The lengths of the three first hoses 14 are short, medium and long, respectively, and are used to absorb white wine samples from the bottom, middle and top of the wine tank, respectively. The second fixed disk 13 is fixedly connected to the fixed rod 12. The second fixed disk 13 is located at the first Above the fixed disk 11, six square grooves are provided on the second fixed disk 13, and the fixing frames 19 are rotatably connected to the square grooves of the second fixed disk 13. The fixing frames 19 are divided into three groups, and each group of fixing frames 19 is composed of two symmetrically arranged fixing frames 19. A base plate 110 is rotatably connected between the symmetrically arranged fixing frames 19. The sample tanks 17 are all placed on the base plate 110, and the sample tanks 17 are snap-fitted with the fixing frames 19.

The second hose 15 is connected between the sealing cover 111 and the detector 1, and the second hose 15 connects the sample tank 17 with the detector 1 through the small holes on the sealing cover 111.

[0041] like Figure 5-Figure 7 As shown, it also includes a telescopic mechanism that can adapt to wine tanks of different depths. The telescopic mechanism includes a telescopic member 2 and a telescopic rod 21. The telescopic rod 21 is fixedly connected to the bottom center of the first fixed plate 11. The telescopic member 2 is fixedly connected to the bottom of the first fixed plate 11. The telescopic rod 21 is located inside the telescopic member 2. The telescopic member 2 is composed of five fixed plates and five groups of folding rods. Each group of folding rods includes three folding rods. A fixed plate is rotatably connected between each group of folding rods. The telescopic end of the telescopic rod 21 is fixedly connected to the lowest fixed plate. The bottoms of three first hoses 14 of different lengths are fixedly connected to the first fixed plate, the third fixed plate and the fifth fixed plate respectively, and the bottoms of the first hoses 14 are all connected to the fixed plates.

[0042] Liquor is prone to excessive heavy metal content during production and storage due to environmental pollution, improper fermentation temperature control and other reasons. Therefore, it is necessary to test the heavy metal content in the liquor before drinking it, because the liquor on the surface of the liquor can reflect the heavy metal content of the part of the liquor in contact with the air, and the heavy metal content in the middle of the liquor represents the heavy metal content of the main body of the liquor. There may be some sediment at the bottom of the liquor, which can reflect the precipitation of heavy metals in the liquor. Therefore, it is necessary to sample and test the top, middle and bottom of the liquor. When sampling the liquor, the staff first needs to pull down the fixed plate at the bottom of the telescopic member 2 to stretch the telescopic member 2 to its maximum length. The telescopic end of the telescopic rod 21 will also move downward to its longest position, and then the lid of the liquor jar will be opened. The staff will hold the first fixed plate 11 and put the telescopic member 2 into the liquor liquid. The telescopic member 2 will move downward until the fixed plate at the bottom of the telescopic member 2 contacts the inner bottom of the liquor jar. Then the staff can hold the first fixed plate 11 and press downward according to the height of the liquor. Because the fixed plate at the bottom of the telescopic member 2 has contacted the bottom of the liquor jar, the fixed end of the telescopic rod 21 will move downward under pressure, and the folding rod of the telescopic member 2 will fold. When the first fixed plate 11 moves to the bottle mouth of the liquor jar, the downward pressing of the first fixed plate 11 will be stopped. At this time, the shortest first hose 14 is close to the top of the liquor. The medium-length first hose 14 is located in the middle of the liquor, and the longest first hose 14 is located at the bottom of the liquor. Then the liquid pump 18 can be started. The liquid pump 18 extracts liquor from the liquor through the first hose 14, and the liquor enters the sample tank 17 through the third hose 16. After the sampling is completed, the liquid pump 18 can be closed. At this time, the liquor located at the top, middle and bottom of the liquor tank will be stored in the sample tank 17 in turn. Then the detector 1 can be started, and the detector 1 will extract liquor samples from the sample tank 17 in turn for testing. After the test is completed, the first fixed plate 11 can be held to pull the telescopic member 2 out of the wine tank, and then the lid can be put back on the liquor bottle. After the test is completed, it can be moved to the outside. Rotate the fixing frame 19, the fixing frame 19 rotates outward, the rotation of the fixing frame 19 will drive the bottom plate 110 to move upward, then the sample jar 17 can be taken out and cleaned, and then the cleaned sample jar 17 can be put back on the bottom plate 110, under the action of gravity of the sample jar 17, the bottom plate 110 will move downward, the downward movement of the bottom plate 110 will drive the fixing frame 19 to rotate inward, the fixing frame 19 will re-lock the sample jar 17, repeat the above operation, and the heavy metal detection can be carried out on the wine in different wine jars. In this way, the liquor at the top, middle and bottom can be sampled and tested at one time to ensure the accuracy of the sampling position. It can also adapt to wine jars of different depths, so that sampling at three positions can be conveniently carried out at the same time.

[0043] Embodiment 2: Based on embodiment 1, Figure 8-Figure 11As shown, it also includes a fixing mechanism for fixing the device to the mouth of the wine cylinder, the fixing mechanism includes a rotating disk 3, a connecting rod 31, a clamping member 32, a first spring 33, a connecting ring 34, a second fixing member 35, a ratchet 36, a torsion spring 37, an extrusion block 38 and a second spring 39. Three slide rails are provided on the first fixing disk 11, and the three slide rails are evenly and equidistantly distributed. The connecting rod 31 is slidably connected to the slide rails of the first fixing disk 11, and the clamping members 32 are slidably connected to the end of the connecting rod 31 away from the first fixing disk 11. A sliding groove is provided on the clamping member 32, one end of the first spring 33 is fixedly connected to the clamping member 32, and the other end of the first spring 33 is fixedly connected to the connecting rod 31. The rotating disk 3 is rotatably connected above the first fixing disk 11, and three arc grooves are provided on the rotating disk 3. The arc grooves on the rotating disk 3 are extruded and matched with the connecting rod 31. The ratchet 36 is fixedly connected to On the rotating disk 3, a torsion spring 37 is wound on the fixed rod 12, one end of the torsion spring 37 is fixedly connected to the rotating disk 3, and the other end of the torsion spring 37 is fixedly connected to the fixed rod 12. Three second fixing members 35 are fixedly connected to the fixed rod 12, and the three second fixing members 35 are on the same horizontal plane. A straight groove is provided on the second fixing member 35, wherein two second fixing members 35 are provided with two straight grooves, and another second fixing member 35 is provided with a straight groove. The extrusion blocks 38 are respectively slidably connected to the straight grooves of the second fixing members 35, and the extrusion blocks 38 are extruded and matched with the ratchet 36. The connecting ring 34 is slidably connected between the five extrusion blocks 38. One end of the third spring 301 is fixedly connected to the connecting ring 34, and the other end of the third spring 301 is fixedly connected to the extrusion block 38. The five second springs 39 are fixedly connected between the second fixing member 35 and the connecting ring 34.

[0044] In the process of using the device for testing, people need to support the entire device by hand, which consumes manpower. Therefore, a fixing mechanism is set to fix the device on the bottle mouth of the wine jar. The working principle of the fixing mechanism is as follows: Figure 8As shown, the clamping member 32 is at the outermost end of the connecting rod 31. When sampling liquor, the telescopic member 2 needs to be placed in the liquor jar, and the connecting rod 31 will be placed on the bottle mouth of the liquor jar. At this time, the staff can rotate the rotating disk 3 clockwise. During the clockwise rotation of the rotating disk 3, the torsion spring 37 will gradually accumulate force, and the arc groove on the rotating disk 3 will squeeze the connecting rod 31. Under the squeezing action of the arc groove, the connecting rod 31 will move inward, and the inward movement of the connecting rod 31 will drive the clamping member 32 to move inward as well. The clockwise rotation of the rotating disk 3 will drive the ratchet 36 to rotate clockwise as well. The clockwise rotation of the ratchet 36 will squeeze the squeezing block 38. Under the squeezing action of the ratchet 36, the squeezing block 38 The third spring 301 will be compressed, and the squeezing block 38 will not block the rotating ratchet 36. In the process of the clamping member 32 moving inward, the clamping member 32 will contact and squeeze the outer wall of the bottle mouth of the wine jar. At the same time, the outer wall of the wine jar will also produce a reaction force on the clamping member 32. Because the outer wall of the bottle mouth of the wine jar is an arc surface, the clamping member 32 will move downward, making the clamping member 32 fit more closely to the wine jar. The first spring 33 is compressed, and the clamping member 32 fits the outer wall of the wine jar to stabilize the entire device at the bottle mouth of the wine jar. At this time, the rotation of the rotating disk 3 can be stopped, and the extended third spring 301 will extend. The extension of the third spring 301 will drive the squeezing block 38 to move inward and reset The squeezing block 38 moves inward to lock the ratchet 36. After the device is stabilized, the liquor can be sampled and tested. After the test is completed, the device needs to be removed from the wine tank. At this time, the staff needs to move the connecting ring 34 upward. At this time, the second spring 39 will extend, and the upward movement of the connecting ring 34 will drive the squeezing block 38 to move upward. The upward movement of the squeezing block 38 no longer restricts the ratchet 36, and the torsion spring 37 will be converted from the stored force state to the released pressure state. The torsion spring 37 will drive the rotating disk 3 to rotate counterclockwise. During the counterclockwise rotation of the rotating disk 3, the arc groove of the rotating disk 3 will squeeze the connecting rod 31. Under the squeezing action of the arc groove, the connecting rod 31 will move outward, and the connecting rod 3 The movement of the clamping member 32 will drive the clamping member 32 to move outward and reset. During the movement of the clamping member 32 outward, the clamping member 32 will be separated from the outer wall of the wine jar. At this time, the compressed first spring 33 will stretch, and the clamping member 32 will move outward and reset and no longer stabilize the device at the mouth of the wine jar. The staff can no longer pull the connecting ring 34. At this time, the stretched second spring 39 will shrink. The shrinkage of the second spring 39 will drive the connecting ring 34 to move downward and reset. The movement of the connecting ring 34 will drive the squeezing block 38 to move downward. The squeezing block 38 moving downward will re-lock the ratchet 36. Then the staff can take the device out of the wine jar. In this way, the device can be stabilized at the mouth of the wine jar, eliminating the need for manual support.

[0045] like Figure 12-14As shown, it also includes a sealing mechanism for sealing the cylinder mouth, the sealing mechanism includes a piston 4, an airbag 41, an extrusion plate 42 and an air pipe 43, the pistons 4 are fixedly connected to the inner side of the clamp 32, the pistons 4 include a piston cylinder and a piston rod, the piston cylinders are fixedly connected to the fixed rod 12, the piston cylinders are connected to the fixed rod 12, the piston rods are fixedly connected to the inner side of the clamp 32, the piston rods are slidably connected to the piston cylinder, the airbag 41 is fixedly connected to the bottom of the first fixed disk 11, three air pipes 43 are connected between the fixed rod 12 and the airbag 41, the air pipe 43 connects the airbag 41 with the fixed rod 12, the extrusion plate 42 is fixedly connected to the bottom of the first fixed disk 11, the extrusion plate 42 is located below the airbag 41, and the extrusion plate 42 is used to limit the expansion direction of the airbag 41.

[0046] When liquor is in contact with air for a long time, some components in the liquor may undergo redox reaction with oxygen in the air, which may change the chemical properties of the liquor. In addition, heavy metals may exist in the air, which may easily affect the detection of heavy metals in the surface liquor of the liquor. Because the liquor detection takes a long time, in order to reduce the contact between liquor and air, a sealing mechanism is specially provided to contact the liquor with air during the detection work. The working principle of the sealing mechanism is as follows: when the clamping member 32 moves inward to fix the device to the mouth of the wine jar, the inward movement of the clamping member 32 will drive the piston rod of the piston 4 to move inward, and the inward movement of the piston rod will squeeze the air in the piston cylinder of the piston 4 into the inside of the fixed rod 12, and the air will continue to enter the airbag 41 through the air pipe 43. Because of the squeezing The plate 42 restricts the bottom of the airbag 41. After the air enters the airbag 41, the airbag 41 will expand laterally. The expansion of the airbag 41 will block the gap between the first fixed plate 11 and the mouth of the wine jar, so that during the detection process, the air cannot contact the wine. After the detection is completed, the clamping member 32 will move outward. The movement of the clamping member 32 outward will drive the piston rod to move outward. The movement of the piston rod outward will extract the air in the airbag 41, and the extrusion plate 42 will shrink and no longer block the mouth of the wine jar. The device can be taken out of the wine jar. In this way, the airbag 41 can be automatically expanded to block the mouth of the wine jar when the device is fixed to the mouth of the wine jar, thereby preventing the air from contacting the wine for a long time, changing the chemical properties of the liquor, and preventing heavy metals in the air from affecting the detection results.

[0049] S2: Rotate the rotating disk 3, the arc groove of the rotating disk 3 will squeeze the connecting rod 31, the connecting rod 31 moves inward, the connecting rod 31 drives the clamping member 32 to move inward, the clamping member 32 is locked in the white wine cylinder, and the white wine cylinder is stabilized at the mouth of the wine cylinder;

[0050] S3: The clamping member 32 moves inwards, driving the piston rod of the piston 4 to move inwards first, squeezing the air in the piston cylinder into the airbag 41, and the airbag 41 expands laterally;
