 17;

[0036] The ends of the wire clamp 12 are symmetrically threaded and penetrated through and provided with upper locking bolts 16;

[0037] The upper locking bolt 16 locks the end of the wire clamp 12 to meet the positioning and fixing of the pipe busbar. The lower locking bolt 17 fixes the upper support 11 and the lower support 13. The threaded connection is conducive to the disassembly and assembly of the structure.

[0038] It also includes an anti-corona and noise reduction part, and the anti-corona and noise reduction part includes an anti-corona cover 21; an end block 23 is movably arranged at the end of the anti-corona cover 21.

[0039] The anti-corona cover 21 can provide anti-corona protection for the pipe busbar, and the end block 23 ensures the installation limitation of the structure of the anti-corona cover 21.

[0040] The movable adjustment part includes a hole block 31, an adjustment threaded column 32 and an adjustment plate 33; the hole blocks 31 are connected to both sides of the end of the anti-corona cover 21. An adjustment plate 33 is arranged on one side of the end block 23, and one end of the adjustment plate 33 is arranged between a group of connected hole blocks 31. One end of the adjustment threaded column 32 passes through the hole block 31 and the adjustment plate 33, and a nut is threadedly arranged at the end of the adjustment threaded column 32.

[0041] The hole block 31 and the adjustment threaded column 32 are used in combination to install and fix the structure of the adjustment plate 33 to meet the structural installation between the anti-corona cover 21 and the end block 23. The nut limits the end of the adjustment threaded column 32. Utilizing the characteristic of threaded rotation, the angle adjustment of the end block 23 can be ensured and the stability of the structure can be guaranteed.

[0042] The adjustment plate 33 is arc-shaped, and the inner side of the adjustment plate 33 is spaced from the outer surfaces of the anti-corona cover 21 and the end block 23.

[0043] The arc-shaped setting is conducive to the connection with the annular groove at the end of the wire clamp 12, and the spaced setting can meet the angle adjustment of the end block 23.

[0044] Working principle: After the upper support 11 and the lower support 13 are attached and locked with the lower locking bolt 17, the pipe busbar to be installed is inserted into the wire clamp 12. At the same time, multiple shunt wires are extended into the side finger-shaped wire clamp aluminum tube 14 and the middle finger-shaped wire clamp aluminum tube 15, and then crimped and limited. During the process of locking the pipe busbar with the wire clamp 12, the port position of the wire clamp 12 is deformed under force. At this time, a force can be applied to the end block 23. The end block 23 and the anti-corona cover 21 are connected by a threaded connection. Under the application of force, the adjustment threaded column 32 drives the end block 23 to rotate at an angle. After the end block 23 is adjusted to an appropriate angle, the end block 23 can be placed into the deformed annular groove at the end of the wire clamp 12, and the undeformed part of the annular groove is placed into the anti-corona cover 21.

[0045] It can meet the fixation of the structure of the anti-corona cover 21, improve the applicability and functionality of the structure, and meet different usage requirements.

[0046] In a specific application, the anti-corona noise reduction part further includes a metal sound insulation felt 22 and an isolation ring 24; the metal sound insulation felt 22 is threadedly arranged on the inner wall of the anti-corona cover 21, and the isolation ring 24 is threadedly arranged on the inner wall of the metal sound insulation felt 22;

[0047] The metal sound insulation felt 22 improves the sound insulation effect of the anti-corona cover 21 and achieves a noise reduction effect. The isolation ring 24 isolates the metal sound insulation felt 22 to prevent the tube busbar from contacting the metal sound insulation felt 22 and causing surface damage;

[0048] It also includes a connection limiting portion, which includes a connection groove 41 and a connection block 42; the connection groove 41 is opened in the middle of the inner side of the end block 23, and the upper and lower ends of the connection block 42 are fixedly connected to the connection groove 41;

[0049] The clamping connection between the upper and lower ends of the connecting block 42 and the connecting groove 41 further defines the structure of the end block 23, and the degree of the connecting block 42 extends out of the connecting groove 41, which can meet the splicing and installation of the structure between the connected anti-corona shields 21;

[0050] After the installation of the anti-corona cover 21 is limited in the above structure, the utility model uses external screws to install and fix the metal sound insulation felt 22 inside the anti-corona cover 21, and uses screws again to install the isolation ring 24 on the inner wall of the metal sound insulation felt 22. The screws used are extended to the inside of the metal sound insulation felt 22 and the isolation ring 24. At this time, multiple anti-corona covers 21 can be spliced ​​according to the use requirements, that is, the upper and lower ends of the connecting block 42 are clamped with the inner wall of the connecting groove 41 and extended into the connected connecting grooves 41;

[0051] While meeting the anti-corona protection for the busbar, the purpose of noise reduction can be achieved, and the surface damage during the installation of the busbar can be avoided. In addition, the assembly of multiple anti-corona covers 21 can be met, thereby improving the applicability and functionality of the structure.

[0052] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
