The composite pipe is a novel composite pipe, and has good mechanical property and corrosion resistance, the weight is only 1/4 of that of a steel pipe, the service life can reach more than ten times of that of a metal continuous pipe, along with the development of an oil field exploitation technology, the using amount of the composite continuous pipe in an oil field is increased day by day, but the existing composite continuous pipe has the case that the pipeline leakage caused by external force damage occurs at any time, more serious damage can be found at the first time and can be repaired in time, but the leakage caused by slight damage is difficult to find in time, and then greater loss is caused, and the use limitation is higher.
Disclosure of Invention
In order to solve the technical problems, the invention provides the built-in optical fiber composite material continuous pipeline which can realize timely reminding and accurately position the position of a leakage point of a pipeline, is convenient for workers to find in time, avoids causing greater loss and reduces use limitation.
The invention relates to a composite material continuous pipeline with a built-in optical fiber, which comprises a composite material pipe, an optical fiber and a protective layer, wherein the optical fiber is wound in the outer wall of the circumference of the composite material pipe according to a spiral structure by taking the central axis of the composite material pipe as a reference, the winding angle of the optical fiber is 15-45 degrees, and the protective layer is sleeved on the outer wall of the circumference of the composite material pipe in a coating mode.
According to the continuous pipeline with the built-in optical fiber composite material, the protective layer is made of thermoplastic resin.
According to the built-in optical fiber composite material continuous pipeline, the optical fibers are embedded into the outer surface layer of the composite material pipe.
Compared with the prior art, the invention has the beneficial effects that: firstly when winding and setting up optic fibre, twine according to the bend radius of combined material tubular product, the winding angle needs to be between 15 ~ 45, then coat one deck protective layer on the circumference outer wall of combined material tubular product again, play good protection to optic fibre, when using, in case leak or seepage take place, optic fibre can experience the change and go out the signal transmission, terminal equipment receives this signal and the concrete position of analytic department leak source, thereby can realize in time reminding and pinpoint the leak source position of pipeline, the staff in time discovers of being convenient for, avoid causing bigger loss, reduce the use limitation.

Detailed Description
The following detailed description of embodiments of the present invention is provided in connection with the accompanying drawings and examples. The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.
As shown in fig. 1 to fig. 3, the built-in optical fiber composite continuous pipeline of the present invention comprises a composite pipe 1, an optical fiber 2 and a protective layer 3, wherein the optical fiber 2 is wound inside the outer circumferential wall of the composite pipe 1 according to a spiral structure with the central axis of the composite pipe 1 as a reference, the winding angle of the optical fiber 2 is 15 to 45 degrees, and the protective layer 3 is sleeved on the outer circumferential wall of the composite pipe 1 in a coating manner; firstly when the winding sets up optic fibre 2, twine according to the bend radius of combined material tubular product 1, the winding angle needs to be between 15 ~ 45, then coat one deck protective layer 3 on the circumference outer wall of combined material tubular product 1 again, play good protection to optic fibre 2, when using, in case take place to leak or the seepage, optic fibre 2 can experience the change and go out the signal transmission, terminal equipment receives this signal and the concrete position of analytic department leak source, thereby can realize in time reminding and the leak source position of accurate positioning pipeline, the staff in time of being convenient for discovers, avoid causing bigger loss, reduce the use limitation.
According to the continuous pipeline with the built-in optical fiber composite material, the protective layer 3 is made of thermoplastic resin; by adopting the thermoplastic resin, the heat-sensitive adhesive has the performances of softening by heating and hardening by cooling, has good environmental adaptability, can play a better role in protection, and improves the use reliability.
According to the built-in optical fiber composite material continuous pipeline, the optical fiber 2 is embedded into the outer surface layer of the composite material pipe 1; the optical fiber 2 is installed in an embedded winding mode, so that the optical fiber 2 is convenient and reliable to install, and the use reliability is improved.
When the built-in optical fiber composite continuous pipeline works, firstly, when an optical fiber 2 is wound, the optical fiber 2 is wound according to the bending radius of a composite pipe 1, the winding angle needs to be 15-45 degrees, then a protective layer 3 is coated on the circumferential outer wall of the composite pipe 1, the optical fiber 2 is well protected, once leakage or seepage occurs during use, the optical fiber 2 can sense the change and transmit a signal out, and a terminal device receives the signal and analyzes the specific position of a leakage point, so that the leakage point position of a pipeline can be timely reminded and accurately positioned.
According to the built-in optical fiber composite material continuous pipeline, the installation mode, the connection mode or the arrangement mode are common mechanical modes, and the built-in optical fiber composite material continuous pipeline can be implemented as long as the beneficial effects are achieved; the optical fiber of the built-in optical fiber composite material continuous pipeline is purchased from the market, and technicians in the industry only need to install and operate the optical fiber according to the attached use instruction.
