Description

A cable self-detaching device used in communication overhead lines

technical field

The utility model relates to the construction field of communication overhead lines, in particular to a protective device for overhead lines.

Background technique

With the upgrading and transformation of my country's communication network, the construction of my country's communication infrastructure has been accelerated. However, in areas where natural disasters frequently occur in our country, especially in places where natural disasters such as earthquakes, mudslides, and floods frequently occur, communication accidents continue to occur, such as the poles of communication overhead lines are broken, the poles are tilted or washed away, etc., resulting in communication failures. The cable is partially or completely disconnected. These accidents not only cause losses to communication users and communication property units, but also lead to difficulties in reconstruction and maintenance of communication transmission networks after disasters.

In order to reduce the incidence of communication accidents and prevent the occurrence of such accidents, as shown in Figure 1, at present, the building scheme of pier (stone masonry or plain concrete) 002 is usually used to reinforce the overhead pole road at the point where disasters may occur or frequent disasters The pole base is used to protect the overhead line pole 001. Usually the pier 002 is cylindrical, and the overhead line pole 001 is fixed in the middle of the pier 002 .

Although this kind of solution is relatively low in cost, simple in construction, and can strengthen the pole foundation of the overhead pole road to a certain extent, it has weak impact force, limited load-bearing and pressure-bearing capacity, and can be used in strong natural disasters (earthquake, debris flow, etc.) , floods, etc.) are easy to sway, collapse, and be washed away when they arrive, and cannot prevent and effectively protect the safety of communication overhead lines to the greatest extent.

For example, patent application 201611045710.1 discloses a bridge pier protection structure and its construction method. The pier protective structure includes a pier body and a pier protective layer; connecting bolts are arranged on the inner sidewall of the pier protective layer; the pier protective layer is fixedly arranged on the outer sidewall of the pier body through the connecting bolts; the connecting bolts are embedded in the body of the pier. The protective cover of the pier protective structure described in the utility model is wrapped on the outside of the pier, and the high anti-seepage performance of the protective cover can be used to completely isolate the contact between water and the concrete pier, thereby inhibiting the corrosion of the internal steel bars and concrete, effectively The bridge pier is protected and the service life is prolonged.

However, this patent application still uses a cylindrical abutment, which has the disadvantages of weak impact force and limited bearing and compression capacity. At the same time, since the pole is fixed in the pier, in the event of a natural disaster, the cables in the communication overhead line are constrained by the pole, lacking enough elastic expansion space, and it is easy to be destroyed under the action of external impact Electric poles, broken cables, resulting in failure of communication lines. Although the pier solution can protect the overhead line to a certain extent by strengthening the pole foundation of the overhead pole road, in addition to its weak impact force, limited bearing and pressure capacity, it will also be affected by the region, geographical environment, and geological conditions. Due to the limitation or influence of factors such as climate conditions and changes, it cannot be effectively implemented or applied in some natural disasters or frequent disasters. Therefore, it is impossible to protect the safety of cables in communication overhead lines in a multi-plan and effective manner. .
