Description

Technical Field

[0001] The invention belongs to the field of electric wire interval adjustment and maintenance devices, and in particular relates to an adjustable substation line interval maintenance device. Background Art

[0002] In power transmission and transformation lines, the distance between the lines depends on the distance between the insulator lines on the poles and towers. However, sometimes the wind will cause the wires to swing. Especially in coastal areas or mountainous areas, once a strong wind blows, the wires installed on the poles will swing randomly. In this case, there is a risk of short circuit between the wires. In order to prevent the short circuit between the wires, it is necessary to set up a device that can maintain the spacing between the wires. The spacer is a representative type of interval maintenance device. It is a simple device that relies on mechanical connection to create a gap. The two ends to be separated by the fixing devices at both ends are fixed, and the non-deformable support rods are used to create the desired spacing distance to achieve the maintenance of the interval. However, in order to separate the wires of each transmission line, the existing spacer has a larger shape of the entire spacer. The spacer of this structure is not easy to carry, especially for the work of setting the spacer on the high-altitude transmission line. It is extremely inconvenient for the staff to carry the larger spacer onto the pole or transmission line tower.

[0003] Patent document announcement number: CN109494668B discloses a wire spacer, including a support block, a connecting rod, a clamping joint and a clamping sleeve; the number of connecting rods is multiple, which are respectively arranged on the outer side of the support block and are all hinged with the support block; the clamping joint is arranged at one end of the connecting rod away from the support block, and the clamping sleeve is arranged on the outer side of the support block, and is arranged opposite to each connecting rod. The wire spacer provided by the present invention can be rotated by the staff towards the outer side of the support block and attached to the outer side of the support block, and each connecting rod and the clamping joint are fixed to the support block using a clamping sleeve. When in use, the clamping sleeve is moved to disengage from each connecting rod and the clamping joint, and then each connecting rod is rotated to a position perpendicular to the support block, so that the clamping joint is connected to the wire to achieve the purpose of separating each wire. This structure reduces the volume of the entire wire spacer, which is convenient for the staff to carry the wire spacer to climb to the high-altitude wire. However, the connecting rod of this spacer cannot be adjusted in length, and the clamping joint cannot be rotated 360° freely, so it is still inconvenient for the operator to install it, and the installation efficiency is low.

The reinforcing rib 3 includes a first rib 25 and a second rib 26, and the first rib 25 and the second rib 26 have the same specifications. The first rib 25 and the second rib 26 are vertically fixedly connected to each other, and both ends of the first rib 25 and the second rib 26 are fixedly connected to the inner wall of the ring body 1. There are six arms 2, and the six arms 2 are arranged at equal intervals around the outer circumference of the ring body 1. The arms 2 can rotate freely between parallel and perpendicular to the virtual center axis of the ring body 1. When in use, the arm 2 is rotated to a position perpendicular to the virtual center axis of the ring body 1. When the operator climbs the transmission line with the interval maintaining device, the arm 2 is rotated to a position parallel to the virtual center axis of the ring body 1, which is easy to carry.

[0043] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
