However, there is still a problem that the service life of the pipelines is greatly reduced due to long-term exposure to the wilderness, resulting in long-term erosion by wind and sand.

[0023] The present invention is further described in detail below with reference to the embodiments:

[0024] Example 1

[0025] like Figure 1-5 As shown, the utility model provides a long-distance natural gas pipeline protection device, including a pipeline 3, a fixing mechanism 1 is provided on the outer surface of the pipeline 3, and a protective mechanism 2 is provided on the outer surface of the fixing mechanism 1. The fixing mechanism 1 includes a clamping device 16, and the clamping device 16 is movably connected to one end of the outer surface of the pipeline 3. There are three clamping devices 16, and the three clamping devices 16 are evenly distributed on one end of the outer surface of the pipeline 3. The outer surface of the clamping device 16 is threadedly connected to an arc plate 11, and the side of the arc plate 11 is fixedly connected to a clamping plate 12, and the bottom surface of the clamping plate 12 is movably connected to a fixing bolt 13, and the other side of the arc plate 11 is fixedly connected to a connecting plate 14, and the connecting plate 14 is movably connected to the inside of the clamping plate 12. One end of the fixing bolt 13 is movably connected and passes through the bottom surface of the connecting plate 14, and the back of the arc plate 11 is fixedly connected to an extension plate 15.

[0026] In this embodiment, by combining the three fixing mechanisms 1 together, a complete circle can be formed. When the pipeline is disassembled, the device can be directly installed on the pipeline, and the three fixing mechanisms 1 can be connected together more stably through the cooperation of the clamping plate 12 and the connecting plate 14. The connected fixing mechanisms 1 are locked by the fixing bolts 13, and the protective mechanism 2 can be conveniently connected through the extension plate 15.

[0027] Example 2

[0028] like Figure 1-5As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the clamping device 16 includes a push plate 165, which is movably connected to the outer surface of the pipe 3, and a hollow groove 166 is provided inside the side of the push plate 165. The top surface of the push plate 165 is fixedly connected to the limiting buckle 164, and the internal rotation of the limiting buckle 164 is connected to the rotating plate 163. The top surface of the rotating plate 163 is fixedly connected to the threaded rod 161, the arc plate 11 is threadedly connected to the outer surface of the threaded rod 161, and the top surface of the threaded rod 161 is fixedly connected to the handle 162.

[0029] In this embodiment, the threaded rod 161 can be easily rotated through the handle 162. The threaded rod 161 is threadedly connected to the inside of the arc plate 11, so that when the threaded rod 161 is rotated, the position of the push plate 165 on its bottom surface can be driven to change, and due to the presence of the limit buckle 164 and the rotating plate 163, the push plate 165 can freely rotate and adjust the direction. The push plate 165 is pushed by the threaded rod 161 and is tightly attached to the surface of the pipe 3. At this time, due to the presence of the hollow groove 166, the bottom surface of the push plate 165 is slightly deformed, so that the device can better fit the shape of the pipe, thereby achieving a better fixing effect.

[0030] Example 3

[0031] like Figure 1-5 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the protective mechanism 2 includes a skeleton device 21, the skeleton device 21 is movably connected to the inside of the fixing mechanism 1, the outer surface of the skeleton device 21 is movably connected to the protective plate 22, and the side of the protective plate 22 is provided with a weight-reducing groove 23, the skeleton device 21 includes a fixing plate 211, the fixing plate 211 is tightly attached to the bottom surface of the extension plate 15, the side of the fixing plate 211 is fixedly connected with a connecting bolt 212, the connecting bolt 212 is movably connected and passes through the top surface of the extension plate 15, the side of the fixing plate 211 is fixedly connected with a lightweight connecting rod 213, the side of the lightweight connecting rod 213 is fixedly connected with a mounting bolt 214, the protective plate 22 is movably connected to the outer surface of the mounting bolt 214, the side of the lightweight connecting rod 213 is fixedly connected with a buckle 215, and the inside of the buckle 215 is clamped with a reinforcing rod 216.

[0032] In this embodiment, the protective mechanism 2 can be installed inside the fixing mechanism 1 through the cooperation of the fixing plate 211 and the connecting bolts 212, and due to the cooperation of the buckle 215 on the top surface of the lightweight connecting rod 213 and the reinforcement rod 216, the overall strength of the protective mechanism 2 is improved. The protective plate 22 is covered on the outer surface of the lightweight connecting rod 213 and fixed by the installation bolts 214, which can protect the pipeline 3. If a protective plate 22 is damaged, it can be removed and replaced separately.

[0033] The following is a detailed description of the working principle of the natural gas long-distance pipeline protection device.

[0034] like Figure 1-5 As shown, by sleeve-fitting the three fixing mechanisms 1 of the two groups on the left and right end surfaces of the pipe 3 to form a complete circle, and fixing the three together through the cooperation of the clamping plate 12, the connecting plate 14 and the fixing bolt 13, the handles 162 of the three directions are rotated to drive the threaded rod 161 to rotate inside the arc plate 11, so that the position of the push plate 165 on the bottom surface is changed, and the three push plates 165 support the pipe 3, so that a certain gap can be reserved between the device and the pipe 3, thereby enhancing the protection effect of the pipe 3. The push plate 165 is pushed by the threaded rod 161 and is tightly attached to the surface of the pipe 3. At this time, due to the presence of the hollow groove 166, the bottom of the push plate 165 is The surface of the device undergoes slight deformation, so that the device can better fit the shape of the pipeline and achieve better fixing effect. The connecting bolts 212 on the side of the fixing plate 211 are aligned with the holes of the extension plate 15 to fix the fixing plate 211. After fixing the two ends of the three fixing plates 211, the three reinforcing rods 216 are clamped into the inside of the buckle 215 to improve the strength of the device. The protective plate 22 is covered on the outer surface of the lightweight connecting rod 213 and fixed by the installation bolts 214, which can protect the pipeline 3. If a protective plate 22 is damaged, it can be removed and replaced separately. The device can effectively reduce the wear and erosion of the pipeline and improve the service life of the pipeline.

[0035] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
