[0014] The principles and features of this utility model are described below with reference to the accompanying drawings. The embodiments described are for illustrative purposes only and are not intended to limit the scope of this utility model. The utility model is described more specifically in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of this utility model will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.

[0015] It should be noted that when a component is described as "fixed to" another component, it can be directly on the other component or may have a component in between. When a component is considered "connected to" another component, it can be directly connected to the other component or may have a component in between. When a component is considered "set on" another component, it can be directly set on the other component or may have a component in between. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0016] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0018] like Figures 1 to 2 As shown, a water pipeline suitable for complex terrain conditions includes a pipeline body 1, a connecting flange 2, a first mounting groove 3, a second mounting groove 4, a deformation detection optical fiber 5, a heat tracing cable 6, a sealing ring 7, a binding ring 8, and a connecting hole 9.

[0019] The pipe body 1 has connecting flanges 2 at both ends. The connecting flanges 2 of two adjacent pipe bodies 1 are fixedly connected by bolts. The connecting flanges 2 have several connecting holes 9, which are fixed by bolts.

[0020] The inner ring of the end face of the connecting flange 2 is provided with an annular groove and a sealing ring 7 is installed in the annular groove, which can make the connection of the two pipe bodies 1 more airtight and reduce the probability of leakage.

[0021] The side wall of the pipe body 1 is provided with several first mounting grooves 3 and second mounting grooves 4. The first mounting grooves 3 and second mounting grooves 4 are both connected to the connecting flange 2 at the end face of the pipe body 1. A deformation detection optical fiber 5 is installed in the first mounting groove 3, and a heat tracing cable 6 is installed in the second mounting groove 4. The deformation detection optical fiber 5 is connected to an external controller, and the heat tracing cable 6 is connected to an external power supply.

[0022] The deformation detection fiber 5 is in contact with the pipe body 1. All three deformation detection fibers 5 are connected to the controller through jumpers and BOTDA demodulator. By collecting and analyzing strain data, the strain change of the pipe body 1 is determined, and the deformation monitoring of the pipe body 1 is realized.

[0023] The heat tracing cable 6 can be heated as needed, and can be heated in cold weather to reduce the damage of freezing to the pipe body 1.

[0024] The deformation detection fiber optic cable 5 and the heating cable 6 can be fixed in various ways, for example:

[0025] The deformation detection fiber 5 is bonded to the first mounting groove 3.

[0026] The heat tracing cable 6 is bonded to the second mounting groove 4.

[0027] Several binding rings 8 are arranged at intervals along the length of the pipe body 1. The binding rings 8 can bind the deformation detection optical fiber 5 and the heat tracing cable 6 to prevent them from detaching from the pipe body 1.

[0028] This invention can monitor pipeline deformation, prevent freezing disasters, can be applied in complex terrain, and can extend the service life of pipelines.

[0029] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any improvements made using the inventive concept and technical solution of the present invention, or direct application to other situations without modification, are all within the protection scope of the present invention.
