[0017] The U-shaped support frame 403 is equipped with a suction mechanism, which includes a suction cylinder 501. The suction cylinder 501 is fixed in the U-shaped groove of the U-shaped support frame 403. The suction cylinder 501 is fixed by welding, adhesive bonding, bolt installation or snap-on installation. These fixing methods are all existing technologies and will not be described in detail here. A piston 502 is movably connected to the suction cylinder 501. A control rod 503 is fixedly connected to the top of the piston 502. The top of the control rod 503 extends to the outside of the suction cylinder 501. A suction tube 504 and a liquid collection tube 505 are fixedly connected to the bottom of the suction cylinder 501. A first one-way valve 506 is installed at the bottom of the suction tube 504. The first one-way valve 506 can ensure that air or liquid can only flow unidirectionally into the suction cylinder 501 through the suction tube 504. A second one-way valve 507 is installed on the liquid collection tube 505. The second one-way valve 507 can ensure that water or air can only flow unidirectionally from the suction cylinder 501 to the outside through the liquid collection tube 505.

[0018] A vertical tube 6 is fixedly connected to the outer surface of the suction tube 504, and a water-containing ball 7 is fixedly connected to the bottom of the vertical tube 6. The bottom of the suction tube 504 passes through the vertical tube 6 and extends into the interior of the water-containing ball 7. A water sample settling container 3 is provided on the top of the support base 1. The water sample settling container 3 is made of transparent material, which allows for better observation of the settling state of the water sample inside the water sample settling container 3 and the position of the water-containing ball 7 inside the water sample settling container 3. The water-containing ball 7 is located inside the water sample settling container 3.

[0019] The bottom of the water-containing ball 7 is fixedly connected to a water inlet 701. The inside of the water-containing ball 7 is provided with a sealing mechanism for sealing the water inlet 701. The sealing mechanism includes a horizontal plate 801.

The top of the control pull rope 9 passes through the horizontal plate 801, the vertical tube 6 and the bent guide sleeve 10 in sequence and is fixedly connected to an extension 11. The radius of the extension 11 is larger than the radius of the bent guide sleeve 10, so that the end of the control pull rope 9 will not be retracted into the bent guide sleeve 10.

[0021] The working principle of the water sample static separation device provided by this utility model is as follows: The contact plate 405 is moved by manually rotating the control screw 404. When the contact plate 405 and the vertical support frame 2 are separated, the sliding sleeve 401 can move up and down. The sliding sleeve 401 drives the U-shaped support frame 403 and the suction cylinder 501 to move up and down through the support plate 402. The suction cylinder 501 drives the vertical tube 6 and the water-holding ball 7 to move up and down. The water-holding ball 7 is placed in the middle position of the water sample static container 3. Then the contact plate 405 is pressed against the vertical support frame 2 to position the sliding sleeve 401, the suction cylinder 501 and the water-holding ball 7. After the water sample in the water sample settling container 3 has settled, hold the suction cylinder 501 with one hand and pull the extension part 11 with the other hand. The extension part 11 pulls the connecting ring 803 upward through the control pull rope 9, and drives the sealing plug 804 to move upward. At this time, the water sample in the middle part of the water sample settling container 3 will enter the water-containing ball 7. Then, align the external sample collection container with the end of the liquid collection tube 505, and pull the control lever 503 upward to move the piston 502 upward. When the piston 502 moves upward, the water sample inside the water-containing ball 7 can be drawn through the suction tube 504 and enter the suction cylinder 501. Then, press the control lever 503 to move the piston 502 downward, and output the water sample inside the suction cylinder 501 through the liquid collection tube 505 to the external sample collection container, thus completing the sampling of the water sample after standing.

[0022] Compared with related technologies, the water sample static separation device provided by this utility model has the following beneficial effects: This invention, by setting a water-containing ball 7 in a water sample settling container 3, and after the water sample in the water sample settling container 3 has settled, opening the sealing plug 804, allows the water sample in the middle part of the water sample settling container 3 to enter the water-containing ball 7, and then drawing the water sample in the water-containing ball 7 into the suction cylinder 501, and finally outputting it through the liquid collection tube 505 to complete the sampling, can avoid the sediment at the bottom of the water sample settling container 3 or the oily substances at the top of the water sample, and prevent some oily substances on the surface from entering the sampling tube when the tube is inserted into the water sample settling container 3 for sampling, thus preventing oily substances in the sampled water sample from contaminating the instrument or forming an emulsion that interferes with the analysis.
