[0024] To make the above objects, features, and advantages of the present invention more obvious and understandable, the following will make a detailed description of the specific implementation manners of the present invention with reference to the drawings in the specification.

[0025] In the following description, many specific details are set forth to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0026] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that can be included in at least one implementation manner of the present invention. The "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that excludes other embodiments.

[0027] Embodiment 1

[0028] Refer to Figure 1 , which is the first embodiment of the present invention. This embodiment provides a gas pipeline sampling device, which can achieve the effect of facilitating gas detection.

[0029] Specifically, it includes a bearing assembly 100, which includes a main pipeline 101 and a connecting pipeline 101a provided on the outer side of the main pipeline 101.

[0030] The closing assembly 200 includes 201 provided at one end of the connecting pipe 101a, a fixed frame 203 provided at one end of 201, and a first closing ring 202 provided at one end of the fixed frame 203.

[0031] The limiting assembly 300, and fixing plates 301 provided at both ends of the fixed frame 203 and connecting disks 301a provided above the fixing plates 301.

[0032] The bearing assembly 100 further includes a first splicing pipe 101b provided at one end of the connecting pipe 101a. One end of the first splicing pipe 101b is provided in the second splicing pipe 101c. A storage tank 102 is provided between the second splicing pipes 101c. A delivery pipe 102a is provided above the storage tank 102, and a detector 103 is provided above the delivery pipe 102a.

[0033] During use: When it is necessary to detect the gas inside the main pipe 101, two holes are opened on the outer side of the main pipe 101. By connecting the connecting pipe 101a and the first splicing pipe 101b, the closing assembly 200 is connected between the connecting pipe 101a and the first splicing pipe 101b. By connecting the first splicing pipe 101b and the second splicing pipe 101c, by applying a large force, the limiting assembly 300 is separated, thereby releasing the limit on the closing assembly 200. Then, by driving the closing assembly 200 to move upward, the connection between the connecting pipe 101a and the first splicing pipe 101b is opened through the closing assembly 200. At this time, the gas in the main pipe 101 enters the second splicing pipe 101c through the connecting pipe 101a and the first splicing pipe 101b, then enters the storage tank 102 and the delivery pipe 102a through the second splicing pipe 101c, and finally enters the detector 103, so as to detect the gas.

[0034] Embodiment 2

[0035] Refer to Figures 1 to 4 , which is the second embodiment of the present invention. This embodiment provides a gas pipeline sampling device, which can achieve the effect of preventing gas leakage after detection.

[0036] Specifically, it further includes that the closing assembly 200 further includes a closing plate 203a provided inside the fixed frame 203. A closing disk 204 is provided below the closing plate 203a, and a sealing ring is sleeved inside the closing disk 204.

[0037] The limiting assembly 300 includes a first elastic member 302 disposed between the connecting plates 301a, a first clamping plate 302a disposed on the outer side of the first elastic member 302, a second clamping plate 302b disposed at one end of the first clamping plate 302a, a connecting curved plate 303 disposed on the outer sides of the first clamping plate 302a and the second clamping plate 302b, and a second elastic member 303a disposed below the connecting curved plate 303. The first elastic member 302 is sleeved on the outer side of the rotating shaft and is a torsion spring. The second elastic member 303a is a compression spring. When the gas detection is completed, the connecting curved panel 303 is pressed to drive the first clamping plate 302a and the second clamping plate 302b to rotate through the connecting curved panel 303. By moving the closing plate 203a downward, the closing plate 203a drives the connecting block 304, the connecting plate 304a and the limiting rod 304b to move downward until the limiting rod 304b moves down to the first clamping plate 302a and the second clamping plate 302b. Under the action of the elastic force of the second elastic member 303a, the connecting curved panel 303 is reset through the second elastic member 303a. The connecting curved panel 303 drives the first clamping plate 302a and the second clamping plate 302b to reset and wrap the limiting rod 304b, thereby fixing the closing plate 203a to prevent gas leakage.

[0038] Connecting blocks 304 are provided at both ends of the closing plate 203a, a connecting plate 304a is provided below the connecting block 304, and a limiting rod 304b is provided below the connecting plate 304a.

[0039] Usage process: First, the staff applies a large force to drive the connecting block 304 to move upward, and the connecting block 304 drives the connecting plate 304a and the limiting rod 304b to move upward. During the upward movement of the limiting rod 304b, the first clamping plate 302a and the second clamping plate 302b will be squeezed until they are separated from the first clamping plate 302a and the second clamping plate 302b. During the upward movement of the closing plate 203a, the closing plate 203a drives the closing disk 204 to move upward, and the closing disk 204 is away from the middle of 201 and the first closed loop 202. At this time, 201 and the first closed loop 202 are in communication with each other, so that the gas in the main pipeline 101 flows into the storage box 102, and finally is detected by the detector 103, so that the gas will not overflow and cause danger.

[0040] Example 3

[0041] Reference Figures 1 to 4 , which is the third embodiment of the utility model, provides a gas pipeline sampling device that can achieve the effect of rapid splicing of the sampling device and the gas pipeline.

[0042] Specifically, it also includes a splicing assembly 400, which includes a splicing collar 401 arranged outside the first splicing pipe 101b, a convex plate is arranged above the splicing collar 401, a rotating shaft 401a is arranged inside the convex plate, a rotating rod 402 is arranged outside the rotating shaft 401a, a toggle plate 402a is arranged outside the rotating rod 402, a pressing plate 403 is arranged inside the splicing collar 401, a top plate 403a is arranged above the pressing plate 403, and a top rod 403b is arranged above the pressing plate 403. The rotating shaft 401a is arranged at the eccentric position of the rotating rod 402. The upper end of the top plate 403a is curved.

[0043] Usage process: first, put the second spliced ​​pipe 101c into the spliced ​​ring 401 and align it with the first spliced ​​pipe 101b, and use the toggle plate 402a to make the toggle plate 402a drive the rotating rod 402 to rotate. Since the rotating shaft 401a is connected to the eccentric point of the rotating rod 402, the rotating rod 402 swings downward and squeezes the top plate 403a and the top rod 403b. The top plate 403a and the top rod 403b squeeze the pressing plate 403, and then the pressing plate 403 squeezes the first spliced ​​pipe 101b and the second spliced ​​pipe 101c, so that the first spliced ​​pipe 101b and the second spliced ​​pipe 101c are connected and fixed, thereby realizing the convenient installation of the sampling device.
