[0027] Example 2

[0028] As Figures 1 to 4 shown in a kind of oil and gas storage and transportation leak detection device, including upper detection ring 1 and lower detection ring 2, upper detection ring 1 and lower detection ring 2 between forming circular space, for adapting the shape of pipeline, upper detection ring 1 and lower detection ring 2 rear side between being connected with hinge 4, i.e. when upper detection ring 1 and lower detection ring 2 are fixed on the pipeline, it can be detected whether there is leakage in the pipeline connection by the detection module 3 arranged in its upper detection ring 1;And when detecting leakage, the fixing of upper detection ring 1 and lower detection ring 2 can be released, lower detection ring 2 is automatically opened downward under the condition of gravity, then the whole detection device is disassembled, i.e. the leakage of pipeline can be easily investigated, repaired and handled. During detection, the contact between pipeline connection and outside air needs to be isolated to avoid the increase of air concentration affecting the detection accuracy of the device on the leakage, therefore first rubber ring 5 is symmetrically arranged on the inner wall of upper detection ring 1, and second rubber ring 6 is symmetrically arranged on the inner wall of lower detection ring 2, first rubber ring 5 and second rubber ring 6 are both arranged in semicircle, and then when upper detection ring 1 and lower detection ring 2 are merged, the air in the device can be isolated by first rubber ring 5 and second rubber ring 6;It can be understood that the circular space formed by upper detection ring 1 and lower detection ring 2 is slightly larger than the actual outer diameter of the pipeline to provide enough space for the operation of detection module 3.

[0029] A first platform 7 is provided at the bottom front side of the upper detection ring 1. Screws 8 are symmetrically embedded in the first platform 7. Specifically, the contact portion between the screws 8 and the first platform 7 is a protruding thread, ensuring that the screws 8 are stably placed in the first platform 7. A first through groove 9 and a second through groove 10 are formed inside the screws 8. The first through groove 9 is located above the second through groove 10, and the inner diameter of the first through groove 9 is larger than that of the second through groove 10. When an adjusting rod 11 is slidably provided between the first through groove 9 and the second through groove 10, it indicates that the maximum diameter of the adjusting rod 11 will be smaller. The adjustment rod 11 is positioned at the top of the screw 8 via an extension head 17, and a spring 12 is also fitted onto the adjustment rod 11. The spring 12 is connected between the bottom of the extension head 17 and the first through groove 9. Initially, the adjustment rod 11 protrudes upward from the top of the screw 8 under the action of the spring 12. Under a certain applied force, the maximum downward stroke of the adjustment rod 11 within the screw 8 is "until the extension head 17 abuts against the top of the screw 8", at which point the spring 12 is compressed.

[0030] Furthermore, a second platform 16 is provided on the front side of the lower detection ring 2. The second platform 16 and the first platform 7 can fit tightly together to ensure the sealing of the device during detection. Bolts 19 are symmetrically embedded in the second platform 16. The bolts 19 are also securely placed in the second platform 16 by protruding threads. A third through groove 20 and a fourth through groove 21 are opened in the bolts 19. The third through groove 20 is located above the fourth through groove 21, and the inner diameter of the third through groove 20 is equal to that of the second through groove 10 and smaller than that of the fourth through groove 21. That is, the adjusting rod 11 can move downward into the third through groove 20.

[0031] Example 3

[0032] like Figures 1 to 4 The oil and gas storage leakage detection device shown can be used by placing an upper detection ring 1 and a lower detection ring 2 on a pipeline, and using the circular space formed by the upper detection ring 1 and the lower detection ring 2 for detection. During this process, the air inside the device is isolated by a first rubber ring 5 and a second rubber ring 6, which is conducive to accurate oil and gas leakage detection.

[0033] In this embodiment, a conical block 13 is provided at the bottom of the adjusting rod 11 so that the adjusting rod 11 can enter the fourth through groove 21 by reducing the size of the lower part; correspondingly, a sliding groove 14 is symmetrically opened at the lower part of the screw 8, and a ball bearing 15 is slidably arranged in the sliding groove 14. At the same time, the ball bearing 15 is also located in the second through groove 10 above the conical block 13. Under normal conditions, the adjusting rod 11 protrudes upward from the top of the screw 8 under the action of the spring 12, that is, the conical block 13 is located in the second through groove 10. At this time, the ball bearing 15 is squeezed by the conical block 13 and slides outward in the sliding groove 14. Conversely, when the adjusting rod 11 moves downward, it can drive the conical block 13 to move downward. At this time, the ball bearing 15 is no longer squeezed and automatically moves inward in the sliding groove 14.

[0034] It can be understood that the staff can manually hold the lower detection ring 2 against the pipeline during installation, and then rotate the upper detection ring 1 for fixation. When fixing, the expansion head 17 needs to be pressed to drive the adjusting rod 11 to move downward in the screw rod 8, at this time the spring 12 is compressed, and the ball 15 is located inside the sliding groove 14; when the upper detection ring 1 is rotated to the first platform 7 and the second platform 16 are attached, at this time the screw rod 8 is also inserted into the bolt 19, and then stop pressing the expansion head 17, the spring 12 is stretched to drive the adjusting rod 11 to move upward, and then drive the tapered block 13 to move upward to extrude the ball 15 to slide out of the sliding groove 14, because the diameter of the fourth through groove 21 is larger than that of the third through groove 20, so the ball 15 will abut against the top of the fourth through groove 21, and through the operation of fixing the screw rod 8 in the bolt 19, the fixation of the upper detection ring 1 and the lower detection ring 2 is indirectly realized, which cooperates with the detection of oil and gas leakage.

[0035] Therefore, when the leakage condition of the pipeline interface is detected, the ball 15 can be quickly moved into the sliding groove 14 by pressing the expansion head 17 downward, so as to no longer abut against the fourth through groove 21, and then stop pressing the expansion head 17 to drive the adjusting rod 11 to move upward, so as to no longer realize the fixation of the bolt 19, and the lower detection ring 2 will rotate out downward under the action of gravity in the state of not being supported, thereby realizing the quick disassembly of the detection device.

[0036] Embodiment 4

[0037] In order to further increase the disassembly speed, an auxiliary table 18 is further provided outside the top of the screw rod 8, and the staff can quickly position the expansion head 17 through the auxiliary table 18 to press the expansion head 17; Furthermore, an indicator light 22 is arranged on the top of the upper detection ring 1, and the indicator light 22 is electrically connected with the detection module 3, so that when the detection module 3 detects oil and gas leakage, the indicator light 22 can be quickly flashed to show a red light, indicating the staff to take the next step.
