Background technique

In the field of intelligent pipelines, the realization of intelligent pipelines mainly depends on the integration and compounding of functional cables or optical cables. At present, the existing composite technology mainly uses the following three methods: 1. Realize the composite of cables and pipes through specific fixtures, 2. Rely on physical modes such as cutters to groove the pipe and then composite with the pipe. 3. Directly compound the cable inside the pipe during the production process.

However, there are obvious defects in these forms: the first form cannot guarantee the stable connection between the functional cables and the pipe, and is arranged at the outer end of the pipe. The pipe itself cannot provide protection for these cables, and is prone to failure and damage. Data accuracy is not high. The second form fixes the cable in the pipe by slotting. The cutting of the tool requires high process control, which is easy to damage the pipe, and only specific slots can be cut, and only parallel slots can be cut. Winding process cannot be realized. The third type of composite intelligent pipeline is very difficult to connect the joints of this kind of composite pipe because the cables and pipes are already highly composited, especially because there are many cable joints placed inside the pipe, which makes the connection difficult and expensive, especially for some optical fiber cables. Cable connection is expensive and cannot be popularized.
