Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0028] The present utility model provides a sampling device for natural gas as shown in Figures 1-3 which includes a grip 1 and a fuselage 4 installed on the outer wall of the upper end of the grip 1;

[0029] The outer wall of the left end of the fuselage 4 is fixedly connected with an air inlet pipe 3;

[0030] A plurality of air inlet holes 23 are opened on the circular outer wall of the air inlet pipe 3;

[0031] A sampling bottle 7 is arranged on the right side of the fuselage 4, and a suction pump a 11 is arranged inside the fuselage 4 to guide natural gas into the sampling bottle 7 for collection. When sampling natural gas, hold the grip 1 and align the air inlet pipe 3 with the position where natural gas needs to be sampled, and then turn on the suction pump a 11. The suction pump a 11 will guide the natural gas into the sampling bottle 7 through the air inlet holes 23 opened on the air inlet pipe 3 for collection;

[0032] The outer wall of the lower end of the grip 1 is fixedly connected with a fixing plate 10. A plurality of threaded holes 9 are equidistantly opened on the upper end outer wall of the fixing plate 10 to store the sampling bottles 7. The plurality of sampling bottles 7 can be respectively screwed into the threaded holes 9 on the fixing plate 10. When it is necessary to carry and replace the sampling bottles 7, they can be carried conveniently and the sampling bottles 7 can be replaced quickly.

[0033] As shown in Figure 1 and Figure 3As shown, a connecting plate 18 is fixedly connected to the outer wall of the right end of the sampling bottle 7. A thread a19 is provided on the circular outer wall of the connecting plate 18, and the thread a19 is screwed with the threaded hole 9. The fixing plate 10 and the handle 1 are fixedly connected by welding.

[0034] When disassembling and assembling the sampling bottle 7, unscrew the sampling bottle 7 from the fuselage 4, then insert the right end connecting plate 18 of the sampling bottle 7 into the threaded hole 9, and through the screwing between the thread a19 and the threaded hole 9, the position of the sampling bottle 7 can be restricted.

[0035] As Figure 4 shown, a fixing ring 20 is sleeved on the circular outer wall of the intake pipe 3 to the right. A protective net 22 is arranged inside the fixing ring 20. A thread b21 is provided on the circular outer wall of the intake pipe 3, and a thread groove 24 is opened on the circular inner wall of the fixing ring 20.

[0036] By screwing between the thread groove 24 opened on the inner wall of the fixing ring 20 and the thread b21, the fixing ring 20 is restricted on the intake pipe 3. The intake hole 23 on the intake pipe 3 is blocked by the protective net 22 inside the fixing ring 20, which can avoid the situation that impurities enter the inside of the intake pipe 3 through the intake hole 23.

[0037] As Figure 3 shown, a fixed end 6 is fixedly connected to the outer wall of the right end of the fuselage 4. A push rod 14 is fixedly connected inside the fixed end 6. A connecting pipe 8 screwed inside the fixed end 6 is fixedly connected to the outer wall of the left end of the sampling bottle 7. A baffle 15 is fixedly connected to the leftmost side of the circular inner wall of the connecting pipe 8. A sealing plate 17 is arranged on the right side of the baffle 15. A plurality of springs 16 are fixedly connected between the sealing plate 17 and the baffle 15 to restrict the position of the sealing plate 17.

[0038] When the sampling bottle 7 is fixed on the fixed end 6, first screw the connecting pipe 8 into the fixed end 6. At this time, the push rod 14 will push the sealing plate 17 to the right and drive the spring 16 to stretch. At this time, the natural gas inside the fuselage 4 can be guided into the sampling bottle 7 for storage. When unscrewing the sampling bottle 7, the sealing plate 17 lacks the restriction of the push rod 14, and the spring 16 resets, driving the sealing plate 17 to fit the baffle 15 to seal the sampling bottle 7 and prevent gas leakage.

[0039] As Figure 1 and Figure 2 shown, a switch 2 is arranged on the circular outer wall of the left end of the handle 1. A processor 12 is arranged inside the fuselage 4 and on the right side of the suction pump a11 to analyze the natural gas value. A suction pump b13 is arranged on the right side of the processor 12 to guide the analyzed natural gas into the sampling bottle 7. A display screen 5 is arranged on the circular outer wall of the front end of the fuselage 4 to limit the data analyzed by the processor 12.

[0040] By pressing the switch 2, the suction pump a11 and the suction pump b13 can be turned on to work simultaneously to guide the gas. The natural gas passing through the suction pump a11 will be temporarily analyzed for its components by the processor 12 and displayed on the display screen 5, and then guided by the suction pump b13 into the sampling bottle 7 for storage.

[0041] The implementation principle of this embodiment is as follows: When sampling natural gas, hold the grip 1 and align the intake pipe 3 with the position where natural gas needs to be collected. Then turn on the suction pump a11, and the suction pump a11 will guide and collect the natural gas into the sampling bottle 7 through the intake holes 23 opened on the intake pipe 3. Multiple sampling bottles 7 can be respectively screwed into the threaded holes 9 on the fixed plate 10. When it is necessary to carry and replace the sampling bottle 7, it can be carried conveniently and the sampling bottle 7 can be replaced quickly.
