[0002] In chemical production, there are often situations where it is necessary to take liquid samples from drum containers, underground storage tanks, low-level tanks, and underground pools. Due to the special location of these sampling points, it is difficult for personnel to operate during sampling. At the same time, in order to ensure the accuracy of sampling, it is generally required to take samples from the upper, middle, and lower positions of the liquid in the drum containers, storage tanks, and pools. This greatly increases the difficulty of sampling and also creates significant safety hazards.
[0003] Therefore, a fast, safe, and convenient sampling device is of paramount importance. Utility Model Content
[0004] The purpose of this invention is to provide a fully automatic sampling device that addresses the above-mentioned shortcomings, solving the problem in the prior art that it is impossible to efficiently sample different sampling devices or sampling positions at the upper, middle, and lower positions.
[0005] This utility model is achieved through the following solution:
[0006] A fully automatic sampling device includes a power unit, a sampling bottle, and a sampling structure. The sampling structure is provided with a power mating hole that mates with the power unit and a sampling mating hole that mates with the sampling bottle, and a connecting hole is provided between the power mating hole and the sampling mating hole. The sampling structure is provided with a sampling tube of a predetermined length. When the sampling bottle and the power unit are assembled on the sampling structure, the power unit can draw the sampling bottle into negative pressure to draw the liquid medium into the sampling bottle.
[0007] Based on the structure of the above-mentioned fully automatic sampling device, the power unit includes an extraction tube and a portable vacuum pump; the extraction tube and the portable vacuum pump are connected as one unit, and the extraction tube is provided with a connecting tube that mates with the power mating hole; the power unit and the sampling structure are connected as a whole through the connecting tube.
[0008] Based on the structure of the above-mentioned fully automatic sampling device, the power mating hole is provided with an internal thread, the connecting pipe is provided with an external thread, and the power unit and the sampling structure are connected as one unit through threaded mating.
[0009] Based on the structure of the above-mentioned fully automatic sampling device, the sampling structure includes a horizontal conveying pipe and a vertical conveying pipe. The sampling pipe and the vertical conveying pipe are respectively arranged on both sides of the horizontal conveying pipe, and the sampling pipe, the horizontal conveying pipe, and the vertical conveying pipe are internally connected. The sampling pipe is arranged parallel to the vertical conveying pipe.
[0010] Based on the structure of the above-mentioned fully automatic sampling device, the power mating hole is located on the side wall of the conveying vertical pipe, and the sampling mating hole is located at the bottom of the conveying vertical pipe.
[0011] Based on the structure of the above-mentioned fully automatic sampling device, the conveying channel inside the horizontal conveying pipe is the main channel, and the conveying channel inside the vertical conveying pipe is the secondary channel; the vertical conveying pipe is provided with a gradient tube and an extension tube that cooperate with the main channel; the gradient tube is connected to the main channel, the extension tube is connected to the gradient tube, and both the gradient tube and the extension tube are located in the secondary channel.
[0012] Based on the structure of the aforementioned fully automatic sampling device, the size of the insertion tube is not greater than the inner diameter of the sampling bottle, and the insertion tube is spaced at a predetermined distance from the side wall of the sampling bottle opening.

[0017] 1. This solution sets one end of the sampling structure as a sampling tube of a certain length. According to the sampling requirements, the sampling tube can be extended to the upper, middle and lower positions of the part to be sampled. The power unit automatically draws the medium in the predetermined area into the sampling bottle, thus realizing a simple, fast and efficient sampling operation. By setting a connecting hole between the power mating hole and the sampling mating hole, the power unit can extract the gas in the sampling bottle, so that the medium is drawn into the sampling bottle for storage, instead of being directly extracted by the power unit.
[0018] 2. This sampling device uses an external portable vacuum pump as its power source. The vacuum pump generates a negative pressure vacuum, and then, through the special internal design of the sampling device, the gas and liquid phases are isolated and flow separately.

[0025] Example 1
[0026] like Figure 1 As shown, this utility model provides a technical solution:
[0027] A fully automatic sampling device includes, but is not limited to, a power unit 1, a sampling bottle 2, and a sampling structure 3; the sampling structure 3 is provided with a power mating hole 4 that mates with the power unit 1 and a sampling mating hole 5 that mates with the sampling bottle 2, and a connecting hole is provided between the power mating hole 4 and the sampling mating hole 5; the sampling structure 3 is provided with a sampling tube 31 of a predetermined length; when the sampling bottle 2 and the power unit 1 are assembled on the sampling structure 3, the power unit 1 can draw the sampling bottle 2 into negative pressure to draw the liquid medium into the sampling bottle 2.
[0028] Based on the above structure, this solution sets one end of the sampling structure 3 as a sampling tube 31 with a certain length. According to the sampling requirements, the sampling tube 31 can be extended to the upper, middle and lower positions of the part to be sampled. The power unit 1 automatically draws the medium in the predetermined area into the sampling bottle 2, thus realizing a simple, fast and efficient sampling operation. By setting a connecting hole between the power mating hole 4 and the sampling mating hole 5, the power unit 1 can extract the gas in the sampling bottle 2, so that the medium is drawn into the sampling bottle 2 for storage, instead of being directly extracted by the power unit 1.
[0029] As an example, the power unit 1 may include an extraction tube 11 and a portable vacuum pump 12; the extraction tube 11 and the portable vacuum pump 12 are connected as one unit, and a connecting tube that mates with the power mating hole 4 is provided on the extraction tube 11; the power unit 1 and the sampling structure 3 are connected as a whole through the connecting tube.
[0030] Based on the above structure, the portable vacuum pump 12 is convenient for outdoor operations. The separate arrangement of the power unit 1 and the sampling structure 3 makes it easy to store the entire device and effectively avoids damage to the portable vacuum pump 12.
[0031] As an example, the power mating hole 4 can be provided with an internal thread, and the connecting pipe can be provided with an external thread. The power unit 1 and the sampling structure 3 are connected as one unit through the threaded mating.
[0032] Based on the above structure, by adopting a threaded connection for the power unit 1, the purpose of quick disassembly and quick installation can be achieved. On the one hand, the overall sampling efficiency can be improved, and on the other hand, the power unit 1 and the sampling structure 3 can be stored separately to ensure safe use.
[0033] As an example, the sampling structure 3 may include a horizontal conveying pipe 32 and a vertical conveying pipe 33. The sampling pipe 31 and the vertical conveying pipe 33 are respectively arranged on both sides of the horizontal conveying pipe 32, and the sampling pipe 31, the horizontal conveying pipe 32, and the vertical conveying pipe 33 are internally connected. The sampling pipe 31 may be arranged parallel to the vertical conveying pipe 33.
[0034] The power mating hole 4 is located on the side wall of the conveying vertical pipe 33, and the sampling mating hole 5 is located at the bottom of the conveying vertical pipe 33.
[0035] Based on the above structure, by setting the sampling tube 31 and the conveying vertical tube 33 at intervals, the sampling acquisition end and the sampling collection end can be separated, so that the sampling acquisition end has enough space for sampling, and sampling operations can be carried out more flexibly in locations that are difficult to operate.
[0036] As an example, the conveying channel provided in the horizontal conveying pipe 32 is the main channel 34, and the conveying channel provided in the vertical conveying pipe is the secondary channel 35; the vertical conveying pipe 33 is provided with a gradient pipe 36 and an extension pipe 37 that cooperate with the main channel 34; the gradient pipe 36 is connected to the main channel 34, the extension pipe 37 is connected to the gradient pipe 36, and both the gradient pipe 36 and the extension pipe 37 are provided in the secondary channel 35.
[0037] The size of the insertion tube 37 is not greater than the inner diameter of the sampling bottle 2, so that the insertion tube 37 is spaced at a predetermined distance from the side wall of the bottle mouth of the sampling bottle 2.
[0038] Based on the above structure, during sampling, the power unit 1 is activated, and the liquid medium enters the gradient tube 36 through the main channel 34, and finally is discharged into the sampling bottle 2 through the insertion tube 37. When the sampling bottle 2 and the sampling fitting hole 5 are connected as one unit, the distance between the insertion tube 37 and the side wall of the bottle mouth of the sampling bottle 2 can provide a path for air flow. The extracted air flows towards the secondary channel 35 along the space between the insertion tube 37 and the side wall of the bottle mouth of the sampling bottle 2, and is finally discharged by the portable vacuum pump 12. In the whole process, gas-liquid separation is achieved.
[0039] As an example, the sampling bottle 2 has an external thread at its opening and an internal thread in the sampling mating hole 5, with the sampling bottle 2 and the sampling mating hole 5 threadedly engaged. This allows for quick handling of the sampling bottle 2.
[0040] As an example, a limiting block 38 for limiting the opening of sampling bottle 2 is provided in the secondary channel 35. The limiting block 38 is located at the end of the secondary channel 35 near the main channel 34.
[0041] Based on the above structure, the extreme position of the sampling bottle 2 can be restricted by setting the limiting block 38, so that the sampling bottle 2 can be fixed more quickly and stably.
[0042] As an example, the end plate of the sampling tube 31 away from the conveying horizontal tube 32 can be made into a sharp shape, and a filter screen 39 can also be provided on the end of the sampling tube 31.
[0043] Based on the above structure, the filter screen 39 can be used to sample impurities, ensuring the smooth flow of the pipeline. The end of the sampling tube 31 is made into a sharp shape, which can be inserted into the medium to be sampled more quickly.
[0044] As an example, a scale (not shown) can be set on the outer surface of the sampling tube 31. The depth of the sampling tube 31 inserted into the medium to be tested can be observed through the scale, so as to achieve fast and accurate positioning.
[0045] As an example, the fully automated sampling device is made entirely of PVC, PP, PTFE, glass, or metal. It has a simple structure, small size, and is easy to carry and clean. Quick-connect couplings facilitate connection and disassembly.
[0046] As an example, sampling bottle 2 is a glass bottle or a PTFE bottle, which is convenient for observing the liquid level.
[0047] This sampling device uses an external portable vacuum pump 12 as a power source. The vacuum pump generates a negative pressure vacuum, and then, through the special internal design of the sampling device, the gas and liquid phases are isolated and flow separately. The gas is discharged with the vacuum pump, while the liquid enters the sampling bottle 2 through the sampler insertion tube 37 under the action of negative pressure. The whole process achieves closed sampling, avoiding human contact, and is particularly suitable for sampling toxic, harmful, corrosive, and irritating liquids.
[0048] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
