[0002] Natural gas is a mixed gas mainly composed of methane (CH4). It is a combustible gas resource formed underground and usually exists in underground oil and gas fields together with petroleum. Natural gas is a clean and energy-efficient energy source and is widely used in heating, power generation, industrial production and transportation.

[0003] When natural gas is in use, in order to avoid safety hazards caused by sulfide detection exceeding the standard in natural gas, it is necessary to detect the sulfide in natural gas. Most of the existing detection methods are to put the natural gas in a detection bag, and then place the detection device probe in the detection bag for detection.

The structure and principle thereof can be known to those skilled in the art through technical manuals or conventional experimental methods.

[0036] Working principle:

[0037] First, through the connecting mechanism 2 set on one side of the sulfide detector 1, the connecting pipes 22 are fixedly connected to both ends of the square tube 21, and the outer walls of the two connecting pipes 22 are fixedly sleeved with flanges 23, so as to facilitate the connection with the natural gas pipeline, so that the pipeline can flow natural gas normally, and the first connecting box 24 and the second connecting box 25 are fixed on the outer wall of the square tube 21, and the first connecting box 24 and the second connecting box 25 are connected to the inside of the square tube 21, and the other two ends of the first connecting box 24 and the third connecting box 26 are connected to the second connecting box 25, and at the same time, the first connecting box 24 and the third connecting box 26 are also connected to the second connecting box 25, so that the natural gas will pass through the first connecting box 24 and pass through the first connecting box The box 24 enters the interior of the second connection box 25, and at the same time enters the interior of the third connection box 26 through the second connection box 25, and then enters the interior of the square tube 21 through the third connection box 26. The detector probe 11 electrically connected through the output end of the detector probe 11 is fixedly installed on the inner wall of the second connection box 25, thereby effectively realizing that the detector probe 11 can detect the natural gas passing through the interior of the second connection box 25, and the sulfide situation is displayed through the sulfide detector 1. The push rod 215 can drive the rotation of the rotating rod 212, and the outer wall of the rotating rod 212 and the top of the square tube 21 are sealed and rotated. Two limit strips 216 are fixed through the inner wall of the square tube 21, and the sliding plate 29 can be limited by the two limit strips 216 The toothed plate 214 is fixed to the sliding plate 29 away from the first connecting box 24 and the third connecting box 26. At the same time, the first gear 213 fixedly sleeved on the outer wall of the rotating rod 212 is meshed with the toothed plate 214 away from the sliding plate 29. Therefore, the rotating rod 212 is driven to rotate by pushing the push rod 215, so that the first gear 213 can realize the toothed plate 214 to move to both sides. At the same time, the sliding plate 29 can be limited by the second limiting block 211 and the first limiting block 210. When one side of the sliding plate 29 contacts the second limiting block 211, the natural gas inside the square tube 21 can enter the first connecting box 24 and pass through the second connecting box 25. And through the third connection box 26, when entering the interior of the square tube 21, the detector probe 11 can detect the sulfide of natural gas. When the other side of the sliding plate 29 contacts the first limit block 210, the first connection box 24 and the third connection box 26 can be closed, so as to prevent the natural gas inside the square tube 21 from entering the interior of the second connection box 25. Therefore, the detector probe 11 will not detect the sulfide inside the natural gas, and can be detected as needed. During the detection, the natural gas can be detected by flowing inside the second connection box 25, and the natural gas inside the second connection box 25 can also be detected as non-flowing. When the sliding plate 29 contacts the second limit block 211,The limiting plate 28 fixed on the inner wall of the square tube 21 can contact the limiting plate 28 fixed on the sliding plate 29, so that the natural gas inside the square tube 21 can better enter the first connection box 24;

[0038] By means of the limiting mechanism 3 provided at the top of the square tube 21, the second gear 31 in the limiting mechanism 3 is fixedly sleeved inside the rotating rod 212, and at the same time fixed to the top outer wall of the square tube 21 by the limiting box 34, the sliding rod 33 can be limited by the limiting box 34, the rack 32 can be limited by the sliding rod 33, and the side of the rack 32 close to the second gear 31 is meshed with the outer wall of the second gear 31, so that the rack 32 can limit the second gear 31, and after the second gear 31 is limited, the second gear 31 can limit the rotating rod 212, and then The rotating rod 212 will not rotate, and the sliding push plate 37 can drive the sliding rod 33 to slide, and the limiting box 34 can limit the limiting rod 35. The limiting rod 35 is located inside the limiting box 34 and the outer wall is sleeved with a tension spring 36. Therefore, the sliding push plate 37 can be pushed under the tension of the tension spring 36. After the sliding push plate 37 is pushed, the rack 32 can be brought close to the second gear 31, thereby avoiding the rotating rod 212 from rotating due to error. When the rotating rod 212 needs to rotate, it can be moved to the side away from the second gear 31 by pushing the sliding push plate 37.

[0039] Through the filtering mechanism 4 set on the first connecting box 24, through the fixed frame 41 fixed on the side of the first connecting box 24 away from the third connecting box 26, the fixed frame 41 is connected with the interior of the first connecting box 24, so as to facilitate the sliding frame 42 to slide from the inner wall of the fixed frame 41 into the interior of the first connecting box 24, and the two limit frames 44 fixed on the inner wall of the sliding frame 42 can limit the filter plate 45, so as to facilitate the sliding of the filter plate 45, and the filter plate 45 can be limited by the two limit frames 44, and a sponge 43 is placed between the filter plate 45 and the side of the sliding frame 42 away from the square tube 21, and then after the sliding frame 42 is placed into the interior of the fixed frame 41 and the first connecting box 24, the natural gas that enters the interior of the second connecting box 25 can pass The filter plate 45 and the sponge 43 are limited, thereby preventing particles from falling on the detector probe 11, and preventing the detector probe 11 from being affected by particles and causing non-standard sulfide detection.
