[0023] As Figures 1 to 3 shown, a sampling device for water sample detection provided by a specific embodiment of the present utility model includes a sampling tank 1, a pressing component 2, an adjusting internal threaded tube 3, a through hole 4 of the internal threaded tube, a sampling water inlet 5, a movable adjusting component 6 and a pressing elastic part 7. The pressing component 2 is arranged inside the middle of the sampling tank 1, the adjusting internal threaded tube 3 is fixedly arranged inside the middle of the sampling tank 1, the through hole 4 of the internal threaded tube is opened in the middle below the adjusting internal threaded tube 3, the sampling water inlet 5 is opened at the bottom of the sampling tank 1, the movable adjusting component 6 is slidably connected outside the pressing component 2 in a limited manner, and the pressing elastic part 7 is arranged between the pressing component 2 and the movable adjusting component 6.

[0024] In some optional specific embodiments, such as Figure 1 , Figure 2 and Figure 6As shown, it also includes a lifting ring adapter 8, a sampling handle 9 and a limiting bolt 10. The lifting ring adapter 8 is fixedly arranged above both sides of the sampling tank 1, and the sampling handle 9 is sleeved on the lifting ring adapter 8 for connection. The limiting bolt 10 is threadedly connected to the internal screw hole structure of the lifting ring adapter 8, and also includes a connection through hole 11 and a lifting clamp 12. The connection through hole 11 is opened inside the two ends below the sampling handle 9 and is adapted to the lifting ring adapter 8. The lifting clamp 12 is fixedly arranged in the middle above the sampling handle 9. By putting the connection through hole 11 below the sampling handle 9 on the lifting ring adapter 8 and limiting it by the limiting bolt 10, the lifting rope can be passed through the lifting clamp 12 to conveniently perform sampling work, and the structure can be easily disassembled and replaced while ensuring firmness.

[0025] In some optional specific embodiments, such as Figure 4 As shown, the pressing assembly 2 includes a pressing adjustment rod 201, a pressing lower plate 202 and an adjustment limit strip 203. The pressing lower plate 202 is fixedly arranged below the pressing adjustment rod 201, and the adjustment limit strip 203 is evenly fixed around the three ends of the side of the pressing adjustment rod 201.

[0026] In some optional specific embodiments, such as Figure 5 As shown, the movable adjustment component 6 includes an adjustment block 601, an adjustment rod socket 602 and an adjustment limit groove 603. The adjustment rod socket 602 is located in the middle of the adjustment block 601 and is opened through. The adjustment limit groove 603 is located in the three ends of the side of the adjustment rod socket 602 and is evenly surrounded. The adjustment limit strip 203 is engaged with the adjustment limit groove 603, thereby driving the movable adjustment component 6 to rotate inside the adjustment internal threaded tube 3. At this time, since the outer side of the adjustment block 601 is provided with a thread screwed to the adjustment internal threaded tube 3, it can be located in the adjustment internal threaded tube 3 to adjust the upper and lower distances. At the same time, since the compression adjustment rod 201 movably passes through the adjustment rod socket 602, it will not be stuck, so that the compression degree of the compression elastic member 7 can be adjusted.

[0027] Working principle of the present utility model: During use, according to the depth required for sampling, rotate the pressing assembly 2. By adjusting the engagement of the limiting strip 203 with the limiting groove 603, the movable adjustment assembly 6 is driven to rotate inside the adjusting internal threaded tube 3. At this time, since the outer side of the adjusting block 601 is provided with threads screwed to the adjusting internal threaded tube 3, it can adjust the vertical distance inside the adjusting internal threaded tube 3. At the same time, since the pressing adjustment rod 201 movably penetrates the adjustment rod insertion hole 602, it will not cause jamming. In this way, the compression degree of the pressing elastic member 7, that is, the pressing force on the pressing lower plate 202, can be adjusted. When the sampling tube enters the water to a certain depth and the water pressure is greater than the elastic force of the pressing elastic member 7, the water liquid will enter the sampling tank 1 through the sampling water inlet 5. And it is necessary to maintain a certain sealing performance for the gap between the pressing assembly 2 and the movable adjustment assembly 6, which can be achieved by setting a rubber layer on their contact surfaces. And before putting the sampling tank 1 into the water, a certain amount of internal air of the sampling tank 1 needs to be pumped out first, so as to achieve the sampling work. During sampling, the transfer through hole 11 below the sampling rotating handle 9 is sleeved on the hanging ring transfer seat 8 and limited by the limiting bolt 10. In this way, the sampling work can be conveniently carried out by threading a lifting rope through the lifting clamp ring 12. And the structure can be conveniently disassembled and replaced while ensuring firmness.
