Description

Technical Field

[0001] The utility model relates to the technical field of jumper connection pipes, in particular to a jumper connection pipe for overhead power transmission lines. Background Art

[0002] Overhead power transmission lines are erected on the ground and are power lines insulated by insulators and air. An overhead line consists of parts such as conductors, overhead ground wires, insulator strings, poles, and grounding devices. Currently, there are mainly two types of connection tools for overhead power transmission line jumpers. One is a bolt parallel groove clamp, and the other is a hydraulic connection pipe.

[0003] When using a bolt parallel groove clamp, there are problems such as a small contact surface, a large contact resistance, and unreliable connection. When using a hydraulic connection pipe, due to the bulky hydraulic equipment, there are defects such as great difficulty in high-altitude hydraulic operation, long working hours, and inability to adapt to changes in the power grid operation mode. Therefore, a wiring device with a simple structure and convenient operation is needed.

[0004] A jumper connection pipe for overhead power transmission lines disclosed in the publication number CN213027208U. Although this jumper connection pipe for overhead power transmission lines includes a limit sleeve, a threaded hole, a compression bolt, an annular groove, a rotating ring, a ring body, a limit block, a compression rubber block, a fixed sleeve, a connecting screw, an adjusting rod, a positioning hole, an insertion rod, a movable sleeve, an adjusting bolt, and a stop block. The beneficial effect of this application is that the limit sleeve provides an installation position for the connecting line, and the distance between the two limit sleeves is adjustable, which is convenient for staff to operate. Specifically, through the movement between the adjusting rod and the movable sleeve, the relative position between the two is changed, realizing the change in the position between the two limit sleeves. After adjustment, by screwing the adjusting bolt into the positioning hole, the adjusted limit is achieved; among them, the structure for distance adjustment is installed on the rotating ring, and with the cooperation of the rotating ring and the annular groove, rotation adjustment can be performed, and the position can be changed, thus avoiding obstruction during the connection operation.

[0005] Although the above patent achieves the cooperation of the rotating ring and the annular groove, rotation adjustment can be performed, and the position can be changed, thus avoiding obstruction during the connection operation; however, when this connection pipe is in use, one adjusting rod cannot play a role in fixing the connection pipe, and it cannot effectively fasten the power transmission line, easily causing the connection pipe to slide and affecting the connection effect.

[0006] Therefore, it is very necessary to propose a jumper connection pipe for overhead power transmission lines to solve the above problems. Content of the Utility Model
