The driving unit 5 is slidably connected in the sampling ring tube 11 and connected to the pushing unit 4 , and is used for cooperating with the pushing unit 4 to realize the opening and closing of the opening and closing unit 3 .

In an embodiment of the present invention, when sampling and testing the purified water quality of a printing and dyeing wastewater treatment station, the sampling vehicle 1 is first moved to the sampling location, and the lifting unit 2 is turned on, so that the lifting unit 2 drives the sampling ring tube 11 to rise and fall. When the sampling ring tube 11 enters the water body, with the cooperation of the driving unit 5 and the pushing unit 4, multiple groups of opening and closing units 3 will be opened in sequence, so that the water body in the sampling ring tube 11 can pass through each group of opening and closing units 3 in sequence and enter the corresponding sampling chamber 111. After the water body enters the sampling chamber 111, the opening and closing unit 3 can be automatically closed, thereby realizing multi-component layered sampling of the water body, ensuring the sealing of the water body in the sampling chamber 111, and preventing the water body from being spilled or contaminated.

In one embodiment of the present invention, as shown in FIG1 , the lifting unit 2 comprises:

A wire take-up drum 21 is rotatably connected to the sampling vehicle 1, and a pull rope 23 is wound around the surface of the wire take-up drum. The end of the pull rope 23 is connected to the sampling ring tube 11.

The driving member 22 is installed on the sampling vehicle 1, and the end of the take-up reel 21 is connected to the output end of the driving member 22;

The avoidance hole 24 is provided on the sampling vehicle 1 , and the sampling loop tube 11 is slidably connected in the avoidance hole 24 .

In this embodiment, when sampling and testing the purified water quality of the printing and dyeing wastewater treatment station, the sampling vehicle 1 is first moved to the sampling location, and the driving member 22 is turned on. The output end of the driving member 22 can drive the take-up reel 21 to rotate, so that the take-up reel 21 can unwind the pull rope 23, so that the sampling ring tube 11 can pass through the avoidance hole 24 into the water body, which is convenient for the sampling chamber 111 in the sampling ring tube 11 to sample and test the water body.

In one embodiment of the present invention, as shown in FIG. 1 and FIG. 2 , the sampling chamber 111 is distributed in at least three layers in the sampling ring tube 11 , and water inlet holes 114 are opened at both ends of the sampling ring tube 11 .

In this embodiment, there are ten groups of sampling chambers 111 distributed in a circle in the sampling ring tube 11. When the sampling ring tube 11 enters the water body, the water body can flow into the sampling ring tube 11 through the water inlet hole 114, and enter the ten groups of sampling chambers 111 in sequence through the opening and closing unit 3. By setting up ten groups of sampling chambers 111, multiple groups of samples can be obtained at one time, so that different indicators of the water bodies in the ten groups of sampling chambers 111 can be detected respectively. At the same time, the sampling chambers 111 are distributed in at least three layers in the sampling ring tube 11, so that water bodies at different depths can be detected, thereby achieving the purpose of stratified sampling of sewage.

In one embodiment of the present invention, as shown in FIG. 3 and FIG. 5 , the opening and closing unit 3 includes:

A water inlet 31 is provided on the side of the sampling chamber 111;

A chute 32 is provided inside the water inlet 31 and is slidably connected with a sealing plate 33;

The elastic member 34 is connected between the end of the sealing plate 33 and the inner wall of the sliding groove 32 .

In this embodiment, when the sampling ring tube 11 enters the water body, the water can flow into the interior of the sampling ring tube 11 through the water inlet hole 114. At this time, the sealing plate 33 can slide inward in the slide groove 32 with the cooperation of the pushing unit 4 and the driving unit 5, so that the two groups of sealing plates 33 move away from each other until the water inlet 31 is opened, so that the water in the sampling ring tube 11 can flow into the corresponding sampling chamber 111 through each group of water inlet 31.

In the above process, the two sets of sealing plates 33 can respectively compress the elastic member 34 in the slide groove 32 when sliding. An exhaust pipe 113 is installed in each set of sampling chambers 111, and the air in the sampling chamber 111 can be discharged through the exhaust pipe 113 during the sampling process of the sampling chamber 111.

In one embodiment of the present invention, as shown in FIGS. 4 and 5 , the pushing unit 4 includes:

A rotating rod 41 is rotatably connected in the sampling ring tube 11, and a sliding rod 42 is fixed on the surface;

A sliding frame 43 is slidably connected to the surface of the sliding rod 42, and the sliding frame 43 and the rotating rod 41 are connected via an elastic member 44;

A top frame 431 is fixed to the side of the sliding frame 43;

The inclined groove 45 is provided at the end of the sealing plate 33 , and the surface is slidably connected to the top frame 431 .

In this embodiment, after water flows into the sampling ring tube 11 through the water inlet hole 114, the driving unit 5 can drive the rotating rod 41 to rotate in the sampling ring tube 11, so that the rotating rod 41 can drive the sliding frame 43 to rotate through the sliding rod 42, so that the sliding frame 43 drives the top frame 431 to slide on the inner wall of the sampling ring tube 11. When the top frame 431 slides to contact the inclined groove 45, the sliding frame 43 will slide outward on the surface of the sliding rod 42 under the elastic force of the elastic object 44, so that the sliding frame 43 drives the top frame 431 to squeeze the inclined groove 45. The inclined groove 45 will drive the sealing plate 33 to compress the elastic member 34 in the sliding groove 32 under the squeezing of the top frame 431, so that the two groups of sealing plates 33 will move away from each other until the water inlet 31 is opened, and the water can enter the sampling chamber 111 through the water inlet 31.

The elastic object 44 and the elastic member 34 can be springs or elastic rubbers, and the elastic force of the elastic object 44 is much greater than the elastic force of the elastic member 34 .

In one embodiment of the present invention, as shown in FIG. 3 and FIG. 4 , the driving unit 5 includes:

The fixed cylinder 51 is fixed in the sampling ring tube 11 and is slidably connected with a lifting rod 52;

The rotating cylinder 57 is connected to the side of the second gear 56 and has an arc groove 571 on its surface;

The sliding column 54 is fixed on the side of the lifting rod 52 and is slidably connected in the arc groove 571.

In this embodiment, when testing a water body, the buoyancy ring 53 is first pressed downward so that the buoyancy ring 53 slides to the inner bottom of the sampling loop tube 11 .

When the sampling ring tube 11 enters the water body, the water flows into the sampling ring tube 11 through the water inlet hole 114. At this time, the buoyancy ring 53 will drive the lifting rod 52 to slide upward in the fixed tube 51 under the action of the buoyancy of the water, and the lifting rod 52 can drive the sliding column 54 to rise synchronously. Since the surface of the sliding column 54 is slidingly connected in the arc groove 571, the rotating cylinder 57 will drive the second gear 56 to rotate in the sampling ring tube 11 under the action of the arc groove 571 and the sliding column 54, so that the second gear 56 can drive the rotating rod 41 to rotate in the sampling ring tube 11 through the connection with the first gear 55.

The rotating rod 41 can drive the sliding rod 42 and the sliding frame 43 on both sides thereof to slide, so that the sliding frame 43 drives the top frame 431 to slide on the inner wall of the sampling ring tube 11, so that the top frame 431 will slide to each group of water inlets 31 in turn, and contact with the sealing plate 33 in each water inlet 31, so that each group of sealing plates 33 will be opened in turn under the action of the inclined groove 45 and the top frame 431, so that the water body can flow into each sampling chamber 111 through the water inlet 31 in turn, thereby completing the sampling of the water body.

When the top frame 431 slides away from the sealing plate 33, the two sets of sealing plates 33 will move closer to each other under the elastic force of the elastic member 34, thereby sealing the water inlet 31. The sampling chamber 111 is equipped with a water outlet valve 112, and the water outlet valve 112 can be opened to detect the discharge of water in the sampling chamber 111.

The working principle of the present invention is: when sampling and testing the water quality after purification in a printing and dyeing wastewater treatment station, first move the sampling vehicle 1 to the sampling location, turn on the lifting unit 2, so that the lifting unit 2 can drive the sampling ring tube 11 into the water body. After the sampling ring tube 11 enters the water body, the water body can flow into the sampling ring tube 11 through the water inlet hole 114, and enter the ten groups of sampling chambers 111 in turn through the opening and closing unit 3. By setting up ten groups of sampling chambers 111, multiple groups of samples can be obtained at one time, so that different indicators of the water bodies in the ten groups of sampling chambers 111 can be tested respectively.
