[0023] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-4 , the present utility model provides a technical solution: an oil and gas pipeline leakage detection device, including an oil and gas pipeline body 1, and a support assembly 2 is arranged on the outer wall of the oil and gas pipeline body 1;

[0025] The support assembly 2 includes an upper hoop 21 and a lower hoop 22 located at the upper and lower ends of the oil and gas pipeline body 1. A support frame 23 is arranged at the bottom of the lower hoop 22. A groove is formed inside the upper hoop 21, and a detection assembly 24 is arranged inside the groove;

[0026] The detection component 24 includes a fixing frame 243 fixed in the inner groove of the upper clamping hoop 21. One end of the fixing frame 243 is movably connected with an installation box 242. The top of the installation box 242 is fixedly connected with a first clamping block 246 and a second clamping block 248. The second clamping blocks 248 are symmetrically distributed left and right about the bisector of the installation box 242. A limiting rod 247 is sleeved on the second clamping block 248. One end of the limiting rod 247 penetrates through the fixing frame 243 and is located at the top of the fixing frame 243. The limiting rod 247 forms a sliding connection with the fixing frame 243. This structure can make the installation box 242 move linearly by setting the limiting rod 247. This structure can facilitate the installation and disassembly of the installation box 242 and the limiting rod 247. A bushing 245 is sleeved on the top of the first clamping block 246. The top of the bushing 245 is movably connected with an adjusting screw 244. The bushing 245 and the adjusting screw 244 of this structure are connected by a bearing. When the adjusting screw 244 rotates, it drives the bushing 245 to move up and down without rotating. At the same time, it is also convenient for the disassembly of the bushing 245 and the installation box 242. One end of the adjusting screw 244 penetrates through the fixing frame 243 and is connected with the bushing 245. The adjusting screw 244 forms a movable connection with the fixing frame 243. This structure can push the bushing 245 and the installation box 242 to move up and down by rotating the adjusting screw 244. When the installation box 242 rises, it is separated from the oil and gas pipeline body 1, avoiding the friction damage of the fiber optic sensor 2412 inside the installation box 242 and the surface of the oil and gas pipeline body 1 during the disassembly of the installation box 242. A sealing gasket 241 is arranged at the bottom of the installation box 242. The bottom of the sealing gasket 241 is of an arc structure. This structure can ensure the tight fit between the installation box 242 and the oil and gas pipeline body 1 by setting the sealing gasket 241. An electromagnetic shielding layer 249, a waterproof layer 2410 and a buffer layer 2411 are arranged at the bottom of the installation box 242. The waterproof layer 2410 is arranged inside the electromagnetic shielding layer 249, and the buffer layer 2411 is arranged inside the waterproof layer 2410. The electromagnetic shielding layer 249 of this structure is an electromagnetic shielding plate, which is mainly used to shield the fiber optic sensor 2412 from electromagnetic interference and improve the detection accuracy of the fiber optic sensor 2412. The waterproof layer 2410 of this device is a waterproof coating. The buffer layer 2411 is buffer rubber, which can play a role in protecting and buffering the fiber optic sensor 2412 through the buffer layer 2411. A fiber optic sensor 2412 is installed inside the buffer layer 2411, and the fiber optic sensor 2412 is attached to the outer wall of the oil and gas pipeline body 1. The wiring of the fiber optic sensor 2412 of this device can pass through one side of the installation box 242 and the upper clamping hoop 21.

[0027] Working principle: When using this oil and gas pipeline leakage detection device, first, if necessary, the optical fiber sensor 2412 is snapped into the inner side of the buffer layer 2411 of the mounting box 242, and then the mounting box 242 is installed on the upper hoop 21. During installation, the first clamping block 246 and the second clamping block 248 at the top of the mounting box 242 are respectively aligned with the positions of the clamping sleeve 245 and the limiting rod 247 inside the upper hoop 21, and the first clamping block 246 and the second clamping block 248 are inserted into the inside of the clamping sleeve 245 and the limiting rod 247. At this time, the mounting box 242 can be installed inside the upper hoop 21. Subsequently, the adjusting screw 244 is rotated, so that the adjusting screw 244 moves downward during rotation and pushes the mounting box 242, making the sealing gasket 241 at the bottom of the mounting box 242 fit against the outer wall of the oil and gas pipeline body 1, and making the optical fiber sensor 2412 also fit against the outer wall of the oil and gas pipeline body 1 to complete the installation work.

[0028] Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
