Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electric power equipment, in particular to a wear-resistant and oxidation-resistant conductive rod. Background Art
[0002] The history of wear-resistant and anti-oxidation conductive rods can be traced back to the early 20th century, when the demand for conductive rods continued to increase due to the rapid development of the power industry. The original conductive rods were made of metal materials such as copper or steel, but due to long-term outdoor use, they were easily corroded and worn, resulting in a decrease in conductivity. With the development of science and technology, people began to study how to improve the wear resistance and oxidation resistance of conductive rods, so various new materials and surface treatment technologies emerged. Stainless steel has excellent corrosion resistance and wear resistance, and can maintain the conductivity of conductive rods for a long time. At the same time, stainless steel also has good processing performance and beautiful appearance, making the manufacture of conductive rods easier and more diverse. With the continuous development of science and technology, people have also developed various new surface treatment technologies, such as spraying wear-resistant coatings, plating, etc., to further improve the wear resistance and oxidation resistance of conductive rods. In addition, some new materials such as copper alloys and titanium alloys are gradually used in the manufacture of conductive rods, making the performance of conductive rods more excellent. At present, wear-resistant and anti-oxidation conductive rods have been widely used in power, communications, transportation, petrochemicals and other fields, and have become one of the important equipment to ensure the normal operation of equipment and systems. In the future, with the continuous development of new materials and new technologies, the performance of wear-resistant and oxidation-resistant conductive rods will be further improved, and their application areas will continue to expand.
[0003] The traditional conductive rods will have the following problems during use. Wear problem: During the long-term use of the conductive rod, the surface is prone to wear and scratches due to friction and contact. These wear and scratches will destroy the conductive performance of the conductive rod and affect its normal operation. For example, where the conductive rod contacts the external wires, the external wires often swing left and right under the action of wind. This left and right swing will cause frequent friction and contact between the wires and the conductive rods, thereby wearing the conductive rods. In addition, the conductive rods are prone to oxidation due to factors such as moisture, oxygen and chemicals in the environment, especially in humid environments. Oxidation will increase the contact resistance of the conductive rod, unstable current, and seriously affect the normal operation of the entire circuit. Therefore, the oxidation problem of the conductive rod needs to be dealt with in a timely manner. Utility Model Content
[0004] 1. Technical issues to be resolved
[0005] In view of the deficiencies in the prior art, the utility model provides a wear-resistant and oxidation-resistant conductive rod, which has the advantages of reducing the wear of the connection between the conductive rod and the external wire and preventing oxidation of the external conductive rod, and solves the problem that the conductive rod is prone to wear and scratches on the surface due to friction and contact during long-term use. These wear and scratches will destroy the conductive performance of the conductive rod and affect its normal operation. For example, where the conductive rod contacts the external wire, the external wire often swings left and right under the action of wind. This left and right swing will cause frequent friction and contact between the wire and the conductive rod, thereby wearing the conductive rod. In addition, the conductive rod is prone to oxidation due to factors such as moisture, oxygen and chemicals in the environment, especially in a humid environment. Oxidation will cause the contact resistance of the conductive rod to increase, the current to be unstable, and seriously affect the normal operation of the entire circuit.
[0006] (II) Technical solution
[0007] In order to achieve the above-mentioned purpose of reducing the wear of the connection between the conductive rod and the external wire and preventing the external oxidation of the conductive rod, the utility model provides the following technical solutions: a wear-resistant and oxidation-resistant conductive rod, comprising a guide rod, the guide rod is in the shape of a long cylindrical strip, a mounting strip is provided at the bottom of the guide rod, a nut is provided on the guide rod located at the lower part of the mounting strip, an anti-oxidation sleeve is provided on the outside of the guide rod, the anti-oxidation sleeve is in the shape of a hollow cylinder, the inner diameter of the anti-oxidation sleeve is larger than the outer diameter of the guide rod, retraction rings are provided on the two end faces of the anti-oxidation sleeve, the inner diameter of the retraction ring is smaller than the outer diameter of the anti-oxidation sleeve, there is a gap between the anti-oxidation sleeve and the guide rod, a sleeve opening is provided at the bottom of the anti-oxidation sleeve, and a sealing end cover capable of sealing the gap is provided on the sleeve opening.
[0008] Preferably, a fixing block is provided on the top of the guide rod.
[0009] Preferably, the anti-oxidation sleeve is arranged between the fixing block and the mounting strip.
[0010] Preferably, the top and bottom of the anti-oxidation sleeve are in contact with the bottom of the fixing block and the top of the mounting strip, respectively.
[0011] Preferably, a guide plate perpendicular to the top of the fixing block is provided on one side of the fixing block.
[0012] Preferably, the guide plate is provided with a threading hole, and an anti-wear ring is installed in the threading hole.
[0013] Preferably, the anti-wear ring is in the shape of a circular ring, and an arc chamfer is processed on the inner side of the anti-wear ring. The anti-wear ring can rotate in the threading hole.
[0014] (III) Beneficial effects
[0015] Compared with the prior art, the utility model provides a wear-resistant and oxidation-resistant conductive rod having the following
[0016] Beneficial effects:
[0017] 1. A wear-resistant and oxidation-resistant conductive rod is used by the cooperation of an anti-oxidation sleeve, a sleeve opening and a sealing end cover. After the anti-oxidation sleeve is mounted on the guide rod, there will be a gap between the anti-oxidation sleeve and the guide rod. In order to prevent the outer surface of the guide rod from being oxidized by the outside air, some anti-oxidation liquids can be loaded into the gap through the sleeve opening. Since both ends of the anti-oxidation sleeve are provided with retracted rings, the gap between the anti-oxidation sleeve and the guide rod can be completely sealed. In this way, when various anti-oxidation liquids are input into the gap, no leakage will occur. After the internal gap is completely filled, the sleeve opening is completely sealed through the sealing end cover. At this time, the outer surface of the guide rod is completely protected by the anti-oxidation liquid, which can reduce the oxidation of the guide rod surface by the outside air. Thereby, the effect of preventing the external oxidation of the conductive rod is achieved.
[0018] 2. A wear-resistant and anti-oxidation conductive rod is used in conjunction with a guide plate, a threading hole and an anti-wear ring. First, the anti-wear ring is assembled in the threading hole, and then the wire connected to the outside world is passed through the anti-wear ring to be connected and fixed. Due to the presence of various factors such as wind force in the outside world that cause the wire to shake or sway, when the wire shakes or sways, if there is no anti-wear ring, the wire will directly rub against the threading hole, which will wear and damage the guide plate at a very fast speed. However, after the anti-wear ring is installed, first, during the swinging of the wire, since the anti-wear ring can rotate in the threading hole, the force of the wire on the threading hole will be dispersed to a circular ring, and will not rub a certain place of the threading hole for a long time. In addition, the annular side of the inner side of the anti-wear ring is processed with an arc chamfer, which can further reduce the friction between the wire and the anti-wear ring, thereby reducing the wear on the wire. Thereby achieving the effect of reducing the wear at the connection between the conductive rod and the external wire. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0028] See also Figure 1-7 A wear-resistant and oxidation-resistant conductive rod comprises a guide rod 3, the guide rod 3 is in the shape of a long cylindrical strip, a mounting strip 1 is arranged at the bottom of the guide rod 3, a nut 4 is arranged on the guide rod 3 located below the mounting strip 1, when in use, the conductive rod can be fixed on the electrical box by the mounting strip 1 and the nut 4, and then connected to the external wire through the guide plate 6. The guide rod 3, as the core part of the conductive rod, is made of copper or stainless steel and other materials with excellent conductivity and corrosion resistance. The outer cover is covered with an anti-oxidation cover 2 to protect the guide rod 3 from moisture, oxygen and chemicals in the environment.
[0029] The outer sleeve of the guide rod 3 is covered with an anti-oxidation sleeve 2, which is a hollow cylindrical shape. The inner diameter of the anti-oxidation sleeve 2 is larger than the outer diameter of the guide rod 3. The two end faces of the anti-oxidation sleeve 2 are provided with retracted rings 22, and the inner diameter of the retracted ring 22 is smaller than the outer diameter of the anti-oxidation sleeve 2. There is a gap 9 between the anti-oxidation sleeve 2 and the guide rod 3. The anti-oxidation sleeve 2 is made of high temperature resistant, corrosion resistant, and insulating materials such as polytetrafluoroethylene. Its inner diameter is larger than the outer diameter of the guide rod 3, forming a gap 9. This gap 9 can be injected with anti-oxidation liquid to further enhance the anti-oxidation ability of the guide rod 3. The two end faces of the anti-oxidation sleeve 2 are provided with retracted rings 22, which can ensure that the gap 9 between the anti-oxidation sleeve 2 and the guide rod 3 is completely sealed to prevent liquid leakage. The bottom of the anti-oxidation sleeve 2 is provided with a sleeve opening 21, and the sleeve opening 21 is provided with a sealing end cover 8 that can seal the gap 9. A sleeve opening 21 is provided at the bottom of the anti-oxidation sleeve 2, which is convenient for injecting anti-oxidation liquid into the gap 9. The sealing end cover 8 can completely seal the sleeve opening 21 to ensure that the anti-oxidation liquid inside does not leak. The anti-oxidation sleeve 2 is arranged between the fixed block 5 and the mounting strip 1. The top and bottom of the anti-oxidation sleeve 2 are in contact with the bottom of the fixed block 5 and the top of the mounting strip 1, respectively. In this way, the anti-oxidation sleeve 2 is pressed between the two, which can prevent the anti-oxidation sleeve 2 from vibrating when external vibration occurs, thereby causing a gap 9 between the anti-oxidation sleeve 2 and the guide rod 3, and finally causing the internal anti-oxidation liquid to flow out and cause damage.
[0030] A fixing block 5 is provided at the top of the guide rod 3. A guide plate 6 perpendicular to the top of the fixing block 5 is provided on one side of the fixing block 5. A fixing block 5 is provided at the top of the guide rod 3 for fixing wires or other connecting objects. A guide plate 6 perpendicular to the top of the fixing block 5 is provided on one side of the fixing block 5, and a threading hole 10 is provided on the guide plate 6 for threading wires.
[0031] The guide plate 6 is provided with a threading hole 10, and an anti-wear ring 7 is installed in the threading hole 10. The anti-wear ring 7 is in a circular shape, and an arc chamfer 71 is processed on the inner side of the anti-wear ring 7. The anti-wear ring 7 can rotate in the threading hole 10. The anti-wear ring 7 installed in the threading hole 10 is made of wear-resistant material, such as ceramic or hard alloy. When the wire passes through the threading hole 10 and is swayed or shaken by external factors (such as wind force), the anti-wear ring 7 can rotate in the threading hole 10 to disperse the force of the wire on the threading hole 10, prevent the wire from directly rubbing against the threading hole 10, and thus reduce the wear of the wire.
[0032] Working principle: After the anti-oxidation sleeve 2 is assembled on the guide rod 3, there will be a gap 9 between the anti-oxidation sleeve 2 and the guide rod 3. In order to prevent the outer surface of the guide rod 3 from being oxidized by the external air, some anti-oxidation liquid can be loaded into the gap 9 through the sleeve 21. Since both ends of the anti-oxidation sleeve 2 are provided with retracted rings 22, the gap 9 between the anti-oxidation sleeve 2 and the guide rod 3 can be completely sealed. In this way, when various anti-oxidation liquids are input into the gap 9, no leakage will occur. After the internal gap 9 is completely filled, the sleeve 21 is completely sealed by the sealing end cover 8. At this time, the outer surface of the guide rod 3 is completely protected by the anti-oxidation liquid, which can reduce the oxidation of the surface of the guide rod 3 by the external air.
[0033] First, the anti-wear ring 7 is assembled in the threading hole 10, and then the wire connected to the outside world is passed through the anti-wear ring 7 to be connected and fixed. Due to the existence of various factors such as wind force in the outside world that cause the wire to shake or sway, when the wire shakes or sways, if there is no anti-wear ring 7, the wire will directly rub against the threading hole 10, which will wear and damage the guide plate 6 at a very fast speed. However, after the anti-wear ring 7 is installed, first, during the shaking process of the wire, since the anti-wear ring 7 can rotate in the threading hole 10, the force of the wire on the threading hole 10 will be dispersed to a circular ring, and will not rub a certain place of the threading hole 10 for a long time. In addition, the annular side of the inner side of the anti-wear ring 7 is processed with an arc chamfer 71, which can further reduce the friction between the wire and the anti-wear ring 7, thereby reducing the wear on the wire.
