The device has a simple structure and low manufacturing cost. It changes the traditional fixed connection method between the suspension string and the crossarm into a movable connection method, so that it can quickly and effectively release the unbalanced tension generated by the conductor and the ground wire during operation, and can effectively ensure that the conductor and the ground wire will not be damaged during long-term operation, which can effectively ensure the safe operation of overhead power lines and the normal production and living electricity use of the majority of residents.

[0060] In order to effectively reduce the impact force when the roller contacts the groove block, the outer edge surface of the roller 2-6 is made of damping material, and the outer edge surface of the groove block 3 that contacts and cooperates with the roller 2-6 is made of damping material to effectively reduce the impact force when the roller contacts the groove block.

[0061] In order to enable the lower part of the vertical hanging plate to clamp the end of the transverse connecting section more stably, the outer contour of the vertical hanging plate 6-1 is convex, so that the lower part of the vertical hanging plate 6-1 can clamp the end of the transverse connecting section 7-1 more stably.

[0062] In order to avoid interference during use, the lower end of the vertical ear plate 2-2 is an arc structure, and the upper end of the sliding connection block 2-1 is an arc structure.

[0063] In order to make the release device more stable, it also includes two long screws, which are respectively inserted into two pairs of connecting holes 5 6-7 on the same side of the two kite-shaped connecting plates 6, and each long screw is connected to a locking nut on the outer side of the kite-shaped connecting plate 6 through threaded cooperation.

[0064] In this technical solution, the open end of the UB hanging plate is sleeved on the outside of the single ear end of the ZBD hanging plate, and the UB hanging plate and the ZBD hanging plate are movably connected by connecting bolt 2, so that the middle part of the hanging plate connection assembly can have a certain range of movement in the direction perpendicular to the cross arm, which is conducive to the release process of tension. The closed end of the UB hanging plate is used as the upper connection end of the hanging plate connection assembly, and the upper connection ends of the two hanging plate connection assemblies located at the end are respectively inserted into the U-shaped receiving grooves on the two kite-shaped connecting plates, and the upper connection ends of the hanging plate connection assembly are movably connected to the kite-shaped connecting plate by connecting bolt 3. At the same time, the upper connection end of the hanging plate connection assembly located in the middle is inserted into the U-shaped groove of the tower cross arm, and the hanging plate connection assembly is movably connected to the transverse connecting section by connecting bolt 4. In this way, the three hanging plate connection assemblies can have a certain range of movement in the length direction of the cross arm, which is further conducive to the release process of tension. The double ear ends of the ZBD hanging plate are used as the lower connecting ends of the connecting assembly, and the lower connecting ends of the three hanging plate connecting assemblies are all sleeved on the outside of the upper vertical section of the upper end of the mountain-shaped handle beam guide rail, and the lower connecting ends of the three hanging plate connecting assemblies are movably connected with the upper vertical section through the connecting bolt 5, so that the lower connecting ends of the three hanging plate connecting assemblies and the upper vertical section of the upper end of the mountain-shaped handle beam guide rail can have a certain range of movement in the cross arm length direction, which is further conducive to the release process of tension. In the mountain-shaped handle beam guide rail, the handle beam section is vertically fixedly connected to the middle part of the horizontal section, and two short protection sections are vertically fixedly connected at both ends of the horizontal section, so that a pair of symmetrical guide rails can be formed in the area between the handle beam section and the two short protection sections. A convex-shaped sliding groove is opened on the upper part of the sliding connection block in the ball rack type pulley connecting plate, and the convex-shaped sliding groove can be sleeved on the lower part of the mountain-shaped handle beam guide rail, so that the top of the ball rack type pulley connecting plate can be slidably assembled on the lower part of the mountain-shaped handle beam guide rail. By using a pair of fixed shafts to relatively assemble a pair of rollers in the strip opening of the convex-shaped slide groove, the ball-cage pulley connecting plate can be rolled with a pair of guide rails on the mountain-shaped handle guide rail through a pair of rollers, thereby effectively reducing the resistance during the sliding cooperation between the two, which is conducive to better release of tension. Two groove-shaped blocks are installed at both ends of the lower vertical section of the mountain-shaped handle guide rail, which can limit and block the two ends of the pair of guide rails, thereby effectively preventing the ball-cage pulley connecting plate from sliding out of the mountain-shaped handle guide rail. The connecting hanging plate on the suspension string is movably connected to the vertical ear plate on the ball-cage pulley connecting plate through the connecting bolt seven, so that the suspension string and the ball-cage pulley connecting plate have a certain rotation range, which is further conducive to the release process of tension. The device has a simple structure and low manufacturing cost. It changes the traditional fixed connection method between the suspension string and the crossarm into a movable connection method, so that it can quickly and effectively release the unbalanced tension generated by the conductor and the ground wire during operation, and can effectively ensure that the conductor and the ground wire will not be damaged during long-term operation, which can effectively ensure the safe operation of overhead power lines and the normal production and living electricity use of the majority of residents.
