Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrical equipment technology, and in particular to a copper composite grounding busbar for ships. Background Art
[0002] The copper composite grounding busbar for ships is a type of grounding busbar, also called a grounding copper busbar. It is installed at the front end of the grounding wire from the ship's engine room to the grounding grid, and the grounding of all equipment in the engine room converges onto this busbar. In the ship's internal lightning protection system (or electrical system), the main function of the grounding busbar is voltage equalization. If there is too much equipment in the ship's engine room, an equalizing ring is usually made under the electrostatic floor. The equipment grounding wires and the electrostatic floor grounding wires are connected to the equalizing ring as close as possible. The purpose of this is to prevent ground potential backflash accidents. With equalized voltage and no potential difference between equipment, accidents can be avoided.
[0003] Currently, most existing grounding copper busbars adopt an integrated straight strip design. Since the length of this type of straight strip design is constant, it is difficult to make adaptive adjustments during the assembly and grounding application process. This is very unfavorable for use in the relatively small electrical equipment space inside ships, resulting in poor practicality and flexibility. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a copper composite grounding busbar for ships, which solves the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A copper composite grounding busbar for ships includes a composite copper base busbar. Limiting copper strips are welded and fixed to the front and back sides of the top surface of the composite copper base busbar. A first access through hole is longitudinally opened through the plate surface of the composite copper base busbar. A telescopic composite copper base busbar is slidably inserted into the top surface of the composite copper base busbar and the limiting copper strips. Limiting blocks are welded and fixed to the front and back sides of the top surface of the telescopic composite copper base busbar. A second access through hole is opened through the plate surface of the telescopic composite copper base busbar. Grounding bolts are mounted on the composite copper base busbar and the telescopic composite copper base busbar through the first and second access through holes. Assembly through holes are longitudinally opened on the opposite sides of the plates of the composite copper base busbar and the telescopic composite copper base busbar. Assembly bolt portions are installed inside the assembly through holes. Insulators are installed at the bottom of the composite copper base busbar and the telescopic composite copper base busbar through the assembly bolt portions. Mounting brackets are installed at the bottom of the insulators through the assembly bolt portions.
[0007] Preferably, the limiting copper buckle is a right-angled copper strip structure, and there are two limiting copper buckles, which are located on the top surface of the composite copper bottom strip near the left end.
[0008] Preferably, the number of limiting blocks is four, and the four limiting blocks are respectively located at the top corner of one side of the telescopic composite copper base busbar and near the top surface of the other side, and the limiting copper buckle is located between the four limiting blocks.
[0009] Preferably, the mounting bolt portion includes a mounting bolt body and an elastic washer, wherein the mounting bolt body is inserted inside the elastic washer.
[0010] Preferably, the insulator includes an insulating sleeve and a supporting internally threaded core tube, the insulating sleeve being fixedly fitted onto the outer surface of the supporting internally threaded core tube; the mounting bracket includes a support plate and mounting feet, the mounting feet being longitudinally through-holes located at the middle and both ends of the support plate.
[0011] Preferably, a height-balancing copper pad is welded and fixed to one end of the bottom surface of the telescopic composite copper base busbar near the assembly through hole. The center of the height-balancing copper pad is connected to the assembly through hole of the telescopic composite copper base busbar, and the bottom surface of the height-balancing copper pad is horizontal with the bottom surface of the composite copper base busbar.
[0012] Compared with the prior art, the beneficial effects of the present invention are:
[0013] This type of copper composite grounding busbar for ships consists of a split composite copper base busbar and a telescopic composite copper base busbar, forming the entire grounding copper busbar structure. Limiting copper buckles are used to constrain the sliding of the telescopic composite copper base busbar, and limiting blocks are used to prevent separation. This allows the composite copper base busbar and the telescopic composite copper base busbar to be adjusted in a telescopic manner. Once the first and second access through holes coincide, the entire composite copper busbar structure can be assembled and fixed for grounding. This provides a composite, telescopic copper busbar design, achieving the effect of easy adaptive adjustment during grounding application. It facilitates adaptive adjustment within the relatively confined space of electrical equipment on ships, greatly improving adaptability and flexibility, and possessing good practicality.

[0022] Reference Figure 1-5 A copper composite grounding busbar for ships includes a composite copper base busbar 1. Limiting copper buckles 2 are welded and fixed to the front and back sides of the top surface of the composite copper base busbar 1. A first access through hole 3 is longitudinally opened through the plate surface of the composite copper base busbar 1. A telescopic composite copper base busbar 4 is slidably inserted into the top surface of the composite copper base busbar 1 and the limiting copper buckles 2. Limiting blocks 5 are welded and fixed to the front and back sides of the top surface of the telescopic composite copper base busbar 4. A second access through hole 6 is opened through the plate surface of the telescopic composite copper base busbar 4. Grounding bolts 11 are mounted on the composite copper base busbar 1 and the telescopic composite copper base busbar 4 through the first access through hole 3 and the second access through hole 6. Assembly through holes 7 are longitudinally opened on the opposite sides of the plates of the composite copper base busbar 1 and the telescopic composite copper base busbar 4. Assembly bolt portions 8 are installed inside the assembly through holes 7. Insulators 9 are installed at the bottom of the composite copper base busbar 1 and the telescopic composite copper base busbar 4 through the assembly bolt portions 8. Mounting brackets 10 are installed at the bottom of the insulators 9 through the assembly bolt portions 8.
[0023] In this utility model, the limiting copper buckle 2 is a right-angled copper strip structure, and there are two limiting copper buckles 2. The two limiting copper buckles 2 are set on the top surface of the composite copper bottom row 1 near the left end.
[0024] More specifically, by setting two limiting copper buckles 2 on the top surface of the composite copper base bar 1 near the left end, the composite copper base bar 1 and the telescopic composite copper base bar 4 are prevented from separating, thus ensuring the convenience of assembly operations.
[0025] In this utility model, there are four limiting blocks 5, and the four limiting blocks 5 are respectively located at the top corner of one side of the telescopic composite copper base busbar 4 and near the top surface of the other side, and the limiting copper buckle 2 is located between the four limiting blocks 5.
[0026] More specifically, by setting the limiting copper buckle 2 between the four limiting blocks 5, the limiting copper buckle 2 is provided with a sufficient sliding range, while avoiding the structure from separating.
[0027] In this utility model, the assembly bolt part 8 includes an assembly bolt body 801 and an elastic washer 802, with the assembly bolt body 801 inserted inside the elastic washer 802.
[0028] More specifically, the assembly bolt body 801 is inserted inside the elastic washer 802 for structural assembly, which ensures the fastening effect, makes it less likely to loosen, and improves stability.
[0029] In this utility model, the insulator 9 includes an insulating sleeve 901 and a supporting internal thread core tube 902, with the insulating sleeve 901 fixedly sleeved on the outer surface of the supporting internal thread core tube 902; the mounting bracket 10 includes a bracket plate 1001 and mounting holes 1002, with the mounting holes 1002 longitudinally penetrating through the middle and both ends of the bracket plate 1001.
[0030] More specifically, the insulating sleeve 901 is fixedly sleeved on the outer surface of the supporting internal thread core tube 902, which ensures the stability of the connection inside the structure and avoids the instability of the connection in the polymer structure of the insulating material.
[0031] In this utility model, a height balancing copper pad is welded and fixed to one end of the bottom surface of the telescopic composite copper base busbar 4 near the assembly through hole 7. The center of the height balancing copper pad is connected to the assembly through hole 7 of the telescopic composite copper base busbar 4, and the bottom surface of the height balancing copper pad is horizontal to the bottom surface of the composite copper base busbar 1.
[0032] More specifically, by setting a height-balancing copper shim, the bottom surface of the height-balancing copper shim is made to be level with the bottom surface of the composite copper base plate 1, which facilitates assembly on both sides without changing the model of the insulator 9 and the mounting bolt part 8, reducing the inconvenience of adaptation.
[0033] Working principle: When adjusting the length of the entire composite copper busbar structure composed of the composite copper base busbar 1 and the telescopic composite copper base busbar 4, the telescopic composite copper base busbar 4 is pushed towards the composite copper base busbar 1 or pulled away from it. This causes the telescopic composite copper base busbar 4 to slide between the composite copper base busbar 1 and the limiting copper buckle 2. The limiting block 5 on the telescopic composite copper base busbar 4 provides a limit, which causes the composite copper base busbar 1 and the telescopic composite copper base busbar 4 to slide and contract or extend. When the first access through hole 3 and the second access through hole 6 are aligned, the grounding bolt 11 can be installed, thereby realizing the adjustment of the length of the entire composite copper busbar structure composed of the composite copper base busbar 1 and the telescopic composite copper base busbar 4.
