[0022] Example

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 The technical solution in the embodiment of the present application effectively solves the technical problem that when other objects pass by the gas transmission pipe, the anti-leakage protection mechanism is easily damaged by collision, resulting in an increased risk of gas leakage. The overall idea is as follows:

[0024] In view of the problems existing in the prior art, the utility model provides a gas delivery pipe with an anti-leakage mechanism, which comprises a delivery pipe body 1, two protection mechanisms are arranged outside the delivery pipe body 1, each protection mechanism comprises a side plate 2, a mounting frame 3, a rotating shaft 4, a protection plate 5 and an opening 6, the side plate 2 is arranged outside the delivery pipe body 1, the mounting frame 3 is arranged outside the delivery pipe body 1, the two ends of the rotating shaft 4 are rotatably connected to the two ends of the mounting frame 3 respectively, the protection plate 5 is fixedly connected to the outside of the rotating shaft 4, the opening 6 is arranged on the upper surface of the protection plate 5, and the two protection plates 5 are in contact with each other on one side away from the rotating shaft 4. The two protective plates 5 are located between the two side plates 2, and a bolt 7 is arranged above the conveying pipe body 1. The external thread of the bolt 7 is connected with a nut 8. The bolt 7 is movably connected inside the two openings 6. By setting the protective plate 5 and cooperating with the side plate 2, the protective plate 5 is rotated upward to make the two protective plates 5 fit each other. At this time, the bolt 7 is passed through the two through holes, and the nut 8 and bolt 7 are connected to the outside of the bolt 7. At this time, the connection of the two protective plates 5 is completed. At this time, the two protective plates 5 are located between the two side plates 2. At this time, the leakage prevention mechanism is covered by the side plate 2 and the protective plate 5, which reduces the probability of damage to the leakage prevention mechanism, extends the service life of the leakage prevention mechanism, and also reduces the risk of gas leakage.

[0025] Both ends of the conveying pipe body 1 are fixedly installed with slide plates 9, and the side plates 2 are slidably connected to the outside of the slide plates 9 to facilitate the movement of the side plates 2. Threaded holes 10 are opened at both ends of the conveying pipe body 1, and the inside of each threaded hole 10 is threadedly connected with a first threaded rod 11. The two side plates 2 are located between the two first threaded rods 11 to facilitate the fixation of the side plates 2. Each of the slide plates 9 is slidably connected to the outside of a pressure plate 12, and the pressure plate 12 fits the outside of the side plate 2 to increase the contact surface between the threaded rod and the first threaded rod 11 so as to improve the stability of the fixation of the side plates 2. By setting the slide plate 9 and cooperating with the side plate 2, when it is necessary to repair the leak-proof mechanism, the nut 8 is rotated to release the connection between the nut 8 and the bolt 7, and the protective plate 5 is rotated downward at this time. At this time, the first threaded rod 11 is rotated to make the first threaded rod 11 away from the pressure plate 12, and the side plate 2 can be directly pushed to make the side plate 2 away from the leak-proof mechanism, thereby increasing the maintenance space, facilitating the maintenance of the staff, and improving the maintenance efficiency.

[0026] Two second threaded rods 13 are fixedly installed at both ends of the conveying pipe body 1, and the outside of each second threaded rod 13 is threadedly connected with a threaded sleeve 14. The two ends of the mounting frame 3 are slidably connected to the outside of the two second threaded rods 13, respectively, to facilitate the disassembly and assembly of the protective plate 5.

[0027] An observation port 15 is provided on the outside of each protective plate 5, and a baffle 16 is provided inside each observation port 15 for easy observation of the leakage prevention mechanism. A rotating shaft 17 is rotatably connected to the inside of each observation port 15, and the baffle 16 is fixedly connected to the outside of the rotating shaft 17 for the convenience of the baffle 16 to open or close the observation port 15. A limit plate 18 is fixedly installed on one end of each observation port 15 away from the rotating shaft 17, and the baffle 16 fits against the outside of the limit plate 18 to prevent the baffle 16 from moving toward the leakage prevention mechanism.

[0028] Working principle:

[0029] In the first step, the two ends of the mounting frame 3 are slidably connected to the outside of the two second threaded rods 13, and the threaded sleeve 14 is threadedly connected to the outside of the second threaded rod 13. At this time, the mounting frame 3 is installed, and the side plate 2 is slidably connected to the outside of the slide plate 9. At this time, the protective plate 5 is rotated upward to make the two protective plates 5 fit each other. At this time, the bolt 7 is passed through the two through holes, and the nut 8 bolt 7 is connected to the outside of the bolt 7. At this time, the connection of the two protective plates 5 is completed, and the first threaded rod 11 is rotated to make the first threaded rod 11 push the pressure plate 12, and the pressure plate 12 pushes the side plate 2 until the side plate 2 fits the protective plate 5. At this time, the anti-leakage mechanism is covered by the side plate 2 and the protective plate 5;

[0030] In the second step, when the leak prevention mechanism needs to be observed, the baffle 16 is rotated upward to open the observation port 15, and the staff can observe through the observation port 15. After the observation is completed, the baffle 16 is released and rotated downward to close the observation port 15.

[0031] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description.
