In addition, the grading hoop device has the advantage of being easy to maintain and replace, because it can be disassembled individually without large-scale repairs of the entire pipeline system. The self-sealing grading hoop device outside the pipe further simplifies the maintenance process. It adopts self-sealing technology. When the hoop needs to be maintained or replaced, it can be self-sealed through simple operation without cutting the pipeline, which greatly reduces the maintenance cost and time.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] Reference Figure 1 - Figure 3 , the utility model provides an embodiment: a self-sealing grading hoop device outside a pipe, comprising a grading hoop shell 1, a closing plug 2 is slidably connected inside the grading hoop shell 1, a sliding sleeve 3 is arranged below the closing plug 2, a through hole 1 4 is opened inside the sliding sleeve 3, a through hole 2 5 is opened inside the sliding sleeve 3, a spring 1 7 is arranged inside the sliding sleeve 3, a limiting component is arranged at one end of the spring 1 7, and the limiting component is used to limit the spring 1 7, a fixing pin 10 is slidably connected inside the grading hoop shell 1, an outer wall of the fixing pin 10 is slidably connected to the inside of the sliding sleeve 3, a telescopic rod 11 is fixedly connected to the outer wall of the fixing pin 10, a spring 2 12 is sleeved on the outer wall of the telescopic rod 11, one end of the spring 2 12 is fixedly connected to the inside of the grading hoop shell 1, and the other end of the spring 2 12 is fixedly connected to the inside of the fixing pin 10, a discharge hole 6 is opened inside the grading hoop shell 1, and the limiting component comprises a slide plate 8, an upper surface of the slide plate 8 is fixedly connected to one end of the spring 1 7, an outer wall of the slide plate 8 is fixedly connected to a connecting block 9, and an outer wall of the connecting block 9 is fixedly connected to the inner wall of the grading hoop shell 1;
[0025] Specifically, when the pressure in the well increases, the sleeve 3 will slide inside the grading hoop shell 1 and apply pressure to the fixing pin 10. When the pressure reaches a sufficient level, the inclined surface of the outer wall of the fixing pin 10 will be pushed to slide inside the grading hoop shell 1, which will cause the spring 2 12 to contract. At the same time, the movement of the sleeve 3 will drive the spring 1 7 to move. One end of the spring 1 7 is fixed to the inner wall of the grading hoop shell 1 through the slide plate 8 and the connecting block 9. Therefore, the contraction of the spring 1 7 will cause the inner wall of the grading hoop shell 1 to move accordingly. When the through hole 2 5 preset inside the sleeve 3 coincides with the discharge hole 6, discharge can be carried out. As the pressure decreases, the rebound of the spring 1 7 will drive the sleeve 3 to move to its original position. At the same time, the rebound of the spring 12 will drive the fixing pin 10 back to the inside of the sleeve 3 to prepare for the next use.
[0026] Reference Figure 1 and Figure 4 The top of the grading hoop shell 1 is fixedly connected with an upper joint 13, the bottom of the grading hoop shell 1 is fixedly connected with a lower joint 20, the outer walls of the upper joint 13 and the lower joint 20 are rotatably connected with a rotating ring 14, the inner wall of the rotating ring 14 is fixedly connected with a rotating plate 15, the outer wall of the rotating plate 15 is rotatably connected to the interior of the upper joint 13, an arc-shaped slide groove 16 is opened inside the rotating plate 15, a sliding rod 17 is slidably connected to the interior of the rotating plate 15, the outer wall of the sliding rod 17 is slidably connected to the interior of the arc-shaped slide groove 16, the outer wall of the sliding rod 17 is fixedly connected with a clamping block 18, the outer wall of the clamping block 18 is slidably connected to the interior of the upper joint 13, the upper surface of the clamping block 18 is fixedly connected with a limiting block 19, and the outer wall of the limiting block 19 is slidably connected to the interior of the upper joint 13;
[0027] Specifically, in addition, by driving the rotating ring 14 to drive the rotating plate 15 to rotate inside the upper joint 13, the slide rod 17 can slide in the arc-shaped slide groove 16 inside the rotating plate 15, and then, the movement of the slide rod 17 will drive the block 18 to move. Under the guidance of the limit block 19, the block 18 will move to the inside of the casing. Similarly, the lower joint 20 will also realize the disassembly and assembly of the grading hoop, realize the easy disassembly and assembly of the grading hoop, and improve the convenience of operation.
[0028] Working principle: When the self-sealing grading hoop device outside the pipe is needed, when the pressure in the well increases, the sliding sleeve 3 slides in the grading hoop shell 1, and presses the fixed pin 10. Once the pressure is sufficient, the inclined surface pushes the fixed pin 10 to slide, causing the spring 2 12 to contract. The movement of the sliding sleeve 3 also drives the spring 1 7 to move. The spring 1 7 is fixed to the inner wall of the grading hoop shell 1 through the slide plate 8 and the connecting block 9, causing it to contract. When the through hole 2 5 in the sliding sleeve 3 coincides with the discharge hole 6, discharge can be carried out. When the pressure decreases, the spring 1 7 rebounds, driving the sliding sleeve 3 to reset, the spring 2 12 rebounds, and the fixed pin 10 returns to the sliding sleeve 3, ready for the next use.
[0029] In addition, the driving ring 14 rotates, driving the rotating plate 15, causing the slide bar 17 to slide in the arc-shaped slide groove 16, thereby moving the block 18, and the limit block 19 guides the block 18 to the inside of the casing. The lower joint 20 is similar, thereby realizing the disassembly and assembly of the grading hoop.
[0030] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
