[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0023] See also Figure 1-Figure 6 The present invention provides a technical solution: a buried gas pipeline stress monitoring system, comprising a support platform 1, a protective shell 2 is fixedly connected to the top of the support platform 1, a mounting groove 3 is provided on the inner side of the protective shell 2, a strain gauge sensor 4 is arranged inside the mounting groove 3, a gas pipeline body 17 is fitted on the inner side of the strain gauge sensor 4, a side cover 5 is provided on the outer side of the protective shell 2, a first connecting plate 12 is fixedly connected to one side of the side cover 5, and a second connecting plate 13 is fixedly connected to the other side of the side cover 5; a support seat 7 is fixedly connected to the top of the support platform 1, a first protective box 8 is fixedly connected to the top of the support seat 7, an electric push rod 9 is fixedly installed inside the first protective box 8, an output shaft 10 is arranged inside the electric push rod 9, a connecting piece 11 is provided at one end of the output shaft 10, and the output shaft 10 is fixedly connected to the first connecting plate 12 through the connecting piece 11; a support plate 15 is fixedly connected to the top of the support platform 1, a guide rod 16 is fixedly connected to the outer wall of the support plate 15, a guide hole 14 is provided on the inner side of the second connecting plate 13, and the guide hole 14 is slidably connected to the guide rod 16.

[0024] When the strain gauge sensor 4 needs to be maintained, the staff can start the electric push rod 9 inside the first protective box 8, so that the output shaft 10 drives the first connecting plate 12 to move through the connecting piece 11. Because the first connecting plate 12 is fixedly connected to the side cover 5, it drives the side cover 5 to move and separate from the protective shell 2. At the same time, the second connecting plate 13 fixedly connected to the side cover 5 slides on the guide rod 16 through the guide hole 14, which can improve the stability of the side cover 5 when moving. In summary, the buried gas pipeline stress monitoring system can remove the side cover 5 from the protective shell 2, which is convenient for the staff to maintain the strain gauge sensor 4 inside the protective shell 2.

[0025] A wire hole 6 is formed on the inner side of the side cover 5 .

[0026] Among them, by opening a wire hole 6 on the inner side of the side cover 5, the staff can pull out the cables on the strain gauge sensor 4 inside the protective shell 2 through the wire hole 6, which is convenient for the staff to arrange the cables so that the strain gauge sensor 4 can be powered on for operation.

[0027] One end of the first protection box 8 is fixedly connected to a first box cover 18 by means of bolts.

[0028] The staff can screw the bolts into the first box cover 18 and the interior of the first protective box 8 , so that the first box cover 18 can cover the opening of the first protective box 8 and protect the electric push rod 9 inside the first protective box 8 .

[0029] A second protective box 19 is fixedly connected to the top of the support platform 1, a driving motor 20 is fixedly installed inside the second protective box 19, a spur gear 21 is fixedly connected to the output end of the driving motor 20, a rack 22 is arranged inside the second protective box 19, the spur gear 21 is meshed with the rack 22, one end of the rack 22 is fixedly connected to an L-shaped connecting plate 25, and the end of the L-shaped connecting plate 25 away from the rack 22 is fixedly connected to a fixing plate 26.

[0030] The staff can start the driving motor 20 inside the second protection box 19, so that the output end of the driving motor 20 drives the spur gear 21 to rotate, and the spur gear 21 meshes with the outer rack 22, thereby driving the rack 22 to move. Because the rack 22 is fixedly connected to the fixing plate 26 through the L-shaped connecting plate 25, the fixing plate 26 will be driven to move toward the gas pipeline body 17 and clamp and fix the gas pipeline body 17, thereby improving the stability of the gas pipeline body 17.

[0031] A guide groove 24 is formed inside the second protection box 19 , and a guide plate 23 is fixedly connected to the bottom of the rack 22 . The guide plate 23 is slidably connected to the guide groove 24 .

[0032] During the movement of the rack 22 , because the bottom of the rack 22 is fixedly connected with a guide plate 23 and a guide groove 24 is provided inside the second protective box 19 , the guide plate 23 will slide in the guide groove 24 , so that the rack 22 can move stably.

[0033] The top of the second protection box 19 is fixedly connected with a second box cover 27 by bolts.

[0034] The staff can screw the bolts into the second box cover 27 and the interior of the second protective box 19 , so that the second box cover 27 can cover the opening of the second protective box 19 and protect the drive motor 20 inside the second protective box 19 .

[0035] A base 28 is fixedly connected to the bottom of the support platform 1 .

[0036] Among them, by arranging a base 28 at the bottom of the support platform 1, the base 28 can stably support the support platform 1, so that the buried gas pipeline stress monitoring system can operate stably.

[0037] Working principle: When the buried gas pipeline stress monitoring system is in use, the strain gauge sensor 4 is arranged inside the protective shell 2 through the installation groove 3. The strain gauge sensor 4 can monitor the gas pipeline body 17. The protective shell 2 cooperates with the side cover 5 to effectively protect the strain gauge sensor 4, thereby extending the service life of the strain gauge sensor 4.

[0038] When the strain gauge sensor 4 needs to be maintained, the staff can start the electric push rod 9 inside the first protective box 8, so that the output shaft 10 drives the first connecting plate 12 to move through the connecting piece 11. Because the first connecting plate 12 is fixedly connected to the side cover 5, it drives the side cover 5 to move and separate from the protective shell 2. At the same time, the second connecting plate 13 fixedly connected to the side cover 5 slides on the guide rod 16 through the guide hole 14, which can improve the stability of the side cover 5 when moving. In summary, the buried gas pipeline stress monitoring system can remove the side cover 5 from the protective shell 2, which is convenient for the staff to maintain the strain gauge sensor 4 inside the protective shell 2.

[0039] In addition, the staff can start the driving motor 20 inside the second protection box 19, so that the output end of the driving motor 20 will drive the spur gear 21 to rotate, and the spur gear 21 will mesh with the outer rack 22, thereby driving the rack 22 to move, and at the same time, the guide plate 23 fixedly connected to the bottom of the rack 22 will slide in the guide groove 24 opened inside the second protection box 19, thereby improving the stability of the movement of the rack 22. Because the rack 22 is fixedly connected to the fixed plate 26 through the L-shaped connecting plate 25, it will drive the fixed plate 26 to move toward the gas pipeline body 17, and there are two fixed plates 26 distributed on both sides of the gas pipeline body 17, so that the two fixed plates 26 can clamp and fix the gas pipeline body 17 from both sides, thereby improving the stability of the gas pipeline body 17.
