[0036] Reference Figure 1 and Figure 2 , an embodiment of the present application provides an integrated conductive ring current collector device, comprising:
[0037] The integral conductive ring 1; the outer ring surface of the integral conductive ring 1 is a complete ring surface;
[0038] Stainless steel bracket 2;
[0039] The conductive oil tank 3 is arranged at the upper end of the stainless steel bracket 2; a conductive base 31 is symmetrically arranged in the conductive oil tank 3, and the conductive base 31 matches the outer ring surface of the integral conductive ring 1, and the outer ring surface of the integral conductive ring 1 is partially located in the conductive oil tank 3 and placed on the conductive base 31;
[0040] The elastic soft connection 4 is arranged at the middle of the bottom end of the stainless steel bracket 2;
[0041] At least two suspension studs 5 are symmetrically arranged on both sides of the upper end of the stainless steel bracket 2 .
[0042] Specifically, the stainless steel bracket 2 provides support and fixation for the integral conductive ring 1 and other components. The stainless steel bracket 2 itself has good corrosion resistance, adapts to the use requirements in harsh environments, and ensures the long-term stability of the current collector. It can be understood that joints are also symmetrically arranged on both sides of the stainless steel bracket 2.
[0043] The conductive oil groove 3 is a self-lubricating conductive oil groove 3, which is used to fill the conductive medium, reduce the power loss caused by friction, and improve the conductive efficiency. The conductive base 31 in the conductive oil groove 3 is in contact with the outer ring surface of the integral conductive ring 1, which is used to conduct current and maintain a good contact state with the outer ring to ensure the stable flow of current.
[0044] The elastic flexible connection 4 is a retractable flexible connection. The elastic flexible connection 4 can adapt to possible small displacements or vibrations during the working process through its elastic characteristics and provide a stable electrical connection.
[0045] The integral conductive ring current collector is connected to the load current from the elastic flexible connection 4. The load current passes through the elastic flexible connection 4, the conductive oil groove 3, and the integral conductive ring 1 in sequence, and is introduced into the conductive roller locked by the integral conductive ring 1 to achieve the purpose of supplying power to the conductive roller.
[0046] In this embodiment, the outer ring surface of the integral conductive ring is a complete ring surface. When the outer ring surface contacts the conductive oil groove for conduction, the contact surface between the integral conductive ring and the conductive oil groove remains stable to achieve smooth and constant conduction. The complete outer ring surface has little friction resistance with the conductive base, and also little wear.
[0047] In one embodiment, if Figure 3 As shown, the integrated conductive ring 1 comprises:
[0048] A conductive outer ring 11, the inner ring of the conductive outer ring 11 is a first inclined surface 111, and a plurality of threaded holes are formed on the first inclined surface 111;
[0049] The conductive inner ring 12 has an outer ring formed of a second inclined surface 121, and the second inclined surface 121 matches the first inclined surface 111; a plurality of threaded through holes are provided between the second inclined surface 121 and the side surface of the conductive inner ring 12, and the threaded through holes are provided correspondingly to the threaded holes; the conductive inner ring 12 is divided into a first inner ring 122 and a second inner ring 123, and a compensation opening is formed between the first inner ring 122 and the second inner ring 123;
[0050] A plurality of bolts 13 are provided, and the bolts 13 pass through the threaded through holes and the threaded holes in sequence.
[0051] Specifically, during assembly, when the conductive outer ring 11 and the conductive inner ring 12 are fastened with the bolts 13, the conductive inner ring 12 slides along the inclined surface of the conductive outer ring 11, causing the inner ring of the conductive inner ring 12 and the conductive roller to fit tightly together. The opening between the first inner ring 122 and the second inner ring 123 of the conductive inner ring 12 serves as a compensating opening, and the opening shrinks during the fastening process, so that during assembly, while the conductive inner ring 12 holds the conductive roller tightly, the conductive inner ring 12 and the conductive outer ring 11 are tightly fitted, thereby achieving the purpose of positioning and fastening.
[0052] The integrated conductive ring 1 provided in this embodiment can make the inner ring and the outer ring of the entire integrated conductive ring 1 a full-circle structure. During operation, the sliding contact surface is constant, the sliding is stable, and the conductive current is constant.
[0053] In one embodiment, the integrated conductive ring current collector further comprises:
[0054] The bottom plate 6 is installed on both sides of the bottom of the stainless steel bracket 2;
[0055] The mounting base plate 6 is connected to the stainless steel bracket 2 via the insulating terminal 7 .
[0056] Specifically, insulating terminals 7 may be provided at four corners of the stainless steel bracket 2 .
[0057] In this embodiment, the stainless steel bracket 2 and the mounting base plate 6 are connected using an insulating terminal 7. While achieving fixed positioning, the mounting base plate 6 and the stainless steel bracket 2 are insulated, so that the device is insulated from external connecting parts to prevent leakage, thereby ensuring safety and achieving the purpose of saving electricity.
[0058] In one embodiment, the integrated conductive ring current collector further comprises:
[0059] The isolation plate 8 is connected to a side of the mounting base plate 6 away from the stainless steel bracket 2 .
[0060] The isolation plate 8 plays an electrical isolation role, preventing current from flowing into areas that should not be touched, thereby enhancing safety.
[0061] In one embodiment, each suspension stud 5 is sleeved with an adjusting compression spring 9 .
[0062] The integrated conductive ring collector can be adjusted up and down by adjusting the compression spring 9, so that when the integrated conductive ring collector moves upward due to wear of the integrated conductive ring 1 during use, the entire integrated conductive ring collector can still perform the conductive function.
[0063] In one embodiment, the elastic flexible connection 4 includes multiple layers of copper foils. The elastic flexible connection 4 can be formed by welding multiple layers of copper foils, so that the elastic flexible connection 4 has a certain bending flexibility while maintaining excellent conductivity.
[0064] In one embodiment, the middle part of the elastic flexible connection 4 is an arc-shaped structure, which can greatly increase the up and down adjustment range of the entire integrated conductive ring collector device, and can make the adjustment compression spring 9 able to achieve up and down adjustment of the integrated conductive ring collector device under a smaller force.
[0065] When the current passing through is large, a larger integrated conductive ring is required to transmit the larger current. However, when the volume of the integrated conductive ring increases, the weight of the entire integrated conductive ring collector will increase a lot, the requirements for adjusting the compression spring 9 will be relatively high, and other components in the device will also need to be enlarged.
[0066] In one embodiment, at least two integral conductive rings 1 are arranged in parallel.
[0067] By arranging at least two integral conductive rings 1 in parallel, the conductive area can be increased while the increase in overall weight is small.
[0068] It can be understood that when a number of integral conductive rings are arranged in parallel, the number of other components, such as joints, suspension studs, adjustment compression springs, etc., can be increased accordingly.
[0069] In one embodiment, the integral conductive ring 1 is also provided with an anti-splash shield 10. The design of the anti-splash shield 10 can prevent arcs, sparks or splashed liquids generated during the working process from causing damage to the surrounding environment and personnel.
[0070] In one embodiment, the splash protection cover 10 is a transparent cover. The transparent cover in this solution allows the user to observe the working state of the integrated conductive ring 1 in real time, thereby increasing visibility and safety.
[0071] The above are only specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
