Technical Field
[0001] This application belongs to the field of cable construction technology, specifically relating to an insulation repair device. Background Technology
[0002] In the existing technology, outdoor overhead construction of insulated conductors is often required during the setting up of power systems. Outdoor overhead construction of insulated conductors refers to the overhead laying of conductors wrapped with insulating materials. It is a way to realize power transmission and distribution and is widely used in urban and rural power distribution networks, as well as power supply for industrial and commercial facilities.
[0003] In existing technologies, as the service life of insulated cables erected outdoors at high altitudes increases, there are sometimes cases of localized damage to the insulation or localized cracking of the cable surface. In order to avoid leakage, short circuits and other problems in the insulated cables, it is often necessary to apply for a power outage plan and arrange repairs in a timely manner. The entire repair cycle is long and will affect the power supply of the entire area. The cable repair efficiency is low. Therefore, there is an urgent need for a temporary cable repair device that can temporarily repair cables, thereby improving the safety factor of cables after aging, without affecting the power supply of the entire area. Utility Model Content
[0004] This application addresses the technical problem in the prior art where, as outdoor cables age, insulated cables erected at high altitudes exhibit localized aging. To prevent leakage and short circuits, repairs are required for these localized aging areas. However, prior repairs necessitate power outage plans, impacting the power supply to the entire area and reducing repair efficiency. This application proposes an insulation repair device capable of temporarily repairing locally damaged cables.
[0005] This application adopts the following scheme: an insulation repair device, including a lower housing, an upper housing disposed on the lower housing, a repair chamber disposed between the upper housing and the lower housing, and a clamping mechanism disposed between the upper housing and the lower housing. When the cable X to be repaired can be matched and extended into the repair chamber, the upper housing and the lower housing respectively cover the outer periphery of the cable X to be repaired, and the clamping mechanism is used to clamp the cable X to be repaired in the repair chamber.
[0006] In some possible embodiments, the system further includes a rotating shaft disposed on the lower housing and a rotating groove disposed on the upper housing at a position corresponding to the rotating shaft, wherein the upper housing can rotate about the rotating axis toward or away from the lower housing.
[0007] In some possible embodiments, the repair chamber includes a first repair groove on the lower housing and a second repair groove on the upper housing. When the upper housing is fitted onto the lower housing, the first repair groove and the second repair groove together form the repair chamber.
[0008] In some possible embodiments, the repair chamber further includes a first tooth on the inner surface of the first repair groove, which fits against the outer periphery of the cable X to be repaired when the upper housing is fitted onto the lower housing.
[0009] In some possible embodiments, the clamping mechanism includes an adjustment hole disposed on the upper housing and located above the repair chamber, a pressure rod matched to the adjustment hole, and a pressure block disposed on one end of the pressure rod near the repair chamber. The pressure rod can move along the height direction of the adjustment hole toward or away from the repair chamber to clamp the cable X to be repaired in the repair chamber.
[0010] In some possible embodiments, the clamping mechanism further includes a connecting assembly disposed between the pressure rod and the pressure block, wherein the pressure block is detachably disposed on the pressure rod via the connecting assembly.
[0011] In some possible embodiments, the connecting assembly includes a connecting groove on the pressure block and a connecting post on the pressure rod located at a position corresponding to the connecting groove, the connecting post being able to extend into the connecting groove so that the pressure block is detachably mounted on the pressure rod.
[0012] In some possible embodiments, the clamping mechanism further includes a second tooth on the inner surface of the pressure block, which fits against the outer periphery of the cable X to be repaired when the repair cable X is clamped in the repair chamber.
[0013] In some possible embodiments, a fastening assembly is also included, which, when the upper housing is fitted onto the lower housing, restricts the upper housing from rotating away from the lower housing, thereby securing the upper housing to the lower housing.
[0014] In some possible embodiments, the fastening assembly includes a fastening hole on the upper housing and a fastening member on the lower housing located at a position corresponding to the fastening hole, the fastening member being able to fit into the fastening hole to fix the upper housing to the lower housing.
