Description

A New Detachable Seven-Hole Honeycomb Tube

technical field

The invention belongs to communication auxiliary equipment and relates to a novel detachable seven-hole honeycomb pipe.

Background technique

Due to external factors or the optical fiber itself, etc., the optical cable line failure will occur. The service interruption caused by the failure of the optical cable line is long and affects a wide range of business areas, which is the key link in the security work. In order to make the optical cable communication system work normally, in addition to careful design, careful construction, and normal maintenance, once an optical cable failure occurs, it must be repaired in time to ensure the smooth flow of the line and shorten the failure time as much as possible.

The seven-hole honeycomb tube is a kind of communication pipe that protects the optical cable outside the optical cable. The current seven-hole honeycomb tube is a honeycomb plastic tube composed of seven hexagonal holes. The cross-sectional shape is like a honeycomb. It adopts an integrated porous honeycomb and reasonable mechanical structure, which is convenient for the conduction, isolation and protection of optical cables. The compression resistance of the pipe is 10-100 times higher than that of ordinary plastic pipes. However, since the current seven-hole honeycomb tube cannot be disassembled and replaced with a new one, after the cable repair is completed, the cable is often buried directly or a communication well is repaired at the repair point for follow-up treatment, which is very costly. If it is directly buried, the outer layer of this section of optical cable will not be protected after being buried, and it will easily fail again; To protect the outer layer of the honeycomb pipe, all optical cables on the honeycomb pipe need to be cut over, which will cause large-scale service interruption and affect communication quality. After the direct landfill, there is generally no secondary excavation. If this section of optical cable has problems again, it cannot be used. Only a new section of optical cable can be built, which will increase the cost. Similarly, the way of laying wells at the emergency repair point will also increase the emergency repair cost.

Contents of the invention

The purpose of the present invention is to solve the above problems and provide a new detachable seven-hole honeycomb tube, which has simple structure, low cost, overall stability and pressure resistance, and can accommodate the same number of optical cables. At the same time, the sub-tube can be disassembled A new detachable seven-hole honeycomb tube with features such as replacement.

The purpose of the present invention is achieved like this: a novel detachable seven-hole honeycomb tube, including sub-tube, opening, cover plate, and joint bag; seven hexagonal sub-tubes are stacked together to form a honeycomb, each outside It is fixed by a joint package at a certain distance. The joint package is a hollow cylinder with the same internal shape as the sub-tubes stacked together; there is an opening on one side of the hexagonal sub-tube, and the opening is sealed with a matching cover; the joint The bag consists of two parts that snap together with a push-pull.

detailed description

As shown in Figure 1, Figure 2, Figure 3, Figure 4, Figure 5, Figure 6, Figure 7 and Figure 8, a new detachable seven-hole honeycomb tube, including sub-tubes, openings, cover plates, and joint packs .

Seven hexagonal sub-tubes 1 are stacked together to form a honeycomb, and the outside is fixed by a joint package 2 at a certain distance.

The sub-tube 1 has two kinds: one is a hollow hexagonal prism; the other sub-tube 1 is provided with an opening 3 on one side of the tube wall to facilitate the insertion of the optical cable, and the opening 3 is sealed with the supporting cover plate 4,5 after the optical cable is put in.

Different geometries can be used for the cover plates 4,5.

There are two types of joint packs 2: one is a hollow cylinder, the inner shape 6 is the same as the stacked sub-tubes 1, which is convenient to clamp and fix the sub-tubes 1; It is composed of two parts and can be used for the service optical cable carried in the original pipe hole.

After the cable duct is damaged, if there is no optical cable carrying services in the tube hole, use the hollow hexagonal prism sub-tube 1 for emergency repair; if there is an optical cable carrying services in the tube hole, use the sub-tube 1 with opening 3 for emergency repair After the optical cable is restored, it is put into the sub-tube 1 from the opening 3, and the corresponding matching cover plates 4, 5 are fastened, and the emergency repair is completed.

The overall new pipeline is fixed with a hollow cylindrical joint package 2; when the pipeline needs to be repaired, it is fixed with a push-pull snap-fit joint package 2 after the emergency repair is completed.

The beneficial effects of the present invention are: after use, if a certain sub-pipe 1 is damaged, it can be pulled out separately for replacement; since it can be replaced in time, it can be used repeatedly and permanently; the cost can be completely saved by one-time repair, and secondary excavation can be avoided cost; improved repair efficiency; and does not affect the business optical cables carried in other tube holes; this new type of pipeline can be used in all new pipelines, and since the performance such as compression resistance has not changed, there is no need to change the construction requirements; the old When the seven-hole honeycomb pipe is damaged, a new seven-hole honeycomb pipe can be used for replacement repair.

The invention is applicable to various pipelines in the field of communication, electric power and other optical cables and cable engineering fields. The sub-pipe 1 can be disassembled arbitrarily, which is convenient for replacement.
