The effect is achieved that the U-shaped plate 205 rotates around the flange bearing 204 to drive the spring 206 to move, so that the arc-shaped baffle 208 drives the arc-shaped sealing pad 209 to move away from or close to the through port 202. Three round rods 207 are fixedly connected to one side of the arc-shaped baffle 208. The arc surfaces of the three round rods 207 are slidably connected to the U-shaped plate 205. The effect is achieved that the round rods 207 slide on the U-shaped plate 205 to drive the arc-shaped baffle 208 to move. A handle 210 is fixedly connected to one side of the U-shaped plate 205. The effect is achieved that the handle 210 drives the U-shaped plate 205 to move. A round block 211 is fixedly connected to one end of the sampling tube 201. The arc surface of the round block 211 is slidably connected to the U-shaped plate 205. The effect is achieved that the round block 211 prevents the position of the U-shaped plate 205 from shifting during the rotation around the sampling tube 201. An arc-shaped groove plate 213 is fixedly connected to the arc surface of the sampling tube 201. Two guide rods 214 are slidably connected inside the arc-shaped groove plate 213. One end of the four guide rods 214 is fixedly connected to the arc-shaped baffle 208. The effect is achieved that the movement of the arc-shaped baffle 208 drives the guide rods 214 to slide inside the arc-shaped groove plate 213.

[0035] Referring to Figure 4 As shown in the figure, in this embodiment: The moving device 3 includes two fixing plates 31. The sides of the two fixing plates 31 close to each other are fixedly connected to the arc-shaped baffle 208. A card slot 32 is provided on one side of the fixing plate 31.

The effect is achieved that the limiting plates 36 prevent the position of the arc-shaped frame 34 from shifting during the movement.

[0036] Working principle: Through the fixing device 2, when water quality sample extraction is required, first, the operator holds the handle 1 and drives the sampling pipe 201 to move above the position where water needs to be taken. Then, the sampling pipe 201 is immersed in water, and the pull handle 210 is pulled, causing the pull handle 210 to drive the U-shaped plate 205 to rotate around the flange bearing 204. During the movement of the U-shaped plate 205, the round rod 207 and the spring 206 are driven to move, so that the arc-shaped baffle 208 drives the arc-shaped gasket 209 away from the through port 202. When the arc-shaped gasket 209 no longer covers the through port 202, water flows through the through port 202 into the sampling chamber 203. After sampling is completed, the rubber gasket can cover the through port 202 to prevent the sampled water from flowing out of the sampling chamber 203. Through the fixing device 2, the problem of traditional water quality water sample detection sample extraction equipment, which mostly takes water once and cannot achieve multi-batch sampling in one water entry, resulting in the need for repeated sampling, cumbersome operation, time-consuming, and low sampling efficiency, is solved.

[0037] Through the moving device 3, when it is necessary to prevent foreign matters in water from flowing into the sampling chamber 203 during water quality sampling, first, the operator installs the fixing plate 31 on the arc-shaped baffle 208, and then inserts the rubber rod 33 fixed on the arc-shaped frame 34 into the card slot 32, so that the filter screen 35 blocks the through port 202. When water flows through the through port 202 into the sampling chamber 203, the foreign matters in the water are isolated by the filter screen 35. Through the moving device 3, the problem that traditional water quality water sample detection sample extraction equipment does not have a filter screen 35, resulting in foreign matters in water flowing into the sampling chamber 203 together with water during sampling, is solved.
