TECHNICAL FIELD

[0001] The utility model belongs to the technical field of sampling bottle, concretely relates to a water quality petroleum sampling bottle with expandable volume. BACKGROUND

[0002] In numerous scientific research and actual detection work, the sampling bottle is an indispensable work sampling tool. There are various structural forms of sampling bottles on the market. For example, the utility model patent with the application number CN201921638726.2 discloses a sewage sampling bottle for environmental detection, which comprises a sampling bottle and a sampling rack. A bottle cap is installed on the top of the sampling bottle. Two connecting grooves are symmetrically formed on the two sides of the sampling bottle. Two connecting legs are symmetrically installed on the bottom of the sampling rack. Limiting clamps connected with the connecting grooves on the two sides of the sampling bottle are movably installed on the inner side of the bottom of the connecting legs. A sampling rope is installed on the top of the sampling rack.

[0003] The sampling bottle provided by the above patent is convenient for individual sampling by setting the sampling bottle and the sampling rack for mutual cooperation. The connecting legs can be clamped into the connecting grooves and the bottle body is fixed by using the limiting clamps and auxiliary clamps on the connecting legs. In addition, a counterweight iron block is arranged on the bottom of the sampling bottle, so that the sampling bottle can sink better underwater, thereby ensuring multi-point sampling and improving the accuracy of the test results.

[0004] However, the sampling bottle provided by the above patent and the generally used surface water petroleum sampler can collect columnar water samples from the water surface to a depth of 30cm.

The collected sample needs to be used for analysis. How to add 25ml of n-hexane to the sample bottle filled with water sample without affecting the analysis requirements is a contradiction point, which seriously affects the accuracy of water sample analysis.

The bottom end of the upper splice part 2 is inserted into the inside of the lower splice part 1 in cooperation with the piston ring 3, and the upper splice part 2 and the lower splice part 1 are telescopically connected. This structure achieves the purpose of expanding the volume of the sampling bottle through the telescopic connection between the upper splice part 2 and the lower splice part 1, so as to facilitate the addition of reagents required for experiments into the sampling bottle after sampling is completed. The piston ring 3 seals the space between the upper splice part 2 and the lower splice part 1, thereby avoiding the problem of liquid leakage between the upper splice part 2 and the lower splice part 1. A bottle cap 4 is arranged at the opening at the top end of the upper splice part 2, which facilitates the plugging of the opening at the top end of the upper splice part 2.

When collecting water samples, the lower splice part 1 can meet the sampling requirements of the standard method for water quality petroleum. A plurality of limiting protrusions 11 are uniformly arranged at the top end of the inside of the lower splice part 1, which facilitates the mutual limiting of the lower splice part 1 and the upper splice part 2, thereby avoiding the separation of the lower splice part 1 and the upper splice part 2.

[0031] As shown in Figure 3 , the bottom end of the upper splice part 2 is provided with a plug 21, which facilitates the insertion into the inside of the lower splice part 1. A guide groove 22 is arranged at the position of the outside of the plug 21 corresponding to the limiting protrusion 11, and the guide groove 22 is longitudinally arranged, which facilitates the stable up-and-down movement of the upper splice part 2 and the lower splice part 1. A bearing 23 is arranged at the top end of the upper splice part 2, and a sampling tube 24 is arranged in the middle of the bearing 23, and the outer diameter of the sampling tube 24 is smaller than the diameter of the bearing 23. This structure facilitates the sampling of the petroleum instrument sampling tube during subsequent detection and analysis, and the bottle opening is smaller, which reduces the entry of volatile drugs into the air, and is more conducive to protecting the health of experimental analysis personnel compared with the traditional method.

[0032] As shown in Figure 1 and Figure 5 , the bottom end of the bottle cap 4 is provided with a tapered plug 41, and the diameter of the bottom end of the tapered plug 41 is smaller than the inner diameter of the sampling tube 24, which facilitates the smooth plugging of the sampling tube 24 by the bottle cap 4. The upper splice part 2, the lower splice part 1 and the bottle cap 4 are all made of brown glass, and the inner wall of the bottle opening of the lower splice part 1 and the tapered plug 41 are frosted.

[0033] As shown in Figure 4As shown, the piston ring 3 is made of rubber and facilitates sealing between the upper splice 2 and the lower splice 1. The piston ring 3 has a support frame 31 on its inner side, and an adapter 32 at the top of the support frame 31. The adapter 32 has external threads on its outer side.

[0041] Working principle: In use, according to the use requirements, the sampling bottle part of the lower splice 1 is inserted into the water surface below 30CM to collect water samples. After the water sample is collected, the upper splice is assembled, and the sampling bottle containing the water sample is taken back to the laboratory, and the upper splice 2 is pulled to expand the volume of the sampling bottle. Then the reagent required for the experiment can be injected into the sampling bottle. When the volume expansion is not enough, the expansion sleeve 5 can be installed on the sampling tube 24 to further expand the volume of the sampling bottle.

[0042] As described above, compared with the prior art, the sampling bottle is divided into an upper splice 2 and a lower splice 1, the upper splice 2 and the lower splice 1 are connected by insertion, and the bottom of the upper splice 2 is connected with a piston ring 3. This can seal the upper splice 2 and the lower splice 1, and prevent liquid leakage. At the same time, the expansion of the upper splice 2 and the lower splice 1 can expand the volume of the sampling bottle, which is convenient for the staff to continue adding reagents to the sampling bottle.
