Description

[0001] The utility model relates to the technical field of drainage plate joints, in particular to a drainage plate joint for a power transmission line. Background Art

[0002] The drain plates commonly used in transmission lines on the market are directly connected and fixed to each other. Among them, the transmission line tension drain plate is an important part of the transmission line, which connects the conductor on one side with the conductor on the other side, and is a way to connect with the conductor. However, the transmission line has been running in the field for a long time. Due to the influence of environmental factors such as wind and earthquake, the bolts at the docking and fixing points of the existing transmission line drain plates often become loose, so that the two drain plates fixed by bolts have poor contact due to factors such as wind swing, which makes the poor contact of the drain plates easily cause the wire clamps to heat up, affecting the stable operation of the transmission line, and then causing the resistance of the drain plates to increase, which makes the conveying capacity of the drain plates decrease, and there are certain safety hazards, so manual maintenance and tightening at high altitudes are often required, which greatly increases the workload of electricians.

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.

[0025] like Figure 1-8As shown, the utility model provides a technical solution: a transmission line drainage plate joint, comprising a lower drainage docking plate 1 and an upper drainage docking plate 2, the right side of the lower drainage docking plate 1 is fixedly connected with a lower insulating lap plate 3, the left side of the upper drainage docking plate 2 is fixedly connected with an upper insulating lap plate 4, the bottom of the upper insulating lap plate 4 is in contact with the top of the lower insulating lap plate 3, through the setting of the upper insulating lap plate 4 and the lower insulating lap plate 3, the upper insulating lap plate 4 and the lower insulating lap plate 3 are independently set up and connected and installed, avoiding the occurrence of uneven conductivity caused by poor contact of bolts, the surfaces of the lower insulating lap plate 3 and the upper insulating lap plate 4 are penetrated by two docking screws 5, and the top of the docking screw 5 is fixedly connected with an octagonal nut 6, The surface of the octagonal nut cap 6 is sleeved with a clamping sleeve 7, and the inner wall of the clamping sleeve 7 is in extrusion contact with the surface of the octagonal nut cap 6. Through the arrangement of the octagonal nut cap 6 and the clamping sleeve 7, the rotation of the docking screw 5 is fixed to prevent the docking screw 5 from being loosened by the bolt fastening with the threaded cap barrel 10 due to rotation. The bottom of the clamping sleeve 7 is fixedly connected to the top of the upper insulating lap plate 4. The top of the octagonal nut cap 6 is fixedly connected with a protective cap 8. The top of the protective cap 8 is arranged in an arc shape. Through the arrangement of the protective cap 8, the effect of facilitating the upward removal of the docking screw 5 is achieved. The surface of the docking screw 5 is threadedly sleeved with a threaded cap barrel 10, and the top of the threaded cap barrel 10 is fixedly connected with a clamping toothed disc 11. The inner ring of the disk 11 is threadedly sleeved with the surface of the docking screw 5, and the surface of the clamping gear disk 11 is sleeved with an internally threaded clamping gear cylinder 9. The inner wall tooth groove of the internally threaded clamping gear cylinder 9 is meshed and sleeved with the surface of the clamping gear disk 11. The internally threaded clamping gear cylinder 9 is located in a groove opened at the bottom of the lower insulating lap plate 3. Through the arrangement of the internally threaded clamping gear cylinder 9 and the clamping gear disk 11, the sleeve engagement of the internally threaded clamping gear cylinder 9 and the clamping gear disk 11 is achieved, so that the threaded cap cylinder 10 cannot be threadedly displaced on the surface of the internally threaded clamping gear cylinder 9, thereby preventing the threaded fastening from loosening. The surface of the internally threaded clamping gear cylinder 9 runs through two side-turn pull rods 12, and the two side-turn pull rods 12 are symmetrically distributed in the middle of the internally threaded clamping gear cylinder 9. The surface of the side-turn pull rod 12 is symmetrical with the internally threaded clamping gear cylinder 9. The inner wall of the threaded tooth cylinder 9 is rotatably connected, and the bottom of the side rotation pull rod 12 is fixedly connected with a push-turn ball 13. Through the setting of the push-turn ball 13, it is convenient to drive the internal threaded tooth cylinder 9 to move internally to the lower insulating lap plate 3, so as to achieve the meshing sleeve separation of the internal threaded tooth cylinder 9 and the clamping tooth plate 11, thereby facilitating the disassembly of the bolt connection between the docking screw 5 and the internal threaded tooth cylinder 9. The two sides of the top of the side rotation pull rod 12 are fixedly connected with a clamping block 14. The inner wall of the lower insulating lap plate 3 is provided with a sliding groove for matching the clamping block 14. Through the setting of the clamping block 14, the rotation of the side rotation pull rod 12 is utilized to make the clamping block 14 clamped in the lower groove of the lower insulating lap plate 3, and then the side rotation pull rod 12 cannot be displaced upward.In order to ensure that the internal threaded gear cylinder 9 cannot be easily displaced into the lower insulating lap plate 3, two telescopic outer sleeves 15 are fixedly inserted into the inner wall of the lower insulating lap plate 3, and a sliding cylinder 16 is slidably inserted into the bottom of the telescopic outer sleeve 15. The bottom of the sliding cylinder 16 is fixedly connected to the top of the internal threaded gear cylinder 9, and a return spring 17 is sleeved on the surface of the sliding cylinder 16. The two ends of the return spring 17 are respectively fixedly connected to the inner wall of the lower insulating lap plate 3 and the top of the internal threaded gear cylinder 9. Through the arrangement of the telescopic outer sleeve 15, the sliding cylinder 16 and the return spring 17, the internal threaded gear cylinder 9 is provided with a rotation constraint and fixation effect, and the elastic force of the return spring 17 is cooperated, so that the internal threaded gear cylinder 9 is no longer pushed by an external force, and the meshing sleeve connection with the card tooth disk 11 is reset, and the lower drainage docking plate 1 and The surface of the upper drainage docking plate 2 is fixedly sleeved with a conductive sleeve 18, and the surface of the conductive sleeve 18 is fixedly connected with a U-shaped lap conductive plate 19. The bottom of the upper U-shaped lap conductive plate 19 is fixedly connected with two positioning heat-conducting heads 20. The bottom of the positioning heat-conducting head 20 is inserted into the through hole of the lower U-shaped lap conductive plate 19. The top of the internal threaded clamping cylinder 9 is slidably inserted with two pressure-resistant top limit cylinders 21. The top of the pressure-resistant top limit cylinder 21 is fixedly connected to the inner wall of the lower insulating lap plate 3. The end of the pressure-resistant top limit cylinder 21 located inside the internal threaded clamping cylinder 9 is fixedly connected with a uniform force support plate 22. Through the setting of the uniform force support plate 22 and the pressure-resistant top limit cylinder 21, the clamping toothed disk 11 is limited and supported, so as to ensure the upper insulating lap plate 4 and the lower insulating lap plate 3 are threadedly fastened and stabilized by the docking screw 5.

[0026] When in use, first, the lower drainage docking plate 1 and the upper drainage docking plate 2 are displaced and overlapped from top to bottom, so that the upper insulating overlap plate 4 and the lower insulating overlap plate 3 are overlapped, and the two U-shaped overlap conductive plates 19 at the bottom are overlapped with each other, and the positioning heat conducting head 20 is mutually clamped, and then the two docking screws 5 are placed from top to bottom into the clamping holes set between the upper insulating overlap plate 4 and the lower insulating overlap plate 3, and the octagonal nut 6 set on the top of the docking screw 5 is successfully inserted into the clamping sleeve 7, so that it is clamped. The connecting sleeve 7 is fixedly connected with the octagonal nut 6 through the notch provided in the inner ring, and then the threaded cap barrel 10 is rotated and tightened from the bottom thread of the docking screw 5, that is, the card-connecting toothed disc 11 is moved upward, and the pushing and turning ball 13 is rotated and pushed 90 degrees at the same time, thereby driving the internal threaded card-connecting toothed disc 9 to move inside the lower insulating lap plate 3. When the threaded cap barrel 10 drives the card-connecting toothed disc 11 to rotate to the extrusion contact with the uniform force supporting pressure plate, the force of the pushing and turning ball 13 is released. At this time, due to the elasticity of the reset spring 17 The force of the internal threaded gear cylinder 9 is driven to reset downward, so that the internal threaded gear cylinder 9 is sleeved and meshed with the card tooth plate 11, and then the pushing and turning ball 13 is rotated in the opposite direction to the original position. At this time, the bolt fastening of the docking screw 5 and the threaded cap cylinder 10 is completely fixed, and the bolts of the docking screw 5 and the threaded cap cylinder 10 cannot be loosened due to factors such as wind swing, so that the two U-shaped overlapping conductive plates 19 are always in a stable overlapping state. When the overlap between the two needs to be disassembled, the pushing and turning ball 13 is rotated and released by 90 degrees, and pushed upward to make the inner The threaded tooth barrel 9 is engaged and separated from the engaging tooth plate 11, and then the threaded cap barrel 10 is rotated to loosen the threaded connection of the threaded cap barrel 10 and the docking screw 5, and then the docking screw 5 can be taken out upward, and the upper insulating lap plate 4 can be lifted upward to separate the positioning thermal head 20 on the U-shaped lap conductive plate 19 above it from the slot hole of the U-shaped lap conductive plate 19 below, and the disassembly is completed by pulling them apart to the left and right. At the same time, the contents not described in detail in this manual belong to the existing technology known to professional and technical personnel in this field.
