One side of the inner wall of the storage shell 1 is fixedly connected to the guide plate 9 used in conjunction with the extension frame 4;

[0030] The pushing assembly 10 is fixed to one side of the storage shell 1, and the pushing assembly 10 is used to push the liquid collector body 8. The pushing assembly 10 includes a fixing plate 1001 and a fixing rod 1002. A piston rod 11 is provided inside the collecting shell 3. The piston rod 11 cooperates with a sealing plug 12 and a liquid collection assembly 13 to conveniently draw the liquid into the collecting shell 3 through the collecting tube 31. A sealing plug 12 is fixedly connected to one side of the piston rod 11, and a liquid collection assembly 13 is provided on the surface of the piston rod 11. The liquid collection assembly 13 includes a guide rod 1301, a fixing frame 1302, a gear 1303 and a gear block 1304.

[0031] An observation window 14 is fixedly connected to one side of the storage shell 1, through which the transportation status of the liquid collector body 8 can be conveniently observed. A leakage hole 15 for use with the liquid collector body 8 is opened between the inner walls of the storage shell 1 and the collection shell 3, through which the collected liquid can be discharged to the inside of the liquid collector body 8 for collection.

[0032] The guide rod 1301 is slidably connected to the inside of the collection shell 3, the fixed frame 1302 is fixed to the surface of the piston rod 11, the end of the gear 1303 is rotatably connected to the inner wall of the collection shell 3 through a bearing, the tooth block 1304 is respectively fixed to one side of the fixed frame 1302 and the guide rod 1301, and is meshed with the gear 1303, and one side of the fixed frame 1302 is fixedly connected to the limit rod 1305. First, when the user needs to collect liquid, the collection tube 31 is placed in the collection position, and then the guide rod 1301 is pushed. As the guide rod 1301 moves, the tooth block 1304 is driven to mesh. Gear 1303, at this time, gear 1303 will engage with the tooth block 1304 on the fixed frame 1302, and the fixed frame 1302 will drive the piston rod 11 to move. As the piston rod 11 moves, the sealing plug 12 will move, thereby drawing the liquid into the interior of the collection shell 3, and when the fixed frame 1302 moves, the first spring 1306 will be squeezed, and the subsequent resetting work will also be convenient. The end of the limit rod 1305 away from the fixed frame 1302 passes through the outside of the collection shell 3, and the first spring 1306 is fixedly connected between one side of the fixed frame 1302 and the inner wall of the collection shell 3.

[0033] The retaining plate 1001 is fixed on both sides of one side of the storage shell 1, and the retaining rod 1002 is fixed between the two retaining plates 1001. The surface of the retaining rod 1002 is slidably connected with a pushing plate 1003. When the user needs to push the liquid collector body 8 between the extension frame 4 and the guide plate 9 to the inside of the limiting assembly 7, the pushing plate 1003 can be pushed to move on the surface of the retaining rod 1002. As the pushing plate 1003 moves, the second spring 1004 will be assisted in resetting, and as multiple liquid collector bodies 8 are pressed against each other, the edgemost liquid collector body 8 will be squeezed into the inside of the limiting assembly 7 to take liquid. One side of the pushing plate 1003 is fixedly connected with the retaining plate 1001 with a second spring 1004, and one side of the pushing plate 1003 is in pressure contact with the liquid collector body 8.

[0034] A retaining frame 16 is fixedly connected to one side of the top of the inner cavity of the storage shell 1. When the user needs to take out the liquid collecting body 8 after sampling from the inside of the collection shell 3, the pull rod 18 can be pulled. As the pull rod 18 moves, the pushing ring 17 will be driven to move within the internal limit position of the retaining frame 16, and the third spring 19 will be stretched during the movement of the pushing ring 17. When the pull rod 18 is released, the retaining frame 16 will slowly assist in resetting. At this time, the pushing ring 17 will press the liquid collecting body 8 between the arc-shaped clamping ring 704 and the first limit frame 701 to make it easier for the staff to take it out. The internal sliding connection of the retaining frame 16 is the pushing ring 17, and one side of the pushing ring 17 is fixedly connected to the pull rod 18. One side of the pushing ring 17 is connected to the storage A third spring 19 is fixedly connected between the inner walls of the shell 1, a fourth spring 20 is fixedly connected to one side of the observation window 14, and a sensing block 21 is fixedly connected to one side of the fourth spring 20. Through the fixation of the fourth spring 20 and the sensing block 21, when the next set of limit assemblies 7 moves to the position of the next leakage hole 15, the pushing assembly 10 is used to push the liquid collector body 8 to between the arc-shaped clamping ring 704 and the first limit frame 701. At this time, the sensing block 21 will be pressed by the liquid collector body 8 and squeeze the fourth spring 20. Then the sensing block 21 will also extend a little, so that the staff can know that the sampling position has been calibrated. One side of the sensing block 21 is fixedly connected to a sensing rod 22 that is observed to the outside of the observation window 14.

[0035] A rotating rod 23 is fixedly connected to one side of the meshing wheel 5. One end of the rotating rod 23 passes through the outside of the storage shell 1 and is fixedly connected to a twisting block 24. A concave disk 25 is sleeved on the surface of the rotating rod 23. The rotating rod 23 can be driven to rotate by rotating the twisting block 24. As the rotating rod 23 rotates, the meshing wheel 5 is driven to mesh with the transmission belt 6 for transportation. When the twisting block 24 rotates, the extension plate 26 is driven and the positioning rod 27 is cooperated to make the oblique insertion block 28 inserted into the inside of the concave disk 25. As the oblique insertion block 28 moves, the fifth spring 29 is frequently squeezed, thereby achieving the effect of a ratchet, and the twisting block 24 can be prevented from reversing during the liquid extraction process. One side of the concave disk 25 is connected to the rotating rod 23. The side is fixedly connected to the storage shell 1, one side of the torsion block 24 is fixedly connected with an extension plate 26, the interior of the extension plate 26 is slidably connected with a positioning rod 27, one side of the positioning rod 27 is fixedly connected with an oblique insertion block 28 used in conjunction with the concave disk 25, one side of the oblique insertion block 28 is fixedly connected with a fifth spring 29 between the extension plate 26, and one side of the positioning rod 27 is fixedly connected with a lever 30 used to flip the torsion block 24. When the user needs to reverse the turning rod 23, the lever 30 can be moved to make the positioning rod 27 drive the oblique insertion block 28 to squeeze the fifth spring 29, and make the oblique insertion block 28 separate from the interior of the concave disk 25, so that the torsion block 24 can be reversed.

[0036] The first limit frame 701 is fixed on the surface of the transmission belt 6, and the second limit plate 702 is symmetrically fixed on one side of the transmission belt 6. The second limit plate 702 is internally slidably connected with a connecting rod 703. When the liquid collector body 8 is moved by the pushing assembly 10, the liquid collector body 8 will be between the first limit frame 701 and the arc-shaped clamping ring 704, and the arc-shaped clamping ring 704 will be driven by the force to move the connecting rod 703 and squeeze the sixth spring 705, so as to force the liquid collector body 8 to be clamped and positioned between the first limit frame 701 and the arc-shaped clamping ring 704 to prevent misalignment during liquid collection. One end of the connecting rod 703 is fixedly connected with the arc-shaped clamping ring 704, and the sixth spring 705 is fixedly connected between one side of the connecting rod 703 and the arc-shaped clamping ring 704.

[0037] Working principle: first, when the user needs to collect liquid, the collection tube 31 is placed in the collection position, and then the guide rod 1301 is pushed. As the guide rod 1301 moves, the tooth block 1304 is driven to engage the gear 1303. At this time, the gear 1303 will engage the tooth block 1304 on the fixed frame 1302. At this time, the fixed frame 1302 will drive the piston rod 11 to move. As the piston rod 11 moves, the sealing plug 12 will move, thereby drawing the liquid into the collection shell 3. When the fixed frame 1302 moves, the first spring 1306 will be squeezed, and the subsequent resetting work will also be convenient. At this time, the extracted liquid will flow into the interior of the liquid collector body 8 through the leakage hole 15 for storage, and penetrate with the observation window 14. When needed When the liquid collector body 8 is to be replaced, the rotating rod 23 can be driven to rotate by rotating the twist block 24. As the rotating rod 23 rotates, the meshing wheel 5 is driven to mesh with the transmission belt 6 for transportation. When the twist block 24 rotates, the extension plate 26 is driven and the positioning rod 27 is cooperated to make the oblique insertion block 28 inserted into the inside of the concave plate 25. As the oblique insertion block 28 moves, the fifth spring 29 is frequently squeezed, thereby achieving the ratchet effect and preventing the twist block 24 from reversing during the liquid extraction process. At this time, the limit assembly 7 on the transmission belt 6 will move and make the other two first limit frames 701 and the arc-shaped clamping ring 704 stay at the bottom of the leakage hole 15. Then, when the user needs to push the liquid collector body 8 between the extension frame 4 and the guide plate 9 into the limit assembly 7 for When replacing, the push plate 1003 can be pushed to move on the surface of the fixing rod 1002. As the push plate 1003 moves, the second spring 1004 will be assisted in resetting, and as multiple liquid collector bodies 8 are pressed against each other, the edge of the liquid collector body 8 will be squeezed between the arc-shaped clamping ring 704 and the first limiting frame 701. Then, at this time, the arc-shaped clamping ring 704 will be forced to squeeze the sixth spring 705, thereby forcing the liquid collector body 8 to be clamped and positioned between the first limiting frame 701 and the arc-shaped clamping ring 704 to prevent misalignment during liquid collection. Then, when the liquid collector body 8 is limited inside the first limiting frame 701 and the arc-shaped clamping ring 704, the sensor block 21 will be pressed by the liquid collector body 8 and squeeze the fourth spring 20, and then the sensor block 21 will also It will extend a little, so that the staff can know that the sampling position has been calibrated and can pass through the observation window 14, and then perform the liquid collection work again. After multiple rounds of liquid collection, the liquid collector body 8 will eventually be at the rightmost side of the storage shell 1. At this time, when the user needs to take out the liquid collector body 8 after sampling from the inside of the collection shell 3, the pull rod 18 can be pulled. As the pull rod 18 moves, the push ring 17 will be driven to move within the internal limit of the retaining frame 16, and the third spring 19 will be stretched during the movement of the push ring 17. When the pull rod 18 is released, the retaining frame 16 will slowly assist in resetting. At this time, the push ring 17 will press the liquid collector body 8 between the arc-shaped clamping ring 704 and the first limit frame 701 to facilitate the staff to take it out.
