[0026] Furthermore, when the second lifting ring 13 contacts the top plate of the sampling tube 11 , the second spring 115 is in a natural state.

[0027] Furthermore, the vacuum mechanism includes a pump barrel 31 and a piston 32; the pump barrel 31 is fixedly connected to the right outer wall of the sampling barrel 11, and an exhaust pipe 33 and an exhaust pipe 34 are fixedly connected to the bottom of the pump barrel 31. The exhaust pipe 33 and the exhaust pipe 34 are respectively provided with a first one-way valve 35 and a second one-way valve 36. The first one-way valve 35 allows gas to pass through in the direction pointing to the inner cavity of the pump barrel 31, and the second one-way valve 36 allows gas to pass through in the direction away from the inner cavity of the pump barrel 31.

[0030] Furthermore, a mounting plate 26 is fixedly connected to the top of the suspension rod 118 , a U-shaped seat 27 is fixedly connected to the head of the suspension rope 119 , and the U-shaped seat 27 and the mounting plate 26 are detachably connected via bolts 28 .

[0031] Furthermore, the U-shaped seat 27 is made of a permanent magnet, and the rope pulley 22 is made of a ferromagnetic material.

[0032] Furthermore, a first storage tube 29 is fixedly connected to the base 21 , a second storage tube 210 is fixedly connected to one side of the first storage tube 29 , and a mounting ring is fixedly connected to the upper portion of the outer wall of the sampling tube 11 .

[0033] A specific embodiment of the present invention is:

[0034] like Figure 5 As shown, the sling 119 is wound around the rope pulley 22 when not in use, and the U-shaped seat 27 is adsorbed on the rope pulley 22. Different slings 119 have different lengths, so that the sling 119 of appropriate length can be used according to the depth of sampling required. After selecting the sling 119, the U-shaped seat 27 is separated from the rope pulley 22, and then the shaft 24 and the rope pulley 22 are rotated by the turntable 25 so that the selected sling 119 can be completely unwound from the rope pulley 22.

[0035] When the sampling mechanism is not in use, the sampling cylinder 11 and the pump cylinder 31 are located in the first storage cylinder 29 and the second storage cylinder 210 respectively, and the lap ring overlaps the top of the first storage cylinder 29 .

[0036] like Figure 1 and 2 As shown, under the action of the first spring 112 and the second spring 115, the first sealing seat 113 and the second sealing seat 116 are located in the water inlet 18, the pull seat 39 is rotated to separate it from the threaded sleeve 311, and then the piston 32 is driven to move up and down reciprocatingly through the handle 310, and the air in the sampling tube 11 is extracted through the exhaust pipe 33 and the first one-way valve 35, and the air is discharged through the exhaust pipe 34 and the second one-way valve 36, so that the sampling tube 11 is vacuumed.

[0037] The U-shaped seat 27 is connected to the mounting plate 26 by bolts 28 to achieve the connection of the suspension rope 119, and then the sampling mechanism is thrown into the water. During the descent of the sampling mechanism, since the suspension rope 119 has a sufficient reserved length, when the sampling mechanism descends, under the action of the second spring 115, the second sealing seat 116 is located in the water inlet 18 to prevent water from entering the sampling tube 11.

[0038] When the sampling tube 11 reaches the sampling depth, the sampling tube 11 descends due to gravity, and the lifting rope 119 pulls the lifting rod 118 and the second lifting ring 13 to maintain the same height, that is, the second lifting ring 13 rises relative to the sampling tube 11, so that the second sealing seat 116 is separated from the water inlet 18.

[0039] The sampling tube 11 has been pre-evacuated, so that the water pressure pushes the first sealing seat 113 down at the water inlet 18, and water enters the sampling tube 11. As water continues to enter, the pressure inside and outside the sampling tube 11 is balanced. Under the action of the first spring 112, the first sealing seat 113 enters the water inlet 18 to seal it.

[0040] Then, the turntable 25 drives the rope pulley 22 to rotate, and the lifting rope 119 is wound on the rope pulley 22 to lift the sampling mechanism. During the rising process, the water depth continues to decrease and the water pressure decreases, so that the first sealing seat 113 is located in the water inlet 18, ensuring that shallow water will not enter the sampling tube 11.

[0041] After the sampling tube 11 is lifted, the cover 15 is opened, and then the manual valve 17 is opened, and the outside air enters the sampling tube 11 through the connecting tube 14, so that the water sample flows out from the water outlet pipe 16.
