[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] The protective device for oil and gas pipelines offers two technical solutions:

[0022] like Figure 1-3 The first embodiment is shown: it includes two main oil and gas pipeline bodies 1, which are joined together by flanges and bolts. A protective mechanism 2 is provided at the joint of the two main oil and gas pipeline bodies 1. The protective mechanism 2 includes two semi-circular plates 21, one above the other. Semi-circular grooves 6 are formed on the inner side of the two semi-circular plates 21. Bolt grooves 7 are formed on the front and back of the semi-circular plates 21. Fixing blocks 22 are fixedly connected to the left and right sides of the two semi-circular plates 21. U-shaped grooves 23 are formed inside the four fixing blocks 22. The inner wall of the lower U-shaped groove 23 is... A fixed rod 24 is fixedly connected between the front and back sides. A rotating rod 25 is rotatably connected to the surface of the fixed rod 24. A groove 26 is provided inside the rotating rod 25. A T-shaped slide rod 27 is slidably connected to the inner surface of the groove 26 and extends to the outside of the rotating rod 25. A cam handle 29 is rotatably connected to the end of the T-shaped slide rod 27 located outside the rotating rod 25. A limiting spring 28 is sleeved on the surface of the T-shaped slide rod 27 located inside the groove 26 and is located between the top of the inner wall of the groove 26 and the T-shaped head of the T-shaped slide rod 27.

[0023] The mechanism is designed specifically for protecting the joint of the main body 1 of the oil and gas pipeline. It can effectively prevent the joint of the main body 1 of the oil and gas pipeline from breaking due to pressure. Moreover, the protective mechanism 2 can be quickly assembled and installed through the cooperation of the rotating rod 25, the T-shaped slide rod 27 and the cam handle 29, which improves the convenience of the device during use.

[0024] like Figure 1 , 2The second embodiment shown in Figure 4 differs from the first embodiment in that: two buffer components 3 are fixedly connected to opposite sides of the upper and lower semicircular plates 21. The buffer components 3 consist of a sleeve rod, a sliding rod, and a buffer spring. The movable ends of the two buffer components 3 are fixedly connected to arc-shaped support plates 4. Multiple fixed anchors 5 are fixedly connected at equal intervals at the bottom of the lower arc-shaped support plate 4. Airbags 8 are embedded in the interior of the two semicircular annular grooves 6. An inflation nozzle 9 is threadedly connected to the top of the semicircular plate 21, and the inflation nozzle 9 passes through the semicircular plate 21 and communicates with the interior of the airbag 8. The arc-shaped support plate 4 consists of a double-layer shell 41 and multiple V-shaped support plates 43. The interior of the double-layer shell 41 forms a cavity 42 due to the double-layer design. Multiple V-shaped support plates 43 are fixed at equal intervals inside the cavity 42.

[0025] An airbag 8 is installed inside the protective mechanism 2 to wrap and protect the splicing area, thereby improving the protective effect. Moreover, the special design of the upper and lower arc-shaped support plates 4 provides a double protection effect.

[0026] In use, the lower arc-shaped support plate 4 is inserted into the ground through the fixing anchor 5, so that the lower semicircular plate 21 is below the splice of the two oil and gas pipeline bodies 1. Then, the upper semicircular plate 21 is placed directly above the lower semicircular plate 21 and aligned. Then, the cam handle 29 is pulled to increase the length of the T-shaped slide bar 27 outside the rotating rod 25, and the rotating rod 25 is rotated so that the cam handle 29 enters above the upper fixing block 22. Finally, the cam handle 29 is rotated so that the protruding part of the cam handle 29 contacts the top of the fixing block 22 and is pressed tightly by the action of the limiting spring 28. When providing protection, the airbag 8 provides soft protection, effectively preventing damage to the splice of the two oil and gas pipeline bodies 1. Moreover, the double-layer design of the arc-shaped support plate 4 further increases the protection effect. Thus, the splice of the two oil and gas pipeline bodies 1 forms double protection through the action of the airbag 8 and the arc-shaped support plate 4.
